The paper laying adsorbed on the paper sucking liner 8 is driven to move by the sliding frame 6 a.

The upper surfaces of the bottom plates 6 on the two sides of the first guide rail 6t are respectively provided with an upright post 6d, and the axes of the upright posts 6d are vertically distributed with the upper surfaces of the bottom plates 6. The top of the two upright posts 6d above the paper sucking cavity 6c is bridged with a supporting plate 6e, and the supporting plate 6e is parallel to the bottom plate 6.

The pallet 6e is provided with a second rail 6f, and the axis of the second rail 6f is parallel to the first rail 6 t. The second guide rail 6f is provided with a corresponding matched sliding block 6g, one end of the second guide rail 6f is provided with a second telescopic device 6h corresponding matched with the sliding block 6g, and the second telescopic device 6h is an air cylinder.

When the sensor senses that the diameter of the corresponding right paper laying roll is reduced to a certain value, a signal is sent to the control module.

And then the control module controls the movable sliding frame in the left paper cutting and feeding assembly to move to the right side, so that the pull-out end of the left paper laying roll adsorbed on the paper suction cavity is adhered to the paper laying led out by the right paper laying roll.

And then the control module controls the vacuum generator of the left paper cutting and feeding assembly to stop, and the sliding frame is reset to the left side, so that auxiliary paper pulled by the left paper laying roll is released.

And then the control module controls the second telescopic device in the right paper cutting and feeding assembly to start the pushing sliding block to move leftwards, and the extending paper laying cutting knife cuts off the running-out paper laying which is led out by the right paper laying roll. Thereby completing the switching of the left and right paper rolls.

Finally, the control module sends out a signal to inform the staff to replace a new right-side paper laying roll, the pulling end of the right-side paper laying roll is pulled out, and the right-side paper cutting and feeding assembly is vacuum-adsorbed and fixed through a paper sucking cavity in the right-side paper cutting and feeding assembly, and the next switching of the left-side paper laying roll and the right-side paper laying roll is waited.
