DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below. Figure 1 and Figure 2 An embodiment of the present invention provides a laminating device, comprising a feeding mechanism 100, a laminating mechanism 200, and a discharge mechanism 310. The feeding mechanism 100 is used to discharge the coils of products to be laminated. The feeding mechanism 100 includes at least two groups of feeding assemblies 110, and the two groups of feeding assemblies 110 are longitudinally distributed on the frame of the feeding mechanism 100. Each group of feeding assemblies 110 includes at least two discharge shafts 111, and two product coils are respectively arranged on the two discharge shafts 111. The product coils on the two discharge shafts 111 are staggered a certain distance in the width direction, so that the products discharged from the two product coils enter the laminating mechanism 200 side by side. The laminating mechanism 200 is used to laminarize the products discharged from the feeding mechanism 100. The width of the laminating mechanism 200 is greater than the sum of the width and spacing of the two rolls of products discharged from the feeding assembly 110. The unloading mechanism 310 is used to roll the products pressed by the pressing mechanism 200. The unloading mechanism 310 includes multiple sets of unloading assemblies 310. The number of unloading assemblies 310 corresponds to the number of loading assemblies 110. Two or more sets of unloading assemblies 310 are longitudinally distributed on the frame of the unloading mechanism 310. Each set of unloading assemblies 310 includes at least two winding shafts 311. The two winding shafts 311 can roll two side-by-side product sheets into two rolls that are offset a certain distance in the width direction.

[0030] In this laminating device, since each set of feeding components 110 can feed at least two rolls of products side by side into the laminating mechanism 200, and the width of the laminating mechanism 200 is greater than the sum of the width of the products and the spacing between them, the laminating mechanism 200 can simultaneously laminarize multiple rolls of products placed side by side. Multiple sets of feeding components 110 are distributed longitudinally, allowing multiple groups of products to be stacked together and then fed into the laminating mechanism 200, allowing the laminating device to laminarize at least four groups of products simultaneously, thereby improving production efficiency. Furthermore, in this laminating device, multiple rolls of products can share the laminating mechanism 200 and other mechanisms, thereby occupying less space than when multiple laminating devices are arranged side by side, thereby improving the utilization rate of workshop space and increasing workshop efficiency.

[0031] It is understood that in some embodiments, the products discharged by the two sets of discharge components can enter the pressing mechanism 200 in a back-to-back manner. In some embodiments, in order to improve the pressing effect, refer to Figure 5The pressing mechanism 200 includes a pressing bracket 210, an upper pressing die group 220, a lower pressing die group 240, a medium pressure die group 230 and a pressing drive mechanism 250. The medium pressure die group 230 is arranged between the upper pressing die group 220 and the lower pressing die group 240. The pressing drive mechanism 250 can drive the lower pressing die group 240 to lift, so that the lower pressing die group 240, the medium pressure die group 230 and the upper pressing die group 220 are pressed together. The products discharged from the upper loading assembly 110 and the lower unloading assembly 310 pass through between the upper pressing die set 220 and the intermediate pressing die set 230, and between the intermediate pressing die set 230 and the lower pressing die set 240, respectively, so that the upper and lower layers of products are pressed together by the upper pressing die set 220 and the intermediate pressing die set 230, and the intermediate pressing die set 230 and the lower pressing die set 240, respectively, so that both the front and back sides of the upper and lower layers of products can be pressed together well. The upper pressing die set 220 is fixedly mounted on the top of the pressing bracket 210, and the lower pressing die set 240 is located directly below the upper pressing die set 220. The lower pressing die set 240 can be raised and lowered in the vertical direction under the drive of the pressing drive mechanism 250. The pressing bracket 210 is provided with a middle die support frame 211 for supporting the middle pressure die set 230. The middle pressure die set 230 is placed on the middle die support frame 211. The middle pressure die set 230 is erected between the upper pressing die set 220 and the lower pressing die set 240 via the middle die support frame 211. When the lower pressing die set 240 is lifted by the pressing drive mechanism 250, it will first press the lower pressing surface of the middle pressure die set 230, and then lift the middle pressure die set 230 from the middle die support frame 211. The middle pressure die set 230 and the lower pressing die set 240 are lifted together until the upper pressing surface of the middle pressure die set 230 presses the lower pressing surface of the upper pressing die set 220, thereby achieving a good pressing of both sides of the upper and lower layers of the product. When the pressing mechanism 200 needs to be produced in a back-to-back manner, the medium-pressure clamping die set 230 can be removed from the pressing bracket 210; when the production needs to be carried out in a separate pressing manner, the medium-pressure clamping die set 230 is placed on the pressing bracket 210.

