Abstract

The invention provides a tension control device, which includes a pulley passing through a belt, a rotating shaft for fixing the pulley, a length measuring device and a resistance device, and both the length measuring device and the resistance device are connected with the electrical equipment of the equipment. The control box is connected, and the outer edge surface of the belt pulley in contact with the belt is a knurled surface. In the invention, the length measurement device is driven by the rotation of the pulley to measure the length, and the measured signal is transmitted to the electrical control box. The requirements for the tension of the strips at different length stages of the strips, so as to achieve the tightness required by the coiling process.

Description

technical field [0001] The invention relates to the field of belt transmission, in particular to a tension control device. Background technique [0002] The tape winding machine used in the current tape production process does not consider the tension problem of the tape during the tape winding process, but simply winds the tape on the reel. In this way, the inner and outer layers of the tape rolled out have the same degree of tightness, which makes the dyeing uneven in the subsequent dyeing process, and the dyeing effect is greatly reduced. Contents of the invention [0003] The present invention proposes a tension control device, which can make ribbons in different length regions reach different tension states, and realize the tightness required by the coiling process of the yarn bobbin. [0004] The technical solution of the present invention is achieved in the following way: a tension control device includes a pulley passing through the belt, and a rotating shaft that...
