DETAILED DESCRIPTION

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0044] like Figures 1 to 4 As shown, a medical absorbent cotton preparation device described in an embodiment of the present invention comprises a support frame 1, a conveying assembly 4 is arranged on one side of the support frame 1, a degreasing machine 5, a cutting machine 6 and a packaging machine 7 are arranged outside the conveying assembly 4, a transmission belt 11 is arranged above the support frame 1, a servo motor for driving the transmission belt 11 is installed at one end of the support frame 1, a cleaning tank 12 is arranged inside the support frame 1, and the middle part of the transmission belt 11 extends into the inside of the cleaning tank 12, a water spray frame 2 is arranged above the support frame 1, a mounting frame 21 is fixed above the water spray frame 2, the mounting frame 21 is fixed to the top of the support frame 1, a water pump 23 is installed at one end of the support frame 1, a cleaning assembly for cleaning scum is arranged below the water spray frame 2, a support shell 3 is fixed on one side of the top of the support frame 1, a feed pipe 31 is fixed inside the support shell 3, and a material dividing assembly is arranged inside the support shell 3;

[0045] When preparing medical absorbent cotton, pure cotton fiber is put into the inside of the feed pipe 31. At this time, the feed pipe 31 guides the pure cotton fiber to the top of the transmission belt 11. The servo motor drives the transmission belt 11 to transport the pure cotton fiber. During the transportation process, the material separation component pulls the inside of the pure cotton fiber to separate the pure cotton fiber from the leaves. Then the pure cotton fiber is transported to the inside of the cleaning tank 12, and the water pump 23 transports the cleaning liquid to the water spray rack 2. The cleaning liquid is sprayed through the water spray rack 2 to rinse the pure cotton fiber. During the rinsing, the cleaning component cleans the floating leaves, and then the transmission belt 11 transports the cleaned pure cotton fiber to the outside. Then the pure cotton The fibers fall on the top of the conveying component 4, and the conveying component 4 conveys the cleaned pure cotton fibers. The pure cotton fibers at the top of the conveying component 4 are degreased by the degreasing machine 5, and then continue to be conveyed by the conveying component 4. Then the pure cotton fibers pass through the inside of the cutting machine 6 and are cut into the required shape and size. Finally, the conveying component 4 conveys the cut pure cotton fibers to the packaging machine 7. The pure cotton fibers are first dried by the built-in drying box of the packaging machine 7. After drying, the packaging machine 7 packages the pure cotton fibers. The packaged pure cotton fibers are transported to the outside through the conveying component 4, and the preparation of the absorbent cotton can be completed.

[0046] like Figures 1 to 5 As shown, the cleaning assembly includes an overflow port 121 opened at the top of the support frame 1, and a collecting shell 22 is fixed to one end of the support frame 1 close to the overflow port 121. The collecting shell 22 is located below the overflow port 121. A filter plate is arranged inside the collecting shell 22. The bottom end of the collecting shell 22 is connected to the water inlet pipe of the water pump 23.

[0047] When flushing pure cotton fibers, the water level inside the cleaning tank 12 is flush with the bottom of the overflow port 121, and the water spray rack 2 sprays cleaning liquid to flush the pure cotton fibers. During the flushing process, the water level inside the cleaning tank 12 will continue to rise. At this time, the blade fragments flushed out will rise with the water level. When the water level rises, the cleaning liquid will flow into the interior of the collecting shell 22 through the overflow port 121. At this time, the blade fragments will flow into the interior of the collecting shell 22 at the same time as the cleaning liquid. The filter plate inside the collecting shell 22 can filter out impurities in the cleaning liquid, and then the cleaning liquid can be recycled by extraction by the water pump 23.

