Description

Technical Field

[0001] This utility model relates to the field of composite film production technology, and in particular to a device for preparing high-barrier aluminum-plastic easy-tear composite film. Background Technology

[0002] Aluminum-plastic easy-tear composite film is a multi-layer functional packaging material, typically made of aluminum foil, plastic film (such as PET, PE, CPP), and an easy-tear layer through dry lamination or extrusion lamination processes. Its core characteristics are high barrier properties (moisture-proof, oxygen-proof, and light-proof) and easy-tear performance, making it widely used in high-end packaging fields such as food, pharmaceuticals, and electronic components.

[0003] In the existing technology, during the preparation of aluminum-plastic easy-tear composite film, the substrate needs to be unwound. Since there is a certain amount of grease on the surface of the substrate, it needs to be ultrasonically cleaned with acetone or isopropanol. However, after the substrate is cleaned with chemical reagents, the surface of the substrate has a certain degree of humidity. It needs to be dried before the substrate can be melted using an extruder and then the subsequent pressing and lamination operation can be carried out. However, after the chemical reagents on the surface of the substrate are dried, chemical reagents still remain. During the melting process of the substrate, the chemical reagent residues will vaporize and evaporate, causing bubbles to be generated in the melt, thus affecting the quality of the aluminum-plastic easy-tear composite film. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that during the preparation of aluminum-plastic easy-tear composite film, the substrate needs to be unwound. Due to the presence of grease on the substrate surface, ultrasonic cleaning with acetone or isopropanol is required. However, after cleaning with chemical reagents, the substrate surface still has a certain degree of moisture and needs to be dried before the substrate can be melted using an extruder and then subjected to subsequent lamination operations. However, even after the chemical reagents on the substrate surface are dried, chemical reagents still remain. During the melting process, the chemical reagent residues will vaporize and evaporate, causing bubbles to form in the melt, thus affecting the quality of the aluminum-plastic easy-tear composite film.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a preparation device for a high-barrier aluminum-plastic easy-tear composite film, comprising: a base plate, and further comprising:

[0006] An ultrasonic cleaner is fixedly connected to the top of the base plate. A lower pressure roller is rotatably connected to the opposite side of the inner wall of the ultrasonic cleaner. Two support plates are symmetrically fixedly connected to the top of the base plate. An auxiliary roller is rotatably connected to the opposite side of the two support plates. An L-shaped plate is fixedly connected to one side of the support plate. A U-shaped tube is fixedly connected to the inner wall of the two L-shaped plates. Multiple nozzles are fixedly connected to both branches of the U-shaped tube at equal intervals. A water pump is fixedly connected to the other side of one of the support plates. A water outlet pipe is fixedly connected to the water outlet end of the water pump. The water outlet pipe is fixedly connected to the U-shaped tube. A water pump suction pipe is fixedly connected to the water suction end of the water pump.

[0007] A drying mechanism, located above the base plate, is used to dry the aluminum-plastic easy-tear composite film.

[0008] Preferably, the L-shaped plate is inclined, and the water outlet pipe, U-shaped pipe and multiple nozzles are connected.

[0009] Preferably, the drying mechanism includes multiple support bars, each of which is fixedly connected to a base plate. A drying box is fixedly connected to the top of each of the multiple support bars, and an opening slot is provided on each opposite side of the drying box.

[0010] Preferably, a plurality of heating wires are fixedly connected at equal intervals on opposite sides of the inner wall of the support strip, a temperature sensor is fixedly connected to one side of the inner wall of the support strip, a fan is fixedly connected to one side of the support strip, and the air outlet of the fan extends into the interior of the support strip.

[0011] Preferably, a water tank is fixedly connected to the top of the base plate near the support plate three, and a lower pressure roller two is rotatably connected to the opposite side of the inner wall of the water tank.

[0012] Preferably, two support plates are symmetrically fixedly connected to the top of the base plate near the center, and auxiliary rollers are rotatably connected to the opposite sides of the two support plates.

[0013] Preferably, the bottom plate is symmetrically fixedly connected to two support plates at the top away from the drying box, and an auxiliary roller is rotatably connected to the opposite side of the two support plates.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model connects a water pipe to a water source and controls a water pump to start, causing the water pipe to draw water from the water source. The water then passes through an outlet pipe, a U-shaped pipe, and a nozzle. With the nozzles arranged on both sides of the substrate, both sides of the substrate can be rinsed to remove residual chemical reagents from the substrate surface. The water then flows down the slope of the substrate and into the interior of the water tank. This prevents residual chemical reagents from remaining after the substrate dries, and ensures that no residual chemical reagents vaporize and evaporate during the melting process, thus preventing the formation of bubbles in the melt and improving the quality of the aluminum-plastic easy-tear composite film.

