Hub drying method, hub drying machine and hub conveyor unit

Abstract

The invention discloses a hub drying method. A plurality of thin hubs are conveyed into a drying cavity in sequence from an inlet of a hub drying machine, the thin hubs are subjected to repeated staggered rotation and heated to be dried in the drying cavity, and finally the thin hubs are conveyed out from an outlet. The invention further discloses the hub drying machine. A hub conveyor unit is arranged in the drying cavity of a machine body, the hub conveyor unit comprises at least three shaft sets arranged in the vertical direction at intervals, and each shaft set comprises two rotation shafts arranged front and back in a spaced mode and flexible rotation parts which entangle the two rotation shafts. A conveying gap used for clamping thin hubs to move forwards is left between every two adjacent shaft sets, and a steering mechanism used for clamping the thin hubs, and making the hubs to be guided to the next conveying gap from the current conveying gap is arranged at the tail end of each conveying gap. According to the hub drying method, the hub drying machine and the hub conveyor unit, the drying time of the thin hubs in the drying cavity is prolonged, the utilization rate of thespace is improved, the production efficiency is improved, and the hub drying method, the hub drying machine and the hub conveyor unit can be used for drying the thin hubs.

Description

technical field [0001] The invention relates to the raw material drying field of wood plywood and wood-based panels, in particular to a wood chip drying method and equipment used therein. Background technique [0002] Thin wood chips are often used in the production of furniture, but the raw wood itself has moisture after being planed into thin wood chips in forest farms and wood factories, and wood chips that have been stored for a long time and have been damp are also relatively wet, so they must be dried. Natural drying takes too long, and it is greatly affected by the weather and takes up a lot of space, so it is best to use a wood chip dryer. The wood chip dryer consists of a body with a drying chamber. The wood chips are input from the entrance of the drying chamber, output from the outlet, and pass through an environment with a large amount of hot air blowing in the middle. The hot air flow fills the drying chamber, and the wood chips can be dried. . However, the tr...

AI Technical Summary

Problems solved by technology

[0003] 1. The wood chips move slowly in the drying chamber, which will inevitably reduce the drying efficiency, but if the conveying speed is increased, the residence time of the wood chips in the drying chamber will be short, and the ideal drying degree cannot be achieved.

[0004] 2. The wood chip itself is light and thin, and it is easy to be blown away. How to hold it firmly is a technical problem that the dryer must solve
