Description

Technical Field

[0001] The present invention relates to the technical field of chemical fiber yarn paper tube detection, and particularly to an appearance rotation detection device for chemical fiber yarn paper tubes. Background Art

[0002] During the production and application of chemical fiber yarn paper tubes, their appearance quality has a crucial impact on the subsequent winding, storage, and use of chemical fiber yarns. However, currently, many challenges are faced when detecting chemical fiber yarn paper tubes.

[0003] On the one hand, most of the existing detection devices use a single-axis rotation method to detect paper tubes. This detection method has obvious limitations. It can only detect some areas on the surface of the paper tube, and it is often difficult to capture defects in hidden areas such as the cylinder seam and the end face. For example, there may be defects such as gaps, overlaps, or insecure bonding at the seam of the paper tube due to production processes. The single-axis rotation detection method is likely to miss these problems. Moreover, the end face of the paper tube may also be deformed or damaged, and the same cannot be fully detected. This results in many paper tubes with potential quality problems flowing into the market, bringing potential hazards to the production and use of chemical fiber yarns.

[0004] On the other hand, with the continuous development of the materials used in chemical fiber yarn paper tubes, new composite materials are gradually widely used. However, the existing detection devices usually use a fixed-wavelength light source for detection. This light source cannot be adjusted according to the characteristics of new composite materials and is difficult to cope with the characteristic spectrum recognition of these materials. Different new composite materials have different spectral characteristics. The fixed-wavelength light source may not be able to accurately identify defects and abnormalities inside the materials, thus reducing the detection effect. Therefore, we propose an appearance rotation detection device for chemical fiber yarn paper tubes to solve the above problems. Summary of the Invention

Detailed implementation manner

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0032] Refer to Figure 1-6 , a rotating detection device for the appearance of chemical fiber paper tubes, including a protection box 21. Walking mechanisms are provided on both sides of the protection box 21. Lifting mechanisms are fixed on both sides of the protection box 21. A protection box 2 is installed at the upper end of the lifting mechanism. A reciprocating movement mechanism is arranged in the protection box 2. A rotating device is installed on the reciprocating movement mechanism. The lower end of the rotating device is connected to a U-shaped detection frame 6. A detection mechanism is installed on the U-shaped detection frame 6. An expansion mechanism is arranged in the protection box 21. A support structure is installed at the upper end of the expansion mechanism. The support structure corresponds to the detection mechanism. Through the coordinated work of each mechanism, a comprehensive detection of the appearance of chemical fiber paper tubes of different specifications is realized;

[0033] The walking mechanism includes track wheels 11 rotatably connected to both ends of both sides of the protection box 21. A second servo motor 30 is installed on one side inside the protection box 21. The end of the output shaft of the second servo motor 30 is connected to one side of one of the track wheels 11 through a second reduction box 31. A track 16 is provided at the lower ends of the two track wheels 11 on the same side. The two track wheels 11 on the same side are clamped on one track 16 on the same side. The second servo motor 30 provides power, and the speed is reduced and the torque is increased through the second reduction box 31 to ensure that the track wheels 11 can move stably and accurately on the track 16. The setting of the track 16 provides a clear path for the movement of the device and ensures the accuracy of the device position during the detection process;

[0034] The lifting mechanism includes vertical plates 10 fixed on both sides of the track 16. A chute 19 is provided on one side of the vertical plate 10. A first slider 1 is installed in the chute 19. A support plate 9 is fixedly connected between the two first sliders 1. A first hydraulic cylinder 15 is provided on one side of the vertical plate 10. The end of the piston rod of the first hydraulic cylinder 15 is fixed to the lower end of the support plate 9. The lower end of the protection box 2 is fixed to the upper end of the support plate 9. The first hydraulic cylinder 15 serves as a power source. When the piston rod expands and contracts, it drives the support plate 9 to move up and down along the chute 19. The cooperation between the chute 19 and the first slider 1 ensures the stability and linearity of the movement of the support plate 9. Through the lifting mechanism, the detection mechanism can be adjusted to an appropriate height to accurately correspond to the position of the paper tube to be detected, meeting the detection requirements of paper tubes of different heights;

[0035] The reciprocating movement mechanism includes a fourth servo motor 33 installed on one side inside the protection box 2.

A second slider 36 is penetrated through the guide rod 34, and the second slider 36 is screwed onto the stud 35. The fourth servo motor 33 drives the stud 35 to rotate. Since the second slider 36 is threadedly connected to the stud 35 and is guided by the guide rod 34, the second slider 36 will perform a linear reciprocating movement on the stud 35, which can accurately control the reciprocating movement of the detection mechanism to achieve a full monitoring of the circumference of the paper tube and ensure the comprehensiveness of the detection;

[0036] The rotating device includes a mounting plate 37 fixed to the upper end of the second slider 36. A first reduction box 4 is installed on the upper end of the mounting plate 37. One end of the first reduction box 4 is connected to a first servo motor 5. First openings 3 are provided at both the upper and lower ends of the protection box 2.

