Technical Field
The invention relates to the technical field of textile machinery, in particular to a waxing device for cotton yarn spinning.
Background
The textile machinery is a production means and material basis of the textile industry, the technical level, quality and manufacturing cost of the textile machinery are directly related to the development of the textile industry, and the yarn waxing is to wrap yarns by using wax, so that the wax is attached to the yarns, the friction coefficient value of the surfaces of the yarns is reduced, the friction between the yarns is reduced, the unwinding of the yarns is facilitated, and the deterioration of yarn hairiness is reduced.
At present, yarn waxing is finished by the fact that a yarn contact wax block rotates around the axis, along with the reduction of the wax block, the pressure of the wax block on the yarn is reduced, the resistance which can be provided by the wax block is smaller and smaller, yarn waxing can become uneven, even the yarn waxing can not be finished, in addition, as the surface of the yarn is a circumferential curved surface, the curved surface of the yarn which is not in contact with the wax block can not be waxed, and therefore waxing is uneven, and the quality of textile products is seriously affected.
