[0026] Reference Figure 1 - Figure 4 The utility model provides an embodiment: a material cutting device for medical dressing processing, comprising a workbench 1, a bracket 2 is fixedly connected to the upper surface of the workbench 1, a motor 3 is fixedly connected to the inside of the bracket 2, a half gear 7 is fixedly connected to the output end of the motor 3, a linkage component is arranged on the outer wall of the half gear 7, the linkage component is used to drive the half gears 7 on both sides to rotate synchronously, a double-sided toothed plate 6 is slidably connected to the inside of the bracket 2, the double-sided toothed plate 6 is meshed with the half gear 7, a cutting knife 8 is fixedly connected to the bottom of the double-sided toothed plate 6, and a slide rod 9 is slidably connected to the inside of the cutting knife 8 The outer wall of the slide bar 9 is sleeved with a spring 10, one end of the spring 10 is fixedly connected to the outer wall of the cutting knife 8, and the other end of the spring 10 is fixedly connected to a pressure plate 12, and the pressure plate 12 fits the cutting knife 8. The top of the slide bar 9 is fixedly connected to a limiting block 11, and the outer wall of the cutting knife 8 is fixedly connected to a guide block 13. The outer wall of the guide block 13 is slidably connected to the inside of the bracket 2. The linkage assembly includes a cam 4, the inside of the cam 4 is fixedly connected to the outer wall of the half gear 7, and the outer wall of the cam 4 is provided with a transmission belt 5, and the cam 4 and the transmission belt 5 are both arranged inside the bracket 2.

[0027] Specifically, the medical dressing will first be sent to the bottom of the cutting knife 8, and then the motor 3 will be started, and the half gear 7 will be driven to rotate through the output end of the motor 3, thereby driving the cam wheel 4 to rotate, and then the rotation of the cam wheel 4 will drive the transmission belt 5 to move, and then drive the cam wheel 4 on the other side to rotate synchronously with the half gear 7. Due to the meshing relationship between the double-sided toothed plate 6 and the half gear 7, the double-sided toothed plate 6 will reciprocate up and down under the rotation of the half gears 7 on both sides, thereby driving the cutting knife 8 below to reciprocate and cut the medical dressing. When the cutting knife 8 moves downward, it will first drive the pressing plate 12 to fit the medical dressing, and then the spring 10 will contract with the gradual downward movement of the cutting knife 8, and then the thrust generated by the contraction of the spring 10 will push the pressing plate 12 to fix the medical dressing, and then the cutting knife 8 guided by the guide block 13 will cut the medical dressing, thereby achieving a rapid and stable cutting effect.

[0028] Reference Figure 2 , Figure 5 and Figure 6The workbench 1 is fixedly connected with a water tank 14 inside, the water tank 14 is fixedly connected with a delivery pipe 15 inside, a hose 16 is arranged in the middle of the delivery pipe 15, the outer wall of the delivery pipe 15 is fixedly connected to the inside of the workbench 1, one end of the delivery pipe 15 is fixedly connected to the inside of the pressing plate 12, a flow-equalizing cavity 18 is opened inside the pressing plate 12, a disinfection plate 17 is slidably connected inside the pressing plate 12, the disinfection plate 17 is fitted with the cutting knife 8, a conveyor belt 19 is arranged inside the workbench 1, a conveyor belt 20 is arranged inside the workbench 1, a support plate 21 is fixedly connected to the inside of the workbench 1, the support plate 21 is arranged between the conveyor belt 19 and the conveyor belt 20, and the support plate 21 is arranged below the cutting knife 8;

[0029] Specifically, during cutting, the cutting knife 8 will slide between the two pressing plates 12. At this time, the sliding cutting knife 8 can be disinfected by the disinfection plate 17 inside the pressing plate 12. At the same time, the disinfectant water inside the water tank 14 is transported to the equal flow cavity 18 inside the pressing plate 12 through the conveying pipe 15, and then the disinfection plate 17 is replenished with disinfectant water to achieve the effect of disinfecting the cutting knife 8. Then, the medical dressing can be continuously transported by the conveyor belt 1 19 and the conveyor belt 2 20. By arranging a support plate 21 under the cutting knife 8, the preset gap in the middle of the support plate 21 facilitates the cutting and support of the medical dressing.

[0030] Working principle: When the material cutting device for medical dressing processing is needed, first send the medical dressing to the bottom of the cutting knife 8, start the motor 3, and its output end drives the half gear 7 to rotate, thereby driving the concave wheel 4 and the transmission belt 5. The rotation of the concave wheel 4 causes the double-sided toothed plate 6 to move up and down under the drive of the half gears 7 on both sides, pushing the cutting knife 8 to perform reciprocating cutting. When the cutting knife 8 descends, the pressing plate 12 fits the dressing, the spring 10 contracts to fix the dressing, and the guide block 13 guides the cutting knife 8 to perform precise cutting, ensuring a fast and stable cutting effect.
