In this embodiment, one side of the base 1 is further provided with an outwardly protruding engaging lug 15, and the engaging lug 15 is provided with a first mounting hole 151 and a second mounting hole 152. The base 1 is connected to a main shaft of a soldering apparatus through a first mounting hole 151 and a second mounting hole 152 of the connection lug 15. Specifically, be fixed with the connection piece on tin soldering equipment's the main shaft, be equipped with the connecting hole that corresponds with first mounting hole 151 position on the connection piece and correspond the arc connecting hole that sets up with second installation position, a rotation connecting piece passes first mounting hole 151 and connecting hole and will connect otic placode 15 on the connection piece, another swing joint wears to establish between second mounting hole 152 and the arc connecting hole, can adjust the angle between base 1 and the tin soldering equipment main shaft, thereby realize sending orbital arc setting of tin, reduce and send the tin resistance.

In summary, in the tin wire conveying mechanism provided in the embodiment of the present invention, in the process of conveying the tin wire, the tin wire sequentially passes through the floating tin conveying tube 2, the guide wheel 6, the third guide tube 56, the tin conveying driving assembly 4, the first guide tube 52, the second guide tube 53 and the tin outlet guide tube 32, the tin conveying driving assembly 4 drives the driving wheel 42 to rotate through the motor, the driving wheel 42 drives the driven wheel 43 to rotate, the driving wheel 42 and the driven wheel 43 generate friction force to the tin wire therebetween, and the friction force is used as power for conveying the tin wire; set up third stand pipe 56 on sending tin drive assembly 4 fore-and-aft tin silk delivery track, first stand pipe 52 and second stand pipe 53, third stand pipe 56, first stand pipe 52 and second stand pipe 53 have with action wheel 42 and follow the public tangent line syntropy extension's of driving wheel 43 guide passageway, guide passageway plays the effect of guide to the direction of delivery of tin silk, the tin silk is linear motion along action wheel 42 and the public tangent line direction of following driving wheel 43 around sending tin drive assembly 4, avoided taking place to buckle and cause the cracked problem of tin silk because of tin silk direction of delivery, can realize the stable transport of the tin silk that the diameter is less than 0.6mm, moreover, the steam generator is simple in structure, the job stabilization nature is good.
