Description

Technical Field

[0001] This application relates to the field of die-cutting machine equipment, and in particular to a lifting rod device for a die-cutting machine. Background Technology

[0002] A die-cutting machine is an industrial device that uses a die to cut, crimp, or shape non-metallic materials (sheets or strips). It is widely used in industries such as packaging, printing, and electronics.

[0003] During the die-cutting process, due to the continuity of the strip and the fact that the winding machine is intermittently pulling the strip, the strip will continue to move forward a short distance due to the inertia of the winding process when the winding machine stops intermittently. This causes the die-cutting position of the strip to shift, affecting the die-cutting quality and making the strip inconvenient to use later. Utility Model Content

[0004] To address the issue of strip shifting during conveying due to inertia, this application provides a lifting rod device for a die-cutting machine.

[0005] The lifting lever device for a die-cutting machine provided in this application adopts the following technical solution:

[0006] A lifting device for a die-cutting machine includes a processing table on which a die-cutting machine is mounted. An unwinding machine is located at the feed end of the die-cutting machine, and a winding machine is located at the output end. Strip material slides between the upper and lower die bases of the die-cutting machine. Pressure rollers and a clamping assembly are arranged on the processing table. The pressure rollers are located on both sides of the die-cutting machine. When the winding machine winds the strip material, a gap exists between the pressure rollers and the strip material. When the winding machine pauses winding the strip material, the clamping assembly drives the pressure rollers to press the edge of the strip material against the processing table.

[0007] By adopting the above technical solution, since the strip is intermittently conveyed during continuous operation of the die-cutting machine, when the winding machine collects the strip, there is a gap between the pressure roller and the strip, and the strip is normally wound. When the winding machine stops winding the strip, the upper die holder of the die-cutting machine closes onto the lower die holder. At this time, the pressing component drives the pressure roller to press against the edge of the strip, so that the strip between the upper die holder and the lower die holder of the die-cutting machine cannot slip, thereby improving the die-cutting quality of the strip.

[0008] Optionally, the clamping assembly includes a vertical plate mounted on the processing table, a clamping frame rotatably mounted on the vertical plate, the clamping frame being located above the strip, a counterweight rod being mounted on the side of the clamping frame closer to the die-cutting machine, and a mounting shaft being mounted on the side of the clamping frame away from the die-cutting machine. The pressure roller is mounted on the mounting shaft, and the rotation center of the clamping frame is located between the counterweight rod and the mounting shaft. Under the gravity of the counterweight rod, there is a gap between the pressure roller and the strip. A driving component is mounted on the processing table, and the driving component is used to drive the pressure roller to clamp the edge of the strip.

[0009] By adopting the above technical solution, when the upper and lower die holders of the die-cutting machine are not closed, the counterweight rod, the mounting shaft, and the pressure roller cause uneven mass distribution on both sides of the center of rotation of the pressing frame along the conveying direction of the strip. Therefore, during the normal conveying of the strip, the weight of the counterweight rod causes the pressure roller to separate from the edge of the upper surface of the strip.

[0010] Optionally, the driving component includes a mounting block disposed on the upper die base of the die-cutting machine, a vertically oriented driving rod arranged on the mounting block, a pressure block disposed on the side of the clamping frame near the die-cutting machine, a portal frame disposed on the processing table, and a transmission rod rotatably disposed on the portal frame, one end of the transmission rod being located directly below the driving rod, and the other end being located directly below the pressure block. When the upper die base of the die-cutting machine is separated from the lower die base of the die-cutting machine, the transmission rod abuts against the bottom end of the driving rod, and at the same time, there is a gap between the pressure roller and the strip. When the upper die base of the die-cutting machine is closed with the lower die base of the die-cutting machine, the pressure roller presses against the edge of the strip.

[0011] By adopting the above technical solution, when the upper die seat of the die-cutting machine is closed with the lower die seat, the drive rod will abut against one end of the transmission rod, the transmission rod will rotate, and the other end of the transmission rod will abut against and push the pressure block. The pressure block drives the clamping frame to rotate, and the clamping frame drives the pressure roller to rotate synchronously through the mounting shaft, so that the pressure roller is pressed against the edge of the strip, thereby preventing the strip between the upper die seat and the lower die seat of the die-cutting machine from slipping.

[0012] Optionally, transition wheels are rotatably provided at both ends of the transmission rod. The transition wheel at one end of the transmission rod is used to abut against the end of the drive rod and roll in cooperation with the circumferential surface of the drive rod, while the transition wheel at the other end is used to abut against the lower surface of the pressure block and roll in cooperation.

