Putup SJ55X2+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. Specific configuration is as follows: 1, Extrusion machine (three) (1) SJ55 * 2 outer layer extruder Power: 22KW AC-VVVF Inverter brand: Taida Inverter Reducer: 330 type Barrel: groove barrel, feed section use water to cool, 3 districts heating three sections of cold air. Barrel Material: 38CrMoALA Hardness: HRC56-60-62 Screw: Modified Screw L / D ratio: 30/1 Material 38 CrMoALA Hardness HRC56-60 (2) SJ65 * 1 middle extruder Power: 37KW AC-VVVF Inverter brand: Taida Inverter Reducer 370 type Barrel slotted barrel, feed para-pass water-cooled, 3 Districts heating three sections of cold air. Barrel material; 38CrMoALA Hardness HRC56-60-62 Screw modified Screw L / D ratio: 30/1 Material 38 CrMoALA Hardness HRC56-60-62 (3) SJ55 * 1 inner extruder Power 30KW Inverter Control Inverter brand Taida Inverter Reducer 350 type Barrel slotting barrel, feed section use water to cool, 3 Districts heating three sections of cold air. Barrel material 38CrMoALA Hardness HRC56-60 Screw modified Screw L / D ratio 30/1 Material 38 CrMoALA Hardness HRC56-60-62 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% Note send two manual shafts
