[0023] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those ordinarily skilled in the art without creative work fall within the scope of the present application.

[0024] Embodiment one: please refer to Figures 1-6 The utility model provides the following technical scheme: a kind of disposable paper lunch box production membrane device, the top rear side of the body 1 is fixed with mounting plate 21, rectangular block 2 is fixedly connected on mounting plate 21, long rod 3 is fixedly installed on the side surface of rectangular block 2, outer shell 4 is sleeved on the outer surface of long rod 3, two groups of roller 5 are rotatably connected on mounting plate 21, paper shell 6 is arranged between upper roller 5 and lower roller 5, L-shaped rod 10 is installed on the rear side of mounting plate 21, motor 9 is fixedly connected on the upper surface of L-shaped rod 10, first cylinder 7 is fixedly connected on the output end of motor 9 by rotating shaft 8, second cylinder 14 is movably arranged in the oblique upper side of first cylinder 7;Conveying mechanism for controlling second cylinder 14 to move up and down and extruding excess liquid inside paper shell 6 is arranged on mounting plate 21. Conveying mechanism includes rectangular groove 11 opened in the inside of mounting plate 21, telescopic rod 12 is fixedly connected in rectangular groove 11, first spring 13 is sleeved on the outer surface of telescopic rod 12, one end of first spring 13 away from the bottom of rectangular groove 11 is fixedly connected with slide bar 15;Slide bar 15 is fixedly connected on second cylinder 14, and slide bar 15 is slidably connected in rectangular groove 11. Force shaft 19 is rotatably connected on the rear of mounting plate 21, cam 16 is sleeved on the outer surface of force shaft 19, belt pulley 17 is fixedly connected on cam 16 and rotating shaft 8, and outer sleeve of upper and lower belt pulley 17 is connected with belt 18.

[0025] When the staff starts to spray the disposable paper lunch box, first put the paper shell 6 between the two rollers 5, so that the nozzle on the paper shell 6 spray work, start the motor 9, the output shaft 8 fixed on the motor 9 starts to rotate, the output shaft 8 rotating drive the first cylinder 7 starts to rotate, because the belt 18 through the belt pulley 17 set in the stress shaft 19 and the output shaft 8, so the output shaft 8 rotation also drive the stress shaft 19 rotation, make the sleeve set in the stress shaft 19 on the cam 16 synchronous rotation. When the cam 16 rotates to the slide bar 15 contact, the slide bar 15 force in the rectangular groove 11 inside down, the slide bar 15 drive the second cylinder 14 together down, the first spring 13 is extruded shrinkage at this time, when the cam 16 is not with the slide bar 15 contact, at this time the force of the first spring 13 disappears, the first spring 13 with the slide bar 15 and the second cylinder 14 reset. Through the second cylinder 14 and the slide bar 15 up and down sliding, change the motion trajectory of the paper shell 6, increase the friction with the paper shell 6, can effectively remove the excess liquid on the surface of the paper shell 6 after the spray, solve the coating may be uneven thickness, resulting in some area coating too thick or too thin problem.

[0026] Example two: on the basis of example one, also disclosed the power mechanism, its specific structure is as follows: the side surface of the cam 16 is provided with the power mechanism that can let the shell 4 slide left and right on the long rod 3, so that the paper shell 6 spray is more uniform.
