Film blowing machine production process is firstly added polyethylene particles drying hopper, then particles by their own weight from the hopper into the screw thread, when the screw and the oblique edge contact, the rotation of the face of the plastic face aslant vertical thrust and aslant, the particle goes forward.
During the pushing process, the friction between plastic and screw and plastic and barrel, as well as the collision and friction between particles, is also due to the melting of plastics due to the external heating of the barrel. PE film blowing machine gear transmission is a transmission the most widely used in mechanical transmission, it is a set of gear teeth of the drive torque to drive back.
The function of the mixer and the opening machine is the same as the plastic mixing and plasticizing equipment. The difference between the mixer and the open mixer is that the mixing and plasticizing material of the mixer is closed. It has no disadvantages such as dust flying, manual operation and mixing time. Because mixer mixer has special structure form and mixing material in closed and high temperature mixing chamber, the mixer has shorter mixing and plasticizing time, more homogeneous raw material, better plasticizing quality and higher working efficiency compared with open mill.
PE film blowing machine mechanical equipment put into production after the use of.R to operate a year under normal conditions, need maintenance and replacement of parts (usually wearing parts): seal ring, gasket, coupling the elastic rubber ring and chain (small size), V belt, timing belt, bearing resistance the heater and the assembly is not reasonable or the inferior parts etc..
The PE blow moulding machine is made up of internal diameter, bushing or cast wear-resistant alloy. In order to save valuable alloy steel, the machine body of larger extruder is usually molded by key. Then, after finishing the inner hole, wear a wear-resistant alloy bushing or a wear-resistant alloy material.
