Abstract
The utility model discloses a novel hot feeding extruder, which comprises a screw rod (3) and a reducer (5), and is characterized in that the screw rod (3) is connected with the reducer (5) through a spline (6), and the ratio between the length and the diameter of the working threaded part of the screw rod (3) is more than 4.5, and the thread is designed to have identical depth and different distances. The spline (6) is of an involute spline (6). The thread guiding distance is gradually increased from the working thread part to the conveying section of the screw rod (3), and the thread guiding distance at the extruding sections is identical and is smaller than that of the conveying section. The novel hot feeding extruder has the advantages of convenient maintenance and replacement, good air tightness of the extruded product, high quality grade, high feeding efficiency and high yield.
Description
Technical field
The utility model relates to rubber and plastics machine equipment, especially a kind of novel hot-feed extruder.
Background technology
At present, the hot-feed extruder technical characterstic on the market is:
The connecting mode of screw rod is generally: the radial bearing of studdle and the radial bearing that bears screw axial thrust are installed in the afterbody of screw rod, and the hollow output shaft of screw rod and decelerator connects with singly-bound; Other extruders then are the output shaft prolongations with decelerator, and output shaft is exposed at the outer part machining screw of reduction box outward becomes screw rod, and promptly screw rod and output shaft are an integral body.The screw rod dismounting difficulty of these structures, maintenance or replacing are all inconvenient.
The length of the screw flight part of hot-feed extruder and the ratio (draw ratio) of screw diameter are 4.5, and draw ratio is smaller, so extrusion pressure is not high enough, the poor air-tightness of extruded product, and credit rating is low.
The screw thread simplicity of design of screw flight part is to wait dark equidistant helicitic texture, cause feeding efficient not high, yield poorly, compression ratio is little, quality of item is poor.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and provides a kind of screw rod maintenance, replacing conveniently, and the extruded product air-tightness is good, credit rating is high, feeding efficient height, the novel hot-feed extruder that output is high.
The utility model is realized by following method:
A kind of novel hot-feed extruder comprises screw rod and decelerator, and different is: screw rod connects with decelerator by spline, and the length of screw rod working thread part and the ratio of diameter are greater than 4.5, and its screw thread is arranged to wait not equidistant deeply.
Described spline is an involute spline.
The feeding part lead of working thread on described screw rod part is to the descending gradual change of transportation section lead, and the extruding zone lead equates and less than the transportation section lead.
Owing to adopt said structure, screw rod and decelerator pass through splined, maintenance, easy accessibility; The draw ratio of screw rod is greater than 4.5, and extrusion pressure is bigger, has improved the air-tightness of extruded product, Products Quality grade height; The design of new-type screw thread has improved the output of extruder, with existing extruder mutually specific energy improve more than 30%, feeding efficient is greatly improved, the output height, simultaneously, sizing material is compressed in the course of conveying of screw rod, has improved the goods air-tightness.

The specific embodiment
Below in conjunction with drawings and Examples the utility model content is further elaborated.
Embodiment:
With reference to Fig. 1, a kind of novel hot-feed extruder comprises head 1, machine barrel 2, screw rod 3, support 4, motor, shaft coupling and decelerator 5, and screw rod 3 connects with decelerator 5 by spline 6.
Spline 6 adopts involute spline.
The length of screw rod 3 working threads part is 690mm, and diameter is 115mm, and the ratio of length and diameter is 6, and its screw thread is arranged to wait not equidistant deeply.
The feeding part lead of working thread on the screw rod 3 part is to the descending gradual change of transportation section lead, and the extruding zone lead equates and less than the transportation section lead.Wherein,
1, the feeding part lead is 100mm, single helical pitch;
2, transportation section lead: forward part helical pitch lead is 100mm, single helical pitch, and the rear section lead is 100mm, two helical pitches;
3, the extruding zone lead is 100mm, two helical pitches.
