[0002] A bending device for straws is a mechanical device specially designed to bend straight straws into a specific shape. This device plays an important role in the straw manufacturing process and is mainly used to improve the convenience of straw use, optimize storage and transportation, and enhance functionality.

[0003] In the prior art, a bending track is usually provided at the upper end of a fixed frame, a conveying member is provided inside the fixed frame, a bending column is provided at the upper end of the conveying member, the bending column is inserted into the bending track, and a feeding member is provided at the upper end of the fixed frame, so that the straws can be bent under the action of the bending column and the bending track. However, in this method, when the straws fall from the feeding member, the two ends of the straws are not positioned by the positioning assembly, but are directly brought into the bending track for bending by the bending column. The falling straws may deviate from the landing point due to factors such as gravity or airflow. Different falling positions may cause the bending position to deviate from the preset value, thereby making the bending position of the straws inconsistent, affecting the overall quality and consistency of the product.
