[0002] Dust removal equipment used in loudspeaker manufacturing is a device specifically designed to remove dust and impurities generated during the loudspeaker manufacturing process. This type of equipment is crucial for ensuring the cleanliness of loudspeaker components.

[0003] Traditional dust removal methods mainly rely on a single suction component, which works by using negative pressure to collect airborne dust particles into a filtration system. However, this method is often ineffective in separating and removing highly adherent, complexly distributed, or magnetic metallic dust particles. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] This utility model provides a dust removal device for loudspeaker manufacturing and processing, comprising:

[0006] Dust removal assembly, the dust removal assembly comprising:

[0007] A shield, wherein the bottom end of the shield is open and is movable along the longitudinal direction;

[0008] A gas distribution plate is disposed on opposite side walls inside the shield. One of the gas distribution plates is connected to the gas outlet assembly to blow gas into the shield, and the other gas distribution plate is connected to the gas suction assembly to suck up dust.

[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0024] Example

[0025] like Figure 1 As shown, Figure 1 The diagram shown is a schematic front view of the overall structure of the dust removal device in the embodiment.

[0026] This device includes:

[0027] The machine consists of a workbench 1, a frame 2, and a dust removal assembly. The frame 2 is located on top of the workbench 1, and the dust removal assembly is located on the frame 2.

[0028] Workbench 1 is the basic support platform for the entire device, used to support or process loudspeakers, while frame 2 is used to support and fix the dust removal components.

[0029] The dust removal components include:

[0030] Mask 10, with an opening at the bottom and movable along the longitudinal direction;

[0031] Gas distribution disks 20 are disposed on opposite side walls inside the shield 10. One gas distribution disk 20 is connected to the air outlet component to blow gas into the shield 10, and the other gas distribution disk 20 is connected to the air suction component to suck up dust.

[0032] A magnetic selector 50 is provided on the inner top of the shield 10.

[0033] The shield 10 can be moved to cover the speaker processing area, creating a relatively enclosed dust-free environment inside.

[0034] The magnetic separator 50 uses magnetic force to attract metal dust or particles (such as iron filings) to improve the dust removal effect. The magnetic separator 50 can be a permanent magnet.

[0035] Two gas distribution disks 20 are respectively installed on opposite side walls inside the shield 10. The gas distribution disk 20 on the right is connected to the air outlet component and blows gas into the shield 10 to form a turbulent airflow. The gas distribution disk 20 on the left is connected to the air intake component and sucks away the dust through negative pressure to achieve the purpose of dust removal.

[0036] The air outlet component works in conjunction with the gas distribution plate 20 to facilitate the raising of dust and the adsorption of metal particles onto the magnetic separator 50. This turbulent airflow can resuspend the metal dust deposited at the bottom of the shield 10 during processing, increasing the probability of it contacting the magnetic separator 50, thereby improving the collection efficiency of metal particles. It also helps the subsequent air intake component to effectively capture and remove the overall dust.

[0037] Combining turbulent airflow with dust removal can significantly improve dust removal efficiency.

[0038] like Figure 2 , Figure 3 As shown, Figure 2 The diagram shown is a cross-sectional view of the gas distribution disk in the embodiment. Figure 3 The diagram shown is a side view of the gas distribution disk in the embodiment;

[0039] The gas distribution disk 20 includes an internal cavity 21 and several through holes 22 on the disk surface that communicate with the internal cavity 21.

[0040] The inner cavity 21 serves as a buffer and distribution space for gas;

[0041] The through holes 22 are evenly distributed or arranged in a specific array on the surface of the gas distribution disk 20 and are connected to the inner cavity 21. When the gas distribution disk 20 is connected to the air outlet component, the through holes 22 are used to spray the airflow at a uniform pressure to form a stable blowing air curtain. When the gas distribution disk 20 is connected to the air intake component, the dust in the shield 10 is evenly adsorbed through the through holes 22, thereby improving the overall dust removal efficiency.

[0042] like Figure 1 As shown, Figure 1 The diagram shown is a schematic front view of the overall structure of the dust removal device in the embodiment.

[0043] The air outlet assembly includes an air blowing pipe 31 connected to the inner cavity 21 of one of the gas distribution discs 20, and a blower 32 connected to the other end of the air blowing pipe 31. The blower 32 is fixedly mounted on the frame 2.

[0044] The blower 32 is connected to the gas distribution plate 20 on the side of the blower via the air pipe 31, and is used to provide a clean airflow with a certain pressure and flow rate to the inside of the shield 10.

[0045] The suction assembly includes a dust removal pipe 41 that communicates with the inner cavity 21 of another gas distribution plate 20, and a vacuum pump 42 that communicates with the dust removal pipe 41. The vacuum pump 42 is fixedly mounted on the frame 2.

[0046] A filter box 43 is also provided between the dust removal pipe 41 and the vacuum pump 42. The filter box 43 is equipped with a filter screen 44 that blocks its flow channel. The filter box 43 is also fixedly installed on the frame 2.

[0047] The vacuum pump 42 is connected to the gas distribution plate 20 on the same side through the dust removal pipe 41 to provide a negative pressure power source. The filter box 43 is used to perform preliminary separation and filtration of the sucked-out dust. The filter screen 44 is used to intercept the flow channel laterally to intercept and filter dust particles in the air, preventing them from entering the vacuum pump 42 and causing equipment damage or being discharged into the external environment and causing pollution.

[0048] Figure 1 The mask 10 and filter box 43 shown are viewed in cross-section.

[0049] It also includes a drive unit 60 mounted on the frame 2, the output end of the drive unit 60 being fixedly connected to the top of the shield 10;

[0050] Both the air blowing pipe 31 and the dust removal pipe 41 are telescopic flexible hoses.

[0051] The drive component 60 is preferably one of a pneumatic cylinder, a hydraulic cylinder, or an electric push rod, and the appropriate type can be selected according to actual needs. The drive component 60 is used to drive the shield 10 to move up and down in the vertical direction, thereby opening or closing the processing area and realizing the start and stop control of dust removal operation.

[0052] Both the air blowing pipe 31 and the dust removal pipe 41 are made into telescopic flexible hoses, which can be adapted to the lifting and lowering movement of the cover 10, while ensuring that the air supply component and the air suction component can still stably supply air and remove dust during the movement of the cover 10.

[0053] Working principle: The speaker to be processed is processed in the processing area on the worktable 1. The drive unit 60 is activated, which drives the shield 10 to descend longitudinally until the shield 10 covers the processing area, forming a relatively closed dust removal space.

[0054] The blower 32 is started, and air is supplied to the gas distribution plate 20 connected to it through the air pipe 31. The air is ejected through the through hole 22, forming a turbulent airflow. The turbulent airflow causes dust, especially metal particles, deposited at the bottom of the shield 10 or on the surface of the workpiece to be lifted and suspended. The lifted metal dust enters the top area of ​​the shield 10 under the action of the airflow. The magnetic separator 50 uses magnetic force to attract the metal particles, achieving preliminary dust separation.

[0055] Restart the vacuum pump 42. The vacuum pump 42 forms a negative pressure environment inside the shield 10 through the dust removal pipe 41 and the gas distribution plate 20 on the same side. The dust-laden airflow is drawn in through the through hole 22 of the gas distribution plate 20 and delivered to the filter box 43 through the dust removal pipe 41. When the airflow passes through the filter screen 44, the dust particles are intercepted and clean air is discharged from the vacuum pump 42 or recycled.

[0056] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
