Description

A micro-strip breaking process

technical field

The invention relates to the technical field of textiles, in particular to a micro-strip breaking process flow.

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, from a technical point of view: there are many ways, among which the cotton matching solution is the best solution. Effectively, it is an extremely important technical measure to select and match individual colored cottons that have been pre-combed in advance, but to obtain pre-carded colored cottons, it is necessary to go through the pre-production process of tearing and packaging the carded colored strips or combed strips process.

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 problems, the present invention provides a micro-sliver breaking process, which includes spinning colored cotton fibers through cleaning, carding, or combing and pre-combing colored cotton slivers, or colored cotton combed slivers It is manually transported to the preparation workshop before the cleaning process to tear the sliver and pack the process. It is characterized in that: the micro-sliver breaking device is matched and installed on the carding machine or combing machine to run synchronously, and is combined into a combined sliver loosening machine. The fiber production machine produces and outputs loose sliver fibers, which are transported through pneumatic pipelines and collected in the automatic collecting and feeding machine for grasping and feeding. It becomes a loose fiber cotton bale under the action of bales.

The micro-strip breaking process is characterized in that: the micro-strip breaking device 18 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 pressure shaker Frame device 6, drafting roller 7, drafting top roller 8, output cotton guiding plate 9, collecting and collecting cotton hopper 10, cotton transporting pipe 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 Equipment such as receiving and feeding equipment 12, fan cotton flow conveying device 13, and double box baler 14 are packed, so that colored cotton loose fibers are collected and packed into colored fiber bags, which are used for formal colored cotton spinning production.

The micro-sliver breaking process flow, the production of the pre-carded sliver of the colored cotton spinning is processed and produced by a micro-sliver breaking device, and it is characterized in that: the packaging process flow of the pre-carded sliver of the colored cotton spinning is controlled by a cleaning machine (15), carding machine (16), combing machine (17), miniature sliver breaking device (18) and fan cotton flow conveying device (13) form assembly line production, and the dispersive cotton fiber of backward process output, through ring After the cotton warehouse feeder (12) completes the collection task, it automatically grabs and feeds, and is transported by the fan cotton flow conveying device (13), and is packed by a double-box baler (14), forming a fully mechanized The pre-carding process of the colored cotton spinning fiber produced.
