Description

Technical Field

[0001] The utility model mainly relates to the technical field related to profile lamination, in particular to a lamination device. Background Art

[0002] In the transportation industry, box trucks are a very common type of transportation vehicle. Two or more cargo box panels of box trucks need to be connected by connectors. Our company has designed a connector structure for connecting box panels, which is mainly composed of a cover plate and a cap plate. The cover plate and the cap plate are composited and formed. During the production process, the cover plate is formed by a thin plate through roll forming, composite, and conveying to finally form a connector. In the absence of protection, the surface of the final connector will have scratches, which will affect the appearance of the product, and the appearance of the product is easily damaged during transportation. Therefore, it is necessary to coat the upper surface of the plate during the production of the connector to form a protective film on the surface of the plate, thereby avoiding damage to the appearance of the product during production and transportation. The protective film can be directly torn off after the connector is used.

[0003] The general coating structure, on the one hand, cannot meet the needs of continuous production without stopping, and on the other hand, it is easy to generate bubbles during coating, which affects the appearance of the product. Moreover, the replacement procedures of the film collagen material after use are cumbersome. Therefore, it is necessary to design a new coating structure to meet the needs of continuous and high-quality coating. Utility Model Content

[0025] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0026] This embodiment provides a coating device, which is mainly used for coating a protective film adhesive on the surface of a plate.

[0027] refer to Figure 1 , Figure 2 The figure shows a schematic diagram of the relevant structure of the coating device.

[0028] The laminating device mainly includes an L-shaped support plate 3, which is installed in the production line and adopts an L-shaped design. The relevant parts are arranged on the inner side of the vertical plate of the support plate 3. Figure 1 As shown, a first guide wheel 5 is arranged at the front end of the support plate 3. During production, the plate 1 first enters the laminating device through the guidance of the first guide wheel 5. A second guide wheel 6 is arranged at the rear end of the support plate 3 for guiding the rear end of the plate 1. The first guide wheel 5 cooperates with the second guide wheel 6 to allow the plate 1 to pass through the laminating device along a set route. As a preferred solution of this embodiment, both the first guide wheel 5 and the second guide wheel 6 have guide grooves for guiding the plate 1, and the first guide wheel 5 is higher than the second guide wheel 6 so that the plate 1 is tilted and transported downward for laminating operation.

[0029] A film pressing lower wheel 4 is arranged between the first material guide wheel 5 and the second material guide wheel 6. During the conveying process, the plate 1 passes through the upper surface of the film pressing lower wheel 4 and is coated at the film pressing lower wheel 4. A film hanging wheel 9 is arranged on the upper part of the support plate 3. The film glue roller is installed on the film hanging wheel 9. The film glue 2 is guided to the upper part of the film pressing lower wheel 4 by the first film guide roller 10 and the second film guide roller 11, and the film glue 2 is pressed on the upper surface of the plate 1 by the rubber film pressing roller 85 of the pneumatic film pressing assembly 8.

[0030] In the above structure of this embodiment, the specific principle is as follows: the plate 1 is continuously conveyed through the guidance of the first guide wheel 5 and the second guide wheel 6 and passes through the lower film pressing wheel 4, the film glue 2 is introduced into the lower film pressing wheel 4 through the first film guide roller 10 and the second film guide roller 11 and is located on the upper part of the plate 1, and the film glue 2 and the plate 1 are pressed against the lower film pressing wheel 4 through the rubber film pressing roller 85. As the plate 1 is conveyed, the film glue 2 automatically and continuously adheres to the upper surface of the plate 1.

[0031] The above structure is directly used for lamination. Practice has proved that bubbles are easily generated between the film glue 2 and the plate 1. Therefore, in this embodiment, a supporting roller 7 is provided between the lower film pressing wheel 4 and the second guide wheel 6. The seats at both ends of the supporting roller 7 are installed by means of long holes, so that the supporting roller 7 can adjust the height, and then the supporting force of the supporting roller 7 on the plate 1 from the bottom can be adjusted, so that the plate 1 has an upward tensioning force behind the lamination, and combined with the force of the plate 1 at the lower film pressing wheel 4, the plate 1 and the film glue 2 at the film pressing can be made to fit closely through debugging, thereby solving the problem of bubbles.

[0032] As a preferred solution of this embodiment, a diffuse reflection switch can be provided between the first film guide roller 10 and the second film guide roller 11 to detect the film glue 2. If the film glue 2 breaks, a timely warning can be issued.

[0033] In this embodiment, the pneumatic film pressing assembly 8 provided is driven by a cylinder. Through the flipping structure, the rubber film pressing roller 85 can be pressed against the film pressing lower wheel 4. The pneumatic method is convenient for adjusting the pressing force, and after the film glue 2 is used up, the rubber film pressing roller 85 can be lifted to leave operating space for replacing the new film glue 2.

[0034] refer to Figure 3 , Figure 4As shown, the specific structure of the pneumatic film pressing assembly 8 is as follows: it includes a cylinder 82, a cylinder seat 81, a connecting seat 83, a connecting plate 84 and a support shaft 86, wherein the cylinder seat 81 is fixed on the bracket plate 3, one end of the cylinder 82 is hingedly connected to the cylinder seat 81, and the output shaft of the other end is hingedly connected to the connecting seat 83, there are two connecting plates 84, which are arranged in parallel, the connecting seat 83 is connected to the upper part of the connecting plate 84, the rear end of the connecting plate 84 is installed on the support shaft 86 through a bearing, and the other end is provided with a film pressing roller support shaft 87, and the rubber film pressing roller 85 is installed on the film pressing roller support shaft 87 through a bearing 88. When the cylinder 82 moves in a telescopic motion, the connecting plate 84 is driven to flip around the support shaft 86 as the center, thereby driving the rubber film pressing roller 85 to move. During the film laminating process, the rubber film pressing roller 85 is pressed downward onto the film pressing lower wheel 4, and can be lifted up when the film glue is replaced.
