Description

Technical Field

[0001] The utility model relates to the technical field of winding film cutting, in particular to a cutting device for winding film production. Background Technique

[0002] The winding film, also known as stretch film and heat shrinkable film, was originally made of PVC as the base material and DOA as the plasticizer, which also served as a self-adhesive agent to produce PVC winding film in China; the winding film has different specifications according to different widths. Therefore, during the production of the winding film, a cutting device is required to achieve cutting operations of different widths.

[0003] During the application of the existing cutting device for winding film production, the tool holders used inside it are mostly fixedly installed by bolts, and the distance between adjacent tool holders cannot be adaptively adjusted according to the different widths of the winding film to be processed. When it is necessary to process winding films of other widths, the tool holders need to be disassembled and reinstalled again, which takes a long time and relatively affects the processing efficiency of the winding film. Summary of the Utility Model

[0028] Embodiment 1: Please refer to Figures 1 to 6 :

[0029] The utility model provides a cutting device for producing winding films, comprising: a cutting support frame 1; a bidirectional screw 2 is installed inside the cutting support frame 1, and seven movable tool holders 3 are connected to the outside of the cutting support frame 1 in an arranged manner. The bidirectional screw 2 is connected to the seven movable tool holders 3; a telescopic frame 4 is connected to the outside of the movable tool holder 3, and the movable tool holder 3 is connected to the adjacent movable tool holder 3 through the telescopic frame 4; a connecting groove 305 is arranged inside the movable tool holder 3, and a cutting knife 6 is installed inside the connecting groove 305. The cutting edge of the cutting knife 6 is inclined; two bolts 5 are threadedly connected to the outside of the movable tool holder 3, and the end of the bolt 5 is in contact with the cutting knife 6; two sliding holes 302 are arranged inside the movable tool holder 3, and two guide rods 101 are arranged outside the cutting support frame 1. The guide rods 101 slidably penetrate through the sliding holes 302 arranged on the movable tool holder 3. According to the different widths of the winding film to be cut, the movable tool holder 3 can be slidably adjusted to change the distance between two adjacent cutting knives 6, and different widths of winding films can be cut through the cutting knife 6, meeting the production and use requirements of the winding film.

[0030] In an embodiment of the present disclosure, two positioning holes 301 are arranged inside one of the movable tool holders 3. The movable tool holder 3 provided with the positioning holes 301 is located in the middle part of the guide rod 101. The positioning holes 301 are communicated with the sliding holes 302. A positioning block 1011 is arranged in the middle part of the guide rod 101. The positioning block 1011 is connected to the positioning holes 301 arranged on the movable tool holder 3. The bidirectional screw 2 is rotatably connected to the cutting support frame 1. A knob 201 is arranged at the end of the bidirectional screw 2. Five of the movable tool holders 3 are provided with through holes 303. The five movable tool holders 3 provided with the through holes 303 are close to the middle part of the guide rod 101. The bidirectional screw 2 movably penetrates through the through holes 303 arranged on the movable tool holder 3. Two of the movable tool holders 3 are provided with threaded holes 304. The two movable tool holders 3 provided with the threaded holes 304 are close to the two ends of the guide rod 101. The bidirectional screw 2 is threadedly connected to the threaded holes 304 arranged on the movable tool holder 3. The telescopic frame 4 is composed of fourteen connecting rods 401 rotatably connected. The telescopic frame 4 is rotatably connected to the seven movable tool holders 3;

[0031] Adopting the above technical solution, the positioning block 1011 cooperates with the positioning holes 301 to fix the movable tool holder 3 located in the middle part of the guide rod 101. Rotate the bidirectional screw 2. The two movable tool holders 3 located at the two ends of the guide rod 101 are driven by the bidirectional screw 2 to move synchronously. The movable tool holder 3 drives the remaining movable tool holders 3 to move synchronously through the telescopic frame 4, so that the distance between two adjacent movable tool holders 3 is equal, ensuring the consistency of the cutting width of the winding film and effectively avoiding the occurrence of the situation that the winding film is cut with different widths. When the bidirectional screw 2 is rotated forward for adjustment, the bidirectional screw 2 drives the movable tool holder 3 to move inward, and the distance between two adjacent cutting knives 6 gradually decreases. When the bidirectional screw 2 is rotated backward for adjustment, the bidirectional screw 2 drives the movable tool holder 3 to move outward, and the distance between two adjacent cutting knives 6 gradually increases, and the operation is more convenient.

[0032] Working principle of this embodiment: The positioning block 1011 cooperates with the positioning hole 301 to fix the movable tool holder 3 located in the middle part of the guide rod 101. According to the different widths of the winding film to be cut, the bidirectional screw 2 is rotated. The bidirectional screw 2 drives the two movable tool holders 3 at both ends of the guide rod 101 to move synchronously. The movable tool holder 3 drives the remaining movable tool holders 3 to move synchronously through the telescopic frame 4, so that the distance between adjacent two movable tool holders 3 is equal, ensuring the consistency of the cutting width of the winding film. When the bidirectional screw 2 is rotated forward for adjustment, the bidirectional screw 2 drives the movable tool holder 3 to move inward, and the distance between adjacent two cutting knives 6 gradually decreases. When the bidirectional screw 2 is rotated reversely for adjustment, the bidirectional screw 2 drives the movable tool holder 3 to move outward, and the distance between adjacent two cutting knives 6 gradually increases. By changing the distance between adjacent two cutting knives 6, the cutting of winding films with different widths is realized by the cutting knives 6, meeting the production and use requirements of the winding film.
