Technical Field

[0001] The utility model relates to the technical field of wire feeders, in particular to a wire feeder with a cleaning function. Background Technique

[0002] A wire feeder is a mechanical device used to automatically transport welding wires in welding equipment. It improves the efficiency and quality of welding operations through an automated method. The wire feeder is mainly used in the automatic welding process. It replaces manual operation and stably and continuously feeds the welding wire into the welding area.

[0003] Chinese Patent CN220127816U discloses a resistance adjustment device for a flux-cored wire feeder, including an adjustment box. A top of an inner cavity of the adjustment box is fixedly connected with an adjustment assembly, and a bottom of the adjustment assembly is fixedly connected with an upper concave frame. By setting the adjustment box, the adjustment assembly, the upper concave frame, the upper guide roller, the lower concave frame, the lower guide roller, the flux-cored wire body, the power assembly, and the cleaning assembly, a resistance adjustment device for a flux-cored wire feeder is jointly constructed. Among them, the height of the upper guide roller can be adjusted through the adjustment assembly, and then the extrusion force on the welding wire can be adjusted, thereby adjusting the resistance of the welding wire to avoid the welding wire from becoming loose during the wire feeding process. Through the setting of the power assembly, the lower guide roller on the right side can be driven to rotate, and then the flux-cored wire can be driven to be transported to the right side to complete the wire feeding. Through the setting of the cleaning assembly, the dust adhered to the surface of the flux-cored wire body can be removed.

[0004] In the above patent, the cost is relatively high by setting two electric push rods to adjust the brush plate. After the brush plate has been cleaning the welding wire for a long time, the brush plate will also be damaged to a certain extent by the welding wire, and a large amount of dust will adhere to the brush plate. Since it is inconvenient to replace the brush plate, the cleaning effect on the welding wire is affected. Content of the Utility Model

[0007] Further, the left end of the top surface of the base is fixedly connected with a wire feeding box, the cross section of the fixing frame is U-shaped, the cross section of the movable block is an isosceles trapezoid, and the length of the lower end of the movable block is less than that of the upper end, the inclined surfaces of the convex block and the movable block are fixedly connected, and the cross section of the connecting groove is convex-shaped.

[0008] Further, there are two fixing rods which are parallel to each other, the fixing rods are respectively located on the front and rear sides of the movable plate, both ends of the fixing rods are horizontally fixedly connected with the inner wall of the fixing frame, and a sliding groove for slidably connecting with the slider is horizontally formed at the center of the fixing rod.

[0009] Further, two fixing shafts are horizontally fixedly connected between the fixing frames, the fixing shafts are located in front of the connecting plate and below the fixing rod, and roller shafts are rotatably connected to the outer walls of the fixing shafts.

[0010] Further, the driving block is slidably connected with the connecting plate, the driving block is located on the left side of the connecting rod, a worm gear is fixedly connected to the outer wall of the right end of the lead screw and is located on the right side of the through groove, a worm is horizontally meshed with the outer wall of the worm gear, the worm is located below the worm gear, one end of the worm is rotatably connected with the connecting plate, the other end of the worm is rotatably connected with and passes through a support plate, the cross section of the support plate is L-shaped, and the support plate is fixedly connected with the connecting plate.

[0011] Further, the cleaning brush is in contact with the connecting plate, the centers of the two cleaning brushes and the centers of the two roller shafts are on the same horizontal line, and are also on the same horizontal line as the center of the wire feeding hole on the wire feeding box.

[0012] Compared with the prior art, the beneficial effects achieved by the present utility model are:

[0013] 1. The utility model starts the cylinder according to the diameter of the welding wire. The moving end of the cylinder moves upward to drive the movable block to move upward. The movable block drives the convex block to slide upward in the connecting groove, so that the movable plates move towards each other.

When the cleaning brush needs to be replaced, turn the crank to drive the worm to rotate, which makes the worm wheel rotate and drives the lead screw to rotate. The lead screw makes the driving block slide leftward on the connecting plate. The driving block drives the L-shaped rod to disengage from the fixed groove, and then takes out the connecting rod on the cleaning brush from the through groove. The principle of removing the other cleaning brush is the same as above. When installing the cleaning brush, insert the connecting rod on the cleaning brush into the through groove, and reverse-rotate the crank to insert the L-shaped rod into the fixed groove to complete the replacement. This solves the problem of high cost caused by the need for two electric push rods to adjust the brush plate, realizes the convenient replacement of the brush plate, and improves the cleaning effect of the welding wire.

[0014] 2. The utility model is fixedly connected by setting a fixed shaft and a fixed bracket, and is rotatably connected between the roller shaft and the fixed shaft. When the welding wire moves, since the outermost periphery of the welding wire reel is higher than the top surface of the cleaning brush, when the welding wire moves, there is a risk that the welding wire at the front end of the cleaning brush will break away from the cleaning brush, which will reduce the cleaning effect. By setting the roller shaft, the welding wire can always be between the two cleaning brushes, ensuring the cleaning effect of the welding wire. BRIEF DESCRIPTION OF THE DRAWINGS
