Description
Technical field
The present invention relates to plastic extrusion field, more particularly to a kind of conical parallel dual-screw extruding machine.
Background technology
Being applied to the equipment that plastic conduit and plastic plate manufacture in the market mainly has single screw extrusion machine, taper different
To double screw extruder and conical parallel dual-screw extruding machine.The unique advantage of single screw extrusion machine is exactly that cost is low, but
Extrusion force, plasticizing capacity and energy consumption aspect all existing defects.The advantages of taper counter rotation twin screw extruder is that extrusion force is big, but
That plasticizing capacity is poor, yield poorly, energy consumption it is big.Conical parallel dual-screw extruding machine due to the equidirectional rotation of its conical screw make by
Plastics are processed after machine barrel is entered, is extruded in machine barrel around conical double-screw into 8-shaped, is added fusion time, reduce
The frictional force of plastics and screw barrel, so as to ensure that plasticizing quality, reduce energy consumption；Because the screw rod used for taper, is protected
The good extrusion force performance of conical double-screw comminutor is held.
But conical parallel dual-screw extruding machine often occurs that feeding machine easily blocks in extrusion plastic pipeline and sheet material
Firmly, screw rod shearing heat not enough, plasticizing it is bad cause extruder temperature set be higher by the degrees centigrade of single screw rod 80 could plastify, energy
The higher, product surface of consumption has stomata, product surface to have trichobothrium, has the defects of stomata, product embrittlement inside product, particularly does height
Wretched insufficiency is plastified during filled plastics.In addition, deceleration distributor box system is that the most scabrous design of the double extruders of conical parallel dual is difficult
Topic, because angle is small, space is small, and output gear shaft reference diameter is small, and the number of teeth is few, modulus is done less, and design strength is difficult full
Sufficient load, and three bevel gears can only be used to design in the past, machining accuracy is difficult to ensure card, and intensity further weakens, thus, distribution
Case gear often damages, and design has very big difficulty, there is presently no a good solution, only passes through periodic replacement
Distributor box gear shaft, it is even more exhaust outlet overflow be present when doing plastic conduit, pressure oscillation is big, can not normally produce, machine barrel spiral shell
A series of problems, such as bar dismounting is difficult.

Mouth is corresponding.
As can be seen here, in the present invention, motor 10 imparts power to deceleration distributor box system 20 first, by slowing down
Power is distributed to main conical screw 51 and the secondary taper spiral shell in conical parallel dual-screw system 50 after the speed change of distributor box system 20
Bar 52 so that they obtain consistent steering and material is sent into conical parallel dual-screw by rotating speed, feed system 30 while stirring
In system 50, material successively by feed zone 501, plasticizing zone 502, left-hand thread area 503, secondary plasticizing area 504, Disengagement zone 505,
Exhaust area 506 and extrusion zone 507, when producing plastic plate, plastic pipe or foaming product, accordingly adjust gas extraction system
Corresponding device in 70, so as to complete the preparation of product.In whole preparation process, the transmission moment of torsion of deceleration distributor box system 20
Greatly, bearing capacity doubles, and service life increases substantially and noise is small, in extrusion, conical parallel dual-screw
The shearing heat of system 50 is big, plastifies, is kneaded, filling proportion height, and exhaust outlet not overflow in preparation process, makes
Product strength is good, surface-brightening, can extrusion plastic sheet material and can extrusion plastic tubing.
Although the preferred embodiment of the present invention has been described in detail herein, it is to be understood that the invention is not limited in this
In the concrete structure being described in detail and show, without departing from the spirit and scope of the present invention can be by the technology of this area
Personnel realize other modifications and variant.
