Description

Technical Field

[0001] This invention relates to the field of dental implant treatment technology, and more particularly to a sandblasting media treatment device and circulation method for implant surface treatment. Background Technology

[0002] Implants, commonly known as artificial tooth roots, are parts of the jawbone that replace natural teeth to perform chewing functions. They are implanted into the jawbone through surgery using materials with good tissue compatibility (such as titanium, titanium alloys, bioceramics, etc.) to replace missing natural teeth. They mainly serve a fixing function, supporting the upper restoration (such as a crown), thereby restoring the patient's chewing, aesthetic and other functions.

[0003] During the production of implants, they need to be sandblasted. Sandblasting can create pores on the implant surface that are similar to bone lacunae, increasing the surface roughness. This helps promote the adhesion and proliferation of osteoblasts. At the same time, by increasing the roughness of the implant surface, the ability of the implant to integrate with bone tissue can be significantly improved, thereby enhancing the stability and long-term effect of the implant.

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

[0005] There are still shortcomings in the use of sandblasting machines. For example, after the sandblasting machine uses sandblasting media, its size will change due to the collision with the metal surface of the implant. However, there is still a large amount of sandblasting media that is suitable for sandblasting the surface of the implant. These used sandblasting media generally need to be processed separately and cannot be reused in time. Therefore, during the surface treatment of the implant, new sandblasting media needs to be added continuously, which increases the cost of sandblasting the implant. Summary of the Invention

[0006] To address the problems existing in the background technology, a sandblasting media treatment device and circulation method for implant surface treatment are proposed.

[0007] This invention proposes a sandblasting media treatment device for implant surface treatment, including a sandblasting machine. The sandblasting machine is equipped with an inlet pipe and an outlet pipe for inputting sandblasting media into the sandblasting machine and discharging used sandblasting media. A media treatment mechanism is provided on one side of the sandblasting machine. The media treatment mechanism consists of a shell, a vibration motor, and a filter plate. The vibration motor is mounted on the shell to drive the shell to vibrate. The filter plate is mounted on the shell to follow the vibration of the shell. The filter plate has multiple filter holes for filtering the media. The multiple filter holes are divided into multiple groups according to their inner diameter, and each group has a different inner diameter to separate sandblasting media of different sizes. The outer casing is equipped with a vacuum feed pump 1 and a vacuum feed pump 2. Vacuum feed pump 1 is connected to discharge pipe 1 and has a feed pipe 2 installed on it. It is used to transport the sandblasting medium used in the sandblasting machine into the outer casing. Vacuum feed pump 2 is connected to feed pipe 1 and has a discharge pipe 2 installed on it. The discharge pipe 2 is connected to the outer casing and is used to transport the sandblasting medium that still meets the specifications after screening into the sandblasting machine for continued use in the sandblasting operation of the implant. A feeding hopper is installed on the outer casing for adding new sandblasting medium into the outer casing. A baffle is hinged on the outer casing to cover the top opening of the feeding hopper.

[0008] Preferably, an adjusting plate one and an adjusting plate two are slidably mounted on the outer casing. The adjusting plate one is located above the adjusting plate two. The adjusting plate two has multiple material leakage grooves. An adjusting cylinder is installed on the outer casing. The telescopic shaft of the adjusting cylinder is connected to the top of the adjusting plate one. A straight rod is provided on the adjusting plate one. The straight rod passes through the filter hole and is connected to the adjusting plate two. When the filter plate filters the sandblasting medium, the adjusting cylinder drives the adjusting plate one to rise, which in turn drives the straight rod to move. The up and down movement of the straight rod can prevent the filter hole from being blocked.

[0009] Preferably, both adjusting plate one and adjusting plate two are rotatably mounted with rotating blocks. The two ends of the straight rod are respectively connected to the two rotating blocks. A track rod is installed on the outer shell. The rotating block on adjusting plate one has a through hole one. A ball bearing is provided on the inner wall of the through hole one. A track groove is provided on the track rod. The track groove is spiral-shaped. The track rod passes through the through hole one and is slidably connected to the inner wall of the through hole one. The ball bearing extends into the track groove and contacts the inner wall of the track groove. When adjusting plate one rises, the rotating block moves upward accordingly. Under the action of the track groove and the ball bearing, the rotating block rotates when it moves upward, thereby driving the straight rod to rotate.

