Description

Technical Field

[0001] The present invention relates to the technical field of musical instrument processing, and specifically to a processing device for a violin panel. Background Art

[0002] A violin is a stringed instrument with four strings. It generates vibrations by the friction between the strings and the bow, and then conducts the vibrations to the back plate through the sound post inside the resonance box (the body of the violin). The resonance generated by these parts produces a harmonious and bright sound. The panel of the violin is one of its most important components, which has a crucial impact on both the tone color and the appearance. The panel is usually made of spruce wood, which has delicate texture, soft color, and high resonance, and can improve the performance of the player. The production of the panel includes material selection, board splicing, scraping, the production of sound holes and sound beams, and the assembly of the violin. Board splicing is to cut a piece of wood in the middle and then splice it in half, ensuring that the wood grain is symmetrical to improve the sound quality. When splicing the boards, glue is evenly applied to the butt joint surface of the two pieces of wood, and after docking, it is fixed until the glue is completely solidified. The production of the violin panel still stays at the manual technical level, resulting in inaccurate positioning of the wood and easy deviation during docking. Moreover, since the panel is made of spruce wood, which has high humidity and internal stress in the wood, when the board splicing is completed at room temperature, it is impossible to further improve the stability of the panel and the sound quality. Therefore, it is necessary to propose a processing device for a violin panel that can accurately splice the boards. Summary of the Invention

The telescopic column is inserted into the inner cavity of the sleeve in a slidable manner along the front-rear direction. The guide groove is opened in the middle of the upper surface of the telescopic column. The number of the limiting sleeves is two, and they are respectively installed at the front ends of the left and right sides of the sleeve. The lifting column is inserted into the inner cavity of the limiting sleeve in a vertically slidable manner. The roller is installed at the inner top of the lifting column in a rotatable manner, and the telescopic column supports the roller.

Specific embodiments

[0025] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0026] Embodiment, as Figure 1 shown, in the embodiment of the present invention, a violin panel processing device includes a heat preservation box 1, four support legs 2 and two split box doors 3. The four support legs 2 are respectively fixedly connected to the four corners of the lower surface of the heat preservation box 1. The two split box doors 3 are respectively installed on the left and right sides of the front of the heat preservation box 1 through hinges. A splicing mechanism 4 is installed at the bottom of the inner cavity of the heat preservation box 1, and a heating mechanism 5 is installed on the right side wall of the heat preservation box 1.

[0027] More specifically, as Figure 2 and Figure 3As shown in the figure, the splicing mechanism 4 includes a support plate 41 installed at the bottom of the inner cavity of the insulation box 1. On the front and rear sides of the upper surface of the support plate 41, slide rails 42 are horizontally installed. On the left and right sides of the outer wall of the slide rail 42, sliding seats 43 are sleeved. At the center position of the lower surface of the support plate 41, a motor 44 is installed. At the output end of the motor 44, a traction rod 45 is installed. At both ends of the traction rod 45, one end of a connecting rod 46 is connected through a pin shaft. The other end of the connecting rod 46 is connected to the lower surface of the sliding seat 43 through a pin shaft. The motor 44 drives the traction rod 45 to rotate clockwise or counterclockwise, so that the connecting rod 46 pulls the two sliding seats 43 to move inward or outward simultaneously. Several limiting components 47 are embedded in the upper surface of the sliding seat 43 from left to right. At the rear end of the upper surface of the sliding seat 43, a positioning component 48 is vertically installed.

[0028] Further, as Figure 4 shown, the limiting component 47 includes an outer cylinder 471 embedded in the upper surface of the sliding seat 43. At the bottom of the inner cavity of the outer cylinder 471, a first guide rod 472 is vertically installed. A limiting column 473 that can slide up and down is sleeved on the outer wall of the first guide rod 472. A first spring 474 is inserted into the inner cavity of the limiting column 473. The elastic force of the first spring 474 pushes the limiting column 473 to rise. In the middle of the right side wall of the limiting column 473, a first inclined block 475 is installed. The first inclined block 475 limits the rise of the limiting column 473. A box body 476 is installed on the right side wall of the outer cylinder 471. At the top of the right inner wall of the box body 476, a second guide rod 477 is horizontally installed. On the left and right sides of the outer wall of the second guide rod 477, a stop rod 478 and a second spring 479 are sleeved respectively. The elastic force of the second spring 479 can push the stop rod 478 to move leftward. By blocking the first inclined block 475 with the stop rod 478, the height of the limiting column 473 can be reduced. Vertically installed on the lower surface of the stop rod 478 is a third guide rod 4710. A second inclined block 4711 that can slide up and down is sleeved on the outer wall of the third guide rod 4710. The left side surfaces of the stop rod 478 and the second inclined block 4711 are both inclined surfaces, and the two inclined surfaces are symmetric up and down. When the limiting column 473 descends, the inclined surface of the first inclined block 475 squeezes the inclined surface of the stop rod 478, causing the stop rod 478 to move rightward along the outer wall of the second guide rod 477. When the limiting column 473 rises, the first inclined block 475 first pushes the second inclined block 4711 to rise until the second inclined block 4711 contacts the stop rod 478. The first inclined block 475 squeezes the inclined surface of the second inclined block 4711, causing the stop rod 478 and the second inclined block 4711 to move rightward, so that the first inclined block 475 moves above the stop rod 478.