[0013] By adopting the above technical solution, during the process of the drive rod abutting the transition wheel, the transmission rod will rotate at a certain angle. At this time, the pressure block drives the clamping frame to rotate to the maximum angle, that is, the edge of the strip has been clamped. However, the upper die base of the die-cutting machine will continue to descend. At this time, the circumferential surface of the drive rod will abut against the transition wheel, but the transmission rod will no longer rotate, thereby reducing the possibility of the strip and the transmission rod being crushed.

[0014] Optionally, the drive rod is threaded onto the mounting block, and a lock nut is threaded onto the drive rod to abut against the mounting block.

[0015] By adopting the above technical solution, workers can adjust the distance between the drive rod and the end of the transmission rod by turning the drive rod and the anti-loosening nut, so that the transmission rod can transmit normally and ultimately the pressure roller can press the edge of the strip.

[0016] Optionally, an end plate is provided on the top of the upright plate, and an anti-locking spring is provided between the side of the clamping frame near the die-cutting machine and the end plate.

[0017] By adopting the above technical solution, when the rotation center of the clamping frame cannot rotate and reset normally due to large friction, the elastic force of the anti-locking spring can make the clamping frame rotate, thereby maintaining a distance between the pressure roller and the strip.

[0018] Optionally, the clamping assembly includes a horizontal screw and a guide rod disposed on the upper die base of the die-cutting machine. The axis of the guide rod is parallel to the axis of the horizontal screw. A sliding plate is slidably mounted on both the horizontal screw and the guide rod. Positioning nuts are threaded to both sides of the sliding plate along the axis of the horizontal screw. A clamping column is vertically slidably mounted on the sliding plate. The clamping column has a polygonal cross-section. An anti-detachment ring tube is arranged at the top of the clamping column. A wheel seat is provided at the bottom of the clamping column. The pressure pulley is rotatably mounted on the wheel seat. A tension spring supports the wheel seat and the lower surface of the sliding plate.

[0019] By adopting the above technical solution, when the upper die holder of the die-cutting machine separates from the lower die holder, there is a gap between the pressure roller and the strip under the action of the anti-detachment ring tube. When the upper die holder of the die-cutting machine closes to the lower die holder, the pressure roller will first abut against the edge of the strip. As the upper die holder of the die-cutting machine continues to descend to close with the lower die holder, the tension spring is further compressed, the pressing force of the pressure roller on the edge of the strip increases, and the strip cannot slip.

[0020] Optionally, the anti-detachment ring tube is slidably sleeved on the clamping column, and a locking bolt is threaded onto the anti-detachment ring tube, the locking bolt being used to abut against the surface of the clamping column.

[0021] By adopting the above technical solution, workers can adjust the position of the anti-detachment ring tube on the clamping column by using the locking bolt, thereby adjusting the tension spring force and reducing the possibility of the strip edge being crushed.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Because the die-cutting machine operates continuously while the strip is conveyed intermittently, when the winding machine collects the strip, there is a gap between the pressure roller and the strip, and the strip is wound normally. When the winding machine stops winding the strip, the upper die holder of the die-cutting machine closes onto the lower die holder. At this time, the clamping assembly drives the pressure roller to press against the edge of the strip, so that the strip between the upper die holder and the lower die holder of the die-cutting machine cannot slip, thereby improving the die-cutting quality of the strip.

[0024] 2. When the upper die holder of the die-cutting machine is closed with the lower die holder, the drive rod will abut against one end of the transmission rod, the transmission rod will rotate, and the other end of the transmission rod will abut against and push the pressure block. The pressure block drives the clamping frame to rotate, and the clamping frame drives the pressure roller to rotate synchronously through the mounting shaft, so that the pressure roller presses against the edge of the strip, thereby preventing the strip between the upper die holder and the lower die holder of the die-cutting machine from slipping;

[0025] 3. When the upper die holder of the die-cutting machine separates from the lower die holder, there is a gap between the pressure roller and the strip under the action of the anti-detachment ring tube. When the upper die holder of the die-cutting machine closes to the lower die holder, the pressure roller will first abut against the edge of the strip. As the upper die holder of the die-cutting machine continues to descend to close with the lower die holder, the tension spring is further compressed, and the pressing force of the pressure roller on the edge of the strip increases, so the strip cannot slip.

[0030] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0031] This application discloses a lifting rod device for a die-cutting machine.

