Description

Technical Field

[0001] The utility model relates to the technical field of spinning machines, in particular to a waste discharging device for a spinner of a spinning machine. Background Technique

[0002] Air-jet spinning is a new type of spinning production method. The working principle of air-jet spinning is completely different from that of ring spinning. It actively feeds the sliver forward by the gripping of the feed roller and the feed plate, and is combed into single fibers by the combing roller. Since a vacuum is formed in the spinning cup, it forces the outside air to be supplemented from the air supply port and the yarn guiding tube, thereby carrying the combed single fibers through the cotton tube into the spinning cup to form a condensed sliver. When the yarn is led through the yarn guiding tube, it is sucked into the condensing groove and connected to the sliver. The centrifugal force generated by the high-speed rotation of the spinning cup makes the yarn tail of the yarn adhere to the surface of the condensing groove and is gripped and twisted into yarn, and then is led out through the anti-twist disc and the yarn guiding tube and wound into a bobbin.

[0003] Existing spinning machines are generally equipped with a waste discharging device. The waste discharging device includes a waste discharging port, a waste suction pipe and a waste discharging air duct. The waste discharging port is arranged on the cavity wall of the combing cavity. The waste suction inlet of the waste suction pipe is communicated with the waste discharging port, and the waste suction outlet of the waste suction pipe is communicated with the waste discharging air duct. The impurities are discharged into the waste discharging box at the tail of the vehicle from the waste discharging port, the waste suction pipe and the waste discharging air duct by the action of gravity separation and negative pressure environment. Since the movement trajectory of the impurities changes tortuously during the discharging process, and due to long-term work, the impurities will slowly adhere to the inner wall of the waste discharging pipe. Over time, the impurities in the waste discharging pipe will accumulate more and more, and finally the waste discharging pipe will be blocked, seriously causing the waste discharging pipe to fail to work normally, and the impurities will enter the rotor cup with the cotton fibers, affecting the normal spinning of the spinning machine.

[0004] After retrieval, the publication number CN213037910U discloses a waste discharging device for a spinner of a rotor spinning machine, belonging to the technical field of spinning machines. A waste discharging device for a spinner of a rotor spinning machine includes a main waste discharging pipe, a protective sleeve is sleeved on the outer surface of the main waste discharging pipe, a clamping groove is arranged inside the protective sleeve, a waste suction cotton strip is arranged inside the clamping groove, and a limiting groove is arranged inside the main waste discharging pipe; through the arrangement of the main waste discharging pipe, the protective sleeve and the locking collar, since each clamping groove in the protective sleeve is provided with a waste suction cotton strip, when it is necessary to replace the waste suction cotton strip, the staff can complete the replacement process by screwing the protective sleeve so that the new waste suction cotton strip slides into the limiting groove. When it is necessary to clean the protective sleeve and the main waste discharging pipe, the locking collar can be unscrewed from one side of the main waste discharging pipe to separate them. The overall operation process is simple and convenient, time-saving and labor-saving, and greatly improves the work efficiency of the staff.

[0005] In the above scheme, the arrangement of the waste suction cotton strip is adopted to realize the adsorption of impurities in the main waste discharging pipe. However, due to the limited impurity adsorption effect of the waste suction cotton strip, it is difficult to achieve a good waste discharging effect during the long-term accumulation of impurities on the inner wall of the main waste discharging pipe.

[0006] For this reason, a waste discharging device for a spinning device of a spinning machine is proposed, which has the advantages of preventing impurity adhesion and blockage, thereby solving the problems in the above-mentioned background technology. Utility Model Content

On both sides of each arc-shaped shell of the impurity turnover cylinder, connecting side strips are welded, and bolts are inserted through the surfaces of the connecting side strips. On the inner wall surface of each arc-shaped shell of the impurity turnover cylinder, a rubber adhesive sheet is installed. Two strip-shaped openings are formed on the surface of the main waste discharging pipe, and the two strip-shaped openings are respectively communicated with the two arc-shaped shells of the impurity turnover cylinder. A fan protective sleeve clamp is installed at the left end of the main waste discharging pipe, and a threaded ring is integrally formed at the tail of the fan protective sleeve clamp. A threaded groove is provided inside the left end port of the main waste discharging pipe corresponding to the threaded ring.

[0009] As a further description of the above technical solution: On the outer surface of each arc-shaped shell of the impurity turnover cylinder, an exhaust nozzle is provided, and a circular filter screen is installed at the port of the exhaust nozzle.

[0010] As a further description of the above technical solution: Two groups of limiting blocks are welded on the surface of the main waste discharging pipe, and the two groups of limiting blocks are respectively in contact with the end faces of the two arc-shaped shells of the impurity turnover cylinder.

[0011] As a further description of the above technical solution: The length of the arc-shaped shell is greater than the length of the strip-shaped opening, and a semi-circular opening is formed on the end face of the arc-shaped shell corresponding to the main waste discharging pipe.

[0013] As a further description of the above technical solution: Through holes are formed on the surface of the connecting side strip of the arc-shaped shell, and the aperture of the through hole is adapted to the diameter of the bolt.

[0014] The present utility model has the following beneficial effects:

[0015] In the present utility model, an impurity turnover cylinder composed of two arc-shaped shells is installed on the outer surface of the main impurity discharge pipe through bolts.

This maximally avoids the accumulation of impurities on the inner wall of the main impurity discharge pipe, thereby maintaining the smoothness of the main impurity discharge pipe. At the same time, since the two arc-shaped shells of the impurity turnover cylinder are connected by bolts, it is easy to separate the two arc-shaped shells, facilitating the cleaning of the impurity turnover cylinder. Since the main impurity discharge pipe and the blower protective sleeve clamp are connected by a threaded ring and a threaded groove, it is convenient to disassemble the main impurity discharge pipe, and it is easy to clean, replace, and maintain the main impurity discharge pipe.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] According to the embodiments of the present utility model, an impurity discharge device for a spinneret of a spinning machine is provided.

