Full-automatic bamboo straw sorting device and sorting method thereof

Abstract

The invention provides a full-automatic bamboo straw sorting device and a sorting method thereof, and relates to the field of bamboo straws. The full-automatic bamboo straw sorting device comprises a conveying mechanism; an air tightness detection mechanism, a uniformity detection mechanism and an inner wall detection mechanism are sequentially arranged on the conveying mechanism; the conveying mechanism comprises a conveying frame; the air tightness detection mechanism comprises first supporting plates fixed to the two sides of the conveying frame correspondingly; an air inflation pipe is slidably connected to the first supporting plate on one side; a sealing pipe is slidably connected to the first supporting plate on the other side of the conveying frame; the air inflation pipe is pneumatically connected with an air supply and exhaust mechanism; and a sorting wheel is rotationally connected between the first supporting plates on the two sides. The air tightness, the uniformity and the inner wall of a bamboo straw are detected in sequence, the air tightness of the bamboo straw can be detected, meanwhile, the pressure resistance of the bamboo straw under a certain pressure difference can be detected by controlling the amount of filled or pumped air, and then high-quality bamboo straws are detected and screened out through the uniformity detection mechanism and the inner wall detection mechanism.

Description

technical field [0001] The invention relates to the field of bamboo straws, in particular to an automatic sorting device for bamboo straws and a sorting method thereof. Background technique [0002] Most of the existing straws are plastic straws, but due to the low recycling rate of plastic straws, it causes environmental pollution. The paper straws that replace them are not resistant to soaking and are easy to deform after soaking in beverages. Bamboo straws are made of natural bamboo and are environmentally friendly. , Strong anti-deformation ability, the preparation of bamboo straws is formed by cutting natural bamboo and surface treatment. Before the bamboo straws leave the factory, they need to go through category screening to eliminate low-quality straws. [0003] For example, the patent No. CN112518930A discloses a bamboo straw processing method, comprising the following steps: two or more pieces of bamboo are connected to form a bamboo belt, the bamboo belt is contin...

AI Technical Summary

Problems solved by technology

[0004] However, due to uncontrollable factors in the bamboo processing process, there are still inferior products in the processed bamboo straws, such as the damage of the surface of the straws leading to the poor airtightness of the bamboo straws, which affects the use, so there is a need for a product selection process, the prior art There is no relevant equipment for quality screening of bamboo straws
