Mulberry twig bark and core stripping machine

Abstract

The invention discloses a novel mulberry twig bark and core stripping machine. The mulberry twig bark and core stripping machine comprises a bark stripping device and a raw bark bin located under an outlet of the bark stripping device. The bark stripping device comprises two sets of spiral rollers, wherein left-hand threads and right-hand threads with the thread pitch being 8-10 mm and the spiral angle being 20 degrees are arranged on the peripheral surfaces of the upper spiral roller and the lower spiral roller of each set respectively, the normal interval between the upper roller and the lower roller of the first set is 5-8 mm, and the normal interval between the upper roller and the lower roller of the second set is 4-5 mm. The mulberry twig bark and core stripping machine overcomes the defects that a manual bark stripping method is high in labor intensity and low in work efficiency, an existing bark stripping machine easily causes the situation that mulberry twigs are crushed too mush, is poor in mulberry twig completeness and is serious in damage to fibers, and mulberry barks and the mulberry twig chips can not be separated easily. The mulberry twig bark and core stripping machine adopts a simple mechanical structure and a new design principle, the mulberry barks are broken, separated and stripped on the mulberry twigs due to the twisting force and the tearing function of the left-hand and the right-hand threads on the mulberry twigs, the bark stripping effect is good, the bark and core separating rate can reach 90 %, damage to fibers is small, and the economic value of mulberry barks is improved.

Description

technical field [0001] The invention relates to the field of mulberry branch processing, in particular to a mulberry branch cortex stripping machine. Background technique [0002] Mulberry is a perennial herb with a planting history of more than 3,000 years in China. After the mulberry leaves are harvested each season, in order to maintain the nutrients of the mulberry tree and the land, the mulberry tree must be cut in summer and pruned twice a year. , About 700kg of fresh mulberry bark can be stripped from the discarded mulberry branches per mu of mulberry field, and the original mulberry bark fiber can be extracted by using the mulberry bark. Mulberry fiber is a kind of pure natural green fiber, which has the characteristics of flexibility, moderate density, strong plasticity, excellent moisture absorption, breathability, and warmth retention. It is a raw material for green textiles or ecological textiles. At present, the commonly used methods of peeling mulberry branche...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned technical defect of manually or mechanically stripping mulberry bark, and improve through repeated experiments to provide a new type of mulberry bark core stripping machine. The separation rate of the cortex and core of the mulberry branches is improved, and the integrity of the stripped mulberry bark is better, and the fiber damage is small, which improves the economic value of the mulberry bark
