A plurality of guide grooves are provided on the outer side of the fixed cylinder 21, and the guide strips 23 are slidably arranged in the guide grooves. It can be seen that the fixed cylinder 21 and the inner threaded column 22 can only move linearly relative to each other. A spring 27 is provided between the stirring and the inner threaded column 22 to fix the two. The first bevel gear 24 in each group of stirring structures is meshed with a second bevel gear 25. Each second bevel gear 25 is coaxially fixed with the fixed rod 14, and each upper and lower adjacent second bevel gears 25 are arranged relatively to each other. The inner threaded columns 22 in the two upper and lower adjacent stirring structures move in opposite directions.
[0025] The driving assembly 17 is connected to the rotating cylinder 28 , and the rotating cylinder 28 is rotated in forward and reverse axial directions through the driving assembly 17 .
[0026] Preferably, the support assembly includes a plurality of support columns 2 for supporting, and one end of the support column 2 is fixed to the bottom of the reaction cylinder 1 .
[0027] Preferably, a universal wheel 3 for movement is fixed to the bottom end of the support column 2 .
[0028] Preferably, a feed pipe 5 connected to the bottom of the reaction cylinder 1 is fixed, and the feed pipe 5 is used to discharge the pressure-sensitive adhesive after the reaction. The bottom end of the feed pipe 5 is equipped with an electromagnetic valve 4 for opening and closing.
[0029] Preferably, a plurality of hangers 6 are fixed on the top of the reaction tube 1, and the hangers 6 are provided to facilitate the crane to lift the entire reactor.
[0030] Preferably, a cavity 13 is opened inside the reaction cylinder 1, and a liquid inlet pipe 20 and a discharge pipe 19 connected to the cavity 13 are fixed on the outside of the reaction cylinder 1. Hot liquid enters the cavity 13 from the liquid inlet pipe 20 and is discharged from the discharge pipe 19, so that the hot liquid heats the reaction cylinder 1 inside the cavity 13.
[0031] Preferably, the driving assembly 17 includes a servo motor 10, a disc 11, a connecting rod 12, a rack 9, a guide rail 8 and a transmission gear 15. The housing of the servo motor 10 is fixed on the reaction cylinder 1, the output shaft of the servo motor 10 is coaxially fixed with the disc 11, the guide rail 8 is fixed on the reaction cylinder 1, the entire sliding sleeve of the transmission gear 15 is arranged on the guide rail 8, the transmission gear 15 is coaxially fixed with the rotating cylinder 28, the transmission gear 15 is meshed with the rack 9, the two ends of the connecting rod 12 rotate at the non-center of the disc 11 and on one end of the rack 9 respectively, the servo motor 10 drives the disc 11 to rotate axially through the output shaft, the disc 11 makes the rack 9 reciprocate along the guide rail 8 through the connecting rod 12, the rack 9 drives the transmission gear 15 to move reciprocatingly, and the transmission gear 15 drives the rotating cylinder 28 to rotate reciprocatingly.
[0032] Working principle: The raw material is placed in the reaction cylinder 1, and the servo motor 10 drives the disc 11 to rotate axially through the output shaft. The disc 11 makes the rack 9 move back and forth along the guide rail 8 through the connecting rod 12. The rack 9 drives the transmission gear 15 to move back and forth. The transmission gear 15 drives the rotating cylinder 28 to rotate back and forth axially. The rotating cylinder 28 and the fixed rod 14 rotate relative to each other. The first bevel gear 24 in the stirring structure is driven by the second bevel gear 25. Since the rotating cylinder 28 rotates forward and backward, the first bevel gear 24 rotates forward and backward, and the second bevel gear 25 rotates forward and backward. A bevel gear 24 drives the threaded column 26 to rotate forward and backward, so that the internal threaded column 22 moves back and forth along the fixed cylinder 21. Every two adjacent second bevel gears 25 are arranged relatively to each other, so that the upper and lower adjacent internal threaded columns 22 move in opposite directions. It can be seen that the upper and lower adjacent stirrings are staggered with each other, one on the inside and the other on the outside, and the stirring speeds of the inner and outer sides at different heights are inconsistent, thereby realizing differential stirring. When the forward rotation rotates to the reverse rotation, the speed instantly returns to zero. At this time, the spring 27 vibrates due to inertia, thereby vibrating and stirring the raw materials.
[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
