Described screw propulsion cutting agency below is connected with the extruder that has heater, and the outer end of the extrusion screw rod of extruder is connected with extrudes power set; The output of extruder connects extruder head, and the extruder head output connects bosh, and the discharge end of bosh connects first carry-over pinch rolls and second carry-over pinch rolls successively.
The output of extruder connects extruder head by mixing supercharging device.
The version of described mixing supercharging device is screw form, and wherein screw rod overlaps the internal diameter unanimity, and screw shaft has two sections spiral leaf wing branches, preceding half section leaf wing spacing with less outside dimension and broad amplitude wherein; The leaf wing spacing that second half section has bigger outside dimension and spends more in a narrow margin.
Between first carry-over pinch rolls and second carry-over pinch rolls, be provided with the release treatment groove.
The output of second carry-over pinch rolls is connected with glue rod cutter sweep.
Good effect of the present invention is:
(1), since in the raw material of hot melt rubber stick each component molecular weight difference and distributional difference bigger, corresponding difference of specific gravity is also very big, if adopt the deadweight blanking, each component blanking speed difference, obviously irregular problem will appear in the material that enters extruder.The present invention is pushed into mixed material in the extruder by force by the screw propulsion cutting agency under dynamic action, has solved above-mentioned technical problem.
(2), around the screw propulsion cutting agency, be provided with and have the cooling water cycle water cover, can implement to cool to the mixed material in the screw propulsion cutting agency, avoid low-melting component in blanking channel, to melt, cause the irregular even obstruction cutting agency of blanking.
(3), the output of extruder connects extruder head by mixing supercharging device, can further carry out mixingly to material, and improves the pressure that extruded stock enters head, improves glue rod quality and production efficiency.Specifically, the form of mixing supercharging device is a screw form, and wherein screw rod overlaps the internal diameter unanimity, and screw shaft has two sections spiral leaf wing branches, preceding half section leaf wing spacing with less outside dimension and broad amplitude wherein; The leaf wing spacing that second half section has bigger outside dimension and spends more in a narrow margin; Front and back two segment length are suitable substantially.She Ji good effect is like this: preceding half section to be mainly used in material mixing for mixing supercharging device, extrudes and the second half section is mainly used in supercharging, and existing mixing effect has increased extrusion pressure again.
(4), have additional the release treatment groove that adds the antiseized chemicals of entry and glue rod, effectively prevent adhesion mutually between the glue rod.
(5), its whole structure is simple, compact conformation, floor space is little, and is easy to operate.
