Abstract
The utility model discloses a non-stop screen changer for a polypropylene waste extruder by using a backup way. The non-stop screen changer comprises two extruders which are mounted in parallel and are independently communicated with a forming mould through a filtering device and a filtering screen, wherein a backflow control valve is mounted between the filtering device and the forming mould. The two extruders are mounted in parallel and are independently communicated with the forming mould, so that only one extruder works during the normal production. When the filtering screen is completely blocked and needs to be replaced, the other extruder is started up; the extruder with the filtering screen needed to be replaced is shut off when material can be supplied as normal; and then the filtering screen can be replaced. The non-stop screen changer for the polypropylene waste extruder by using the backup way, disclosed by the utility model, has the advantages of not only improving quality stability of products, but also obviously reducing time waste and material consumption, saving time, saving consumption and guaranteeing quality as the non-stop screen changer can continuously filter and supply material during the screen replacement process. The non-stop screen changer for the polypropylene waste extruder by using the backup way can realize non-stop production.
Description
Technical field
The utility model relates to the Polywoven Bag production equipment, and promptly a kind of backup method polypropylene waste material extruder is not shut down net-changing device.
Background technology
At present; Common Polywoven Bag production process is following: raw material → plastic-wire drawing machine → winder → circular weaving machine → compounding machine → printing machine → cutting bag machine is put a bag frame → sack closer → baling press → dispatch from the factory; Have a large amount of waste materials to produce in the production, many impurity is arranged in the waste material of recovery, the waste material of recovery is through broken, oven dry; The raw material that oven dry is good is put wire drawing machine into and is re-used, and drops into and produces.Get into extruder after under the mutual shearing of the external heat of 190-250 ° of C and screw rod and machine barrel at raw material; Material is under almost completely plasticizing situation; Extruded through mould molding by quantitative, level pressure; The film that becomes molten gets in the cooling water, after cooling, gets into wire-drawing equipment and finally forms flat filament.In order to prevent that impurities in raw materials particle etc. from getting into mould, before the plasticizing back gets into mould fully, screen pack is housed at raw material.But; Screen pack is designed to fixed structure usually in existing molding machine equipment; Changed again when screen pack stops up the charging machinery that must stop under the out of use situation fully, therefore influenced ordinary production, wasted plenty of time and plastic raw materials.
Summary of the invention
In order to overcome the deficiency of existing molding machine the problems referred to above, the utility model provides a kind of new design that method polypropylene waste material extruder is not shut down net-changing device of backing up.
This backup method polypropylene waste material extruder is not shut down net-changing device; Comprise two extruders, it is characterized in that two extruders is in parallel installed with; And, between filter and mould, be equipped with recycle control valve alone through filter and screen pack and mould connection.
The employing two extruders is in parallel installed with, and connects with mould alone, has only an extruder job during ordinary production.When the complete blocked needs of filter screen are changed, just start another extruder, treat and just to turn off the extruder that needs are changed filter screen during normal feed, change filter screen then.
The beneficial effect of the utility model is that the draping process is uninterruptedly filtered, feed, can not only improve the stability of quality of item, can also significantly reduce the loss of waste of time and material, the effect that play when saving, joint consumes, guarantees the quality.Can realize not shutting down production.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the scheme schematic diagram of the utility model.
Among the figure: 1. filter, 2. screen pack, 3. mould, 4. extruder, 5. recycle control valve.
The specific embodiment
This backup method polypropylene waste material extruder is not shut down net-changing device; Comprise two extruders 4; Two extruders 4 is in parallel installed with, and connects through filter 1 and screen pack 2 and mould 3 alone, between filter 1 and mould 3, is equipped with recycle control valve 5.
