A kind of bamboo and wood straw and its manufacturing method

Abstract

The present invention proposes a bamboo and wood straw and its manufacturing method. The main body of the bamboo and wood straw is a straight tubular structure with uniform wall thickness. The raw material of the straw is mature bamboo or wood with uniform texture, which can be sandalwood, beech, oak, nanmu, rosewood and so on. Bamboo wood straw adopts a new structure suitable for combination and processing, which requires less natural formation of raw materials, can directly use common materials, has less requirements for material selection, and greatly reduces material costs. The raw materials are environmentally friendly, easy to recycle, and can be reused; bamboo and wood materials are environmentally friendly, and they can be reused in many fields after being used as disposable straws. The processing method is suitable for large-scale production; the requirements for raw materials are relatively low, standardized production is possible, and the quality of the product is stable and controllable.

Description

technical field [0001] The invention relates to a new material straw used in the catering retail industry, in particular to a natural and environmentally friendly bamboo and wood straw and a manufacturing method thereof. Background technique [0002] Straw is a common daily necessities in daily life. Common straws are processed from high molecular polymers extracted from petroleum. The usage of straws is very large, and they are completely disposable consumables. The plastic waste generated by waste products is a non-degradable material. Even if it is recycled, it will inevitably produce secondary pollution in the process of production and processing, and even direct combustion will release harmful gases. Some countries have banned the sales and use of plastic straws, and some domestic beverage retail companies have not provided plastic straws, causing inconvenience to consumers. Therefore, the upgrading of straws is urgent. [0003] In order to improve the pollution proble...

Problems solved by technology

[0004] In the existing technology, it has been proposed to use the hollow structure of natural bamboo to form a through bamboo tube after the bamboo joints are opened to use as a straw, such as the natural bamboo straw proposed in CN202891467U, and the new straw proposed in CN204292817U. The natural bamboo tube structure has high requirements on the selection of materials. It is necessary to carefully select new and tender bamboo with an appropriate outer diameter. The selection is difficult, and the naturally grown bamboo has a natural curvature. It is very difficult to open the bamboo joints, the distance between the bamboo joints is uneven, the shape of the processed bamboo is various, and the most important point is that the young and tender bamboo is not fully grown, and the gaps between the fiber structures are large. The water content in the cell wall is high, it is easy to grow insects and mildew, and it is not easy to transport and store. The above shortcomings of using natural bamboo tube structure prove that this method cannot be used for large-scale production to replace the existing plastic straws. The application prospects of natural bamboo tubes are insufficient. , it is necessary to abandon the use of natural structures, and propose new straw structures and straw processing methods that can be applied to large-scale production
