Carding function of carding machine

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

For the purpose of the experiment of claim 1, the task of understanding and processing the flat card. 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. 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). 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.

2. Understand the main economic structure and main influence of a flat carding machine. 2. Basic theoretical knowledge In the cotton lap or cotton layer made of raw cotton or cotton-type chemical fiber after the process of opening and cleaning, the fibers are mostly bundles and blocks, and there are many impurities, and students need to conduct in-depth and meticulous carding. Processing in my country . The function of the carding machine is to further improve the decomposition of bundles and block fibers into single fibers through more detailed carding, remove impurities and defects, and make packages with certain technical specifications.

Therefore, the tasks of the flat carding machine are: 1. Carding. Bundles and lump fibers are carefully combed, separated into single fibers, and the fibers are as straight and parallel as possible; 2. Clean up. Further remove impurities, defects and some short fibers in the semi-finished feed; 3. Mixing.

Under the premise of dissociating into single fibers, different characters and proportions of fibers and fully mixing to form uniform carding strips; 4. into strips. In order to facilitate the processing, storage and transportation of the next process, the fiber material is made into a sliver (commonly known as raw sliver) that meets certain specifications and quality management requirements of the enterprise, and the circle with the development law is placed in the can. Carding machine plays an important role in the spinning process, the fiber bundle block carding machine is separated into single fibers and fibers straight, and parallel to the drafting process under the degree of yarn tenacity, the degree of yarn breakage, etc. Dryness is closely related; the quality and uniformity of the tying yarn are determined to a large extent by the quality of the carding machine to remove impurities.

The important role of carding is achieved mainly by relying on the action of the needles on the fibers. Two needle tooth surfaces with a certain grip on the fiber and with a smaller gauge move relativistically, and the fibers are affected in one of them. Due to the relative research direction, tilted policy angle, speed and direction of relatively independent movement of the needles on our two needles, the main nature of the interaction between the two mutual supervision effect The general methods of enterprises can be divided into the following three types : To sort out the related effects——There is a problem between the two mutually assisting needle faces. Relatively increasing speed, the result of relative increasing motion is tip-to-tip; stripping action——There is some relative Chinese speed between the two needle faces, and the result of other movements is that the needle tip is opposite to the needle back; improve the management effect——There is a relatively high velocity between the two mutual learning needle faces, and the result of the relative lack of movement is needle back to needle back.

3. Experimental teaching content 1. Schematic diagram of FA201 type carding machine 2. Understand the organization of the carding machine, which can be composed of a flat plate, which needs to be carded. The main control of the computer is to feed the data to the student part, the pre-carding part, the main carding part and the system output design part personnel composition. (1) Feeding them part: It is mainly composed of cotton roll rack 1, unwinding roller 4, cotton feeding plate 5, and cotton feeding roller 6. The function is to ensure the quantitative feeding of raw materials. (2) Pre-carding part: It is mainly composed of licker-in 7, dust removal knife 8, licker-in carding plate 9, triangular drain bottom 10, etc. Its function is to analyze the raw material information for preliminary carding and impurity removal.

(3) Main comb part: It is mainly composed of Xinjinlong 11, cover plate 13, upper cutter 14, rear cover plate 12, front upper cover plate 15, needle copy door 16, front lower cover plate 17, large leak bottom 19, etc. , the function is to carry out in-depth and meticulous carding, impurity removal and mixing of raw materials.
