Description

Technical Field

[0001] The invention relates to the technical field of musical instrument processing, in particular to a violin panel processing device. Background Art

[0002] The violin is a stringed instrument with four strings. The friction between the strings and the bow generates vibrations, which are then transmitted to the backboard through the sound post in the resonance box (body). The resonance generated by these parts produces harmonious and bright sound. The panel of the violin is one of its most important parts, which has a vital impact on the tone and appearance. The panel is usually made of spruce, which has a fine texture, soft color, high resonance, and can improve the performer's expressiveness. The production of the panel includes material selection, splicing, scraping, sound holes and sound beams, and assembling the instrument. Planking is to cut a piece of wood in the middle and then splice it in half to ensure the symmetry of the wood grain, thereby improving the sound quality. When planking, glue is evenly applied to the joint surfaces of the two pieces of wood, and they are fixed after being joined until the glue is completely solidified. The production of violin panels is still at the manual technical level, resulting in inaccurate positioning of the wood and easy deviations during joining. Moreover, since the panel is made of spruce wood, the humidity is high and there is stress in the wood, completing the planking at room temperature cannot further improve the panel stability and sound quality. Therefore, it is necessary to propose a violin panel processing equipment that can accurately plank. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] Examples, such as Figure 1 As shown, in an embodiment of the present invention, a violin panel processing device includes an insulation box 1, four supporting legs 2 and two opposing box doors 3, the four supporting legs 2 are respectively fixedly connected to the four corners of the lower surface of the insulation box 1, the two opposing box doors 3 are respectively installed on the left and right sides of the front of the insulation box 1 through hinges, a splicing mechanism 4 is installed at the bottom of the inner cavity of the insulation box 1, and a heating mechanism 5 is installed on the right side wall of the insulation box 1.

[0026] More specifically, Figure 2 and Figure 3As shown, the splicing mechanism 4 includes a support plate 41 installed at the bottom of the inner cavity of the heat preservation box 1, and slide rails 42 are horizontally installed on the front and rear sides of the upper surface of the support plate 41, and slide seats 43 are sleeved on the left and right sides of the outer walls of the slide rails 42. A motor 44 is installed at the center of the lower surface of the support plate 41, and a traction rod 45 is installed at the output end of the motor 44. Both ends of the traction rod 45 are connected to one end of a connecting rod 46 through a pin shaft, and the other end of the connecting rod 46 is connected to the lower surface of the slide 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 slide seats 43 to move inward or outward at the same time. A plurality of limit components 47 are embedded in the upper surface of the slide seat 43 from left to right, and a positioning component 48 is vertically installed at the rear end of the upper surface of the slide seat 43.

[0027] Further, such as Figure 4 As shown, the limiting assembly 47 includes an outer cylinder 471 embedded in the upper surface of the slide seat 43, a first guide rod 472 is vertically installed at the bottom of the inner cavity of the outer cylinder 471, 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, a first inclined block 475 is installed in the middle of the right side wall of the limiting column 473, the first inclined block 475 limits the rising of the limiting column 473, a box body 476 is installed on the right side wall of the outer cylinder 471, a second guide rod 477 is horizontally installed on the top of the right inner wall of the box body 476, a blocking rod 478 and a second spring 479 are respectively sleeved on the left and right sides of the outer wall of the second guide rod 477, the elastic force of the second spring 479 can push the blocking rod 478 to move left, and the blocking rod 478 can push the first inclined block 475 is blocked and can lower the height of the limiting column 473. A third guide rod 4710 is vertically installed on the lower surface of the blocking rod 478.

The left surfaces of the blocking rod 478 and the second inclined block 4711 are both inclined surfaces, and the two inclined surfaces are symmetrical up and down. When the limiting column 473 descends, the inclined surface of the first inclined block 475 squeezes the inclined surface of the blocking rod 478, allowing the blocking rod 478 to move right 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 blocking rod 478. The first inclined block 475 squeezes the inclined surface of the second inclined block 4711, allowing the blocking rod 478 and the second inclined block 4711 to move right, thereby moving the first inclined block 475 to above the blocking rod 478.

