Description

Technical Field

[0001] This utility model relates to the technical field of metal workpiece cleaning tools, and in particular to a drum-type metal workpiece cleaning and sandblasting machine. Background Technology

[0002] Before the advent of drum-type sandblasting machines, the surface cleaning of metal workpieces mainly relied on methods such as manual grinding, chemical cleaning, and simple mechanical brushing. Manual grinding depended on manual operation, which was extremely inefficient and labor-intensive for workers. For complex-shaped metal workpieces, it was difficult to ensure that all parts were treated evenly, resulting in inconsistent surface quality. Although chemical cleaning could remove oil and some rust to a certain extent, it generated a large amount of wastewater, causing environmental pollution. Moreover, it was not effective in cleaning stubborn oxide scale, sand casting residues, and other impurities. Simple mechanical brushing equipment had limited functions and could not perform deep cleaning and roughening treatment on the workpiece surface, making it difficult to meet the high requirements of modern industry for the surface quality of metal workpieces. In modern industrial production, the surface treatment of metal workpieces is crucial. As an important surface treatment equipment, the drum-type metal workpiece cleaning sandblasting machine was born and developed with a profound technological background and driven by practical needs.

[0003] While existing drum-type sandblasting machines can improve the cleanliness of metal workpieces, the sand sprayed from the gun also remains on the workpieces, increasing sand waste and processing costs. Furthermore, existing drums only use a simple rotation method, and the excess sand sprayed from the gun is not effectively utilized on the metal workpieces, resulting in unsatisfactory cleaning effects. Therefore, these problems need to be addressed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drum-type metal workpiece cleaning and sandblasting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drum-type metal workpiece cleaning and sandblasting machine, comprising a main body, support rods equidistantly installed at four ends on the outer side of the main body, a cleaning cylinder installed inside the main body, a transmission mechanism installed at the bottom end of the cleaning cylinder, a cleaning mechanism installed at the other end of the cleaning cylinder, and a recycling mechanism installed inside the main body.

[0006] Preferably, the cleaning mechanism includes an electric push rod inverted and mounted on the top of the main body. The telescopic end of the electric push rod is hinged to a U-shaped mounting base. A spray gun is mounted on the bottom end of the mounting base. The spray gun is connected to a pipeline on the outside of the main body.

[0007] Preferably, the transmission mechanism includes a motor installed inside the main body, a first gear installed at the output end of the motor, a second gear meshing with one side of the first gear, a rotating rod fixedly connected to the upper end of the second gear, the rotating rod being engaged with the bottom end of the cleaning cylinder, and both the first gear and the second gear being rotatably installed inside the main body.

[0008] Preferably, the recycling mechanism includes a fan installed on the top of the main body and a filter screen installed at the bottom of the main body, with a solenoid valve installed at the bottom of the filter screen, and the solenoid valve is located at the bottom of the main body.

[0009] Preferably, handles are installed on both sides of the cleaning cylinder, and multiple sand plates are installed at equal intervals on the inner side of the cleaning cylinder.

[0010] Preferably, the cleaning cylinder is installed at an angle inside the main body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of a fan and a filter screen, facilitates the downward blowing of excess sand on metal workpieces, which is then blown into the lower end of the filter screen for storage and reuse. This avoids sand waste and reduces processing costs. Furthermore, through the cooperation of a sanding plate and a cleaning cylinder, the sand collides with the sanding plate during rotation, thereby driving the sand to perform secondary friction on the metal workpieces, improving the cleaning effect. Ultimately, this solves the problems of existing devices that waste sand, increase costs, and have unsatisfactory cleaning effects. Attached Figure Description
