Problems solved by technology

[0005] The current dead zone values ​​are all calculated based on mechanical results, and then directly input the value into the system. In the actual operation process, a certain adjustment is made according to the CV value. This adjustment is relatively extensive and has a lot to do with cotton The relationship cannot be adjusted intuitively
[0006] In the actual leveling process, the fluctuation of the thickness of the incoming cotton sliver is not large, and it is difficult to make a clear comparison with the fluctuation of the outgoing cotton sliver

Embodiment Construction

[0028] Such as figure 1 As shown, the accurate measurement system for the uniform dead zone of the draw frame includes a cotton-feeding introduction device 7, a cotton-feeding cutting device, a detection device 11, and a thickness measuring device 6, and the detection device 11 and the cotton-feeding cutting device and the thickness measuring device 6 are respectively The cotton input device 7 is connected with the cotton input cutting device, and the cotton input cutting device is located at the front end of the cotton input inlet of the draw frame 4 . The front end of the incoming cotton inlet of the draw frame is equipped with a leveling control system, which is used to record the thickness of the incoming cotton sliver. The leveling control system is also connected with the detection device.

[0029] The described cotton-feeding introduction device 7 is positioned at the can place device 1, and a plurality of cans 2 are placed on the can place device 1. In the present emb...

Abstract

The invention provides a drawing leveling dead space accurate measurement system and measurement method. Mutation fluctuations of input cotton slivers are made and then thickness data of the output cotton slivers is recorded, so that an accurate value of a dead space is determined by viewing a thickness waveform. According to the drawing leveling dead space accurate measurement system and measurement method, a length of the dead space can be conveniently and efficiently determined, and the best leveling effect can be achieved under the same technical conditions. Quality of the cotton slivers is improved.

Description

technical field [0001] The invention relates to a system and method for accurately measuring the dead zone length in drawing frame levelling, in particular to an accurate measuring system and method for drawing frame levelling dead zone length. Background technique [0002] The function of the drawing frame is to improve the internal structure of the sliver, so as to improve the uniformity of its long segments, reduce the unevenness of the weight at the same time, make the fibers in the sliver straight and parallel, reduce the hooks, make the fineness meet the requirements, and make different types or Raw materials of different qualities are mixed evenly to achieve the specified mixing ratio. According to the form of drafting mechanism, the drawing frame is divided into two categories: roller drafting drawing frame and needle carding machine. [0003] The sliver of the drawing frame comes from the combing machine. The sliver produced by the combing machine is put into the e...
