Description

Technical Field

[0001] This utility model relates to the field of packaging bag composite processing, specifically a rapid composite equipment for food packaging bags. Background Technology

[0002] Composite processing of food packaging bags involves combining two or more materials (such as plastic, paper, metal foil, etc.) into a multi-layered structure through a composite process, forming an inseparable whole packaging material.

[0003] In existing technologies, during the lamination process of packaging bags, the two materials are fed and extruded, and due to the relatively light texture of the materials, they shake during feeding, causing misalignment and displacement when the two materials are laminated, which affects the quality of the lamination process. Furthermore, when the finished product is wound up, gaps are generated between layers as the winding thickness increases. Therefore, a rapid lamination device for food packaging bags is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, during the lamination process of packaging bags, the two materials are fed and extruded, and due to the relatively light texture of the materials, they shake during feeding, which affects the alignment of the two materials during lamination and causes misalignment, affecting the quality of lamination. Furthermore, when the processing is completed and the bags are rolled up, gaps between layers are generated as the thickness of the roll increases. This utility model proposes a rapid lamination device for food packaging bags.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A rapid lamination device for food packaging bags, comprising a base; a main equipment cabinet is provided on one side of the top of the base; an A feeding roller and a B feeding roller are respectively provided on one side of the top of the main equipment cabinet; an A motor for driving the A feeding roller and the B feeding roller is provided inside the main equipment cabinet; a pressure roller is provided in the middle of the side of the main equipment cabinet; a B motor for driving the pressure roller is provided inside the main equipment cabinet; a winding roller is provided on one side of the bottom of the main equipment cabinet; and a fixing plate is provided on the side of the main equipment cabinet above the winding roller. A U-shaped plate is connected to the bottom of the fixed plate, and a sliding rod is slidably connected to the U-shaped plate. A spring is sleeved on the sliding rod, and a horizontal plate is connected to the bottom end of the spring. A rubber roller is movably connected to the bottom of the horizontal plate through a side plate. A support plate is provided on the other side of the top of the base. Support blocks are provided on the back of the support plate and the main equipment cabinet. An electric telescopic rod and a connecting plate are provided on the top of the support block. A rocker arm is rotatably connected to the side of the connecting plate. A roller is movably connected to one end of the rocker arm. A limit groove is opened at the bottom of the rocker arm. A U-shaped clamp is movably connected to the top of the electric telescopic rod, and the two sides of the U-shaped clamp are slidably connected to the inside of the limit groove.

[0006] Preferably, the other ends of the A feed roller and the B feed roller, as well as the other ends of the pressure roller and the winding roller, are rotatably connected to the side of the support plate.

[0007] Preferably, the inner bottom surface of the U-shaped plate has a directional hole, the slide rod is slidably connected inside the directional hole, and the spring is coaxially arranged with the directional hole.

[0008] Preferably, the rubber roller is located directly above the roll, and the side plates are provided at the bottom of both ends of the cross plate.

[0009] Preferably, the top of the support block is provided with the electric telescopic rod, and the top of the support block is also provided with the connecting plate.

[0010] Preferably, the rocker arm has limiting grooves on both sides of its bottom, and the two sides of the U-shaped clamp are slidably connected to the inside of the limiting grooves.

[0011] The advantages of this utility model are: 1. This utility model achieves continuous and adaptive pressing of the material being wound on the roll by setting up an elastic pressing mechanism consisting of a U-shaped plate, a sliding rod, a spring, a horizontal plate, and a rubber roller. As the winding diameter increases, the rubber roller can automatically float upward under the push of the spring, thereby always maintaining the pressing force on the surface of the roll material. This effectively solves the problem of interlayer gaps caused by the increase in winding thickness, greatly improves the compactness and stability of the finished roll, and avoids loosening during transportation and storage. 2. This utility model achieves precise and flexible control of the tension along the feeding path by setting up a feeding tension adjustment mechanism consisting of an electric telescopic rod, a rocker arm, a limiting groove, a U-shaped clamp, and a roller. Through the telescopic movement of the electric telescopic rod, the U-shaped clamp is driven to slide within the limiting groove of the rocker arm, thereby precisely controlling the lifting height of the roller at one end of the rocker arm. This adjusts the tension amplitude and wrapping angle when the packaging bag is fed, solving the problem of easy shaking and displacement of lightweight materials during feeding, which leads to misalignment in the composite process. This significantly improves the alignment accuracy and product quality of the composite processing. Attached Figure Description
