Description

Technical Field

[0001] The utility model relates to the technical field of air jet looms, in particular to an air intake structure of an air jet loom. Background Art

[0002] The air jet loom is a loom that uses air jets to insert the weft. It requires a beating-up mechanism when in use. There are many types of such beating-up mechanisms on the market today, which can basically meet people's needs, but there are still certain problems.

[0003] In the prior art, the air jet loom realizes warp feeding by means of air compressor compressed air which is diverted through air bag to various small nozzles. However, the air intake structure of the prior art cannot accurately adjust the air pressure in real time after the pressure is adjusted by the pressure regulating valve, and cannot be adjusted as needed, causing inconvenience during use. Utility Model Content

[0004] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides an air intake structure of an air jet loom.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an air intake structure of a jet loom, including an air filter, an air intake pipe is arranged at the left end of the air filter, the left end of the air intake pipe is connected with a five-way joint, the five-way joint is externally connected to a plurality of air compressors, the right end of the air filter is fixedly connected to a first air supply pipe, the end of the first air supply pipe is fixedly connected to a pressure regulating valve, the pressure regulating valve is externally connected to a second air supply pipe, and the second air supply pipe is externally connected to an air blowing mechanism.

[0006] Furthermore, each joint of the five-way joint is externally connected to a group of air pipes, the ends of the air pipes are connected to the air compressor, and the air pipes are provided with solenoid valves.

[0007] Furthermore, the blowing mechanism includes an air bag, an air delivery groove is provided inside the air bag, and the upper end of the air delivery groove is connected to a plurality of groups of main pipes.

[0008] Furthermore, the upper end of each group of the main pipe is fixedly connected to the three groups of branch pipes, the lower ends of the branch pipes are connected to the main pipe, and the upper ends of the branch pipes are fixedly connected to the gas needles.

[0009] Furthermore, the air needle is fixedly mounted on the air jet loom via a mounting plate.

[0010] The beneficial effect of the utility model is as follows: by first starting one of the air compressors, the air is adjusted to a certain pressure through the air filter and the first air supply pipe through the pressure regulating valve, and the pressure adjusted by the pressure regulating valve is kept unchanged. When the pressure needs to be adjusted, the other air compressors at the five-way joint are started. The pressures generated by the remaining four air compressors themselves are all different. Through permutations and combinations, the appropriate air compressor is turned on to adjust the pressure. This adjustment method is fast and efficient, with precise adjustment, and can be applied to different working conditions. Then the air flows through the second air supply pipe, the air delivery trough, the main pipe, and the branch pipe into the air needle, realizing the jet transport warp.
