The carding machine is an important part of the front spinning equipment, which has a great impact on the production and quality management of the sliver. At present, the performance and structure of the carding machine can be researched, improved and developed by technical enterprises in the textile industry all over the world. . Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.
The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Grinder A spinning machine that turns fiber strands into rovings.
The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. The following 12 aspects are the main working direction of the current carding machine development. 1. Output At present, the main output levels of domestic and foreign cards are mostly around 100 kg/h, such as DK 903 is 120 kg/h, C 51 is 120 kg/h, C 501 is 120 kg/h, CMH and MK 5D are 100 kg/h kg/h, Indian LC 300A is 80 kg/h, domestic FA 221B is 85 kg/h, FA 225, FA 232 is 100 kg/h, FA 203 is 80 kg/h.
2. Speed Due to the high ratio of industrial output, the speed of Xinjinlong is also relatively high, such as DK 903 is 400 ~ 550 r/min. C 51 is 300～600 r/min, C 501 is 500～600 r/min, LC 300A is 350—550 r/mino CMH is 500 r/min, MK SD is 425～770 r/min, FA 225 Xinjinlong has a maximum development speed of 549.8 r/min, and FA 232 Xinjinlong has a speed of 400～600 r/min. The licker-in speed and the sliver speed have their own corresponding cost increases. For example, the maximum working speed of the MK 5D licker-in is 1 500 r/min, and the sliver speed is 350 m/min, while the maximum operating speed of the MK 5 is only 250 m. /min, Marzoli CX 300 has a speed of 300 m/min, Marzoli C 501 is 350 (maximum) m/min, and DK 903 has a maximum speed of 400 m/min. 3. Direct cotton feeding was used by ITMA Company in Milan, Italy. In 1983, Swiss Rietc (Lida) Company first used direct cotton feeding. In 1995, ITMA Company in Paris, France, and German company Trutzschler (Tuluzler) also used a kind of direct cotton feeding. Forward feed L, its DK803 card.
In CITME2(X)O, domestic FA232 and FA225 are also used in the cotton feeding direction, and t is used to feed cotton: in the direct direction, it can reduce fiber damage and facilitate fiber transfer. Therefore, it can be predicted that forward cotton will be used for combing in the future. feed. 4. Double licker-in and triple licker-in systems have been tried many times in China in recent decades, but due to the limited level of information technology and economic conditions in my country at that time, they could not fail to achieve long-lasting commercial enterprise success. TruU.schler exhibited at TTMA 95. The DK 803 card adopts the triple licker-in system. At CITME 2000, the DK 903 card continues to use the triple licker-in system, and the domestic FA 225 also adopts the triple licker-in system. , The main reason why we can succeed in the design of the new three-licker-in system is that the development ability of contemporary students' carding analysis technology and the social people's mastery of carding related technologies are more profound. Using carding technology, how to further improve the prelicker? The development of the capacity of the body part, a cover to reduce the work done in the cylinder pressure, and fibrillation can be a single future study.
5. Generally, Mazo? 501 card, 350 mm, whose licker-in diameter (which itself is conducive to the arrangement of the dissolution zone) can be used to strengthen the opening and cleaning of Chinese fibers can be used. The licker-in rollers are mounted on three carding boards with 3 suction blades and two deflections (the amount of deflection of the blades can be adjusted in two miscellaneous areas of noil). It is said that the cabinet setting, completes 90% of the work of impurities, but also can reduce the wear and tear of clothing, improve the quality of combing. Other cards are also mounted on the licker-in opening plate with the dusting knife.
