[0030] A box 5 is fixedly installed on the top surface of the vessel body 1, and a movable plate 6 is longitudinally slidably connected to the inner wall of the right side of the box 5. A stirring rod 7 is installed through the longitudinal bearing on the movable plate 6, and the stirring rod 7 extends into the interior of the vessel body 1. Stirring blades 8 are evenly installed on the surface of the stirring rod 7, and the stirring blades 8 are located inside the vessel body 1.

[0031] A motor 9 is fixedly installed on the inner left side of the housing 5, and a rotating shaft 10 is coaxially fixedly connected to the shaft end of the motor 9. A turntable 11 is fixedly installed on the right side of the rotating shaft 10, and a drive pin 12 is fixedly installed on the right side of the turntable 11. The center line of the horizontal axis of the turntable 11 is collinear with the center line of the horizontal axis of the rotating shaft 10, and the drive pin 12 is located at an eccentric position on the right side of the turntable 11.

[0032] A connecting plate 13 is fixedly installed on the top left end of the movable plate 6, and a horizontally through groove 14 is provided on the connecting plate 13. A drive pin 12 is provided through the groove 14, and the diameter of the drive pin 12 matches the height of the groove 14.

[0033] A sleeve 15 is coaxially fixedly installed at the top of the stirring rod 7, and a twisted rod 16 is threadedly connected inside the sleeve 15, and the twisted rod 16 is fixedly installed on the inner top surface of the box 5.

[0034] A bevel gear set 17 is fixedly installed on the surface of the rotating shaft 10, and the bevel gear set 17 is fixedly connected to the top end of the rotating rod 18. The bottom end of the rotating rod 18 is connected to the top bearing of the vessel body 1, and a drive gear 19 is fixedly installed on the surface of the rotating rod 18. The drive gear 19 meshes with the driven gear 20, and the driven gear 20 is fixedly installed on the surface of the hollow tube 21. The bearing of the hollow tube 21 passes through the top center of the vessel body 1, and the stirring rod 7 is movably installed through the hollow tube 21. A straight rod 22 is fixedly installed at the lower end of the outer wall of the hollow tube 21, and two straight rods 22 are symmetrically arranged. A scraper 23 is fixedly installed at the outer end of the straight rod 22, and the scraper 23 movably abuts against the inner wall of the vessel body 1.

[0035] Working principle: When in use, the polyurethane adhesive raw material is put into the reactor body 1 through the feed pipe 3. Then, the motor 9 is started to drive the rotating shaft 10 to rotate, which in turn drives the turntable 11 to rotate. The turntable 11 drives the drive pin 12 to rotate in a circle. During the rotation of the drive pin 12, the cooperation with the strip groove 14 causes the connecting plate 13 to drive the moving plate 6 to reciprocate in the vertical direction, thereby causing the moving plate 6 to drive the stirring rod 7 and the stirring blade 8 to reciprocate synchronously.

[0036] As the stirring rod 7 moves back and forth, it drives the sleeve 15 to move back and forth synchronously. Under the action of the twisted rod 16, the sleeve 15 moves back and forth and rotates back and forth, so that the stirring rod 7 and the stirring blade 8 rotate back and forth synchronously. This ensures that the stirring rod 7 and the stirring blade 8 move back and forth and rotate back and forth simultaneously, thereby improving the mixing effect and efficiency of the polyurethane adhesive.

[0037] When the rotating shaft 10 rotates, it drives the rotating rod 18 to rotate through the bevel gear set 17. This causes the rotating rod 18 to drive the driving gear 19 to rotate, which in turn causes the driven gear 20, which meshes with the driving gear 19, to drive the hollow tube 21 to rotate. This, in turn, causes the hollow tube 21 to drive the straight rod 22 and the scraper 23 to rotate, thereby scraping and cleaning the inside of the vessel body 1 and preventing the polyurethane adhesive material from adhering to the inner wall of the vessel body 1. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
