[0002] In the production process of plastic film, it is usually necessary to cut the wide film into the required width and then cut it.

[0003] Existing slitting and cutting devices suffer from low slitting accuracy, resulting in uneven film edges and burrs during the cutting process, which affects product quality.

[0004] Therefore, there is an urgent need for a plastic film cutting and slitting device that can improve cutting accuracy and reduce burrs. Utility Model Content

The lifting mechanism includes vertical guide components on both sides of the support structure, and a lifting drive component is disposed within each vertical guide component. The lifting drive component is drively connected to a mounting bracket, and the mounting bracket is guided to the vertical guide component via a sliding fit. The adjusting mechanism includes a support beam spanning above the support structure, the support beam having multiple positioning parts extending along its length, and a movable component slidably mounted on the support beam. The movable component is detachably connected to the positioning parts via an elastic positioning component, and the slitting blade is connected to the bottom of the movable component.

The transmission slider is fixedly connected to the mounting bracket, and the transmission slider is connected to a limit slider, which slides in the second slide groove.

[0009] As a further technical solution of this utility model, the rotating part also includes a rubber sleeve, and the spacing of the positioning part is set to correspond to the interval distance of the film limiting component.

[0012] The beneficial effects of this utility model are as follows:

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Figure 1 A schematic diagram of the overall internal structure of the slitting and cutting device for plastic film processing is shown. Figure 1The plastic film processing slitting and cutting device includes a worktable 1, a lifting mechanism, an adjusting mechanism, and a slitting blade 22. The worktable 1 is provided with a support structure 2 and a conveying assembly 3, and the conveying assembly 3 is provided with a film conveying channel 4. The lifting mechanism includes vertical guide assemblies provided on both sides of the support structure 2, and a lifting drive assembly is provided inside the vertical guide assembly. The lifting drive assembly is connected to a mounting bracket 10, and the mounting bracket 10 forms a guiding connection with the vertical guide assembly through a sliding fit. The adjustment mechanism includes a support beam 12 spanning above the support structure 2. The support beam 12 has multiple positioning parts 13 extending along its length. The adjustment mechanism also includes a movable component 21 slidably mounted on the support beam 12. The movable component 21 is detachably connected to the positioning parts 13 via an elastic positioning component. A dividing blade 22 is connected to the bottom of the movable component 21. The film passes above the mounting bracket 10. Under the action of the lifting mechanism, the height of the mounting bracket 10 is controlled, so that the mounting bracket 10 carries the film and moves to the bottom of the dividing blade 22, where it is divided and cut by the dividing blade 22. At the same time, by controlling the adjustment mechanism, the row spacing of the dividing blades 22 sliding on the two sets of support beams 12 is adjusted, so that the cutting and dividing operation steps for films of different widths can be achieved.

[0021] At least two sets of film limiting components 11 are spaced apart on the mounting bracket 10, forming film separation intervals between adjacent film limiting components 11. Under the action of the film separation intervals, films of different widths are separated and cut in conjunction with the separating and cutting mechanism. The vertical guide component includes a first slide groove 5 and a second slide groove 9 symmetrically arranged on the inner wall of the support structure 2. The lifting drive component includes a screw transmission mechanism 6 arranged in parallel and a transmission slider 7 cooperating with it. The transmission slider 7 is fixedly connected to the mounting bracket 10. The transmission slider 7 is connected to a limiting slider 8, and the limiting slider 8 slides in the second slide groove 9. Under the action of the vertical guide component, the mounting bracket 10 moves smoothly up and down within the support structure 2, so that the film placed on the mounting bracket 10 can be stably cut by the bottom end of the dividing blade 22. It is worth noting that the drive switches of the screw transmission mechanism 6 and the transmission slider 7 are on the outside of the device, which is a direct reference to the prior art and will not be described in detail here.

[0022] Figure 2 It shows Figure 1A schematic diagram of the adjustment mechanism is shown. The spacing of the positioning part 13 corresponds to the interval distance of the film limiting component 11. Under the same spacing, the bottom end of the dividing blade 22 can accurately match the length of the supporting beam 12 to cut and divide the film that is unfolded and abutting on the mounting bracket 10 to the required size. When the mounting bracket 10 moves upward under the action of the lifting mechanism, the bottom end of the dividing blade 22 can accurately lock into the film dividing area, while avoiding damage to the blade tip at the bottom end of the dividing blade 22. A rolling guide structure 23 is provided between the moving component 21 and the supporting beam 12. The rolling guide structure 23 includes multiple rolling elements arranged along the moving direction of the moving component 21. Under the rolling action of the rolling elements, when the moving component 21 drives the dividing blade 22 to move on the supporting beam 12, the rolling action of the rolling elements reduces the friction of the moving component 21 sliding on the supporting beam 12, avoiding jamming during the movement.

[0023] Figure 3 It shows Figure 2 Enlarged structural diagram at point A in the middle; Figure 3 In the process, the elastic positioning component includes a retractable positioning pin 14 and a reset elastic element 17. The positioning pin 14 is linearly slidably connected to the moving component 21 through a sliding guide mechanism. The sliding guide mechanism includes a slot 18 and a sliding block 19. The positioning pin 14 is connected to a pull rod 15, and an adjusting inner rod 16 is connected to the side of the pull rod 15 away from the positioning pin 14. The adjusting inner rod 16 moves within the slot 18 under the connection of the reset elastic element 17. Slide rails 20 are symmetrically provided on the inner wall of the slot 18, and slide rails 20 are slidably connected within the slide rails 20. There are sliding blocks 19, all of which are installed on the outer wall of the adjusting inner rod 16. When it is necessary to adjust the position of the dividing blades 22, under the elastic potential energy of the reset elastic element 17, the pull rod 15 is pulled upward, causing the positioning pin 14 to disengage from the locking state of the positioning part 13. Then, in conjunction with the rolling action of the rolling guide mechanism 23, the distance between the two sets of dividing blades 22 is adjusted. When it is necessary to limit the distance between the two sets of dividing blades 22, the positioning pin 14 is inserted into the positioning part 13 at the appropriate position. The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
