Description

Technical Field

[0001] This utility model relates to the field of welding wire processing technology, specifically to a powder coating device for welding wire processing. Background Technology

[0002] Welding wire is a metal wire welding material, mainly used as filler metal or as a conductive metal wire in the welding process. In order to protect the welding wire from moisture and oxidation and to ensure welding quality and efficiency, powder is applied to the surface of the welding wire after processing.

[0003] According to CN220027633U, a powder coating device for welding wire processing includes a storage tank with a storage cavity at the top. The storage cavity has through holes at both ends of the storage tank. Four sealing flaps are installed near the openings of the two through holes, forming a complete circle within the same through hole. A cover plate is provided at the top of the storage tank, with a square groove at its top. The welding wire, as it passes through the storage tank, will have no blind spots in contact with the powder coating, quickly completing the powder coating operation. The sealing flaps installed on the inner walls of both through holes allow welding wires of different outer diameters to pass through the storage tank normally without leakage. This ensures that the powder coating inside the storage tank is at normal air pressure, preventing powder splashing and leakage. The device can support the entire apparatus while the storage tank is normally coating the welding wire, and can also be rotated to the top for easy lifting and carrying.

[0004] The aforementioned storage tank and other structures can effectively prevent paint powder from splashing and leaking. However, during the process of coating the welding wire, the welding wire needs to be inserted through the through hole at one end and pulled out through the through hole at the other end. This makes it impossible to perform multiple welding wire coating operations simultaneously, thus reducing the coating efficiency. Utility Model Content

[0023] By installing the welding wire into the mounting hole of the powder coating box 1 and passing it through the guide groove 207 on the surface of the two conveying rollers 206, the rotary motor 201 is started, causing the drive shaft 202 and drive gear 203 to rotate. The transmission gear 204 rotates accordingly, driving the transmission shaft 205 to rotate, causing the two conveying rollers 206 to rotate in opposite directions, thereby conveying multiple welding wires into the storage chamber 9. After the powder coating is completed, the rotary motor 201 on the other side works, causing the two conveying rollers 206 on that side to rotate in opposite directions, thereby removing the welding wire from the powder coating box 1, reducing the workload of personnel and improving the powder coating efficiency of the device.

[0024] The powder coating box 1 has mounting holes on its left and right sides. The drive shaft 202 and the transmission shaft 205 are rotatably connected to the powder coating box 1.

A guide rod 7 is slidably connected to the middle of the slider 5.

[0026] By rotating the handle on the bidirectional lead screw 4, it is made to rotate. At the same time, the slider 5 drives the two cleaning brushes 6 to move towards each other, and the direction of movement is guided by the guide rod 7. After moving to a suitable height, the cleaning brushes 6 come into contact with the welding wire. During the movement of the welding wire, the dust and foreign objects on its surface can be cleaned to avoid affecting the normal powder coating of the welding wire.

[0027] There are two connecting frames 3. The guide rod 7 is located inside the connecting frame 3. The top of the bidirectional screw 4 is equipped with a rotating handle. There are two cleaning brushes 6.

[0028] An observation window 8 is fixedly connected to the front of the powder coating box 1. A storage chamber 9 is provided inside the powder coating box 1.

The pump 15 is then activated to pump the coating powder from the storage tank connected to it into the connecting pipe 16 and spray it out through the discharge plate 17. Because the welding wire is preheated, the coating powder can adhere more easily to the surface of the welding wire, which facilitates the coating of the welding wire.

[0032] This utility model provides a powder coating device for welding wire processing, and its specific working principle is as follows:

[0033] In use, the welding wire is installed into the mounting hole of the powder coating box 1 and passed between the guide grooves 207 on the surfaces of the two conveying rollers 206. The rotary motor 201 is started, causing the drive shaft 202 and drive gear 203 to rotate. The transmission gear 204 rotates accordingly, driving the transmission shaft 205 to rotate, causing the two conveying rollers 206 to rotate in opposite directions, thereby conveying multiple welding wires into the storage chamber 9. While the welding wire is moving, its surface comes into contact with the cleaning brush 6, thereby cleaning the dust and foreign objects on its surface. After the welding area of ​​the welding wire moves above the heat-conducting plate 13, Start the first electric push rod 10, causing its output rod to drive the mounting frame 11 to move up and down. After the heat-conducting plate 13 comes into contact with the welding wire, the resistance wire 12 is activated to heat the welding area of ​​the welding wire.
