Classification and product application field of sumino film coating machine

Film coating machine, also known as extrusion compound machine, tape casting machine, extrusion tape casting machine, tape casting compound machine, plastic coating machine and coating compound machine, is a kind of extrusion molding machinery. It has the advantages of high degree of automation, simple operation, high production speed, uniform coating thickness, high adhesion fastness, flat coiling, environmental protection and no pollution, saving labor and raw material costs. In fact, small equipment with a width of about one meter by pouring oily liquid on the surface of photos and canvases is the real "film pouring" machine, which is generally used in studios and other industries, and belongs to small machinery for daily life. The composite material production line with high speed and large width belongs to light industrial machinery, which should be called extrusion casting composite unit according to the industry standards of packaging, printing and machinery manufacturing. At present, Nanjing Zhuye Seiko Machinery Co., Ltd. sells film coating machines on major B2B platforms.

Main functions of film coating machine

Small film coating machine is a special equipment for film coating such as photos and packaging

The large-scale film coating unit is used for making paper plastic composite films. It is an equipment for single-layer film coating and double-layer film coating on high-pressure polyethylene (LDPE), OPP film, paper cup paper, carton paper, trademark paper, melon seed bag paper, cleaning bag paper, aluminum foil, film, cloth and other substrates.

Process principle

Extrusion tape casting: plastic particles are plasticized by the screw and extruded into a linear shape from the die mouth of the flat die. After stretching, they are attached to the surface of flexible substrates such as paper, film, non-woven fabric and woven fabric, cooled, shaped and pressed to form a composite material with both the barrier and heat sealing properties of the plastic film layer, the strength, toughness and functional properties of the substrate.

Structural composition

The whole machine is composed of feeding device, extruder host, die, unwinding mechanism, compound mechanism, winding mechanism, edge position control device, edge cutting device, heating and cooling system, electrical measurement and control system, etc. According to the needs of different products, the second unwinding mechanism, printing equipment, oven, substrate surface treatment device (Corona machine, etc.), on-line thickness gauge and other components can be added. Previous process equipment: granulator, printing press or other equipment; Equipment for subsequent process: Slitter or other equipment.
