[0002] In the existing field of precision electronic die-cutting, especially in the die-cutting of self-adhesive labels, existing machines need to stop during the waste material unloading process (unloading the waste strip wound on the waste material shaft). In particular, the waste material shaft needs to stop to unload the waste strip on it, or the waste strip may be affected by the excessive conveying distance, which may affect the final winding of the waste strip. Frequent machine downtime will affect the product process yield and ultimately the overall utilization rate of the machine. Summary of the Invention

[0034] An auxiliary material pulling device includes a base plate 1 and two side plates 2 respectively connected to the base plate 1; a roller 3 and a pressure roller 4 are respectively provided between the two side plates 2 from bottom to top, and there is a gap 5 between the roller 3 and the pressure roller 4 that allows the material strip to pass through; the pressure roller 4 can be passed through by a fixed shaft 6, and the fixed shaft 6 is connected to an adjustment device 7 that can adjust the height of the gap 5.

[0035] Its beneficial effects are: this auxiliary material pulling device applies additional traction force to the waste strip, and the machine can run continuously during the waste strip feeding process, reducing the impact of frequent shutdowns on product process defects. In addition, this auxiliary material pulling device can also prevent the waste strip from being conveyed too far, which would affect the normal winding of the waste strip.

[0036] Specifically, in this embodiment, roller 3 is the driving roller and pressure roller 4 is the driven roller. A driving device (not shown in the figure) can be connected to roller 3 to drive its rotation. The driving device can be a motor coaxial with roller 3.

[0037] The waste strip can pass through the gap 5. Driven by the roller 3, the waste strip is wound up towards the waste collection shaft, and the pressure roller 4 positions the waste strip.

[0038] This type of auxiliary material pulling device is generally installed on circular knife machines and composite machines, especially at the front end of the waste material conveyor's receiving shaft.

[0039] Preferably, the top of the side plate 2 is provided with a slot 21.

[0040] Preferably, the adjustment device 7 is respectively disposed on its corresponding side plate 2. Specifically, in this embodiment, each side plate 2 is provided with an adjustment device 7.

[0041] Preferably, the adjusting device 7 includes

[0048] A handle 77 is attached to the fixed shaft 6. For example, in this embodiment, the handle 77 is attached to one end of the fixed shaft 6 to facilitate the disassembly of the fixed shaft 6.

[0049] Its beneficial effect is that the height of gap 5 can be adjusted by a technician rotating knob 75.

[0050] Specifically, when it is necessary to reduce gap 5, the relevant technicians can rotate knob 75 clockwise, causing adjusting rod 74 to move downwards, thereby driving fixed shaft 6 downwards and reducing gap 5. When it is necessary to reduce gap 5, the technicians can rotate knob 75 counterclockwise, at which point spring 76 is used to reset. However, it should be noted that in this embodiment, the adjustment device 7 adjusts gap 5 for fine-tuning.
