[0002] With the rapid development of the times, automobiles have become an integral part of life. Currently, with the continuous increase in vehicles, the production technology of automobile parts is also developing more and more rapidly. Automobile plastic parts are generally engineering plastics, which can be used as engineering materials and plastics to replace metals in the manufacture of machine parts.

[0003] Existing automated painting production lines for automotive plastic parts cannot dry the surface of the plastic parts after painting, requiring them to be air-dried for a long time or moved to a drying device, which affects production efficiency and thus lacks practicality. Utility Model Content

[0010] Preferably, multiple air supply ducts are provided.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides an automated spraying production line for automotive plastic parts, which has the following beneficial effects: This invention has the advantage of allowing direct drying after spraying. After spraying, the operator turns on the heating block inside the first tube to heat the inside of the tube. Then, the operator turns on the blower to blow outside air into the first tube for heating. After the hot air enters the second tube, it is sprayed out through two air supply pipes to dry the surface of the automotive plastic parts. The air is then discharged outside the device through the exhaust pipe, thus allowing the automotive plastic parts to be dried in time after spraying, solving the problem that the device cannot dry the parts simultaneously after spraying.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] Example 1 See Figure 1-4An automated spraying production line for automotive plastic parts includes a main component 1; the main component 1 includes a housing 11, with a rotating door 12 hinged to its front surface; a spraying mechanism 13 disposed on the housing 11; a drying component 2 disposed on the housing 11, the drying component 2 including: a first pipe 21 inserted into the top of the housing 11; a blower 22 fixedly connected to the top of the housing 11, with its output end inserted into the inside of the first pipe 21; a heating block 23 fixedly connected to the inner wall of the first pipe 21; a second pipe 24 fixedly connected to the outer wall of the first pipe 21; two air supply pipes 25 inserted into the outer wall of the second pipe 24; and an air outlet pipe 26 inserted into the outer wall of the housing 11; a filter screen 4 disposed on the blower 22; and a temperature sensor 6 disposed on the inner wall of the housing 11, the temperature sensor 6 being electrically connected to the heating block 23.

[0016] When ready for use, the operator places the housing 11 in the designated position. The operator then opens the rotating door 12 to place the automotive plastic parts into the housing 11, allowing them to be sprayed by the spraying mechanism 13. After spraying, the operator activates the heating block 23 inside the first pipe 21, allowing the heating block 23 to heat the inside of the first pipe 21. The operator then turns on the blower 22, which blows external air into the first pipe 21 for heating. The hot air then enters the second pipe 24 and is sprayed out through two air ducts 25 to dry the surface of the automotive plastic parts. The air duct 26 exhausts the air outside the device, allowing the automotive plastic parts to be dried promptly after spraying, thus improving the production efficiency of the device. A filter 4 is installed on the air inlet of the blower 22 to filter the outside air and prevent fine dust and other debris from being blown onto the surface of the automotive plastic parts, affecting the production quality. When the internal temperature of the housing 11 reaches the temperature set by the temperature sensor 6, the temperature sensor 6 transmits an electrical signal to the controller, which then transmits the electrical signal to the heating block 23. Subsequently, the heating block 23 automatically shuts off to prevent overheating inside the housing 11 and damage to the automotive plastic parts, thereby improving the safety of the device.

[0017] Example 2 See Figure 1-4 Based on Embodiment 1, auxiliary functions have been added; The housing 11 is provided with an auxiliary component 3, which includes: a cooling box 31, which is fixedly connected to the outer wall of the housing 11; a pipe body 32, which is fixedly connected to one end of the air outlet pipe 26 and inserted into the inside of the cooling box 31; a one-way valve 5 is provided on the pipe body 32; and multiple air supply pipes 25 are provided.

[0018] During operation, when hot air is discharged through the air outlet 26, it enters the tube body 32 through the air outlet 26. At this time, the cooling water in the cooling box 31 can cool the tube body 32, thereby cooling the hot air in the tube body 32 through heat transfer, preventing the hot air from being blown out directly and scalding the operator when they are nearby, thus improving the safety of the device. The one-way valve 5 on the tube body 32 can prevent the water in the cooling box 31 from flowing back into the tube body 32 and then into the air outlet 26, thereby improving the stability of the device. Multiple air supply pipes 25 can increase the drying area of ​​the device and further improve the drying efficiency of the device.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
