Embodiment:
Embodiment, see as shown in Figure 1 to Figure 3, a kind of cloth conveying adjustable driving roller device, including transmission bracket bottom
Plate 10, the top surface both sides of the transmission bracket bottom plate 10 are hinged with vertical stud 11, and the top of vertical stud 11 is screwed onto lifting
In the center screw of swivel nut 12, the top of lifting swivel nut 12 is fixed on upper backup pad 13, is provided between two upper backup pads 13
Upper live-roller 14 and lower driving roller 15, the both ends of upper live-roller 14 are hinged on the top of two upper backup pads 13, lower driving roller 15
Both ends be hinged on two movable blocks 151, the regulation groove 141 that the sleeve of movable block 151 has at the middle part of upper backup pad 13
In, regulating block 152 is fixed with the lateral wall of movable block 151, regulating block 152 is screwed onto in adjusting screw rod 153, adjusting screw rod
153 both ends are hinged in two regulation supporting plates 154, and two regulation supporting plates 154 are fixed on the lateral wall of upper backup pad 13
Go up and be in above and below regulation groove 141, be fixed with regulation motor 155 in one of regulation supporting plate 154, adjust
The output shaft of motor 155 is splined shaft, and splined shaft sleeve is in the splined hole that one end of adjusting screw rod 153 has.
Further, the top end face of the movable block 151 and bottom surface are respectively and fixedly provided with buffer spring 1, buffer spring 1 it is another
One end is fixed on corresponding top surface or the bottom surface of regulation groove 141.
Further, tie-beam 121 is provided between the top of two lifting swivel nuts 12, the both ends of tie-beam 121 are fixed
On the upper outside wall of lifting swivel nut 12.
Further, self-lubricating layer 156 is fixed with the madial wall of the opposite regulation groove 141 of the movable block 151, from
Lubricating layer 156 is pressed against on the madial wall of regulation groove 141.
