DETAILED DESCRIPTION
[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts are within the scope of protection of the present invention.
[0017] like Figures 1 to 5 As shown, the present application provides a double-sided circular knitting machine fabric inspection device, which includes: an image acquisition module 1, a first connecting bracket 2, a first clamping structure 3, a second clamping structure 4, an adjustment tube assembly 5 and a first adjustment plate 6.
[0018] Specifically, the first connecting bracket 2 is disposed through the central passage of the double-sided circular knitting machine and extends into the interior of the machine. The first clamping structure 3 is disposed within the machine and is movable along the axial direction of the first connecting bracket 2 and can be clamped and fixed in a predetermined position to adjust the longitudinal position of the image acquisition module 1.
[0019] The second clamping structure 4 is hingedly mounted on the first clamping structure 3 and can be adjusted in pitch angle relative to the horizontal plane.
[0020] The adjustment tube assembly 5 includes a sleeve 51, a slide rod 52, and a locking member 53. The sleeve 51 is rotatably mounted about its axis within the second clamping structure 4. The slide rod 52 is slidably inserted into the sleeve 51 and secured by the locking member 53. This allows the image acquisition module 1 to be positioned axially along the slide rod 52, maintaining a capture distance of 5 to 20 cm from the fabric surface and improving image quality. The slide rod 52 is provided with a slot 521 along its axial direction. The locking member 53, after being inserted through the sleeve 51, engages within the slot 521, securing the slide rod 52.
[0021] The first adjustment plate 6 has a mounting base 7 at its base. Mounting base 7 is attached to the slide slot 521 via a rotary connection structure, allowing for adjustment of the angle of the mounting base within its plane. The rotary connection structure comprises a through-hole in the plate surface and an arcuate slot surrounding the through-hole. Screws pass through the through-hole to secure the plate, and an adjustment nut is positioned within the arcuate slot. Adjusting the position of the adjustment nut within the arcuate slot allows for adjustment of the plate's mounting angle. The first adjustment plate 6 is hingedly mounted to the mounting base 7, allowing for pitch adjustment relative to the mounting base 7.
[0022] The image acquisition module 1 is mounted on the first adjustment plate 6 and fixed by a plurality of fastening bolts.
[0023] The above-mentioned configuration, through a multi-dimensional adjustment structure, enables the image acquisition module 1 to achieve precise control of all-round angles and positions, greatly improving the imaging clarity and image coverage of the inspected fabric. At the same time, the modular structural design improves the system's assembly convenience and maintenance efficiency, facilitating adaptation and modification on different models of double-sided circular knitting machines. Furthermore, the adjustment mechanism can be quickly locked and stably positioned, exhibiting excellent shock resistance and durability in industrial environments, ensuring reliability for long-term use. Furthermore, through the rational arrangement of sliding and rotating connections, the degree of adjustment freedom is increased while the complexity of the mechanism is reduced, achieving intuitive and efficient adjustment operations.
[0024] like Figure 4 As shown, the first clamping structure 3 includes a first tube clamp 31 that is sleeved on the first connecting bracket 2 and a first connecting plate 32 installed on the first tube clamp 31; the second clamping structure 4 includes a second connecting plate 41 and a second tube clamp 42 installed at the bottom of the second connecting plate 41, and the second tube clamp 42 is sleeved on the sleeve 51; the first connecting plate 32 and the second connecting plate 41 are both L-shaped plates, and the short side of the first connecting plate 32 and the short side of the second connecting plate 41 are connected by a rotating connection structure. This design achieves an organic combination of structural strength and adjustable flexibility by using a standardized L-shaped connecting plate structure. At the same time, the rotating connection structure enables the second clamping structure 4 to have a pitch angle adjustment function, thereby increasing the posture adjustment range of the image acquisition module 1. In addition, the sleeve installation method of the first tube clamp 31 and the second tube clamp 42 is simple and firm, facilitating subsequent maintenance or module replacement, and reducing maintenance costs.
