[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following structure, the description of the well-known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] like Figure 1-2The laboratory improved hot melt adhesive preheater shown includes a preheating box body 100, and the interior of the preheating box body 100 is provided with at least one preheating cavity 110, and in this embodiment, there are two.

[0026] The preheating box body 100 is a detachable plate structure, and the detachable plate structure is a detachable plate structure assembled by embedded fixing bolts.

[0027] A single preheating chamber 110 is provided with a preheating tube 120, and the upper end of the preheating tube 120 extends out of the upper end of the preheating chamber 110. This makes it easier to add materials.

[0028] The preheating tube 120 is a hollow design with an opening at the upper end, and a heating kit 130 is provided at the preheating cavity 110 near the lower end of the preheating tube 120. The heating kit 130 is a heating ring. A heat insulation structure layer 150 is provided around the upper end protrusion of the preheating tube 120. The heat insulation structure layer 150 is made of high temperature resistant silicone material.

[0029] The heating kit 130 is connected to the temperature controller 140 through a line. The signal receiving component 141 of the temperature controller 140 is set on the upper surface of the preheating box body 100. The signal receiving component 141 receives the signal and transmits it to the temperature controller 140. The temperature of the heating kit 130 is controlled by the temperature controller 140. A protective cover 142 is set outside the temperature controller 140.

[0030] A handle 101 is provided on the side of the preheating box body 100 .

[0031] Because of the above structure, the working principle of the utility model is:

[0032] The preheating box of the utility model preheats the hot melt adhesive in the hot melt adhesive preheater before using the hot melt adhesive in the dispensing equipment. Through precise temperature control, the preheated molten glue can be directly tested and used, saving waiting time and improving production efficiency. At least one signal receiving component 141, i.e., a thermostat panel, is provided on the top of the box body for displaying the temperature of the thermostat, and a switch button is also provided next to the thermostat panel to independently control the two preheating tubes 120, further expanding the scope of use and having the advantages of high efficiency, speed and energy saving.
