In BC batteries (back-contact batteries, which can be combined with various circuits), the wire lead-out structure is complex, the number of spools is fixed, and the mounting shaft and output structure occupy a significant amount of mounting space. When heavy spools are rotating, slippage is common, and the wire output can be excessively long. Utility Model Content

[0003] One objective of this utility model is to provide a welding wire feeding structure in which the output structure of the wire spool forms a modular block, and the corresponding number is installed according to the requirements. Under the action of the ejector pin, the heavy wire spool is effectively restricted to stop rotating in time, so as to keep the welding wire in a straight state.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A welding wire feeding structure includes a welding wire feed frame, a welding wire feed module, and an upper wire feeding wheel. The upper wire feeding wheel is located at the lower end of the welding wire feed frame. The welding wire feed frame is provided with a plurality of module mounting holes. The welding wire feed module is fixed in the module mounting holes. A module mounting plate is provided on the welding wire feed module. A welding wire hanging cylinder shaft is rotatably mounted on the module mounting plate. A wire spool is sleeved on the welding wire hanging cylinder shaft. A connecting plate is fixed to the inner end of the welding wire hanging cylinder shaft. A pin is locked on the connecting plate. An emergency stop hole is provided on the side of the wire spool. The end of the pin is inserted into the emergency stop hole. A locking nut is installed on the outer end of the welding wire hanging cylinder shaft.

[0006] As a preferred technical solution, the edge of the module mounting plate is provided with a module locking hole, and the welding wire lead module is locked onto the module mounting hole position by a screw on the module locking hole.

[0007] As a preferred technical solution, a cylindrical motor is installed at the lower end of the module mounting plate, and cylindrical pulleys are installed at both the drive end of the cylindrical motor and the end of the welding wire hanging cylindrical shaft, with a cylindrical belt connecting the cylindrical pulleys for transmission.

[0008] As a preferred technical solution, the connecting plate is provided with an adjustment groove in the horizontal direction, and a connecting pin plate is locked on the adjustment groove. The pin is locked on the connecting pin plate by a nut.

[0009] As a preferred technical solution, the wire feeder is provided with several auxiliary wire shafts.

[0010] As a preferred technical solution, the lower end of the welding wire outlet frame is equipped with a front and rear conductor main seat, and a plurality of front and rear conductor rotating shafts are distributed laterally on the front and rear conductor main seat. The front and rear conductor main shafts are fixed in the mounting groove of the front and rear conductor main seat.

[0011] The beneficial effects of this utility model are as follows: It provides a welding wire feeding structure that enables modular installation, quick and convenient replacement, reduces the installation lock in front of the wire output frame, and stops the wire spool in time as the welding wire hanging spool shaft stops by inserting a pin into the emergency stop hole, preventing the heavy wire spool from slipping when outputting welding wire, and making the conveying smoother.

The cover plate can be directly covered on the module mounting hole 4 that is not in use. The module mounting plate 5 is assembled as a whole module together with the other components above it on the module mounting hole 4. After the spool 7 is put on the welding wire hanging spool shaft 6, the locking nut 10 is used to lock the spool 7 on the outside. When the heavy spool 7 needs to stop rotating, the spool shaft motor 12 stops the welding wire hanging spool shaft 6 in time.
