Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic feeding equipment, and in particular to an automatic feeding equipment for welding head wire feeding. Background Technology
[0002] An automatic wire feeder is a self-driven mechanized wire feeding device, mainly used for automatic wire feeding in manual welding, automatic TIG welding, automatic plasma welding, and automatic laser welding. The automatic wire feeder achieves automatic wire feeding to the welding head by combining an advanced microcomputer control system with a precision mechanical transmission mechanism. The microcomputer control system can precisely control the speed of the wire feeding motor and the wire feeding time according to preset welding parameters, ensuring that the welding wire is fed to the welding head at a stable speed and accurate length. Simultaneously, the transmission components in the wire feeding mechanism, such as the wire feeding wheel and the wire guide tube, work closely together to smoothly draw the welding wire from the wire storage hopper, and after straightening and length setting, accurately deliver it to the welding head position, thus realizing automatic feeding during the welding process and greatly improving welding efficiency and quality.
[0003] In existing technologies, when an automatic wire feeder automatically feeds the welding head, impurities such as oil, rust, moisture, and dust may be present on the surface of the welding wire. During the welding process, these impurities will enter the molten pool, affecting the chemical composition and microstructure of the weld metal. For example, oil and moisture decompose at high temperatures to produce gas, which can easily form pores in the weld. Oxides in rust can reduce the strength and toughness of the weld metal, leading to defects such as cracks in the weld. Due to the lack of cleaning measures for the welding wire during the feeding process, it is inconvenient to clean the welding wire during the feeding process, making it difficult to remove residual oil, dust, and other impurities from the upper end of the welding wire, which can easily affect the subsequent welding effect. Utility Model Content
[0004] The main purpose of this utility model is to provide an automatic wire feeding device for welding heads, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An automatic wire feeding device for welding heads includes an automatic wire feeder. The automatic wire feeder has a wire feeding assembly and a wire feeding disc inside. The front end of the automatic wire feeder has a wire outlet. The front end of the wire outlet has a cleaning mechanism. The cleaning mechanism includes a connecting cylinder, a cleaning cotton column, a bidirectional screw, an L-shaped plate, and a limiting rod. The cleaning cotton column is fixedly connected inside the connecting cylinder. The bidirectional screw is movably connected to the recess of the second concave side plate on the outer wall of the connecting cylinder through rotating rods at both ends. The two L-shaped plates are movably connected to the bidirectional screw through screw holes on their top surfaces. Limiting rods are fixedly connected to the opposite walls of the L-shaped plates.
[0007] Preferably, a fixing ring is fixedly installed at the front end of the wire outlet, and a set of symmetrical positioning blocks are fixedly installed on the front wall of the fixing ring.
[0008] Preferably, a first concave side plate is fixedly installed on the outer wall of the fixing ring, and limit holes are respectively opened on the upper and lower end walls of the concave opening of the first concave side plate.
[0009] Preferably, the front end wall of the connecting cylinder has a through hole, and the rear end wall of the connecting cylinder has a positioning port corresponding to the positioning block. A set of symmetrical limiting strips are fixedly installed on the inner wall of the connecting cylinder.
[0010] Preferably, a set of symmetrical limiting grooves corresponding to the limiting strips are provided on the outer wall of the cleaning cotton column, and a through-hole is provided on the front wall of the cleaning cotton column.
