Description

A kind of plastic wood mixing extruder

Technical field:

The utility model relates to the extruder technology field, is a kind of plastic wood mixing extruder specifically.

Background technology:

Extruder is the universal machine of plastics industry, be used for goods such as the various plastic tubes of extrusion molding, polybag, plastic grain and plastic sheet, general plastic extruder can only use single material, operation principle is that plastic processing is become a kind of melt, increase pressure and temperature and make its even plasticizing, carry out moulding by various moulds again, shortcoming is the material of different performance below two kinds can not to be mixed mutually, and especially the object that heating can not be able to not be flowed mixes mutually; In order to address the above problem, someone has invented a kind of pulsation exhaust plastic wood mixing extruder, its patent No. is: ZL200520118247x, plastics that can fusion and string (as wood powder, peanut shell etc.) that can not fusion can be blended together mutually and be a kind of novel material, but thisly mould wooden extruder and in use be prone to the two-flight screw fracture that adds end material, it changes frequent, production efficiency is low, and two-flight screw all to be changed at every turn, the cost height can't be realized large-scale industrial production.

Summary of the invention:

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of plastic wood mixing extruder is provided, and mainly solves existing two-flight screw easy fracture, problems such as replacing is frequent, production efficiency is low, cost height of moulding wooden extruder.

In order to achieve the above object, the utility model is achieved in that a kind of plastic wood mixing extruder, it comprises extrudes body and barrel, barrel one end with extrude body and be connected, the other end is established discharging opening and fervent head, on near the barrel of extruding the body end, establish loading hopper and steam vent, in barrel, establish screw rod, screw rod in the barrel of loading hopper and steam vent below is a two-flight screw, in the barrel in two-flight screw downstream is milling device, establish adjustable pin on the barrel of milling device correspondence, in the barrel in milling device downstream is single-wormed screw, its special character is that described two-flight screw is made up of three parts, first's two-flight screw, connect by key between second portion two-flight screw and the third part two-flight screw three, the barrel of three part two-flight screw correspondences is split, is fixed together between the three part barrels, the barrel partial fixing of second portion two-flight screw correspondence can be dismantled and be changed on the barrel of both sides.

A kind of plastic wood mixing extruder of the present utility model, its described two-flight screw is tapered, and its depth of thread progressively reduces to the downstream from the upstream.

A kind of plastic wood mixing extruder of the present utility model, its described steam vent is three rows, and every row is 4-8 hole, and three rounds evenly distribute on the circumference of barrel.

A kind of plastic wood mixing extruder of the present utility model, its described adjustable pin are 8-16.

A kind of plastic wood mixing extruder described in the utility model is compared with civilian industry technology has following good effect: 1, raw material uses waste and old plastics and broken string, but the material recycled for multiple times of making, because of not using glue in process, string is not to use plastic bonding together, so this material non-toxic is tasteless, environmental protection, cost is low; 2, equipment volume is little, feeding is fast, be uniformly dispersed, mixing of materials is permeated, the two-flight screw partial design of main is equipment is three parts, and the most serious position of wearing and tearing is detachably changed, and is easy to operate, reduce the input of equipment loss, the maintenance fund of having saved equipment.

Description of drawings:

Fig. 1 is a barrel part-structure schematic diagram of the present utility model;

Fig. 2 is a screw portion structural representation of the present utility model;

Fig. 3 is a screw portion structural representation of the present utility model.

The specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe a kind of plastic wood mixing extruder of the utility model in detail.

Embodiment 1, referring to Fig. 1, be processed into and extrude body and barrel 1, barrel 1 one ends with extrude body and be connected, the other end has discharging opening 5 and fervent head 6, loading hopper 2 is installed and is offered steam vent 3 near the barrel 1 of extruding the body end, and steam vent 3 is three rows, every row is 4-8 hole, and three rounds evenly distribute on the circumference of barrel 1; Screw rod 4 is installed in barrel 1, screw rod 4 comprises two-flight screw 7 and single-wormed screw 10, screw rod 4 in the barrel 1 of loading hopper 2 and steam vent 3 belows is a two-flight screw 7, two-flight screw 7 is tapered, and its depth of thread progressively reduces to the downstream from the upstream, two-flight screw 7 is made up of three parts, first's two-flight screw 11, connect by key 14 respectively between second portion two-flight screw 12 and the third part two-flight screw 13, the barrel of three part two-flight screw correspondences is three parts of split, be fixed together by flange between the three part barrels, the barrel partial fixing of second portion two-flight screw 12 correspondences can be dismantled and be changed on the barrel of both sides; In the barrel 1 in two-flight screw 7 downstreams is milling device 8, and adjustable pin 9 is arranged on the barrel 1 of milling device 8 correspondences, and adjustable pin 9 is 8-16, is single-wormed screw 10 in the barrel 1 in milling device 8 downstreams.
