Description

TECHNICAL FIELD

[0001] The present application relates to the field of allogeneic bone material production, and particularly relates to a swing type drying device for allogeneic bone implant material production. BACKGROUND

[0002] Allogeneic bone is the most commonly used bone implant material in orthopedics at present, and is mainly used for repairing and filling bone defects, playing a role of fixation and support. The range of clinical application of allogeneic bone can include almost all indications of various implant materials.

[0003] At present, the existing allogeneic bone spin-drying device (such as patent No. CN211637499U) discloses a cleaning and spin-drying device for allogeneic bone implant material in orthopedics. The device has a filter barrel, which can realize the lifting of the filter barrel through a rotating handle, effectively facilitating the taking of the allogeneic bone implant material. The device has a water outlet pipe, which can effectively clean the allogeneic bone implant material. The device has a filter barrel, which can realize the rotation of the filter barrel, effectively spin-drying the allogeneic bone implant material.

[0004] The above technical solution has the following disadvantages: (1) the existing spin-drying device directly places the allogeneic bone implant material in the spin-drying barrel for spin-drying. During the spin-drying process, the allogeneic bone implant materials will collide with each other, causing some fragile or small allogeneic bone implant materials to be abraded or even damaged, affecting the subsequent use of the allogeneic bone implant materials; (2) the existing spin-drying device directly places the allogeneic bone implant material in the spin-drying barrel for spin-drying. During the spin-drying process, the allogeneic bone implant materials will continuously hit the barrel wall, which will cause certain abrasion and damage to the barrel body over a long period of time; (3) the existing spin-drying device only relies on the barrel body to rotate for spin-drying, which has a low spin-drying efficiency, and the allogeneic bone implant materials are stacked together, which may cause incomplete spin-drying.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This device uses a feeding component, a feeding trough, and multiple drying tubes in combination. During feeding, the chassis drives each drying tube to rotate, and multiple conical teeth drive the feeding component to rotate inside the discharge tube, so that the allogeneic bone implant material is evenly fed into each drying tube. This allows the allogeneic bone implant material to be arranged in the drying tube. When leakage occurs, the allogeneic bone implant material is separated to facilitate subsequent spin drying.

[0012] 2. This device confines the arrangement of allogeneic bone implant materials within each drying tube, avoiding severe collisions between the allogeneic bone implant materials during the spin-drying process, preventing wear and damage to the relatively fragile allogeneic bone implant materials, and ensuring the production quality of the allogeneic bone implant materials.

[0013] 3. This device distributes the allogeneic bone implant material in multiple drying tubes to prevent the allogeneic bone implant material from piling up during spin drying, which would result in incomplete spin drying and affect the efficiency of spin drying.

[0014] 4. This device is equipped with a first gear and a second gear that work together. When the chassis drives each drying tube to rotate around the drive shaft, each first gear rotates around the drive shaft and rotates on its own axis under the action of the second gear. The drying tubes rotate on their own axis while rotating around the drive shaft, thus performing double rotation and spin drying, thereby improving the spin drying efficiency of allogeneic bone implant materials.

[0015] 5. This device confines the allogeneic bone implant material within the drying tube for spin drying, preventing the allogeneic bone implant material from colliding with the inner wall of the spin drying drum during spin drying, thus extending the service life of the spin drying drum.

[0016] 6. This device is equipped with a height-adjustable second gear. When feeding materials, the second gear can be adjusted upwards and not engage with each of the first gears. When spinning and drying, the second gear can be adjusted downwards and engage with each of the first gears to adapt to different working processes. It has high adaptability and is simple and quick to adjust. Attached Figure Description

A second conical tooth 32 is fixedly installed on the circumferential end of the drive shaft 31. A second movable column 33 is rotatably installed on the inner side wall of the second rotating groove 18.

