Technical Field
[0001] This utility model relates to the field of nonwoven fabric production technology, specifically a hot air nonwoven fabric rapid inspection device. Background Technology
[0002] In the field of nonwoven fabric production technology, especially in the production of hot-air nonwoven fabrics, fabric quality inspection is a crucial step. Traditional inspection methods mainly rely on manual visual inspection, which is not only inefficient and unable to meet the needs of large-scale production, but also susceptible to human factors such as fatigue and lack of concentration, leading to missed or false inspections, seriously affecting product quality and production efficiency. While some automated fabric inspection equipment has emerged with the development of automation technology, these devices are often complex in structure and expensive, making them unaffordable for small and medium-sized enterprises. Furthermore, existing equipment still suffers from insufficient accuracy in detecting minute defects, especially in the production of hot-air nonwoven fabrics with their unique structure, where the requirements for inspection devices are even higher. Therefore, developing a high-efficiency and cost-effective rapid fabric inspection device for hot-air nonwoven fabrics has become an urgent need in the industry. Utility Model Content
[0003] The purpose of this invention is to provide a rapid hot air nonwoven fabric inspection device to solve the problems mentioned in the background art.

[0021] Please see Figures 1-4 In this embodiment of the invention, a rapid hot air nonwoven fabric inspection device includes two parallel fixed plates 1. A detection box 3 is fixedly connected to the top of one end of each of the two fixed plates 1. A base plate 5 is fixedly connected to the bottom of the detection box 3. A detection groove 4 is formed between the detection box 3 and the base plate 5. A bottom groove 13 is formed at the bottom of the detection box 3, and an X-ray transmission sensor 14 is fixedly connected to the bottom of the bottom groove 13.
[0022] A motion roller 6 is installed at the end of the two fixed plates 1 away from the detection box 3, and a bottom roller 7 is installed at the bottom of the two fixed plates 1 near the motion roller 6. A detection sensor 12 is embedded and fixedly connected to the side wall of the two fixed plates 1 near the bottom roller 7, and the horizontal height of the detection end of the detection sensor 12 is higher than the horizontal height of the top of the bottom roller 7.
[0023] Each of the two fixed plates 1 has a motion groove 9 inside near one end of the motion roller 6, and the two motion grooves 9 are through-holes near the end of the motion roller 6. A linear motor 10 is movably connected to the inner wall of each of the two motion grooves 9, and a connecting block 11 is fixedly connected to one end of each of the two linear motors 10 near the end of the motion roller 6. The two connecting blocks 11 are movably connected through the motion grooves 9 that match their positions.
[0024] Both ends of the motion roller 6 are fixedly connected to movable bearing 61, and both movable bearing 61 are fixedly connected to the side wall of the connecting block 11 that matches the position.
[0025] Both ends of the bottom roller 7 and the discharge roller 8 are fixedly connected to fixed bearings 71, and multiple fixed bearings 71 are embedded and fixedly connected to the side walls on both sides of the fixed plate 1.
[0026] A controller 2 is fixedly connected to one side wall of each of the two fixed plates 1, which is used to control the operation of the entire device. Fixing ears are fixedly connected to the bottom side walls of the two fixed plates 1, which are far apart from each other, to facilitate the installation and fixation of the device.
[0027] The X-ray transmission sensor 14 is used to detect the weight deviation of the hot air nonwoven fabric, and the weight per square meter is controlled within ±3%. The detection principle is well known to those skilled in the art. The X-ray transmission sensor 14 can be SPOT type or LINE type. The control terminal of the X-ray transmission sensor 14 is electrically connected to the signal terminal of the controller 2. The controller 2 can be selected as a PLC programmable controller to ensure that the whole device can operate stably.
[0028] Meanwhile, multiple industrial cameras can be installed inside the bottom groove 13 to work with corresponding detection programs, thereby improving the detection effect and upgradeability of the device.
[0029] The working principle of this invention is as follows: First, the hot-air nonwoven fabric to be tested is introduced into the detection groove 4 through the moving roller 6 and the bottom roller 7. As the nonwoven fabric moves, the X-ray transmission sensor 14 starts to work, performing high-precision detection of the weight deviation of the nonwoven fabric.
[0030] The X-rays emitted by the X-ray transmission sensor 14 penetrate the nonwoven fabric and are received by the receiver at the bottom, converted into an electrical signal. This signal is processed to obtain the basis weight data of the nonwoven fabric, which is then compared with a preset standard value to determine whether there is a basis weight deviation. Simultaneously, the detection sensor 12 monitors the passage of the nonwoven fabric in real time to ensure stable operation during the detection process.
[0031] When the nonwoven fabric experiences abnormal conditions such as tape breakage or blockage, the detection sensor 12 will immediately send a signal to the controller 2. The controller 2 will then control the linear motor 10 to adjust the position of the motion roller 6 to restore the normal operation of the nonwoven fabric or stop the device from operating, thus preventing equipment damage.
[0032] Furthermore, multiple industrial cameras can be installed inside the bottom groove 13, working in conjunction with corresponding detection programs to further inspect surface defects in the nonwoven fabric, improving the device's detection effectiveness and upgradeability. Through this comprehensive inspection method, the hot-air nonwoven fabric rapid inspection device of this invention can achieve efficient inspection of hot-air nonwoven fabrics, providing reliable quality assurance for nonwoven fabric production.
