Description

Technical Field

[0001] This invention relates to the technical field of corona treatment for cashmere yarn, and in particular to a method and equipment for corona treatment of cashmere yarn. Background Technology

[0002] Cashmere yarn is a knitting yarn for knitting needles made from cashmere. During the processing of cashmere yarn, it needs to be corona treated by a corona machine to improve the surface properties of the cashmere yarn, giving it better wettability and dyeability.

[0003] Existing corona treatment machines, such as the one disclosed in utility model patent application number 201720927896.7 and the one disclosed in utility model patent application number 202223336819.4, can all perform corona treatment on cashmere yarn.

[0004] However, during use, it was found that the existing corona treatment machine has a relatively simple structure, which makes it inconvenient to treat the ozone generated during corona treatment and to further treat the hydrophilicity of cashmere yarn. Furthermore, it is inconvenient to automatically adjust the operating parameters of the equipment during the corona treatment of cashmere yarn, resulting in poor practicality. Therefore, there is an urgent need for a method and equipment for corona treatment of cashmere yarn to improve the above problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a method and equipment for corona treatment of cashmere yarn, which involves loading cashmere yarn onto a conveying mechanism for conveying, adjusting the tension of the cashmere yarn through a tensioning mechanism, drying the cashmere yarn, subjecting the cashmere yarn to corona treatment through a corona treatment mechanism, subjecting the cashmere yarn to oxidation treatment through an oxidation mechanism, cooling the cashmere yarn through a cooling mechanism, and finally detecting the treatment effect of the cashmere yarn through a detection mechanism. This improves the practicality of the equipment.

[0006] The present invention provides a method and apparatus for corona treatment of cashmere yarn, comprising a conveying mechanism; and further comprising a corona treatment mechanism, a tensioning mechanism, an oxidation mechanism, a cooling mechanism, and a detection mechanism, wherein the conveying mechanism, tensioning mechanism, oxidation mechanism, cooling mechanism, and detection mechanism are all mounted on the corona treatment mechanism;

[0007] The conveying mechanism conveys the cashmere yarn, the tensioning mechanism adjusts the tension of the cashmere yarn, the corona treatment mechanism performs corona treatment on the cashmere yarn, the oxidation mechanism performs oxidation treatment on the cashmere yarn, the cooling mechanism oxidizes the cashmere yarn, and the detection mechanism detects the cashmere yarn.

[0008] The cashmere yarn is loaded onto a conveyor mechanism for transport. Simultaneously, a tensioning mechanism adjusts the tension of the cashmere yarn and dries it. Next, a corona treatment mechanism applies corona treatment, followed by an oxidation treatment. Finally, a cooling mechanism cools the cashmere yarn, and a testing mechanism assesses the treatment effect, thereby improving the equipment's practicality.

[0009] Preferably, the corona treatment mechanism includes a worktable, a corona chamber, a corona treatment head, multiple sets of airbag rings, multiple sets of solenoid valves, and an exhaust pump. The worktable has an internal chamber. The corona chamber is mounted on the top of the worktable and is equipped with an exhaust valve, a feed inlet, and a discharge outlet. The corona treatment head is mounted on the corona chamber. The multiple sets of airbag rings are respectively mounted on the feed inlet and discharge outlet of the corona chamber. One end of each of the multiple sets of solenoid valves is mounted on one of the multiple sets of airbag rings. The exhaust pump is installed inside the worktable, and the other end of each of the multiple sets of solenoid valves supplies air. The pipeline is connected to the exhaust port of the exhaust pump; one end of the cashmere yarn is inserted into the inlet of the corona box and then extended out of the outlet of the corona box. Then, the exhaust pump and solenoid valve are turned on to exhaust air into the air bladder ring, causing the air bladder ring to expand and narrow the inlet and outlet of the corona box, reducing the leakage of air from the corona box. Then, a high-voltage electric field is released inside the corona box through the corona machine head to corona treat the cashmere yarn. At the same time, the high-voltage electric field converts the oxygen in the corona box into ozone, thereby improving the practicality of the equipment.

