The inner cavity of the defoaming box located just below the push block is connected to a discharge pipe. Solvent-free glue is added through the glue supply box, and then the lifting cylinder drives the pressing plate to move up and down, forming a negative pressure to suck the glue in the glue supply box, and then the pressing plate is pressed downward to transport it to the inside of the sealed transfer mechanism below. The one-way valve can be set to discharge the air squeezed to the top of the glue under pressure to perform the first step of separation. The screen can be set to screen the glue while the internal The bubbles are punctured to float to the surface of the solvent-free glue, and the solvent-free glue is transported to the sealing transfer mechanism.

A drainage block 17 fixedly connected to the right side of the elastic sealing belt 15 is fixedly connected to the right side of the defoaming box 1. A slope surface gradually rising from left to right is arranged on the left side of the drainage block 17. The drainage block 17 separates the defoaming box 1 from the discharge trough 22. The inner cavity of the drainage block 17 is provided with a guide groove 18 connected to the inner cavity of the defoaming box 1 and the discharge trough 22. The inner cavity of the drainage block 17 is connected to the inner cavity of the defoaming box 1 and the discharge trough 22. A push block 21 driven by a cylinder is slidably connected, and the inner cavity of the defoaming box 1 located directly below the push block 21 is connected to a discharge pipe 23. Solvent-free glue is added through the glue supply box 2, and then the lifting cylinder 5 drives the pressing plate 6 to move up and down, forming a negative pressure to suck the glue in the glue supply box 2, and then the pressing plate 6 is pressed downward to transport it to the inside of the sealed transfer mechanism below, and the one-way valve 8 is set to discharge the air squeezed to the top of the glue under pressure to perform the first step of separation. The screen 10 is set to screen the glue while the inner The bubbles in the bottom are punctured to float to the solvent-free surface, and the solvent-free glue is transported to the sealed transfer mechanism. The solvent-free glue squeezed and compacted by the pressing plate 6 enters the placement groove 13, and then the rotating cylinder 12 rotates to drive the placement groove 13 filled with the solvent-free glue to rotate downward. Under the action of gravity, the solvent-free glue is transported to the debubble box 1. The operation is repeated and the transfer is continuously carried out. During the transfer, the debubble box 1 and the conveying box 3 are kept sealed continuously, which can effectively prevent the outside air from entering the debubble box 1.

The inner cavity of the rotating cylinder 12 is provided with two symmetrical placement grooves 13 in an upper and lower direction. The rotating cylinder 12 is driven to rotate by a motor, and the solvent-free glue squeezed and compacted by the pressing plate 6 enters the placement groove 13. Then the rotating cylinder 12 rotates to drive the placement groove 13 filled with the solvent-free glue to rotate downward. Under the action of gravity, the solvent-free glue is transported to the defoaming box 1. The operation is repeated for continuous transfer. During the transfer, the defoaming box 1 and the conveying box 3 are kept continuously sealed, which can effectively prevent external air from entering the defoaming box 1.

[0023] The top of the debubble box 1 is connected to an exhaust hopper 20 connected to an external vacuum pump.
