Next, the tail ends of the two claws 34 are hinged to the mounting base 33, and each claw 34 is configured with a telescopic driving unit 341 for driving the claws to open and close and mounted on the mounting base 33. Therefore, the connecting seat 32 can swing up and down relative to the sliding seat 31 and the mounting seat 33 can swing left and right relative to the connecting seat 32, so that the clamping claw 34 can swing up and down and left and right to adapt to the condition of non-concentricity between the clamping claw 34 and the pulled mandrel, and the clamping claw 34 can swing independently and finely during the shaft pulling process so as to be concentric with the pulled mandrel.
Further, the connecting seat 32 is provided with two limit screws 35 (the limit screws are sleeved with pressure springs to play a role of elastic buffering) located at the left and right sides of the vertical shaft, wherein one of the limit screws 35 can be in limit contact with the mounting seat 33 when the mounting seat 33 and the connecting seat 32 swing relatively leftwards and rightwards, and therefore the mounting seat 33 is limited and contacted in a bilateral swing direction through the two limit screws, and excessive swing is avoided.
Further, the telescopic driving unit 341 preferably employs a telescopic cylinder, and the end of the telescopic rod is hinged to the claw 34. The claw 34 is driven to swing through the telescopic action, namely, when the telescopic rod of the telescopic driving unit 341 is extended, the claw 34 swings outwards; conversely, when the telescopic rod of the telescopic driving unit 341 is contracted, the claw 34 swings inward. Thus, the two groups of telescopic driving units 341 can realize the synchronous opening and closing actions of the two claws 34.
In this embodiment, the lifting frame is connected to the fixed frame in a sliding manner along a vertical direction, and the sliding seat is connected to the lifting frame in a sliding manner along a horizontal direction, wherein, for improving the stability of sliding connection, a guide rail and a sliding block which are matched with each other in a sliding manner can be additionally arranged between the lifting frame and the fixed frame and between the sliding seat and the lifting frame. Next, the driving device of the present embodiment includes a vertical driving unit 41 disposed on the fixed frame 1 and used for driving the lifting frame 2 to move vertically, and a lateral driving unit 42 disposed on the sliding seat 31 and used for driving the sliding seat 31 to move laterally.
Further, the transverse driving unit 42 includes a transverse driving motor 421 and a transmission gear 422 drivingly connected to the transverse driving motor 421, where the transmission gear 422 is meshed with the guide rack 22 preset on the lifting frame 2 and extending in the transverse direction, and the transverse driving motor 421 drives the transmission gear 422 to perform a rotation motion, and the meshing transmission between the transmission gear 422 and the guide rack 22, so as to implement a transverse movement of the sliding seat 31 relative to the lifting frame 2, and further make the claw 34 move transversely in synchronization therewith.
Further, the vertical driving unit 41 includes a vertical driving motor 411, two sets of driving chains 412 vertically arranged and in driving connection with the vertical driving motor 411, two ends of the lifting frame 2 are respectively connected to the two sets of driving chains 412, wherein an output shaft of the vertical driving motor 411 extends to form a chain wheel shaft meshed with the two sets of driving chains 412, and thus the two sets of driving chains 412 are driven to synchronously and circularly move by one vertical driving motor 411, and further the lifting frame 2 is driven to vertically move.
In summary, the pulling shaft operating device 3 and the clamping jaw 34 are driven to move transversely and vertically by the transverse driving unit 42 and the vertical driving unit 41, so that the clamping jaw 34 approaches to or separates from the mandrel, and the mandrel is pulled by the clamping jaw 34.
In this embodiment, when the driving device drives the shaft pulling operation device 3 to approach and axially align with the preset mandrel, the front end of the claw 34 in the clamping state can clamp the preset mandrel end and is engaged with the clamping groove preset at the mandrel end. Secondly, after the clamping claw 34 embraces the end of the mandrel, the mandrel is pulled out of the rewinding paper roll axially by driving the pulling-out shaft operating device 3 and the clamping claw 34 to move transversely through the transverse driving unit 42 of the driving device.
In this embodiment, the lifting frame 2 is provided with a plurality of supporting rollers 21 horizontally arranged along the transverse direction and used for supporting the pulled-out mandrel, and each supporting roller 21 is horizontally arranged at the same level so as to be convenient for receiving the pulled-out mandrel.
