[0002] The paper towel stacking structure can facilitate the stacking of paper towels so that the paper towels can form a paper towel stack for subsequent cutting or packaging. In order to facilitate the effective delivery of paper towels to the above structure, it is often necessary to set a corresponding paper guide roller mechanism, such as the paper towel stacking machine stacking and conveying mechanism described in CN202222929198.4, which discloses a corresponding first paper guide roller group and a second paper guide roller group.

[0022] One end of the optical roller 11 passes through the frame 6 , and the first gear 12 is fixedly sleeved on the end of the optical roller 11 , so that the first gear 12 can rotate with the rotation of the optical roller 11 .

[0023] The conveying roller mechanism 1 also includes a transmission gear 14, which is fixedly mounted on the end of the optical roller 11 extending from the frame. The optical roller 11 can rotate with the rotation of the transmission gear 14. The transmission gear 14 can be used to connect with an external transmission device, so that the external power device can drive the transmission gear 14 to rotate through the external transmission device.

[0024] There can be several embossing roller mechanisms 2. In the present embodiment, there are preferably four embossing roller mechanisms 2, two of which are respectively arranged on the top and left sides of the conveying roller mechanism 1, and the other two embossing roller mechanisms 2 are respectively arranged on the top and right sides of the conveying roller mechanism 1.

[0025] The embossing roller mechanism 2 includes a embossing roller 21, a second gear 22, a second bearing, a spline 23 and a second bearing seat 24. In each embossing roller mechanism 2, there are preferably two second bearings and second bearing seats 24, and through holes 61 are respectively provided on both sides of the frame 6, two on each side, and the two second bearing seats 24 in one embossing roller mechanism 2 are separately and slidably embedded in the two through holes 61 of the frame 6, and the two second bearing seats 24 in another embossing roller mechanism 2 are separately and slidably embedded in the other two through holes 61 of the frame 6.

[0026] In the same embossing roller mechanism 2, the outer rings of the two second bearings are fixedly embedded in the two second bearing seats 24 respectively, and the inner rings of the two second bearings are fixedly sleeved on the embossing roller 21, so that the embossing roller 21 can be rotatably arranged on the frame 6.

[0027] One end of the printing roller 21 passes through the frame 6, and the spline 23 is fixedly sleeved on the end of the printing roller 21. A plurality of protrusions are provided on the side of the spline 23. A slide groove is provided in the second gear 22, and the protrusion is embedded in the slide groove, so that the second gear 22 is sleeved on the spline 23, and the second gear 22 can slide on the spline 23. By sliding the second gear 22 to a corresponding position, the second gear 22 of any printing roller structure 2 can be meshed with the first gear 12 of the optical roller mechanism 1.

[0028] The printing roller mechanism 2 also includes a locking bolt, and a locking hole is provided on the second gear 22. When the position of the second gear 22 reaches the required position, the second gear 22 can be fixed on the spline 23 by locking the locking bolt into the locking hole. At this time, the second gear 22 is effectively fixed and cannot slide on the spline 23.

[0029] The first driving mechanism 3 is preferably four, which are arranged corresponding to the second bearing seats 24 at four different positions in the two printing roller mechanisms 2. Preferably, the first driving mechanism 3 includes a first hydraulic cylinder 31 and a connecting block 32, the cylinder body of the first hydraulic cylinder 31 is fixedly mounted on the frame 6 by bolts, the piston rod of the first hydraulic cylinder 31 and the connecting block 32 are fixedly connected by bolts, and the connecting block 32 and the corresponding second bearing seat 24 are fixedly connected by bolts.

[0030] There are preferably two leveling mechanisms 4 and four second driving mechanisms 5 , wherein two second driving mechanisms 5 are connected to one leveling mechanism 4 , and the other two second driving mechanisms 5 are connected to another leveling mechanism 4 .

[0031] The specific connection between the second driving mechanism 5 and the leveling mechanism 4 is preferably that the leveling mechanism 4 includes a leveling roller 41 and a swing seat 42. One end of the swing seat 42 is hinged on the frame 6 through a pin, so that the swing seat 42 can swing on the frame 6, and the swing seat 42 is sleeved on the leveling roller 41 through a bearing, so that the leveling roller 41 can rotate on the swing seat 42, and the leveling roller 41 can also swing with the swing seat 42.

[0032] The second driving mechanism 5 includes a second cylinder 51 and a hinge block 52. A protrusion is provided at the bottom of the cylinder body of the second cylinder 51, and the protrusion is hinged on the frame 6 through a pin shaft. The second cylinder 51 can swing to a certain extent on the frame 6. The hinge block 52 is fixedly connected to the piston rod of the second cylinder 51, and the other end of the hinge block 52 and the swing seat 42 are hinged through a pin shaft.

