Description

Technical Field

[0001] The present invention relates to the technical field of dental implant treatment, and particularly relates to a sandblasting medium treatment device and a recycling method for implant surface treatment. Background Art

[0002] An implant, commonly known as an artificial tooth root, is a part that replaces the natural tooth to perform chewing functions in the jawbone. It is implanted into the jawbone of the human body through a surgical operation using materials with good tissue compatibility (such as titanium, titanium alloy, bioceramics, etc.) to replace the missing natural tooth, mainly playing a fixing role, and can support the upper prosthesis (such as a dental crown), thereby restoring the chewing, aesthetic and other functions of the patient.

[0003] During the production process of implants, sandblasting treatment is required. Through sandblasting treatment, holes equivalent to bone lacunae can be formed on the surface of the implant, increasing the surface roughness. This helps to promote the adhesion and proliferation of osteoblasts. At the same time, by increasing the surface roughness of the implant, the bonding ability between the implant and bone tissue can be significantly improved, thereby enhancing the stability and long-term effect of the implant.

[0004] Existing equipment for implant sandblasting generally uses a sandblasting machine, which mainly consists of an air purifier, an air compressor, a buffer tank, a machine body, a nozzle, a sand tank, etc. Its working principle is to use clean compressed air as power to spray abrasives at high speed onto the surface of the metal implant material, causing changes in its appearance, shape and surface properties. In actual operation, the sandblasting machine will spray abrasives with a certain particle size onto the implant surface at a set angle and distance under the drive of the set air pressure and flow rate.

[0005] During the use of the sandblasting machine, there are still deficiencies. For example: after the sandblasting machine uses the sandblasting medium for sandblasting, its size will change with the collision with the metal surface of the implant. However, there are still a large number of sandblasting media in these sandblasting media that meet the requirements for sandblasting the implant surface. And these used sandblasting media generally need to be subjected to subsequent separate treatment and cannot be reused immediately. Thus, during the process of implant surface treatment, new sandblasting media need to be continuously added, which will increase the sandblasting cost of the implant. Summary of the Invention

[0006] Aiming at the problems in the background art, a sandblasting medium treatment device and a recycling method for implant surface treatment are proposed.

[0007] The present invention provides a sandblasting medium treatment device for implant surface treatment, including a sandblasting machine. An inlet pipe 1 and an outlet pipe 1 are arranged on the sandblasting machine, which are used to input the sandblasting medium into the sandblasting machine and discharge the used sandblasting medium. A medium treatment mechanism is arranged on one side of the sandblasting machine. The medium treatment mechanism consists of a housing, a vibration motor, and a filter plate. The vibration motor is installed on the housing and is used to drive the housing to vibrate. The filter plate is installed on the housing and is used to vibrate with the housing. Multiple filter holes are formed on the filter plate, which are used to filter the medium.

A track groove is formed on the track rod, and the track groove is spiral. The track rod penetrates through the through hole 1 and is slidably connected to the inner wall of the through hole 1. The ball extends into the track groove and contacts the inner wall of the track groove. When the adjusting plate 1 rises, the rotating block moves upward accordingly. Under the action of the track groove and the ball, the rotating block rotates when moving upward, thereby driving the straight rod to rotate.

[0010] Preferably, a finishing strip is installed on the filter plate. The top of the finishing strip is inclined. The finishing strip is hollow. When the sandblasting medium moves on the filter plate, the finishing strip will slow down the movement of the sandblasting medium, and when the sandblasting medium breaks away from the finishing strip, it will fall a short distance and collide with the filter plate, thereby colliding and dispersing the sandblasting medium.

[0011] Preferably, a partition frame is installed on the outer shell, a T-shaped push plate is installed on the second adjusting plate, the T-shaped push plate extends into the partition frame and is slidably connected to the inner wall of the partition frame, an adjusting airbag is installed in the partition frame, the outer side of the adjusting airbag is connected to the bottom inner wall of the partition frame and the bottom of the T-shaped push plate, a gas distribution frame is installed on the outer shell, a gas guide hole is opened on the outer shell, the gas guide hole is communicated with the gas distribution frame, the gas guide hole is communicated with the finishing strip, a gas guide pipe is installed on the adjusting airbag, the gas guide pipe is communicated with the gas distribution frame, an air inlet pipe is installed on the gas guide pipe, one-way valves are arranged on both the air inlet pipe and the gas guide pipe, the air flow input and output in the adjusting airbag can be controlled through the one-way valves, a first air hole is opened on the finishing strip, a return spring is installed on the partition frame, the return spring is connected to the T-shaped push plate, and during the up and down movement of the second adjusting plate, the adjusting airbag will be indirectly driven to contract and expand, thereby providing air flow in the finishing strip, and the air flow acts on the sandblasting medium to improve the effect of dispersing the sandblasting medium.

