Description

Technical Field

[0001] This application relates to the technical field of textile machinery, and particularly relates to an intelligent detector for detecting surface defects of fabrics in fabric factories and dyeing factories. Background Art

[0002] Fabric surface defect detection equipment is a set of essential special equipment for detecting extra-large-width, double-width, and single-width fabrics after production in textile industries such as fabric factories and dyeing factories. The fabric surface defect detection equipment provides a hardware environment for unfolding the fabric, provides sufficient light sources, and operators observe by eyesight to find the defects existing on the fabric surface and complete the fabric detection work.

[0003] Intelligent fabric defect detection equipment is equipped with an electronic defect detection device, and the detection results are statistically analyzed by a computer. It has a fast detection speed, high efficiency, and is very intelligent. For fabric factories and dyeing factories, after a series of operations such as dyeing and preheating of white greige fabrics, batch-folded fabrics are obtained. After defect detection, flawless fabrics are selected for shipment, while substandard fabrics are returned, and it is decided which process to start rework according to the fabric damage situation. Because of large-scale production, it is necessary to wind the fabrics into rolls for shipment at the time of shipment, which is convenient for shipment and thus provides goods sources for downstream garment factories. Therefore, there is an urgent need for an intelligent defect detection device for detecting surface defects of fabrics in fabric factories and dyeing factories.

[0004] Chinese Patent CN202220859389.5 discloses an integrated intelligent cloth inspection machine, which includes a weighing component, a unwinding component, a wire splitting component, a cloth inspection component, a walking platform, and a cloth discharging rack component. It can realize the dual-purpose feeding function of fabric rolls and folded fabrics. While visually detecting defects of the fabric, it provides color difference detection, mobile labeling, as well as weighing and width detection, covering the entire process of intelligent fabric detection, with a wide detection range and complete functions, greatly improving work efficiency, but it is mainly applicable to garment factories. Chinese Patent 202221547124.8 discloses an intelligent ramie cloth inspection machine, including a feeding device, a cloth feeding rack component, a ramie fabric detection device, a walking platform, and a cloth discharging rack component. When the cloth inspection machine is working, the ramie fabric enters the ramie fabric detection device for defect detection after passing through the feeding device and the cloth feeding rack component, and after manual auxiliary detection on the walking platform, the folded fabric is completed through the cloth discharging rack component. The working mode of this model also does not meet the usage requirements of fabric factories and dyeing factories for intelligent defect detection equipment. Summary of the Invention

As Figures 1 - 5 shown, an intelligent detector for detecting surface defects of fabrics in fabric factories and dyeing factories includes a fabric feeding rack assembly 1, a detection assembly 2, and a winding and weighing assembly 3. The fabric feeding rack assembly 1, the detection assembly 2, and the winding and weighing assembly 3 are sequentially movably connected. The fabric feeding rack assembly 1 includes a fabric feeding rack main body 4 and a fabric feeding rack column 5, and the fabric feeding rack main body 5 is located above the fabric feeding rack column 4. The detection assembly 2 includes a detection main body 15, a detection bracket 16, and a vision bracket 17. The vision bracket 17 is located below the detection bracket 16 and is perpendicular to the upper part of the detection main body 15. A vision main body (not shown in the figure) is flexibly installed on the vision bracket 17, and the vision main body includes an image acquisition device and a light source assembly. The winding and weighing assembly 3 includes a winding device 29 and a weighing device 30, and the winding device 29 is located above the weighing device 30. When the intelligent detector works, the fabric enters the detection area after passing through the fabric feeding rack assembly 1. After the surface defects of the fabric are detected, the winding and weighing of the fabric are completed through the winding and weighing assembly 3, meeting the requirements of fabric factories and dyeing factories for detecting fabric surface defects. In addition, the fabric feeding rack main body 4 is set at a high position through the fabric feeding rack column 5, which can save the floor area of the machine, facilitate the parking of fabric trucks in fabric factories and dyeing factories, and can also extend the time for the fabric to reach the detection assembly 2 to achieve a better deviation correction effect.

