[0002] With the rapid development of the electronics industry, people's demand for headphones is also increasing rapidly. In order to ensure the sales of headphones, manufacturers often beautify the appearance of headphones at the beginning of production. The beautification of headphone decorative covers is particularly important, and spray painting equipment is often used in the beautification process of headphone decorative covers.

[0003] Specifically, a painting equipment for producing headphone decorative covers, patent number CN214554671U, has the following defects when painting decorative covers: painting work is carried out in an exposed environment, and paint mist will permeate the workshop, affecting the working environment and the health of workers. Furthermore, since the paint on the decorative covers takes a long time to dry naturally, if they are not dried before being taken out, the paint surface is easily scratched. The long drying time also seriously affects production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a painting device for processing headphone decorative covers.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A painting device for processing headphone decorative covers includes a machine base, a frame on the top of the machine base, a paint storage tank on the frame, a paint spray head fixed to the paint storage tank through a pipe, and a pump body on the pipe.

[0007] The machine base has a groove located directly below the spray nozzle on its top. A support mechanism driven by an electric push rod is located at the bottom of the groove. Guide slopes are also provided on the two sides of the opening at the top of the groove. A protective cylinder is located on the top of the machine base. The groove and the spray nozzle are located on the upper and lower sides of the opening of the protective cylinder, respectively. The protective cylinder is driven by a hydraulic rod. A funnel-shaped guide bucket is located at the bottom of the protective cylinder. Gas channels corresponding to the guide slopes are provided on both sides of the protective cylinder. Ventilation holes communicating with the gas channels are evenly distributed on the inner wall of the protective cylinder below the top of the guide bucket. An inlet pipe and an outlet pipe communicating with the corresponding gas channels are also provided on the outer side of the protective cylinder.

[0008] Preferably, the largest opening end of the guide bucket is fixedly connected to the inner wall of the protective cylinder, the vent is located below the connection between the guide bucket and the protective cylinder, and the support mechanism is located directly below the bottom opening of the guide bucket.

[0009] Preferably, the grid plate formed by the guide bucket and the protective cylinder is located between the corresponding top ends of the two sets of gas channels, and both the grid plate and the bottom end of the guide bucket are higher than the horizontal plane of the bottom end of the protective cylinder.

[0010] Preferably, the support mechanism includes a base, with multiple sets of vertical rods arranged circumferentially on the top of the base, and a horizontal rod arranged on one side of each vertical rod.

[0011] Preferably, a recycling bin is provided at the bottom of the machine, and the recycling bin is connected to the bottom of the groove through a recycling pipe.

[0018] The following examples, in conjunction with the appendix, illustrate the concepts. Figure 1-2 The technical solution of the present invention will be further described in detail below.

[0019] A painting device for processing headphone decorative covers includes a machine base 1, a frame 2 is provided on the top of the machine base 1, a paint storage tank 3 is provided on the frame 2, a paint spray head 4 is fixed to the paint storage tank 3 through a metal pipe, and a pump body is provided on the pipe.

[0020] The machine base 1 has a groove 5 located directly below the paint spray head 4 on its top. A support mechanism 6 driven by an electric push rod 7 is located at the bottom of the groove 5. Guide slopes 8 are also provided on the two sides of the top opening of the groove 5. A protective cylinder 9 is provided on the top of the machine base 1. The groove 5 and the paint spray head 4 are located on the upper and lower sides of the opening of the protective cylinder 9, respectively. The protective cylinder 9 is driven by a hydraulic rod 10. A funnel-shaped guide bucket 11 is provided at the bottom of the protective cylinder 9. Gas channels 12 corresponding to the guide slopes 8 are provided in the corresponding side walls of the protective cylinder 9. Ventilation holes 13 communicating with the gas channels 12 are evenly provided on the inner wall of the protective cylinder 9 at the bottom of the top of the guide bucket 11. An air inlet pipe 14 and an air outlet pipe 15 communicating with the corresponding gas channels 12 are also provided on the outside of the protective cylinder 9. The air inlet pipe 14 is connected to a hot air blower through a hose.

