As the connecting rod 11 rotates, the connecting rod 11 drives the surface of the T-shaped scraper 15 to scrape the inner cavity of the mixing barrel 7. At this time, the staff starts the cylinder 6 to push the mixing barrel 7 to shake up and down, and at the same time makes the mixing barrel 7 drive the connecting plate 8 to move, so that the surface of the first sliding block 10 slides in the first slide groove 9. Through the setting of the mixing mechanism, it is convenient for the staff to evenly scrape the solder paste stuck to the inner wall of the mixing barrel 7, thereby further improving the stirring efficiency of the device.

The rebound force of the third spring 32 continuously pushes the slide 24 to move to both ends, and at the same time drives the surface of the circular groove 25 to insert into the inner cavity of the circular groove 25, thereby completing the limiting of the box cover 3.

[0034] Working principle: When the staff needs to stir the solder paste evenly, the staff first starts the motor 4, so that the motor 4 drives the rotating rod 5 to rotate, and drives the connecting rod 11 and the stirring blade 12 to rotate at the same time. As the connecting rod 11 rotates, the connecting rod 11 drives the surface of the T-shaped scraper 15 to scrape the inner cavity of the mixing barrel 7. At this time, the staff starts the cylinder 6 to push the mixing barrel 7 to shake up and down, and at the same time, the mixing barrel 7 drives the connecting plate 8 to move, so that the surface of the first slide block 10 slides in the first slide groove 9. Through the setting of the mixing mechanism, it is convenient for the staff to mix the solder paste stuck in the mixing barrel 7. The solder paste on the wall is evenly scraped off, further improving the stirring efficiency of the device. When the staff needs to open the box cover 3, the staff first presses the hollow column 30 to push the slide 24 to move, so that the slide 24 drives the surface of the limit block 26 to gradually separate from the inner diameter of the circular groove 25. At this time, the staff pulls the pull block 28 to drive the connecting block 22 to move, so that the slide 24 and the limit block 26 are separated from the inner cavity of the limit shell 20. At this time, the box cover 3 will not be restrained, and the staff can open the box cover 3, which is convenient for the staff to add solder paste, further improving the use efficiency of the device.
