Description

Technical Field

[0001] This utility model belongs to the field of protective film production technology, and relates to a cutting device for protective film production. Background Technology

[0002] After the protective film is produced, it is usually necessary to use an edge-cutting device to trim the edges to ensure that the edges are flush. However, with existing edge-cutting devices, the scrap edges of the protective film that are cut off are easily rolled up to the bottom of the cutter due to their light weight, which affects the winding of the trimmed protective film. The scrap edges need to be collected and cleaned manually, which is time-consuming and labor-intensive, and reduces the efficiency of edge-cutting. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a cutting device for protective film production. This solves the problem that in existing cutting devices, the waste edges of the protective film cut off are easily rolled up to the lower end of the cutter due to their light weight, affecting the winding of the cut protective film. Furthermore, the waste edges need to be collected and cleaned manually, which is time-consuming, labor-intensive, and affects the cutting efficiency.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A cutting device for producing protective film, characterized in that it includes a worktable, a cutting table in the middle of the worktable, a feeding roller and a take-up roller rotatably connected to both sides of the cutting table, a first drive motor for driving the take-up roller to rotate on the worktable, a second drive motor symmetrically arranged on the side of the cutting table near the take-up roller, a cutting wheel fixedly connected to the output shaft of the second drive motor, a third drive motor between the cutting wheel and the take-up roller, and a collecting roller fixedly connected to the output shaft of the third drive motor.

[0006] In the aforementioned edge-cutting device for producing protective film, a first push rod motor is symmetrically arranged on the cutting table, and a second drive motor is fixedly connected to the push rod of the first push rod motor.

[0007] In the aforementioned edge-cutting device for producing protective film, the cutting table has a scale line on one end near the winding roller.

[0008] In the aforementioned edge-cutting device for producing protective film, a second push rod motor is fixedly connected to the worktable, and a third drive motor is fixedly connected to the push rod of the second push rod motor.

[0009] In the aforementioned edge-cutting device for producing protective film, several guide rollers are rotatably connected to the worktable.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] The third drive motor drives the collecting roller to rotate, and the waste edge is rolled onto the collecting roller. This prevents the cut waste edge of the protective film from being rolled to the bottom of the cutter due to its light weight, which would affect the winding of the cut protective film. At the same time, it saves the time of manual cleaning and improves the cutting efficiency. The first push rod motor drives the second drive motor and the cutting wheel to move and adjust the position of the cut edge. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figure 1 As shown,

[0017] A cutting device for producing protective film, characterized in that it includes a workbench 2, a cutting table 3 is provided in the middle of the workbench 2, a feeding roller 4 and a take-up roller 5 are rotatably connected to both sides of the cutting table 3, a first drive motor is provided on the workbench 2 to drive the take-up roller 5 to rotate, a second drive motor 6 is symmetrically provided on the side of the cutting table 3 near the take-up roller 5, a cutting wheel 7 is fixedly connected to the output shaft of the second drive motor 6, a third drive motor 8 is provided between the cutting wheel 7 and the take-up roller 5, and a collecting roller 9 is fixedly connected to the output shaft of the third drive motor 8.

[0018] In this embodiment, the protective film roll that needs to be trimmed is inserted into the feeding roller 4, and the end of the protective film is connected to the take-up roller 5. The first drive motor drives the take-up roller 5 to rotate, so that the protective film is conveyed and wound up. The second drive motor 6 drives the cutting wheel 7 to rotate, trimming the protective film being conveyed and wound up. The waste edge generated by trimming is fixed on the collecting roller 9. The third drive motor 8 drives the collecting roller 9 to rotate, and the waste edge is wound up onto the collecting roller 9. This prevents the cut waste edge of the protective film from being rolled up to the lower end of the cutter due to its light weight, which would affect the winding of the trimmed protective film. At the same time, it saves the time of manual cleaning and improves the trimming efficiency.

[0019] In this embodiment, a first push rod motor 10 is symmetrically arranged on the cutting table 3, and a second drive motor 6 is fixedly connected to the push rod of the first push rod motor 10. The first push rod motor 10 drives the second drive motor 6 and the cutting wheel 7 to move, thereby adjusting the position of the cutting edge.

[0020] In this embodiment, the cutting table 3 has a scale line on the end near the winding roller 5. The scale line facilitates more precise determination of the cutting edge position.

[0021] In this embodiment, a second push rod motor 11 is fixedly connected to the worktable 2, and a third drive motor 8 is fixedly connected to the push rod of the second push rod motor 11. During waste edge winding, the second push rod motor 11 drives the third drive motor 8 and the collecting roller 9 to move back and forth, so that the waste edge is wound up to different positions on the collecting roller 9.

[0022] In this embodiment, a plurality of guide rollers 12 are rotatably connected to the worktable 2.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0024] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
