Description
Technical Field
The invention relates to a density stabilizing device, in particular to a density stabilizing device of a computerized flat knitting machine.
Background
The textile industry is a labor intensive and externally dependent industry in China. China is the biggest textile garment production and export country in the world, and the continuous and stable growth of textile garment export is vital to ensuring China foreign exchange storage, international balance of collection and expenditure, stable Renminbi exchange rate and solving the sustainable development of social employment and textile industry. The raw materials of the textile mainly comprise cotton, cashmere, wool, silkworm cocoon silk, chemical fiber, feather and down, and the like. The downstream industries of the textile industry mainly comprise the clothing industry, household textiles, industrial textiles and the like. Ancient Chinese textile and printing and dyeing technology has a very long history, and ancient people have understood local materials, used natural resources as raw materials for textile and printing and dyeing and manufactured simple textile tools in order to adapt to climate change as early as the original society. Today, our everyday clothing, certain living goods and artwork are products of textile and printing and dyeing technology. In textile machines, computerized flat knitting machines are indispensable. The computerized flat knitting machine is a double-needle plate latch needle weft knitting machine, its cam device is like a group of plane cams, the stitch of the knitting needle can be fed into the channel of the cam, the cam can be moved, the knitting needle can be forced to make regular lifting movement in the needle channel of the needle plate, and the yarn can be knitted into knitted fabric by means of the action of needle hook and needle latch. In the ascending process of the knitting needle, the coil gradually withdraws from the needle hook, the needle latch is opened, and the withdrawing needle latch is hung on the needle rod; during the descending process of the knitting needle, the needle hook hooks the newly laid yarn and draws and bends the newly laid yarn into a coil, meanwhile, the original coil is separated from the needle hook, the new coil passes through the old coil and is connected with the old coil in series, and the coil strings knitted by a plurality of knitting needles are mutually connected to form the knitted fabric.
However, the density triangle of the existing computerized flat knitting machine has a relatively simple structure, when the knitting speed of a machine head is low, the density is not changed too much, within the design error range of the computerized flat knitting machine, along with the development of the technology of the computerized flat knitting machine, the knitting speed of the computerized flat knitting machine is faster and faster, a knitting needle presses downwards along the running track of the density triangle due to inertia generated by the self weight of the knitting needle at a high speed, so that a coil contacted with the knitting needle is enlarged to loose the density of a cloth piece, and the knitting fabric loosers at a higher speed, so that the problem that the length of two sides of the cloth piece is compared due to the high speed and the low speed of the machine head is solved.
