[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] In modern industrial production, slitting machines are widely used in packaging, printing, textiles, and other fields. Currently available slitting machines have significant safety defects when manually adjusted. Operators need to be in close contact with the slitting blades during adjustment, making them highly susceptible to accidental contact due to negligence, fatigue, or improper operation, leading to personal injury. This is especially true in multi-shift continuous production scenarios, where prolonged high-intensity work further increases the probability of operational errors, making the safety hazard particularly prominent. Therefore, this utility model proposes an adjustable strip slitting device. Please refer to the attached document. Figure 1 -Appendix Figure 5 The device includes a main body 1, which includes a detachable component 9 and a drive structure 10 connected to the detachable component 9. The detachable component 9 includes a slide rod 91 and a fastening plate 95. A first cutting blade 92 and a second cutting blade 93 are respectively mounted on the slide rod 91. The first cutting blade 92 and the second cutting blade 93 have the same structure. A connecting frame 94 is provided on both the first cutting blade 92 and the second cutting blade 93. Bolts are provided between the connecting frame 94 and the fastening plate 95 to facilitate the disassembly of the first cutting blade 92 and the second cutting blade 93. The unloading and drive structure 10 includes a motor 101, a screw 102 mounted on the motor 101, two fastening plates 95 mounted on the screw 102, electromagnetic clutches 103 mounted on both sides of the screw 102, bevel gear 104 mounted on both sides of the screw 102, bevel gear 2 105 meshing on bevel gear 104, a rotating shaft mounted on bevel gear 2 105, and protective plates 106 mounted on both sides of the rotating shaft. The number of protective plates 106 is set to four to facilitate the protection of operators during the cutting process.

[0024] Example 1: A workbench 2 is provided in the middle of the main body 1 of the device. Support columns 3 are provided at the four corners of the bottom of the workbench 2. Anti-slip pads are provided at the bottom of the support columns 3. A transmission groove 4 is provided in the middle of the workbench 2. A material belt body 5 is provided inside the transmission groove 4. Multiple collection chambers 6 are provided on the transmission groove 4. A holding box 7 is provided at the bottom of the workbench 2. A pull ring 71 is provided on the outside of the holding box 7.

[0025] Specifically, the support column 3 and anti-slip pad are provided to support the main body 1 of the device. After processing, dust and debris enter the collection chamber 6. The container 7 and pull ring 71 are provided to facilitate the cleaning of debris and dust. The transmission groove 4 is provided to facilitate the processing of the material belt body 5.

[0026] Example 2: Fixing blocks 8 are provided on both sides of the workbench 2, and a slide bar 91 is provided between the two fixing blocks 8. A controller is provided in front of one of the support columns 3. The controller is electrically connected to the motor 101 and the electromagnetic clutch 103 respectively.

[0027] Specifically, the new type uses a motor 101 to drive the first cutting blade 92 and the second cutting blade 93 to move relative to each other or towards each other, thereby adjusting the cutting distance between the first cutting blade 92 and the second cutting blade 93. At the same time, bevel gear 104 and bevel gear 2 105 mesh and rotate, driving the protective plate 106 on the rotating shaft to rotate, thereby protecting the workers.

[0028] Specifically, the first cutting blade 92 and the second cutting blade 93 are disassembled by bolts through the fastening plate 95 and the connecting frame 94, thereby enabling the disassembly and use of the first cutting blade 92 and the second cutting blade 93.

[0029] Working principle:

[0030] First, the main body 1 of the device is supported on the ground by the support column 3 and the anti-slip pad. When the material belt body 5 needs to be processed, the material belt body 5 is placed inside the transmission groove 4 for processing. During the processing, dust and debris enter the collection chamber 6. When the first cutting blade 92 and the second cutting blade 93 need to be used, the first cutting blade 92 and the second cutting blade 93 are fastened together by bolts through the fastening plate 95 and the connecting frame 94. At the same time, the two electromagnetic clutches 103 are opened, and the controller starts the motor 101 to drive the first cutting blade 92 and the second cutting blade 93 to move relative to each other or towards each other, thereby adjusting the cutting distance of the first cutting blade 92 and the second cutting blade 93. At the same time, the bevel gear 104 and the bevel gear 2 105 mesh and rotate, driving the protective plate 106 on the rotating shaft to rotate, thereby protecting the workers. When the protective plate 106 is not needed, the two electromagnetic clutches 103 are closed, and the motor 101 only drives the first cutting blade 92 and the second cutting blade 93 to move. At this point, the entire workflow is completed.
