[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the printing industry, various surface laminating devices and technologies are used to meet the laminating needs of printed materials of different materials. These include: 1. Traditional thermal laminating machines: Traditional thermal laminating machines mainly use roller heating. Through the contact and rotation of the roller and the film, the heat energy is transferred to the film to achieve the softening and covering effect of the film. 2. Liquid coating technology: Liquid coating technology is to evenly apply the coating or resin material on the surface of the printed matter to form a thin film. This method is suitable for some printed matters that require special textures or effects, but it takes a long time to dry. 3. UV light curing technology: UV light curing technology uses ultraviolet light beams for rapid curing during the laminating process to achieve rapid lamination and efficient production. This technology is fast, energy-saving and environmentally friendly, suitable for various types of printed surface lamination, and can achieve high-quality lamination effects. Through continuous innovation and technological progress, printed surface laminating devices are constantly being improved and developed to meet the market's demand for the appearance, durability and quality of printed matters. Different laminating technologies and devices can be selected according to the material, specifications and requirements of the printed matter to achieve the best lamination effect and production efficiency.

Under the action of a first group of laminating mechanisms 4, a film-releasing roller 1 3 is used to laminate the surface of the printed matter. Under the action of a second group of laminating mechanisms 4, a film-releasing roller 2 5 is used to laminate the bottom surface of the printed matter. The double sides of the printed matter can be laminated at one time, which reduces the production process and technology and improves the production efficiency. The utility model comprises a frame 1.

The film-releasing roller 1 3 is located above the material-releasing roller 2, the film-releasing roller 2 5 is located on one side of the material-releasing roller 2, and the material-collecting roller 6 is located at the inner side of the frame 1. Above the film-releasing roller 2 5, a pressing mechanism 4 for pressing the front and back sides of the printed matter is arranged between the film-releasing roller 2 and the film-releasing roller 2 5. There are two groups of pressing mechanisms 4 which are arranged horizontally and vertically, and a driving mechanism 7 is arranged at one end of the receiving roller 6. A dust blowing mechanism 8 for avoiding the generation of bubbles is also arranged in the frame 1. The printed matter is released from the film-releasing roller 2, and under the action of the first group of pressing mechanisms 4, the surface of the printed matter is laminated by the film-releasing roller 1 3, and under the action of the second group of pressing mechanisms 4, the bottom surface of the printed matter is laminated by the film-releasing roller 2 5. The printed matter after double-sided lamination can be finally rolled up by the receiving roller 6.

[0028] To better fit the film on the printed matter, please refer to Figure 2 The laminating mechanism 4 includes a fixed roller 41 rotatably connected to the inner side of the frame 1, a movable roller 42 is provided above the fixed roller 41, and the movable roller 42 is rotatably connected between two tensioning assemblies 43.

[0029] To adjust the pressure applied by the movable roller 42, please refer to Figure 4 The tensioning assembly 43 includes a slider 431, which is slidably arranged in a sliding hole opened on the side wall of the frame 1. A spring 432 is fixedly connected to the slider 431, and a pressure plate 433 is fixedly connected to the top of the spring 432.

[0030] In order to make the receiving roller 6 rotate and perform the winding operation, please refer to Figure 3. The driving mechanism 7 includes a motor 71 installed on the side wall of the frame 1. A gear 1 72 is fixed on the output shaft of the motor 71. The gear 1 72 is meshed with the gear 2 73.

[0032] Embodiment 2:

[0033] When there is dust on the printed matter, bubbles will be generated at the location of the dust after lamination, thus affecting the appearance.

[0034] In order to achieve a better dust blowing effect, the air outlet 84 is tilted to face the direction of movement of the printed matter; in this way, the airflow can better blow the dust off.

[0035] It can be known from the above embodiments that the printed matter is released from the unwinding roller 2, and the surface of the printed matter is coated by the unwinding roller 1 3 under the action of the first group of laminating mechanisms 4, and the bottom surface of the printed matter is coated by the unwinding roller 2 5 under the action of the second group of laminating mechanisms 4. During the coating, the tensioning assembly 43 is used to apply pressure to the movable roller 42. When the printed matter and the film pass between the movable roller 42 and the fixed roller 41, an extrusion effect can be formed on them, so that the two are better fitted. The printed matter after double-sided lamination is finally wound up by the receiving roller 6. During the winding, the motor 71 is used to drive and the receiving roller 6 is driven to rotate under the meshing action of the gear 1 72 and the gear 2 73.
