Abstract
Description
Technical Field
[0001] The utility model relates to the field of self-adhesive film production, and more specifically, it relates to a double-roller laminating device for self-adhesive films. Background Art
[0002] Self-adhesive film is a composite material composed of a face material, a pressure-sensitive adhesive, and a backing paper. The face material is usually a film such as polyester (PET), polyethylene (PE), polypropylene (PP), etc., which determines the appearance, printing suitability, and weather resistance. For example, PET film has high transparency, high strength, and good temperature resistance, while PE film has good flexibility and tear resistance; the adhesive is generally a pressure-sensitive adhesive such as acrylate, rubber, etc., and its performance determines the adhesiveness, holding adhesiveness, and removability of the self-adhesive film. Permanent adhesives have strong bonding force and are suitable for long-term fixed labels, while removable adhesives can be easily removed without residual glue; the backing paper is commonly glassine paper, kraft paper, etc., which is used to protect the adhesive and is peeled off during use; self-adhesive film has good printing adaptability and can achieve fine pattern and text printing through offset printing, gravure printing, flexographic printing, digital printing, etc. It also has water resistance, chemical corrosion resistance, and dimensional stability, with small dimensional changes under different temperature and humidity conditions, and is widely used in the label field, such as labels for food and beverage, daily chemical products, medicine, electronic and electrical products, etc., for identifying product information, ingredients, shelf life, etc., and is also used in the decoration field.
[0003] Traditional self-adhesive film laminating devices have many problems in practical applications. On the one hand, the existing laminating device has an unreasonable structural design. Usually, there is only a single pressure roller, which cannot well control the laminating flatness of the film and is difficult to meet the laminating requirements of different products for customers, resulting in uneven quality of the laminated products. On the other hand, the traditional device has defects in the control of the unwinding tension. Since the effective synchronization of the pressure roller and the driving roller cannot be achieved, the unwinding tension of the film material during the laminating process is unstable, increasing the laminating difficulty of the film material and prone to problems such as insecure lamination, wrinkles, and bubbles, seriously affecting the product quality and production efficiency.
[0004] At the same time, most traditional laminating devices cannot perform on-line operation with printing machines. After printing is completed, the materials need to be transferred to a separate laminating device for lamination, which not only increases the production process but also easily causes damage, pollution, etc. during the material transfer process, further reducing the production efficiency and product quality.
[0005] Therefore, in order to solve the above technical problems, this application proposes a double-roller laminating device for self-adhesive films. Summary of the Utility Model
[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a double-roller laminating device for self-adhesive films.
[0007] To achieve the above object, the present utility model provides the following technical solutions: A double-roller laminating device for self-adhesive film, including a first pressure roller and a second pressure roller, the second pressure roller is located above the first pressure roller, and pressure adjustment components are installed on both sides of the first pressure roller and the second pressure roller. The two pressure adjustment components on the same side are directly fixed through a connecting plate. When using this device, adjust the pressure adjustment component on the first pressure roller, so that the first pressure roller vertically applies pressure to the power roller. The power roller drives the first pressure roller to rotate synchronously through strong pressure and friction, guides the film to pass under the second pressure roller, and then performs lamination. Then adjust the pressure adjustment component of the second pressure roller to apply pressure to the first pressure roller.
[0008] Preferably, an installation seat for installing it on the power roller of the printing machine is fixedly connected to the pressure adjustment component.
[0009] Preferably, the first pressure roller is a rubber pressure roller and the second pressure roller is a metal pressure roller to improve the use effect of the device.
[0010] Preferably, the pressure adjustment component includes a hollow housing. A screw is threadedly connected to the top end of the hollow housing. A guide rail for the slider to slide is installed on the side of the hollow housing away from the pressure roller. A lifting block is fixedly connected to the surface of the slider. A spring is installed between the bottom of the lifting block and the inner bottom wall of the hollow housing. A vertical through groove is opened on the side of the hollow housing opposite to the pressure roller. One side of the lifting block is fixedly connected to a cross bar that can pass through the vertical through groove. The side end of the cross bar is rotatably connected to an installation rod through a bearing, and is connected to the pressure roller through the installation rod.
[0011] Preferably, a knob for facilitating its rotation is fixedly connected to the head of the screw, which is convenient for the staff to rotate the screw.
