Air supply for carding machine

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

The compression and air sources used in the development of the air-jet weft insertion mechanism of the carding machine have two types: collective air supply control system and individual air supply device. 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). 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.

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. The latter can be used flexibly, the operation is simple and convenient, and there is no relationship between the machines. Currently, it is widely used in my country, that is, each machine is equipped with compressor parts. The compressor combing action compresses a certain amount of air that is provided by the Pickup Survey Division each time it generates.

The compressor has the following requirements: (1) The function can be stable, and the basic parameters of the compressed air used for each weft insertion are the same. (2) The change of air supply and air pressure must meet the requirements of weft insertion. For a certain box cap, a certain amount of air is required to guide the weft yarn to the other side of the selvage. During the weft insertion process, the change of air pressure cannot be obtained, and it is very easy for excessive air pressure to reach the peak temperature and air velocity. Appears to untwist the weft yarn, and even blow the weft yarn.

(3) The compressed air must be clean and free of oil mist and dirt. Mooring gas adsorption on the pipe wall will increase the resistance of the z-rod of the pipe, contaminate the fabric, and cause defects. The common card feed device is a small single-acting reciprocating compressor with low pressure (Figure 9-34).

In each ring cycle of the large loom, the piston 4 goes back and forth once, and the gas constant is supplied. Therefore, the horizontal structure size of the loom has a greater impact. Therefore, for workshops with the same number of machines, the common cam type sword loom is smaller than the eccentric joint seed type sword loom, which can effectively save the enterprise plant infrastructure projects. invest.
