[0024] like Figures 1 to 3 As shown, the traction mechanism also includes a traction wheel 4, a pressure wheel 5, a control wheel 6, and a floating wheel 7 arranged in the feed box 3. The traction wheel 4 and the control wheel 6 are rotatably connected to the inner wall of the feed box 3 and both are driven by a motor (not shown in the figure). The two motors are both located on the outer wall of the feed box 3. The control wheel 6 is connected to the pressure wheel 5 through a connecting plate 8. The pressure wheel 5 is rotatably connected to the connecting plate 8, and the pressure wheel 5 is located above the traction wheel 4.
[0025] Through the arrangement of the above structure, after the guide mechanism guides out the cut edge material, the traction wheel 4 and the pressure wheel 5 in the traction mechanism can clamp the edge material and transport it stably, and the control wheel 6 can be rotated according to the needs of the situation to change the distance between the pressure wheel 5 and the traction wheel 4 through the connecting plate 8, adjust the clamping force on the edge material, thereby controlling the linear speed of the traction mechanism transportation to be consistent with the linear speed of the film material body transported on the main machine of the equipment, which is beneficial to the stable slitting of the film and ensures the stability of the tension.
[0026] like Figures 1 to 3 As shown, a connecting arm 9 is provided in the feed box 3, one end of the connecting arm 9 is rotatably connected to the inner wall of the feed box 3, and a floating wheel 7 is rotatably connected to the other end of the connecting arm 9. A floating roller potentiometer (not shown in the figure) is provided on the outer wall of the feed box 3, and the floating roller potentiometer is connected to one end of the connecting arm 9 connected to the feed box 3, and is electrically connected to the motor corresponding to the control wheel 6.
[0027] Through the arrangement of the above structure, when the tension on the edge material changes, the position of the floating wheel 7 will rise or fall, and the position signal will be fed back to the motor corresponding to the control wheel 6 through the connecting arm 9, so that the control wheel 6 can adjust the position of the pressing wheel 5, so that the pressing wheel 5 and the traction wheel 4 can stably clamp the edge material to prevent the edge material from loosening. At the same time, the tension on the edge material is also more stable to avoid film breakage as much as possible.

[0031] By setting the above structure, a small opening 17 for feeding is formed between the short side of the limiting rod 14 and the second guide wheel 12, which can limit and guide the edge material and prevent it from falling off.
[0032] like Figures 1 to 3 As shown, the narrow edge material after being cut passes through the guide wheel 2 and the ring 21, and then enters the guide box 3, and then the pressure wheel 5 and the traction wheel 4 are aligned for stable clamping and transportation, so that after the edge material is guided out from the discharge port 11, it can enter the air duct 16 and be discharged through the air duct 16.