[0012] Preferably, the connection between the installation rod and the pressure roller is detachable to reduce the use cost.
[0013] Preferably, installation blocks are fixedly connected to both sides of the first pressure roller and the second pressure roller. A limiting frame for the installation block to insert is fixedly connected to the head of the installation rod. Threaded rods are fixedly connected to both sides of the bottom end of the installation block. Through holes for the threaded rods to pass through are opened at the bottom of the limiting frame. Nuts are threadedly connected to the outer side walls of the threaded rods. The installation method of first limiting and then fixing is convenient for the staff to operate (the installation position can be quickly found).
[0014] Compared with the prior art, the present utility model has the following beneficial effects:
[0015] 1. The utility model can drive the synchronous rotation of two pressure rollers through a power roller. By the synchronism of the two pressure rollers and the power roller, the unwinding tension of the film material is stabilized, the lamination difficulty of the film material is solved, the process is completed online, and the production efficiency is improved, thus solving the three problems mentioned in the background art;
[0016] 2. The spring in the pressure adjustment component of the utility model is used to support the bottom of the lifting block. At the same time, the spring can also use its elasticity to give an upward force to the lifting block, thereby acting on the screw rod to prevent the screw rod from rotating due to the vibration of the printing machine when it does not need to be controlled;
[0017] 3. The installation rod and the pressure roller of the utility model are detachable, so that when a single damage occurs between the pressure adjustment component and the pressure roller, it can be replaced separately to reduce the use cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] As Figures 1-4As shown in the figure, the present utility model provides a double-roller laminating device for self-adhesive film, which includes a first pressing roller 1 and a second pressing roller 2. The second pressing roller 2 is located above the first pressing roller 1. Pressure adjusting components 3 are installed on both sides of the first pressing roller 1 and the second pressing roller 2. The two pressure adjusting components 3 on the same side are directly fixed through a connecting plate 4. When using this device, the pressure adjusting component 3 on the first pressing roller 1 is adjusted, so that the first pressing roller 1 vertically applies pressure to the power roller. The power roller drives the first pressing roller 1 to rotate synchronously through strong pressure and friction, guides the film to pass under the second pressing roller 2, and then performs lamination. Then, the pressure adjusting component 3 of the second pressing roller 2 is adjusted to apply pressure to the first pressing roller 1. The mounting seat 5 for installing it on the power roller of the printing machine is fixedly connected to the pressure adjusting component 3, and this device is assembled on the power roller of the printing machine through the mounting seat 5.
[0025] During use, the pressure adjusting component 3 on the first pressing roller 1 is adjusted, so that the first pressing roller 1 vertically applies pressure to the power roller. The power roller drives the first pressing roller 1 to rotate synchronously through strong pressure and friction, guides the film to pass under the second pressing roller 2, and then performs lamination. Then, the pressure adjusting component 3 of the second pressing roller 2 is adjusted to apply pressure to the first pressing roller 1. When the machine is running, the power roller drives the two pressing rollers to rotate synchronously. Through the synchronism of the two pressing rollers and the power roller, the unwinding tension of the film material is stabilized, the lamination difficulty of the film material is solved, the online completion of this process is realized, and the production efficiency is improved.
[0026] In summary, this device meets the requirements of the online lamination process of the printing machine. The design of its double pressing rollers can realize the lamination of self-adhesive film, and the lamination flatness can be conveniently adjusted and controlled according to the requirements of customer products (that is, the downward pressure of the second pressing roller 2 is adjusted through the pressure adjusting component 3).
[0027] Furthermore, the first pressing roller 1 is a rubber pressing roller, and the second pressing roller 2 is a metal pressing roller. The two pressing rollers are the key components for realizing the lamination of self-adhesive film. The rubber pressing roller has a certain elasticity and can better adapt to films of different thicknesses and product requirements during pressure adjustment; the metal pressing roller has higher hardness and stability, ensuring the accuracy and stability during the lamination process, thereby improving the use effect of the device.
