<p>A strip feeder includes a frame (21), a driving device (22), a driving roller group (23) and a pressure roller group (24) both parallel in group. The driving device (22), the driving roller group (23) and the pressure roller group (24) are mounted on the frame (21). The driving device (22) is connected with the driving roller group (23) to rotate the driving roller group (23), the pressure roller group (24) and the driving roller group (23) are disposed in pairs, and the holding force of the pressure roller group (24) on the strip (1) is changed by an adjusting device. The driving roller group (24) includes driving rolls (231) and driven rolls (232) which respectively comprise an inner;ore (2301), a rotating shaft (2302), a sleeve (2303) from inside to outside. The rotating shaft (2302) is supported on the inner core (2301) through bearings on both ends, the sleeve (2303) is coated on the rotating shaft (2302) and provided with at least one V-belt groove where a V-belt (2304) is arranged and contacts with the strip surface, and the outer layer of the V-belt (2304) is provided with wrapping cloth. The driving rolls (231) are connected with the driving device (22), and the driven rolls (232) and the driving rolls (231) corporately enable the V-belt to be tensioned.</p> |
