conventional cutting structure of a paper towel comprises two wall
plates 90 between which a roll 91, a press plate 92, a power wheel
93, and a blade wheel 94 are mounted. The paper is passed between
the downward pressed press plate 92 and the roll 91, and is pulled
downward by the power wheel 93 and the roll 91. The power wheel 93
may drive the roll 91 and the blade wheel 94 simultaneously. When
the blade wheel 94 is rotated, the blade 95 of the blade wheel 94
contacts the chopping board 06, thereby cutting the passing
paper.
[0005] However, the blade 95 of the blade wheel 94 contacts the
chopping board 06 frequently, so that the blade 95 of the blade
wheel 94 is easily worn out during long-term utilization, and the
cutting effect is greatly affected, thereby causing a large load in
maintenance, and causing inconvenience to the user. In addition,
the conventional cutting structure of a paper towel has a
complicated construction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0027] Referring to the drawings and initially to FIG. 2, a
separation device of a paper towel in accordance with a first
embodiment of the present invention is shown. The paper towel 4
used in the separation device is a continuous paper made of a
material such as the natural fiber, artificial fiber, synthetic
fiber and the like. The paper towel 4 may have a roll-shape or a
foldable shape. The paper towel 4 is provided with multiple sensing
marks 42 that may be in the form of a cutout, or may be formed on
the paper towel 4 in a printing or bonding manner. The paper towel
4 may be provided with a easily detachable line 41, so that the
paper towel 4 may be separated easily and smoothly. In addition,
when the paper towel 4 is made of a material such as artificial
fiber, synthetic fiber and the like, each of the two sides of the
easily detachable line 41 is formed with a press portion 43 in a
heat melted manner, thereby preventing from detachment of the fiber
when the paper towel is cut.
[0028] The separation device comprises a housing 3, a first roll
set 1, and a second roll set 2. The paper towel 4 may pass through
the first roll set 1 and the second roll set 2 respectively.
[0029] The housing 3 may construct the housing wall of the entire
separation device, and has at least two wall plates 31 between
which the first roll set 1 and the second roll set 2 are pivotally
mounted. The housing 3 is provided with a detection member 32 that
may be a conventional light control detection member. When the
sensing mark 42 of the paper towel 4 passes through the detection
member 32, the detection member 32 may detect passage of the
sensing mark 42 of the paper towel 4, and may send a signal, so
that the paper towel 4 may enter the first roll set 1 and the
second roll set 2 easily. A guide board 33 is mounted between the
two wall plates 31, and is located above the first roll set 1 and
the second roll set 2. The housing 3 may be provided with a
conventional liquid spray tube 34 to wet the passing paper towel 4,
and a guide plate 35 to guide the paper towel 4 outward.
[0030] The first roll set 1 consists of at least two rolls 11 and
12 each having two ends respectively pivoted on the wall plates 31.
The roll faces of the two rolls 11 and 12 contact with each other
or almost contact with each other. The two rolls 11 and 12 of the
first roll set 1 may be rotated relative to each other by driving
of drive members 13, such as gears, so that the paper towel 4 may
pass between the two rolls 11 and 12, and may be pulled downward to
the second roll set 2. The two rolls 11 and 12 of the first roll
set 1 may be driven to rotate by a power member 14.
[0031] The second roll set 2 is located at the lower side or the
rear side of the first roll set 1, and consists of at least two
rolls 21 and 22 each having two ends respectively pivoted on the
wall plates 31. The roll faces of the two rolls 21 and 22 contact
with each other or almost contact with each other. The two rolls 21
and 22 of the second roll set 2 may be rotated relative to each
other by driving of drive members 23, such as gears, so that the
paper towel 4 may pass between the two rolls 21 and 22, and may be
pulled downward. The two rolls 21 and 22 of the second roll set 2
may be driven to rotate by a power member 24.
