Description
Technical field
Extruder technology field is the utility model is related to, more particularly to a kind of automatically cleaning extrusion mechanism.
Background technology
The extrusion screw rod of existing extruder connects generally by the rotating shaft of shaft coupling and motor, and shaft coupling is in addition
Side is exactly extrusion screw rod, and such extrusion screw rod is very easy to be gathered in shaft coupling and extrusion screw rod during powder is extruded
Between corner in, be not easily cleaned out；And because shaft coupling carries antirust oil, these antirust oil easily overflow pollution powder
Material；In addition, when the powder of front and rear extrusion different colours, powder of the powder easily with other colors remained in corners mixes
Close, so as to influence the color and luster degree of purity of powder.
Utility model content
In order to solve the above technical problems, the utility model discloses a kind of automatically cleaning extrusion mechanism, including extrusion screw rod, spiral shell
Set, feeding hopper, motor, shaft coupling and blowdown screw shell, the extrusion screw rod are arranged in swivel nut, the driving electricity
Machine is connected by shaft coupling and extrusion screw rod, and the swivel nut is provided with charging aperture, and the feeding hopper connects with charging aperture, institute
State shaft coupling to be arranged on close to the position of charging aperture in swivel nut, the blowdown screw shell is arranged on outside shaft coupling and can followed
Shaft coupling rotates, and the thread rotary orientation of the blowdown screw shell and the thread rotary orientation of extrusion screw rod on the swivel nut on the contrary, be located at
The exhaust end of blowdown screw shell is provided with sewage draining exit, and the sewage draining exit is detachably connected with feculence box.
As the further improvement of above-mentioned technical proposal, the both sides on the swivel nut positioned at sewage draining exit are provided with neck, described
The upper surface of feculence box two side is provided with buckle, and the feculence box is connected with sewage draining exit by buckle and neck.
As the further improvement of above-mentioned technical proposal, the pitch of the extrusion screw rod is more than the spiral shell of blowdown screw shell
Away from.
As the further improvement of above-mentioned technical proposal, the extrusion screw rod is screw thread facewidth 70mm rectangle screw rod.
The beneficial effects of the utility model are：
The utility model sets blowdown screw shell, the dirt that extrusion screw rod root is assembled on the shaft coupling of extrusion screw rod
Thing and impurity are discharged to the direction in opposite direction that discharges, and avoid greasy dirt and variegated powder from being discharged from the discharge end of extrusion screw rod,
So as to pollute raw material.
