Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of guitar musical instruments, in particular to a guitar scale line production and adjustment device. Background Art
[0002] Guitar is a plucked instrument that produces sound by plucking the guitar strings with fingers to generate vibrations. The guitar mainly produces sound through the guitar strings, which are the scale wires. The scale wires are an important part of the guitar. Different scale wires are made of a variety of different elastic materials and can produce different styles of sounds. The scale wires need to be gradually drawn and formed by multiple devices during the production process. In order to make the scale wires more uniform in thickness after production, it is necessary to set an adjustment device between multiple drawing production equipment. The adjustment device clamps and fixes one end of the scale wire, and sets different tensions through the wire output speeds between different drawing equipment, so that the drawn scale wire is evenly stressed during output, which can effectively balance the speed and tension differences between the drawing equipment to prevent the scale wires from being produced with different thicknesses and affecting the sound effect.
[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: although the existing adjustment device can balance the speed and tension difference between the wire drawing equipment by setting different tensions, in order to prevent the scale wire from sliding when pulling, a strong pressure is applied to the end of the scale wire to clamp and fix the end of the scale wire, and then the scale wire is reeled and pulled. After clamping and fixing, it is easy to produce high-pressure indentations on the surface of the relatively soft scale wire, so that the end part of each roll of the scale wire produced needs to be cut off when used, which wastes materials and increases the production cost in disguise. Utility Model Content

[0007] A further improvement is that a guide roller is also provided on the top surface of the fixed platform between the flattening roller and the tension adjustment frame.

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.
[0021] See also Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: a guitar scale line production and adjustment device, including a fixed platform 1 and an introduction frame 2 arranged on the top surface of the fixed platform 1, a power motor 4 is arranged in the fixed platform 1, and a tension adjustment frame 3 connected to the power motor 4 through a belt is also arranged on the top surface of the fixed platform 1, the tension adjustment frame 3 includes a connecting bracket 31 arranged on the top surface of the fixed platform 1 and a power wheel 32 movably engaged in the connecting bracket 31 and connected to the power motor 4 through a belt, a pulling drum 34 is arranged at the end of the power wheel 32, a contraction groove 35 is arranged on the outer wall of the pulling drum 34, a contraction cylinder 36 is arranged in the contraction groove 35, a flexible contraction device 38 is connected to the end of the contraction cylinder 36, the flexible contraction device 38 includes an inner pressure arc plate 41 fixedly connected to the end of the contraction cylinder 36 and a plurality of suction and pressure torsion springs 42 embedded in the inner pressure arc plate 41, and this embodiment is provided with three, after the scale line is pulled into the pulling drum 34, the scale line is flexibly squeezed and fixed by the contraction cylinder 36 and the flexible contraction device 38. When in use, the scale wire is pulled into the tension adjustment frame 3 through the introduction frame 2, and the end of the scale wire is squeezed and fixed by the flexible contraction device 38 on the pull reel 34 in cooperation with the contraction cylinder 36. The contraction cylinder 36 generates contraction pressure and then applies pressure to the inner pressure arc plate 41, so that the inner pressure arc plate 41 contacts the outer wall of the pulled scale wire. When the pressure is too large, the inner pressure arc plate 41 is twisted under the action of the suction and pressure torsion spring 42, and then the pressure is converted into the elastic force generated by the twisting of the suction and pressure torsion spring 42, thereby To reduce the extrusion on the surface of the scale wire, and at the same time, in conjunction with the suction pressure torsion spring 42, the middle section of the inner pressure arc plate 41 can produce an angle change, so that the inner wall of the inner pressure arc plate 41 can fit the surface of the scale wire with a larger area, thereby dispersing the pressure, making the unit pressure on the surface of the scale wire smaller, avoiding the generation of indentations, and then the power wheel 32 can receive the power of the power motor 4 to generate tension, and different wire drawing equipment can be used to make the power motor 4 generate different tensions, and then the produced scale wire can be pulled in and rolled up through the pulling reel 34;
[0022] The top surface of the fixed platform 1 is located between the introduction frame 2 and the tension adjustment frame 3 and is also provided with a flattening roller 5, which is conducive to straightening the introduced scale line to avoid skewing when the noise is pulled into the tension adjustment frame 3;
[0023] The top surface of the fixing table 1 is located between the flattening roller 5 and the tension adjustment frame 3 and is also provided with a guide roller 6, which is conducive to the second straightening of the scale line and at the same time allows it to be introduced into the tension adjustment frame 3 at a more stable angle;
[0024] The two sides of the pull drum 34 are detachably provided with anti-falling guardrails 33, which are helpful to prevent the scale wire from falling out of the pull drum 34, and can be removed when taking the wire without hindering the wire taking;
[0025] The inner wall of the inner pressure arc plate 41 is also provided with a plurality of damping blocks 43. In this embodiment, four damping blocks 43 are hollow elliptical spherical structures made of elastic material, which are beneficial to improving the buffering effect when the inner pressure arc plate 41 contacts the scale line, and further avoiding the generation of indentations on the surface of the scale line;
[0026] An anti-detachment hook 44 is also embedded in the inner wall of the end of the inner pressure arc plate 41. The anti-detachment hook 44 is an arc-shaped hook-shaped thin plate structure made of elastic material, which is conducive to holding the scale line from the end. At the same time, it can shrink and deform when the pressure is too large, thereby preventing the scale line from sliding while maintaining the anti-indentation effect.
[0027] The working principle of the utility model is as follows: when in use, the scale wire is pulled into the tension adjustment frame 3 through the introduction frame 2, and the end of the scale wire is squeezed and fixed by the flexible contraction device 38 on the pull drum 34 in cooperation with the contraction cylinder 36. The contraction cylinder 36 generates contraction pressure and then applies pressure to the inner pressure arc plate 41, so that the inner pressure arc plate 41 contacts the outer wall of the pulled scale wire. When the pressure is too large, the inner pressure arc plate 41 is twisted under the action of the suction pressure torsion spring 42, and then the pressure is converted into the torsion of the suction pressure torsion spring 42. Elastic force can reduce the extrusion on the surface of the scale wire, and at the same time, the suction and pressure torsion spring 42 can make the middle section of the inner pressure arc plate 41 produce an angle change, so that the inner wall of the inner pressure arc plate 41 can fit the surface of the scale wire with a larger area, thereby dispersing the pressure and making the unit pressure on the surface of the scale wire smaller to avoid indentation. Then, the power wheel 32 can receive the power of the power motor 4 to generate tension, and different wire drawing equipment can be used to make the power motor 4 generate different tensions, and then the produced scale wire can be pulled in and rolled up through the pulling reel 34.
