[0002] The current existing technology usually includes a pulling roller, a slitting knife, a slitting frame, a feed roller, and a machine body. The pulling roller is connected to the machine body, the slitting knife and the slitting frame are an integrated structure, the slitting frame is welded to the machine body, and the feed roller is movably engaged with the machine body. The plastic film can be clamped by the clamping block on the clamping block, and the pulling generated by the plastic film on the clamping block on the feed roller can drive the clamping block to unfold along the guide frame, so that the extension surface can cooperate with the pulling roller to pull the last plastic film. The thrust generated by the plastic film on the knife body can make the knife body swing backward along the middle solid ring with the cooperation of the linkage rod, and the pulling generated by the rebound sheet on the linkage rod can make the linkage rod drive the knife body to swing forward to cut the plastic film.

[0026] It should be noted that, in this embodiment, while the film is rolling on the outer wall of the cutting roller 141, the blade 167 is used to cut the gap between the cutting rollers 141, so that the film is divided into strips, and then the driving motor 12 drives the partial winding roller 13 to rotate in advance, so that the outer wall of the partial winding roller 13 drives the film to be wound around the outer wall of the partial winding roller 13, and at the same time, the partition plate 131 is used to limit and separate the stripped film.

[0027] A card slot 161 is provided at the top left side of the inner side of the installation box 16, and a blade holder 162 is slidably connected to the inner side of the top of the installation box 16. A blade 167 is fixedly installed at one end of the outer wall of the blade holder 162 on the left side, and a sliding slot 1621 is provided on the outer wall of the right side of the blade holder 162. A sliding rod 1631 is slidably connected to the inner side of the sliding slot 1621. One end of the sliding rod 1631 is located at the inner side of the top of the installation box 16 and is fixedly connected to the limit plate 163. The outer wall of the sliding rod 1631 is movably sleeved and there is a No. 1 spring 1632 located on one side of the limit plate 163. An extrusion groove 166 is provided at the bottom inside the top of the installation box 16, and a No. 2 spring 164 is fixedly installed at the bottom inside the inner side of the extrusion groove 166. A push plate 165 is fixedly installed at one end of the top of the No. 2 spring 164 and located at the inner side of the top of the installation box 16.

[0028] It should be noted that, in this embodiment, when replacing and disassembling the blade holder 162, it is only necessary to press the blade holder 162 so that the bottom of the blade holder 162 squeezes the push plate 165, thereby causing the push plate 165 to push the No. 2 spring 164 to squeeze, so that the groove at the top of the blade holder 162 is separated from the inner side of the outer wall of the card slot 161, and then push the blade holder 162 so that the blade holder 162 squeezes the slide bar 1631 so that the slide bar 1631 is slidably connected to the inner side of the sliding groove 1621, and then the blade holder 162 is lifted so that the blade holder 162 is taken out of the inner side of the installation box 16, thereby achieving the purpose of disassembly.

[0029] A film roller 111 is rotatably connected to the right side of the inner side of the mounting frame 11, a tension detector 192 is fixedly installed in the middle of the inner outer wall of the mounting frame 11, a tension detection roller 19 is movably sleeved on the inner side of the tension detector 192, a tension controller 191 is fixedly installed at one end of the bottom of the tension detector 192, the outer wall of the inner side of the mounting frame 11 and located on the left side of the tension controller 191 is rotatably connected to the second auxiliary roller 18, and the outer wall of the inner side of the mounting frame 11 and located on the right side of the tension controller 191 is rotatably connected to the number one auxiliary roller 17.

[0030] It should be noted that, in this embodiment, before the film is striped, the film on the outer wall of the film roller 111 is extended from the upper surface of the No. 1 auxiliary roller 17 to the upper surface of the tension detection roller 19, passes through the lower surface of the No. 2 auxiliary roller 18, and is pulled to the upper surface of the cutting roller 141 for striping, and is wound from the bottom of the partial winding roller 13 to the outer wall of the partial winding roller 13, and then the drive motor 12 is started to drive the film to be striped quickly, and then the tension detection roller 19 is tension-detected by the tension detector 192, and then the tension controller 191 is used to adjust according to the preset parameters through the tension detector 192 to achieve the desired tension control effect, avoid material stretching, breakage or accumulation due to uneven tension, thereby ensuring the continuity and stability of the production process.

[0031] The working principle of the present invention is as follows: before the film is slit, the film on the outer wall of the film roller 111 is extended from the upper surface of the No. 1 auxiliary roller 17 to the upper surface of the tension detection roller 19, passes through the lower surface of the No. 2 auxiliary roller 18, and is pulled to the upper surface of the cutting roller 141 for slit, and is wound from the bottom of the partial winding roller 13 to the outer wall of the partial winding roller 13, and then the drive motor 12 is started to drive the film to be slit quickly, and then the tension of the tension detection roller 19 is detected by the tension detector 192, and then the tension controller 191 is used to adjust according to the preset parameters through the tension detector 192 to achieve the desired tension control effect, avoid material stretching, breakage or accumulation due to uneven tension, thereby ensuring the continuity and stability of the production process.

[0032] While the film is rolling on the outer wall of the cutting roller 141, the blade 167 is used to cut the gap between the cutting rollers 141, so that the film is divided into strips. Then, the driving motor 12 drives the partial winding roller 13 to rotate in advance, so that the outer wall of the partial winding roller 13 drives the film to be wound around the outer wall of the partial winding roller 13. At the same time, the partition plate 131 is used to limit and separate the stripped film.

[0033] When replacing and disassembling the blade holder 162, it is only necessary to press the blade holder 162 so that the bottom of the blade holder 162 squeezes the push plate 165, thereby causing the push plate 165 to push the No. 2 spring 164 to squeeze, so that the groove at the top of the blade holder 162 is separated from the inner side of the outer wall of the card slot 161, and then push the blade holder 162 so that the blade holder 162 squeezes the slide bar 1631 so that the slide bar 1631 is slidably connected to the inner side of the sliding groove 1621, and then the blade holder 162 is lifted so that the blade holder 162 is taken out of the inner side of the installation box 16, thereby achieving the purpose of disassembly.
