In an alternative embodiment, the helical direction of the bamboo strip is in the same direction as the fibre direction of the bamboo tube.
In an optional embodiment, the contact surfaces of two adjacent bamboo tubes are provided with composite material layers, and the surfaces of the composite material layers are provided with glue layers.
In an alternative embodiment, the helical angle of the bamboo strip is in the range of 5 ° to 65 °.
In an alternative embodiment, the wall thickness of the bamboo tube ranges from 0.1mm to 0.5 mm.
The beneficial effects of the utility model reside in that: the utility model provides a bamboo straw has strengthened the structural strength of bamboo straw including the thick bamboo tube more than two-layer, and every layer of thick bamboo tube adopts the spiral coiling structure, has promoted the toughness and the anti performance of buckling of bamboo straw to, set up the spiral seam of adjacent two-layer thick bamboo tube into the dislocation form, utilize the seam that is in the bamboo area of outer bamboo strip will be in the seam cover of the bamboo area of inlayer, with the roughness that has promoted bamboo straw product leakproofness and appearance, improved the aesthetic property of bamboo straw body.

Detailed Description
In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
Referring to fig. 1 and 2, the bamboo straw of the present invention comprises more than two layers of bamboo tubes, each layer of bamboo tube is formed by continuous spiral winding of bamboo strips, and the spiral seams of two adjacent layers of bamboo tubes are arranged in a staggered manner.
From the above description, the beneficial effects of the present invention are: the utility model provides a bamboo straw has strengthened the structural strength of bamboo straw including the thick bamboo tube more than two-layer, and every layer of thick bamboo tube adopts the spiral coiling structure, has promoted the toughness and the anti performance of buckling of bamboo straw to, set up the spiral seam of adjacent two-layer thick bamboo tube into the dislocation form, utilize the seam that is in the bamboo area of outer bamboo strip will be in the seam cover of the bamboo area of inlayer, with the roughness that has promoted bamboo straw product leakproofness and appearance, improved the aesthetic property of bamboo straw body.
Furthermore, the spiral direction of the bamboo strip is the same as the fiber direction of the bamboo tube.
From the above description, the bamboo strip is spirally wound along the preset spiral angle in the fiber direction (stem direction), so that the winding difficulty can be reduced, the mechanical property of the wound cylinder is ensured, cracking is prevented, cutting is facilitated, the product quality of the bamboo straw is improved, the risk of bulging and tilting of bamboo skins can be reduced, and the flatness of the body of the bamboo straw is ensured.
Furthermore, the contact surfaces of the two adjacent layers of the bamboo tubes are provided with composite material layers, and the surfaces of the composite material layers are provided with glue layers.
From the above description, the surface to be glued of each layer of bamboo tube is determined according to the number of the superimposed layers, the composite material layer is glued and bonded on the surface to be glued of the bamboo tube, when single-sided or double-sided gluing is performed on the surface of the bamboo strip, glue is uniformly coated on the composite material layer, and the gluing amount is automatically adjusted according to the glue property. The composite material layer mainly plays a role in improving the adhesive firmness and enhancing the mechanical property of the processed bamboo straw. The glue film plays the effect that improves connection structure's stability between the thick bamboo tube, then dries in order to improve the sticky effect of glue.
Further, the spiral angle of the bamboo strip ranges from 5 degrees to 65 degrees.
From the above description, it can be seen that through repeated tests, the quality of the bamboo straw obtained by winding the bamboo strips within the above spiral angle range is optimal.