[0024] Now, the present utility model will be further described in conjunction with the accompanying drawings and specific embodiments. As Figures 1-4As shown in the figure, the impurity removal device of the spinning device of the spinning machine according to the embodiment of the present utility model includes a main impurity removal pipe 1. A impurity turnover cylinder 3 is sleeved and installed on the surface of the main impurity removal pipe 1, and the impurity turnover cylinder 3 is composed of two arc-shaped shells 4. Connecting edge strips 5 are welded on both sides of each arc-shaped shell 4 of the impurity turnover cylinder 3, and bolts 6 are inserted through the surface of the connecting edge strips 5. A rubber adhesive sheet 10 is installed on the inner wall surface of each arc-shaped shell 4 of the impurity turnover cylinder 3. Two strip-shaped openings 11 are provided on the surface of the main impurity removal pipe 1, and the two strip-shaped openings 11 are respectively communicated with the two arc-shaped shells 4 of the impurity turnover cylinder 3. A fan protection sleeve clamp 2 is installed at the left end of the main impurity removal pipe 1, and a threaded ring 9 is integrally formed at the tail of the fan protection sleeve clamp 2. A threaded groove 12 is provided corresponding to the threaded ring 9 on the inner side of the left end port of the main impurity removal pipe 1. Among them, the main impurity removal pipe 1 is connected to the fan by means of the fan protection sleeve clamp 2, and the end of the main impurity removal pipe 1 away from the fan protection sleeve clamp 2 is communicated with the impurity removal box;

[0025] In one embodiment, an exhaust nozzle 8 is provided on the outer surface of each arc-shaped shell 4 of the impurity turnover cylinder 3, and a circular filter screen is installed at the port of the exhaust nozzle 8. Through the setting of the exhaust nozzle 8, an air discharge port is given to the inside of the arc-shaped shell 4, which is conducive to the discharge of impurities in the main impurity removal pipe 1 and prevents impurities from accumulating on the inner wall of the main impurity removal pipe 1. The exhaust air volume of the exhaust nozzle 8 is much smaller than the negative pressure environment in the main impurity removal pipe 1, so that the setting of the exhaust nozzle 8 will not interfere with the normal impurity removal of the main impurity removal pipe 1. Among them, the exhaust nozzle 8 can also be sealed with a rubber cap and the rubber cap can be removed for use when the impurity adsorption is not smooth.

[0026] In one embodiment, two groups of limit blocks 7 are welded on the surface of the main impurity removal pipe 1, and the two groups of limit blocks 7 are respectively in contact with the end faces of the two arc-shaped shells 4 of the impurity turnover cylinder 3. Through the setting of the limit blocks 7, the installation position of the arc-shaped shell 4 is always corresponding to the strip-shaped opening 11, and the whole impurity turnover cylinder 3 is prevented from sliding on the surface of the main impurity removal pipe 1.

[0027] In one embodiment, the length of the arc-shaped shell 4 is greater than the length of the strip-shaped opening 11, and a semi-circular opening is provided on the end face of the arc-shaped shell 4 corresponding to the main impurity removal pipe 1. Through the setting of the semi-circular opening, it is easy to connect the arc-shaped shell 4 with the impurity removal branch pipe 1.

[0028] In one embodiment, the surface of the rubber adhesive sheet 10 facing away from the inner wall of the arc-shaped shell 4 is coated with an adhesive surface. Through the setting of the adhesive surface, it is easy to adhere impurities and prevent the impurities from falling back into the main impurity removal pipe 1 again.

[0029] In one embodiment, through holes are provided on the surface of the connecting edge strip 5 of the arc-shaped shell 4, and the aperture of the through holes is adapted to the diameter of the bolt 6. Through the setting of the through holes, it is easy to install the bolt 6, so that the two arc-shaped shells 4 of the impurity turnover cylinder 3 are detachable, which is conducive to the later cleaning of impurities.

[0030] Working principle:

[0031] During use, first, the fan operates to suck impurities into the interior of the impurity discharge main pipe 1. The impurities are discharged into the impurity discharge box communicated with the impurity discharge main pipe 1 by the action of gravity separation and the negative pressure environment. When the impurities adhere to the inner wall of the impurity discharge main pipe 1, the strip-shaped opening 11 formed on the surface of the impurity discharge main pipe 1 serves as the output port for the impurities, enabling the impurities to pass through the strip-shaped opening 11 and enter the two arc-shaped shells 4 of the impurity turnover cylinder 3, and causing the impurities to adhere to the surface of the rubber adhesive sheets 10 on the inner wall surfaces of the two arc-shaped shells 4, thus avoiding the accumulation of impurities on the inner wall of the impurity discharge main pipe 1 to the greatest extent and maintaining the smoothness of the impurity discharge main pipe 1. At the same time, since the two arc-shaped shells 4 of the impurity turnover cylinder 3 are connected by bolts 6, by removing the bolts 6 on the surface of the connecting edge strip 5, the separation of the two arc-shaped shells 4 is easy, facilitating the cleaning of the impurity turnover cylinder 3. Since the impurity discharge main pipe 1 and the fan protective sleeve clamp 2 are connected by a threaded ring 9 and a threaded groove 12, by rotating the impurity discharge main pipe 1, the impurity discharge main pipe 1 is separated from the fan protective sleeve clamp 2, facilitating the disassembly of the impurity discharge main pipe 1 and making it easy to clean, replace, and maintain the impurity discharge main pipe 1.
