Description

Technical Field

[0001] The invention belongs to the technical field of spinning, in particular to a nylon spinneret cleaning device. Background Art

[0002] Nylon is a polymer material with good wear resistance. During the spinning process, the friction between the nylon spinneret and the fiber material is not easy to cause wear, which makes it have a long service life. At the same time, the nylon spinneret also has a certain corrosion resistance. For some chemically corrosive spinning solutions, the nylon spinneret can resist its erosion, ensuring the quality of the spinning and the performance of the spinneret.

[0003] In the prior art, a high-pressure spray cleaning method is often used to clean the spinneret. The cleaning liquid is pressurized by a high-pressure pump, and then the cleaning liquid is sprayed onto the nylon spinneret in the form of a high-speed spray through a specially designed nozzle. In the above process, the design of the nozzle is particularly important for the cleaning effect. Although the spinneret can be cleaned well by high-pressure spray, when the spinneret holes on the spinneret are blocked, the reaction force after the water flow contacts the spinneret will cause the water flow to change direction, dispersing the impact force of the water flow, thereby affecting the treatment effect on the spinneret holes. Therefore, improvements are made to address the above problems. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 8As shown, the present invention provides a nylon spinneret cleaning device, including a supporting mechanism 1, the supporting mechanism 1 is composed of a supporting frame 101 placed on the ground, a driving motor 102 arranged on the side of the supporting frame 101 and a hydraulic cylinder 103 arranged on the top of the supporting frame 101, and also includes a positioning mechanism 2, the positioning mechanism 2 is arranged in the middle of the supporting frame 101 and is used to place the nylon spinneret; a boosting mechanism 3, the boosting mechanism 3 is arranged on both sides of the positioning mechanism 2; a diversion mechanism 4, the diversion mechanism 4 is arranged inside the boosting mechanism 3; a collecting mechanism 6, the collecting mechanism 6 is arranged outside the boosting mechanism 3 and is used to collect impurities washed down; a covering mechanism 7, the covering mechanism 7 is arranged inside the boosting mechanism 3 and is located between the positioning mechanism 2 and the boosting mechanism 3; an extrusion mechanism 8, the extrusion mechanism 8 is arranged inside the boosting mechanism 3; a transmission mechanism 5, the transmission mechanism 5 is arranged inside the boosting mechanism 3 and is used to intermittently limit the covering mechanism 7 through the extrusion mechanism 8; wherein, the boosting mechanism 3 includes a fixed ring 301, a movable cover 302 and a connecting water pipe 303, the fixed ring 301 is fixedly connected to the positioning mechanism 2, the movable cover 302 is movably sleeved on one end of the fixed ring 301, and the connecting water pipe 303 is fixedly installed on the fixed ring 301, the diversion mechanism 4 includes a water pass plate 401, a guide column 402 and a sealing cover 403, the water pass plate 401 is fixedly connected to the fixed ring 301, the guide column 402 is fixedly installed on one end of the water pass plate 401 away from the positioning mechanism 2, the sealing cover 403 is movably sleeved on the guide column 402, the surface of the water pass plate 401 is provided with holes for aligning the surface of the spinneret, and the covering mechanism 7 includes a connecting block 701 annularly arranged on the inner wall of the fixed ring 301 and a covering plate 702 rotatably connected between adjacent connecting blocks 701.

[0036] The above scheme is adopted: by injecting cleaning liquid into the interior of the fixed ring 301 and pressing down the movable cover 302 through the hydraulic cylinder 103, the air can be compressed by pressure, and the impurities in the spinneret holes on the spinneret are first flushed out by the air, and then the pressure flushes the cleaning liquid to the spinneret through the holes on the water pass plate 401, so as to achieve a better cleaning effect; and under the action of gravity, the covering plate 702 located inside the lower fixed ring 301 covers the surface of the water pass plate 401, and the sealing cover 403 moves downward under the action of gravity and no longer closes the water pass plate 401, so that the flushed impurities directly reach between the water pass plate 401 and the movable cover 302 located below, so that when the driving motor 102 drives the positioning mechanism 2 to rotate one hundred and eighty degrees and flush again, no impurities will be introduced. In this way, the cleaning liquid can be recycled, and the cleaning liquid is effectively saved.

