Description

Technical Field

[0001] This application relates to the field of preparation equipment technology, and in particular to a preparation equipment for an antibacterial coating material for bone plates. Background Technology

[0002] Polymers are an important component of biomedical materials. Their superior properties, diverse structures, and wide adaptability have led to a growing trend of them gradually replacing traditional materials in various medical device industries. Currently, there are 12 types of polymer materials widely used in medical devices globally, and nearly 300 types of medical implants, such as joint prostheses and artificial organs, have been developed and applied using existing biomedical materials.

[0003] Graphene is a type of poly(phosphorus) material. 2 Graphene is a novel material composed of hybridized carbon atoms tightly packed into a single-layer two-dimensional honeycomb lattice structure. It possesses excellent optical, electrical, and mechanical properties and holds significant promise for applications in materials science, micro / nano fabrication, energy, biomedicine, and drug delivery, and is considered a revolutionary material for the future.

[0004] Graphene coatings can be used as antibacterial materials to prepare antibacterial coatings. The preparation process requires ultrasonic cleaning of the polymer, followed by immersion in a coupling agent. During immersion, the coupling agent needs to gradually penetrate to achieve complete immersion of the polymer. However, during this immersion process, the polymer accumulates together, which prevents it from quickly penetrating the inner polymer layer, thus affecting the efficiency of polymer immersion.

The second gear is located at the input end of the rotating rod, which is rotatably connected to the bottom of the base box. One end of the rotating rod is located inside the chassis, and a vertical groove is provided on the rotating rod inside the chassis.

[0008] Preferably, a rotating cylinder is inserted into the vertical groove of the rotating rod, and side frames are connected to the two ends of the rotating cylinder. The rotating cylinder is rotatably connected to the corresponding side frames. The side frames on both sides of the rotating rod are respectively set at the bottom of the outer cylinder, and the diameter of the rotating cylinder between the side frames is the same as the width of the vertical groove.

[0009] Preferably, the third gear inside the chassis is hollow in the middle, a rotating rod is inserted into the middle of the third gear, a rotating plate is connected to the rotating rod above the third gear, the rotating plate is parallel to the third gear inside the chassis, and the end of the rotating plate is connected to the connection point of the worm gear and the fourth gear.

[0014] Preferably, a horizontal frame is slidably connected to the second vertical rod, the horizontal frame is perpendicularly connected to the second vertical rod, and a first vertical rod is provided on the other end of the horizontal frame, the first vertical rod being connected to the corresponding box.

The first spring is located on the second vertical rod below the crossbeam, and the two ends of the first spring are respectively connected to the crossbeam and the side plate.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] This solution involves installing a rotating rod at the bottom of the chassis. A second gear is connected to the outer end of the rotating rod, meshing with the first gear at the output of a servo motor. The servo motor then drives the rotating rod to rotate. An outer cylinder is connected to the rotating rod, inside which is placed an inner cylinder. The rotating rod drives both the outer and inner cylinders to rotate, allowing the polymer to be soaked to be placed inside. The servo motor then drives both the inner and outer cylinders to rotate. The outer cylinder is slidably connected to the corresponding vertical groove on the rotating rod via the rotating rod. A rotating plate is located on the rotating rod below the outer cylinder, with a vertical plate on the plate. A worm gear and a fourth gear can be mounted on the rotating plate, and the fourth gear can engage with... The third gear engages, and when the rotating rod rotates, the rotating plate also rotates. The fourth gear on the rotating plate rotates under the engagement of the third gear. The worm gear drives the worm wheel on one side to rotate, and the worm wheel drives the convex head to rotate through the linkage rod. The convex head drives the linkage frame to move up and down. When the linkage frame moves up and down, it pushes the outer cylinder, causing the outer cylinder to move up and down. The frequency of the outer cylinder's up and down movement is constant, and the outer cylinder drives the inner cylinder to move vertically. During the movement, the coupling agent can move the polymer in the inner cylinder, thereby preventing the polymer from accumulating stably, thus facilitating the soaking of the coupling agent and improving efficiency.