[0032] It is understood that the pressing drive mechanism 250 can be a hydraulic cylinder or a lifting mechanism driven by a heavy motor. Figure 5 and Figure 9In this embodiment, the pressing mechanism 200 presses the product by means of hot pressing. The upper pressing module 220 and the lower pressing module 240 both include a pressing seat 221, a heating plate 222 and a jig plate 223. The heating plate 222 is arranged between the jig plate 223 and the pressing seat 221, and the jig plate 223 is arranged on the side of the heating plate 222 facing the product. The pressing seat 221 of the upper pressing module 220 is connected to the pressing bracket 210, and the pressing seat 221 of the lower pressing module 240 is connected to the pressing drive mechanism 250. The medium pressure module 230 includes a heating plate 222 and two jig plates 223. The two jig plates 223 are respectively arranged on the upper and lower sides of the heating plate 222. A heating mechanism is provided in the heating plate 222. The heating mechanism can be an electric thermal resistor or a channel for the flow of heat transfer media such as hot oil.

[0033] Reference Figure 5 and Figure 9 In this embodiment, in order to facilitate the replacement and maintenance of the jig plate 223, the jig plate 223 is detachably arranged on the heating plate 222. Taking the medium-pressure clamping module 230 as an example, pressure blocks 2221 are provided at both ends of the upper and lower surfaces of the heating plate 222. A slot along the width direction of the product is formed between the pressure block 2221 and the surface of the heating plate 222. Insert strips 2231 that match the shape of the slot are provided at both ends of the jig plate 223, so that the jig plate 223 can be inserted into the slot, thereby realizing rapid disassembly and assembly of the jig plate 223 and the heating plate 222. A handle is provided on the side of the jig plate 223 to further facilitate the disassembly and assembly of the jig plate 223. The press-fitting bracket 210 consists of two parallel support plates mounted on the base of the press-fitting mechanism 200. The upper press-fitting module 220, the intermediate press-fitting module 230, and the lower press-fitting module 240 are positioned between the two support plates. Through holes are provided on the support plates to facilitate assembly and disassembly of the jig plate 223. The intermediate module support bracket 211 includes four support beams. Module support blocks 231 are positioned at the four corners of the heating plate 222 of the intermediate press-fitting module 230. The four support blocks of the intermediate press-fitting module 230 can be placed on the four corresponding support beams, thereby positioning the intermediate press-fitting module 230 between the upper press-fitting module 220 and the lower press-fitting module 240.

[0034] Reference Figure 6 and Figure 7In some embodiments, in order to prevent the temperature of the laminating mechanism 200 from melting the glue on the product on the front side of the laminating mechanism 200 during the hot laminating process, thereby affecting the laminating quality of the product, a cooling mechanism is provided at the entrance of the laminating mechanism 200. In this embodiment, a first cooling mechanism 260 is provided at the entrance of the lower laminating module 240, and a second cooling mechanism 270 is detachably provided on the first cooling mechanism 260. When back-to-back production is adopted, the second cooling mechanism 270 on the first cooling mechanism 260 can be removed, and the back-to-back stacked products are cooled by the first cooling mechanism 260; when the upper and lower layers of products are hot-pressed separately, the second cooling mechanism 270 is installed on the first cooling mechanism 260, and the first cooling mechanism 260 and the second cooling mechanism 270 cool the lower and upper products respectively.

