Description

Technical Field

[0001] This invention relates to the field of sizing machine technology, specifically a sizing machine based on a segmented rigid frame. Background Technology

[0002] Sizing is a crucial pre-weaving process, and the performance of the sizing machine directly affects yarn strength, abrasion resistance, and subsequent weaving efficiency. Traditional sizing machines based on segmented rigid frames, while having the advantages of structural stability and easy modular layout, have significant limitations in real-time detection and intelligent control of key yarn process conditions. Currently, tension detection in sizing segments mostly relies on contact rollers or swing arm mechanisms, which are easily affected by sizing liquid adhesion, mechanical wear, and environmental vibration, leading to measurement drift and insufficient accuracy, making it difficult to achieve high-precision closed-loop control.

[0003] Yarn breakage detection generally uses photoelectric or mechanical baffle sensors, which have a high rate of false alarms and missed alarms under harsh working conditions such as high temperature and humidity and slurry mist, and cannot locate the break point, affecting processing efficiency. In addition, existing technologies lack the ability to perceive deep quality information such as yarn micro vibration and slurry film formation state, and the data of each process section are isolated, making it impossible to form a collaborative optimization.

[0004] Therefore, there is an urgent need for an innovative solution that can adapt to the complex environment of the sizing room and achieve reliable perception and intelligent control of multi-dimensional status, so as to break through the existing technical bottlenecks and improve the stability of sizing quality and production efficiency.

[0031] Example 1:

[0032] Please see Figures 1-6 The present invention discloses a sizing machine based on a segmented rigid frame, comprising a main frame 10; a control cabinet 20 with adjustment function is fixedly installed on the side of the main frame 10 by bolts; the main frame 10 also includes a feeding section 11, a sizing section 12 disposed behind the feeding section 11, and a shaping section 13 disposed behind the sizing section 12; the sizing section 12 specifically consists of a sizing trough for sizing, multiple sets of rollers rotatably disposed in the sizing trough, and an adjustment frame 121 fixedly installed on the outer side of the sizing trough, and a housing is also provided on the adjustment block of the adjustment frame 121; an integrated detection component 122 and a single controller for data processing are fixedly installed inside the housing of the adjustment frame 121.

[0033] The integrated detection component 122 includes a pressure cylinder 21 fixedly installed on the left and right inner walls of the adjusting frame 121 housing; a bearing seat assembly 22 with a buffering function is inserted and fixedly installed at the end of the piston rod of the pressure cylinder 21; a rotary joint 24 is rotatably installed inside the bearing seat assembly 22, and the rotary joint 24 is rotatably installed at the air holes on the left and right sides of the tension roller 23; an air film assembly 25 is laid flat inside the tension roller 23, and air holes are opened on the surface of the tension roller 23; an induction beam 26 is fixedly installed on the side of the bearing seat assembly 22 by bolts; a demodulation device 27 with data processing function is fixedly installed on the side of the induction beam 26 by bolts.

[0034] The bearing housing assembly 22 includes a combined housing 221 that is plugged into and fixedly installed at the end of the piston rod of the pressure cylinder 21; a pressure sensor 222 is fixedly installed at the bottom of the combined housing 221 by bolts; the sensing head of the pressure sensor 222 is fixedly installed on the side of the sliding frame 223, and the sliding frame 223 is slidably disposed inside the combined housing 221; a three-dimensional force sensor 224 is integrated on the side of the sealing plate of the sliding frame 223, and the sealing plate of the sliding frame 223 is fixedly installed on the side of the fixing ring of the bearing component 225.

[0035] The sensing beam 26 is also equipped with a high-temperature resistant single-mode optical fiber for detection, which is laid flat in an S-shape inside the side plate of the sensing beam 26; air jets are also provided on the upper and lower sides inside the sensing beam 26 to provide a dry and clean micro-positive pressure airflow to purge the inside of the sensing beam 26 and prevent condensation and slurry intrusion.

[0036] The laying path of the high-temperature resistant single-mode optical fiber inside the sensing beam 26 is a redundant ring loop covering the upstream and downstream areas of the tension roller 23; the demodulation device 27 is a distributed acoustic wave sensor demodulator, which continuously spatially locates and captures abnormal acoustic wave events by detecting the yarn running status of the tension roller 23 section.

[0037] Pressure cylinders 21 and corresponding sensing beams 26 and demodulation devices 27 are also installed between the sizing section 12 and the shaping section 13, as well as inside the shaping section 13, thereby forming a distributed multi-node detection network in multiple key process sections of the sizing machine; the intelligent edge computing unit of each node communicates with the main control system in the control cabinet 20.

