Detailed implementation manners

[0018] Embodiment 1

[0019] As Figures 1 to 3 shown, a corrugated cardboard uniform sizing device proposed by the present utility model includes a sizing table 1, a sizing tank 101 and a cleaning mechanism; a feeding roller mechanism 2 is arranged on one side of the top end of the sizing table 1; the sizing tank 101 is arranged inside the sizing table 1, a drain valve 103 communicating with the sizing tank 101 is arranged on the side wall of the sizing table 1, a sizing port 102 is opened on the top end of the sizing tank 101 and on the sizing table 1, a sizing roller 6 is rotatably connected inside the sizing tank 101, and the sizing roller 6 is driven to rotate by a motor installed on the outer wall of the sizing table 1. A support frame 3 is arranged on the top end of the sizing table 1, a pressing component 4 is installed on the support frame 3 through an electric push rod, the pressing component 4 is driven to rotate by a motor, and the pressing component 4 corresponds to the sizing roller 6; the cleaning mechanism is arranged inside the sizing tank 101, and the cleaning mechanism is composed of a driving component and a first cleaning component and a second cleaning component installed on the driving component. The first cleaning component and the second cleaning component are driven by the driving component to reciprocate inside the sizing tank 101 to clean the sizing roller 6 and the side wall and bottom end of the sizing tank 101.

[0020] Furthermore, the sizing roller 6 is composed of a rotating cylinder and rotating shafts installed at both ends of the rotating cylinder. The rotating shafts are rotatably connected to the side wall of the sizing tank 101. A plurality of groups of glue application seats 601 are evenly installed on the outer peripheral surface of the rotating cylinder. There are gaps between the plurality of groups of glue application seats 601. The sizing material can be driven by the glue application seats 601 to contact the bottom surface of the corrugated cardboard for uniform sizing. At the same time, the gaps can reduce the smearing of the sizing material, and when the corrugated cardboard is subsequently adhered to the panel, excessive sizing material will not be squeezed out.

[0021] Furthermore, the pressing component 4 is composed of a U-shaped mounting frame and a pressing roller rotatably connected thereto. The pressing roller is driven to rotate by a motor installed on the U-shaped mounting frame. The output end of the electric push rod is connected to the top end of the U-shaped mounting frame, and the pressing roller corresponds to the sizing roller 6.

[0022] In this embodiment, the corrugated paperboard is conveyed towards the pulp tank 101 by starting the feeding roller mechanism 2. The sizing roller 6 is rotated by a motor. At the same time, the U-shaped mounting frame and the pressing roller are driven downward by an electric push rod until the pressing roller can attach the corrugated paper conveyed by the feeding roller mechanism 2 to the sizing roller 6 and move. This enables the sizing material on the sizing roller 6 to come into full contact with the bottom of the corrugated paper for sizing. Moreover, the motor drives the pressing roller to rotate, which can assist in the conveyance of the corrugated paper, improve the sizing efficiency, and drive the corrugated paper to move. When the corrugated paper contacts the glue application base 601, multiple groups of glue application bases 601 drive the sizing material inside the pulp tank 101 to come into uniform contact with the bottom of the corrugated paper, thereby performing uniform sizing on it. The corrugated paper after sizing is discharged from the discharge end of the sizing table 1. After sizing is completed, the cleaning mechanism is started to dissolve and wash the excess sizing material inside the sizing roller 6 and the pulp tank 101, and the waste liquid is discharged from the pulp tank 101.

[0023] Embodiment 2

[0024] As Figure 1 、 Figure 3 and Figure 4 shown, for a corrugated paperboard uniform sizing device proposed by the present utility model, compared with Embodiment 1, the driving assembly includes a screw rod 5, a guide rod 501, and a moving seat 502; the screw rod 5 is rotatably connected to the pulp tank 101, and the screw rod 5 is driven to rotate by a motor installed on the outer wall of the sizing table 1; the guide rod 501 is installed inside the pulp tank 101, and the screw rod 5 and the guide rod 501 are symmetrically distributed on the left and right sides of the sizing roller 6; there are two groups of moving seats 502, and the two groups of moving seats 502 are respectively installed on the screw rod 5 and the guide rod 501. One group of moving seats 502 is threadedly sleeved outside the screw rod 5, and the other group of moving seats 502 is slidably sleeved outside the guide rod 501; the first cleaning assembly is installed between the opposite ends of the two groups of moving seats 502, and the second cleaning assembly is installed between the mutually remote ends of the two groups of moving seats 502.

