Automatic roll replacing device, and winding equipment

A winding equipment, comprising an automatic roll replacing device, comprising:

• a mounting frame;
• an unwinding mechanism comprising an unwinding shaft rotatably connected to the mounting frame around its own axis;
• a spare material mechanism comprising a spare material shaft having a contact end and a material pushing member providing axial pushing force for a spare material roll on the spare material shaft;
• the spare material shaft is rotatably connected to the mounting frame around a rotation axis;
• a material pushing position is provided during a process of the spare material shaft rotating around the rotation axis, when the spare material shaft is located at the material pushing position, the contact end connects with the unwinding shaft, the material pushing member is controlled to push the spare material roll on the spare material shaft to transfer to the unwinding shaft;
• and
• a strip connection mechanism, provided on the mounting frame, and used to cut off a work material strip unwound from the unwinding shaft and connect a cut-off work material strip to the spare material roll;
• wherein
• the unwinding mechanism further comprises a first guiding post and a rotating shaft, the first guiding post is movably connected to the mounting frame along its own axis, the rotating shaft is fixed in an axial direction and is rotatably fitted in the first guiding post in a circumferential direction, the unwinding shaft is fixedly connected to one end of the rotating shaft.
