Rolling type bamboo straw and processing technology and processing device thereof

Abstract

The invention discloses a rolling type bamboo straw and a processing technology and a processing device thereof, and belongs to the technical field of straw production. The bamboo straw is a cylindrical tube formed by rolling thin bamboo sheets soaked and softened in water or wood slices coated with glue in a spiral manner. The processing technology comprises the steps that after bamboo and wood raw materials are cut off and dried in the process, softening treatment is carried out, then the bamboo and wood raw materials are cut into slices, and the slices are rolled and formed by equipment; rolling equipment adopted in the process can realize the rolling of thin sheets and cutting of redundant thin sheets on the inner layer and the outer layer at the same time, and the rolling type bamboostraw is automatically separated after being formed, so that the production efficiency of the rolling type bamboo straw can be greatly improved. Compared with a traditional drilling type bamboo straw,the rolling type bamboo straw has the advantages that the outer wall of the bamboo straw is thinner, the length of the bamboo straw can be longer, and the raw materials are saved.

Description

technical field [0001] The invention belongs to the technical field of bamboo and wood straw production, in particular to a rolled bamboo and wood straw and its processing technology and processing device. Background technique [0002] Most of the straws used in the current food market are plastic straws, which have disadvantages such as poor high temperature resistance, poor degradation, non-environmental protection, and short service life, and related chemical substances need to be used in the manufacturing process. Ecological environmental protection and ecological cycle have a very large degree of harm. With the progress of social development, human beings are becoming more and more aware of the protection of the ecological environment. At present, most countries in the world have implemented or plan to implement the "plastic ban", and plastic straws will soon be eliminated from the market. [0003] At present, bamboo tubes or wooden tubes have begun to appear in foreig...

Problems solved by technology

This processing method is the most simple and direct, but it also has relatively large defects. When the pipe hole of the straw is small and the straw is long, the drill bit is required to be very slender, so that the drill bit is easy to bend and deform when drilling. In the end, the shape of the processed pipe hole is poor, and the drill bit breakage rate is high, which not only reduces the production efficiency, but also increases the maintenance cost. Therefore, this traditional processing method cannot process the straw or the length of the fine hole. Very long straws, at the same time, due to the poor forming degree of the tube holes, the thickness of the processed straw tubes is uneven, and because the tube holes are in a hollow state when the outer wall of the tube is processed, the straws are easy to be squeezed and broken, resulting in product scrapping, so This traditional processing method has high requirements on the thickness of the tube wall and is not suitable for the production of thin-walled straws.
