[0022] Embodiment 1:

[0023] like Figure 1 As shown, the schematic diagram of the structure of the automatic filling device of the raw materials of the glue filling machine provided by the utility model includes a glue tank 1, a vacuum pump 2, a glue suction hose 3, an exhaust valve 4, an air inlet valve 5 and a glue suction valve 6. The glue tank 1 has a glue outlet 101 at the bottom, and a liquid level observation transparent tube 10 is provided on the glue tank 1 to observe the amount of glue inside the glue tank 1. A liquid level height mark 11 is provided on the liquid level observation transparent tube 10, which is convenient for workers to fill glue according to the height mark. A discharge valve 12 is provided at the bottom of the glue tank 1. When brushing the tank to clean the glue, the discharge valve 12 is opened to facilitate the discharge of waste materials.

[0024] The vacuum pump 2 is connected to the top of the glue tank 1 through the exhaust valve 4. The air inlet valve 5 is arranged on the top of the glue tank 1. The air inlet valve 5 is used to control the circulation of external air. When sucking glue, the air inlet valve 5 is closed to form a closed structure inside the glue tank 1 to form a negative pressure space; when filling glue, the air inlet valve 5 is opened to allow external air to flow naturally into the glue tank 1, so that the air pressure inside and outside the glue tank 1 is balanced. A vacuum pressure gauge 7 is also arranged on the top of the glue tank 1 to facilitate checking the pressure value inside the glue tank 1 at any time. It also includes a controller 8 and a signal valve 9. The controller 8 is a relay, and the signal valve 9 is a pneumatic signal valve. The signal valve 9 is connected in series with the exhaust valve 4. Since the signal valve 9 has an automatic control function, the exhaust valve 4 remains normally open during normal use. It is used as an emergency and is enabled when the signal valve 9 fails. The vacuum pressure gauge 7 is an electric contact pressure gauge. The controller 8 is electrically connected to the vacuum pressure gauge 7 and the signal valve 9. When the internal pressure of the glue tank 1 reaches -0.06Mpa, the signal line signal of the electric contact vacuum pressure gauge 7 changes from a low level to a high level, and the signal is transmitted to the relay. The relay controls the gas circuit switch to close the pneumatic signal valve. The controller 8 can also be connected to control the vacuum pump 2. When the signal valve 9 is closed, the vacuum pump 2 automatically cuts off the power supply to achieve the linkage effect of valve closing and pump stopping.

[0025] The glue suction tube 3 is connected to the glue tank 1 through the glue suction valve 6. The glue suction tube 3 is placed in the raw material tank 13. The negative pressure inside the glue tank 1 is used to generate suction to suck the glue in the raw material tank 13 into the glue tank 1. The operation is simple and convenient for workers, and new glue can be added without opening the glue tank 1.

[0026] Working principle:

[0027] When the operator finds that the glue liquid level drops to the lower limit of the liquid level height mark 11, the glue filling pump 14 is closed to stop the glue filling work, and then the air inlet valve 5 and the glue suction valve 6 are closed, and the signal valve 9 is controlled to open, and the vacuum pump 2 is started to discharge the air inside the glue tank 1 to form a negative pressure. When the internal pressure of the glue tank 1 reaches -0.06Mpa, the controller 8 controls the signal valve 9 to close, and the vacuum pump 2 is powered off. At this time, the inside of the glue tank 1 is in a sealed negative pressure state, and then the glue suction tube 3 is placed in the raw material tank 13, and the glue suction valve 6 is opened. The negative pressure inside the glue tank 1 is used to generate suction to suck the glue in the raw material tank 13 into the glue tank 1. When the pressure reaches the standard atmospheric pressure and the external pressure is balanced, the glue suction stops automatically. At this time, the amount of glue in the glue tank 1 accounts for about 80% of the tank body (the amount of glue sucked can be changed by adjusting the negative pressure value according to the actual situation). Then the glue suction valve 6 is closed, and the air inlet valve 5 is opened, and the glue filling pump 14 can be started to continue the glue filling work.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
