Description

Technical Field

[0001] The present invention relates to the technical field of spinneret detection, and particularly to a detection device for high-strength and high-modulus polyethylene fiber spinnerets. Background Technique

[0002] In the production process of polyethylene fibers, the spinneret is one of the important components. The spinneret is usually made of metal and has many tiny holes on its surface. These holes are used to guide the polyethylene solution to flow out and form fibers.

[0003] In order to ensure the production quality of fibers, it is usually necessary to detect the spinneret. During the production process of the existing spinneret, if it is subjected to external force impacts or scratches, such as improper use of tools during installation or collision with other components, it may cause local deformation on the surface of the spinneret, resulting in defects such as depressions and protrusions. If the spinneret with depressions and protrusions is directly put into use without detection, the extrusion flow state of the spinning solution will be changed at the depression and protrusion parts, resulting in uneven thickness of the extruded fibers, problems such as hairiness and broken filaments, affecting the quality indexes such as the strength and uniformity of the fibers, and reducing the quality and performance of the product. Therefore, in order to ensure the production effect of fibers, a laser interferometer is usually used to detect the surface of the spinneret. However, the existing laser interferometer lacks obvious marking equipment. After detecting a depression on the surface of the spinneret, the subsequent operators still need to refer to complex detection data or images to find the problem points, which is rather troublesome and affects the detection efficiency. At the same time, the existing detection device lacks a cleaning device for the spinneret holes. After the detection device detects that the spinneret holes are blocked, the spinneret needs to be taken out later and the spinneret holes are manually dredged and cleaned, increasing the labor cost. Summary of the Invention

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figure 1 - Figure 16, a detection device for a high-strength and high-modulus polyethylene fiber spinneret, including a device main body 1. An installation cavity 9 is opened inside the device main body 1. A plurality of support plates 10 are fixedly connected inside the installation cavity 9. A spinneret 6 is installed inside the installation cavity 9. A plurality of spinneret holes 5 are opened on the spinneret 6. A bottom groove 7 is opened inside the device main body 1, and the bottom groove 7 penetrates into the installation cavity 9. An installation plate 2 is fixedly connected to the outer side wall of the device main body 1. A driving motor 3 is fixedly connected to the outer side wall of the installation plate 2. A reciprocating lead screw 4 is arranged at the output end of the driving motor 3. Slide rails are opened on both sides of the device main body 1. A marking box 8 is jointly slidably connected inside the slide rails on both sides. A driving member is fixedly connected to the top of the marking box 8, and the driving member is threadedly sleeved on the outer side wall of the reciprocating lead screw 4. A depression and protrusion detection mechanism is arranged on the marking box 8. The depression and protrusion detection mechanism includes a storage box 16 opened on the outer side wall of the marking box 8. An upper chamber 18 and a lower chamber 19 are opened inside the storage box 16. Liquid adding ports 17 that can be blocked are respectively opened inside the upper chamber 18 and the lower chamber 19, and the liquid adding ports 17 penetrate to the outside of the storage box 16. A plurality of sliding tubes 30 are jointly penetrated and slidably connected inside the upper chamber 18 and the lower chamber 19. Two upper dripping holes 20 and two lower dripping holes 21 are respectively opened on the plurality of sliding tubes 30. A plurality of electric rods 23 are fixedly connected inside the marking box 8, and the ends of the plurality of electric rods 23 are respectively fixedly connected to the corresponding sliding tubes 30. A plurality of laser interferometers 22 are fixedly connected to the bottom of the marking box 8.

[0020] Sliding ways 24 are fixedly connected to both sides of the marking box 8. The ends of the two sliding ways 24 are jointly connected to a detection box 15. Reciprocating threaded rods 25 are rotatably connected inside the two sliding ways 24. The ends of the reciprocating threaded rods 25 rotatably penetrate into the detection box 15. A wind wheel 27 is fixedly connected to one end of the reciprocating threaded rod 25 located inside the detection box 15. A driving plate 26 is threadedly sleeved on the outer side wall of the reciprocating threaded rod 25. A row brush 29 and an electrostatic dust suction plate 28 are fixedly connected to the outer side wall of the driving plate 26.

