Description
Technical field
The utility model relates to a kind of extruder, relates in particular to a kind of single screw extrusion machine.
Background technology
Single screw extrusion machine occupies critical role in plasticizing processing, screw rod is as the critical component of single screw extrusion machine, and its effect is most important, and screw rod is one of the most important factor of the efficient of decision extruder.Simultaneously, for ease of carrying out smoothly of the whole production procedure of single screw extrusion machine, if solid material is because of the generating portion liquefaction of being heated in loading hopper feeds in raw material process to barrel, then in the transport process of material, can cause unnecessary impact, and Yin Wendu reduces generating portion curing in the transmission course after solid material liquefaction, then the transmission of material caused unnecessary impact with use, with this, the problem during these are produced should be solved.
The utility model content
The purpose of this utility model provides a kind of single screw extrusion machine and solves for ease of the carrying out smoothly of the whole production procedure of single screw extrusion machine, how to avoid unnecessary curing or liquefaction and problem how.
Technical solution of the present utility model is:
A kind of single screw extrusion machine, comprise motor, reductor, barrel, screw rod and loading hopper, described motor connects described reductor, described reductor connects described screw rod, and described loading hopper is located on the described barrel, and the feed end of described barrel is wrapped with cooling jacket, described barrel is provided with heater, described barrel also is enclosed with insulation jacket outward, and the end of described barrel is provided with discharging opening, is provided with described screw rod in the described barrel.
Further improve and be: described screw rod is not for equidistantly waiting dark screw rod, and the diameter of described screw rod is 30mm-45mm.
A kind of single screw extrusion machine of the utility model, by motor the screw rod in the barrel is carried out transmission, make screw rod drive material in the barrel and carry out spiral along screw channel and advance, for regulating the load of single screw extrusion machine, use reductor that the screw rod in the barrel is carried out speed governing simultaneously.Loading hopper is set on the barrel extruder is fed in raw material, the outer wrap cooling jacket at the feed end of barrel cools off loading hopper.The screw rod of this kind single screw extrusion machine is provided with solid conveying zone, melting zone, melt Conveying district successively, screw rod at solid conveying zone will move from the solid material of loading hopper input, and make solid-state material transfer liquid material at melting zone by the heating to solid material, and simultaneously in the outer wrap of barrel insulation jacket is arranged, avoid liquid material to produce unnecessarily and solidify prematurely.Screw rod is not for equidistantly waiting dark screw rod, and the diameter of described screw rod is 30mm-45mm, and the diameter of screw rod increases so that the output of extruder obviously increases, so will obtain high output, this is one of the most effective means.
The beneficial effects of the utility model are: a kind of single screw extrusion machine of the utility model, reasonable in design can realize different extruded velocities according to different Production requirements, thereby is convenient to produce.This kind single screw extrusion machine is provided with cooling jacket and insulation jacket simultaneously, more utilize and produce, cooling jacket can guarantee the smooth delivery of power of solid material, insulation jacket guarantees the high efficiency of solid material liquefaction, and avoided the unnecessary curing of material after the liquefaction, thereby guaranteed the carrying out of production procedure.