[0029] Further, as Figure 5 and Figure 6As shown in the figure, the positioning component 48 includes a vertical column 481 installed at the rear end of the upper surface of the sliding seat 43. A sleeve 482 is installed at the top of the column 481 in the front-rear direction. A telescopic column 483 that can slide back and forth is inserted into the inner cavity of the sleeve 482. A guide groove 484 with an inclined front side is opened in the middle of the upper surface of the telescopic column 483. Limiting sleeves 485 are installed at the front ends of the left and right side walls of the sleeve 482. A lifting column 486 that can slide up and down is inserted into the inner cavity of the limiting sleeve 485. A roller 487 is horizontally installed at the top inside the lifting column 486, and the telescopic column 483 supports the roller 487. When the telescopic column 483 moves forward, the inclined surface of the guide groove 484 causes the roller 487 to descend under the action of gravity. A pressing plate 488 is installed at the bottom end of the lifting column 486. The pressing plate 488 is used to press down the small front panel to position the panel. A rubber pad is bonded to the lower surface of the pressing plate 488. The rubber pad has elasticity to prevent indentations on the surface of the panel.

[0030] Further, as shown in Figure 1 , Figure 7 and Figure 8 the figure, the temperature-rising mechanism 5 includes a distillation box 51 installed obliquely at the top of the right side wall of the heat preservation box 1. A flow channel 52 is opened inside the distillation box 51, and the left end of the flow channel 52 is communicated with the inner cavity of the heat preservation box 1. The flow channel 52 is distributed in a serpentine shape inside the distillation box 51. The right end opening of the flow channel 52 becomes smaller. The flow channel 52 can extend the residence time of the gas in the distillation box 51, and the larger inner diameter of the flow channel 52 can further delay the movement speed of the gas, allowing the gas to have enough time to cool down. The water vapor in the gas liquefies into accumulated water. A water accumulation bucket 54 is screwed to the right end of the lower surface of the distillation box 51. The accumulated water in the flow channel 52 can flow into the water accumulation bucket 54 along the inclined surface. One end of a first air pipe 55 is installed at the right end of the flow channel 52, and the other end of the first air pipe 55 is installed with a hot air blower 56. The gas is heated by the hot air blower 56. The bottom of the hot air blower 56 is connected to the bottom of the right side wall of the heat preservation box 1 through a second air pipe 57 to circulate the hot air in the heat preservation box 1 and provide a high-temperature and dry environment.

[0031] Working principle:

[0032] Step 1: According to the size of the violin panel, press down the limiting column 473 to cause the first inclined block 475 to squeeze the stop lever 478 downward, so that the stop lever 478 moves to the right along the outer wall of the first guide rod 472 under the action of its own inclined surface. When the first inclined block 475 moves to the bottom of the stop lever 478, the second spring 479 pushes the stop lever 478 to the left to limit the upward movement of the first inclined block 475, and the limiting column 473 is retracted into the outer cylinder 471.

[0033] If the limit post 473 is continuously pressed downwards to make the first inclined block 475 push the second inclined block 4711 downwards, the inclined surface of the first inclined block 475 can make the second inclined block 4711 move to the right. When the first inclined block 475 moves to the bottom of the second inclined block 4711, the elastic force of the second spring 479 makes the second inclined block 4711 move to the left, and the limit post 473 is released. The first spring 474 pushes the limit post 473 to rise. At the same time, the first inclined block 475 first pushes the second inclined block 4711 to rise. When the second inclined block 4711 contacts the stop lever 478, the inclined surface of the second inclined block 4711 can make itself move to the right, and the first inclined block 475 disengages from the second inclined block 4711 and the stop lever 478 in sequence, and the limit post 473 extends out of the outer cylinder 471. Therefore, by adjusting the height of the limit post 473, the positioning of violin panels of different sizes is achieved;

[0034] In the second step, after the panel is placed on the sliding seat 43, the telescopic column 483 is pulled forward. The inclined surface of the guide groove 484 allows the roller 487 to descend under its own gravity. The pressing plate 488 can be lowered through the cooperation of the limit sleeve 485 and the lifting column 486. The gravity of the pressing plate 488 presses the panel tightly on the sliding seat 43, completing the positioning of the two spliced panels;

[0035] In the third step, after the glue is applied to the splicing surface of the panel, the traction rod 45 is driven by the motor 44 to rotate clockwise, and the connecting rod 46 pulls the two sliding seats 43 to move inward simultaneously until the two panels contact each other, realizing the precise splicing of the panel;

[0036] In the fourth step, during the splicing process, the suction of the hot air blower 56 allows the gas to enter from the flow channel 52. The heater in the hot air blower 56 heats the gas, and then the hot air is discharged into the insulation box 1 through the second air pipe 57 to increase the temperature in the insulation box 1. When the water vapor in the gas passes through the flow channel 52, the condenser 53 cools the water vapor, and the water vapor liquefies into accumulated water. Due to the inclination of the distillation box 51, the accumulated water flows into the water accumulation bucket 54 to dehumidify the gas, creating a high-temperature and dry environment for the insulation box 1 and improving the splicing quality of the panel.

[0037] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
