[0033] FIG. 1 shows a packing box 101, wherein two opposite side
covers 1011 and two main covers 1012 located between the side
covers 1011 are provided at one end of the packing box 101, the
side covers 1011 of the packing box are connected with two opposite
side plates 1013, the main covers 1012 of the packing box are
connected with two opposite main plates 1014, and a box opening
1015 of the packing box after being unfolded is generally
rectangular. The specific structures of the side covers 1011 are
different according to different packing requirements, and as shown
in FIG. 1, hooking tongues 1016 are provided on the side covers
1011. In a process of sealing the packing box, the packing box
needs to be unfolded, and after a material to be packed is placed
in, the side covers 1011 are bent, then the hooking tongues 1016
are hooked to each other, and the main covers 1012 are sealed.
[0034] With reference to FIGS. 2 and 3, a first embodiment of the
present application provides a box sealing device 1 comprising a
cover bending assembly comprising two oppositely arranged rotating
rods 11, and bending pieces 12 convexly provided at one ends of the
rotating rods 11; the two bending pieces 12 are bent towards each
other, and the bending pieces 12 are arranged at an acute angle to
the rotating rods 11.
[0035] According to the box sealing device 1 provided in the
present embodiment, when the two rotating rods 11 drive the side
covers 1011 to rotate to a preset position, the two bending pieces
12 bend the two side covers 1011 and make them form a certain
obtuse angle to allow the hooking tongues 1016 of the side covers
to hook each other to a certain extent, then the two main covers
1012 are pressed, and the two side covers 1011 are hooked
completely, so that the box sealing device 1 is simple in structure
and high in stability.
[0036] Specifically, the bending pieces 12 comprise fixing parts
121 attached to the rotating rods 11, and bending part 122 convexly
arranged on the fixing parts 121. The bending piece 12 is disposed
at an acute angle to the rotating rod 11 so that an acute angle is
formed between the bending part 122 and the rotating rod 11, and a
certain acute angle is formed between the fixing part 121 and the
bending part 122. Preferably, the fixing parts 121 are detachably
connected to the rotating rods 11. The bending pieces 12 can be
manufactured in various specifications and sizes, and during use,
the bending pieces 12 can be replaced according to the size or
model of the packing box to be adapted to different models of
packing boxes.
[0037] Preferably, the acute angle between the bending part 122 and
the fixing part 121 is 60-85 degrees. The angle between the bending
part 122 and the fixing part 121 can be adjusted according to the
shape or size of the side cover. Taking the packing box having the
side covers with hooking tongues as shown in FIG. 1 as an example,
when the two side covers form an obtuse angle of about 160 degrees,
the hooking of the hooking tongues of the two side covers would be
very stable, and when the two main covers are closed in the next
step, the two side covers are completely hooked.
[0038] As a preferred embodiment, as shown in FIGS. 4 and 5, the
bending pieces 12 comprise bending piece bodies 123 connected with
the rotating rods 11, the bending parts 122 are arranged at one
ends of the bending piece bodies 123 that away from the rotating
rods 11; the two bending parts 122 are arranged in a mutually
staggered manner, and the two bending parts 122 do not interfere
with each other during movement, so that the side covers 1011 can
be bent to the preset position. Specifically, the bending piece
bodies 123 are connected with the rotating rods 11 through the
fixing parts 121, that is, the bending piece bodies 123 connect the
fixing parts 121 and the bending parts 122. Here, the bending parts
122 are provided at one ends of the bending piece bodies 123, and
when the two rotating rods 11 move toward each other, the two
bending parts 122 bend the side covers 1011, and the two bending
parts 122 do not collide with each other due to staggered
arrangement, so that the side covers 1011 can be bent as much as
possible. The bending piece bodies 123 are formed at a
substantially right angle to the rotating rods 11, and after the
side covers 1011 are bent, the bending piece bodies 123 are
substantially fit with the side covers 1011, so that deformation of
the side covers 1011 can be prevented. An acute angle is formed
between the bending part 122 and the fixing part 121, thus, an
obtuse angle is formed between the bending part 122 and the bending
piece body 123; and after the two rotating rods 11 are moved to a
preset position, an included angle is formed between the two
bending parts 122, so that the two side covers 1011 are also
arranged at a certain included angle, and the two side covers 1011
are hooked to each other to a certain extent accordingly.
