Background technology
Screw extruder is a kind of common extruder equipment, for plastic processing industry.Screw extruder has underframe, screw rod, feeding cylinder, packing cylinder, transmission case and die head, reductor and motor.Charging extruding device as screw extruder comprises underframe, transmission case body, screw rod, feed barrel and material extrusion cylindrical shell, on feed barrel, be provided with feed hopper, feed barrel front and back ends is connected with transmission case body, material extrusion cylindrical shell respectively, screw rod in feeding cylinder and packing cylinder, the driving member driven rotary of screw rod in transmission case.When a collection of materiel machining finishes to change different materials, need to remove the salvage stores being bonded on screw rod, the screw rod of some screw extruder can not dismounting, just needs to adopt new material is filled into the method for extruding salvage stores in screw rod, and the waste of material is larger.The screw rod of some screw extruder is can dismounting, but the dismounting of screw rod bothers very much, not only wastes time and energy, once install not in placely, affects the performance of extruder.
Utility model content
The purpose of this utility model is to propose a kind of for removing the screw extruder charging extruding device that on screw rod, salvage stores is provided convenience.
For achieving the above object, the utility model is taked following technical scheme: this device comprises underframe, transmission case body, screw rod, feed barrel, material extrusion cylindrical shell, feed barrel is provided with feed hopper, screw rod is in feed barrel and material extrusion cylindrical shell, underframe is provided with line slideway, feed barrel and material extrusion cylindrical shell are separately fixed on feeding rack and material extrusion frame, feeding rack and material extrusion frame can move by the slide block separately on the line slideway of underframe, between transmission case body and feed barrel and between feed barrel and material extrusion cylindrical shell, by bindiny mechanism, connect.
Between described transmission case body and feed barrel, between feed barrel and material extrusion cylindrical shell, all by flange, connect, all flanges have the edge of right-angled trapezium section, the edge of two flanges that combine is merged into isosceles trapezoid flange, before feed hopper, before rear side and feeding rack, rear side is respectively provided with described bindiny mechanism, bindiny mechanism has oil cylinder and is connected to the jaw on cylinder piston rod, jaw has the isosceles trapezoid groove of the isosceles trapezoid flange coupling being merged into two flanges, the jaw of bindiny mechanism utilizes isosceles trapezoid groove to be stuck on corresponding flange flange two flanges is fixed together.
The utlity model has following good effect: each is carried feed barrel of the present utility model and material extrusion cylindrical shell by feeding rack and material extrusion frame, feeding rack and material extrusion frame can move on the line slideway of underframe, thereby drive feed barrel and material extrusion cylindrical shell to move, make outside screw rod is exposed to, carry out clear operation, after clear operation finishes, feed barrel and material extrusion cylindrical shell reset, for the salvage stores of removing on screw rod is provided convenience.Owing to not needing to consume new material, joint material is energy-conservation.Bindiny mechanism drives jaw to move by oil cylinder, utilizes the isosceles trapezoid groove of jaw to be stuck on corresponding flange flange two flanges are fixed together, easy to loading and unloading, connects reliably and fast, does not have the problem that affects extruder performance.