[0038] The tension roller 23 forms a closed-loop air circuit system with the two sets of rotary joints 24 on its left and right sides; the tension roller 23 is equipped with a temperature and humidity sensor for gas composition detection.

[0039] Example 2:

[0040] Please see Figures 1-6 The present invention provides a sizing machine based on a segmented rigid frame. Compared with Embodiment 1, this embodiment further includes: an air film assembly 25 comprising a high-temperature resistant air guiding membrane 251 laid flat inside the tension roller 23, and an array of fine-pore silicone heads 252 arranged on the outer surface of the high-temperature resistant air guiding membrane 251; the fine-pore silicone heads 252 are pressed into and fixed in the air holes provided on the tension roller 23, and micro-air holes are opened on the fine-pore silicone heads 252; a square block is also provided inside the fine-pore silicone heads 252, and a permanent magnet rod 253 is inserted and fixed on the square block; a magnetic field sensor 254 with data sensing function is also integrated and fixed on the high-temperature resistant air guiding membrane 251, and the magnetic field sensor 254 is connected to a single controller inside the adjusting frame 121 through an integrated cable 255 provided on the high-temperature resistant air guiding membrane 251.

[0041] The magnetic field sensor 254 integrated within the high-temperature resistant air-conducting membrane 251 is specifically a high-sensitivity magnetostrictive displacement sensor array, used to calculate the micro-vibration state of the yarn on the air membrane by sensing the micro-displacement of the permanent magnet rod 253.

[0042] The working principle of a sizing machine based on a segmented rigid frame, as described above, is as follows:

[0043] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0044] Secondly, the gas system set in the control cabinet 20 and the main frame 10 allows clean gas with precise temperature and humidity control to enter the tension roller 23 through the rotary joint 24. The gas enters the fine-pore silicone head 252 through the high-temperature resistant air guide membrane 251 and is sprayed out from the micro-pores on its surface to achieve uniform seepage on the roller surface and form an extremely thin and uniform air film. The yarn is slightly lifted by this air film to achieve non-contact suspension transmission.

[0045] Third, the yarn tension is transmitted to the tension roller 23 through the air film pressure field, and the force is applied to the bearing seat assembly 22 at both ends. The triaxial force sensor 224 integrated inside the assembly realizes direct tension sensing, while the pressure sensor 222 monitors the floating buffer state. At the same time, the magnetic field sensor 254 integrated in the high-temperature resistant air guiding membrane 251 continuously monitors the micro-displacement of the permanent magnet rod 253. Any jump, hair disturbance or abnormal vibration of the yarn will cause changes in the air film flow field and squeeze the fine-pore silicone head 252, thereby causing the permanent magnet rod 253 to move and be captured by the magnetic field sensor 254 to form a vibration spectrum signal to realize micro-vibration sensing. The high-temperature resistant single-mode optical fiber laid in the sensing beam 26 also detects abnormal conditions of yarn and related airflow disturbances. This data is analyzed by the demodulation device 27 and the abnormal conditions of yarn upstream and downstream of the tension roller 23 are detected in real time.

[0046] Fourth, the data from the pressure sensor 222, the three-dimensional force sensor 224, and the magnetic field sensor 254 are transmitted in real time to the computing unit of the unit controller or control cabinet 20. When the optical fiber detects abnormal sound waves, the algorithm immediately checks whether the tension of the pressure sensor 222 and the three-dimensional force sensor 224 drops suddenly and whether the vibration spectrum has impact characteristics at the same time. After the three signals are spatiotemporally correlated and their characteristics are matched, it is determined to be a yarn breakage state. The fluctuation trend of the tension curve is analyzed in real time. The pressure cylinder 21 is also used to finely adjust the clamping force or position of the tension roller 23 to compensate for tension fluctuations in real time.

[0047] This invention provides an improved sizing machine based on a segmented rigid frame. The air film suspension formed by the air film assembly 25 eliminates contact friction interference, making tension measurement extremely accurate and stable. Furthermore, by integrating the bearing housing assembly, the air film assembly 25, and the sensing beam 26 to perform three-dimensional collaborative judgment of tension drop, vibration impact, and acoustic signals, the accuracy of yarn breakage identification is improved, thereby actively suppressing tension fluctuations, ensuring uniform sizing, and significantly reducing yarn breakage and raw material waste.
