Abstract

The invention provides a straw, a mold for manufacturing the straw and a manufacturing method of the straw. The manufacturing method of the straw comprises the following steps that S1, a layer of cuboid-shaped wood veneer or bamboo veneer is sliced from a log or plate-shaped bamboo board; S2, a boundary line is drawn in the direction parallel to the long edge of the wood veneer or the bamboo veneer; S3, a viscous material is sprayed on the upper surface of a second section; S4, the wood veneer or the bamboo veneer is rolled into a long cylinder shape from the long edge position of the first section around an inner shaping mold; S5, the inner shaping mold and the wood veneer or bamboo veneer rolled into the long cylinder shape on the inner shaping mold are inserted into an outer shaping mold together; S6, the inner shaping mold and the shaped long cylindrical wood veneer or bamboo veneer on the inner shaping mold are moved out of the outer shaping mold together; and S7, the shaped long cylindrical wood veneer or bamboo veneer is taken out of the inner shaping mold. The straw provided by the invention has no peculiar smell, and is not easy to soften, deform and crack.

Description

technical field [0001] The invention relates to the technical field of straws, in particular to a straw, a mold for making the straw and a method for making the straw. Background technique [0002] As people pay more attention to the ecological environment, the use of non-degradable disposable plastic straws has been banned, and the market demand for paper, bamboo wood or biodegradable plastic straws is increasing. At present, the most mainstream is the multi-layer kraft paper straw. The production process of this straw is to tightly wind and rotate multi-layer long paper strips around the middle round rod to form a cylindrical shape with oblique thread-like seams and a flat surface. straws. The advantage of kraft paper straws is that it takes advantage of kraft paper's good toughness, short fibers, short rigidity, low rigidity and easy bending. The production speed is fast and the cost is low. Straws with different diameters and layers can be made according to requirements...
