When in use, the one-way screw 403 is driven by the lifting motor 401 to drive the one-way screw 40 3 is rotated to make the lifting block 404 descend, thereby driving the barrel cover 405 and the two-way stirring structure 6 to slowly descend to the inside of the stirring barrel 3, and the raw materials of the water-based adhesive in the stirring barrel 3 are stirred and mixed by the two-way stirring structure 6. After the processing is completed, the lifting motor 401 drives the one-way screw 403 to rotate in the opposite direction to make the lifting block 404 rise, so that the barrel cover 405 and the two-way stirring structure 6 slowly rise to be away from the stirring barrel 3, and the stirring process is completed. On the one hand, it is convenient to push the material out of the stirring barrel 3, and on the other hand, it is convenient to clean the first stirring blade 605 and the second stirring blade 610 of the two-way stirring structure 6.

The movable rod 509 is rotatably connected to the inner side of the fixed block 508. After the water-based adhesive raw material is loaded into the mixing barrel 3, the lifting motor 401 is controlled to drive the one-way screw 403 to rotate, so that the lifting block 404 threadedly connected to the surface of the one-way screw 403 slowly slides downward, so that the two-way stirring structure 6 enters the mixing barrel 3 from top to bottom to mix and stir the raw materials. At the same time, the surface of the one-way screw 403 is fixedly connected to the first bevel gear 504 and rotates, and the driven bevel gear 506 is driven to rotate through the transmission bevel gear 505, so that the cross column The bidirectional screw 503 in 501 rotates, causing the two sliding blocks 507 threadedly connected on both sides of the surface of the bidirectional screw 503 to slide synchronously and slowly toward both sides, driving one end of the first transmission rod 509 to move outward, causing the other end of the first transmission rod 509 to rotate slowly inward until the bidirectional stirring structure 6 completely enters the interior of the stirring barrel 3, and finally causing the clamping block 510 to cling to the outer surface of the stirring barrel 3, clamping the stirring barrel 3, thereby achieving precise stirring and stable fixation of the raw materials inside the stirring barrel 3, and improving stirring efficiency and safety.

[0040] Example 4: Reference Figure 1 , 5 and 6, a discharging structure 7 installed on both sides of the column 2, which is used to push the mixing barrel 3 outward to realize automatic discharging after the mixing process is completed;

[0041] The discharging structure 7 includes a rack 701, a spur gear 702, a pressing structure 704 and a push rod structure 706. The rack 701 is fixedly connected to the side surface of the lifting block 404. The spur gear 702 is rotatably connected to the upper part of the two side surfaces of the column 2. The side surface of the spur gear 702 is rotatably connected to the rotating rod 703. The pressing structure 704 includes a second transmission rod 7041 and a roller 7042. The upper part of the second transmission rod 7041 is rotatably connected to the lower end of the rotating rod 703. The roller 7042 is rotatably connected to the lower end of the second transmission rod 7041. The push rod structure 706 The push rod body 7062 and the inclined block 7061 are fixedly connected to one end of the push rod body 7062. Two groups of the pressing structure 704 and the push rod structure 706 are arranged on one side of the column 2. The two groups of the pressing structure 704 are connected to each other through the U-shaped rod 705. The two groups of the push rod structures 706 are connected to each other through the connecting rod 708. The two side surfaces of the column 2 are fixedly connected with the slide rail 707. The upper group of the push rod structure 706 is slidably connected to the inner side of the slide rail 707. The upper surface of the horizontal column 501 and the upper surface of the base 1 are A stopper 7064 is fixedly connected, and a spring structure 7063 is provided between the stopper 7064 and each group of push rod structures 706. After the stirring process is completed, the two-way stirring structure 6 slides upward to reset. When the lifting block 404 slides to a position close to the spur gear 702, the rack 701 and the spur gear 702 on the surface of the lifting block 404 mesh with each other, so that the spur gears 702 on both sides rotate, and the spur gears 702 drive the rotating rod 703 to rotate downward, squeezing the second transmission rod 7041 and the roller 7042 downward, and the roller 7042 is rotated on the inclined block 7061. The inclined surface rolls downward, causing the inclined block 7061 to slide toward one side, and the mixing barrel 3 is pushed outward through the push rod body 7062 to realize discharging, thereby realizing the automatic pushing out of the mixing barrel 3 after the mixing is completed, simplifying the discharging process, and improving production efficiency and operational convenience. At the same time, the upper and lower groups of pressing structures 704 are connected by the U-shaped rod 705, and the upper and lower groups of push rod structures 706 are connected by the connecting rod 708, so as to realize synchronous pushing outward from the upper and lower surfaces of the mixing barrel 3, ensuring the overall stability of the mixing barrel 3 when being pushed out, and improving the accuracy and safety of the operation.

[0042] When in use, the water-based adhesive raw materials to be prepared are prepared and loaded into the mixing barrel 3, and the lifting motor 401 is started. The lifting motor 401 drives the one-way screw 403 to rotate, and the lifting block 404 threadedly connected to the surface of the screw slowly slides downward in the lifting groove 402. As the lifting block 404 descends, the barrel cover 405 fixed on one side of the lifting block 404 and the two-way stirring structure 6, including the first stirring blade 605 and the second stirring blade 610, are lowered into the mixing barrel 3 together. When the stirring structure descends, the first bevel gear 504 is driven by the transmission bevel gear 505 and the driven bevel gear 506. The gear 506 drives the bidirectional screw 503 to rotate, and the sliding block 507 on the surface of the bidirectional screw 503 slides to both sides synchronously, and the clamping block 510 is pressed against the outer side of the mixing barrel 3 through the first transmission rod 509 to achieve stable fixation of the mixing barrel 3.

After the stirring reaches the predetermined time or effect, the driving motor 601 is stopped to end the stirring process, and the lifting motor 401 is started in the reverse direction to make the one-way screw 403 rotate in the reverse direction. The lifting block 404 starts to rise, driving the barrel cover 405 and the two-way stirring structure 6 to slowly rise to a position away from the stirring barrel 3. At the same time, the clamping structures 5 on both sides relax the clamping of the stirring barrel 3. When the lifting block 404 rises to a position close to the spur gear 702, the rack 701 on the surface of the lifting block 404 meshes with the spur gear 702, and the spur gear 702 The push rod 706 is pressed downward by the second transmission rod 7041 and the roller 7042, and the inclined block 7061 of the push rod structure 706 converts the downward pressing force into a force that causes the push rod to slide toward the front end, so that the push rod body 7062 slides toward the front end and pushes the mixing barrel 3 forward. At the same time, the upper and lower groups of West Asia structures and the push rod structure 706 are connected by the U-shaped rod 705 and the connecting rod 708 to move synchronously. The mixing barrel 3 is pushed forward synchronously by the upper and lower groups of push rod structures 706, so that the mixing barrel 3 is more stable during the pushing process, and automatic discharging is achieved.
