Abstract
The utility model discloses an online cast film rim charge recovery device, which comprises a waste material discharge pipeline communicated with an extruder, and a new material discharge pipeline adjacent to the waste material discharge pipeline, as well as a box body, wherein the upper side of the box body is communicated with a waste material conveying pipeline, the waste material discharge pipeline is arranged inside the box body, a conveying screw for conveying powder is arranged in the waste material discharge pipeline, an expanded opening is formed in the upper end of a discharge pipeline, a baffle plate is arranged on the upper end of the opening, and an air nozzle is formed in one side of the discharge pipeline. A waste material in the box body is injected into the discharge pipeline with the expanded opening through the air nozzle, the waste material entering the discharge pipeline basically is uniform small particular waste material as the small-particle waste material more easily floats upward, the uniformity of the waste material in the conveying screw can be guaranteed, and the stability of the extruded waste material can be guaranteed.
Description
Technical field
The utility model 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 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 casting films rim charge online 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: a kind of 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.
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, guarantee 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 guaranteed to enter in discharge pipe is the old material of uniform granule substantially, guaranteed old material in conveying screw rod evenly, guaranteed to extrude the stable of old material.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of traditional structure.
Fig. 2 is the utility model structural representation.
The specific embodiment
Below the utility model is described in further detail, referring to Fig. 2, a kind of casting films rim charge online recycling 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, 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 discharge pipe 2 upper ends have the opening of expansion, in this open upper end, baffle plate 3 is set, be provided with air nozzle 5 in described discharge pipe 2 one sides.
Described old material conveying tube road 7 is connected with described casing by a cyclone separator 40, 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, guarantee old material carry 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, by opening air nozzle 5, air nozzle 5 sprays air old material is kicked up, and strikes the opening that falls into 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.After mixing, the virgin material of old material after carrying by conveying screw rod 8 and in virgin material discharge pipe 4 enter extruder.And the air nozzle 5 by a side on discharge pipe 2 is concentrated air-out, therefore old material is not easy to go out to stop up at the sidewall of baffle plate 3 and discharge pipe 2.
Claims (2)
1. a casting films rim charge online recycling 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), it is characterized in that: comprise casing (1), 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 described old material discharge pipe (2), be provided with the conveying screw rod (8) for delivery of powder, described discharge pipe (2) upper end has the opening of expansion, in this open upper end, baffle plate (3) is set, be provided with air nozzle (5) in described discharge pipe (2) one sides.
2. a kind of casting films rim charge online recycling device as claimed in claim 1, is characterized in that: described old material conveying tube road (7) is connected with described casing by a cyclone separator (40).
