Tension sensor for liquid ammonia mercerizing machine

Abstract

The invention discloses a tension sensor for a liquid ammonia mercerizing machine, belongs to the field of textile industry, and particularly relates to a liquid ammonia mercerizing machine. The invention provides a special tension sensor for a liquid ammonia mercerizing machine, which has good contact and accurate data transmission. The technical scheme is that the tension sensor for the liquid ammonia mercerizing machine is arranged between a driving wheel and a driven wheel in the liquid ammonia mercerizing machine and comprises an idler wheel, a strain gauge and a signal connector; the idle wheel is arranged between the driving wheel and the driven wheel, two ends of the idle wheel are connected with a liquid ammonia mercerizing machine bracket through a bearing, the idle wheel is of ahollow tubular structure, a plurality of strain gauges are fixed on the surface layer of the idle wheel, the plurality of strain gauges are electrically connected with the signal connector, and the signal connector is arranged at one end of the idle wheel, the signal connector comprises a fixing block, a middle connecting block and a lead wire end head, the fixing block, the middle connecting block and the lead wire end head are sequentially arranged from one end of the idler wheel to the outer side of the idler wheel, and the middle connecting block and the lead wire end head are contacted and rotate along with each other.

Description

technical field [0001] The invention discloses a tension sensor for a liquid ammonia mercerizing machine, which belongs to the field of textile industry, and in particular relates to a liquid ammonia mercerizing machine. Background technique [0002] Mercerizing machine is an essential and important equipment in the pre-treatment process of cotton fabrics and other printing and dyeing. The mercerizing machine is mainly composed of a cloth feeding frame, an alkali soaking tank, a ventilation device, an expanding device, a washing device and a washing tank, etc. Mercerizing refers to the process in which the fabric is treated with concentrated caustic soda or other mercerizing agents under a certain tension to improve the fiber properties and make it have the same luster as real silk. Generally speaking, within a certain range of fabric mercerizing, the magnitude of the tension is directly proportional to the resulting luster. On the contrary, excessive tension will have a ve...

Problems solved by technology

At this time, the strain gauge and the fixed interface rotate relatively. After a long time, the contact between the strain gauge and the fixed interface is poor, resulting in errors in the measurement signal received by the tension controller, which further affects the quality of fabric processing.
