Electromagnetic yarn balance roller

Abstract

The invention relates to an electromagnetic yarn balance roller which comprises a roller shell, and an electric core and a built-in circuit which are embedded inside the roller shell. The roller shell is coaxial with the electric core. The electromagnetic yarn balance roller is characterized in that the outer layer and the inner layer of the electric core are respectively a magnet group and a coil, a central shaft is fixedly mounted at the axis of the coil, one free end of the central shaft extends out of the roller shell, and the electric core is electrically connected with the built-in circuit. The electromagnetic yarn balance roller has the advantages that defects in the prior art are overcome, yarn tension can be changed instantly by using motor principles, the brake force of the roller is controlled by the electric core embedded inside the roller shell, the faster the yarn moves, the larger the brake force of the roller is, the slower the yarn moves, the smaller the brake force of the roller is, yarn tension fluctuation can be lowered, and high automation level, flexible reaction, instantaneity and quickness are achieved.

Description

technical field [0001] The invention relates to a spinning equipment accessory, in particular to an electromagnetic yarn balancing roller. Background technique [0002] The yarn is usually wound or unwound at high speed on the winder and doubling machine. The movement of the yarn is caused by the intertwining of the yarn on the unwinding drum and the friction between the parts and the yarn on the machine. The moving yarn will have unstable yarn tension, even yarn running stuttering and yarn breakage. At the same time, it will also affect the shaping of the yarn package. In order to ease the yarn tension, make it run smoothly and reduce tension The amplitude of the fluctuation requires adding a yarn balance roller between the unwinding package and the forming package, so that the yarn can be wound smoothly, reducing yarn breakage and improving the forming quality. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides an e...
