Abstract

The utility model relates to a single extruding shaper for waste plastics. Through a spiral feeder which is additionally loaded in a hopper, a feeding section screw rod in a machine body is designed to be a taper screw thread structure of a big screw groove, and a flaky waste plastic raw material which is a plurality of times lighter than a granule material can directly enter the shaper which can produce all kinds of needed shaping materials not through recovery and pulverization. The electric power and the manpower are saved, the cost of regenerating the waste plastic into a product is lowered, and the work efficiency is enhanced.

Description

The useless extrusion shaping machine of moulding a time

The utility model belongs to a kind of plastic shaping processing mechanical apparatus.

The existing useless extrusion shaping machine of moulding is a kind of plant equipment for utilizing a large amount of waste or used plastics things generally to use again, and this equipment mainly is made of feed hopper, body, support, screw rod, head, mouth mould and motor.But, therefore, when work, can only carry out extrusion molding processing to graininess or powdered plastic raw material because the core component screw flight and the spiral groove depth of this equipment are uniform Design.That is to say that mould goods for any giving up, all must will give up to mould with the recovery machine earlier be recycled into piece; after disintegrating machine, pelleter are broken into particulate material, can drop into extrusion shaping machine raw product more again, this useless process that secondary is produced raw product again of moulding; the power consumption of consumption power, efficient is lower.Especially to existing waste and old laminar plastics, as the waste plastics woven bag, useless plastic sheeting for farm use, useless food bag or the like because of it is very light and soft, differ bigger with particulate material proportion, and existing equipment is directly feeding and moulding all.

The purpose of this utility model is to provide a kind of can mould the especially laminar useless useless extrusion shaping machine of moulding a time of the direct extrusion molding of raw material of moulding with giving up.

The main technical schemes that the utility model adopts is existing useless moulding on the basis of extrusion shaping machine, in hopper inwall upper fixed pair of bearing, dress bevel-gear sett on it, by bevel gear one screw feeder is installed, the laminar raw material of input hopper is sent in the body under screw press; The feed zone screw rod that is positioned at body is designed to big screw channel taper thread structure, draft and screw rod tapering match in the body, when the screw rod nominal diameter is Φ 90-Φ 150, body inside tapered thread outside diameter then is Φ 180-Φ 300, its screw channel depth capacity is 55-100, and taper thread length is 450-550.This design can laminar uselessly be moulded raw material and press to small end by the big end of screw thread smoothly what enter body, in the pressurized that tentatively is heated, is imported the compression section glibly.

Fig. 1 has provided the structure principle chart of this utility model.

The utility model is described in further detail below in conjunction with accompanying drawing.

In the accompanying drawings, 1 is reducing motor, and 2 is cover, and 3 is bearing, and 4 is bearing holder (housing, cover), and 5 is bearing block, and 6 is the chain transmission, and 7 is bevel-gear sett, and 8 is hopper, and 9 is screw feeder, and 10 is screw rod, and 11 is body, and 12 is machine barrel, and 13 is head, and 14 is a mouthful mould, and 15 is support.The structure of screw rod wherein, change and can be divided into three sections according to material motion and physical state thereon: the part in body is a feed zone, leans in machine barrel into that the part of head is a homogenizing zone, wherein the two mid portion is the compression section.

Body 11 and machine barrel 12 are connected as a single entity with bolt by its upper flange; Screw rod 10 is packed in body 11 and the machine barrel 12, and the one end links to each other with reducing motor 1 by bearing 3, and the other end then links to each other with head 13; Bearing holder (housing, cover) 4 and bearing 3 are put in the body 11, and it is fastening with cover 2, reducing motor drives screw rod 10 rotations, with compression section and the homogenizing zone screw rod of after preliminary pressurized is heated, clamp-oning on the feed zone screw rod of raw material in body 11 in the machine barrel 12, further after pressurized melted by heat and the homogenizing, by head 13 and through fixing the required raw product again of mouth mould 14 (interchangeable as required) output on it.

Hopper 8 usefulness bolts are installed in the charging aperture position of body 11; Hopper 8 inwall upper fixed pair of bearing 5, dress bevel-gear sett 7 on it, by this bevel gear one screw feeder 9 is installed, this screw feeder 9 is driven with screw rod by reducing motor through chain transmission 6 by bevel gear 7 and transports biography synchronously, makes laminar useless raw material enters screw rod under the screw press of screw feeder 9 the feed zone of moulding in the input hopper 8; Feed zone screw rod in the body is big screw channel taper thread structure by dark equidistant and constancy of volume structural design such as the screw channel of continuing to use, and the interior draft of body and this section screw rod tapering match.When the screw rod nominal diameter was Φ 90-Φ 150, its taper thread outside diameter then was Φ 180-Φ 300, and its screw channel depth capacity is 55-100, and this taper thread length is 450-550.

The utility model is compared with existing plastic extruder, owing to installed spiral additional in hopper Feeder has improved feed zone screw rod and housing construction, makes the useless farming than the light several times of particulate material The laminar raw materials such as film, woven bag, food bag do not need can deliver directly this machine of access through reclaiming to pulverize In produce, change different mouthfuls of moulds at head, be equipped with subsidiary engine, can disposablely produce not Goods together, such as plastics malthoid, sheet material, tubing, hollow container has been saved electric power greatly Enter power, reduced the useless cost of moulding again article of manufacture, significantly improved operating efficiency. Adopt this Utility model, but both refuse usefulness have again been administered again environmental pollution, have good economic benefit And social benefit.

Claims

1, the useless extrusion shaping machine of moulding a time, mainly formed by reducing motor, hopper, body, machine barrel, screw rod, bearing, head, mouthful mould and support, hopper is installed in body charging aperture position with bolt, screw rod is contained in body and the machine barrel, the one end links to each other with reducing motor by bearing, the other end links to each other with head, and bearing holder (housing, cover) and bearing are packed in the body, and fastening with cover; The body inner screw partly is called the feed zone screw rod, the machine barrel inner screw partly is divided into compression section and homogenizing zone screw rod, it is characterized in that: fixing pair of bearing on the hopper inwall, dress bevel-gear sett on it, by this bevel gear one screw feeder is installed, the laminar raw material of input hopper is sent in the body under helical pressure; The feed zone screw rod is big screw channel taper thread structure in the body, and draft matches with the screw rod tapering in the body, moulds raw material and presses to small end by the big end of screw thread smoothly in order to entering laminar useless in the body, in the pressurized that tentatively is heated, imports the compression section.
