AI Technical Summary
When traditional grinding machines process lightweight materials, the debris tends to adhere to the gap between the moving plate and the fixed plate due to electrostatic adsorption and airflow vortex effect, resulting in low dust removal efficiency. This is especially true when processing wood, where dust is easily dispersed, posing safety hazards and environmental defects.
Design an environmentally friendly dust removal grinding wheel machine that uses continuous rotation of the filter kit and reverse high-pressure airflow to blow away dust, combined with a dust collection hopper and water mist spraying. The dust collection hopper sucks in debris and the water mist causes the dust to become heavier and agglomerated, thus achieving effective collection of debris and locking of dust.
It effectively prevents debris from remaining on the filter structure, keeps the filter surface clean, ensures that the working environment is not polluted, avoids dust escape, and improves dust removal efficiency and safety.

Description
Technical Field
[0001] This utility model relates to the field of musical instrument manufacturing equipment technology, and in particular to an environmentally friendly dust-removing grinding wheel machine for musical instrument production. Background Technology
[0002] Grinding wheels, as crucial surface treatment equipment in musical instrument manufacturing, are widely used in the grinding and polishing of wood, aggregates, and metal parts. The high-speed rotating grinding wheel generates a large amount of dust and debris upon contact with the workpiece. These particles not only pollute the working environment and endanger the respiratory health of operators, but can also affect the machining accuracy of precision components such as the resonating chamber of the instrument. Especially in wood processing, the fine dust is flammable and explosive, posing significant safety hazards and environmental drawbacks to traditional open-type grinding wheels.
[0003] To address the aforementioned problems, existing technologies have proposed various dust removal solutions, including an environmentally friendly dust-collecting grinding wheel machine (publication number CN118990274B). This equipment, through the installation of an adjustable chip collection device and the use of a combination of movable and fixed plates, achieves the function of dynamically adjusting the chip collection space according to the grinding wheel size. Its core technology lies in the fact that when changing to grinding wheels of different diameters, the drive mechanism moves the movable plate horizontally, ensuring that the opening width of the chip collection chamber maintains a suitable distance from the outer edge of the grinding wheel, thereby theoretically improving chip collection efficiency.
[0004] The aforementioned patent solves the compatibility problem of the chip collection structure caused by the fixed size of the grinding wheel in traditional grinding machines. However, due to electrostatic adsorption and airflow vortex effects, the chips generated by high-speed grinding easily adhere to the mating surfaces of the moving plate and the fixed plate, as well as the gaps in the slide rails, and cannot effectively slide down to the bottom collection box by gravity, resulting in continuous chip accumulation. The retained chips detach from the adhesion surface under equipment vibration or airflow disturbance and escape into the working area with the turbulence created by the rotation of the grinding wheel, significantly reducing dust removal efficiency. This escape phenomenon is even more pronounced when processing lighter wood and synthetic materials, such as spruce, maple, and carbon fiber commonly used in musical instrument manufacturing.

The grinding wheel is equipped with a grinding disc and a dust collection hopper located at the bottom of the grinding disc. A base is connected to the front of the grinding wheel, and a blower is mounted on the top of the base. A mounting plate is connected to the front of the grinding wheel, and an open ring frame is connected inside the mounting plate. A filter kit is rotatably connected inside the open ring frame. Through holes are opened on both the front and rear sides of the open ring frame. One end of the dust collection pipe communicates with the rear through hole of the open ring frame, and the other end of the dust collection pipe communicates with the bottom of the dust collection hopper. The blower communicates with the front through hole of the open ring frame. A circulation mechanism is provided on the base to maintain the effectiveness of the filter kit, and a dust-reducing component is provided on the base to absorb dust and debris.
[0007] In one embodiment, the circulation mechanism includes a gear ring, a motor, a gear, and an air outlet pipe. The gear ring is rotatably connected to the outer ring of the open ring frame, and the gear ring is connected to the filter kit. A motor is mounted on the base, and the output shaft of the motor is connected to a gear that meshes with the gear ring. A mounting frame is connected to the base, and a collection box is slidably connected inside the mounting frame. The bottom of the collection box is slidably connected to the base. A guide box is connected to the top of the mounting frame. The air inlet of the blower communicates with the through hole on the front side of the open ring frame. One end of the air outlet pipe communicates with the air outlet of the blower. The air outlet pipe passes through the front side plate of the open ring frame and communicates with it. The guide box passes through the rear side plate of the open ring frame and communicates with it. The air outlet pipe and the guide box are symmetrically connected to the open ring frame at their respective points of connection.
[0008] In one embodiment, the dust suppression component includes a water pipe, a water tank is mounted on the base, the water tank is adjacent to the mounting frame, a sealing cover is provided on the top of the water tank, one end of the water pipe is connected to the top of the mounting frame, the other end of the water pipe passes through the top plate of the water tank and is equipped with a water pump, a diversion pipe is connected to the top of the mounting frame, the diversion pipe is connected to the end of the water pipe, and the diversion pipe is provided with a plurality of spray heads.
