Description

Technical Field

[0001] This utility model relates to the field of honeycomb paperboard processing, specifically to a honeycomb paperboard processing equipment and a honeycomb paperboard dehumidification system. Background Technology

[0002] The upper and lower surfaces of the honeycomb paper core are covered with face paper to form a honeycomb paperboard. Because both sides of the honeycomb paper core are laminated with face paper, the moisture trapped between the two face papers is difficult to drain during drying, requiring a longer drying time and resulting in low dehumidification efficiency. In addition, the honeycomb paperboard has a high moisture content, and the adhesion between the honeycomb paper core and the face paper is not strong, making it easy to delaminate.

[0003] To improve the dehumidification efficiency of honeycomb paperboard, the applicant has proposed solutions such as perforating the paper core and slotting the honeycomb paper core, making the honeycomb cells interconnected so that moisture can be discharged through the perforations and slots, thus improving the dehumidification effect of the honeycomb paperboard. See publication numbers CN203579773U and CN202862269U for examples. However, slotting the honeycomb paper core generates a large amount of dust, affecting the workshop environment and also impacting the lamination of the paper core and face paper. Perforating the paper core, on the other hand, leads to clogged vents, poor venting, and can damage the strength of the paper core. Therefore, the existing honeycomb paperboard dehumidification system needs further improvement. Utility Model Content

[0004] In view of the technical problems existing in the background art, the technical problem to be solved by this utility model is to provide a honeycomb paperboard processing equipment and honeycomb paperboard dehumidification system with good dehumidification effect and suitable for production.

[0006] This invention utilizes a circular cutter to cut the face paper during the face paper conveying process, creating intermittent cuts on the face paper without affecting the continuous conveying of the face paper. During the lamination and drying of the face paper and honeycomb paper core, moisture within the honeycomb paper core, held by the face paper, is rapidly discharged through the cuts, significantly accelerating the dehumidification speed and improving the dehumidification efficiency of the honeycomb paperboard. Simultaneously, the face paper is supported by the honeycomb paper core, and the intermittent cuts do not damage the strength of the honeycomb paperboard. Furthermore, the dust generated by face paper cutting is relatively small compared to slotting, and will not affect the production workshop or the lamination of the paper core and face paper. Improved dehumidification effect enhances the lamination quality of the honeycomb paper core and face paper.

[0007] Preferably, the paper cutting device further includes a cutting protection disc, which is disposed on both sides of the circular cutter and coaxially connected to the circular cutter. The outer diameters of the cutting protection disc and the circular cutter are similar, and the outer diameter of the circular cutter is no larger than the outer diameter of the cutting protection disc. The circumferential surface of the cutting protection disc has several axially penetrating grooves, which are evenly distributed circumferentially. The circular cutter cuts the paper through the grooves, and the cutting protection disc can limit the cutting depth of the circular cutter, thus protecting the circular cutter.

[0009] Preferably, the circular cutter makes transverse cuts, forming longitudinally intermittently arranged transverse blades on the face paper; The circular cutter is a disc-shaped toothed cutter, which has several tooth tips that are evenly distributed along the circumference. The tooth tips of the toothed cutter have a width, and the groove corresponds to the tooth tips of the toothed cutter.

[0010] Preferably, the circular cutter and the cutter holder are arranged in several groups, with several cutter holders mounted on a rotating shaft. The rotating shaft is rotatably mounted on the frame, and a power component is installed on the frame to drive the cutter holders to swing. The power component drives the cutter holders to swing, so that the circular cutter is in a working position or a standby position. For example, when feeding paper, the circular cutter is in a standby position, and the distance between it and the lower support roller increases.

[0011] Preferably, the tool holder is mounted on the rotating shaft via a mounting base; The mounting base is sleeved on and locked to the rotating shaft.

[0025] The following describes the embodiments and related details and working principles of this utility model with reference to the accompanying drawings. A honeycomb paperboard processing equipment includes a honeycomb paperboard dehumidification system, which includes a face paper cutting device 1. The face paper cutting device 1 is disposed on the face paper conveying path. The face paper cutting device 1 includes a circular cutter 11 and a lower support roller 12. The circular cutter is rotatably mounted on a cutter holder 17. The lower support roller 12 is disposed below the circular cutter. The circular cutter and the lower support roller 12 engage and rotate against each other on the face paper to form intermittent cutting edges, i.e., the cutting edges are intermittently set. In the drying condition, the cutting edges are used for exhaust. Figure 5 and Figure 7 As shown, the face paper is supported by the honeycomb paper core, and the intermittent cuts on the face paper do not damage the strength of the honeycomb paperboard. Simultaneously, moisture trapped between the two face papers in the honeycomb paper core is discharged through the cuts, accelerating the drying speed of the honeycomb paperboard, improving dehumidification efficiency, and ensuring a firm bond between the honeycomb paper core and the face paper. This invention uses a circular cutter to roll-cut the face paper, achieving continuous feeding of the face paper and maintaining continuous production. Furthermore, the dust generated by face paper cutting compared to slotting is minimal and will not affect the production workshop or the lamination of the paper core and face paper. Improved dehumidification enhances the lamination quality of the honeycomb paper core and face paper.

