Description

Technical Field

[0001] The utility model relates to the technical field of plastic film production equipment, and more specifically to a roll-splitting equipment for plastic film production. Background Art

[0002] Plastic film, made from polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, is used for packaging and as a coating. Plastic packaging and its products are increasingly gaining market share, especially composite plastic flexible packaging, which is widely used in the food, pharmaceutical, and chemical industries. Food packaging, such as beverage packaging, frozen food packaging, retort food packaging, and fast food packaging, accounts for the largest proportion. These products have brought great convenience to people's lives.

[0003] The shortcomings of the existing technology: When producing plastic film, different widths are required, so the plastic film needs to be slit and then rolled up. However, the traditional slitting device is not convenient for adjusting the plastic slitting width and is difficult to meet people's usage needs. For this reason, we propose a rolling equipment for plastic film production. Utility Model Content

If the blade 7 is to be increased or decreased, the first merging block 401 and the second merging block 402 in the clamping frame 4 are separated, and the blade 7 can be installed and removed. At the same time, according to the distance between the blades 7, the limiting sleeves 10 of different degrees are replaced to limit the distance between the blades 7. Finally, under the action of the clamping block 9 and the clamping slot 8, when the driving shaft 5 rotates, it will drive the installation sleeve 6 to rotate, and the installation sleeve 6 will drive the blade 7 to rotate. It is more convenient to replace and adjust, and can be adjusted freely to complete the slitting of plastic films of different sizes.

[0022] Furthermore, a second mounting bracket 11 is fixedly connected to the upper end of the base 1, a connecting rod 12 is fixedly connected inside the mounting bracket, and a guide roller 13 is rotatably connected to the circumferential surface of the connecting rod 12. During operation, under the action of the guide roller 13, when the plastic film is conveyed around, it can guide the conveying of the plastic film so that it can contact the blade 7 and complete the slitting of the plastic film.

[0023] Furthermore, a third mounting bracket 14 is fixedly connected to the upper end of the base 1, and a mounting rod 15 is rotatably connected inside the third mounting bracket 14. A winding roller 16 is fixedly connected to the circumferential surface of the mounting rod 15. During operation, by controlling the rotation of the mounting rod 15, the mounting rod 15 will drive the winding roller 16 to rotate, thereby achieving the effect of winding up the plastic film after slitting. At the same time, the size of the winding roller 16 needs to be adapted to the size of the plastic film after slitting.

[0024] Furthermore, a first motor 17 is fixedly connected to the left end of the third mounting frame 14, and the output end of the first motor 17 is fixedly connected to the mounting rod 15. When working, by controlling the operation of the first motor 17, the first motor 17 will rotate the mounting rod 15, thereby achieving the effect of driving the winding roller 16 to rotate and wind up the plastic film.

[0025] Furthermore, a second motor 18 is fixedly connected to the left end of the first mounting frame 2, and the output end of the second motor 18 is fixedly connected to the drive shaft 5. During operation, by controlling the operation of the second motor 18, the second motor 18 will drive the drive shaft 5 to rotate, and the drive shaft 5 will drive the mounting sleeve 6 to rotate, and the mounting sleeve 6 will drive the blade 7 to rotate to complete the slitting of the plastic film.

[0026] Furthermore, a rotating seat 19 is fixedly connected to the lower end of the base 1, and a bidirectional threaded rod 20 is rotatably connected to the rotating seat 19. The circumferential surface of the bidirectional threaded rod 20 is threadedly connected to a connecting block 21, and the connecting block 21 is fixedly connected to the first merging block 401 and the second merging block 402. During operation, when the position of the blade 7 needs to be adjusted, the bidirectional threaded rod 20 is rotated, and the bidirectional threaded rod 20 will drive the connecting block 21 to move, thereby driving the first merging block 401 and the second merging block 402 to move to both sides.

[0027] The working principle of the present invention is as follows: the distance between the blades 7 is adjusted according to the size of the plastic film to be cut according to the needs. If the blade 7 is increased or decreased, the bidirectional threaded rod 20 is rotated, and the bidirectional threaded rod 20 drives the connecting block 21 to move, thereby driving the first merging block 401 and the second merging block 402 to move to both sides. At this time, the blade 7 and the limit sleeve 10 can be taken out from the installation sleeve 6, and then readjusted and installed, thereby achieving the effect of facilitating the adjustment of the distance between the blades 7, and being able to complete the slitting of plastic films of different sizes. Subsequently, under the action of the guide roller 13, when the plastic film is cut, the distance between the blades 7 and the limit sleeve 10 can be adjusted. When the material film is conveyed around, it can guide the conveying of the plastic film so that it can contact the blade 7. By controlling the operation of the second motor 18, the second motor 18 will drive the drive shaft 5 to rotate, and the drive shaft 5 will drive the mounting sleeve 6 to rotate, and the mounting sleeve 6 will drive the blade 7 to rotate, thereby completing the slitting of the plastic film. At the same time, by controlling the operation of the first motor 17, the first motor 17 will rotate the mounting rod 15, and the mounting rod 15 will drive the winding roller 16 to rotate, thereby achieving the effect of winding the slit plastic film. At the same time, the size of the winding roller 16 needs to be adapted to the size of the plastic film after slitting.
