Stretching film microwave dryer machine uses stretching film/winding film as packaging material and applies to pallet/pallet package.Loading, The rotation of the turntable drives the goods to rotate and pack the regular or irregular goods. The shrinkage and self-stickiness of the stretching film bind the goods and pallets to a whole and play a fixed role, so that the goods will not collapse and bulk, and can also play a role in preventing dust, moisture and damage.
Stretching film microwave dryer machine is more suitable for the packaging of single or multiple small-sized goods. Although the machine itself has a certain load range, it adapts to the packaging requirements of goods in bulk storage and transportation, at the same time reduces labor intensity and improves work efficiency. Thus, it is widely used in packaging enterprises, and it is an ideal equipment for product packaging in modern enterprises.
Plastic extruder is divided into twin screw extruder and single screw extruder.The difference between the two extruders: single-screw machine and double-screw machine: one is a screw, one is two screw. Are driven by a motor. The power varies with the screw. The power of 50-cone pairs is about 20kW, and that of 65kw is about 37kW. The output is related to the material and screw. The output of 50-cone pairs is about 100-150kg/h, and that of 65-cone pairs is about 200-280kg/h. The output of a single screw is only half. Extruders can be divided into single-screw, double-screw and multi-screw extruders according to the number of screws. At present, single screw extruder is widely used and suitable for extrusion of general materials. Double-screw extruder has less heat generated by friction, the shear of materials is more uniform, the screw transport capacity is larger, the extruder is more stable, the material stays in the barrel for a long time, mixed evenly. The development of single screw extruder is mainly marked by the development of its key component - screw. From the perspective of single-screw development, although single-screw extruder has been more perfect, but with the continuous development of polymer materials and plastic products, there will be more characteristics of new screw and special single-screw extruder. In general, single-screw extruder is developing towards high speed, high efficiency and specialization.
