[0025] like Figure 2 , 3 As shown in Figure 4, the counterweight assembly includes a counterweight rod 9, a counterweight block 10 and an adjusting screw 11. The counterweight rod 9 is slidably penetrated in the balance groove 8, the counterweight block 10 is penetrated on the counterweight rod 9, the counterweight rod 9 is slidably penetrated in the sliding groove 7, the end of the counterweight rod 9 extends out of the outside of the balance block body 4, the end of the counterweight rod 9 is provided with two limit plates, the two limit plates respectively abut against the inner and outer side walls of the sliding groove 7, the counterweight block 10 is penetrated on the counterweight rod 9, the end of the counterweight rod 9 is provided with an adjusting nut 12, the adjusting screw 11 is threadedly connected to the adjusting nut 12, the front end of the adjusting nut 12 abuts against the outer wall of the beating shaft 1, and the adjusting nut 12 is fixed Fixed on the outside of the limit plate, the upper and lower ends of the counterweight block 10 are respectively fixed with balance springs 13, and the balance springs 13 on both sides are respectively fixed on the upper and lower inner walls of the balance groove 8, the adjusting screw 11 is in contact with the outer wall of the positioning sleeve 3, and the end of the adjusting screw 11 is provided with a spherical groove, and the end of the adjusting screw 11 is threadedly connected to a limit ring 14, and a resistance ball 15 is rotatably connected in the spherical groove, and the front end of the resistance ball 15 protrudes from the spherical groove, and the limit ring 14 is clamped on the outer wall of the resistance ball 15, and the resistance ball 15 is in contact with the outer wall of the positioning sleeve 3.

[0026] Working principle:
[0027] The adjusting screw 11 of the utility model can be used to adjust the initial distance between the counterweight rod 9 and the positioning sleeve 3 by rotating the adjusting nut 12, so as to adjust the optimal counterweight balance in the initial state. During the rotation of the beating-up shaft 1, the balancing block mechanism rotates as a whole. During the rotation, the abutment ball 15 at the end of the adjusting nut 12 abuts against the outer wall of the positioning sleeve 3. When the beating-up shaft 1 swings unbalanced and eccentric vibration occurs on the beating-up shaft 1, an eccentricity difference will appear between the beating-up shaft 1 and the positioning sleeve 3. Under the action of the balancing spring 13, the adjusting screw 11 of the counterweight assembly always abuts against the outer wall of the positioning sleeve 3, that is, the adjusting screw 11 will synchronously extend and retract with the eccentricity difference between the beating-up shaft 1 and the positioning sleeve 3, that is, the position of the counterweight assembly on the balancing block body 4 is changed, and then the overall center of gravity of the balancing block body 4 is adjusted, so that the beating-up shaft 1 reaches a dynamic balance state, avoids the vibration of the two sides of the beating-up shaft 1 in the swinging state due to uneven acceptance, and ensures the smooth operation of the beating-up shaft 1.