[0025] like Figure 2 and Figure 4 As shown, the cloth inspection device also includes a fixed structure 8 provided on the top cover of the double-sided circular machine, and the fixed structure 8 includes a fixed flange 81, a fixed ring 82 and a limit plate 83. The fixed flange 81 is mounted on the top of the first connecting bracket 2 to fix the installation height of the first connecting bracket 2. The fixed ring 82 is mounted on the first connecting bracket 2, and the limit plate 83 is installed on the top surface of the fixed flange 81. The limit plate 83 and the fixed ring 82 are passed through a long screw for limiting cooperation, which can limit the rotation of the first connecting bracket 2 around its axis. This setting provides a reliable bracket installation method, effectively ensuring that the position of the image acquisition module 1 does not shift during the detection process, thereby improving imaging consistency and measurement accuracy. At the same time, the limiting structure is simple and compact, easy to assemble and adjust, and suitable for adjustment requirements of different installation heights and angles. In addition, rotation suppression is achieved by adopting a mechanical limiting method to avoid system errors caused by vibration or external forces, thereby improving overall operational reliability.
[0026] The first connecting bracket 2 is a hollow structure with a wire outlet 21 at the lower end of the side for the air supply to pass through. The hollow structure enables internal wiring, effectively protecting the air circuit from external mechanical damage, improving system safety and reliability. At the same time, the integrated wiring function reduces the amount of exposed external air circuits, improving the overall aesthetics and compactness of the equipment. like Figure 2 and Figure 3 As shown, a waste oil collection bottle 9 is fixed to the lower end of the first connecting bracket 2. It is used to collect waste oil generated by the double-sided circular knitting machine, thereby effectively improving the cleanliness of the equipment operating environment and preventing the spread of lubricating oil or waste oil from contaminating the equipment and surrounding areas. At the same time, it facilitates the centralized management and treatment of waste oil, meets environmental protection requirements, and realizes resource recovery.
[0027] Above the waste oil collection bottle 9, a rotating slip ring 10 is mounted on the first connecting bracket 2. The sidewalls of the rotating slip ring 10 are equipped with an oil inlet 101 and an oil outlet 102 for oil flow, as well as an air inlet 103 and an air outlet 104 for air flow. The structure of the rotating slip ring 10 effectively achieves flexible adaptation of the oil and air circuits during bracket rotation, improving the stability and safety of the wiring system. Furthermore, the provision of independent inlet and outlet channels improves the orderly management of oil and cable circuits and reduces the risk of cross-interference.
[0028] like Figure 2 As shown, a cloth support frame 20 is installed at the bottom of the first connecting bracket 2 to form a stable cloth surface to be detected, thereby enhancing the stability of the cloth surface before image acquisition and significantly improving the imaging quality and the accuracy of subsequent image processing.
[0029] like Figure 1 and Figure 5 As shown, the cloth inspection device also includes an image processing module 30 and a second connecting bracket 40. The image processing module 30 is installed on the top mounting ring of the double-sided circular knitting machine through the second connecting bracket 40, so that the image processing module 30 has good adjustment capabilities and can cope with different height and angle requirements, thereby achieving more efficient and accurate image analysis and processing.
[0030] Specifically, the second connecting bracket 40 includes a fixed connecting structure 401, a connecting rod 402 and a second adjustment plate 403. The fixed connecting structure 401 is used to be fixed on the mounting ring. The connecting rod 402 is installed at the bottom of the fixed connecting structure 401 and extends in the vertical direction. The connecting rod 402 is provided with a mounting groove along its extension direction. The second adjustment plate 403 is slidably set on the mounting groove, and the image processing module 30 is mounted on the adjustment plate 403 by screws provided on the back thereof. By providing a sliding mounting groove, the height of the image processing module 30 can be quickly adjusted, thereby improving adjustment efficiency and ease of operation. In addition, the above-mentioned connecting mechanism has a compact structure and strong stability, and is suitable for long-term industrial operation environments.
