Textile Machinery Industry How to Grind Knife and Cut Wood

What are the special basic parts in the textile machinery industry? From the product classification, some main varieties can be listed. In fiber production machinery, there are special booster pumps, delivery pumps, gear pumps, serpentine pumps, spinning (metering) pumps, oil pumps, spinning filters, spinnerets, spinnerets, planetary reducers and stepless transmissions for mechanical speed regulation, and setting rollers, crimping rollers, crimping knives, cutting knives, nozzles, speed increasing theories, false twisters, etc. for spinning and post-processing.

There are more kinds of special basic parts in fiber processing machinery, such as metal card cloth and elastic card cloth in fiber carding machinery, various rollers, rockers, roller bearings, spindles, steel collars, wire rings, needle comb rollers, spinning cups, rubber rollers, rubber rings, splicers, knotters, yarn clearer and metal trough tubes in fiber deep and fine processing equipment. Flat reed, profiled reed, main nozzle, auxiliary nozzle, rapier head, rapier belt, sword wheel, weft storage, heddle, heald, stop piece and stitch shaft in fiber manufacturing machinery. There are fiber weaving machinery knitting machinery in a variety of yarn feeder and a variety of knitting needles. Yarn fabric printing and dyeing and finishing machinery also has a lot of special basic parts. Such as all kinds of soft and hard rubber rollers, cloth guide rollers, drying cylinders, steam inlet heads, cloth clamps, chains, edge absorbers, expanders, nickel mesh, silk mesh, rubber guide belts for flat screen and round screen printing, nozzles for inkjet printing, and all kinds of scissors, flat knives and round knives in the finishing process. There are also many special basic parts, such as special motors and special control components.

Special basic parts are characterized by standardization, serialization and generalization in the industry, with the same variety name, but the shape, size, specification and use requirements are different and ever-changing. Another feature is that the production batch of the same variety is relatively large, in the organization of production, suitable for large-scale, streamlined production form, another feature is to have a high level of reliability, consistency and stability, so as to meet the general, interchangeable requirements. The basic parts are ready, no matter who produces the mainframe, it needs to be selected and matched.

It is very important for the industrial upgrading to do a good job in the special basic parts of textile machinery and improve the technical level of the special basic parts. The production of special basic parts for textile machinery in China has a certain foundation, the technical level has also been greatly improved, and gratifying results have been achieved. For example, Changzhou spinneret factory has mastered the precision micro-hole processing technology of 0.06mm or 0.07mm, and has mastered the processing technology of 67625 spinning holes, aperture of 0.07mm, aperture and hole spacing of 0.002mm, which no one in the world can solve. Chongqing Golden Cat Spinning Co., Ltd. has mastered the manufacturing technology of 33/10ESGC traveler, which weighs only a few tenths of a milligram and is used for spinning 300 yarns. Changzhou Blue Arrow Reed Company and Shaoxing Shuifu Reed Company have conducted in-depth research and analysis on the shape design of stainless steel reed pieces only 0.1mm thick, the geometry of the air flow channel, the surface coating and the bonding process of the reed, and have mastered the first-hand core technology.

There is a comparison to identify. In the face of the new technical requirements of the use of technology, in the face of international and domestic market competition challenges, but also to see our gap. From the import and export situation of textile machinery special basic parts in 2011, we can see our gap. In 2011, the quantity of similar special basic parts exported by China was 337 per cent of imports, while export earnings were only 59.2 per cent of imports, and the average unit price of imports was 592 per cent of the export unit price. The average import unit price of metal clothing is 330.8 per cent of the average export unit price. The knitting needles differ by a hundred times. The average unit price difference of the steel collar is also more than ten times.

The situation is developing, science and technology are advancing, and no one can stop the historical trend. How to make the special basic parts of textile machinery well, refined, bigger and stronger, there are many articles to do. If you can from the basic academic research, basic material selection, process technology control, seriously, carefully do, will soon change. If the foundation is laid, we will seek development in the market competition and contribute to the industrial upgrading
