Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, specifically a surface rust removal sandblasting machine. Background Technology

[0002] As a key piece of equipment for removing rust and oxide scale from workpiece surfaces in metal processing, machinery repair and other fields, the operation method of surface rust removal sandblasting machines directly affects the rust removal efficiency and ease of operation.

[0003] Based on the above, the inventors have discovered the following problems: Existing sandblasting machines typically require the user to hold the spray gun throughout the entire process. When sandblasting a workpiece to remove rust, the operator must hold the spray gun firmly with one hand to control the spray direction and angle, while the other hand needs to fix or adjust the workpiece position to ensure the surface to be treated is evenly sprayed. This two-handed operation mode demands a high level of operator skill, especially when dealing with irregularly shaped or large workpieces. It is difficult to simultaneously ensure stable spraying from the spray gun and precise workpiece positioning, easily leading to uneven rust removal, localized missed areas, and other problems, affecting the surface treatment quality of the workpiece.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a surface rust removal sandblasting machine in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a surface rust removal sandblasting machine to solve the problem mentioned in the background art that the spray gun of the existing sandblasting machine usually requires the user to operate it by hand throughout the process.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A surface rust removal sandblasting machine includes a main body and an adjusting mechanism. The main body includes a sandblasting machine body with a material hopper at its bottom and an oil-water separator fixedly installed at its top. The adjusting mechanism includes a mounting frame and a sandblasting gun. One side of the mounting frame is connected to the inner side of the sandblasting machine body. Sliding rods are fixedly installed at both the upper and lower ends of the mounting frame, and movable blocks are slidably installed on each sliding rod. An adjusting frame is fixedly installed between a pair of movable blocks. Rotating shafts are installed on both sides of one end of the sandblasting gun, and the pair of rotating shafts are rotatably connected to the inner sides of the adjusting frame, respectively. Spring-loaded flexible hoses are sleeved on both the output and input ends of the sandblasting gun, and the other ends of the pair of spring-loaded flexible hoses are connected to the oil-water separator and the material hopper, respectively.

[0008] Furthermore, a screw is rotatably connected inside the mounting bracket, and a slider is threaded onto the screw. One side of the slider is fixedly connected to the adjustment bracket.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the screw and the slider are threadedly matched. Rotating the screw can drive the adjusting frame and the sandblasting gun to move precisely along the slide bar. The threaded transmission has high precision and can accurately control the lateral position of the sandblasting gun, ensuring the uniformity of the rust removal operation and avoiding positional deviations caused by manual adjustment.

[0010] Furthermore, a first servo motor is fixedly installed at one end of the sandblasting machine body, and the output end of the first servo motor is connected to the screw drive.

A pair of operating slots are provided on the door, and rubber glove sleeves are installed inside the operating slots.

[0019] The beneficial effects of adopting the above-mentioned further solutions are that the observation window makes it easy for operators to observe the internal rust removal process and adjust the operating parameters in a timely manner; the operating groove on the door and the rubber glove sleeves make it easy for operators to handle the workpiece outside the closed environment, avoiding direct contact with dust and high-speed sand particles, ensuring operational safety, while maintaining the internal sealing of the sandblasting machine body to prevent dust leakage.

[0020] Furthermore, an air compressor is fixedly installed on the upper end of the sandblasting machine body, and the output end of the air compressor is connected to one end of the oil-water separator through a pipe. A hopper cover is installed on the bottom end of the hopper with bolts. A bag filter is fixedly installed on one side of the sandblasting machine body, and the input end of the bag filter is connected to the interior of the sandblasting machine body through a pipe.
