A plurality of nozzles 10 are evenly connected on the circumference of the upper part of the water pipe 8, and a heating cylinder 11 is sleeved on the outer side of the upper part of the water pipe 8. The bottom of the heating cylinder 11 is open and fixedly provided with a flange 12. The bottom of the flange 12 is detachably connected to the bottom plate 6. The flange 12 and the cylinder wall of the heating cylinder 11 are both hollow, and a plurality of evenly distributed electric heating plates 13 are fixedly arranged in the flange 12, and an electric heating wire 14 is wound in the cylinder wall of the heating cylinder 11. A first motor 15 is fixedly mounted on the horizontal part of the bracket 5, and the output shaft of the first motor 15 faces downward and is fixedly connected to a hot melt barrel 16. The top of the hot melt barrel 16 is connected to a feed pipe 18 with a feed valve 17, and the lower part of one side is connected to a discharge pipe 20 with a discharge valve 19. The bottom is open and can be plugged and rotatably arranged on the slide 7. A plurality of groups of second motors 21 are fixedly mounted on the outer wall of the hot melt barrel 16 at intervals up and down, and each group of second motors 21 has a plurality of motors 21 distributed at intervals in a circle.
