Detailed implementation manners

[0019] Embodiment 1: Refer to Figures 1-9 , an intelligent processing and polishing equipment for wool-type fiber spinnerets, including a polishing box 1 and a box cover 2. A hydraulic telescopic rod 3 is connected between the box cover 2 and the polishing box 1 to realize the opening and closing operation between the box cover 2 and the polishing box 1 through the hydraulic telescopic rod 3. A spinneret 4 is placed in the polishing box 1. The top end of the box cover 2 is communicated with a liquid injection port 201, and the bottom of the polishing box 1 is communicated with a liquid discharge port 101. Clamping plates 5 are arranged around the spinneret 4. There are four clamping plates 5, and the four clamping plates 5 are arranged in a circular array in the circumferential direction of the spinneret 4. The bottom end of the clamping plate 5 is connected with a moving mechanism 6. The moving mechanism 6 drives the clamping plate 5 to move horizontally in the radial direction of the spinneret 4, so as to fix the spinneret 4 through the four movable clamping plates 5, and the spinneret 4 can be moved while maintaining the clamping through the coordinated movement of the four clamping plates 5. For example, taking Figure 3 as an example, it is divided into four clamping plates 5, namely the upper clamping plate moves upward, the left clamping plate moves leftward, the lower clamping plate moves upward, the right clamping plate moves leftward, and moves an appropriate distance according to the radius of the spinneret 4, and the spinneret 4 can be displaced towards the upper left corner direction; It also includes four groups of liquid pressure monitoring modules located below the spinneret 4. The four groups of liquid pressure monitoring modules correspond to the position of the moving mechanism 6. The liquid pressure monitoring module is used to monitor the impact pressure of the fluid below the spinneret 4 in real time; Four groups of rebound state monitoring modules are located above the periphery of the spinneret 4, and the four groups of rebound state monitoring modules are arranged at intervals from the liquid pressure monitoring modules, that is, the rebound state monitoring modules are arranged between two adjacent liquid pressure monitoring modules, and the rebound state monitoring modules are used to monitor in real time the impact force of the fluid and the abrasive rebounding upward after impacting the spinneret 4; The monitoring data of the rebound state monitoring module and the liquid pressure monitoring module are uploaded to the central processing unit. After comprehensive analysis, it is determined whether the corresponding position of the spinneret 4 is blocked. If the rebound impact force monitoring data of one of the rebound state monitoring modules is too large, and the monitoring data of the corresponding liquid pressure monitoring modules on both sides are too small, it means that the holes at the corresponding position of the spinneret 4 are blocked, causing a large amount of abrasive to rebound upward and the fluid cannot effectively pass downward. Therefore, the position of the spinneret 4 is adjusted by controlling the moving mechanism 6 and the clamping plate 5, so that the spinneret 4 moves from the blockage monitoring position toward the center of the spinneret 4. Under the action of inertia, the blocked abrasive moves in the opposite direction of the moving direction of the spinneret 4, that is, the blocked abrasive moves toward the periphery of the spinneret 4 to achieve clearing, and continuous monitoring is performed to analyze and feedback the adjusted data. During the polishing operation of the spinneret 4 by the fluid and the abrasive, intelligent adjustments are made according to the real-time polishing state to improve the effectiveness of the polishing operation and improve the operation efficiency.

[0020] In the present invention, the moving mechanism 6 is provided with a guide frame 7 fixed to the inner wall of the polishing box 1, and the guide frame 7 is extended in the horizontal direction along the radial direction of the spinneret 4. A driving screw 8 is rotatably connected between the two ends of the guide frame 7, and one end of the driving screw 8 is transmission-connected to a motor 10. It should be noted that one end of the driving screw 8 extends to the outside of the polishing box 1, that is, a sealing shaft hole is opened at a position corresponding to the polishing box 1 shell and the driving screw 8, and the outer wall of the driving screw 8 is rotatably connected to the sealing shaft hole, and the shell of the motor 10 is installed on the polishing box 1. The outer wall position is fixed between the output shaft of the motor 10 and the driving screw 8; the outer wall of the driving screw 8 is threadedly connected with a moving block 9, and the moving block 9 and the guide frame 7 are limited and slided, and the clamping plate 5 is installed above the moving block 9. The cross-sections of the guide frame 7 and the moving block 9 are set to a rectangular structure. The outer walls on both sides of the moving block 9 are in sliding contact with the inner wall bracket of the guide frame 7, so that the moving block 9 is limited by the guide frame 7 so that the moving block 9 will not rotate with the rotation of the driving screw 8, so as to realize the moving operation of the moving block 9 with the clamping plate 5 along the guide frame 7.

