DETAILED DESCRIPTION

[0021] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0022] like Figures 1-4 As shown, this embodiment provides a spraying device for preparing a corrosion-resistant aluminum layer protective film, including a movable frame 1, a spraying component 2, a pressure roller 3 and a drying component.

[0023] The movable frame 1 includes a transverse portion 11 and a vertical portion 12. The vertical portion 12 is connected to the upper surface of one side of the transverse portion 11. The transverse portion 11 and the vertical portion 12 are interconnected. The transverse portion 11 includes a spray chamber 111, a film pressing chamber 112 and a drying chamber 113 from left to right. The vertical portion 12 has a material cavity 121, and a clearance gap is formed on one side of the vertical portion 12 corresponding to the spray assembly 2. Sliding grooves 115 are formed on the lower surface of both sides of the transverse portion 11. A movable seat 116 is arranged in the sliding groove 115. The movable seat 116 is provided with a threaded hole therethrough. Two screws are arranged on the external device. The two screws pass through the threaded holes respectively. The movement of the movable frame 1 is controlled by rotating the screws.

[0024] The spraying assembly 2 includes a transverse mounting plate 21 and a sprayer 22. A plurality of sprayers 22 are sequentially arranged on the lower surface of the transverse mounting plate 21, and the sprayers 22 are located in the transverse portion 11. Specifically, a storage cavity 211 is formed in the transverse mounting plate 21, and the storage cavity 211 is connected to the spraying chamber 111 of the sprayer 22. A material pipe is formed above the clearance gap, and the material pipe passes through the clearance gap and is connected to the transversely mounted storage cavity 211.

[0025] The horizontal mounting plate 21 is detachably connected to the vertical portion 12, and the spraying machine 22 is communicated with the material cavity 121. Specifically, sliding notches 122 are formed on the inner sides of both ends of the vertical portion 12. One opening of the sliding notch 122 is located on the side surface of the vertical portion 12, and the other opening of the sliding notch 122 is located on the inner surface of the vertical portion 12 facing inward. The horizontal mounting plate 21 is located in the sliding notch 122, and a top limiting component is arranged between the horizontal mounting plate 21 and the sliding notch 122. The top limiting component includes two top blocks 212 and a screwing-in column 213. Through holes 214 penetrating up and down are formed on both sides of the horizontal mounting plate 21, and a second through hole 215 is formed on the surface of the horizontal mounting plate 21. The second through hole 215 is communicated with the first through hole 214. The connection part of the second through hole 215 and the first through hole 214 is the middle part of the first through hole 214. The top blocks 212 are located in the first through hole 214 and on the upper side and the lower side of the second through hole 215. A flexible block 2122 is bonded to the outer surface of the top block 212, making the top more fitting. Two annular limiting grooves 2141 are formed in the first through hole 214. Limiting rings 2121 are formed on the circumferences of the two top blocks 212. The limiting rings 2121 are located in the annular limiting grooves 2141. The length of the annular limiting groove 2141 is greater than the thickness of the limiting ring 2121. The screwing-in column 213 is located in the second through hole 215. The circumferential surface of the screwing-in column 213 located in the second through hole 215 is an inclined surface gradually sloping downward inward. A flat protruding plate is formed on the outer surface of the screwing-in column 213, which is convenient for manual holding and rotation.

[0026] When the horizontal mounting plate 21 is in an unlocked state, the two top blocks 212 are located in the first through hole 214. When the horizontal mounting plate 21 moves to the installation position, manually rotate the flat protruding plate, and the screwing-in column 213 moves inward. The lower surface of the top column moves upward as the screwing-in column 213 moves inward, and the opening extending out of the first through hole 214 abuts against the upper and lower side walls of the sliding notch 122. At this time, the horizontal mounting plate 21 is limited.

[0027] The pressing roller 3 and the drying component are respectively located in the film pressing chamber 112 and the drying chamber 113. There is a partition 114 between the film pressing chamber 112 and the drying chamber 113. The drying chamber 113 includes a plurality of cooling fans 4, and the plurality of cooling fans 4 are arranged at intervals.

[0028] Working principle: The moving frame 1 moves to the designated position, and the film to be processed passes under the moving frame 1. First, it passes through the spraying chamber 111. The spraying machine 22 in the spraying chamber 111 sprays on the surface of the film to be processed. After spraying, the film to be processed passes through the pressing roller 3 for pressing and thickness fixing, and finally passes through the drying chamber 113 and is cooled and shaped by the cooling fan 4. When it is found that the spraying at a certain place on the film to be processed is uneven or not sprayed in place after spraying, the moving frame 1 moves, so that the spraying assembly 2 moves above the target position for re-spraying, then is re-pressed and thickness-fixed by the pressing roller 3, and finally is dried by the drying assembly, with a high degree of intelligence.
