Today we will give a detailed introduction to the stone paper production line of blown film technology.
The principle of blown film technology for stone paper production line:
The granules manufactured by the granulator are transported to the barrel of the machine, with quantitative screw for expected entrance, the electric heating and a strong push to squeeze and screw, make the raw material granules temperature rise and soften up to 160 ℃, and with melted PE material, squeezed into the "O" shape mold cylinder material, after compressed air to blow up, under the action of cold wind and the structure of the bubble shaping machine, a stable stone paper paper cylinder is formed, after cutting off the ear material on both sides and winding it,two stone paper rolls are collected at the same time.
After coating the base paper produced by the equipment, the product can be used for writing, printing, making books, magazines, notebooks, advertising brochures and other products.

Content |
|
Feeder system |
Negative pressure suction device, storage barrel, metering feed mechanism, automatic feed PLC control program. |
| Screw |
diameter 120 single screw, L/D 36:1, screw material: 38CrMoALA high quality alloy steel, surface nitride treatment, nitride depth of 0.6mm, surface hardness HV is greater than 950.The heating segment of the main screw is seven sections.
|
|
Gear box |
Gear box 2-level drive precision hard grinding surface teeth;Inclined gear material (fine grinding) 20 chrome manganese carburizing treatment. |
|
Motor |
Main extruder is 110kw 4 class 380V 50HZ, 6 group C belt |
|
Mold |
Single layer O shape rotary mold head, with diameter 120mm, 42CrMo，channel electroplated hard chromium 0.03-0.04mm and mirror polishing. Mold clearance adjustment adopts push-pull fine tooth screw adjustment, mold head clearance is 3mm, automatic temperature control.Heating method: aluminum heating ring heating. |
|
Automatic air supply and stabilizer |
During the blowing process, the air leakage could make the film narrow, then the transducer close to the film will feedback this signal to main controller, and open the electromagnetic valve to feed air to mould, with the alarm, until the film’s width is regular, then close the electromagnetic valve without alarm. |
|
Traction splint |
Including traction roller, guide roller, etc., can eliminate traction wrinkles, improve the cooling effect of membrane bubble. |
|
The cutting |
Includes traction roller, guide roll, roll, split device and other parts |
|
Thickness gauge |
The thickness and thickness deviation of the paper can be shown in the thickness and thickness deviation of the paper. The data can be provided to the operators for the thickness adjustment. |
|
Winding machine |
Adopt double station center to collect roll, roll up roll of the biggest roll diameter 1000mm, 6 inch gas shaft , adopt constant tension control system |
