Description

Technical Field

[0001] The utility model relates to the technical field of packaging composite film production, in particular to packaging composite film printing equipment. Background Art

[0002] Packaging composite film refers to a film material formed by combining two or more different polymer materials under certain conditions. It possesses a variety of excellent properties, including barrier properties, heat resistance, cold resistance, water resistance, gas resistance, oil resistance, corrosion resistance, and wear resistance. Packaging composite film is widely used in packaging for food, pharmaceuticals, cosmetics, daily chemicals, and electronic products to protect product quality and extend shelf life. This material is manufactured through printing and lamination processes and is available in a variety of structures and materials.

[0003] The prior art publication number CN213198846U is a printing device for producing composite film for packaging bags, which includes a support leg and a first hydraulic column. A base is fixed to the upper end of the support leg, and a workbench is fixed to the upper end of the base. A first unwinding wheel is distributed on the left side of the base, and a winding wheel is distributed on the right side of the base. A support column is fixed to the upper end of the base, and a mounting seat is fixed to the upper end of the support column.

[0004] This device can print and laminate two layers of film, but in actual application, since it does not have a correction function, once the lower film or the upper film deviates during the unwinding process, it will cause the invalid area of ​​the edge of the composite film after bonding to increase, resulting in material waste. In severe cases, it may even require re-pasting, increasing manufacturing costs. Therefore, improvements are proposed. Utility Model Content

[0005] The utility model is a packaging composite film printing device proposed to solve the shortcomings in the prior art.

The unwinding roller adopts a detachable design, which is conducive to the installation of the lower film or the upper film on the winding roller.

[0011] Furthermore, the two lower pressure rollers each include two cylinders, and the cylinders are fixedly installed on the top of the frame. The movable ends of the two cylinders are commonly fixedly connected to the movable frame, and the movable frame is fixedly connected to the fixed plate. The inner walls on both sides of the movable frame are commonly rotatably connected to the pressure roller body, and the cylinder can control the lifting and lowering of the pressure roller body through the fixed plate.

The long seat has a limiting effect on the slider, which can ensure the stability of the slider movement.

[0013] Furthermore, the four pressure detection rollers all include a pressure sensor, and the pressure sensor is fixedly embedded on the inner wall of one side of the slider. The detection end of the pressure sensor is fixedly installed with a spring, and the other end of the spring is fixedly connected to a movable block. The bottom of the movable block is fixedly connected to the detection roller body. When the detection roller body is subjected to extrusion force, the pressure sensor will be squeezed through the movable block and the spring.

[0014] Furthermore, the movable block is slidably connected to the slider, and the slider has a limiting effect on the movable block, which can ensure the stability of the movement of the movable block.

The top centers of the two lower pressure rollers are fixedly connected to a fixed plate 3, and the bottoms of the two fixed plates 3 are installed with a two-way movable component. The two movable ends of the two two-way movable components are fixedly installed with a pressure detection roller. The two lower pressure rollers include two cylinders 11, and the cylinders 11 are fixedly installed on the top of the frame 1.