[0032] Example 1

[0033] Reference Figure 1 A lifting device for a die-cutting machine includes a processing table 2, on which a die-cutting machine 3 is bolted. The upper die base of the die-cutting machine 3 is vertically slidably arranged directly above the lower die base of the die-cutting machine 3. An unwinding machine 4 is arranged at the feeding end of the die-cutting machine 3, and a winding machine 5 is arranged at the output end of the die-cutting machine 3. The die-cutting machine 3, the unwinding machine 4, and the winding machine 5 are all prior art. The strip 1 slides through between the upper die base and the lower die base of the die-cutting machine 3.

[0034] Reference Figure 1 and Figure 2 The processing table 2 is equipped with a pressure roller 6 and a pressing assembly 7. The pressure roller 6 is located on both sides of the die-cutting machine 3. When the winding machine 5 winds the strip 1, there is a gap between the pressure roller 6 and the strip 1. When the winding machine 5 stops winding the strip 1, the pressing assembly 7 is used to drive the pressure roller 6 to press the edge of the strip 1 onto the processing table 2.

[0035] The worker passes the strip 1 unwound from the unwinding machine 4 between the upper and lower die seats of the die-cutting machine 3, and then winds it onto the take-up shaft of the take-up machine 5.

[0036] Reference Figure 1 and Figure 2 The clamping assembly 7 includes a vertical plate 701 bolted to the processing table 2. A clamping frame 702 is rotatably connected to the vertical plate 701. The clamping frame 702 is located above the strip 1. A counterweight rod 703 is welded to the side of the clamping frame 702 closest to the die-cutting machine 3. A mounting shaft 704 is welded to the side of the clamping frame 702 furthest from the die-cutting machine 3. The pressure roller 6 is bolted to the mounting shaft 704.

[0037] Reference Figure 1 and Figure 2 The rotation center of the clamping frame 702 is located between the counterweight rod 703 and the mounting shaft 704. An end plate 10 is welded to the top of the upright plate 701. An anti-locking spring 11 is supported between the side of the clamping frame 702 near the die-cutting machine 3 and the end plate 10. Under the gravity of the counterweight rod 703, there is a gap between the pressure roller 6 and the strip 1. A drive component 705 is arranged on the processing table 2 to drive the pressure roller 6 to press the edge of the strip 1.

[0038] Reference Figure 1 and Figure 2 The drive component 705 includes a mounting block 7051 bolted to the upper die base of the die-cutting machine 3. A vertical drive rod 7052 is arranged on the mounting block 7051. The drive rod 7052 is threaded to the mounting block 7051. An anti-loosening nut 9 is threaded to the drive rod 7052. The anti-loosening nut 9 is used to abut against the mounting block 7051. A pressure block 7053 is integrally formed on the side of the clamping frame 702 near the die-cutting machine 3. A gate-type bracket 7054 is bolted to the processing table 2.

[0039] Reference Figure 1 and Figure 2 A transmission rod 7055 with an L-shaped cross-section is rotatably connected to the portal bracket 7054. One end of the transmission rod 7055 is located directly below the drive rod 7052, and the other end is located directly below the pressure block 7053. Both ends of the transmission rod 7055 are rotatably connected to transition wheels 8. The transition wheel 8 at one end of the transmission rod 7055 is used to abut against the end of the drive rod 7052 and to roll in cooperation with the circumferential surface of the drive rod 7052.

[0040] Reference Figure 1 and Figure 2 The transition wheel 8 at the other end is used to abut against and roll with the lower surface of the pressure block 7053. When the upper die holder of the die-cutting machine 3 is separated from the lower die holder of the die-cutting machine 3, the transition wheel 8 at the end of the transmission rod 7055 abuts against the bottom end of the drive rod 7052. At the same time, there is a gap between the pressure roller 6 and the strip 1. When the upper die holder of the die-cutting machine 3 is closed with the lower die holder of the die-cutting machine 3, the pressure roller 6 presses against the edge of the strip 1.

[0041] When the upper and lower die holders of the die-cutting machine 3 are not closed, under the action of the anti-locking spring 11 and the counterweight rod 703, the pressure block 7053 on the clamping frame 702 presses against the transition wheel 8 at one end of the transmission rod 7055, while the transition wheel 8 at the other end of the transmission rod 7055 abuts against the bottom end of the drive rod 7052. At this time, there is a gap between the pressure roller 6 and the edge of the upper surface of the strip 1.

