Description
Technical Field
[0001] This application relates to the technical field of anti-counterfeiting label production and manufacturing, and particularly relates to a film laminating device for anti-counterfeiting label production. Background Art
[0002] With the rapid development of the commodity economy, people's living standards have been continuously improved, their consumption concepts for commodities have gradually matured, and they have paid more and more attention to the safety and anti-counterfeiting technologies of commodities. Currently, the popular form of product anti-counterfeiting in the market is to use anti-counterfeiting labels on product packaging. There are many types of anti-counterfeiting labels. In addition to ordinary printed anti-counterfeiting labels, the more popular ones are optical anti-counterfeiting labels. As the name implies, optical anti-counterfeiting labels achieve the anti-counterfeiting effect by generating precise micro-nano structures through the principle of light.
[0003] Optical anti-counterfeiting labels are also called laser anti-counterfeiting labels and holographic anti-counterfeiting labels in the industry. Optical anti-counterfeiting labels are more complex anti-counterfeiting technologies established on the basis of laser anti-counterfeiting labels, and are anti-counterfeiting labels completed by using laser color hologram plate-making technology and die stamping replication technology. Currently, in the production process of optical anti-counterfeiting labels, a film laminating device is needed to cover a transparent protective film on the label surface, so as to effectively protect the micro-nano structures on the label from being contaminated and worn, and at the same time have a certain waterproof effect.
[0004] Existing film laminating devices usually consist of a winding module, a pressing module, and a plastic sealing module. The winding module is used to wind the label and the protective film. The pressing module is used to press the label and the protective film during the winding process, so that the protective film fits on the label surface. The plastic sealing module is used to heat and plastic-seal the label and the protective film that are attached together through a hot pressing roller. However, the position of the hot pressing roller in the existing plastic sealing module is usually not adjustable. When the label paper is thin, the downward pressure of the hot pressing roller on the protective film is small, which is likely to affect the plastic-sealing effect of the label and the protective film. When the label paper is thick, the downward pressure of the hot pressing roller on the protective film is large, which is likely to cause deformation and damage of the protective film, and also affects the plastic-sealing effect of the label and the protective film.

Detailed implementation manners
[0029] The present application will be further described in detail below with reference to the accompanying drawings.
[0030] An embodiment of the present application discloses a film laminating device for anti-counterfeiting label production. Referring to Figure 1 and Figure 2 , it includes a frame 1. A mounting plate 2 is vertically and fixedly installed on the top surface of the frame 1.

A first mounting bracket 6 and a second mounting bracket 7 are fixedly installed on the top surface of the frame 1, and the first mounting bracket 6 and the second mounting bracket 7 are arranged in sequence along the direction from the first unwinding roller 3 to the winding roller 5. A pressing mechanism is arranged on the first mounting bracket 6, and a plastic sealing assembly 8 is arranged on the second mounting bracket 7.
[0031] Referring to Figure 1 and Figure 2 , when laminating the label, the operator places the roll of protective film on the first unwinding roller 3, places the roll of label on the second unwinding roller 4, so that the protective film and the label pass through the first mounting bracket 6 and the second mounting bracket 7 in sequence, uses the pressing mechanism to bond the label and the protective film together, uses the plastic sealing assembly 8 to heat-seal the bonded label and protective film, and at the same time uses the winding roller 5 to wind the heat-sealed label and protective film.
[0032] Referring to Figure 2, the lamination mechanism includes a fixed bracket 18, which is fixedly installed on the inner bottom wall of the first mounting bracket 6. A lower pressing roller 19 is rotatably installed on the fixed bracket 18. The lamination mechanism further includes a connection assembly 22, which includes a connecting rod 221, a top plate 222 and a telescopic spring 223. The connecting rod 221 is vertically arranged and slidably penetrates through the top wall of the first mounting bracket 6. The top plate 222 is fixedly installed at the top end of the connecting rod 221. The telescopic spring 223 is fixedly sleeved on a section of the connecting rod 221 extending out of the first mounting bracket 6, and the top end of the telescopic spring 223 is fixedly connected to the top plate 222, and the bottom end of the telescopic spring 223 is fixedly connected to the first mounting bracket 6. One end of the connecting rod 221 inserted into the first mounting bracket 6 is fixedly connected with a movable bracket 20. The movable bracket 20 is located directly above the fixed bracket 18. An upper pressing roller 21 is rotatably installed on the movable bracket 20.
[0033] Referring to Figure 1 and Figure 2 , when the protective film and the label pass through the first mounting bracket 6, the protective film and the label pass through between the upper pressing roller 21 and the lower pressing roller 19. The telescopic spring 223 drives the top plate 222 and the connecting rod 221 to press downwards, thereby driving the movable bracket 20 and the upper pressing roller 21 to elastically press the protective film and the label, which helps to cooperate with the lower pressing roller 19 to laminate the label and the protective film, and thus helps to make the label and the protective film fit together.
