Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding wire buffer. Background Art

[0002] During the welding process, the welding wire keeps feeding forward along the feeding direction. In this case, the welding wire can only move forward at a pre-set speed and is in an uncontrolled state. This leads to welding problems such as unstable wire feeding, welding spatter, wire explosion and poor weld quality when the welding state changes during the welding process.

[0003] According to the application number 202320457485.1, a welding robot wire buffer is provided, in which a welding wire reel is used as the main body, and two sides of the front of the welding wire reel are opened, and a pressure plate that can move back and forth up and down is provided above the opening, and a roller that is driven to rotate by a first motor is provided below the opening. At the same time, a back plate is provided below the middle of the welding wire reel, and a splint that is driven to reciprocate by a cylinder is provided above the middle. During use, the welding wire passes through the two rollers, and the pressure plate presses and limits the welding wire. The rotation of the rollers can drive the welding wire to move, and the welding wire can be fixed in place by the pressure plate and the back plate to prevent the welding wire from shaking back and forth and affecting welding.

[0004] However, the above-mentioned welding wire buffer has certain shortcomings. The buffer only presses the welding wire on the roller through the pressure plate. When the welding wire is unstable in wire feeding and moves up and down, the pressure plate that buffers the welding wire will also move up and down at the same time, which can easily cause the welding wire to detach from the roller, resulting in the pressure plate being unable to stably press the welding wire on the roller, resulting in wire jamming, which then has certain shortcomings. In addition, the buffer can only play a buffering role and has no function for cleaning the welding wire. For this reason, we propose a welding wire buffer. Utility Model Content
