[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment: a new hot melt welding machine, including an operating table 1, the top of the operating table 1 is rotatably connected with a connecting column 7, the top of the connecting column 7 is fixedly connected with a cam 6, the outer wall of the connecting column 7 is fixedly connected with a rotating rod 5, the top of the operating table 1 is slidably connected with a first movable plate 8, the side wall of the cam 6 is in contact with the first movable plate 8, a second movable plate 13 is arranged on one side of the first movable plate 8, both ends of the first movable plate 8 and the second movable plate 13 are slidably connected with a connecting rod 14, the outer wall of the connecting rod 14 is arranged with a reset spring 15, the two ends of the reset spring 15 are located at the opposite sides of the first movable plate 8 and the second movable plate 13, and the tops of the first movable plate 8 and the second movable plate 13 are arranged with a clamping mechanism.

[0025] Specifically, when hot-melt welding is performed on the pipeline, the pipeline is fixed by a clamping mechanism, and the cam 6 is rotated by rotating the rotating rod 5. The rotation of the cam 6 will push the first movable plate 8 to move back and forth. At the same time, the second movable plate 13 will move synchronously due to the action of the connecting rod 14 and the return spring 15, so that the distance between the first movable plate 8 and the second movable plate 13 changes, so that the pipeline to be welded moves synchronously, which can improve the movement synchronization of the pipeline to be welded during welding and improve the welding efficiency.

[0026] Reference Figure 3The clamping mechanism includes an upper clamping block 9, which is installed on the top of the first movable plate 8 and the second movable plate 13.
