Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to a sandblasting machine capable of evenly stirring abrasives. Background Art

[0002] Sandblasting machine, also known as sandblasting equipment or sandblaster, is a processing equipment commonly used for surface treatment of flat shells. It is used for cleaning, polishing, pre-spraying treatment, removal of oxide layers and coatings, etc. The sandblasting machine sprays abrasive or sandblasting particles at high speed and impacts them onto the surface of the object being processed to remove unwanted impurities and improve surface quality and roughness.

[0003] The existing sandblasting machine simplifies the structure and reduces the difficulty of operation when in use, thereby achieving the effect of uniform stirring and reducing the waste of human resources. For example, the existing Chinese patent application number: CN206622993U discloses a sandblasting machine that stirs abrasives evenly. This solution sprays out through a sandblasting tube, and there is no problem of stirring the abrasive and water, so that the abrasive is stirred more evenly, avoiding affecting the treatment effect on the treated workpiece, improving the qualified rate of produced workpieces, saving a lot of manpower and material resources, and improving people's work efficiency. A motor is fixedly connected to the bottom of the inner wall of the sandblasting machine body, and the output shaft of the motor is connected to the rotating shaft through a belt drive. One end of the rotating shaft is rotatably connected to a rotating device, and one side of the rotating device is fixedly connected to a stirring shaft, and the end of the stirring shaft away from the rotating device is fixedly connected to a turntable, and one side of the turntable is fixedly connected to a stirring rod, which improves the sandblasting effect of the sandblasting machine and reduces manual operation. This structure is simple and easy to operate.

[0004] During the feeding process, the current sandblasting machine will throw the raw materials into the equipment all at once, causing a large number of particles to be concentrated in one place of the grinding disc. This is not only not conducive to the grinding of the particles, but the accumulation of particles will also aggravate the wear of the grinding disc, causing the spacing between the grinding discs to gradually increase. Therefore, since the effect of uniform feeding cannot be achieved, the ground particles will appear too large or too small, which is not conducive to the treatment and cleaning of the flat shell surface. At the same time, the different particle sizes will also reduce the uniformity of the abrasive and the spraying effect, thereby reducing the treatment quality of the flat shell.
