Product description

The carding machine consists of a hopper, an upward release roller, a downward pre carding ring, a tekine and a flat plate machine. The cylinder and power plant are composed of seven parts. The specific mechanical structure of the carding machine is a woolen bucket and an upward opening roller. Two groups of connected downward pre carding cylinders form a downward pre carding ring. Two Tekes, two cover machines and finishing cylinder are used. The transfer between tecin and cover plate machine and finishing cylinder is completed by suction machine.

Product function

In terms of equipment composition, it fully adopts the advantages of existing carding machines, discards their shortcomings, appropriately simplifies the equipment composition of pre carding part to give full play to its efficiency, greatly strengthens the equipment composition of carding part, significantly reduces the damage rate of coarse and miscellaneous cashmere fiber, improves the quality and grade of cashmere without wool, simplifies the production process and reduces the equipment cost.

The carding machine is scientific in principle, reasonable in structure, compact in structure, energy-saving, and reduces the equipment cost; it improves the function of the carding machine, significantly reduces the coarse and impurity content of the finished cashmere, greatly reduces the damage rate of the cashmere, and improves the quality and grade of the non Plush.

The carding machine is composed of a carding hopper, an upward release roller, a downward pre carding ring, a tekine, a cover plate machine, a finishing cylinder and a power unit. The main features of the carding machine are that the downward pre carding cylinder, the tekine and the cover plate machine are equally divided into two sets, and the transfer between the tecyn, the flat plate machine and the finishing cylinder adopts the suction machine; the carding machine saves electricity, reduces the equipment cost and improves the productivity, It can significantly reduce the coarse and impurity content of finished cashmere, and greatly reduce the damage of cashmere.

A spinning machine in which the primary processing raw materials are separated and combed into single fiber state to form a network fiber thin layer and then assembled into synthetic fiber strips. Due to the different fiber types and process requirements, carding machines also have different structures, such as carding machine, carding machine and hemp carding machine.

After carding, many impurities and defects have been eliminated. The fibers with different qualities and colors are fully mixed, and the fibers are initially straightened and directional. These are important conditions for producing high quality yarn. However, most of the fibers still have hooks, which need to be straightened in subsequent processes.

Carding is a key process in the web forming production of dry needled nonwovens. The main function of carding machine is to further disperse and mix the loosened fiber clusters By using the mutual movement between the card clothing on the surface of the pair of rollers, the single fibers are interlaced with each other, and a uniform fiber net is formed by the curling and friction of itself, and then the netting blanket is laid and overlapped to form a net blanket for consolidation by the needle punching machine. Before the cotton layer enters the carding machine, the feeding roller should be used to hold the cotton layer effectively, so that the cotton layer can be primary carding under the action of the opening roller. The roller feeding device has the following three forms.

(1) The upper feeding roller is located on the top of the feeding plate. Under the action of feeding roller clothing, the cotton layer is tightly held, and then rises to the point of arc plate under the action of roller, and then it is combed, opened and rotated by the high-speed rotating opening roller with card clothing. Because the shape of the arc-shaped plate is an acute angle, the fiber has a great friction force at the acute angle of feeding and output, so it can have a good control force on the feeding fiber, so as to reduce the fuzzing phenomenon, and the damage to the fiber is small. This kind of feeding device is generally used for fibers with relatively fine raw materials, high requirements for fiber mesh, and fiber length > 51mm.

(2) The principle and mode of the down feeding device are basically the same as one, except that the curved plate is located above the roller, which has slight damage to the fiber. This device is widely used in spinning relatively short fibers, less than 51mm in length.

(3) roller holding type (as shown in Fig. 3) feeding, usually there is a pair or two pairs of rollers with needle clothing, which tightly hold the feeding cotton layer, so that the cotton layer will not produce irregular free under the action of the opening roller, but relatively speaking, this feeding mode has greater damage to the fiber. In addition, because the feeding roller and the opening roller are arranged in a zigzag pattern, there is inevitably a certain distance. When spinning short fibers, some fibers can not be effectively controlled, so there will be pilling phenomenon. Moreover, the lower feeding roller is easy to wrap the roller, which will affect the gripping force of the feeding roller, resulting in patchy clouds on the cotton web, and also easy to cause mechanical damage. This feeding method has been rarely used in high-speed and high-yield equipment.
