[0023] Specifically, a protective cover 33 is provided on the outside of the vacuum insulation panel 32, and the vacuum insulation panel 32 and the protective cover 33 are connected by a second adhesive layer 36. By adopting the above technical solution, the protective cover 33 is fixed to the outer surface of the vacuum insulation plate 32 through the second adhesive layer 36, which can achieve a good protective effect.

[0024] In this embodiment, the outer surface of the rubber tube 2 is fixed with the heat insulation cotton 31 by the first adhesive layer 35. It works in conjunction with the outer vacuum heat insulation plate 32 to achieve a double heat insulation effect and prevent heat diffusion from burning the staff.

The outer surface of the vacuum heat insulation plate 32 is fixed with the protective cover 33 by the second adhesive layer 36, which can achieve a good protective effect.

[0025] The structure and working principle of the connecting structure 5 (composed of a connecting rod, mounting tube, moving rod, positioning strip, positioning groove, and spring), the heating structure 8 (composed of a heating cylinder and heating wire), and the rotating structure 10 (composed of a servo motor, fixing plate, screw, and cavity) in this utility model have been disclosed in a dispensing device for a concentric screw valve disclosed in Chinese Patent Publication No. CN219024831U. The working principle of the connecting structure 5 is that the connecting rod is inserted into the groove in the mounting tube. During this process, the two sets of moving rods are in an outward pulling state, and the spring is in a compressed state. After both are positioned, the two sets of moving rods are released, and the compressed springs return to their original positions, thus driving the positioning strip to be installed in the positioning groove, achieving a fixed connection between the connecting rod and the installation tube. The working principle of the heating structure 8 is that after the heating wire in the heating cylinder works, it can heat the glue, preventing the glue from being too viscous and clogging the output. The working principle of the rotating structure 10 is that the servo motor works, which can drive the screw to rotate in the cavity. The screw can output the glue delivered by the connecting tube 9 through the needle 4, which can effectively prevent glue clogging and achieve uniform glue dispensing.

[0026] The working principle and usage process of this utility model are as follows: When in use, the fixed cylinder 1 and the glue cylinder 2 are connected via the connecting structure 5. Glue is injected into the glue cylinder 2, and the heating structure 8 heats it. The glue enters the fixed cylinder 1 through the connecting pipe 9. The rotating structure 10 is activated, allowing the concentric screw valve to output the glue through the needle 4, achieving uniform dispensing. The top cover 6 facilitates maintenance of the servo motor. The tip of the unclogging hook 74 is inserted into the needle hole of the needle 4, easily hooking out any solidified glue and preventing blockage. After use, the unclogging hook 74 is placed in the placement structure 72, and then the fixed cover 73 is threaded onto the outer surface of the threaded ring 71 for easy storage of the unclogging hook 74, preventing loss. A placement groove is provided in the placement plate 721. 722 can be used to place the drain hook 74. The concave soft pad 723 has an internal groove that matches the shape of the drain hook 74, which can easily and stably store the drain hook 74 and the soft pad can also provide protection. Rotating the rotating shaft 725 causes the positioning baffle 724 to rotate to the upper end of the drain hook 74, which can limit and block it, and improve the placement stability. The outer surface of the rubber tube 2 is fixed with the heat insulation cotton 31 by the first adhesive layer 35. It works with the outer vacuum heat insulation plate 32 to provide a double heat insulation effect and prevent heat diffusion from burning the staff. The outer surface of the connecting pipe 9 is fixed with the heat insulation felt 34 by the foam adhesive layer 37. The two work together to keep the connecting pipe 9 heat-insulating. The outer surface of the vacuum heat insulation plate 32 is fixed with the protective cover 33 by the second adhesive layer 36, which can provide good protection.
