Description

Technical Field

[0001] This utility model relates to the field of medical gauze production technology, and in particular to a feeding mechanism for the production of medical gauze blocks. Background Technology

[0002] Medical gauze is a loose, porous mesh fabric made of woven degreased cotton fibers. It is one of the most commonly used basic dressings in clinical practice. Its core characteristics are excellent breathability and good moisture absorption. This open structure allows air to circulate freely, helping to keep the wound dry and reducing the risk of bacterial growth. At the same time, it can effectively absorb blood, tissue fluid, or pus from the wound, keeping the wound relatively clean. The main uses of medical gauze include covering and protecting the wound, assisting in pressure hemostasis, absorbing secretions, serving as a carrier for other drug dressings, and cleaning or wiping. Medical gauze undergoes strict sterilization to ensure safe and sterile use. It is an indispensable multifunctional material in wound care and is usually provided in sheet or roll form. The existing feeding mechanism cannot feed continuously, and the operation is complicated for workers when changing rolls. The feeding mechanism needs to be interrupted and stopped during the roll change process, which greatly affects the production efficiency and has an adverse impact on the production speed of products. In addition, the tension is difficult to control during the feeding process. If the tension is too low, the material will loosen, stack, and deviate. If the tension is too high, the gauze will be stretched and deformed, or even break, which will greatly reduce the yield of products. Breakage will also affect the continuous production of medical gauze. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A feeding mechanism for producing medical gauze pads includes a cylinder and a first rotating shaft fixedly passing through the middle of the cylinder. Support frames are rotatably connected to both sides of the first rotating shaft, and multiple connecting frames are rotatably connected to both sides of the first rotating shaft. A fixing component is fixedly connected to one side of each of the multiple connecting frames. A roller assembly is fixedly installed between two adjacent fixing components. The roller assembly includes a round rod fixedly installed between the fixing components. A round roller is fixedly connected to the outer side of the round rod. Multiple protrusions are fixedly connected to the outer side of the round roller. A disc is fixedly connected to the middle of the round roller. A ring rail is rotatably connected to the outer side of the disc. A roller shell is fixedly connected to the outer side of the ring rail. Multiple tension control components are fixedly connected to the inner wall of the roller shell.

[0005] Preferably, the tension control assembly includes a concave block fixedly connected to the inner wall of the roller housing, a convex block slidably connected to one side of the concave block, a first spring fixedly connected between the concave block and the convex block, a second spring fixedly connected to both sides of the convex block, and a concave plate fixedly connected to one side of the second spring.

[0006] Preferably, the fixing component includes a fixing block fixedly connected to one end of the connecting frame, a connecting block slidably connected to one side of the fixing block, and a third spring fixedly connected between the connecting block and the fixing block.

[0007] Preferably, a motor is fixedly connected to one side of the support frame, a first rotating roller is fixedly connected to the output end of the motor, a first gear is fixedly connected to one side of the first rotating roller, the first rotating roller and the support frame are rotatably connected, a second rotating roller is rotatably connected to one side of the support frame, a second gear is fixedly connected to one side of the second rotating roller, and the first gear and the second gear mesh with each other.

[0008] Preferably, a correction component is fixedly connected to one side of the support frame. The correction component includes a fourth spring fixedly connected to one side of the support frame, a connecting plate fixedly connected to one side of the fourth spring, and a correction track fixedly connected to one side of the connecting plate.

[0009] Preferably, a shock-absorbing pad is fixedly connected to the lower side of the support frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of multiple sets of roller assemblies and the cooperation of multiple connecting frames with fixing components, makes it very simple and convenient to fix and install, disassemble and install with the roller assemblies, which facilitates the change of rolls in continuous production process, greatly improves production efficiency, reduces the workload of workers, and speeds up production. 2. Furthermore, the roller assembly, through the cooperation of the convex strip and the correction component, when a certain tension is reached, the tension pulls the yarn, so that the tension of the yarn is just right, neither too high nor too low. When the tension is too high, the first spring and the second spring are squeezed, the tension control component compresses past the convex strip, the roller rotates, and at the same time the yarn tension is reduced and the material is released.

