Description

Technical Field

[0001] This utility model belongs to the field of LED tube coating technology, and more specifically, it relates to a dual-color film coating device for LED tubes. Background Technology

[0002] In the LED lighting industry, as people's requirements for the appearance and function of lamps continue to increase, LED tubes with dual-color effects are becoming increasingly popular in the market. During the processing and production of dual-color LED tubes, a dual-color film coating device is needed to coat the surface of the LED tube with a dual-color film, thus creating the dual-color effect. Existing dual-color film coating devices for LED tubes mainly rely on a roller system to transport the dual-color film. The dual-color film is usually mounted in rolls on a film roll support. As the LED tube is rotated at a constant speed by a rotating mechanism, the dual-color film transported by the rollers gradually and tightly wraps around the surface of the LED tube, forming the coating.

[0003] Existing application number CN201922348670.3 discloses a fixed-length cutting and coating device for LED tubes, including a traction device and a cutting machine located behind the traction device. A support frame is provided behind the traction device, and a slide rail along the tube output direction is provided on the support frame. A sliding trolley is slidably mounted on the slide rail, and the cutting machine controlled by a first cylinder is mounted on the sliding trolley. An extension rod is provided on the sliding trolley along the tube output direction, and a baffle is rotatably connected to the end of the extension rod. A second cylinder with hinged ends is provided between the baffle and the extension rod, and a distance sensor is provided on the baffle. A third cylinder is provided on the extension rod, and a fourth cylinder is provided on the support frame. A coating device is provided in front of the traction device. This fixed-length cutting and coating device can automatically cut and coat LED tubes, saving labor costs, improving the flatness of the cut surface, and automatically coating one side of the LED tube surface to ensure that one side of the LED tube is free of scratches.

[0004] Based on the above, existing dual-color film coating devices for LED tubes may experience conveying deviations and accumulations during the roller conveying process. In some areas, excessive accumulation of dual-color film may cause deformation and wrinkles. Furthermore, when the blade cuts the dual-color film, excessive tension on the film can lead to problems such as curling edges, affecting the subsequent coating effect. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a dual-color film coating device for LED tubes. This addresses the issues that existing dual-color film coating devices for LED tubes may experience conveying deviations or accumulation during roller conveying, resulting in deformation and wrinkles in some areas due to excessive accumulation of the dual-color film. Furthermore, excessive tension on the dual-color film during blade cutting can lead to issues such as curled edges, affecting the subsequent coating effect.

[0006] The purpose and effect of this utility model, a dual-color film coating device for LED tubes, are achieved by the following specific technical means:

[0007] A dual-color film coating device for LED tubes includes a coating device body;

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] First, this utility model has a coating assembly. The rotating chuck drives the LED tube to rotate, and the coating roller flattens the bicolor film covering the LED tube, making the bicolor film adhere more tightly to the surface of the LED tube. The heating strip heats the bicolor film, causing it to shrink and wrap more tightly, which greatly improves the coating effect of the bicolor film.

[0034] Secondly, this utility model has a cutting component that smooths and unfolds the two-color film roll before the cutting blade cuts it by using a smoothing roller, which avoids wrinkles on the surface of the two-color film roll that may affect subsequent processing. It also makes the stress distribution of the two-color film roll uniform and gives it a certain tension. The unfolding and tension can effectively suppress the elastic recovery of the two-color film roll, so it can effectively maintain flatness and reduce edge curling after the two-color film roll is cut.

[0035] This invention has the advantages of tight wrapping, smoothing and unfolding, and reducing edge curling, which greatly improves the coating effect of the two-color film. It also avoids the accumulation of wrinkles on the surface of the two-color film roll that affects subsequent processing, and effectively reduces the amount of two-color film rolls after cutting.
