[0001] The utility model relates to the technical field of spraying devices, in particular to a thin film coating spraying device. Background Art

[0002] Thin film coating spraying is a common surface coating technology, usually used to add specific properties to the material surface, such as wear resistance, corrosion resistance, optical properties, etc.

[0003] After searching, the authorization announcement number CN220160321 U discloses a thin film coating spraying device, which belongs to the technical field of spraying devices, including: a frame; the frame is provided with an inlet and an outlet, and a spraying chamber and a drying chamber are arranged inside; a spraying mechanism is arranged in the spraying chamber; the spraying mechanism includes a fixed block, a sliding rod, a slider, and a nozzle; the number of the fixed blocks is two, which are respectively arranged on the two inner sides of the frame; the two ends of the sliding rod are respectively fixed to the two fixed blocks; the slider is a plurality of blocks, which are driven by a moving mechanism to slide on the sliding rod; the nozzle is fixed on the slider, with the bottom facing the film and the top connected to the paint source. The nozzle of the above technical solution can be controlled to move by the moving mechanism, and the spraying range can be adjusted to meet the spraying needs of films of different widths, thereby improving the applicability and flexibility of the spraying device.

[0004] In the above technical solution: the spraying width of the entire spraying device is adjusted by adjusting the distance between two adjacent groups of nozzles, thereby realizing the spraying needs of films of different widths. However, after adjusting the distance between the two adjacent groups of nozzles, the spraying intensity of the nozzles needs to be adjusted accordingly, otherwise the film cannot be fully sprayed, and the position between the two groups of nozzles will not be sprayed with paint. The position of the nozzle is fixed, resulting in incomplete spraying and the inability to automatically control the spraying width.

[0005] To this end, we propose a thin film coating spraying device. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: A thin film coating spraying device, such as Figures 1-4 As shown, it includes two groups of support frames 1 distributed in a left and right mirror image, and the support frames 1 are provided with mounting ears 2. A hollow beam 3 is fixedly installed between the two groups of support frames 1. Multiple groups of fixing rods 5 are fixedly installed inside the hollow beam 3. A spray assembly 6 for spraying the film is provided on the hollow beam 3;

[0029] Furthermore, the spraying assembly 6 includes a paint box 601 and a sprayer 603. A moving block 602 is fixedly installed on the bottom surface of the paint box 601, and the sprayer 603 is fixedly installed on the side of the moving block 602 away from the paint box 601. A nozzle 605 is provided on the bottom surface of the sprayer 603, and a delivery pipe 606 connected to the external paint tank is provided on the top surface of the paint box 601. A plurality of groups of connecting ports are provided on the moving block 602, and the moving block 602 is slidably installed on the plurality of fixed rods 5 through the connecting ports. A threaded sleeve 604 is provided on the moving block 602, and a screw rod 7 is provided inside the hollow beam 3. A blank section 700 is provided in the middle section of the screw rod 7. Threaded sections 701 are provided on the left and right sides of the blank section 700 on the screw rod 7, and the thread directions of the threaded sections 701 on both sides are oppositely arranged. The moving block 602 is installed on the screw rod 7 through the matching threads of the threaded sleeve 604 and the threaded section 701.

[0030] Among them, a group of support frames 1 are provided with a motor box 8 on the outer side, a driving motor is provided in the motor box 8 and the output end of the driving motor is fixedly connected to the screw rod 7. The screw rod 7 is controlled to rotate forward or reverse by the driving motor in the motor box 8, so that the screw rod 7 controls the spray assembly 6 to slide left and right in the hollow beam 3 through the threaded sleeve 604, so that the two groups of spray assemblies 6 are close to or away from each other in the hollow beam 3. When in use, the hollow beam 3 is controlled to be installed on the spraying operating table, and the film slowly passes through the hollow beam 3 under the action of external traction. By controlling the two groups of spray assemblies 6 to reciprocate and approach and move away from each other, the nozzle 605 sprays the paint evenly on the film.

[0031] Example 2, based on Example 1, two groups of limit slider frames 4 are slidably installed on the hollow beam 3, and the limit slider frames 4 are distributed on the side of the two groups of spraying components 6 facing away from each other. The bottom surface of the limit slider frame 4 is provided with an infrared irradiation light strip 401, and the side of the limit slider frame 4 close to the spraying component 6 is provided with an information sending button 400 for controlling the driving motor in the motor box 8. When the width of the film to be sprayed is different, the hollow beam 3 is controlled to be installed and fixed on the spraying operating table, and the two groups of limit slider frames 4 on the hollow beam 3 are slid so that the spacing between the two groups of limit slider frames 4 is the same as the width of the film, and the infrared irradiation light strip is used. 401 emits an infrared reference line vertically downward to facilitate accurate positioning of the position of the limit slider frame 4. After the positions of the two groups of limit slider frames 4 are adjusted, the two groups of spray components 6 are controlled to move back and forth towards and away from each other, so that the moving range of the two groups of spray components 6 is controlled between the two groups of limit slider frames 4, which is convenient for spraying a film of a specified width. When the spray component 6 is close to and fits into the limit slider frame 4, the spray component 6 will touch the information sending button 400, and the information sending button 400 will transmit the signal to the drive motor in the motor box 8, thereby controlling the rotation direction of the drive motor in the motor box 8, and facilitating the control of the forward and reverse rotation of the screw rod 7.

[0032] The working principle of this utility model:

[0033] When the width of the film to be sprayed is different, the hollow beam 3 is controlled to be installed and fixed on the spraying operating table, and the two groups of limit slider frames 4 on the hollow beam 3 are slid so that the spacing between the two groups of limit slider frames 4 is the same as the width of the film. The infrared reference line is sent vertically downward by the infrared irradiation light bar 401, which is convenient for accurately positioning the position of the limit slider frame 4. After the positions of the two groups of limit slider frames 4 are adjusted, the two groups of spraying components 6 are controlled to move back and forth towards and away from each other, so that the moving range of the two groups of spraying components 6 is controlled between the two groups of limit slider frames 4, which is convenient for spraying films of specified widths. When the spraying component 6 is close to and fits into the limit slider frame 4, the spraying component 6 will touch the information sending button 400, and the information sending button 400 will transmit the signal to the driving motor in the motor box 8, thereby controlling the rotation direction of the driving motor in the motor box 8, which is convenient for controlling the forward and reverse rotation of the screw rod 7.

[0034] The motor in the motor box 8 is used to drive the screw 7 to rotate forward or reverse, so that the screw 7 controls the spray assembly 6 to slide left and right in the hollow beam 3 through the threaded sleeve 604, so that the two groups of spray assemblies 6 are close to or away from each other in the hollow beam 3. When in use, the hollow beam 3 is controlled to be installed on the spraying operation table. The film slowly passes through the hollow beam 3 under the action of external traction. By controlling the two groups of spray assemblies 6 to reciprocate and move closer to and away from each other, the nozzle 605 sprays the paint evenly on the film.
