Description

AI impurity removing and carding method and system of rotor spinning machine

Technical Field

The invention relates to the technical field of intelligent spinning equipment, in particular to an AI impurity removing and carding method and system of a rotor spinning machine.

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. Various impurities such as polypropylene fiber, hair and 'three-filament' are often generated in the spinning process, the quality of the product produced by raw materials is greatly reduced due to the generation of the impurities, and therefore impurities in cotton slivers need to be removed in the spinning process.

At present, in the air suction type rotor spinning machine on the market, the carding and impurity stripping have two modes: the first is to use the centrifugal force of impurities to fall impurities freely. 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. The mode is longer to carry fibre transfer passageway toward the revolving cup for the fibre obtains abundant straightening, and the resultant yarn uniformity is better, and the energy consumption is low. The second is an active gettering method. 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, the existing impurity removal scheme has the following defects:

1) when the free impurity falling mode is adopted, in the impurity separation process, light impurities with light weight, such as short fibers, are not thrown far away when being separated, are close to the fiber conveying area, are easy to be sucked back to the carding cavity after being accumulated in the stripping area under the action of fiber conveying negative pressure airflow, and are rolled and sucked back, so that the yarn breakage rate is increased, and the adaptability to regeneration raw materials with more short fibers and impurities is poor. When an active impurity suction mode is adopted, the impurities can be stripped along the horizontal plane only by requiring higher impurity suction negative pressure, and the number of the removed impurities is changed due to fine fluctuation of the impurity suction negative pressure, so that the variation of the thickness of finished yarns is larger; but also has the disadvantages of high energy consumption of the equipment and easy blockage of the gettering channel. That is to say, the existing rotor spinning machine carding and impurity stripping mode can not realize the complete improvement in the aspects of raw material adaptability, yarn quality consistency, low energy consumption and the like.

2) Regardless of free impurity falling or active impurity absorption, all cotton slivers entering the carding cavity are subjected to impurity removal and carding based on the same impurity removal process, and the impurity removal process cannot be adaptively adjusted according to the impurity characteristics of the cotton sliver raw materials. In fact, the impurities are not uniformly distributed on the cotton sliver, and the impurities on some cotton slivers are smaller, such as small particle impurities like short fiber, tiny dust and the like, which belong to light impurities, and the impurities on some cotton slivers are larger in mass, such as neps, cotton seeds and plastic blocks, which belong to heavy impurities. Due to the self physical characteristics of the light impurities such as short fibers and the heavy impurities, different physical sites can be generated during impurity removal, for example, the light impurities such as the short fibers are easy to roll over in an impurity removal area and are sucked back into the carding body, so that the spinning quality is influenced.

How to provide a technical scheme for intelligently removing impurities and carding according to the impurity type characteristics of cotton slivers based on the characteristics of different impurity types is a technical problem which needs to be solved at present. Further, how to consider raw material adaptability, yarn quality consistency and low energy consumption is also a technical problem which needs to be solved urgently at present.

The discharge needle can be manufactured by using a high-aspect-ratio dry etching process on a silicon substrate material and electroplating metal copper on both sides. Because the size of the tail end of the discharge needle is in the micron order and the metal distances of the two sides are very close, a high-voltage discharge effect can be formed at the tail end of the discharge needle only by using a low-power supply, effective corona discharge is formed in the cavity of the discharge cavity, the discharge needle is vertically arranged in the middle of the cavity of the discharge cavity, and sufficient net charges are released under the excitation of voltage.

In use, by way of example and not limitation, under the control of a controller, negative charge substances are excited by an electrostatic generator and are discharged outwards through an opening on the impurity stripping surface, a charge release area is formed in a turning and back suction area of the impurity stripping surface, impurities adsorb net charge substances to form charged impurities when passing through the charge release area, and the charged impurities are sucked into the impurity sucking channel through the impurity sucking port and then discharged when moving towards the impurity sucking port under the action of the electric field adsorption force (electric field force generated by opposite charges) of the traction area.

Referring to fig. 7, in an embodiment of the present embodiment, the traction electrode of the traction area 190 may include a metal pole piece 191 and an energizing circuit 192, the energizing circuit 192 may be connected to a controller 193, and the energizing and de-energizing of the energizing circuit 192 may be controlled by the controller 193. When the power line 192 is energized, the metal plate 191 forms an electrode opposite to the foregoing net charge material, so that the charged impurities are subjected to a downward electric field force, and the charged impurities move toward the traction area under the action of the electric field force.

The metal pole piece can be made of metal aluminum foil, for example. By way of example and not limitation, for example, a discharge electrode of the electrostatic generator is excited by a high voltage to release electrons, the excited electrons are discharged corresponding to the rolling suck-back region, and negatively charged impurities are formed after encountering impurities in the rolling suck-back region; and the aluminum foil of the traction electrode is electrified to form a positive electrode, negatively charged impurities in the roll-over reverse suction area are attracted to move to the position of the aluminum foil, and when the negatively charged impurities pass through the impurity suction port, the negatively charged impurities are sucked into the impurity suction channel through the impurity suction port and then are discharged.

