In carding projects, the role of the licker-in saw blade is very important. 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). 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.
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 cylinder and the licker-in blade will cover the card clothing, just like the relationship between a person's teeth and the stomach, if a person does not have good teeth, it will not be chewed and swallowed, and it will not be delivered to Digestive Spring.
Similarly, the cylinder and the flat garment are difficult to card high-quality wool if the rod blades are used to promote fiber opening and removal of unwanted impurities. The action of the blade licker-in is particularly important to obtain the comb shape on the machine. The characteristics of foreign licker-in saw blades are that the cotton type has a small angle and a large number of teeth per inch, and the chemical fiber type has thin teeth and a large angle.
(1) Jinjing licker-in saw blades Japanese company Jinjing Industry produces licker-in saw blades, mainly TC45H, TC50H, TM45 and TU45H. Figure 1-21 is the toothed blade licker-in Jinjing, and Table 1-13 is the main specifications and blade thorns of gold. (2) Graff thorn-level saw blades The licker-in saw blades produced by the Swiss Graf company are shown in Table 1-14.
(3) The farrar blade tooth shape and specifications are shown in Table 1-15. (iv) The friction coefficient of chemical synthetic fibers in the rolling saw blade test conducted in the Soviet Union can easily lead to a kind of static electricity, so it is economical to transfer the ability to Xinjinlong. In order to solve our social problems by ourselves, thin barrels and large-angle licker-in saw blades can generally be used.
But what is the appropriate tooth distance and working angle? In response to China's environmental problem, the Soviet Union, as the central state machinery and equipment parts design and manufacturing technology and scientific development research institute and the Ivanovsky Comprehensive Pharmaceutical Factory, have researched and made several new saw blades. , and carry out the enterprise test with the original saw blade. The analysis of the results shows that: when processing viscose and polyester fibers, the working angle should be refined to 105°, the tooth pitch is increased to 8 mm (knife-47 type), the quality of cotton net and sliver has been improved, the fiber bundle is decomposed well, and the knot is less, which is conducive to promoting the transfer of fibers to Xinjinlong. If the teacher increases these working angles to 120°(Knife-48 type), the knots are increased differently, and the quality management of cotton webs has decreased significantly.
Moreover, due to the self-thinning of the Ting-47 type, the number of teeth acting on one centimeter of whiskers per second is reduced from 4380 to J3360, so they can effectively reduce fiber damage. Combing the needle teeth for thinning tests, with large angle blades, is ineffective. In particular, the processing of impurity-containing cotton fibers can cause wool, sliver waste rate, and fine fibers can be spun.
Soviet carding type multi-O-2 to licker-in blades (working angle 75°, 6.5 mm from the street). Branched derivative yarn instead utilizes the 85 blade angle treatment°When working properly, the fibers do not sink deep, and the longer fibers can be grasped along the Kawasaki through centrifugal force to protrude the Xinjinlong card clothing and the residues of the fiber neps below Xiao. 75, respectively, the role of this collaboration and blade, and the role of Xinjinlong card clothing Ying Zhanfu°, 60 when dealing with short fiber rods°, the blade working angle is also larger than the wall.
