[0034] Figure 1 The figure schematically shows the state structure diagram of the processing equipment 100 according to the embodiment of the present utility model. Figure 2 for Figure 1 Schematic diagram of the structure of the first extrusion part 10 of the processing equipment 100. Figure 3 for Figure 1 A structural diagram of the first extrusion member 10 of the processing equipment 100 from another perspective. Figure 1 、 2As shown in Figures 3 and 4, the present invention proposes a processing device 100. The processing device 100 in the present invention includes a first extrusion member 10 and a second extrusion member 20. The second extrusion member 20 is arranged on one side of the first extrusion member 10 in the thickness direction, and the first extrusion member 10 and the second extrusion member 20 are capable of relative movement. The first extrusion member 10 has a plurality of first protrusion structures 11 spaced apart along a first direction on the side facing the second extrusion member 20, and the second extrusion member 20 has a plurality of second protrusion structures 21 spaced apart along the first direction on the side facing the first extrusion member 10. Along the first direction, the plurality of first protrusion structures 11 and the plurality of second protrusion structures 21 are staggered and configured to extrude a first corrugated paper layer. A first tube body 12 is arranged between adjacent first protrusion structures 11. The first tube body 12 is used to store adhesive, and the first tube body 12 has a first outlet end on the side facing the second protrusion structures 21. The first direction is perpendicular to the arrangement direction of the first extrusion member 10 and the second extrusion member 20.

[0035] According to the technical solution of the present invention, the operator can place the first corrugated paper layer between the first extrusion member 10 and the second extrusion member 20. As the first extrusion member 10 and the second extrusion member 20 move toward each other, and due to the multiple first protrusion structures 11 on the first extrusion member 10 and the multiple second protrusion structures 21 on the second extrusion member 20, the first corrugated paper layer can be extruded into a wavy structure, and the first tube body 12 located between adjacent first protrusion structures 11 is used to store adhesive, and can be coated with adhesive on one side of the wavy first corrugated paper layer through the first outlet end, which is convenient for bonding flat paper on one side of the wavy first corrugated paper layer, and then protecting one side of the first corrugated paper layer. The processing equipment 100 of the present invention can extrude and form the first corrugated paper layer respectively through the first extrusion member 10 and the second extrusion member 20, and can also coat one side of the corrugated paper with adhesive through the first tube body 12, which is convenient for subsequent bonding of the first corrugated paper layer, thereby improving the manufacturing efficiency of the overall corrugated cardboard.

[0036] Specifically, in this embodiment, the corrugated paperboard includes a first plane paper, a first corrugated paper layer, a second plane paper layer, a second corrugated paper layer and a third plane paper layer, which are bonded in sequence.

[0037] Specifically, in this embodiment, the first protruding structure 11 and the second protruding structure 21 are respectively strip-shaped structures, and respectively extend along the second direction.

[0038] In some embodiments of the present invention, the first extrusion member 10 has a first channel therein, the first tube body 12 has a first inlet end, one end of the first channel is connected to the first inlet end, and the other end of the first channel is connected to the outside. In this embodiment, the first channel is connected to the first tube body 12, and the adhesive can enter through the other end of the first channel and enter the first tube body 12 through one end of the first channel. The flow of the adhesive can fill the first channel and the first tube body 12 through external extrusion. After the first extrusion member 10 and the second extrusion member 20 extrude the corrugated paper into shape, an operator or other automatic device pushes the adhesive in the first channel, thereby causing the adhesive in the first tube body 12 connected to the first channel to be discharged through the first outlet end and then coated on the corrugated paper, facilitating the subsequent bonding operation of flat paper.

[0039] Specifically, in this embodiment, a plurality of first outlet ends are provided, and the plurality of first outlet ends are spaced apart along the second direction, so that the corrugated paper can be coated at a plurality of positions along the second direction, thereby improving the stability of the corrugated paper and the flat paper.

