Problems solved by technology

However, this method still needs to use special tools to complete the gap adjustment between the ring die and the pressure roller in the shutdown state, and does not solve the problem of non-stop adjustment of the gap between the ring die and the pressure roller

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0029] figure 1 It is a schematic diagram of an embodiment of a moving-roller ring die granulator. The moving-roller ring die granulator mainly includes a ring die 8 and a pair of parallel left press rollers 3 and right press rollers 6 arranged horizontally in the ring die 8. , the gaps between the left pressure roller 3 and the right pressure roller 6 and the inner surface of the ring die 8 are not greater than 2 mm. The ring die bearing seat 1 is vertically fixed on the base 13. The ring die bearing seat 1 is fixed inside, and the inner circle of the ring die 8 and the ring die bearing 2 is fixedly connected to form a rotational connection between the ring die 8 and the ring die bearing seat 1 . When the material enters the gap between the ring die 8 and the pressure roller, the ring die 8 also rotates clockwise under the action of fric...

Abstract

The invention belongs to the technical field of feed forming and processing, and relates to a moving roller-type circular mould granulator. The moving roller-type circular mould granulator mainly comprises a circular mould and a pair of parallel left compression roller and right compression roller horizontally arranged in the circular mould, wherein the left compression roller and the right compression roller are coaxially and fixedly connected with the middle parts of a left compression roller spindle and a right compression roller spindle; the left compression roller spindle and the right compression roller spindle are rotationally connected with a left compression roller support saddle and a right compression roller support saddle through bearings respectively; the compression roller spindle and the right compression roller spindle are independently driven by a left compression roller spindle drive motor and a right compression roller spindle drive motor respectively, and independently adjust a gap between the left compression roller and the right compression roller and the circular mould through compression roller sliding screw pairs respectively. The compression rollers disclosed by the invention are driving structures; the circular mould is a driven structure and the compression rollers and the circular mould are independently arranged on a base, thereby achieving adjustment of the gap between the circular mould and the compression rollers in a shutdown or non-shutdown state, avoiding cross contamination of the feed and butter, and being suitable for granulating of biomass raw materials such as the feed, sawdust, straw and the like.

Description

technical field [0001] The invention belongs to the technical field of feed forming and processing, and in particular relates to a moving roller type ring die granulator. Background technique [0002] Ring die pellet mill is a machine that can extrude powdery materials into pellets, and it is widely used in feed production. Its structure mainly includes a ring die and pressure rollers. The ring die is in the shape of a hollow cylinder. There are several die holes drilled on the ring die. Generally, there are 2 or 3 groups of pressure rollers, which are evenly distributed inside the ring die. The granulator is divided into dynamic mode and dynamic roller type according to the motion characteristics. There are two types of dynamic mode and dynamic roller type in the flat die granulator. The existing ring die granulators are all designed with dynamic mode. When the ring die rotates, the material is pushed into the gap between the ring die and the pressure roller. Under the act...
