[0042] Please check again. Figure 1 The fully automatic four-sided overlocking equipment 100 also includes a discharge assembly 80, which includes a discharge frame 81, a discharge belt 82, a discharge power element 83, and a sensor (not shown). The discharge frame 81 is installed at one end of the frame 10 near the second overlocking assembly 60. The discharge belt 82 is rotatably connected to the discharge frame 81 and is used to convey the fabric 90. The discharge power element 83 is used to drive the discharge belt 82 to rotate. The sensor is installed on the discharge frame 81 and is used to sense the fabric 90 to measure the length of the fabric 90.

[0043] In use, the material is fed to the first conveyor roller 21 through the cooperation of the feeding roller 73 and the pressing roller 76, and then fed to the first overlock machine 32 through the cooperation of the first conveyor roller 21 and the second conveyor roller 22. The two first overlock machines 32 simultaneously cut and overlock the sides of the fabric 90. After the sides are overlocked, the fabric 90 is conveyed to the discharge belt 82 under the action of the first pulling roller 24 and the second pulling roller 25. When the sensor detects the fabric 90, the conveying of the fabric 90 stops. Next, the second clamping plate 42 moves closer to the first clamping plate 41 to clamp the fabric 90. Then, the slide block 52 drives the cutter 54 to move laterally, thereby cutting the fabric 90 to form two ends. Next, the first clamping plate 41 and the second clamping plate 42 rotate synchronously until the first clamping plate 41 and the second clamping plate 42 are in a horizontal state, with one end of the fabric 90 facing one second overlock machine 62 and the other end of the fabric 90 facing another second overlock machine 62. Then, the second overlock machine 62 slides on the support rod 61 and cuts and overlocks the ends of the fabric 90. The waste material generated from the cutting falls onto the conveyor belt 65 and is then transported to the collection box. Finally, the first clamping plate 41 and the second clamping plate 42 are flipped to a vertical position, and the second clamping plate 42 moves away from the first clamping plate 41, thereby releasing the fabric 90 and continuing to convey the fabric 90, and the operation is repeated; the two sides of the fabric 90 are processed simultaneously by the two first overlock machines 32, and the two second overlock machines 62 process the two ends of the fabric 90 at the same time, which improves efficiency and makes it convenient to use.
