The cleaning rod 22 and the square shell 21 are connected by the first spring, so that when the cleaning rod 22 is worn, it can still clean the inner side wall of the barrel 1 under the elastic force of the first spring, thereby prolonging the service life of the cleaning rod 22. The outer side wall of the pair of cleaning wires 23 is in contact with the outer side wall of the pair of stirring rods 10, so that when the stirring rod 10 rotates, the raw materials adhering to the stirring rod 10 are cleaned by the cleaning wire 23 under the rotation of the stirring rod 10, thereby preventing the raw materials from adhering to the outer surface of the stirring rod 10 during stirring, further reducing the waste of raw materials, and reducing the production cost of the syringe sheath. A group of first through grooves 24 are formed in the outer side wall of the stirring rod 10, and an auxiliary plate 25 is slidably connected to the inner side wall of the first through groove 24, so that the auxiliary plate 25 can increase the stirring range of the stirring rod 10 and improve the stirring effect when the stirring rod 10 stirs. When the auxiliary plate 25 encounters the cleaning wire 23 under the rotation of the stirring rod 10, the outer side wall of the cleaning wire 23 first encounters the second inclined surface 27 on the auxiliary plate 25. When the second inclined surface 27 encounters the cleaning wire 23, the end of the auxiliary plate 25 that encounters the cleaning wire 23 contracts, so that the cleaning wire 23 gradually contacts the first inclined surface 26 through the second inclined surface 27. Thus, the overall structure of the first inclined surface 26, the second inclined surface 27, and the auxiliary plate 25 makes the end that encounters the cleaning wire 23 contract and the end that does not encounter the cleaning wire 23 extend, thereby making the auxiliary plate 25 always have a stirring effect. When the auxiliary plate 25 slides left and right under the rotation and stirring of the stirring plate, a group of third tooth grooves 29 are formed on one side of the outer wall of the auxiliary plate 25, a third gear 31 is fixedly connected to the outer side wall of the third circular rod 30, and the third gear 31 and the third tooth groove 29 are in meshing connection, so that the left and right sliding of the auxiliary plate 25 drives the third gear 31 to rotate, the rotation of the third gear 31 drives the third circular rod 30 to rotate,The rotation of the third round rod 30 drives a pair of vibration rods 33 and vibration balls 34 to rotate. Since the vibration rods 33 are connected to the third through slot on the third round rod 30 through the third spring, when the vibration rods 33 and the vibration balls 34 follow the rotation of the third round rod 30, the vibration balls 34 on the vibration rods 33 will knock on the outer wall of the auxiliary plate 25 and the inner wall of the vibration groove 28, so as to make the auxiliary plate 25 and the stirring rod 10 vibrate. Since the stirring rod 10 and the auxiliary plate 25 add vibration during stirring, the vibration can effectively break the agglomeration of the material, increase the contact area, and make the particles collide with each other, so as to quickly mix and improve the mixing efficiency. Through the double action of vibration and stirring, the particles move in three-dimensional space, realize the effective combination of macroscopic convection and microscopic diffusion, achieve better homogenization effect, effectively improve the mixing efficiency, improve the homogenization effect, shorten the stirring time, and improve the output efficiency.
