Description

Technical Field

[0001] This utility model relates to the field of loading and unloading devices, and in particular to a fast loading and unloading device for a hook-type shot blasting machine. Background Technology

[0002] Shot blasting machines, also known as sandblasting machines or shot blasting machines, are casting equipment that uses high-speed shot blasting devices to clean or strengthen the surface of castings. They can remove sand, cores, and clean castings, and can also be used to remove burrs, diaphragms, and rust. Compared with other surface treatment equipment, they are faster and more efficient, and are therefore widely used in various metal casting and steel production industries.

[0003] When existing shot blasting machines are used to blast workpieces, workers need to first operate the machine to move the hook holding the workpiece into the cleaning chamber, then manually close and lock the chamber door, and finally start the two shot blasters and open the shot supply gate to carry out the cleaning operation. After the cleaning is completed, the above steps must be repeated to remove the workpiece. This makes it impossible to quickly load and unload workpieces, which leads to a reduction in the efficiency of cleaning or strengthening workpieces. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick loading and unloading device for a hook-type shot blasting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] In this invention, the controller starts the drive motor to rotate, which in turn drives the threaded rod to rotate. The threaded rod controls the adjusting blocks at both ends to move to the sides. At this time, the scissor cross frame retracts, causing the fixed block to move to the left. When the hook on the fixed block carries the workpiece into the shot blasting box, the telescopic blocks on both sides of the control block on the telescopic cylinder will contact the top of the movable block. At this time, the telescopic block will drive the movable block to move to the left. When the movable block moves to the left, the connecting rod can drive the movable door to close. When the movable block moves to the far left, the telescopic block continues to move to the left. At this time, the outer side of the telescopic block is pressured and moves into the telescopic groove. The top of the movable block will be stuck between the telescopic block and the stop block, which facilitates the subsequent opening of the movable door. This achieves automatic and rapid loading and unloading of workpieces without manual operation by workers, improving the efficiency of workpiece cleaning and strengthening.
