Technical realization elements of plastic film trimming machine

Technical implementation elements:

5. In order to improve the problem that it takes a long time for workers to adjust the position of the blade when cutting films of different widths, the present technology provides a film edge trimmer.

6. A plastic film edge trimmer provided by this technology adopts the following technical solutions:

7. A plastic film edge trimming machine, comprising a body, a side wall of the body is rotatably connected with a tool holder shaft, the tool holder shaft is placed horizontally, the tool holder shaft is connected with a rotating mechanism for adjusting the position of the tool holder shaft, and a tool holder shaft is installed on the tool holder shaft. There are multiple cutter groups. The cutter group includes two cutters. The cutters are located at both ends of the cutter holder shaft and are symmetrically distributed, and the cutters are perpendicular to the cutter holder shaft. The angle is arranged along the axial direction of the tool holder axis.

8. By adopting the above technical solution, when it is necessary to cut films of different widths, the shaft of the knife holder is rotated, and the different cutter groups are rotated to the cutting position, and the film can be cut, which avoids workers spending a lot of time readjusting the cutting knife. location, work more efficiently and improve production efficiency.

9. Optionally, the rotating mechanism includes a support arm, one end of the support arm is sleeved on the tool holder shaft to be rotatably connected to the tool holder shaft, the other end of the support arm is rotatably connected to the side wall of the body, and the support arm is installed below the support arm to drive the support arm to rotate. of the cylinder.

10. By adopting the above technical solution, the cylinder drives the support arm to rotate, and drives the tool holder shaft to rotate in the body. When the cutter group needs to be replaced, the support arm is supported by the cylinder to drive the tool holder shaft to rotate upward, and the tool holder is lifted. The shaft avoids the interference between the cutter and other rollers, prevents the cutter from being damaged, and facilitates the replacement of the cutter group.

11. Optionally, a runner is fixedly connected to both ends of the tool holder shaft, and a grip rod is fixedly connected to the outer edge of the runner.

12. By adopting the above technical solution, when the tool holder shaft needs to be rotated, hold the handle to rotate the runner, and then drive the rotation of the tool holder shaft to realize the replacement of the cutter group. The setting of the runner makes the tool holder shaft rotate. More convenient and labor-saving.

13. Optionally, there is a knife groove roller in the body, the two ends of the knife groove roller are rotatably connected with the body, and the to the knife groove roller is provided with an annular knife groove, and the annular knife groove is cut with the knife holder shaft. The position of the knife corresponds.

14. By adopting the above technical solution, when the film is attached to the notch roller for cutting, the tip of the cutter penetrates into the notch to prevent the cutter from colliding with the roller surface of the notch roller and to avoid damage to the cutter.

15. Optionally, a positioning wheel is sleeved on the tool holder shaft. The positioning wheel is located outside the second support arm. The positioning wheel is fixedly connected with the tool holder shaft. The positioning wheel is provided with a plurality of through holes, and the positioning wheel is provided with The positioning pin is provided with a positioning hole on the inner side wall of the body, and the diameter of the positioning hole is adapted to the positioning pin.

16. By adopting the above technical solution, after adjusting the position of the cutter group, the positioning pin can be inserted through the through hole of the positioning wheel and inserted into the positioning hole on the inner side wall of the machine body to realize the positioning of the tool holder shaft and prevent the tool holder shaft from cutting. Rotation occurs.

17. Optionally, the side walls of the body are provided with support rollers, both ends of the support rollers are fixedly connected to the side walls of the body, the roller surfaces of the support rollers are oval, the two ends of the support rollers are rotatably connected to the side walls of the body, and the side walls of the body are provided with A drive motor, the output shaft of the drive motor is penetrated through the side wall of the body and is fixedly connected with the support roller.

18. By adopting the above technical solutions, when the film is wound, the elliptical roller surface can provide support for the film intermittently, so that the tension force of the film is increased, and there will be no gap in the winding of the film. The roll is more even.

19. Optionally, the lower part of the cutter is provided with a base, the base is sleeved on the tool holder shaft and is slidably connected to the tool holder shaft, and the base is in contact with the surface of the tool holder shaft.

20. By adopting the above technical solutions, the position of the cutter on the shaft of the knife holder can be adjusted according to the actual production needs, so as to meet the cutting of films of different widths, and the installation of the cutter is more flexible.

21. Optionally, the side wall of the base is threadedly connected with bolts, and the bolts are penetrated through the side wall of the base and abut against the shaft of the tool holder.

22. By adopting the above technical solutions, after tightening the bolts, the base and the surface of the tool holder shaft can be more closely fitted, the cutter is less likely to rotate, and the cutter is more stable.

23. To sum up, the present technology includes at least one of the following beneficial technical effects:

24.1. There are multiple cutter groups on the knife holder shaft. When it is necessary to cut films of different widths, the cutter holder shaft can be rotated to realize the cutter replacement, so as to avoid workers spending a lot of time debugging the position of the cutter, improve production efficiency;

25.2. The support roller can provide support force for the film intermittently, and tighten the film, so that the film can be wound more tightly without leaving gaps, and the film can be wound more evenly.
