Carding Machine Introduced By Textile Machinery

< p > > a href= "//www.sjfzxm.com/news/" > carding machine < /a > belongs to textile machinery. According to the spinning process, carding is an important process.

The preceding process of the carding machine is to open the cotton cleaning machine, and the latter is drawing frame (combing process) or winding machine (combing process).

Carding machine is used for processing cotton fiber and chemical fiber.

< p > working principle < /p >

< p > carding machine operates on the principle of loosening and separating the cotton (fiber) rolls from the previous process or the oil cotton (chemical fiber) layer supplied by the cotton box. It is all the cotton rings with curly speed become the basic single fiber like energy. In the process, the broken seeds, impurities and short fibers left by the flower cleaning process are removed, and then a certain specification of cotton sliver is stored and stored in the cotton tube for use in the drawing process.

< p > structural composition < /p >

< p > carding machine's structure is divided into three parts: (1) the pre combing part, including the thorn roller, the cotton roller, the feeding board, the dust removal knife and the small leakage bottom. Secondly, the main comb part includes Xilin, cover plate, doffer and big leakage bottom.

The surface of the cotton roller is provided with an axial straight groove, and the two ends are equipped with a pressurizing device.

The camber of the front end of the cotton plate is matched with the cotton roller to form a pressure opening to facilitate holding cotton.

The needle roller is the main component of the precarding part. It is a hollow roller, and the surface is embedded with saw teeth, and the speed is higher.

The dust removal knives below the puncture roller and the arc bottom with mesh or dust rods are used to hold the fibers and remove impurities and < a href= "//www.sjfzxm.com" > short velvet < /a >.

< p > Xilin and doffer are hollow rollers coated with card clothing.

Xilin has a large diameter, which is the main body of the whole machine.

The cover plate and cylinder are the main components of the main comb part. The total number of the root plates is 106~110, and the working cover is 41~43.

The shape of the cover is narrow and the section is T shaped.

The work of the cover plate is covered with a needle cloth, and the contact surfaces between the ends of the cover plate and the supporting rail are formed on the arc surface of the heel, and the height difference between the front and the rear of the arc surface is 0.5 to 0.9 millimeters.

The cover plate has a larger inlet gap and a smaller outlet gap, so that the carding effect is gradually enhanced.

All the cover plates are linked through the chain to drive slowly, and from the back to the front, they rotate and rotate.

Beyond the cover of the working area, the short, velvet, and some spinnable fibers caught on the needle surface of the work area are stripped off by the chopping knife and become a cover board.

After cleaning the cover plate returned to the working area, it is called the rotary cover plate carding machine.

The large leakage below the cylinder is composed of two triangular grids and arc light plates, which are used to hold the fibrous layer on the surface of the cylinder and to discharge part of the short pile.

The types of needle clothing or saw blades coated on the surface of cylinder, roller, cover, doffer and cotton stripper, the density and angle of the needle teeth, and the distance between the pins are determined according to the technological requirements.

Because the surface velocity of doffer is 1/15 ~ 1/30 of Xilin, some fibers on the surface of the cylinder are condensed on the surface of the doffer, and the fiber layer on the surface of the doffer is stripped by the stripped cotton roller.

The surface of the upper and lower rollers is smooth and hard, which has certain scavenging effect on the residual impurities in the web.

The loop bar is used to place the cotton sliver regularly in < a href= "//www.sjfzxm.com/news/index_c.asp > cotton sliver < /a > cylinder.
