Pre-wetting sizing mechanism

Abstract

The invention provides a pre-wetting sizing mechanism. An electric heater is fixedly arranged at the bottom of a pre-wetting tank and capable of heating water in the pre-wetting tank and keeping the water temperature constant so as to guarantee uniformity in sizing ratio. Meanwhile, yarn is threaded by coordination of an upper pressure roller, a lower pressure roller, an immersing roller and three drawing rollers to be immersed, size can permeate into the yarn fully and beneficially during sizing, and sizing effect is improved effectively. Rotating shafts of the upper pressure roller are fixed on two sides of the pre-wetting tank through supports at two ends, a cylinder is arranged at the tops of the supports, a piston shaft of the cylinder is fixedly connected with the rotating shafts, the upper pressure roller moves up and down in the direction of the supports, automatic control on the upper pressure roller is realized, yarn feeding speed is regulated automatically, and meanwhile, daily maintenance and repair of a sizing machine are facilitated. The pre-wetting sizing mechanism further comprises a liquid level alarm device, when the pre-wetting tank is not full of water or the water is below warning value, water addition information is transmitted to operators through an audible and visual alarm, and the yarn is prevented from being sized non-uniformly due to insufficient immersion.

Description

technical field [0001] The invention relates to textile production automation equipment, in particular to a pre-wet sizing mechanism. Background technique [0002] The original meaning of textile is taken from the general term of spinning and weaving, but with the continuous development and improvement of the textile knowledge system and subject system, especially after the emergence of non-woven textile materials and three-dimensional composite weaving technologies, textile is not only the traditional spinning and weaving Weaving also includes non-woven fabric technology, three-dimensional weaving technology, electrostatic nano-netting technology, etc. Therefore, modern textile refers to a multi-scale structure processing technology of fibers or fiber aggregates. Ancient Chinese textile and printing and dyeing technology has a very long history. As early as in the primitive society, in order to adapt to climate change, the ancients knew how to use local materials, use n...

Problems solved by technology

The purpose of sizing is to prevent or reduce yarn breakage during weaving, to increase yarn strength, reduce yarn hairiness, and reduce friction between yarn and loom. However, manual sizing is used for transmission sizing, that is, yarn Immerse in the size, and then take it out to dry. This method has low production efficiency; the existing sizing machine can only enter the yarn into the size tank in a dry state, which will affect the penetration of the yarn by the size, and may cause Sizing on the surface of the yarn leads to insufficient sizing rate, poor sizing effect, and waste of sizing
