Technical Field

[0001] The present application relates to the technical field of straw processing equipment, and in particular to a bending equipment for straw processing. Background Art

[0002] Corrugated straws are straws whose main structure is corrugated except for the head and tail. When corrugated straws are first produced, the entire straw is a straight tube. Before packaging, the corrugated straws need to be bent at the corrugated section to form a curved tube. At present, the bending process of corrugated straws is done manually. When bending straws manually, it is difficult to make the bending part of the straw consistent. The height of the curved tubes after bending varies greatly, which affects the uniformity and aesthetics of the product.

[0003] In the prior art, a utility model patent with patent number CN201620707189.2 discloses a corrugated straw bending machine, which drives the clamping plate to clamp and rotate the bending part of the straw through relative movement and rotation between the upper shell and the lower shell to form a bend. However, it can only bend straws of a single specification and is not applicable to straws with bending parts of different lengths. Utility Model Content
