When shot blasting machine for all kinds of workpiece blasting cleaning, the workpiece hangs on special tooling, driven by electric hoist, running along the guide rail to the blasting cleaning room. Shot blasting machine gate and shot blasting machine interlocking device, the door is not closed, the shot blasting device can not start. When the gate is closed, the shot blasting device starts the workpiece, and the workpiece rotates under the rotation of the self rotating motor, so that the workpiece can be cleaned in a comprehensive manner. At this time, the upper part can be operated on another hook to improve efficiency. When the shot blasting machine has completed the cleaning, it closes the shot blasting device and stops the rotation. It is driven by the electric hoist. It is transported along the guide rail and the lower part of the cleaning room. At the same time, the other hook enters the cleaning room to carry out the shot cleaning. The process of cleaning the workpiece is completed according to the program and the work piece.



Main features of double hanger shot blasting machine:

1, the machine adopts no pit structure, easy installation, reduce investment costs.

2. Compact structure, high productivity, good cleaning quality, safe and reliable operation, smooth operation.

3. Hook has three functions of self lifting, walking and indoor rotation.

4, optimize the workpiece surface technology status, increase the paint film adhesion when painting the workpiece.

5. Double hook structure can clean up and work on one side to improve efficiency.

6, with multiple throwing heads, the efficiency of cleaning is greatly improved.

7, a higher degree of automation, to reduce the intensity of cleaning work.