[0025] Furthermore, the first cleaning assembly includes a first cleaning pipe 7, a first liquid inlet valve 702, and a first brush plate 701; there are two groups of first cleaning pipes 7, and the two groups of first cleaning pipes 7 are respectively installed on the corresponding moving seats 502. The first cleaning pipe 7 is arc-shaped, and multiple groups of first nozzles are installed on the first cleaning pipe 7, and the first nozzles correspond to the outer peripheral surface of the sizing roller 6; a connecting pipe 703 is connected between the bottom ends of the two groups of first cleaning pipes 7; the first liquid inlet valve 702 is arranged at the top of one group of first cleaning pipes 7, and the first liquid inlet valve 702 is connected to an external cleaning agent supply mechanism through a first hose; there are two groups of first brush plates 701, and the two groups of first brush plates 701 are respectively installed on the side walls of the corresponding first cleaning pipes 7. The first brush plate 701 is arc-shaped, and the bristles on the first brush plate 701 are in contact with the outer peripheral surface of the sizing roller 6;

[0026] Further, the second cleaning component includes a second cleaning pipe 8, a second liquid inlet valve 801, and a second brush plate 802; the second cleaning pipe 8 is installed between the other ends of two sets of moving seats 502, and multiple groups of second nozzles are evenly installed on the left and right side walls of the second cleaning pipe 8. The second cleaning pipe 8 is U-shaped; the second liquid inlet valve 801 is installed at the top of the second cleaning pipe 8, and the second liquid inlet valve 801 is connected to an external cleaning agent supply mechanism through a second hose; the second brush plate 802 is installed on the side wall of the second cleaning pipe 8, and the bristles on the second brush plate 802 are in contact with the side wall and the bottom end of the pulp tank 101.

[0027] In this embodiment, the motor drives the screw rod 5 to rotate clockwise and counterclockwise alternately. Under the limiting action of the first cleaning component and the second cleaning component, the two sets of moving seats 502 reciprocate along the screw rod 5 and the guide rod 501, thereby driving the first cleaning component to wash the sizing roller 6 and driving the second cleaning component to wash the side wall and the bottom end of the pulp tank 101. The washing waste liquid is discharged by the drain valve 103.

[0028] Connect the external cleaning agent supply mechanism to the first liquid inlet valve 702 through the first hose. The cleaning agent provided by the external cleaning agent supply mechanism can fill the two sets of first cleaning pipes 7 under the action of the connecting pipe 703. In the initial state, the two sets of first cleaning pipes 7 drive their respective first brush plates 701 to be at the middle rotating shaft of the sizing roller 6. When the sizing roller 6 rotates for sizing, the first brush plate 701 will not interfere with the rotation of the rotating cylinder in the middle of the sizing roller 6. When the sizing roller 6 needs to be cleaned, the motor drives the sizing roller 6 to rotate slowly at a constant speed, and at the same time, the driving mechanism is used to drive the two sets of moving seats 502 to reciprocate along the screw rod 5 and the guide rod 501, thereby driving multiple groups of first nozzles on the first cleaning pipe 7 to spray the cleaning agent onto the sizing roller 6. At the same time, the first brush plate 701 can brush the outer peripheral surface of the sizing roller 6. Since the bristles have a certain flexibility, the sizing roller 6 and the sizing seat 601 can be fully brushed.

[0029] Connect the external cleaning agent supply mechanism to the second liquid inlet valve 801 through the second hose to supply the cleaning agent to the second cleaning pipe 8. When the driving component drives the two sets of moving seats 502 to reciprocate along the screw rod 5 and the guide rod 501, it can also drive the second cleaning pipe 8 to reciprocate in the pulp tank 101, spray the cleaning agent into the pulp tank 101 through multiple groups of second nozzles, and at the same time, brush the inner wall of the pulp tank 101 through the second brush plate 802 to prevent the pulp from not being cleaned up and drying out, which may interfere with subsequent sizing.

[0030] The above has described in detail the embodiments of the present invention in conjunction with the drawings. However, the present invention is not limited to this. Within the knowledge scope of those skilled in the art to which the present invention pertains, various changes can be made without departing from the purpose of the present invention.
