Ttb135d double station hollow stretch blow molding machine consists of frame, extruder, storage die head, closing mechanism, blowing device, manipulator, cooling device, safety protection device, electrical control system, hydraulic control system and pneumatic control system. It is mainly suitable for processing various hollow products with PE, PP, ABS and other raw materials.
1. Extrusion system
(1) Extruder requires high production efficiency, good plasticization quality, uniform mixing color, uniform color of hollow products, and the internal quality and appearance quality of the products can meet the requirements of commercial inspection.
(2) Suitable for processing powder, granular, recycled material, color masterbatch mixture.
(3) It has wide adaptability to raw materials.
(4) The proportion of recycled materials is wide.
(1) Screw diameter: 135mm.
(2) Aspect ratio: 27:1. Screw material of zlyj330 gearbox (3): high quality nitriding steel is selected, surface nitriding treatment is adopted, the nitriding layer thickness is 0.4mm, and the hardness HV ≥ 900.
(4) Material barrel: 38crmoaia of high quality nitriding steel is selected. The internal surface is nitrided, and the hardness is HV ≥900。
(5) Driving mode: AC motor is selected, frequency conversion is used to adjust speed automatically, and the winch is kept in normal production without stopping, and the motor is connected with gearbox belt.
(6) Driving power: 132kw
(7) Screw speed: 0-50r/min low speed high efficiency screw.
(8) Temperature control: adopt automatic temperature control module, can realize PID precision control.
(9) heating mode: adopt cast aluminum and mica heating ring or ceramic and mica heating ring.
(10) cooling mode: air cooling
(11) Hopper base: circulating water cooling, cooling water flow can control.
(12) plasticizing capacity: about 400kg/h HDPE.
(13) Heating power of barrel: 52kw.
2. Die head system
Features: continuous extrusion part is electroplated and polished.
(1) The die head runner structure is designed by advanced plastic melt flow analysis software abroad. The core runner and the middle ring have no dead angle. After the melt is combined in the die head, it enters the material storage cylinder. The formed material embryo has good strength and fast color change.
(2) the servo cylinder and injection cylinder have large area, Ensure that injection force and servo force meet the processing needs of high viscosity high molecular weight and high density polyethylene during the forming of material embryo.
(3) 38crmo is used for main parts of runner and mouth mold
(4) The new sealing structure is adopted for the cylinder seal, which ensures good sealing and long service life.
(5) Mica heating ring is used for die head heating ring. The special structure design is adopted to ensure that the heating ring and die head are tightly attached, with high heat transfer efficiency and long service life.
(6) The wall thickness control technology can effectively control the weight of the product and improve the performance of the product.
(1) Die head model: 120L maximum die diameter 350mm
(2) Heating power of die head: 8kw
(3) Heating mode: cast aluminum and mica heating ring or ceramic and mica heating ring are used
(4) Temperature control: temperature control module
(5) Die size: provided by customer (or by sample)
(6) Total hydraulic power: 30KW
(7) Average energy consumption of the double station hollow blow molding machine: 50kw/h
