Description

TECHNICAL FIELD

[0001] The utility model belongs to the yarn sizing machine technical field, concretely relates to a sizing trough tension control device of yarn sizing machine. BACKGROUND

[0002] The yarn sizing machine is the equipment of warp yarn processing, and is a mechanical device for sizing, drying and winding warp yarn into a sizing shaft. The sizing trough tension control device is installed on the yarn sizing machine to ensure that the warp yarn maintains appropriate tension in the sizing trough, thereby smoothly realizing qualified sizing. Appropriate tension helps the warp yarn to better soak sizing liquid, makes the sizing liquid uniformly distributed on the warp yarn, and improves the sizing quality. The sizing trough tension control device of the yarn sizing machine is generally driven by a motor. The motor drives the rotation of the pay-off reel. In addition, the rotation of the tension roller and the lead roller corresponding to different motors is driven. When the warp yarn is conveyed, the tension sensor senses the tension of the tension roller. When the tension is large, the tension sensor sends a signal to the tension controller, and then sends a signal to the motor. The motor controls and reduces the speed of the tension roller and the lead roller. By changing the speed difference of the tension roller and the lead roller, the tension of the yarn is adjusted. When the tension is small, the tension sensor sends a signal to the tension controller, and then sends a signal to the motor. The motor controls and increases the speed of the tension roller and the lead roller. The speed difference of the tension roller and the lead roller is changed to adjust the tension.

[0003] The sizing trough tension control device of the yarn sizing machine controls the tension by controlling the speed of the motor, i.e. controlling the speed of the tension roller and the lead roller. In this method, the speed of the tension roller and the lead roller needs to be frequently changed. The shafts of the tension roller and the lead roller are accelerated to wear under the condition of frequent changes, thereby affecting the speed adjustment. When the speed of the tension roller and the lead roller deviates, the change of the tension will be affected, thereby causing wear to the warp yarn. In the long-term use process, the speed control of the tension roller and the lead roller cannot be achieved, the tension control of the warp yarn cannot be satisfied, stable sizing cannot be realized, and the tension control of the warp yarn cannot be realized under the condition that the speed of the tension roller and the lead roller is stable.

[0004] The existing sizing trough tension control device of the yarn sizing machine cannot realize the tension control of the warp yarn under the condition that the speed of the tension roller and the lead roller is stable. Therefore, the present application provides a sizing trough tension control device of a yarn sizing machine. UTILITY MODEL CONTENTS
