Description

Technical Field

[0001] This utility model relates to the field of dental dry grinding technology, and in particular to a dust-free dry grinding machine for producing removable dentures. Background Technology

[0002] In dental prosthetics, denture fabrication involves processes such as grinding and polishing to achieve a smooth surface and a good fit. Traditional grinding processes, using handheld or pedestal-mounted grinding equipment, generate a large amount of dust during operation. This dust contains particles of titanium alloys, nickel-chromium alloys, ceramics, and resins. These dust particles are characterized by their small size and high suspension capacity, making them easily inhaled and potentially leading to occupational diseases such as pneumoconiosis with prolonged exposure.

[0003] Existing technology, such as CN217966349U, discloses a dust-free dry grinding machine for producing removable dentures, including a shell, a grinding mechanism, a clamping mechanism, a sliding mechanism, and a dust collection mechanism. The clamping mechanism is located below the grinding mechanism, and sliding mechanisms are located on both sides of the clamping mechanism and above the grinding mechanism. The dust collection mechanism is located below the clamping mechanism. The advantages are that the clamping rod, cylinder, synchronous motor, and Z-axis slide rail enable the rotation and Z-axis movement of the removable denture during the grinding process, and the grinding head and rotary motor enable all-around grinding of the removable denture.

[0004] The method involves using a closed structure to polish the denture to prevent dust from spreading. It uses a denture with a built-in polishing head for polishing. However, the shape of the denture is non-standard, and the polishing head cannot achieve uniform and sufficient polishing, resulting in poor polishing effect. Utility Model Content

[0005] Given that the existing dentures are non-standard in shape, the grinding head cannot achieve uniform and sufficient grinding when grinding the dentures, so this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a dust-free dry grinding machine for producing removable dentures, which aims to control the spread of dust while manually grinding dentures.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a dust-free dry grinding machine for producing removable dentures, including a chassis, a vertical frame welded to the rear side of the top of the chassis, an L-shaped dust baffle fixed to the front face of the vertical frame on the side away from the chassis, an observation window opened on the front side of the dust baffle, a glass plate fixed inside the observation window, a servo motor mounted on one side of the top of the chassis via a pad, and a grinding disc mounted on the drive end of the servo motor;

[0008] Dust suction pipes are installed on both sides of the inner wall of the dust baffle, and multiple dust suction holes are opened on the end face of the dust suction pipe away from the dust baffle. A dust suction assembly is installed on the top of the chassis and in front of the vertical frame, and the dust inlet end of the dust suction assembly is connected to the dust removal end of the dust suction pipe.

[0009] A cleaning strip is slidably installed between the two suction pipes, and a plurality of rubber scrapers for cleaning the glass plate are fixed to one end of the cleaning strip near the glass plate.

[0010] As an improved technical solution, the dust collection assembly includes a vacuum cleaner mounted on the top of the chassis. The suction end of the vacuum cleaner is fixedly connected to a dust inlet pipe. A T-shaped pipe is fixedly connected to the end of the dust inlet pipe away from the vacuum cleaner, and the two dust inlet ends of the T-shaped pipe are respectively connected to the dust outlet ends of the two suction pipes.

[0011] As an improved technical solution, a protruding plate is integrally formed on the top of the chassis and on the side of the vertical frame away from the dust collection component. The dust collection component also includes a mesh filter cartridge disposed on the protruding plate, and a dust outlet pipe is fixedly connected to the dust outlet end of the vacuum cleaner.

[0012] As an improved technical solution, an electromagnet is installed on the top of the chassis and directly below the cleaning strip, and a magnetic strip is embedded in the bottom of the cleaning strip, with the magnetic strip and the electromagnet in a magnetically repulsive state.

[0013] As an improved technical solution, hollow slides are fixed to the opposite sides of the two suction pipes, and universal ball bearings that limit rolling inside the hollow slides are installed on both sides of the cleaning strip.

[0014] As an improved technical solution, a stop bar is fixed between the opposing surfaces of the two hollow slide blocks and at the end away from the cleaning strip, and springs are fixed on both sides of the stop bar near the end face of the cleaning strip.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the denture is held by hand. Both hands enter the inner cavity of the dustproof plate from both sides. At this time, the denture is held by both hands and the denture is manipulated to contact the high-speed rotating grinding disc to achieve the grinding of the denture. The operator can directly see the contact surface and contact effect between the denture and the grinding disc through the glass plate, which makes it easier to control the contact between the denture and the grinding disc more accurately.

[0017] 2. In this invention, when polishing dentures, the denture is manually held and brought into contact with the polishing disc for polishing. This allows for easy control of the contact angle between the denture and the polishing disc, resulting in excellent polishing effects. Furthermore, a dust baffle blocks dust and controls its movement, preventing it from spreading towards the worker's location. Simultaneously, the vacuum cleaner generates negative pressure, forcing dust into the vacuum pipe through the suction holes. Finally, the dust passes through a three-way pipe, dust inlet pipe, and dust outlet pipe into the mesh filter cartridge. The dust is collected as soon as it is stirred up, facilitating dust-free polishing and protecting both the environment and workers.

