Abstract
The invention discloses casting films leftover material 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, also comprise casing, be communicated with old material conveying tube road at described casing upside, described 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, in the porch of described old material discharge pipe, gear cap is set, casing below arranges base, described base comprises the ventilative board being connected with described casing lower end and the cavity arranging below ventilative board, described cavity is connected with a compressed gas source. the present invention is ejected into the old material in casing in discharge pipe by ventilative board, because short grained old material is more prone to float to upper strata, therefore the old material that has ensured to enter 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 leftover material 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 leftover material recycling device, realize determining of powderAmount is carried, and has realized the stable of extrusion capacity.
The present invention is achieved through the following technical solutions: casting films leftover material recycling device, comprises be communicated with extruder oldMaterial discharge pipe and the virgin material discharge pipe adjacent with described old material discharge pipe, also comprise casing, is communicated with at described casing upsideOld material conveying tube road, described old material discharge pipe is arranged at described box house, in described old material discharge pipe, be provided with forThe conveying screw rod of carrying powder, arranges gear cap in the porch of described old material discharge pipe, and casing below arranges base, the described endSeat comprises the ventilative board being connected with described casing lower end and the cavity arranging below ventilative board, and described cavity and a compressed gas source connectConnect.
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 is ejected into the old material in casing in discharge pipe by ventilative board,Because short grained old material is more prone to float to upper strata, therefore ensure to enter old material in discharge pipe substantially for uniformly littleParticle old material, ensured old material in conveying screw rod evenly, ensured to extrude the stable 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, casting films leftover material recycling device, comprises with extruder and connectingLogical old material discharge pipe 2 and the virgin material discharge pipe 4 adjacent with described old material discharge pipe 2, also comprise casing 1, in instituteState casing 1 upside and be communicated with old material conveying tube road 7, described old material discharge pipe 2 is arranged at described casing 1 inside, described oldIn material discharge pipe 2, be provided with the conveying screw rod 8 for delivery of powder, in the porch of described old material discharge pipe 2, gear be setCap 3, described casing 1 below arranges base 5, and described base 5 comprises the ventilative board 50 that is connected with described casing lower end and thoroughlyThe cavity 51 that aerofoil 50 belows arrange, described cavity 51 is connected with a compressed gas source, and ventilative board 50 has for compressed air logicalThe small pore of crossing, and old material cannot pass through this pore.
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,Compressed gas source starts, and compressed air is kicked up the old material in casing 1 by ventilative board, and old material falls into discharging after striking gear cap 3In the opening of pipeline 2 upper ends, because tiny particle is easily kicked up, the old material particle that therefore drops into discharge nozzle porch is largeLittle substantially close, therefore the old material in conveying screw rod 8 is more even. Old material goes out at and virgin material rear by conveying screw rod 8 conveyingsAfter mixing, virgin material in pipe material 4 enters extruder.