[0009] In one embodiment, both the collection tank and the water tank are provided with a viewing window made of transparent material.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. The continuous rotation of the filter kit allows the filter surface to be constantly renewed and changed. At the same time, the reverse high-pressure airflow is used to powerfully blow away the attached debris. The dynamic cleaning mechanism prevents debris from staying on the filter structure and keeps the filter surface clean at all times.
[0016] 2. The dust is sucked into the dust collection hopper to prevent the dust from escaping. The dust first enters the collection system through the pipe, and then water mist spraying causes the dust to become heavier and clump together, achieving the effect of locking it in as soon as it is sucked in. Combined with the solidification effect of water mist, the dust is firmly locked in the collection box to ensure that the working environment is not polluted.
[0017] 3. The water collection plate guides the water flow to gather, which can continuously suppress dust even at low water levels; the dual observation windows allow staff to intuitively grasp the amount of debris accumulation and the status of the water tank, making equipment maintenance simple and precise, and effectively avoiding the performance degradation problem caused by untimely maintenance of traditional equipment.

Detailed Implementation
[0026] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.
[0027] Example: An environmentally friendly dust-removing grinding wheel machine for musical instrument production, such as... Figures 1-7 As shown, the instrument includes a grinding wheel 1, a grinding disc 101, a dust hopper 2, a suction pipe 3, a mounting plate 4, an open ring frame 5, a filter kit 6, a base 8, a blower 11, a circulation mechanism, and a dust collection assembly. The grinding wheel 1 is equipped with a grinding disc 101 and a dust hopper 2 located at the bottom of the grinding disc 101. The base 8 is connected to the front of the grinding wheel 1, and a blower 11 is mounted on top of the base 8. The mounting plate 4 is also connected to the front of the grinding wheel 1, and an open ring frame 5 is connected inside the mounting plate 4. A filter kit 6 is rotatably connected inside the open ring frame 5. Through holes are opened on both the front and rear sides of the open ring frame 5. One end of the suction pipe 3 communicates with the through hole on the rear side of the open ring frame 5, and the other end communicates with the bottom of the dust hopper 2. When the grinding disc 101 rotates at high speed to grind the musical instrument material, the material surface and the grinding disc 101 wear down synchronously, producing debris. The blower 11... The air inlet forms a negative pressure airflow through the suction pipe 3, extending the suction to the two dust collection hoppers 2 at the bottom of the grinding disc 101. The dust collection hoppers 2 capture splashing debris while drawing in air, forming a directional airflow channel, allowing the debris to enter the interior of the open ring frame 5 along the dust collection hoppers 2 and the suction pipe 3. The filter kit 6 has annular pleats facing the center point inside, and the pleats fit against the inner wall of the open ring frame 5, blocking the airflow from flowing around the filter kit 6. The blower 11 is connected to the through hole on the front side of the open ring frame 5. The airflow carrying debris is intercepted by the filter kit 6 on the inner wall of the open ring frame 5, and the dust is adsorbed on the surface of the filter kit 6. The purified gas then enters the air inlet of the blower 11, completing the primary dust collection closed loop. The base 8 is equipped with a circulation mechanism to maintain the effectiveness of the filter kit 6, and a dust-reducing component to absorb dust and debris.
[0028] like Figures 4-6 As shown, the circulation mechanism includes a gear ring 7, a motor 9, a gear 10, an air outlet pipe 12, a guide box 13, a collection box 14, and a mounting frame 15. The gear ring 7 is rotatably connected to the outer ring of the open ring frame 5, and the gear ring 7 completely seals the open ring frame 5. The gear ring 7 is connected to the filter kit 6. The motor 9 is mounted on the base 8, and the output shaft of the motor 9 is connected to the gear 10. The gear 10 meshes with the gear ring 7. The mounting frame 15 is connected to the base 8, and the collection box 14 is slidably connected inside the mounting frame 15. The bottom of the collection box 14 is slidably connected to the base 8. The guide box 13 is connected to the top of the mounting frame 15. The air inlet of the blower 11 is connected to the through hole on the front side of the open ring frame 5. One end of the air outlet pipe 12 is connected to the air outlet of the blower 11. The air outlet pipe 12 passes through the front side plate of the open ring frame 5 and is connected to it. The guide box 13 passes through the rear side plate of the open ring frame 5 and is connected to it. The air outlet pipe 12 and the guide box 13 are symmetrically connected to the open ring frame 5 at the front and rear.
[0029] like Figure 6 and Figure 7 As shown, the dust suppression assembly includes a water tank 16, a sealing cover 17, a water pipe 18, a water pump 19, a diversion pipe 20, and spray nozzles 21. The water tank 16 is installed on the base 8 and is adjacent to the mounting frame 15. The top of the water tank 16 is provided with a sealing cover 17. One end of the water pipe 18 is connected to the top of the mounting frame 15, and the other end of the water pipe 18 passes through the top plate of the water tank 16 and is connected to the water pump 19. The top of the mounting frame 15 is connected to the diversion pipe 20, which is connected to the end of the water pipe 18. The diversion pipe 20 is provided with several spray nozzles 21. The water pump 19 draws water from the bottom of the water tank 16, and the water flows through the water pipe 18 and the diversion pipe 20 to the array of spray nozzles 21 on the top of the mounting frame 15. The falling debris and dust collide with the water mist and agglomerate, accelerating the settling. The humidity inside the tank is maintained continuously, suppressing the secondary raising of dust.