[0021] like Figure 1 As shown, the maximum opening end of the guide bucket 11 is fixedly connected to the inner wall of the protective cylinder 9, the vent 13 is located below the connection between the guide bucket 11 and the protective cylinder 9, and the support mechanism 6 is located directly below the bottom opening of the guide bucket 11.

[0022] like Figure 2 As shown, the grid plate 16 formed by the flow guide hopper 11 and the protective cylinder 9 is located between the corresponding top ends of the two sets of gas channels 12. The bottom ends of the grid plate 16 and the flow guide hopper 11 are both higher than the bottom horizontal plane of the protective cylinder 9.

[0023] The support mechanism 6 includes a base 61, with multiple sets of vertical rods 62 arranged circumferentially on the top of the base 61, and a horizontal rod 63 arranged on one side of each vertical rod 62. In this embodiment, there are three sets of vertical rods 62, which are evenly arranged on the base 61 to hold the edge of the decorative cover, while the three sets of horizontal rods 63 support the bottom of the decorative cover, making it suspended.

[0024] Preferably, a recycling bin 17 is provided at the bottom of the machine base 1, and the recycling bin 17 is connected to the bottom of the groove 5 through a recycling pipe 18. Paint that may drip into the bottom of the groove 5 can flow into the recycling bin 17 through the recycling pipe 18 for recycling.

[0025] like Figure 1As shown, the top of the paint spray head 4 is provided with an annular plate 19 whose edge is in contact with the inner wall of the protective cylinder 9, and the top of the protective cylinder 9 is provided with an annular seat 20 located above the annular plate 19. The output shaft of the hydraulic rod 10 is fixedly connected to the annular seat 20, and the hydraulic rod 10 is mounted on the frame 2.

[0026] The method of using the present invention is as follows: the electric push rod 7 drives the base 61, the vertical rod 62 and the horizontal rod 63 to move to the outside of the groove 5 so that people can place the decorative cover between the three sets of vertical rods 62 and support and fix it by the horizontal rod 63. Then the base 61 drives the decorative cover to move down into the groove 5 for processing.

[0027] At this time, the hydraulic rod 10 drives the annular seat 20 to move the protective cylinder 9 down, so that the annular seat 20 abuts against the top surface of the annular plate 19, and the protective cylinder 9 abuts against the top of the machine base 1. Then the pump body guides the paint liquid in the paint storage tank 3 into the paint spray head 4 through the pipeline and sprays it out, thereby painting the decorative cover end face on the support mechanism 6 in the groove 5. At this time, due to the presence of the guide bucket 11, the sprayed paint liquid will not come into contact with the vent hole 13 and enter the gas channel 12. In the above process, since the painting work is carried out in the closed space formed by the protective cylinder 9, the annular seat 20, the annular plate 19 and the groove 5, the paint mist will not diffuse into the production workshop and affect the working environment or the health of the workers.

[0028] After the paint is applied, the hot air blower guides the hot airflow through the air inlet pipe 14 into the right-side gas channel 12, from which it is ejected through the corresponding vent 13. At this time, the hot airflow is guided by the side wall of the guide bucket 11 and the right-side guide slope 8, so that the hot airflow flows into the groove 5 and contacts the end face of the decorative cover, thereby drying it. Then, the gas flows through the left-side guide slope 8 to the lower left side of the guide bucket 11, and enters the left-side gas channel 12 through the left-side vent 13, is discharged through the air outlet pipe 15, and is then introduced into the air purification equipment for treatment through the connecting pipe. In the above process, the grid plate 16 blocks the hot airflow that is introduced into the cavity formed between the guide bucket 11 and the side wall of the protective cylinder 9 before it enters the groove 5 to dry the decorative cover, and instead flows directly to the left-side vent 13 and is discharged through the left-side gas channel 12 and the air outlet pipe 15.

[0029] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