[0010] Preferably, a sorting strip is installed on the filter plate. The top of the sorting strip is inclined and the sorting strip is hollow. When the sandblasting medium moves on the filter plate, the sorting strip will slow down the movement of the sandblasting medium. When the sandblasting medium leaves the sorting strip, it will fall a short distance and collide with the filter plate, thereby breaking up the sandblasting medium.

[0011] Preferably, a partition frame is installed on the outer shell, and a T-shaped push plate is installed on the second adjusting plate. The T-shaped push plate extends into the partition frame and slides in connection with the inner wall of the partition frame. An adjusting airbag is installed inside the partition frame, and 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. An air distribution frame is installed on the outer shell, and an air guide hole is opened on the outer shell. The air guide hole is connected to the air distribution frame and the air guide hole is connected to the sorting strip. An air guide pipe is installed on the adjusting airbag, and the air guide pipe is connected to the air distribution frame. An air inlet pipe is installed on the air guide pipe, and a one-way valve is provided on both the air inlet pipe and the air guide pipe. The one-way valve can control the airflow input and output in the adjusting airbag. An air hole is opened on the sorting strip, and a return spring is installed on the partition frame. The return spring is connected to the T-shaped push plate. During the up and down movement of the second adjusting plate, the adjusting airbag will be indirectly driven to contract and expand, thereby providing airflow to the sorting strip. The airflow acts on the sandblasting medium, improving the effect of dispersing the sandblasting medium.

[0012] Preferably, the outer shell has an adjustment slot, and a connecting block is installed on the second adjustment plate. The connecting block passes through the adjustment slot and is slidably connected to the adjustment slot. A gear rack is installed on the outer shell and is connected to the connecting block. A connecting member is rotatably installed on the outer shell, and an annular rack is provided on the connecting member. The annular rack meshes with the gear rack. A limiting roller is rotatably installed on the outer shell. One end of the limiting roller extends outside the outer shell, and a pulley is sleeved on one end of the limiting roller. A transmission belt is sleeved on the pulley and is sleeved on the connecting member. During the up-and-down movement of the second adjustment plate, the gear rack is moved, which in turn drives the connecting member to rotate. Then, the limiting roller is driven to rotate through the transmission belt and pulley, thus avoiding blockage of the sandblasting medium feed.

[0013] Preferably, a weight sensor is provided on the housing to monitor the capacity of the blasting medium, and when the capacity is insufficient, new blasting medium is introduced into the housing.

[0014] Preferably, a rubber sleeve is fitted onto the straight rod, and the rubber sleeve contacts the inner wall of the filter hole, which is used to clean the inner wall of the filter hole during the rotation of the straight rod.

