Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a cleaning device for producing speaker grilles, comprising a cleaning chamber 1 and a rotating step carrier plate 11. A water storage box 3 is placed at the lower end of the cleaning chamber 1, and a filter screen 24 is horizontally placed on the upper end of the water storage box 3. A circulation pump 4 is installed at the left end of the cleaning chamber 1. The inlet end of the circulation pump 4 is connected to the water storage box 3 via a pipe. A circulation pipe 5 is longitudinally installed at the upper end of the circulation pump 4. The upper end of the circulation pipe 5 is inserted into the cleaning chamber 1, and multiple branch pipes 6 are installed at the outlet end of the circulation pipe 5 via a tee. Each branch pipe 6 has a spray nozzle 8 and a regulating valve 7 installed at its lower end. A bearing is embedded in the upper end of the cleaning chamber 1, and a drive shaft 16 is installed through the bearing. A driven gear 17 is installed at the upper end of the drive shaft 16, and the lower end of the drive shaft 16 is connected by a flange and bolts. Fixed to the rotating step carrier plate 11, the rotating step carrier plate 11 is suspended inside the cleaning chamber 1. The step surface of the rotating step carrier plate 11 has multiple mesh cover placement slots 14, and the main body of the speaker mesh cover 15 is horizontally placed in each of the multiple mesh cover placement slots 14. The lower end of each of the multiple mesh cover placement slots 14 has a through-hole 13. A servo motor 19 is longitudinally installed on the upper left side of the cleaning chamber 1. A drive gear 18 is installed on the shaft end of the servo motor 19. A drying chamber is opened on the upper right side of the cleaning chamber 1, and an outer cylinder 20 is installed in the drying chamber by bolts. Inside the outer cylinder 20, a dustproof net 21, a fan 22 and a disc heating tube 23 are horizontally installed from top to bottom. This design solves the problem that traditional speaker mesh cleaning is mostly static soaking, which makes it difficult to cover the complex structure of the mesh cover and easily leaves stains.

[0019] As the first embodiment of this utility model: the front end of the cleaning box 1 is provided with an arc-shaped groove, and the upper and lower sides of the right end of the arc-shaped groove are fixed with bending pieces. A fixed shaft is longitudinally fixed between the two bending pieces, and a movable baffle 2 is slidably sleeved on the outside of the fixed shaft. The added movable baffle 2 facilitates the covering of the front opening of the cleaning box 1. A drain pipe is installed on the left side of the front end of the water storage box 3, and the drain pipe passes through the cleaning box 1. The added drain pipe facilitates the discharge of liquid in the water storage box 3. The spray ends of multiple water nozzles 8 are all directed towards the upper left side of the rotating step carrier plate 11. By having the spray ends of multiple water nozzles 8 all directed towards the upper left side of the rotating step carrier plate 11, the speaker grille body 15 placed on the rotating step carrier plate 11 can be sprayed and cleaned.

[0020] An annular rail 9 is bolted to the inside of the cleaning chamber 1. A lightening hole 12 is provided in the middle of the lower end of the rotating step plate 11. An annular groove 10 is provided on the edge of the rotating step plate 11, and the annular rail 9 slides into the annular groove 10. The addition of the annular rail 9 sliding into the annular groove 10 ensures the stability of the rotating step plate 11 when it is driven to rotate. The driven gear 17 meshes with the driving gear 18 for transmission. Through the added driven gear 17 meshing with the driving gear 18, the servo motor 19 can drive the driven gear 17 to mesh and rotate when it is working through the driving gear 18.

[0021] As a second embodiment of this utility model: This utility model is used for cleaning existing circular sheet-shaped speaker grilles on the market. During cleaning, the servo motor 19 is started, which drives the drive gear 18 to rotate, and the driven gear 17 rotates in response. This drives the transmission shaft 16 and the rotating step plate 11 to rotate, thereby achieving the rotation of multiple speaker grille bodies 15 (because the multiple speaker grille bodies 15 are horizontally inserted into multiple grille placement slots 14, they will not be flung off when the rotating step plate 11 rotates). Then, the circulation pump 4 is started. The circulation pump 4 draws the cleaning fluid from the water storage box 3 through the pipe and supplies it to multiple water spray heads 8 through the circulation pipe 5 and multiple branch pipes 6. The multiple water spray heads 8 can spray water to rinse the rotating multiple speaker grille bodies 15. The water and dust passing through the multiple speaker grille bodies 15 pass through the multiple grille placement slots 14 and multiple The water drips down through the drain hole 13, then passes through the filter screen 24 and returns to the water storage box 3. After completion, the circulation pump 4 is turned off, and the fan 22 and the disc heating tube 23 are started. The fan 22 blows air towards the rotating rotating step plate 11, and the air is heated by the disc heating tube 23 to form hot air, thereby drying the rotating multiple speaker grille bodies 15. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
