At the same time, the driving mechanism drives the paper roll shaft to rotate around the axis of the paper roll shaft, so that the part of the paper roll shaft which has not formed local prick corresponds to the sharp parts of the pressure head. The upper die seat continues to close to drive the sharp parts of the pressure head to abut against the part which has not formed local prick to press out local prick, and then the upper die seat continues to open to drive the sharp parts of the pressure head to go up. At the same time, the driving mechanism continues to drive the paper roll shaft to rotate around the axis of the paper roll shaft, so that the part of the paper roll shaft which has not formed local prick corresponds to the sharp parts of the pressure head. The closing and opening actions are repeated to drive the driving mechanism to drive the paper roll shaft to rotate around the axis of the paper roll shaft, so that the continuous global prick is formed on the outer periphery of the paper roll shaft.

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0015] This embodiment provides a method for processing paper roll embossing, and relates to a processing mold for paper roll embossing, such as... Figure 1 As shown, the mold includes an upper mold base 1, a pressure head 3, a lower mold base 2 and a driving mechanism. The pressure head 3 is disposed on the upper mold base 1, and the lower end of the pressure head 3 is provided with several spikes 31. The lower mold base 2 is provided with a positioning block 4. The driving mechanism is disposed on one side of the lower mold base 2 and corresponds to the position of the positioning block 4. The driving mechanism is provided with a clamping part. The processing method is as follows: Place one end of the paper roll 5 on the positioning block 4 and the other end on the gripping part of the drive mechanism. When the operation switch of the processing mold is turned on, the upper mold base 1 closes and drives the tip 31 of the pressure head 3 to press against the paper roll shaft 5 to create partial burrs 6. Then the upper mold base 1 opens and drives the tip 31 of the pressure head 3 to move upward. At the same time, the drive mechanism drives the paper roll shaft 5 to rotate around its own axis, so that the part of the paper roll shaft 5 that has not formed partial burrs 6 corresponds to the tip 31 of the pressure head 3. The upper mold base 1 continues to close the mold, causing the spiked part 31 of the pressure head 3 to press out the partial 6 without forming the partial 6. Then the upper mold base 1 continues to open the mold, causing the spiked part 31 of the pressure head 3 to move upward. At the same time, the drive mechanism continues to drive the paper roll 5 to rotate around its own axis, so that the part of the paper roll 5 without forming the partial 6 corresponds to the spiked part 31 of the pressure head 3. The repeated mold closing and opening actions, combined with the drive mechanism, drive the paper roll 5 to rotate around its own axis, so that a continuous global burr pattern 6 is formed on the outer periphery of the paper roll 5.
[0016] In this embodiment, continuous global perforations 6 are pressed onto the surface of the paper roll 5, which greatly increases the friction and gripping force between the paper roll 5 and the paper. This effectively avoids paper jamming and slippage during transport, ensuring smooth printing and improving print quality. Furthermore, by repeatedly closing and opening the mold in conjunction with the rotation of the paper roll 5 around its own axis, uniform and regular global perforations 6 can be formed on the outer circumference of the paper roll 5. This ensures that the frictional force is evenly distributed across all parts of the paper roll 5, avoiding uneven paper transport caused by excessive or insufficient local friction.
[0017] like Figure 2 and Figure 3As shown, in this embodiment, the spikes 31 are triangular pyramidal in shape, capable of pressing out three-dimensional burrs 6 onto the surface of the paper roll 5 to ensure sufficient friction. Multiple spikes 31 are arranged in an alternating pattern and facing different directions, providing friction in multiple directions when the paper roll 5 contacts the paper, effectively preventing slippage. Of course, in other embodiments, the shape, number, and arrangement of the spikes 31 can be customized according to actual needs.
[0018] like Figure 1 As shown, this embodiment uses two pressure heads 3, with their positions corresponding to the two ends of the paper roll 5, ensuring that both ends of the paper roll 5 can form perforations 6. This guarantees stable paper feeding and improves subsequent printing results. Of course, the number and position of the pressure heads 3 can be adjusted according to actual needs to create perforations 6 at different positions on the paper roll 5.
[0019] like Figure 1 As shown, this embodiment also includes a rotating chuck 8. The output end of the drive mechanism is horizontally arranged. The rotating chuck 8 is arranged at the output end of the drive mechanism to form the gripping part, which is used to grip the other end of the paper roll 5 and drive the paper roll 5 to rotate around its own axis.
[0020] This embodiment uses a drive mechanism and a rotating chuck 8 to automatically drive the paper roll 5 to rotate around its own axis, reducing manual intervention and labor intensity. It also avoids processing errors caused by inaccurate or unstable manual operation, improving the automation and stability of the processing. The drive mechanism can precisely control the rotation angle and speed of the rotating chuck 8. Appropriate rotation parameters can be set according to different processing requirements to ensure that the paper roll 5 accurately rotates to the predetermined position each time the mold is closed, thereby achieving precise processing of the embroidery 6. Since the rotating chuck 8 can grip one end of the paper roll 5, only one positioning block 4 is needed in this embodiment for positioning the other end of the paper roll 5. Specifically, the positioning block 4 can achieve positioning by opening a positioning groove 41 that matches the size of the paper roll 5, such as... Figure 4 As shown, the structure is simple.
[0021] like Figure 1 As shown, this embodiment also includes an indexing plate 9 and a control unit (not shown in the figure). The indexing plate 9 is located at the output end of the drive mechanism, the rotating chuck 8 is located on the indexing plate 9, and the control unit is communicatively connected to the drive mechanism.
[0022] The index plate 9 has high-precision indexing function, which can accurately position the paper roll shaft 5 at each processing position according to a preset angle. During the process of the paper roll shaft 5 being perforated by the perforator 6, after each perforation operation is completed, the index plate 9 will rotate the paper roll shaft 5 to the next accurate angle position according to the instruction of the control unit, ensuring the accuracy of each perforation position. For example, the index plate 9 can rotate the paper roll shaft 5 by 36° each time, and the upper die holder 1 and the lower die holder 2 will perform 10 times of die closing and opening operation, so that a continuous and uniform global perforation 6 can be formed on the outer periphery of the paper roll shaft 5, and the angle interval between each perforation 6 is strictly consistent, which greatly improves the distribution precision of the perforations 6 on the outer periphery of the paper roll shaft 5, and ensures that the paper roll shaft 5 can smoothly convey paper.
[0023] Further, the driving mechanism of the embodiment is a servo motor 7, but is not limited thereto, and is simple in structure and easy to set up, and other motors can also be used in other embodiments.
[0024] The orientation terms mentioned in the present specification are defined with respect to the structure shown in the drawings, and are relative concepts, so it is possible to change accordingly according to different positions and different use states. Therefore, these or other orientation terms should not be interpreted as limiting terms.
[0025] The above description is only the preferred embodiment of the present application, and is not a limitation on the design of the present application. Any equivalent changes made according to the key design of the present application shall fall within the scope of protection of the present application.
