Brake Pressure Transducer

Application of tension sensor in textile machine

Rapier looms are one of the shuttleless looms. They are one of the leading models in the development of China's textile machinery industry. They are popular with users for their high speed, width, high quality, and low noise. At present, due to the objective factors such as raw material price increase and RMB appreciation, the originally low profit margins have a difficult living environment and the situation is grim under this background. Therefore, all loom manufacturers and existing users are actively looking for ways to reduce costs. The improvement of the electronic control system will become one of the effective ways.

The tension sensor occupies a relatively important position in the electrical control system of the entire rapier loom. The advantages of the tension sensor produced by our company are reflected in both quality and price. After the market refinement and self-improvement in recent years, we have successfully completed the transformation of the electrical control system for several rapier loom manufacturers and users, helping our customers reduce costs and increase efficiency.

Mounting of Tension Sensors:

The magnetic powder brake is a combination of a transmission unit (input shaft) and a driven unit (output shaft). The space between the two groups of cells is filled with granular magnetic powder (about 40 microns). When the magnetic coil is not conductive, the torque will not be transmitted from the transmission shaft to the driven shaft. However, if the coil is electromagnetically energized, the magnetic powder will be attracted by the magnetic force to cause hardening, and the torque will be transmitted between successive slips. . The principle of magnetic powder brake is similar to magnetic powder clutch, except that the transmission unit is changed into a fixed unit.
The tension control system is composed of magnetic powder brake, proportional amplification, power amplification and tension detection. The system can manually select the pre-tension according to different paper tension requirements, set it to the "auto" position during normal work, and adjust to the pre-tension by "given". The tension adjustment roller is in a balanced state. If the tension changes due to some interference, When the tension adjustment roller is displaced, the tension detector will output a corresponding change signal. After the circuit is amplified, the braking torque of the magnetic powder brake is controlled to change accordingly. The tension changes accordingly, and the tension adjustment roller returns to an equilibrium state, thereby maintaining the tension stability.
