Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a cutting device for an anti-deviation silicone protective film. Background Technology

[0002] Silicone screen protectors are protective films used to protect the screens of electronic products. Because electronic products come in various sizes, silicone screen protectors need to be cut after production, requiring the use of cutting equipment.

[0003] To improve the flatness of silicone protective film after cutting, existing technologies have made many improvements to silicone protective film cutting equipment. For example, patent publication number CN219235385U discloses a silicone protective film cutting device with anti-deviation feature. This device includes a worktable with four clamping screws mounted on its upper end. Limit blocks are mounted on the clamping screws, and guide rods are installed through the limit blocks. The lower ends of the guide rods are fixed to the worktable, and cylinders are fixedly connected to the left and right sides of the upper end of the worktable. The device also includes a first servo motor fixed to the lower side of a lifting plate, with an adjusting screw connected to its output end and a movable plate mounted on the adjusting screw; and a contact post, installed through the interior of the vertical rod, with a flattening roller connected to its lower end. This anti-deviation silicone protective film cutting device allows for easy smoothing of the protective film near the cutter during use, preventing wrinkles near the cutter during cutting and thus avoiding affecting the flatness of the final cut edge.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents describe clamping and fixing the silicone protective film onto a worktable and using a movable cutter to cut it. However, in reality, silicone protective films are typically produced in rolls. When using the cutting equipment described in the aforementioned comparative documents to cut roll silicone protective films, unfolding, flattening, and clamping them is cumbersome, reducing the efficiency of cutting the silicone protective film. Therefore, there is an urgent need in the art to improve the cutting equipment to overcome the shortcomings of the prior art. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figures 1-6 A cutting device for an anti-deviation silicone protective film includes a support base plate 1. Two symmetrical support seats 2 are provided on the upper part of the support base plate 1. An unwinding unit 3 and a winding unit 4 are respectively provided on the two support seats 2. The unwinding unit 3 is used to unwind the film roll 8, and the winding unit 4 is provided with a winding reel 9 for winding after cutting. An anti-deviation unit 5, a tensioning unit 6, and a cutting unit 7 are sequentially arranged between the unwinding unit 3 and the winding unit 4. The anti-deviation unit 5 is used to prevent deviation during unwinding of the protective film, the tensioning unit 6 is used to tension the protective film during unwinding, and the cutting unit... 7 is used for cutting the protective film. Both the unwinding unit 3 and the winding unit 4 include a first fixing plate 11 fixedly installed on the upper part of one end of the support seat 2. A first drive motor 10 is fixedly installed on one side of the first fixing plate 11. A first movable plate 12 adapted to the first fixing plate 11 is slidably connected to the support seat 2. An air shaft 13 passing through the first movable plate 12 is rotatably connected to one side of the first fixing plate 11. The first drive motor 10 drives the air shaft 13 to rotate. The film roll 8 and several winding reels 9 are all sleeved and fixed on the side of the corresponding air shaft 13 to prevent deviation. The shifting unit 5 includes a second fixed plate 15 fixedly installed on the upper part of the bearing base plate 1 and a second movable plate 14 slidably connected to the upper part of the bearing base plate 1. A fixing frame 16 is fixedly installed on the upper part of both the second movable plate 14 and the second fixed plate 15. An anti-deviation roller 17 is rotatably connected inside each fixing frame 16. The tensioning unit 6 includes a third fixed plate 18 fixedly installed on the upper part of the bearing base plate 1 and a third movable plate 19 slidably connected to the upper part of the bearing base plate 1. Several limiting posts 25 are inserted into the upper part of both the third fixed plate 18 and the third movable plate 19. A movable seat 26 is fixedly installed between the upper ends of the 25. A spring 27 is sleeved on the side of the limiting post 25. A tension roller 28 that passes through the other movable seat 26 is rotatably connected to the side of one movable seat 26. The cutting unit 7 includes two fourth fixed plates 20 fixedly installed on the upper part of the bearing base plate 1. A second drive motor 22 is fixedly installed on the side of the fourth fixed plate 20. A rotating shaft 23 with one end fixedly installed to the output end of the second drive motor 22 is rotatably connected between the two fourth fixed plates 20. Several cutting discs 24 for cutting are provided on the side of the rotating shaft 23.

