Experimental investigation of the relationship between raw shaft density and saw cylinder electric motor load current

The article deals with the physical and mechanical aspects of the transportation of raw cotton in a pneumatic transport system. During transportation the raw cotton collides with the working surfaces of the outlets of the pipelines and the front body of the separator at various angles. A theoretical analysis of the influence of the angle of impact on the degree of damage to raw cotton in the pneumatic transport system was performed. Based on the constructed model of physical and mechanical interaction and the use of an experimental setup an increase in the speed of pneumatic transport of raw cotton, an increase in seed damage, a deterioration in the quality of cotton fibers, and a decrease in their germination during the preparation of raw cotton were studied.

et al. 2024

The purpose of this paper is to increase the service life of the brushes in the interaction of the puller brushes and the drum when cleaning cotton from large debris during the cotton removal process. The authors conducted an experimental study to determine the actual value of the number of impacts (touches) of the puller brushes on the surface of the saw drum. The angle of rotation of the serrated drum around its axis during the period of influence of the puller brushes on it was determined. The paper also describes determination of the average number of blows (touches) of the puller brushes on the saw drum.

“…Figure 5 shows the gradient of yarn unevenness of 25 tex, figure 6 shows the gradient of yarn unevenness of 11.7 tex, figure 7 shows the gradient of yarn unevenness of 10 tex along 3 cm segments. The analysis of the experimental results shows that the installation of a double pressure roller on the exhaust cylinder reduces the unevenness of yarn by 11% when producing yarn of 25 tex, by 4.8% when producing yarn of 11.7 tex and by 8.8% when producing yarn of 10 tex [10][11][12]. roving, 666.6 tex.…”

Analysis and computational research of line parameters of the spinning line of ring spinning machines

The main task of the technological process in existing spinning systems in the processing of natural, artificial and synthetic fibers into yarn is to obtain a ribbon, rovings and yarn uniform in structure and properties by folding and drawing. The article studies analytical dependences for calculating the angle of flow around the exhaust cylinder by the lobe on the spinning line of ring spinning machines. Analysis of the results of the experiment allows us to conclude that ensuring a constant clamping of the straps in the exhaust zone reduces the unevenness of the product during stretching.