[0012] Preferably, an adjusting through groove is opened on the outer shell, a connecting block is installed on the second adjusting plate, the connecting block penetrates through the adjusting through groove and is slidably connected to the adjusting through groove, a gear rack is installed on the outer shell, the gear rack is connected to the connecting block, an adapter is rotatably installed on the outer shell, an annular rack is arranged on the adapter, the annular rack is meshed and connected with the gear rack, a material limiting roller is rotatably installed on the outer shell, one end of the material limiting roller extends outside the outer shell, and a pulley is sleeved on one end of the material limiting roller, a transmission belt is sleeved on the pulley, the transmission belt is sleeved on the adapter, and during the up and down movement of the second adjusting plate, the gear rack is driven to move, then the adapter is driven to rotate, and then the material limiting roller is driven to rotate through the transmission belt and the pulley, so as to avoid the blockage of the sandblasting medium feeding.

[0013] Preferably, a weight sensor is arranged on the outer shell for monitoring the capacity of the sandblasting medium, and when the capacity is insufficient, new sandblasting medium is input into the outer shell.

[0014] Preferably, a rubber sleeve is sleeved on the straight rod, and the rubber sleeve is in contact with the inner wall of the filtering hole for cleaning the inner wall of the filtering hole during the rotation of the straight rod.

When the weight of the sandblasting medium is lower than the standard, that is, the capacity of the sandblasting medium is lower than the requirement, new sandblasting medium is transported into the housing through the feeding hopper to ensure the usage requirements of the sandblaster.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: During the use of the sandblasting medium treatment device for implant surface treatment, by setting the first vacuum feeding pump and the second vacuum feeding pump, the sandblasting medium after the sandblasting operation can be transported into the housing for filtration, and the medium that meets the sandblasting requirements can be re-transported into the sandblaster for reuse, thereby saving the sandblasting cost; By setting the adjusting cylinder to drive the first adjusting plate and the second adjusting plate to move up and down, and then drive the straight rod to move, the filter holes on the filter plate can be prevented from being blocked.

A medium treatment mechanism is arranged on one side of the sandblasting machine 1. The medium treatment mechanism is composed of a housing 2, a vibration motor and a filter plate 3. The vibration motor is installed on the housing 2 and is used to drive the housing 2 to vibrate. The filter plate 3 is installed on the housing 2 and is used to vibrate with the housing 2. A support frame is arranged below the housing 2, and the support frame is connected to the housing 2 through vibration springs. When the vibration motor works, the housing 2 will rotate accordingly to ensure the filtering effect of the filter plate 3 on the sandblasting medium; multiple filter holes are opened on the filter plate 3 for filtering the medium, and the multiple filter holes are divided into multiple groups according to the inner diameter size, and the inner diameter size of each group is different, used to separate sandblasting media of different sizes. Multiple collection parts are arranged in the housing 2, and the multiple collection parts are respectively located below the corresponding multiple groups of filter holes, used to collect sandblasting media of corresponding sizes. Among them, a weight sensor is arranged on the housing 2, and the weight sensor is located below the collection part for sandblasting medium that meets the requirements. The weight sensor is composed of existing technology and is used to detect the weight of the sandblasting medium in the collection part, and then monitor the capacity of the sandblasting medium in the collection part. When the capacity in the collection part for collecting sandblasting medium that meets the requirements is insufficient, new sandblasting medium can be input into the collection part through the feeding hopper 10 to ensure the normal working requirements of the sandblasting machine 1. And discharge frames are arranged on the other collection parts for collecting sandblasting media, used to discharge sandblasting media; a first vacuum feeding pump 4 and a second vacuum feeding pump 5 are arranged on the housing 2. The first vacuum feeding pump 4 is communicated with the first discharge pipe 7, and a second feed pipe 8 is installed on the first vacuum feeding pump 4, used to transport the used sandblasting medium on the sandblasting machine 1 into the housing 2. The second vacuum feeding pump 5 is communicated with the first feed pipe 6, and a second discharge pipe 9 is installed on the second vacuum feeding pump 5. The second discharge pipe 9 is communicated with the housing 2, used to transport the sandblasting medium that still meets the regulations after screening into the sandblasting machine 1 and continue to be used for the sandblasting operation of the implant; a feeding hopper 10 is installed on the housing 2, used to add new sandblasting medium into the housing 2, and a baffle is hinged on the housing 2, used to block the top opening of the feeding hopper 10.

