Description

Technical Field

[0001] This utility model relates to the field of electromagnetic tensioner technology, specifically to an electromagnetic tensioner with a yarn guiding mechanism. Background Technology

[0002] An electromagnetic tensioner is a tensioning device that uses electromagnetic force to provide resistance. It is widely used in the textile industry. During the processing of yarn and ribbon, the electromagnetic tensioner can provide tension to the yarn and ribbon during transport. However, existing tensioners only guide the transported yarn and ribbon through feed and discharge rollers, making it easy for the yarn and ribbon to slip off the rollers during transport, leading to tensioner failure. Therefore, improvements to the existing technology are needed. Utility Model Content

Furthermore, the guide plate can limit the movement of the yarn and prevent it from slipping off the roller.

[0013] 2. This utility model adds a positive and negative screw, an internal threaded tube, and a guide frame to the adjustment frame. When guiding the yarn, the moving plate can be moved inside the adjustment frame by the threaded engagement between the positive and negative screw and the internal threaded tube. This allows the distance between the two guide plates to be adjusted according to the width of the yarn. Attached Figure Description
