Tinning guide wheel

Abstract

The invention discloses a tinning guide wheel. The tinning guide wheel comprises a fixed plate, a fixed wheel, a first rotating wheel, a second rotating wheel and three bearings. The fixed plate comprises a hole. The three bearings penetrate through the circle center of the first rotating wheel, the circle center of the second rotating wheel and the circle center of the fixed wheel correspondingly. The circle center of the first rotating wheel is flush with the circle center of the fixed wheel, and the radius of the first rotating wheel is equal to the radius of the fixed wheel. The distance of the straight line where the circle center of the first rotating wheel and the circle center of the fixed wheel are located to the circle center of the second rotating wheel is smaller than the sum of the radius of the first rotating wheel and the radius of the second rotating wheel. According to the tinning guide wheel provided by the invention, compared with a traditional guide wheel, the second rotating wheel is additionally arranged, and a tensioning effect is achieved; in order to save materials, the radius of the second rotating wheel is smaller than that of the first rotating wheel; and meanwhile, the tinning guide wheel is practical, durable, easy to manufacture and produce and not prone to being damaged.

Description

technical field [0001] The invention relates to the field of tinning machines, in particular to the field of tinning guide wheels in the tinning machine. Background technique [0002] In order to achieve the purpose of anti-corrosion, improving electrical conductivity and welding performance, tin plating is chosen on products such as copper bars, aluminum bars, transformers, and electrical terminal blocks. Generally, tinning guide wheels are installed in the tinning pool. The role of the tinning guide wheel is to transport copper wires and other items, so that they run along the track of the guide wheel and enter the tinning pool for tinning. The overall manufacturing material of the tinned guide wheel is a metal material, and the melting point of the material is greater than that of tin. [0003] But the existing tin-plated guide wheel generally all is made up of two circular wheels and a fixed plate, and two circular wheels are fixed on the fixed plate, and one is fixed ...

AI Technical Summary

Problems solved by technology

[0003] But the existing tin-plated guide wheel generally all is made up of two circular wheels and a fixed plate, and two circular wheels are fixed on the fixed plate, and one is fixed non-rotatable circular wheel, and another is rotatable circular wheel, and fixed plate there is a hole

However, when items such as copper wires enter the tinning bath along the tinning guide wheel, the tinning effect will be poor due to untensioned copper wires and other items, which is a serious deficiency.
