DETAILED DESCRIPTION OF THE INVENTION
[0022] In accordance with a preferred embodiment of the present
invention, the present invention provides a machine for
manufacturing air pillows from plastic bags, comprising a frame, a
conveyor mechanism, and an air inflating mechanism.
[0023] FIGS. 1 to 3 depict the machine as a presently embodiment,
wherein machine comprises a frame, a conveyor mechanism, and an air
inflating mechanism.
[0024] The frame 10 comprises a front wall 11, a rear wall 12, a
top wall 13, a bottom wall 14, and two sidewalls 15 and 16, wherein
one of the sidewalls 15 is an operative sidewall. The frame 10 is
formed a compact housing that the frame 10 is portable. The frame
10 further has a compartment 17 defined within the front wall 11,
the rear wall 12, the top wall 13, the bottom wall 14, and the
sidewalls 15 and 16.
[0025] The conveyor mechanism 17 comprises a motor 18, a first
conveyor means 19, and a second conveyor means 20. The motor 18 is
supported within the compartment 17 by the sidewall 15. The first
conveyor means 19 is linked to the motor 18 and is supported by the
sidewall 15 within the compartment 17. The second conveyor means 20
is driven by said first conveyor means and supported at the
sidewall 15 of the frame 10 out of the compartment 17. The second
conveyor means 20 will guide and convey the plastic bags in a
feeding direction. The second conveyor means 20 further has a
conveying clearance 21 for fitting said plastic bag when the
plastic bags are conveyed by the second conveyor means 20. The
plastic bags are guided to feed at the conveying clearance 21 in
the feeding direction.
[0026] The air inflating mechanism 22 comprises a sealing unit 23
for sealing an opening of the plastic bag and an air needle 24
protruded from the sidewall 15 of the frame 10 for inflating the
plastic bag before the opening of the plastic bag is sealed. When
the plastic bags are fed at the conveying clearance 21, the air
needle 24 injects air into each of the plastic bags. When the
plastic bag is inflated, the opening of the plastic bag is sealed
by the sealing unit 23.
[0027] In FIGS. 1 and 2, the second conveyor means 20 comprises two
second upper conveyor rollers 25 and two second lower conveyor
rollers 26. The second upper conveyor rollers 25 and the second
lower conveyor rollers 26 are made of frictional material such as
rubber. Therefore, when they are driven to rotate, the plastic bags
are frictionally fed via the second upper conveyor rollers 25 and
the second lower conveyor rollers 26 in the feeding direction. The
conveying clearance 21 is formed between the upper conveyor rollers
25 and the second lower conveyor rollers 26. The upper conveyor
rollers 25 are aligned with the second lower conveyor rollers 26 in
a vertical direction.
[0028] In FIG. 1, the machine further comprises a plastic bag
rolling arm 27 coupled with at the front wall 11 of the frame 10
for holding a roll of the plastic bags to be fed to the conveying
clearance 21. The roll of plastic bags is supported by the plastic
bag rolling arm 27, wherein the plastic bag is fed at the conveying
clearance 21. Therefore, when the plastic bags are fed at the
conveying clearance 21 via the upper conveyor rollers 25 and the
second lower conveyor rollers 26, the roll of the plastic bags are
unrolled at the plastic bag roller arm 27.
[0029] The sealing unit 23 comprises an upper sealer 28 and a lower
sealer 29 forming a sealing clearance 30 between the upper sealer
28 and the lower sealer 29, wherein the sealing clearance 30 is
aligned with the conveying clearance 21 of the second conveyor
means 20 in the same planar direction. The plastic bag is fed at
the sealing clearance 30 before the conveying clearance 21.
[0030] The air needle 24 is extended between the sealing clearance
30. The air needle 24 is also extended at the same direction of the
conveying clearance 21 of the second conveyor means 20. The sealing
clearance 30 is located between the air needle 24 and the conveying
clearance 21, so that the plastic bag will be inflated by the air
needle 24 before the opening of the plastic bag is sealed.
