Description

Technical Field

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

[0002] With the continuous development of the economy, the application of protective film has become increasingly widespread. During the production process, protective film needs to be slit. Existing protective film slitting devices typically involve first inserting the protective film roll onto a support roller, then rotating the support roller to drive the protective film roll to rotate, and finally using a cutting blade to slit the rotating protective film roll. During the slitting process, the protective film roll is not properly secured, which can easily lead to misalignment and inaccurate slitting. After slitting, the slit protective film roll needs to be manually removed from the support roller, which is inconvenient, time-consuming, and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a slitting device for protective film production. This device solves the problems that arise during the slitting process, the protective film rolls are not properly secured, which can easily lead to roll misalignment and inaccurate slitting. Furthermore, after the protective film rolls are slitted, they need to be manually removed from the support rollers, which is inconvenient, time-consuming, and labor-intensive.

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

[0005] A slitting device for producing protective film, characterized in that it includes a base, a support plate fixedly connected to the base, a support roller slidably passing through the support plate, a first push rod motor fixedly connected to the base on the left side of the support plate, the push rod of the first push rod motor being connected to the support roller, a second push rod motor fixedly connected to the base on the right side of the support plate, a fixed plate fixedly connected to the push rod of the second push rod motor, a cylindrical insert block provided in the middle of the fixed plate, the insert block corresponding to the support roller, and a cutting assembly provided at the upper end of the support plate.

[0006] In the above-mentioned slitting device for producing protective film, the cutting assembly includes a third push rod motor, which is fixedly connected to the upper end of the support plate. A fourth push rod motor is fixedly connected to the push rod of the third push rod motor, and a drive motor is fixedly connected to the push rod of the fourth push rod motor. A cutting wheel is fixedly connected to the output shaft of the drive motor.

[0007] In the aforementioned slitting device for producing protective film, the support plate and the fixed plate are provided with a rubber layer.

[0008] In the above-mentioned slitting device for producing protective film, a collection box is provided on the base between the support plate and the second push rod motor.

[0009] In the aforementioned slitting device for producing protective films, the collection box is equipped with an intercepting net.

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

[0011] The protective film roll is well fixed by the cooperation of the support plate, support roller, fixing plate and insert block, which prevents the protective film roll from shifting during the cutting process and causing inaccurate cutting. After a section is cut, the fixing plate moves back and the cut protective film roll falls off automatically, without the need for manual removal of the cut protective film roll from the support roller, which is convenient and labor-saving.

[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 slitting device for producing protective film, characterized in that it includes a base 2, a support plate 3 fixedly connected to the base 2, a support roller 4 slidably passing through the support plate 3, a first push rod motor 5 fixedly connected to the base 2 on the left side of the support plate 3, the push rod of the first push rod motor 5 being connected to the support roller 4, a second push rod motor 6 fixedly connected to the base 2 on the right side of the support plate 3, a fixed disk 7 fixedly connected to the push rod of the second push rod motor 6, a cylindrical insert 8 provided in the middle of the fixed disk 7, the insert 8 corresponding to the support roller 4, and a cutting assembly provided at the upper end of the support plate 3.

[0018] In this embodiment, the protective film roll to be cut is raised to the position corresponding to the support roller 4. Then, the first push rod motor 5 drives the support roller 4 to insert into the protective film roll. After insertion to a certain position, it stops, leaving space for cutting. Then, the second push rod motor 6 drives the fixing plate 7 and the insert block 8 to move towards the protective film roll. The insert block 8 is inserted into the protective film roll, and the fixing plate 7 abuts against the right side of the protective film roll to complete the fixing of the protective film roll. Then, the cutting assembly cuts the film. After cutting a section, the second push rod motor 6 drives the fixing plate 7 to retract, causing the cut protective film roll to fall. Then, the second push rod motor 6 drives the fixing plate 7 to abut against the right side of the protective film roll again, and the first push rod motor 5 drives the support roller 4 to retract a section, leaving space for cutting. The cutting assembly continues to cut, and the operation is repeated until the entire protective film roll is cut. The protective film roll is well fixed by the cooperation of the support plate 3, support roller 4, fixing plate 7 and insert block 8, so as to avoid the protective film roll from shifting during the cutting process and causing inaccurate cutting. After a section is cut, the fixing plate 7 moves back and the cut protective film roll falls off automatically. There is no need to manually remove the cut protective film roll from the support roller 4, which is convenient and labor-saving.

[0019] In this embodiment, the cutting assembly includes a third push rod motor 9, which is fixedly connected to the upper end of the support plate 3. A fourth push rod motor 10 is fixedly connected to the push rod of the third push rod motor 9, and a drive motor 11 is fixedly connected to the push rod of the fourth push rod motor 10. A cutting wheel 12 is fixedly connected to the output shaft of the drive motor 11. The drive motor 11 drives the cutting wheel 12 to rotate, and the fourth push rod motor 10 drives the drive motor 11 and the cutting wheel 12 to descend, cutting the protective film roll. The third push rod motor 9 drives the fourth push rod motor 10, the drive motor 11, and the cutting wheel 12 to move left and right, facilitating the cutting of protective films of different widths according to different needs.

[0020] In this embodiment, the support plate 3 and the fixing plate 7 are provided with a rubber layer 13. The rubber layer 13 on the support plate 3 and the fixing plate 7 makes it less likely for the protective film roll to slip after being clamped, and at the same time will not damage the protective film.

[0021] In this embodiment, a collection box 14 is provided on the base 2 between the support plate 3 and the second push rod motor 6. The cut protective film rolls are collected through the collection box 14.

[0022] In this embodiment, the collection box 14 is equipped with an intercepting net 15. The cut protective film will fall onto the intercepting net 15, while the waste generated during the cutting process will pass through the intercepting net 15 and fall to the bottom of the collection box 14.