[0016] 2. This utility model uses a controller to control the heating wire to raise the temperature inside the support strip. A temperature sensor monitors the temperature inside the support strip. When the temperature is too high or too low, the temperature sensor transmits a signal to the controller, which then controls the heating wire to lower or raise the temperature. Simultaneously, the controller starts the fan to blow air into the drying chamber. With the help of the opening slot, the gas inside the support strip flows, thus air-drying the substrate. This improves the drying efficiency of the substrate and saves drying time. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figure 1-4 As shown, this utility model provides a device for preparing a high-barrier aluminum-plastic easy-tear composite film, including: a base plate 1, and an ultrasonic cleaner 103 fixedly connected to the top of the base plate 1. A lower pressure roller 104 is rotatably connected to opposite sides of the inner wall of the ultrasonic cleaner 103. Two support plates 109 are symmetrically fixedly connected to the top of the base plate 1. An auxiliary roller 110 is rotatably connected to opposite sides of the two support plates 109. An L-shaped plate 203 is fixedly connected to one side of each support plate 109. Two L-shaped plates 203 are fixedly connected to the inner walls of U-shaped pipes 204. Each of the two branches of the U-shaped pipes 204 is fixedly connected to multiple nozzles 205 at equal intervals. A water pump 2 is fixedly connected to the other side of one of the support plates 109. A water outlet pipe 201 is fixedly connected to the water outlet end of the water pump 2. The water outlet pipe 201 is fixedly connected to the U-shaped pipe 204. A water pumping end is fixedly connected to a water pumping pipe 202. A drying mechanism is set above the base plate 1 and is used to dry the aluminum-plastic easy-tear composite film.

[0026] Furthermore, such as Figure 1-4 As shown, the L-shaped plate 203 is set in an inclined shape, and the water outlet pipe 201, U-shaped pipe 204 and multiple nozzles 205 are connected. With the above configuration, when the water pump 2 is started by the controller, the water pumping pipe 202 draws water from the water source, and then the water passes through the water outlet pipe 201, U-shaped pipe 204 and nozzles 205 in sequence. With the nozzles 205 arranged on both sides of the substrate, both sides of the substrate can be rinsed.

[0027] Furthermore, such as Figure 1-4 As shown, the drying mechanism includes multiple support bars 3, all of which are fixedly connected to the base plate 1. A drying box 301 is fixedly connected to the top of the multiple support bars 3. An opening groove 305 is provided on the opposite side of the drying box 301. The substrate can pass through the drying box 301 through the opening groove 305.

[0028] Furthermore, such as Figure 1-4As shown, multiple heating wires 303 are fixedly connected at equal intervals on opposite sides of the inner wall of the support bar 3. A temperature sensor 304 is fixedly connected to one side of the inner wall of the support bar 3. A fan 302 is fixedly connected to one side of the support bar 3. The air outlet of the fan 302 extends into the interior of the support bar 3. The heating wires 303 are heated by the controller, which can raise the temperature inside the support bar 3. The fan 302 is then started by the controller, which blows air into the interior of the drying oven 301. With the cooperation of the opening slot 305, the gas inside the support bar 3 flows.

[0029] Furthermore, such as Figure 1-4 As shown, a water tank 107 is fixedly connected to the top of the base plate 1 near the support plate 3 109. A lower pressure roller 2 108 is rotatably connected to the opposite side of the inner wall of the water tank 107. The water tank 107 facilitates the collection of water for rinsing the substrate, and the lower pressure roller 2 108 facilitates the lifting of the substrate.

[0030] Furthermore, such as Figure 1-4 As shown, two support plates 105 are symmetrically fixedly connected to the top of the base plate 1 near the center. An auxiliary roller 106 is rotatably connected to the opposite side of the two support plates 105. The auxiliary roller 106 facilitates the lifting of the substrate, allowing the chemical reagents on the surface of the substrate to flow downwards.

[0031] Furthermore, such as Figure 1-4 As shown, two support plates 101 are symmetrically fixedly connected to the top of the base plate 1 away from the drying box 301. An auxiliary roller 102 is rotatably connected to the opposite side of the two support plates 101. The auxiliary roller 102 is set to assist the substrate and facilitate the unwinding of the substrate.

[0032] Working Principle: During use, when the substrate is unwound, the auxiliary roller 102, lower pressure roller 104, auxiliary roller 2 106, lower pressure roller 2 108, and auxiliary roller 3 110 work together to arrange the substrate in a V-shaped undulating pattern. With the assistance of lower pressure roller 104, the substrate is immersed in the chemical reagent in the ultrasonic cleaner 103. The controller starts the ultrasonic cleaner 103, and the chemical reagent cleans the grease on the substrate surface. Then, with the assistance of lower pressure roller 2 108, the substrate is lowered, causing it to be arranged at an angle between lower pressure roller 2 108 and auxiliary roller 3 110. The water pump 202 is connected to a water source, and the controller starts the water pump 2, drawing water from the source. The water then passes through the outlet pipe 201, U-shaped pipe 204, and nozzle 205. With the nozzles 205 positioned on both sides of the substrate, both sides of the substrate are rinsed. The washing process removes residual chemical reagents from the substrate surface and allows the water to flow downwards along the substrate's slope into the water tank 107. This prevents residual chemical reagents from remaining after the substrate is dried, ensuring that no residual chemical reagents vaporize and evaporate during the melting process, thus preventing the formation of bubbles in the melt and improving the quality of the aluminum-plastic easy-tear composite film. Simultaneously, the controller controls the heating wire 303 to heat the support strip 3, raising its internal temperature. The temperature sensor 304 monitors the internal temperature of the support strip 3, transmitting a signal to the controller when the temperature is too high or too low. The controller then controls the heating wire 303 to lower or raise its temperature accordingly. Simultaneously, the controller activates the fan 302, blowing air into the drying chamber 301. With the cooperation of the opening slot 305, the air flows inside the support strip 3, drying the substrate. This improves the drying efficiency of the substrate, saving drying time.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
