Description

Technical Field

[0001] The utility model belongs to the technical field related to spinning, and particularly relates to a spinneret cleaning device for synthetic fiber production. Background Art

[0002] The spinneret is also called the spinning cap. The function of the spinneret is to transform the viscous polymer melt or solution into a thin stream with a specific cross-section through the micropores, and solidify it into a filament through a coagulation medium such as air or a coagulation bath. The spinneret can be divided into a melt spinning spinneret (whose shape is round, rectangular, and fan-shaped) and a wet spinning spinneret (also called a spinneret cap). The spinneret needs to be cleaned after long-term use, but the current cleaning method still has the following disadvantages:

[0003] If the spinneret micropores are not cleaned thoroughly, it will lead to a high rate of broken wires, changes in the cross-section of the wires, unstable mechanical properties, etc. Therefore, it is particularly important to ensure that the spinneret micropores are clean, and an efficient spinneret cleaning device is an important guarantee to ensure the spinneret is clean; especially for disc-shaped spinnerets, the current direct flushing method cannot guarantee that the spinneret is completely cleaned;

[0004] Secondly, for a rectangular spinneret, it is necessary to clean it within a very long stroke, and the in-situ rotary cleaning cannot meet the need and is less practical. Utility Model Content

[0009] Furthermore, a screw rod is rotatably connected in the track, a motor 1 is fixed to one end of the track, and an output shaft of the motor 1 passes through the end of the track and is fixedly connected to the end of the screw rod.

[0010] Furthermore, the slider is in an I-shaped structure as a whole, and the upper part of the slider extends out of the upper end of the track, and the middle part of the slider is threadedly connected to the screw rod in a through-type manner.

[0011] Furthermore, an extension plate is fixed to one side of the upper portion of the slider, and a second motor is fixed to the bottom of the extension plate and is located on one side of the track, and an output shaft of the second motor passes through the extension plate upward and is fixed to a main gear.

[0012] Furthermore, a slave gear is fixed to the outer periphery of the rotating shaft, and the main gear and the slave gear are meshingly connected, and the inner diameter of the main gear is smaller than the inner diameter of the slave gear.

[0013] Furthermore, legs are fixed at both ends of the bottom of the spray frame, and a spinneret is placed on the spray frame, and the spinneret is located between the first cleaning pipe and the second cleaning pipe.

[0014] Furthermore, a hose is fixed to one end of the nozzle.

[0015] The utility model has the following beneficial effects:

[0016] The utility model solves the problem that conventional cleaning methods cannot ensure that the spinneret is clean by arranging a rotating shaft, an eccentric wheel, a nozzle, a cleaning pipe one, a cleaning pipe two, a nozzle, and a branch pipe; the spinneret to be cleaned is placed between the cleaning pipe one and the cleaning pipe two, and cleaning water from the outside is introduced by the nozzle, and is sprayed out through the cleaning pipe one and the cleaning pipe two through the nozzle, so that dirt on the upper and lower surfaces of the spinneret and the spinneret holes are cleaned at the same time. At the same time, the rotating shaft rotates, driving the eccentric wheel to rotate, so that the nozzle connected to the upper part of the eccentric wheel through the shaft rod rotates eccentrically, thereby causing the cleaning pipe one and the cleaning pipe two to rotate eccentrically, so that all surfaces of the spinneret are completely covered, the cleaning surface is increased, and a comprehensive cleaning operation is realized, the cleaning quality of the spinneret is improved, and the operation efficiency and operation quality of cleaning the spinneret are guaranteed.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figure 1-4As shown, the utility model is a spinneret cleaning device for synthetic fiber production, comprising a spray frame 1, a nozzle 2, a branch pipe 3, a linear guide rail 4 and an extension plate 6, both sides of the spray frame 1 are provided with linear guide rails 4, the nozzle 2 is located above the spray frame 1 and the linear guide rail 4, a U-shaped branch pipe 3 is fixedly passed through the outside of the nozzle 2, and the branch pipe 3 surrounds the outside of the spray frame 1, and a cleaning pipe 2 301 distributed evenly is fixedly passed through the horizontal part of the branch pipe 3, and a cleaning pipe 1 201 distributed evenly is fixedly disposed at a position on the nozzle 2 opposite to the horizontal part of the branch pipe 3, and a nozzle 5 is fixedly disposed at one end of the cleaning pipe 1 201 and the cleaning pipe 2 301;

[0027] The spray rack 1 is mainly used for placing the spinneret, and the nozzle 2 is used as the main cleaning and delivery pipeline to input the water used for cleaning. The water in the nozzle 2 is input into the branch pipe 3 and the cleaning pipe 1 201, and the water in the branch pipe 3 will also enter the cleaning pipe 2 301. In this state, the water in the cleaning pipe 1 201 and the cleaning pipe 2 301 will be sprayed out through the nozzle 5 to clean the spinneret placed on the spray rack 1;

[0028] The linear guide 4 includes a track 401 and a slider 404 slidably arranged in the track 401. The upper end surface of the slider 404 is rotatably connected to the rotating shaft 7. An eccentric wheel 701 is fixed to the upper end of the rotating shaft 7, and a shaft 7011 is fixed to the eccentric wheel 701. Ear plates 203 are also fixed to the outside of the nozzles 2 on both sides of the branch pipe 3. The bottom of the ear plate 203 is rotatably connected to the shaft 7011 located below it.

