Connected and installed with flange arrangement between cylinder outlet.
The bare wire material can be conductor wire core or be steel wire rope or be rope or be carbon fiber, optical fiber or be food
Billot.
It is clamped with the flange arrangement and the sieve plate that material is sieved is coated to guide ring intracavitary.
Beneficial effects of the present invention：
1st, the energy saving and environment friendly extrusion coating machine in the same direction of the present invention (is used compared to routine techniques without traditional cladding head
Coating mould takes band cladding head), coating machine head material is saved, cost of manufacture is reduced, adjusting machine time and tune machine is reduced
When the material that is wasted, improve product processing quality, energy-saving, emission-reducing, environment friendly.
2nd, occupied ground of the present invention is small, can arrange that many (sets) extrude coating machine in the same direction in the space of conventional art place.
3rd, the present invention is simple and convenient, and an operative employee can operate 5~6 (sets) to extrude coating machine in the same direction simultaneously, and
In conventional art, an operative employee at most 2 extrusion coating machines of operation simultaneously.
4th, the present invention does not have conventional extruder header structure, eliminates many set die heating elements and its supporting control system,
Easily controllable temperature, it is energy-saving.
5th, the present invention is extruded for concentric type and coated, for relatively conventional angled type extruder, is wrapped during extrusion cladding
Cover thing does not have influence of unbalance power to being wrapped by thing so that product quality is more preferably controlled, and waste product is less.
6th, many playscripts with stage directions invention extrusion coating machine can be stacked up or be at an angle of to place and with hot rifle passage coupled to be formed
Co-extrusion, repeatedly can also be extruded series, parallel.
