When the paper feeding box works, firstly, the raw paper 21 is added into the paper feeding box 1, the adhesive is added into the storage tank 46, the motor 51 is started, the motor 51 drives the driving roller 14 to rotate through the motor shaft, so as to drive the conveyor belt 15 to rotate, the supporting rod 22 can enable the second connecting plate 18 to press the first rotating rod 19 under the action of the first spring 17, so that the suction cup 26 sucks the raw paper 21, when the conveyor belt 15 rotates until the first gear 20 is positioned on one side of the first rotating rod 19, the first gear 20 can slowly jack up the first rotating rod 19, so that the suction cup 26 sucks the raw paper 21 until the push rod 25 is slowly contacted with the fixed plate 23, the push rod 25 pushes the rubber plug 27, so that the suction cup 26 loosens the raw paper 21, so that the raw paper 21 falls between two groups of first gear 20 on the conveyor belt 15, the second gear 30 can be meshed with the third gear 50 to drive the pressing roller 32 to rotate, when one group of first gear 20 moves to the movable groove 39, the first gear 20 pushes the cutter 40 on the right side of the sliding rod 33 to rotate, so that the cutter 40 cuts off the left end corner part of the raw paper 21 and the plastic film between two groups of the first gear 20, the conveyor belt 15 continues to move, the first gear 20 pushes the cutter 40 on the left side of the sliding rod 33 to rotate, so that the cutter 40 cuts off the right end corner part of the next raw paper 21 and the plastic film, so that the left side corner part and the right side corner part of the coated paper are neat, meanwhile, the first gear 20 presses the sliding rod 33, the third spring 34 extends, so that the sliding rod 33 presses the tympanic membrane 35 on the joint pipe 36, the space in the joint pipe 36 is reduced, so that the adhesive in the joint pipe 36 is sprayed out of the spray head 31 onto the raw paper 21 on the lower conveyor belt 15 through the first connecting pipe 29 and the first check valve 45, when the first gear 20 moves away from the press roller 32, the clamping block 43 can clamp the redundant film on the first gear 20 and the cut raw paper 21 corner parts, meanwhile, the tympanic membrane 35 returns to the original position under the action of the fifth spring 52, the space in the joint pipe 36 is increased, the adhesive in the storage tank 46 enters the joint pipe 36 from the second one-way valve 48 and the second connecting pipe 47, when the sliding rod 33 moves to the position of the bulge 38, the adhesive is ejected by the bulge 38, so that the sliding rod 33 pushes out the redundant films clamped by the clamping blocks 43 and the cut leftover materials of the raw material paper 21 to be ejected into the first placing frame 6, and finally, the food wrapping paper after film covering is finished is put into the second placing frame 8.

The points to be finally explained are: first, in the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounted," "connected," and "connected" should be understood broadly, and may be a mechanical connection or an electrical connection, or a communication between two elements, and may be a direct connection, and "upper," "lower," "left," and "right" are only used to indicate a relative positional relationship, and when the absolute position of the object to be described is changed, the relative positional relationship may be changed;

secondly, the method comprises the following steps: in the drawings of the disclosed embodiments of the invention, only the structures related to the disclosed embodiments are referred to, other structures can refer to common designs, and the same embodiment and different embodiments of the invention can be combined with each other without conflict;

and finally: the above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention are intended to be included in the scope of the present invention.
