Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, specifically a brushless polishing device for dental prosthesis processing. Background Technology

[0002] Dentures are false teeth used to repair various defects, prevent and treat diseases of the oral and maxillofacial system, and restore the normal shape and physiological function of the oral and maxillofacial system after teeth have been lost or extracted.

[0003] In the production and processing of existing dentures, it is necessary to polish the dentures, which requires the use of corresponding polishing devices. Polishing devices that use brushless motors as power sources are called brushless polishing devices. Compared with traditional brushed motors, they have advantages such as long life, high efficiency, low maintenance cost, low noise, and high speed. Existing patent CN202421525768.6 discloses a brushless polishing device for denture processing, including an operating table and a polishing machine. The operating table has a hollow internal structure, and its top surface has a storage slot and a fixing slot. The side of the fixing slot has several through holes communicating with the inside of the operating table. A filter plate is installed inside the operating table between the storage slot and the fixing slot. The rear end face of the operating table has an opening, and the side has a discharge port. A fan is installed inside the operating table at the opening, and a sealing plate is installed at the discharge port. The polishing machine includes a housing, and a brushless motor is installed inside the housing. The output shaft of the brushless motor is detachably connected to a polishing head through a positioning pin. In the actual implementation of the aforementioned patent, although a dust-collecting fan is included, the grinding block rotates at a high speed during the grinding process. Grinding debris is then ejected outwards by centrifugal force, forming dust particles that can travel long distances and easily pollute the surrounding environment, resulting in poor dust removal. Therefore, we propose a brushless grinding device for denture processing. Utility Model Content

[0004] The purpose of this invention is to provide a brushless polishing device for denture processing, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a brushless polishing device for denture processing, including a platform, a cover on the top of the platform, the top of the cover being a transparent plate, a lifting assembly installed on the rear side of the platform, the lifting assembly being used to drive the cover to rise and fall, and a placement box fixedly connected to one side wall of the platform via a bracket, the placement box containing a polishing assembly. Both sides of the cover have through holes. A baffle is fixedly installed on one side of the top of the platform. A suction nozzle is embedded in the top of the platform near the baffle. A dust collection assembly is installed on the other side of the platform. The dust collection assembly is used to make the suction nozzle suck up dust under negative pressure.

[0006] By adopting the above technical solution, the drive component first lifts the cover, then the denture is held in one hand and the grinding component in the other, and placed on the platform. The cover is then lowered so that the hand is placed inside the through hole. The denture is then ground inside the cover. During the grinding process, the grinding process can be observed through the transparent plate on the top of the cover. During grinding, the grinding debris generated by the grinding component flies towards the baffle. First, the cover can prevent the debris from flying elsewhere and causing pollution to the surrounding environment. Then, the baffle blocks the debris, causing it to fall to the suction nozzle. The dust collection component then allows the suction nozzle to remove the debris, thereby achieving dust removal.

[0007] In a preferred embodiment of the present invention, the grinding assembly includes a housing, one end of which is fixedly connected to a brushless motor, and the outer end of the brushless motor is detachably fixedly connected to a grinding block.

[0008] By adopting the above technical solution, the brushless motor drives the grinding block to rotate, thereby using the grinding block to grind the denture. Specifically, a battery is also installed inside the housing to power the brushless motor.

[0009] In a preferred embodiment of this utility model, the lifting assembly includes a vertical plate, which is fixed to the rear side wall of the platform. A sliding cavity is formed on one side wall of the vertical plate. A lead screw motor is fixedly installed at the bottom of the inner cavity of the sliding cavity. A lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor. The outer end of the lead screw is rotatably connected to the top of the inner cavity of the sliding cavity. A suitable lead screw slider is fitted on the outer wall of the lead screw. The outer wall of the lead screw slider is fixedly connected to the cover through a connecting block.

[0010] By adopting the above technical solution, the lead screw is driven to rotate by the lead screw motor, thereby driving the lead screw slider to rise and fall, thus realizing the lifting and lowering of the cover.

[0011] In a preferred embodiment of the present invention, a scraper is fixedly connected to the inner wall of the cover, the scraper is attached to one side wall of the baffle, and the outer wall of the scraper is provided with an inclined surface.

[0012] By adopting the above technical solution, the lifting component can scrape the surface of the baffle by the scraper during the lifting process of the cover, thereby scraping off the debris adhering to the baffle. This allows the adhered debris to be cleaned off and sucked away, thus improving the cleaning effect. The outer wall of the scraper has a bevel, so the debris scraped off during the lifting can slide outward along the bevel, allowing the debris to fall accurately to the suction nozzle, which helps to improve the effect of debris suction.

[0013] In a preferred embodiment of the present invention, the dust collection assembly includes an exhaust fan and a filter box. The exhaust fan and the filter box are fixedly installed on one side wall of the platform. One end of the exhaust fan is connected to one side of the filter box. A filter screen is fixedly installed in the inner cavity of the filter box. A dust collection pipe is fixedly connected to the other side wall of the filter box. The other end of the dust collection pipe passes through the platform and is fixedly connected to the suction nozzle.

[0014] By adopting the above technical solution, the exhaust fan can create negative pressure in the filter box, which in turn creates negative pressure in the suction nozzle, thereby drawing out the debris and allowing it to enter the filter box where it is filtered out by the filter screen, thus achieving the collection of debris generated during grinding.