[0026] The honeycomb paperboard dehumidification system also includes a honeycomb paperboard drying device 3, see Figure 1 The honeycomb paperboard drying device 3 includes an oven 32 and a hot plate 31 disposed in the oven 32. The honeycomb paperboard is pressed by the hot plate 31 in the oven 32, so that the face paper 4 and the honeycomb paper core 5 are firmly bonded. At the same time, the hot plate 31 quickly transfers heat energy to the honeycomb paperboard, removes the moisture from the honeycomb paperboard, and dries the honeycomb paperboard quickly.

[0027] The paper cutting device 1 further includes a cutting protection disc 16, which is disposed on both sides of the circular cutter 11 and coaxially connected to the circular cutter 11. The outer diameters of the cutting protection disc 16 and the circular cutter are similar, and the outer diameter of the circular cutter is not greater than the outer diameter of the cutting protection disc. The circumferential surface of the cutting protection disc 16 is provided with a plurality of axially penetrating grooves 161, which are evenly distributed in the circumferential direction. The circumferential surface between the grooves 161 is named the protective surface 162. The circular cutter, blocked by the cutting protection discs 16 on both sides, does not touch the paper and can cut the paper through the grooves 161. (See attached image) Figure 8 The distance from the midpoint of the line connecting the two ends of the groove 161 to the center of the cutting protection disk 16 is shorter than the radius of the cutting protection disk 16, and the distance between them is D. For the circular cutter to cut the paper, the difference in radius between the circular cutter and the cutting protection disk 16 must be within the range of D. That is, the outer diameters of the cutting protection disk 16 and the circular cutter are close, and the outer diameter of the circular cutter is not greater than the outer diameter of the cutting protection disk. In this way, the circular cutter can cut the paper through the groove 161. Taking the outer diameters of the cutting protection disk 16 and the circular cutter as the same, when the protective surface 162 of the cutting protection disk 16 is opposite to the paper, the circular cutter cannot cut the paper; when the groove 161 of the cutting protection disk 16 is opposite to the paper, the blade of the circular cutter presses against the paper to cut, thus forming an intermittent cutting edge. The cutting protection disk 16 and the circular cutter cooperate to achieve intermittent cutting, and at the same time, the cutting protection disk 16 can limit the cutting depth of the circular cutter, thus protecting the circular cutter.

[0028] The circular cutter cuts paper in two ways: longitudinal cutting and transverse cutting. These are described below through two examples: Example 1, see appendix Figure 4 and 5 The circular cutter makes longitudinal cuts, forming longitudinally intermittently arranged blades on the paper. The circular cutter 11 is a round blade with a continuous circumferential cutting edge 111. The length of the groove 161 on the cutting protection disc 16 determines the cutting length. Example 2, see appendix Figure 6 and 7 The circular cutter makes transverse cuts, forming longitudinally intermittently arranged transverse blades on the paper. The circular cutter 11 is a disc-shaped toothed blade, that is, the circumferential surface is toothed, with several tooth tips evenly distributed along the circumferential direction. The tooth tips 112 of the toothed blade have a width, and the groove 161 corresponds to the tooth tips 112 of the toothed blade. The tooth tips cut the paper through the groove 161, forming transverse blades. The width of the transverse blades is the same as the width of the tooth tips.

[0029] The circular cutter and cutter holder 17 are arranged in several groups. Several cutter holders 17 are mounted on a rotating shaft 13, which is rotatably mounted on a frame. A power component is mounted on the frame to drive the cutter holders 17 to swing. The power component drives the cutter holders 17 to swing, so that the circular cutter is in a working position or a standby position. For example, when feeding paper, the circular cutter is in a standby position, and the distance between it and the lower support roller 12 increases; when working, the circular cutter is in a working position, and the circular cutter presses against the paper. The cutter holder 17 is mounted on the rotating shaft 13 through a mounting base 18; the mounting base 18 is sleeved on the rotating shaft 13 and locked to the rotating shaft 13. The lower end of the cutter holder is rotatably connected to the mounting base, and a spring 19 is provided between the upper end of the cutter holder and the mounting base. In the figure, the power component is a cylinder 14, which is connected to a connecting rod 15, and the connecting rod is connected to a rotating shaft 13. The mounting base 18 has a mounting groove, and the tool holder 17 is L-shaped. The upright section of the tool holder enters the mounting groove, and the lower end of the upright section is rotatably connected to the mounting base 18. The upper end of the upright section has a spring 19 groove, and one end of the spring 19 is placed in the spring 19 groove. The circular cutter is rotatably mounted on the horizontal section of the tool holder 17. The cylinder drives the connecting rod to swing, causing the rotating shaft to rotate, which in turn causes the tool holder to swing.
