Bamboo-wood straw and manufacturing method

Abstract

The invention provides a bamboo-wood straw and a manufacturing method. A bamboo-wood straw main body is of a straight-strip tubular structure with a uniform wall thickness, one end of the bamboo-woodstraw main body is cut into a flat cut to serve as a drinking port, the other end of the bamboo-wood straw main body is cut into an inclined cut to serve as a puncturing port, raw materials of the bamboo-wood straw are ripe bamboo or wood which is uniform and consistent in texture, and include sandalwood, beech, oak, phoebe zhennan, ormosia henryi and the like. According to the bamboo-wood straw,a new structure suitable for combination and processing is adopted, requirements for natural formation of the raw materials are small, common materials can be directly adopted, the requirements for selecting materials are small, and the material cost is greatly reduced; the raw materials are environment-friendly, easy to recycle and recyclable, and the bamboo and the wood have the characteristic of environmental protection, and can be conveniently reused in many fields after being used as disposable straws; the processing method is suitable for large-scale production; and the requirements of the raw materials are relatively low, standardized production can be realized, and the quality of products is stable and controllable.

Description

technical field [0001] The invention relates to a straw made of new material used in the catering and retail industry, in particular to a natural and environment-friendly bamboo and wood straw and a manufacturing method thereof. Background technique [0002] Straws are a common daily necessities in daily life. Common straws are processed from high molecular polymers extracted from petroleum. The use of straws is very large, and they are completely disposable consumables. The plastic waste produced 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. In this year, Europe and the United States Some countries have banned the sale and use of plastic straws, and some domestic beverage retail companies have not provided plastic straws, which has caused inconvenience to consumers, so the upgrading of straws is urgent. ...

AI Technical Summary

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