[0021] In the present invention, the clamping plate 5 is arranged in an L-shaped structure. Vertically downward extending positioning screws 11 are fixed on both sides of the bottom of the clamping plate 5 and located on both sides of the driving screw 8. Through holes are formed at the positions corresponding to the positioning screws 11 on the top of the moving block 9. The positioning screws 11 are in sliding contact with the through holes. Nuts 12 are threadedly connected to the positions of the positioning screws 11 at both ends of the through holes. Thus, the clamping plate 5 is installed on the moving block 9 through the positioning screws 11 and the nuts 12, so that the clamping plate 5 moves and is positioned along with the moving block 9. And through the arrangement of the positioning screws 11 and the nuts 12, the clamping plate 5 is separated from the moving block 9 and the guide frame 7. The height of the spinneret plate 4 can be vertically adjusted by the clamping plate 5 while separating the bottom of the spinneret plate 4 from the guide frame 7, so that the fluid and abrasive passing through the spinneret plate 4 are sent downward to avoid congestion at the bottom of the spinneret plate 4, thereby avoiding affecting the polishing operation effect of the fluid and abrasive on the surface of the spinneret plate 4.

[0022] In the present invention, the liquid pressure monitoring module is provided with a first pressure sensor 14 corresponding to the position of the moving mechanism. An installation frame 13 is fixed at the position corresponding to the first pressure sensor 14 on the side of the guide frame 7. The first pressure sensor 14 is installed on the installation frame 13. The first pressure sensor 14 is located below the spinneret plate 4, and the detection head of the first pressure sensor 14 is vertically upward. Thus, the impact force of the fluid or abrasive passing through the spinneret plate 4 at a local position is monitored by the first pressure sensor 14 at a fixed position. When the data real-time monitored by the first pressure sensor is too small, it indicates that there may be abrasive blockage above the corresponding local position of the spinneret plate 4, resulting in the fluid or abrasive being unable to effectively penetrate and fall. Therefore, it may be necessary to displace the spinneret plate 4 from the position of the first pressure sensor 14 towards the center of the spinneret plate 4.

[0023] In the present invention, a dispersion mesh bag 15 is arranged at the position corresponding to the liquid injection port 201 on the inner wall of the top of the box cover 2. The top of the dispersion mesh bag 15 is open. An annular frame 16 is installed at the position corresponding to the dispersion mesh bag 15 on the inner wall of the top of the box cover 2. A horizontal ring 151 is fixed at the top of the outer wall of the dispersion mesh bag 15. The outer wall of the horizontal ring 151 is slidably connected to the inner wall of the annular frame 16. A vertical ring 152 is fixed at the top end of the dispersion mesh bag 15. Tooth grooves are formed in an annular array on the inner wall of the vertical ring 152. A second motor 17 is installed on the top of the box cover 2. A gear 18 meshing with the tooth grooves is fixed on the output shaft of the second motor 17. Thus, the fluid and abrasive entering through the liquid injection port 201 are dispersed by rotating the dispersion mesh bag 15 and then contact the spinneret plate 4 for polishing operation.

[0024] In the present invention, a dispersion mechanism 19 is provided at the position between two adjacent moving mechanisms 6 in the lid 2 of the box, that is, a total of four sets of dispersion mechanisms 19 are provided. The dispersion mechanism 19 is provided with a vertical spindle 20. Both sides of the spindle 20 are provided with blade plates 22. A sleeve 23 is fixed to the side of the blade plate 22 close to the spindle 20. The inner wall of the sleeve 23 is rotationally connected to the spindle 20 through a torsion spring. The rebound state monitoring module is set as a torsion monitor located in the sleeve 23. The torsion monitor is used to monitor the torsion of the corresponding torsion spring in real time. Under normal conditions, the two blade plates 22 are placed normally under the action of the torsion spring, and the torsion of the torsion spring is set to zero at this time. During the polishing operation, a small amount of fluid and abrasives in the dispersion mesh bag 15 centrifugally impact on the blade plates 22, and some of the abrasives impacting on the upper surface of the spinneret 4 rebound and impact on the blade plates 22. When the top surface of the spinneret 4 is blocked, a large amount of fluid and abrasives will rebound onto the blade plates 22, so that the blade plates 22 will be impacted by more abrasive rebounds in a short time. Moreover, due to the accumulation on the top surface of the spinneret 4, the distance of the abrasive rebounding onto the blade plates 22 is reduced and the rebound impact force is increased, which will increase the deflection angle of the blade plates 22 and the duration. If the deflection angle of the blade plates 22 exceeds a certain value and is maintained for a set time, it indicates that there is abrasive blockage on the surface of the corresponding position spinneret 4, which affects the normal polishing operation, so the movement of the spinneret 4 needs to be controlled; the blade plates 22 connected by the torsion spring cooperate with the rotating dispersion mesh bag to improve the uniformity of the polishing operation of the abrasive on the surface of the spinneret 4, and the area of the rebound state monitoring is expanded through the setting of the blade plates 22, so as to improve the accuracy and comprehensiveness of the judgment on whether there is abrasive blockage on the surface of the spinneret 4.

