Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a slitting device used for film production. Background Art

[0002] With the growing development of the film industry, various plastic films have emerged one after another. They have excellent chemical stability, heat sealing, water resistance and moisture resistance, bright luster and soft texture, and are widely used in the packaging industry and laminating industry.

[0003] In the production process of film, slitting machines are mainly used to cut the film. When using traditional film slitting machines, since the cutting knife of the slitting machine is generally fixedly installed on the knife clamp, the slitting machine can only cut the film into sheets of fixed specifications, and the applicability is poor.

[0004] To solve the above problems, the existing slitting devices are generally equipped with multiple cutters that can be adjusted horizontally, so as to be able to cut films of different widths and cut into multiple strips at a time. However, precisely because the existing cutters can move horizontally, they may become loose, change their positions left and right, and shift during long-term work, resulting in inaccurate cutting width. Although the personnel have come up with a countermeasure, after adjusting the position, the moving end of the cutter is fixed with bolts or screws, but this method takes a certain amount of time to fix when there are many cutters, and the screws need to be removed one by one for the next adjustment, affecting the overall production efficiency.

The push rod 4 can push the card plate 8, and multiple cutters 11 are correspondingly arranged on the rotating ring 9. The cutter 11 follows the rotating ring 9 to rotate and can cut the film; the limiting assembly includes a card block 16, and the inner side wall of each rotating ring 9 is provided with a movable groove 15 along the circumferential direction. The card block 16 is arranged on the fixed shaft 10 and corresponds to the position of the movable groove 15, and the card block 16 is slidably connected with the movable groove 15; sliders 13 are arranged on the bottom surfaces of both sides of the movable plate 5, and the support plate 6 is provided with a slide groove 17 corresponding to the position of the slider 13, and the slider 13 is slidably connected with the slide groove 17; a tension spring 14 is connected between the edge of the support plate 6 and the bottom of the card plate 8; the shape of the card plate 8 is L-shaped, and the push rod 4 pushes the card plate 8 to be stuck in the L-shaped right angle; a scale mark 2 is arranged on the upper surface of the support plate 6 and corresponds to the position of each push rod 4.

[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the instruction manual Figure 1-3 It can be known that when the utility model is working, since a plurality of rotating rings 9 and cutters 11 are evenly arranged on the fixed shaft 10, the corresponding cutter 11 can be selected according to the demand. Specifically, the push rod 4 corresponding to the corresponding cutter 11 is rotated to the side away from the card plate 8. The push rod 4 is rotatably connected with the upper surface of the movable plate 5 through the rotating shaft 3, so it is easy for personnel to rotate, convenient and fast. After adjusting the push rod 4, the cylinder 7 is started, and the telescopic end of the cylinder 7 is extended to drive the movable plate 5 to move, thereby driving the push rod 4 above to move. The side of the push rod 4 corresponding to the card plate 8 is in contact with the card plate 8, and starts to push the card plate 8 on the rotating ring 9, so that the card plate 8 and the rotating ring 9 are rotated. Figure 2 and Figure 3For example, the rotating ring 9, the clamping plate 8 and the cutter 11 are rotated clockwise so that the cutter 11 can cut the film. Here, the rotating ring 9 and the fixed shaft 10 can only rotate 30 degrees through the limit assembly, that is, Figure 2 Towards Figure 3 The push rod 4 then presses the card plate 8 tightly and fixes it, and the cutter 11 cannot move. The film is conveyed on the conveying roller 12 between the pair of plates 1, and the cutter 11 cuts it. During the operation of the cylinder 7, the push rod 4 that rotates to the side away from the card plate 8 cannot contact the card plate 8, so it cannot rotate. The cutter 11 is in Figure 2 The film cannot be cut if it is in a horizontal state.

[0023] Among them, the limiting assembly includes a clamping block 16, and a movable groove 15 is opened along the circumferential direction on the inner wall of each rotating ring 9. The clamping block 16 is arranged on the fixed shaft 10 and corresponds to the position of the movable groove 15. The clamping block 16 is slidably connected with the movable groove 15. The arc length of the movable groove 15 determines the rotation range of the rotating ring 9. Here, the rotating ring 9 is rotated 30 degrees.

[0024] Among them, sliders 13 are arranged on the bottom surfaces of both sides of the moving plate 5, and sliding grooves 17 are opened at the positions of the supporting plate 6 corresponding to the sliders 13. The sliders 13 are slidably connected with the sliding grooves 17 to ensure the stability of the moving plate 5 when moving.

[0025] Among them, a tension spring 14 is connected between the edge of the support plate 6 and the bottom of the card plate 8. When the push rod 4 does not squeeze the card plate 8, the tension spring 14 will cause the rotating ring 9 to rotate counterclockwise, so that the cutter 11 is in a lifted state and does not affect the normal transportation of the film.

[0026] The shape of the clamping plate 8 is L-shaped, and the push rod 4 can push the clamping plate 8 into the right angle of the L-shape, and the clamping method is simple and convenient.

[0027] Among them, a scale mark 2 is set on the upper surface of the support plate 6 and corresponds to the position of each push rod 4, which is convenient for personnel to quickly identify the corresponding position of the push rod 4 and accurately select the push rod 4 at the position that needs to be cut.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
