Description

Technical Field

[0001] The utility model relates to the field of photovoltaic welding ribbon production equipment, in particular to a double-headed wire rewinding frame for photovoltaic welding ribbons. Background Art

[0002] The last step in the production process of photovoltaic welding ribbon is to reel the welding ribbon. Since the surface of the welding ribbon is tinned, the winding arrangement of the welding ribbon on the reel during reeling is required to be high, and there must be no misalignment or other problems. Otherwise, friction between the welding ribbons is likely to cause the coating to fall off, affecting the use of the welding ribbon. Therefore, sometimes a special wire reeling machine is needed to reel the wire, remove the problems during reeling and then rewind it. The commonly used wire reeling machine is passively rotated during use. Therefore, when the on-site personnel temporarily stop during the reeling process because they find a problem with the photovoltaic welding ribbon, the wire reeling reel often continues to rotate due to inertia, resulting in the disappearance of the wire tension. In order to solve this problem, our company has optimized the traditional wire reeling machine and produced the special wire reeling rack described in CN220148777U. However, with the development of the company and the increase in output, the company's demand for the wire reeling mechanism has increased, but the space available is limited. Therefore, it is necessary to transform the existing device to improve the level of automation in the workshop on the one hand, and on the other hand, to improve the efficiency of the wire reeling mechanism and make full use of the existing space.

[0021] The upper tension wheel mounting plate 8 is also equipped with an upper tension regulating cylinder 25 and an upper tension regulating valve 27.
