The corrected raw material will pass Detector 4, detector 4 adopts intelligent laser triangulation displacement sensor optoNCDT1420, detector 4 detects the length of raw materials by laser, and then transmits the detected data to external equipment, and then the external equipment controls the cylinder 2 702 on both sides to move, and when the cylinder 2 702 extends, the top plate 701 will be pushed out from the gap between the rollers 3, so that the raw materials roll to the inside of the discharge plate 8, and are collected by the external collection box, so that one of the two cylinders 2 702 is controlled by the external equipment to classify raw materials of different lengths, and the raw materials can be quickly classified through the ejection mechanism 7, thereby reducing the inconvenience caused by personnel classification.

[0024] like Figure 3As shown, the correction mechanism 6 includes a cylinder 1 601, a rotating plate 602, a connecting rod 603, a push rod 604 and a splint 605. The cylinder 1 601 is provided with two symmetrical left and right parts, and the push rod 604 is provided with two symmetrical front and back parts. The output end of the cylinder 1 601 is fixedly connected to the bottom end of one of the push rods 604, the top end of the push rod 604 is fixedly connected to the top end of the splint 605, and the top end of the push rod 604 is movably connected to the inside of the gap of the roller shaft 3. One end of the connecting rod 603 is hinged to the bottom end of the push rod 604, and the other end of the connecting rod 603 is respectively hinged to one side of the top end of the rotating plate 602. The cylinder 1 601 is fixedly connected to the top end of the support plate 5, the rotating plate 602 is rotatably connected to the top end of the support plate 5, the splint 605 is movably connected to the top end of the roller shaft 3, the top end of the support plate 5 is fixedly connected to the slide rail 9, and the top end of the slide rail 9 is slidably connected to the slider 10, and the top end of the slider 10 is fixedly connected to the bottom end of the push rod 604.

[0025] First, when the raw material passes through the splint 605, the cylinder 1 601 can be controlled to move. At this time, the cylinder 1 601 will push one of the push rods 604. At the same time, the push rod 604 will drive the top push plate to move synchronously through the connecting rod 603 and the rotating plate 602, so that the push rods 604 are close to each other, and the splints 605 will also move accordingly, so that the splints 605 on both sides will return the raw material to the middle position of the roller 3, thereby preventing the data detected by the detector 4 from being wrong due to the angle problem of the raw material, reducing the error of the detection data, thereby reducing the difficulty of operation for personnel, and better improving the accuracy of the detection data.

[0026] like Figure 4 As shown, the ejection mechanism 7 includes a top plate 701, a second cylinder 702, a positioning rod 703, a spring 704 and a fixed plate 705.

When the cylinder 2 702 extends, the top plate 701 will be pushed out from the gap between the rollers 3, so that the raw materials roll to the inside of the discharge plate 8 and are collected by the external collection box. The external device controls one of the two cylinders 2 702 to classify raw materials of different lengths. The raw materials can be quickly classified through the ejection mechanism 7, thereby reducing the inconvenience caused by personnel classification.

[0028] Here’s how it works:

[0029] When in use, first, when the raw material passes through the splint 605, the cylinder 1 601 can be controlled to move. At this time, the cylinder 1 601 will push one of the push rods 604, and at the same time, the push rod 604 will drive the other push plate to move synchronously through the connecting rod 603 and the rotating plate 602, so that the push rods 604 are close to each other, and the splints 605 will also move accordingly, so that the splints 605 on both sides will return the raw material to the middle position of the roller 3, thereby preventing the data detected by the detector 4 from being wrong due to the angle problem of the raw material. The corrected raw material will pass through the detector 4, which uses the intelligent laser triangulation displacement sensor optoNCDT1420. The detector 4 uses a laser to detect the length of the raw material, and then transmits the detected data to the external device, and then the external device controls the cylinder 2 702 on both sides to move. When the cylinder 2 702 extends, the top plate 701 will be pushed out from the gap between the rollers 3, so that the raw material rolls to the inside of the discharge plate 8 and is then collected by the external collection box.
