Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Example: Please refer to Figures 1-4This embodiment provides an automatic film-tearing device for metal sheet processing, including a frame 1, a fixed back plate 2, a metal sheet limiting mechanism, an upper tearing assembly, and a lower tearing assembly. The fixed back plate 2 is fixedly connected to the frame 1, and the metal sheet limiting mechanism is installed on the fixed back plate 2. The metal sheet limiting mechanism includes two roller frames 4 fixedly connected to the front end of the fixed back plate 2, and fixed conveying rollers 3 are rotatably connected inside the roller frames 4. The two fixed conveying rollers 3 are located on the same horizontal plane, and both are directly above the two fixed conveying rollers 3. A limiting conveyor roller 5 is provided. A first through groove 201 is longitudinally opened on the fixed back plate 2 at the limiting conveyor roller 5. One end of the limiting conveyor roller 5 is rotatably connected to a first slide block 501, which is slidably installed in the first through groove 201. A first adjusting component 6 is installed between the two first slide blocks 501 on the fixed back plate 2. The hardware sheet limiting mechanism also includes a side limiting component 7 for laterally limiting the hardware sheet. An upper tearing component is arranged above the limiting conveyor roller 5 for winding up the upper surface of the hardware sheet. The plastic film is peeled off by a lower tearing assembly located below the fixed conveyor roller 3. This assembly is used to roll up the plastic film on the lower surface of the metal sheet. In use, the metal sheet to be peeled is placed at the upper limit of the metal sheet limiting mechanism. The metal sheet is made of aluminum strip or other strip material. By placing the metal sheet on top of the two fixed conveyor rollers 3 and simultaneously adjusting the height of the two limiting conveyor rollers 5 longitudinally via the first adjusting assembly 6, the limiting conveyor rollers 5 are guided and slid within the first through groove 201 via the first slide block 501. This improves the stability of the moving adjustment of the limiting conveyor rollers 5. The limiting conveyor rollers 5 are then pressed against the top of the metal sheet to be peeled, limiting the position of the metal sheet. The metal sheet is conveyed between the fixed conveyor roller 3 and the limiting conveyor rollers 5, improving the stability of the conveying process. During the conveying of the metal sheet, the upper tearing assembly automatically peels and rolls up the plastic film on the upper surface of the metal sheet, and the lower tearing assembly automatically peels and rolls up the plastic film on the lower surface of the metal sheet. This achieves fully automated peeling with high stability and efficiency, reducing manual labor.

[0019] In this embodiment, as Figure 1 As shown, the upper tearing assembly includes an upper geared motor 8 and an upper tearing rod 9. The upper geared motor 8 is fixedly installed on the top of the frame 1. One end of the upper tearing rod 9 is fixedly connected to the output end of the geared motor 8. The plastic film on the upper surface of the metal sheet is adhered to the upper tearing rod 9. The upper geared motor 8 drives the upper tearing rod 9 to rotate, gradually winding and rolling the plastic film on the upper surface of the metal sheet onto the upper tearing rod 9, thereby realizing the function of tearing off the plastic film on the upper surface of the metal sheet.

[0020] In this embodiment, as Figure 1As shown, the lower tearing assembly includes a lower reduction motor 10 and a lower tearing rod 11. The lower reduction motor 10 is fixedly installed on the side wall of the frame 1. One end of the lower tearing rod 11 is fixedly connected to the output end of the lower reduction motor 10. The plastic film on the lower surface of the metal sheet is adhered to the lower tearing rod 11. The lower reduction motor 10 drives the lower tearing rod 11 to rotate, gradually wrapping and rolling the plastic film on the lower surface of the metal sheet onto the lower tearing rod 11, thereby achieving the function of tearing off the plastic film on the lower surface of the metal sheet.

[0021] In this embodiment, as Figure 3 As shown, the first adjusting assembly 6 includes a first threaded rod 603, a connecting plate 601, a first threaded sleeve 602, and a first knob 605. The first threaded rod 603 is longitudinally disposed on the back of the fixed back plate 2. Both ends of the first threaded rod 603 are fixed to the fixed back plate 2 via first bearing seats 604. The connecting plate 601 is fixedly connected between two first slide blocks 501. The first threaded sleeve 602 is fixedly connected to the connecting plate 601 and threadedly connected to the outside of the first threaded rod 603. The top of 603 extends to the outside of the fixed back plate 2 and is fixedly connected to the first knob 605. By rotating the first knob 605, the first threaded rod 603 is driven to rotate, so that the first threaded sleeve 602 moves axially along the first threaded rod 603. This causes the two first slide blocks 501 to slide in the first through groove 201 of the fixed back plate 2 through the connecting plate 601, thereby realizing the height adjustment function of the limiting conveying roller 5. Under the cooperation of the limiting conveying roller 5 and the fixed conveying roller 3, it can convey hardware sheets of different thicknesses, which is highly practical.

