1. single screw extruder
Axial thrust using ZLYJ series of professional single-screw rubber extruder supporting the design of high precision hardened thrust seat belt gear box, front-end configuration of the output shaft thrust bearing to withstand the screw at work, the whole small size, carrying capacity, smooth transmission, low noise, high efficiency;
the sheet die: hanger die with two throttle design, sheet thickness accurately. Temperature control ± 1 ºC can accurately control the plasticizing process and sheet thickness, flatness. The material effective width 2150mm; product width 2100mm; Thickness 3-8mm, die material: 5CrNiMoV steel, a total of 11 district heating, the use of stainless steel heating rods; Dies hard chrome plated surface.
3. three-roll calender:
Double tube spiral blade circuit so that the roller surface temperature uniformity, L / cooling quickly and without a lot of cooling medium. Roller surface hardening, grinding, hard chrome plating (coating thickness not less than 0.10mm) after mirror polished, hardness HRC62 above, the roller surface runout is less than 0.02mm, the surface temperature error within ± 2 ºC. HTM attached swivel joints and heat resistant pressure hose.
Wheel positioning: using precision screw lift its components, the central wheel fixed to the upper and lower motor Coarse wheel gap, manual fine-tuning can be adjusted independently around. The purpose can be achieved quickly adjust the gap and precision trimming simultaneously. The mechanism of high strength, high precision, the optimized design is to ensure the quality of the finished sheet core components.
4. traction equipment: traction trimming cooling device
Shears maximum width: 2000mm maximum thickness:. 4mm, shear rate, 20 beats / min.
6. the conveyor belt:
Part3. the wide range of applications:
The production line can produce eva shoes, PE, PP or PVC sheet material such as sheet metal, high calcium carbonate added (up to 50-75); strong ability to adapt equipment, can be processed simultaneously PP, PE, ABS, PS and so on.
Application: car roof, car trunk mat, car mats and so on;
Qingdao Leader Machinery Co.,ltd has been devoted to study the new extrusion technology of plastic sheet. Our PP PE PS HIPS and Polycarbonate, PMMA,PET, EVA etc sheet machine has been exported to USA, Europe and Korea etc countries. Welcome your inquiry for more communication.
