The increase in card output directly means that more fibers need to be processed by the machine, if you want to get the same fiber release, then you have to increase the number of needles and teeth per unit time, there are three possible ways: (1) increase The number of teeth per unit area on the carding element; (2) increase the speed of the carding element; (3) increase the number of carding elements. 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. 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 first possibility is small, because rented fibers and high production require low-tooth needles, and fine fibers and low labor require high-tooth clothing. Second, a lot of work has been done on the speed of combing parts, further increases will be more difficult. For example, the output of the carding machine is increased from 25 kg/h to 60 kg/h, and the Syrah has to be increased to 750 r/min under the same fiber opening requirement.

300 electrons/min is technically difficult, it also causes more fiber damage. The third point is the number of daily rolls or adding pre-configured boards. Fasten rice bowls, etc. in the front and back.

Some manufacturers use workers or three spines arranged in parallel (there are also double spines down), the direction in which the teeth on the rollers line up with each other. The speed increases with the increase of cotton flow direction, such as 600, 1200, 1800c/min. The disadvantage of the licker-in is that the structure is complex and difficult to preserve.

Therefore, some spinning machines use pre-carding boards. The FA203 carding machine has two 70mm wide arc-shaped carding boards under the drum. As shown in Figure 2-15(a), it is composed of free board of comb board, dust removal knife, cotton board and bracket.

The arcade consists of a number of 0.8 mm thick teeth and 2.5 mm thick spaces, in order to distribute the serrations evenly across the width of the machine, and the teeth along with the spaces, as shown in Figure 2-15(b). 2.5mm, tooth depth A working angle 85°, 5mm. Street is 30°, 2 mm, the thickness of the cotton rod is fixed on the shell of the carding board with screws.

The distance between the feeding board and the first dust removal blade is called A; the distance between the tooth surface of the first carding plate and the tooth surface of the drum is 0.45-0.6 mm The distance of the area is called B; the distance of the second drop area is called the distance between the second cotton board and the arc connecting plate is called the third drop zone c. The distance of each interval is A: 43-48mm. 2B, 14-16mm, C: 6-8mm. One area removes large impurities, fine impurities and velvet in B area are excluded, and C area mainly excludes short lint.

The main requirement for spinning chemical fibers is to strengthen carding, A, so the three dumping areas B and C can be reduced, especially the three dumping areas B and C cannot have fibers falling off. The results show that the cutting street of the carding board has carded the cotton bundles and fibers on the surface of the drum (most of which are fibers on the tooth surface of the feeding layer, and the licker-in roller has not been effectively carded, so that the cotton entering the silk forest covered area is not carded effectively. The bundle is small and small, which reduces the load on Xinjinlong covering. It is beneficial to protect the Gemi card clothing, and give full play to the carding, impurity removal and uniform mixing between the Xilin flats.

It is also possible to avoid yarn defects with small leaks that are often clogged due to reticulation. The use of carding board is beneficial to reduce the cotton spinning time, but it does not improve the impurity removal efficiency, and has different effects on the impurity content of the cotton lap.
