[0022] At the same time, a plate-shaped connecting plate 4 and a box-shaped glue spraying chamber 5 are fixedly connected between the two driving rollers 3 on the side surfaces of the two supporting plates 1, and the glue spraying chamber 5 is located below the connecting plate 4, and a rectangular cavity-shaped glue storage chamber 6 is fixedly connected to the upper surface of the connecting plate 4, and two tubular glue spraying nozzles 7 are fixedly connected to the lower surface of the glue storage chamber 6, and the two glue spraying nozzles 7 penetrate the connecting plate 4 and the glue spraying chamber 5 to the inside of the glue spraying chamber 5, and a control valve is fixedly connected to the outer surface of the glue spraying nozzle 7, so that the opening of the glue spraying nozzle 7 can be controlled by the control valve, so that the glue in the glue storage chamber 6 can be sprayed downward through the glue spraying nozzle 7 The surface of the bandage facing downwards, and two rod-shaped connecting rods 9 are slidably connected to the side surface of the glue spraying bin 5, the ends of the two connecting rods 9 that are far away from each other penetrate the support plate 1 to the outside thereof, and the ends of the two connecting rods 9 that are close to each other penetrate the glue spraying bin 5 to the inside thereof, and are fixedly connected with a plate-shaped baffle 8, and the two baffles 8 slide relative to the inner wall of the glue spraying bin 5, so that by controlling the sliding of the two connecting rods 9, the spacing between the two baffles 8 can be changed, so that the width of the glue spraying can be controlled according to the width of different bandages, so that it is suitable for uniformly spraying glue on bandages of different widths, thereby improving the versatility and practicality of the device;

[0023] Secondly, a rod-shaped brush rod 11 is fixedly connected to the side surface of the two support plates 1 at the side of the glue spraying bin 5, so that before spraying glue, the upper surface of the bandage can be cleaned by the brush rod 11 to prevent dust from affecting the glue spraying quality of the bandage and improve the adhesion. A frame-shaped mounting plate 12 is fixedly connected to the side surface of the two support plates 1 at the side of the glue spraying bin 5 away from the brush rod 11, and a plurality of fans 13 are rotatably connected to the lower surface of the mounting plate 12, so that after the glue spraying is completed, the glue on the surface of the bandage can be dried by the rotation of the plurality of fans 13, thereby improving production efficiency.