[0025] In the present invention, a fixing frame 21 is installed between the top and bottom of the spindle 20 and the inner wall of the lid 2. A limiting block 24 is installed at the position of the spindle 20 facing the spinneret 4. The limiting block 24 is used to prevent the blade plate 22 from rebounding too far during the rebound, which affects the polishing operation effect of the abrasive on the surface of the spinneret 4.

[0026] In the present invention, the control logic of the central processing unit is as follows: Step 1: The liquid pressure monitoring module collects the impact pressure of the fluid below the spinneret in real time, records the data at a fixed frequency, filters the collected data to remove noise interference, and uses the moving average filtering method to calculate the average value of the past n data points as the effective pressure value at the current moment: Let the collected pressure data sequence be , the size of the sliding window is n, and n ≤ m, then the effective pressure value P t The calculation formula is ; The rebound state monitoring module monitors the torsion force of the torsion spring in real time, also collects data at a fixed frequency, normalizes the torsion force data to make its value between 0 and 1 for subsequent analysis, compares the normalized data with the torsion force value in the normal state, and zeroes the torsion force value in the normal state to calculate the torsion force change amount: Let the collected torsion force data be , the normalized torsion force value , where T min and T max are the minimum and maximum torsion forces collected respectively, calculate the torsion force change amount at the current moment t, and record the duration t i of each non-zero torsion force change amount; Step 2: Comprehensive calculation, calculate the comprehensive blockage index C, , and are the weights of the pressure value and the torsion force change amount respectively, and , P max is the maximum value in the pressure data, which is used to normalize the pressure value; represents the sum of all t i , where t i represents the time value at different moments or different stages. Here, all relevant time values are accumulated to obtain the total time amount; represents the product of the torsion force change amount and the duration of the time period within the i-th time period, and is the sum of all these products to reflect the comprehensive impact of the torsion force change and its maintenance time on the entire system; Step 3: Set a comprehensive blockage threshold C th . When C > C th , it is considered that there is a blockage at the corresponding position of the spinneret. The value of C th can be determined by experience and historical records.

[0027] Example 2: Refer to Figures 2-6 and Figures 8-11, A polishing device for intelligent processing of wool-type fiber spinnerets. On the basis of Embodiment 1, an extension plate 25 is installed at the bottom of the moving block 9. The extension plate 25 extends horizontally towards the spinneret 4. A through groove one 251 is opened at the top of the extension plate 25. On one side of the moving block 9 close to the spinneret 4, there is a blade 26. Both ends of the blade 26 are fixed with rotating shafts. The outer wall of the rotating shaft is rotationally connected with an auxiliary frame 27 through a torsion spring. The bottom end of the auxiliary frame 27 is fixed to the top of the extension plate 25. A through groove two 261 corresponding to the driving screw 8 is opened on the side of the blade 26. The blade 26 is inclined upwards away from the moving block 9, and the end of the blade 26 away from the moving block 9 is upturned. When impacted by the fluid or abrasive passing through the spinneret 4, the end of the blade 26 away from the moving block 9 will be squeezed downwards, and the end of the blade 26 close to the moving block 9 will impact upwards on the side wall of the moving block 9 and squeeze the side wall of the moving block 9. Due to the differences in fluid movement and abrasive distribution, the blade 26 impacts the side of the moving block 9 at intervals, thereby generating mechanical vibrations at the position of the clamping plate 5 around the spinneret 4 to disperse the abrasive on the surface and prevent the abrasive from accumulating and blocking.

[0028] In the present invention, a contact piece 901 is provided on one side of the moving block 9 close to the blade 26. A through hole is opened at the position of the contact piece 901 and the driving screw 8. A pressure sensor two is provided between the contact piece 901 and the moving block 9. When the fluid and abrasive passing through the spinneret 4 impact the upturned end of the blade 26, the end of the blade 26 close to the moving block 9 impacts and squeezes at the position of the contact piece 901. If the extrusion force is too small, the amount of fluid and abrasive passing through the spinneret 4 above the surface is too small, that is, there is a blockage above the corresponding position of the spinneret 4. Therefore, it is necessary to control the position of the moving spinneret 4. The blade 26 is used to improve the monitoring area and accuracy of the liquid passing through below. The monitoring data of the pressure sensor two is uploaded to the central processing unit. The pressure sensor two collects the extrusion force data of the blade impacting the contact piece. Let the collected extrusion force data sequence be , and the sliding average filtering method is also used for processing. The size of the sliding window is set to k, k ≤ m, then the effective extrusion force value F at the current moment t t The calculation formula is ; Calculate the comprehensive blockage index C, , , and are the weights of the pressure value and the torque change amount respectively, and , F max is the maximum value in the extrusion force data.

[0029] As described above, it is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
