Abstract
The utility model discloses a cast film recycling device, comprising a box body, wherein a waste material conveying pipeline is communicated with the upper side of the box body; a waste material discharge pipeline is arranged inside the box body; a conveying screw rod for conveying powder is arranged inside the waste material discharge pipeline; an expanded opening is formed in the waste material discharge pipeline; a protective cover is arranged outside the waste material discharge pipeline; an opening is formed in the protective cover; a base is arranged below the box body; a cavity is formed in the base and connected with a compressed air source; an air nozzle communicated with the cavity is arranged on one side of the waste material discharge pipeline inside the protective cover. The waste material in the box body is jet to the discharge pipeline with the expanded opening through the nozzle; as waste materials with small size easily float to the upper layer, the waste materials, with small even size, entering the discharge pipeline can be ensured, the waste materials in the conveying screw rod are even, and stable extrusion of the waste materials is ensured.
Description
Technical field
The utility model 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 after extruder hopper and virgin material mix and is entered extruder again by blower fan.This hopper is double-decker, skin is virgin material, and internal layer is powder, and the powder that blower fan is carried enters internal layer hopper by cyclone separator, because powder is low weight, therefore in the middle of internal layer hopper, there is a compacting screw that powder 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 is the powder delivering pipe after fragmentation, and 4 be cyclone separator, 5 discharge pipes that are cyclone separator, and 6 internal layers that are hopper, storage powder, 7 is hopper skin.
The defect that this device exists is in the time that rim charge width changes, the powder that is transported to hopper also can change, the bulk density that compacting screw is extruded into the powder of extruder charging aperture also can change, cause the thickness of film unstable, and in the time that powder is too much, 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 utility model provides a kind of casting films leftover material recycling device, has realized the quantitative conveying of powder, has realized the stable of extrusion capacity.
The utility model is achieved by the following technical solution: casting films retracting 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, described old material discharge pipe has the opening of expansion, be outside equipped with guard shield at described old material discharge pipe, described guard shield arranges opening, described casing below arranges base, on described base, cavity is set, described cavity is connected with a compressed gas source, in described guard shield, be positioned at described old material discharge pipe one side and be provided with the valve being communicated with described cavity.
In technique scheme, described old material conveying tube road is connected with described casing by a cyclone separator.By described cyclone separator, the powder passing in casing is carried out to initial gross separation, to filter the larger waste material of larger particles and corner wherein, ensure old material carry waste material in funnel evenly.
The utlity model has following beneficial effect: the old material that the utility model clings in casing by nozzle is ejected in the discharge pipe with enlarged openings, 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.
Brief description of the drawings
Fig. 1 is the schematic diagram of traditional structure.
Fig. 2 is the utility model structural representation.
Fig. 3 is the structural representation of guard shield.
Detailed description of the invention
Below the utility model is described in further detail, referring to Fig. 2 to Fig. 3, casting films retracting device, comprise the old material discharge pipe 2 that is communicated with extruder and the virgin material discharge pipe 4 adjacent with described old material discharge pipe 2, also comprise casing 1, be communicated with old material conveying tube road 7 at described casing 1 upside, described old material discharge pipe 2 is arranged at described casing 1 inside, in described old material discharge pipe 2, be provided with the conveying screw rod 8 for delivery of powder, described old material discharge pipe 2 has the opening of expansion, be outside equipped with guard shield 3 at described old material discharge pipe 2, described guard shield 3 arranges opening 30, described casing 1 below arranges base 5, on described base 5, cavity 51 is set, described cavity 51 is connected with a compressed gas source, in described guard shield 3, be positioned at described old material discharge pipe 2 one sides and be provided with the valve being communicated with described cavity 51.The interior refrigerating plant 6 that arranges of described cavity 51, described old material discharge pipe 2 is by described cavity 51.
Described old material conveying tube road 7 is connected with described casing by a cyclone separator 70, by described cyclone separator 40, the powder passing in casing is carried out to initial gross separation, to filter the larger waste material of larger particles and corner wherein, ensure old material carry waste material in funnel evenly.After falling, old material enters into guard shield 3 by the opening 30 of guard shield 3 interior near near valve 9, the air-flow spraying by the valve 9 old material of kicking up, guard shield 3 arranges in opening 30 upper ends the baffle plate 31 bending inwards, form with the opening in old material conveying tube road 2 passage passing through for old material, due to the setting of guard shield 3, old material need to prevent that a large amount of old material are blocked in the passage that old material passes through by kicking up by entering valve 9 after opening 30 again.
When use, by described old material conveying tube road 2, the leftover pieces (being old material) after pulverizing are conveyed into described casing 1, compressed gas source starts, compressed air is kicked up the old material in casing 1 by valve, old material strikes the opening that falls into discharge pipe 2 upper ends after guard shield 3, because tiny particle is easily kicked up, the old material granular size that therefore drops into discharge nozzle porch is substantially close, and therefore the old material in conveying screw rod 8 is more even.After mixing, the virgin material of old material after carrying by conveying screw rod 8 and in virgin material discharge pipe 4 enter extruder.
In described cavity 51, insert a refrigerating plant 6, compressed air is lowered the temperature after refrigerating plant 6, discharge by valve 9, in the old material of kicking up, old material is lowered the temperature, reduce old material frictional heating in conveying screw rod 8, the danger of the thermal decomposition in course of conveying is less, and described old material discharge pipe 2 is by described cavity 51 inside, refrigerating plant 6 can be lowered the temperature to the discharge pipe 2 in cavity 2 simultaneously, more reduced the danger of old material thermal decomposition in conveying screw rod 8.