[0018] This solution utilizes a cylinder installed at the mounting port of the chassis to raise and lower the top plate, facilitating the loading and unloading of polymers. The top plate contains a storage tank for deionized water. After the polymer soaking is complete, the coupling agent is drained. Following this, the top plate is moved to a specific position by the cylinder, and then a servo motor is activated. This motor rotates the inner and outer cylinders, causing them to move up and down. The upward movement of the inner and outer cylinders pushes the discharge tank, which then moves upward along the second vertical rod via a crossbar. This upward movement allows the internal opening to be unobstructed, enabling the deionized water to flow onto the polymer in the inner cylinder for cleaning. The vertical movement of the inner cylinder prevents polymer accumulation, ensuring even cleaning with deionized water. This eliminates the need to move the polymer to other equipment for cleaning, thus accelerating the polymer preparation process. Attached Figure Description

[0031] Example 1:

[0032] like Figures 1 to 8 As shown, the preparation equipment for an antibacterial coating material for bone plates according to the present invention includes a cylinder 2, a hose 8, and a servo motor 5. The cylinder 2 is located at the placement port of the housing 1. The servo motor 5 is located below the housing 1. The output end of the servo motor 5 is connected to a rotating rod 18. An outer cylinder 16 is located at the end of the rotating rod 18 inside the housing 1. An inner cylinder 17 is located inside the outer cylinder 16. A rotating plate 24 is located on the side edge of the rotating rod 18 below the outer cylinder 16. A worm gear 30 is rotatably connected to the rotating plate 24. A fourth gear 31 is located at the input end of the worm gear 30. The fourth gear 31 is meshed with a third gear 19 at the bottom of the housing 1. A worm wheel 29 is connected to one side of the worm gear 30. The output end of the worm wheel 29 is hinged to a linkage frame 26. The linkage frame 26 is hinged to the outer cylinder 16. A storage box 9 is located above the placement end of the outer cylinder 16. The storage box 9 is connected to a storage box 4. A blocking plate 10 is located at the port of the storage box 9. During preparation... First, the polymer is placed inside the inner cylinder 17 of the housing 1. Then, the coupling agent is added to the inside of the housing 1. After addition, the servo motor 5 is started, which drives the rotating rod 18 to rotate. When the rotating rod 18 rotates, it drives the outer cylinder 16 and the inner cylinder 17 to rotate. During the rotation of the rotating rod 18, the rotating plate 24 also rotates. When the rotating plate 24 rotates, it drives the fourth gear 31 to rotate. The fourth gear 31 drives the worm gear 30 to rotate. When the worm gear 30 rotates, it drives the worm wheel 29 to rotate. The worm wheel 29 drives the linkage rod 27 to rotate. When the linkage rod 27 rotates, it drives the linkage frame 26 to rotate. The linkage frame 26 then drives the outer cylinder 16 and the inner cylinder 17 to move up and down. When they move up and down, the polymer will not pile up, so that the coupling agent can come into contact with the polymer more quickly, thereby improving the soaking efficiency.

[0033] like Figure 2 As shown, a first gear 6 is provided on the servo motor 5 at the bottom of the chassis 1. A second gear 7 is meshed with one side of the first gear 6. The second gear 7 is located at the input end of the rotating rod 18. The rotating rod 18 is rotatably connected to the bottom of the base box. One end of the rotating rod 18 is located inside the chassis 1. A vertical groove 21 is provided on the rotating rod 18 inside the chassis 1. By providing the vertical groove 21 on the rotating rod 18, the rotating cylinder 23 on the outer cylinder 16 can be connected in the vertical groove 21. When the outer cylinder 16 moves up and down, it can be achieved by the rotating cylinder 23 moving in the vertical groove 21.

[0034] As an optional solution, in one embodiment of the present invention, such as Figure 3As shown, a rotating cylinder 23 is inserted into the vertical groove 21 of the rotating rod 18. Side frames 22 are connected to the two ends of the rotating cylinder 23 respectively. The rotating cylinder 23 is rotatably connected to the corresponding side frames 22. The side frames 22 on both sides of the rotating rod 18 are respectively set at the bottom of the outer cylinder 16. The diameter of the rotating cylinder 23 between the side frames 22 is the same as the width of the vertical groove 21. The connection between the rotating cylinder 23 and the vertical groove 21 can reduce the friction between them, so that the outer cylinder 16 and the inner cylinder 17 can move more smoothly up and down.

