Description

Technical Field

[0001] This utility model specifically relates to a PS foamed aluminum foil insulation paperboard production line, belonging to the technical field of insulation paperboard production lines. Background Technology

[0002] PS foamed aluminum foil insulation paperboard is a high-performance composite insulation material composed of a polystyrene (PS) foam layer, an aluminum foil layer, and a kraft paper layer. This structure gives the material excellent thermal insulation, moisture resistance, and strength properties, making it widely used in cold chain logistics, biomedicine, and high-end food packaging.

[0003] In existing technologies, the production of PS foamed aluminum foil insulation paperboard typically employs either a step-by-step lamination method or a single-sided lamination method. However, both methods have certain drawbacks: the step-by-step lamination method has a long production process, low efficiency, and large footprint; repeated baking can easily lead to substrate aging; uneven stress between layers can easily cause delamination and curling, resulting in a high scrap rate; the single-sided lamination method can only perform single-sided lamination, requiring the purchase of two production lines or repeated production twice to obtain a double-sided heterogeneous structure, resulting in large equipment investment, high energy consumption, and inconsistent performance on both sides of the product. Neither of these common production methods can achieve a one-time synchronous lamination molding of a high-performance structure of "kraft paper-PS foamed sheet-aluminum foil," thereby reducing production efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a PS foamed aluminum foil insulation paperboard production line. It includes two sets of sheet feeding racks, symmetrically arranged at the beginning of the production line. Each sheet feeding rack is used to feed PS foamed sheets. A composite assembly is connected to the rear end of each sheet feeding rack. The composite assembly includes at least an oil-foaming zone, a guide roller group, and a water-cooling zone. An adhesive applicator and a film feeding rack are sequentially placed at the rear end of the composite assembly. An aluminum film unwinding shaft and a kraft paper unwinding shaft are driven on the film feeding rack. A laminating assembly is located at the rear end of the film feeding rack. The laminating assembly consists of a temperature controller and multiple sets of pressure rollers. The aluminum film, kraft paper, and PS foamed sheets pass through synchronously under the action of the pressure roller group, forming a three-layer composite structure. A cross-cutting section and a sheet receiving platform are sequentially provided at the rear end of the laminating assembly. The sheet receiving platform is located at the end of the production line.

[0005] The film loading rack includes two workstations arranged horizontally side by side, and each workstation is equipped with an independent drive source.

[0006] The composite component has a temperature sensor and an automatic temperature control device in the oil foaming zone to control the foaming temperature.

[0007] The gluing equipment adopts precision coating technology and is equipped with a glue quantity control system.

[0008] The aluminum film unwinding shaft of the film unwinding frame is arranged perpendicularly to the kraft paper unwinding shaft.

[0009] A temperature sensor is embedded inside the pressure roller.

[0010] Beneficial effects:

[0011] The film feeding rack enables roll changing without stopping the machine, and the composite components are used for precise foaming and shaping. The gluing equipment ensures uniform distribution of the adhesive, and the film feeding rack simultaneously feeds aluminum film and kraft paper materials, so that the glued sheet, aluminum film and kraft paper meet at the laminating component. Under the temperature and pressure of the temperature controller and pressure roller group, the three-layer composite structure is completed simultaneously in one go, which improves production efficiency compared with the traditional step-by-step lamination process.

Detailed Implementation

[0017] 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.

[0018] Please see Figures 1-4As shown, the PS foamed aluminum foil insulation paperboard production line includes two sets of sheet feeding racks 1, which are symmetrically arranged at the beginning of the production line. The sheet feeding racks 1 are used to feed PS foamed sheets. The rear end of the sheet feeding racks 1 is connected to a composite component 2. The composite component 2 includes at least an oil foaming zone 201, a guide roller group 202, and a water cooling zone 203. The rear end of the composite component 2 is sequentially equipped with an adhesive applicator 3 and a film feeding rack 4. The film feeding rack 4 is driven by an aluminum film unwinding shaft 401 and a kraft paper unwinding shaft 402. The rear end of the film feeding rack 4 is equipped with a laminating component 5, which consists of a temperature controller 501 and multiple sets of pressure rollers 502. The aluminum film, kraft paper, and PS foamed sheets pass through synchronously under the action of the pressure roller group 502 and form a three-layer composite structure. The rear end of the laminating component 5 is sequentially equipped with a cross-cutting section 6 and a receiving platform 7, which is located at the end of the production line.

