As the welding wire in the welding wire barrel 200 is continuously used, the weight monitored by the weight detection assembly 110 gradually decreases. When the weight decreases to a set threshold, the worker prepares a new welding wire barrel 200 for replacement.

[0093] The moving groove is provided with a limiting plate at both ends.

[0094] In the cross rod 131, the end of the welding wire guide 133 is provided with a protrusion matching the shape of the moving groove, so as to realize the movement of the welding wire guide in the cross rod 131, and the cross rod 131 is provided with a limiting plate at both ends to avoid the welding wire guide 133 from falling off from the cross rod 131, thereby ensuring the reliability of the welding wire guide 133.

[0095] It should be noted that the moving groove can be T-shaped or dovetail-shaped, which can realize the clamping connection between the cross rod 131 and the welding wire guide 133, and enable the welding wire guide 133 to move in the moving groove. The movement of the welding wire guide 133 in the moving groove is to avoid the pulling of the welding wire caused by fixed connection, and the movable connection can further reduce the pulling force of the welding wire during wire feeding, thereby ensuring the reliability and stability of the wire feeding. Sometimes the welding gun needs to be moved to other positions, and the welding wire will be moved together. If the welding wire guide 133 and the cross rod 131 are fixedly connected, the welding gun and the welding wire will be pulled, which is easy to cause the welding wire to break, thereby affecting the wire feeding and welding efficiency.

[0098] Wherein, the welding wire guide 133 can be provided in a detachable form, that is, the welding wire guide 133 comprises the first mounting block 1331 and the second mounting block 1332, so that the feasibility of hoisting the wire sleeve (welding wire) can be improved, and the clamping hole size is prevented from being too large due to the direct threading of the wire sleeve, so that the wire sleeve is prevented from moving too much and the stability of the wire sleeve is affected.

[0099] It should be noted that the first mounting block 1331 is provided with the first arc-shaped through slot 1333 on the side facing the second mounting block 1332, the second mounting block 1332 is provided with the second arc-shaped through slot 1334 on the side facing the first mounting block 1331, the first arc-shaped through slot 1333 and the second arc-shaped through slot 1334 form a clamping hole, the second arc-shaped through slot 1334 is provided with a U-shaped clamping plate at both ends, that is, a receiving groove 1335 is formed, the receiving groove 1335 can accommodate the positions of the two ends of the first arc-shaped through slot 1333, and the detachable connection between the first mounting block 1331 and the second mounting block 1332 is realized by penetrating the positions of the two ends of the first arc-shaped through slot 1333 and the second arc-shaped through slot 1334 with a bolt. It can be understood that the first arc-shaped through slot 1333 can also have a U-shaped clamping plate at both ends, that is, a receiving groove 1335, the extension direction of the receiving groove 1335 is perpendicular to the extension direction of the clamping hole, and then the two ends of the first arc-shaped through slot 1333 can also clamp the two ends of the second arc-shaped through slot 1334 to realize the connection of the first mounting block 1331 and the second mounting block 1332.

[0100] In the embodiment, the first mounting block 1331 is provided with a T-shaped connecting block or a dovetail-shaped connecting block connected with the moving groove.
