Manufacturing equipment and manufacturing method of piano climbing belt

Abstract

The invention discloses manufacturing equipment of a piano climbing belt. The equipment comprises a climbing belt head sticking machine, which comprises a driving device, a winding wheel connected tothe driving device, a rope guide mechanism connected to the driving device, and a plurality of climbing belt head sticking dies circumferentially arranged on the winding wheel. Each climbing belt headsticking die is equipped with a positioning groove and a plurality of rope grooves which are communicated with the positioning groove and are arranged in the length direction, the positioning groovesare configured to position a leather strip used for manufacturing a climbing belt head, the rope grooves are configured to position a rope used for manufacturing a climbing belt rope, and the drivingdevice is used for driving the winding wheel to rotate and enabling the rope to be wound on the leather strip along the rope grooves under the action of the rope guide mechanism and the winding wheelto form a blank with a plurality of blank units. The equipment also includes a climbing belt head punching machine, which comprises a punching die, and the punching die is provided with a punching structure matched with the shape of a climbing belt head so as to punch and slit each blank unit to form a plurality of climbing belts. According to the invention, the manufactured climbing belts are high in quality, stable in quality and low in labor cost, therefore batch production can be achieved.

Description

technical field [0001] The invention relates to the field of musical instrument manufacturing, in particular to a manufacturing device and a manufacturing method of a piano strap. Background technique [0002] The climbing belt is a part of the piano, which usually includes a climbing belt head and a belt rope connected to the climbing belt head. The belt climbing head is provided with a belt hole, and the belt hole is a through hole, which can be hung on the belt hook. Through the climbing belt, the hammer can be pushed back to its original position and the fast combo speed of the hammer can be ensured. The climbing rope is usually bonded to the climbing head by means of glue. [0003] The existing climbing belt bonding method is purely handmade, and the climbing belt head is supplied by the material supplier, and the climbing belt rope is cut into a standard length. When bonding, the worker first applies white glue to the climbing belt head. Since the glue is applied to ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned production process is purely handmade, and the production quality of each worker is different. There are uneven glue application, weak adhesion, different bonding positions of the climbing rope, differences in the size of the puncture holes, asymmetrical climbing ropes, and rope ends. Dispersion and other issues

The quality inspection of the workpiece has a large workload and a large amount of material loss. The production method and quality problems of the workpiece affect the assembly quality of the piano

Manual operation can only be made in a single distribution. Due to the large number of workpieces, it takes up a lot of space and manpower, making it impossible to form mass production, which increases the operating cost of the enterprise
