Online spun yarn tension measuring device of ring spinning frame

Abstract

The invention provides an online spun yarn tension measuring device of a ring spinning frame. The online spun yarn tension measuring device comprises a fender beam, a fender body, fender hinges and asensor assembly, the fender beam is arranged in the ring spinning frame, the fender body is fixedly installed on the outer side of the fender beam through the fender hinges, the fender hinges comprisea first hinge and a second hinge, the first hinge is connected to the second hinge through a rotating shaft, the sensor assembly is arranged on the inner side of the fender beam, and a bobbin and a spindle blade are arranged below the fender body; and the fender beam is provided with a beam round hole, the second hinge of the fender hinges is provided with a first hinge long round hole and a second hinge long round hole, the first hinge of the fender hinges is provided with a third hinge long round hole, a contact pin of the sensor assembly is in contact with the first hinge, and transmissionbetween the sensor assembly and the fender body is achieved. According to the online spun yarn tension measuring device, the tension of spun yarn can be detected online in real time in the spun yarndrafting process, and meanwhile the yarn path of spun yarn can be not changed.

Description

technical field [0001] The invention belongs to the field of ring spinning frames, in particular to an online spinning tension measuring device for ring spinning frames. Background technique [0002] When spinning on a ring spinning machine, it is necessary to draft the spun yarn through the differential speed coordination between the front roller, the middle roller and the rear roller to make the spun yarn into a finer spun yarn. During the drafting process, if the tension Excessive assembly will break the spun yarn, which will affect the working efficiency of spinning. Therefore, it is necessary to detect the tension of the spun yarn when drafting the spun yarn to prevent the spun yarn from being broken due to excessive tension. The existing detection device for the spun yarn tension needs The sensor is in contact with the yarn. In this case, the yarn path of the spun yarn will be changed (the yarn path is the path of the spun yarn). The spun yarn tension detection method ...

[0002] When spinning on a ring spinning machine, it is necessary to draft the spun yarn through the differential speed coordination between the front roller, the middle roller and the rear roller to make the spun yarn into a finer spun yarn. During the drafting process, if the tension Excessive assembly will break the spun yarn, which will affect the working efficiency of spinning. Therefore, it is necessary to detect the tension of the spun yarn when drafting the spun yarn to prevent the spun yarn from being broken due to excessive tension. The existing detection device for the spun yarn tension needs The sensor is in contact with the yarn. In this case, the yarn path of the spun yarn will be changed (the yarn path is the path of the spun yarn). The spun yarn tension detection method of changing the yarn path can be used in the laboratory, but in actual production The detection method of changing the yarn path does not meet the international spinning standards, and transactions cannot be carried out if they do not meet the standards; and the existing detection device for detecting the tension of the spun yarn can detect the minimum force far greater than that in the process of spun yarn drafting. The tension generated by the spun yarn, so using the existing tension detection device to detect the tension, the tension of the spun yarn cannot be matched, and the value is very easy to be inaccurate. Therefore, a spun yarn tension detection device is needed, which can be used without changing the yarn path. Sensitive detection of yarn tension
