Plastic packaging film extrusion machine production
In the processing of plastic packaging film, it is usually first to turn the solid plastic resin into a melt through an appropriate method, and then use a certain method to shape the melt to become the required plastic packaging film to complete this There are many process equipment, one of which is the extrusion process. The extrusion process is mainly used to produce plastic packaging products such as film sheets and extrusion blown bottles. The equipment used is a plastic extruder.
1 Extruder and its auxiliary equipment
1.1 Extruder
The extruder is the main machine for forming plastic film products. According to the process conditions and characteristics of different plastic varieties, different extruder screw structures, extruder die and auxiliary machinery are selected to form an extruder production line to complete different varieties of plastic film Molding work.
The extruder has other functions.
¢ÙIt can continuously produce plastic products with fixed cross-section geometry, such as plates, tubes, profiles, wires, cables, packaging tapes, bars and nets.
¢ÚExtrusion is repeated periodically to produce hollow products, such as bottles, barrels and other hollow containers.
¢ÛOther uses. In the calendered film production line, the extruder plasticizes and filters the raw material of the calendered film in the previous process of the calender, and then supplies the calender for production and molding.
¢Ü Use an extruder for mixing and pelletizing, coloring and recycling waste plastic film pelletizing, etc.
¢ÝIt can be used in one machine for multiple purposes. It can extrude different types of plastic film by changing screws of different structures, changing the head die of different structures, and matching auxiliary machines to produce products of various shapes.

1.2 Production line composition of plastic film extruder
1.2.1 Host
The main engine of the plastic film extruder production line is the extruder. Its function is to plasticize powder or plastic particles in a molten state. There are many types of technology, such as single screw, twin screw, vented extruder and multi-screw extruder.
The mold. The plasticized melt is molded, and the plasticized plastic is molded according to the shape of the processed plastic product. According to the shape of the processed plastic product, the plasticized plastic is molded into a suitable cavity in the die of the machine head. Films of various shapes and sizes.
Cooling device. Further cool the shaped film.
Traction device. Clamping the plastic film, matching the flow rate of the extruder, pulling the film evenly, and transporting the film to the winding equipment.
Take-up device. An equipment that rolls the finished product into bundles when producing films.
Stacking device. The equipment is simple, and some are placed directly on the desktop cart and stored directly after testing.
