Description
Technical field
The present invention relates to tubing field, and in particular to a kind of modified plastic extruder.
Background technology
Plastic extruder is used for the plasticizing and shaping for completing plastics.Raw material heating is made solid feed become uniform by extruder
Viscous fluid, and in the presence of the pressing mechanism of extruder, make fused materials with certain pressure and speed continuously from
Head extrusion, as required plastic.The pressing mechanism of extruder includes screw rod, barrel, is connected to barrel one end and is used for
The hopper that is fed into barrel, it is connected to the head of barrel the other end, the mould on head.Screw rod and barrel
Coordinate, realize to the crushing of plastics, softening, melting, plasticizing, exhaust and compacting, and sizing material continuous uniform is delivered to head and squeeze
Go out.Extruder also includes the transmission mechanism of drive screw turns, melts plastic raw materials and be generally arranged at the heating on barrel
Mechanism, barrel, screw rod and hopper etc. are cooled down with control temperature ensure plastics be in technological requirement within the temperature range of
Cooling body.
The heater of used plastic extruder is typically all by some pieces of heating plates and power supply group in the prior art
Into heating plate is separately mounted to cylinder body bottom, heating plate and power electric connection, power-on, and heating plate generates heat after being powered, so
Heating plate heated cylinder body bottom, and material is constantly extruded screw rod rotary squeezing in cylinder, and material is pressed against cylinder body bottom
When can be heated thawing, can thus have a problem that, although material can all be extruded to cylinder body bottom, in cylinder body bottom quilt
Heating and melting, but so also can be uneven in the presence of heating, the problem of heating effect is poor, this has ultimately resulted in the push of plastics and squeezed
Go out not smooth enough.Therefore, it is necessary to propose a kind of new technical scheme to solve these problems.
The content of the invention
The present invention proposes a kind of modified plastic extruder, and solution prior art heating is uneven, and heating effect is poor to ask
Topic.
To achieve these goals, the technical proposal of the invention is realized in this way：A kind of modified plastic extruder, bag
Include base, hollow metal cylinder, feed bin, extrusion screw rod, motor and thermatron, the two ends of the metal cylinder with
The base is fixedly linked, and the feed bin is vertical on the base, and the metal cylinder is interconnected with the feed bin, institute
The one end for stating extrusion screw rod is located in the metal cylinder, and the other end of the extrusion screw rod is stretched into the feed bin, the electricity
The output shaft of machine and the extrusion screw rod are rotated by driving belt and be connecteds, the thermatron include high frequency coil with
Power supply, the high frequency coil is wrapped circumferentially around on the periphery wall of the metal cylinder, and the high frequency coil has two electrodes,
Two electrode respectively with the power electric connection.
It is preferred that, the high frequency coil is formed by some circles of body bending.
It is preferred that, the cross section profile of the body is rounded.
It is preferred that, the cross section profile of the body is rectangular.
Compared with prior art, present invention tool has the advantage that：
In modified plastic extruder proposed by the present invention, thermatron includes high frequency coil and power supply, high week
Swash circle is wrapped circumferentially around on the periphery wall of metal cylinder, and high frequency coil has two electrodes, and two electrodes are electrically connected with power supply respectively
Connect.So after high frequency coil is electrified, the positive and negative molecule in magnetic field, cylinder is generated between the electrode of coil two in magnetic field
High-speed motion, friction generates heat, promotes the material in cylinder to melt, because high frequency coil is wrapped circumferentially around metal cylinder
On periphery wall, cylinder can be heated uniformly everywhere, and the material in cylinder just can be heated uniformly, and change is passed through height
The electric frequency of cycle coil can just adjust the temperature of heating, and firing rate is fast, and heating effect is good.Therefore, compared to existing skill
Art, the present invention has homogeneous heating, the good advantage of heating effect.
