[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This specific embodiment is a cutting device for producing medical repair patches, such as... Figure 1 and Figure 2 As shown, the cutting device for producing medical repair patches includes a mounting base 1. An auxiliary conveying assembly is mounted on the top of the mounting base 1. The conveying assembly includes a conveyor shaft 2 rotatably mounted on the mounting base 1, with a conveyor belt 3 wound around the conveyor shaft 2. A conveyor motor 4, which drives the conveyor shaft 2, is mounted on one side of the mounting base 1. A mounting frame 13 is mounted at the center of the top of the mounting base 1. Protruding plates 5 are mounted on both sides of the top of the mounting base 1 corresponding to the mounting frame 13. Insertion pins 7 are rotatably mounted on the protruding plates 5, and winding shafts 6 are mounted on the insertion pins 7. The protruding plates 5 are located away from the insertion pins 6. A servo motor that drives the insertion post 7 to rotate is installed on one side of the post 7. The insertion post 7 is U-shaped and has a positioning cavity. A positioning component 8 is installed in the positioning cavity. A positioning hole 9 is opened on the side of the winding shaft 6. The positioning component 8 is fixed to the positioning hole 9. The positioning component 8 includes a first slide rod 11 that is vertically fixed in the positioning cavity. A positioning pin 10 is sleeved on the first slide rod 11. The top of the positioning pin 10 passes through the positioning cavity and extends into the positioning hole 9. A first pressure spring 12 that helps the positioning pin 10 to be lifted is sleeved on the first slide rod 11.
[0028] By cooperating with the positioning component 8 on the insertion post 7 and the positioning hole 9 on the winding shaft 6, the winding shaft 6 with the repair fit is inserted and installed on the insertion post 7. Pulling the positioning pin 10 compresses the first top pressure spring 12, which pushes the winding shaft 6 to be snapped onto the insertion post 7. Releasing the positioning pin 10 allows the positioning pin 10 to be inserted into the positioning hole 9 under the action of the compressed first top pressure spring 12. This allows for quick replacement of the winding shaft 6 before and after operation, minimizing the inconvenience of disassembling and assembling the winding shaft 6 as a whole.
[0029] like Figure 1 , Figure 3 and Figure 4As shown, a protruding plate 21 is provided near the bottom of the mounting frame 13, and a cutting template 22 is installed at the top of the protruding plate 21. A cutting plate 15 is slidably mounted on the mounting frame 13. An electric push rod 14 for adjusting the position of the cutting plate 15 is installed at the top of the mounting frame 13. A clamping assembly 16 for auxiliary clamping is installed on both sides of the cutting plate 15. The clamping assembly 16 includes a protruding block 17 that is fixed on the cutting plate 15. A second slide rod 18 is installed through the protruding block 17. A clamping plate 20 is fixed at the bottom of the second slide rod 18. A second top pressure spring 19 is sleeved on the clamping plate 20 corresponding to the second slide rod 18.
[0030] By cooperating with the clamping components 16 on both sides of the cutting plate 15, the electric push rod 14 is activated. The electric push rod 14 extends and drives the cutting plate 15 to descend as a whole. When the cutting plate 15 descends, the clamping plate 20 presses against the top of the repair patch. As the cutting plate 15 continues to descend, it drives the clamping plate 20 to rise, thereby compressing the second top pressure spring 19 as a whole. This effectively presses against the edge of the repair patch during the downward cutting process, minimizing the possibility of the repair patch shifting during pressing and minimizing the possibility of the fabric shifting as a whole during the cutting process, thus ensuring the smooth progress of subsequent work.
[0031] The cutting template 22 is provided with a punching cavity. Each of the four corners of the cutting template 22 is provided with a through post 221. The protruding plate 21 is provided with a through hole 211. The through post 221 and the through hole 211 are fitted together. The protruding plate 21 is provided with symmetrical insertion cavities. The insertion cavity is provided with a fixing hole 212. The bottom of the cutting template 22 is provided with symmetrical protruding insertion plates 222. The insertion plates 222 are threaded with positioning bolts 223. The positioning bolts 223 are fitted together with the fixing holes 212.
[0032] By cooperating with the cutting template 22, the through post 221, and the through hole 211 set on the protruding plate 21, different shapes of cutting template 22 can be easily replaced according to different work requirements during operation, thereby improving the overall practicality of the device.
[0033] Working principle:
[0034] Before starting work, the winding shaft 6 with the repair fit is threaded through and installed on the plug post 7, and the positioning pin 10 is pulled. When the positioning pin 10 is pulled, the first top pressure spring 12 is compressed. At this time, the winding shaft 6 is pushed and snapped onto the plug post 7. The positioning pin 10 is released, and under the action of the compressed first top pressure spring 12, the positioning pin 10 is inserted into the positioning hole 9.
[0035] Place the cutting template 22 on top of the protruding plate 21, and make the through post 221 and through hole 211 fit together and insert the insertion plate 222 into the insertion cavity. Rotate the positioning bolt 223, and the positioning bolt 223 and the insertion plate 222 are threaded together, so that the positioning bolt 223 is snapped into the insertion plate 222.
[0036] The repair patch is passed through the cutting plate 15 and the clamping assembly 16 and wound into the winding shaft 6 at the other end. The servo motor is started, which moves the repair patch. The electric push rod 14 is started, which extends and causes the cutting plate 15 to descend as a whole. As the cutting plate 15 descends, the clamping plate 20 presses against the top of the repair patch. As the cutting plate 15 continues to descend, it causes the clamping plate 20 to rise, thereby compressing the second top pressure spring 19 as a whole. This effectively presses against the edge of the repair patch during the downward cutting process, minimizing the possibility of the repair patch shifting during pressing.
[0037] Start the conveyor motor 4, which drives the conveyor shaft 2 to rotate as a whole. The conveyor shaft 2 then drives the conveyor belt 3 to move as a whole, thereby effectively conveying the cut repair patch.
[0038] All technical features in this embodiment can be freely combined according to actual needs.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
