There are many varieties of spinning machinery, machine structure, use and performance Each one is different. According to their order in the process flow, they are divided into:
(1) Automatic cotton picking machine: used to grab small pieces of cotton layer by layer from the proportioned cotton bales, suck them through the cotton condenser, and send them to the subsequent machine through pipelines for use. There are two types: rotary type and reciprocating type.
(2) Cotton blending machine: It is used to fully mix, shred, loosen and remove the small cotton pieces sent from the cotton picking machine, and then send them to the subsequent machine through pipelines for use. The varieties include automatic cotton blending machines, multi-bin cotton blending machines, mixed cotton opening machines, and double-box cotton feeding machines.
(3) Cotton opener: used to fully hit, tear, open and impact the small cotton pieces sent from the cotton mixing machine through the dust grid to remove impurities such as cotton seeds, leaf scraps, cotton stalks, dust, sand and gravel. The cotton pieces are separated and dropped into the dust chamber, and then the small pieces of cotton are sent to the subsequent machine for use through pipelines. Varieties include: brad-type cotton opener, porcupine-type cotton opener, comb-type cotton opener, saw blade type (saw-tooth type) cotton opener.
(4) Cotton cleaning machine: used to further loosen and remove impurities from the fed raw materials, condense them into a longitudinally and transversely uniform cotton layer through the dust cage, and make cotton rolls (or cotton rolls) through the rolling mechanism. type chemical fiber roll) for use in subsequent machines, including double dust cage cleaning machines and single dust cage cleaning machines.
(5) Rolling machine: further process the fed cotton to make cotton rolls of different counts and play a certain role in opening and removing impurities.
(6) Carding machine: used to open, remove impurities, comb and mix the cotton rolls made by the blowroom cotton machine to further remove impurities and short lint, and turn the small curled cotton balls into into parallel single fibers and made into slivers for use in subsequent machines.
(7) Draw frame: merge several slivers , apply drafting to make a single sliver to improve the uniformity of the long sliver segments and the straightness and separation of the fibers in the sliver.
(8) Roving frame: through drafting, twisting, Winding processes the drawn strips into roving packages for use in the next process. There are two types of roving frames: supporting spindle type and hanging spindle type.
(9) Spinning frame: The fed roving strip-type cooked sliver is drafted into thin strips, which are drawn and twisted into spun yarn and wound on the spun yarn tube.
(10) Winding machine: extract the spun yarn from the bobbin , give a certain tension to remove neps and impurities, and wind it into a cheese yarn with large capacity, good shape, and meeting the winding requirements of subsequent processes.
(22) Doubling machine: slave tubeThe single yarn is extracted from the yarn or bobbin, and then two or more single yarns are combined, given a certain tension, and wound into a combined yarn bobbin. There are two types of doubling machines: groove doubling and yarn guide doubling.
(12) Twisting machine: pulled out from the doubling yarn bobbin The yarn is twisted and wound on the bobbin. There are three types of twisting machines: single-twist twisting machine, double-twist twisting machine, and triple-twist twisting machine.
(13) Yarn shaker: extract single yarn from the package yarn Plied yarn is wound into skeins of a certain length for transportation in packages or for bleaching and dyeing.
(14) Sliver rolling machine: It is the previous process of the combing machine. It drafts several cotton slivers into small rolls for use by the combing machine.
(15) Combing machine: combing the fibers, significantly Improve fiber straightness and parallelism. At the same time, short fibers, neps, and impurities in the fiber clusters are removed. This machine is used for spinning high count yarn. Among the complete sets of spinning machinery, there are also auxiliary machinery and equipment, inspection instruments and equipment, textile machine parts and textile equipment, etc.
