Figure 4 and Figure 5 As shown, the purpose of such arrangement is to facilitate shaping of the wavy core paper interlayer inside the corrugated board;

[0023] A heating chamber is provided inside the compaction drying plate 4 and the arc-shaped shaping drying plate 10, and a heater is fixedly connected to the inner side wall of the heating chamber. The distance between two adjacent arc-shaped shaping drying plates 10 on the same side is the same. Two rotating shafts 11 are rotatably connected between the multiple support columns 2 and the inner side wall of the return plate 5. The two rotating shafts 11 on the same side are connected by a chain 12. The outer side walls of the two rotating shafts 11 on the same side are sleeved with chain plates adapted to the chain 12.

[0024] Two sliding openings are provided at the bottom of the processing frame 1, and a vertical rack 13 is slidably connected to the inner wall of the sliding opening. A gear 14 is fixedly sleeved on the outer wall of the rotating shaft 11. The transverse rack 6 and the vertical rack 13 are meshed and connected with the gear 14. The tops of the two vertical racks 13 are fixedly connected to the same lifting plate 15. The piston end of the cylinder 3 located below penetrates the lifting plate 15 and a through hole is provided on the top of the lifting plate 15. The bottom of the processing frame 1 and the bottom of the lifting plate 15 are connected by a second spring 16, and the second spring 16 is sleeved on the piston end of the cylinder 3 located below.

[0025] The functional principle of the utility model can be explained through the following operation mode: when the device is used to press corrugated paperboard, hot melt adhesive is applied to the original paperboard used to make the corrugated paperboard in advance, and the hot melt adhesive can be melted after being heated. At this time, the original paperboard to be pressed is respectively located on the top of the two arc-shaped shaping drying plates 10 and above the compacting drying plate 4 located below;

[0026] The initial state of the device is Figure 1 As shown, the piston ends of the two cylinders 3 are started to extend, and the piston ends of the cylinders 3 drive the compaction and drying plates 4 to extend, and the compaction and drying plates 4 located above will drive the arc-shaped shaping drying plates 10 located above to move downward;

[0027] When the arc-shaped drying plate 10 is driven to move downward, the movable plate 8 is also driven to move downward, so that the first spring 9 is compressed. At the same time, the compacting drying plate 4 located below drives the arc-shaped drying plate 10 located below to move upward, and also drives the movable plate 8 to move upward and compress the first spring 9 until the device is as shown in FIG. Figure 2 As shown, multiple original paperboards are also made from Figure 4 Arrival Figure 5 The position shown in the figure is shown, the cylinder 3 is closed, and the heater inside the compaction drying plate 4 and the arc-shaped shaping drying plate 10 is started at this time. The heater will heat the compaction drying plate 4 and the arc-shaped shaping drying plate 10, so that the hot melt adhesive on the original paperboard is melted, and the melted hot melt adhesive is adhered to the adjacent original paperboards, so that the original paperboard in the middle is wavy, and the corrugated paperboard can be formed;

[0028] When the corrugated cardboard is formed, the piston end of the cylinder 3 is started to contract, and the piston ends of the two cylinders 3 will drive the two compacting drying plates 4 to move upward and downward. At this time, the compacted and formed corrugated cardboard will remain on two rows of multiple arc-shaped drying plates 10;

[0029] At this time, the compacting and drying plate 4 located below will also drive the lifting plate 15 to move downward. The downward movement of the lifting plate 15 will compress the second spring 16. At the same time, the lifting plate 15 will drive the vertical rack 13 to move downward, and the vertical rack 13 will mesh with the gear 14. The two adjacent rotating shafts 11 are transmitted through the chain 12, so that the rotating shaft 11 located above drives the gear 14 to mesh with the horizontal rack 6, so that the horizontal rack 6 drives the arc-shaped shaping drying plate 10 to move in the direction away from the formed corrugated cardboard, so that multiple arc-shaped shaping drying plates 10 are pulled out from the formed corrugated cardboard. When the arc-shaped shaping drying plates 10 are pulled out from the formed corrugated cardboard, they will fall on the compacting and drying plate 4 located below, close the cylinder 3, let the worker take down the formed corrugated cardboard, start the cylinder 3 piston end to extend, the second spring 16 extends, and the lifting plate 15 moves upward, so that the horizontal rack 6 moves toward the compacting and drying plate 4 until the state of the device returns to as Figure 1 As shown in FIG. 1 , the original paperboard to be pressed is respectively placed on the top of the two arc-shaped shaping drying plates 10 and on the top of the compacting drying plate 4 located below. The entire pressed corrugated paperboard is as shown in FIG. Figure 1 As shown, corrugated cardboard can be produced by repeating the above process.