[0039] The two rotating rods 11 can be moved toward or away from
each other by rotating in a process of bending the side covers. In
particular, as shown in FIG. 4, the box sealing device 1 further
comprises a mounting bracket 111, the rotating rods 11 are hinged
to two sides of the mounting bracket 111, the rotating rods 11 are
connected with a first driving member 112 to drive the two rotating
rods 11 to move towards each other. One end of the first driving
member 112 is connected with the rotating rods 11 to drive the
rotating rods 11 to be close to or away from each other, the first
driving member 112 is rotatably connected with one ends of the
rotating rods 11 that away from the bending pieces 12, and the
other end of the first driving member 112 is connected with the
mounting bracket 111. The lengths of the rotating rods 11 may be
set as desired. It should be noted herein that the rotating rod 11
may be made of a lightweight material or be hollow to reduce the
weight. The first driving member 112 selects a clamping cylinder,
which is low in weight and cost and long in service life, and can
also be other driving forms, such as an electric cylinder or a
hydraulic cylinder, and can be selected according to
requirements.
[0040] Optionally, the two rotating rods 11 are arranged
symmetrically, and the two rotating rods 11 are coordinated to move
synchronously so as to be suitable for the packing box with the
same two side covers, ensuring simultaneous bending and hooking of
the two side covers.
[0041] As a preferred embodiment, as shown in FIG. 5, the rotating
rods 11 are further provided with first protrusion pieces 113, and
the two first protrusion pieces 113 are oppositely arranged to
limit a minimum distance between the two rotating rods 11, so that
a situation that the side covers 1011 cannot be inserted due to the
incapability of effectively applying force to the two side covers
1011 since the distance between the two rotating rods 11 is too
small and contact positions of the rotating rods 11 and the side
covers 1011 are too close to the edges of the side covers 1011 can
be prevented. Here, the first protrusion pieces 113 are bolts
provided on the rotating rods 11, and the minimum distance between
the two rotating rods 11 can be adjusted by adjusting the heights
of the bolts protruding from the rotating rods 11, thereby being
adapted to the bending and insertion requirements of the side
covers 1011 of different sizes. The number of the first protrusion
pieces 113 may be set to two, that is, one on each of the two
rotating rods 11, and the two first protrusion pieces 113 are
oppositely arranged. Specifically, each of the rotating rods 11
comprises: a rotating part 1101 rotatably connected with the
mounting bracket 111, and a rod part 1102 connected with the
rotating part 1101. The rod part 1102 is detachably connected with
the rotating part 1101, and the first protrusion piece 113 is
arranged on the rotating part 1101. Therefore, when bending the
side covers of different specifications, it is not necessary to
disassemble the entire rotating rods, but only to replace the rod
parts. The first protrusion pieces 113 are located on the rotating
parts 1101, and the first protrusion pieces 113 protrude to middle
of the two rotating rods 11.
[0042] In order to further improve the success rate of hooking, as
a preferred embodiment, as shown in FIGS. 4 and 5, the two rotating
rods 11 are respectively provided with a second protrusion piece
114, wherein one of the second protrusion pieces 114 is provided on
one of the rotating rods 11 and protrudes towards the other
rotating rod 11, and protruding heights of the second protrusion
pieces 114 are less than protruding heights of the bending pieces
12, that is, the second protrusion pieces 114 are connected with
one ends of the rotating rods 11 that away from the first driving
member 112 and protrude to the middle of the two rotating rods 11.
By the cooperation of the second protrusion pieces 114 and the
bending pieces 12, when the two rotating rods 11 move towards each
other, when the bending pieces 12 bend the side covers 1011 to the
preset position, the second protrusion pieces 114 come into contact
with a box body and press the box body to deform, and the slightly
deformed box body makes the hooking of the side covers simpler, and
the box sealing device of the present embodiment is used for the
bending and hooking of the side covers, and is simple in structure
and high in success rate.
[0043] Preferably, as shown in FIG. 5, the rotating rods 11 are
provided with first guide rails 115; the bending pieces 12 are
capable of moving along the first guide rails 115 to be close to or
away from the second protrusion pieces 114. Since the distance
between the optimum positions of the different side covers 1011 to
bear applied force and the stressed position of the box body are
different, the distance between the bending piece 12 and the second
protrusion piece 114 can be adjusted to meet the requirements of
the packing box of the different size or shapes for bending the
side covers. Preferably, the first guide rails 115 are sliding
groove formed in the rotating rods 11, the bending pieces 12 are
clamped in the sliding grooves so as to move along the sliding
grooves, and when moving to preset positions, the bending pieces 12
and the rotating rods 11 can be fixed to each other by means of
bolts or snaps, etc. It should be noted herein that the first guide
rails 115 are not limited to the above-mentioned structure, and the
guide rails may adopt structures such as a slide bar or a slideway
protruding from the rotating rod 11 and then be positioned in
cooperation with the bolts or the snaps. For example, the bending
pieces 12 are connected with the rotating rods 11 by means of
slidable snaps, so that an effective adjustment of the distance
between each bending piece 12 and the corresponding second
protrusion piece 114 can be achieved.
