Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, and in particular to a sandblasting machine for processing dental prostheses. Background Technology

[0002] Dentures, also known as prostheses, are restorations that replace missing teeth, with the core function of restoring chewing function and oral appearance. They are mainly divided into two categories: fixed dentures and removable dentures, which need to be custom-made based on the patient's oral model. Denture fabrication commonly uses materials such as metal, resin, and ceramics, and is completed through processes such as model design, framework fabrication, and surface molding. Ultimately, they must fit the oral structure to ensure comfortable use.

[0003] In the denture manufacturing process, sandblasting is primarily used to remove wax residue, oxide layers, and oil stains from the model or metal surface. These impurities directly affect the bonding of subsequent materials, such as the bond between the metal framework and resin. Simultaneously, sandblasting allows for fine-tuning of details such as denture edges and occlusal surfaces, removing burrs and flash generated during manufacturing, resulting in a more precise denture shape. Furthermore, sandblasting creates tiny textured surfaces on smooth metal, ceramic, or resin surfaces, increasing the contact area. For example, after sandblasting, the ceramic veneer adheres more firmly to the metal inner crown of the denture, preventing porcelain detachment during use. A sandblasting machine is required for this process.

[0004] A sandblasting device for denture processing disclosed in Chinese Patent CN223353993U allows for adjustment of the precision of denture processing via a sandblasting gun with different inner diameter processing nozzles. This enables both large-area integrated processing and small-area fine processing of dentures, meeting diverse processing needs. However, comparison with existing technologies and comparative solutions reveals the following problems in practical use of this sandblasting device:

[0005] Because sandblasting machines generate a large amount of dust during operation, long-term inhalation can harm the health of operators. Therefore, observation and operation are often conducted through glass windows and with gloves. However, sand or dust easily adheres to the glass windows, obstructing the operator's vision. Cleaning the sand or dust from the glass windows often requires stopping the sandblasting process, leading to reduced work efficiency. Utility Model Content

A first sealing strip 107 is provided on the sandblasting machine body 1. A first sliding rod 108 is fixedly connected inside the working chamber 101.

[0033] like Figure 2 and Figure 5 As shown, the top cover 2 is rotatably connected to the top of the sandblasting machine body 1. An observation window 201 is provided in the middle of the top cover 2, a fixing hook 202 is provided on one side of the top cover 2, and a second sealing strip 203 is provided on the top cover 2.

[0034] like Figure 1 , Figure 2 and Figure 6 As shown, the fixing component 3 includes a connecting plate 301, a second slide rod 302, a fixing seat 303, a limiting block 304, and a first elastic element 305. The connecting plate 301 is rotatably connected to the bottom of one side of the sandblasting machine body 1. The second slide rod 302 is slidably connected to the connecting plate 301. One end of the second slide rod 302 is fixedly connected to the fixing seat 303. The fixing seat 303 is adapted to the fixing hook 202. The end of the second slide rod 302 away from the fixing seat 303 is fixedly connected to the limiting block 304. The first elastic element 305 is provided between the limiting block 304 and the connecting plate 301.

[0035] like Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the cleaning component 4 includes a connecting seat 401, a cleaning brush 402, a connecting rope 403, a connecting ring 404, and a second elastic element 405. The cleaning brush 402 is fixedly connected to the connecting seat 401 by bolts. The position of the cleaning brush 402 corresponds to the position of the observation window 201. In this embodiment, the two sides of the cleaning brush 402 are bristles, and the middle is a cleaning cotton. When in use, it can improve the cleaning effect on the observation window 201. A slider is fixedly connected to the connecting seat 401. The connecting seat 401 is slidably connected to the first slide rod 108 through the slider. The connecting rope 403 is fixedly connected to the connecting seat 401 through the slider.

[0037] The work process is as follows:

[0038] S1. When in use, open the top cover 2, place the denture to be processed in the working cavity 101, close the top cover 2 and fix the top cover 2 by fixing component 3;

[0039] S2. The operator's hand is inserted into the working chamber 101 through the glove 103. One hand holds the denture to be processed, and the other hand holds the sandblasting pen 102. The sandblasting machine body 1 can be turned on to sandblast the denture.

[0040] S3. The sand generated by sandblasting falls into the discharge chute 105 through the mesh plate 104. When cleaning is required, simply open the side door 106.

[0041] S4. When sand or dust sprayed out adheres to the inside of the observation window 201 after a period of use, the operator's foot can pull the connecting rope 403 through the connecting ring 404, and the connecting rope 403 drives the cleaning brush 402 to move through the connecting seat 401.

[0042] S5. After the operator stops applying force with their foot, the second elastic element 405 rebounds, causing the connecting seat 401 to reset. The connecting seat 401 then moves the cleaning brush 402 to clean the inside of the observation window 201. This allows the inside of the observation window 201 to be cleaned during the sandblasting process, preventing sand or dust adhering to the observation window 201 from affecting the operator's vision and improving work efficiency.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