[0015] In a preferred embodiment of this utility model, suitable rubber pads are fixedly glued to the four corners of the bottom of the platform.

[0016] By adopting the above technical solution and setting the rubber pad, the overall stability of the device during use is greatly improved.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: The present application provides a brushless polishing device for denture processing. By lowering the cover, the polishing area can be shielded, which helps to prevent flying debris from flying to other places and causing pollution to the surrounding environment. Moreover, the baffle can block the flying debris, so that the flying debris can automatically fall off after hitting the baffle and be extracted by the dust collection component, thereby improving the dust removal effect. During the process of lifting the cover, the lifting component can use a scraper to scrape the surface of the baffle, thereby scraping off the debris adhering to the baffle. This allows the adhered debris to be cleaned off and then sucked away, thus improving the cleaning effect. The scraper has an inclined surface on its outer wall, which allows the debris scraped off during lifting to slide outward along the inclined surface, ensuring that the debris falls accurately to the suction nozzle, thus improving the debris removal effect.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a brushless polishing device for denture processing, including a platform 1, a cover 2 on the top of the platform 1, the top of the cover 2 being a transparent plate, a lifting component installed on the rear side of the platform 1, the lifting component being used to drive the cover 2 to rise and fall, and a placement box 13 fixedly connected to one side wall of the platform 1 via a bracket 12, and a polishing component being disposed inside the placement box 13. Both sides of the cover 2 have through holes 21. A baffle 11 is fixedly installed on one side of the top of the platform 1. A suction nozzle 3 is embedded on the top of the platform 1 near the baffle 11. A dust collection assembly is installed on the other side of the platform 1. The dust collection assembly is used to make the suction nozzle 3 suction dust under negative pressure.

[0021] It should be understood that in actual use, the drive assembly first lifts the cover 2, then the denture is held in one hand and the polishing assembly in the other, and placed on the stage 1. The cover 2 is then lowered so that the hand is placed inside the through hole 21. The denture is polished inside the cover 2. During the polishing process, the polishing can be observed through the transparent plate on the top of the cover 2. During polishing, the polishing debris generated by the polishing assembly flies towards the baffle 11. First, the cover 2 can prevent the debris from flying to other places and causing pollution to the surrounding environment. Then, the baffle 11 blocks the debris, causing it to fall to the suction nozzle 3. Then, the dust collection assembly allows the suction nozzle 3 to suck up the debris, thereby achieving dust removal.

[0022] Furthermore, suitable rubber pads are fixedly glued to the four corners of the bottom of the platform 1. The setting of the rubber pads makes the overall stability of the device highly stable when placed and used.

[0023] like Figure 1 and 2 As shown; the grinding assembly includes a housing 14, one end of which is fixedly connected to a brushless motor 15, and the outer end of the brushless motor 15 is detachably fixedly connected to a grinding block 16. It should be understood that the brushless motor 15 drives the grinding block 16 to rotate, thereby using the grinding block 16 to grind the denture. Specifically, a battery is also installed inside the housing 14 to power the brushless motor 15.

[0024] like Figure 1 and 3 As shown in Figure 4, the lifting assembly includes a vertical plate 22, which is fixed to the rear side wall of the platform 1. A sliding cavity is provided on one side wall of the vertical plate 22. A lead screw motor 23 is fixedly installed at the bottom of the inner cavity of the sliding cavity. A lead screw 24 is fixedly connected to the outer end of the drive shaft of the lead screw motor 23. The outer end of the lead screw 24 is rotatably connected to the top of the inner cavity of the sliding cavity. A suitable lead screw slider 25 is fitted on the outer wall of the lead screw 24. The outer wall of the lead screw slider 25 is fixedly connected to the cover 2 through a connecting block.

[0025] It should be understood that the lead screw 24 is rotated by the lead screw motor 23, which in turn drives the lead screw slider 25 to rise and fall, thereby driving the cover 2 to rise and fall.

[0026] Furthermore, a scraper 26 is fixedly connected to the inner wall of the cover 2. The scraper 26 is attached to one side wall of the baffle 11, and the outer wall of the scraper 26 is provided with an inclined surface. It should be understood that during the lifting process of the lifting assembly, the scraper 26 can scrape the surface of the baffle 11, thereby removing the debris adhering to the baffle 11. This allows the adhered debris to be cleaned off and sucked away, thus improving the cleaning effect. The outer wall of the scraper 26 has a slope, so the debris scraped off during the lifting process can slide outward along the slope, allowing the debris to fall accurately to the suction nozzle 3, which helps to improve the effect of debris suction.

[0027] like Figure 1 and 2 As shown; the dust collection assembly includes an exhaust fan 31 and a filter box 32. The exhaust fan 31 and the filter box 32 are fixedly installed on one side wall of the platform 1. One end of the exhaust fan 31 is connected to one side of the filter box 32. A filter screen plate 34 is fixedly installed in the inner cavity of the filter box 32. A dust collection pipe 33 is fixedly connected to the other side wall of the filter box 32. The other end of the dust collection pipe 33 passes through the platform 1 and is fixedly connected to the suction nozzle 3.

[0028] It should be understood that in actual use, the exhaust fan 31 can create a negative pressure in the filter box 32, which in turn creates a negative pressure in the suction nozzle 3, thereby drawing out the debris and allowing it to enter the filter box 32 and be filtered out by the filter screen 34, thus achieving the collection of debris generated during grinding.
