[0002] Plasma spraying is a technology for strengthening and modifying the surface of materials. It can make the substrate surface have the properties of wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, friction reduction and sealing. Plasma spraying technology uses a plasma arc driven by direct current as a heat source to heat ceramics, alloys, metals and other materials to a molten or semi-molten state, and sprays them at high speed onto the pre-treated workpiece surface to form a firmly attached surface layer. Plasma spraying is also used for medical purposes. A layer of tens of microns of coating is sprayed on the surface of artificial bones as a method to strengthen artificial bones and enhance their affinity.

[0003] After searching, it is found that the plasma spraying device in the prior art is typically a plasma spraying device such as the one disclosed in CN107447181A, which includes a first plasma generator, a second plasma generator and a plasma mixer, wherein the first plasma generator includes a first vacuum tube, a first set of electrodes, a first gas through hole and a first acceleration coil, wherein a cavity is arranged inside the first vacuum tube, the first set of electrodes includes a cathode and an anode, and the first gas inlet through hole is arranged on the end face of the first vacuum tube. The main feature of the plasma spraying device is that the two spraying materials can be mixed and sprayed at the same time.

[0004] In summary, the existing plasma spraying structure is prone to produce a large amount of water mist due to the sudden cooling and vaporization of high-temperature materials during spraying, which can easily cause pollution and impact on the working environment and subsequent spraying quality inspection. In view of the above problems, the existing equipment needs to be improved. Utility Model Content

[0005] The purpose of the utility model is to provide a plasma anti-fog spray module to solve the problem that the existing plasma spray structure proposed in the above background technology is prone to produce a large amount of water mist due to the sudden cooling and vaporization of high-temperature materials during spraying, which in turn easily causes pollution and influence on the working environment and subsequent spray quality detection.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a plasma anti-fog spraying module, including a module fixing bracket and a slider,

[0007] The module fixing bracket is provided with a reciprocating mechanism, and the reciprocating mechanism includes a frame, a driving shaft, a transmission belt, a motor and a slide rail. The frame is provided with a driving shaft, and the driving shafts are connected with each other through a transmission belt, and the driving shaft is connected with the output end of the motor.

[0008] The slider is arranged on the transmission belt, and the top of the slider is connected with a mounting frame, the bottom of the mounting frame is connected with a suction pipe, and a plasma spray head is arranged on one side of the suction pipe.

[0009] Preferably, a dustproof plate is provided on the top of the module fixing bracket, and the dustproof plate is arranged above the frame.

[0010] Preferably, a slide rail is installed on the frame, and the slide rail is arranged on one side of the transmission belt.

[0011] Preferably, the slide rail is slidably connected to the slider, and two groups of slide rails are provided.

[0012] Preferably, the mounting frame is symmetrically provided with limit plates, and the inner side of the limit plates is slidably connected with an adjustment plate.

[0013] Preferably, the adjustment plate is connected to the mounting frame via a connecting piece, and the adjustment plate is connected to the plasma spray head via a sleeve ring.

[0014] Preferably, the plasma spray heads are symmetrically arranged on both sides of the mounting frame, and the plasma spray heads are snap-connected inside the collar.

[0015] Preferably, suction heads are distributed at equal intervals on the bottom of the suction pipe, and the suction pipe is symmetrically arranged on the inner side of the plasma spray head.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the plasma anti-fog spraying module,

[0017] (1) The utility model can effectively solve the problem that the existing plasma spraying structure is prone to generate a large amount of water mist due to the sudden cooling and vaporization of high-temperature materials during spraying, which can easily pollute and affect the working environment and subsequent spraying quality inspection. Driven by the external suction device, multiple groups of suction heads on the suction pipe will simultaneously suck the mist generated by the plasma spraying head during operation, thereby preventing it from diffusing and polluting the working environment and affecting the subsequent spraying quality inspection, thereby ensuring the spraying quality;

[0018] (2) The utility model can effectively solve the problem of uneven spraying in most existing plasma spraying equipments, which is prone to single and fixed spraying positions, by using a reciprocating mechanism and a slider. The motor drives the drive shaft to rotate forward and reversely. When the drive shaft rotates, the drive belt drives the plasma spray head on the mounting frame to move back and forth along the slide rail, thereby avoiding the occurrence of dead spots in spraying due to the single spraying position. At the same time, the arrangement of two groups of plasma spray heads can enable the device to perform two spraying processes in succession, thereby improving the uniformity of spraying and ensuring the spraying quality.
