[0030] The stirring assembly 4 comprises a driving motor 401, a rotating shaft 402, a spiral stirring block 403, a slot 404 and a spiral scraper 405.

The rotating shaft 402 is located in the interior of the stirring barrel 1. The spiral stirring block 403 is fixedly connected to the outer wall of the rotating shaft 402. The driving motor 401 drives the rotating shaft 402 to rotate at high speed. The spiral stirring block 403 rotates with it. The special spiral structure of the spiral stirring block 403 produces strong stirring effect on the A and B materials entering the stirring barrel 1, so that the materials continuously tumble and mix in the barrel.

[0033] Working principle: first, A and B materials are stored in the two storage barrels 2 respectively. Under normal conditions, the electric push rod 308 drives the first piston 302 to move backward to the bottom right side of the discharge pipe 201. The second piston 303 is stretched to the bottom left side of the discharge pipe 201 by the spring 307. At this time, the materials in the storage barrels 2 enter the sealing installation cylinder 301 through the discharge pipe 201 and the discharge slot of the arc-shaped baffle 309 under the action of gravity, and are located between the first piston 302 and the second piston 303.

[0034] When the material needs to be fed, the electric push rod 308 pushes the first piston 302 to move leftwards, the arc-shaped baffle 309 moves with the first piston 302, and the discharge slot of the arc-shaped baffle 309 gradually separates from the discharge pipe 201, when the arc-shaped baffle 309 completely cuts off the connection between the discharge pipe 201 and the sealing installation cylinder 301, the material cannot flow back into the discharge pipe 201 due to the pressure. Then, with the continuous movement of the first piston 302, the first piston 302 pushes the material between the first piston 302 and the second piston 303 to move leftwards, while stretching the spring 307, the second piston 303 also moves leftwards under the pushing of the material, when the first baffle 305 contacts the second baffle 306, the second piston 303 also contacts the inner left wall of the sealing installation cylinder 301, at this time, the material is just located at the top of the feeding port 101. Then, the first piston 302 continues to move leftwards, and the material between the first piston 302 and the second piston 303 is completely squeezed into the stirring barrel 1, after the feeding is completed, the electric push rod 308 drives the first piston 302 to move rightwards to the initial position, and the second piston 303 also moves rightwards to the initial position under the action of the spring 307, preparing for the next material taking.

[0035] After the material enters the stirring barrel 1, the driving motor 401 is started, the driving motor 401 drives the rotating shaft 402 to rotate, the rotating shaft 402 drives the spiral stirring block 403 to stir and mix the material, the slot 404 makes the material flow more smoothly during the stirring process, the spiral scraper 405 scrapes the material adhered to the inner wall of the stirring barrel 1, after sufficient stirring, the mixed insulation glue can be discharged from the discharge port 102, during the whole process, the stirring barrel 1 can be vacuumized by the vacuum pump 9 according to the needs, and the pressure environment in the stirring barrel 1 can be adjusted by the pressure gauge 7 and the control valve 8.