[0037] like Figure 6As shown, the positioning mechanism 2 includes a positioning platform 201, a supporting plate 202 and a fixed plate 203. The positioning platform 201 is rotatably connected to the support frame 101, the output shaft of the driving motor 102 is fixedly connected to the positioning platform 201, the piston of the supporting plate 202 is connected to the inside of the positioning platform 201, the fixed plate 203 is fixed to the surface of the supporting plate 202 by bolts, and the spinneret is located between the supporting plate 202 and the fixed plate 203.

[0038] The above solution is adopted: in this way, the spinneret can be quickly replaced, thereby increasing the practicality of the device.

[0039] like Figure 2 and Figure 3 As shown, the water-passing plate 401 is in the shape of a truncated cone. All the covering plates 702 located inside one of the fixing rings 301 are assembled to form a truncated cone and can cover the holes on one side of the water-passing plate 401. The covering plate 702 located above the positioning platform 201 hangs naturally and its bottom is inclined toward the axis of the fixing ring 301.

[0040] With the above solution, the water plate 401 can cover the holes on the surface of the water plate 401 when it is below the positioning platform 201, and can naturally hang down by gravity when it is above the positioning platform 201, which will not affect the water flow flushing the spinneret when pressure is applied from above.

[0041] like Figure 4 and Figure 5 As shown, the transmission mechanism 5 includes a rotating shaft 501, a gear 502, a tooth plate 503, a drain plate 504, an internal meshing ratchet mechanism 505 and an extrusion plate 506. The rotating shaft 501 is rotatably connected to the rotating shaft 501. The gear 502 and the internal meshing ratchet mechanism 505 are respectively fixed at both ends of the rotating shaft 501. The tooth plate 503 is fixedly installed at the bottom of the movable cover 302 and meshes with the gear 502. The drain plate 504 is annularly fixed to the middle part of the rotating shaft 501. The gear 502, the tooth plate 503 and the internal meshing ratchet mechanism 505 are all located in the inner wall of the fixed ring 301. The internal meshing ratchet mechanism 505 is composed of a ratchet and a rotating wheel equipped with a pawl. The rotating shaft 501 is fixedly connected to the ratchet, and an extrusion plate 506 is fixedly installed on the outer side of the rotating wheel.

[0042] The above scheme is adopted: the drain plate 504 can drive the rotating shaft 501 to rotate through the gear 502 when the tooth plate 503 moves, so that the water flow is input to the inside of the collecting mechanism 6 through the rotation of the drain plate 504, so as to collect the impurities; through the cooperation of the internal meshing ratchet mechanism 505 and the squeezing plate 506, the covering plate 702 can be locked by squeezing the squeezing mechanism 8 when the movable cover 302 located above the positioning platform 201 moves down for the third time. On this basis, after the positioning platform 201 rotates one hundred and eighty degrees, the locked covering plate 702 will not cover the water flow plate 401, and the air flow and water flow can backwash the holes on the water flow plate 401 located below at this time to prevent clogging by impurities. It is worth noting that the rotating wheel in the internal meshing ratchet mechanism 505 is fixed by the friction between it and the fixing ring 301.

[0043] like Figure 7 As shown, the collecting mechanism 6 includes a collecting bin 601 and a filter plate 602. The collecting bin 601 is installed on the outer side of the fixing ring 301. The inner wall of the fixing ring 301 is also provided with a through groove 311 connecting the collecting bin 601 and the inner cavity of the fixing ring 301 and a slide groove 312 for the filter plate 602 to slide up and down. The top of the filter plate 602 located inside the upper fixing ring 301 is coplanar with the bottom of the through groove 311, and the filter plate 602 located inside the lower fixing ring 301 blocks the through groove 311.

[0044] The above scheme is adopted: the set collection bin 601 can collect impurities, the set filter plate 602 can not filter the water flow when it is located above the positioning platform 201, and the impurities in the water flow directly enter the collection bin 601 through the through groove 311, and the filter plate 602 located below the positioning platform 201 can fall freely in the through groove 311 under the action of gravity. At this time, the impurities inside the collection bin 601 are blocked by the filter plate 602 and will not flow back into the cleaning liquid, thereby ensuring the cleanliness of the cleaning liquid.

