Fig. 2 waits to plastify right state.
Fig. 3 waits to plastify left state.
Concrete embodiment
The present invention is further described below in conjunction with drawings and Examples.
The external diameter of intermediate cylinder 4 equates that with the internal diameter in material chamber 1 internal diameter of intermediate cylinder 4 equates with the path of plasticizing roller 5, so that sealing.
The path of plasticizing roller 5 and the end face of barrel 1 internal diameter and intermediate cylinder 4 constitute an annular housing.
The bigger diameter end face of plasticizing roller 5 and barrel 1 internal diameter and nozzle 2 constitute a cylindricality cavity.
The internal diameter in large diameter-ratio material chamber 1 of plasticizing roller 5 is little, so that constitute a little annular gap that is used to plastify, occurrence can require decide according to plasticizing, and the annular gap is little then to plastify shear action greatly but the Flow of Goods and Materials resistance is big.There is oblique chamfering on the both sides in plasticizing roller 5 big footpaths, so that material enters above-mentioned narrow annular channel.
The outer ring in material chamber 1 is equipped with the annular heating collar of not drawing among Fig. 1.
Entire work process is as follows:
The loading hopper 14 of material from Fig. 1 adds, intermediate cylinder 4 moves back and forth backward, to push material chamber 1 from the material that loading hopper 14 adds, reaching intermediate cylinder 4 after the required feeding quantity moves to position shown in Figure 1 and stops to the direction of front shoe 3, to close charge door, intermediate cylinder 4 and material chamber 1 have constituted an airtight cavity simultaneously
Plasticizing roller 5 moves to rear fixed plate 7 directions while rotating by given rotating speed and translational speed, material melts under the heat effect of spin friction heat that plastifies roller 5 and heater, simultaneously, because plasticizing roller 5 moves to rear fixed plate 7 directions, the material that melts flows through plasticizing roller 5 big footpaths and the narrow slit that material chamber 1 constitutes under pressure, produces strong rotational shear plasticizing.When plasticizing roller 5 moves to when colliding with intermediate cylinder 4, material has been replaced the cylindricality cavity by annular housing.Then, plasticizing roller 5 oppositely moves, and also promptly moves towards the direction of front shoe 3, and the material reverse flow is crossed the narrow slit that plasticizing roller 5 big footpaths and material chamber 1 constitute, and produces strong rotational shear plasticizing once more, gets back to annular housing up to material by the displacement of cylindricality cavity.This moment, material can not flow out from nozzle 2 because the plasticizing back pressure is relatively lower.If the plasticizing back pressure is than higher, then nozzle 2 can adopt valve type nozzle.Said process can circulate repeatedly by given number of times, the plasticizing of controllable rotation speed system and the mixability of rotation.The speed-controllable system plasticizing back pressure and the fusion time that move.To adapt to the different requirements of different material to plasticizing rate.
The plasticizing circulation finishes always at Fig. 2 state.
After plasticizing finished, intermediate cylinder 4 moved at side and promotes plasticizing roller 5 under the dynamic action and move towards the direction of front shoe 3 simultaneously, and material can flow out from nozzle 2 under the high pressure effect.At this moment, reinforced, the plasticizing of one-period, discharging process are all over.Intermediate cylinder 4 and plasticizing roller 5 are reset to Fig. 1 state together, plastify next time.
Above-mentioned discharging process cooperates injection molding can realize injection, cooperates extrusion die can realize extruding.
In the above-mentioned plasticizing circulation, also can be reinforced more midway, to realize prescription or controllable reaction plasticizing midway.
But also ring installation on the external diameter of intermediate cylinder 4 is to increase sealing.
The layout of whole device can be horizontal, also can be vertical.
If whole device be arranged as vertical upwards, also can in material chamber 1, directly feed in raw material by unloading nozzle 2; If being arranged as of whole device is vertical downward, also can be by unloading nozzle 2 and utilizing the pyramidal pits of nozzle 2 to feed in raw material.
