Embodiment Construction

[0032] Refer to attached figure 2 , the DC motor 8 is connected with the reducer 7 and all the control systems are installed in the inner tube 2, the reducer 7 is connected with the driving wheel 6, and the driving wheel 6 drives the roller shell 5 to rotate, and the left end of the roller is driven by the rotating wheel 3. The double bearing 4 and the end cap 1 are connected with the fixed bracket. The main components of the control part are installed on the bracket 12, and the implementation method of the control mechanism is as follows: the roller shell 5 drives the guide wheel 17, the guide wheel 17 drives the gear 15 to work, and a digital positioning disc 18 and a digital positioning detector 14 are installed at one end of the gear shaft. The work of the digital positioning disc 18 and the digital positioning detector 14 can accurately locate the roller in the working process. The pinion shaft 15 drives the transmission rod 16 to work through the screw transmission, and...
