DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 3 , the utility model provides a technical solution:

[0019] A corrugated paper double-sided machine comprises a base 1 and a conveying mechanism and a drying component installed above the base 1, the conveying mechanism comprises a support frame 1 2 and a support frame 2 3 symmetrically installed on the base 1, and a conveyor belt 4 installed between the support frame 1 2 and the support frame 2 3, a conveying roller 5 and a coating roller 6 are installed on the support frame 1 2 in sequence, a pressing roller 7 is installed on one side, a storage box 8 is provided on the top, a storage box 9 connected to the storage box 8 through a pipeline is installed below the coating roller 6, a solenoid valve is installed on the pipeline, slide grooves are provided on both sides of the inner wall of the storage box 9, a limit block 10 is slidably installed inside the slide groove, a float 11 is installed on one side of the limit block 10, a cavity is provided in the storage box 9, and a control component connected to the float 11 is installed inside the cavity.

[0020] During operation, the facial paper passes between the conveying roller 5 and the smearing roller 6, and is conveyed by the conveying roller 5. The smearing roller 6 rotates to dip the adhesive inside the storage box 9 and adhere it to the surface of the facial paper. The smeared facial paper continues to be conveyed forward, and is pressed by the pressing roller 7, so that the facial paper and the corrugated cardboard on the conveyor belt 4 are bonded together. The corrugated paper bonded with the facial paper is conveyed into the drying component through the conveyor belt 4 for heating and fixing, so that the corrugated paper is produced and formed. After working for a period of time, as the adhesive content in the storage box 9 decreases, the float 11 is set to detect the adhesive content in the storage box 9, and the storage box 8 automatically adds adhesive to the storage box 9 through the control component.

[0021] The drying assembly includes a U-shaped frame installed above the base, a hot air blower installed on the top of the U-shaped frame, a screw 12 threadedly connected to the top of the U-shaped frame, a fixed block arranged at one end of the screw 12, and hot air plates 1 and 2 installed on the fixed plates in sequence and connected to the hot air blower. The screw runs through the U-shaped frame and is connected to the fixed block.

[0022] A plurality of hot air nozzles are arranged under the hot air plate 1 and the hot air plate 2.

[0023] The hot air is generated by the hot air blower and transmitted to the hot air plate 1 and the hot air plate 2, and is sprayed out through the hot air nozzle to achieve the purpose of double-sided drying, thereby improving the drying effect. When in use, the distance between the hot air plate 1 and the hot air plate 2 and the facial paper and the corrugated paper can be adjusted by rotating the screw 12 according to the thickness between the facial paper and the corrugated paper, thereby improving applicability.

[0024] The control assembly includes a touch switch respectively installed on the top wall and the bottom wall of the cavity, a touch plate matching the touch switch, and a pull rope 14 whose two ends are respectively connected to the touch plate 13 and the float 11, and the touch switch is electrically connected to the solenoid valve.

[0025] A guide roller is installed above the material storage box 9, and the pull rope 14 passes around the guide roller.

[0026] During operation, as the adhesive content inside the storage box 9 decreases, the float 11 and the limit block 10 will move downward, thereby pulling the pull rope 14 to drive the touch plate 13 to move upward. When it contacts the touch switch located on the top wall of the cavity, the adhesive content inside the storage box 9 reaches the minimum, the touch switch on the top wall is squeezed, and the solenoid valve power switch is turned on to automatically add adhesive to the storage box 9. Similarly, when adding, the float 11 will move upward, driving the touch plate 13 to move downward until it contacts the touch switch on the bottom wall, and then the solenoid valve power switch is closed to stop filling.
