In line with the development needs of the industry, China JWELL Efficient pet sheet extrusion line came into being in the field of extruders. Different products have different needs, and their host structures are also very different. They are often used in different products, such as pelletizing, compounding, injection molding, blow molding, blown film, plate, sheet, etc. As we all know, in the field of PET sheet, the traditional host form is a single screw extruder. However, twin-screw main engines have long been common in China, and the proportion of related market fields has far exceeded that of single-screw main engines. With the continuous deepening of the concept of environmental protection, the available recycled materials have also been reused effectively and with high quality. Different types of materials have different characteristics, which puts forward higher requirements for equipment.
Composition of Efficient pet sheet extrusion line
China Efficient pet sheet extrusion line extrusion system includes screw, barrel, hopper, die, and die, plastic is plasticized into a uniform melt through the extrusion system, and under the pressure established in this process, the screw is continuously extruder head.
(1) Screw: It is the most important part of the extruder. It is directly related to the application range and productivity of the extruder. It is made of high-strength and corrosion-resistant alloy steel.
(2) Barrel: It is a metal cylinder, generally made of alloy steel with high heat resistance, high compressive strength, strong wear resistance and corrosion resistance or composite steel pipe lined with alloy steel. The barrel cooperates with the screw to realize the pulverization, softening, melting, plasticizing, exhausting and compacting of the plastic, and continuously and uniformly convey the rubber material to the molding system. Generally, the length of the barrel is 15 to 30 times its diameter, so that the plastic can be fully heated and fully plasticized.
(3) Hopper: The bottom of the hopper is equipped with a cut-off device to adjust and cut off the material flow, and the side of the hopper is equipped with a sight hole and a calibration metering device.
(4) Machine head and mold: The Efficient pet sheet extrusion line head is composed of an alloy steel inner sleeve and a carbon steel outer sleeve, and a forming mold is installed in the head. The role of the China Jwell pet sheet extrusion line head is to convert the plastic melt in the rotating motion into parallel linear motion, evenly and smoothly introduce it into the die sleeve, and give the plastic the necessary molding pressure. The plastic is plasticized and compacted in the barrel, and the porous filter plate flows into the molding die of the die through the neck of the die along a certain flow channel. A continuous and dense tubular cladding layer is formed around the core wire.
Efficient pet sheet extrusion line performance
- Double exhaust structure design, no need to dry, reduce energy consumption.
- The raw materials of China Efficient pet sheet extrusion line have higher applicability, whether it is ordinary APET, low-temperature PETG, or high-temperature resistant CPET, all have high plasticizing ability, and can use 100% recycled materials completely.
- The unique "one-key acceleration" function allows the equipment to realize low-speed adjustment and high-speed production, which greatly reduces the waste of raw materials caused by the adjustment process.
- The intelligent advanced control system, the network transmission speed is fast, the transmission error of information is greatly reduced, and the speed, pressure and material transportation of the equipment are more stable; the efficient and stable control system is supported, and the line of 1-80m/min can be realized. speed.
- China Jwell as a manufacturer of extruder, its winding part adopts servo control, which is more accurate, and has the speed synchronization function with the whole machine, which makes the winding more convenient, simpler and safer. The self-developed automatic rewinding machine can realize the simultaneous rewinding of all two and all three, which is safer and more efficient.
- The whole set of Efficient PET/PLA Environmental Sheet Extrusion Line adopts the international first-line brand-Siemens frequency conversion servo control and Ethernet conduction technology control to achieve high efficiency, high precision, high stability and high security. Quickly locate errors and enable remote maintenance when equipment fails. Channel-level diagnosis and error analysis can be achieved through HMI, which greatly reduces debugging and production downtime. The highly digitalized system makes commissioning easier and maintenance more convenient.
- Complete after-sales service system, China Jwell as manufacturer of extruder from equipment installation and commissioning to high-quality product manufacturing, and provides life-long technical support, so that customers have no worries.
Precautions for using pet sheet extrusion line
China Jwell as manufacturer of extruder, pet sheet extrusion line is a common plastic machinery equipment, in the process of daily operation of the extruder, pay more attention to the following, so as not to affect the use of the extruder.
The pet sheet extrusion line should run forward to avoid reversal.
Do not run on an empty stomach, you must heat the machine to feed and run, so as to avoid the phenomenon of sticking bars (holding the shaft).
It is strictly forbidden to enter the iron and other miscellaneous objects in the feed port and vent hole of the Efficient pet sheet extrusion line, so as to avoid accidents and affect production.
Safe use of electricity, grounding wire.
It is forbidden to touch the rotating parts such as the feeding port, the discharging port, the belt and the gear when the machine is running.
Lubricating oil should be injected into the China Jwell machine before use to avoid damage to the machine.