[0020] An adjusting plate 11 and an adjusting plate 12 are slidably installed on the housing 2. The adjusting plate 11 is located above the adjusting plate 12. Multiple material leakage grooves are opened on the adjusting plate 12. An adjusting cylinder 16 is installed on the housing 2. The telescopic shaft of the adjusting cylinder 16 is connected to the top of the adjusting plate 11. A straight rod 13 is arranged on the adjusting plate 11. The straight rod 13 penetrates through the filter hole and is connected to the adjusting plate 12. When the filter plate 3 filters the sandblasting medium, the adjusting cylinder 16 drives the adjusting plate 11 to rise, and then drives the straight rod 13 to move. Through the up and down movement of the straight rod 13, the blockage of the filter hole can be avoided.

[0021] Rotating blocks 14 are rotatably mounted on both the first adjusting plate 11 and the second adjusting plate 12. Both ends of the straight rod 13 are connected to the two rotating blocks 14 respectively. A track rod 15 is mounted on the outer shell 2. A through hole one is formed in the rotating block 14 located on the first adjusting plate 11. Ball beads are arranged on the inner wall of the through hole one. A track groove is formed in the track rod 15. The track groove is spiral. The track rod 15 penetrates through the through hole one and is slidably connected to the inner wall of the through hole one. The ball beads extend into the track groove and contact the inner wall of the track groove. When the first adjusting plate 11 rises, the rotating block 14 moves upward accordingly. Under the action of the track groove and the ball beads, the rotating block 14 rotates when moving upward, thereby driving the straight rod 13 to rotate. A rubber sheath is sleeved on the straight rod 13. The rubber sheath contacts the inner wall of the filter hole and is used to clean the inner wall of the filter hole during the rotation of the straight rod 13. By providing the rubber sheath, the straight rod 13 can be prevented from directly contacting the filter hole, damage to the straight rod 13 can be avoided, and at the same time, the rubber sheath can reduce hard extrusion and reduce wear on the filter hole.

[0022] A sorting strip 22 is mounted on the filter plate 3. The top of the sorting strip 22 is inclined. The sorting strip 22 is hollow. When the sandblasting medium moves on the filter plate 3, the sorting strip 22 will slow down the movement of the sandblasting medium, and when the sandblasting medium detaches from the sorting strip 22, it will fall a short distance and collide with the filter plate 3, thereby colliding and dispersing the sandblasting medium. A partition frame 17 is mounted on the outer shell 2. A T-shaped push plate 18 is mounted on the second adjusting plate 12. The T-shaped push plate 18 extends into the partition frame 17 and is slidably connected to the inner wall of the partition frame 17. An adjusting airbag 19 is mounted in the partition frame 17. The outside of the adjusting airbag 19 is connected to the bottom inner wall of the partition frame 17 and the bottom of the T-shaped push plate 18. A gas distribution frame 20 is mounted on the outer shell 2. An air guide hole is formed in the outer shell 2. The air guide hole is communicated with the gas distribution frame 20. The air guide hole is communicated with the sorting strip 22. An air guide pipe 21 is mounted on the adjusting airbag 19. The air guide pipe 21 is communicated with the gas distribution frame 20. An air inlet pipe is mounted on the air guide pipe 21. One-way valves are arranged on both the air inlet pipe and the air guide pipe 21. The one-way valve on the air inlet pipe can only input air into the adjusting airbag 19, and the one-way valve on the air guide pipe 21 can only input air into the gas distribution frame 20. The air flow input and output in the adjusting airbag 19 can be controlled through the one-way valve. An air hole one is formed in the sorting strip 22. The air hole one is arranged at an inclined upward angle, so that the air flow blows the sandblasting medium upward during the process of discharging through the air hole one. A return spring is mounted on the partition frame 17. The return spring is connected to the T-shaped push plate 18. During the up and down movement of the second adjusting plate 12, the adjusting airbag 19 will be indirectly driven to contract and expand, thereby providing air flow for the sorting strip 22. The air flow acts on the sandblasting medium to improve the effect of dispersing the sandblasting medium.

[0023] An adjustment through slot is provided on the outer shell 2. A connecting block is installed on the second adjusting plate 12. The connecting block penetrates through the adjustment through slot and is slidably connected to the adjustment through slot. A toothed bar 23 is installed on the outer shell 2. The toothed bar 23 is connected to the connecting block. An adapter 24 is rotatably installed on the outer shell 2. An annular toothed rack is provided on the adapter 24. The annular toothed rack is meshed and connected to the toothed bar 23. A material limiting roller 25 is rotatably installed on the outer shell 2. One end of the material limiting roller 25 extends outside the outer shell 2, and a pulley is sleeved on this end of the material limiting roller 25. A transmission belt 26 is sleeved on the pulley. The transmission belt 26 is sleeved on the adapter 24. During the up and down movement of the second adjusting plate 12, the toothed bar 23 is driven to move, and then the adapter 24 is driven to rotate. Then, the material limiting roller 25 is driven to rotate through the transmission belt 26 and the pulley, avoiding the blockage of the sandblasting medium feeding. A shielding plate 27 is installed on the outer shell 2. The shielding plate 27 is located above the material limiting roller 25 and is in contact with the outer side of the material limiting roller 25. Through the shielding plate 27, the outer wall of the material limiting roller 25 can be cleaned during the reverse rotation of the material limiting roller 25, ensuring the cleanliness of the outer wall of the material limiting roller 25 and avoiding the adhesion of the sandblasting medium on the outer wall of the material limiting roller 25, which affects the uniformity of the sandblasting medium flowing to the filter plate 3.