[0044] In order to improve the success rate of hooking, as shown in
FIG. 6, as a preferred embodiment, the box sealing device 1 further
comprises a hooking mechanism 13 provided between the two rotating
rods 11, wherein the hooking mechanism 13 comprises a second
driving member 131 and a rotating plate 132, the second driving
member 131 is detachably connected with the mounting bracket 111,
the rotating plate 132 is fixed to the second driving member 131 to
rotate with the second driving member 131, and the two rotating
rods 11 are located on two sides of the rotating plate 132. The
second driving member 131 in this embodiment selects a rotating
cylinder. According to the box sealing device 1, by means of the
hooking mechanism 13, while the side covers 1011 are bent, the
rotating plate 132 is inserted between the two side covers 1011,
and the second driving member 131 drives the rotating plate 132 to
rotate 180.degree., the hooking of the side covers 1011 is realized
and the hooking tongues 1016 of the side covers 1011 are completely
hooked, the device is simple in structure and has a high success
rate of complete hooking of the side covers 1011.
[0045] Preferably, as shown in FIG. 7, the bending pieces 12
further comprise extension parts 124, one ends of the bending piece
bodies 123 are connected with the rotating rods 11, the other ends
of the bending piece bodies 123 are connected with the extension
parts 124, and the extension parts 124 of the two bending pieces 12
are arranged in a staggered manner. One ends of the bending piece
bodies 123 are connected with the rotating rods 11 via the fixing
parts 121, the other ends of the bending piece bodies 123 are
connected with the extension parts 124 via the bending parts 122,
that is, the extension parts 124 are provided at the ends of the
bending parts 122, the extension parts 124 as extension of the
bending parts 122 are arranged in a mutually staggered manner. The
extension parts 124 are inclined relative to the bending piece
bodies 123 in a direction close to the rotating plate 132, so that
a certain included angle can be formed between the two extension
parts 124 after the two rotating rods 11 reach the preset position,
and an included angle can also be formed between the side covers
1011 in contact with the extension parts 124 to facilitate the
subsequent hooking of the side covers 1011. The two extension parts
124 are arranged in a staggered manner so that the two extension
parts 124 do not interfere with each other during operation and the
side covers 1011 can be bent to the preset position. In the present
embodiment, the rotating rods 11 may also be provided with the
first guide rails 115 such that the bending pieces 12 may move
along the first guide rails 115 to be close to or away from the
mounting bracket 111, and the bending pieces 12 may be positioned
at preset positions on the rotating rods 11 to be adapted to the
bending and hooking of side covers 1011 of different
specifications. In the present embodiment, the first guide rails
115 select sliding grooves, the bending pieces 12 are provided with
sliding blocks matched with the sliding grooves, and can be fixed
by means of bolts or the like when moving to preset positions.
[0046] As shown in FIGS. 8 and 9, as a preferred embodiment of the
embodiments mentioned above, pressing pieces 125 are arranged at
one ends of the bending piece bodies 123, the pressing pieces 125
are positioned on one sides of the extension parts 124, the
extension part 124 and the pressing piece 125 on one of the
rotating rod 11 are staggered with the extension part 124 and the
pressing piece 125 on the other rotating rod 11. The pressing piece
125 and the extension part 124 are both provided at the ends of the
bending piece bodies 123 and arranged side by side. Due to the
staggered arrangement of the extension parts 124, the pressing
pieces 125 are arranged in a staggered manner, and the bending
pieces 12 do not interfere with each other when moving toward each
other. That is, the extension part 124 of one of the rotating rods
11 is arranged opposite to the pressing piece 125 of the other
rotating rod 11. The first driving member 112 drives the two
rotating rods 11 to move towards each other, and at the same time,
drives the bending pieces 12 to be close to each other, and the
bending pieces 12 further come into contact with the box body; when
the extension parts 124 bend the side covers 1011, one of the
pressing pieces 125 presses down the side cover 1011 on one side,
and at the same time, the other pressing piece 125 is inserted into
the edge of the side cover 1011 on the other side, thereby further
improving the success rate of hooking the two side covers 1011 and
achieving the hooking of the side covers 1011.

Specifically, the third driving member 118 may select an electric
cylinder, or any other driving member capable of driving the
sectioned positioning movement of the cover bending assembly. The
third driving member 118 drives the rotating rods 11 to move
towards the packing box 101 stage by stage, so that the box sealing
device 1 can bend the side covers 101 stage by stage to be adapted
to the requirements of packing boxes 101 of different sizes for
bending and hooking the side covers 101.
[0048] The box sealing device provided in the first embodiment of
the present application is simple in structure and easy to mount,
and, when being used for product packing, can be used in
combination with an device used in working processes such as box
blank unfolding, packing box grabbing and material grabbing, and
can also be used in combination with assemblies used in other
packing processes of main covers or side covers.
[0049] The second embodiment of the present application further
provides a packing machine comprising the box sealing device 1
described above.
[0050] The third embodiment of the present application further
provides a method for hooking side covers, comprising the following
steps:
