Description

Technical Field

[0001] This utility model relates to a mobile film-coating roller device. Background Technology

[0002] Currently, in extrusion production lines, the sheets extruded from the mold need to be calendered by a three-roll forming machine and then sent to a cooling tray for cooling. The cooling tray is usually equipped with a film-coating device for pressing and bonding a protective film onto the surface of the sheet. For example, a PEEK sheet production line disclosed in Chinese Patent No. CN221187433U has a film-coating device installed on the cooling tray.

[0003] The laminating apparatus includes a pressure roller assembly, which has an upper pressure roller for pressing and bonding the protective film to the upper surface of the board and a lower pressure roller for pressing and bonding the protective film to the lower surface of the board. The position of the pressure roller assembly on the cooling support directly affects the laminating quality. For example, if the pressure roller assembly is positioned too far forward, the temperature of the board will be too high during lamination, causing the protective film to soften excessively due to the high temperature, resulting in deformation or even localized melting and damage. Conversely, if the pressure roller assembly is positioned too far back, the temperature of the board will be too low during lamination, resulting in the adhesive on the protective film not being fully activated, leading to poor flowability and insufficient adhesion between the protective film and the board. Therefore, the laminating quality is affected by the temperature of the board. In actual production, due to different production processes, different types of boards will have different temperatures when they reach the same position. Therefore, in actual production, it is necessary to adjust the position of the pressure roller assembly to find a suitable lamination position to press the protective film onto the board in order to ensure the quality of lamination. However, in the prior art, the pressure roller device is usually fixedly installed on the cooling bracket. When adjusting the front and rear position of the pressure roller device, it is necessary to first disassemble the pressure roller device and then reinstall it in the new position. This makes the operation of adjusting the position of the pressure roller device very complicated and troublesome, which in turn leads to low position adjustment efficiency. Utility Model Content

During the movement of the sheet 5, the upper pressure roller 2 presses and adheres the protective film 9 to the upper surface of the sheet 5, and the lower pressure roller 3 presses and adheres the protective film 9 to the lower surface of the sheet 5. When the position of the movable coating roller device of this embodiment needs to be adjusted, firstly, the upper drive assembly drives the upper lifting seat to move upward, thereby moving the upper roller 2 upward to its position. The lower drive assembly drives the lower lifting seat to move downward, thereby moving the lower roller 3 downward to its position. Then, the traveling drive mechanism drives the mounting frame 1 to move back and forth on the cooling bracket 4 to its position. Then, the upper drive assembly drives the upper lifting seat to move downward, thereby moving the upper roller 2 downward to press the protective film 9 onto the upper surface of the board 5. The lower drive assembly drives the lower lifting seat to move upward, thereby moving the lower roller 3 upward to press the protective film 9 onto the lower surface of the board 5. At this time, as the board 5 moves, the upper roller 2 can again press and adhere the protective film 9 onto the upper surface of the board 5, and the lower roller 3 can again press and adhere the protective film 9 onto the lower surface of the board 5. The movable coating roller device of this embodiment can conveniently and quickly adjust its position on the cooling bracket 4, greatly improving the convenience and efficiency of position adjustment, and making it more convenient to use.
