How To Sharpen A Knife In The Textile Machinery Industry?

　　 Spin What are the basic parts in the machinery industry? From the classification of products, some main varieties can be listed.

In the fiber production machinery, there are special booster pumps, delivery pumps, gear pumps, spinning pumps, oil pumps, spinning filters, spinneret heads and spinneret plates. There are planetary reducer and continuously variable transmission for mechanical speed regulation. There are also shaping rolls, crimping rolls, crimping knives, cutting knives, nozzles, speed increasing theories and false twisters for spinning and post-processing.

There are more kinds of special base parts in fiber processing machinery, such as metal card clothing, elastic clothing, fiber machinery, various kinds of roller, cradle, roller bearing, spindle, steel collar, traveller, pin roller, spinning cup, rubber roller, apron and splicer, knotting device, yarn clearer and metal trough. Flat reeds, profiled reeds, main nozzles, auxiliary nozzles, rapier head, rapier belt, transfer wheel, weft feeder, heald wire, heald sheet, stop film and side support pin in fiber manufacturing machinery. There are also various kinds of yarn conveying devices and knitting needles in knitting machines.

There are also many special parts for textile dyeing and finishing machinery. For example, all kinds of soft and hard rubber rollers, guide roller, drying cylinder, steam inlet, cloth, chain, edge suction device, expander, flat screen, nickel screen, silk screen, rubber guide band, ink jet printing nozzle, and all kinds of scissors, flat knives and round knives in the finishing process. There are many special components, such as special motors and special control elements.

The characteristics of special base parts are standardization, serialization and generalization in the industry, with the same name, but different shapes, sizes, specifications and requirements. Another characteristic is that the production volume of the same species is relatively large, and in the form of mass production and pipelining production in the organization production, another characteristic is to have a high level of reliability, consistency and stability, so as to meet the requirements of general and interchangeability. The basic parts are ready, no matter who produces the mainframe, they need to be selected and used.

It is very important for industrial upgrading to do well in the basic parts of textile machinery. Our country's textile machinery specialized basic parts production has already had certain foundation, the technical level has also greatly improved, and achieved gratifying results. For example, Changzhou spinneret factory has mastered 0.06 millimeter or 0.07 millimeter precision micro hole processing technology, and has grasped the hub and spoke 67625 spinning holes, 0.07 millimeter diameter, and 0.002 mm hole diameter processing technology which no one can solve in the world. Chongqing golden cat spinning company has mastered the manufacturing technology of the 33/10ESGC type traveller, which is only a few milligrams of heavy weight, spinning 300 yarns. Changzhou blue arrow reed company and Shaoxing Shui Fu reed company have in-depth research and Analysis on the shape design, airflow channel geometry, surface coating and reed adhesion technology of the stainless steel reeds with only 0.1 mm thickness, and have mastered the first hand core technology.

There are comparisons. In the face of the new technological requirements of technology, we should also see our differences in the face of the competitive challenges of the two international and domestic markets. We can see our difference from the import and export situation of textile machinery special base parts in 2011. In 2011, the number of similar specialties in China's exports was 337% of imports, while foreign exchange earnings from exports amounted to only 59.2% of the total imports. The average unit price of imports was 592% of the export unit price. The average import price of metal clothing is 330.8% of the export unit price. Knitting needles are hundreds of times different. The average univalent difference of the steel collar is also more than ten times.

The situation is developing and technology is improving. No one can stop the tide of history. There is a lot to be done about how to make the basic parts of textile machinery well, do well, make it bigger and stronger. If we can learn from basic academic research, basic material selection, process technology control, conscientiously and meticulously, we will change quickly. "Sharpening the chopper is not a mistake". If the foundation is laid, it will develop in the market competition and contribute to the upgrading of the industry.
