The vibration mechanism of existing vibrating mixers includes a mixing shaft and a transmission shaft. The transmission shaft is connected to one end of the mixing shaft through a floating bearing. The transmission shaft and the mixing shaft are eccentrically arranged. When the mixing shaft rotates, the transmission shaft rotates at a high speed, thereby causing the mixing shaft to vibrate.

[0032] One end of the stirring shaft 3, namely the outer end section of the non-power end shaft section 301, is the non-power end, and the other end of the stirring shaft 3, namely the outer end section of the power end shaft section 303, is the power end.

The spatial meshing relationship between the inner transmission teeth 603 and the outer transmission teeth 604 is achieved by staggered arrangement in which the inner transmission teeth 603 and the outer transmission teeth 604 do not contact each other.

Of course, the power end shaft head 320 may not be fixedly connected to the stirring shaft 3, and the power end support shaft 7 may be inserted in the inner sleeve 602. Then, the outer sleeve 601 may be inserted in the inner cavity of the stirring shaft 3, or the outer sleeve 601 may also be connected to the stirring shaft 3 through a flange.

[0037] Reference Fig.12 In order to prevent the axial displacement of the stirring shaft during the stirring process from causing impact on the power end support shaft 7, a power end buffer pad 11 is provided between the power end of the stirring shaft 3 and the inner end of the power end support shaft 7; the structure of the power end buffer pad 11 is the same as that of the non-power end buffer pad 10. A power end connecting disk 22 with an axial through hole is connected to the end face of the power end of the stirring shaft 3, that is, the end face of the power end shaft head 320, the plug column 19 on one side of the power end buffer pad 11 is inserted into the axial through hole of the power end connecting disk 22, and the plug column 19 on the other side of the power end buffer pad 11 is inserted into the inner cavity of the power end support shaft 7, and the pad body 18 is located between the power end connecting disk 22 and the power end support shaft 7. Refer to Fig.12The outer end of the inner cavity of the power end connecting sleeve 9 is radially convex inward to form a positioning ring 92, and the outer sleeve 601 of the elastic coupling device 6 is against the positioning ring 92. The setting of the positioning ring 92 can form a gap between the elastic coupling device 6 and the inner end of the power end support shaft 7, and the power end connecting disk 22 is not in contact with the power end support shaft 7 and the power end flange 91, so that the cushion body 18 can be fully utilized to buffer the impact of the axial force generated by the stirring shaft 3 during the stirring process on the power end support shaft 7. In addition, an air outlet 93 is provided on the positioning ring 92, and the air outlet 93, the above-mentioned gap and the air vent 606 of the elastic coupling device 6 form an air circulation channel to facilitate the cooling of the elastic connector 605 of the elastic coupling device 6.

[0038] The inner transmission teeth 603 and the outer transmission teeth 604 of the elastic coupling device do not directly contact each other when transmitting power to each other, but the power is transmitted between the inner transmission teeth 603 and the outer transmission teeth 604 through the elastic connecting body 605 between the inner transmission teeth 603 and the outer transmission teeth 604. Under the buffering effect of the elastic connecting body 605, the vibration of the stirring shaft is not easily transmitted to the power end support shaft 7 and the non-power end support shaft 2. The vibration will fully act on the material being stirred, thereby improving the vibration stirring effect.

The above-mentioned vibration mechanism is connected to the frame 30 through its non-power end bearing seat 1 and power end bearing seat 4. The non-power end bearing seat 1 is fixedly connected to the frame and is located outside the non-power end of the stirring box 31. The power end bearing seat 4 is fixedly connected to the frame and is located outside the power end of the stirring box 31. The stirring shaft 3 of the vibration mechanism is located in the stirring box 31. A plurality of stirring blades 35 are fixedly installed on the stirring shaft 3. The power end support shaft 7 of the vibration mechanism is connected to the stirring shaft driving device. When in use, the transmission cable is electrically connected to the electric slip ring 13 to supply power to the vibration motor in the stirring shaft 3, and the vibration motor and the stirring motor of the stirring shaft driving device 32 are started, so that the material in the stirring box 31 can be vibrated and stirred. During the stirring process, the air can be sent into the vicinity of the vibration motor 5 in the stirring shaft through the rotating joint 16 of the vibration mechanism, the inner cavity of the non-power end support shaft 2 and the air inlet pipe 14 by the air supply device, so as to ventilate and dissipate heat for the vibration motor 5, and the air that absorbs heat is discharged through the exhaust hole 17 on the stirring shaft 3. Fig.14Only one set of vibration mechanism is shown. In order to improve the mixing efficiency, the vibration mixer can be provided with two sets of vibration mechanisms. A synchronous gear should be installed on each of the power end support shafts 7 of the two sets of vibration mechanisms. The two synchronous gears are meshed with each other to realize the synchronous rotation of the two mixing shafts.
