[0003] The patent application CN202322637696.6, entitled "A Spraying Device for the Surface of Automotive Plastic Parts," cannot flexibly adjust the spraying angle and position during actual use. It can only spray the parts from a single direction, which makes it difficult to ensure comprehensive and effective spraying coverage of the plastic parts of the automotive air conditioning vents. This not only reduces work efficiency but also affects the spraying quality of the products, and has significant limitations in practical applications. In view of this, a spraying device for automotive air conditioning vent plastic parts is proposed to solve the above problems. Utility Model Content

[0010] The above technical solution facilitates the drying of plastic parts of automotive air conditioning vents after spraying by injecting hot air into the spraying box using a hot air blower.
[0011] As a preferred embodiment of this utility model, a receiving box is placed on the inner bottom surface of the spraying box.
[0012] The above technical solution facilitates the collection of waste materials during spraying.
[0013] As a preferred embodiment of this utility model, a box body is fixedly installed on the rear side of the spray box, and threaded rods are installed on the left and right inner wall surfaces of the box body.

[0021] 2. The paint in the material tank is extracted by the material pump and transported through the material conveying pipe to the plastic parts of the car air conditioning vent that are clamped after spraying, so as to realize the spraying process of the plastic parts of the car air conditioning vent.
[0022] 3. By starting the drive motor, the mounting shaft drives the clamping plate to rotate, thereby causing the plastic parts of the car air conditioning vent that are clamped and fixed to rotate synchronously, thus achieving comprehensive, uniform and effective spraying of the plastic parts of the car air conditioning vent, improving the spraying effect and efficiency of the plastic parts of the car air conditioning vent.
[0023] 4. After spraying, the hot air is introduced into the spray box through the air outlet pipe by starting the hot air blower, thereby drying the plastic parts of the car air conditioning vent. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1 - Figure 4The present invention provides a coating device for plastic parts of an automotive air conditioning vent, comprising a coating box 1 and a door 2 rotatably connected to its front side wall. A receiving box 20 is placed on the inner bottom surface of the coating box 1. Sliding rods 3 are slidably installed on both the left and right side walls of the coating box 1, and mounting plates 4 are fixedly installed on the inner ends of the two sliding rods 3. Mounting shafts 5 are slidably installed on the two mounting plates 4, and clamping plates 6 are fixedly installed on the inner ends of the mounting shafts 5. Anti-slip pads are installed on the inner side of the clamping plates 6 to ensure the stability of clamping the plastic parts of the automotive air conditioning vent and to provide protection. A material box 7 is fixedly installed on the top surface of the coating box 1, and the lower end of the side wall of the material box 7 is fixedly connected to the inlet end of a material pump 8 fixedly installed on the top surface of the coating box 1. The outlet end of the material pump 8 is fixedly connected to one end of a conveying pipe 9, and the conveying pipe 9 is fixedly connected through the center of the top of the coating box 1. A nozzle 10 is fixedly installed on the other end of the conveying pipe 9.
[0031] A hot air blower 11 is fixedly installed on the top surface of the spraying box 1, and an air outlet pipe 12 is fixedly installed at the air outlet end of the hot air blower 11. The air outlet pipe 12 is fixedly installed through the top of the spraying box 1. A temperature detector is installed inside the spraying box 1 to monitor the internal temperature, and a PLC control system is installed to control the opening and closing of the hot air blower 11 according to the real-time temperature, so as to ensure effective drying of the plastic parts of the car air conditioning vent after spraying.
[0032] A box body 13 is fixedly installed on the rear side of the spray box 1, and threaded rods 14 are installed on the left and right inner walls of the box body 13. A connecting plate 15 is sleeved on the outer side of the threaded rod 14, and the threaded rod 14 is threadedly connected to the connecting plate 15. The connecting plate 15 slides through the side wall of the box body 13, and a movable plate 16 is fixedly installed on the outer end of the connecting plate 15. The inner side of the movable plate 16 is fixedly connected to the outer end of the slide rod 3.
[0033] A dual-axis motor 17 is fixedly installed on the rear inner wall of the housing 13, and the shaft end of the dual-axis motor 17 is keyed to the inner end of the threaded rod 14.
[0034] A housing 18 is fixedly mounted on the outer side of one side mounting plate 4, and a drive motor 19 is fixedly mounted on the inner wall of the housing 18, and the shaft end of the drive motor 19 is keyed to the outer end of the mounting shaft 5.
[0035] Working principle: When in use, the dual-axis motor 17 is started to drive the threaded rod 14 to rotate. When the threaded rod 14 rotates, the connecting plate 15 connected to it by the thread can only move along the axial direction of the threaded rod 14 under the restriction of the side wall of the housing 13. The connecting plate 15 drives the slide rod 3 and the mounting plate 4 to move synchronously through the moving plate 16, which in turn drives the mounting shaft 5 and the clamping plate 6 to move, so as to clamp and fix the plastic parts of the car air conditioning vent placed between the clamping plates 6. The anti-slip pad on the inner side of the clamping plate 6 can enhance stability and protect the plastic parts.
[0036] The material pump 8 starts, extracts the paint from the material tank 7, and transports it to the nozzle 10 through the material conveying pipe 9. The nozzle 10 sprays the paint onto the fixed plastic parts of the car air conditioning vent, thus realizing the spraying process of the plastic parts of the car air conditioning vent.
[0037] The drive motor 19 starts and drives the mounting shaft 5 to rotate. The mounting shaft 5 then drives the clamping plate 6 and the clamped plastic part to rotate synchronously. During the rotation of the plastic part, the spray nozzle 10 continuously sprays, thereby achieving comprehensive and uniform spraying of the plastic part from different angles, improving the spraying quality and effect.
[0038] After the spraying is completed, the hot air blower 11 is started, and the generated hot air enters the spraying box 1 through the air outlet 12. The temperature detector in the spraying box 1 monitors the temperature in real time and feeds the data back to the PLC control system. The PLC control system controls the opening and closing of the hot air blower 11 according to the set temperature range to ensure effective drying of the sprayed plastic parts and accelerate the production process.
[0039] Throughout the spraying process, the dripping paint will fall into the collection box 20 placed on the bottom of the spraying box 1, which facilitates subsequent cleaning and recycling, keeps the inside of the spraying box 1 clean, and saves production costs. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
