Description

Technical Field

[0001] The utility model relates to the technical field of paper laminating machines, in particular to a film tension compensation device of a paper laminating machine. Background Art

[0002] Paper lamination, also known as laminating, gluing, or film laminating, involves applying a transparent plastic film to the surface of printed materials through heat and pressure to provide waterproof protection and enhance gloss. Laminating is widely used for surface binding and protection on book covers, albums, commemorative albums, postcards, product manuals, calendars, and maps. During laminating machine operation, the protective film is gradually unwound from a roll. Due to the long distance between the laminating machine's film beaming shaft and the pressure roller, the film is difficult to tighten and flatten. This can easily cause wrinkles on the surface of the loaded paper, affecting the laminating quality. To address this issue, we have developed a film tension compensation device for paper laminating machines. Utility Model Content

[0003] To address the above-mentioned issues, the present invention provides a film tension compensation device for a paper laminating machine. This device addresses the problem that, during the laminating machine's operation, the protective film is gradually unwound from the roll. Due to the long distance between the laminating machine's film beam shaft and the pressure roller, the protective film is difficult to stretch and flatten. Consequently, the protective film on the surface of the loaded paper is easily wrinkled during operation, affecting the laminating quality of the paper.

The die roller 13 can press down the protective film, thereby completing the lamination of the paper.

[0020] The support frame 1 is provided with a guide roller 4 on one side close to the fixed plate 2. The guide roller 4 can guide the protective film, so that the tensioning roller 9 can more effectively tension the protective film.

[0021] The lower end of the support frame 1 is provided with a transmission component 15, which can transmit the paper to be coated.

[0022] The transmission assembly 15 includes a support seat 151, which is provided with two support seats 151. The support seat 151 is fixedly connected to the support frame 1, and a transmission roller 152 is provided above the support seat 151. Both ends of the transmission roller 152 are movably connected to the support seat 151. One end of the transmission roller 152 passes through the support seat 151 and is fixedly connected to the first belt pulley 153. The lower end of the support frame 1 is fixedly installed with a first motor 154. A second belt pulley 155 is provided on the rotating shaft of the first motor 154.

[0025] Specifically, in the present invention, when laminating the supporting paper, the protective film on the unwinding roller passes through the guide roller 4, the tensioning roller 9 and the die roller 13 in sequence. When the protective film passes through the tensioning roller 9, the tensioning roller 9 pushes the protective film under the action of the elastic force of the first spring 8, so that the protective film is in a tensioned state. The first motor 154 drives the first belt pulley 153 to rotate, and the second belt pulley 155 and the transmission roller 152 also rotate through the transmission of the first belt 156. The two transmission rollers 152 drive the transmission belt 157 to rotate, so that the transmission belt 157 can carry the paper for transmission, and the protective film and the paper are located at the same time. When the die roller 13 is below, under the action of the elastic force of the second spring 14, the second spring 14 pushes the mounting plate 12, and the die roller 13 is also moved through the transmission of the mounting plate 12.
