The automatic wire feeder is an automatic wire feeder which continuously and stably feeds out welding wires according to set parameters (such as wire feeding speed, wire feeding frequency and the like) under the control of terminal equipment. The driving part (comprising a motor, a wire feeding wheel and a pinch roller) in the automatic wire feeder performs wire feeding driving under the control of the terminal equipment, and feeds welding wires into welding equipment (such as a welding gun, a welding machine and the like) from a wire outlet.

Fig. 1(a) -1 (c) provide schematic structural views of a wire feeder. The wire feeder includes: the wire feeder comprises a wire feeder main body 20 and a motor 30, wherein the wire feeder main body 20 comprises a wire inlet hole 201, a wire inlet pipe 202, a wire feeding wheel 203, a pressing wheel 204, a driven wheel 211, a bracket 205, a wire guide pipe 206, a wire outlet pipe 37 and a wire outlet hole 208. The wire inlet pipe 202 is inserted into the wire inlet hole 201, and one end of the wire outlet pipe 207 is inserted into the wire outlet hole 208 and connected with the welding equipment. The pressing wheel 204 is used for pressing the welding wire into the wire feeding groove of the wire feeding wheel 203 in the wire feeding process, so that the friction force between the welding wire and the wire feeding wheel 203 is increased, and the welding wire can be smoothly fed out of the wire feeder main body 20. The pressing wheel 204 and the wire feeding groove on the wire feeding wheel 203 form a first wire guiding channel 210. The wire feeder further includes a wire feeding tray on which a welding wire is mounted, the welding wire being inserted into a wire feeding passage in the wire feeder main body 20 through the wire inlet hole 201. The motor 30 is used for driving the wire feeding disc and the wire feeding wheel 203 to rotate.

Specifically, the wire feeding wheel 203 includes at least one. Illustratively, as shown in fig. 1(a), the wire feeding wheel 203 includes a first wire feeding wheel 2031 and a second wire feeding wheel 2032, the first wire feeding wheel 2031 and the second wire feeding wheel 2032 are respectively provided with wire feeding grooves, and the driven wheel 211 is respectively engaged with the first wire feeding wheel 2031 and the second wire feeding wheel 2032. The first wire feeding wheel 2031 is a driving wheel, the motor 30 can drive the first wire feeding wheel 2031 to rotate, and the first wire feeding wheel drives the driven wheel 211 to rotate, so as to drive the second wire feeding wheel 2032 to rotate.

The number of the pressing wheels 204 is the same as that of the wire feeding wheels 203. For example, as shown in FIG. 1(a), puck 204 includes puck 204 that includes first puck 2041 and second puck 2042. The first pressing wheel 2041 is engaged with the first wire feeding wheel 2031, and the wire feeding grooves of the first pressing wheel 2041 and the first wire feeding wheel 2031 form a wire guiding channel. The second pressing wheel 2042 is engaged with the second wire feeding wheel 2032, and the wire feeding grooves of the second pressing wheel 2042 and the second wire feeding wheel 2032 form a wire guiding channel. The first pressing wheel 2041 and the second pressing wheel 2042 are respectively fixed on a pressing rod 209, and the pressing rod 209 is hinged with the wire feeder main body 20.

The holder 205 is provided with a guide hole 2051, the holder 205 is disposed between the first thread feeding roller 2031 and the second thread feeding roller 2032, and the guide wire tube 206 is inserted into the guide hole 2051 and the guide wire tube 206 is fixed to the holder 205 by a fixing means.

In the wire feeder, the wire inlet 201, the wire inlet pipe 202, the first wire guiding channel 210, the wire guiding pipe 206, the wire outlet pipe 207 and the wire outlet 208 form a wire feeding channel. The wire feeding channel comprises five sections, and a certain distance is reserved between every two sections, namely the wire feeding channel is provided with a plurality of break points. Although the welding wire has certain hardness, when the distance between the break points is too large, the welding wire cannot be accurately conveyed from the upper section to the lower section of the wire feeding channel only by the hardness of the welding wire, so that the welding wire is bent in the wire feeding process, and the wire clamping phenomenon occurs.

At present, in order to avoid wire jamming during wire feeding, an operator generally needs to insert a welding wire into a channel between a wire feeding groove of a first wire feeding wheel 2031 and a first pressing wheel 2041 through a wire feeding tube 202, and then poke the welding wire with a hand to insert the welding wire into a channel between a wire feeding groove of a second wire feeding wheel 2032 and a second pressing wheel 2042 through a wire guiding tube 206, and then insert the welding wire into a wire discharging tube 207. After the welding wire is inserted into the wire feeding tube 202, the wire feeding groove of the first wire feeding wheel 2031, the wire guiding tube 206, the wire feeding groove of the second wire feeding wheel 2032 and the wire discharging tube 207 in sequence, the motor 30 is started again to drive the wire feeding disc and the wire feeding wheel 203 to rotate, so that the welding wire can be stably conveyed into the welding equipment. The operator is easily scratched or pinched by the wire feed wheel 203 during the process of pressing the welding wire with fingers.

In order to solve the above technical problem, the present application provides an auxiliary guiding device of a wire feeder, which is provided with a second wire guiding channel 106. When the device is installed on the wire feeder body 20, the second wire guide channel 106 communicates with the first wire guide channel 210 on the wire feeder body 20, thereby forming a complete and breakpoint-free wire feed channel. During the wire feeding process, the welding wire can be accurately conveyed to the welding equipment through the wire feeding channel without manual pressing of an operator.