[0048] like Figures 1 to 7As shown, a connecting shell 24 is provided above the water pump 23, a water inlet 241 is fixed on one side of the connecting shell 24, a water outlet 242 is fixed on the other side of the connecting shell 24, the top of the connecting shell 24 is fixedly connected to the supporting shell 3 through a connecting rod, the water outlet pipe of the water pump 23 is connected to the water inlet 241, the water outlet 242 is connected to one end of the water spraying frame 2 through a water pipe, the bottom end of the connecting shell 24 is rotatably connected to a turning frame 25, the top end of the turning frame 25 is fixed with a water wheel 251, the water wheel 251 is rotatably connected to the inside of the connecting shell 24, the outer diameter of the water wheel 251 matches the inner diameter of the connecting shell 24, a mesh plate 26 is provided below the turning frame 25, the bottom of the mesh plate 26 extends to the inside of the cleaning tank 12, and a plurality of water spray nozzles are installed at equal intervals at the bottom end of the water spraying frame 2;

[0049] When the water pump 23 transports the cleaning liquid to the inside of the water spray rack 2, it will pass through the inside of the connecting shell 24. When the cleaning liquid enters the inside of the connecting shell 24, it will drive the water wheel 251 to rotate. At this time, the water wheel 251 drives the flip rack 25 to flip. When the flip rack 25 flips, it drives the mesh plate 26 to move. During the movement of the mesh plate 26, it will push the blade fragments floating in the cleaning tank 12, which can assist the blades to be discharged from the overflow port 121, and can prevent the blades from getting stuck and unable to be cleaned when floating in the overflow port 121. The water spray rack 2 can spray the cleaning liquid onto the surface of the pure cotton fiber through multiple water nozzles, so as to achieve the cleaning of the pure cotton fiber.

[0050] like Figures 1 to 7 As shown, the flip frame 25 is composed of six flip rods, each of which is fixed with a support block 252 at both ends, and a rotating shaft is fixed at both ends of the mesh plate 26, the rotating shaft is rotatably connected to the inside of the support block 252, and a coil spring 253 is fixed to the outside of the rotating shaft, and the outermost side of the coil spring 253 is fixedly connected to the support block 252;

[0051] When the mesh plate 26 flips over and passes through the outer wall of the support frame 1 on the side of the overflow port 121, the mesh plate 26 will be blocked by the support frame 1. At this time, the flip frame 25 continues to rotate and the mesh plate 26 will be pushed and flipped by the support frame 1. At this time, the mesh plate 26 will flip inside the support block 252 through the rotating shafts at both ends. At this time, the coil spring 253 will be tightened by the rotating shaft. When the mesh plate 26 passes the outer wall, the coil spring 253 will drive the mesh plate 26 to flip in the opposite direction through the rotating shaft, and can drive the mesh plate 26 to return to its original position.

[0052] like Figures 1 to 7 As shown, a scraper 221 is fixed to one end of the top of the collecting shell 22 away from the overflow port 121;

[0053] When the mesh plate 26 passes through the scraper 221 , the mesh plate 26 will be lifted up by the scraper 221 . During the lifting process, the scraper 221 will scrape the surface of the mesh plate 26 to clean the surface of the mesh plate 26 and prevent blade fragments from adhering to the surface of the mesh plate 26 .

[0054] like Figures 1 to 8 As shown, the material dispensing assembly includes a camera 33 installed at the top of the inner side of the support shell 3 near the feeding pipe 31, a displacement motor 32 is installed at one end of the support shell 3, two threaded rods 322 are rotatably connected inside the support shell 3, and a moving block 321 is threadedly connected to the outer side of the threaded rod 322, one end of one of the threaded rods 322 is fixedly connected to the end of the rotating shaft of the displacement motor 32, and a gear 323 is fixed at one end of the threaded rod 322 away from the displacement motor 32, and the gears 323 at one end of the two threaded rods 322 are meshed and connected;

[0055] During the process of flushing the pure cotton fiber by the water spray rack 2, the blade fragments may be stuck inside the pure cotton fiber. At this time, the pure cotton fiber at the top of the transmission belt 11 is detected by the camera 33. When the blade fragments are detected inside the pure cotton fiber, the displacement motor 32 is started to drive the threaded rod 322 to rotate, and the threaded rod 322 drives the moving block 321 to move, so that the moving block 321 moves to the position of the pure cotton fiber that needs to be processed. After the moving block 321 moves to the position of the pure cotton fiber, the blade fragments inside the pure cotton fiber can be processed conveniently.

