Abstract
The present invention discloses a conical bidirectional twin-screw extruder. It is formed from drive motor, coupler, speed-reducing distribution box, feeding system, machine cylinder, conical twin-screw, exhausting system, granule-cutting system and feeding funnel, et.
Description
Technical field
The present invention discloses that a kind of being applicable to of using extruded, the granulation conical parallel dual-screw extruding machine in plastics or rubber processing.
Background technology
As everyone knows, the extruder of using in plastics or rubber processing at present has parallel parallel dual-screw extruding machine, parallel counter rotation twin screw extruder and taper counter rotation twin screw extruder; The advantage of parallel parallel dual-screw extruding machine is that plasticizing capacity is good, its shortcoming be extrude that power is little, deceleration distributor box complex structure and power consumption be big; And parallel counter rotation twin screw extruder is at plasticizing capacity and extrude on the power all not good; And the advantage of taper counter rotation twin screw extruder is that to extrude power big, and shortcoming is that plasticizing capacity is poor, thereby all unsatisfactory in actual the use, it seems that plasticizing capacity has become a pair of contradiction with the power of extruding in extruder.We know, plasticizing capacity is poor, will directly have influence on the quality of plasticizing back product, can and the power of extruding has influence on output and cost, design a kind of extruder for this reason, collects above-mentioned advantage, and go its shortcoming, break through the defective of present extruder, the working ability of updating the equipment, seeming has crucial economic worth and application value.
Summary of the invention
For overcoming the deficiency of above-mentioned technology, extruder provided by the present invention had both had good plasticizing capacity, had again simultaneously well to extrude power.
The present invention is made up of members such as drive motors, shaft coupling, deceleration distributor box, feed system, machine barrel, screw rod, pelletizing system, hoppers.The above-mentioned technology of the present invention is finished by conical double-screw and joining distributor box, and conical double-screw makes conical double-screw keep same direction (referring to equidirectional or equidirectional counterclockwise clockwise) when rotated by the deceleration distributor box; The helix of the conical double-screw of equidirectional rotation is equidirectional rotation.
The equidirectional rotation of above-described conical double-screw is to finish by three gears being arranged in the deceleration distributor box; Driving gear connects main cone shape screw rod and is meshed with idler gear, and idler gear is meshed with driven gear again, driven gear auxiliary connection conical screw, thus make major and minor conical screw reach rotation in the same way.
The present invention---conical parallel dual-screw extruding machine, the equidirectional rotation of its conical screw makes the plastics of processing after entering machine barrel, processed plastics become the extruding of 8 fonts around the biconial screw rod in machine barrel, fusion time and banburying performance have been increased, thereby guaranteed the plasticizing quality of product, kept the good plasticizing capacity of parallel dual-screw extruding machine; Because the screw rod that adopts is taper, so the screw rod end in the deceleration distributor box has enough spaces, can select the thrust bearing of big specification for the present invention for use, can bear the power of extruding greatly of conical screw, kept the good power of the extruding performance of conical double screw extruder, it is compared with above-mentioned existing extruder, has the following advantages, promptly have the premium properties of existing extruder concurrently: extruding that power is big, output improves, energy consumption reduces, is the novel extruder that is fit to various plastics and rubber processing.

Accompanying drawing 3: screw rod of the present invention cross sectional representation in barrel
Accompanying drawing 4: screw-rod structure schematic diagram of the present invention
Specific embodiments
Structure of the present invention sees shown in the accompanying drawing 1, and it is by drive motors 1, shaft coupling 2, deceleration distributor box 3, feed system 4, machine barrel 5, conical double-screw 6, gas extraction system 7 is extruded pelletizing system 8, hopper 9 and frame 10 are formed, design feature of the present invention is that screw rod 6 is made up of two conical screw 6-1 and 6-2, and conical screw 6-1 is a driving screw, and 6-2 is a sub-screw, see shown in the accompanying drawing 4 that they are seen shown in the accompanying drawing 3 in the position in machine barrel 5; In deceleration distributor box 3, arrange three angular wheels, see shown in the accompanying drawing 2 that drive motors 1 is connected with driving gear 11 by shaft coupling 2, driving gear 11 is meshed with idler gear 12, and idler gear 12 is meshed with driven gear 13; Driving gear 11 is connected with main cone shape screw rod 6-1, and driven gear 13 is connected with secondary conical screw 6-2.When driving gear 11 rotates, drive idler gear 12, idler gear 12 drives driven gear 13 makes master and slave gear do to rotate in the same way, thereby makes major and minor screw rod do equidirectional rotation with the rotation of master and slave gear; The helix of conical double-screw also is equidirectional rotation.Therefore the present invention is by the cooperation of conical double-screw and three angular wheels, make conical double-screw reach rotation in the same way, what both kept conical double-screw extrudes thrust greatly, the plasticizing capacity that has kept parallel parallel dual-screw has again overcome the shortcoming that above two kinds of existing extruder thrusts are little and plasticizing is poor.Improved output, saved energy consumption, have extrude, the good function and the economy of granulation, be the novel extruder that is fit to various plastics and rubber processing, have and use and popularizing action.
