The compression spring 212 provided on the lower plate surface of the front tray 21 is rapidly compressed when the weight of the paper is heavy, and the elastic force is large, but the tension spring 214 can be selected to be small, and the tension of the tension spring 214 is maximum in this state, but the contribution of the elastic force of the tension spring 214 to the whole is small because the selection of the tension spring 214 is small. With the reduction of paper processing, the weight is reduced, the pressure spring 212 is gradually rebounded and restored, the elastic force is gradually reduced, when the final range of about 1-40 sheets is reached, the elastic force of the pressure spring 212 approaches zero, and the tension springs 214 on the left side and the right side play a main role at the moment, so that the pressure between the paper at the paper feeding end of the front dragging tray 21 and the paper twisting surface of the paper twisting wheel 62 can meet the paper twisting requirement under the condition of more paper sheets and under the condition of less paper sheets.
When cutting paper materials, the end part of printing paper sometimes deforms, slightly tilts, when positioning and die cutting are carried out, the paper can move back and forth, due to the end part warping, the front end of the paper is damaged and curled when the paper enters a pinch roller, the paper pressing device 32 cannot well press the paper, and the phenomena of paper deformation, positioning dislocation, paper jamming and the like can be caused, so that the machine die cutting dislocation or shutdown alarm is caused. Therefore, the paper pressing reeds are provided on both the front and rear row of paper presses 32 in order to increase the smoothness of the entry of the paper sheets of different hardness.
