[0017] like Figure 1-6 As shown in the figure, this application proposes a feeding device for a pipe cutting machine, including a frame 1, multiple conveyor frames 2, a feeding drive device 3, multiple linkage devices 4, and multiple translation drive devices 5.

The two ends of each translation drive device 5 are respectively connected to two adjacent conveyor frames 2. The feeding drive device 3 is disposed on any one of the conveyor frames 2 and is connected to any one of the linkage devices 4.

[0018] This utility model discloses a feeding device for a pipe cutting machine, comprising a frame 1, multiple conveyor frames 2, a feeding drive device 3, multiple linkage devices 4, and multiple translation drive devices 5. The frame 1 provides support and is driven by the feeding drive device 3. The multiple linkage devices 4 and multiple conveyor frames 2 are connected to achieve linkage, so as to transmit power to each conveyor frame 2. The outermost conveyor frame 2 is fixedly connected to the frame 1. This conveyor frame 2 is connected to the adjacent conveyor frame 2 through any of the translation drive devices 5. The other conveyor frames 4... The conveying frames 2 are sequentially connected via the translation drive device 5, allowing for flexible adjustment of the distance between adjacent conveying frames 2. In this application, a feeding device for a pipe cutting machine is disclosed, where the outermost conveying frame 2 is fixedly connected to the frame 1 to provide structural support. The distance between adjacent conveying frames 2 can be adjusted via the translation drive device 5, adapting to pipes of different lengths and improving the versatility of the feeding device. Furthermore, the cooperation of multiple linkage devices 4 and multiple conveying frames 2 ensures synchronous operation of each conveying frame 2, achieving stable pipe transport.

[0019] Each of the conveyor frames 2 includes a frame body 21, a first sprocket 22, a second sprocket 23, and a conveyor chain 24. The first sprocket 22 and the second sprocket 23 are rotatably disposed on the inner sides of both ends of the frame body 21. The conveyor chain 24 is sleeved on the first sprocket 22 and the second sprocket 23. Each of the linkage devices 4 includes a first universal joint coupling 41, a second universal joint coupling 42, and a telescopic shaft 43.

The feeding drive device 3 drives any of the linkage devices 4 to rotate, and the linkage device 4 drives the adjacent first sprockets 22 to rotate. The conveying chain 24 on it moves and drives the second sprocket 23 to rotate synchronously, so as to realize the conveying of the pipe.

Through the cooperation of the anti-rotation strip 435 and the slot 436, on the one hand, it guides the sliding between the telescopic rod 434 and the sleeve 433, and the anti-rotation strip 435 further reinforces the sleeve 433; on the other hand, it restricts the relative rotation between the telescopic rod 434 and the sleeve 433, ensuring the synchronous rotation of the first rod body 431 and the second rod body 432, and ensuring that the linkage device 4 continuously and stably transmits power; in addition, the limiting block 438 is inserted into the clearance groove 437 to prevent the telescopic rod 434 from disengaging from the sleeve 433.

[0021] The feeding drive device 3 includes a bracket 31, a drive motor 32, a third sprocket 33, a connecting rod 34, a fourth sprocket 35, and a transmission chain 36. The bracket 31 is mounted on any of the frame bodies 21. The drive motor 32 is fixed to the bracket 31. The third sprocket 33 is connected to the output end of the drive motor 32.

The multiple guide rods 13 and the multiple vertical frames 212 correspond one-to-one and slide in cooperation. During the movement of each conveyor frame 2, the cooperation of the vertical frames 212 and the guide rods 13 restricts the movement direction of the conveyor frame 2, ensuring that the conveyor frame 2 moves in a straight line, while further supporting the conveyor frame 2 and improving the stability of pipe conveying.

[0023] Each of the translation drive devices 5 includes a concave frame 51, a pulley seat 52, a lead screw 53, a slider 54, a motor 55, a drive gear 56, and a driven gear 57.

One end of the concave frame 51 is fixedly connected to any of the conveyor frames 2, and the other end of the concave frame 51 is suspended below the adjacent conveyor frame 2. The slider 54 is fixed to the bottom of the adjacent conveyor frame 2. The two ends of the lead screw 53 are rotatably connected to both sides inside the concave frame 51. The lead screw 53 passes through the slider 54 and is threadedly connected to the slider 54. The motor 55 is located on the concave frame 51. The drive gear 56 is connected to the output end of the motor 55. The driven gear 57 is located on the lead screw 53, and the drive gear 56 meshes with the driven gear 57. The motor 55 drives the drive gear 56 to rotate, and the drive gear 56 meshes with the driven gear 57 to drive the driven gear 57 to rotate. The rotation of the driven gear 57 drives the synchronous rotation of the lead screw 53. The lead screw 53 and the slider 54 are threadedly connected, thereby converting the rotation of the lead screw 53 into the linear motion of the slider 54, thereby driving the adjacent conveyor frame 2 to translate. The concave frame 51 moves with any of the conveyor frames 2. The translation drive device 5 only adjusts the distance between two adjacent conveyor frames 2. The subsequent multiple conveyor frames 2 can move synchronously with the previous conveyor frame 2. Each stage can be adjusted independently, which improves the flexibility of the feeding equipment. The pulley seat 52 provides stable support for the concave frame 51. At the same time, the translation drive device 5 also stably supports the two conveyor frames 2 on it, further improving the stability of each conveyor frame 2 during operation.

[0024] The feeding equipment also includes a sensing device 6, which is located on the discharge end of any of the conveying frames 2. The sensing device 6 is electrically connected to the feeding drive device 3. The sensing device 6 includes a contact plate 61, a sensor 62, and a reset assembly 63. The sensor 62 is located on any of the conveying frames 2. The contact plate 61 is connected to the sensor 62 through the reset assembly 63. The sensor 62 includes a limit switch. The reset assembly 63 adopts a common spring reset mechanism or torsion spring reset mechanism. The pipe presses the contact plate 61 to rotate, triggering the sensor 62 and controlling the start and stop of the feeding drive device 3 to ensure that the pipe is conveyed to the set position and to ensure the accuracy of the pipe conveying.
