In addition, because the machine does not need to be turned on and off frequently, the correction times of the punch press are correspondingly reduced, and the production efficiency of the punch press can be further improved. Meanwhile, the machine does not need to be turned on and off frequently, the correction times of the punch press are correspondingly reduced, the consistency of the punched products can be effectively improved, the consistency of the punched products can be improved, and the yield of the products can be improved.

In a preferred embodiment, a drive mechanism 103 is coupled to the slip transfer member 102 for driving the slip transfer member 102 in rotation. The paper strip transferring piece 102 is driven to rotate by the driving mechanism 103 so as to drive the paper strips to be transferred, the transferring direction of the paper strips is convenient to adjust, and the compactness of the whole structure of the stamping paper feeding mechanism is improved. In addition, the paper slip transferring piece 102 is driven to rotate by the driving mechanism 103 so as to drive the paper slip to be transferred, and the paper slip transferring piece is convenient to match with other elements, so that the purpose of transferring the paper slip is achieved.

In one particular example, the housing 101 has a cavity 1011. The counter, the controller 104 and the driving mechanism 103 are all positioned inside the cavity 1011; paper roll mounting member 110 and paper strip transfer member 102 are both located outside of chamber 1011. Further, paper roll mounting member 110 is positioned on the outer top of cavity 1011 and paper strip transfer member 102 is positioned on the outer side of cavity 1011.

As a preferred solution, the paper feeding mechanism 100 of the punching machine further comprises a second paper roll limiting member; a second roll stop is attached to the roll mount 110 for defining the axial position of the roll 200. The second roll limiting member prevents the roll 200 from being displaced in the axial direction, thereby improving the stability of the roll 200. Further preferably, the second paper roll limiting member is sleeved on the outer edge of the paper roll mounting member 110. The second paper roll limiting member is sleeved on the outer edge of the paper roll mounting member 110, so that unnecessary displacement of the paper roll 200 in the axial direction can be effectively avoided. In one particular example, a roll mount 110 extends through the second roll stop. The second roll paper limiting member is sleeved on the outer edge of the roll paper mounting member 110.

It will be appreciated that, when paper roll 200 is installed, the second roll stop is removed, paper roll 200 is installed on paper roll mounting member 110 with paper roll 200 located in the area defined by first roll stop 105, and then the second roll stop is fitted around the outer edge of paper roll mounting member 110 to stop the axial direction of paper roll 200.

The pressure plate 106 can improve the limiting effect of the second paper roll limiting part on the paper roll 200, and the stability of the paper roll 200 is improved. Preferably, the platen 106 is circular in radial cross-section. More preferably, the area of the radial cross section of the platen 106 is not smaller than the area of the radial cross section of the paper roll 200, and at this time, the platen 106 can completely press the paper roll 200, further improving the stability of the paper roll 200. More preferably, the area of the radial cross-section of the platen 106 is not smaller than the area of the area enclosed by the first roll stop 105.
