Abstract
The utility model relates to a combined threaded rod used for parallel twin screw extruders. A mandrel is sheathed with a plurality of thread sleeves of different outside diameters, different kinds of thread height and different numbers of thread heads, wherein the thread sleeves are fixedly connected into a whole to form the combined threaded rod with changeable heads, diameters and depth. Any two of the three kinds of thread sleeves are combined and connected to the mandrel or the three kinds of thread sleeves are simultaneously combined and connected to the mandrel. The utility model can meet the requirement of low temperature extrusion and improve the blending effect of materials and has the outstanding advantage for reducing color difference at the time of processing color masterbatch products and the general utility function of enhancing mixing and extrusion, and provides the machine with multiple functions.
Description
The utility model relates to the used combined threaded rod of a kind of parallel double-screw extruder.
The used parallel double-screw combination of domestic existing parallel double-screw extruder is taked isometrical usually, Deng dark constant combining form, and the output of the screw rod groove depth of parallel parallel dual-screw and product is closely related, the variation of screw head number is relevant with material dispersed and blend effect, it is straight that the diameter of screw rod and the variation of pitch can be adjusted the speed of service and the running status of material in machine barrel, connect the quality that influences the blend of parallel dual-screw effect and extruded product, the general domestic existing isometrical grade that adopts is dark, constant screw combinations, the bad dispersibility that has mixing extruded material, extrude and yield poorly and the blending and modifying function such as is limited at shortcoming, effect is relatively poor when low temperature is extruded especially.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of parallel double-screw extruder that had not only had good dispersion but also can satisfy the output high request to deepen combined threaded rod with a change reducing.
Technical solution of the present utility model:
A kind of parallel double-screw extruder deepens combined threaded rod with becoming a reducing, it includes mandrel, it is characterized in that on mandrel, being set with a plurality of external diameter differences, depth of thread difference and the different thread bush of number of starts, they are fixed with one and constitute become a reducing and deepen combined threaded rod, any two are connected above-mentioned three kinds of dissimilar thread bush on mandrel, or three kinds are connected on mandrel simultaneously.
The utility model adopts three in screw combinations, the multiple thread cover that waits of two head threads mixes assembling with the kneading piece, change the screw diameter and the depth of thread simultaneously and multiple transition element reconfigures, form one or more and become head, reducing, the novel combined threaded rod that deepens, be complementary with the reducing of extruder barrel, use in parallel double-screw extruder by the screw rod that reconfigures, make combined threaded rod tight at first but afterwards loose, adjust operating machine internal pressure, screw rod is when running up, because it is big that the volume of extruding zone becomes, it acts on similar axial screw pump, improves and extrudes output.New reducing, displacement, bull, deepen screw combinations, can satisfy low temperature extrudes, improve material blend effect, improve the quality of products, it is outstanding to reduce the aberration advantage during especially to processing Masterbatch product, simultaneously reducing, displacement, deepen, become the utilization of a screw combinations in the parallel double-screw mixing extruder, can improve the mixing general utility functions of extruding, for a tractor serves several purposes provides advantageous conditions.
Fig. 1 is a structural representation of the present utility model.
As Fig. 1, the utility model includes mandrel 1, characteristics of the present utility model are to be set with the different thread bush 2 of a plurality of external diameter differences, depth of thread difference and number of starts on mandrel 1, they are fixed with one and constitute become a reducing and deepen combined threaded rod, but any two are connected above-mentioned three kinds of dissimilar thread bush 2 on mandrel 1, or three kinds are connected simultaneously on mandrel 1.
In the utility model, the pitch of each thread bush 2 on the mandrel 1 can be identical, also can be different, and this requirement difference according to processing materials is selected.
The assembled arrangement of each thread bush 2 is selected according to the needs of material to be machined, can be reducing and deepen thread bush 2 and mix permutation and combination on mandrel 1, also become head and deepen or reducing and change head thread cover 2 mix permutation and combination on mandrel 1, also become head, deepen, reducing mixes permutation and combination simultaneously on mandrel, forms the combined threaded rod of difference in functionality.Each thread bush 2 can adopt spline structure and mandrel 1 to be fixed with one.
Operation principle of the present utility model such as Fig. 1, Fig. 1 be reducing in the combined threaded rod, deepen, become head and displacement one section, and each thread bush 2 can directly fit together, and also can mix assembling with the kneading piece as required.After combined threaded rod of the present utility model is placed on the parallel double-screw extruder, it is at one section thread bush 2-1 that adopts three shallow slot screw threads of reinforced place beginning, in order to carry and strong mixing compression, become two transition thread bush 2-2 by three then, become the thread bush 2-3 of two deep trouth screw threads, make the utility model screw diameter become big, groove also deepens, make volume-variation, play the axial screw pumping action.Then adopt transition thread bush 2-4 again, two is become the thread bush 2-5 of three shallow slots, material is strengthened disperse, improve melting effect.And, make volume become big by three thread bush 2-6 that become two deep trouth screw thread, and not only play the axial screw effect, also help exhaust, extrude thereby reach low-temperature material.
