Description

Technical Field

[0001] The present invention relates to the technical field of medical dressing production, and specifically relates to a waste edge recycling treatment device on a medical dressing production line. Background Art

[0002] Various die-cutting machines are mostly used in medical dressing production lines to obtain medical dressings with specific shapes by performing specific cutting on a roll material, such as plaster patches, wound dressings, and medical tapes.

[0003] The waste edges remaining after cutting of the existing medical dressings are generally collected by a rotating drum. As a result, the rotating drum needs to be replaced after winding enough waste edges. When replacing, the operation of the medical dressing forming machine needs to stop for a long time, resulting in waste of time and reduced production efficiency. If not replaced for a long time, the waste edges may side-slip on the drum, pulling the raw material on the forming machine out of position and causing waste of the raw material. Summary of the Invention

[0035] The usage process of the present invention is as follows: When using the present invention, start the second motor 11. The second motor 11 controls the rotation of the winding shaft 12, and the winding shaft 12 drives the winding disc 4 to rotate. The winding disc 4 at the bottom of the top frame 5 winds the waste edge. When the waste edge is wound enough, start the first motor 9. The first motor 9 controls the rotation of the transmission shaft 10, and the transmission shaft 10 drives the rotating disc 3 to rotate. The rotating disc 3 drives the winding disc 4 that has wound the waste edge to rotate and move out of the bottom of the top frame 5, and another winding disc 4 that has not wound the waste edge moves to the bottom of the top frame 5. At this time, the waste edge is stretched and approaches the winding disc 4 that has not wound the waste edge. Then start the hydraulic push rod 8. The hydraulic push rod 8 controls the downward movement of the square shell 7 and the disc 6. The disc 6 drives the connecting block 17 to move downward, and the connecting block 17 drives the connecting plate 19 to move downward. The connecting plate 19 passes through the card slot 18 on one side of the winding disc 4 that has not wound the waste edge. Then start the fourth motor 20. The fourth motor 20 drives the rotating rod 21 to rotate, and the rotating rod 21 drives the connecting shell 22 to rotate, so that the connecting shell 22 presses the stretched waste edge into the outside of the winding disc 4. The waste edge is limited by the fourth motor 20 and the connecting plate 19. Then start the fifth motor 25. The fifth motor 25 drives the first lead screw 29 to rotate, and the first lead screw 29 drives the threaded base 41 to move. The threaded base 41 drives the rotating plate 33 to move, and the rotating plate 33 drives the connecting seat 32 to move. The connecting seat 32 pushes the fixing plate 34 to move. The fixing plate 34 drives the toothed plate 35 to move out of the toothed plate groove 36, so that the toothed plate 35 presses the waste edge against the side of the connecting plate 19. At the same time, the fixing plate 34 drives the slider 40 to move, and the slider 40 drives the cutting knife 39 to move out of the knife slot 37 and into a part of the knife slot 27. The telescopic rod 38 extends. Then start the sixth motor 26. The sixth motor 26 controls the rotation of the second lead screw 30, and the second lead screw 30 drives the sliding block 31 to move. The sliding block 31 drives the telescopic rod 38 to move, and the telescopic rod 38 drives the slider 40 to move. One side of the slider 40 slides inside the slider groove 42. At the same time, the moving cutting knife 39 divides the waste edge. After the waste edge is divided, since the waste edge is pressed tightly by the toothed plate 35, at this time start the second motor 11. The second motor 11 controls the rotation of the winding shaft 12, and the winding shaft 12 drives the winding disc 4 to rotate. The winding disc 4 starts to continue winding the waste edge. The winding disc 4 drives the connecting plate 19 and the connecting shell 22 to rotate. The connecting plate 19 drives the connecting block 17 to rotate. The third motor 13 drives the disc 6 to rotate, so that the connecting plate 19 and the connecting shell 22 rotate synchronously with the winding disc 4. After winding multiple circles, control the toothed plate 35 to retract back into the connecting shell 22. At this time, the waste edge is no longer pressed tightly. Start the hydraulic push rod 8. The hydraulic push rod 8 drives the connecting plate 19 and the connecting shell 22 to move out of the winding disc 4. Then continue the waste edge winding work. While winding the waste edge, rotate the rotating handle 14. The rotating handle 14 drives the pressing plate 15 to rotate, and the pressing plate 15 drives the screw rod 16 to move out of the winding shaft 12, which is convenient for disassembling the winding disc 4 full of waste edge and replacing it with a new winding disc 4.