[0031] In FIG. 3, the air inflating mechanism 22 further comprises
an air pressure adjustable means 31 for adjusting an air pressure
of the plastic bag. The plastic bag is controllable to be inflated
with a predetermined air pressure. The air inflating mechanism 22
further comprises an air blower 32 supported in the compartment 17
and connected to the air needle 25 by an air tube 33.
[0032] In FIGS. 5 and 6, the first conveyor means 19 comprises a
first upper conveyor 34 and a first lower conveyor 35 linked to the
motor 18, and a first transmission gear 36 linked between the first
upper conveyor 34 and the lower conveyor 35.
[0033] The first upper conveyor 34 comprises two first upper
conveyor gears 37 and a first upper convey belt 38 linked between
the two upper conveyor gears 37. An outer upper wall 39 and an
inner upper wall 40 are provided. The outer upper wall 39 is
coupled at the sidewall 15 of the frame 10. The two first upper
conveyor gears 37 are spaced apart and are supported by the inner
upper wall 40. The first transmission gear 36 is supported between
the outer upper wall 39 and the inner upper wall 40. Therefore, the
inner upper wall 40 is positioned between the first upper conveyor
gears 37 and the first transmission gear 36.
[0034] The motor 18 is supported by the first lower conveyor 35 and
is located under the first lower conveyor 35. The first lower
conveyor 35 comprises two first lower conveyor gears 41 and a first
lower convey belt 42 linked between the two lower conveyor gears
41. A second transmission gear 43 linked between the first upper
conveyor 35 and the lower conveyor 35. The first transmission gear
36 is meshed with the second transmission gear 43. An outer lower
wall 44 and an inner lower wall 45 are provided. The outer lower
wall 44 is coupled at the sidewall 15 of the frame 10 and is
positioned below the outer upper wall 39. The two first lower
conveyor gears 41 are supported by the inner lower wall 45. The
second transmission gear 43 is supported between the outer lower
wall 44 and the inner lower wall 45. Therefore, the inner lower
wall 45 is positioned between the second transmission gear 43 and
the first lower conveyor gears 41.
[0035] The two second upper conveyor rollers 25 are coaxial with
the two first upper conveyor gears 37 respectively. The two second
lower conveyor rollers 26 are coaxial with the two first lower
conveyor gears 41 respectively.
[0036] The two second upper conveyor rollers 25 are respectively
driven to rotate by the two first upper conveyor gears 37 and two
second lower conveyor rollers 26 are respectively driven to rotate
by the two first lower conveyor gears 41.
[0037] Four driving axles 46 are extended from the compartment 17
of the frame 10 to an exterior thereof through the sidewall 15. The
two second upper conveyor rollers 25 are connected to the two first
upper conveyor gears 37 by two of the driving axles 46
respectively. The two second lower conveyor rollers 26 are
connected to the two first lower conveyor gears 41 by another two
of the driving axles 46 respectively. The second upper conveyor
rollers 25 and the second lower conveyor rollers 26 are larger than
the first upper conveyor gears 37 and the first lower conveyor
gears 41 in diameter.
[0038] When meshing the first transmission gear 36 with the second
transmission gear 43, the conveying speed of the first conveyor
means 19 is the same as the conveying speed of the second conveyor
means 20. Therefore, the feeding speed of the plastic bag will be
constant and stable to prevent the plastic bag to be jammed at the
conveying clearance 21.
[0039] During operation, the motor 18 will generate a rotational
power to drive the second transmission gear 43 to rotate. The first
transmission gear 36 will be driven to rotate by the second
transmission gear 43. Through the rotational movements of the first
transmission gear 36 and the second transmission gear 43, the two
first lower conveyor gears 41 are concurrently rotated by the first
lower convey belt 42 and the two first lower conveyor gears 41 are
concurrently rotated by the first lower convey belt 42. The
rotational speeds of the first lower conveyor gears 41 will be the
same which are the same as the rotational speeds of the first lower
conveyor gears 41. Therefore, the second upper conveyor rollers 25
and the second lower conveyor rollers 26 are concurrently driven to
rotate to convey the plastic bag at a stable and constant
speed.
[0040] While the embodiments and alternatives of the invention have
been shown and described, it will be apparent to one skilled in the
art that various other changes and modifications can be made
without departing from the spirit and scope of the invention.