[0040] In some embodiments of the present invention, Figure 1 、 4 As shown in Figure 6, the processing equipment 100 also includes a third extrusion member 30, which is disposed on a side of the second extrusion member 20 facing away from the first extrusion member 10, and the third extrusion member 30 and the second extrusion member 20 are capable of relative movement. The side of the second extrusion member 20 facing the third extrusion member 30 has a plurality of third protrusion structures 23 spaced apart along the second direction, and the side of the third extrusion member 30 facing the second extrusion member 20 has a plurality of fourth protrusion structures 31 spaced apart along the second direction. The plurality of third protrusion structures 23 and the plurality of fourth protrusion structures 31 are staggered along the second direction and configured to extrude a second corrugated paper layer, with the first and second directions intersecting. In this embodiment, the first corrugated paper can be extruded between the third extrusion member 30 and the second extrusion member 20, and the second corrugated paper can be extruded between the first extrusion member 10 and the second extrusion member 20. This allows the processing equipment 100 to extrude multiple corrugated paper sheets, thereby improving the efficiency of corrugated paper manufacturing.

[0041] In addition, if Figure 4 and 5As shown, the arrangement direction of the plurality of third protrusion structures 23 and the arrangement direction of the plurality of second protrusion structures 21 are arranged perpendicularly, indicating that the force direction of the corrugated paper extruded by the first extrusion member 10 and the second extrusion member 20 is perpendicular to the force direction of the corrugated paper extruded by the second extrusion member 20 and the third extrusion member 30. This embodiment can combine corrugated paper with two corrugated directions arranged perpendicularly to form a new corrugated paperboard structure, and at the same time can increase the dual pressure resistance of the corrugated paperboard, and can have pressure resistance in both directions.

[0042] Specifically, in this embodiment, the third protruding structure 23 and the fourth protruding structure 31 are respectively strip-shaped structures, and respectively extend along the first direction.

[0043] In some embodiments of the present invention, a second tube 22 is disposed between adjacent second protrusions 21. The second tube 22 is used to store adhesive, and the second tube 22 has a second outlet on the side facing the first protrusion 11. In this embodiment, the second tube 22 is used to store adhesive, and adhesive can be applied to the other side of the corrugated paper through the second outlet, facilitating bonding of flat paper to the other side of the corrugated paper. Combined with the first tube 12, this allows bonding and protection of opposite sides of the corrugated paper, thereby achieving a structure with both single-layer corrugated paper and double-layer flat paper.

The third tube 24 is used to store adhesive, and a third outlet is provided on the side of the third tube 24 facing the fourth protrusion 31. In this embodiment, the third tube 24 is used to store adhesive. The third outlet allows adhesive to be applied to one side of the corrugated paper between the second extrusion member 20 and the third extrusion member 30. This facilitates bonding of flat paper to one side of the extruded corrugated paper. This bonding and protection of one side of the corrugated paper facilitates subsequent processing of the entire corrugated board.

[0045] In some embodiments of the present invention, the second extrusion member 20 has a second channel, the second tube 22 has a second inlet end, and the third tube 24 has a third inlet end. The first end of the second channel is connected to the second inlet end, the second end of the second channel is connected to the third inlet end, and the third end of the second channel is connected to the outside. In this embodiment, the second channel is connected to the second tube 22 and the third tube 24, respectively. Adhesive can enter through the third end of the second channel, enter the second tube 22 through the second end of the second channel, and enter the third tube 24 through the third end of the second channel. The flow of adhesive can be used to fill the second channel, the second tube 22, and the third tube 24 through external extrusion. After the first extrusion member 10 and the second extrusion member 20 have extruded the corrugated paper, an operator or other automatic device pushes the adhesive in the second channel, causing the adhesive in the second tube 22 connected to the second channel to be discharged through the second outlet end and then applied to the corrugated paper, facilitating the subsequent bonding of flat paper.

[0046] Specifically, after the third extrusion member 30 and the second extrusion member 20 extrude the corrugated paper into shape, the operator or other automatic device pushes the adhesive in the second channel, so that the adhesive in the third tube body 24 connected to the second channel is discharged through the third outlet end and then coated on the corrugated paper, facilitating the subsequent bonding operation of the flat paper.

[0047] Specifically, in this embodiment, multiple second outlet ends are provided, and the multiple second outlet ends are spaced apart along the second direction, which can coat the corrugated paper between the first extrusion member 10 and the second extrusion member 20 at multiple positions along the second direction, thereby improving the stability of the corrugated paper and the flat paper.

[0048] Specifically, in this embodiment, a plurality of third outlet ends are provided, and the plurality of third outlet ends are spaced apart along the first direction, so as to be able to coat the corrugated paper between the second extrusion member 20 and the third extrusion member 30 at multiple positions along the first direction, thereby improving the stability of the corrugated paper and the flat paper.

