Defects of Card Clothing for Carding Machines

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

Carding, cleaning, and mixing, the role of fibers closely related to clothing, has proved that the performance of card clothing plays a key role. 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. 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. Flexible wire applications have been on the cards, and the development of wire over the past two decades is a very fast, universally applicable carding machine. In particular, more than 5 sets of metal card clothing meet the requirements of processing various chemical fibers and high production, so that further I lap the ratio of high speed, high output, MCC application development and chemical fiber carding industry will grow rapidly.

Compared with the elastic card clothing company, the main metal card clothing of the carding machine has disadvantages (1) In the production of pin gears, it is easy to roll hard fragments or the cotton ball is damaged, and the bad ones are not easy to repair after rolling, so that the bad parts must be removed in a large area and the rolling is heavy bag. (2) The metal card clothing of the existing technical specifications has poor adaptability to spinning slender structural fibers and extra-fine yarns. (3) Due to the short tooth shape, the needle surface cannot store fibers, so there is a lot of flying dust.

These shortcomings can be corrected by taking appropriate measures and designing new tooth profile specifications. 3. The garment should be combed for the following effects: (1) Good ability to puncture and hold part of the fiber, so that the fiber can often be combed at the tip of the needle and the other needle surface. (2) The fibers tend to move toward the other surface of the needle from a needle, passing between the fibers in the cylinder head, in the carding cylinder with fibers passing to the doffer.

(3) Appropriate needle gap capacity and good suction and release capacity to improve the uniform material mixing and other functions of the carding machine. (4) The needle teeth should be sharp, smooth, wear-resistant and smooth. Sharp needle teeth, strong ability to wear and grab fibers, good carding effect.

Acupuncture and teeth are sold lightly, it is not easy to pull out flowers, and there are few fibers plugged into the acupuncture teeth. The needle teeth are wear-resistant, and the needle teeth are sharp and the skin lasts for a long time. The needle surface is flat, so that the distance between the parts can be accurate and close, and it is suitable for proper carding and transmission of fibers, so that the fibers cannot form neps on the needle surface.
