Description

Technical Field

[0001] The invention relates to the technical field of sandblasting machines, in particular to a self-cleaning sandblasting machine. Background Art

[0002] Sandblasting machine is an important equipment in the category of air conveying machinery. It is mainly used to transport powdered granular materials to a specific location through compressed air, and use these high-speed moving sand particles to scour the surface of the object to improve the quality of the surface of the object. The working principle of the sandblasting machine is mainly based on the power of compressed air. During the sandblasting process, compressed air transports sand particles from the sand bin to the sandblasting gun, and sprays them at high speed to the processed surface through the nozzle. The impact and cutting action of the sand particles can remove dirt, scale, coating, etc. on the surface, and at the same time roughen the surface, which is conducive to subsequent coating adhesion and processing. After the existing sandblasting machine is completed, the sand and gravel are accumulated everywhere and need to be cleaned in time, which is time-consuming and labor-intensive, and has certain limitations. Therefore, it is necessary to design a self-cleaning sandblasting machine to solve the problem. Summary of the invention

[0006] As a preferred technical solution of the present invention, there are several support seats, which are distributed in a circular array. The first push rod motor is located below the support seat, and the number and position are consistent with the support seat. The first push rod motor is used to push out the support seat to support the workpiece. A torsion spring is connected between the support seat and the rotating seat to facilitate the resetting of the support seat and put it into the rotating seat.

[0007] As a preferred technical solution of the present invention, the protective frame adopts a circular ring structure design, and a through groove adapted to the flip frame is opened on one side of the protective frame, which can not only play a protective role and reduce the splashing of sand and gravel, but also will not hinder the flip frame from sandblasting and cleaning.

The sand blasting height can be changed by the second push rod motor, and the sand blasting position can be changed by cooperating with the second electric screw rod. It is suitable for workpieces of different models and heights. At the same time, the flip design of the flip frame will not affect the entry and exit of the workpiece. The sand and gravel are sucked into the central tube through the suction port and discharged by the suction pipe, thereby completing the sand suction work and playing a certain cleaning role. The conversion between sand blasting and sand suction can be realized by controlling the rotation of the second rotating frame and the inlet and outlet pipes through the third driving gear, which is convenient and fast. The first driving gear and the first rotating frame can be used to control the rotation of the rotating seat, thereby changing the direction of the workpiece to achieve the purpose of increasing the sandblasting and cleaning range, and a protective frame can be used to block the sand and gravel during the sandblasting work to reduce its splashing, so as to better concentrate it and send it into the collecting cavity through the discharge pipe for recovery; The first push rod motor is used to push out the support seat to support the workpiece, and each group of the first push rod motor and the support seat are independent of each other. When rotating to the sandblasting and cleaning station, it can be retracted by the torsion spring and supported by the remaining support seat to avoid obstruction during sandblasting and cleaning work and reduce the possibility of dead corners.