[0010] Preferably, the oxidation mechanism includes multiple sealing mechanisms, a frame, a circulating pump, an intake pipe, a circulation pipe, an oxygen generator, a delivery pipe, and an intake fan. The multiple sealing mechanisms are all mounted on the corona chamber. The frame is mounted on a workbench. The circulating pump is mounted on the frame. One end of the intake pipe passes through an air bladder ring and communicates with the interior of the corona chamber. The right end of the circulation pipe communicates with the interior of the multiple sealing mechanisms. The left end of the circulation pipe is connected to the intake port of the circulating pump. The exhaust port of the circulating pump communicates with the interior of the intake pipe. The oxygen generator is mounted on the frame, and its exhaust port communicates with the interior of the intake pipe via a delivery pipe. An intake fan is installed at the top of the intake pipe. Before corona treatment begins, oxygen is produced by an oxygen generator and discharged into the intake pipe. At the same time, air is discharged into the intake pipe by the intake fan, allowing the oxygen and air to mix and enter the corona chamber. This facilitates the generation of a large amount of ozone during the corona treatment process. Afterward, the oxygen generator and intake fan are turned off, and the circulation pump is turned on to draw the ozone from the corona chamber into multiple sealing mechanisms. These mechanisms cause the ozone to oxidize the cashmere yarn. The circulation pump then discharges the ozone from the multiple sealing mechanisms back into the corona chamber for reuse, thereby improving the equipment's practicality.

[0011] Preferably, the sealing mechanism includes a first transparent tube, a second transparent tube, a first light-shielding tube, a second light-shielding tube, a cylinder, and a first guide wheel. One end of the first transparent tube and the first light-shielding tube are both mounted on a corona box.

One end of the cylinder is mounted on the first light-shielding tube, and the other end is mounted on the second light-shielding tube. The first guide wheel is mounted on the right end of the second light-shielding tube. Cashmere yarn passes between the first and second transparent tubes, while ozone flows within them. The cashmere yarn is irradiated by the ultraviolet lamps in the first and second light-shielding tubes, allowing the ultraviolet light to work in conjunction with the ozone to treat the cashmere yarn. Simultaneously, the ultraviolet light disinfects and sterilizes the cashmere yarn. During the treatment process, the treatment time is adjusted by extending or retracting the cylinder, thereby improving the practicality of the equipment.

[0012] Preferably, the conveying mechanism includes a raw material shaft, a winding shaft, a first motor, a second motor, and multiple sets of second guide wheels. The raw material shaft and the winding shaft are both mounted on the left end of the worktable. The first motor and the second motor are both fixedly mounted on the worktable, providing power to the raw material shaft and the winding shaft respectively. Multiple sets of second guide wheels are respectively mounted on the left and right ends of the worktable. A through-passage is provided laterally at the bottom of the worktable. Cashmere yarn is wound onto the raw material shaft. Then, one end of the cashmere yarn is passed through a corona box, a first transparent tube, a second transparent tube, a cooling mechanism, and a detection mechanism. The other end of the cashmere yarn is then fixed to the winding shaft, supported by multiple sets of second guide wheels. Afterward, the first motor and the second motor are turned on, causing the raw material shaft to loosen the cashmere yarn and the winding shaft to wind it up, allowing the equipment to continuously process the cashmere yarn, thereby improving the equipment's practicality.

[0013] Preferably, the cooling mechanism includes a cooling chamber, a thermoelectric cooling plate, and a cooling fan. The cooling chamber is installed in the through-passage of the workbench, with a first inlet at the right end and a first outlet at the left end. The thermoelectric cooling plate is installed on the cooling chamber, with its cooling end located inside the chamber and its heat dissipation end located below. The cooling fan is installed on the heat dissipation end of the thermoelectric cooling plate. The processed cashmere yarn is passed through the cooling chamber, and the thermoelectric cooling plate cools the cashmere yarn inside the chamber. Simultaneously, the cooling fan dissipates heat from the thermoelectric cooling plate, thereby improving the practicality of the equipment.

[0014] Preferably, the testing mechanism includes a testing box, multiple sets of cameras, and multiple sets of supplementary lights. The testing box is installed in the through-passage of the workbench, with a second inlet at the right end and a second outlet at the left end. A data analysis module is installed inside the testing box, and the multiple sets of cameras and supplementary lights are all installed inside the testing box. The cooled cashmere yarn is passed through the testing box, and the multiple sets of cameras capture images of the cashmere yarn. At the same time, the multiple sets of supplementary lights provide supplementary lighting for the multiple sets of cameras. Then, the data analysis module inside the testing box analyzes the images captured by the multiple sets of testing boxes, and adjusts the operating parameters of the cashmere yarn corona treatment equipment based on the analysis results, thereby improving the practicality of the equipment.

