Problems solved by technology

[0004] At present, the JC036-Y111 fiber length analyzer is used to test the evenness of the sliver, but the distance between the front roller and the rear roller is too long, which generates static electricity and the sliver is easy to break due to gravity. Once the sliver breaks during the test , easy to wrap around the lint roll making the test fail

Embodiment 1

[0020] Keep the original equipment state, use the experimental equipment to carry out electrostatic detection, fix the E electrode 1 and electrode 2 on the cotton sliver 4 respectively, which is close to the front roller 1 and the rear roller 2, and the current obtained is about 5-8kv.

Embodiment 2

[0022] The iron metal yarn support plate 5 is selected to carry out jacking contact with the sliver 4. At this time, the E electrode 1 and the electrode 2 are respectively fixed on the sliver 4, that is, near the front roller 1 and the rear roller 2, the obtained The current is about 0.1-0.3kv.

[0023] Example 2

[0024] Select commercial silver-plated iron metal yarn support plate 5 to support and contact the sliver 4. At this time, fix the E electrode 1 and electrode 2 on the sliver 4 respectively, that is, near the front roller 1 and the rear roller 2. , The obtained current is about 0.01kv-0.02kv.

[0025] The above examples prove that the static electricity carried on the cotton sliver 4 can be effectively reduced by using the metal yarn support plate 5 , and the better the conductivity of the metal, the lower the electrostatic charge on the cotton sliver 4 .

Abstract

The invention relates to the technical field of roller type fiber length analyzers, and discloses a device for testing a spinning laboratory, which comprises a front roller, a rear roller, a cotton velvet winding roller, a cotton sliver and a metal yarn supporting plate arranged on the roller type fiber length analyzer. The metal yarn supporting plate is assembled to support the cotton sliver located at one end between the front roller and the rear roller. The device for testing the spinning laboratory has the advantages of being simple in structure, good in using effect and low in cost, effectively solves the problem that cotton slivers are wound around a cotton velvet roller after being broken, greatly improves the operation efficiency of an instrument, and reduces the probability that the cotton slivers are broken and wound to be within 3% from 20%.

Description

technical field [0001] The invention relates to the technical field of a roller-type fiber length analyzer, in particular to a testing device for a spinning laboratory. Background technique [0002] The Roller Length Analyzer is also known as the Zhukov Cotton Fiber Length Meter. Mainly widely used in cotton fiber testing. It is mainly used to calculate: "Cotton fiber body length", "Quality length" base" and other indicators. [0003] When using a roller-type length analyzer for fiber testing, the first step is to use the hand-pulling method to arrange the test sample into a cotton bundle with one end even; the second step is to pinch the neat end of the cotton bundle: clamp the No. 1 clamp The mouth is close to the rear group of restrictors, and the fibers are layered from long to short and arranged on the restrictor fleece, and its neat end should protrude 2mm from the previous group of restrictors. This is repeated twice to form a cotton bundle with a width of 32mm, a ...