[0029] Figures 1 - 5In the [device name], a dust suction roller 6, a centering swing rod 7, a first fabric guiding roller 9 of the fabric inlet rack, a double yarn splitting roller 8, a second fabric guiding roller 10 of the fabric inlet rack, a third fabric guiding roller 11 of the fabric inlet rack, and a power mechanism 14 of the fabric inlet rack are arranged on the main body 4 of the fabric inlet rack. A fourth fabric guiding roller 12 of the fabric inlet rack and a fifth fabric guiding roller 13 of the fabric inlet rack are arranged on the upright column 5 of the fabric inlet rack. The dust suction roller 6, the centering swing rod 7, the first fabric guiding roller 9 of the fabric inlet rack, the double yarn splitting roller 8, the second fabric guiding roller 10 of the fabric inlet rack, the third fabric guiding roller 11 of the fabric inlet rack, the fourth fabric guiding roller 12 of the fabric inlet rack, and the fifth fabric guiding roller 13 of the fabric inlet rack are arranged in sequence along the fabric conveying direction. The power mechanism 14 of the fabric inlet rack is located on one side of the main body 4 of the fabric inlet rack. When the intelligent detector is working, the first fabric guiding roller 9 of the fabric inlet rack, the second fabric guiding roller 10 of the fabric inlet rack, the third fabric guiding roller 11 of the fabric inlet rack, the fourth fabric guiding roller 12 of the fabric inlet rack, and the fifth fabric guiding roller 13 of the fabric inlet rack are driven by the power mechanism 14 of the fabric inlet rack to convey the stacked fabric through the dust suction roller 6, the centering swing rod 7, and the double yarn splitting roller 8 in sequence. A dust suction port is arranged on the dust suction roller 6, and the dust suction port faces the fabric surface directly, which can remove dust, impurities, etc. on the fabric surface to obtain more accurate detection results and avoid interference of dust, impurities, etc. on the fabric surface with the detection. The centering swing rod 7 can correct the possible deviation during the fabric conveying process. The double yarn splitting roller 8 consists of two yarn splitting rollers, which are arranged side by side and closely attached, and the gap is slightly larger than the fabric thickness. Their threads are in reverse spiral from the middle line to both ends, and the thread directions of the left and right yarn splitting rollers are opposite, and their rotating directions are also opposite during work. The front yarn splitting roller provides the functions of guiding the fabric in and unfolding the curled edges, and the rear yarn splitting roller provides the functions of guiding the fabric out and unfolding the curled edges. After the fabric passes through the double yarn splitting roller 8, the curled edges on both sides of the fabric are unfolded on the premise of not damaging the fabric surface, making the fabric completely flat, achieving width expansion in a tension-free state, ensuring the stability of the fabric width, being conducive to the smooth progress of the work of the detection component 2, and making the detection result more accurate.

The fabric transmission assembly 18 in the detection area is located below the detection main body 15. The roll body 19 in the detection area, the swing rod rotating arm 20, the swing rod 21 in the detection area, the first fabric guide roller 22 in the detection area, and the second fabric guide roller 23 in the detection area are located on one side wall of the detection main body 15 close to the fabric feeding frame assembly 1. The third fabric guide roller 24 in the detection area and the fourth fabric guide roller 25 in the detection area are respectively located on both sides above the detection main body 15. The labeling device 26 and the operation console 27 are located above the detection main body 15. The walkway 28 is located on the right side of the detection main body 15.

There are two swing rod rotating arms 20, which are respectively rotatably sleeved at both ends of the roll body 19 in the detection area. The other ends of the two swing rod rotating arms 20 are internally sleeved with a swing rod 21 in the detection area parallel to the roll body 19 in the detection area. When the fabric enters the detection assembly 2 through the fabric feeding frame main body 4, it passes through the roll body 19 in the detection area and the swing rod 21 in the detection area in sequence. Through the rotational swing of the swing rod rotating arm 20 on the roll body 19 in the detection area, the function of smooth fabric transmission is achieved, and then it passes through the transmission of the first fabric guide roller 22 in the detection area, the second fabric guide roller 23 in the detection area, the third fabric guide roller 24 in the detection area, and the fourth fabric guide roller 25 in the detection area in sequence to complete the defect detection task. The labeling device 26 is used for labeling the detected defects (this is the prior art and will not be elaborated). The operation console 27 completes the interaction with the server through the network, receives or sends data, messages, etc. Corresponding applications are installed on the interface, and the specific detection results can be displayed. A walkway 28 is set on the right side of the detection main body 15 to facilitate the staff to conduct a re-inspection. The staff can stand on the walkway 28 to conduct an artificial re-inspection on the fabric that has been detected and labeled.
