BL-6178-B Program-controlled laboratory blown film machine
Introduction: The program-controlled laboratory blown film extruder blown film means that the plastic melt is continuously extruded through the die under a certain temperature and a certain shearing force, and is inflated by compressed air, air ring cooling and frequency conversion traction. The process of obtaining a bi-fold plastic film. This machine is mainly used to detect the blown film feasibility of polymer materials and the gel condition in the material, as well as the dispersion of colored dispersion, control mixture and extrudate. Technical Parameters: Screw diameter: Ø20 Aspect ratio: 1: 28 Screw speed: 0-95rpm frequency control Screw material: 38CrMoAlA chrome-molybdenum alloy, the surface is treated by quenching, nitriding, chrome plating, polishing and super-fine grinding. The roughness Ra≤0.4μm, the depth of the nitride layer is ≥0.6mm, the hardness is HRC55～60. Barrel material: 38CrMoAlA chrome-molybdenum alloy, the surface is treated by quenching, nitriding, chrome plating, polishing and super-fine grinding, roughness Ra≤0.4μm, nitride layer depth ≥0.6mm, hardness HRC55～60 Heating zone: Mica heater in zone 3, heater in zone 2, copper fins in each zone, stainless steel safety hood Cooling zone: 3 sets of multi-wing fan super static forced air cooling Drive motor: precision geared motor Electronic control system: PLC programmable color touch screen, human-machine interface operating system, extrusion process can be dynamically displayed and monitored, including temperature control, drive, pressure, interlocking joint control function Power supply: 3∮, AC380V, 50Hz three-phase five-wire Volume: 1350×500×940 (W×D×H)mm (without adjustable electric control box) Weight: about 235kg Blowing tower Mold diameter: Ø30 Inflatable gas: compressed air 0~6bar adjustable Cooling gas: blast flow rate 30L/min Traction roller: Ø80×L320mm Winding roller: Ø80×L320mm Maximum diameter of film: 150mm Traction motor: 90W Winding: Friction winding Fan: 0.25KW Observation box: 10W LED light source Electronic control system: PLC programmable color touch screen, human-machine interface operating system, extrusion process can be dynamically displayed and monitored, including temperature control, drive, pressure, interlocking joint control function Volume: 820X700X2050 (W×D×H) mm Power: 3∮, AC380V, 15A Weight: about 205kg
