Problems solved by technology

Existing mulberry branch peeling method or adopt artificial peeling, labor intensity is big, efficiency is low, and peeling quality is poor; The branch debris is not easy to separate, and the fiber damage is large
Moreover, most of the existing machines do not have the functions of taking the bark of mulberry branches and granulating the core rod in one step.

Embodiment 1

[0017] Feed several mulberry strips side by side to the feeding trough 1 with the big end in front, and enter the peeling device 2 under the action of the peeling roller. Peeling device 2 is made up of two groups of spiral rollers. Each set of upper and lower rollers is provided with left-handed and right-handed screw teeth on the outer surface of the rollers, and the two sets of spiral rollers are equipped with pressure-adjustable elastic springs. Feeding the mulberry branches, under the moderate pressure of the spiral roller and the reverse twisting force and tearing of the left and right-handed tooth bodies, the mulberry bark will be cracked and peeled off from the branches, and the branches will not be caused by excessive force. The stems are excessively broken, making it difficult to separate the bark from the stems. The mulberry branches after the preliminary separation of the bark and the bark move forward under the action of the rollers and enter the return chute 3, a...

Embodiment 2

[0019] In order to give full play to the technical advantages of the present invention, on the basis of Example 1, this embodiment further optimized the structural parameters of the skin-core separation device in the mulberry branch skin-core separation and granulation combined machine through multiple tests. Design, including the pitch, helix angle, normal spacing of the first and second sets of rollers, etc. of the surface threads of the spiral rollers in the peeling device 2

[0020] In order to obtain the pitch parameters of the optimal spiral roller thread, the present invention trial-produces a spiral roller with a helix angle of 20° and a pitch of 5mm, 8mm, 10mm, and 12mm, and carries out the spiral roller pitch on the mulberry bark core separation and granulation combined machine Effect experiment on the separation effect of mulberry bark and core. The normal spacing of the first and second sets of spiral rollers are respectively 5mm and 4mm. During the experiment, th...

Embodiment 3

[0037] On the basis of Example 1, this embodiment further optimizes the design of the structural parameters of the granulation device of the mulberry bark core separation and granulation combined machine through a number of specific tests, including the axial tooth height on the surface of the truncating roller 8 , tooth pitch, lateral displacement distance of smooth roller 9, and normal distance between cut-off roller 8 and smooth roller 9, etc.

[0038] In order to obtain the optimal tooth height parameters of the axial triangular spur teeth on the surface of the cut-off roller 8, cut-off rollers with a tooth pitch of 8mm and a tooth height of 2mm, 4mm, 6mm, and 8mm were trial-produced in this embodiment, and the axial tooth height was adjusted. Influence experiment of granulation effect. The lateral displacement distance of the smooth roller 9 is designed to be 3 mm, and the normal distance between the cut-off roller 8 and the smooth roller 9 is 1 mm. During the experiment,...

Abstract

A mulberry twig bark and core separation and granulation combined machine comprises a bark and core separation device and a mulberry twig granulation device, wherein a transferring roller is arranged between the bark and core separation device and the mulberry twig granulation device. The mulberry twig bark and core separation and granulation combined machine is good in bark and core separation quality, the separation rate can reach 90%, separated mulberry barks are complete in shape, is small in damage to fibers and contains few impurities like wood chips, manufactured core rod aggregate particles are uniform in size, contain a little dust and a few large-particle materials, and can meet the process requirements on raw materials when mulberry extraction fibers and core rod aggregates are directly used for producing mulberry twig fiber boards, paper and fungus culture media, and the comprehensive utilization rate of the mulberry twigs is high. The mulberry twig bark and core separation and granulation combined machine is high in mechanical continuity degree, only the mulberry twigs are fed manually, product transportation, mulberry twig bark and core separation, mulberry bark collection, core rod granulation and collection and links between the work procedures are all automatically and continuously finished by equipment, a little work time is used, and production efficiency is high.

Description

technical field [0001] The invention relates to the field of mulberry branch processing, in particular to a combined machine for separating and granulating mulberry branch skin and core. Background technique [0002] Mulberry trees have been planted in my country for thousands of years. They are perennial herbaceous plants. After the mulberry leaves are harvested each season, in order to maintain the nutrients of the mulberry trees and the land, the mulberry trees must be cut in summer, pruned in winter, and pruned every year. 2 times. According to the data, about 700kg of fresh mulberry bark can be stripped from the discarded mulberry branches per mu of mulberry field to prepare mulberry fiber. The peeled mulberry core rods can be used as raw materials for papermaking, high-quality furniture boards, high-strength composite floors, and culture media for edible fungi. Existing mulberry branch peeling method or adopt artificial peeling, labor intensity is big, efficiency is l...
