Description

Technical Field

[0001] This utility model relates to the field of bag making machine technology, and in particular to a packaging bag research and development workbench. Background Technology

[0002] Aluminum-plastic composite heavy-duty bags are packaging bags made of multiple layers of materials, typically PET or PE plastics and aluminum foil or aluminum plates bonded together by hot pressing or adhesives. These bags offer excellent moisture resistance, corrosion resistance, and UV protection, while also possessing high strength, impact resistance, and wear resistance, making them widely used in packaging food, pharmaceuticals, and chemical products. The production process of aluminum-plastic composite heavy-duty bags usually involves hot pressing or adhesive bonding to combine the plastic and metal materials. During production, careful control of parameters such as temperature, pressure, and time is crucial to ensure the produced bags have excellent performance and quality. With increasing demands for packaging quality and safety, continuous technological advancements, and the emergence of new materials, aluminum-plastic composite heavy-duty bags will continue to be innovated and improved. The most important aspect of aluminum-plastic packaging bag research and development is heat sealing. Existing bag-making machines are generally large, with simple worktable structures, which are not conducive to the research and development of aluminum-plastic packaging bags.

[0003] The prior art, such as the Chinese utility model patent with announcement number CN216610274U and announcement date of 2022-05-27, discloses an auxiliary workbench for a fully automatic bag making machine, including a fixed rod, a workbench body, a connecting plate, a connecting pipe, a fixed plate, a base plate, and a bag making machine. The lower surface of the workbench body is welded with a base plate, and the inside of the base plate has a limit groove, with a locking screw threaded into the limit groove. The upper surface of the workbench body is welded with a fixed rod, and a connecting rod is movably inserted into the upper surface of the fixed rod. A feeding table is welded to the upper surface of the connecting rod. The upper surface of the workbench body is welded with a fixed plate, and a fixed pipe is embedded and fixed inside the fixed plate. The lower surface of the fixed pipe is connected to a feeding pipe that penetrates the workbench body. The front surface of the fixed plate is threaded with a fixing bolt, and a connecting plate is movably inserted into the upper surface of the fixed plate. The bag making machine is placed on the upper surface of the workbench body. Although the patented device can feed materials and facilitate the collection of processed packaging bags, it still has certain limitations as it cannot perform heat sealing and cutting. Utility Model Content

[0004] To address the shortcomings in the aforementioned background technology, this utility model proposes a research and development workbench for aluminum-plastic packaging bags, which solves the problem that existing bag-making machines are large and the workbench structure is simple, making them unsuitable for the research and development of aluminum-plastic packaging bags.

[0005] The technical solution of this utility model is implemented as follows: an aluminum-plastic packaging bag R&D workbench includes a work platform, a lifting frame is installed at the bottom of the work platform, and a raw material rack, a cold pressing mechanism and a cutting mechanism are installed in sequence on the work platform. A hot composite roller and a power roller group are also installed between the raw material rack and the cold pressing mechanism.

[0006] More preferably, the raw material rack includes two symmetrically arranged rectangular frames, with at least two connecting rods connecting the two rectangular frames, and support components connected to the connecting rods.

[0007] More preferably, the support assembly includes a rotating shaft, with mounting plates connected to both ends of the shaft, and the mounting plates are connected to a connecting rod. A pin connects the rotating shaft and the mounting plates. A guide roller is rotatably connected to the rectangular frame.

[0008] More preferably, the power roller includes two relatively rotating roller shafts, each end of which is connected to a support frame, and one end of the roller shaft extends out of the support frame and is connected to a drive motor mounted on the work platform.

[0009] More preferably, the cold pressing mechanism includes a lower plate and an upper plate corresponding to the lower plate. The lower plate is fixedly connected to the working platform, and a lifting cylinder is connected to the upper part of the upper plate. The lifting cylinder is connected to the mounting frame set on the working platform, and a cooling component is also connected to the upper plate.

[0010] More preferably, the cooling component includes a twisted tube and a cooling water tank. The twisted tube is fixedly installed on the upper plate and connected to the cooling water tank via a flexible hose. The cooling water tank is installed on a mounting bracket and contains a water pump that works with the twisted tube.

[0011] More preferably, the cutting mechanism includes a cutter and a limiting plate. At least two lifting cylinders are connected to the cutter. The lifting cylinders are connected to the limiting plate. The limiting plate is provided with a blade groove corresponding to the cutter. The limiting plate is connected to the working platform.

[0012] More preferably, the lifting frame includes a cabinet, the lower part of which is equipped with self-locking casters, and the upper part of the cabinet is connected to the work platform by at least four hydraulic lifting cylinders.