[0018] 3. This utility model utilizes an electromagnet to generate magnetism that repels the magnetic strip at the bottom of the cleaning strip. Under the influence of this magnetic repulsion, the cleaning strip moves away from the electromagnet and along the hollow slide. During this movement, the rubber scraper contacts the inner wall of the glass plate, cleaning it and improving the clarity of observation for workers. Furthermore, the magnetic repulsion drives the cleaning strip's movement, eliminating the need for manual wiping and reducing the workload. Simultaneously, when the cleaning strip collides with the spring, the spring's elasticity causes the cleaning strip to rebound and return to its original position, eliminating the need for manual resetting and enabling more convenient reciprocating movement.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a dust-free dry grinding machine for producing removable dentures. This dust-free dry grinding machine for producing removable dentures includes a chassis 1. A vertical frame 2 is welded to the rear side of the top of the chassis 1. An L-shaped dust baffle 6 is fixed to the front face of the vertical frame 2 on the side away from the chassis 1. The dust baffle 6 blocks dust and controls the direction of dust movement to prevent dust from spreading towards the worker. An observation window 61 is opened on the front side of the dust baffle 6. A glass plate 7 is fixed inside the observation window 61. The worker can directly see the contact surface and contact effect between the denture and the grinding disc 4 through the glass plate 7, which facilitates more accurate control of the contact between the denture and the grinding disc 4. A servo motor 5 is installed on one side of the top of the chassis 1 through a pad 9. The grinding disc 4 is installed on the drive end of the servo motor 5. When grinding the denture, the denture is manually held and contacted with the grinding disc 4 for grinding, which facilitates control of the denture and the grinding disc 4 to contact at any angle, resulting in a good grinding effect.

[0028] Dust suction pipes 10 are installed on both sides of the inner wall of the dust baffle 6, and multiple dust suction holes are opened on the end face of the dust suction pipe 10 away from the dust baffle 6. A dust suction assembly 3 is installed on the top of the chassis 1 and in front of the vertical frame 2, and the dust inlet end of the dust suction assembly 3 is connected to the dust removal end of the dust suction pipe 10.

[0029] The vacuuming assembly 3 includes a vacuum cleaner 31 mounted on the top of the chassis 1. The vacuum cleaner 31 has a vacuum inlet pipe 34 fixedly connected to its suction end. A three-way pipe 35 is fixedly connected to the end of the vacuum inlet pipe 34 away from the vacuum cleaner 31. The two suction ends of the three-way pipe 35 are respectively connected to the discharge ends of the two vacuum pipes 10.

[0030] The top of the chassis 1 and the side of the vertical frame 2 away from the dust collection component 3 are integrally formed with a protruding plate. The dust collection component 3 also includes a mesh filter cartridge 33 disposed on the protruding plate. The dust outlet end of the vacuum cleaner 31 is fixedly connected to a dust outlet pipe 32. The dust outlet end of the dust outlet pipe 32 passes through the vertical frame 2 and is connected to the dust inlet end of the mesh filter cartridge 33.

[0031] During use, the vacuum cleaner 31 generates negative pressure, causing dust to enter the interior of the suction pipe 10 through the suction holes on the suction pipe 10. Finally, the dust enters the interior of the mesh filter cartridge 33 through the three-way pipe 35, the dust inlet pipe 34, and the dust outlet pipe 32. The dust can be collected as soon as it is raised, which is conducive to achieving dust-free polishing and has a protective effect on the environment and workers.

[0032] Example 2

[0033] Reference Figures 1-3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a cleaning strip 15 is slidably installed between the two suction pipes 10, and a plurality of rubber scrapers 16 for cleaning the glass plate 7 are fixed on one end face of the cleaning strip 15 near the glass plate 7.

[0034] An electromagnet 8 is installed on the top of the chassis 1 and directly below the cleaning strip 15. A magnetic strip is embedded in the bottom of the cleaning strip 15, and the magnetic strip and the opposite surface of the electromagnet 8 are in a state of magnetic repulsion.

[0035] Hollow slides 11 are fixed to the opposite sides of the two suction pipes 10, and universal balls 12 that limit rolling inside the hollow slides 11 are installed on both sides of the cleaning strip 15.

[0036] A stop bar 13 is fixed between the opposing surfaces of the two hollow slide blocks 11 and at the end away from the cleaning strip 15. Springs 14 are fixed on both sides of the stop bar 13 near the end face of the cleaning strip 15. When the cleaning strip 15 collides with the springs 14, the cleaning strip 15 rebounds under the elastic action of the springs 14, causing the cleaning strip 15 to descend and reset. No manual reset is required, realizing the reciprocating movement of the cleaning strip 15, which is more convenient.

[0037] During use, the electromagnet 8 is activated to generate a magnetic field that repels the magnetic strip at the bottom of the cleaning strip 15. Under the effect of magnetic repulsion, the cleaning strip 15 is moved away from the electromagnet 8 and along the direction of the hollow slide 11. During the movement, the rubber scraper 16 will contact the inner wall surface of the glass plate 7 to clean the inner wall surface of the glass plate 7, improving the clarity of observation for the staff. The movement of the cleaning strip 15 is driven by magnetic repulsion, eliminating the need for manual wiping and reducing the workload of wiping.

[0038] Based on embodiments 1-2, the working principle of this utility model is as follows: the servo motor 5 drives the grinding disc 4 to rotate at high speed. Holding the denture, both hands enter the inner cavity of the dust baffle 6 from both sides. At this time, the denture is held by both hands, and the denture is manipulated to contact the high-speed rotating grinding disc 4 to achieve grinding of the denture.

[0039] Dust baffle 6 blocks the dust, controls the direction of dust movement, and prevents the dust from spreading in the direction of the workers.

[0040] At the same time, the vacuum cleaner 31 generates negative pressure, causing dust to enter the interior of the vacuum pipe 10 through the suction holes on the suction pipe 10. Finally, the dust enters the interior of the mesh filter cartridge 33 through the three-way pipe 35, the dust inlet pipe 34, and the dust outlet pipe 32. The dust can be collected as soon as it is raised, which is conducive to achieving dust-free polishing and has a protective effect on the environment and workers.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
