Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of welding machines, in particular to a high-efficiency heat dissipation device for welding machines. Background Art

[0002] As the name suggests, the welding machine ventilation and heat dissipation device is a device for ventilating and dissipating the inside of the welding machine. The welding machine will generate a lot of heat when it is working. If the welding machine is not ventilated and dissipated in time, it will cause damage to the welding machine. The welding machine ventilation and heat dissipation device can ventilate and dissipate the heat of the welding machine.

[0003] Since the heat dissipation device of the welding machine usually stirs the internal and external air through the heat dissipation holes, a dust screen is generally installed on the heat dissipation holes to filter the exchanged air. However, after long-term use of the dust screen, the mesh on the surface of the dust screen will be clogged, which not only reduces the dust filtering effect, but also affects the internal and external air exchange efficiency, thereby reducing the heat dissipation effect and heat dissipation efficiency of the device. Therefore, we propose a high-efficiency heat dissipation device for welding machine to solve the above-mentioned problems. Utility Model Content

The welding machine uses a high-efficiency heat dissipation device, which performs heat dissipation operation on the inside of the device through the heat dissipation mechanism, exchanges the air inside and outside the welding machine body 1 through the heat dissipation holes 2, and filters the exchanged air through the filter 8. When the filter 8 needs to be cleaned, the rotating shaft 5 is rotated, and the filter 8 is synchronously driven to rotate while the rotating shaft 5 rotates. The brush 9 inside the fixing frame 6 continuously rubs against the surface of the filter 8, and then the dust adhered to the filter 8 is cleaned, thereby avoiding the filter 8 being covered with dust and causing clogging of the mesh of the filter 8, thereby improving the filtration efficiency and filtration effect of the filter 8, improving the heat dissipation efficiency of the device, and improving practicality.

This motor is a well-known device purchased directly on the market by technicians in this field. Here we just use it and do not make any structural and functional improvements to it. We will not go into details here. The motor is provided with a control switch matched with it. The installation position of the control switch is selected according to actual practical needs, which is convenient for operators to operate and control. The motor 11 outputs power, and then synchronously drives the blades 12 to rotate at a high speed, thereby accelerating the air circulation inside the welding machine body 1, and exchanges the air inside and outside the welding machine body 1 through the heat dissipation holes 2. The filter 8 filters the exchanged air, and the protective cover 13 is used to protect the parts installed on the outer wall of the welding machine body 1. When the filter 8 needs to be cleaned, the first handle 14 is rotated and the rotating shaft 5 is synchronously driven to rotate. The filter 8 is synchronously driven to rotate while the rotating shaft 5 rotates. The filter 8 is continuously rubbed against the brush 9 installed on the inner wall of the fixing frame 6 to clean the dust stuck on the filter 8. The bottom area of ​​the filter 8 is tightly fitted with the brush 9, so that the filter 8 will not rotate when not in use, and the cleaned dust can be discharged through the dust discharge door at the bottom end of the fixing frame 6.