A fifth conical tooth 37 is fixedly installed on the circumferential end of the first movable column 36. The fifth conical tooth 37 meshes with the third conical tooth 34. A fifth conical tooth 37 is fixedly installed on the circumferential end of the first movable column 36 on the side away from the fifth conical tooth 37. A sixth conical tooth 38 is fixedly installed at the circumferential end, and the sixth conical tooth 38 meshes with the first conical tooth 26. After cleaning the allogeneic bone implant material, the user needs to spin-dry it. The user can put the cleaned allogeneic bone implant material into the storage tank 2. After feeding the allogeneic bone implant material into the storage tank 2, the user can start the motor 3. The motor 3 starts and drives the transmission shaft 31 to rotate at a constant speed. The rotation of the transmission shaft 31 drives the chassis 41 to rotate. The rotation of the chassis 41 drives the spin-drying tank 4 to rotate. The rotation of the chassis 41 drives each rotating shaft 45 to rotate through the cylindrical groove 42. The rotation of each rotating shaft 45 drives each drying tube 46 to rotate. When the transmission shaft 31 rotates, it will drive the second conical tooth 32 to rotate.The rotation of the second conical tooth 32 drives the rotation of the fourth conical tooth 35. The rotation of the fourth conical tooth 35, through the second movable column 33, drives the rotation of the third conical tooth 34. The rotation of the third conical tooth 34 drives the rotation of the fifth conical tooth 37. The rotation of the fifth conical tooth 37 drives the rotation of the first movable column 36. The rotation of the first movable column 36 drives the rotation of the sixth conical tooth 38. The rotation of the sixth conical tooth 38 drives the rotation of the first conical tooth 26. The rotation of the first conical tooth 26 drives the connecting rod 25 to rotate within the circular groove 22. The rotation of the connecting rod 25 drives the feeding component 23 to rotate. The allogeneic bone implant material in the storage tank 2... The material falls into the feeding trough 24. When the feeding component 23 rotates, it drives the allogeneic bone implant material in the feeding trough 24 into the feeding hopper 61, and then into the drying tube 46. When the spin-drying tank 4 rotates each drying tube 46 to below the feeding hopper 61, the feeding component 23 drives the feeding trough 24 to rotate downwards. This process is repeated to ensure that the allogeneic bone implant material in the feeding trough 24 is fed into each drying tube 46, thus evenly distributing the allogeneic bone implant material in the storage tank 2 into each drying tube 46.

[0029] The drying mechanism includes drying tubes 46, fixing posts 5, and a lid 6. The lid 6 is fitted onto the upper end of the spin-drying tub 4, and a threaded groove 62 is formed through the upper end of the lid 6. A feed hopper 61 is fixedly installed on the upper end of the lid 6. A threaded rod 51 is fixedly installed on the upper end of the fixing post 5. The threaded rod 51 is rotatably mounted on the inner wall of the threaded groove 62. After feeding, the allogeneic bone implant material is evenly arranged on the inner wall of each drying tube 46. At this time, the user can rotate the threaded rod 51, as the threads on the threaded rod 51 and the threaded groove 62 are engaged. The threaded rod 51 rotates and moves downward within the threaded groove 62. The downward movement of the threaded rod 51 drives the disc 52 to move downward, which in turn drives the second gear 53 to move downward. The two second gears 53, limited by the two telescopic rods 54, will not rotate with the disc 52. When the second gears 53 move downward, they will mesh with each of the first gears 43. At this time, the telescopic rods 54 retract. When adjusting the downward movement of the second gears 53 to mesh with each of the first gears 43, the user can stop rotating the threaded rod 51.

[0030] The upper end of the chassis 41 has at least two cylindrical grooves 42. There are at least two drying tubes 46. A rotating shaft 45 is fixedly installed at the lower end of each drying tube 46. Each rotating shaft 45 is rotatably mounted on the inner wall of the cylindrical groove 42. At least two water-spraying nozzles 47 are equidistantly arranged on all four sides of each drying tube 46. A first gear 43 is fixedly installed at the circumferential end of each rotating shaft 45. A disc 52 is fixedly installed at the lower end of the threaded rod 51. A second gear 53 is rotatably installed at the circumferential end of the disc 52. Each first gear 43 meshes with a second gear 53. Two telescopic rods 54 are fixedly installed between the second gear 53 and the chassis 41. When adjusting the second gear 53 to move downwards and mesh with each first gear 43, the user can restart the motor 3. The motor 3 starts and drives the transmission shaft 31 to rotate. The rotation drives the chassis 41 to rotate, and the chassis 41 drives each drying tube 46 to rotate around the drive shaft 31 via the cylindrical groove 42. This allows the drying tube 46 to rotate and dry the allogeneic bone implant material. While each rotating shaft 45 rotates around the drive shaft 31, it also drives each first gear 43 to rotate around the drive shaft 31. Since each first gear 43 meshes with the second gear 53 and the second gear 53 is in a stationary rotating state, each first gear 43 will rotate on its own axis under the drive of the second gear 53 when it rotates around the drive shaft 31. The rotation of the first gear 43 drives the rotating shaft 45 to rotate, and the rotation of the rotating shaft 45 drives the drying tube 46 to rotate. This allows each drying tube 46 to rotate on its own axis while revolving around the drive shaft, thus drying the allogeneic bone implant material inside the drying tube 46. Excess water is thrown out through the water outlet 47 and discharged through the drain pipe 48 on the fixed base 1.

