Look at the machinability of PE film blowing machine

Release date:2019-06-03 00:00 Source: Click:

  PE film blower pushes the plastic particles forward. During the pushing process, the friction between plastic and screw, between plastic and barrel, as well as the collision friction between particles, and gradually melts due to the external heating of barrel. The melted plastics are filtered through the die head to remove impurities from the die mouth, cooled by the wind ring, blown through the herringbone, and rolled by the traction roll to roll the finished film into a cylinder. Frequency converter of film blower.


  Cooling device, foam stabilizer, herringbone, traction roll, coiling device and other components.1: Extruder, extruder is mainly composed of screw, barrel feeding hopper, deceleration and drive motor, drive motor adopts electromagnetic speed regulating motor (also can be used frequency conversion ordinary motor), drive reducer through belt drive to make the screw rotate in the barrel; new material is blown out with brand-new particles, color and luster. All weights are clean and the bag stretches well.


  Others use recycled plastic bags to make particles, which are generally called used materials. When they are made into particles, they are usually grey. When they are made into bags, they usually need to add pigments. The bags are uneven in color, brittle and fragile, and the price is low. And high temperature resistance, high temperature deformation; wear resistance, long life; corrosion resistance, material corrosion; high strength, can withstand large torque, high speed;

It has good cutting performance, small residual stress and small thermal deformation after heat treatment. If it can meet the user's requirements for bubble, crystal point, dyeing uniformity and so on. 3. Plastic quality of screw: 1) Whether the melt temperature of screw extruded is uniform, axial fluctuation and radial temperature difference, so we always hope for a good screw.


  Its adaptability and high plasticizing efficiency should be combined. What is the diameter of the barrel, divided by the cross-section diameter of the die, and the book is the multiple of blowing film. For example, the width of the plastic is 650mm. The calculation method is as follows: 650 *2 = 1300 (to get the expansion number) 1300/3.14 = 414? (Calculate the diameter of the diaphragm tube) 414/200 (diameter of the cross section)=2.07 to get the multiple of the blowing ratio.
