Description
Technical Field
The invention relates to the technical field of spinning equipment, in particular to an artificial intelligent double-row impurity carding device of a rotor spinning machine and application thereof.
Background
The rotor spinning machine has become the most mature spinning form with the widest application range and larger economic and social effects in the novel spinning. The rotor spinning machine mainly comprises a rotor, a false twisting disc, a yarn-withdrawing tube, a yarn-withdrawing roller, a fiber conveying channel, a cotton feeding roller, a carding roller, a trash discharging device and the like, wherein centrifugal force generated when the rotor rotates at a high speed is utilized to enable fibers transferred to the rotor from a carding cavity to be condensed to form strands (fiber rings), and the strands are twisted to form yarn strips. The working process of the rotor spinning machine can be summarized as follows: the cotton sliver is fed into the carding chamber in the shell uniformly because the cotton feeding roller is driven by the stepping motor to rotate, the carding rollers in the carding chamber rotate circumferentially at a high speed, the cotton sliver fed into the carding chamber is carded into single fiber by the high-speed rotating carding rollers, and the impurity removing device is used for removing impurities in the cotton sliver.
The rotor spinning machine can be divided into a self-exhaust type and an air exhaust type according to the difference between the formation and the drainage mode of negative pressure in a rotor. For the air suction type rotor spinning machine, the carding and impurity stripping modes mainly comprise two modes:
the first is the active gettering mode. The carding roller is vertically arranged, the impurity stripping direction and the horizontal plane are in a parallel state, the impurity removal is realized by completely depending on airflow high negative pressure suction, the effective impurity separation can be also realized on various raw materials with larger impurity content, and the application range is wider. However, this approach has the following drawbacks: on one hand, because the impurities can be stripped along the horizontal plane only by requiring higher gettering negative pressure, the number of the removed impurities is changed due to the tiny fluctuation of the gettering negative pressure, and the variation of a finished yarn thickness section is larger; on the other hand, there are disadvantages that the energy consumption of the apparatus is high and the gettering channel is easily clogged.
The second is to use the centrifugal force of impurities to carry out free impurity falling. The carding roller and a vertical surface are arranged at a certain included angle alpha (alpha is less than 90 degrees), the impurity stripping direction and a horizontal plane form an angle alpha, and the impurity removal is called as free impurity removal by means of the centrifugal force and gravity combined action generated under the driving of the high-speed rotation of the carding roller. This mode is longer toward rotor transport fibre transfer passageway for the fibre obtains abundant straightening, and it is better to become the yarn uniformity, and the energy consumption is low, nevertheless has following defect: in the impurity separation process, light impurities with light weight, such as short fibers and the like, are not thrown far during separation and are close to the fiber conveying area, and are easy to suck back to the carding cavity after being accumulated in the stripping area under the action of fiber conveying negative pressure airflow, so that the rolling and sucking back are generated. The higher the impurity content is, the more serious the phenomenon of turn-up and back suction is, leading to the increase of the yarn breakage rate and the quality reduction, and leading the mode to have poor adaptability to the regeneration raw materials with more short fiber impurities.
In summary, the way of combing and stripping impurities of the existing rotor spinning machine cannot achieve the purpose in the aspects of raw material adaptability, resultant yarn quality consistency, low energy consumption and the like, and aiming at the above dilemma of the existing spinning machine market, how to provide a spinning mode which can increase the raw material adaptability, ensure good resultant yarn quality consistency and reduce energy consumption is a technical problem which needs to be solved urgently at present.

