Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a rust removal device for hardware accessories. Background Art

[0002] Hardware: Traditional hardware products, also known as "small hardware", refer to five metals: gold, silver, copper, iron and tin. They can be made into works of art or metal devices such as knives and swords through manual processing. Common rust removal methods for hardware include chemical rust removal, electrochemical rust removal, sandblasting, manual rust removal and roller burnishing. Sandblasting is faster and more convenient than other rust removal methods. Sandblasting machine is a kind of machine powered by compressed air. The high-speed movement of airflow forms a negative pressure in the spray gun. The abrasive is sucked into the spray gun through the sand delivery pipe and sprayed onto the processing surface through the nozzle, thereby achieving the desired processing purpose.

[0003] The existing sandblasting rust removal method generally places the hardware on a support frame and then uses a nozzle to blast the rust. However, during this process, the hardware is basically in a stationary state, so it needs to be manually turned over to ensure that the hardware accessories can be fully rusted. This method is not only time-consuming and labor-intensive, but also has a relatively low rust removal efficiency, which increases the labor intensity of workers. Long-term exposure to rust may cause harm to the workers' health. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the hardware parts are basically in a stationary state during sandblasting and rust removal, and need to be turned over manually to ensure that the hardware parts can be fully rust-removed, which results in low efficiency.

[0006] As a further solution of the present invention, the driving mechanism includes a second motor, which is located above the rust removal box. The output end of the second motor is provided with a driving gear. The support frame includes a support column and a placement rack. The support column is rotatably connected to the rust removal box. The upper end of the support column extending out of the rust removal box is provided with a driven gear meshing with the driving gear. The placement rack is located at one end of the support column extending into the rust removal box and is evenly distributed with several of them. The sandblasting heads are all positioned higher than the placement rack.

[0007] As a further solution of the present invention, the knocking blocks are the same in number as the cams and correspond to the positions of the cams, and the cams are staggered.

[0008] As a further solution of the present invention, a switch door is hingedly provided on the front of the rust removal box, and a controller is provided in front of the switch door.

[0009] As a further solution of the present invention, a protective cover capable of protecting the driving mechanism is provided on the rust removal box.

[0010] As a further solution of the present invention, at least four placement racks are provided, and the number of the sandblasting heads on each side is the same as the number of placement racks.

[0011] The advantages of the present invention over the prior art are that: by setting a vibration mechanism, the motor drives the rotating shaft to rotate, the rotating shaft drives the cam to rotate, the cam alternately hits the knocking block, thereby driving the rust removal box to vibrate, and the rust removal box drives the support frame to vibrate, so that the hardware accessories on the support frame are automatically turned over, thereby ensuring that sandblasting can comprehensively remove rust from the hardware, replacing manual labor and improving work efficiency.
