Spiral n-shaped material friction rotating cage

Abstract

The invention relates to a spiral n-shaped material friction rotating cage. The rotating cage comprises a rotating cage shaft and the friction rotating cage body composed of a rotating cage upper section and a rotating cage lower section; the rotating cage shaft is arranged at the center of the rotating cage upper section and the rotating cage lower section, and the rotating cage shaft is connected with a driving device; the rotating cage shaft is fixedly connected with multiple layers of connecting rods, the connecting rods of the rotating cage shaft is connected with a section bar circular ring through connecting plates, and n-shaped straight-strip frameworks are connected to the section bar circular ring through special-shaped connecting plates; and a lap joint is formed between every two adjacent n-shaped straight-strip frameworks, and equal-length plastic protective strips are arranged on the outer sides of the n-shaped straight-strip frameworks. The rotating cage has the advantages that the overall rigidity of the periphery of the rotating cage is improved, gaps between every two adjacent straight-strip frameworks are reduced, the overall rigidity of the rotating cage is improved, the difficulty of cleaning the rotating cage is reduced, and the sanitary grade of the rotating cage is improved.

Description

technical field [0001] The invention relates to a friction tumbler, in particular to a friction tumbler with a spiral shape for fast freezing, cooling and transporting food. Background technique [0002] At present, in the friction drum of the spiral freezing device, the positions of the "n" type straight skeletons on the friction drum are all single, and there are certain gaps between them, which will lead to insufficient rigidity of the straight skeletons. When the belt is faulty, the mesh belt and the outer side of the cage will be stuck, which will hinder the rotation of the cage, and the overturned mesh belt will damage the wear-resistant plastic parts and generate bending torque on the cage. Before the overload protection is triggered, the bending torsion will damage a certain number of "n" type straight frames; at the same time, due to the existence of gaps, cleaning is difficult and the sanitary conditions of the cage are affected.
