The conveyor belt 12 is used to transport the corrugated cardboard, and the upper surface of the corrugated cardboard is cleaned by the provided cleaning component to ensure that these impurities will not have an adverse effect on the flattening effect during the flattening process. The corrugated cardboard is pressed and wrinkled by the provided leveling device. Through continuous or intermittent action, the corrugated cardboard gradually becomes flat during the transmission process, so that the corrugated cardboard can remain flat for subsequent processing.

[0020] As an implementation method in this embodiment, Figure 1 and Figure 4As shown, the cleaning assembly includes a fixing plate 20 symmetrically fixedly mounted on the upper end surface of the fixing frame 10, a driving roller 21 is rotatably connected between the two fixing plates 20, a sleeve brush 22 is adhesively sleeved on the outer wall of the driving roller 21, one end of the driving roller 21 passes through the fixing plate 20 and the end is connected to the driving assembly. During specific use, the driving roller 21 is driven to rotate by the set driving assembly, so that the sleeve brush 22 on the driving roller 21 cleans the surface of the corrugated cardboard, and the sleeve brush 22 is adhesively fixed to the driving roller 21, so the sleeve brush 22 can be easily replaced and cleaned.

[0021] As an implementation method in this embodiment, Figure 1 As shown, the driving assembly includes a first transmission wheel 30 fixedly sleeved on the outer wall of one end of the driving roller 21, and a second transmission wheel 31 is fixedly sleeved on the outer wall of the end of the driving roller 11 connected to the driving motor 13. A transmission belt 32 is sleeved between the first transmission wheel 30 and the second transmission wheel 31. The first transmission wheel 30 and the second transmission wheel 31 rotate synchronously through the transmission belt 32. During specific use, the driving motor 13 drives the driving roller 11 to rotate and drives the second transmission wheel 31 to rotate at the same time, and drives the first transmission wheel 30 to rotate synchronously through the set transmission belt 32. The first transmission wheel 30 drives the driving roller 21 to rotate. The driving motor 13 can drive two devices to work at the same time, which saves costs to a certain extent.

[0022] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, the leveling device includes a mounting plate 40 symmetrically fixed on the outer side walls of the two fixing frames 10, the upper end surfaces of the two mounting plates 40 are fixedly connected with a limit slide bar 41, the top of the limit slide bar 41 is fixedly connected with a top plate 42, the outer side of the limit slide bar 41 is slidably sleeved with a moving plate 43, a return spring 44 is arranged between the moving plate 43 and the top plate 42, both sides of the upper end surface of the moving plate 43 are fixedly connected with a top rod 45, the top of the top rod 45 is fixedly connected with a mounting frame 46, a plurality of leveling rollers 47 are arranged in an array inside the mounting frame 46, both ends of the plurality of leveling rollers 47 are rotatably connected to the inner side wall of the mounting frame 46, and the specific use process In the embodiment, the corrugated cardboard passes under a plurality of smoothing rollers 47 when being transported by the conveyor belt 12. The corrugated cardboard is flattened by the provided smoothing rollers 47. The smoothing rollers 47 move up and down following the mounting frame 46. The mounting frame 46 is lifted up and down by the elastic function of the return spring 44. When the smoothing rollers 47 are in contact with the corrugated cardboard, the smoothing rollers 47 are lifted up. Thus, the push rods 45 drive the moving plates 43 to squeeze the return springs 44. The return springs 44 are always kept in a compressed state at this time. The rebound force of the return springs 44 makes the smoothing rollers 47 always in contact with the corrugated cardboard, thereby achieving the effect of pressing and flattening.

[0023] As an implementation method in this embodiment, Figure 3 As shown, the top end of the return spring 44 is fixedly connected to the lower end surface of the top plate 42, and the bottom end of the return spring 44 is fixedly connected to the upper end surface of the movable plate 43. The return spring 44 is wound on the outer wall of the limiting slide bar 41. The winding of the return spring 44 on the limiting slide bar 41 can avoid excessive deformation of the return spring 44, and the fixing of the movable plate 43 and the return spring 44 can drive the movable plate 43 to move up and down.

[0024] Working principle: When in use, the drive motor 13 is used to drive one of the drive rollers 11 to rotate, so that the drive roller 11 drives the conveyor belt 12 to transmit, and the conveyor belt 12 is used to transport corrugated cardboard, and the upper surface of the corrugated cardboard is cleaned by the cleaning component. The drive motor 13 drives the drive roller 11 to rotate and drives the second drive wheel 31 to rotate, and drives the first drive wheel 30 to rotate synchronously through the drive belt 32. The first drive wheel 30 drives the drive roller 21 to rotate, so that the sleeve brush 22 on the drive roller 21 cleans the surface of the corrugated cardboard. The sleeve brush 22 is bonded and fixed to the drive roller 21, so the sleeve brush 22 can be easily replaced and cleaned to ensure that these impurities will not have a negative impact on the flattening effect during the flattening process. Influence, the corrugated cardboard is pressed and wrinkled by the set flattening device. When the corrugated cardboard is transported by the conveyor belt 12, it passes under multiple flattening rollers 47. The corrugated cardboard is flattened by the set flattening rollers 47. The flattening rollers 47 follow the mounting frame 46 to move up and down. The mounting frame 46 is lifted up and down by the elastic function of the reset spring 44. When the flattening roller 47 contacts the corrugated cardboard, the flattening roller 47 is lifted up, so that the push rod 45 drives the moving plate 43 to squeeze the reset spring 44. The reset spring 44 always remains in a compressed state at this time. The rebound force of the reset spring 44 makes the flattening roller 47 always contact with the corrugated cardboard. Through continuous or intermittent action, the corrugated cardboard gradually becomes flat during the transmission process, so that the corrugated cardboard can remain in a flat state for subsequent processing.

[0025] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
