Problems solved by technology

[0002] In the food and feed processing industry, the extruder is a commonly used extruding equipment. In the field of feed extrusion machinery, with the advancement of science and technology and the improvement of the quality requirements for feed processing, in the process of feed processing, it is necessary to process materials For strong shearing, it is necessary to push the material. However, due to the lack of such a tool during the processing of the traditional extrusion extruder, the conveying efficiency of the material in the extrusion extruder is low. Some extruders have a shear Cutting force but insufficient pushing force, some extruders have pushing force but insufficient shearing force, etc., which eventually lead to many problems such as poor feed quality or low production capacity

Embodiment 1

[0020] see figure 1 , figure 1 Schematic diagram of the overall structure of the present invention, a kneading knife for an extruder, the kneading knife includes a material guide port 2, a storage blade 3, a rotary cutting blade 4, a kneading blade 5, a slow kneading groove 6, and a fast kneading groove 7. Discharge port 8, discharge blade 9, cutter outer circle 11, the above-mentioned components are arranged in groups, the number is two groups, and each group is evenly distributed on the circumference of the kneading knife; the kneading knife also includes Inner mounting hole 1, feed end 10, and discharge end 12; the material guide port 2 and the storage blade 3 are located at the feed end 10; the fast kneading groove 7 and the slow kneading groove 6 in the same group work together It starts from the material guide port 2 of this group, and terminates at the position where the discharge port intersects with the slow kneading groove and the fast kneading groove in the other g...

Embodiment 2

[0024] As another form of expression of the present invention, see figure 1 — Figure 6 , the screw pitch of the above-mentioned slow kneading tank 6 and the fast kneading tank 7 is in multiples, the pitch ratio is 1:2, and the unloading speed of the slow kneading tank 6 and the fast kneading tank 7 is 2:1. The pitch relationship of the fast and slow kneading grooves is set to 2:1, which further ensures the cooperation between the fast and slow kneading grooves, the rotary cutting blade and the kneading blade, thereby ensuring that the kneading knife has stronger kneading shear, further improving the The production efficiency of the extruder greatly improves the feed quality. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0026] As another form of expression of the present invention, the outer circumference 11 of the cutter is configured as a cylindrical or conical structure. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a kneading knife for an extruder. The kneading knife includes a material guide port (2), a storage blade (3), a rotary cutting blade (4), a kneading blade (5), a slow kneading groove (6) ), fast kneading tank (7), discharge opening (8), discharge blade (9), cutter outer circle (11), the above-mentioned components are set in groups, and the number is two groups, and each group is in the kneading The circumference of the kneading knife is evenly distributed; the kneading knife also includes an inner installation hole (1), an input end (10), and an output end (12); the fast kneading groove (7) and the slow kneading groove in the same group The kneading grooves (6) start from the material guide port (2) of this group, and end at the positions where the discharge port intersects with the slow kneading groove and the fast kneading groove in the other group; The blade (4) is located at the angle between the starting ends of the fast kneading groove (7) and the slow kneading groove (6); the pitch of the fast kneading groove (7) is greater than that of the slow kneading groove (6). The kneading knife of the invention improves the production efficiency of puffing and improves the quality of feed.
