Description

Technical Field

[0001] The invention relates to the technical field of guitar processing, and in particular to a guitar processing device. Background Art

[0002] Guitar is a popular string instrument with a long history and rich cultural connotations. It can be used as a solo instrument or for accompaniment, and is widely used in various music styles such as classical music, pop music, rock music, folk music, etc. The guitar is usually composed of several parts: the body, neck, headstock, bridge and strings. After the initial assembly of the guitar using materials, it needs to be fully polished to ensure a smooth surface for subsequent painting. At present, the polishing of the guitar is mainly to use a grinder to polish a large area, and then manually polish the areas that the grinder cannot polish. After the polishing is completed, the dust on the surface of the guitar is cleaned, and the guitar is painted after the cleaning is completed. However, the processing method of this kind of guitar is that, first, mechanical polishing and manual polishing need to be switched during polishing, so the efficiency is relatively low when it is polished manually. Second, there is a lot of dust on the guitar after polishing, so the workload of cleaning is large, and it takes a lot of time to clean the dust on the surface of the guitar, which also affects the processing efficiency of the guitar. Summary of the invention

[0003] The present invention aims to provide a guitar processing device to solve the problem that grinding affects the processing efficiency in the current guitar processing process.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a guitar processing device, comprising a dust collecting box and a polishing mechanism, the upper surface of the dust collecting box is in a concave shape toward the bottom of the dust collecting box, the upper surface of the dust collecting box is evenly distributed with a plurality of through holes, the outer bottom of the dust collecting box is fixedly connected to a negative pressure pump, the air inlet of the negative pressure pump is connected to the inside of the dust collecting box; the upper surface of the dust collecting box is fixedly connected to a connecting rod, and a horizontally arranged placement plate is fixedly connected to the connecting rod;

[0005] The polishing mechanism includes multiple support rods, which are vertically fixed on the dust collecting box. The top ends of the multiple support rods are fixedly connected to the same rectangular frame, a movable plate is slidably connected to the rectangular frame laterally, and a movable rod is slidably connected to the lower surface of the movable plate. The sliding direction of the movable rod is perpendicular to the sliding direction of the movable plate. The bottom end of the movable rod is fixedly connected to a motor with an output shaft vertically downward, and a fan blade with an air outlet facing downward is coaxially fixedly connected to the middle part of the output shaft of the motor. A polishing head is detachably provided at the end of the output shaft of the motor, and the polishing head is used to polish the surface of the guitar. The polishing head includes a disc polishing head and a cylindrical polishing head.

[0006] The working principle of the present invention is as follows: when in use, the guitar to be polished is placed on the placement board. Since the movable plate is slidably connected to the rectangular frame horizontally, and the movable rod is slidably connected to the lower surface of the movable plate, the movable rod can be pulled or pushed according to the position of the guitar, and then the movable rod and the movable plate move synchronously, so that the motor fixedly connected to the bottom end of the movable rod moves to the guitar, and the polishing head is in contact with the surface of the guitar; then the negative pressure pump and the motor are started synchronously, and since the air inlet of the negative pressure pump is connected to the inside of the dust collecting box, and the upper surface of the dust collecting box is evenly provided with a plurality of through holes, when the negative pressure pump is running, the gas inside the dust collecting box will be extracted to form a negative pressure state, and the dust collecting box will pass through the negative pressure under the action of the negative pressure. The through hole draws outside air into the dust box, and when the motor is running, the fan blades and the grinding head are driven to rotate synchronously through the output shaft. When the fan blades rotate, a downward airflow is generated, and when the grinding head rotates, the surface of the guitar is grinded. The dust generated during grinding is blown away from the surface of the guitar by the airflow generated by the rotation of the fan blades and then falls on the constricted upper surface of the dust box. In the process of dust falling, the dust is attracted by the negative pressure at the through hole and then sucked into the dust box. After grinding a large area of ​​the guitar surface with the disc grinding head, the disc grinding head can be removed and replaced with a cylindrical grinding head. The cylindrical grinding head can be used to grind the curved surface of the side of the guitar and other small areas.

[0007] Beneficial effects of the present invention:

[0008] 1. When using this solution to polish a guitar, first use a disc polishing head to polish a large area of ​​the guitar. After the large area is polished, replace the disc polishing head with a cylindrical polishing head. Use the cylindrical polishing head to polish the curved surface of the side of the guitar and other small areas. In this way, the entire process is polished by mechanical polishing, which greatly improves the efficiency of polishing the guitar.

[0009] 2. During the polishing process, the output shaft of the motor drives the fan blades to rotate and generate a downward airflow. In this way, the fan blades will blow the dust generated during polishing away from the surface of the guitar, greatly improving the cleanliness of the guitar surface and reducing the workload of subsequent cleaning of the guitar, thereby achieving the purpose of improving cleaning efficiency.

[0010] 3. During the polishing process, the fan blades will blow away the dust on the surface of the guitar, so that the worker can see the state of the polished surface of the guitar more clearly, find uneven or unpolished areas in time, and then correct the polished areas, reducing the number of times the same area needs to be repeatedly polished, thereby improving the polishing efficiency of the guitar.

[0011] 4. During the polishing process, the dust is blown away from the surface of the guitar, which reduces the interference of dust on the polishing head, making the entire polishing more uniform and smooth, improving the quality of guitar polishing. Compared with the existing polishing method, the fan blades blow the dust away from the surface of the guitar, so that the polishing work can be kept continuous, without frequently stopping the polishing process to clean the dust, thereby further improving the polishing efficiency of the guitar.

