Summary of the invention
The purpose of this utility model provides the sending band, move back band of a kind of compress, fastening belt device.
For this reason, the utility model is by the following technical solutions: it comprises send the band driving wheel, moves back band driving wheel, fastening belt driving wheel, describedly send the band driving wheel, move back band driving wheel and fastening belt driving wheel and be the angular position relation, the described band driving wheel that send is in the below of sending the band track, moves back the band driving wheel and is in the below of sending the band track; Described device is provided with and send band, moves back the main motor of band work, and described device is provided with tape handler or chain drive, described main motor by described tape handler or chain drive with describedly send the band driving wheel, move back the band driving wheel and be connected.
When adopting technique scheme, further technical scheme below the utility model also can adopt or make up and adopt:
Described device also is provided with the main shaft that drives the cam rotation, described tape handler or chain drive are by main motor and the interaxle first order tape handler of described master or chain drive and main shaft and send second stage tape handler or the chain drive being with driving wheel and moving back between the band driving wheel to constitute, have power-transfer clutch between described main shaft and first order tape handler or the chain drive, described second stage tape handler or chain drive are speedup tape handler or chain drive.
Send band driving wheel, fastening belt driving wheel and move back the band driving wheel, be followed successively by and send band driving wheel, fastening belt driving wheel and move back the band driving wheel, the described top of sending the fastening belt driving wheel to be in to send the band track by the front and back position that send the band direction.
Owing to adopt the technical solution of the utility model, can reduce motor start-stop action, motor is improved service life.The utility model can drive with a motor and send band, move back band work, and start-stop and frequent rotating work can improve the life-span of motor and the working stability of compress continually.