[0028] Further, such as Figure 5 and Figure 6As shown, the positioning assembly 48 includes a column 481 vertically installed on the rear end of the upper surface of the slide 43, a sleeve 482 is installed on the top of the column 481 along the front-to-back direction, a telescopic column 483 that can slide back and forth is inserted in 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, limit 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 in the inner cavity of the limit sleeve 485, a roller 487 is horizontally installed on the top of the inner side of 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 allows the roller 487 to descend under the action of gravity, and 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 advance panel to position the panel, and a rubber pad is bonded to the lower surface of the pressing plate 488. The rubber pad is elastic to prevent indentations on the panel surface.

[0029] Further, such as Figure 1 , Figure 7 and Figure 8 As shown, the heating mechanism 5 includes a distillation box 51 obliquely installed on the top of the right side wall of the insulation box 1, a flow channel 52 is opened inside the distillation box 51, and the left end of the flow channel 52 is connected to the inner cavity of the insulation box 1, the flow channel 52 is serpentinely distributed inside the distillation box 51, and the opening of the right end of the flow channel 52 becomes smaller, the flow channel 52 can prolong the residence time of the gas in the distillation box 51, and the large inner diameter of the flow channel 52 can further slow down the movement speed of the gas, so that the gas has enough time to cool down, and the water vapor in the gas is liquefied into accumulated water, and a water accumulation bucket 54 is screwed on the right end of the lower surface of the distillation box 51, and the accumulated water in the flow channel 52 can flow into the water accumulation bucket 54 along the inclined surface, and one end of the first air pipe 55 is installed at the right end of the flow channel 52, and a hot air blower 56 is installed at the other end of the first air pipe 55, and the gas is heated by the hot air blower 56, and the bottom of the hot air blower 56 is connected to the bottom of the right side wall of the insulation box 1 through a second air pipe 57, so that the hot air circulates in the insulation box 1 to provide a high-temperature dry environment.

[0030] Working principle: Step 1: According to the size of the violin panel, the limiting column 473 is pressed down to force the first inclined block 475 to press the blocking rod 478 downward, so that the blocking rod 478 moves rightward 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 blocking rod 478, the second spring 479 pushes the blocking rod 478 to move leftward, limiting the rise of the first inclined block 475, and the limiting column 473 is retracted into the outer cylinder 471; If the limiting column 473 is continuously pressed downward, the first inclined block 475 pushes the second inclined block 4711 downward, and 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 limiting column 473 is released. The first spring 474 pushes the limiting column 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 rod 478, the inclined surface of the second inclined block 4711 can move itself to the right. The first inclined block 475 is separated from the second inclined block 4711 and the stop rod 478 in turn, and the limiting column 473 extends out of the outer tube 471. Therefore, the violin panels of different sizes can be positioned by adjusting the height of the limiting column 473. Step 2: After the panel is placed on the slide 43, the telescopic column 483 is pulled forward, and the inclined surface of the guide groove 484 allows the roller 487 to descend under its own gravity. The limit sleeve 485 cooperates with the lifting column 486 to make the pressing plate 488 descend. The gravity of the pressing plate 488 presses the panel tightly on the slide 43, completing the positioning of the two spliced ​​panels; Step 3: After the glue is applied to the panel joint surface, the motor 44 drives the traction rod 45 to rotate clockwise, so that the connecting rod 46 pulls the two slide seats 43 to move inward at the same time until the two panels are in contact, so as to achieve accurate panel jointing; Step four, during the splicing process, the gas can enter from the flow channel 52 through the suction of the hot air blower 56, the heater in the hot air blower 56 heats the gas, and then the hot gas is discharged into the insulation box 1 through the second air pipe 57, thereby increasing 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 is liquefied into accumulated water. Due to the inclination of the distillation box 51, the accumulated water flows into the water accumulation barrel 54, dehumidifying the gas, creating a high temperature and dry environment for the insulation box 1, and improving the panel splicing quality.

[0031] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
