Abstract
The invention discloses casting films rim charge online recycling device, comprise the old material discharge pipe that is communicated with extruder and the virgin material discharge pipe adjacent with described old material discharge pipe, comprise casing, be communicated with old material conveying tube road at described casing upside, old material discharge pipe is arranged at described box house, in described old material discharge pipe, be provided with the conveying screw rod for delivery of powder, described discharge pipe upper end has the opening of expansion, in this open upper end, baffle plate is set, is provided with air nozzle in described discharge pipe one side. The present invention is ejected into the old material in casing in the discharge pipe with enlarged openings by nozzle, because short grained old material is more prone to upwards floating, therefore the old material entering in discharge pipe is the old material of uniform granule substantially, ensured old material in conveying screw rod evenly, ensured to extrude the stable of old material.
Description
Technical field
The present invention relates to casting films rim charge online recycling device.
Background technology
In process of production, rim charge can be cut away after pulverizing this casting films equipment online, is transported to extruder material by blower fanBucket and virgin material enter extruder after mixing again. This hopper is double-decker, and skin is virgin material, and internal layer is powder, and blower fan is carriedPowder enter internal layer hopper by cyclone separator, because powder is low weight, therefore have a compacting screw in the middle of internal layer hopperPowder is extruded into extruder charging aperture and virgin material mixing. As shown in Figure 1: 1 is extruder, 2 is powder compacting screw, and 3 arePowder delivering pipe after fragmentation, 4 is cyclone separator, 5 discharge pipes that are cyclone separator, 6 internal layers that are hopper, storePowder, 7 is hopper skin.
The defect that this device exists is in the time that rim charge width changes, and the powder that is transported to hopper also can change, compacting spiral shellThe bulk density that bar is extruded into the powder of extruder charging aperture also can change, and causes the thickness of film unstable, and works as powderToo much time, powder also can be put up a bridge and cause blanking not smooth at extruder charging aperture.
Summary of the invention
For the deficiencies in the prior art, the invention provides casting films rim charge online recycling device, realize powderQuantitative conveying, realized the stable of extrusion capacity.
The present invention is achieved through the following technical solutions: a kind of casting films rim charge online recycling device, comprises and extruderThe old material discharge pipe being communicated with and the virgin material discharge pipe adjacent with described old material discharge pipe, comprise casing, on described casingSide is communicated with old material conveying tube road, and old material discharge pipe is arranged at described box house, in described old material discharge pipe, is provided with useIn the conveying screw rod of carrying powder, described old material discharge pipe upper end has the opening of expansion, in this open upper end, baffle plate is set,Be provided with air nozzle in described old material discharge pipe one side.
In technique scheme, described old material conveying tube road is connected with described casing by a cyclone separator. By describedCyclone separator carries out initial gross separation to the powder passing in casing, to filter the larger waste material of larger particles and corner wherein,Ensure old material carry waste material in funnel evenly.
The present invention has following beneficial effect: the present invention clings to old material in casing by nozzle and is ejected into and has enlarged openingsIn discharge pipe, because short grained old material is more prone to float to upper strata, therefore ensure to enter the old material base in discharge pipeThis be the old material of uniform granule, ensured old material in conveying screw rod evenly, ensured to extrude stablizing of old material.
Brief description of the drawings
Fig. 1 is the schematic diagram of traditional structure.
Fig. 2 is structural representation of the present invention.
Detailed description of the invention
Below the present invention is described in further detail, referring to Fig. 2, a kind of casting films rim charge online recycling device, comprise withThe old material discharge pipe 2 that extruder is communicated with and the virgin material discharge pipe 4 adjacent with described old material discharge pipe 2, also comprise casing1, be communicated with old material conveying tube road 7 at described casing 1 upside, old material discharge pipe 2 is arranged at described casing 1 inside, in instituteState in old material discharge pipe 2 and be provided with the conveying screw rod 8 for delivery of powder, described old material discharge pipe 2 upper ends have expansionOpening, in this open upper end, baffle plate 3 is set, be provided with air nozzle 5 in described old material discharge pipe 2 one sides.
Described old material conveying tube road 7 is connected with described casing by a cyclone separator 70, by described cyclone separator 70The powder passing in casing is carried out to initial gross separation, to filter the larger waste material of larger particles and corner wherein, ensure that old material is defeatedSend waste material in funnel evenly.
When use, by described old material conveying tube road 7, the leftover pieces (being old material) after pulverizing are conveyed into described casing 1,The amount of the accumulation of old material should be no more than position, dotted line place in Fig. 2, and by opening air nozzle 5, air nozzle 5 sprays air and makes oldMaterial is kicked up, and strikes the opening that falls into old material discharge pipe 2 upper ends after baffle plate 3, because tiny particle is easily kicked up,Therefore the old material in conveying screw rod 8 is more even, is mainly the less part of particle in old material. Old material is passing through conveying screw rodAfter mixing, virgin material after 8 conveyings and in virgin material discharge pipe 4 enters extruder. And by a side on discharge pipe 2Air nozzle 5 concentrate air-out, therefore old material is not easy to go out to stop up at the sidewall of baffle plate 3 and old material discharge pipe 2.