[0032] Referring to FIGS. 3 and 4, one end of the paper towel 4 is
guided to pass through the two rolls 11 and 12 of the first roll
set 1 and pass through the two rolls 21 and 22 of the second roll
set 2, and may be pulled downward by rotation of the first roll set
I and the second roll set 2. At this time, the first roll set 1 and
the second roll set 2 may be rotated at an equal speed. When the
sensing mark 42 of the paper towel 4 passes through the detection
member 32, the detection member 32 may detect passage of the
sensing mark 42 of the paper towel 4, and may send a signal, so
that power member 14 of the first roll set 1 may stop operation or
reduce its velocity. Thus, a pulled force is applied on the paper
towel 4 between the first roll set 1 and the second roll set 2, so
that the paper towel 4 may be separated from the easily detachable
line 41 (see FIG. 5), and the separated paper towel 4 may be pulled
downward by the two rolls 21 and 22 of the second roll set 2, to be
guide outward by the guide plate 35.
[0033] Referring to FIG. 6, a separation device of a paper towel in
accordance with a second embodiment of the present invention is
shown.
[0034] The housing 3 is provided with a clutch wheel 36 whose
movement may be controlled by a controller 37 such as an
electromagnetic valve. When the sensing mark 42 of the paper towel
4 passes through the detection member 32, the detection member 32
may detect passage of the sensing mark 42 of the paper towel 4, and
may send a signal, so that the clutch wheel 36 may detach from the
drive members 13 and 23 of the first roll set 1 and the second roll
set 2, and may mesh with the drive members 13 and 23 of the first
roll set I and the second roll set 2 again after a predetermined
period of time.
[0035] The first roll set 1 is not provided with a power member,
while the second roll set 2 has a power member 24. Thus, when the
clutch wheel 36 meshes with the drive members 13 arid 23 of the
first roll set 1 and the second roll set 2 as shown in FIG. 7, the
rolls 11, 12, 21 and 22 of the first roll set 1 and the second roll
set 2 may be rotated at an equal speed, and the paper towel 4 may
be pulled downward. When the clutch wheel 36 detaches from the
drive members 13 and 23 of the first roll set 1 or the second roll
set 2 as shown in FIG. 8, the rolls 11 and 12 of the first roll set
1 may stop rotating. Thus, a pulled force is applied on the paper
towel 4 between the first roll set 1 and the second roll set 2, so
that the paper towel 4 may be separated from the easily detachable
line 41.
[0036] Referring to FIG. 9, a separation device of a paper towel in
accordance with a third embodiment of the present invention is
shown. The paper towel 4 used in the separation device is a
continuous paper made of a material such as the natural fiber,
artificial fiber, synthetic fiber and the like. The paper towel 4
may have a roll-shape or a foldable shape. The paper towel 4 is
also provided with multiple sensing marks 42 that may be in the
form of a cutout, or may be formed on the paper towel 4 in a
printing or bonding manner. The paper towel 4 may be provided with
a easily detachable line 4 1, so that the paper towel 4 may be
separated easily and smoothly. In addition, when the paper towel 4
is made of a material such as artificial fiber, synthetic fiber and
the like, each of the two sides of the easily detachable line 41 is
formed with a press portion 43 in a heat melted manner, thereby
preventing from detachment of the fiber when the paper towel is
cut. Further, the easily detachable line 41 in the preferred
embodiment may be constructed by holes of different lengths,
including at least one elongated hole 411 which is larger than
other holes 412 on the easily detachable line 41.
[0037] The first roll set 1 consists of at least two rolls 11 and
12. The roll faces of the two rolls 11 and 12 of the first roll set
1 contact with each other or almost contact with each other. The
two rolls 11 and 12 of the first roll set 1 may be rotated relative
to each other by driving of drive members, such as gears, so that
the paper towel 4 may pass between the two rolls 11 and 12, and may
be pulled downward to the second roll set 2.
