[0020] 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.

[0021] Example

[0022] like Figure 1 As shown, Figure 1 The diagram shown is a front view of the overall painting device in the embodiment;

[0023] This device includes:

[0024] Workbench, work rack, support structure 10, painting structure and drying structure 20;

[0025] The work frame is set on the top of the workbench, the support structure 10 is rotatably set on the workbench, the speaker housing 1 is installed on the support structure 10, the painting structure is set on one side of the support structure 10, and the drying structure 20 is movably set on the work frame along the longitudinal direction and corresponds to the position of the support structure 10.

[0026] The workbench and work rack form the foundation of the entire device, providing mounting support points for other components;

[0027] After the speaker housing 1 is installed on the support structure 10, it can rotate with it. The painting structure is set on one side of the support structure 10 and is used to paint the speaker housing 1. When the support structure 10 rotates, the painting structure can evenly spray the paint onto the surface of the speaker housing 1. After the painting is completed, the drying structure 20 heats and dries the painted speaker housing 1 to accelerate the curing of the paint.

[0028] like Figure 2 As shown, Figure 2 The diagram shown is a cross-sectional view of the cooperation between the support platform and the speaker housing in the embodiment;

[0029] Support structure 10 includes:

[0030] Platform section 11 and positioning post 12 provided at the top of platform section 11;

[0031] The platform section 11 is hollow inside and a collection box 13 is movably inserted inside. The top of the collection box 13 is open. The top surface of the platform section 11 is provided with a leakage hole 14 that communicates with its interior. The leakage hole 14 is located on the outer side of the bottom end of the speaker housing 1. The leakage hole 14 guides the paint that slides off the outer wall of the speaker housing 1 to the collection box 13 inside the platform section 11.

[0032] The positioning post 12, located at the center of the top of the platform section 11, is used to position and lock the speaker housing 1 in place, ensuring its stability during rotation.

[0033] The inclusion of collection box 13 and leakage hole 14 allows the support structure 10 to also integrate waste paint collection function, thereby improving the environmental friendliness and cleanliness of the equipment.

[0034] In one embodiment, the drain hole 14 is annularly formed on the top surface of the platform portion 11 and arranged around the bottom outer side of the speaker housing 1. The drain hole 14 can guide excess paint and dripping liquid that slides off the outer wall of the speaker housing 1 during the painting process into the collection box 13, thereby preventing paint from dripping onto the workbench or other parts and causing pollution or affecting the operation of the equipment.

[0035] like Figure 1 As shown, Figure 1 The diagram shown is a front view of the overall painting device in the embodiment;

[0036] The spray painting structure includes:

[0037] Paint storage box 31,

[0038] The oil pump 32 has its input end connected to the paint storage tank 31 via a connecting pipe 33, and its output end connected to the nozzle 34 via the connecting pipe 33. The oil pump 32 draws paint from the paint storage tank 31 and sprays it out through the nozzle 34.

[0039] The paint storage tank 31 is used to store the paint to be sprayed. The oil pump 32 serves as a power source and, together with the connecting pipe 33, delivers the paint in the paint storage tank 31 to the nozzle 34. The nozzle 34 atomizes the paint and sprays it evenly onto the surface of the rotating speaker housing 1.

[0040] like Figure 3 As shown, Figure 3 The diagram shown is a cross-sectional view of the drying structure in the embodiment;

[0041] The drying structure 20 includes:

[0042] The cover 21 has an opening at the bottom, and several drying components 22 are evenly distributed and embedded on the inner side wall of the cover 21.

[0043] The cover 21 is a semi-enclosed shell structure with an opening at the bottom. The drying component 22 is a conventional material with an electric heating wire or heating tube. The drying component 22 can accelerate the evaporation of solvents in the paint and the curing reaction, thereby improving the painting efficiency.

[0044] Specifically, a motor 40 is installed at the bottom of the workbench, and the output end of the motor 40 passes through the table surface and is connected to the platform part 11 of the support structure 10. The motor 40 serves as the driving source for the support structure 10, driving the support structure 10 to rotate.

[0045] Specifically, the work frame is equipped with an electric telescopic rod 50, the output end of which is connected to the cover 21 of the drying structure 20. The electric telescopic rod 50 serves as the driving source for the drying structure 20, driving it to move vertically along the longitudinal direction so that it can accurately cover the area to be dried.

[0046] Working principle: When using this device, first install the speaker housing 1 to be sprayed on the positioning column 12 of the support structure 10 and check whether the fixation is firm to ensure that it does not shift during rotation. Then start the motor 40, which drives the support structure 10 to rotate slowly. The speaker housing 1 rotates synchronously with the support structure 10 to prepare for uniform spraying. Then turn on the oil pump 32, which delivers the paint in the paint storage tank 31 to the nozzle 34 through the connecting pipe 33. The nozzle 34 atomizes the paint and sprays it evenly on the surface of the rotating speaker housing 1. Excess paint slides down the outer wall of the speaker housing 1 and flows into the platform part 11 through the leakage hole 14. Waste paint is received by the collection box 13 to avoid environmental pollution. The collection box 13 can be pulled out to process the paint collected inside. Finally, start the electric telescopic rod 50 to drive the cover 21 to move downward until it covers the speaker housing 1. Then turn on the drying component 22, which is powered on and heated. The temperature inside the cover 21 gradually rises, accelerating the evaporation of solvent in the paint and promoting the curing of the paint film.

[0047] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
