Abstract

The invention relates to a device for measuring air flow parameters in a main carding area of a carding machine. The device comprises a conveying main pipeline and probes; the conveying main pipeline is in an L shape, one end of the conveying main pipeline serves as a main pipeline outlet, the other end of the conveying main pipeline serves as a plurality of the vertically-arranged probes, the head of each probe is provided with a static-pressure pressure tapping hole and a full-pressure pressure tapping hole, the static-pressure pressure tapping holes are formed in the back faces of the full-pressure pressure tapping holes, a static-pressure branch pipe and a dynamic-pressure branch pipe are arranged in each probe, the static-pressure pressure tapping holes and the full-pressure pressure tapping holes are connected with the static-pressure branch pipes and the dynamic-pressure branch pipes which are arranged in the probes respectively, and the tail ends of the static-pressure branch pipes and the tail ends of the dynamic-pressure branch pipes are connected with a micro-pressure sensor through the main pipeline outlet; the two probes close to the bent portion of the conveying main pipeline are each sleeved with a steel sleeve, the two steel sleeves are connected through a steel segment, the upper end of the steel segment is provided with an electric resistance wire, one of the steel sleeves is connected with a conductive bar, and the other end of the conductive bar is installed at the upper end of the steel segment. According to the device, the position parameters of the probe depth are obtained through current transformation, so that experiment measuring is accurate and rapid.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a device for testing airflow parameters in a main comb area of ​​a carding machine and a testing method thereof. Background technique [0002] Carding machine is used to process cotton fiber and chemical fiber, which belongs to textile machinery. According to the spinning process, carding is an important process. The front process of the carding machine is the combined opening and cleaning machine, and the subsequent process is the drawing frame (carding process) or sliver coiler (combing process). [0003] The working principle of the carding machine is to loosen, card and remove impurities from the cotton (fiber) rolls sent by the previous process or the oil cotton (chemical fiber) layer supplied by the cotton box, so that all the coiled cotton loops become The single fiber can be basically straightened, and in this process, the broken seeds, impurities and short fibers left...