[0038] Referring to FIGS. 10 and 11, the second roll set 2 is
located at the lower side or the rear side of the first roll set 1,
and consists of two rolls 21 and 22. The two rolls 21 and 22 of the
second roll set 2 may be rotated relative to each other by driving
of drive members, such as gears, so that the paper towel 4 may pass
between the two rolls 21 and 22, and may be pulled downward. Each
of the roll faces of the two rolls 21 and 22 may form a non-single
line. In the preferred embodiment, each of the roll faces of the
two rolls 21 and 22 may form an arcuate face which has a mediate
section having an arcuate convex portion 211 and 221. The arcuate
convex portions 211 and 221 of the two rolls 21 and 22 contact with
each other or almost contact with each other. Thus, the roll faces
of the two rolls 21 and 22 only have smaller contact faces, and the
contacting arcuate convex portions 211 and 221 of the two rolls 21
and 22 are aligned with the elongated hole 411 of the paper towel
4. Thus, when a rotation speed difference is produced between the
first roll set 1 and the second roll set 2, the motor may provide a
smaller drive torque to tear the paper towel 4 between the first
roll set 1 and the second roll set 2 as shown in FIG. 12.
[0039] Referring to FIG. 13, the second roll set 2 of a separation
device of a paper towel in accordance with a fourth embodiment of
the present invention is shown. The second roll set 2 consists of
two rolls 21 and 22. Each of the roll faces of the two rolls 21 and
22 may form a non-single line. In the preferred embodiment, each of
the roll faces of the two rolls 21 and 22 has a mediate section
formed with an equal-diameter portion 212 and 222 having a larger
diameter. Each of the equal-diameter portions 212 and 222 has two
sides each having an oblique shoulder portion 213 and 223. Thus,
the roll faces of the two rolls 21 and 22 only have smaller contact
faces, and the contacting equal-diameter portions 212 and 222 of
the two rolls 21 and 22 are aligned with the elongated hole 411 of
the paper towel 4 (see FIG. 14). Preferably, the length of the
contacting equal-diameter portions 212 and 222 of the two rolls 21
and 22 is smaller than that of the elongated hole 411 of the paper
towel 4. Thus, when a rotation speed difference is produced between
the first roll set 1 and the second roll set 2, the motor may
provide a smaller drive torque to tear the paper towel 4 between
the first roll set 1 and the second roll set 2.
[0040] Referring to FIG. 15, the second roll set 2 of a separation
device of a paper towel in accordance with a fifth embodiment of
the present invention is shown. The second roll set 2 consists of
two rolls 21 and 22. Each of the roll faces of the two rolls 21 and
22 may form a non-single line. In the preferred embodiment, each of
the roll faces of the two rolls 21 and 22 is formed with a
corrugated shape, thereby forming multiple convex portions 214 and
224 and multiple concave portions 215 and 225 between the multiple
convex portions 214 and 224. Thus, the roll faces of the two rolls
21 and 22 only have smaller contact faces, and the contacting
convex portions 214 and 224 of the two rolls 21 and 22 are aligned
with the elongated hole 411 of the paper towel 4 (see FIG. 16).
Thus, when a rotation speed difference is produced between the
first roll set 1 and the second roll set 2, the motor may provide a
smaller drive torque to tear the paper towel 4 between the first
roll set 1 and the second roll set 2.
[0041] Accordingly, the separation device of a paper towel in
accordance with the present invention needs not to provide a
cutting blade set, thereby simplifying the construction, and
facilitating production and assembly. In addition, the separation
device of a paper towel in accordance with the present invention
does not have the problem of wear of the cutting blade, thereby
facilitating maintenance. Further, the supply length of the paper
towel may be set during fabrication. In comparison, in the
conventional separation device of a paper towel, the tooth number
of the gear and the rotation speed of the motor need to be changed
when the supply length of the paper towel needs to be changed.
Further, the roll faces of the two rolls of the second roll set
only have smaller contact faces, and the contacting faces of the
two rolls of the second roll set are aligned with the elongated
hole of the paper towel, so that the paper towel between the first
roll set and the second roll set may be torn out easily, and the
motor for driving the first roll set and the second roll set may
provide a smaller drive torque to tear the paper towel between the
first roll set and the second roll set, thereby reducing loss of
power.
[0042] Although the invention has been explained in relation to its
preferred embodiment as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
