Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automobile wheel hub plastic spray drying device. Background Art

[0002] Auto parts processing is a complex process involving multiple steps and techniques. After the parts are formed, in order to ensure a certain degree of corrosion resistance, wear resistance and aesthetics, the surface needs to be sprayed, chrome-plated, galvanized, nickel-plated and other surface treatments.

[0003] A Chinese patent with the announcement number CN220346409U discloses a sheet metal spraying device with a drying function. It includes a sheet metal spraying box, a drying device is arranged inside the sheet metal spraying box, and the drying device includes a fixed frame, one side of the fixed frame is fixedly connected to the sheet metal spraying box, a protective plate is fixedly connected to the inner wall of the fixed frame, a driving motor is fixedly connected to the inner side of the protective plate, an air intake fan is fixedly connected to the output end of the driving motor, and a plurality of fixed blocks are fixedly connected to the inner wall of the sheet metal spraying box, a heating wire is fixedly connected to the sides of the plurality of fixed blocks close to each other, and a transmission line pipe is fixedly connected to the inner side of the plurality of fixed blocks. The problem that the traditional sheet metal spraying device has a relatively single function, uneven spraying after the sheet metal spraying is completed, and the sheet metal after the spraying cannot be dried will be caused, which will cause the spraying powder to not adhere to the sheet metal and the thickness of the spraying to be uneven.

[0004] As mentioned above, the patent provides a sheet metal spraying device with a drying function. Although it can solve the problem that the traditional sheet metal spraying device has a relatively single function and cannot dry the sheet metal after spraying, it only uses the heating wire to heat and heat up the interior to dry it, which will inevitably lead to uneven internal temperature. The overall drying uniformity needs to be improved. Utility Model Content