[0015] Preferably, the tensioning mechanism includes multiple sets of hydraulic cylinders, a support frame, a third motor, a tensioning shaft, and multiple sets of heating elements. One end of each set of hydraulic cylinders is mounted on the worktable, and the other end of each set of hydraulic cylinders is mounted on the support frame. The third motor is mounted on the support frame, and the tensioning shaft is rotatably mounted on the support frame, with one end of the tensioning shaft connected to the output shaft of the third motor. The multiple sets of heating elements are installed inside the tensioning shaft, and the electrical connection wires of the multiple sets of heating elements extend from the shaft core at the other end of the tensioning shaft. Cashmere yarn is wound around the tensioning shaft, the third motor is turned on, and the tensioning shaft rotates to convey the cashmere yarn. Then, the tension of the cashmere yarn is adjusted by extending or contracting the multiple sets of hydraulic cylinders. At the same time, the multiple sets of heating elements heat the cashmere yarn on the tensioning shaft to dry the cashmere yarn, thereby improving the practicality of the equipment.

[0016] Preferably, the data analysis module includes:

[0017] Data classification unit: Classifies the received image data based on the positions of multiple cameras;

[0018] Deep learning processor: Using the PyTorch framework and convolutional neural network, it analyzes image data through a trained and qualified model, compares the analysis results with a set threshold, and determines that the cashmere yarn exceeds the threshold range as unqualified. It also makes an adjustment plan for the operating parameters of the cashmere yarn corona treatment equipment, and determines that the cashmere yarn is qualified if it is within the threshold range.

[0019] Database: Stores the training data for the model.

[0020] A method for treating cashmere yarn using a cashmere yarn corona treatment device, characterized by comprising the following steps:

[0021] S1. The cashmere yarn is wound onto the raw material shaft, then the cashmere yarn is wound around the tension shaft once, and then one end of the cashmere yarn is passed through the corona box, the first transparent tube, the second transparent tube, the cooling box and the detection box. Finally, one end of the cashmere yarn is fixed to the winding shaft.

[0022] S2. Turn on the first and second motors to loosen the cashmere yarn on the raw material shaft and wind it up on the winding shaft. Simultaneously, multiple sets of hydraulic cylinders extend or retract to adjust the tension of the cashmere yarn. Multiple sets of heating elements heat the cashmere yarn on the tensioning shaft to dry it. Then, turn on the exhaust pump and solenoid valve to discharge air into the air bladder ring, causing it to expand and narrow the inlet and outlet of the corona chamber, reducing air leakage. At the same time, the oxygen generator produces oxygen and discharges it into the air inlet pipe. The air intake fan also discharges air into the air inlet pipe, mixing the oxygen with the air before it enters the corona chamber. The corona head releases a high-voltage electric field inside the corona chamber to corona treat the cashmere yarn. The high-voltage electric field also converts the oxygen in the corona chamber into ozone.

[0023] S3. After corona treatment, the cashmere yarn enters the first and second transparent tubes. At the same time, ozone enters the first and second transparent tubes. The cashmere yarn is irradiated by ultraviolet lamps in the first and second light-shielding tubes. The ultraviolet light and ozone work together to treat the cashmere yarn and disinfect it. The circulation pump is turned on to draw ozone from the corona chamber into multiple sealing mechanisms. The sealing mechanisms cause the ozone to oxidize the cashmere yarn. Afterward, the circulation pump returns the ozone from the multiple sealing mechanisms to the corona chamber for reuse.

[0024] S4. The cashmere yarn inside the cooling box is cooled by a semiconductor cooling plate, and the cooling fan is turned on to dissipate heat from the semiconductor cooling plate.

[0025] S5. Multiple cameras capture images of the cashmere yarn, while multiple supplementary lights illuminate the cameras. A data classification unit categorizes the received image data based on the camera positions. A deep learning processor using the PyTorch framework and convolutional neural network analyzes the image data using a trained model, comparing the results with a set threshold. If the results exceed the threshold, the cashmere yarn is deemed unqualified. An adjustment plan for the operating parameters of the cashmere yarn corona treatment equipment is developed, and the operating speeds of the first and second motors are controlled to adjust the cashmere yarn processing speed. The length of the sealing mechanism is adjusted by controlling the extension or contraction of the cylinder. If the results are within the threshold range, the cashmere yarn is deemed qualified.

