Abstract
The invention discloses the retracting device for casting films rim charge, including casing, casing is arranged below base, described base includes the ventilative board being connected with described casing lower end and the cavity being arranged below at described ventilative board, described cavity and a compressed gas source connect, being inserted with a refrigerating plant in described cavity, described old material discharge pipe is by described inside cavity.The present invention is ejected into the old material in casing in discharge pipe by ventilative board, owing to short grained old material is more prone to float to upper strata, thereby ensure that the old material essentially uniform old material of little granule entered in discharge pipe, ensure that the uniform of old material in conveying screw rod, ensure that and extrude stablizing of old material, and the thermal decomposition danger that material is in screw rod reduces.
Description
Technical field
The present invention relates to Rim charge recovery device of cast film.
Background technology
This casting films equipment in process of production, after rim charge can be cut away pulverizing online, enters back into extruder be transported to extruder hopper and virgin material mixing by blower fan after.This hopper is double-decker, and outer layer is virgin material, and internal layer is powder, and the powder of blower fan conveying enters internal layer hopper by cyclone separator, owing to powder is relatively lighter, therefore has a compacting screw that powder is extruded into extruder charging aperture and virgin material mixing in the middle of internal layer hopper.As shown in Figure 1: 1 is extruder, 2 is powder compacting screw, and 3 is the powder delivering pipe after crushing, and 4 is cyclone separator, and 5 is the discharge pipe of cyclone separator, and 6 is the internal layer of hopper, stores powder, and 7 is hopper outer layer.
The existence of this device has the drawback that when rim charge width changes, the powder being transported to hopper also can change, compacting screw is extruded into the bulk density of the powder of extruder charging aperture and also can change, cause that the thickness of thin film is unstable, and when powder is too much, powder also can be put up a bridge at extruder charging aperture and be caused that blanking is not smooth.
Summary of the invention
For the deficiencies in the prior art, present invention provide for the retracting device of casting films rim charge, it is achieved that the quantitative conveying of powder, it is achieved that stablizing of extrusion capacity.
nullThe present invention is achieved through the following technical solutions: for the retracting device of casting films rim charge，Including the old material discharge pipe connected with extruder and the virgin material discharge pipe adjacent with described old material discharge pipe，Also include casing，Old material conveying tube road is connected on the upside of described casing，Described old material discharge pipe is arranged at described box house，It is provided with the conveying screw rod for carrying powder in described old material discharge pipe，Described conveying screw rod includes diminishing first of the flight pitch being sequentially connected with、Second and diminishing 3rd of the flight pitch that flight pitch expands gradually，In the porch of described old material discharge pipe, gear cap is set，Casing is arranged below base，Described base includes the ventilative board being connected with described casing lower end and the cavity being arranged below at described ventilative board，Described cavity and a compressed gas source connect，A refrigerating plant it is inserted with in described cavity，Described old material discharge pipe is by described inside cavity.
In technique scheme, described old material conveying tube road is connected with described casing by a cyclone separator.Initial gross separation is carried out, to filter the bigger waste material of larger particles therein and corner, it is ensured that in old material conveying funnel, waste material is uniform by the described cyclone separator powder to passing in casing.
Be there is advantages that the present invention is ejected in discharge pipe by ventilative board the old material in casing, owing to short grained old material is more prone to float to upper strata, thereby ensure that the old material essentially uniform old material of little granule entered in discharge pipe, ensure that the uniform of old material in conveying screw rod, it is ensured that extrude stablizing of old material.

Fig. 1 is the schematic diagram of traditional structure.
Fig. 2 is present configuration schematic diagram.
Fig. 3 is the structural representation of conveying screw rod.
Detailed description of the invention
Below the present invention is described in further detail, referring to Fig. 2, retracting device for casting films rim charge, including the old material discharge pipe 2 connected with extruder and the virgin material discharge pipe 4 adjacent with described old material discharge pipe 2, also include casing 1, old material conveying tube road 7 is connected on the upside of described casing 1, it is internal that described old material discharge pipe 2 is arranged at described casing 1, the conveying screw rod 8 for carrying powder it is provided with in described old material discharge pipe 2, described conveying screw rod 8 includes diminishing first 80 of the flight pitch being sequentially connected with, second 81 and diminishing 3rd 82 of the flight pitch that flight pitch expands gradually, first screw feeder place flight pitch is maximum, old material is easily accessible thread groove, bearing capacity is big；Old material enters back in second 81 after being sufficiently mixed in diminishing thread groove after being entered by first again and disperses, and again mixes gradually again, entered the operation of dispersion mixing, it is ensured that old material can be sufficiently mixed uniformly in second 81 after dispersion in the 3rd 82.Preferably, hand of spiral in the 3rd 82 and the hand of spiral in second 81 are contrary, are further ensured that mixed effect.
Gear cap 3 is set in the porch of described old material discharge pipe 2, gear cap 3 has the catch extended to both sides, for increasing the area collided with old material, ensure have enough material to fall in conveying screw rod, described casing 1 is arranged below base 5, and described base 5 includes the ventilative board 50 being connected with described casing lower end and the cavity 51 being arranged below at ventilative board 50, described cavity 51 and a compressed gas source and connects, ventilative board 50 has the Minute pores passed through for compression air, 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, initial gross separation is carried out by the described cyclone separator 40 powder to passing in casing, to filter the bigger waste material of larger particles therein and corner, it is ensured that in old material conveying funnel, waste material is uniform.
During use, leftover pieces (i.e. old material) after being pulverized by 7, described old material conveying tube road are conveyed into described casing 1, compressed gas source starts, compression air is kicked up the old material in casing 1 by ventilative board, old material falls in the opening of discharge pipe 2 upper end after striking gear cap 3, owing to tiny granule is easily kicked up, the old material granular size therefore dropping into discharge nozzle porch is substantially close, and therefore the old material in conveying screw rod 8 is more uniform.Old material virgin material after being carried by conveying screw rod 8 and in virgin material discharge pipe 4 enters extruder after mixing.
Described cavity 51 inserts a refrigerating plant 6, compression air is lowered the temperature after refrigerating plant 6, discharged by ventilative board 50, while old material of kicking up, old material is lowered the temperature, reducing 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 internal by described cavity 51, discharge pipe 2 in cavity 2 can be lowered the temperature by refrigerating plant 6 simultaneously, more reduce the danger that old material thermally decomposes in conveying screw rod 8.