[0011] Preferably, a second concave side plate is fixedly installed on the outer wall of the connecting cylinder, and a rotating hole is respectively opened on the upper and lower end walls of the concave opening of the second concave side plate. A guide bar is fixedly installed on the inner side wall of the concave opening of the second concave side plate. A rotating rod is fixedly installed on the upper and lower ends of the bidirectional screw, and the rotating rod is movably installed in the rotating hole. A knob is fixedly installed on the top end of the upper rotating rod. The L-shaped plate is provided with a set of symmetrical upper and lower parts, and a screw hole is opened in front of the top face of the vertical part of the L-shaped plate and threadedly connected to the bidirectional screw through the screw hole. A guide groove corresponding to the guide bar is opened on the side wall of the horizontal part of the L-shaped plate, and a limit rod is fixedly installed behind the outer side wall of the vertical part of the L-shaped plate. The limit rod is inserted into the limit hole.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In this invention, the cleaning mechanism uses a limiting groove and a limiting strip to limit the cleaning cotton column into the connecting cylinder. The connecting cylinder is then positioned and installed at the front end of the fixing ring via a positioning port and a positioning block. Rotating the knob drives the bidirectional screw to rotate, causing the symmetrical L-shaped plates to move in opposite directions along the bidirectional screw through their screw holes until the limiting rod is inserted into the limiting hole. The cleaning mechanism is then fixed at the front end of the wire outlet. When the welding wire passes through the wire hole of the cleaning cotton column, the cleaning cotton column makes full contact with the welding wire, adsorbing or wiping away surface impurities, preventing these impurities from entering the molten pool. This effectively removes residual oil, dust, rust, and other impurities from the welding wire during the welding wire feeding process, effectively cleaning the welding wire and ensuring subsequent welding results.

Detailed Implementation
[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] like Figure 1 - Figure 4As shown, an automatic wire feeding device for welding heads includes an automatic wire feeder 1. The automatic wire feeder 1 has a wire feeding assembly 2 and a wire feeding disc 3 inside. The front end of the automatic wire feeder 1 has a wire outlet 4. The front end of the wire outlet 4 has a cleaning mechanism 5. The cleaning mechanism 5 includes a connecting cylinder 10, a cleaning cotton column 14, a bidirectional screw 20, an L-shaped plate 23, and a limiting rod 26. The cleaning cotton column 14 is fixedly connected inside the connecting cylinder 10. The bidirectional screw 20 is movably connected to the recess of the second concave side plate 17 on the outer wall of the connecting cylinder 10 through rotating rods 21 at both ends. The two L-shaped plates 23 are movably connected to the bidirectional screw 20 through screw holes 24 on the top surface, and the limiting rods 26 are fixedly connected to the opposite side walls of the L-shaped plates 23.
[0021] like Figure 3 As shown, a fixing ring 6 is fixedly installed at the front end of the wire outlet 4, and a set of symmetrical positioning blocks 7 are fixedly installed on the front wall of the fixing ring 6. The positioning blocks 7 on the fixing ring 6 are used to cooperate with the positioning port 12 to achieve positioning and installation of the connecting cylinder 10.
[0022] like Figure 3 As shown, a first concave side plate 8 is fixedly installed on the outer wall of the fixing ring 6, and limit holes 9 are respectively opened on the upper and lower end walls of the concave opening of the first concave side plate 8. The limit holes 9 are used to cooperate with the limit rod 26 to limit the connection and fix the connecting cylinder 10.
[0023] like Figure 4 As shown, a through hole 11 is provided on the front wall of the connecting cylinder 10, which ensures that the welding wire passes through the connecting cylinder 10. A positioning port 12 corresponding to the positioning block 7 is provided on the rear wall of the connecting cylinder 10. The connecting cylinder 10 can be positioned and installed at the front end of the fixing ring 6 through the positioning port 12. A set of symmetrical limiting strips 13 are fixedly installed on the inner wall of the connecting cylinder 10. The limiting strips 13 are used to cooperate with the limiting groove 15 to limit the installation of the connecting cylinder 10.
[0024] like Figure 4 As shown, a set of symmetrical limiting grooves 15 corresponding to the limiting strips 13 are provided on the outer wall of the cleaning cotton column 14, and a through wire hole 16 is provided on the front end wall of the cleaning cotton column 14. The cleaning cotton column 14 can be limited and installed on the inner wall of the connecting cylinder 10 through the limiting grooves 15. When the welding wire passes through the wire hole 16, the cleaning cotton column 14 is in full contact with the welding wire to adsorb or wipe away surface impurities, so as to play a cleaning role when the welding wire is automatically fed.
