Description

Technical Field

[0001] This utility model relates to the technical field of heat sealing devices, and in particular to a heat sealing device for the production of aluminum-plastic packaging materials. Background Technology

[0002] Aluminum-plastic bags are low in cost, have exquisite printing, and are characterized by: anti-static properties, UV protection, moisture-proof, oxygen-barrier, light-blocking, cold-resistant, oil-resistant, high-temperature resistant, freshness-preserving, oxygen-barrier, and easy sealing. When producing aluminum-plastic packaging bags, they need to be sealed, which is generally done using a heat-sealing device. A vacuum heat-sealing device for aluminum bag production, with announcement number CN220595302U, belongs to the field of aluminum bag packaging technology. This device includes a processing table, a lifting support, and a pressing support shaft. It also includes a metal heating rod positioned above the processing table. A control panel is located on one side of the processing table, and a power module is installed inside the table, electrically connected to the metal heating rod. A wiring module is located on one side of the power module. The pressing support shaft is connected to the processing table via the lifting support. To address the issue of residual air in the bag opening area during heat sealing, which may prevent the bag from being sealed in one operation, a rubber wheel at the bottom of the outer support shaft slides along one end of an electrically controlled track to the other. The rubber wheel squeezes out the residual air in the bag opening area and also flattens the bag in the opening area, preventing wrinkles during heat sealing. When using the aforementioned existing technology, there is a lack of fixed restraint on the aluminum bag material during heat sealing. The aluminum bag material is prone to displacement during the heat sealing process, resulting in uneven stress on the heat-sealed area. Some areas may overheat and melt due to excessive pressure, while other areas may not be heat-sealed properly due to insufficient pressure. Overheated areas will make the packaging material thinner and more brittle, reducing the strength of the packaging. Areas that are not heat-sealed properly are prone to problems such as air leakage and damage, affecting the protective performance of the packaging. Therefore, corresponding improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a heat sealing device for the production of aluminum-plastic packaging materials, so as to solve the problem mentioned in the background art that the existing heat sealing devices for the production of aluminum-plastic packaging materials lack material positioning and are prone to material position displacement during the heat sealing process, which affects the heat sealing effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat sealing device for the production of aluminum-plastic packaging materials, comprising a heat sealing box and a cylinder, wherein the cylinder is fixed at the top of the heat sealing box; Guide columns are fixed on both sides inside the heat sealing box, and a U-shaped top frame is sleeved on the top of the outer side of the guide column. A U-shaped bottom frame is sleeved on the bottom of the outer side of the guide column. A lifting plate is sleeved between the guide columns below the U-shaped top frame. Two spring columns connect the U-shaped top frame and the lifting plate. A linkage component is provided on the outer side of the U-shaped top frame and the U-shaped bottom frame. Positioning mechanisms are provided on both sides of the bottom end of the lifting plate.

[0005] Furthermore, the linkage component includes a connecting shaft connected to the inner wall of the heat-sealing box, and a power rotating plate is movably connected to the outside of the connecting shaft. A connecting rod and the power rotating plate are movably connected to the two ends of the outside of the power rotating plate, respectively. One end of the connecting rod is movably connected to the outside of the U-shaped top frame, and the power rotating plate is movably connected to the outside of the support platform.

[0006] Furthermore, a limiting groove is provided on the inner wall of the other side of the heat sealing box, and limiting blocks are fixed on the outer sides of the U-shaped top frame and the U-shaped bottom frame. The limiting blocks slide inside the limiting groove, and the U-shaped top frame and the U-shaped bottom frame are slidably connected to the heat sealing box through the limiting blocks.

[0007] Furthermore, a heat-sealing plate is fixed to the bottom of the lifting plate, and a second heating plate is provided inside the heat-sealing plate. A support platform is fixed to the top of the U-shaped base, and a first heating plate is provided inside the support platform. Both the second heating plate and the first heating plate are connected to an external power source via wires.

[0008] Furthermore, the positioning mechanism includes a fixed sleeve block, which is fixed to the top of the lifting plate. The fixed sleeve block has a positioning block inside, and a return spring is evenly fixed at the bottom of the positioning block. The return springs are evenly distributed at the bottom of the positioning block.

[0009] Furthermore, sliders are fixed on both sides of the positioning block, and grooves are provided on both inner walls of the fixing sleeve block, with the sliders slidably connected to the grooves.

[0010] Furthermore, the height of the fixing sleeve is less than the height of the heat-sealing plate, and the height of the positioning block after extension in the stretched state of the reset spring is greater than the height of the heat-sealing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the heat sealing device for aluminum-plastic packaging material production not only has a self-positioning effect to ensure the accuracy of heat sealing, but also has high heat sealing efficiency; During the heat sealing process of the lifting plate moving down, the fixed sleeve block and the positioning block move synchronously until the positioning block contacts the aluminum-plastic packaging material. Then, the positioning block is pushed back into the fixed sleeve block, and the return spring is compressed. The two positioning blocks are used to position the aluminum-plastic packaging material, ensuring accurate heat sealing position, avoiding heat sealing deviation, ensuring uniform stress and consistent heating of the aluminum-plastic packaging material, and stabilizing the heat sealing strength, thereby improving heat sealing quality and efficiency. The cylinder is used as the driving force to push the U-shaped top frame and the lifting plate downwards, and pushes the connecting rod to move synchronously, which in turn drives the power turn plate to rotate, which in turn pulls the articulated arm upwards so that the lifting plate and the U-shaped base frame can move closer to each other and close, so as to heat seal the aluminum-plastic packaging material and ensure uniform heat sealing pressure. During this process, the limit block slides in the limit groove to limit and guide the movement of the lifting plate and the U-shaped base frame, so as to ensure the stability of the movement of the lifting plate and the U-shaped base frame. By using the second heating plate in the heat-sealing plate and the first heating plate in the support platform, the temperature of the support platform and the heat-sealing plate can be increased, so as to perform efficient and uniform heat sealing of aluminum-plastic packaging materials.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Please see Figures 1-5 The present invention provides the following technical solution: Example

