Description
Technical field
The present invention relates to a kind of kneading cutter, relate in particular to a kind of cutter of applying in extrusion equipment in feed and food processing field, i.e. bulking machine kneading cutter.
Background technology
In food and feed processing industry, bulking machine is a kind of Extruding equipment of commonly using, in feed extrusion machinery field, the raising requiring along with scientific and technological progress with to feed processing quality, in feed machine process, need material to shear by force, need again material to push, and traditional extruder work in-process, owing to lacking so a kind of cutter, and make the transfer efficiency of material in extruder low, some bulking machines have shearing force but propelling movement power deficiency, some bulking machines have propelling movement power and shearing force deficiency etc., finally cause the bad or low inferior problems of production capacity of feed quality.Therefore, the bulking machine of a kind of function that can have the shearing to material concurrently and push forward in extrusion production process of exigence.
Summary of the invention
The present invention is just for the technical problem existing in prior art, provide a kind of simple in structure, easy to operate, lower-cost bulking machine kneading cutter, this kneading cutter has the function pushing forward in carrying out kneading shearing, improve the production efficiency of bulking machine, improve feed quality, extended the service life of consumable accessory, reduced the production cost of enterprise.
To achieve these goals, technical scheme of the present invention is as follows: a kind of bulking machine kneading cutter, it is characterized in that, described kneading cutter comprises material guide port, storage sword, rotary-cut sword, kneading sword, slow kneading groove, fast kneading groove, discharge port, discharging sword, cutter hub cylindrical, above-mentioned each parts arrange in groups, its number is two groups, every group of circumference uniform distribution at described kneading cutter; Described kneading cutter also comprises interior installing hole, feeding end, discharge end; Described material guide port and storage sword are positioned at feeding end; Fast kneading groove in described same group and slow kneading groove originate in the material guide port of this group jointly, and respectively in discharge port and the slow kneading groove in another group, the crossing position termination of fast kneading groove; Described rotary-cut sword is positioned at the angle of fast kneading groove and slow kneading groove initiating terminal; Described fast kneading groove pitch is greater than slow kneading groove pitch; Described kneading sword is positioned at storage sword on the same spiral of discharge port direction extension, and described discharging sword is positioned on the spiral of discharge port, and described discharging sword is positioned at discharge end; Described cutter hub cylindrical is coaxial with interior installing hole.
Rotary-cut sword completes the forward operation to complete material after the cutting of material by the cooperation of kneading sword and fast, slow kneading groove;
Material enters the continuation rotation along with kneading cutter after discharge port, enters discharging end face by discharging sword, completes the output function of material.
As a modification of the present invention, described slow kneading groove becomes multiple relation with the pitch of fast kneading groove, and its pitch ratio is 1:2, and the discharge rate of slow kneading groove and fast kneading groove is 1:2.
As a modification of the present invention, described cutter hub cylindrical is set to cylindrical or conical structure.
Above-mentioned interior installing hole is set to the one in hexagonal hole or square hole or splined hole or circular hole.
With respect to prior art, advantage of the present invention is as follows, 1) this kneading cutter improves feed quality, improves expanded production efficiency, and because the extrusion process of material is a state that HTHP is constant, traditional bulking machine in process of production, because it has adopted triangle resistant block, make the comparison of resistance of material in bulking machine large, therefore reduced its production capacity, and output is larger, pressure in bulking machine is just larger, and resistance also just increases thereupon.The utilization of kneading cutter of the present invention, in bulking machine, reduce its resistance, under the cooperation of rotary-cut sword, kneading sword, speed kneading groove, greatly promote the conveying capacity of material and sheared kneading ability, make the abundant kneading mixing of material slaking more even, effectively guaranteed the raising of bulking machine output and the lifting of expansion effect; 2) reduce friction, extend service life of consumable accessory, under normal circumstances, triangle resistant block in common bulking machine is because not carrying effect, and very large of material and triangle resistant block friction, is fed forward by back segment spiral pushing material, can cause like this wearing and tearing of consumable accessory very fast, need to change frequently, the utilization of structure of the present invention, has reduced its friction, greatly extended the service life of consumable accessory, reduce the production cost of enterprise;
3), reduce Feed Manufacturing cost, due to the raising of output, reduce the ton of expanded pellet diet and produced power consumption, and compared with prior art, produce the feed of as much, the used time is still less, extend the service life of consumable accessory, the wear and tear expense of material consumable accessory per ton still less, has been saved the production cost of enterprise greatly, is convenient to large-scale utilization and extention; 4), wide accommodation, the application of this product can obtain better expansion effect, and can be applied in the production of various expanded pellet diets and dilated food; 5).Overall structure is simple, convenient processing and manufacture, the manufacturing cost that reduces.
