[0002] Laminating machines are mainly used to produce transfer paper products and perform surface coating on semi-finished products. Under the current diversified and distinctive competition concept, single paper products lack industry competitiveness and cannot meet customers' special product requirements. Therefore, making good laminating products that combine paper and film is a necessary requirement for the development of the industry. Laminating refers to the use of a laminating machine to apply a transparent plastic film to the surface of paper prints to protect and increase the gloss. It has been widely used in the surface binding and protection of book covers, picture albums, commemorative albums, postcards, product manuals, calendars and maps.

[0003] However, when the laminating machine produces laminated products, affected by factors such as unstable tension, unstable speed, unstable deviation correction, unstable air pressure, etc., the tension of paper and film in the laminating machine production process is unbalanced, which will cause local deformation of paper and film materials, and easily produce film wrinkles, bubbles and other undesirable phenomena, resulting in uneven laminated products after lamination, affecting the quality of the laminated products.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower" and "both sides" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second" and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0019] like Figure 1 As shown, the utility model is a tension balancing device for a compound machine, which is applied to a compound machine with a feed roller group 1 and a laminating roller group 2. Other structures and components of the compound machine and a PLC control system all adopt existing technologies, which will not be described in detail.

[0020] like Figure 2 and Figure 3 As shown, in the first preferred embodiment, two vertical plates 3 are arranged opposite to each other between the feed roller group 1 and the laminating roller group 2 of the compound machine, and the two vertical plates 3 are fixedly connected to the horizontal plate 4 at both ends. Two upper and lower limit slides 301 are arranged on the inner walls of the opposite sides of the two vertical plates 3, that is, one limit slide 301 on the upper part of the vertical plate 3 corresponds to the limit slide 301 on the upper part of the other vertical plate 3, and one limit slide 301 on the lower part of the vertical plate 3 corresponds to the limit slide 301 on the lower part of the other vertical plate 3. Each limit slide 301 is slidably connected to an adjustment component 8, and each adjustment component 8 is connected to the horizontal plate 4. The adjustment component 8 includes a fixed slider 801, and the end of the fixed slider 801 away from the limit slide 301 is fixedly connected to a tension sensor 7, and the first balance roller 5 is rotatably connected between the two upper tension sensors 7. In this embodiment, the tension sensor 7 is a through-axis tension sensor, which can monitor the tension on the first balance roller 5 in real time.

[0021] A second balancing roller 6 with the same structure is arranged below the first balancing roller 5. Both ends of the second balancing roller 6 are also connected with a tension sensor 7 and an adjusting component 8. The first balancing roller 5 and the second balancing roller 6 respectively adjust the tension of the paper and the film. According to the tension value monitored by the tension sensor 7, the adjusting component 8 drives the first balancing roller 5 and the second balancing roller 6 to move up and down, so as to adjust the tension of the paper and the film in a balanced manner during the laminating process.

[0022] Specifically, the adjusting component 8 includes a connecting block 802 connected to a hinge 803 at the upper end of a fixed slider 801, and an electric push rod 804 is fixedly connected to the upper end of the connecting block 802 and is hinged to the lower part of the horizontal plate 4. The electric push rods 804 on both sides of the first balancing roller 5 and the second balancing roller 6 are electrically connected to the PLC controller and move synchronously to drive the first balancing roller 5 and the second balancing roller 6 to move up and down.

[0023] During use, when the tension sensor 7 detects that the paper and film tension values ​​on the first balancing roller 5 and the second balancing roller 6 are unbalanced, the PLC controller can start the electric push rod 804 to drive the first balancing roller 5 and the second balancing roller 6 to move up and down, so as to balance and adjust the paper and film tension values.

[0024] like Figure 4 As shown, in the second preferred embodiment, the adjusting component 8 includes an adjusting screw 805 rotatably connected to the upper end of the fixed slider 801, and the adjusting screw 805 penetrates and is threadedly connected to the cross plate 4. When the tension sensor 7 detects that the paper and film tension values ​​on the first balancing roller 5 and the second balancing roller 6 are unbalanced, the two adjusting screws 805 can be screwed at the same time to drive the first balancing roller 5 and the second balancing roller 6 to move up and down, so as to balance and adjust the paper and film tension values.

[0025] In the above embodiment, the fixed slider 801 slides in the limiting slide groove 301 and extends to the outside of the limiting slide groove 301 to facilitate the electric push rod 804 or the adjusting screw 805 to perform lifting operations on it.

[0026] The preferred specific implementation modes and embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation modes and embodiments, and various changes or equivalent substitutions can be made within the knowledge scope of those skilled in the art without departing from the concept of the utility model. Therefore, the utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the utility model.
