A kind of automatically upper material blending device
The utility model relates to plastic greenhouse film production equipment field, relates in particular to the upper material blending device in a kind of canopy film production.
In the prior art, the spice in the production process of canopy film and material loading are by manually completing, and its shortcoming is: 1, spice is inhomogeneous, affects product quality; 2, poor stability, threatens operator's personal safety; 3, material loading and spice speed are slow, there will be the situation that stops production because of fracture; 4, operator's labour intensity is high, and production efficiency is low.
Utility model content
For the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of automatically upper material blending device, is used for completing material loading and spice operation in plastic greenhouse film is produced.
The utility model adopts the basic conception of technical scheme to be: in the funnel-form spice bucket that columniform feeding tube is connected with its top, screw rod is housed, in the part of this screw rod in feeding tube, be provided with in helical blade, part in spice bucket and be provided with screw, and driven by belt pulley by motor, below described feeding tube, be provided with loading hopper, described spice bucket is connected to the board hopper being arranged on extruder by tremie pipe.
As further improvement, the return duct arranged side by side with described feeding tube is also housed between described spice bucket and loading hopper.
The beneficial effects of the utility model are, by manually reinforced to loading hopper at lower, material is first arrived spice bucket by spiral in feeding tube pipe, pass through propeller agitation at spice bucket again, then be transported to board hopper by tremie pipe, thereby complete material loading and spice work, reduced so greatly hand labor amount, improved production efficiency; And spice is even, guarantee the quality of product; Material loading and mixing speed are fast, there will not be and cause stopping the situations such as production as the fracture of other material-uploading style; Handling safety, convenience.

The specific embodiment
As shown in drawings, in the funnel-form spice bucket 2 that columniform feeding tube 1 is connected with its top, screw rod 3 is housed, in the part of screw rod 3 in feeding tube 1, be provided with in helical blade 4, part in spice bucket 2 and be provided with screw 5, and driven by belt pulley 7 by motor 8, described feeding tube 1 is provided with loading hopper 6 below, and spice bucket 2 is connected to the board hopper 10 being arranged on extruder 11 by tremie pipe 9.Various raw materials are introduced into loading hopper 6 by preset proportion, and rise to spice bucket 2 by the helical blade 4 in feeding tube 1, described various raw material is stirred by screw 5 in spice bucket 2, after mixing, under the control of blowing baffle plate 12, deliver to board hopper 10 by tremie pipe 9, thus complete material pour, promote, stir, enter process into.The return duct 14 arranged side by side with feeding tube 1 is also housed between spice bucket 2 and loading hopper 6, its effect has two: one, because helical blade 4 and screw 5 are synchronous interactions, material is back to loading hopper 6 through return duct 14 by spice bucket 2, thereby material is circulated between loading hopper 6 and spice bucket 2, make mixing of materials more fully more even; Its two, can reclaim the material in spice bucket 2 by return duct 14.Reverse flow baffle 13 is for controlling opening and turn-offing of return duct 14.
