Background technology
Injection machine is a kind ofly material can be manufactured to the forming machine of given shape, is widely used in the fields such as chemical industry, petrochemical industry, pharmacy, food, building materials, mining and metallurgy, environmental protection, printing and dyeing, pottery, rubber, plastics.
Carrying out at present cable insulation injection moulding is mainly to adopt single screw injection molding machine and the incorgruous two kinds of injection-moulding devices of double-screw injection molding machine for the production of cable insulation of taper.But because single screw injection molding machine output is very low, energy consumption is also larger, therefore mostly adopt at present the incorgruous double-screw injection molding machine for the production of cable insulation of taper to carry out the injection moulding of cable insulation.Owing to being subject to processing the impact of technique, the effective L D ratio of the incorgruous double-screw injection molding machine screw rod for the production of cable insulation of taper has been subject to certain impact, so affected the soffening of raw material, simultaneously due to the current incorgruous double-screw injection molding machine screw rod counter rotating for the production of cable insulation of taper, so caused the rotating speed of screw rod can not be too high, otherwise can cause screw rod to be twisted off, therefore, reduce the output of unit interval, increased the energy consumption of unit interval.
Utility model content
For solving the problems of the technologies described above, we have proposed, and a kind of extrusion capacity is large, energy consumption is low, good, the simple to operate double-screw injection molding machine for the production of cable insulation of plasticizing mixing behavior.
For achieving the above object, the technical solution of the utility model is as follows:
For the production of a double-screw injection molding machine for cable insulation, by drive motors, hopper, feeding mechanism, machine barrel, heating arrangements, conical screw, mould, water cooling tank, drier and the granulating mechanism be located in frame, formed; Described hopper is located on described feeding mechanism; Described heating arrangements and two conical screws are located in machine barrel; Described drive motors drives described feeding mechanism; Described machine barrel connects described feeding mechanism; Described mould connects described machine barrel; Described water cooling tank is installed near described mould; Described drier is installed near described water cooling tank; Described granulating mechanism is installed near described drier; Described two conical screw rotating Vortexes.
Preferably, described drive motors is by driving reduction box to drive described feeding mechanism.
Preferably, described drier is air blast.
Preferably, described heating arrangements is electric heating coil.
Pass through technique scheme, the utility model is by being located at described heating arrangements and two conical screws in machine barrel, the same-directional high-speed rotation in machine barrel of described two conical screws, make to have advantages of large to material extrusion capacity, energy consumption is low, plasticizing mixing behavior is good, simple to operate.
