Description

Technical Field

[0001] The utility model relates to the field of covering film cutting, in particular to a covering film edge trimming device. Background Art

[0002] Covering film generally refers to a thin film layer covering a surface or material for the purpose of providing protection, improving surface properties or achieving specific functions, including wrapping film and stretch film.

[0003] The present production process of stretch film usually ends with a take-up drum to reel the stretch film, and when the reeling is completed, the stretch film needs to be cut. However, when cutting the existing stretch film, due to the large toughness of the stretch film and the lack of a fixing device for the stretch film, the cutter will move with the stretch film during the cutting process, so that the cutter cannot completely fit the stretch film during the entire cutting process, resulting in intermittent cuts, which will result in the stretch film not being completely cut, and the staff needs to tear the stretch film or cut it multiple times, which greatly reduces the production efficiency of the stretch film and causes a certain degree of waste of the stretch film, thereby increasing the production cost.

[0004] Therefore, in view of the problem that the existing cutter does not have a fixing device for the stretch film during the cutting process, resulting in intermittent cutting and inability to completely cut the stretch film, a covering film trimming device that solves the above problem is needed.

[0029] Example 1:

[0030] A device for trimming a covering film comprises a mounting frame 1, a movable plate 2 being slidably connected to the top right end of the mounting frame 1, the movable plate 2 being able to press and fix the covering film located on its bottom side, thereby preventing the cutter from driving the covering film when cutting the covering film, a screw 3 being provided at the front top end of the movable plate 2, the screw 3 being able to move with the movable plate 2, thereby enabling the movable plate 2 to press and fix the covering film, a movable groove being provided at the top right end of the movable plate 2, the movable groove providing a position for the movement of the cutter, and a screw 26 being rotatably connected in the movable groove , screw 2 6 can move with moving block 7, so that moving block 7 moves with cutter, the outer wall of screw 2 6 is threadedly connected with moving block 7, the rear side of moving plate 2 is installed with motor 2 5, motor 2 5 can drive screw 2 6 to rotate, and a pad 8 is provided on the bottom side of moving plate 2, which can protect the cutter when the cutter cuts the covering film and improve the cutting efficiency of the cutter on the covering film. The pad 8 is fixedly connected to the mounting frame 1, and a groove is provided at the middle end of the top side of the pad 8, which allows the staff to intuitively see the cutting position of the cutter. The top of the movable plate 2 is threaded with a screw rod 3. A motor 4 is mounted on the top side of the screw rod 3, which can drive the screw rod 3 to rotate. Both the top and bottom sides of the screw rod 3 are rotatably connected to the mounting frame 1. The driving end of the motor 4 is connected to the screw rod 3, while the non-driving end of the motor 4 is connected to the mounting frame 1. A guide rod 14 is slidably connected to the rear end of the top side of the movable plate 2. The guide rod 14 can limit the movement of the movable plate 2. Both the top and bottom sides of the guide rod 14 are fixedly connected to the mounting frame 1. A rotating rod is rotatably connected to the middle end of the mounting frame 1. A roller is fixedly connected to the outer wall of the rotating rod. The roller can limit the position of the covering film, so that the height of the unwound covering film is closer to the pad 8. The bottom side of the movable block 7 has a knife groove for mounting a cutter. The cutter is mounted in the knife groove and connected to the movable block 7 via multiple bolts. The bolts ensure the stability of the connection between the cutter and the movable block 7. Support legs are fixedly connected to the four corners of the bottom side of the mounting frame 1.

[0031] Example 2:

[0032] As one of the optimized structural designs for Example 1, Figures 1-4As shown, the left rear end of the mounting frame 1 is rotatably connected to the turntable 9. A bidirectional screw 12 is rotatably connected to the turntable 9 at the middle end of the front side of the turntable 9. A motor 3 11 is provided to the right of the bidirectional screw 12. The motor 3 11 can drive the bidirectional screw 12 to rotate, and both the left and right sides of the bidirectional screw 12 are rotatably connected to the turntable 9. The driving end of the motor 3 11 is connected to the bidirectional screw 12, and the non-driving end of the motor 3 11 is connected to the turntable 9. Two clamping blocks 10 are threadedly connected to the outer wall of the bidirectional screw 12. Rotation of the bidirectional screw 12 can cause the two clamping blocks 10 to clamp and fix the winding drum used to wind the covering film. The two clamping blocks 10 are slidably connected to the front side of the turntable 9. A motor 4 13 is installed at the left rear end of the mounting frame 1. The motor 4 13 can drive the turntable 9 to rotate, and the driving end of the motor 4 13 is connected to the turntable 9.

[0033] Working principle: First, make the two clamping blocks 10 fit together, and put the winding drum on the two clamping blocks 10, and use the motor 3 11 to drive the bidirectional screw 12 to rotate, so that the two clamping blocks 10 are separated, so that the clamping blocks 10 fix the winding drum from the inside of the winding drum, and then introduce the covering film to be rolled from the right side of the mounting frame 1, and make the covering film be located between the moving plate 2 and the pad 8, and then pass the covering film from the bottom side of the drum and wrap the covering film on the outer wall of the winding drum, and use the motor 4 13 to drive the turntable 9 to rotate, so that the turntable 9 rotates with the winding drum to adjust the covering film. The film is wound up. When the winding is appropriate, the covering film needs to be cut. The motor 4 drives the screw 3 to rotate. The screw 3 rotates and moves the movable plate 2 downward, and fits with the pad 8. While pressing and fixing the covering film, the cutter will also pierce the covering film, thereby facilitating the cutting of the covering film and avoiding displacement of the covering film during cutting, so that the cutter cannot completely cut the covering film. The motor 2 5 then drives the screw 2 6 to rotate. The screw 2 6 rotates and moves the movable block 7, so that the movable block 7 moves with the cutter to cut the covering film.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
