Technical field
The utility model relates to extruder technology apparatus field, specifically a kind of high-efficiency screw extruder.
Background technology
At present, need in molding powder manufacture that mixed material is entered screw extruder to extrude, general employing double screw extruder, double screw extruder has that fricative heat is less, shearing suffered by material relatively evenly, the conveying capacity of screw rod is comparatively large, extrusion capacity is more stable, material stops the feature grown, mix in machine barrel.But existing screw extruder easily overstocks at the extrusion die place of machine barrel end when Screw Extrusion material, causes express material to have some setbacks.
In order to solve the problem, in prior art, propose following patented technology:
China Patent No. " 201120130461.2 " discloses a kind of screw extruder, and its publication date is on December 21st, 2011.Its technical scheme comprises the machine barrel be located in frame, described machine barrel front end is provided with charge door, and described machine barrel end is extrusion die, is provided with screw rod in described machine barrel, be provided with heater outside described machine barrel, the pitch of described screw rod is increased to extrusion die gradually by charge door.
But with the prior art that above-mentioned patent document is representative, in actual use owing to machine barrel only having an extrusion die, thus can only process the product extruding a kind of shape at every turn, production efficiency is not high, product is also more single, the requirement of production development can not be adapted to, in addition, under the feeding hopper of double screw extruder during fleut, fleut is easily bonded on drawing-in device sidewall, cause " bridge formation " phenomenon, and the bulk materials bondd in powdery, also blanking can be caused obstructed, even blocking can not blanking, affect Pouring oar and the stability of production line.
Summary of the invention
The purpose of this utility model is to provide a kind of high-efficiency screw extruder, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of high-efficiency screw extruder, comprise the machine barrel be located in frame, the front end of described machine barrel is provided with loading hopper, loading hopper comprises cylindrical storing section and taper blanking section, cylindrical storing section is provided with material observation window, screen pack is provided with in cylindrical storing section inner chamber, taper blanking section is provided with baiting valve, taper blanking section is also connected with Pneumatic vibrator, screw rod is provided with in machine barrel inside, machine barrel outside is provided with heater, the pitch of screw rod is increased to extrusion die gradually by loading hopper, the end of described machine barrel is movably set with multiple extrusion die, multiple extrusion die is evenly distributed on the end of machine barrel, junction between extrusion die and machine barrel is provided with sealing ring.
As further program of the utility model: described cylindrical storing section is provided with lid.
As further program of the utility model: the quantity of described extrusion die is 4.
Compared with prior art, feed hopper set by the utility model comprises cylindrical storing section and taper blanking section, taper blanking section is connected with Pneumatic vibrator, the material be bonded on loading hopper sidewall can be shaken during Pneumatic vibrator work, material cannot be deposited on loading hopper sidewall, thus make extruder blanking unobstructed, without blocking, in addition, in the end activity of machine barrel, multiple extrusion die is set, overcome the shortcoming under basic efficiency of the prior art, simultaneously, junction between die head and machine barrel is provided with sealing ring, can prevent machine barrel from leaking gas, make the speed of Screw Extrusion faster, the product extruded is better.
