(2) The dead bamboo, worm-eaten and moldy bamboo is not allowed.
(3) The length of each bamboo is not shorter than 5m, and the branch of the branch is required to be more than 2m away from the root.
(4) The bending degree of each bamboo is not more than 7%.
The materials, specifications and requirements of each cap shell are shown in table 1:
TABLE 1
The rough blank of the moso bamboo is finished by a special bamboo chip punching machine, and the width and thickness of the bamboo blank are determined by increasing the functions of width and thickness determination by a moso bamboo slicing machine; the bamboo blank slicing adopts a self-made assembly slicing machine set, one bamboo blank (3.2 m in length) is divided into four pieces, namely green, blue and yellow, the first three pieces are drawn into thin strips (a special drawing machine is used, one thin strip is divided into 6-7 thin strips) to be used as helmet wires for weaving the helmet shell, the thin strips (the specification: 3200 x 2.3 x 0.5mm) divided from the first green piece are used for weaving the top of the safety helmet due to the relatively good hardness, and the thin strips (the specification: 3200 x 2.7 x 0.8mm) divided from the second yellow piece and the third yellow piece are used for weaving the lower part and the brim part of the helmet shell. The fourth layer of yellow sheet is used as a reinforcing rib inside the hat shell. And sorting and bundling the processed thin stripes according to the quality and length, and weaving the hat shell. The tying of the hat brim directly relates to the problems of hat shell strength, attractive product appearance, production efficiency and the like, so that the improvement and optimization are urgently needed; the cap brim tying mainly solves the problems of completeness and smoothness of the cap brim and strength increase of the cap shell. Four sealed slight strips (specification 1050 x 2.4 x 2.5mm) are additionally arranged on the upper and lower parts of the bamboo strip, and plastic rattan skin is used for winding the slight strips one by one; after the helmet shell is qualified, the four layers of yellow sheets (specification: 350 × 25 × 1.5mm) are arranged according to 6 crossed and separated points at 60 degrees, and the shock resistance of the safety helmet is mainly improved. After the reinforcing ribs are installed, the top ribs are inserted continuously to further strengthen the impact resistance and the puncture resistance of the safety helmet, 6 thin bamboo strips (the specification: 100 x 10 x 1.2mm) are sequentially overlapped at the outer top of the safety helmet, and two ends of the thin bamboo strips are fixed at a jackscrew. The curing treatment step overcomes the defects of environmental protection and uncontrollable quality of the curing agent, and adopts the environment-friendly curing agent, so that the quality is controllable, and the compressive strength of the hat shell and the environmental protection of the process are greatly improved; painting is carried out in an indoor constant-temperature environment, and an air dryer is adopted in the air drying step to simulate a natural air drying effect, so that the defect that the production efficiency is limited due to weather factors in the traditional process is greatly reduced; the bamboo-woven safety helmet manufactured by the process has the advantages of high structural strength, regular and attractive product, high production efficiency, controllable production process quality and high yield.
