Piano automatic chord wrapping machine

Abstract

The invention discloses an automatic string winder of a piano, which comprises a bedframe, a headstock for fixing one end of a string wire, a tailstock for fixing the other end of the string wire. The head stock and the tailstock are arranged on both ends of the bedframe. The bedframe is provided with a mobile worktable. The mobile worktable is arranged between the headstock and the tailstock. The bedframe and the mobile worktable are provided with tightener mechanisms to lead copper wires. The automatic string winder of the piano can wind copper wires evenly on a string wire so that the copper wires are not loose or overlapped. Copper wires are led through the tightener mechanisms. The pull force of the copper wires is stable. The tightness of the copper wires wound on the string wire is uniform. The ends of the copper wires on all of the finished string wires are the same in size, and the length of the copper wires is the same. The automatic string winder of the piano is stopped automatically, and the string is broken automatically, thus improving the working efficiency. One operator can control three automatic string winders with high work efficiency and low labor intensity. A green hand can be familiar with the skill to wind string easily.

Description

technical field [0001] The invention relates to piano string winding technology, in particular to an automatic piano string winding machine. Background technique [0002] Existing piano winding machine is that the machine drives the steel string to rotate, and the copper wire is manually pulled to move along the steel string, so that the copper wire is wound on the steel string. Such a piano winding machine has the following disadvantages: 1. Manual use Pulling the copper wire tightly by hand to move cannot ensure that the copper wire is evenly wound on the steel string, or loose or overlapped; 2. The pulling force of the manual pulling of the copper wire is unstable, resulting in inconsistent tightness of the copper wire wound on the steel string; 3. Artificial Controlling the size of the end of the copper wire wound on the steel string cannot guarantee that the length of the copper wire on each finished steel string is exactly the same; 4. After the winding is completed, t...

Artificial Controlling the size of the end of the copper wire wound on the steel string cannot guarantee that the length of the copper wire on each finished steel string is exactly the same; 4. After the winding is completed, the leg needs to control the stop switch to stop, and then manually control the string breaking mechanism Cutting steel strings has low processing efficiency; 5. One person controls a piano string winding machine, which has low work efficiency and high labor intensity; 6. For a novice worker, it is difficult to master the skill of winding strings
