When the hydraulic cylinder 81 is working, the telescopic end of the hydraulic cylinder 81 can move the flattening assembly 8 up and down, so that the pressure roller 83 can easily contact and cooperate with the corrugated cardboard. At the same time, when the motor 85 is working, the output shaft of the motor 85 can drive the pressure roller 83 to rotate, thereby realizing the flattening of the corrugated cardboard.

[0024] Both sides of the lower part of the U-shaped seat 4 are equipped with pressing mechanisms 5. The pressing mechanism 5 includes a connecting plate 51, a pressing wheel 52, and a telescopic rod 53. The connecting plate 51 is fixedly installed on the front and rear sides of the U-shaped seat 4.

The pressing wheel 52 is rotatably installed inside the mounting frame 54. When the corrugated cardboard to be flattened is placed on the conveyor 2, the spring 55 can push the mounting frame 54 to drive the pressing wheel 52 to move downward, so that the pressing wheel 52 contacts the corrugated cardboard, thereby pressing the corrugated cardboard and preventing the corrugated cardboard from moving during the operation.

[0025] The flattening assembly 8 is located between the two pressing mechanisms 5. A cleaning assembly 6 is installed on the top surface of the U-shaped seat 4. The cleaning assembly 6 includes a collection box 61, a fan 62, and a collection cover 63. The collection box 61 is fixedly installed on the top surface of the U-shaped seat 4. The fan 62 is installed on one side of the top surface of the collection box 61, and an exhaust pipe 64 is fixedly installed on the other side of the top surface of the collection box 61. The collection cover 63 is located on one side of the pressure roller 83. The collection cover 63 is fixedly connected to the U-shaped rod 82 via a connecting bracket 65. The collection cover 63 is connected to the pressure roller 83 and the corrugated cardboard. Correspondingly, the collection box 61 and the collection cover 63 are connected by a retractable hose 66. The front surface of the collection box 61 is hinged to the box door 67. When the fan 62 is working, it can create a negative pressure inside the collection box 61, so that the dust and paper scraps on the pressure roller 83 and the corrugated cardboard can enter the collection box 61 through the collection cover 63 and the hose 66, thereby collecting the dust and paper scraps. The gas inside the collection box 61 is discharged through the exhaust pipe 64. Opening the box door 67 can clean the dust and paper scraps inside the collection box 61.

[0026] The collection box 61 has sliding grooves 68 on both sides inside. The front of the sliding groove 68 is open to the outside. The sliding slider 69 is slidably installed inside the sliding groove 68. The two sliders 69 are connected by a filter plate 610. The fan 62 and the collection cover 63 are corresponding to and cooperate with the filter plate 610. The filter plate 610 can filter the exhaust gas to prevent dust and paper scraps from being discharged through the exhaust pipe 64 and to prevent pollution of the working environment. By moving the slider 69 in the sliding groove 68, the filter plate 610 can be removed from the collection box 61, which makes it easy to clean or replace the filter plate 610.

[0027] The lower end of the cleaning component 6 is connected to the flattening component 8 and corresponds to the corrugated cardboard.

[0028] Working principle:

[0029] The corrugated cardboard to be flattened is placed on conveyor 2. Under the action of spring 55, the mounting frame 54 is pushed, causing the pressure roller 52 to move downward, so that the pressure roller 52 contacts the corrugated cardboard, thereby pressing the corrugated cardboard and preventing it from moving during operation. The drive motor 71 works, and the output shaft of the drive motor 71 drives the upper pulley 74 to rotate through the rotating rod 73. The upper pulley 74 drives the lower pulley 74 to rotate through the belt 75. The lower pulley 74 drives the clamping mechanism 3 to rotate, and the lower pulley 74 drives the corresponding screw sleeve 34 to rotate. The rotation of the screw sleeve 34 causes the screw 33 to move. The guide rod 35 moves along the guide hole 36 to guide the clamping plate 31. The screw 33 can drive the clamping plate 31 to move, so that the clamping plate 31 contacts the corrugated cardboard, thereby fixing the corrugated cardboard and preventing it from moving during operation, which would affect the flattening of the corrugated cardboard, thus improving the flattening effect of the corrugated cardboard. Conveyor 2 works. During operation, conveyor 2 transports corrugated cardboard, while hydraulic cylinder 81 moves vertically, allowing the pressing assembly 8 to move easily between the pressure roller 83 and the corrugated cardboard. Simultaneously, motor 85 rotates, its output shaft driving the pressure roller 83 to flatten the cardboard. Fan 62 creates negative pressure within collection box 61, allowing dust and paper scraps from the pressure roller 83 and the corrugated cardboard to pass through collection cover 63 and hose 66. The gas is placed into the collection box 61 to collect dust and paper scraps. The gas inside the collection box 61 is discharged through the exhaust pipe 64. Opening the box door 67 allows the dust and paper scraps inside the collection box 61 to be cleaned. The exhaust gas is filtered by the filter plate 610 to prevent dust and paper scraps from being discharged through the exhaust pipe 64 and to prevent pollution of the working environment. The filter plate 610 can be removed from the collection box 61 by moving the slider 69 in the slide groove 68, which makes it easy to clean or replace the filter plate 610.
