Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to a sandblasting machine with a protective structure. Background Art

[0002] Sandblasting machines are a type of air conveying machinery. They use compressed air to transport powdered granular materials from one location to another within a pipeline. In the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object, thereby improving the surface quality of the object.

[0003] When producing semiconductor parts, a sandblasting machine is needed to process the semiconductor parts.

[0004] When the existing sandblasting machine is not in use, the nozzle is exposed to the outside and has no protective effect. The residual spray material in the nozzle may drip out of the nozzle, and the staff is required to clean the dripping spray material, which increases the labor of the staff. Utility Model Content

DETAILED DESCRIPTION

[0022] like Figures 1-4As shown, the utility model provides a technical solution: a sandblasting machine with a protective structure, comprising a workbench 1, a support plate 2 fixed on the top of the workbench 1, a sandblasting machine 3 fixed on the top of the support plate 2, a hose 4 fixedly connected to the bottom of the sandblasting machine 3, a connector 5 fixed at one end of the hose 4 away from the sandblasting machine 3, a nozzle 6 fixed at the bottom of the connector 5, and sandblasting operations can be performed by setting the nozzle 6, and an adjustment protection mechanism 7 is provided on the support plate 2.

[0023] Specifically, the adjustment and protection mechanism 7 includes a groove 701, a threaded rod 703, a motor 702, a threaded sleeve 704, a telescopic rod 706, a transmission block 707, a hinged rod 708, a moving block 705, a protective cover 710 and a reset spring 709; the groove 701 is opened on the inner side of the support plate 2, and the inner wall of the groove 701 is rotatably mounted with a threaded rod 703, the bottom of the support plate 2 is fixed with a motor 702, and the output end of the motor 702 is fixedly connected to the outer wall of the threaded rod 703, and then when the motor 702 is started, the threaded rod 703 can be rotated, and the outer wall of the threaded rod 703 is threadedly connected with a threaded sleeve 704, which is slidably mounted in the groove The inner wall of 701, the threaded sleeve 704 is fixed on the side of the connector 5 away from the groove 701, and then when the threaded rod 703 rotates, the threaded sleeve 704 can be moved up and down, and the threaded sleeve 704 can drive the connector 5 to move up and down, and the height of the nozzle 6 can be adjusted according to the size of the parts. The top of the connector 5 is slidably installed with a moving block 705, and the top of the connector 5 is fixed with a telescopic rod 706. The top of the telescopic rod 706 is fixed with a transmission block 707, and the transmission block 707 is hinged with a hinged rod 708. The end of the hinged rod 708 away from the transmission block 707 is hinged on the moving block 705 When sandblasting is not needed, the motor 702 can be controlled to make the threaded rod 703 drive the threaded sleeve 704 to move upward, so that the connector 5 drives the moving block 705 and the telescopic rod 706 to move upward. When the transmission block 707 moves to contact the inner side of the support plate 2, the transmission block 707 will be subjected to an extrusion force, so that the transmission block 707 squeezes the hinged rod 708. There are two groups of moving blocks 705, and the two groups of moving blocks 705 are symmetrically arranged with the center line of the connector 5 in the vertical direction as the symmetry axis, so that the hinged rod 708 can squeeze the two groups of moving blocks 705 close to each other. The side wall of the connector 5 is fixed with a return spring 709, and the return spring 709 is away from the connector. One side of the head 5 is fixed to the inner side of the moving block 705. By setting the reset spring 709, the moving block 705 can be reset. A protective cover 710 is fixed to the side of the moving block 705 away from the hinged rod 708. There are two groups of protective covers 710, and the two groups of protective covers 710 are symmetrically arranged with the center line of the connecting head 5 in the vertical direction as the symmetry axis. When the two groups of moving blocks 705 approach each other, the reset spring 709 is compressed, driving the two groups of protective covers 710 to approach each other. The nozzle 6 at the bottom of the connecting head 5 can be covered by the protective cover 710 to prevent the spray material from dripping from the nozzle 6 when the sandblasting machine 3 is not in use, which is inconvenient to clean.

[0024] Working principle: When sandblasting operation is not required, the motor 702 can be controlled to make the threaded rod 703 drive the threaded sleeve 704 to move upward, so that the connecting head 5 drives the moving block 705 and the telescopic rod 706 to move upward. When the transmission block 707 moves to contact the inner side of the support plate 2, the transmission block 707 will be subjected to an extrusion force, so that the transmission block 707 squeezes the hinged rod 708, so that the hinged rod 708 can squeeze the two groups of moving blocks 705 close to each other. When the two groups of moving blocks 705 are close to each other, the return spring 709 is compressed, driving the two groups of protective covers 710 close to each other. The nozzle 6 at the bottom of the connecting head 5 can be covered by the protective cover 710 to prevent the spray material from dripping from the nozzle 6 when the sandblasting machine 3 is not in use, which is inconvenient to clean.

[0025] When the nozzle 6 needs to be used, the motor 702 can be started to make the threaded rod 703 drive the threaded sleeve 704 to move downward, so that the nozzle 6 can be moved downward, so that the transmission block 707 is not pressurized with the inner side of the support plate 2. Since the reset spring 709 is in a compressed state, the reset spring 709 can drive the moving block 705 to reset, so that the protective cover 710 is removed from the bottom of the nozzle 6, and then the sandblasting operation can be carried out.

[0026] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