[0015] This invention also proposes a method for cyclic treatment of the sandblasting medium for implant surface treatment, comprising the following steps: S1: The sandblasting medium is sprayed onto the implant through the nozzle to sandblast the surface of the implant. After contacting the implant surface, the sandblasting medium falls into the collection device of the sandblasting machine. S2: Start vacuum feed pump one to discharge the waste sandblasting medium inside the sandblasting machine into the filter plate inside the outer casing through discharge pipe one and feed pipe two; S3: Start the vibration motor to drive the outer shell to vibrate, which indirectly drives the filter plate to vibrate. The sandblasting medium moves on the filter plate and is filtered through the filter holes. S4: Start vacuum feed pump two to transport the filtered sandblasting medium that meets the sandblasting requirements back to the sandblasting machine for reuse through discharge pipe two and feed pipe one, thereby completing the recycling of sandblasting medium. S5: The weight sensor measures the sandblasting medium inside the housing that meets the sandblasting requirements. When the weight of the sandblasting medium is lower than the standard, that is, when the sandblasting medium capacity is lower than the requirement, new sandblasting medium is delivered into the housing through the feeding hopper to ensure the use requirements of the sandblasting machine.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: During use, the sandblasting media treatment device for implant surface treatment can transport the sandblasting media after sandblasting to the outer shell for filtration by setting up vacuum feed pump one and vacuum feed pump two. The media that meets the sandblasting requirements can be transported back to the sandblasting machine for reuse, thereby saving sandblasting costs. By setting an adjusting cylinder to drive adjusting plate one and adjusting plate two to move up and down, and then driving the straight rod to move, the filter holes on the filter plate can be prevented from becoming clogged. Furthermore, by setting rotating blocks at both ends of the straight rod, and making the rotating blocks rotate with adjusting plate one and adjusting plate two, and setting a track rod, the rotating blocks are connected to the track groove on the track rod through ball bearings. As the straight rod moves up and down, it rotates with the rotating blocks, which can clean the inner wall of the filter holes on the filter plate, ensuring the cleanliness of the filter plate and avoiding contamination of the sandblasting medium. By setting a T-shaped push plate, the regulating plate 2 moves up and down, causing the regulating airbag to contract and expand. The airflow generated in this process will act on the sandblasting medium on the filter plate through the sorting strip and the air hole 1 on it. The sandblasting medium is dispersed by the cooperation of the sorting strip, ensuring the filtration effect of the sandblasting medium. By adjusting the up and down movement of the second adjusting plate, the gear rack moves up and down under the action of the connecting block, which in turn drives the connecting parts to rotate. Then, the limiting roller rotates through the transmission belt. The limiting roller can limit the sandblasting medium entering the filter plate, so that the sandblasting medium can be better spread and move, ensuring the filtration effect of the sandblasting medium. Moreover, the rotation setting of the limiting roller can prevent the sandblasting medium from being blocked at the limiting roller, ensuring the normal flow of the sandblasting medium.

[0019] like Figures 1-7As shown, the present invention proposes a sandblasting medium treatment device for implant surface treatment, comprising: a sandblasting machine 1, wherein the sandblasting machine 1 is provided with an inlet pipe 6 and an outlet pipe 7 for inputting sandblasting medium into the sandblasting machine 1 and discharging used sandblasting medium; a medium treatment mechanism is provided on one side of the sandblasting machine 1, the medium treatment mechanism consisting of a housing 2, a vibration motor, and a filter plate 3; the vibration motor is mounted on the housing 2 for driving the housing 2 to vibrate; the filter plate 3 is mounted on the housing 2 for following the vibration of the housing 2; and a support frame is provided below the housing 2, the support frame being connected by a vibration spring. The spring is connected to the outer casing 2. When the vibration motor is working, the outer casing 2 will rotate accordingly, ensuring the filtration effect of the filter plate 3 on the sandblasting media. The filter plate 3 has multiple filter holes for filtering the media. These filter holes are divided into multiple groups according to their inner diameter, with each group having a different inner diameter, to separate sandblasting media of different sizes. The outer casing 2 is equipped with multiple collectors, each located below a corresponding group of filter holes, for collecting sandblasting media of the corresponding size. The outer casing 2 is equipped with a weight sensor, which is positioned within the required range. Below the sandblasting medium collector, a weight sensor, constructed using existing technology, is used to detect the weight of the sandblasting medium within the collector, thereby monitoring the volume of the sandblasting medium in the collector. When the volume of the collector containing the required sandblasting medium is insufficient, new sandblasting medium can be introduced into the collector through the feeding hopper 10 to ensure the normal operation of the sandblasting machine 1. All other collectors used for collecting sandblasting media are equipped with discharge frames for discharging the sandblasting medium. The outer casing 2 is equipped with a vacuum feed pump 4 and a vacuum feed pump 5. The vacuum feed pump 4 is connected to the discharge... The feed pipe 7 is connected to the vacuum feed pump 4, which is equipped with a feed pipe 8 to transport the sandblasting medium used on the sandblasting machine 1 to the outer shell 2. The vacuum feed pump 5 is connected to the feed pipe 6 and is equipped with a discharge pipe 9, which is connected to the outer shell 2. The discharge pipe 9 is used to transport the sandblasting medium that still meets the specifications after screening to the sandblasting machine 1 for continued use in the sandblasting of the implant. The outer shell 2 is equipped with a feeding hopper 10 to add new sandblasting medium into the outer shell 2. A baffle is hinged to the outer shell 2 to cover the top opening of the feeding hopper 10.