[0022] In this embodiment, as Figure 4 As shown, the side limiting assembly 7 includes a side guide roller 701, a mounting plate 702, a second slide block 706, and a second adjusting assembly. The side guide roller 701 is arranged longitudinally, and the height of the bottom end of the side guide roller 701 is lower than the height of the fixed conveyor roller 3. The mounting plate 702 is fixedly connected to the front end of the fixed back plate 2. A second through groove 703 is provided on the mounting plate 702 along the axial direction of the fixed conveyor roller 3. The second slide block 706 is rotatably connected to the top end of the side guide roller 701 and is slidably installed inside the second through groove 703. The second adjusting assembly is installed on the mounting plate 702 for driving... The second slide block 706 moves along the second through groove 703. The second adjusting component can drive the second slide block 706 to move within the second through groove 703 of the mounting plate 702. The second slide block 706 drives the side stop roller 701 to adjust its position. The side stop roller 701 blocks the side of the conveyed hardware sheet, which is used for lateral limiting of the hardware sheet and prevents the hardware sheet from shaking or deviating during conveying. The adjustable side stop roller 701 is suitable for limiting hardware sheets of different widths, and has high practicality.

[0023] In this embodiment, as Figure 4 As shown, the second adjustment assembly includes a second threaded rod 704, a second threaded sleeve 707, and a second knob 708. The second threaded rod 704 is disposed above the second through groove 703. Both ends of the second threaded rod 704 are fixedly mounted to the mounting plate 702 via second bearing seats 705. The second threaded sleeve 707 is fixedly connected to the top of the second slide block 706 and threadedly connected to the outside of the second threaded rod 704. One end of the second threaded rod 704 extends to the outside of the mounting plate 702 and is fixedly connected to the second knob 708. By rotating the second knob 708, the second threaded rod 704 is rotated, causing the second threaded sleeve 707 to move axially along the second threaded rod 704. This causes the second slide block 706 to move within the second through groove 703 via the second threaded sleeve 707, thereby adjusting the position of the side guide roller 701 via the second slide block 706.

[0024] In this embodiment, as Figure 2 As shown, an upper infrared detection fiber 12 is fixedly connected to the front end of the fixed back plate 2. The upper infrared detection fiber 12 is located at the plastic film winding path on the upper surface of the metal sheet. A lower infrared detection fiber 13 is also fixedly connected to the front end of the fixed back plate 2. The lower infrared detection fiber 13 is located at the plastic film winding path on the lower surface of the metal sheet. The upper infrared detection fiber 12 is used to detect whether there is plastic film at the plastic film winding path on the upper surface of the metal sheet, and to determine whether the plastic film on the upper surface is broken or not properly wound. The lower infrared detection fiber 13 is used to detect whether there is plastic film at the plastic film winding path on the lower surface of the metal sheet, and to determine whether the plastic film on the lower surface is broken or not properly wound.

[0025] The control method of this utility model is controlled by the controller of the automatic film-tearing device for metal sheet processing. The upper reduction motor 8, the lower reduction motor 10, the upper infrared detection fiber 12, and the lower infrared detection fiber 13 are electrically connected to the controller. The control program of the controller can be implemented by those skilled in the art through simple programming. Therefore, the control method and circuit connection will not be explained in detail in this utility model.

[0026] Working principle: In use, the metal sheet to be peeled is placed at the upper limit of the metal sheet limiting mechanism. By placing the metal sheet on top of the two fixed conveyor rollers 3, rotating the first knob 605 drives the first threaded rod 603 to rotate, causing the first threaded sleeve 602 to move axially along the first threaded rod 603. This, in turn, drives the two first slide blocks 501 to slide within the first through groove 201 of the fixed back plate 2 via the connecting plate 601, thereby achieving the height adjustment function of the limiting conveyor roller 5. The limiting conveyor roller 5 is moved and pressed against the top of the metal sheet to be peeled, limiting the position of the metal sheet. Then, rotating the second knob 708 drives the second threaded rod 704 to rotate, causing the second threaded sleeve 707 to move axially along the second threaded rod 704. This second threaded sleeve 707 drives the second slide block 706 to move within the second through groove 703, and the second slide block 706 drives the side stop roller 70. 1. Adjust the position so that the side guide roller 701 blocks the side of the conveyed metal sheet for lateral limiting of the metal sheet, preventing the metal sheet from shaking or deviating during conveying. Then, the plastic film on the upper surface of the metal sheet is wrapped around one of the limiting conveying rollers 5 and adhered to the upper tearing rod 9. The plastic film on the lower surface of the metal sheet is wrapped around one of the fixed conveying rollers 3 and adhered to the lower tearing rod 11. When the metal sheet is conveyed, the upper tearing rod 9 is rotated by the upper reduction motor 8, which gradually wraps and rolls the plastic film on the upper surface of the metal sheet onto the upper tearing rod 9, thus removing the plastic film from the upper surface of the metal sheet. The lower tearing rod 11 is rotated by the lower reduction motor 10, which gradually wraps and rolls the plastic film on the lower surface of the metal sheet onto the lower tearing rod 11, thus removing the plastic film from the lower surface of the metal sheet. This fully automated film tearing process is highly stable and efficient, reducing manual labor.

[0027] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
