[0002] Welding, also known as fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials by heating at high temperature or high pressure. There are many energy sources for modern welding, including gas flame, arc, laser, electron beam, friction, and ultrasound.
[0003] Currently, the existing wire drawing wire feeding mechanism for welding does not have the function of removing dust from the welding wire. When the welding wire has been stored for a long time and there is dust attached to its outer side, directly using it for welding is likely to cause a decline in welding quality and may even cause welding defects, thus there are certain deficiencies. In addition, the existing wire drawing wire feeding mechanism can only feed welding wires with a fixed diameter specification. However, according to different processing requirements, the diameter specification of the welding wire will change, and the current wire drawing wire feeding mechanism is not convenient to adjust according to the requirements, thus there are also certain deficiencies. For this reason, we have proposed a wire drawing wire feeding mechanism. Content of the Utility Model

Inside the housing 1, two first rotating shafts 2 are rotatably installed. On the outer sides of one ends of the two first rotating shafts 2, synchronous pulleys 3 are fixedly installed. A first belt 4 is installed on the outer sides of the two synchronous pulleys 3. On the back of the housing 1, a driving motor 5 is fixedly installed. The output end of the driving motor 5 is fixedly connected to one end of a first rotating shaft 2. On one end of the other first rotating shaft 2, a transmission pulley 6 is fixedly installed. Inside the housing 1, a second rotating shaft 7 is rotatably installed. On the outer side of one end of the second rotating shaft 7, a driven pulley 8 is fixedly installed. A second belt 9 is installed on the outer sides of the transmission pulley 6 and the driven pulley 8. On the other end of the second rotating shaft 7, a disc 10 is fixedly installed. On the outer side of the disc 10, a connecting rod 11 is rotatably installed. On the top inside the housing 1, two guide rods 12 are fixedly installed. On the outer sides of the guide rods 12, a concave seat 13 is slidably installed. Inside the concave seat 13, a hole matching the guide rod 12 is opened. One end of the connecting rod 11 is movably connected to the bottom of the concave seat 13. Inside the concave seat 13, two sponge wipes 14 are fixedly installed.
[0025] On the other end of the first rotating shaft 2, a wire feeding wheel 15 is fixedly installed. On the top of the housing 1, a threaded rod 16 is rotatably installed. On the outer side of the threaded rod 16, a sleeve plate 17 is threadedly installed. Inside the sleeve plate 17, a hole matching the threaded rod 16 is opened. On both sides of the bottom of the sleeve plate 17, mounting rods 18 are fixedly installed. One end of the mounting rod 18 extends to the inside of the housing 1 and a mounting seat 19 is fixedly installed. Inside the mounting seat 19, a pressing wheel 20 is rotatably installed. On one end of the threaded rod 16, a grip turntable 21 is fixedly installed. On the top of the housing 1, a benchmark 22 is fixedly installed. The benchmark 22 is slidably connected to the sleeve plate 17. Inside the sleeve plate 17, a hole matching the benchmark 22 is opened. On the outer side of the benchmark 22, an adjustment mark 23 is provided. The sleeve plate 17 cooperates with the adjustment mark 23.
[0026] On the outer side of the bottom of the threaded rod 16, a gear 24 is fixedly installed. On the top of the housing 1, two vertical plates 25 are fixedly installed. Inside the vertical plates 25, a sliding rod 26 is slidably installed. On one end of the sliding rod 26, a tooth 27 is fixedly installed. The tooth 27 cooperates with the gear 24. On the outer side of the sliding rod 26, a resisting plate 28 is fixedly installed. A spring 29 is installed on the outer side of the sliding rod 26, and on the other end of the sliding rod 26, a pulling plate 30 is fixedly installed. Among them, the functions of the gear 24, the vertical plate 25, the sliding rod 26, the tooth 27, the resisting plate 28, the spring 29 and the pulling plate 30 are to limit and fix the threaded rod 16, to avoid the threaded rod 16 being accidentally touched and rotated, resulting in the offset of the sleeve plate 17 and affecting the wire drawing and guiding operation of the cooperation between the pressing wheel 20 and the wire feeding wheel 15.
[0027] Inside the housing 1, a welding wire reel is provided. Inside one side of the housing 1, a wire guiding hole is provided. On one side of the housing 1, a wire guiding nozzle is provided.
[0028] In summary, when the wire drawing and wire feeding mechanism is in use, first adjust the distance between the pressing wheel 20 and the wire feeding wheel 15 according to the diameter of the welding wire that needs to be drawn and fed. When adjusting, first pull the side pull plate 30 laterally, and then make the sliding rod 26 drive the locking tooth 27 to move laterally, so as to release the limit on the gear 24 and the threaded rod 16. Subsequently, rotate the grip turntable 21 to make the threaded rod 16 rotate, and then drive the sleeve plate 17 to displace through the thread, so as to adjust the distance between the pressing wheel 20 and the wire feeding wheel 15 according to the cooperation of welding wires of different diameters. During the adjustment, the adjustment distance can be known by observing the adjustment marks 23 on the outer side of the sleeve plate 17 and the benchmark 22. After the adjustment is completed, release the pull plate 30, and the spring 29 rebounds to push the abutting plate 28 to reset the sliding rod 26 and the locking tooth 27, so that the gear 24 can be clamped by the locking tooth 27 to limit the threaded rod 16. Subsequently, start wire drawing and wire feeding. Pass the welding wire on the welding wire reel through the middle parts of the wire feeding wheel 15 and the pressing wheel 20, and then start the driving motor 5. Drive the first rotating shaft 2 by the driving motor 5 to make the wire feeding wheel 15 rotate, and then the welding wire can be drawn and fed. At the same time of wire feeding, pass one end of the welding wire through the inside of the two sponge wipes 14, and then lead it out through the wire guiding hole and the wire guiding nozzle for welding use. When the driving motor 5 drives the first rotating shaft 2 to rotate, the two synchronous belt wheels 3 can be driven to rotate simultaneously by the first belt 4, and at the same time, the transmission belt wheel 6 will also be driven to rotate. The transmission belt wheel 6 drives the driven belt wheel 8 through the second belt 9 to make the second rotating shaft 7 and the disc 10 rotate, and then the concave seat 13 can be driven to reciprocate up and down outside the guide rod 12 through the connecting rod 11. During the movement, the welding wire passing through the middle part of the sponge wipe 14 can be dust-removed. The design is ingenious, which improves the firmness and welding quality of the subsequent welding of the welding wire.