[0019] The sheet-laying rack 1 is used to place the intermediate substrate PS foamed sheet. The arrangement of two sets of sheet-laying racks 1 allows for flexible selection of single or double substrate sheets according to product thickness requirements, adapting to the production needs of different products. The oil foaming zone 201 uses an oil foaming process to expand the sheet into a porous structure, reducing thermal conductivity and improving insulation performance. The guide roller group 202 guides and transports the foamed sheet to the water-cooling zone 203, ensuring the flatness and stability of the sheet during transport. The water-cooling zone 203 cools and shapes the foamed sheet, preventing deformation and ensuring the structural stability and consistency of the final product. Simultaneously, the composite component 2, through the cooperation of the oil foaming zone 201, guide roller group 202, and water-cooling zone 203, allows single or double core materials to be foamed and laminated into a thicker material before entering subsequent processes. Double sheets, due to appropriate processing... The heat temperature allows for good bonding, so no adhesive is needed in this process. The gluing equipment 3 evenly coats the surface of the PS foam sheet after it has been treated by the composite component 2 with adhesive. The film feeding rack 4 is used to simultaneously feed two different surface materials, aluminum film and kraft paper. The aluminum film unwinding roller 401 and the kraft paper unwinding roller 402 are used to feed the aluminum film and kraft paper respectively. The aluminum film serves as a barrier layer, and the kraft paper serves as a printing decoration and reinforcement layer. The laminating component 5 is used to simultaneously laminate the aluminum film and kraft paper fed by the film feeding rack 4 with the glued intermediate substrate at this station. The temperature is controlled by the temperature controller 501 and the pressure is applied by the pressure roller group 502 to complete the three-layer composite structure of "kraft paper-PS foam layer-aluminum foil" in one go. The cross-cutting part 6 is used to cut the continuously formed composite board to a fixed length. The receiving table 7 is used to collect the cut composite board for subsequent processing and packaging.

[0020] Furthermore, the film loading rack 1 includes two workstations arranged horizontally side by side, each with an independent drive source; the arrangement of the two workstations allows one workstation to load another roll of material as a backup while it is in operation, realizing roll changing without stopping the machine and improving production efficiency and continuity.

[0021] Furthermore, the oil foaming zone 201 of the composite component 2 is equipped with a temperature sensor and an automatic temperature control device to control the foaming temperature; wherein the temperature sensor is used to monitor the foaming temperature in real time, and the automatic temperature control device automatically adjusts the foaming temperature according to the feedback of the temperature sensor to accurately control the temperature.

[0022] Furthermore, the gluing equipment 3 adopts precision coating technology and is equipped with a glue quantity control system. The precision coating technology ensures that the adhesive is evenly distributed on the surface of the PS foam sheet, avoiding poor interlayer bonding caused by uneven glue quantity. The glue quantity control system is used to control the amount of adhesive applied to prevent too much or too little glue.

[0023] Furthermore, the aluminum film unwinding shaft 401 and the kraft paper unwinding shaft 402 of the film unwinding frame 4 are arranged perpendicularly; the arrangement facilitates the feeding and alignment of the aluminum film and kraft paper, reduces mutual interference between the two materials during the feeding process, and the vertical arrangement also saves space, making the production line layout more compact.

[0024] Furthermore, a temperature sensor is embedded inside the pressure roller 502; the temperature sensor is used to monitor the temperature of the pressure roller 502 in real time, reducing poor interlayer bonding or material deformation caused by unsuitable temperature.

[0025] Work steps: First, based on the product thickness requirements, select to feed single or double sheets of PS foamed material. Utilizing two horizontally arranged parallel workstations, roll changing is achieved without stopping the machine, ensuring continuous production. The sheet then enters the oil foaming zone 201, where it expands through the oil foaming process to form a porous structure, reducing thermal conductivity and improving insulation performance. An internal temperature sensor monitors the foaming temperature in real time, and an automatic temperature control device automatically adjusts the temperature based on feedback, ensuring precise control of the foaming process, guaranteeing foaming uniformity and product quality. After foaming, the sheet is smoothly guided to the water cooling zone 203 via guide rollers 202. Here, the sheet is cooled and shaped in the water cooling zone 203 to prevent deformation. During this process, for double-sheet operation, [further details are needed]. At a suitable heating temperature, the two sheets can be well bonded together to form a thicker porous structure without the need for additional adhesive. After being processed by the composite component 2, the sheet enters the gluing equipment 3. The glued sheet moves to the film unwinding rack 4. The aluminum film unwinding shaft 401 and the kraft paper unwinding shaft 402 simultaneously unwind the aluminum film and kraft paper. The glued sheet, aluminum film, and kraft paper meet at the laminating component 5. At the same time, the temperature controller 501 controls the lamination temperature. Under precise temperature and pressure control, the pressure roller group 502 allows the aluminum film, kraft paper, and PS foam sheet to pass through synchronously and form a strong three-layer composite structure. Finally, the continuously formed composite board enters the cross-cutting section 6 for cutting and is collected by the receiving table 7.
