Description

Technical Field

[0001] The utility model relates to the technical field of sheet material processing, in particular to a sheet material cooling device of a multi-layer co-extrusion sheet material machine. Background Art

[0002] Multi-layer co-extrusion sheet machine is a kind of equipment used to produce multi-layer composite sheets. It usually consists of an extruder and a lamination die. During the production process, different kinds of raw materials are extruded through the extruder and stacked layer by layer through the lamination die to form a multi-layer composite sheet. These sheets can have different characteristics and functions, such as strength, wear resistance, heat insulation, etc. During the extrusion process, the raw materials are heated and extruded to form a plastic melt, which is then extruded through the die and cooled into a sheet. However, due to the friction, extrusion and heating during the extrusion process, a large amount of heat will be generated on the surface and inside of the sheet. If it is not cooled in time, the temperature of the sheet will be too high, so a cooling device is required.