[0013] The beneficial effects of this utility model are as follows: The aluminum film material is installed on the raw material rack and, under the action of the power roller, is thermally bonded into a whole around the thermal composite roller. Then, the power roller sends the thermally bonded aluminum film into the cold pressing mechanism for cold pressing and flattening. After cold pressing and flattening, it is then cut. This process is highly efficient and facilitates the development of new aluminum films, thus improving R&D efficiency. At the same time, the integration of thermal bonding, cold pressing, and preliminary cutting on the work platform can improve the efficiency of packaging bag R&D. Attached Figure Description

[0018] 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.

[0019] like Figure 1 As shown in Embodiment 1, an aluminum-plastic packaging bag R&D workbench includes a work platform 1. A lifting frame is installed at the lower part of the work platform 1. A raw material rack, a cold pressing mechanism, and a cutting mechanism are sequentially installed on the work platform 1. A thermal bonding roller 2 and a power roller group are also installed between the raw material rack and the cold pressing mechanism. Aluminum film material is installed on the raw material rack and thermally bonded into a whole around the thermal bonding roller 2 under the action of the power roller. Then, the power roller sends the thermally bonded aluminum film into the cold pressing mechanism for cold pressing and flattening. After cold pressing and flattening, it is cut. This method has high production efficiency, facilitates material R&D, improves R&D efficiency, enhances the performance and safety of packaging bags, and reduces production costs.

[0020] In this embodiment, the raw material rack includes two symmetrically arranged rectangular frames 3, with at least two connecting rods 4 connecting the two rectangular frames 3, and support components connected to the connecting rods 4. Specifically, the raw material rack contains aluminum foil and plastic film. Aluminum foil, as a major component of the aluminum-plastic composite bag, directly affects product quality. Typically, aluminum foil with a thickness of 0.01-0.03 mm is selected, and different aluminizing methods and ester paint coatings are chosen according to product requirements. Plastic film is another important material for aluminum-plastic composite bags, and it is generally made of materials such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). Different plastic films are selected according to product requirements.

[0021] In this embodiment, the support assembly includes a rotating shaft 6, with mounting plates 5 connected to both ends of the rotating shaft 6. The mounting plates 5 are connected to the connecting rod 4. A pin 7 connects the rotating shaft 6 and the mounting plates 5. A guide roller 8 is rotatably connected to the rectangular frame 3. Aluminum foil and plastic film are placed on the corresponding rotating shafts 6 according to a certain ratio. The guide roller 8 ensures accurate heat sealing of the material's usage area and position. The output end of the guide roller is on the same plane as the input end of the heat-sealing roller 2. The power roller includes two relatively rotating roller shafts 9, with support frames 10 connected to both ends of the roller shafts 9. One end of the roller shaft 9 extends out of the support frame 10 and is connected to a drive motor 11 mounted on the work platform 1. The drive motor 11 drives the roller shafts to rotate as a conventional method for power rollers, which will not be described in detail here. The aluminum foil and plastic film are fed into the heat-sealing roller 2, and are laminated by high temperature and pressure, thus tightly bonding the aluminum foil and plastic film together to form an aluminum-plastic composite film. The heat-sealing roller 2 is a commonly used heat-sealing structure, which will not be described in detail here.

[0022] like Figure 1 As shown in Embodiment 2, an aluminum-plastic packaging bag R&D workbench differs from Embodiment 1 in that the cold pressing mechanism includes a lower plate 12 and an upper plate 13 corresponding to the lower plate 12. The upper surface of the lower plate 12 is on the same plane as the output end of the power roller. The lower plate 12 is fixedly connected to the work platform 1. A lifting cylinder 17 is connected to the upper part of the upper plate 13. The lifting cylinder 17 is connected to a mounting frame 18 set on the work platform 1. A cooling component is also connected to the upper plate 13. The cooling component includes a twisted tube 14 and a cooling water tank 16. The twisted tube 14 is fixedly installed on the upper plate 13 and is connected to the cooling water tank 16 through a hose 15. The cooling water tank 16 is installed on the mounting frame 18 and contains a water pump that cooperates with the twisted tube 14. The twisted tube 14 is an S-shaped tube. A water pump and a twisted tube 14 are used to form a water-cooled system to cool the upper plate 13, which can cool and shape the aluminum-plastic composite film after the composite is completed, so as to ensure its physical properties and appearance quality.

[0023] In this embodiment, the cutting mechanism includes a cutter 20 and a limiting plate 21. At least two lifting cylinders 19 are connected to the cutter 20, and these cylinders are connected to the limiting plate 21. The limiting plate 21 has a groove corresponding to the cutter 20 and is connected to the work platform 1. The aluminum-plastic composite film is cut according to size requirements to obtain the initial shape of the aluminum-plastic composite bag. The lifting frame includes a cabinet 22, with self-locking casters 24 installed at the bottom. At least four hydraulic lifting cylinders 23 are connected between the upper part of the cabinet 22 and the work platform 1. Although the aluminum-plastic composite bag production process is complex, through scientific and reasonable management and technological innovation, efficient and high-quality production can be achieved to meet market demands.

[0024] All other structures are the same as in Example 1.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