[0020] Adjusting plate 11 and adjusting plate 2 are slidably mounted on the outer casing 2. Adjusting plate 11 is located above adjusting plate 2. Adjusting plate 2 has multiple material leakage grooves. Adjusting cylinder 16 is installed on the outer casing 2. The telescopic shaft of adjusting cylinder 16 is connected to the top of adjusting plate 11. A straight rod 13 is provided on adjusting plate 11. The straight rod 13 passes through the filter hole and is connected to adjusting plate 2. When the filter plate 3 filters the sandblasting medium, adjusting plate 11 is driven to rise by adjusting cylinder 16, which in turn drives the straight rod 13 to move. The up and down movement of the straight rod 13 can prevent the filter hole from being blocked.

[0021] Both adjusting plate 11 and adjusting plate 12 are rotatably mounted with rotating blocks 14. The two ends of the straight rod 13 are connected to the two rotating blocks 14 respectively. A track rod 15 is mounted on the outer casing 2. A through hole 14 is provided on the rotating block 14 located on adjusting plate 11. A ball bearing is provided on the inner wall of the through hole 14. A track groove is provided on the track rod 15. The track groove is spiral-shaped and passes through the through hole 14, slidingly connecting with the inner wall of the through hole 14. The ball bearing extends into the track groove and contacts the inner wall of the track groove. When adjusting plate 11 rises, the rotating block 14 rotates... The moving block 14 moves upward accordingly. Under the action of the track groove and the ball, the rotating block 14 rotates as it moves upward, thereby driving the straight rod 13 to rotate. A rubber sleeve is fitted on the straight rod 13, and the rubber sleeve contacts the inner wall of the filter hole. It is used to clean the inner wall of the filter hole during the rotation of the straight rod 13. By setting the rubber sleeve, the straight rod 13 can be prevented from directly contacting the filter hole, thus avoiding damage to the straight rod 13. At the same time, the rubber sleeve can reduce hard compression and reduce wear on the filter hole.

[0022] A sorting bar 22 is installed on the filter plate 3. The top of the sorting bar 22 is inclined and hollow. When the sandblasting medium moves on the filter plate 3, the sorting bar 22 slows down the movement of the sandblasting medium. When the sandblasting medium detaches from the sorting bar 22, it will fall a short distance and collide with the filter plate 3, thereby breaking up the sandblasting medium. A partition frame 17 is installed on the outer shell 2. A T-shaped push plate 18 is installed on the adjusting plate 22. The T-shaped push plate 18 extends into the partition frame 17 and slides in connection with the inner wall of the partition frame 17. An adjusting airbag 19 is installed inside the partition frame 17. The outer side 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. An air distribution frame 20 is installed on the outer shell 2. An air guide hole is opened on the outer shell 2. The air guide hole communicates with the air distribution frame 20 and the sorting bar 22. An air guide pipe 21 is installed on the 19, which is connected to the air distribution frame 20. An air inlet pipe is installed on the air guide pipe 21. Both the air inlet pipe and the air guide pipe 21 are equipped with one-way valves. The one-way valve on the air inlet pipe can only input airflow into the regulating airbag 19, and the one-way valve on the air guide pipe 21 can only input airflow into the air distribution frame 20. The one-way valves can control the input and output of airflow in the regulating airbag 19. An air hole 1 is opened on the sorting bar 22. The air hole 1 is set at an upward angle so that the airflow blows the sandblasting medium upward as it is discharged through the air hole 1. A return spring is installed 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, it will indirectly drive the regulating airbag 19 to contract and expand, thereby providing airflow into the sorting bar 22. The airflow acts on the sandblasting medium, improving the effect of dispersing the sandblasting medium.

