A motor 23 is arranged below the support frame 11, and the motor 23 is responsible for providing power for the entire system, and it is connected to one of the rollers 21. When the motor 23 is started, the powerful power will be continuously transmitted to the rollers 21 connected thereto, so that they start to rotate at high speed. As this group of rollers 21 rotates, through the transmission action of the transmission belt 22, the other rollers 21 will also be driven to form a continuous transmission system. The substrate placed on the roller 21 can move forward smoothly and quickly along the set path under the drive of the motor 23 and the roller 21. Not only the automatic transportation of the substrate is realized, but also the speed and direction of the transportation can be controlled to ensure that the substrate can reach each processing link accurately. Whether in the spray chamber or the drying chamber, the cooperation of the roller 21 and the transmission belt 22 can ensure the high efficiency and stability of the substrate transportation, and provide a guarantee for the smooth progress of the entire production process. At the same time, the control of the motor 23 also enables the entire system to be flexibly adjusted according to different production needs, meet the requirements of various complex processes, and show adaptability and practicality. A first protective cover 31 and a second protective cover 32 are arranged above the support frame 11, and these two protective covers are connected to the support frame 11, so that the upper area of ​​the support frame 11 forms two spray chambers and a drying chamber. A plurality of spraying components are arranged in the spray chamber, and the required coating can be sprayed evenly and carefully on the substrate to achieve the processing of the substrate. A hot air blower 24 is also provided below the support frame 11. The hot air blower 24 is constantly running to generate a continuous flow of hot air. The hot air is connected to the drying chamber through a special connecting pipe, so that the heat generated by the hot air blower 24 can smoothly enter the drying chamber, thereby providing a suitable temperature environment for the substrate in the drying chamber, so as to promote the rapid drying of the coating on its surface and achieve the desired effect.

[0025] like Figures 2 to 4As shown, the spraying assembly includes a gantry 41, and mounting plates 42 are provided at both ends of the gantry 41, and mounting holes are provided on the mounting plates 42 and the support frame 11.