A transmission shaft is connected inside the first reduction box 4. The lower end of the transmission shaft penetrates through the side wall of the second slider 36 and the third opening 29 and is fixed to the upper end of the U-shaped detection frame 6. The first servo motor 5 provides power. After being decelerated and torque-increased by the first reduction box 4, the transmission shaft drives the U-shaped detection frame 6 to rotate. The settings of the first opening 3 and the third opening 29 provide space for the rotation of the transmission shaft, enabling the U-shaped detection frame 6 to rotate flexibly by 90 degrees, so that the detection mechanism corresponds to the two end faces of the paper tube to achieve the detection of the end faces of the paper tube;

[0037] The detection mechanism includes cylinders 7 fixed on both sides of the U-shaped detection frame 6. A T-shaped sliding groove 32 is provided at the upper end of the U-shaped detection frame 6. Two carrier frames are slidably connected in the T-shaped sliding groove 32. A detection device 8 is installed on the carrier frames. The piston rod of one cylinder 7 on the same side is connected to one end of the carrier frame on the same side. The detection device 8 includes a tunable laser source, a polarization imaging module, and a confocal microscopy unit. The cylinder 7 drives the carrier frame to slide in the T-shaped sliding groove 32, thereby adjusting the position of the detection device 8. The tunable laser source can emit lasers of different wavelengths for detecting different characteristics of the paper tube. For example, the resin impregnation uniformity is detected by short-wave infrared. The polarization imaging module can capture abnormal fiber orientation and analyze the arrangement of internal fibers of the paper tube by using the polarization characteristics of light. The confocal microscopy unit can perform microscopic detection on the surface of the paper tube to discover tiny defects, achieving full monitoring of the new material;

[0038] The expansion mechanism includes a support frame 26 fixed in the middle of the protection box 21. Two rotating arms 25 are rotatably connected to both sides of the support frame 26. Four second hydraulic cylinders 27 are rotatably connected to the support frame 26. The piston rod of one second hydraulic cylinder 27 on the same side is rotatably connected to one end of the rotating arm 25 on the same side. One side of the rotating arm 25 is rotatably connected to a rotating rod 24. One end of the two rotating rods 24 on the same side is jointly rotatably connected to a moving plate 23. Two slide rails 22 are provided on both sides of the lower end of the protection box 21. Both sides of the lower end of one moving plate 23 on the same side are slidably connected to the two slide rails 22 on the same side. The second hydraulic cylinder 27 serves as the power source of the expansion mechanism. When the piston rod expands and contracts, it drives the rotating arm 25 to rotate. The rotating arm 25 drives the moving plate 23 to slide on the slide rail 22 through the rotating rod 24, enabling the expansion mechanism to expand according to the parameters of paper tubes of different specifications and adjust the position and spacing of the support structure to meet the detection requirements of paper tubes of different sizes;

[0039] The support structure includes a connection block 28 fixed on the upper end of the moving plate 23. A second opening 12 is provided in the middle of the upper end of the protection box 21. The connection block 28 passes through the second opening 12 and extends to the upper end of the protection box 21. An installation frame 13 is fixed to the upper end of the connection block 28. Two support wheels 14 are rotatably connected to one side of the installation frame 13. A third servo motor 20 is installed on one side of one of the installation frames 13. The output shaft of the third servo motor 20 is connected to one end of one of the support wheels 14. The third servo motor 20 drives the support wheel 14 to rotate, thereby driving the paper tube placed on the support wheel 14 to rotate. The setting of the support wheel 14 provides stable support for the paper tube and can ensure the smooth rotation of the paper tube during the detection process, facilitating the detection mechanism to perform a comprehensive detection on the paper tube;

[0040] An induction block 17 is installed on one side of the protection box 21, and a corresponding proximity switch 18 is provided on one side of the induction block 17.

[0041] In the present invention, first, the expansion mechanism expands according to parameters of different specifications, enabling the device to adapt to the paper tube detection requirements of different sizes. By the telescopic movement of the second hydraulic cylinder 27, the position of the moving plate 23 is adjusted, thereby changing the spacing and position of the support structure. Then, the paper tube is transferred to the support structure by the vacuum adsorption arm. The vacuum adsorption arm can stably and accurately place the paper tube on the support wheel 14, ensuring the accurate placement position of the paper tube. The proximity switch 18 issues an instruction to drive the entire protection box 21 to move through the traveling mechanism. After accurately moving to the lower end of the detection mechanism, the lifting mechanism drives the detection mechanism to descend to the corresponding position, so that the two arc surfaces of the corresponding paper roller are in a certain state. In this process, the induction block 17 and the proximity switch 18 cooperate with each other to achieve precise control of the device movement. The support mechanism drives the paper tube to rotate, and the reciprocating movement mechanism drives the detection mechanism to reciprocate, achieving full monitoring of one week. Then, the rotating device drives the detection mechanism to rotate 90 degrees so that it corresponds to the two end faces of the paper tube, and the traveling mechanism moves to conduct full monitoring of the two end faces. During the detection process, the detection device 8 plays an important role. The short-wave infrared is used to detect the resin impregnation uniformity. By detecting the absorption and reflection of infrared light of different wavelengths in the paper tube, it is judged whether the resin impregnation is uniform. The ultraviolet fluorescence is used to identify the absence of the nano-coating. By utilizing the fluorescence characteristics of the nano-coating under ultraviolet light, it is detected whether the coating is missing. The polarization imaging is used to capture the abnormal fiber orientation. Based on the defect classification model of deep learning, the grade determination is output in real time, providing a basis for subsequent processing.

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, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
