A stirring assembly is installed on the top surface of the tank body 1, and a circulation assembly 8 is provided on the outside of the tank body 1. The circulation assembly 8 includes a mounting frame 9, which is located on the outside of the tank body 1. A melt pump 10 is installed on the top surface of the mounting frame 9. An input pipe 11 is installed on one side of the melt pump 10, and an output pipe 12 is installed on the top surface of the melt pump 10. A heat insulation layer 13 is provided on the outer surface of the input pipe 11 and the output pipe 12. The inner wall of the heat insulation layer 13 and the outer walls of the input pipe 11 and the output pipe 12 form a heat insulation cavity 14. A diversion pipe 15 is provided on the outside of the heat insulation layer 13, and an outlet pipe 16 is provided on the outside of the output pipe 12. A ball valve 17 is provided on the outside of the output pipe 12 and the outlet pipe 16. A circulation pipe 18 is installed on the top surface of the output pipe 12.
[0023] The stirring assembly includes a drive motor 2, a stirring blade 3 installed at the bottom of the drive motor 2, a heating tank 4 installed on the outside of the tank body 1, the inner wall of the heating tank 4 and the outer wall of the tank body 1 forming a heating chamber 5, a heating inlet pipe 6 installed on the inner wall of the heating tank 4, and a glue outlet pipe 7 installed on the bottom surface of the tank body 1.
[0024] The inner walls of the input pipe 11 and the output pipe 12 are interconnected by the melt pump 10. The two ends of the insulation layer 13 are fixedly connected to the outer surfaces of the output pipe 12 and the input pipe 11. The inner wall of the diversion pipe 15 is interconnected with the insulation cavity 14.
[0025] The drive motor 2 is started, causing the stirring blades 3 to rotate and initially mix the hot melt adhesive. Simultaneously, a heat source, such as steam or hot water, is injected into the heating chamber 5 through the heating inlet pipe 6. The heat in the heating chamber 5 is evenly distributed through the distribution pipe 15, heating the hot melt adhesive in the tank 1. During the heating process, the melt pump 10 of the circulation component 8 starts working, drawing the hot melt adhesive from the tank 1 into the tank 1 through the inlet pipe 11 and then returning it to the tank 1 through the outlet pipe 12, forming a circulating heating process. Example 2
[0026] Based on the above embodiment 1, please refer to Figures 3-5 The inner wall of the outflow pipe 16 is connected to the inner wall of the output pipe 12. The outflow pipe 16 is located below the diversion pipe 15. The ball valve 17 controls the opening and closing of the output pipe 12 and the outflow pipe 16. The inner wall of the circulation pipe 18 is connected to the inner wall of the output pipe 12.
[0027] The bottom end of the drive motor 2 is fixedly connected to the top surface of the tank 1, the output end of the drive motor 2 is fixedly connected to the top surface of the stirring blade 3, and the outer surface of the stirring blade 3 is movably and rotatably connected to the inner wall of the tank 1.
[0028] The inner wall of the heating inlet pipe 6 is in communication with the inner wall of the heating chamber 5, and the inner wall of the heating chamber 5 is in communication with the diversion pipe 15. The diversion pipe 15 is used to divert the heat source in the heating chamber 5.
[0029] The diversion pipe 15 has one connecting end and two input ends. The two input ends of the diversion pipe 15 are connected to the insulation cavities 14 that are in contact with each other. The connecting end of the diversion pipe 15 is connected to the inner wall of the heating chamber 5.
[0030] The insulation layer 13 maintains the temperature of the hot melt adhesive in the input pipe 11 and output pipe 12, reducing heat loss. Meanwhile, the circulation pipe 18 allows the hot melt adhesive to continue circulating within the output pipe 12, further improving heating efficiency and uniformity. Once the hot melt adhesive reaches the required temperature and uniformity, the ball valve 17 installed on the outflow pipe 16 is opened, and the ball valve 17 on the output pipe 12 is closed, allowing the hot melt adhesive to flow out through the outflow pipe 16.
[0031] The working principle and usage process of this utility model are as follows: the hot melt adhesive raw material to be prepared is added into the tank 1, and the drive motor 2 is started to make the stirring blade 3 start to rotate, so as to initially mix the hot melt adhesive.
[0032] Simultaneously, a heat source, such as steam or hot water, is injected into the heating chamber 5 through the heating inlet pipe 6. The heat in the heating chamber 5 is evenly distributed through the distribution pipe 15, heating the hot melt adhesive in the tank 1. During the heating process, the melt pump 10 of the circulation component 8 starts working, drawing the hot melt adhesive from the tank 1 through the inlet pipe 11 and then sending it back into the tank 1 through the outlet pipe 12, forming a circulating heating process to ensure that the hot melt adhesive is heated evenly.
[0033] The insulation layer 13 maintains the temperature of the hot melt adhesive in the input pipe 11 and output pipe 12, reducing heat loss. Meanwhile, the circulation pipe 18 allows the hot melt adhesive to continue circulating within the output pipe 12, further improving heating efficiency and uniformity.
[0034] Once the hot melt adhesive reaches the required temperature and uniformity, open the ball valve 17 installed on the outflow pipe 16 and close the ball valve 17 on the output pipe 12. The hot melt adhesive will then flow out through the outflow pipe 16 for subsequent use or processing.