[0029] By using the slider 404 as a carrier, when the rotating shaft 7 on the upper part rotates, the eccentric wheel 701 is driven to rotate, and the eccentric wheel 701 will rotate with the shaft 7011. Because the shaft 7011 is not at the center of the eccentric wheel 701, the ear plate 203 and the nozzle 2 fixed on the ear plate 203 will rotate eccentrically, so that the cleaning tube 1 201 and the cleaning tube 2 301 can be used to clean the spinneret more conveniently.

[0030] A screw rod 402 is rotatably connected in the track 401, a motor 403 is fixed to one end of the track 401, and an output shaft of the motor 403 passes through the end of the track 401 and is fixedly connected to the end of the screw rod 402;

[0031] The slider 404 is in an I-shaped structure as a whole, and the upper part of the slider 404 extends out of the upper end of the track 401, and the middle part of the slider 404 is threadedly connected with the screw rod 402;

[0032] The motor 403 at the end of the track 401 works to drive the screw 402 to rotate. After the screw 402 rotates, the lower middle part of the slider 404 is located in the inner cavity of the track 401 and is limited, so it can only move in a straight line. When the slider 404 moves in a straight line, the structure above it will also move in a straight line.

[0033] An extension plate 6 is fixed to one side of the upper part of the slider 404, and a second motor 601 is fixed to the bottom of the extension plate 6 and is located on one side of the track 401. The output shaft of the second motor 601 passes through the extension plate 6 upward and is fixed to a main gear 602.

[0034] The extension plate 6 extends outward from the track 401 , and a second motor 601 is auxiliary installed at the bottom thereof. When the second motor 601 is working, it can drive the main gear 602 to rotate.

[0035] A slave gear 702 is fixed to the outer periphery of the rotating shaft 7, and the main gear 602 and the slave gear 702 are meshed and connected, and the inner diameter of the main gear 602 is smaller than the inner diameter of the slave gear 702;

[0036] When the main gear 602 rotates, it can mesh with the transmission gear 702 to rotate. The rotation of the gear 702 causes the shaft 7 to rotate. The rotation of the shaft 7 drives the eccentric wheel 701 to rotate. The difference in inner diameters enables the main gear 602 and the slave gear 702 to form a speed reduction structure.

[0037] Legs 101 are fixed at both ends of the bottom of the spray frame 1, and a spinneret is placed on the spray frame 1, and the spinneret is located between the cleaning pipe 1 201 and the cleaning pipe 2 301;

[0038] The spray frame 1 is supported by the legs 101, and a spinneret is placed on the spray frame 1 between the cleaning pipe 1 201 and the cleaning pipe 2 301, so that the nozzle 5 can be directly aligned with the spinneret for flushing.

[0039] A hose 202 is fixed to one end of the spray pipe 2; the hose 202 is connected to external cleaning water for transportation.

[0040] The specific working principle of the utility model is as follows: first, a spinneret (circular or fan-shaped) is placed on the spray rack 1 and placed between the cleaning pipe 1 201 and the cleaning pipe 2 301, and then the hose 202 is connected to the external cleaning water for transportation, and enters the spray pipe 2, and the water in the spray pipe 2 is input into the branch pipe 3 and the cleaning pipe 1 201, and the water in the branch pipe 3 will also enter the cleaning pipe 2 301. In this state, the water in the cleaning pipe 1 201 and the cleaning pipe 2 301 will all be sprayed out through the nozzle 5 to clean the spinneret placed on the spray rack 1; at the same time, the motor 2 601 works to drive the main The gear 602 rotates, and the meshing transmission slave gear 702 rotates. The slave gear 702 rotates, and the shaft 7 rotates. The rotation of the shaft 7 drives the eccentric wheel 701 to rotate. The eccentric wheel 701 rotates with the shaft 7011. Because the shaft 7011 is not at the center of the eccentric wheel 701, the ear plate 203 and the nozzle 2 fixed on the ear plate 203 rotate eccentrically, so that the cleaning pipe 1 201 and the cleaning pipe 2 301 can be used to clean the spinneret more conveniently, so that all surfaces of the spinneret are completely covered, the cleaning surface is increased, and a comprehensive cleaning operation is achieved;

[0041] For the rectangular spinneret, it is also placed on the spray rack 1, and the cleaning operation is the same as above, but the motor 1 403 in the linear guide 4 will work to drive the screw 402 to rotate. After the screw 402 rotates, because the lower part of the slider 404 is located in the inner cavity of the track 401 and is limited, it can only move linearly, thereby driving all the components installed above it to move linearly. At this time, the cleaning pipe 1 201 and the cleaning pipe 2 301 will also move accordingly, so as to comprehensively clean the surface of the rectangular spinneret and cover a wide area.

[0042] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