[0026] S6. After the test is completed, the winding shaft will wind up the cashmere yarn.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. By utilizing the ozone generated during the corona treatment process to further process cashmere yarn, the treatment effect of cashmere yarn is improved, while reducing the impact of ozone on the surrounding environment.

[0029] 2. By using deep learning processing methods in conjunction with the length adjustment of the sealing mechanism and the running speed of the conveying mechanism, it is convenient to adjust the operating parameters of the equipment during the cashmere yarn processing, thus ensuring the processing effect of the cashmere yarn.

[0030] 3. Before the equipment is put into operation, the oxygen content in the corona chamber is adjusted to increase the amount of ozone generated, which facilitates the oxidation treatment of cashmere yarn. The size of the inlet and outlet of the corona chamber is adjusted to reduce the diffusion of ozone. Attached Figure Description

[0066] The tensioning mechanism includes multiple sets of hydraulic cylinders 701, a support frame 702, a third motor 703, a tensioning shaft 704, and multiple sets of heating elements 705. One end of each set of hydraulic cylinders 701 is mounted on the worktable 101, and the other end of each set of hydraulic cylinders 701 is mounted on the support frame 702. The third motor 703 is mounted on the support frame 702.

[0067] The data analysis module includes:

[0068] Data classification unit: Classifies the received image data according to the positions of multiple cameras 602;

[0069] Deep learning processor: Using the PyTorch framework and convolutional neural network, it analyzes image data through a trained and qualified model, compares the analysis results with a set threshold, and determines that the cashmere yarn exceeds the threshold range as unqualified. It also makes an adjustment plan for the operating parameters of the cashmere yarn corona treatment equipment, and determines that the cashmere yarn is qualified if it is within the threshold range.

[0070] Database: Stores the training data for the model;

[0071] The cashmere yarn is wound onto the raw material shaft 401, then wound once around the tension shaft 704. One end of the cashmere yarn is then passed through the corona box 102, the first transparent tube 301, the second transparent tube 302, the cooling box 501, and the detection box 601. The other end of the cashmere yarn is then fixed to the winding shaft 402. The first motor 403 and the second motor 404 are turned on, causing the raw material shaft 401 to loosen the cashmere yarn and the winding shaft 402 to wind it up. Simultaneously, multiple sets of hydraulic cylinders 701 extend or retract to adjust the tension of the cashmere yarn. Multiple sets of heating elements 705 heat the cashmere yarn on the tension shaft 704 to dry it. Finally, the exhaust pump 106 and the solenoid valve 105 are turned on to vent air into the airbag. In ring 104, the airbag ring 104 expands, narrowing the inlet and outlet of the corona chamber 102 to reduce air leakage from the corona chamber 102. Simultaneously, oxygen is produced by the oxygen generator 205 and discharged into the air inlet pipe 203. Air is also discharged into the air inlet pipe 203 by the air intake fan 207, mixing oxygen and air before entering the corona chamber 102. A high-voltage electric field is released inside the corona chamber 102 through the corona head 103, corona treating the cashmere yarn. Simultaneously, the high-voltage electric field converts the oxygen in the corona chamber 102 into ozone. The corona-treated cashmere yarn enters the first transparent tube 301 and the second transparent tube 302, while ozone also enters the first transparent tube 301 and the second transparent tube 302. The ultraviolet lamps in the light-shielding tubes 303 and 304 irradiate the cashmere yarn, allowing the ultraviolet light to work in conjunction with ozone to treat the cashmere yarn. Simultaneously, the ultraviolet light disinfects and sterilizes the cashmere yarn. Meanwhile, the circulation pump 202 is activated, drawing ozone from the corona chamber 102 into multiple sealing mechanisms, where the ozone oxidizes the cashmere yarn. The circulation pump 202 then returns the ozone from the sealing mechanisms back to the corona chamber 102 for reuse. The semiconductor cooling plate 502 cools the cashmere yarn in the cooling chamber 501, while the cooling fan 503 dissipates heat from the semiconductor cooling plate 502. Finally, multiple cameras 602 capture images of the cashmere yarn, simultaneously... Multiple sets of supplementary lights 603 provide supplementary lighting for multiple sets of cameras 602. A data classification unit categorizes the received image data based on the positions of the multiple sets of cameras 602. A deep learning processor, employing the PyTorch framework and convolutional neural network, analyzes the image data using a trained model and compares the analysis results with a set threshold. If the data exceeds the threshold, it is determined to be unqualified cashmere yarn. An adjustment plan for the operating parameters of the cashmere yarn corona treatment equipment is then implemented. The operating speeds of the first motor 403 and the second motor 404 are controlled to adjust the cashmere yarn processing speed. The length of the sealing mechanism is adjusted by controlling the extension or retraction of the cylinder 305. If the length is within the threshold range, the cashmere yarn is determined to be qualified.The treated cashmere yarn is then wound up using the winding shaft 402.

