Abstract
Description
Technical Field
[0001] This utility model relates to the field of dental prosthesis processing technology, specifically a dental prosthesis steel frame grinding device. Background Technology
[0002] Dental metal bases are the core components of partial dentures, serving to support and reinforce the denture base. They are generally made of cast metal, which is strong and not easily broken. It also allows the base to be made thinner and smaller, making it comfortable and aesthetically pleasing for patients, and also plays a role in temperature conduction.
[0003] During the production process, dental prostheses often require manual polishing to ensure a proper fit for the user. Most existing dental prosthesis polishing devices are open-type equipment, and the fine dust generated during polishing can float in the air and pollute the environment. Furthermore, during the polishing process, the user may need to move the prosthesis close to their eyes for detailed observation, and the dust generated during polishing can easily float into the eyes and cause harm to the operator. Utility Model Content

[0006] Preferably, an opening and closing door is hinged to one side of the machine body shell, and an access port is provided through one side of the opening and closing door and the other side of the machine body shell. The opening and closing door can open the machine body shell so that the user can put his arm into the machine body shell to perform equipment maintenance. When grinding the steel support, the user can directly put his arm into the machine body shell through the access port to perform the grinding operation. A flexible curtain is provided at the access port to prevent dusty air from blowing out of the machine body shell.
[0007] Preferably, one side of the magnifying glass is connected to two first electric push rods along with the inner wall of the glass cavity. The two electric push rods support the magnifying glass inside the glass cavity. During polishing, the user can observe the steel support inside the outer shell through the observation window. If it is necessary to observe details, the two electric push rods can be used to drive the magnifying glass to be positioned below the observation window to magnify the image inside the outer shell, which is convenient for detailed polishing. The glass cavity protects the magnifying glass and prevents dust from sticking to the surface of the magnifying glass and affecting the observation effect.
[0008] Preferably, the inside of the collection box is provided with two scrapers through a slot, and each of the top edges of the two scrapers is provided with a second electric push rod. The two second electric push rods are respectively connected to the two sides of the inner wall of the collection box. The two scrapers can be driven by the corresponding second electric push rods to perform linear movement inside the collection box, scraping the sewage falling inside the collection box.
[0009] Preferably, a filter screen is provided at the middle position of the bottom of the collection box. When the two scrapers move relatively linearly inside the collection box and scrape the sewage to the position of the filter screen, the sewage is filtered by the filter screen, allowing the water to pass through the filter screen, while the dust carried in the sewage is blocked by the filter screen and left inside the collection box.
[0010] Preferably, one end of the dust scraper arm extends out of the outer casing of the machine body. When the extended end of the dust scraper arm is pushed outside the outer casing of the machine body, it will cause the dust scraper arm located at the bottom of the glass cavity to move at the bottom of the glass cavity, scraping away the dust stuck to the bottom of the glass cavity, ensuring that the user can observe the inside of the outer casing of the machine body through the observation window and the glass cavity.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This denture frame polishing device uses a sprayer and a fan installed opposite each other on the inner wall of the machine body. The fan blows the dust generated during polishing to the area below the sprayer, where it is sprayed and absorbed. Wastewater falls into a collection box below the sprayer. The liquid filtered through the collection box is then transported back to the sprayer through a water tank and a delivery pipe for continuous spraying. This allows the denture frame polishing device to collect and centrally process the dust, preventing dust from floating in the air and causing environmental pollution during polishing.
[0013] 2. This denture frame polishing device uses a magnifying glass inside the glass cavity and an observation window on the top of the machine body to work together. When polishing the denture frame, the observation window is used to observe the inside of the machine body, and the magnifying glass is movable to facilitate observation of the detailed polishing status of the frame.

