Micro-strip breaking device and process method

technical field

The invention relates to a micro-strip cutting device and a process method, belonging to the technical field of textiles.

technical background

China is a powerful country in textile technology in the world. In recent years, a large number of new colored cotton spinning mills have emerged in the economically developed areas of the southeast coast. It is another branch of high-tech industry that combines traditional cotton spinning theory with color technology. Colored cotton Spinning production is difficult and the process is complicated, and there is a lot of room for improvement in equipment technology.

"Color knot" is an important quality term in the process of yarn quality control in colored cotton spinning mills. If the quality problem of "color knot" is not well controlled, a large number of cloth surface quality repairs will occur, which will greatly increase the quality cost. In severe cases, it will cause the finished product to become a full amount of waste, return the claim, affect the delivery, and other large economic and corporate reputation losses. To solve the problem of color knot quality, there are many technical methods, among which the cotton blending solution is the most effective. It is an extremely important technical measure to select individual colored cotton that has been pre-carded in advance, but to obtain pre-carded colored cotton, it must go through the pre-production process of tearing and packaging carded colored strips or combed strips.

At present, the production process of pre-combed fiber processing in colored cotton spinning mills is: colored cotton - cleaning - carding - combing - manual transport of carding sliver or combed sliver to the tear strip - manual tearing Feeding and feeding of the sliver machine—feeding the shredded cotton sliver to the baler for baling production, the labor intensity is very high, the production efficiency is low, and the cost is high.

Contents of the invention

In order to solve the above-mentioned problems, the present invention provides a kind of miniature sliver breaking device and production process flow device, tearing sliver includes the centralized transportation of cotton sliver from cleaning to carding or combing workshop for pre-combing of colored cotton spinning fibers, The cotton sliver is fed to the sliver tearing machine continuously manually, and the sliver is broken by the sliver breaking machine, and then piled up manually, fed to the baler, and packed into pre-carded bales. The device is matched and installed on the carding machine or combing machine to run synchronously, and is combined into a combined sliver loose fiber production machine, which produces and outputs sliver loose fiber, and the output sliver loose fiber is transported through a pneumatic pipeline and collected in the In the automatic collection and feeding machine, the cotton is picked and fed, and it becomes a loose fiber cotton bale under the action of pneumatic pipeline transportation and cotton bales;

The miniature sliver breaking device 18 is characterized in that: it includes a micro-power cotton-feeding centrifugal fan 1, a roller seat frame 2, a roller seat block 3, a feeding roller 4, a feeding top roller 5, a spring-loaded cradle device 6, a pulling Stretching roller 7, drafting top roller 8, output cotton guide plate 9, collecting cotton hopper 10, cotton transporting tube 11;

The working process of the miniature sliver breaking device 18 includes feeding the single carding sliver output by the carding machine or the combed sliver output by the combing machine to the low-speed control roller nip composed of the feed roller 4 and the upper top roller 5 by the leading sliver. Feeding at the drafting roller 7 curved surface arc control area, gripping the jaws of the drafting roller 7 and the drafting top roller 8 and pulling at a high speed, so that the uniform sliver fed originally can be stretched in the drafting grip Intermittent "structural thinning and destruction" of the sliver occurs in the middle of the holding distance, and then the sliver output by the nip of the drafting roller 7 and the drafting roller 8 becomes a wavy, chain-like dispersion of one thickness and one thinness. The fragments of cotton bundles are scattered in the collecting and guiding hopper 10 through the output cotton guide plate 9; then through the cotton conveying pipe 11, the wind force, due to the influence of the weight of the cotton block itself and the difference in volume, makes the different layers and sections in the air duct The wind speed continuously changes in size and size, which in turn accelerates the "cracking along the way" of the small cotton pieces, and then the blades of the cotton-transporting centrifugal fan 1 are flexed and hit at high speed, so that the air fiber flow after the outlet of the cotton-transporting centrifugal fan 1 Become a pure loose fiber air fiber flow;

The micro-sliver breaking device 18 is installed at the tail of the carding machine 16 or the combing machine 17, which can be combined into a combined machine for the production of new raw sliver or fine sliver, so that the traditionally used carding machine 16 or combing machine 17 Add another production function of cotton sliver or loose fiber-shaped small cotton block. This dual-function production equipment is very important in colored cotton spinning mills. It is very suitable for the production characteristics of colored cotton spinning mills. Under normal circumstances, the carding machine 16. The combing machine 17 produces sliver. When it is necessary to produce pre-combed colored cotton, the carding machine 16, the combing machine 17 and the miniature sliver breaking device 18 can be combined to work, and the carding machine 16 and the combing machine 17 can be combined to work together. The output cotton slivers are connected to the miniature sliver breaking device 18, so that the carding machine 16 and the combing machine 17 continuously output the pre-combed colored cotton loose fibers, and then with the help of the subsequent total cotton conveying air duct 11 and the cotton collection warehouse Collection and feeding equipment 12, fan cotton flow conveying device 13, double-box baler 14 packaging and other equipment, so that the colored cotton loose fiber is collected and packed into colored fiber bags, ready for formal colored cotton spinning production;

The production process includes continuous production of cotton slivers from cleaning 15 to carding 16 or combing 17, and then manually transported to the tearing room, and manually feeding the sliver to the sliver tearing machine without interruption. The cotton sliver is torn off by the sliver breaking machine, and then the shredded cotton sliver is manually fed into the baler to be made into a pre-carded cotton bale. The sliver device 18 outputs the loose fiber of the sliver to the outside, and then the annular cotton bin feeder 12, the fan cotton flow conveying device 13, and the double box baler 14 carry out the whole process of mechanized production, and complete the production and packing task of the pre-combed loose fiber. A new fully mechanized production process has been formed: dyed cotton - cleaning 15 - carding 16 + micro sliver breaking device 18 - combing + micro sliver breaking device 18 - annular cotton bin feeder 12, Fan cotton flow conveying device 13, double box baler 14;
