Embodiment Construction

[0023] The present invention will be described in further detail below through embodiments in conjunction with the accompanying drawings.

[0024] Such as figure 1 , figure 2 and image 3 Shown, the comber noil rate test method provided by the present invention is to measure the lap weight G of the comber and the combed sliver weight g of the comber output in the measurement unit time, and calculate the combed according to the following formula Machine noil rate η (%):

[0025]

[0026] In this embodiment, since the combing machine is provided with 8 lap rollers, and there is 1 lap above each lap roller, each lap is weighed twice, and the time interval between the two weighings is 3 minutes; let G 1i , G 2i Respectively, the weight of the i-th cotton lap (i=1,2,3...8) when the cotton lap is weighed for the first time and the second time, g 1 、g 2 are the weights of the sliver cans when they are weighed for the first time and the second time respectively, then the ab...

Abstract

The invention relates to a measurement method and a measurement device for the waste percentage of a combing machine. The measurement method comprises the following steps of: measuring a weight G of laps fed into the combing machine and a weight g of combed laps output by the combining machine in unit time; and calculating the waste percentage eta (percent) of the combing machine according to the following formula. The invention also provides the measurement device for the waste percentage of the combing machine, which comprises a control device, a signal processing device, a lap weighing mechanism and a sliver can weighing mechanism. The lap weighing mechanism comprises a lap tray, a lap weighing sensor and a lap tray lifting mechanism. The sliver can weighing mechanism comprises a sliver can rotating mechanism, a lifting disk, a sliver can weighing sensor and a disk lifting mechanism. In the invention, a method of weighing the laps and a silver can on line is adopted; the waste percentage is calculated to be obtained by the control device; and the measured combing waste percentage is accurate; the harmful effect on the operation and the spinning quality of the combing machine cannot be generated in the whole measuring process; and in the measuring process, return slivers and return laps cannot be generated, so the measurement method and the measurement device are beneficial for improving the production efficiency.

Description

technical field [0001] The invention relates to the field of textiles, in particular to cotton spinning combing technology, in particular to a test method and a test device for the noil rate of a comber. Background technique [0002] The combing noil rate refers to the percentage of the ratio of the noil amount to the feeding amount per unit time in the production process of the combing machine. The comber noil rate not only affects the yarn quality, but also affects the spinning cost. [0003] The existing method for measuring the noil rate of combing is: stop the comber after running for 15s-30s, measure the noil amount of the comber and the weight of the spun combed sliver, and calculate the noil of the comber with formula (1) Rate: [0004] (1) [0005] In the formula, η is the noil rate of the comber, g is the weight of the combed sliver, and g1 is the noil amount of the comber. There are following problems with this measurement and calculatio...
