PET bottle granule recycling line pellets making machine
Our company new making plastic parallel twin screw extruder machine for plastic PET, PS,fabric,NYLON, and so on
Features
Parallel co-rotating twin screw extrusion system:
The screw and barrel adopt the "building block" structure, which has good interchangeability, and can be used in any combination according to the different material processing technology; the barrel is made of nitrided steel, bimetallic material, wear-resistant,
Corrosion resistance and extended service life; the threaded components are made of nitrided steel and high-speed steel, and the curve is computer-aided design with unique processing technology to ensure the normal teeth of the threaded working section
Surface clearance, and good self-cleaning; the specially designed connection method and transmission device enhance the strength of the threaded element and the mandrel. The above measures achieve uniform material dispersion, good mixing and plasticizing effect, and material stagnation.
The purpose of short residence time and high transmission efficiency.
Deceleration system:
Adopt special gearbox for plastic machinery, [1] The transmission parts are made of high-quality, ultra-high alloy carburized steel, combined with carburizing, quenching, and tooth grinding technology. The key parts have increased surface strengthening treatment, teeth
The surface strength is HRC54-62, the core hardness is HRC30-40, and the gear is level 6. This system has the characteristics of high speed, high torque, and low noise.
Feeding system:
Adopt twin screw with agitator quantitative feeding system, the feeding is uniform and accurate, and there is no phenomenon of racking.
Electronic control system:
Imported electrical components are used, the control panel is a man-machine interface, and each part of the equipment is controlled by "module" (also can be configured according to user requirements). The multi-function module has a clear structure and has safety
Full interlocking device (such as lubrication loss-of-pressure protection, machine head pressure protection, over-current protection, etc.), which truly reflects the running status of the equipment, has accurate control, high sensitivity and convenient operation.
Heating system:
The use of cast aluminum, cast copper, ceramic resistance heating device, uniform heating, rapid temperature rise, high temperature control accuracy.
Temperature Control System:
The dual-channel temperature control meter is adopted, which is sensitive, the temperature setting and adjustment are convenient, and the temperature control accuracy is high.
cooling system:
It adopts two forms of water cooling, oil cooling and air cooling. The cooling is rapid, uniform and effective.
Vacuum system:
Built-in vacuum system, the vacuum degree can reach -0.09Mpa., so as to ensure that the materials are fully plasticized and improve product quality.
Auxiliary machinery:
According to the different process requirements of the user, a variety of pelletizing forms such as cold-stretch pelletizing, drag chain pelletizing, air-cooled die face hot cutting, water ring hot cutting, etc. can be selected.
