Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting, in particular to an anti-corrosion plastic-coated steel pipe shot blasting device. Background Art

[0002] Shot blasting is an important mechanical surface treatment process. A high-speed rotating impeller propels small steel or iron shots onto the surface of a workpiece to clean or strengthen it. Shot blasting removes impurities such as oxide layers and rust from the workpiece's surface, improving its appearance. Furthermore, the high-speed impact deforms the workpiece's surface lattice, increasing surface hardness and achieving a strengthening effect. Furthermore, shot blasting is widely used for cleaning casting surfaces and strengthening parts, offering advantages such as high efficiency and minimal pollution. Shot blasting also plays a vital role in shipbuilding, automotive parts manufacturing, and aircraft component manufacturing.

[0003] Before the plastic coating process of anti-corrosion plastic-coated steel pipes is carried out, the steel pipes must be shot blasted to ensure the cleanliness and roughness of the steel pipe surface. Since the steel pipe is cylindrical, it cannot rotate in the shot blasting machine, which results in the steel shot ejected by the shot blasting machine not being able to evenly cover every part of the steel pipe. In order to overcome this problem, special measures need to be taken, such as using specially designed clamps to fix the steel pipe so that it can maintain a certain angle and position during the shot blasting process, thereby ensuring that the steel shot can evenly hit the surface of the steel pipe and achieve the desired shot blasting effect. To this end, an anti-corrosion plastic-coated steel pipe shot blasting device is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-corrosion plastic-coated steel pipe shot blasting device to solve the problem in the prior art that the steel shots ejected by the shot blasting machine cannot evenly cover the steel pipe.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-corrosion plastic-coated steel pipe shot blasting device, comprising a shot blaster, a collection shell is provided below the shot blaster, a recovery pipe is fixedly installed at the bottom of the collection shell, a screen plate is fixedly installed at the upper end of the collection shell, a positioning mechanism is provided above the screen plate, the positioning mechanism comprises a positioning guide rail fixedly installed in the collection shell, a threaded sleeve fixedly installed on the collection shell at one end, a fixed frame is fixedly installed at one end of the positioning guide rail, a second conical seat is rotatably installed on the fixed frame, and a sliding seat is installed on the positioning guide rail. There is a sliding frame, on which a first conical seat is rotatably mounted, an adjusting screw is installed on the inner thread of the threaded sleeve, and the end of the adjusting screw is rotatably connected to the sliding frame, and the second conical seat is connected to a driving mechanism, and the driving mechanism includes a driven pulley fixedly mounted on the second conical seat and a driving motor fixedly mounted in the collecting shell, a driving gear is fixedly mounted on the output end of the driving motor, a reduction gear is movably mounted on one side of the driving gear, a movable shaft is fixedly mounted on the reduction gear, and a driving pulley is fixedly mounted on the movable shaft.

[0006] Preferably, a hand wheel is fixedly mounted on the adjusting screw, a rotary connector is provided at the end of the adjusting screw, and the adjusting screw is rotatably mounted on the sliding frame through the rotary connector.

[0007] Preferably, a mounting opening is provided on the collection shell, the threaded sleeve is mounted on the collection shell through the mounting opening, the sliding frame is movably mounted in the collection shell through a positioning guide rail, and the first conical seat is movably mounted on one side of the second conical seat through the sliding frame.

[0008] Preferably, the adjusting screw is installed on one side of the collecting shell through a threaded sleeve.

[0009] Preferably, a toothed belt is provided between the driving pulley and the driven pulley.

[0010] Preferably, the reduction gear and the driving pulley are both movably mounted in the collection shell via a movable shaft.

[0011] Preferably, the driving gear is movably mounted on one side of the reduction gear through a driving motor, and the driving gear is meshed with the reduction gear.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In this application, operating the handwheel causes the sliding frame to move forward, which in turn pushes the first conical seat forward. The forward movement of the first conical seat allows pipes of different lengths to be secured between the first and second conical seats. Once the pipes are secured, the shot blaster can launch projectiles, thereby achieving shot blasting of steel pipes of different lengths.

[0014] 2. In this application, a drive motor is used to achieve rotational motion of the drive gear. Subsequently, the rotation of the drive gear is transmitted to the reduction gear, which in turn causes the reduction gear to rotate. The rotation of the reduction gear drives the driving pulley, causing it to rotate accordingly. The rotation of the driving pulley drives the driven pulley via a toothed belt, thereby causing the driven pulley to rotate. The rotation of the driven pulley is further transmitted to the second conical seat, causing it to rotate. The rotating second conical seat drives the pipe to rotate through mechanical transmission. Ultimately, the rotation of the pipe ensures that the ejected projectiles evenly cover the surface of the steel pipe. BRIEF DESCRIPTION OF THE DRAWINGS
