Double conical twin screw extruder making machine manufacturer with SIEMENS PLC

The conical twin-screw plastic extruder can directly process polyethylene (PVC) powder into various plastic products such as pipes, plates, profiles, sheets, etc. It can also be used for polyvinyl chloride powder granulation.

Structure for Conical twin screw extruder :/twin screw extruder
1.1 This machine is composed of AC motor, gear reduction box, distribution gear box, quantitative feeding device, spring feeding, extrusion system, exhaust system, cooling and temperature regulation system, electrical control and other parts.
1.2 The electric motor transmits the power to the gear reducer to reduce speed through the plum blossom flexible coupling, and then the distribution gear box distributes the power to the two screws to obtain a speed of 3.87-38.7 rpm to adapt to various extrusion conditions. need.
1.3 The power transmission system is made of high-quality alloy steel after heat treatment and finishing, with good mechanical properties and sufficient load-bearing capacity.
1.4 The barrel and the distribution gear box are connected by trapezoidal threads. After the repair or adjustment is completed, the two screws are aligned with the spline sleeve of the distribution box and the barrel can be locked by turning the large nut.
1.5 Before disassembling the barrel, raise the collar connecting the feeding barrel and the feeding sleeve, turn the feeding barrel to a certain angle, and then turn the barrel out.
1.6 The upper part of the barrel is equipped with an exhaust system, and the exhaust seat is equipped with a vacuum gauge and a pressure regulating valve, which can adjust the vacuum degree of the system at any time. The vacuum degree of the vacuum pump is not more than 0.85Mpa. The vacuum system is composed of a water ring vacuum pump and a vacuum tank. The lower part of the vacuum tank is equipped with a water drain valve to drain the accumulated water.
1.7 Note: During the working process of the vacuum pump, the vacuum pump should be turned on to prevent damage to the vacuum pump.
