Fig. 2 is side view of the present utility model.
Specific embodiment
In order that technological means, creation characteristic, reached purpose that the utility model is realized more understand and are easy to effect
Understand, the utility model is further elaborated with reference to the accompanying drawings and detailed description：
As a kind of preferred embodiment of the present utility model, also referring to accompanying drawing 1 and Fig. 2：
The utility model provides a kind of production of plastic optical fiber and uses auxiliary material extruder, including frame 2, machine barrel 3, hopper 5, pushes away
Enter screw rod 4, motor 14, deceleration device 1 and attemperating unit 8, the machine barrel 3 is the tubular structure of internal run-through and has position
In the charging aperture on barrel and the discharging opening positioned at cylinder wherein one end, the hopper 5 is connected with the charging aperture, the machine barrel
3 are horizontally fixed in frame 2, and the augering screw 4 is placed in the machine barrel 3, and the motor 14 is arranged on the another of machine barrel 3
One end, and be connected with the augering screw 4 by the deceleration device 1；Wherein, the attemperating unit 8 is connected to machine barrel 3
Discharging opening, and the three-level heater including being sequentially connected in series, in hollow body being included per one-level heater and being arranged on
Electric heater 7 on empty body, set-up mode of the electric heater 7 on hollow body enables to shape inside hollow body
Into the adjustable electrical heating space of temperature, wherein one end is connected to discharging after the hollow body of the heater at different levels connects successively
Mouthful, the other end constitutes auxiliary material extrusion.
In the embodiment above, the attemperating unit 8 is made up of three-level heater, and every grade of heater can be adjusted independently
The temperature of auxiliary material, has three-level heating process successively equivalent to the direction being pushed into according to auxiliary material in section machine barrel 3；When in use,
Auxiliary material enters in machine barrel 3 from hopper 5, by after the promotion of the augering screw 4 driven by motor 14, auxiliary material enters temperature control
The hollow space of device 8, and by being expressed into the discharge end of machine barrel 3 into mould by lead-screw 4 after three-level heating and carrying out
Shaping.A kind of mode of heating for preferably being melted to auxiliary material is that the heating and temperature control of third level heater is cladding
Required optimum temperature, the heating-up temperature of second level heater is more slightly lower than the heating-up temperature of third level heater, reduces
Scope is 2 DEG C -8 DEG C, and the heating-up temperature of first order heater is more slightly higher than the heating-up temperature of third level heater, improves scope
It is 2 DEG C -8 DEG C.Its principle is, by after first order heating devices heat, auxiliary material was in molten condition, makees in the propulsion of screw rod
Under, melting charge is fully interior to be mixed into the heater of the second level, is dropped by the temperature of second level heater so that melting
Expect that internal temperature is more uniform, enter back into third level heater will melt chat temperature lifting to the required temperature of actual cladding
Degree, cladding optical fiber smooth in appearance out is uniform, without raised and depression.
Further, on the basis of such scheme, in the three-level heater in heater described in every one-level
Cooling fan 6 is also equipped with empty body.The effect for installing blower fan is that blower fan and heater coordinate the fast velocity modulation that can realize temperature
Section, after temperature increases to over desired value, can start blower fan and be lowered the temperature；Or heater and radiation air are open simultaneously
Machine, makes temperature more easily control.
Further, on the basis of such scheme, the electric heater 7 is the electrical heating being coiled on hollow body
Pipe.Can cause that the heating of electric heater 7 is more uniform by the electric heating tube for winding, be carried out to machine from the surrounding of electric heater 7
Cylinder 2 is heated, and temperature is increased more uniform.
Further, on the basis of such scheme, the deceleration device 1 is gear reduction box, and the motor 14 passes through
Driving belt 12 is connected with the gear reduction box, and in Fig. 2,11 is belt pulley.Because reduction box 1 is conducted heat by machine barrel,
Reduction box can generate heat, and motor 14 is after driving belt 11 and reduction box 1 are connected so that heat can not be transferred to drive
On dynamic motor, play a part of to protect motor.
Further, on the basis of such scheme, the driving belt 12 is V belt.V belt is in this practicality
Transmission effect in new is not in the phenomenon of belt slippage preferably.