[0035] Reference Figure 7In this embodiment, the first cooling mechanism 260 includes a first lower cooling plate 262, a first upper cooling plate 263 and a first cooling drive mechanism 261, and the second cooling mechanism 270 includes a second lower cooling plate 272, a second upper cooling plate 273 and a second cooling drive mechanism 271. The first lower cooling plate 262, the first upper cooling plate 263, the second lower cooling plate 272 and the second upper cooling plate 273 are all provided with a cooling mechanism, which can be a semiconductor refrigerator or a channel for a cooling medium to pass through. The first lower cooling plate 262 is fixedly provided on the front end surface of the lower pressing module 240 by the first cooling drive mechanism 261, and the first upper cooling plate 263 is fixedly provided on the pressing bracket 210. The first upper cooling plate 263 is provided directly above the first lower cooling plate 262, and the first cooling drive mechanism 261 is used to drive the first lower cooling plate 262 to press together with the first upper cooling plate 263. A first plug-in component 2631 is provided on the upper side of the first upper cooling plate 263, and a second plug-in component 2711 matching the first plug-in component 2631 is provided below the second cooling drive mechanism 271. The second cooling drive mechanism 271 can be detachably connected to the first upper cooling plate 263 by plugging the second plug-in component 2711 into the first plug-in component 2631. A plug-in bracket 212 is provided at the front end of the pressing bracket 210. The plug-in bracket 212 is provided at the front end of the pressing surface of the upper pressing module 220. A third plug-in component 2731 matching the plug-in bracket 212 is provided on both sides of the second upper cooling plate 273. The second upper cooling plate 273 can be detachably arranged above the first cooling mechanism 260 by plugging the plug-in bracket 212 through the third plug-in component 2731. The second lower cooling plate 272 is disposed on the second cooling drive mechanism 271. The second cooling mechanism 270 is used to drive the second lower cooling plate 272 to press together with the second upper cooling plate 273. In this embodiment, the first cooling drive mechanism 261 and the second cooling drive mechanism 271 are both driven by cylinders. When the pressing mechanism 200 is pressed together, the first lower cooling plate 262 and the second lower cooling plate 272 are respectively pressed together with the first upper cooling plate 263 and the second upper cooling plate 273 under the drive of the two cylinders, pressing the product in front of the pressing mechanism 200 to cool the product in front of the pressing mechanism 200 and prevent the high temperature of the pressing mechanism 200 from melting the glue on the product in front. It is understandable that the second cooling mechanism 270 can also be quickly disassembled and assembled with the first cooling mechanism 260 by clamping or magnetic attraction.

[0036] Reference Figure 5 and Figure 10In some embodiments, to prevent the product from being damaged by the laminating mechanism 200 during the laminating process, a protective film and protective auxiliary materials are placed between the product and the upper laminating die set 220, the lower laminating die set 240, and the intermediate laminating die set 230 during laminating. In this embodiment, the loading assembly 110 further includes a first protective film unloading shaft 112, a first protective auxiliary material unloading shaft 113, a second protective film unloading shaft 114, and a second protective auxiliary material unloading shaft 115. The first protective film unloading shaft 112 is used to unload a roll of protective film, and the first protective auxiliary material unloading shaft 113 is used to unload a roll of protective auxiliary material, so that the protective film unloaded from the first protective film unloading shaft 112 is located on the side of the product facing the upper laminating die set 220 or the lower laminating die set 240, and the protective auxiliary material unloaded from the first protective auxiliary material unloading shaft 113 is located on the side of the protective film facing the upper laminating die set 220 or the lower laminating die set 240. The second protective film unwinding shaft 114 is used to unwind the roll of protective film, and the second protective auxiliary material unwinding shaft 115 is used to unwind the roll of protective auxiliary material, so that the protective film unwinded from the second protective film unwinding shaft 114 is located on the side of the product facing the medium-pressure clamping assembly 230, and the protective auxiliary material unwinded from the second protective auxiliary material unwinding shaft 115 is located on the side of the protective film facing the medium-pressure clamping assembly 230. The unloading assembly 310 also includes a first protective film take-up shaft 312, a first protective auxiliary material take-up shaft 313, a second protective film take-up shaft 314, and a second protective auxiliary material take-up shaft 315. The first protective film take-up shaft 312 is used to roll the protective film unwinded from the first protective film unwinding shaft 112, and the first protective auxiliary material take-up shaft 313 is used to roll the protective auxiliary material unwinded from the first protective auxiliary material unwinding shaft 113. The second protective film unwinding shaft 114 is used to unwind the protective film roll, and the second protective auxiliary material unwinding shaft 115 is used to unwind the protective auxiliary material roll, so that the protective film unwinded from the second protective film unwinding shaft 114 is located on the side of the product facing the medium-pressure clamping assembly 230, and the protective auxiliary material unwinded from the second protective auxiliary material unwinding shaft 115 is located on the side of the protective film facing the medium-pressure clamping assembly 230. The second protective film take-up shaft 314 is used to take up the protective film unwinded from the second protective film unwinding shaft 114 into a roll, and the second protective auxiliary material take-up shaft 315 is used to take up the protective auxiliary material unwinded from the second protective auxiliary material unwinding shaft 115 into a roll. It is understood that the unwinding shaft 111, the winding shaft 311, the first protective film take-up shaft 312, the first protective auxiliary material take-up shaft 313, the second protective film take-up shaft 314, and the second protective auxiliary material take-up shaft 315 can all be driven by motors to rotate to wind the products, protective film, and protective auxiliary materials into rolls. The width of the protective film and protective auxiliary materials must also be greater than the sum of the width and spacing of the side-by-side products to fully cover the surfaces of all the side-by-side products during lamination.The unloading shaft 111 and the winding shaft 311 should preferably adopt pneumatic shafts, or a coil positioning structure, such as an adjustable baffle, should be set on the unloading shaft 111 and the winding shaft 311 to facilitate the adjustment of the position of the product coil, so as to achieve the staggered distance of the product coils on the two unloading shafts 111 in the width direction, so that the products on the two unloading shafts 111 can enter the mechanism side by side.

