The main structure of the plastic recycling machine is mainly composed of extruder, die head, die head, cooling device, foam stabilization frame, herringbone plate, traction roller, cooling device, etc. So what is the frequency conversion application of plastic recycling machines? Let's take a look next.

Purpose of plastic recycle machine
Add the dried polyethylene particles into the lower hopper of the plastic recycling machine, and enter the screw from the hopper by the weight of the particles themselves. The plastic particles are pushed forward. During the pushing process, due to the friction between the plastic and the screw, the plastic and the barrel, the collision and friction between the particles, and the external heating of the barrel, it gradually melts. The molten plastic is filtered by the machine head to remove impurities and comes out from the die opening of the die head.
The plastic recycle machine extruder is mainly composed of the screw, barrel feeding hopper, deceleration, and driving motor. The driving motor adopts an electromagnetic speed-regulating motor (or common frequency conversion motor), and the speed reducer is driven by a belt drive to make the screw rotate in the barrel. The plastic granules in the hopper are extruded from the die opening of the die head through three-pass filtration under the condition of external heating.
The plastic recycling machine adopts the advanced spiral die structure. According to the particularity of high pressure, low pressure, mixed material, and recycled polyethylene materials, and comprehensive consideration, the main parameters such as helix angle, receding slope angle, shaping angle length, and die opening are designed. The technical parameters are selected and finalized after many comparative tests.
The cooling device of the plastic recycling machine consists of a cooling air ring, air duct, blower, etc.
It is composed of main components such as traction frame, herringbone board, traction roller, coiling mechanism, and traction motor.
Generally, the Film Blowing Machine is equipped with a unit operation cabinet. Press the main button to turn on the main power supply and turn on the main switch of the plastic recycling machine motor. The main body and tee, and the electric heating of each button of the die can be controlled by the sub-button switch respectively. The coil adopts thermocouple automatic temperature measurement and automatic temperature control. During the normal production process, the temperature can be automatically controlled to ensure a stable and reliable production process. There are many kinds of film blowing machines, such as PE, POF, and so on.
The new material is blown out with new particles, the color is uniform, clean, and the bag is stretched well. Some people also use recycled plastic bags to make particles. This kind of particle is generally called old material. When made into particles, it is usually gray. When making bags, pigments are usually added to make bags with uneven coloring, brittle, and easy to break, the price is also lower.
Although it is a recycled plastic bag, it is generally a waste bag in the bag-making process and there is still a big difference between garbage plastic in the usual sense.
Film Blowing Machine produces films suitable for all kinds of high-grade film packaging. This film can be widely used in light and heavy packaging due to its good barrier properties, preservation, moisture resistance, frost resistance, oxygen insulation, and oil resistance. Such as various fresh fruits, meat products, pickles, fresh milk, liquid beverages, medical supplies, etc.