[0035] In implementation, a rotating rod 18 is installed at the bottom of the inner part of the chassis 1. A second gear 7 is connected to the outer end of the rotating rod 18. The second gear 7 meshes with the first gear 6 at the output end of the servo motor 5, which drives the rotating rod 18 to rotate as a whole. An outer cylinder 16 is connected to the rotating rod 18, and an inner cylinder 17 is placed inside the outer cylinder 16. The rotating rod 18 drives the outer cylinder 16 and the inner cylinder 17 to rotate. The polymer to be soaked can be placed inside the inner cylinder 17. The servo motor 5 drives the inner cylinder 17 and the outer cylinder 16 to rotate. The outer cylinder 16 is slidably connected to the corresponding vertical groove 21 of the rotating rod 18 through a rotating cylinder 23. A rotating plate 24 is provided on the rotating rod 18 below the outer cylinder 16. A vertical plate 28 is provided on the rotating plate 24, and a worm gear 30 and a fourth gear 31 can be installed on the rotating plate 24. The fourth gear 31 can mesh with the third gear 19. When the rotating rod 18 rotates, the rotating plate 24 will also rotate. The fourth gear 31 on the rotating plate 24 can rotate under the meshing of the third gear 19. The worm 30 can drive the worm wheel 29 on one side to rotate. The worm wheel 29 can drive the protrusion 25 to rotate through the linkage rod 27. The protrusion 25 can drive the linkage frame 26 to move up and down. When the linkage frame 26 moves up and down, it can push the outer cylinder 16. The outer cylinder 16 can move up and down. The frequency of the up and down movement of the outer cylinder 16 is constant. The outer cylinder 16 can drive the inner cylinder 17 to move vertically. During the movement, the coupling agent can move the polymer in the inner cylinder 17, thereby preventing the polymer from accumulating stably, thus making it easier for the coupling agent to soak, thereby improving efficiency.

[0036] Example 2:

[0037] like Figure 4 and Figure 5As shown, based on Embodiment 1, the present invention provides a technical solution: the third gear 19 inside the chassis 1 is hollow in the middle, and a rotating rod 18 is inserted into the middle of the third gear 19. A rotating plate 24 is connected to the rotating rod 18 above the third gear 19. The rotating plate 24 is parallel to the third gear 19 inside the chassis 1. The end of the rotating plate 24 is connected to the connection between the worm gear 30 and the fourth gear 31. By setting the rotating plate 24, the rotating plate 24 and the rotating rod 18 can rotate synchronously. When the rotating plate 24 rotates, it can drive the fourth gear 31 to rotate along the third gear 19. The worm gear 30 and the fourth gear 31 are T-shaped as a whole. The fourth gear 31 meshes with the third gear 19 inside the chassis 1. A worm wheel 29 is meshed and connected to one side of the worm gear 30. A linkage rod 27 is provided on the 29th plate, and a vertical plate 28 is provided on the corresponding rotating plate 24. The linkage rod 27 is rotatably connected to the corresponding vertical plate 28. The vertical rod can limit the linkage rod 27, allowing it to rotate on the vertical plate 28. A worm gear 29 is provided on one side of the linkage rod 27, and a worm 30 is provided on the other side of the worm gear 29. The worm 30 rotates synchronously with the fourth gear 31. When the fourth gear 31 rotates, it can drive the worm gear 29 to rotate through the worm 30. A protrusion 25 is provided on the other end of the linkage rod 27 on the vertical plate 28. The protrusion 25 on the linkage rod 27 is hinged to the linkage frame 26. A base plate 20 is provided on the outer cylinder 16 corresponding to the linkage frame 26. When the linkage rod 27 rotates, it can drive the linkage frame 26 to move up and down through the protrusion 25.

[0038] As an optional solution, in this embodiment, such as Figure 6 , Figure 7 and Figure 8As shown, the other end of the linkage frame 26 is hinged to the corresponding base plate 20. An annular discharge box 9 is provided above the placement opening of the outer cylinder 16 connected to the base plate 20. An annular blocking plate 10 is provided on the inner wall of the opening of the discharge box 9. The discharge box 9 allows for the storage of deionized water, and the blocking plate 10 blocks the discharge box 9, preventing the outflow of deionized water. A side plate 15 is provided on the blocking plate 10, and a second vertical rod 14 is vertically arranged on the side plate 15. The second vertical rod 14 is located on the top plate 3, and the side plate 15 is located on the inner wall of the blocking plate 10, providing support for the second vertical rod 14. A horizontal frame 12 is slidably connected to the second vertical rod 14, and the horizontal frame 12 is perpendicularly connected to the second vertical rod 14. A first vertical rod 11 is provided on the other end of the frame 12. The first vertical rod 11 is connected to the corresponding box 9. The horizontal frame 12 can move up and down along the second vertical rod 14 through the horizontal frame 12. The horizontal frame 12 can move up and down under the drive of the first vertical rod 11. The height of the first vertical rod 11 on the box 9 is lower than the height of the second vertical rod 14 on the blocking plate 10. A first spring 13 is provided below the horizontal frame 12 connected to the first vertical rod 11. The first spring 13 is located on the second vertical rod 14 below the horizontal frame 12. The two ends of the first spring 13 are connected to the horizontal frame 12 and the side plate 15 respectively. The horizontal frame 12 can be pulled by the first spring 13. The box 9 can be reset when it is not pushed by the rotating cylinder 23.

