Production process and principle of convenient bag film blowing machine:
Dry polyethylene particles are added to the lower hopper, and the weight of the particles themselves enters the screw rod from the hopper. When the particles are in contact with the oblique edges of the thread, they are rotated
The inclined edge of rotation generates a thrust perpendicular to the inclined edge in front of the plastic, pushing the plastic particles forward.
The friction between the plastic and the cylinder, as well as the collision and friction between particles, also gradually melt due to the external heating of the cylinder. Molten plastic warping machine
The head is filtered to remove impurities from the die head and the die mouth. It is cooled by the air ring, blown and expanded through the miter plate, pulled by the roller, and rolled to roll the finished film into a cylinder.
Convenient bag plastic film blowing machine main structure:
It is mainly composed of extruder, tee, die head, cooling device, herringhead, traction roller, winding device and so on.
1: extruder, extruder is mainly composed of screw, barrel feeding hopper, deceleration and drive motor, drive motor adopts frequency conversion speed regulation, through the belt transmission
The motor drives the reducer to make the screw rotate in the barrel. So that the hopper plastic particles in the external heating of the case of plastic melting through three
The filter is extruded from the die head and die mouth
2: three-way, by the filter net, filter plate, three-way gland three parts
3: die head
4: cooling device, composed of cooling air ring, air pipe, centrifugal fan, etc
5: traction, mainly composed of traction frame, herringbone, traction roller, winding machine and traction motor
6: electrical control part, the general unit is equipped with the unit operation cabinet, by the main button to turn on the main power supply, turn on the motor main switch, respectively through the button switch Control the electric heating of the fuselage, three-way, and each section of the mouth mold, among which the key parts are heated by thermocouple automatic temperature measurement and automatic temperature control, during the normal production process, temperature
Degree can be controlled automatically to ensure the stability and reliability of the production process.
