Description

Technical Field

[0001] This utility model relates to the field of porcelain crown processing technology, specifically to a wear-resistant porcelain crown surface treatment device. Background Technology

[0002] Porcelain veneers are a type of tooth restoration that involves fusing a layer of porcelain powder onto a metal inner core to restore the shape and function of the tooth. Porcelain veneers look very similar to natural teeth, and their color can be adjusted to achieve a natural appearance. They are particularly suitable for repairing teeth with significant damage.

[0003] Existing patent CN222968904U discloses a sterilization device for porcelain crown production, relating to the field of porcelain crown production. It includes a sterilization chamber with ultraviolet germicidal lamps connected to its left and right inner walls. A support plate is connected inside the sterilization chamber, and a rotating box is connected to the top of the support plate. The top of the rotating box has multiple placement openings. A bidirectional lead screw is connected inside the rotating box, and two moving blocks are connected to the outer wall of the bidirectional lead screw. Each of the two moving blocks has a connecting rod connected to its top. This invention utilizes the bidirectional lead screw to rotate, causing the two moving blocks to move. The moving blocks pull the connecting rods, which in turn pull the sealing plates, moving the sealing plates towards the left and right openings of the rotating box. As the sealing plates gradually move, the porcelain crowns in the placement openings gradually fall into the collection box. Once the sealing plates are completely removed from the multiple placement openings, all the porcelain crowns in the placement openings fall into the collection box, allowing for convenient and rapid collection of sterilized porcelain crowns.

[0004] The current production of porcelain crowns requires multiple processes, such as sandblasting and acid etching. During acid etching, the porcelain crowns usually pile up together, which reduces the etching efficiency. Moreover, they need to be removed one by one after etching, which can increase the fatigue of the operator and reduce their practicality. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 as well as Figure 3This utility model provides a technical solution: a wear-resistant porcelain crown surface treatment device, including an acid tank 1, a placement box 11 inside the acid tank 1, an anti-accumulation component inside the placement box 11, and a discharge component on the outside of the placement box 11. The anti-accumulation component includes a horizontal plate 21 fixedly connected to the top of the placement box 11, a first motor 22 fixedly connected to the top of the horizontal plate 21, a stirring shaft 23 fixedly connected to the bottom of the first motor 22, blades 24 connected to a fixed rod on the outside of the stirring shaft 23, and multiple liquid inlets 25 evenly arranged on both sides of the bottom of the placement box 11. The stirring shaft 23 is rotatably connected to the horizontal plate 21. Porcelain crowns can also be placed in the placement box 11. The first motor 22 can drive the stirring shaft 23 to rotate, and the rotation of the stirring shaft 23 can drive the blades 24 to rotate. The rotation of the blades 24 can also agitate the porcelain crowns in the placement box 11, thereby preventing the porcelain crowns from accumulating and allowing the porcelain crowns to fully react with the acid. Liquid contact can improve the acid etching efficiency of porcelain crowns. A bracket 51 is fixedly connected to the outside of the acid tank 1, and a cylinder 52 is fixedly connected to the top of the bracket 51. The output end of the cylinder 52 is fixedly connected to the top of the fixing frame 31. The cylinder 52 can push the fixing frame 31 to move vertically, which in turn can drive the placement box 11 to move vertically, allowing the placement box 11 to move in and out of the acid tank 1. Guide rods 61 are fixedly connected to both sides of the top of the fixing frame 31. Openings 62 are opened on both sides of the top of the bracket 51. The guide rods 61 are slidably connected to the openings 62. The movement of the fixing frame 31 can drive the guide rods 61 to move vertically. The guide rods 61 can improve the vertical movement stability of the fixing frame 31 and prevent the fixing frame 31 from tilting. A drain pipe 81 is fixedly connected to one side of the acid tank 1. A control valve 82 is installed on the outside of the drain pipe 81. The drain pipe 81 can facilitate the discharge of acid in the acid tank 1, and the control valve 82 can facilitate the opening and closing of the drain pipe 81.

[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4The discharge component includes a fixed frame 31, a first rotating shaft 32 connected to one side of the fixed frame 31, a second rotating shaft 33 connected to the other side of the fixed frame 31, a driven gear 34 fixedly connected to the outer side of the second rotating shaft 33, a master gear 35 connected to the driven gear 34, a drive shaft 36 fixedly connected to the master gear 35, and a second motor 37 fixedly connected to one end of the drive shaft 36. The master gear 35 meshes with the driven gear 34. Both the first rotating shaft 32 and the second rotating shaft 33 are rotatably connected to the fixed frame 31. The first rotating shaft 32, the second rotating shaft 33, and the drive shaft 36 are all fixedly connected to the placement box 11. The second motor 37 can drive the drive shaft 36 and the master gear 35 to rotate, and the master gear 35 can drive the driven gear 34 to rotate, thereby controlling the rotation of the second rotating shaft 33 and the placement box 11. The placement box 11 facilitates the removal of porcelain crowns, allowing for quick removal and improving material discharge efficiency. Rotating grooves 41 are provided on both sides of the fixing frame 31, with rotating blocks 42 slidably connected to both sides of each groove 41. The rotating blocks 42 are fixedly connected to the placement box 11; rotation of the placement box 11 drives the rotating blocks 42 to rotate, improving the stability of the placement box 11's rotation and preventing it from tilting. A protective cover 71 is fixedly connected to one side of the fixing frame 31 on the second rotating shaft 33. The protective cover 71 covers the main gear 35, the driven gear 34, and the second motor 37, protecting them from acid corrosion.

[0025] Working principle: During operation, the porcelain crown is placed in the placement box 11. Then, cylinder 52 is activated, which pushes the fixing frame 31 downward. The downward movement of the fixing frame 31 causes the placement box 11 to move downward, allowing it to enter the acid tank 1. Then, the first motor 22 is activated, which drives the stirring shaft 23 to rotate. The rotation of the stirring shaft 23 drives the blades 24 to rotate, which in turn rotates the porcelain crown, thus agitating it. This ensures that the acid solution fully contacts the porcelain crown, improving the etching efficiency. After etching is complete, cylinder 52 is activated again, causing the fixing frame 31 to move upward. The device moves and resets, which in turn moves and resets the placement box 11. Then, the second motor 37 is started. The operation of the second motor 37 drives the drive shaft 36 to rotate. The rotation of the drive shaft 36 drives the main gear 35 to rotate. The rotation of the main gear 35 drives the driven gear 34 to rotate. The rotation of the driven gear 34 drives the second rotating shaft 33 and the placement box 11 to rotate. All the porcelain crowns in the placement box 11 can be discharged. The porcelain crowns can be collected through the box to prevent them from falling into the acid tank 1. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