[0049] In some embodiments of the present invention, Figure 6 As shown, a fourth tube 32 is disposed between adjacent fourth protrusions 31. The fourth tube 32 is used to store adhesive, and a fourth outlet is provided on the side of the fourth tube 32 facing the third protrusion 23. In this embodiment, the fourth tube 32 is used to store adhesive, and adhesive can be applied to the other side of the corrugated paper through the fourth outlet, facilitating bonding of flat paper to the other side of the corrugated paper. In conjunction with the third tube 24, opposing sides of the corrugated paper can be bonded and protected, thereby achieving a structure of corrugated paperboard with both single-layer corrugated paper and double-layer flat paper.

[0050] In some embodiments of the present invention, the third extrusion member 30 has a third channel therein, the fourth tube 32 has a fourth inlet end, one end of the third channel is connected to the fourth inlet end, and the other end of the third channel is connected to the outside world. In this embodiment, the third channel is connected to the fourth tube 32, and adhesive can enter through the other end of the third channel and enter the fourth tube 32 through one end of the third channel. The flow of adhesive can fill the third channel and the fourth tube 32 through external extrusion. After the third extrusion member 30 and the second extrusion member 20 extrude the corrugated paper into shape, an operator or other automatic device pushes the adhesive in the third channel, causing the adhesive in the fourth tube 32 connected to the third channel to be discharged through the fourth outlet end and then coated on the corrugated paper, facilitating the subsequent bonding operation of flat paper.

[0051] In some embodiments of the present invention, Figure 1 and 4 As shown, the first extrusion member 10 is provided with support members 13 on opposite sides along the first direction. The support members 13 are provided with sliding grooves 131, and the sliding grooves 131 extend along the third direction. The second extrusion member 20 is provided with first sliding members 25 on opposite sides along the first direction. The first sliding members 25 are arranged in the sliding grooves 131 so as to be movable along the third direction. The third direction is parallel to the arrangement direction of the first extrusion member 10 and the second extrusion member 20. In this embodiment, the two support members 13 are provided on opposite sides of the first extrusion member 10 to support and fix the first extrusion member 10. The first sliding members 25 on both sides of the second extrusion member 20 are slidably arranged in the sliding grooves 131, enabling relative movement between the second extrusion member 20 and the first extrusion member 10, thereby achieving extrusion molding of corrugated paper between the first extrusion member 10 and the second extrusion member 20.

[0052] In some embodiments of the present invention, Figure 1 and 6 As shown, the third extrusion member 30 is provided with second sliding members 33 on opposite sides along the first direction. The second sliding members 33 are arranged in the sliding groove 131 so as to be movable along the third direction.

[0053] Furthermore, in this embodiment, the processing flow of the processing equipment 100 is as follows: first, a first corrugated paper is placed between the first extrusion member 10 and the second extrusion member 20, and a second corrugated paper is placed between the second extrusion member 20 and the third extrusion member 30. Then, the second extrusion member 20 and the third extrusion member 30 are controlled separately so that the second extrusion member 20 moves toward the first extrusion member 10 and the third extrusion member 30 moves toward the second extrusion member 20, until the first extrusion member 10 and the second extrusion member 20 are completely in contact with each other, and the third extrusion member 30 and the second extrusion member 20 are completely in contact with each other, thus completing the extrusion molding of the first corrugated paper and the extrusion molding of the second corrugated paper. Simultaneously, the first corrugated paper is glued on opposite sides along the third direction, and the second corrugated paper is glued on opposite sides along the third direction.

[0054] Then, the first extrusion member 10 and the second extrusion member 20 are separated, and the second extrusion member 20 and the third extrusion member 30 are separated.

In addition, the third extrusion member 30 is moved toward the second extrusion member 20, so that the third flat paper and the second corrugated paper are bonded.

[0055] Then, the first extrusion member 10 and the second extrusion member 20 are separated, and the second extrusion member 20 and the third extrusion member 30 are taken out, and the bonded first corrugated paper and the second flat paper and the bonded second corrugated paper and the third flat paper are taken out, and then the second flat paper is bonded to the side of the second corrugated paper facing away from the third flat paper, and finally the first flat paper is bonded to the side of the first corrugated paper facing away from the second flat paper, thus realizing a corrugated cardboard structure with a five-layer paper structure.

[0056] Furthermore, in this embodiment, the processing equipment 100 can extrude and form two corrugated paper structures with different corrugation directions, and realize a combined structure of three layers of flat paper and two layers of corrugated paper by adhesive.
