Description

Technical Field

[0001] This utility model relates to the field of mask ear loop technology, specifically to an automatic tension adjustment mechanism for mask ear loop feeding. Background Technology

[0002] Ear loops are a type of mask accessory used for hanging on the ears. During mask production, the ear loops are ejected from the cardboard box and guided into the mask production equipment for sewing. During the conveying process, the ear loops are relatively loose and elastic, making them prone to twisting. Therefore, they need to be tensioned to a certain degree before being conveyed into the mask production equipment to ensure stable conveying. To address this, we provide an automatic tension adjustment mechanism for mask ear loop feeding. Utility Model Content

[0003] The purpose of this invention is to provide an automatic tension adjustment mechanism for mask ear loop feeding, which solves the problem of loose ear loops that need to be tightened during the mask ear loop feeding and conveying process.

The wheel adjustment mechanism includes a drive wheel, a left clamping wheel, a right clamping wheel, and a movable pulley. The drive wheel, left clamping wheel, and right clamping wheel are arranged parallel to each other at the same height. The drive wheel is located between the left clamping wheel and the right clamping wheel. The drive wheel is connected by a connecting... A fixed drive motor on the frame drives the rotation. The circumference of the drive wheel and the circumference of the left and right clamping wheels form a clamping surface. The movable pulley is vertically movable and parallel to the drive wheel directly below it. The ear loop rope passes around the guide rod and sequentially through the input limit ring and the limit seat. The ear loop rope output from the limit seat passes through the clamping surfaces of the drive wheel and the left clamping wheel and wraps around the movable pulley. The ear loop rope output from the movable pulley passes through the clamping surfaces of the drive wheel and the right clamping wheel and passes through the output limit ring.
