Description

Technical Field

[0001] The invention belongs to the technical field of flexible packaging production, and in particular relates to solvent-free composite equipment and a composite method for flexible packaging. Background Art

[0002] With the rapid development of modern industrial technology, flexible packaging materials have been widely used in food, medicine, cosmetics and other industries. These industries have increasingly higher requirements for flexible packaging materials, which not only require them to have excellent barrier properties, temperature resistance, aesthetics and lightness, but also need to meet strict hygiene and safety standards.

[0003] The existing mainstream laminating machines are mainly divided into dry laminating machines and wet laminating machines, among which: dry laminating machines are machines that use dry laminating processes to stick different plastic films together to form composite films. The dry laminating process is to fully dry the solvent in the glue liquid by heating and exhausting it after gluing, and then compound it in a "dry" state; the so-called wet laminating machine is a machine for producing composite materials based on paper, and is the mother machine for producing composite materials such as paper and plastic film, paper and aluminum foil, and paper and paper. It is different from the dry laminating machine, which first applies glue on one of the materials, then enters the drying box to volatilize the excess solvent, and then compounds with another material after only glue is left. The working principle of the wet laminating machine is to apply glue on one material, immediately press it together with another material after applying glue, and then enter the drying box for drying and forming.

[0079] Step 5: Then the glued adhesive material is passed through the drying part 5 to dry the glued surface;

[0080] Step 6: The dried adhesive material and the adhesive material are passed through the interior of the joint 6 and extruded and combined together to form a finished product;

[0081] Step 7: Then fix the finished product and the reeling feeding part 2 with load-reeling function, and drive the reeling material seat to rotate to reel the finished product, thereby completing the production of the flexible packaging raw material.

[0082] The working principle of the present invention is as follows: when the raw materials for flexible packaging need to be produced, the pasting material, pasted material and the rolling material seat need to be installed inside the corresponding feeding part 2, and then the control part 7 first controls the fixed motor 207 to drive the fixed screw 206 to rotate, so that the fixed screw 206 drives the clamping seat 202 and the fixed seat 203 to move in the direction of the corresponding pasting material, pasted material and the rolling material seat through the thread transmission until the corresponding pasting material, pasted material and the rolling material seat are fixed, so as to avoid the corresponding pasting material, pasted material and the rolling material seat from being offset during the rotation process;

[0083] Then, the driving motor 205 drives the sliding rod 204 to rotate, and the rotation of the sliding rod 204 drives the corresponding fixing seat 203 to rotate, and the fixing seat 203 drives the corresponding pasting material, pasted material and winding material seat to rotate in corresponding directions, so as to realize the release and winding operations of the material;

[0084] Then the pasting material and the pasted material are passed through the corresponding correcting part 3, and the correcting part 3 monitors the transportation status of the material in real time and sends the monitored data to the control part 7 for processing. The control part 7 controls the inclination angle of the correcting part 3 to drive the material inside to adjust its posture to ensure that the material is always in the center position;

[0085] Then the adhesive material continues to pass through the corresponding adhesive adding part 4, and the adhesive material is evenly coated with glue on one side through the adhesive adding part 4;

[0086] Then the glued pasted material is passed through the drying part 5 to dry the glued surface. Drying the glued pasted material can ensure the quality of the composite. Water and impurities can be removed by drying, providing good conditions for subsequent steps.

[0087] Then, the dried glue-coated material and the bonded material are passed through the interior of the combining part 6 for extrusion and combination, and the glue-coated material and the bonded material are combined together by extrusion to form a finished raw material for flexible packaging; then, the finished product is fixed to the winding feed part 2, and the winding material seat is driven to rotate by the feeding part 2 responsible for the winding function to wind up the finished product, thereby completing the production of the flexible packaging raw material.

[0088] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
