Check whether the roller transmission gear and shaft and key pin are loose and doze and wear. The short pile and fiber accumulate in the round sealing plate at the bottom of the top winding device. Cleaning and combing cause more fiber damage, resulting in high sliver short-pile growth rate; poor fiber separation and orientation in the sliver, bundle fibers and chaotic fibers; 3. The fine, combined, and coarse up and down cleaning devices are not effective, resulting in the accumulation of velvet belts and piles on the pile board into the sliver; 8. Answer: The roving spitting head has the following reasons: 1.
The fibers on the velvet Draw Texturing Yarns factory on the drape are scraped into a pile of velvet and brought into the drafting zone by the velvet cover And dropped onto the drafting bar; the lower cleaning apron is damaged and the hanging flower is brought into the sliver by the lower roller; 3. The roving roller head has vibration: the roller drive shaft (roller synchronous belt wheel shaft), the roller head section, and the roller head section have different axes;
the internal key of the coupling between the roller drive shaft and the roller head section and The key groove is worn out; the roller bearing at the connection between the roller head and the roller head is worn or knocked; the bearing in the bearing housing of the roller drive shaft is damaged; 2. The draw bar and roller sticky flower are attached to the sliver; 6. Due to unreasonable process design such as roving roller gauge, jaw distance, top roller pressure, draft distribution, etc. 58.
The channels of combing, finishing, merging, thick beard and yarn are not smooth, causing sticking, Hanging, winding, accumulating, and belting; 7. When the feeding is biased, the output is biased when the leveling is turned on, indicating that the leveling strength is weak. The 61a version of HSD961AL, the adjustment rate formula (taking 8 feed bars as an example): the current adjustment rate (set to 100) ’the average weight of the output of 7 feeds minus the average output of 9 feeds
