Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, and in particular to a spray flattening device for corrugated paper. Background Technology

[0002] Corrugated paper is made by stacking and bonding a face layer, a bottom layer, and a core layer together. Existing bonding equipment uses an automatic feeding device to release the face layer, bottom layer, and core layer during the bonding process, and then uses gluing equipment and rolling equipment to bond the three layers together. Corrugated paper can be used for food or digital product packaging; it is relatively environmentally friendly and widely used. After bonding, the corrugated paper needs to be flattened.

[0003] A search revealed a public disclosure (announcement) number: CN108909050A, which discloses a spray-flattening device for corrugated paper. The device includes a base, a front conveyor belt, a spraying device, a flattening device, and a rear conveyor belt. A flattening frame is located on the right side of the front conveyor belt, and the spraying device is located on the upper left side of the flattening frame. The spraying device has several nozzles, each with a solenoid valve at its lower middle end and a sensor at its lower left end. A controller is located on the front side of the flattening frame, and the flattening device is mounted on the flattening frame. A odor dispersing seat is located below the rear conveyor belt, and a purification box is mounted on the odor dispersing seat. This invention provides a spray-flattening device for corrugated paper that can effectively spray the corrugated paper before flattening. It is suitable for flattening corrugated paper of different thicknesses and can purify harmful substances such as formaldehyde released from the corrugated paper, improving the working environment index.

[0004] While the above-mentioned solution can effectively spray the corrugated paper before flattening, making it suitable for flattening corrugated paper of different thicknesses and purifying harmful substances such as formaldehyde released by the corrugated paper, thus improving the working environment index, it is inconvenient to limit the conveying of corrugated paper of different widths. This can lead to incomplete flattening when the corrugated paper is misaligned. Therefore, we propose a spray flattening device for corrugated paper. Utility Model Content

[0005] The main purpose of this utility model is to provide a spray flattening device for corrugated paper. By setting up a correction unit and a flattening unit, it solves the problem that it is inconvenient to limit the conveying of corrugated paper of different widths, which leads to the inability to achieve a complete flattening operation when the corrugated paper is conveyed off-center.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A spray flattening device for corrugated paper includes a conveying unit, a correction unit and a spraying unit disposed above the conveying unit, a flattening unit disposed on the side of the conveying unit, and a cleaning unit disposed inside the conveying unit.

[0008] The correction unit includes an L-shaped fixed base installed on the side wall of the conveying unit, an electric telescopic rod installed on the inner side wall of the L-shaped fixed base, and a correction component disposed at the end of the electric telescopic rod.

[0009] The flattening unit includes a fixed frame installed at the end of the conveying unit, two hydraulic telescopic rods installed on the top wall inside the fixed frame, a fixed block installed at the telescopic end of the hydraulic telescopic rods, a secondary pressure roller movably installed between the two fixed blocks, a main pressure roller movably disposed inside the fixed frame and located below the secondary pressure roller, and a second drive motor installed at the input end of the main pressure roller.

[0010] Preferably, the conveying unit includes a U-shaped base, a conveyor belt movably installed inside the U-shaped base, and a first drive motor installed at the input end of the conveyor belt.

[0011] Preferably, the correction component includes a connecting seat installed at the telescopic end of the electric telescopic pole, a connecting spring installed on the inner side wall of the connecting seat, an inclined plate installed at the end of the connecting spring, a U-shaped block installed on the inner side wall of the inclined plate, and a sliding wheel movably installed inside the U-shaped block.

[0012] Preferably, there are two sets of the correction unit, and the two sets of correction units are symmetrically arranged about the conveyor belt.

[0013] Preferably, the spray unit includes a spray box mounted on top of the U-shaped base, a nozzle mounted on the bottom of the spray box, a sealing hole opened on top of the spray box, and a sealing plug installed in the sealing hole.

[0014] Preferably, the cleaning unit includes a rotating shaft movably disposed inside the U-shaped seat and located below the conveyor belt, a cleaning roller mounted on the side wall of the rotating shaft, and a third drive motor mounted on the input end of the rotating shaft.

[0015] Preferably, a conveying unit is also provided on the other side of the flattening unit, and a purification box for absorbing harmful gases is provided above the conveying unit. This structure is a conventional technical means in this field and will not be described in detail in the figure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, through the setting of a correction unit and a flattening unit, when it is necessary to transport corrugated paper of different widths, the extension and retraction of the electric telescopic rod can make the closest distance between the two inclined plates equal to the width of the corrugated paper. At this time, when the corrugated paper is placed on the conveyor belt for transport, the sliding wheel can center the transport of the corrugated paper and perform correction transport, ensuring that the corrugated paper is located in the middle of the conveyor belt during transport and avoiding deviation. When the corrugated paper is transported to the bottom of the spray box, the nozzle can spray the liquid in the spray box to spray the corrugated paper. Then it continues to be transported to the next stage, and the second drive motor drives the main pressure roller to rotate, which works with the secondary pressure roller to flatten the corrugated paper, thereby realizing the spray flattening work of corrugated paper processing.
