[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-3 This utility model provides an embodiment of a double-roller pressure adjustable cold laminating mechanism, including a laminating machine housing 1 and a control panel 2. The control panel 2 is fixedly connected to the front outer wall of the laminating machine housing 1. By placing the control panel 2 on the front of the housing, it is convenient for operators to intuitively observe and control the equipment parameters, improving operational convenience. The laminating machine body 3 is fixedly connected to the rear inner wall of the laminating machine housing 1, and a motor 4 is fixedly connected to the rear outer wall of the laminating machine housing 1. The motor 4 serves as a power source, providing power for the operation of the equipment and driving the internal rollers to rotate. The laminating process involves the bonding of the film 59 with the substrate. An adjustment mechanism 5 and an auxiliary structure 6 are installed on the laminating machine housing 1. The adjustment mechanism 5 includes a slide rail 51, which is located on the inner walls of the front and rear sides of the laminating machine housing 1. The slide rail 51 is manufactured with high precision, ensuring a straightness error of ≤0.05mm. This provides precise guidance for the sliding plate 53, ensuring its smooth, linear movement during adjustment and preventing deviation that could cause the film 59 to deviate from its conveying trajectory. A guide roller 52 is fixedly connected to the output end of the motor 4 via a coupling. Sliding plates 53 are slidably connected to the inner walls of the left and right sides of the slide rail 51. Auxiliary rollers 54 are rotatably connected to the outer side walls of the sliding plates 53 via bearings. The auxiliary rollers 54 and bearings have a matching precision of P5 level, enabling free rotation with low resistance. Driven by the sliding plates 53, they contact the film 59 with a pressure of 0.1-0.5 MPa, providing support and compression for the film 59, assisting in adjusting the flatness of the film 59, and reducing wrinkles. A compression spring 55 is fixedly connected to the bottom outer wall of the sliding plates 53. The inner walls of the front and rear sides of the laminating machine housing 1 are rotatably connected to the sliding plates 53 via bearings. A pull roller 56 is dynamically connected. The inner walls of the front and rear sides of the laminating machine housing 1 are rotatably connected to a lower pressure roller 57 via bearings. The lower pressure roller 57 is made of rubber with a Shore hardness of 70-80A. It applies downward pressure to the film 59 with a pressure of 0.3-0.8MPa to ensure that the film 59 is fully bonded to the substrate, so that the peel strength after lamination reaches 3-5N / 15mm, thereby improving the tightness and firmness of the lamination. The inner walls of the front and rear sides of the laminating machine housing 1 are rotatably connected to a positioning roller 58 via bearings. The outer side wall of the positioning roller 58 contacts the film 59.
[0024] Reference Figures 2-4The guide roller 52 is rotatably connected to the inner front wall of the laminating machine housing 1 via a bearing. The end of the compression spring 55 away from the sliding plate 53 is fixedly connected to the inner bottom wall of the slide rail 51. The film 59 contacts the outer side wall of the lower pressure roller 57 and the outer side wall of the pull roller 56. When the pull roller 56 contacts the film 59, it uses surface friction (friction coefficient 0.3-0.5) to generate a pulling force on the film 59, effectively stretching the film 59 and eliminating more than 80% of the initial wrinkles on the surface of the film 59. The film 59 contacts the inner bottom wall of the laminating machine body 3, the guide roller 52 contacts the outer side wall of the film 59, and the auxiliary roller 54 contacts the outer side wall of the film 59.
[0025] Reference Figures 3-4 The auxiliary structure 6 includes a limiting port 60, which is located on the inner front wall of the laminating machine housing 1. A housing cover 61 is slidably connected to the inner front and rear walls of the laminating machine housing 1. An adjusting plate 62 is slidably connected to the inner top wall of the housing cover 61. An arc-shaped plate 64 is fixedly connected to the outer front wall of the adjusting plate 62. Anti-blue light glass 63 is fixedly connected to the inner top wall of the housing cover 61. The anti-blue light glass 63 has an ultraviolet blocking rate ≥90% and a visible light transmittance ≥85%. Without affecting the operator's observation of the internal processing status of the equipment, it effectively prevents ultraviolet rays from causing aging, discoloration, and other adverse effects on the film 59 and the laminating process, extending the service life of the film 59 by approximately 30%. An anti-radiation layer is fixedly connected to the inner side wall of the housing cover 61. The anti-radiation layer is made of a special composite material and can shield... More than 95% of external ionizing radiation is used to prevent radiation from causing oxidation, degradation, or cross-linking reactions in the coating material, thus improving the weather resistance of the coating material by 40% and ensuring stable coating quality. The front and rear outer walls of the adjusting plate 62 are fixedly connected with abrasive pads. The surface roughness Ra value of the abrasive pads is 6.3-12.5μm, which increases the friction between the adjusting plate 62 and the operator's hand, making the sliding operation of the adjusting plate 62 more stable and convenient, avoiding slippage, and reducing the operation error rate by about 40%. The arc plate 64 penetrates the front inner wall of the limiting port 60. The left and right inner walls of the coating machine housing 1 are rotatably connected to the rotating rod 65 through bearings. The outer side wall of the rotating rod 65 is fixedly connected to the smoothing plate 66, which can perform simple smoothing treatment on the surface of the coated material, improving the quality and aesthetics of the coated product.
[0026] Working principle: By turning on the motor 4, the guide roller 52 rotates. Simultaneously, under the continuous thrust of the compression spring 55, the sliding plate 53 causes the auxiliary roller 54 to continuously press upward on the bottom surface of the film 59. Then, the guide roller 52 rotates, causing the film 59 and the auxiliary roller 54 to rotate simultaneously, generating a certain pulling force on the film 59 and moving it outward. At the same time, the film 59 is stretched and wrinkle-resistant at the rear end under the continuous pulling force. Meanwhile, the film 59 is pre-pressed by the positioning roller 58 and the lower pressure roller 57. Then, the film 59 is pulled upward by the pull roller 56, so that the surface of the film 59 is stretched and flat when it enters the laminating machine body 3 for processing. Ultraviolet rays or radiation may easily enter the interior of the laminating machine housing 1 in the surrounding environment, causing quality deviations during the laminating process. Therefore, by inserting the housing cover 61 into the inner top wall of the laminating machine housing 1, the radiation shielding layer protects against external radiation that could cause oxidation, degradation, or cross-linking reactions in the laminating material, leading to a decrease in the material's weather resistance and making it more prone to swelling or decomposition when in contact with water or solvents. At the same time, the blue light blocking glass 63 blocks external ultraviolet rays to a certain extent without affecting the visibility of personnel through the internal processing, preventing ultraviolet rays from degrading the laminating material, causing yellowing, decreased transparency, or even surface hardening, cracking, and aging.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
