Article and the rubber roller beating, swimming and so on question reason analysis and its matching management

And a rubber roller beating swimming, the analysis of the causes of the problems such as 2020 - and its matching management 06 - Drafting of 20 Homer rubber roller is the important equipment, which the article and the rubber roller and roller nip control function of the fiber layer is much larger than roving, spinning process, or rubber roller and rubber roller problems bearing with bad, will lead to improper roller and rubber roller configuration, that cause the change of the yarn evenness and weight, the last working procedure to improve; Although in winding process can be set parameters to adjust, but the production efficiency and yield in winding process. Therefore, to strengthen the management of the article and the rubber roller, correct use, maintenance, rubber roller, to improve the yarn quality is of great importance. Problems arising from the rubber roller used in the daily check for the article and the draft channel, often find glue roller beating head is bigger, a lot of rubber roller and axial winding problem, maximum swimming to about 4 mm; Swimming will beat serious and large amount of rubber roller replacement to the former experiments, have created serious mechanical wave. Rubber roller to beat to beat serious rubber roller, shaft core bending more, mainly because of lack of oil or improper pressure. And a rubber roller maintenance cycle is 15 d, to the maintenance cycle gas discovered oil shortage problem is more common. Analysis on reasons: first, due to the rubber roller high-speed operation, easily after lubricating oil is heated issue from the bearing; Secondly, in the process, and a rubber roller around flowers, the lubrication grease with bound processing erase; Again, or replace the bad roller bearing production, the quality management consciousness is not strong, not add lubricating oil, oil shortage caused by roller. Rubber roller winding will swim for roller bearing, some rubber roller winding problem largely disappeared, some problems still exist. We open winding roller bearing, and check the internal found when swimming glue roller head center hole all have varying degrees of wear, some internal ball bearing also have wear, or even fall off. Article and the rubber roller in the operation, its axial is on ball and the matching of the center hole to fixed, when the ball or central hole after wear and tear, vibration in operation at the same time, both will give rubber roller to generate a certain amount of thrust, appeared in the process of rubber roller in the operation of swimming around. Drawing frame causes of 12 cm mechanical wave often found in routine tests in there was a mechanical wave crest is 12 cm, through to the front roller, transmission gear has not been over checking also found the problem, after replace the former plastic roller mechanical wave elimination. Before the draft, which is in 12 cm mechanical wave dynamic inspection of rubber roller, found three problems: one is the rubber roller basic normal appearance, before the one replacement rubber roller testing for many times, a few new rubber roller bending problem; The second is rubber roller before beating obviously; Three is evidently rubber roller before swimming. Has different degree of mechanical wave sliver from roving and spun yarn until the cloth quality test, found that slight sliver of mechanical wave after roving frame and spinning frame of draft, reflect the effect on spinning spectrogram, serious will directly affect the yarn evenness CV value, cloth fine, coarse weft weft and the defects of cloth, so the bad condition of rubber roller can not be ignored. Articles and cots selection and drafting rollers linear velocity, high calorific value is big, easy to wear and winding. Rubber roller the selection and use of improper, will seriously affect the yarn quality and production efficiency. Article and the selection of the rubber roller is based on the premise that don't appear mechanical wave, to ensure the normal operation of the machine to the greatest extent, reduce the cotton stick around. Rubber roller and the second leg before the rubber roller is particularly important, its hardness selection should be based on factors such as the yarn quality comprehensive decision; On the premise of meet the quality requirements, with slightly Gao Weiyi hardness, low hardness, higher requirements to the environment temperature and humidity. Therefore, should be used in production of high hardness rubber roller. Rubber roller management between rubber roller 1) Between the rubber roller must pay attention to the management of rubber roller, bearing, and a rubber roller before the computer to check, once found that there was no question of coaxial, all cannot use; Keep alignment of new rubber roller to spot check, so as not to cause harm to the yarn quality. 2) Article rubber roller between staff to cooperate and wipe, flat car in a timely manner to add lubricant, replace the bad rubber roller and bearing, not regular computer inspection problems of rubber roller and bearing, supervise shift used correctly. 3) Temporarily without rubber roller, pay attention to the bearing anti-rust, lest cause rubber roller turn bad, make the yarn produces do not divide evenly. 4) Do the cycle management of rubber roller, if the cycle with rubber roller surface coatings appear wear away, then need to surface treatment, to stabilize the production. High temperature season for individual yarn varieties of rubber roller random spot check on status, guarantee the stability of the quality of yarn. 5) Quality inspection, strict enforcement of rubber roller get on the bus for replacement when the rubber roller must add lubricating oil, so as not to cause the lack of will in turn cause a dry anomalies. 1) operation management Strengthen worker protection consciousness of rubber roller, understanding the causes of bad rubber roller as well as to the quality of spinning; Especially on the rubber roller wrapped flower cannot be removed with a knife, to prevent scratch rubber roller, and even lead to rubber roller scrap. 2) Counterpart to do a good job in succession, the successor to do a good job of acceptance: touch first rubber roller drive, ensure the normal working of rubber roller; On a parking or boot stage to do a good job of unloading. 3) Workshop should spare rubber roller and bearing for roller in night shift, to change the problems of bearing; Should add lubricating oil when replacement, to ensure the normal working of rubber roller. In a word, drafting of spinning roller is the important equipment, plays a key role in the quality of semi-finished products and finished products. Textile mills should do a good job in comprehensive detection, control and management to quality control, put an end to quality fluctuation. （ Source: the textile equipment online)