[0045] like Figure 5 and Figure 8As shown, the extrusion mechanism 8 includes a pressing assembly 801 and a pressure assembly 802. The pressing assembly 801 includes a connecting ring 8011 and a connecting plate 8012. The connecting plate 8012 is annularly installed on the surface of the connecting ring 8011. The pressure assembly 802 includes a spring guide rod 8021 and a spring telescopic block 8022. The spring telescopic block 8022 is fixedly connected to the connecting ring 8011. The spring guide rod 8021 is fixedly installed on the top of the connecting block 701. The spring telescopic block 8022 is sleeved on the spring guide rod 8021. On the surface of the spring guide rod 8021, the spring expansion block 8022 has a tendency to move upward, and the lower end of the spring expansion block 8022 is located inside the connecting block 701. The rotating shaft of the covering plate 702 extends into the inner cavity of the connecting block 701. When the tooth plate 503 moves down to the maximum value, the internal meshing ratchet mechanism 505 is driven by the gear 502 and the rotating shaft 501 to rotate one hundred and twenty degrees. The center angle of the extrusion plate 506 is one hundred and twenty degrees, and the extrusion plate 506 can squeeze the connecting plate 8012 to move downward.

[0046] The above scheme is adopted: the spring expansion block 8022 inside the same fixed ring 301 is connected by the provided connecting ring 8011, the provided connecting plate 8012 can be intermittently in pressure contact with the extrusion plate 506, and the spring expansion block 8022 itself can be expanded and contracted. When the connecting plate 8012 is squeezed and moved downward by the extrusion plate 506, the spring expansion block 8022 can be moved downward to squeeze the rotation axis of the covering plate 702, thereby locking the covering plate 702. At the same time, the expansion and contraction characteristics of the spring expansion block 8022 can ensure that there is a certain amount of buffer when squeezing the rotation axis of the covering plate 702, and the provided spring guide rod 8021 can restore the spring expansion block 8022 and the pressing component 801 to their original positions through elastic force.

[0047] The working principle and use process of the present invention:

[0048] When using, first place the device as Figure 1 At this time, the cover plate 702 at the bottom naturally falls to cover the surface of the water-passing plate 401 below, and the sealing cover 403 at the bottom no longer blocks the middle of the water-passing plate 401, and the filter plate 602 at the bottom slides into the through groove 311;

[0049] Take out the supporting plate 202, and place the spinneret between the supporting plate 202 and the fixed plate 203, then install the supporting plate 202 into the positioning platform 201, and inject cleaning liquid into the fixed ring 301 through the connecting water pipe 303 located above the positioning platform 201. After injection, close the connecting water pipe 303, start the hydraulic cylinder 103 to press down the movable cover 302 located above the positioning platform 201, and when the movable cover 302 located above moves down, it can squeeze the air and water inside, and the air will rush through the spinneret holes to open the blocked area, and the water will flush the spinneret. After flushing, the cleaning liquid will flow along the surface of the cover plate 702 below after passing through the spinneret and finally be located between the water-passing plate 401 below and the movable cover 302;

[0050] Synchronously, the toothed plate 503 fixed on the movable cover 302 moves downward to drive the rotating shaft 501 to rotate through the gear 502, and the drainage plate 504 located on the rotating shaft 501 rotates, thereby stirring the cleaning liquid, so that the cleaning liquid is discharged into the collecting bin 601. When the cleaning liquid contains impurities, the impurities can be discharged into the collecting bin 601. At the same time, the internal meshing ratchet mechanism 505 rotates to drive the squeezing plate 506 to rotate along the axis of the rotating shaft 501.

[0051] After the cleaning liquid inside the upper fixed ring 301 quickly rinses the spinneret under pressure, the driving motor 102 is started to drive the positioning platform 201 to rotate 180 degrees, and the movable cover 302 located at the top is pressed down again by the hydraulic cylinder 103. When repeated for the third time, the extrusion plate 506 is in pressure contact with the connecting plate 8012 and drives the connecting ring 8011 and the spring telescopic block 8022 to move downward, and the spring telescopic block 8022 is in pressure contact with the rotating shaft of the covering plate 702 to lock the covering plate 702. After the locking, the positioning platform 201 is rotated 180 degrees again, and the covering plate 702 located below will not freely fall on the surface of the water passing plate 401 below. At this time, the airflow and water flow can backwash the water passing plate 401 below.

[0052] After cleaning is completed, the cleaning liquid can be discharged by opening the connecting water pipe 303 located at the bottom, and the spinneret can also be replaced for cleaning, but the cleaning liquid needs to be replaced after long-term use.
