Description

An inner tooth drum material processing device with adjustable tooth spacing

technical field

The present application relates to a material processing device, in particular to a material processing device for an inner-toothed drum with adjustable inner tooth spacing of the drum teeth.

Background technique

Dried fruits or nuts can be processed and processed only after the pulp and peel covering the outside of the core are removed. The traditional method of removing the pulp and peel is generally manual peeling by workers or processing by composting. The efficiency of manual stripping is low, and the sharp stripping knives may cause injuries to workers during the stripping process; the efficiency of the composting method has been improved, but it covers a large area, and most of them use natural or artificial acceleration. The method is that the pulp and peel rot and fall off. During the rot, a large amount of harmful substances or harmful gases will be produced, which will cause adverse effects on the surrounding environment, and even pollute the environment and the health of operators.

With the advancement of science and technology, devices for mechanically removing pulp and peel have gradually appeared in the market. Most of these mechanical devices use mechanical external force to crush the pulp and peel located on the outside, smash or small pieces, and then carry out follow-up processing, such as High pressure water flushing, etc. The most widely used method is to process these fresh fruits in the form of processing rollers. The processing rollers are provided with roller strips and roller teeth, and the processing rollers are provided with a driving center shaft. The roller bars and roller teeth on the top handle and squeeze the fresh fruit located between the inner wall of the cabinet and the processing roller, squeeze and tear it, take off the pulp and peel, and leave the fruit core.

The size between the drum teeth in the treatment drum in the prior art mechanical treatment device is generally not adjustable, and each treatment drum has its specific spacing size, and this size can only be used to process a specific one. type of fresh fruit material. However, the types of fresh fruits that need to be processed in different seasons and periods will be different, and the stress conditions of different types of fresh fruits are also different. For example, the hardness of the pulp of almonds is smaller than that of green walnuts. The processing drum is used to process almonds, and the large processing force will damage the cores of almonds, which will lead to the decline of their grades. If this machine for processing green walnuts is required to process almonds, then new processing drums will need to be purchased, but if the processing period has passed, these newly purchased drums will be idle. Through research, it is found that the processing external force of the processing drum is directly related to the axial tooth spacing of the drum teeth set on the processing drum. If you want to adjust the processing external force of the processing drum, you need to adjust the axial spacing of the drum teeth, and The difference between different rollers dealing with external force in the prior art also mainly lies in the axial spacing of the roller teeth. However, the drum teeth on the treatment drum in the prior art are directly fixed on the surface of the treatment drum, and the drums with different treatment strengths have different spacings, which cannot be adjusted. It is a huge waste, and it also greatly increases the production cost for fresh fruit processing enterprises. Therefore, it is urgent to develop a pulping and peeling device with a processing drum with an adjustable drum tooth axial spacing.