[0017] To address the issue of low heat-sealing efficiency in existing heat-sealing devices used in aluminum-plastic packaging material production, the following technical solution is proposed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 3 A heat-sealing device for producing aluminum-plastic packaging materials includes a heat-sealing box 1 and a cylinder 2. The cylinder 2 is fixed to the top of the heat-sealing box 1. Guide columns 9 are fixed on both sides inside the heat-sealing box 1. A U-shaped top frame 3 is sleeved on the top of the outer side of the guide column 9, and a U-shaped bottom frame 7 is sleeved on the bottom of the outer side of the guide column 9. A lifting plate 4 is sleeved between the guide columns 9 below the U-shaped top frame 3. A limiting groove 101 is provided on the inner wall of the other side of the heat-sealing box 1. Limiting blocks 14 are fixed on the outer sides of the U-shaped top frame 3 and the U-shaped bottom frame 7. The limiting blocks 14 slide inside the limiting groove 101. The U-shaped top frame 3 and the U-shaped bottom frame 7 are slidably connected to the heat-sealing box 1 through the limiting blocks 14. A heat-sealing plate 15 is fixed to the bottom of the lifting plate 4. 5 is equipped with a second heating plate 1501 inside, and a support platform 8 is fixed at the top of the U-shaped base frame 7. The support platform 8 is equipped with a first heating plate 801 inside. Both the second heating plate 1501 and the first heating plate 801 are connected to an external power source through wires. Two spring columns 5 are connected between the U-shaped top frame 3 and the lifting plate 4. A linkage assembly is provided on the outside of the U-shaped top frame 3 and the U-shaped base frame 7. The linkage assembly includes a connecting shaft 13 connected to the inner wall of the heat sealing box 1. A power rotating plate 11 is movably connected to the outside of the connecting shaft 13. A connecting rod 10 and the power rotating plate 11 are movably connected to the two ends of the outside of the power rotating plate 11, respectively. One end of the connecting rod 10 is movably connected to the outside of the U-shaped top frame 3, and the power rotating plate 11 is movably connected to the outside of the support platform 8. In this embodiment, the aluminum-plastic heat-sealing material is placed on the support platform 8. Then, the cylinder 2 is driven to push the U-shaped top frame 3 downward, which in turn drives the connecting rod 10 downward. The end of the connecting rod 10 pushes the power rotating plate 11 to rotate, which in turn pulls the hinge arm 12 upward, which in turn drives the U-shaped base frame 7 upward. During this process, the limiting block 14 slides in the limiting groove 101, thereby limiting and guiding the movement of the lifting plate 4 and the U-shaped base frame 7 to ensure the stability of the movement of the lifting plate 4 and the U-shaped base frame 7, so that the aluminum-plastic material is heated evenly and the heat-sealing quality is improved. Then, the heat-sealing plate 15 is brought into contact with the support platform 8. The heating plate 15 and the support platform 8 are heated by the cooperation of the heating plate 11 and the heating plate 21501 to heat the aluminum-plastic material. Example

[0018] This embodiment differs from Embodiment 1 in that it utilizes the positioning mechanism 6 to position and clamp the aluminum-plastic packaging material to be heat-sealed, thereby improving the uniformity of heating and enhancing the heat-sealing quality. Therefore, the following technical solution is disclosed; please refer to the following for details. Figure 1 , Figure 4 , Figure 5 Positioning mechanisms 6 are provided on both sides of the bottom end of the lifting plate 4. The positioning mechanism 6 includes a fixed sleeve block 601, which is fixed to the top of the lifting plate 4. A positioning block 602 is provided inside the fixed sleeve block 601, and a return spring 603 is evenly fixed at the bottom end of the positioning block 602. The return springs 603 are evenly distributed at the bottom end of the positioning block 602. A slider 604 is fixed on both sides of the positioning block 602. A sliding groove 605 is provided on both inner walls of the fixed sleeve block 601. The slider 604 is slidably connected to the sliding groove 605. The height of the fixed sleeve block 601 is less than the height of the heat sealing plate 15. When the return spring 603 is stretched, the height of the positioning block 602 after extension is greater than the height of the heat sealing plate 15. In this embodiment, during the heat sealing process of the lifting plate 4 and the U-shaped base frame 7, the lifting plate 4 moves downward, driving the heat sealing plate 15, the fixing sleeve 601, and the positioning block 602 to move downward synchronously. The height of the fixing sleeve 601 is less than that of the heat sealing plate 15, so the heat sealing plate 15 contacts the aluminum-plastic packaging material first. The height of the positioning block 602, in conjunction with the return spring 603, is greater than that of the heat sealing plate 15. Therefore, during the descent of the lifting plate 4, the positioning block 602 contacts the aluminum-plastic packaging material first, thus fixing and limiting it. During this process, the return spring 603 is compressed until the heat sealing plate 15 contacts the aluminum-plastic packaging material for heat sealing, ensuring accurate heat sealing position, uniform heating of the material, and improved heat sealing quality.