[0023] An adjustment slot is provided on the outer casing 2. A connecting block is installed on the adjustment plate 12. The connecting block passes through the adjustment slot and is slidably connected to the adjustment slot. A gear rack 23 is installed on the outer casing 2 and is connected to the connecting block. A connecting member 24 is rotatably installed on the outer casing 2. The connecting member 24 is provided with an annular rack, which meshes with the gear rack 23. A limiting roller 25 is rotatably installed on the outer casing 2. One end of the limiting roller 25 extends outside the outer casing 2, and a pulley is sleeved on one end of the limiting roller 25. A transmission belt 26 is sleeved on the pulley and is sleeved on the connecting member 24. During the up-and-down movement of the second 12, the gear rack 23 moves, which in turn drives the connecting piece 24 to rotate. Then, through the transmission belt 26 and pulley, the limiting roller 25 rotates, preventing blockage of the sandblasting medium feed. A baffle plate 27 is installed on the outer shell 2. The baffle plate 27 is located above the limiting roller 25 and contacts the outer side of the limiting roller 25. The baffle plate 27 can clean the outer wall of the limiting roller 25 during the reverse rotation process, ensuring the cleanliness of the outer wall of the limiting roller 25 and preventing the sandblasting medium from adhering to the outer wall of the limiting roller 25, which would affect 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. After the sandblasting is completed, the sandblasting medium is transported to the outer shell 2 through the vacuum feed pump 4, the discharge pipe 7 and the feed pipe 8. The sandblasting medium is filtered by the filter plate 3. The filtered sandblasting medium falls into the collection container below. Among them, the sandblasting medium that meets the sandblasting requirements is transported back to the sandblasting machine 1 through the vacuum feed pump 5, the discharge pipe 9 and the feed pipe 6 for sandblasting again. This can save the cost of sandblasting medium. The volume of sandblasting medium in the collection container can be monitored by the weight sensor. When the volume is low, new sandblasting medium can be input into the collection container through the feeding hopper 10, thereby ensuring the sandblasting needs of the sandblasting machine 1. During the sandblasting media filtration process, the regulating cylinder 16 can be activated to move the regulating plate 11 up and down, which in turn can indirectly move the straight rod 13 and the regulating plate 12 up and down. During the up and down movement of the straight rod 13, the sandblasting media can be prevented from getting stuck in the filter holes on the filter plate 3, causing blockage and ensuring the filtration effect of the filter plate 3 on the sandblasting media. At the same time, under the action of the track rod 15, during the upward movement of the regulating plate 11, the rotating block 14 can be driven to rotate through the track groove and ball bearings, thereby driving the straight rod 13 to rotate, so that the straight rod 13 is in the rotating state inside the filter hole. Under the action of the rubber sleeve, the inner wall of the filter hole can be cleaned, thus ensuring the cleanliness of the filter plate 3 and preventing the sandblasting media from remaining on the filter plate 3 and causing pollution. During the up-and-down movement of the adjusting plate 12, the T-shaped push plate 18 will move, which will cause the adjusting air bag 19 to expand or contract. When contracting, the air will flow through the air guide pipe 21 and the air distribution frame 20 into the sorting strip 22, and then act on the sandblasting medium on the filter plate 3 through multiple air holes. Under the combined action of the sorting strip 22, the sandblasting medium moving on the filter plate 3 will be dispersed to ensure the filtration effect of the sandblasting medium. Meanwhile, as the adjusting plate 12 moves up and down, the connecting block drives the gear rack 23 to move, and the connecting piece 24 and the transmission belt 26 drive the limiting roller 25 to rotate, thereby preventing the sandblasting medium from getting blocked at the limiting roller 25. The limiting roller 25 can limit the amount of sandblasting medium, so that it is in a uniform and flat state before flowing to the filter plate 3, ensuring the subsequent filtration effect.

