Intelligent spinning device and system of rotor spinning machine

Abstract

The invention provides an intelligent spinning device and system of a rotor spinning machine, and relates to the technical field of intelligent spinning equipment. The intelligent spinning device comprises a cotton sliver feeding mechanism and an impurity discharging and carding mechanism. A charge release area and a traction area are arranged in an impurity removal area of a carding cavity, a charge adsorption instruction is triggered when cotton sliver impurities are detected to be light impurities through an impurity detector, so that the light impurities passing through the charge release area are electrified, the electrified impurities are pulled to move through the traction area, and the electrified impurities are sucked away by an impurity suction opening when passing through the impurity suction opening; the sliver feeding mechanism comprises a sliver guide device and a feeding roller, a sliver self-transmission mechanism is arranged corresponding to the sliver feeding mechanism, and the sliver self-transmission mechanism comprises an outer circulation traction structure which is connected with an inner circulation traction structure of the can conveying mechanism to form a closed-loop sliver conveying structure so as to convey slivers on the cans into a channel of the sliver guide device. Intelligent impurity removal based on the cotton sliver impurity type is achieved, and meanwhile automation, continuity and intelligence of spinning equipment are improved.

Description

technical field [0001] The invention relates to the technical field of intelligent spinning equipment, in particular to an intelligent spinning device and system of a rotor spinning machine. Background technique [0002] The rotor spinning machine has become the spinning form with the most mature technology, the widest application and the greater economic and social effect among the new types of spinning. In the process of spinning, various kinds of sundries often appear, such as polypropylene yarn, hair and "three silks", etc. The appearance of these sundries greatly reduces the quality of products produced from raw materials, so the spinning process needs to be carried out. Draining to remove impurities in the sliver. [0003] At present, there are two ways to comb and strip impurities in the suction rotor spinning machine on the market: the first is to use the centrifugal force of impurities to freely drop impurities. Usually, the opening roller is arranged at a certain...

Problems solved by technology

[0005] 1) When the free-falling method is adopted, during the separation process of impurities, light impurities such as short fluff and other light impurities are not far away during separation, and they are closer to the fiber conveying area. After the area is accumulated, it will be sucked back into the carding cavity, resulting in turning and sucking back, resulting in an increase in the yarn breakage rate, and poor adaptability to recycled raw materials with more short-pile impurities

When the active gettering method is adopted, a relatively high gettering negative pressure is required to strip the impurities along the horizontal direction, and small fluctuations in the gettering negative pressure will lead to changes in the number of excluded impurities, which in turn will cause large variations in the thickness and details of the yarn; and There are also disadvantages of high energy consumption of equipment and easy blockage of getter channels

That is to say, the existing method of combing and stripping impurities in rotor spinning machines cannot achieve comprehensiveness in terms of raw material adaptability, consistent yarn quality, and low energy consumption.

[0006] 2) Regardless of whether it is free falling or active suction, all the slivers entering the carding chamber are discharged and carded based on the same waste removal process, and the waste removal process cannot be based on the impurity characteristics of the raw material of the sliver—such as Impurity distribution area, impurity type characteristics, etc. - adaptive adjustment

However, the existing can handling vehicles are usually only responsible for the handling of cans, and often cannot automatically carry out sliver delivery (feeding)
