[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-Figure 5 , the technical solution provided by this embodiment is as follows:

[0024] A wire feeding device that can be automatically cleaned includes a wire guide channel piece A5 and a wire guide channel piece B6. The wire guide channel piece A5 and the wire guide channel piece B6 are installed in a lower head seat 1. There is a groove or a pad between the wire guide channel piece A5 and the wire guide channel piece B6. The groove or the gap between the two groups of pads forms a wire guide channel 10. An air intake channel 8 is arranged on the upper part of the wire guide channel 10.

[0025] In a specific embodiment of the utility model, the lower head seat 1 is used to install the wire guide channel plate A5 and the wire guide channel plate B6. A groove or a pad is provided between the wire guide channel plate A5 and the wire guide channel plate B6, so that the groove or the gap between the two groups of pads forms a wire guide channel 10. The setting of the wire guide channel 10 can guide the transported wire, so that the active wire feeding wheel 11 and the driven wire feeding wheel 12 can guide the wire when transporting it in the wire guide channel 10, thereby reducing friction and thus reducing wear when transporting the wire.

[0026] Specifically, the wire feeding assembly includes a wire clamping drive seat 2, a wire clamping drive 3, a wire feeding drive 4, an active wire feeding wheel 11 and a driven wire feeding wheel 12. The wire clamping drive seat 2 is equipped with the wire clamping drive 3, the front end of the wire clamping drive 3 is equipped with a shaft, and the driven wire feeding wheel 12 is rotatably connected to the shaft. The wire feeding drive 4 is located opposite to the wire clamping drive 3, and the output end of the wire feeding drive 4 is equipped with an active wire feeding wheel 11. The active wire feeding wheel 11 and the driven wire feeding wheel 12 are alternately arranged with the wire guide channel 10.

[0027] In a specific embodiment of the utility model, the wire clamping drive seat 2 is located inside the protective cover 16. When the wire enters the wire guiding channel 10, the active wire feeding wheel 11 is driven to rotate by the output end of the wire feeding drive 4, and the driven wire feeding wheel 12 is pushed forward by the wire clamping drive 3. After the driven wire feeding wheel 12 pushes the wire over, the driven wire feeding wheel 12 and the active wire feeding wheel 11 cooperate to clamp the wire and transport the electrode wire downward. The electrode wire can be sent down by the setting of the wire feeding assembly, and the wire threading success rate is high, the number of parts is small, it is easy to assemble and maintain, and the cost is saved.

[0028] Specifically, a positioning shaft is installed on the wire clamping drive 3, and the positioning shaft slides in the wire clamping drive seat 2. A wire guide wheel 17 and a conductive block 15 are installed below the lower head seat 1.

[0029] In a specific embodiment of the present invention, the positioning shaft plays a guiding role, which can more accurately push the driven wire feeding wheel 12 to move, and the wire can be sent to the lower left side of the driven wire feeding wheel 12 through the wire guide channel 10, thereby guiding the wire for transportation.

[0030] Specifically, an air inlet hole 7 is opened on the lower head seat 1 , an air inlet channel 8 is communicated with the air inlet hole 7 , and the wire feeding assembly is installed in the lower head seat 1 .

[0031] In a specific embodiment of the utility model, an air inlet hole 7 is opened on the lower head seat 1, so that the air inlet channel 8 is connected with the air inlet hole 7. A cleaning component can be formed by connecting the air inlet channel 8 with the air inlet hole 7. Air is taken in through the air inlet hole 7, so that the gas is blown out through the air inlet channel 8. The gas blown out through the air inlet channel 8 can blow out foreign matter or waste residue in the guide wire channel 10, thereby improving the cleaning effect of the guide wire channel 10. The active wire feeding wheel 11 and the driven wire feeding wheel 12 are tightly closed, so that the gas blown out of the air inlet channel 8 can clean the eye mold 9. After being processed by the cleaning component, foreign matter or waste residue in the guide wire channel 10 will be blown out and discharged, which can clean the eye mold 9 and allow the electrode wire to enter the guide wire channel 10 from the eye mold 9 better.

[0032] Specifically, it also includes a protective cover 16, an eye mold 9 and an insulating connecting plate 13. The protective cover 16 is installed on the outside of the lower head seat 1, the eye mold 9 is installed on the top of the lower head seat 1, the insulating connecting plate 13 is installed on the left end of the lower head seat 1, and a water baffle 14 is installed on the lower head seat 1.

[0033] In a specific embodiment of the utility model, the internal structure can be protected by the setting of 16, the water baffle 14 can prevent water from splashing out, and the insulating connecting plate 13 is used to connect the lower headstock 1.

[0034] The working principle of the automatically cleanable wire feeding device provided by the utility model is as follows: the conveyed wire can be guided by the setting of the wire guide channel 10, so that the active wire feeding wheel 11 and the driven wire feeding wheel 12 can guide the wire when conveying it in the wire guide channel 10, the active wire feeding wheel 11 is driven to rotate by the rotation of the output end of the wire feeding drive 4, and the driven wire feeding wheel 12 is pushed forward by the wire clamping drive 3. After the driven wire feeding wheel 12 pushes the wire over, the driven wire feeding wheel 12 and the active wire feeding wheel 11 cooperate to clamp the wire, and the electrode wire is conveyed downward, and air is taken in through the air inlet hole 7, so that the gas is blown out through the air inlet channel 8. The gas blown out through the air inlet channel 8 can blow out foreign matter or waste residue in the wire guide channel 10, and the active wire feeding wheel 11 and the driven wire feeding wheel 12 are tightly closed, so that the gas blown out of the air inlet channel 8 can clean the eye mold 9.

[0035] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
