JM55X2+65X1600 Three-layer horizontal roll draft film blown production line is esssentially composed of three main engines. Rolating haul-off is composed of  BQ1600 rolating haul-off machine and BJ1600 double winder machine. This machine’s total power is about 95KW, when the nomal operation of the actual power is about 60-80KW, circuits, waterway, gas circuit system are complete.

2, Die head/ Air ring (Taiwan) (with 3 quick-change filter screen devices)

(1) Specification: PE:  300 mm

(2) Die gap  1.2

(3) Material: 40cr, full flow plated hard chromium and surface polishing

(4). Heating power: about 20KW

(5) Quick-change filter screen devices can reduce the crystallization point of plastic film surface, to improve the quality of film surface

(6). Air ring   PE  330 mm

(7) Air ring, die head air-cooled motor: 7.5KW     efficient frequency control of electricity, high precision double vents air ring, rainbow-chip device can further improve the output.

(8) It's largest plasticizing capacity  140 kg/h

Suitable raw materials: LDPE, LLDPE, HDPE, EVA, MLLDPE, etc.

(9).Max reduced diameter of film  1400mm

3, Tractor     BQ1600

Tower-type rack, rotating traction, horizontal position back and forth 360 degrees progressiverotation, and devided into upper , middle and lower-layer, rack is devided into four tiers from the ground to the top, and the bottom and the middle layer use 150 * 150 * 4 square iron, the total hight is 9m.

(1) Guide roller diameter:  100 mm, with static balance

(2) AC motor traction with traction

Traction motor power: 1.5KW

(3) Rolling aluminum alloy running roller collapser.

(4) Frame diameter of foam stability to the adjustment, flexible and convenient, blown film stability, the under shaking, and the effect of stabilize bubble is good.

(5) EPS ultrasonic rectification system, contactless detection, good anti-interference ability, long-term work stability, with memory function

Pulling speed: 6-60m/min

(6) Collapser use rolling aluminum alloy running roller collapser, few film scratches, to improve film surface optical ploperty to make film tidy.

(7) Traction machine using horizontal swing rotation, rotation steady, rotation speed stepless adjustable. To overcome the problems of different size of two side of the film roller, elastic sides etc, to ensure a good film flatness. Air cushion guide steel roller and film flattening roller spin orientation, to make film tidy.

4, Winder      BJ1600

Use double winding type, with wind shaft replaced the gas expanded shaft, film rewinding diameter  850 mm

(1) Under traction use torque motor to automatic follow the plastic film on-line tension

Torque Motor Model: YLJ100-8    Stall Torque  60 kg/cm

(2) Winding motor use AC motor to control the speed, and combine with the traction motor, so that plastic film can maintain a stable tension

(3) Winding with AC motor machine

(4) automatic winding

Power: 1.5KW controller use Taida controler to control the electricity, so that the tension of plastic film tension stable and can be adjusted.

(5) a set of lengthways straddle cutting confiquration, a set of edge cutting device, a set of rectification device.

5, Control system

The original device main use the Japanese high quality brand products, digital temperature controller RKC Instrument

Pressure use high-temperature melt pressure sensor digital intelligent instrument display.

6, Thickness uniformity of plastic film products: thickness tolerance ≤ ± 8%
