Description

Technical Field

[0001] The utility model relates to the technical field of porcelain tooth processing, in particular to a sandblasting lathe for porcelain tooth processing. Background Art

[0002] Porcelain teeth are restorative crowns that restore tooth defects and meet functional and aesthetic requirements. Structurally, they are divided into inner crowns and glazed porcelain layers, and in terms of texture, they are divided into metal inner crowns and all-ceramic inner crowns. During the processing of porcelain teeth, sandblasting machines are usually used to polish the surface of the porcelain teeth to ensure the beauty and cleanliness of the teeth.

[0003] After searching, it is found that a Chinese patent document discloses a sandblasting lathe for porcelain teeth processing [application number: CN202321182363.2]. This porcelain teeth processing sandblasting lathe includes a manual sandblasting machine, a screening mechanism and a height adjustment mechanism. A fixed frame is installed on the sand dropout port at the lower end of the manual sandblasting machine, a conical material storage bin is installed at the lower end of the fixed frame, a sand outlet frame is installed at the lower end of the conical material storage bin, a sand blasting tube is installed on the side wall of the sand outlet frame, and one end of the sand blasting tube away from the sand outlet frame passes through the side wall of the manual sandblasting machine and is connected to the sand blasting head inside the manual sandblasting machine.

[0004] The lathe disclosed in this patent can filter and screen the sand when in use to reduce the possibility of large-particle impurities clogging the sandblasting tube and the sandblasting gun. However, after long-term use, the sieve holes on the surface of the sieve plate in the lathe are prone to clogging, and the position of the sieve plate is relatively fixed, making it difficult for staff to remove, clean or replace the sieve plate. Over time, the screening efficiency of the sieve plate will be affected, which will affect the use of the sand. In addition, the sieved sand in the lathe accumulates inside the sand outlet frame. If a large amount of sand is accumulated inside the sand outlet frame and it needs to be idle for a long time, the accumulated sand will easily clump and affect the subsequent sandblasting use. Utility Model Content

[0005] The utility model aims to provide a sandblasting lathe for processing porcelain teeth to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a sandblasting lathe for porcelain tooth processing, a base plate and a material storage box, and also includes:

The position of the return frame 10 is fixed, and a rectangular groove is provided on the top of the return frame 10. The depth of the rectangular groove is equal to the height of the return frame 10, and the area of ​​the cross section of the rectangular groove is smaller than the area of ​​the top of the sieve plate 9. Accordingly, the top of the sieve plate 9 can be pressed and limited by the return frame 10. A plurality of positioning rods 11 are fixedly connected to the bottom of the return frame 10, and a plurality of positioning grooves 12 are provided on the top of the lower bin 7. The surface of the positioning rod 11 is slidably connected to the inner wall of the positioning groove 12, and the installation position of the return frame 10 can be limited so that it can pass The return frame 10 can better suppress and limit the top of the sieve plate 9. The surface of the inner wall of the lower silo 7 and the support plate 14 are fixedly connected below the cross plate 8. The storage box 13 is fixedly connected to the bottom of the lower silo 7. A conveying mechanism 17 is installed on the top of the support plate 14. Both sides of the top of the support plate 14 are fixedly connected with guide blocks 15. Through the setting of the guide blocks 15, the screened sand can be guided to the bottom of the lower silo 7 to reduce the possibility of sand accumulation on the support plate 14. The surface of the storage box 13 is connected to a sandblasting pipe 18.

[0026] The adjusting mechanism 6 comprises a rotating shaft 61, a turbine 62, a worm 63 and a turntable 64. One end of the rotating shaft 61 is rotatably connected to the inner wall of the hollow box 5, and the other end of the rotating shaft 61 rotates through the hollow box 5 and is fixedly connected to one end of the connecting rod 4.

The worm 63 meshes with the turbine 62, and the other end of the worm 63 rotates through the hollow box 5 and is fixedly connected to the turntable 64. When the staff rotates the turntable 64, the worm 63 drives the turbine 62 to rotate, and the connecting rod 4 can be driven to rotate through the rotating shaft 61, so as to adjust the state of the cam 41. When the staff does not rotate the turntable 64, the worm 63 and the turbine 62 cooperate to achieve self-locking, and the connecting rod 4 can be fixed.

[0027] The conveying mechanism 17 includes a motor 171 and an auger 172. The motor 171 is fixedly connected to the top of the support plate 14. The bottom of the auger 172 is rotatably connected to the bottom of the inner wall of the storage box 13. The top of the auger 172 rotates through the support plate 14 and is fixedly connected to the output shaft of the motor 171. The outer diameter of the auger 172 is smaller than the cross-sectional area of ​​the sandblasting machine body 3. Accordingly, the sand can be smoothly dropped into the storage box 13 and stored in the storage box 13. At the same time, when the sand is idle for a long time, the staff can start the motor 171 regularly, and the auger 172 can rotate to continuously convey the sand below upward. In this process, the continuous rising and falling of the sand can reduce the possibility of agglomeration of the sand due to accumulation.

[0028] An arc plate 16 is fixedly connected between the two guide blocks 15, and the arc plate 16 is located above the motor 171. Accordingly, the sand falling from the top of the motor 171 can be blocked and guided by the arc plate 16 to reduce the impact of the sand on the normal use of the motor 171. It should be noted that when the motor 171 in the lathe is installed, the power cord connected to it can pass through the lower bin 7. Accordingly, the staff can start the motor 171 by connecting the power cord to an external socket strip, and the vibrator fixed at the bottom of the horizontal plate 8 can be started in the same way. This is an existing mature technology and will not be elaborated here.

[0029] Working principle: The staff pours the sand into the inside of the sandblasting machine body 3 and starts the vibrator. At this time, the cross plate 8 transmits the vibration to the surface of the screen plate 9, and the sand on the surface of the screen plate 9 can be screened by the vibration of the screen plate 9. The screened sand falls into the inside of the lower bin 7 and can be stored in the storage box 13. After the lathe has been used for a long time, the staff can rotate the turntable 64, and the worm 63 and the turbine 62 are used in conjunction to drive the shaft 61 to rotate, and the connecting rod 4 can drive the cam 41 to rotate to release the fixation of the cam 41 to the return frame 10. Then the staff The return frame 10 can be pried upwards first to release the contact between the positioning rod 11 and the inner wall of the positioning groove 12, and then the return frame 10 can be tilted to remove the return frame 10. After that, the staff can take out the screen plate 9 and replace or clean it to ensure the subsequent screening effect of the screen plate 9. When the sand stored in the storage box 13 in the lathe needs to be retained for a long time, the staff can start the motor 171 regularly, and the auger 172 can rotate to transport the sand to reduce the possibility of agglomeration of the sand due to long-term accumulation, thereby ensuring the subsequent use effect of the sand.
