[0016] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the examples listed.

[0017] like Figures 1 to 3As shown, a pearl cotton cutting device of this embodiment includes a positioning component 1 and a cutting component 2 arranged on the side of the positioning component 1. The positioning component 1 and the cutting component 2 are arranged on the bottom plate 3. After the material is positioned by the positioning component 1, it is cut by the cutting component 2. The cutting component 2 includes a bracket 21, a drive cylinder 22, a connecting plate 23, a limit frame 24 and a support seat 25. The drive cylinder 22 is arranged on the bracket 21 and connected to the connecting plate 23. A plurality of drive cylinders 22 are arranged at intervals, and the connecting plate 23 can be driven to move by a plurality of drive cylinders 22. The bracket 21 is provided with a synchronous rod 26 and a synchronous wheel 27. A plurality of synchronous wheels 27 are sleeved on the synchronous rod 26 and rotate synchronously with the synchronous rod 26. The connecting plate 23 is provided with a rack 28, the rack 28 is vertically arranged, and the synchronous wheel 27 is meshed with the rack 28, so that the rack 28 can be driven to move by the rotation of the synchronous wheel 27. The rack 28 and the synchronous wheel 27 are both provided with meshing teeth, so that they mesh. The connecting plate 23 is provided with a cutting knife 29, and the limiting frame 24 is arranged on the supporting seat 25. The limiting frame 24 has a limiting perforation 241 and a guide hole 242. The limiting perforation 241 is arranged along the movement direction of the pearl cotton, and the guide hole 242 is arranged in the vertical direction and is arranged corresponding to the cutting knife 29. In the above technical scheme, when the material 10 is cut, the material passes through the limiting perforation 241 and is transported to the position of the positioning component 1. It can be transported manually or by an existing conveyor, and the positioning component 1 presses the material. The connecting plate 23 is driven downward by the driving cylinder 22, so that the cutting knife 29 descends and enters the guide hole 242 to cut the material. When the connecting plate 23 descends, the rack 28 descends synchronously. The two racks can make the connecting plates 23 on both sides descend synchronously, so that the cutting knife 29 remains horizontal during the descending process, thereby ensuring the cutting effect. Through the above technical scheme, the cutting knife can be made to descend smoothly and the cutting effect can be ensured.

[0018] In this embodiment, the positioning assembly 1 includes a guide rod 11, a cross bar 12, a power device 13 and a positioning plate 14.

A support 15 is provided on the base plate 3, and a plurality of supports 15 are arranged at intervals and are located below the positioning plate 14. In the above technical scheme, the positioning plate 14 is driven downward by the power device 13 to press the material 10 on the support 15 for positioning. By setting the guide rod 11, the positioning plate 14 can be made to descend more smoothly. In this embodiment, the driving cylinder 22 and the power device 13 are both hydraulic cylinders. The bracket 21 is provided with a shaft seat 211, and the synchronization rod 26 is inserted into the shaft seat 211. A bearing is arranged in the shaft seat 211, so that the synchronization rod 26 can rotate flexibly. There are two synchronization rods 26, which are arranged in parallel on both sides of the rack 28. The front and back sides of each rack 28 are meshed with the synchronization wheel 27, so that the movement of the rack can be smoother. There are two driving cylinders 22, which are arranged at both ends of the connecting plate 23. The rack 28 is located between the driving cylinders 22. Through the synchronous movement of the two driving cylinders 22, the connecting plate 23 can be stably lifted and lowered even when the size is large. A guide rail 4 is provided under the bottom plate 3. The guide rail 4 is arranged in the horizontal direction, so that the bottom plate 3 can slide along the guide rail 4, so that the cutting device can adjust its position according to the cutting requirements. The guide rail 4 is provided with a plurality of sliding blocks 5, and the bottom plate 3 is arranged on the sliding blocks 5. The bottom plate 3 is connected to the driving cylinder 6, and the bottom plate 3 can be driven to move by the driving cylinder 6.
