Description

Technical Field

[0001] This utility model specifically relates to a corrugated paper forming device and a rapid corrugated paper forming equipment, belonging to the technical field of corrugated paper processing equipment. Background Technology

[0002] Corrugated cardboard is made by laminating and bonding facing paper and corrugated paper together. Existing corrugated cardboard forming processes require gluing and pressing. For example, Chinese Patent Publication No. CN105365273A discloses a corrugated cardboard machine that controls the bonding pressure of the upper and lower pressing plates to prevent uneven pressure. However, this structure cannot achieve continuous pressure bonding of the corrugated cardboard. Another example is Chinese Patent Publication No. CN219191507U, which discloses a corrugated paper forming device and a rapid corrugated paper forming equipment. Its purpose is to solve the problem of the corrugation top not being perpendicular to the edge of the corrugated paper during forming. Although this structure can press the corrugated paper into shape, it requires a separate gluing device for gluing, and then the corrugated cardboard is extruded and formed by the main forming roller and the main extruder, resulting in generally low corrugated paper forming efficiency. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a corrugated paper forming device and a rapid corrugated paper forming equipment, which can achieve the bonding and pressing of two layers of facing paper and one layer of corrugated paper, resulting in high forming efficiency.

[0004] The corrugated paper forming device of this utility model includes a wave-shaped paper core roller pressing assembly, a bottom surface paper roller, a glue coating roller assembly, a top surface paper roller, and a counter-pressing conveying assembly arranged in sequence. The corrugated paper core roller pressing assembly includes a base, on which a first glue box is fixed. A first glue-applying roller is disposed inside the first glue box. A paper-pressing roller is mounted on the top of the output side of the first glue box via a support. A first toothed roller and a second toothed roller that mesh with each other are mounted on the first glue box via a shaft seat. The second toothed roller is attached to the outer surface of the first glue-applying roller and the paper-pressing roller. Independent motors are respectively mounted on the outside of the first toothed roller and the second toothed roller. The glue-applying roller assembly includes a support base, a screw fixed on the support base, a bottom nut screwed onto the screw, a T-shaped seat plate slidably disposed on the screw, and a top nut screwed onto the top surface of the T-shaped seat plate; a second glue box is fixed between the T-shaped seat plates, the bottom of the second glue box is integrally formed with a diameter reduction chamber, and the bottom of the diameter reduction chamber is integrally formed with a narrow-slit glue-applying nozzle; a second glue-applying roller is mounted on the bottom of the T-shaped seat plate via a bearing; the second glue-applying roller is attached to the bottom of the narrow-slit glue-applying nozzle.

[0005] During the forming process, the paper roll is placed at the input end of the corrugated paper core roller assembly. The paper roll is then guided between the first and second toothed rollers, where it is pressed into corrugated paper. Glue is applied to the bottom surface of the corrugated paper by the first glue-coating roller. Next, the bottom facing paper from the bottom facing paper roller is guided between the second toothed roller and the pressure roller, thus achieving bonding and pressing of the corrugated paper and the bottom facing paper. The integrally bonded corrugated paper and bottom facing paper move forward, passing through the glue-coating roller assembly, and the second glue-coating roller... Driven by a motor or by the friction of the corrugated paper, the adhesive in the second glue box enters the narrow-slit glue applicator through the narrow-diameter chamber. The second glue applicator roller continuously rolls to receive the adhesive, thereby applying the adhesive to the top surface of the corrugated paper. The corrugated paper, now coated with adhesive, continues to move forward. Then, the top facing paper on the top facing paper roller is introduced onto the pressure conveyor assembly. The pressure conveyor assembly bonds and presses the top facing paper and the top surface of the corrugated paper together, thus completing the bonding and pressing of the bottom facing paper, the corrugated paper, and the top facing paper into one piece.

[0006] Furthermore, the bottom facing paper roller includes two low-position U-shaped seats, on which a first paper roller is disposed; the top facing paper roller includes two high-position U-shaped seats, on which a second paper roller is disposed; a limiting rod is screwed to the top of the low-position U-shaped seats and the high-position U-shaped seats; the first paper roller wound with the bottom facing paper roll is placed into the low-position U-shaped seat and limited by the limiting rod, waiting for the bottom facing paper to be pulled and bonded to the bottom surface of the corrugated paper; the second paper roller wound with the top facing paper roll is placed into the high-position U-shaped seat and limited by the limiting rod, waiting for the top facing paper to be pulled and bonded to the top surface of the corrugated paper.

[0007] Furthermore, the pressure conveying assembly includes a support roller frame, on which a lower roller seat and an upper roller seat are slidably disposed; a limit nut is screwed onto the top and bottom surfaces of the upper roller seat respectively; a row of drive rollers is disposed on both the lower roller seat and the upper roller seat; pulleys are installed at both ends of the drive rollers, and belts are sleeved on the pulleys; a first drive motor is installed on one of the drive rollers in each row; the gap between the two rows of drive rollers can be adjusted by the limit nut; during operation, the drive rollers are driven by the first drive motor to achieve roll forming of the top surface paper and corrugated paper.

[0008] Furthermore, a row of flat plates is fixed on both the lower roller seat and the upper roller seat. The drive roller is flush with the flat plates. Through the cooperation of the flat plates and the drive roller, the top facing paper, the corrugated paper and the bottom facing paper are rolled and formed.

[0009] Furthermore, the pressing and conveying assembly includes a transmission support frame, on which a lower transmission seat and an upper transmission seat are slidably disposed; a limit nut is screwed onto the top and bottom surfaces of the upper transmission seat respectively; both the lower and upper transmission seats are provided with a transmission belt driven by a second transmission motor, and the gap between the two transmission belts can be adjusted by the limit nut, and the transmission belts are synchronously driven by the second transmission motor, so that the two transmission belts can press the top and bottom surfaces of the corrugated paper together, and convey the bonded corrugated paper forward to the next process.

[0010] A rapid corrugated paper forming device includes a corrugated paper forming apparatus, a drying apparatus, and a cutting apparatus. The drying apparatus is located at the output end of the corrugated paper forming apparatus; the cutting apparatus is located at the output end of the drying apparatus. After the corrugated paper forming apparatus completes the corrugated paper forming, the adhesive on the corrugated paper is dried by the drying apparatus, and then the paper is cut by the cutting apparatus.
