Background technology
Commonly use drum-type cut-tobacco drier in tobacco cutting production process, there are one enter for steam in cylinder on cut-tobacco drier
Cooling fin and condensed water output critical piece --- rotary joint, its outer, stationary is motionless, and inner tube is done with roller to be rotated
Movement causes rotary joint inner tube to form radial direction with shell due to body centre and rotary joint central coaxial degree source of error
Relative motion exacerbates the damage of rotary joint inner seal.Cut-tobacco drier is that cylinder is connect steam with rotary joint at present
Pipe is connected with condensate pipe in the form of hose, and the power of rotary joint inner tube rotation makes cylinder in a radial manner by a whippletree
Body outlet edge is connect with rotary joint end center, although rotary joint can be made to rotate and rotate with roller, it is to rotation
Connector rotation is the passing power in a manner of " agitating ", will if by chance cylinder circular runout when whippletree goes to horizontal position
The power that a radial direction is formed to rotary joint inner tube, causes centainly to damage to rotary joint in this way, therefore increases rotary joint damage
The bad frequency affects equipment normal operation, is adversely affected to product quality, increases maintenance cost.Original design rotation connects
Head fixed form constrains rotary joint fixed part excessive, and rotary joint generates vibration at runtime, with the rotation of roller,
The generation of swivel head inner tube radially wobbles, and exacerbates the abrasion of central tube inner sleeve, causes to gang up into vapour and return water, to the meeting that runs well
Generate strong influence.

It is fixedly connected to section one end, the universal joint other end is equipped with cardan axis to trough of belt sliding sleeve (length adjustment guide sleeve 9), and is set to cylinder
The fixed frame connection of body outlet, universal center connector are equipped with from straightening spring.When work, come from the dynamic of cylinder rotation
Power is transmitted on universal joint axial trough of belt sliding sleeve and passes to cardan axis, then by being located at four by cylinder and universal joint connector
On a spherical movable joint, the joint axis pin of the mutually multiple angles in space is transmitted to the universal joint other end and swivel connection
To rotary joint.
Which when barrel body rotation generates circular runout, no matter in angle generation circular runout, can all be disappeared by spherical joint
It removes, when cylinder because when heated axial length changes, trough of belt sliding axle (the third ball-joint housing in axial trough of belt sliding sleeve
16) this length will be being eliminated under the effect of straightening spring, guarantee will not change because of barrel lenght, lead to universal joint
Axis joint generates larger flexible deformation, ensures the almost coaxial degree between each joint as possible, it is ensured that by cylinder in a manner of couple
Body rotary force is transmitted to rotary joint inner tube, reduces the generation of inner tube radial load, and then reduces the rotary joint damage frequency, saves
Maintenance cost reduces production downtime.
In conclusion present disclosure is not limited in the above embodiments, those skilled in the art can be
It is proposed other embodiments within the technological guidance's thought of the present invention, but these embodiments be included in the scope of the present invention it
It is interior.