[0034] Referring to Figure 1 and Figure 3 , the plastic sealing assembly 8 includes a placement plate 81, a placement rack 82, a hot pressing roller 83 and a top supporting spring 84. A plurality of upright columns 10 are fixed on the top surface of the second mounting bracket 7. The placement plate 81 is slidably sleeved on the plurality of upright columns 10. The top supporting spring 84 is fixedly sleeved on the outer periphery of the upright columns 10, and the top end of the top supporting spring 84 abuts against the bottom surface of the placement plate 81. The placement rack 82 is fixedly installed on the bottom surface of the placement plate 81. The hot pressing roller 83 is rotatably installed on the placement rack 82. When the protective film and the label pass through the second mounting bracket 7, the hot pressing roller 83 is used to hot-press and plastic-seal the label and the protective film, which helps to achieve the film laminating treatment of the label.
[0035] Referring to Figure 1 and Figure 3 , a first tension roller 16 and a second tension roller 17 are fixedly installed on the mounting plate 2. The first tension roller 16 and the second tension roller 17 are respectively located on both sides of the second mounting bracket 7, and the bottom surfaces of the first tension roller 16 and the second tension roller 17 are lower than the top surface of the second mounting bracket 7. When the protective film and the label pass through the second mounting bracket 7, the first tension roller 16 and the second tension roller 17 help to keep the protective film and the label that are fitted together in a tensioned state, and at the same time help to make the label and the protective film closely adhere to the top surface of the second mounting bracket 7, facilitating the hot-press plastic sealing of the label and the protective film.
[0036] Reference Figure 1 and Figure 3 Figure 3
[0037] Reference Figure 1 and Figure 3 When laminating labels of different thicknesses, the distance between the bottom surface of the hot pressing roller 83 and the protective film is measured by the laser rangefinder 94. When there is a deviation between the measured distance value and the set distance value, the electric push rod 91 drives the adjusting block 92 to move horizontally, so that the contact position between the abutting wheel 12 and the adjusting block 92 changes, which helps to use the adjusting curve surface 921 to lift and lower the abutting wheel 12 and the adjusting rod 93, thereby driving the placing plate 81 and the hot pressing roller 83 to lift synchronously, and further helping to adjust the distance between the bottom surface of the hot pressing roller 83 and the protective film, ensuring the laminating effect when the hot pressing roller 83 laminates the protective film and labels of different thicknesses, and improving the laminating effect on labels of different thicknesses.
[0038] Reference Figure 3 On the top surface of the fixing plate 11, a fixing frame 13 is fixedly installed. On the inner top wall of the fixing frame 13, a slide rail 14 is fixedly installed. A slide block 15 is slidably installed on the slide rail 14, and the slide block 15 is fixedly connected to the adjusting block 92. When the adjusting block 92 moves, the slide block 15 slides on the slide rail 14, which helps to guide the movement of the adjusting block 92, and further helps to improve the stability of the adjusting block 92 during the movement. The fixing frame 13 helps to limit the displacement of the adjusting block 92 in the vertical direction, thereby helping to ensure the adjusting effect of the adjusting block 92 on the position of the adjusting rod 93.
[0039] The implementation principle of the embodiment of the present application is as follows: When laminating labels, the operator places the rolled protective film on the first unwinding roller 3, places the rolled labels on the second unwinding roller 4, and uses the winding roller 5 to wind the labels and the protective film.
[0040] When the protective film and the label pass through the first mounting bracket 6, the protective film and the label pass between the upper pressing roller 21 and the lower pressing roller 19. The telescopic spring 223 drives the top plate 222 and the connecting rod 221 to press downward, thereby driving the movable bracket 20 and the upper pressing roller 21 to elastically press the protective film and the label, which helps to cooperate with the lower pressing roller 19 to press the label and the protective film together, thus helping to make the label and the protective film fit together. When the protective film and the label pass through the second mounting bracket 7, the hot pressing roller 83 is used to thermally press and seal the label and the protective film, which helps to achieve the film covering treatment of the label.
[0041] When performing the film covering treatment on labels of different thicknesses, the distance between the bottom surface of the hot pressing roller 83 and the protective film is measured by the laser rangefinder 94. When there is a deviation between the measured distance value and the set distance value, the electric push rod 91 drives the adjusting block 92 to move horizontally, so that the contact position between the abutting wheel 12 and the adjusting block 92 changes, which helps to use the adjusting surface 921 to lift and lower the abutting wheel 12 and the adjusting rod 93, thereby driving the placing plate 81 and the hot pressing roller 83 to lift and lower synchronously, and further helping to adjust the distance between the bottom surface of the hot pressing roller 83 and the protective film, ensuring the sealing effect when the hot pressing roller 83 seals the protective film and labels of different thicknesses, and improving the film covering effect on labels of different thicknesses.
[0042] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
