[0002] Hot melt adhesive (English name: Hot Glue) is a plastic adhesive.

In addition, the rotating shaft 14 is sequentially provided with a rounding roller 16, an extrusion plate 17, a mechanism spring 18, a second gear 19, and a control box 20. A third gear 21 is meshed between the wheels 19, a control mechanism is arranged in the control box 20, and the control mechanism includes a mechanism ring 46, a plurality of uniformly distributed control blades 47 are arranged on the outer ring surface of the mechanism ring 46, a plurality of limit card plates 48 are arranged on the inner ring surface of the mechanism ring 46, the mechanism ring 46 is sleeved on the rotating shaft 14, and a limit card groove 141 which is slidably connected with the limit card plate 48 is opened on the rotating shaft 14, a pipe mouth 22 is arranged near the top of one side of the control box 20 and near the bottom of the other side, a liquid inlet pipe 23 and a liquid outlet pipe 24 are arranged at one end of the water bag 13, a hose 25 is connected between the liquid outlet pipe 24 and the pipe mouth 22, and the rotating shaft 14 is rotated by the cooperation of the control mechanism, the water bag 13 and the hose 25, and the liquid inlet pipe 2 3 and the liquid outlet pipe 24 are both provided with a flow-stop assembly, the flow-stop assembly in the liquid outlet pipe 24 is used to prevent the water entering the hose 25 from flowing back into the water bag 13, and the flow-stop assembly in the liquid inlet pipe 23 is used to prevent the water entering the water bag 13 from flowing back into the device box 1, the flow-stop assembly includes two flow-stop plates 49, each of which is provided with a flow-through hole, a compression spring 50 and a baffle ball 51 are provided between the two flow-stop plates 49, a T-shaped liquid-through hole 511 is provided on the baffle ball 51, the diameter of the baffle ball 51 is larger than the diameter of the flow-through hole, and the diameter of the baffle ball 51 is smaller than the inner diameter of the liquid inlet pipe 23 and the liquid outlet pipe 24, when water is injected into the device box 1 through the high-pressure water pump 2, the water flow entering the drive box 3 will impact the drive mechanism in the drive box 3, causing it to work , the rotating disk 38 is driven to rotate through the connecting shaft 37, so as to cooperate with the connecting rod mechanism to move the control plate 5. In the process of moving the control plate 5, the moving rod 12 of the hot melt adhesive rounding mechanism is driven to move through the cooperation of the latch 6 and the first gear 15, so as to push the rotating shaft 14 and the rounding roller 16 to move.

In this way, in the process of moving the control plate 5, the two rounding rollers 16 of each group of hot melt adhesive rounding mechanisms can always move in opposite directions. As the rotating shaft 14 moves, the extrusion plate 17 compresses the mechanism spring 18, and the rotating shaft 14 compresses the water bag 13.The water in the water bag 13 enters the control box 20 through the hose 25, impacts the control blade 47 of the control mechanism in the control box 20, rotates the mechanism ring 46 and the limit card plate 48, thereby driving the rotating shaft 14 to rotate, and through the meshing cooperation of the two second gears 19 and the third gear 21, the two full-circle rollers 16 rotate in the same direction. As the control plate 5 moves back and forth repeatedly, under the cooperation of the wavy structural surface, the mechanism spring 18 will also continuously push the extrusion plate 17 to reset the rotating shaft 14, and then Under the action of the pulling force, the water bag 13 recovers and the water is pumped into the water bag 13 through the liquid inlet pipe 23. Through the above process, as the water flow increasing mechanism drives the water to flow downward faster, the hot melt rubber particles after cutting will fall between the two full-circle rollers 16 under the action of the dragging force of the downward flowing water. As the two full-circle rollers 16 continue to rotate and move, the hot melt rubber particles are rounded, and then the spherical hot melt rubber particles will fall from the gap between the two full-circle rollers 16 along with the water, and be discharged through the discharge channel 4 at the bottom of the device box 1;
