Description

Technical Field

[0001] This application relates to the technical field of food packaging bag production equipment, and in particular to a composite machine for producing food packaging bags. Background Technology

[0002] A laminating machine for food packaging bags is a type of mechanical equipment specifically designed for producing food packaging bags. It plays a crucial role in the food packaging industry. Its principle is generally to first apply a layer of adhesive to a substrate, then evaporate the solvent in the adhesive through a drying channel, and then laminate it with another substrate under heating and pressure. This process enables different substrates to be firmly bonded together, and the laminated material has good barrier properties and water resistance.

[0003] A search revealed Chinese patent application CN202123057257.5, which discloses a dry laminating machine for producing plastic packaging bags. Belonging to the technical field of dry laminating machines, its key technical features include a main body with a U-shaped fixing frame mounted on its upper surface. Air chambers are fixedly connected to both the upper and lower ends of the front end face of the connecting plate. Multiple air outlet pipes are connected to opposite sides of the two air chambers. A cold water tank is mounted on the rear end face of the main body, and a fan is mounted on the upper end face of the cold water tank. A cold air duct is connected to the lower end face of the fan. The other end of the cold air duct passes through the cold water tank and extends to the outside of the tank. Two connecting pipes are connected to the front end face of the cold air duct. The front ends of both connecting pipes pass through the connecting plate and are respectively connected to the rear end faces of the two air chambers. This design facilitates the cooling and rewinding of the dried plastic packaging bags, preventing the difficulty in lowering the temperature of the rewound plastic packaging bags and thus avoiding potential issues affecting product quality.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: When laminating materials, due to excessively high adhesive viscosity and poor fluidity, it is difficult to distribute the adhesive evenly during the coating process. Uneven pressure distribution on the laminating rollers can also lead to uneven thickness, resulting in localized accumulation or uneven thickness. Furthermore, unstable adhesive content can cause inconsistent film thickness after drying, affecting the overall thickness of the laminated plastic bag, impacting its visual appeal, and reducing the product's aesthetics and grade. Additionally, many adhesives on the market contain volatile organic compounds (VOCs). During the drying process, these organic solvents evaporate into the air, producing a pungent odor and polluting the working environment. Utility Model Content

[0015] 1. This utility model incorporates components such as an electric telescopic cylinder, a combination plate, a pressure sensor, a force-generating block, a spring, a U-shaped frame, and a contact roller. The electric telescopic cylinder pushes the contact roller to contact the upper side of the composite material. When the material is stably wound by the winding component, the contact roller is in a stable state. When the composite material has protrusions, the thicker part will exert a reaction force on the contact roller. This force is applied to the force-generating block by the compression spring, and the data is then displayed from the pressure sensor. The pressure sensor can be connected to a corresponding alarm device, and an alarm can be triggered when the value changes to a certain extent. This facilitates the monitoring of the flowing composite plastic and ensures that it meets the quality requirements of the subsequent material.

[0016] 2. By incorporating a sealed door and an exhaust assembly, this invention enables the heating of flowing composite materials within the heating frame to be achieved by closing the sealed door and using an industrial exhaust fan to draw air from the interior of the composite box. The gas enters through two material inlets and exits through the air guide frame. During the exhaust process, the gas is filtered through an activated carbon filter plate in the exhaust port, thereby reducing the concentration of potentially harmful gases in the workshop, minimizing the risk of workers inhaling harmful substances, and protecting the health and safety of operators.

[0025] Please see Figure 1 A magnetic block 25 is fixedly connected to the upper side of the composite box 1. The lower side of the magnetic block 25 cooperates with one side of the sealing door 15. When the sealing door 15 is opened, it can be temporarily fixed by adsorption between the magnetic block 25 and the magnetic block 25. It can be separated from the magnetic block 25 by force.

[0026] An expansion block 7 is fixedly connected to one side of the composite box 1. An electric telescopic cylinder 8 is fixedly connected to the expansion block 7. A combination plate 9 is fixedly connected to the output end of the electric telescopic cylinder 8. Two pressure sensors 10 are fixedly connected to the lower side of the combination plate 9. A force-generating block 11 is fixedly connected to the lower side of each of the two pressure sensors 10. A spring 12 is fixedly connected to the lower side of each of the two force-generating blocks 11. A U-shaped frame 13 is fixedly connected to the lower side of the spring 12. A contact roller 14 is rotatably fitted to the inner wall of the U-shaped frame 13. A sealing door 15 is rotatably fitted to one side of the composite box 1. An air extraction assembly 16 is provided on the lower side of the composite box 1.

[0027] Please see Figure 4 The exhaust assembly 16 includes an industrial exhaust fan 161 fixedly connected to the composite box 1, an air guide frame 162 fixedly connected to the output end of the industrial exhaust fan 161, a pull-out port 163 opened on one side of the air guide frame 162, and an activated carbon filter plate 164 disposed on the inner wall of the pull-out port 163. The air guide frame 162 cooperates with the winding component 6. During the heating process of the heating frame 2 heating the flowing composite material, the industrial exhaust fan 161 can be used to extract air from the interior of the composite box 1 by closing the sealing door 15. The gas enters from the two material ports 4 and exits from the air guide frame 162. During the exhaust process, the gas is filtered by the activated carbon filter plate 164 in the pull-out port 163, thereby achieving a certain degree of filtration of potentially harmful gases, reducing the concentration of harmful gases in the workshop, reducing the risk of workers inhaling harmful substances, and protecting the health and safety of operators.

The situation inside the composite box 1 can be easily observed through the high-temperature resistant transparent plate 22 in the observation port 21. The high-temperature resistant transparent plate 22 can be a high-temperature resistant transparent plate.

[0031] The implementation principle of a laminating machine for producing food packaging bags according to an embodiment of this application is as follows: When in use, the equipment is first placed in the corresponding position, and the internal drive component is connected to the corresponding power supply.

The inner wall of the heating frame 2 is provided with a heating mechanism. The substrate is laminated together by heating. After lamination, the laminated packaging bag is discharged from the material outlet 4 on the right side and is wound up by the support block 5. The support block 5 guides the moving laminated packaging bag.

[0032] The electric telescopic cylinder 8 pushes the combined plate 9 downward, pushing the contact roller 14 to contact the upper side of the composite material. When the material is stably wound by the winding component 6, the contact roller 14 is in a stable state. When the composite material has protrusions, the thick part will exert a reaction force on the contact roller 14. The compression spring 12 exerts force on the force block 11, and then the data is displayed from the pressure sensor 10. The pressure sensor 10 can be connected to the corresponding alarm device. When the value changes to a certain extent, an alarm can be issued to facilitate the monitoring of the flowing composite plastic and ensure the quality of the composite material.

[0033] During the heating process of the flowing composite material in the heating frame 2, the air inside the composite box 1 can be drawn out by the industrial exhaust fan 161 through the closed sealing door 15. The gas enters from the two material ports 4 and is discharged from the air guide frame 162. During the discharge process, it is filtered by the activated carbon filter plate 164 in the pull-out port 163, so as to filter the potentially generated harmful gases to a certain extent, reduce the concentration of harmful gases in the workshop, reduce the risk of workers inhaling harmful substances, and protect the health and safety of the operators.

[0034] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application.