[0012] 5. Use a negative pressure pump to create negative pressure inside the dust box, so that the dust box can absorb the dust blown off the surface of the guitar through the through holes, reducing the possibility of a large amount of dust during the guitar polishing process.

[0013] Furthermore, the moving rod is a moving rod made of a telescopic rod. The purpose is that the height of the grinding head can be effectively adjusted through this arrangement, which is convenient for grinding.

[0014] Furthermore, a downwardly inclined arc plate is fixedly connected to the top of each through hole, and the bottom end of the arc plate is located at the upper half of the through hole. The purpose is to block the airflow that hits the upper surface of the dust collecting box and then flows back through the arc plate and guide it into the through hole.

[0015] Furthermore, the bottom of the dust collecting box is funnel-shaped, and the lowest point of the bottom of the dust collecting box is connected to a dust exhaust pipe, and a switch valve is provided on the dust exhaust pipe. The purpose is to facilitate the dust entering the dust collecting box to fall to the bottom of the dust collecting box under the action of gravity and gather, and then open the switch valve to discharge the dust collecting box through the dust exhaust pipe.

[0016] Furthermore, the air inlet of the negative pressure pump is connected to the top of the wall of the dust collecting box, and a filter is detachably connected to the air inlet of the negative pressure pump. The purpose is to reduce the possibility of dust entering the negative pressure pump through the air inlet of the negative pressure pump through this arrangement, thereby ensuring the normal operation of the negative pressure pump.

[0021] The embodiment is basically as shown in the attached Figure 1 and attached Figure 2 As shown:

[0022] A guitar processing device comprises a dust collecting box 8 and a polishing mechanism. The upper surface of the dust collecting box 8 is in a concave shape that is concave toward the bottom of the dust collecting box 8. A plurality of through holes 5 are evenly distributed on the upper surface of the dust collecting box 8. A downwardly inclined arc plate 7 is fixedly connected to the top of each through hole 5. The bottom of the dust collecting box 8 is in a funnel shape. A dust exhaust pipe 10 is connected to the lowest point of the bottom of the dust collecting box 8. A switch valve 11 is provided on the dust exhaust pipe 10. A negative pressure pump 9 is fixedly connected to the outer bottom of the dust collecting box 8. The air inlet of the negative pressure pump 9 is connected to the top of the box wall of the dust collecting box 8. A filter screen 6 is detachably connected to the air inlet of the negative pressure pump 9. A connecting rod 12 is fixedly connected to the upper surface of the dust collecting box 8. A horizontally arranged placement plate 13 is fixedly connected to the connecting rod 12. The height of the placement plate 13 is lower than the height of the top edge of the dust collecting box 8.

[0023] The polishing mechanism includes multiple support rods 3, which are vertically fixed on the dust collecting box 8. The top ends of the multiple support rods 3 are fixedly connected to the same rectangular frame 2. A movable plate 1 is horizontally slidably connected to the rectangular frame 2. The lower surface of the movable plate 1 is slidably connected to a movable rod 4 in a vertical state. The sliding direction of the movable rod 4 is perpendicular to the sliding direction of the movable plate 1. The movable rod 4 is made of a telescopic rod. The bottom end of the movable rod 4 is fixedly connected to a motor 16 with an output shaft vertically downward. The middle part of the output shaft of the motor 16 is coaxially fixedly connected to a fan blade 15 with an air outlet facing downward. The end of the output shaft of the motor 16 is detachably provided with a polishing head 14, which is used to polish the surface of the guitar. The polishing head 14 includes a disc polishing head 14 and a cylindrical polishing head 14.

[0024] The specific implementation process is as follows:

[0025] When in use, the guitar to be polished is placed on the placement plate 13. Since the movable plate 1 is slidably connected to the rectangular frame 2 horizontally, and the movable rod 4 is slidably connected to the lower surface of the movable plate 1, the movable rod 4 can be pulled or pushed according to the position of the guitar, and then the movable rod 4 and the movable plate 1 move synchronously, so that the motor 16 fixedly connected to the bottom end of the movable rod 4 moves to the guitar, and the polishing head 14 is in contact with the surface of the guitar; then the negative pressure pump 9 and the motor 16 are started synchronously. Since the air inlet of the negative pressure pump 9 is connected to the inside of the dust box 8, and the upper surface of the dust box 8 is evenly provided with a plurality of through holes 5, when the negative pressure pump 9 is running, the gas inside the dust box 8 will be extracted to form a negative pressure state, and the dust box 8 will suck the outside air into the dust box 8 through the through holes 5 under the action of the negative pressure, and the motor 16 During operation, the fan blades 15 and the grinding head 14 are driven to rotate synchronously through the output shaft. When the fan blades 15 rotate, an airflow blowing downward is generated. When the grinding head 14 rotates, the surface of the guitar is ground. The dust generated during the grinding is blown away from the surface of the guitar by the airflow generated by the rotation of the fan blades 15 and then falls on the constricted upper surface of the dust box 8. In the process of dust falling, the dust is attracted by the negative pressure at the through hole 5 and then sucked into the dust box 8. The arc plate 7 blocks the airflow that flows back after hitting the upper surface of the dust box 8 and guides it into the through hole 5. After the disc grinding head 14 is used to grind a large area of ​​the guitar surface, the disc grinding head 14 can be removed and replaced with a cylindrical grinding head 14. The cylindrical grinding head 14 is used to grind the curved surface of the side of the guitar and other small areas.
