The air intake body 3312 has an air intake channel 3312A for air intake. The air intake channel 3312A is connected to the sandblasting channel 3311A. In this way, the sand is supplied through the sandblasting channel 3311A and the air is supplied through the air intake channel 3312A, so that the sand in the sandblasting channel 3311A can be sprayed toward the workpiece 200, thereby sandblasting the upper end surface 210, the side end 230 and the lower end surface 220 of the workpiece 200.

[0091] The air intake bodies 3312 of the first sandblasting member 331 and the third sandblasting member 333 each include a connecting body 3312B connected to the sandblasting drive assembly 31 and a bending body 3313C connected to the connecting body 3312B, the bending body 3313C extends toward the first rotating member 22 rotated to the sandblasting position 12, the air intake channel 3312A is formed in the connecting body 3312B and the bending body 3313C, and the bending bodies 3313C of the first sandblasting member 331 and the third sandblasting member 333 are arranged relatively to sandblast the upper end face 210 and the lower end face 220 of the workpiece 200, respectively. In this way, the sand material ejected from the bending body 3313C can face the upper end face 210 and the lower end face 220 of the workpiece 200, and the sandblasting effect of the workpiece 200 is better.

[0092] In this embodiment, the second sandblasting component 332 only has a connecting body 3312B, and the sand material sprayed by the second sandblasting component 332 can be directly sprayed toward the side end 230 of the workpiece 200 along the second direction. The distance between the second sandblasting component 332 and the side end 230 of the workpiece 200 remains unchanged during the sandblasting process.

[0093] In this embodiment, the first sandblasting component 331 , the second sandblasting component 332 and the third sandblasting component 333 are made of aluminum alloy, and nozzles are provided inside the first sandblasting component 331 , the second sandblasting component 332 and the third sandblasting component 333 , and the material of the nozzles is boron carbide.

[0094] Please continue to see Figure 1The sandblasting device 100 further includes a sand recovery mechanism 40 and a cyclone separator 50. The sand recovery mechanism 40 includes a recovery bin 41, a recovery pipeline 42 and a sand replenishing assembly 43. The recovery bin 41 is provided on the sandblasting frame 32 and is located below the sandblasting position 12, and is used to collect the sand after sandblasting. The two ends of the recovery pipeline 42 are respectively connected to the recovery bin 41 and the cyclone separator 50, and are used to transport the sand in the recovery bin 41 to the cyclone separator 50. The sand replenishing assembly 43 is connected to the recovery bin 41, and is used to replenish the sand when the height of the sand in the recovery bin 41 reaches a preset position; the cyclone separator 50 is provided on the sandblasting frame 32 and is respectively connected to the first sandblasting component 331, the second sandblasting component 332 and the third sandblasting component 333, so as to separate the sand transported to the recovery pipeline 42 and supply the separated sand to the first sandblasting component 331, the second sandblasting component 332 and the third sandblasting component 333. It can be understood that a certain amount of sand is pre-loaded in the sand replenishment component 43. When the height of the sand in the recovery bin 41 reaches the lowest position, the valve of the sand replenishment component 43 can be opened to put the sand in the sand replenishment component 43 into the recovery bin 41 to realize automatic replenishment of the sand. It can be understood that the gas in the cyclone separator 50 can drive the sand to produce centrifugal action during the rotation process, and throw the particles with a density greater than the gas toward the wall of the device. The particles lose inertial force when in contact with the wall and fall along the wall, enter the sand storage bin and are supplied to the first sandblasting part 331, the second sandblasting part 332 and the third sandblasting part 333; when the rotating and descending external swirling airflow reaches the vertebral body, it moves closer to the center of the cyclone separator 50 due to the contraction of the cone, and its tangential speed continues to increase. When the airflow reaches the sand storage bin at the lower end of the vertebral body, it swirls from the bottom to the top in the cyclone separator 50 in the same rotation direction, continues to make spiral motion, and is discharged to the outside.

[0095] In some embodiments, the sandblasting device 100 further includes a dust removal mechanism 60, which is connected to the cyclone separator 50 and is used to filter the gas discharged from the cyclone separator 50. It can be understood that during dust removal, the dust-containing air discharged from the cyclone separator 50 enters the secondary separator in the dust removal mechanism 60, and the dust-containing air is filtered by liquid water, and the dust is filtered by the water and precipitated to the bottom of the water, while the clean air is brought to the top by the air pressure to enter the powder mist screen layer for filtration, and finally discharged through the air outlet on the upper side of the dust-containing air.

[0096] The implementation process of the sandblasting device 100 of the embodiment of the present application is as follows:

[0097] The second connecting member 335 is moved relative to the first connecting member 334 in the first direction and the third direction, and the rotating member 337 is rotated to adjust the positions and sandblasting angles of the first sandblasting member 331, the second sandblasting member 332 and the third sandblasting member 333;

[0098] The workpiece 200 is sleeved on the contoured portion 232 of the second rotating member 23 of the material loading and unloading position 11 to fix the workpiece 200;

[0099] The first rotating member 21 drives the first rotating member 22 to drive the second rotating member 24 and the workpiece 200 on the second rotating member 23 to rotate from the loading and unloading position 11 to the sandblasting position 12;

[0100] The first sandblasting driving member 311 drives the second sandblasting driving member 312 to move along the first direction, the second sandblasting driving member 312 drives the sandblasting assembly 33 to move along the second direction, and the second rotating driving member 24 drives the second rotating member 23 to rotate, so that the first sandblasting member 331, the second sandblasting member 332 and the third sandblasting member 333 respectively sandblast the upper end surface 210, the side end 230 and the lower end surface 220 of the workpiece 200 rotated to the sandblasting position 12;

[0101] The first rotary drive member 21 drives the first rotating member 22 to drive the second rotary drive member 24 and the second rotating member 23 to rotate the sandblasted workpiece 200 from the sandblasting position 12 to the loading and unloading position 11 for unloading.

[0102] The positions and blasting angles of the first blasting part 331, the second blasting part 332 and the third blasting part 333 of the blasting device 100 of the present application can be adjusted, so that the surface of the workpiece 200 can be sandblasted uniformly, which is convenient for switching and adjusting workpieces 200 of different diameters and lengths. The sand material can be automatically replenished when the sand material is insufficient; the sand material can fall into the recovery bin 41 after use, and after being separated by the cyclone separator 50, it can be transported to the first blasting part 331, the second blasting part 332 and the third blasting part 333 for continued use, which can realize the recycling of the sand material, thereby reducing costs.
