[0026] Embodiment:

[0027] Refer to Figures 1 - 5 , a cooling device for hot melt adhesive production, including a cooling water tank 1. An inlet pipe 103 and an outlet pipe 104 are respectively fixedly arranged at both ends of the cooling water tank 1. Valves are fixedly arranged on both the inlet pipe 103 and the outlet pipe 104. Moreover, a top cover 101 is rotatably arranged on the top of the cooling water tank 1. During use, on the one hand, it can reduce the entry of dust into the cooling water tank 1, and on the other hand, it further includes: multiple groups of die plates 3. The number of die plates 3 is set from two groups to ten groups, preferably six groups. The six groups are distributed along the length direction of the cooling water tank 1.

The number of through holes 301 is set from two groups to twenty groups, preferably eleven groups. During use, the hot melt adhesive is sequentially passed through the through holes 301 in the die plates 3. The die plates 3 can drive the hot melt adhesive to lift and lower in the cooling water tank 1. During the lifting and lowering process, the hot melt adhesive can contact the liquid layers in the cooling water tank 1, realizing uniform cooling and improving the cooling effect; A rotating shaft 2 is rotatably arranged in the cooling water tank 1. Multiple groups of U-shaped parts are fixedly arranged on the rotating shaft 2. The number of U-shaped parts is set from two groups to ten groups, preferably six groups. The U-shaped parts are rotatably connected to the die plates 3 through connecting rods 4. And the opening directions of two adjacent U-shaped parts are opposite. A stirring plate 204 is fixedly arranged on the U-shaped parts. During use, by fixedly arranging U-shaped parts on the rotating shaft 2, the U-shaped parts can drive the die plates 3 to lift and lower through the connecting rods 4, making the hot melt adhesive contact the liquid layers in the cooling water tank 1, realizing uniform cooling and improving the cooling effect. And at this time, the stirring plate 204 can stir the liquid in the cooling water tank 1, avoiding the temperature of each liquid layer in the cooling water tank 1 from being inconsistent, resulting in a poor cooling effect and affecting the use effect.

[0028] Refer to Figure 3, here, the U-shaped part includes a first plate 201 and a second plate 202.
