In order to increase the output of the carding machine, domestic and foreign enterprises are developing the high-yield carding machine to trial-produce the excessive licker-in system. 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.
Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. 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.
For example, my country has done a system of parallel double licker-in, large and small double licker-in, oblique double licker-in and triple licker-in on 1181E and A184 carding machines in Qingdao (Textile Machinery Factory) and Shanghai. In the early 1960s, the United States also tried a three-licker-in card; in the late 1960s, Platt's 602 card also adopted a double-licker-in system. In the 1970s, the SACM HP7 card in France mainly used a double licker-in system; while the (former) KU12 card of the German lngolstadt company adopted a triple licker-in system.
Due to various social problems, most of the above-mentioned cards with multiple licker-in systems have not been able to achieve more lasting commercial bank success. During the 13 years from ITMA83 to ITMA95, the world's leading graphics card manufacturers have not used too many licker-in systems on their carding machines. The company used the only Italian Mazuo Li who had double licker-in in the C300, CX300 carding machine system, but due to its low speed, the first The speed of the second licker-in (14.5 ~ 29.0 rpm) is mainly used as a uniform opening action, so it cannot be compared with the traditional double-system licker-in. Mazzoli also eliminated the double-card system licker-in in its follow-up production of the CX400.
For the convenience of discussion, the licker-in system before ITMA83 can be referred to as“Traditional licker-in system”The traditional licker-in system has some basic characteristics: (1) The diameter of the drum (especially the first diameter) is generally about 250mm, such as KU12 mm in diameter, 248Platt601 double thorn is 249mm, diameter HP7, DK3, A184 double thorn drum diameter is 250mm. (2) All card clothings are serrated, the sawtooth density gradually increases, and the working angle gradually decreases. The configuration between the needles is generally a stripping needle configuration, but there are also carding configurations, such as a184 carding machine. (3) The speed of the licker-in is divided into two forms, one is from small to large, with the speed of the licker-in KU12 3 licker-in systems are 920, 1350, 1800 r/min; 2 licker-in double 750,850 r/min Sub-AP-2081 system licker-in speed.
The other is from large to small, such as A184, which is the first speed licker-in 2300 to 2800 rpm, and the second licker-in speed is about 1000 rpm. (4) Some manufacturers also use additional carding plates and dust removal knives to strengthen carding and impurity removal, such as DK3 carding machine and German Discovery Reutlingen Textile Enterprise Technology Development Institute designed and trial-produced Three licker-in carding machines, etc. On ITMA87, Hollingsworth's company exhibited the trash MAC master device, the first-in-principle trash pickup licker-in, and the introduction of the first card clothing and cleaning technology rice identification machine.
After this, the world's textile machinery companies used similar technology for the rest of the picking device, such as Trützschler launched the CVf3 type at ITMA91, and Tianwang Taiwan launched the CM-efficiency and picking machine at ITMA95. After careful analysis and study of the development of the multi-drop cylinder opening and depleting cotton technology, Truetzschler will transfer this information technology to the carding machine. In 1995, on ITMA95, he successfully launched a DK803 high-yield carding with three licker-in system. machine.