[0025] This invention proposes a method for cyclic treatment of implant surface with sandblasting media, comprising the following steps: S1: The sandblasting medium is sprayed onto the implant through the nozzle to sandblast the surface of the implant. After contacting the surface of the implant, the sandblasting medium falls into the collection device of the sandblasting machine 1. S2: Start the vacuum feed pump 4 to discharge the waste sandblasting medium in the sandblasting machine 1 into the filter plate 3 inside the outer casing 2 through the discharge pipe 7 and the feed pipe 8. S3: Start the vibration motor to drive the outer shell 2 to vibrate, which indirectly drives the filter plate 3 to vibrate. The sandblasting medium moves on the filter plate 3 and is filtered through the filter holes. S4: Start the vacuum feed pump 25 to transport the filtered sandblasting medium that meets the sandblasting requirements back to the sandblasting machine 1 through the discharge pipe 29 and the feed pipe 16 for reuse, thereby completing the recycling of the sandblasting medium. S5: The weight sensor is used to measure the sandblasting medium inside the housing 2 that meets the sandblasting requirements. When the weight of the sandblasting medium is lower than the standard, that is, when the sandblasting medium capacity is lower than the requirement, new sandblasting medium is delivered into the housing 2 through the feeding hopper 10 to ensure the use requirements of the sandblasting machine 1.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.

The ball extends into the track groove and contacts the inner wall of the track groove. When adjusting plate one (11) rises, the rotating block (14) moves upward accordingly. Under the action of the track groove and the ball, the rotating block (14) rotates when it moves upward, thereby driving the straight rod (13) to rotate.

4. The sandblasting media treatment device for implant surface treatment according to claim 1, characterized in that, An adjustment slot is provided on the outer shell (2). A connecting block is installed on the adjustment plate (12). The connecting block passes through the adjustment slot and is slidably connected to the adjustment slot. A gear rack (23) is installed on the outer shell (2). The gear rack (23) is connected to the connecting block. A connecting piece (24) is rotatably installed on the outer shell (2). A ring rack is provided on the connecting piece (24). The ring rack meshes with the gear rack (23). A limiting roller (25) is rotatably installed on the outer shell (2). One end of the limiting roller (25) extends to the outside of the outer shell (2). A pulley is sleeved on one end of the limiting roller (25). A transmission belt (26) is sleeved on the pulley. The transmission belt (26) is sleeved on the connecting piece (24). During the up-and-down movement of the adjustment plate (12), the gear rack (23) is moved, which in turn drives the connecting piece (24) to rotate. Then, the limiting roller (25) is rotated through the transmission belt (26) and the pulley, thus avoiding blockage of the sandblasting medium feed.

5. The sandblasting media treatment device for implant surface treatment according to claim 1, characterized in that, A weight sensor is installed on the outer casing (2) to monitor the capacity of the blasting medium. When the capacity is insufficient, new blasting medium is input into the outer casing (2).

6. The sandblasting media treatment device for implant surface treatment according to claim 3, characterized in that, A rubber sleeve is fitted on the straight rod (13), and the rubber sleeve contacts the inner wall of the filter hole, which is used to clean the inner wall of the filter hole during the rotation of the straight rod (13).

7. The method for cyclic treatment of a sandblasting medium for implant surface treatment according to claim 1, comprising the following steps: S1: The sandblasting medium is sprayed onto the implant through the nozzle to sandblast the surface of the implant. After contacting the surface of the implant, the sandblasting medium falls into the collection device of the sandblasting machine (1). S2: Start vacuum feed pump one (4) to discharge the waste sandblasting medium in the sandblasting machine (1) into the filter plate (3) inside the outer shell (2) through discharge pipe one (7) and feed pipe two (8); S3: Start the vibration motor to drive the outer shell (2) to vibrate, which indirectly drives the filter plate (3) to vibrate. The sandblasting medium moves on the filter plate (3) and is filtered through the filter holes. S4: Start the vacuum feed pump 2 (5) to transport the filtered sandblasting medium that meets the sandblasting requirements back to the sandblasting machine (1) through the discharge pipe 2 (9) and the feed pipe 1 (6) for reuse, thereby completing the recycling of the sandblasting medium; S5: Use a weight sensor to measure the sandblasting medium inside the shell (2) that meets the sandblasting requirements. When the weight of the sandblasting medium is lower than the standard, that is, the sandblasting medium capacity is lower than the requirement, new sandblasting medium is delivered into the shell (2) through the feeding hopper (10) to ensure the use requirements of the sandblasting machine (1).
