PLA sheet extrusion line
Polylactic acid, also known as polylactide, belongs to the polyester family. Polylactic acid is a polymer obtained by polymerization with lactic acid as the main raw material, which is usually called corn plastic. It has sufficient sources and can be regenerated. It is a new type of biodegradable polyester material mainly made from L-lactic acid produced by corn and cassava through polycondensation, cracking, purification, polymerization and other technological processes. The production process of polylactic acid is pollution-free, and the products can be biodegradable to realize the circulation in nature. Therefore, it is an ideal green polymer material, and it is also a high-tech environmental protection product encouraged by the state. It is widely used in the fields of electronic product shells, auto parts, medical devices, clothing fibers, agricultural mulch, food packaging, tableware and so on.
Gwell mechanical PLA sheet extrusion production line is applicable to the production of PLA (polylactic acid) and modified PLA. PLA (polylactic acid) is derived from plant resources and can be directly used for extrusion molding. PLA and hydrolytic PLA are widely used in various food packaging and hardware packaging because of their biodegradable, compostable, recyclable and other characteristics Equipped with melt metering pump for quantitative extrusion, speed and pressure closed-loop control, so that the thickness of the sheet is uniform. The roller drives independently, and the linear speed of each roller is controlled synchronously. The whole machine is controlled by PLC, and the actual parameter setting, data calculation, feedback, alarm and other functions are automated
Multi extruder coextrusion technology can be used to produce multi-layer coextrusion composite PLA or starch sheets, which are widely used in thermoforming, printing, hardware packaging, etc.
*Equipped with precision distributor, the layer is uniform, the proportion of each layer is adjustable, and the digital control accuracy.
*Inclined horizontal tablet pressing structure makes operation and maintenance more convenient.
*The roller is powered independently, and the linear speed and the extruder speed are controlled synchronously in a closed loop.
*The whole machine adopts PLC control to realize the automatic control of parameter setting, data calculation, feedback, alarm and other functions.
*The electrical control system and operating procedures are independently prepared by Gwell
