Qing Tonglian's requirements for process equipment

The requirements of the cleaning and carding unit for the process equipment The requirements of the blowing and carding unit for the opening and cleaning equipment are that the opening and consumption unit can efficiently open, remove impurities, mix materials uniformly, and have better reliability and stability. 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 output cotton flow is uniform, the knots are less and less, and the fiber cell damage and short staple are less.

The requirements for the opening and cleaning process are to carry out fine cotton picking, multiple bales to take, multi-silo cotton blending or other favorable policies and measures of enterprises, so that the fibers can be fully mixed by students and young children. The opening of the fiber should be more loose and less hitting. From extreme to thin, the fibrous tissue of rabbits is severely damaged without too much damage.

A high-efficiency dust collector is used to remove fine dust and fine product impurities from the raw cotton. Carding is an extremely important process in cotton spinning engineering. The carding machine should expand the carding, improve the carding ability and carding effect.

Reduce the impurities in cotton spinning and improve the clarity of the cotton web. The self-leveling of the carding machine is an important measure to solve the special deviation and weight unevenness of the yarn. The carding machine controls the weight drift of the sliver, reduces the non-uniformity of the sliver weight, ensures that the sliver quantity of a single machine meets the requirements, and can reduce the difference between machines.

The capacity of the self-levelling machine is limited to a certain extent. To improve the uneven weight of the original sliver, a uniform sliver can be obtained under the combined action of the carding and the self-levelling machine. The process flow of the blowing and carding unit The blowing and carding unit has two processes, one is the concave cotton process, and the other is the non-return cotton process. In the process of unwinding, in order to obtain the same amount of raw materials for each carding feeding box, the spare raw materials are gradually fed from the first raw material in the cotton distribution pipeline, and finally returned to the feeding cloth.

The cotton recycling process is better than the cotton recycling process. Can adapt to the change and increase or decrease of the carding machine. The single-pass cotton process flow of emotional carding is shown in Figure 3-26.

The no-return process uses the exhaust volume of the cotton box and the pressure change of the pipeline to control the input of the feeding box. Under normal conditions, the line pressure is proportional to the fiber stock in the feed tank. The more fiber content in the feeding box, the larger the air outlet cover, the greater the pressure in the box, and the slower the material transfer speed, and vice versa.

By adopting the method of pressure balance, the quantity and density of materials stored in each feeding box can be uniform.
