The device is characterized in that it also includes a cleaning component mounted on the outer side of the drying rack, the cleaning component being in contact with the drying cylinder but not with the composite optical film.

[0008] Specifically, the cleaning component includes a mounting frame, a top block, a bottom block, and a fixing post mounted on the mounting frame to form a U-shaped fixing structure, with the fixing structure provided on both sides. A rubber roller seat and a dust-adhesive seat are fitted onto the fixing post. The dust-adhesive seat is elastically connected to the rubber roller seat by a spring, and the rubber roller seat is elastically connected to the bottom block by a spring. The dust-adhesive roller is movably mounted on the dust-adhesive seat by a motor, and the rubber roller is movably mounted on the rubber roller seat. At the same time, cylinders are symmetrically mounted on the mounting frame, and the cylinders are used to push the dust-adhesive roller to move along the length direction of the fixing post.

[0009] Specifically, the two ends of the top block are connected to the two ends of the bottom block through fixing posts.

[0010] The beneficial effects of this utility model are:

[0011] This device is equipped with a cleaning component, which ensures both the cleaning power within the drying unit, thereby guaranteeing product quality, and also extends the service life of the cleaning component. Attached Figure Description

[0016] like Figures 1-2 As shown, this utility model provides a drying device for a coating machine, including a drying rack 1, a drying cylinder 4 movably mounted on the drying rack via a motor, a plurality of ultraviolet lamps 2 arranged along the tangent direction of the outer circumference of the drying cylinder 4 and mounted on the drying rack 1, a plurality of transition rollers 14 mounted on the drying rack 1, and a cleaning component mounted on the outer side of the drying rack 1. The cleaning component contacts the drying cylinder 4 but does not contact the composite optical film 15, wherein the cleaning component is used to clean the dust adhering to the drying cylinder 4.

[0017] The cleaning assembly includes a mounting frame 3. A top block 8, a bottom block 9, and a fixing post 10 mounted on the mounting frame 3 form a U-shaped fixing structure, with the fixing structure provided on both sides. A rubber roller seat 12 and a dust-adhesive seat 11 are fitted onto the fixing post 10. The dust-adhesive seat 12 is elastically connected to the rubber roller seat 12 via a spring 13. The rubber roller seat 12 is elastically connected to the bottom block 9 via a spring 13. A dust-adhesive roller 6 is movably mounted on the dust-adhesive seat 12 via a motor. A rubber roller 5 is movably mounted on the rubber roller seat 12. At the same time, cylinders 7 are symmetrically mounted on the mounting frame 3. The cylinders 7 are used to push the dust-adhesive roller 6 to move along the length of the fixing post 10, thereby synchronously pushing the rubber roller seat 12 to move.

[0018] Specifically, the two ends of the top block 8 are connected to the two ends of the bottom block 9 through the fixing posts 10, thus forming a square shape.

[0019] The control panel is connected to the communication ground of UV lamp 2, motor 1, motor 2 and cylinder 7.

[0020] The control panel contains a PLC controller, which is a programmable numerical control system. The PLC acts as the central control system, using a touchscreen to input programs and control the entire machine, achieving full automation of the operation. The control system connects various actuators, allowing them to move along logical trajectories. Programming controls allow these actuators to operate according to the required steps.

[0021] The working principle of this utility model is as follows:

[0022] At work, such as Figure 2 As shown, the composite optical film 15 passes sequentially around the drying cylinder 4 and several transition rollers 14, and is dried and cured by the ultraviolet lamp 2. During the operation, the cylinder 7 is activated, which pushes the dust-adhesive roller 6 forward, further pushing the adhesive roller 5 closer to the drying cylinder 4, thereby adhering to the dust or grime present on the drying cylinder 4. Since the composite optical film itself will carry some dust during the entire composite process, the dust will adhere to the drying cylinder 4 when passing through the drying step. In order to ensure the quality of the final product, a cleaning component is provided next to the drying cylinder 4 to clean the drying cylinder 4 and prevent dust from accumulating in the subsequent composite optical film 15. The cleaning component first cleans the drying cylinder 4 with the adhesive roller 5. In order to extend the service life of the cleaning component, the dust-adhesive roller 6 cleans the adhesive roller 5. At the same time, the second motor is activated, which drives the dust-adhesive roller 6 to rotate, and then the dust-adhesive roller 6 drives the adhesive roller 5 to rotate, thereby avoiding cleaning the drying cylinder 4 in the same position all the time and further ensuring the cleaning quality.

[0023] This device is equipped with a cleaning component, which ensures both the cleaning power within the drying unit, thereby guaranteeing product quality, and also extends the service life of the cleaning component.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
