Granulating machine with double-ring mould built-in

Abstract

The invention discloses a double-ring die built-in granulating machine in the granulating machine field, comprising a frame and a ring die, wherein, a plurality of die holes are radially arranged on the wall of the ring die; one end of the ring die is provided with a feeding channel; a main sleeve is fixed on the frame; the other end of the rind die is fixed with a belt pulley which is arranged outside the main sleeve through a bearing; a cylindrical inner ring die is arranged in the ring die; a plurality of radial die holes are also arranged on the wall of the inner ring die; one end of the inner ring die is connected with a rotating shaft which is arranged in an adjusting sleeve; the adjusting sleeve is arranged on a machine body; a feeding shaft is arranged on the main sleeve, axially passes through a clearance between the ring die and the inner ring die and extends into the feeding channel, and is provided with a helical propelling blade; and the helical propelling blade extends from the lower side of a feeding port of the feeding channel to the clearance between the ring die and the inner ring die. The double-ring die built-in granulating machine has the plurality of the die holes, can simultaneously granulate on the ring die and the inner ring die with high work efficiency, and can be used for granulating in foodgrain processing and fodder processing.

Description

technical field [0001] The invention relates to a grain feed machine, in particular to a ring die granulator. Background technique [0002] In the prior art, there is a ring die granulator, which includes a frame and a cylindrical hollow ring die, a number of die holes are radially provided on the wall of the ring die, and a feeding channel is radially provided at one end of the ring die. The ring die is connected with the power input mechanism through the transmission system. There is at least one pressure roller inside the ring die. The pressure roller is rotatably installed on the pressure roller fixing mechanism. When working, the ring die rotates and the material enters the ring die from the feeding channel. Driven by the ring die, it continuously passes between the pressure roller and the ring die. Under the extrusion of the pressure roller, the material is extruded from the die hole and cut by the cutter device to form a granular material; The disadvantage is: this g...
