Description

Technical Field

[0001] The present application relates to the technical field of textile machinery, and in particular to a flying waste collection system for a spun yarn warp knitting machine. Background Art

[0002] With the further promotion of fabrics produced by spun yarn warp knitting machines that are soft, moisture-absorbent and comfortable in the market, the market has shown a huge demand for spun yarn warp knitted fabrics.

[0003] As the weaving process of short-staple yarn warp knitted fabrics proceeds, the fiber hairiness increases and becomes entangled with each other or the flying fibers gather, which will inevitably cause the blockage of the yarn guide needle holes and the yarn breakage. It will also have an adverse effect on high-speed, high-precision motion mechanisms such as the comb bar lateral shift mechanism, resulting in changes in the lateral shift amount, affecting the weaving process and even causing damage to the mechanical structure. In order to avoid the blockage of the yarn guide needle holes, reduce yarn breakage and prevent accidents, the flying fibers and hairiness on the yarn guide needles, comb bars and main mechanical devices of the warp knitting machine should be cleaned in time.

[0004] At present, there are three main ways to clean the flying fibers of short-staple yarn warp knitting machines: (1) manual cleaning: the work of cleaning flying fibers mainly adopts a repetitive mechanical working mode of "working - stopping - manual cleaning", and this mode has the problem of slow cleaning efficiency; (2) blowing cleaning: installing a blowing device on the overall structure of the warp knitting machine to clean the yarns in key parts such as the warp knitting machine's looping, yarn feeding, and combing bar transverse movement mechanism, but it will lead to the deterioration of the weaving environment and the reduction of fabric quality; (3) suction cleaning: installing a suction device around the entire warp knitting machine, but it has the problems of low efficiency and high energy consumption.

[0005] In view of the fact that the above-mentioned existing flying waste collection systems are not ideal, the present application proposes a flying waste collection system for staple yarn warp knitting machines based on the principle of suction negative pressure. The suction negative pressure flying waste collection system can utilize negative pressure to collect the flying waste of staple yarn in the production practice and put it into the flying waste collector, thereby avoiding the problems of low efficiency of manual cleaning of flying waste, deterioration of the weaving process of blowing and cleaning, and high energy consumption of ordinary suction and cleaning.

[0063] Among them, the fly collecting licker-in roller 4, the fly transferring licker-in roller 5, the fly stripping licker-in roller 6 and the scraper 7 are all parallel to each other, and the fly collecting licker-in roller hook needle 41 and the fly transferring licker-in roller hook needle 51 are needles with hooks that can hook the fly, while the fly stripping licker-in roller hook needle 61 and the scraper needle 71 are straight needles without hooks, and the scraper needle 71 is used to scrape off the fly remaining on the fly stripping licker-in roller hook needle 61. In addition, during the rotation of the fly collecting licker-in roller 4, the fly transferring licker-in roller 5 and the fly stripping licker-in roller 6, the needle tip linear speed of the fly stripping licker-in roller hook needle 61 is higher than the needle tip linear speed of the fly transferring licker-in roller hook needle 51, and the needle tip linear speed of the fly transferring licker-in roller hook needle 51 is higher than the needle tip linear speed of the fly collecting licker-in roller hook needle 41. Such needle tip surface linear speed setting is conducive to increasing the fiber transfer efficiency, avoiding fiber breakage and entanglement during the transfer process, and protecting the hook needle.

[0064] Optionally, see Figure 1 A metal adsorber 3 is also provided at the output end of the flying flower conveying pipeline 2, which is mainly composed of a magnet and is used to further filter the magnetic metal substances in the flying flowers.

This arrangement helps to reduce the blockage of the micropores in the storage compartment filter 81 by the flying petals and improve the collection efficiency.

[0067] In the embodiment of the present application, the storage cabin air pressure control valve 82 and the storage cabin fan 14 are used to ensure the stability of the air pressure and the smooth stripping and collection of the fly waste when clearing the fly waste storage cabin 8, thereby ensuring the normal operation of the fly waste collection system of the short-fiber yarn warp knitting machine. Another function of the storage cabin air pressure control valve 82 is to prevent gas from flowing into the input end of the fly waste storage cabin 8 when clearing the fly waste from the fly waste storage cabin 8.

[0068] For further information, see Figure 1 A dust absorber 10 is provided at the output end of the gas communication pipeline 9; a fan air pressure control valve 11 is provided at the input end of the main fan 12.

[0069] In the embodiment of the present application, the fan air pressure control valve 11 is mainly used to control the size of the airflow of the main fan 12 in the entire system through the degree of opening and closing; the dust adsorber 10 is mainly used to filter the dust and short fibers produced after breakage in the gas passing through the gas connecting pipe 9, and it is mainly made of non-woven filter material and processed paper filter material with micropores.

[0070] Next, the working principle of a flying waste collection system for a spun yarn warp knitting machine involved in an embodiment of the present application is explained.

[0071] The main fan 12 and the storage cabin fan 14 are started, and the yarn guide needle suction nozzle 101 and the knitting needle suction nozzle 105 in the suction negative pressure module 1 are used to respectively absorb the flying waste generated by the friction between the spun yarn and the yarn guide needle 16 of the spun yarn warp knitting machine during the yarn guiding process, and the flying waste generated by the knitting needle 17 of the spun yarn warp knitting machine during the weaving process due to the bending of the yarn, the mutual interlacing, and the friction between the machine parts and the knitting needle 17, and use the negative pressure to absorb them to the flying waste conveying device. In the pipeline 2, the fly flowers in the fly flower conveying pipeline 2 flow into the fly flower collecting licker-in roller 4 under the action of negative pressure, and the fly flowers sent into the air in the fly flower conveying pipeline 2 are hooked by the fly flower collecting licker-in roller 4, thereby completing the collection of fly flowers. Further, under the action of the fly flower transfer licker-in roller, the fly flowers collected on the fly flower collecting licker-in roller 4 are transferred to the fly flower stripping licker-in roller 6, and under the suction action of the storage cabin fan 14, the fly flower stripping licker-in roller 6 strips the fly flowers and drops them into the fly flower storage cabin 8. A part of the airflow passes through a plurality of rows of fly flower collecting licker-in roller through holes 42 and is discharged into the gas communication pipeline 9 from the fly flower collecting licker-in roller connection port 43, and another part of the airflow is discharged into the fly flower storage cabin 8 along the fly flower stripping pipeline 21 under the action of the storage cabin fan 14, and then discharged into the gas communication pipeline 9 from the air outlet of the fly flower storage cabin 8, and finally discharged from the exhaust port 13.

[0072] In summary, when the main fan is in operation, the flying waste collection system of the spun yarn warp knitting machine, by setting the yarn guide needle suction nozzle and the knitting needle suction nozzle in the suction negative pressure module, respectively absorbs the flying waste generated by the friction between the spun yarn and the yarn guide needle during the yarn guiding process of the spun yarn warp knitting machine, and the flying waste generated by the bending of the yarn, the mutual interlocking, and the friction between the machine parts and the knitting needles during the weaving process of the spun yarn warp knitting machine, into the flying waste conveying pipeline by using negative pressure, and then the flying waste is collected into the flying waste storage cabin through the cooperation of the flying waste collection licker-in roller, the flying waste transfer licker-in roller and the flying waste stripping licker-in roller in the flying waste stripping pipeline, and the airflow is discharged from the exhaust port after passing through the gas connecting pipeline. Targeted local high-efficiency collection and cleaning of flying waste is achieved, and the problems of low efficiency of manual cleaning of flying waste, deterioration of the weaving link of blowing and cleaning, and high energy consumption of ordinary suction and cleaning systems are solved.