[0021] An air box 13 is communicated with the detection box 15. A plurality of fans 14 are arranged on the air box 13. A blowing detection and cleaning mechanism is arranged inside the detection box 15.

[0022] In this embodiment, when in use, first, the operator can place the spinneret 6 to be detected into the installation cavity 9 (refer to Figure 1 ). After the spinneret 6 is placed, at this time, the operator can turn on the driving motor 3 to drive the reciprocating lead screw 4 to rotate. When the reciprocating lead screw 4 rotates, it will drive the marking box 8 to move. When the marking box 8 moves from left to right (refer to Figure 2), the operator can turn on multiple fans 14 to blow air into the detection box 15. When the detection box 15 comes above the spinneret 6, during the movement of the detection box 15 along with the marking box 8, it blows air onto rows of spinneret holes 5 one by one. Since the wind speed monitor 11 is connected to the detection box 15 through multiple support arms 12, when the detection box 15 moves, the wind speed monitor 11 will move synchronously with the detection box 15 in the bottom groove 7. The wind speed monitor 11 moving in the bottom groove 7 will be located below the spinneret 6 (refer to Figure 3 ), and since the power of the multiple fans 14 is constant, the air volume blown by the fans 14 is also constant. When the detection box 15 blows air onto rows of spinneret holes 5 through the air outlet 31, the wind speed monitor 11 located below the spinneret 6 will monitor the blown air volume. If a blockage occurs in a row of spinneret holes 5 during the blowing detection, when the air blown by the detection box 15 passes through the spinneret holes 5, the air volume will attenuate. After the wind speed monitor 11 detects the attenuation of the air volume, when the dredging head 42 moves to the blocked row of spinneret holes 5, at this time the wind speed monitor 11 will make the telescopic rod 37 contract through the built-in signal transmitter. When the telescopic rod 37 contracts, it will first drive multiple dredging heads 42 to insert into the corresponding spinneret holes 5 to dredge a row of spinneret holes 5.

[0023] After the dredging head 42 is completely inserted into the spinneret hole 5, since the mounting plate 41 is larger than the aperture of the spinneret hole 5, after the dredging head 42 is completely inserted into the spinneret hole 5, the mounting plate 41 will abut against the surface of the spinneret hole 5 (refer to Figure 15 ), and at this time, as the telescopic rod 37 continues to contract, the pressing plate 38 will drive the pressing ring 48 to slide on the surface of the rotating thread 47, thereby driving the dredging head 42 to rotate in the spinneret hole 5 through the rotating rod 40 (refer to Figure 16), when the dredging head 42 rotates in the spinneret hole 5, the scraper 44 will scrape and clean the inner wall of the spinneret hole 5. When the rotating rod 40 drives the dredging head 42 to rotate, it will also drive the vent 49 to rotate synchronously. When the vent 49 rotates, under the action of centrifugal force, the slide plate 50 will overcome the pulling force of the tension spring 51 and open to both sides, and no longer block the rotating rod 40. When the pressure plate 38 pushes the dredging head 42 to move down and insert into the spinneret hole 5 to dredge the spinneret hole 5, it will also drive the positive side of the side magnet 36 that triggers the magnetic plate 39 to move. At this time, under the action of the repelling magnetic force of the two, the baffle plate 33 will overcome the elastic force of the pressing spring 35 and move forward Move away from the telescopic rod 37 to allow the flow hole 34 to move out of the air outlet 31, and the air outlet 31 is blocked by the unopened part of the baffle 33. When the air outlet 31 is blocked and no air is blown downward, and the vent 49 is opened during the rotation of the rotating rod 40, the wind blown into the detection box 15 by multiple fans 14 will enter the inside of the rotating rod 40 through the opened vent 49, and then be sprayed into the spinneret hole 5 through multiple air jet holes 43 to blow and clean the spinneret hole 5. Referring to the above principle, the detection box 15 can detect and clear the rows of spinneret holes 5 from left to right, and the labor cost is reduced by automatically detecting and clearing the spinneret holes 5.

