Description
Technical Field
The utility model relates to an aluminum-plastic panel composite sheet production facility.
Background
The existing aluminum-plastic plate is structurally characterized in that an upper aluminum alloy plate and a lower aluminum alloy plate are adhered to a PE plastic layer, the PE plastic layer is formed by mixing, melting and extruding a high-grade PE reclaimed material and a low-grade PE reclaimed material in a production process, and the extruded PE plastic layer has poor chromaticity and poor brightness after the low-grade PE reclaimed material and the high-grade PE reclaimed material are mixed, so that the adhesion degree of the PE plastic layer and the aluminum alloy plate is greatly influenced; in order to change the chromaticity, the brightness and the adhesion degree of the plastic layer, a plastic layer of a high-grade PE reclaimed material wrapping a low-grade PE reclaimed material is designed, and the plastic layer with the structure needs corresponding production equipment to realize.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an aluminum-plastic panel composite sheet production facility aims at solving the production problem of the aluminum-plastic panel of the plastic layer of the PE reclaimed material of a high level parcel low level.
The utility model provides an aluminum-plastic panel composite sheet production facility, including first extruder, the second extruder, forming die, rubber coating device and metal sheet combined mechanism, the discharge end of first extruder and second extruder is provided with crowded composite distributor altogether, forming die sets up in crowded composite distributor's discharge end altogether, rubber coating device and metal sheet combined mechanism set gradually in forming die's discharge end, first extruder and second extruder are connected the melting PE material of two kinds of different regeneration levels behind the crowded composite distributor altogether and are carried out the layering and extrude, and pass through rubber coating composite aluminum plate formation aluminum-plastic panel again after forming die shaping, and simple production is easy, and the material cost is reduced, the original structure of aluminum-plastic panel has been changed, make the colourity of plastic layer, luminance and adhesion degree have great promotion.
In one or more embodiments, the first extruder is a single screw extruder.
In one or more embodiments, a high regeneration grade PE material is placed in the first extruder.
In one or more embodiments, the second extruder is a twin screw extruder.
In one or more embodiments, a low regeneration grade PE material is placed in the second extruder.
In one or more embodiments, a protective film combining mechanism is further arranged behind the metal plate combining mechanism, and the protective film combining mechanism combines a protective film on the surface of the metal plate to form protection.
The utility model has the advantages that: first extruder and second extruder are connected and are crowded the melting PE material of two kinds of different regeneration levels behind the composite distributor altogether and carry out the layering and extrude to form the plastic-aluminum board through rubber coating composite aluminum plate again after the shaping of forming die, production is simple easy, reduces raw materials cost, has changed the original structure of plastic-aluminum board, makes colourity, luminance and the adhesion degree of plastic layer have great promotion.
