[0026] Based on the above embodiment 1, please refer to Figures 3-5The bottom surface of the inclined plate 303 is in contact with the top surface of the turntable 204. The top surface of the turntable 204 is opened at an angle. The top surface and the two side surfaces of the inclined plate 303 are fixedly connected to the inner wall of the working frame 205. The rotating groove 304 is used for the rotation of the mounting column 208. The connecting column 305 is installed on the middle inner wall of the turntable 204. The inner wall of the connecting column 305 is connected to the inner wall of the blowing plate 306.

[0031] The working principle and usage process of this utility model are as follows: The watch case to be sandblasted is fixed on the mounting block 210 on the turntable 204, ensuring a firm fixation to prevent movement or detachment during the sandblasting process. The position and angle of the watch case are adjusted as needed to ensure that the sandblasting evenly covers the entire surface of the case.

[0032] Monitor the sandblasting process: Closely observe the sandblasting process, checking for uniformity and any abnormalities in the sandblasting effect on the watch case. If uneven sandblasting or abnormalities are detected, immediately stop the sandblasting process and inspect the equipment or adjust the parameters.

[0033] Abrasive Collection: During sandblasting, the abrasive circulation system collects scattered abrasive into the storage hopper, achieving abrasive recycling. Simultaneously, the collection block 301 in the collection assembly 3 collects abrasive falling from the edge of the turntable 204, preventing it from scattering within the working area. The collection groove 302 on the collection block 301 is designed with an inclined plate 303 to facilitate the abrasive sliding into the collection frame 308. The rotation groove 304 on the inclined plate 303 ensures that the mounting column 208 does not interfere with the inclined plate 303 during rotation. It should be noted that the rotation of the turntable 204 during use does not hinder the sandblasting cleaning of the turntable 204 by the blower plate 306; they can operate synchronously.

[0034] Air blowing cleaning: After sandblasting, activate the high-pressure airflow of the air blower plate 306, blowing high-pressure air through the air outlet 307 to blow the residual abrasive on the turntable 204 into the collection frame 308. The air blowing process should continue for a period of time to ensure that there is no residual abrasive on the surface of the turntable 204. After thorough cleaning, turn off the power and air supply of the equipment, and wait for the turntable 204 to completely stop rotating. Manually clean the abrasive in the collection frame 308 and pour it back into the storage hopper for later use.