[0024] Example 2: Please refer to Figure 1 - Figure 16 The air jet detection and cleaning mechanism includes an air jet port 31 connected to the detection box 15, a baffle plate 33 is slidably connected to the inside of the air jet port 31, a flow hole 34 is opened on the baffle plate 33, a pressing spring 35 is fixedly connected to the outer wall of the baffle plate 33, the other end of the pressing spring 35 is fixedly connected to the outer wall of the air jet port 31, a side magnet 36 is provided at the end of the baffle plate 33, and a lip plate 32 is provided at the bottom of the air jet port 31.

[0025] Telescopic rods 37 are provided on both sides of the lip plate 32, and the ends of the two telescopic rods 37 are commonly connected to a pressure plate 38, and a trigger magnetic plate 39 is provided on the pressure plate 38. The magnetic poles of the trigger magnetic plate 39 are the same as the magnetic poles of the side magnet 36, and a plurality of rotating rods 40 are provided on the pressure plate 38. The ends of the plurality of rotating rods 40 are all rotated to penetrate into the interior of the detection box 15, and the plurality of rotating rods 40 are all hollow. The ends of the rotating rods 40 are fixedly connected to a vent 49, and both sides of the vent 49 are slidably connected to a slide plate 50, and a tension spring 51 is fixedly connected to the outer wall of the slide plate 50, and the other end of the tension spring 51 is fixedly connected to the outer wall of the vent 49.

[0026] One end of the rotating rod 40 away from the ventilation port 49 is fixedly connected with a dredging head 42. The dredging head 42 is hollow. A plurality of air spray holes 43 are formed in the dredging head 42. Scrapers 44 are fixedly connected to both sides of the dredging head 42. An installation disc 41 is rotatably sleeved on the outer side wall of the dredging head 42. Limit rods 45 are fixedly connected to both sides of the installation disc 41. A return spring 46 is sleeved on the limit rod 45. The limit rod 45 is slidably connected with the pressing plate 38.

[0027] A rotating thread 47 is arranged on the outer side wall of the rotating rod 40. A pressing ring 48 is fixedly connected to the outer side wall of the pressing plate 38. The pressing ring 48 is threadedly sleeved on the rotating thread 47.

[0028] Support arms 12 are fixedly connected to both sides of the detection box 15. An anemometer 11 is connected to the two support arms 12 together.

[0029] An installation cavity 9 is formed inside the device main body 1. A plurality of support plates 10 are fixedly connected inside the installation cavity 9. A spinneret plate 6 is installed inside the installation cavity 9. A plurality of spinneret holes 5 are formed in the spinneret plate 6. A bottom groove 7 is formed inside the device main body 1. The bottom groove 7 penetrates into the installation cavity 9.

[0030] In this embodiment, when the detection box 15 detects rows of spinneret holes 5 from left to right, the fan 14 above the wind wheel 27 also blows air to drive the wind wheel 27 to rotate. When the wind wheel 27 rotates, it drives the reciprocating threaded rod 25 to rotate synchronously. When the reciprocating threaded rod 25 rotates, it drives the driving plate 26 to move reciprocally. The surface of the spinneret plate 6 is scraped and cleaned by the row brush 29 at the bottom. After the row brush 29 scrapes and cleans the dust on the surface of the spinneret plate 6, the electrostatic dust suction plate 28 adsorbs the cleaned dust, preventing dust from remaining on the surface of the spinneret plate 6 and affecting the flaw detection accuracy of the subsequent laser interferometer 22.

