Open carding machine developed to solve several important issues (1) China has developed nearly 30 years of carding equipment history, long-term falters many reasons, in addition to the poor quality of the electrical control components, microelectronics with varying reasons, the most important thing is not the carding machine as a systems engineering task. Open carding machine is open section, carding section and section cleaning cotton dust composition, how to link up the various parts of organically must be holistic, including the arrangement of the process to select, dust configuration, equipment, piping 9 design, the suction set noil system, each suction point determined amount of wind pressure, carding electric centralized control cabinet design and so on, each part should organically supporting, as a system, into a single system. (2) On carding machine are required to use a reciprocating Reciprocating Bale Bale is open carding machine of the first process, intermittently falling bale thugs with turret reciprocated, as the order of the bale grab Take, was captured by the cotton beam output and the output of cotton cotton fan duct, through the front Condensate cotton or suction fan to the front of the machine of cotton inside. In the past, opening carding machine in the distribution of the vast majority of Bale Bale compared to disc, disc Bale reciprocating bale has two weaknesses, a limited number of packages piled up, can only put 20 multi-pack, the other is rotating crawl cotton beam during dispersion cotton beam size is large, grab a small beard inner and outer crawl cotton beam, with a mean weight of about crawling cotton beam 50mg ~ 80mg and cotton inside and outside walls block the plate with wire bundle rubbing phenomena arising in the crawl, affecting sliver quality. Using reciprocating bale plucker can overcome these shortcomings, stacking bales generally about 50 packages (one side), grab the beam evenly and fine cotton, cotton beam weighs 30mg (yield 500Kg / h). Since the disc and reciprocating bale plucker machine compared to no external wall panels, avoid rubbing the raw cotton between thugs and wall panels, reducing wire bundles and small miscellaneous generation, so that sliver knot mixed with a downward trend. Reciprocating Bale can use the outset beard catch small catch fine catch uniform mixture evenly, fiber is fully opening, back in favor of action to improve the impurity removal machine. Development FA006 reciprocating bale plucker satisfy the requirements of cotton spinning, cotton has been a user of all ages, the project 95 years as China Textile Machinery Industry Corporation and Technology Progress Award, China Textile Science and Technology Progress Award, National Science and Technology Progress Award. Bale now supply system has been improved in mechanical, electrical, higher degree of automation, performance is more stable and reliable. (3) On carding machine you must be configured serrated roller scutcher opening carding machine carding feed hopper feeding requirements of raw cotton to fully opening, showed a snow flake, and pre-sort, in order to reduce high yield carding carding burden, for in the process, the opening and cleaning units last one to be configured serrated roller picker with double dust knife and pre-carding plate structure. The advantage is high cleaning efficiency, the fiber has a pre-combing action, full opening of the cotton fibers are uniformly feed carding feed hopper to create the conditions. In order to shorten the process, Cheng Textile Machinery developed ZFA028 long positions blender and ZFA109 type three-roll scutcher arranged three roll clothing for core needle, coarse tooth and fine serrated, can effectively deal with the degree of opening Lower raw cotton. The machine features three clean cotton rolls have a continuous suction tube and the impurity wind hybrid adjustable amount of dust falling knife valves, high cleaning efficiency but little damage to the fiber. (4) Feeding system using a continuous cotton system is to ensure continuous feed hopper feed carding cotton tank for cotton stabilize an important part of the development of the original use of the pressure sensor is installed on the transmission pipeline cotton with analog PI regulator inverter-driven motor control to cotton, the result is the ability to adapt is not strong for cotton fluctuations, different card number Founding fluctuations caused by pressure pipe, adjust inconvenience. After much discussion and many times this test comparison, the final adoption of the new regulator, the use of two degrees of freedom PID plus analog control, the pipeline pressure was maintained at 80 + 5mm of water pressure on each cotton cotton box Box batt density, but with different numbers Founding carding, the cotton frequency inverter motor FA108E serrated roller picker can be stabilized soon, and with the card number is proportional to the Founding achieve precision continuous Feeding The purpose of ensuring the feed hopper carding cotton tank for cotton stable, uniform dry sliver played a guarantee. (5) The intermittent suction system ensures batch noil noil and dust suction system with high reliability and a sufficient amount of wind pressure is one of the key to a good start carding. According carding entire process air flow requirements, select the appropriate plate dust filter, fan, fiber splitter and pressing, etc., and choose good quality, reliable operation of the suction valve plate noil, specially designed electrical suction noil control system, made of imported components, PLC program control, to avoid falling within the sweeper stoppage of cotton produced in order to ensure continuous production carding of.