[0031] Working principle:

[0032] The first step involves the user cleaning the allogeneic bone implant material and then spin-drying it. The user places the cleaned material into the storage tank 2. The user then starts the motor 3, which drives the drive shaft 31 to rotate at a constant speed. The rotation of the drive shaft 31 drives the chassis 41, which in turn drives the spin-drying drum 4. The chassis 41's rotation, via the cylindrical groove 42, drives each rotating shaft 45, which in turn drives each drying tube 46. The rotation of the drive shaft 31 drives the second conical tooth 32, which in turn drives the fourth conical tooth 35. The fourth conical tooth 35's rotation, via the second movable column 33, drives the third conical tooth 34, which in turn drives the fifth conical tooth 37. The first movable column 36 is driven to rotate, which in turn drives the sixth conical tooth 38 to rotate, which in turn drives the first conical tooth 26 to rotate, which in turn drives the connecting rod 25 to rotate in the circular groove 22, and the rotating connecting rod 25 drives the feeding component 23 to rotate. The allogeneic bone implant material in the storage tank 2 will fall into the feeding trough 24. When the feeding component 23 rotates, it will drive the allogeneic bone implant material in the feeding trough 24 to be fed into the feeding hopper 61, and then enter the drying tube 46 through the feeding hopper 61. When the spin dryer 4 drives each drying tube 46 to rotate below the feeding hopper 61, the feeding component 23 drives the feeding trough 24 to rotate downward. This process is repeated to realize that the rotation of the feeding component 23 drives the allogeneic bone implant material in the feeding trough 24 to be fed into each drying tube 46, so as to evenly feed the allogeneic bone implant material in the storage tank 2 into each drying tube 46.

[0033] The second step involves placing the allogeneic bone implant material evenly on the inner wall of each drying tube 46 after feeding. The user can then rotate the threaded rod 51. Because the thread and the groove 62 on the threaded rod 51 are engaged, the threaded rod 51 rotates and moves downward within the groove 62. This downward movement of the threaded rod 51 causes the disc 52 to move downward, which in turn causes the second gear 53 to move downward. The two second gears 53, limited by the two telescopic rods 54, will not rotate with the disc 52. As the second gears 53 move downward, they will mesh with each of the first gears 43. At this point, the telescopic rods 54 retract. When adjusting the downward movement of the second gears 53 to mesh with each of the first gears 43, the user can stop rotating the threaded rod 51.

[0034] Thirdly, when adjusting the second gear 53 to move downwards and mesh with each of the first gears 43, the user can restart the motor 3. The motor 3 starts, driving the transmission shaft 31 to rotate. The rotation of the transmission shaft 31 drives the chassis 41 to rotate. The chassis 41, through the cylindrical groove 42, drives each drying tube 46 to rotate around the transmission shaft 31, thus achieving the drying of the allogeneic bone implant material by rotating the drying tubes 46. Simultaneously, the rotation of each rotating shaft 45 around the transmission shaft 31 drives each of the first gears 43 to rotate around the transmission shaft 31. Because each of the first gears... All gears 43 mesh with the second gear 53, and the second gear 53 is in a stationary rotating state. When each first gear 43 rotates around the transmission shaft 31, it will rotate under the drive of the second gear 53. The rotation of the first gear 43 drives the rotation of the shaft 45, and the rotation of the shaft 45 drives the rotation of the drying tube 46. In this way, each drying tube 46 rotates while revolving, which dries the allogeneic bone implant material in the drying tube 46. Excess water is thrown out through the water outlet 47 and discharged through the drain pipe 48 on the fixed base 1.
