1. The working principle and structural features:
The machine works the same as an ordinary mixer. That mound of material compression pressure in a closed tank through two different ratio of shear rotor rotation, extrusion, mixing, folding rolls after kneading action, plastic (mixed) Make the necessary raw materials.
1.1 Mixing device
Mixing chamber to form a closed tank with left and right side, front and rear rotor bearings with radial spherical roller bearings, fixed to the left and right panels, respectively, through the bearing sleeve.
Left and right side panels are with cooling (heating) chamber jacket structure, the material in contact with the inner wall surface hardening (hard chrome plating) treatment. Mixing chamber wall hard chrome plating thickness 0.1 ~ 0.15mm, hardness HV900 ~ 1000.
The rotor of the long and short two spiral welded edges on the rotor shaft, edge peaks and working parts of the side edge surfaces of the rotor are surfacing wear-resistant carbide seal faces, the hardness of 50HRC, thickness of 5mm. The entire outer surface of the rotor in contact with the material is hardened (hard chromium plating) process, a thickness of 0.1 ~ 0.15mm, hardness of HV900 ~ 1000.
By sealing rotor end gland seal ring against the rotor top seal faces. Sealing ring is made of high temperature, wear-resistant, low coefficient of thermal expansion of bronze and PTFE materials. Work does not end face friction grease lubrication, this will ensure a good seal and not contaminated material.
1.2 Transmission system
The main drive from the main motor via a belt drive, drive reducer, ratio gear reducer output shaft of the drive to achieve relative rotational movement around the rotor through the gear sleeve couplings. Reducer gears and shafts are made within 42 chrome molybdenum material and after nitriding. When unloading host reversed rubber to ensure adequate unloading.
1.3 Flip device and transmission
Flip motor (electromagnetic brake three-phase asynchronous motor) to drive the worm, worm gear reducer by cycloid. Worm gear fixed to the front of the rotor (left bearing housing), the rotation of the worm so that the whole device before mixing rotor axis as the center (forward) to achieve flip discharge. Flip the mixing chamber 140 ° Discharge after recovery position. Flip mixing chamber by a limit switch limit, high precision, good durability.
1.4 Pressing device, dust, and gas control system devices: Driven by the ram cylinder.
The ram pressure device of a "mountain"-shaped mound under pressure to promote the material for cylinder pressure. The ram jacketed welded structure, internal water cooling, the material in contact with the surface hardening treatment. Pressure mound four weeks with sealing strip to prevent leakage of powder mixing process. Pressing device of the top surface of the cylinder is installed in the rack, running from the limit switch limit.
1.5 Heating / cooling system
This machine has a cooling pipe system. Since all parts of the machine are in contact with the jacket material welded structure, the inlet and outlet pipes have a way valve, it is possible to ensure efficient cooling effect.
2. The electrical part of the overview
Omron electrical parts adopt programmable controller as the main controller, the main electrical components using domestic quality products, so that the whole electrical part of the advanced features, simple operation, safe and reliable; According to customer requirements will be the main motor control panel to start, stop, on the top tied up, down, turn back to the mixing chamber, the temperature of the mixing chamber is transferred to the device to operate.
