General situation of development of multi-roll system of carding machine

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

In order to increase the output of the carding machine, the multi-licker-in system is being trial-produced on the high-yield carding machine at home and abroad. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. 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 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. Taking 1181e and a184 cards of Qingdao Textile Factory and Shanghai Textile Factory as examples, a systematic study on parallel double cards, large and small double cards, oblique row double cards and triple cards is carried out.

In the early 1960s, three-needle carding machines were also developed in the United States, and in the late 1960s, Pratt's 602 carding machine also adopted a double-needle carding system. In the 1970s, the French Sackham hp7 card used a double licker-in system, while the ku12 card of the former German ingolstadt company used a triple licker-in system. For various reasons, most of these multi-roll system cards have not achieved lasting commercial 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, mainly acts as a uniform opening, 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 the following basic characteristics: (1) The diameter of the licker-in (especially the diameter of the first part in China) is generally about 250 mm, such as the diameter of the KU12 three licker-in is 248 mm, and the diameter of the Plau601 double licker-in is 248 mm. It is 249 mm, and the diameter data of HP7, OK3, and A184 double licker-in are all 250 mm. (2) All card clothing companies are sawtooth. The change of sawtooth density is gradually increased by our development. The working angle can be gradually reduced in China. The inter-needle configuration companies generally use stripping configuration, but there are also carding configurations. Such as A184 carding machine. There are two kinds of speed, one is from small to large, for example, the speed of KU12 roller system is 920, 1350, 1800r/min; the speed of double-roller system is 750, 850riminG, and the other is from large to small, such as A184 , the speed of the first roll is 2300~2800r/min, and the speed of the second roll is about 1000r/min.

(4) Some manufacturers have also adopted the method of adding carding boards and dust removal knives to strengthen carding and impurity removal, such as the ok3 carding machine and three-needle roller carding machine produced by the German reutlingen company. On ITMA87, Hollingsworth's company exhibited the Trash MAC master, the first principle trash pickup licker-in, and the introduction of the first carding clothing and electrode technology selector. 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 in the tiA91, and Tianwang Taiwan launched the CM-efficiency and picking machine in the ITMA95.

Since the output and quality of carding can be improved, it is said that more than 5,000 units of this traditional machine learning have been sold. At ITMA99, Truetzschler introduced the DK903 high-yield carding machine, and DK903 continued to use the three-bite-in system (while some other famous international textile machinery companies in China developed the single-bite-in roll system in the same period).
