[0022] Embodiment: The utility model provides a waste edge cutting and winding device for plastic film, such as Figures 1 to 6As shown, it includes a stand 1, a feed roller group 2, a discharge roller group 3, a cutting component and a winding component. The feed roller group 2 and the discharge roller group 3 are respectively provided on the left and right sides of the top of the stand 1. The feed roller group 2 and the discharge roller group 3 are two motor-driven conveying rollers that are used in conjunction with each other, and the two motor-driven conveying rollers in the same group rotate in opposite directions to each other, so as to smoothly convey the plastic film a. A cutting component is provided in the middle of the stand 1, and the cutting width of the waste edge b of the film can be flexibly adjusted according to the actual use situation through the cutting component, and the use range is wide; the left side of the top of the stand 1 is close to the cutting A winding component is provided at the component, and the winding component includes a mounting seat 11, a servo motor 12, a winder and a quantitative sensing component. A mounting seat 11 is provided on the top left side of the stand 1, and a servo motor 12 is installed on the mounting seat 11.

A quantitative sensing component is also provided on the mounting seat 11, and the quantitative sensing component can realize automatic detection and sensing of the winding thickness of the film waste edge b, which is conducive to precise control of the winding thickness of the film waste edge b.

[0023] Further, such as Figure 4 and Figure 5 As shown, the winder includes a winding slot disk 13, a support rod 14 and an elastic member 15. The output shaft end of the servo motor 12 is connected to the winding slot disk 13. Five support rods 14 are arranged in the slot hole at the bottom of the winding slot disk 13 for sliding at uniform intervals along the circumferential direction. By synchronously retracting and adjusting each support rod 14 toward the center of the winding slot disk 13, the film waste edge b wound thereon can be conveniently blanked; an elastic member 15 is respectively connected between the end of each support rod 14 and the side wall of the slot hole at the bottom of the winding slot disk 13. The elastic member 15 is a compression spring, which can provide an outward tensioning force to the support rod 14 connected thereto, so as to wind and reel the cut film waste edge b; a discharge hole 100 is opened on the left side of the top of the stand 1, and the discharge hole 100 is located directly below the support rod 14, which is conducive to the accurate drop of the wound and cut film waste edge b from the discharge hole 100, and the container can be placed under the discharge hole 100 to conveniently collect and process the film waste edge b.

[0024] Further, such as Figure 4 and Figure 6As shown, the quantitative sensing component includes a guide sleeve 16, a mounting frame 17, a contact roller 18, a reset member 19, a pressure sensor 20 and an electric clamp 21. A guide sleeve 16 is provided on the upper part of the mounting seat 11 near the side of the winding groove disc 13. The mounting frame 17 is slidably provided in the guide sleeve 16. The contact roller 18 is provided on the rotating sleeve of the mounting frame 17. A reset member 19 is connected between the upper part of the mounting frame 17 and the side wall of the guide sleeve 16. A pressure sensor 20 capable of contacting the mounting frame 17 is provided in the middle of the mounting seat 11. An electric clamp for automatically retracting the support rod 14 is provided at the bottom of the guide sleeve 16. 21, and the electric clamp 21 is electrically connected to the pressure sensor 20. The electric clamp 21 can be a small electric clamp on the existing market (model EFG-12 or EFG-8, etc.); when the waste edge b of the film is rolled up to a predetermined thickness value, it can squeeze the contact roller 18 so that the contact roller 18 and the mounting frame 17 thereon can abut against the pressure sensor 20, and then the pressure sensor 20 sends the sensed signal to the electric clamp 21 through the controller, so that the electric clamp 21 can control the two clamping arms thereon to retract each other to automatically tighten the support rod 14.

[0025] Further, such as Figures 1 to 3 As shown, the cutting assembly includes an adjusting frame 4, an adjusting rod 5, a movable seat 6 and a cutter 7. An adjusting frame 4 is respectively provided in the middle of the front and rear sides of the top of the stand 1. The adjusting frame 4 is rotatably connected to the adjusting rod 5. The adjusting frame 4 is horizontally slidably connected to the movable seat 6, and the movable seat 6 is threadedly connected to the adjusting rod 5. A cutter 7 is provided on the upper part of the movable seat 6. By rotating the adjusting rod 5, the positions of the movable seat 6 and the cutter 7 can be conveniently adjusted, which is conducive to conveniently adjusting the cutting width of the waste edge b of the plastic film a.

[0026] Further, such as Figure 3 As shown, an electric shear 8 is also included. The electric shear 8 for automatically cutting the waste edge b of the film is arranged on the left side of the movable seat 6, and the electric shear 8 is also electrically connected to the pressure sensor 20. The electric shear 8 can be the pneumatic scissors commonly used in the prior art (the blade model can be HS-K56).

[0027] In addition, if Figures 1 to 3 As shown, a positioning member is also included, and the positioning member includes a connecting seat 9 and a positioning roller 10. A connecting seat 9 is provided on the right side of the two adjustment frames 4, and a positioning roller 10 is rotatably connected between the upper parts of the two connecting seats 9. The two positioning rollers 10 can be used to pull and limit the plastic film a passing through it, which is beneficial for the electric shears 8 to cut the waste edge b of the plastic film a.

[0028] When in use, the plastic film a is passed through the feed roller group 2 and passed between the positioning rollers 10 in the middle of the stand 1. The plastic film a is continuously and smoothly conveyed by controlling the feed roller group 2 to start. The positioning rollers 10 can realize the directional guidance and conveying of the plastic film a, and cooperate with the cutter 7 to cut the film waste edge b on the plastic film a; the position of the movable seat 6 and the cutter 7 thereon can be adjusted by rotating the adjusting rod 5, so that the cutter 7 can accurately cut the waste edge of the plastic film a, which is conducive to meeting the cutting requirements of different widths of the film waste edge b; the cut plastic film a is passed through the discharge roller group 3, and the cut film waste edge b is passed through the electric shears 8 and wound around the outside of the support rod 14. Starting the servo motor 12 can drive the support rod 14 on it to rotate through the winding slot disc 13 to wind the film waste edge b. The elastic force of the elastic member 15 can support and tension the support rod 14 on it. When the film scrap b on the support rod 14 is rolled up to a certain thickness, the contact roller 18 moves outward as the thickness of the film scrap b increases. When the mounting bracket 17 contacts and abuts the pressure sensor 20, a signal is sent out after the pressure on the pressure sensor 20 reaches a preset value, thereby enabling the electric clamp 21 to control the arc clamp arms thereon to retract each other, thereby pushing the support rod 14 to automatically tighten toward the middle, so that the support rod 14 can be separated from the film scrap b after rolling up. At the same time, the electric shears 8 is started and can automatically cut the film scrap b, that is, complete a rolling cycle operation, and the film scrap b coil after rolling up and cutting will automatically fall down from the blanking hole 100, which is conducive to the convenient automatic loosening and blanking of the film scrap b after rolling up, which not only helps to reduce the space occupied, but also has a high degree of automation.

[0029] It should be understood that the above description is only for illustrative purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be within the scope of the claims herein.
