Abstract
The plastics industry is the emerging industry, is in a modern industry important profession, compares it with other industries is young, but prospects for development broad Industry sector.
In the machine-building industry, the plastic widespread is used for to make the components, the part. Statistics indicated that probably has 25 plastics to use in mechanical and electrical profession each department every year. Plastic machinery gets up with but step-by-step growing up of development of industry.
In the plastic machinery, the plastic extruding machine is one of most aircraft types, is the plastic products process load biggest one kind of processing machinery. Plastic forces out machine having broad application in modern industry, phi120 plastic extruders among them are used for various thermoplastic plastics’ mainly to force out molding. If deploying the corresponding hand piece and auxiliary engine , selecting and using the right bolt , being able to Geon (soft or hard) plastic continuation such as polyethylene , polypropylene , ABS be pushed against manufacture the tube , film , bottle , belt , silk , granule , board , heterotypic products such as material , wire cable. Its main characteristic is: The characteristic, electricity absorbing the advanced abroad product of the same kind charges a box for being composed of the integration form with forcing out machine. Design bolt having various forms, long footpath ratio is big. Adopt the silicon controlled rectifier continuous current dynamo drive, steeples speed regulating is stable reliable, frequency conversion electric motor also available. Machine is set up outside the tube casting the aluminum heater, and be qualified for have a cooling to use a blower. From digital display temperature under the control of instrument realization, the automation charges the temperature, fixes the temperature. Have axial force overload protection and the moment of torsion overload protection function. Adopt the intellectualized two digitized obvious temperature to charge an instrument, realizes auto control, under the control of accuracy height. The design designing entire allocation, drive including those phi120 plastic forces out machine this time systematically, bolt axle bearing part structure and their design arranging a form, squeezing system, main part school examines.
