Description
Technical field
The utility model relates to a kind of plastics recovery treatment facility, is specifically related to a kind of integral type flexible flake material forced-feeding device of single screw extrusion machine.
Background technology
In waste plastics recovery process, usually need to carry out pressure group (granulation) process to the plastic flakes reclaimed, make recycled plastic turn agglomerate granular, be convenient to follow-up recycling.Pressure group (granulation) technique is completed by single screw extrusion machine usually, during work, recycled plastic is fed to the spout of single screw extrusion machine, by the forwardtransfer signal worm in single screw extrusion machine by recycled plastic driven forward, in propelling movement process, shearing heating is carried out to recycled plastic, if desired in conjunction with outside electric-heating-wire-heating, make recycled plastic melting, the back segment of described forwardtransfer signal worm is arranged to pitch decrescence structure, thus after recycled plastic melting, it is extruded, finally go out to extrude at the extrusion die of extruder end, the group's of being formed strip, or formed granular through pelletizing.
Recycled plastic is being carried out in pressure group (granulation) processing procedure, when handling object is flexible sheets material (such as plastic sheeting, disposable cup, disposable lunch box, nylon cloth etc.), due to these materials have quality light, soft, fluffy, easily wave, even occur the characteristics such as material " bridge formation ", therefore not easily entering into forwardtransfer signal worm when carrying out feeding, causing feeding difficulty.In order to solve this problem, mainly have employed two technological means: 1, forced-feeding device is set on a single-screw extruder in prior art, forced to send in forwardtransfer signal worm by flexible sheets material by this forced-feeding device, this forced-feeding device mainly contains reciprocating forced-feeding device and screw-pushing type forced-feeding device etc.; 2, by independently rolling into a ball pressure device, flexible sheets material is pressed into a bar (grain) shape, then is sent in the spout of single screw extrusion machine.
There is the deficiency such as inefficiency, complex structure in above-mentioned 1st kind of technological means, such as, for reciprocating forced-feeding device, its work poor continuity, causes mass transport efficiency low; For screw-pushing type forced-feeding device, although can realize continus convergence, the conveying capacity in the unit interval is few, causes transfer efficiency low.In above-mentioned 2nd technological means have that processing step is many, complicated operation, the artificial and high deficiency of equipment cost.
In addition, the extruder drawing-in device adopting double-screw structure to carry out forced feed is also there is in prior art, this drawing-in device utilizes the screw rod of extruder itself and additional screw rod to form double-helical screw mechanism, rotate backward by controlling twin-screw during work, thus form charge motion in the intersection of two screw rods, such as publication number is the one " extruder drawing-in device " disclosed in the application for a patent for invention of CN1278207A, and application publication number is " a kind of double-screw feeding device of Rubber Extruder " disclosed in the application for a patent for invention of CN104441561A.Above-mentioned twin-screw forced feed mechanism not only can continuous operation, and rate of feeding is very fast, and operating efficiency is high, stability; But when be applied to forced feed is carried out to flexible sheets material time, due to flexible sheets material have quality light, soft, fluffy, easily wave, even occur the characteristics such as material " bridge formation ", the helicitic texture body rotated during above-mentioned double-screw structure work is difficult to the below these flexible sheets materials being brought into two screw rods, and efficiency, the reliability and stability of feeding are poor.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of integral type flexible sheets material forced-feeding device of single screw extrusion machine is provided, this forced-feeding device adopts double-screw structure, be applied to and forced feed is carried out to flexible sheets material, there is the advantages such as operating efficiency is high, reliability is high, good stability.