Detailed Implementation

[0013] Reference Figures 1-9A feeding mechanism for producing medical gauze pads includes a cylinder 2 and a first rotating shaft 10 fixedly passing through the middle of the cylinder 2. Support frames 9 are rotatably connected to both sides of the first rotating shaft 10. Shock-absorbing pads are fixedly connected to the lower side of the support frames 9 to prevent vibrations during operation from affecting the gauze feeding deviation. Multiple connecting frames 11 are rotatably connected to both sides of the first rotating shaft 10. A fixing component 12 is fixedly connected to one side of each of the multiple connecting frames 11. A roller assembly 3 is fixedly installed between two adjacent fixing components 12. The multiple roller assemblies 3 cooperate with each other. When one roller assembly 3 is feeding, the other roller assemblies 3 are replaced in time, greatly improving work efficiency and eliminating the need for machine downtime for replacement, ensuring continuous production. The roller assembly 3 includes a round rod 13 fixedly installed between the fixing components 12. A round roller 14 is fixedly connected to the outside of the round rod 13. Multiple protrusions 16 are fixedly connected to the outside of the round roller 14. A disc 18 is fixedly connected to the middle of the round roller 14. A ring rail is rotatably connected to the outside of the disc 18. 17. A roller housing 15 is fixedly connected to the outer side of the ring rail 17. Multiple tension control components 19 are fixedly connected to the inner wall of the roller housing 15. The tension control components 19 and the gaps between adjacent protrusions 16 are opposite. The tension control components 19 include a concave block 20 fixedly connected to the inner wall of the roller housing 15. A protrusion 22 is slidably connected to one side of the concave block 20. A first spring 21 is fixedly connected between the concave block 20 and the protrusion 22. A second spring 24 is fixedly connected to both sides of the protrusion 22. A concave plate 23 is fixedly connected to one side of the second spring 24. The tension control components 19 are limited by the elasticity of the first spring 21 and the second spring 24. When the tension of the unloaded yarn is about to become too large, the first spring 21 and the second spring 24 are compressed. At the same time, the concave plate 23 slides between the protrusions 16 and the tension control components 19, so that the tension control components 19 cross the protrusions 16 and reach the gap between the other protrusions 16. At the same time, the roller housing 15 rotates along the ring rail 17 to achieve the effect of unloading the yarn and control the tension of the yarn. The fixing component 12 includes a fixing block 25 fixedly connected to one end of the connecting frame 11. A connecting block 27 is slidably connected to one side of the fixing block 25. A third spring 26 is fixedly connected between the connecting block 27 and the fixing block 25 to facilitate the disassembly and installation of the roller assembly 3. A motor 1 is fixedly connected to one side of the support frame 9. A first rotating roller 5 is fixedly connected to the output end of the motor 1. A first gear 7 is fixedly connected to one side of the first rotating roller 5. The first rotating roller 5 and the support frame 9 are rotatably connected. A second rotating roller 6 is rotatably connected to one side of the support frame 9. A second gear 8 is fixedly connected to one side of the second rotating roller 6. The first gear 7 and the second gear 8 mesh with each other. A correction component 4 is fixedly connected to one side of the support frame 9. The correction component 4 includes a fourth spring 28 fixedly connected to one side of the support frame 9. A connecting plate 29 is fixedly connected to one side of the fourth spring 28. A correction track 30 is fixedly connected to one side of the connecting plate 29. The yarn enters between the first rotating roller 5 and the second rotating roller 6 through the correction track 30 to prevent the yarn from shifting during the feeding process.

[0014] In this invention, when medical gauze needs to be fed, motor 1 is first started. Motor 1 drives the first roller 5 to rotate, the first roller 5 drives the first gear 7 to rotate, the first gear 7 drives the second gear 8 to rotate, and the second gear 8 drives the second roller 6 to rotate. The rotation direction of the first roller 5 and the second roller 6 is from between the two rollers to the outside of the two rollers. Then, the unfed roller assembly 3 is installed between the fixing components 12 of the multiple connecting frames 11. When the gauze on one roller assembly 3 is fed, the connecting frame 11 is rotated to replace it with another roller assembly 3 between the other pair of connecting frames 11. At the same time, the roller assembly 3 that has finished feeding is replaced, which greatly improves efficiency. During feeding, the tension control component 19 controls the feeding through the first spring 21 and the second spring 2. With the elastic limit of 4, when the tension of the unloaded gauze is about to become too large, the first spring 21 and the second spring 24 are compressed, and the concave plate 23 slides between the convex strip 16, causing the tension control component 19 to pass over the convex strip 16 and reach the gap of another convex strip 16. At the same time, the roller housing 15 rotates along the ring rail 17 to achieve the effect of unloading the gauze and control the tension of the gauze. The gauze unloaded from the roller assembly 3 passes through the correction track 30 to prevent the gauze from deviating during the unloading process, which would cause unnecessary accumulation or even tearing, thus ensuring the continuity of production. The gauze that has passed through the correction track 30 then passes through the bottom between the first roller 5 and the second roller 6, and then passes out from the upper side between the first roller 5 and the second roller 6, completing the unloading process of the medical gauze.
