[0013] The utility model will be described in further detail below in combination with the drawings.
[0014] As shown in FIGS. Figure 1 , 2 , 3, the glue tank structure of the halogen-free epoxy glass cloth paper substrate in the embodiment includes an inner glue tank body 5 and an outer glue tank body 4. The inner glue tank body 5 is arranged in the outer glue tank body 4 and penetrates the outer glue tank body 4 at the bottom of the inner glue tank body 5. The two are fixedly connected. There is a gap between the inner wall of the outer glue tank body 4 and the outer wall of the inner glue tank body 5, forming an overflow cavity. A glue feeding groove is formed at the center of the bottom of the inner glue tank body 5. Two spaced glue feeding ports 6 are arranged in the glue feeding groove. The two glue feeding ports 6 are respectively connected to glue feeding pipes 2. The two glue feeding pipes 2 are in communication with a glue tank. The height of the side plates around the outer glue tank body 4 is higher than the height of the side plates around the inner glue tank body 5. A glue return pipe 1 is connected to the outer glue tank body 4. One end of the glue return pipe 1 is in communication with the overflow cavity, and the other end of the glue return pipe 1 is connected to the glue tank. The glue in the glue tank flows into the inner cavity of the inner glue tank body 5 through the glue feeding pipe 2. When the liquid level of the glue reaches a certain position, the glue with bubbles on the surface flows into the overflow cavity through the overflow port. The glue in the overflow cavity flows back to the glue tank through the glue return pipe. The glue tank stirs the backflowing glue to eliminate the bubbles on the surface of the glue and recycle the glue, avoiding bubbles sticking to the surface of the glue paper.
[0015] A cover plate 7 is arranged on the glue feeding groove. A plurality of flow dividing holes 8 are formed in the cover plate 7 to disperse the glue.