[0037] In some embodiments, if the products discharged by the two sets of loading assemblies 110 are placed back-to-back into the laminating mechanism 200 for production, there is no need to place a protective auxiliary material and protective film take-up shaft between the upper and lower layers of products. The loading assemblies 110 and the unloading assemblies 310 can remove the second protective film discharge shaft 114, the second protective auxiliary material discharge shaft 115, the second protective film take-up shaft 314, and the second protective auxiliary material take-up shaft 315. However, an isolation film must be placed between the two layers of products to prevent the two layers of products from sticking together after lamination. The loading mechanism 100 includes an isolation loading assembly, and the unloading mechanism 310 includes an isolation unloading assembly. The isolation loading assembly is disposed between the two sets of loading assemblies 110, and the isolation unloading assembly is disposed between the two sets of unloading assemblies 310. The isolation loading assembly is used to discharge the roll of isolation film so that the isolation film is located between the two groups of products discharged by the two sets of loading assemblies 110. The isolation unloading assembly is used to rewind the isolation film discharged by the isolation loading assemblies into a roll. The isolation feeding assembly may include an isolation film unloading shaft, and the isolation receiving assembly may include an isolation film receiving shaft that can rotate under the drive of a motor. It is understood that a plurality of transition rollers are also provided on the belt path of the product, protective film, protective auxiliary material and isolation film.

[0038] Reference Figure 8 In some embodiments, to separate the protective film from the product after lamination, a separation mechanism 280 is provided at the exit of the lamination mechanism 200. This separation mechanism 280 is used to separate the protective film and protective auxiliary materials from the product. In this embodiment, the separation mechanism 280 includes two sets of separation rods, each of which includes two separation rods 281. The two separation rods 281 are arranged along the width of the product, with a certain distance between them. The two separation rods 281 extend between the upper and lower surfaces of the corresponding product and the protective film, thereby separating the products from the protective film and protective auxiliary materials of the two sets of loading assemblies 110.

[0039] Reference Figure 3In some embodiments, in order to ensure the quality of lamination and avoid wrinkles on the product during lamination, the feeding mechanism 100 includes a pull-back mechanism 120. The pull-back mechanism 120 is arranged on the belt path of the product. The pull-back mechanism 120 is used to pull the product back so that the product in the lamination mechanism 200 can be tensioned. When back-to-back production is adopted, only one set of pull-back mechanisms 120 can be set. The products released by the two sets of feeding components 110 are first stacked back to back and then pass through the pull-back mechanism 120 and enter the lamination mechanism 200. When two layers of products are pressed separately, two sets of pull-back mechanisms 120 need to be set. The two sets of pull-back mechanisms 120 are respectively arranged on the belt paths of the products of the two sets of feeding components 110. Refer to Figure 4 The pull-back mechanism 120 includes a pull-back pressing mechanism 121, a pull-back driving mechanism 122, and a pull-back rear pressing mechanism 123. The pull-back rear pressing mechanism 123 is arranged on the side of the pull-back pressing mechanism 121 close to the pressing mechanism 200. The pull-back pressing mechanism 121 and the pull-back rear pressing mechanism 123 can clamp the product passing through. The pull-back pressing mechanism 121 can move along the belt path of the product under the drive of the pull-back driving mechanism 122. In this embodiment, the pull-back pressing mechanism 121, the pull-back driving mechanism 122, and the pull-back rear pressing mechanism 123 are all driven by cylinders. When the pull-back driving mechanism 122 drives the pull-back pressing mechanism 121 to pull back, the pull-back pressing mechanism 121 clamps the product passing through, and at the same time, the pull-back rear pressing mechanism 123 releases the product. After the pull-back is completed, the pull-back rear pressing mechanism 123 clamps the released product until the pressing mechanism 200 completes one pressing.
