Description

Automatic peeling machine for bark

Technical Field

The invention relates to the technical field of bark peeling, in particular to an automatic bark peeling machine.

Background

The bark refers to root bark, trunk bark, branch bark, etc., which refers to cortex in the narrow sense and refers to all tissues except for stratified layers in the broad sense, including soft bark and hard bark. The bark of many bark plants can be used as raw material for preparing Chinese medicinal materials, such as cortex Magnolia officinalis, Eucommiae cortex, cortex Phellodendri and cortex Cinnamomi. When bark plants are used as medicinal raw materials to be processed, fresh barks of the bark plants need to be peeled off and then dried in the sun or baked. Generally, when the plants are processed, a manual peeling method is adopted, and manual peeling not only causes low peeling efficiency, but also increases the labor intensity of workers and peeling cost.

In order to solve the above problems, there are many apparatuses for peeling in the prior art. Chinese-medicinal material peeling device is disclosed for CN201910466203.2 like patent application number, including box one, shale shaker and peeler, box one includes the preliminary treatment chamber, peeling chamber and stoving chamber, the preliminary treatment intracavity is equipped with the hair roller, the preliminary treatment chamber top is equipped with pan feeding mouth one and water pipe, be equipped with the nozzle on the water pipe, preliminary treatment chamber bottom is equipped with pan feeding mouth two, the preliminary treatment chamber passes through pan feeding mouth two and peels the chamber intercommunication, peeling intracavity is equipped with peeling roller and desquamation board, peeling roller one end is connected with motor two and the other end is connected with box one, peeling chamber bottom is equipped with pan feeding mouth three, peeling board is located peeling roller and pan feeding mouth between three, peeling chamber passes through pan feeding mouth three and stoving chamber intercommunication, stoving chamber one side is equipped with drying equipment, stoving chamber bottom is equipped with pan feeding mouth four, the stoving chamber passes through pan feeding mouth four and shale shaker intercommunication, the peeler is connected to shale shaker one side.

The peeling device adopts the peeling roller to peel the traditional Chinese medicinal materials in the peeling cavity, replaces the traditional manual peeling method, and can only peel the barks with basically consistent length, shape and diameter although the peeling efficiency is improved. However, bark plants vary in shape, and may have a flat shape, a curved shape, a groove shape, a single roll shape, a double roll shape, or the like, and the size of the root diameter thereof varies significantly. When the device is adopted to peel bark plants with different shapes and root sizes, when the diameter of the bark plant is remarkably increased, the part with the larger root and the root on the bark plant cannot smoothly enter the peeling roller to be peeled, so that the peeling device cannot meet the requirements of peeling the bark with different shapes and sizes and remarkable change, and the peeling of the bark is carried out by beating different positions of the bark by a manual peeling method, so that the labor is wasted, a large amount of labor is needed, and the peeling effect, the peeling cost and the peeling efficiency are reduced.