As a typical example, the procedure of removing impurities by using the double impurity removing and carding device 100 may be as follows:
when the cotton sliver is fed into the carding cavity in the shell through the cotton sliver feeding channel, impurity information of the cotton sliver in the cotton sliver feeding channel is detected through the impurity detector, and a detection result is sent to the air spraying control device.
In the process that the cotton sliver fed into the carding cavity is carded by the carding roller rotating at a high speed, the air injection control device controls the air injection holes corresponding to the area where the impurities of the cotton sliver are located on the carding roller to inject air according to the detection result so as to improve the looseness of the cotton sliver in the area where the impurities are located; meanwhile, the carding cavity is supplied with air through the air supply channel, impurities form an impurity stripping channel comprising an effective fiber area, a turning and back-suction area and a free impurity falling area at the lower part of the carding roller through an impurity stripping surface, long fibers in the effective fiber area are kept in the carding cavity to participate in yarn formation, the impurities in the turning and back-suction area are sucked into the impurity suction channel through the impurity suction port and discharged, and the impurities in the free impurity falling area freely fall into the impurity discharge belt and are discharged.
In this embodiment, the suction pressure of the gettering passage connected to the gettering port 171 is adjustable. Preferably, for the area with a large amount of impurities in the cotton sliver, the air injection amount is increased by the air injection control device 190, and meanwhile, the suction pressure of the impurity suction channel can be increased to increase the negative pressure suction force of the impurity suction port 171 to the impurities in the turning back suction area.
According to the technical scheme provided by the embodiment, the impurity discharging area 160 of the carding cavity and the horizontal plane are arranged in a 65-degree downward inclination mode, and impurities are discharged under comprehensive acting forces of air injection blowing action of the air injection holes, centrifugal force of the carding roller, negative pressure suction force of the impurity suction port on the impurity stripping surface, self gravity of the impurities and the like.

For the middle turning back suction area 161b, the area is mainly composed of light impurities, short velvet and other impurities (because the air supply holding force of the carding, the air injection blowing force, the centrifugal force and the gravity are kept flat, the part of impurities are easy to be sucked back into the carding body, and accidental broken ends are caused). The gettering is mainly used for removing light impurities, short velvet and the like and preventing the light impurities, the short velvet and the like from being reversely absorbed back to the carding cavity after being rolled, so that the gettering negative pressure requirement is not high, and the low energy consumption is ensured. For the lower free impurity falling area 161c, the area is mainly composed of heavy impurities such as cotton neps, cotton seed hulls, short thread ends and the like, the unit volume weight is large, and the carding air supply supporting force is far smaller than the comprehensive acting force of air injection blast wind power, centrifugal force and gravity, so that the heavy impurities and the heavy impurities freely fall into an impurity discharging belt to be discharged. The scheme is particularly suitable for the regenerated raw materials with more impurity content, heavy impurities, large impurities and the like in the impurities are freely discharged by combing centrifugal force, light impurities, short fibers and the like in the impurities are transferred and removed by impurity absorption, impurity turning and reverse absorption in an impurity discharge area of a combing cavity are eliminated, effective fiber yarn formation is reserved to the maximum extent, accurate impurity removal is realized, high yield is guaranteed, nep broken ends caused by impurity turning and reverse absorption are reduced, and the spinning suitability of the regenerated raw materials is improved.

Specifically, the transmitter 81 is a polarized light source, and when the cotton sliver enters the cotton feeding roller through the cotton feeding horn, the polarized light of the polarized light source is irradiated on the cotton sliver and then received by the receiver 82, and when impurities exist on the cotton sliver, the impurities change the polarized light through anisotropy, so that the received information of the receiver 82 changes, and the receiver 82 sends the received information to the impurity evaluation unit 183 to assist in impurity judgment.
As a typical example, the emitter 81 may include a light emitting member 811 and a polarizer 812, the light emitting member 811 serves as a light source, and light emitted from the light emitting member 811 is converted into linearly, circularly or elliptically polarized light by the polarizer 812. When the polarized light is irradiated into the cotton fiber, the light is not changed, and when the polarized light is irradiated into the foreign matter (foreign matter such as plastic), the polarized light is changed due to the anisotropy of the foreign matter, and the change can be detected by the receiver 82. Specifically, the receiver 82 may include a light sensor 821 and a detector 822, the light sensor 821 may detect light and transmit a detected light signal to the detector 822, and the detector processes the light signal and then sends the processed light signal to the impurity evaluation unit 183 to assist in determining impurities. By way of example and not limitation, when polarized light is incident on cotton fibers, the light enters the light sensor 821 and is detected by it, as shown in FIG. 6; when polarized light impinges on the impurities in the sliver, the transmitted light is deflected such that the light cannot be detected by the light sensor 821, as shown in fig. 7, and the time from the disappearance of the light to the re-detection of the light, the sliver section is the impurity existence region (i.e. the region is the impurity existence region).
