Device for measuring volume change of at least one textile fiber band

Abstract

The invention relates to a device for measuring volume change of one or a plurality of textile fiber bands, which comprises a first movable wheel and a second fixed wheel, wherein the wheel shafts of the first movable wheel and the second fixed wheel are parallel, and the wheel center distance between the first movable wheel and the second fixed wheel can be changed. At least one textile fiber band is pulled between the first movable wheel and the second fixed wheel in a sliding mode. A circumferential ring of the first movable wheel is matched in an annular groove, wherein the annular groove is arranged at the outer rim of the second fixed wheel, and the shape of the annular groove corresponds to that of the circumferential ring. The first movable wheel and the second fixed wheel are pressed together by an elastic device to enable the first movable wheel to move away from or move to the second fixed wheel according to the instant section of at least one band. The band is pressed in the groove of the second fixed wheel by the circumferential ring of the first movable wheel, and the first movable wheel is connected to a measuring device, wherein the second fixed wheel is pivoted on a supporting member which is integrated with an equipment stand of an installation device; the first movable wheel is supported by an eccentric element and is pivoted to the eccentric element; the eccentric element is pivoted on the supporting member; and a rotating shaft line of the eccentric element is parallel but not coincident with a shaft line of the first movable wheel.

Description

technical field [0001] The present invention relates to a device for measuring the volume change of at least one textile fiber ribbon, in particular a device for drawing frames, cards, combers and the like. Background technique [0002] Textile fibers can be natural like cotton and other natural fibers, or synthetic. [0003] Currently so-called "tongue and groove" devices are used for quality monitoring and automatic adjustment of textile industry equipment such as draw frames, cards, combers, etc. [0004] Such devices generally comprise two wheels with parallel axles of variable track distance between which at least one textile fibre band is slidably drawn. [0005] The first wheel of the two wheels is fitted in the annular groove of the second wheel with its circumferential ring. The annular groove is opened at the outer rim of the second wheel and has a shape corresponding to the circumferential ring. [0006] The two wheels are pressed against each other by elastic m...

[0015] This conversion inevitably results in a slight loss of precision

[0016] However, since analog sensors show different readings depending on the air conditioning in the building, even regardless of the geographic area of ​​the building in which the device is placed, this reduction in accuracy must be compared to the fact that analog sensors are often subjected to environmental conditions such as temperature and humidity.