[0030] like Figure 1 and Figure 6 As shown, it also includes an observation window 22. Both the collection box 14 and the water tank 16 are equipped with observation windows 22 made of transparent material, providing a visual window so that staff can directly observe the internal state by transmitting light.
[0031] like Figure 6 As shown, it also includes a water-gathering plate 23. The bottom of the water tank 16 is connected to the water-gathering plate 23. The lowest point of the V-shaped inclined structure at the bottom of the water tank 16 is aligned with the water inlet of the water pump 19. Under the action of gravity, the water flow naturally converges to the pump inlet.
[0032] like Figure 6 As shown, it also includes a stabilizer 24. The stabilizer 24 is connected to the water tank 16. The middle part of the water pipe 18 passes through the stabilizer 24 to support the water pipe 18, prevent the water pipe 18 from bending at an acute angle, and maintain smooth water flow.
[0033] like Figure 6 As shown, it also includes a pull rope 25. The top of the sealing cover 17 is connected to the pull rope 25, and the other end of the pull rope 25 is fixedly connected to the top surface of the water tank 16.
[0034] like Figure 2 and Figure 6 As shown, it also includes a guide plate 26. The base 8 is connected to a guide plate 26 with an inclined surface facing the upper left. The top left side of the mounting frame 15 is connected to a guide plate 26 with an inclined surface facing the lower left. The double inclined surfaces work together to enable the collection box 14 to be pushed in and positioned, improving installation efficiency.
[0035] When the material is processed and polished, both the grinding disc 101 and the material are worn out. At the same time, the staff turns on the blower 11. The air inlet of the blower 11 draws in air through the dust suction pipe 3, which then extends the air inlet to the two dust collection hoppers 2. The dust collection hoppers 2 capture debris while drawing in air, so that the debris enters with the airflow, thus ensuring that the debris does not escape, but follows the airflow along the dust collection hoppers 2 and the dust suction pipe 3 into the open ring frame 5. The airflow carrying debris is filtered by the filter kit 6 in the open ring frame 5. The annular pleats of the filter kit 6 fit tightly against the inner wall of the open ring frame 5, forcing the airflow to pass radially through the filter material rather than circling around it. Then, the remaining airflow enters the blower 11 after passing through the filter kit 6, completing the collection of debris.
[0036] The motor 9, started by the operator, drives the gear 10 to rotate. As the gear 10 rotates counterclockwise, it drives the meshing gear ring 7 to rotate clockwise, thereby rotating the filter kit 6 inside. The lower end of the filter kit 6 filters the debris entering from the suction pipe 3. As the filter kit 6 rotates clockwise, the position of the filter changes, ensuring both airflow efficiency and filtration effect. As the filter kit 6 rotates, the air drawn by the blower 11 is ejected from the outlet pipe 12 and re-enters the open ring frame 5. The side of the filter kit 6 facing the suction pipe 3 filters debris, and the airflow from the outlet pipe 12 blows the debris filtered by the filter kit 6 off the open ring frame 5, causing the debris to enter the collection box 14 through the guide box 13, thus cleaning the filter kit 6 and extending its single-use lifespan.
[0037] Water pump 19 draws water from water tank 16. The water flows along water pipe 18 and diversion pipe 20 and is sprayed out from spray head 21. Debris and dust entering collection box 14 are adsorbed and condensed by water mist and fall downward, reducing the time suspended in the air. Finally, they are collected by collection box 14, maintaining a dust-suppressing environment and completing the collection of debris and dust.
[0038] After one grinding disc 101 is used up, a new grinding disc 101 needs to be installed. At this time, the motor 9 and water pump 19 are turned off, the collection box 14 is pulled out, and the debris and dust collected in the collection box 14 are disposed of. After cleaning, it is pushed back into the installation frame 15. Before cleaning the collection box 14, it can also be observed through the observation window 22. If there is very little debris in the collection box 14, there is no need for excessive cleaning. The remaining water level in the water tank 16 can be observed at any time through the observation window 22 on the side of the water tank 16. Moreover, the water collection plate 23 can... Water is gathered at the water pump 19, thus effectively utilizing the water in the water tank 16. When the water in the water tank 16 is about to run out, the sealing cover 17 is opened through the observation window 22 to replenish the water tank 16. The rope 25 suspends the sealing cover 17 to effectively prevent the sealing cover 17 from falling off or being lost. When the collection box 14 is pushed in, the guide plate 26 on the left side of the mounting frame 15 and the base 8 can guide the collection box 14. The inclined structure of the guide plate 26 guides the collection box 14 to slide into the mounting frame 15 along the set trajectory.
[0039] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