[0021] like Figures 1 to 4As shown, the dental prosthesis metal frame grinding device in this embodiment includes a machine body shell 1. An operating platform 6 is located at the bottom of the inner part of the machine body shell 1, and a grinding component 7 is located on the top of the operating platform 6. The machine body shell 1 protects the top of the operating platform 6. When grinding is performed on the upper part of the operating platform 6 by the grinding component 7, the machine body shell 1 traps the dust generated during grinding inside the machine body shell 1, preventing dust from floating in the operating room with the air. A recessed groove 8 is provided at the rear end of the operating platform 6, and a sprayer 9 is installed on the inner wall of the machine body shell 1 above the recessed groove 8. A device is placed inside the recessed groove 8. There is a collection box 10, with a connecting pipe 18 at the bottom center of the collection box 10. A water collection tank 17 is located at the bottom of the connecting pipe 18. One side of the water collection tank 17 and the other side of the sprayer 9 are connected to an infusion pipe 2. A fan 20 is located at the front end of the outer casing 1, with one end of the fan 20 extending into the interior of the outer casing 1. During the grinding of the steel support, fine dust is generated. The fan 20 blows air towards the sprayer 9 from inside the outer casing 1, causing airflow inside the outer casing 1. This airflow carries the fine dust downwards towards the sprayer 9, which then sprays liquid downwards. Dust in the air is adsorbed and falls into the collection box 10 for collection, preventing dust from floating inside the outer shell 1 and obstructing vision. The wastewater containing the adsorbed dust is filtered inside the collection box 10, leaving the dust inside. The filtered liquid flows through the pipe 18 into the water tank 17, which contains a water pump. The water tank 17 then delivers the liquid through the infusion pipe 2 to the sprayer 9 for further dust suppression. An observation window 5 is provided at the top of the outer shell 1, and a glass cavity 11 is provided at the upper part of the inner side of the outer shell 1. The unit is equipped with a magnifying glass 13, and a dust scraper arm 12 is provided at the bottom of the glass cavity 11. The dust scraper arm 12 is hinged and installed inside the outer shell 1 of the machine body. When the steel support is being polished, the user can observe the polishing status in real time through the observation window 5. If it is necessary to observe the details carefully, the magnifying glass 13 can be moved to the bottom of the observation window 5 to magnify the image inside the outer shell 1 of the machine body for easy observation. During the polishing process, dust may stick to the bottom of the glass cavity 11. If the dust affects the observation line of sight, the dust scraper arm 12 can be used to scrape the bottom of the glass cavity 11 to remove the dust.
[0022] Specifically, an opening door 3 is hinged to one side of the outer casing 1. An access port 4 is provided through one side of the opening door 3 and the other side of the outer casing 1. The opening door 3 can open the outer casing 1 so that the user can put their arm into the outer casing 1 to perform equipment maintenance. When grinding the steel support, the user can directly put their arm into the outer casing 1 through the access port 4 to perform the grinding operation. A flexible curtain is provided at the access port 4 to prevent dusty air from blowing out of the outer casing 1.
[0023] Furthermore, one side of the magnifying glass 13 is connected to two first electric push rods 14, which together with the inner wall of the glass cavity 11. The two electric push rods support the magnifying glass 13 inside the glass cavity 11. During polishing, the user can observe the state of the steel support inside the outer shell 1 through the observation window 5. If it is necessary to observe details, the two electric push rods can be used to drive the magnifying glass 13 to be located below the observation window 5 to magnify the image inside the outer shell 1, which is convenient for fine polishing. The glass cavity 11 protects the magnifying glass 13 and prevents dust from sticking to the surface of the magnifying glass 13 and affecting the observation effect.
[0024] Furthermore, the inside of the collection box 10 is provided with two scrapers 16 through the slot. Each of the top sides of the two scrapers 16 is provided with a second electric push rod 15. The two second electric push rods 15 are respectively connected to the two sides of the inner wall of the collection box. The two scrapers 16 can be driven by the corresponding second electric push rods 15 to perform linear movement inside the collection box and scrape the sewage falling inside the collection box.
[0025] Furthermore, a filter screen 19 is provided at the bottom center of the collection box. When the two scrapers 16 move relatively linearly inside the collection box and scrape the sewage to the position of the filter screen 19, the sewage is filtered by the filter screen 19, allowing the water to pass through the filter screen 19, while the dust carried in the sewage is blocked by the filter screen 19 and left inside the collection box.
[0026] Furthermore, one end of the dust scraper arm 12 extends out of the outer casing 1. When the extended end of the dust scraper arm 12 is pushed outside the outer casing 1, it will cause the dust scraper arm 12 located at the bottom of the glass cavity 11 to move at the bottom of the glass cavity 11, scraping away the dust stuck to the bottom of the glass cavity 11, ensuring that the user can observe the inside of the outer casing 1 through the observation window 5 and the glass cavity 11.
[0027] The usage method of this embodiment is as follows: When using the denture frame polishing device, the user can directly insert their arm and denture frame into the machine housing 1 through the insertion port 4 to perform the polishing operation. During polishing, fine dust is generated. The fan 20 blows air towards the sprayer 9 inside the machine housing 1, causing airflow inside the machine housing 1. This airflow carries the fine dust downwards towards the sprayer 9, which sprays liquid downwards, adsorbing the dust in the air and causing it to fall into the collection box 10 for collection. This prevents dust from floating inside the machine housing 1 and obstructing vision. The wastewater that adsorbs the dust is then collected in the collection box 10. The filter traps dust inside the collection box 10. The filtered liquid flows into the water collection tank 17 through the pipe 18. The water collection tank 17 contains a water pump that delivers the liquid through the infusion pipe 2 to the sprayer 9 for spraying and dust suppression. The user can observe the polishing process in real time through the observation window 5. If a closer look is needed, the magnifying glass 13 can be moved to the bottom of the observation window 5 to magnify the image inside the casing 1 for easier observation. During the polishing process, dust may stick to the bottom of the glass cavity 11. If the dust obstructs the view, the dust scraper arm 12 can be used to scrape the bottom of the glass cavity 11 to remove the dust.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
