As shown in fig. 5 and 6, the glue spreading mechanism 3 includes a spraying block 31, a plurality of venturi tubes 32 are uniformly arranged in the spraying block 31, an air inlet of each venturi tube 32 is connected with an air inlet tube 33, a throat of each venturi tube 32 is communicated with the glue spreading mechanism 3 through a glue inlet tube 34, and a glue inlet electromagnetic valve (a return electromagnetic valve, a recovery electromagnetic valve and a glue inlet electromagnetic valve are of conventional electromagnetic valve structures and are not shown in the drawings) is arranged on the glue inlet tube 34. The glue coating block is internally provided with the venturi tube 32, after the high-pressure air flow is introduced into the air inlet tube 33, the high-pressure air flow generates stronger negative pressure at the throat of the venturi tube 32, the glue solution is sucked into the venturi tube 32 and is quickly mixed with the air flow to form a gas-liquid mixture, and then the gas-liquid mixture is discharged from the discharge end, so that the glue solution can form tiny glue drops by utilizing the venturi structure, and the spraying uniformity of the glue solution is ensured.
As shown in fig. 6, the discharge end of the venturi tube 32 is connected with a spray head 35 in a threaded manner, and the venturi tube 32 is connected with the spray head 35 in a threaded manner, so that different spray heads 35 can be replaced according to different gluing requirements.
