[0028] The present invention provides a non-woven fabric yarn screening automatic unwinding device. First, when the unwinding box 101 is used, the reel 103 is loaded into the inner side through the installation slot 102, and the reel 103 is driven to rotate by the rotating shaft 104 to realize the unwinding function. The end of the yarn can be pressed between the rotating shaft pressure sensor 109 and the reel 103, and the pressing frame 108 and the rotating shaft pressure sensor 109 are further pressed by the telescopic cylinder 110, which is beneficial to realize the rotation through the pressing of the rotating shaft pressure sensor 109 after the yarn is released. When the rotating shaft pressure sensor 109 rotates with torque, it will realize the sensing effect, which is beneficial to ensure that the yarn is sensed whether it is released at the time of release. The connecting sleeve 106 is connected to the rotating shaft 104 through the plug-in seat 107, so as to facilitate quick installation and disassembly. The sliding rail bar 201 provides a guide installation for the sliding frame 202, which is convenient for the sliding frame 202 to realize the sliding adjustment function.

During the conveying process, the driving motor 210 drives the screw rod 209 to rotate, thereby driving the sliding block 207 to slide and connect to the inner side of the sliding track 208, ensuring the uniform delivery and release of the yarn, and effectively improving the stability and convenience of operation. When the yarn passes through the inside of the detection box 301, the mounting part 302 cooperates with the detector 303 to comprehensively detect the passing yarn, which is conducive to quickly discovering what problems exist in the yarn. When problems with the yarn are detected, the cylinder 402 on the lifting rail 401 pushes the two shearing knives 403 to perform shearing work, which is conducive to quickly processing the problematic yarn, thereby realizing the function of rapid screening and improving the efficiency of the operation. The guide roller 502 can accurately guide the yarn from the unwinding position to the subsequent processing or conveying position. During the unwinding process, after the yarn is released from the yarn roll, its direction may be chaotic. The guide roller 502 guides the yarn to a specific path through its own position and shape design to ensure that the yarn moves in the preset production process direction. During the yarn unwinding process, tension control is crucial. The yarn guide roller 502 can play a role in adjusting the yarn tension to a certain extent.
