Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the apparatus for preparing a composite packaging film is used for laminating two layers of films together, and includes a first discharging roller 1, a film laminating machine 2, a second discharging roller 3 and a material receiving roller 4;

the first discharging roller 1 is arranged on one side of the film coating machine 2, and the second discharging roller 3 and the material receiving roller 4 are arranged on the other side of the film coating machine 2;

the film laminating machine 2 comprises a composite mechanism 5, a film laminating unit 6, a first arc-shaped flattening roller 7 and a second arc-shaped flattening roller 8, wherein the film laminating unit 6 is arranged above the composite mechanism 5;

the first arc-shaped flattening roller 7 is arranged between the first discharging roller 1 and the compound mechanism 5, and the second arc-shaped flattening roller 8 is arranged between the compound mechanism 5 and the second discharging roller 3.

The composite packaging film preparation device is suitable for pouring PE melt between the PE woven film 9 and the aluminized PET film 10, and then compounding the PE woven film 9 and the aluminized PET film 10 together. The first blowing roller 1 comprises an air expansion shaft for placing a material roll of the PE braided film 9. When the PE braided film 9 is pulled, the first discharging roller 1 rotates passively, the tension is controlled by the magnetic powder tension controller, and the PE braided film 9 is continuously released. The second lay-off roll 3 also contains an air-lift shaft for placing the roll of aluminized PET film 10. The second discharging roller 3 passively rotates, and the magnetic powder tension controller is also used for controlling the tension, so that the aluminized PET film 10 is continuously released to the film laminating machine 2. The material receiving roller 4 is an air expansion shaft, can rotate under the drive of a motor and is used for rolling the composite film.

The PE woven film 9 and the aluminized PET film 10 respectively enter the compounding mechanism 5 from the upper part, and meanwhile, the film spraying unit 6 extrudes PE melt between the PE woven film 9 and the aluminized PET film 10, so that the PE woven film 9 and the aluminized PET film 10 are bonded together by the PE melt to form a composite film after being pressed by the compounding mechanism 5.

Referring to fig. 1, before the PE woven film 9 and the aluminum-plated PET film 10 enter the combining mechanism 5, they are respectively flattened by a first arc-shaped flattening roller 7 and a second arc-shaped flattening roller 8. When the film passes through the arc flattening roller, the film is subjected to a transverse force, and the transverse force plays a flattening role to prevent the film from being wrinkled.

In some embodiments, referring to fig. 2, the first arc-shaped flattening roller 7 and the second arc-shaped flattening roller 8 have the same structure, and the first arc-shaped flattening roller 7 includes a fixed arc-shaped core shaft 11 and an arc-shaped rubber sleeve 12 which is sleeved on the arc-shaped core shaft 11 and can rotate. When the arc flattening roller runs, the arc core shaft 11 does not rotate, and the arc rubber sleeve 12 on the surface rotates. When the film passes through the arc flattening roller, a transverse force is generated, and the transverse force plays a flattening role on the film.

In some embodiments, referring to fig. 1, the compounding mechanism 5 includes a compounding roller 13 and a compaction roller 14 parallel to the compounding roller 13. The PE woven film 9 enters the laminating mechanism 5 from above against a compacting roller 14, and the aluminized PET film 10 enters the laminating mechanism 5 from above against a laminating roller 13. The PE woven film 9 and the aluminum-plated PET film 10 pass between the compacting roller 14 and the composite roller 13, and are pressed together by the compacting roller 14 and the composite roller 13.

In some embodiments, referring to fig. 1, the laminating unit 6 includes an extrusion die 15, and the extrusion die 15 has a strip-shaped die lip, and the length direction of the die lip is parallel to the compounding roll 13. The extrusion die 15 is aligned with the film material between the compaction roller 14 and the composite roller 13, and PE melt sprayed by the extrusion die 15 is just sprayed on the PE woven film 9 and the aluminized PET film 10.

In some embodiments, referring to fig. 1, the laminating unit 6 further comprises a hopper 16, a heating chamber 17, and an extrusion mechanism 18. The hopper 16 contains PE particles which are heated in a heating chamber 17 and the molten PE melt is extruded by an extrusion mechanism 18 towards an extrusion die 15. The extrusion mechanism 18 is a screw extrusion mechanism.

In some embodiments, referring to fig. 1, the second discharge roll 3 is disposed obliquely above the compounding mechanism 5.

In some embodiments, referring to fig. 1, a pressing roller unit 19 is further disposed between the film coating machine 2 and the material receiving roller 4, and the pressing roller unit 19 includes two parallel and close round rollers. Before the material is received, the roll change can be realized without stopping by opening the compression roller unit 19 during roll change.

In some embodiments, referring to fig. 1, a deviation rectifier 20 is disposed between the first discharging roller 1 and the laminating machine 2. The deviation rectifying device 20 can prevent the PE braided film 9 from deviating.

In some embodiments, referring to fig. 1, a first guide roller 21 is disposed outside the film laminating machine 2, the first guide roller 21 is located between the first discharging roller 1 and the film laminating machine 2, a second guide roller 22 is disposed below the first guide roller 21, a third guide roller 23 is disposed in the film laminating machine 2, and the third guide roller 23 is lower than the first guide roller 21 and the second guide roller 22. The PE woven film 9 extends downwards from the first discharging roller 1, then extends forwards to the second guide roller 22, extends upwards after passing below the second guide roller 22, then extends downwards obliquely to the third guide roller 23 after passing above the first guide roller 21, extends upwards obliquely after passing below the third guide roller 23, passes through the first arc-shaped flattening roller 7, and finally enters the compound mechanism 5. The PE knit film 9 passing through the above-described feeding path is sufficiently tensioned before entering the first flattening roller 7.
