Description
Technical field
The utility model relates to rubber production apparatus field, is specially a kind of feed worm extrusion mechanism of rubber.
Background technology
Rubber is raw material conventional in industry, according to different applications, can use the rubber of difference in functionality and composition, in the production process of many rubber, rubber and other various materials need to be merged to plasticizing, often need now screw extruder to complete this task.
But present screw extruder does not have exhaust structure more, alveolate existence in the rubber that causes extruding, affects the quality of the product of later stage moulding; In addition, some being mixed in rubber is solid particle or the material that makes strip, easily makes screw deadlocking when extruding, and also easily blocks the situation of not blanking in charging in feed hopper.
Utility model content
Technical problem to be solved in the utility model is to design a kind of feed worm extrusion mechanism of rubber, is provided with exhaust section on screw rod, prevents from occurring in rubber pore, and occurs stuck situation when being prevented charging and being extruded by built-in and external structure.
For solving the problems of the technologies described above, the utility model provides a kind of feed worm extrusion mechanism of rubber, comprise and extrude housing, extrusion screw rod and feed hopper, the described inner transverse of extruding housing is furnished with extrusion screw rod, its upper end is provided with feed hopper near the position of right-hand member, its left side has plastic hole between two parties, one end of described extrusion screw rod is for aiming at the taper extruder head of plastic hole, the inner face of extruding housing corresponding with extruder head is circular cone spigot surface, some arcuate guide convex tendons on this circular cone spigot surface, centered by plastic hole, have been evenly arranged, location arrangements near extruder head on described extrusion screw rod has exhaust section, the diameter of this exhaust section is less than the diameter of extrusion screw rod, corresponding with the position of exhaust section extruding is circumscribed with vacuum extractor on housing.
The diameter of exhaust section is less than the diameter of extrusion screw rod, makes extruded rubber have the operation of bleeding of sufficient space at exhaust section, discharges inner pore; When on circular cone spigot surface, arcuate guide convex tendon makes to extrude, mixed rubber body is extruded from the strip region guiding between adjacent arcuate guide convex tendon, and converges in plastic hole, and guidance quality is good, prevents stuck situation.
As a kind of supplementing of the present utility model, the upper end open place of described feed hopper is provided with a pair of reel side by side, the auxiliary material of the rubber of processing and mixing is put on feed hopper simultaneously, and by relatively rotating of reel, compound is carried out to preliminary mixing, be unlikely to block at the feed opening of feed hopper.
As another kind of the present utility model, supplement, the downside of described feed hopper is provided with taper strand material screw rod, and taper strand material screw rod is descending carries out preliminary mixing extruding by compound, prevents the situation that the feed opening of feed hopper is blocked.
Further, the described left end of extruding housing is furnished with the mould docking with plastic hole, and mould makes the mixed rubber energy rapid shaping of extruding, and facilitates the scene that whole extrusion device is used at product to use, and the product of producing can be used at once.
The feed worm extrusion mechanism of rubber described in the utility model, is provided with exhaust section on screw rod, prevent from occurring in rubber pore, and occurs stuck situation when being prevented charging and being extruded by built-in and external structure.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described in detail.
Fig. 1 is that master of the present utility model is depending on partly cuing open structure chart;
Fig. 2 is that the master of circular cone spigot surface described in the utility model looks amplification assumption diagram.
The specific embodiment
As shown in Figure 1-2, a kind of feed worm extrusion mechanism of rubber, comprise and extrude housing 1, extrusion screw rod 2 and feed hopper 7, the described inner transverse of extruding housing 1 is furnished with extrusion screw rod 2, its upper end is provided with feed hopper 7 near the position of right-hand member, its left side has plastic hole 6 between two parties, one end of described extrusion screw rod 2 is for aiming at the taper extruder head 3 of plastic hole 6, the inner face of extruding housing 1 corresponding with extruder head 3 is circular cone spigot surface 5, some arcuate guide convex tendons 10 on this circular cone spigot surface 5, centered by plastic hole 6, have been evenly arranged, location arrangements near extruder head 3 on described extrusion screw rod 2 has exhaust section 4, the diameter of this exhaust section 4 is less than the diameter of extrusion screw rod 2, be circumscribed with vacuum extractor with corresponding the extruding on housing 1 in position of exhaust section 4.
The upper end open place of described feed hopper 7 is provided with a pair of reel 9 side by side, the auxiliary material of the rubber of processing and mixing is put on feed hopper 7 simultaneously, and by relatively rotating of reel 9, compound is carried out to preliminary mixing, be unlikely to block at the feed opening of feed hopper 7.
The downside of described feed hopper 7 is provided with taper strand material screw rod 8, and taper strand material screw rod 8 is descending carries out preliminary mixing extruding by compound, prevents the situation that the feed opening of feed hopper 7 is blocked.
The described left end of extruding housing 1 is furnished with the mould docking with plastic hole 6, and mould makes the mixed rubber energy rapid shaping of extruding, and facilitates the scene that whole extrusion device is used at product to use, and the product of producing can be used at once.
Embodiment