[0033] The paper towel printing transmission mechanism also includes a brush roller 7, which can be several brush rollers 7. In the present embodiment, the number of brush rollers 7 is equivalent to the number of printing rollers 21, and preferably four. The four brush rollers 7 are rotatably mounted on the frame 6 through bearings, and the four brush rollers 7 and the printing rollers 21 of the four printing roller mechanisms 2 are in one-to-one correspondence and abutted, so that the brush rollers 7 can realize passive rotation as the printing rollers 21 rotate.

[0034] The tissue printing transmission mechanism further comprises a bending roller 8, and there can be two bending rollers 8, and both bending rollers 8 are rotatably mounted on the frame 6 through an axle seat.

[0035] When the paper towel printing transmission mechanism is in use, different printing patterns can be set on different printing rollers 21, and the transmission gear 14 can be connected to an external transmission device, so that the external power device can drive the transmission gear 14 to rotate through the external transmission device.

[0036] Moreover, relying on the operation of the first hydraulic cylinder 31 of each first driving mechanism 3, the second bearing seat 24 of the corresponding embossing roller mechanism 2 can be driven to move toward the smooth roller 11 of the conveying roller mechanism 1, so that each embossing roller 21 can be close to the smooth roller 11 and leave a certain distance. Then, according to the needs of printing and printing, the corresponding embossing roller 21 is selected, and the second gear 22 connected to the embossing roller 21 is connected to the spline 23 by sliding, so that the second gear 22 of the embossing roller 21 is meshed with the first gear 12 connected to the smooth roller 11, and then the lock bolt is locked so that the second gear 22 of the embossing roller 21 to be used is fixed.

[0037] At the same time, relying on the work of the second cylinder 51 of each second driving mechanism 5, the swing seat 42 of the leveling mechanism 4 can be driven to swing, so that the leveling roller 41 of the leveling mechanism 4 can move toward the smooth roller 11 of the conveying roller mechanism 1, and it can approach the smooth roller 11 and leave a certain distance.

[0038] The paper towels delivered from the outside can bypass the bending roller 8, bypass the smooth roller 11 and the printing roller 21 to be printed, and then bypass the smooth roller 11 and the flattening roller 41 before being sent to the subsequent stacking device. The delivery of the paper towels between the above rollers can be achieved by the external power device driving the smooth roller 11 to rotate through the transmission gear 14.

[0039] The bending roller 8 can conveniently guide and smooth the paper towels outputted from other mechanisms, so that the paper towels outputted from other mechanisms can be effectively transported between the smooth roller 11 and the embossing roller 21 .

[0040] The rotation of the optical roller 11 can mesh with the first gear 12 and the second gear 22, so that the printing roller 21 provided with the required printing also rotates accordingly. When the paper towel passes between the printing roller 21 and the optical roller 11, the printing can be intermittently printed with the rotation of the printing roller 21, and the first driving mechanism 3 can provide corresponding pressure for the printing.

[0041] The flattening mechanism 4 can make the paper towel fit better on the conveying roller mechanism 1, reduce the wrinkles on the conveying roller mechanism 1 and affect the printing effect, and facilitate the paper towel to be more smoothly conveyed to the subsequent folding device.

[0042] At the same time, when the embossing roller 21 rotates, the brush roller 7 abutting against it can passively rotate accordingly. The brush roller 7 can remove the paper scraps remaining on the surface of the embossing roller 21 during the embossing process, thereby reducing the interference of the above paper scraps on the printing.

[0043] In addition, if the printed print needs to be replaced, the second gear 22 connected to the original print roller 21 can be loosened to make the second gear 22 movable again, and the second gear 22 can be slid to separate the meshing of the second gear 22 and the first gear 12. Then the second gear 22 connected to the print roller 21 corresponding to the new print is slid to mesh the new second gear 22 with the first gear 12 connected to the optical roller 11. After it is in place, the lock bolt is locked on the second gear 22 of the new print roller 21 to fix the position of the new second gear 22.

[0044] The smooth roller 11 can be rotated synchronously with the new printing roller 21, and the paper towel delivered from the bending roller 8 is changed to bypass between the smooth roller 11 and the new printing roller 21 that needs to be printed, and then bypass between the smooth roller 11 and the leveling roller 41 before being delivered to the subsequent stacking device. The delivery of the paper towel between the above rollers can be achieved by relying on an external power device to drive the smooth roller 11 to rotate, that is, the rapid switching of the printing to be printed on the paper towel can be effectively achieved.

[0045] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