[0032] In this embodiment, the specific implementation is as follows: When the silicone protective film needs to be cut, a roll of film 8 is mounted on the side of the air shaft 13 on the unwinding unit 3. Several take-up reels 9 are fitted onto the side of the air shaft 13 on the take-up unit 4. Gas is introduced into the air shaft 13 to fix the film roll 8 and the take-up reels 9. The silicone protective film passes through the anti-deviation unit 5 and the tensioning unit 6 in sequence, and then is conveyed to the cutting unit 7 to cut the silicone protective film. Each cut silicone protective film is coiled around the side of the corresponding take-up reel 9. Two first drive motors 10 drive two air shafts 13 to rotate, realizing the unwinding and winding of the silicone protective film until the roll of film 8 is cut. The silicone protective film is cut by conveying, which improves the protection of the silicone protective film. For cutting efficiency, when the silicone protective film is conveyed between the two anti-deviation rollers 17, the silicone protective film is positioned between the two anti-deviation rollers 17, which prevents the silicone protective film from shifting. Then, the silicone protective film is conveyed to the tension roller 28, where the silicone protective film exerts a downward pulling force on the tension roller 28. At this time, the moving seat 26 moves downward, and the spring 27 is under pressure, which exerts an upward pushing force on the spring 27, thereby achieving the effect of tensioning the silicone protective film. The limiting post 25 is used to limit the moving seat 26. When the silicone protective film is conveyed to the cutting unit 7, the second drive motor 22 is turned on. The output end of the second drive motor 22 drives the rotating shaft 23 to rotate. When the rotating shaft 23 rotates, it drives several cutting discs 24 to rotate, and the several cutting discs 24 cut the silicone protective film being conveyed.

[0033] Example 2

[0034] Please see Figure 2 and Figure 5 This embodiment includes the above embodiment, and further includes: a third drive motor 29 is fixedly installed on the side of the support 2, a first sliding block 30 is fixedly installed on the lower side of the first movable plate 12, a first sliding groove 31 adapted to the first sliding block 30 is opened on the upper part of the support 2, and a drive screw 32 with one end fixedly installed to the output end of the third drive motor 29 is rotatably connected in the first sliding groove 31, and the drive screw 32 is threadedly connected to the first sliding block 30.

[0035] In this specific embodiment, when installing or replacing the film roll 8 or several winding reels 9, the third drive motor 29 is started. The output end of the third drive motor 29 drives the drive screw 32 to rotate. When the drive screw 32 rotates, it drives the first sliding block 30 to slide in the first sliding groove 31. The first sliding block 30 drives the first movable plate 12 to move. The first movable plate 12 disengages from the air shaft 13, and the gas in the air shaft 13 is discharged. This allows the film roll 8 or several winding reels 9 to be installed or disassembled, which is convenient for installing or disassembling the film roll 8 or winding reels 9. Furthermore, since one end of the air shaft 13 passes through the first movable plate 12, it is possible to install and cut film rolls 8 of different widths, thereby improving the applicability of the cutting device.

[0036] Example 3

[0037] Please see Figure 4 This embodiment includes all the above embodiments, and further includes: a second sliding block 33 is fixedly installed between the lower sides of the second movable plate 14 and the third movable plate 19; a second sliding groove 34 adapted to the second sliding block 33 is opened on the upper part of the bearing base plate 1; an adjusting threaded rod 35 is rotatably connected through one side of the bearing base plate 1, with one end extending into the second sliding groove 34; the adjusting threaded rod 35 is threadedly connected to the second sliding block 33; and a limit nut 36 is threadedly connected to the side of the adjusting threaded rod 35.

[0038] In this embodiment, the following specific implementation method is used: By rotating the adjusting threaded rod 35, the second sliding block 33 is driven to slide in the second sliding groove 34. The second sliding block 33 drives the second movable plate 14 and the third movable plate 19 to move, thereby adjusting the distance between the two anti-deviation rollers 17 and the distance between the third fixed plate 18 and the third movable plate 19. This method can prevent the silicone protective film of different widths from shifting and can also tighten it, thus improving the applicability of the cutting device.

[0039] Example 4

[0041] In this embodiment, the specific implementation method is as follows: If it is necessary to cut the silicone protective film into different widths, the sliding ring 37 slides on the side of the rotating shaft 23 to adjust the spacing between each cutting disc 24. At the same time, the positioning bolt 39 is tightened, and one end of the positioning bolt 39 is pressed against the bottom of the limiting groove 38 to limit and fix the position of the cutting disc 24. This allows the rolled film roll 8 to be cut into different widths, further improving the applicability of the cutting device.