[0024] In this embodiment, during use, the implant is sandblasted by the sandblasting machine 1. The sandblasting medium after the sandblasting operation is transported into the outer shell 2 through the vacuum feeding pump 1, the discharge pipe 1 and the feeding pipe 2. The sandblasting medium is filtered by the filter plate 3. The filtered sandblasting medium respectively falls into the lower collecting parts. Among them, the sandblasting medium meeting the sandblasting requirements is re-transported into the sandblasting machine 1 through the vacuum feeding pump 2, the discharge pipe 2 and the feeding pipe 1 for the next sandblasting operation. Thus, the cost of the sandblasting medium can be saved. And through the weight sensor, the capacity of the sandblasting medium in the collecting parts can be monitored. When the capacity is low, new sandblasting medium can be input into the collecting parts through the feeding hopper 10, thus ensuring the sandblasting requirements of the sandblasting machine 1. During the process of filtering the sandblasting medium, the adjusting cylinder 16 can be started to drive the first adjusting plate 11 to move up and down. Thus, the straight rod 13 and the second adjusting plate 12 can be indirectly driven to move up and down. During the up and down movement of the straight rod 13, the sandblasting medium can be prevented from getting stuck in the filter holes on the filter plate 3, causing blockage, and ensuring the filtering effect of the filter plate 3 on the sandblasting medium. At the same time, under the action of the track rod 15, during the rising process of the first adjusting plate 11, the rotating block 14 can be driven to rotate through the track groove and the ball, thereby driving the straight rod 13 to rotate, making the straight rod 13 in a rotating state inside the filter hole. Under the action of the rubber sleeve, the inner wall of the filter hole can be cleaned. In this way, the cleanliness of the filter plate 3 can be ensured, and the sandblasting medium can be prevented from remaining on the filter plate 3, causing pollution. During the up-and-down movement of the second regulating plate 12, the T-shaped push plate 18 will be driven to move, thereby driving the expansion or contraction of the regulating airbag 19. When contracting, the air will be agitated and flow through the air duct 21 and the air distribution frame 20 into the finishing strip 22, and then act on the abrasive media on the filter plate 3 through a plurality of first air holes. Under the combined action of the finishing strip 22, the abrasive media moving on the filter plate 3 will be dispersed to ensure the filtering effect of the abrasive media. At the same time, during the up-and-down movement of the second regulating plate 12, the toothed bar 23 can be driven to move through the connecting block. Under the action of the connecting piece 24 and the transmission belt 26, the material-limiting roller 25 is driven to rotate, thus preventing the abrasive media from being blocked at the material-limiting roller 25. Through the action of the material-limiting roller 25, the abrasive media can be limited in quantity, so that it is in a uniformly paved state before flowing to the filter plate 3, ensuring the subsequent filtering effect.

[0025] A method for recycling abrasive media for implant surface treatment proposed by the present invention includes the following steps: S1: The abrasive media is sprayed onto the implant through a nozzle to perform sandblasting on the surface of the implant. After the abrasive media contacts the surface of the implant, it falls into the collection device of the sandblaster 1. S2: Start the first vacuum transfer pump 4, and discharge the waste abrasive media in the sandblaster 1 above the filter plate 3 in the housing 2 through the first discharge pipe 7 and the second feed pipe 8. S3: Start the vibration motor to drive the housing 2 to vibrate, indirectly drive the filter plate 3 to vibrate, and the abrasive media moves on the filter plate 3, and the abrasive media is filtered through the filter holes. S4: Start the second vacuum transfer pump 5, and re-transport the filtered abrasive media meeting the sandblasting requirements through the second discharge pipe 9 and the first feed pipe 6 into the sandblaster 1 for reuse, thereby completing the recycling of the abrasive media. S5: Use the weight sensor to measure the abrasive media meeting the sandblasting requirements in the housing 2. When the weight of the abrasive media is lower than the standard, that is, the capacity of the abrasive media is lower than the requirement, new abrasive media is transported into the housing 2 through the feeding hopper 10 to ensure the use requirements of the sandblaster 1.

[0026] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art to which the present invention pertains.