[0039] In implementation, a cylinder 2 is installed at the placement port of the casing 1. The cylinder 2 can drive the top plate 3 to rise and fall, facilitating the loading and unloading of polymers. A storage tank 4 is installed on the top plate 3, which stores deionized water. After the polymer soaking is completed, the coupling agent can be discharged first. After discharge, the cylinder 2 can move the top plate 3 to a certain position, and then the servo motor 5 is started. The servo motor 5 can then drive the inner cylinder 17 and the outer cylinder 16 to rotate again. When the inner cylinder 17 and the outer cylinder 16 rotate, they will move up and down. When the inner cylinder 16 and inner cylinder 17 move upward, they will push the discharge box 9. The discharge box 9 will then move upward along the second vertical rod 14 via the horizontal frame 12. When the discharge box 9 moves upward, the internal opening will not be blocked, and deionized water can fall onto the polymer in the inner cylinder 17 through the discharge box 9, thereby cleaning the polymer. During the up and down movement of the inner cylinder 17, polymer accumulation can be prevented, so that the deionized water can clean the polymer evenly. This eliminates the need to move the polymer to other equipment for cleaning, thus speeding up the polymer preparation process.

[0040] The working principle of this invention is as follows: A rotating rod 18 is installed at the bottom of the inner part of the casing 1. A second gear 7 is connected to the outer end of the rotating rod 18. The second gear 7 meshes with the first gear 6 at the output end of the servo motor 5, so the servo motor 5 can drive the rotating rod 18 to rotate as a whole. An outer cylinder 16 is connected to the rotating rod 18, and an inner cylinder 17 is placed inside the outer cylinder 16. The rotating rod 18 can drive the outer cylinder 16 and the inner cylinder 17 to rotate. The polymer to be soaked can be placed inside the inner cylinder 17. The servo motor 5 can drive the inner cylinder 17 and the outer cylinder 16 to rotate. The outer cylinder 16 is slidably connected to the corresponding vertical groove 21 of the rotating rod 18 through a rotating cylinder 23. Below the outer cylinder 16... A rotating plate 24 is provided on the rotating rod 18, and a vertical plate 28 is provided on the rotating plate 24. The worm gear 30 and the fourth gear 31 can be installed on the rotating plate 24. The fourth gear 31 can mesh with the third gear 19. When the rotating rod 18 rotates, the rotating plate 24 also rotates. The fourth gear 31 on the rotating plate 24 can rotate under the meshing of the third gear 19. The worm gear 30 can drive the worm wheel 29 on one side to rotate. The worm wheel 29 can drive the protrusion 25 to rotate through the linkage rod 27. The protrusion 25 can drive the linkage frame 26 to move up and down. When the linkage frame 26 moves up and down, it can push the outer cylinder 16, so that the outer cylinder 16 can move up and down. At a constant frequency, the outer cylinder 16 can drive the inner cylinder 17 to move vertically. During the movement, the coupling agent can move the polymer inside the inner cylinder 17, thereby preventing the polymer from accumulating and facilitating the soaking of the coupling agent, thus improving efficiency. A cylinder 2 is installed at the placement port of the housing 1, which can drive the top plate 3 to rise and fall. The rise and fall of the top plate 3 facilitates the loading and unloading of polymers. A storage tank 4 is installed on the top plate 3, which stores deionized water. After the polymer soaking is complete, the coupling agent can be discharged first. After discharge, the top plate 3 can be moved to a certain position by the cylinder 2, and then the servo motor 5 is started. This allows the inner cylinder 17 and outer cylinder 16 to rotate again. When the inner cylinder 17 and outer cylinder 16 rotate, they will move up and down. When the outer cylinder 16 and inner cylinder 17 move upward, they will push the discharge box 9. The discharge box 9 will then move upward along the second vertical rod 14 via the horizontal frame 12. When the discharge box 9 moves upward, the internal opening will not be blocked, and deionized water can fall onto the polymer in the inner cylinder 17 through the discharge box 9, thereby cleaning the polymer. During the up and down movement of the inner cylinder 17, polymer accumulation can be prevented, so that the deionized water can clean the polymer evenly. This eliminates the need to move the polymer to other equipment for cleaning, thus speeding up the polymer preparation process.
