Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a cutting device for a slitting machine. Background Technology
[0002] Slitting machines are key equipment in the continuous material processing industry chain, widely used in metal strips (such as steel plates and copper foils), polymer materials (such as plastic films and rubber strips), papermaking and printing (such as rolls of paper and label paper), textiles and non-woven fabrics, and other fields. Their core task is to cut rolls of continuous material into independent units according to a set length, width, or shape (such as slitting steel strip rolls, cutting and rewinding plastic films, and cutting paper to a fixed length).
[0003] Traditional slitting machine cutting devices are commonly used cutting equipment in industrial production, mainly for dividing materials into specified sizes. Slitting machine cutting devices can achieve relatively simple slitting functions. Their advantages lie in their simple structure, ease of operation, and ability to complete material division in a short time. The equipment has a relatively simple structure, its operation is usually straightforward, and it can meet ordinary cutting needs.
[0004] However, traditional cutting components often fail to adequately consider the sliding system design of the cutting tools. While existing cutting tool sliding structures can achieve basic up-and-down movement, they lack effective protection and support. Traditional equipment cutting components typically do not consider the wear and tear caused by external environmental factors during operation. Their relatively simple structure can lead to accelerated wear of the cutting tool components after prolonged use, affecting cutting accuracy and machine lifespan. In particular, the lack of restriction on the cutting tool's movement trajectory can cause instability or irregularity in the sliding motion, resulting in unsatisfactory cutting results. To address these issues, a cutting device for a slitting machine is proposed. Utility Model Content

[0032] Reference Figure 1 and Figure 3 The electric push rod 21 is fixedly connected to a support frame 16 at its bottom, and the support frame 16 is fixedly connected to a fixing plate 22 at its bottom.
[0033] Specifically, the support frame 16 and the support frame 16 fix the electric push rod 21.

[0037] Specifically, the protective shell 15 and the back plate 18 are used to fix the cutting work on top of the conveyor belt 1.
[0038] Reference Figure 4 One end of spring 23 is fixedly connected to the outside of grid block 9, and the other end of spring 23 is fixedly connected to the outside of fixing ring 26.
[0039] Specifically, the spring 23 has grid blocks 9 and fixed rings 26 fixed at both ends, which are used to compress the spring 23 in the grid blocks 9 and fixed rings 26 to buffer and automatically adjust the slide bar 10.
[0040] Reference Figure 1 and Figure 3 A material discharge rack 2 is fixedly connected to the side of the conveyor belt 1 away from the cutting component, and a material box 3 is set directly below the material discharge rack 2.
[0041] Specifically, a discharge rack 2 is fixed on one side of the conveyor belt 1, and the cut materials flow from the discharge rack 2 into the material box 3.
[0042] Working principle: When the material is placed on the conveyor belt 1 and conveyed forward at a constant speed to the automatic clamping assembly, the handle 11 is pulled, which compresses the spring 23 on the outside of the slide rod 10 between the grid block 9 and the fixing ring 26. When the handle 11 is released, the sliding wheel 25 is tightly pressed against the material surface. At the same time, due to the buffering characteristics of the spring 23, it can adapt to uneven material thickness or slight warping. Then, through the meshing of the motor 7 on the base 8 and the two gears 6 on the rotating rod 12, the other rotating rod 12 on the bracket 5 is driven to rotate, and the material is sent to the cutting assembly. After the material is positioned, the cutting assembly starts the cutting action. The output end of the electric push rod 21 pushes the clamping plate 13 to slide back and forth. When the clamping plate 13 is pushed by the electric push rod 21, the protective shell 15, the back plate 18 and the slide rod 14 fix the upper cutting blade 19 and the lower cutting blade 17. The protective shell 15 moves synchronously due to its sliding connection with the clamping plate 13, thereby applying downward pressure to the upper cutting blade 19 and upward pressure to the lower cutting blade 17. The two clamp each other and work together to cut the material. After the material is cut, it continues to be transported forward by the conveyor belt 1 and finally flows to the material box 3 through the discharge rack 2.