[0056] like Figures 1 to 9 As shown, guide plates 34 are fixed on both sides of the bottom of the moving block 321, an electric telescopic rod 342 is arranged between the two guide plates 34, the top of the electric telescopic rod 342 is fixedly connected to the moving block 321, a lifting block 343 is fixed to the bottom of the electric telescopic rod 342, both sides of the lifting block 343 are rotatably connected to the insertion rack 344, guide sliding holes 341 are opened on both sides of the inside of the guide plate 34, guide rods are fixed on both sides of the bending part of the insertion rack 344, and the guide rods are slidably connected to the inside of the guide sliding holes 341;

[0057] When the moving block 321 moves and drives the insertion rack 344 to be located on both sides of the blade fragments, the electric telescopic rod 342 is started to push the lifting block 343 downward. At this time, the lifting block 343 pushes the insertion rack 344 to move downward. When the insertion rack 344 moves downward, the guide rods at both ends slide inside the guide sliding hole 341. Under the guidance of the guide sliding hole 341, the insertion rack 344 will move straight downward first. During the straight downward movement of the insertion rack 344, the oblique rod at the bottom end will be inserted into the interior of the pure cotton fiber. When the insertion rack 344 moves to the bending area of ​​the guide sliding hole 341, the guidance of the bending area of ​​the guide sliding hole 341 can make the insertion rack 344 expand to both sides. In this process, the insertion rack 344 pulls the pure cotton fiber to move to both sides. At this time, the insertion rack 344 can tear the pure cotton fiber apart, Fig. 9It can be seen that the two material insertion racks 344 are symmetrically arranged, and the bottom ends of the material insertion racks 344 are inclined rods. The inclined rods at the bottom ends of the two material insertion racks 344 are close to the middle. At this time, the material insertion racks 344 can be inserted into the cotton fiber to be closer to the center of the pure cotton fiber. Tearing the pure cotton fiber from the more central part will make it easier to expose the leaf fragments in the pure cotton fiber. After the leaf fragments are exposed, they are fixed and easier to separate from the pure cotton fiber. Through subsequent flushing, the leaf fragments can be more easily flushed out of the pure cotton fiber, and a better flushing effect can be achieved when the water spray rack 2 flushes the pure cotton fiber.

[0058] like Figures 1 to 10 As shown, a material pushing frame 35 is arranged between the material insertion racks 344, telescopic columns 351 are fixed on both sides of the top of the material pushing frame 35, a guide cylinder 352 is arranged above the telescopic column 351, the top of the telescopic column 351 extends to the inside of the guide cylinder 352, a spring 353 is fixed to the top of the telescopic column 351, and the top of the spring 353 is fixedly connected to the inner wall of the guide cylinder 352;

[0059] After the material insertion rack 344 tears the pure cotton fiber, the electric telescopic rod 342 drives the lifting block 343 to rise. At this time, the material insertion rack 344 is easy to clamp the pure cotton fiber. To prevent this problem, a pushing frame 35 is set between the material insertion racks 344. When the pushing frame 35 is stuck between the two material insertion racks 344, the spring 353 is in a compressed state. When the material insertion rack 344 is opened, the pushing frame 35 is released, and then the spring 353 releases the elastic force to push the telescopic column 351, and the telescopic column 351 pushes the pushing frame 35 to move downward When the pushing frame 35 moves downward, it will push the pure cotton fibers downward, so that the pure cotton fibers can be separated from the insertion rack 344, and the pure cotton fibers can be prevented from being clamped when the insertion rack 344 is raised. At the same time, when the insertion rack 344 is raised, the guide of the guide slide hole 341 will gather the pure cotton fibers. At this time, the insertion rack 344 can clamp the pushing frame 35 and move the pushing frame 35 upward through the guidance of the insertion rack 344. During the movement of the pushing frame 35, the telescopic column 351 is driven to squeeze the spring 353 into the guide cylinder 352.