[0025] like Figure 4As shown, a second concave side plate 17 is fixedly installed on the outer wall of the connecting cylinder 10, and rotating holes 18 are respectively opened on the upper and lower end walls of the concave opening of the second concave side plate 17. A guide bar 19 is fixedly installed on the inner side wall of the concave opening of the second concave side plate 17. Rotating rods 21 are fixedly installed on the upper and lower ends of the bidirectional screw 20, and the rotating rods 21 are movably installed in the rotating holes 18. A knob 22 is fixedly installed on the top end of the upper rotating rod 21. An L-shaped plate 23 is provided with a symmetrical set of upper and lower parts, and a screw hole 24 is opened in front of the top face of the vertical part of the L-shaped plate 23, and is threadedly connected to the bidirectional screw 20 through the screw hole 24. The horizontal sidewall of the L-shaped plate 23 is provided with a guide groove 25 corresponding to the guide bar 19, and a limit rod 26 is fixedly installed behind the vertical sidewall of the L-shaped plate 23. The limit rod 26 is inserted into the limit hole 9. Rotating the knob 22 drives the bidirectional screw 20 to rotate through the rotating rod 21, so that the upper and lower symmetrical L-shaped plates 23 can move relative or oppositely through the screw hole 24 and the guide groove 25 along the bidirectional screw 20 and the guide bar 19 respectively, so that the limit rod 26 can move in and out of the limit hole 9, thereby installing or removing the connecting cylinder 10. After the connecting cylinder 10 is disassembled, the cleaning cotton column 14 inside can be replaced.
[0026] The specific operating principle of the cleaning mechanism 5 in conjunction with the automatic wire feeder 1 is as follows:
[0027] The cleaning cotton column 14 is pre-installed inside the connecting cylinder 10, with the limiting groove 15 on the outer wall of the cleaning cotton column 14 aligning with the limiting strip 13 installed on the inner wall of the connecting cylinder 10. The cleaning cotton column 14 is then positioned within the connecting cylinder 10, with the limiting strip 13 placed in the limiting groove 15. The connecting cylinder 10 is then installed onto the front end of the fixing ring 6, allowing the positioning block 7 at the front end of the fixing ring 6 to enter the positioning port 12 at the rear end of the connecting cylinder 10, thus achieving rapid positioning and installation of the connecting cylinder 10. Simultaneously, the vertical portions of the symmetrical L-shaped plates 23 are positioned in the first concave shape. Within the recess of side plate 8, rotating knob 22 drives rotating rod 21 to rotate within the rotating holes 18 at the upper and lower ends of the recess in the second concave side plate 17. Rotating rod 21 drives bidirectional screw 20 to rotate. During rotation, bidirectional screw 20 forces the symmetrical L-shaped plates 23 to move in opposite directions along bidirectional screw 20 through the screw holes 24 on the top surface of the vertical part. Furthermore, the L-shaped plates 23 will slide along the guide strip 19 installed on the inner wall of the recess in the second concave side plate 17 through the guide groove 25 on the side wall of the horizontal part. Continuously rotating knob 22... 2. After the L-shaped plate 23 moves, the limiting rod 26 is inserted into the limiting hole 9 on the upper and lower end walls of the recess of the first concave side plate 8, and the knob 22 cannot be turned. Then the connecting cylinder 10 can be installed and fixed on the front end of the fixing ring 6. When the welding wire on the wire feeding tray 3 passes through the wire feeding assembly 2, and the wire feeding assembly 2 feeds the welding wire out from the wire outlet 4, the welding wire will pass through the wire hole 16 on the front wall of the cleaning cotton column 14 and the through hole 11 on the front wall of the connecting cylinder 10 in sequence. When the welding wire passes through the wire hole 16 of the cleaning cotton column 14, the cleaning cotton column 14 will interact with the welding wire. By ensuring full contact and adsorbing or wiping away surface impurities, these impurities are prevented from entering the molten pool. This effectively removes residual oil, dust, rust, and other impurities from the surface of the welding wire during the welding wire feeding process, and effectively cleans the welding wire, thereby ensuring the subsequent welding effect. When it is necessary to replace the cleaning cotton column 14, rotate the knob 22 in the opposite direction to move the L-shaped plate 23 relative to it, and after the limiting rod 26 is moved out of the limiting hole 9, remove the connecting cylinder 10 from the front end of the fixing ring 6. Finally, remove the cleaning cotton column 14 from the connecting cylinder 10 for replacement.