In another embodiment, the pulling region 190 employs a pulling electret as the charge-adsorbing structure. Specifically, the pulling electret is an electret having a counter electrode, and a charge property opposite to the excited net charge substance is formed by the electret, so that charged impurities are adsorbed and move in the direction toward the pulling region.

This approach creates an opposite charge attribute to the aforementioned net charge species in the traction zone 190 by utilizing the long-term stored charge characteristics of the electret, causing the net charge species to move toward the traction zone 190, thus eliminating the need for a further electrical path.

According to the technical scheme provided by the embodiment, the impurity discharging area 160 of the carding chamber and the horizontal plane are arranged in a 65-degree downward inclination manner, and impurities are discharged under the comprehensive acting forces of centrifugal force of the carding roller 120, negative pressure suction force of an impurity suction port on an impurity stripping surface, self gravity of the impurities and the like. Referring to fig. 7, for the uppermost effective fiber area 161a, the fiber length and the unit volume weight are small, and the air supporting force of the carding is larger than the combined acting force of the centrifugal force and the gravity, so that the limited fibers are kept in the carding cavity to participate in yarn formation. For the middle turning back suction area 161b, the area is mainly composed of light impurities, short velvet and other impurities (because the carding air supply holding force, the centrifugal force and the gravity are kept flat, part of the 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 and the like and preventing the light impurities 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. On the other hand, the characteristic that light impurities such as short fibers and the like are easy to obtain electric charges to form charged impurities for capturing is also utilized, a charge releasing area and a traction area are arranged in the impurity stripping channel, and the static generator of the charge releasing area releases net charge substances to charge the light impurities in the rolling and back-suction area; the traction area is arranged below the impurity suction port, the traction area is provided with a traction electrode or a traction electret to adsorb charged impurities and move towards the direction of the traction area, and when the moving charged impurities approach the impurity suction port, the impurity suction port sucks the charged impurities into the impurity suction channel, so that the impurity suction port is assisted to accurately suck the light impurities, and the impurity removal effect of the light impurities is improved. For the lower free impurity falling area 161c, the area is mainly heavy impurities such as neps, cottonseed 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 centrifugal force and gravity, so that the heavy impurities and the large 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.

Considering that the upper surface of the traction area is more or less accumulated with some charged impurities, the traction area can also comprise a impurity catching screen plate, and the screen plate is provided with meshes for heavy impurities to enter the free-fall impurity area. Furthermore, the impurity catching screen plate is also provided with a cleaning brush through a transverse moving mechanism, the cleaning brush is driven by the transverse moving mechanism to clean the charged impurities caught on the impurity catching screen plate towards the direction of the impurity suction port, and the charged impurities are sucked into the impurity suction channel under the suction negative pressure of the impurity suction port.

The conductive area corresponding to the traction area and the discharge area of the electrostatic generator can be further provided with an isolation protective layer to prevent workers from mistakenly touching the conductive area and the discharge area to cause injury. Preferably, the isolation protection layer is of a grid-shaped or comb-shaped structure, and is preferably made of rubber, silica gel, plastics and other materials.

In this embodiment, the impurity suction port, the impurity suction channel and the impurity discharge area of the carding cavity can be assembled by splicing after being manufactured separately, or can be manufactured by integral molding. Preferably, the impurity suction port, the impurity suction channel and the impurity discharge area of the carding cavity are integrally formed. The front end of the gettering channel 172 is connected to the gettering port 171, or the gettering port 171 is provided as a part of the front end of the gettering channel 172.

With continued reference to fig. 7, the gettering channels 172 are preferably L-shaped channels with rounded inner corners. The tail of the gettering channel 172 is communicated with a gettering main air pipe through a suction pipe 173. The cross section of the suction pipe 173 is circular, the tail end of the suction pipe 173 is provided with a tapered tail pipe with a gradually reduced caliber, and the small-caliber end of the tapered tail pipe is communicated with the impurity absorption main air pipe.

Specifically, the gettering pathway 172 may include a front suction port (connected to or as a gettering port) and a rear suction hole that are perpendicular to each other. The front suction port is rectangular and matched with the front suction port to form a rectangular through groove for allowing foreign particles to enter. The through hole is formed in the rear suction hole and can be connected with the suction pipe 173 in an inserting mode, the through hole is preferably set to be circular, dead angles cannot be formed, and impurities cannot stop easily. Preferably, one side surface of the rectangular through groove is set to be an inclined surface, a certain angle a is formed between the inclined surface and the outer side surface of the front suction port, a is larger than or equal to 60 degrees at an angle of 8 degrees, impurities can enter the through hole more smoothly through the rectangular through groove, an opening is formed in the inclined surface facing outwards at one end surface of the through hole, dead angles formed in the area by airflow are avoided, and impurity retention is avoided. And rounding treatment is carried out from the intersection of the rectangular through groove and the circular through hole, so that smooth transition is realized.

Preferably, the corresponding gettering port 171 or gettering channel 172 may also be provided with an air blowing device 174, as shown in fig. 7. In one embodiment, the blowing device 174 can be used to periodically blow clean the gettering port or the gettering passage to prevent the clogging of the gettering line. In another embodiment, the suction port or the suction passage may be cleaned by blowing air through the air blowing device 174 according to the operation of the user, so as to prevent the clogging of the suction line.
