Referring to fig. 1-5, an embodiment of the present utility model is provided: an automatic rewinding machine comprises a frame 1, a supporting table 3 arranged below the frame 1, a rewinding station 2 arranged inside the frame 1 and a feeding mechanism 5 arranged outside the frame 1; the supporting table 3 is provided with a first pushing plate 33 and a second pushing plate 35; wherein the first pushing plate 33 pushes the paper roll positioned on the rewinding station 2 out of the rewinding station 2, and the second pushing plate 35 pushes the paper roll onto the rewinding station 2; the feeding mechanism 5 comprises a containing box 50; wherein, the upper end and the lower end of the containing box 50 are respectively provided with a driving shaft 52, and two sides of the driving shafts 52 are respectively provided with a chain wheel 53, and are connected with the chain wheels 53 through a chain so as to drive a feeding plate 51 arranged on the chain to circularly rotate between the two driving shafts 52.

In summary, the feeding plate 51 rotates along with the sprocket 53, so the paper roll in the accommodating box 50 can be pushed to the second pushing plate 35, then the paper roll is pushed onto the rewinding station 2 by the second pushing plate 35, after the rewinding is finished, the paper roll after the rewinding is pushed out of the rewinding station 2 by the first pushing plate 33, based on this, the device realizes automatic feeding of the paper roll by the feeding mechanism 5, and the automatic feeding and automatic pushing of the paper roll to the rewinding station 2 are completed by the cooperation of the first pushing plate 33 and the second pushing plate 35, so the rewinding efficiency of the paper roll can be improved. In addition, the auxiliary workload of operators is greatly reduced in the rewinding process, so that the investment of labor cost can be reduced.

Further, since the frame 1 is also provided with a guide piece 4; the guide 4 includes a connection plate 43 fixedly connected to the frame 1, and a guide frame 44 for guiding the paper roll to move toward the rewinding station 2 is disposed on the connection plate 43, so that the paper roll can be guided to move toward the rewinding station 2 by the guide 4, and at the same time, the paper roll slides in the guide frame 44, so that the paper roll can be prevented from falling during movement.