[0072] A method for treating cashmere yarn using a cashmere yarn corona treatment device, characterized by comprising the following steps:

[0073] S1. The cashmere yarn is wound onto the raw material shaft 401, then the cashmere yarn is wound around the tension shaft 704 once, and then one end of the cashmere yarn is passed through the corona box 102, the first transparent tube 301, the second transparent tube 302, the cooling box 501 and the detection box 601, and then one end of the cashmere yarn is fixed on the winding shaft 402.

[0074] S2. Turn on the first motor 403 and the second motor 404, causing the raw material shaft 401 to loosen the cashmere yarn and the winding shaft 402 to wind up the cashmere yarn. At the same time, multiple sets of hydraulic cylinders 701 extend or retract to adjust the tension of the cashmere yarn, and multiple sets of heating elements 705 heat the cashmere yarn on the tensioning shaft 704 to dry the cashmere yarn. Then, turn on the exhaust pump 106 and the solenoid valve 105 to exhaust air into the airbag ring 104, causing the airbag ring 104 to inflate and affect the corona box 10. The feed inlet and discharge outlet of 2 are reduced to minimize air leakage from the corona chamber 102. At the same time, oxygen is produced by the oxygen generator 205 and discharged into the air inlet pipe 203. Simultaneously, air is discharged into the air inlet pipe 203 by the air intake fan 207, so that oxygen and air are mixed and enter the corona chamber 102. The high-voltage electric field is released inside the corona chamber 102 through the corona head 103 to corona treat the cashmere yarn. At the same time, the high-voltage electric field converts the oxygen in the corona chamber 102 into ozone.

[0075] S3. After corona treatment, the cashmere yarn enters the first transparent tube 301 and the second transparent tube 302. At the same time, ozone enters the first transparent tube 301 and the second transparent tube 302. The cashmere yarn is irradiated by ultraviolet lamps in the first light-shielding tube 303 and the second light-shielding tube 304. The ultraviolet light works with the ozone to treat the cashmere yarn and disinfect it. The circulation pump 202 is turned on to draw the ozone in the corona chamber 102 into multiple sealing mechanisms. The sealing mechanisms cause the ozone to oxidize the cashmere yarn. Afterward, the circulation pump 202 discharges the ozone in the multiple sealing mechanisms back into the corona chamber 102 for reuse.

[0076] S4. The cashmere yarn in the cooling box 501 is cooled by the semiconductor cooling plate 502, and the cooling fan 503 is turned on to dissipate heat from the semiconductor cooling plate 502.

[0077] S5. Multiple cameras 602 capture images of the cashmere yarn, while multiple supplementary lights 603 provide illumination for the cameras 602. A data classification unit categorizes the received image data based on the positions of the cameras 602. A deep learning processor using the PyTorch framework and convolutional neural network analyzes the image data using a trained model and compares the results with a set threshold. If the results exceed the threshold, the cashmere yarn is deemed unqualified. An adjustment plan for the operating parameters of the cashmere yarn corona treatment equipment is then implemented. The operating speeds of the first motor 403 and the second motor 404 are controlled to adjust the cashmere yarn processing speed. The length of the sealing mechanism is adjusted by controlling the extension or retraction of the cylinder 305. If the results are within the threshold range, the cashmere yarn is deemed qualified.

[0078] S6. After the test is completed, the winding shaft 402 winds up the cashmere yarn.

[0079] The main functions achieved by this invention are: improving processing efficiency, enhancing intelligence, and improving processing convenience;

[0080] 1. Improved treatment effect: Drying the cashmere yarn before corona treatment and then oxidizing it with ozone after corona treatment improves the overall treatment effect.
