Description

technical field

[0001] The invention relates to the technical field of electronic piano parts, in particular to a PVC electronic piano bracket profile. Background technique

[0002] In the field of electronic pianos, many of them use solid wood brackets as their accessories, but as the requirements for energy conservation and environmental protection become higher and higher, the cost of solid wood is also getting higher and higher, and the weight of the brackets made of solid wood is relatively high. The installation of various spare parts is also relatively complicated, which is not conducive to the overall manufacturing cost control requirements and installation requirements of the electronic piano. Contents of the invention

[0003] The object of the present invention is to provide a steel wire automatic winding device with a simple structure and capable of automatically winding the steel wire to solve the above-mentioned problems of the steel wire placement and proces...