The wire feeder auxiliary guide 10 provided herein will be described in detail with reference to the accompanying drawings.

Fig. 2(a) -2 (d) illustrate a wire feeder auxiliary guide 10 mounted to a wire feeder body 20 according to the present disclosure. As shown in fig. 1(a) -1 (c), the wire feeder main body 20 includes a wire inlet 201, a wire feeding roller 203 having a wire feeding groove, a pressing roller 204, and a wire outlet 208. When the pressing wheel 204 is engaged with the wire feeding wheel 203, a first wire guide channel 210 is formed between the pressing wheel 204 and the wire feeding groove. As shown in fig. 2(a) -2 (d), the wire feeder auxiliary guide 10 is provided with a second wire guide channel 106 and a hole 107. The auxiliary guide device 10 of the wire feeder is arranged between the pressing wheel 204 and the wire feeding wheel 203, the pressing wheel 204 passes through the hole 107 to be meshed with the wire feeding wheel 203, and the wire inlet hole 201, the second wire guide channel 106, the first wire guide channel 210 and the wire outlet hole 208 are communicated adjacently.

In one embodiment, the second guidewire channel 106 and the first guidewire channel 210 form a straight channel.

The auxiliary guide device 10 of the wire feeder provided by the present application is disposed between the pressing wheel 204 and the wire feeding wheel 203, the pressing wheel 204 is engaged with the wire feeding wheel 203 through the hole 107, the second wire guiding channel 106 is adjacently communicated with the first wire guiding channel 210, and two ends of the second wire guiding channel 106 are aligned with the wire inlet 201 and the wire outlet 208 on the wire feeder main body 20, respectively. In order to avoid friction between the wire feeding wheel 203 and the pressing wheel 204 and the second wire guide channel 106 when rotating, a certain distance is formed between the second wire guide channel 106 and the first wire guide channel 210, but the distance is small and can be ignored, because the welding wire has certain hardness, the distance does not influence the autonomous transmission of the welding wire from the second wire guide channel 106 to the first wire guide channel 210, and the wire clamping phenomenon does not occur. The wire inlet 201, the second wire guide channel 106, the first wire guide channel 210 and the wire outlet 208 may thus form a complete and breakpoint-free wire feed channel, so that the auxiliary wire feeder may quickly and accurately deliver welding wire from the wire feed channel to the welding apparatus without requiring an operator to manually pass the welding wire through the wire feed channel.

In one embodiment, at least one wire feeding wheel 203 is disposed on the wire feeder body 1, at least one hole 107 is disposed on the wire feeder auxiliary guide device 10, and the number of the holes 107 is the same as that of the wire feeding wheels 203.

In one possible implementation, the wire feeder auxiliary guide 10 is further provided with a first slot 108. The wire feeder body includes a bracket 205, and a guide hole 2051 is provided on the bracket 205. When the wire feeder auxiliary guide 10 is mounted on the wire feeder body 20, the bracket 205 is inserted into the first slot 108, and the guide hole 2051 communicates with the second wire guide channel 106.

Preferably, the size of the first slot 108 may match the size of the cradle 205 such that the cradle 205 fits snugly into the first slot 108, thereby allowing the wire feeder auxiliary guide 10 to be secured to the wire feeder body 20. The guide hole 2051 is formed in the bracket 205, and the guide hole 2051 is communicated with the second guide wire channel 106, so that the wire inlet hole 201, the second guide wire channel 106, the first guide wire channel 210, the guide hole 2051 and the wire outlet hole 208 can form a complete wire feeding channel without break points.

It is to be appreciated that, in one aspect, the wire feeder auxiliary guide 10 described herein may be a wire feeder spool having a second wire guide channel 106 and a bore 107, and the wire feeder spool may be cylindrical, square, or any other shape. In this case, the auxiliary wire feeder guide 10 may be secured to the wire feeder body 20 via the first slot 108, or may be secured to the wire feeder body 20 via other securing means.

On the other hand, the auxiliary guiding device 10 of the wire feeder described in the present application may also be a device including a side plate as shown in fig. 2(a) -2 (d).

The at least one first insertion hole 1031 corresponds to a fixed shaft of at least one wire feed wheel of the plurality of wire feed wheels 203, respectively, and the wire feeder auxiliary guide 10 is fixed to the fixed shaft of the wire feed wheel 203 through the first insertion hole 1031 by a fixing means.

Generally, the wire feeding wheel 203 is fixed to a fixed shaft by a fixing device (e.g., a screw, etc.), a first insertion hole 1031 is formed in the auxiliary guiding device 10 at a position corresponding to the fixed shaft, and when the auxiliary guiding device 10 is to be mounted to the main body 20 of the wire feeder, the fixing device is detached and inserted into the first insertion hole 1031, so that the auxiliary guiding device 10 can be fixed to the fixed shaft without any other fixing device.

In another possible implementation, the wire feeder auxiliary guide 10 is provided with a second receptacle 1032, and the wire feeder body 20 further includes the driven wheel 211. The second receptacle 1032 corresponds to a fixed axis of the driven wheel 211 when the auxiliary wire feeder guide 10 is mounted on the wire feeder body 20, and fixes the auxiliary wire feeder guide 10 to the fixed axis of the driven wheel 211 by a fixing means.

When the wire feeder main body 20 is provided with a plurality of wire feeding rollers 2031, it is necessary to drive a part of the wire feeding rollers 2031 to rotate by the driven wheel 211.