[0031] After the detection box 15 finishes detecting rows of spinneret holes 5 from left to right, multiple laser interferometers 22 at the bottom of the marking box 8 will immediately detect the surface of the spinneret plate 6. When a laser interferometer 22 detects a small protrusion on the surface of the spinneret plate 6, the laser interferometer 22 that detects the protrusion will drive the corresponding electric rod 23 to extend (this is prior art and will not be elaborated further). When the electric rod 23 extends, it will push the sliding tube 30 upward, causing one of the two lower dripping holes 21 to enter the lower chamber 19. After the lower dripping hole 21 enters the lower chamber 19, the green fluorescent agent stored in the lower chamber 19 will enter the sliding tube 30 through the lower dripping hole 21, and then drip onto the protrusion through the opening of the sliding tube 30 for marking to facilitate the operator's awareness. If the protrusion on the surface of the spinneret plate 6 is large, the extension amplitude of the electric rod 23 will increase at this time. When the electric rod 23 extends significantly, both of the two lower dripping holes 21 will enter the lower chamber 19. At this time, the green fluorescent agent in the lower chamber 19 will enter the sliding tube 30 through the two lower dripping holes 21. At this time, the amount of fluorescent agent transported by the sliding tube 30 is significantly increased compared to before. Correspondingly, the amount of fluorescent agent dripped by the sliding tube 30 onto the large protrusion is also significantly increased compared to before.

[0032] When a laser interferometer 22 detects a small depression on the surface of the installation cavity 9, the laser interferometer 22 that detects the depression will drive the corresponding electric rod 23 to shorten. When the electric rod 23 shortens, it will pull the sliding tube 30 downward, causing one of the two upper dripping holes 20 to enter the upper chamber 18. After the upper dripping hole 20 enters the upper chamber 18, the red fluorescent agent stored in the upper chamber 18 will enter the sliding tube 30 through the upper dripping hole 20, and then drip onto the depression through the sliding tube 30 for marking to facilitate the operator's awareness. If the depression on the surface of the spinneret plate 6 is large, the shortening amplitude of the electric rod 23 will increase at this time. When the electric rod 23 shortens significantly, both of the two upper dripping holes 20 will enter the upper chamber 18. At this time, the red fluorescent agent in the upper chamber 18 will enter the sliding tube 30 through the two upper dripping holes 20. At this time, the amount of fluorescent agent transported by the sliding tube 30 is significantly increased compared to before. Correspondingly, the amount of red fluorescent agent dripped by the sliding tube 30 onto the large depression is also significantly increased compared to before. By marking the depressions and protrusions, the operator can distinguish the depressions and protrusions on the surface of the spinneret plate 6 according to the colors of the marks, and distinguish the degrees of depression or protrusion by the sizes of the marks, which is convenient for subsequent maintenance.

[0033] It should be noted that the extension and shortening amplitudes of the electric rod 23, the extension and shortening timing, and after extending or shortening for a period of time, it will return to the initial state, all of which are controlled by a preset PLC program system (this is prior art and will not be elaborated further).

[0034] It should be noted that the fluorescent agents in this solution are all water-based fluorescent agents, which are easy to clean and dry quickly.

[0035] It should be noted that one-way valves are provided inside both the lower dripping holes 21 and the upper dripping holes 20, which can only transport the fluorescent agent into the sliding tube 30 and will not leak outwards.

[0036] It should be noted that after one side of the installation cavity 9 has been inspected for flaws, the back side of the installation cavity 9 can be inspected again with reference to the above principle.

[0037] It should be noted that when the wind speed monitor 11 detects that the spinneret holes 5 are blocked, and then when the dredging head 42 moves to the row of blocked spinneret holes 5, at this time the wind speed monitor 11 will cause the telescopic rod 37 to contract through the built-in signal transmitter. The whole process is also controlled by a preset PLC program (this is prior art and will not be elaborated too much).

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
