Description
Technical Field
[0001] The utility model relates to the technical field of guqin production, in particular to a lacquer pushing device for guqin production. Background Art
[0002] The body of a guqin is usually made of high-quality woods such as paulownia or fir. Although these woods have excellent sound quality, they are easily affected by the environment and become deformed or damaged by insects. The lacquer pushing process can form a solid lacquer film on the surface of the guqin body, which effectively isolates air and moisture, prevents wood decay and insect damage, and enhances stability. Pushing lacquer can also enhance the stability of the guqin body to a certain extent, so that it can maintain good sound quality and shape in various climatic conditions.
[0003] However, the traditional method of manually applying lacquer to the guqin is highly dependent on the workers' experience. New workers' hands are not steady enough during the operation, which often leads to uneven application of lacquer, thus affecting the lacquer surface effect of the guqin. Utility Model Content

Afterwards, the tension spring will produce a certain tensile deformation when tilting, so that the paint-pushing brush plate can automatically become perpendicular to the surface curvature of the guqin. In addition, when the worker operates the paint-pushing handle to push the paint on the surface of the guqin, since it is done at the horizontal height of the optical axis, the uniformity of the coating on the guqin can be guaranteed to a certain extent when pushing the paint, avoiding the traditional method of manually pushing the paint on the guqin, which is highly dependent on the worker's experience. The new workers' hands are not steady enough during operation, which often leads to uneven paint pushing, thus affecting the paint surface effect of the guqin.

[0025] See also Figure 1-3 The utility model provides a new technical solution: a lacquer pushing device for guqin production, comprising a guqin placement rack 17 and two optical axes 1, a lacquer pushing auxiliary component is provided between the two optical axes 1, and the lacquer pushing auxiliary component is used to assist the lacquer pushing operation of the guqin;
[0026] The paint pushing auxiliary assembly includes an arc plate 4, an arc groove 5, a slider 6, a fixing ring 8, a threaded sleeve 10, a paint pushing handle rod 11, a paint pushing brush plate 12 and a tension spring 13;
[0027] The outer surface of the fixed ring 8 in the paint pushing auxiliary component is fixedly connected to two rotating support rods 9, and the opposite ends of the two rotating support rods 9 are respectively rotatably connected to the corresponding sliders 6, and the upper parts of the two sliders 6 are fixedly connected to tension spring fixing plates 7.
[0028] Furthermore, two arc grooves 5 are respectively opened on the outer surface of the corresponding arc plate 4, and the two sliders 6 are respectively slidably connected to the inner walls of the corresponding arc grooves 5. The arc grooves 5 are adapted to the surface curvature of the corresponding model of guqin.
[0029] Furthermore, both ends of the two curved plates 4 are fixedly connected with a clamping block 14, the outer surfaces of the two optical axes 1 are slidably connected with a sliding sleeve 2, and both ends of the outer surface of the sliding sleeve 2 are provided with mounting grooves 3 adapted to the clamping block 14, and the clamping blocks 14 are respectively clamped with the corresponding mounting grooves 3.
[0030] Furthermore, a paint box 15 for dipping paint is fixedly installed on the outer surface of the sliding sleeve 2 on one side, and optical axis fixing frames 16 are fixedly connected to both ends of the optical axis 1, and the two optical axis fixing frames 16 are fixedly connected to the guqin placement frame 17.
[0031] Furthermore, the threaded sleeve 10 is threadedly connected in the fixing ring 8 , the paint pushing handle rod 11 is rotatably connected in the threaded sleeve 10 , and the paint pushing brush plate 12 is fixedly connected to the lower end of the paint pushing handle rod 11 .
[0032] Furthermore, two tension springs 13 are fixedly connected between the corresponding tension spring fixing plates 7 and the fixing rings 8, and the tension springs 13 can make the paint brush pushing plate 12 automatically perpendicular to the surface curvature of the guqin.
[0033] Furthermore, when in use, the guqin that needs to be varnished is placed on the guqin placement rack 17, and the surface level of the guqin is adjusted to a level matching the optical axis 1 by using workpieces such as spacers and blocks, and then the varnish is poured into the varnish storage box 15, and the varnish pushing handle rod 11 is manually controlled to drive the two sliders 6 to slide above the varnish storage box 15, so that the varnish pushing brush plate 12 can enter the varnish storage box 15 to dip a part of the varnish liquid, and then the guqin surface is manually varnished.
[0034] Furthermore, the tension spring 13 is provided so that when the paint is pushed to the corner or edge position and the paint brush plate 12 needs to be tilted or turned, the tilting and turning can be completed manually. Afterwards, the tension spring 13 will produce a certain tensile deformation when tilting, so that the paint brush plate 12 can automatically be perpendicular to the surface curvature of the guqin. And when the worker operates the paint pushing handle rod 11 to push paint on the surface of the guqin, since it is done at the horizontal height of the optical axis 1, the uniformity of the coating of the guqin can be guaranteed to a certain extent when the paint is pushed, avoiding the traditional method of manually pushing paint on the guqin, which is highly dependent on the worker's experience. The new workers' hands are not stable enough during operation, which often leads to uneven paint pushing, thus affecting the paint surface effect of the guqin.
[0035] Furthermore, by setting up the installation groove 3 and the block 14, as well as the arc groove 5 that is adapted to the surface curvature of the corresponding model of guqin, it is possible to more conveniently replace the arc groove 5 that is adapted to the corresponding model of guqin when it is necessary to push paint on the surface of a different model of guqin.

[0037] Working principle: When in use, place the guqin that needs to be painted on the guqin placement rack 17, adjust the surface level of the guqin to a level matching the optical axis 1 through workpieces such as gaskets and blocks, and then pour the polishing paint into the paint storage box 15. By manually controlling the paint pushing handle rod 11, the paint pushing handle rod 11 drives the two sliders 6 to slide above the paint storage box 15, so that the paint pushing brush plate 12 can enter the paint storage box 15 to dip a part of the paint liquid, and then manually apply paint to the surface of the guqin.
[0038] The tension spring 13 is set up so that when the paint is pushed to the corner or edge position and the paint brush plate 12 needs to be tilted or turned, the tilting and turning can be completed manually. Afterwards, the tension spring 13 will produce a certain tensile deformation when tilting, so that the paint brush plate 12 can automatically be perpendicular to the surface curvature of the guqin. When the worker operates the paint pushing handle rod 11 to push paint on the surface of the guqin, since it is done at the horizontal height of the optical axis 1, the uniformity of the coating of the guqin can be guaranteed to a certain extent when the paint is pushed, avoiding the traditional method of manually pushing paint on the guqin, which is highly dependent on the worker's experience. The new workers' hands are not stable enough during operation, which often leads to uneven paint pushing, thus affecting the paint surface effect of the guqin.
[0039] By setting up the mounting groove 3 and the clamping block 14, as well as the arc groove 5 adapted to the surface curvature of the corresponding model of guqin, it is possible to more conveniently replace the arc groove 5 adapted to the corresponding model of guqin when it is necessary to push paint on the surface of a different model of guqin. This improves the applicability of the device to pushing paint on different models of guqin to a certain extent.
[0040] By setting up the threaded sleeve 10, when the height position of the paint brush plate 12 needs to be adjusted, the threaded sleeve 10 can be manually rotated, and the rotating threaded sleeve 10 can move up and down in the fixed ring 8, thereby effectively ensuring the fit between the paint brush plate 12 and the surface of the guqin and the uniformity of the paint pushing, thereby further improving the efficiency of guqin paint pushing.