[0042] When the upper die holder of the die-cutting machine 3 is engaged with the lower die holder, the bottom end of the drive rod 7052 will abut against the transition wheel 8 on the transmission rod 7055. The transition wheel 8 will rotate, and at the same time, the transmission rod 7055 will rotate around its rotation center. The transition wheel 8 at the end of the transmission rod 7055 facing away from the drive rod 7052 will lift the pressure block 7053. The pressure block 7053 will drive the clamping frame 702 to rotate until the clamping frame 702 drives the pressure roller 6 to press against the edge of the strip 1.

[0043] During this process, the anti-locking spring 11 is continuously compressed. At the same time, the transition wheel 8 near the end of the drive rod 7052 just abuts against the circumferential surface of the drive rod 7052. As the upper die holder continues to close to the lower die holder, the transition wheel 8 near the end of the drive rod 7052 rolls between itself and the surface of the drive rod 7052, while the pressure on the edge of the strip 1 remains unchanged.

[0044] The implementation principle of Example 1 is as follows: the worker passes the strip 1 unwound from the unwinding machine 4 between the upper and lower die seats of the die-cutting machine 3, and then winds it onto the winding shaft of the winding machine 5.

[0045] When the upper and lower die holders of the die-cutting machine 3 are not closed, under the action of the anti-locking spring 11 and the counterweight rod 703, the pressure block 7053 on the clamping frame 702 presses against the transition wheel 8 at one end of the transmission rod 7055, while the transition wheel 8 at the other end of the transmission rod 7055 abuts against the bottom end of the drive rod 7052. At this time, there is a gap between the pressure roller 6 and the edge of the upper surface of the strip 1.

[0046] When the upper die holder of the die-cutting machine 3 is engaged with the lower die holder, the bottom end of the drive rod 7052 will abut against the transition wheel 8 on the transmission rod 7055. The transition wheel 8 will rotate, and at the same time, the transmission rod 7055 will rotate around its rotation center. The transition wheel 8 at the end of the transmission rod 7055 facing away from the drive rod 7052 will lift the pressure block 7053. The pressure block 7053 will drive the clamping frame 702 to rotate until the clamping frame 702 drives the pressure roller 6 to press against the edge of the strip 1.

[0047] During this process, the anti-locking spring 11 is continuously compressed. At the same time, the transition wheel 8 near the end of the drive rod 7052 just abuts against the circumferential surface of the drive rod 7052. As the upper die holder continues to close to the lower die holder, the transition wheel 8 near the end of the drive rod 7052 rolls between itself and the surface of the drive rod 7052, while the pressure on the edge of the strip 1 remains unchanged.

[0048] Example 2

[0049] refer to Figure 3The difference between this embodiment and embodiment 1 is that the clamping assembly 7 includes a horizontal screw 706 and a guide rod 707 bolted to the upper die base of the die-cutting machine 3. The axis of the guide rod 707 is parallel to the axis of the horizontal screw 706, and a sliding plate 708 is slidably sleeved on the horizontal screw 706 and the guide rod 707.

[0050] Reference Figure 3 The sliding plate 708 has a positioning nut 709 threaded on both sides along the axis of the horizontal screw 706. A clamping column 710 is vertically slidably inserted on the sliding plate 708. The cross-section of the clamping column 710 is polygonal. An anti-detachment ring tube 711 is arranged on the top of the clamping column 710.

[0051] Reference Figure 3 The anti-detachment ring tube 711 is slidably sleeved on the clamping column 710. The anti-detachment ring tube 711 is threaded with a locking bolt 12. The locking bolt 12 is used to abut against the surface of the clamping column 710. The bottom of the clamping column 710 is welded with a wheel seat 712. The pressure roller 6 is rotatably connected to the wheel seat 712. A tension spring 713 supports the wheel seat 712 and the lower surface of the slide plate 708.

[0052] The implementation principle of Example 2 is as follows: the worker first adjusts the position of the anti-detachment ring tube 711 on the clamping column 710 by locking bolt 12, thereby adjusting the elastic force of tension spring 713, and at the same time keeping a distance between the pressure roller 6 and the upper surface of the strip 1.

[0053] During the process of the upper die holder of the die-cutting machine 3 closing with the lower die holder, the pressure roller 6 will first abut against the edge of the strip 1. As the upper die holder of the die-cutting machine 3 continues to descend, until the upper die holder of the die-cutting machine 3 closes with the lower die holder of the die-cutting machine 3, the tension spring 713 is further compressed, and the pressing force of the pressure roller 6 on the edge of the strip 1 increases, so that the strip 1 cannot slip.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
