Plant stem skin-core rapid separating device

Abstract

The invention discloses a plant stem skin-core rapid separating device which comprises a driving motor, a belt wheel, a roller support, an upper roller, a lower roller, a transmission gear, a spring compression device and a pre-tightening bolt. The plant stem skin-core rapid separating device is characterized in that the positions of the two ends of the upper roller are adjusted through the springcompression device, the surface of the upper roller and the surface of the lower roller are provided with spiral teeth, and the spiral teeth on the surface of the upper roller and the surface of thelower roller have inclined angles. The plant stem skin-core rapid separating device has the advantages that the stable radial force and axial force are formed in the rotating process of the rollers, plant stems can be squeezed and stripped, the squeezing strength can be adjusted to adapt to separation of the plant stems with different bast strength, the plant stem skin-core rapid separating deviceis reasonable in structure and remarkable in separation effect, saves cost and has quite high controllability and practicability, and the working process is flexible and convenient.

Description

technical field [0001] The invention relates to the technical field of plant stalk peeling treatment, in particular to a device for quickly separating the bark and core of plant stalks. Background technique [0002] my country is the main producer of cotton and linen textiles, and there is a huge demand for raw material processing of cotton and linen. Pure natural plant fibers come from plant stems, which are composed of bast and rod cores, and the bast is a natural textile fiber raw material after degumming. Among natural fibers, hemp fiber has the broadest development prospects. Hemp fiber is obtained from the bast of hemp plants. From the analysis of fiber length, fineness and spinnability, ramie, hemp and flax can be used as textile raw materials. In order to extract the natural fibers in the plant stalks, it is necessary to separate the bast on the stalks from the core. The traditional separation method is generally carried out manually. Damage to the stalks prevents ...

Problems solved by technology

For example, the three devices described in the patent 2015108718058 hemp fresh stem peeling machine, 201510913114X industrial hemp peeling machine, and 2015109132566 kenaf jute peeling machine all send hemp stalks into the peeling drum for crushing by rollers to achieve the peeling of the stalks. , bone separation, but these devices have a common defect. The hemp stems are rolled by toothed rollers. Although the core of the hemp stems can be broken, the bast fibers are still agglomerated and not divided. Thin strands, while the bast fiber will be broken or crushed during the rolling process, affecting the quality and integrity of the bast fiber

[0003] Due to the inconsistent toughness of the plant stem epidermis, if a corresponding skin-core separation device is provided for each plant, it will not only increase the production cost, but also be unfavorable to the operation
