Description

Technical Field

[0001] The present invention relates to the technical field of yarn feeders, and particularly to an intelligent yarn feeder. Background Art

[0002] When existing yarn feeders transport multiple yarns, they are unable to control the temporarily unused yarns to stop being transported. Single or multiple yarns that have not been used for a long time still follow the yarn feeder and move forward, resulting in the yarns becoming slack and causing the edge frame to alarm or the yarn to be wound (usually when winding the yarn, the yarn storage cylinder will wind dozens of turns), greatly affecting the knitting efficiency or wasting yarn (when winding the yarn). Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an intelligent yarn feeder to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention adopts the following technical solution: An intelligent yarn feeder includes a box body. A yarn clamping device is installed on the box body. A yarn-carrying roller is arranged in front of the yarn clamping device. The yarn-carrying roller is driven to rotate by a motor installed in the box body. The yarn clamping device includes a U-shaped mounting frame body. A plurality of groups of yarn clamping ornament fixing blocks are arranged at the top of the mounting frame body. Each group of yarn clamping ornament fixing blocks includes 2 yarn clamping ornament fixing blocks. A yarn clamping swing rod is rotatably connected between the two yarn clamping ornament fixing blocks. A plurality of electromagnets are fixed to the rear side of the mounting frame body. Each electromagnet corresponds to a yarn clamping swing rod. A plurality of yarn inlet porcelain eyes are arranged at the top of the mounting frame body, and a plurality of yarn outlet porcelain eyes are arranged at the bottom thereof. Each yarn inlet porcelain eye and yarn outlet porcelain eye respectively correspond to a yarn clamping swing rod, and each yarn clamping swing rod corresponds to one path of yarn.

[0005] Further, a yarn clamping ornament baffle is installed at the front end of the bottom of the mounting frame body.

[0006] Further, a stop block is arranged on the side wall of the mounting frame body, and the front side surface of the stop block is a curved surface.

[0007] Further, the stop block is made of one of rubber, polyurethane, nylon, and polytetrafluoroethylene materials.

[0008] Further, the yarn clamping swing rod includes a fixed column. Rotating shafts are respectively connected to both ends of the fixed column. A connecting rod is arranged at the bottom of the fixed column, and a clamping head is fixed to the bottom of the connecting rod.

[0009] Further, the clamping head has a hollow cylindrical structure.

[0010] Further, the clamping head is made of a non-magnetic and magnetically conductive material.

The motor rotates to drive the yarn carrying roller to rotate, so that the yarn is conveyed forward. The tension device detects the tension of the yarn conveyance and transmits the tension data to the control chip provided on the control circuit board to understand the usage of the yarn of this route. When the yarn tension is abnormal, the control chip controls the electromagnet to work. Under the action of the electromagnet, the yarn clamping piece swings towards the stopper side and fits with the curved surface of the stopper to form a certain clamping force. The yarn is clamped between the clamping head and the stopper, so as to realize the clamping of the yarn at the yarn inlet end through control to control the conveyance of the yarn, avoid false alarms or yarn entanglement of the edge frame caused by excessive yarn conveyance, improve the knitting efficiency and reduce the waste of yarn.
