Detailed Implementation

[0020] 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.

[0021] like Figures 1 to 4 As shown, a trimming device for membrane processing includes a work box 2. From left to right, the work box 2 is equipped with an unwinding roller 21, a first conveying roller 22 symmetrically arranged above and below the membrane, a trimming mechanism symmetrically arranged in front of and behind the work box 2, and a take-up roller 23.

[0022] The trimming mechanism includes a first drive assembly, a first sliding seat 34, a first lifting motor 33, a first conveyor seat 32, a second drive assembly, a second sliding seat 42, a second lifting motor 43, a trimming frame 44, a third drive motor 46, a second conveyor seat 45, and a cutting wheel 47. The first drive assembly is symmetrically arranged at the top of the work box 2. The first drive assembly is slidably mounted on the first sliding seat 34. The first lifting motor 33 is fixed to the bottom of the first sliding seat 34. The first conveyor seat 32 is fixedly connected to the first lifting motor 33. The first conveyor seat 32 is drivenly connected to the second conveyor roller 321. The second conveyor roller 321 abuts against the upper surface of the film material.

[0023] Two drive slots 4 are symmetrically arranged at the bottom of the working box 2. A second drive assembly is installed in the drive slot 4. A second sliding seat 42 is slidably arranged on the second drive assembly. A second lifting motor 43 is fixed on the second sliding seat 42. A trimming frame 44 is fixedly connected to the second lifting motor 43. A second conveying seat 45 is fixed to the top of the trimming frame 44. A third conveying roller 451 is drivenly connected to the second conveying seat 45. The third conveying roller 451 abuts against the lower surface of the film material. A third drive motor 46 is installed on one side of the trimming frame 44. A cutting wheel 47 is drivenly connected to the output shaft of the third drive motor 46 for trimming the film material.

[0024] With the above structure, the first sliding seat 34 is driven to move forward or backward automatically by the first driving component, and the second sliding seat 42 is driven to move forward or backward automatically by the second driving component. At the same time, the moving direction and moving length of the first sliding seat 34 and the second sliding seat 42 are synchronized, which is beneficial for automatically cutting the cutting wheel 47, and can also cut the film material to different widths as needed; thus, it is more practical.

[0025] The second conveying roller 321 and the third conveying roller 451 move to the preset position. When the film material is conveyed to the trimming mechanism, the first lifting motor 33 descends and the second lifting motor 43 rises. When the film material is cut, since the height of the cutting wheel 47 is higher than the height of the third conveying roller 451, the cutting wheel 47 cuts the film material upward. This allows the second conveying roller 321 above the film material and the third conveying roller 451 below the film material to limit and guide the film material in the vertical direction during trimming. They abut against and press against both sides of the film material at the cutting point to prevent it from curling outward or inward at the cutting point. This helps to improve the trimming quality of the film material, and the automatic trimming has high automation efficiency.

[0026] Specifically, such as Figures 1 to 4As shown, the first drive assembly includes a threaded rod 311, a first lead screw 312, and a first drive motor 313. The first drive motors 313 are symmetrically arranged on both sides of the work box 2. The first lead screw 312 is drivenly connected to the output shaft of the first drive motor 313. The threaded rod 311 is fixedly connected above the first lead screw 312. The first sliding seat 34 passes through the first lead screw 312 and has a first connecting part 341 connected to the threaded rod 311, used to drive the first sliding seat 34 to move forward or backward. The second drive assembly includes a first guide rail 411, a second lead screw 412, and a second drive motor 413. The second drive motor 413 is mounted on one side of the drive groove 4. The second lead screw 412 is drivenly connected to the output shaft of the second drive motor 413. The second lead screw 412 is connected to the second sliding seat 42, and the second sliding seat 42 is slidably arranged on the first guide rail 411.

[0027] With the above structure, the first sliding seat 34 is driven to move forward or backward automatically by the first driving component, and the second sliding seat 42 is driven to move forward or backward automatically by the second driving component. At the same time, the moving direction and moving length of the first sliding seat 34 and the second sliding seat 42 are synchronized, which is beneficial to synchronously drive the second conveying roller 321 and the third conveying roller 451 to limit the vertical direction of the film material during edge trimming, resulting in better edge trimming effect and greatly improved edge trimming quality.

[0028] like Figures 1 to 4 As shown, the bottom center of the working box 2 also has a mounting base 51, on which a fourth conveying roller 52 is driven. By adding a fourth conveying roller 52 for support and conveying at the center end of the film material, it is beneficial to provide high support for the center position of the film material during conveying, preventing the film material from drooping downwards at the center position during edge trimming, which would affect the edge trimming quality, thus greatly improving the edge trimming quality.

[0029] like Figures 1 to 4 As shown, the work box 2 has a top plate 61, on which symmetrically arranged measuring frames 62 are mounted. Each measuring frame 62 has a scale surface 63. A first through hole 64, co-located with the second sliding seat 42, is opened on the top plate 61. A second connecting part 65 is fixed to the first connecting part 341, and the second connecting part 65 has a pointing part 651. The second connecting part 65 passes through the first through hole 64, and the bottom of the carton rests against the scale surface 63. By setting the scale surface 63, and simultaneously allowing the pointing part 651 to move forward or backward as the first sliding seat 34 moves forward or backward, it facilitates real-time observation of the width of the film edge, making observation more convenient.

[0030] like Figures 1 to 4As shown, a control box 7 is installed on one side of the work box 2 for controlling the operation of the device. By setting up the control box 7, the operation of the components inside the work box 2 is driven by the operator manipulating the control box 7.

[0031] like Figures 1 to 4 As shown, the bottom of the work box 2 has support feet 8. By setting support feet 8, it is beneficial to prevent the work box 2 from shaking and moving, and the structure is stable and reliable.

[0032] 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.

[0033] 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.