[0028] Moreover, the present utility model also provides a pressure regulating assembly 3 (as long as other pressure regulating assemblies 3 can perform the above-mentioned pressure application function, they are still within the protection scope of the present utility model). The pressure regulating assembly 3 includes a hollow housing 301. A screw rod 302 is threadedly connected to the top end of the hollow housing 301. A guide rail 303 for the sliding of a slider 304 is installed on one side of the hollow housing 301 away from the pressure roller. A lifting block 305 is fixedly connected to the surface of the slider 304. A spring 306 is installed between the bottom of the lifting block 305 and the inner bottom wall of the hollow housing 301. A vertical through groove 307 is formed on one side of the hollow housing 301 opposite to the pressure roller (the first pressure roller 1 and the second pressure roller 2). A cross bar 308 capable of passing through the vertical through groove 307 is fixedly connected to one side of the lifting block 305. The side end of the cross bar 308 is rotatably connected to a mounting rod 309 through a bearing, and is connected to the pressure roller through the mounting rod 309. A knob 310 for facilitating the rotation of the screw rod 302 is fixedly connected to the head of the screw rod 302. During use, by clockwise rotating the rotary knob 310, the screw rod 302 is driven to rotate clockwise. The screw rod 302 moves downward along the hollow housing 301, thereby pressing the lifting block 305 to move downward. The lifting block 305 drives the slider 304 to move downward. The slider 304 slides along the guide rail 303 to maintain the linear movement of the lifting block 305, and at the same time compresses the spring 306. The spring 306 is used to support the bottom of the lifting block 305. At the same time, the spring 306 can also use its elasticity to give an upward force to the lifting block 305, thereby acting on the screw rod 302 to prevent the screw rod 302 from rotating due to the vibration of the printing machine when not being manipulated. The lifting block 305 drives the first pressure roller 1 and the second pressure roller 2 to move downward through the cross bar 308 and the mounting rod 309, thereby achieving the purpose of applying pressure. When the knob 310 is rotated in the reverse direction, the screw rod 302 moves upward along the hollow housing 301, and the elastic force of the spring 306 drives the lifting block 305 to reset upward (it should be noted that the height of the hollow housing 301 is relatively low, and the length of the spring 306 is also relatively short. It is completely achievable to support the lifting block 305 and drive it to rebound over a small distance as long as the parameters of the spring 306 are properly selected. Moreover, the present utility model does not limit the number of springs 306. The hollow housing 301 can be designed to be longer, and multiple springs 306 can be installed between the bottom of the lifting block 305 and the inner bottom wall of the hollow housing 301 to achieve the above-mentioned support and rebound purposes, so that ordinary springs 306 can also be competent).
[0029] Preferably, the mounting rod 309 and the pressing rollers (the first pressing roller 1 and the second pressing roller 2) are detachable. In this way, when a single component between the pressure adjusting assembly 3 and the pressing rollers is damaged, it can be replaced separately to reduce the use cost. The following is the specific detachable structure: Mounting blocks 6 are fixedly connected to both sides of the first pressing roller 1 and the second pressing roller 2. A limiting frame 7 into which the mounting blocks 6 can be inserted is fixedly connected to the head of the mounting rod 309. Threaded rods 8 are fixedly connected to both sides of the bottom end of the mounting block 6. Through holes 9 for the threaded rods 8 to pass through are formed in the bottom of the limiting frame 7. Nuts 10 are threadedly connected to the outer side walls of the threaded rods 8. That is, the mounting blocks 6 on the first pressing roller 1 and the second pressing roller 2 are inserted into the corresponding limiting frames 7 on the mounting rod 309. After the insertion is completed, the threaded rods 8 on the mounting blocks 6 pass through the through holes 9 on the limiting frames 7. Then, the nuts 10 are rotated clockwise to install the nuts 10 on the screw rods 302. The nuts 10 move upward along the screw rods 302 and gradually abut against the bottom end of the limiting frame 7, thereby fixing the mounting blocks 6 on the limiting frames 7, and also fixing the pressing rollers and the mounting rod 309. Conversely, removing the nuts 10 and then pulling out the mounting blocks 6 from the limiting frames 7 can achieve the disassembly between the pressing rollers and the mounting rod 309.
[0030] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form; any ordinary technician in the industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and described above; however, any equivalent changes, such as slight modifications, decorations, and evolutions made by those skilled in the art within the scope of the technical solution of the present invention using the technical content disclosed above, are equivalent embodiments of the present invention; at the same time, any equivalent changes, such as modifications, decorations, and evolutions made to the above embodiments based on the substantial technology of the present invention, still fall within the protection scope of the technical solution of the present invention.
