Characteristics of textile machinery
Another characteristic of textile machinery is the high repetition coefficient of the same part of each machine. Take spinning frame as an example. Each spinning frame has 400 spindles, and 400 same rings and spindles are required for spinning 400 yarns at the same time. As for the knitting machine, the number of stitches is even larger. Each high-speed warp knitting machine with a working range of 6.6m needs 7280 grooving needles. Machinery factories producing these parts need to design corresponding tools, fixtures, molds and even special multi-station automatic machine tools or special assembly lines according to the batch of parts to ensure the high efficiency, high quality and low cost of the production of these parts.
The complexity of textile machinery parts is also reflected in the types, because different processing objects need to design and manufacture different types of parts according to different raw materials such as cotton, hemp, wool, silk and chemical fiber. For example, wool spindles are larger in size than cotton spindles, but similar in structure. For another example, due to the diversity of fabric width, the same structure principle is required, but different working range is required. If the above parts and machine parameters are allowed to develop arbitrarily, it will have adverse effects on the product design efficiency, production management and production costs of the textile machinery factory, increase the workload of equipment management, spare parts storage, maintenance and replacement, and even cause confusion in factory management. The purpose of standardization is to take the main technical parameters that are as simple as possible and have appropriate numerical spacing distribution as the design basis for a group of machines with different capacities under the principle of meeting different process requirements. For example, the spinning machine is designed according to the spindle distance, the weaving machine and the printing and dyeing machine are designed according to the working range, and the knitting machine is designed according to the diameter of the needle cylinder.
