[0043] Reference Figure 4 and Figure 5 When the corrugated paper is pushed onto the cutting table 3, the piston rod of the driving cylinder 13 extends out, driving the mounting plate 14 and the pressing plate 16 to move downward; when the pressing plate 16 contacts the corrugated paper, the piston rod of the driving cylinder 13 continues to extend a set distance, so that the connecting spring 17 is compressed, so that the pressing plate 16 elastically presses against the corrugated paper under the action of the elastic force of the connecting spring 17 itself, which helps to improve the stability of the corrugated paper during the cutting process, thereby helping to ensure the cutting effect of the corrugated paper.

[0044] Reference Figure 4When the corrugated paper is elastically pressed, the piston rod of the hydraulic cylinder 51 extends, driving the cutting blade 52 to move toward the corrugated paper and correspondingly insert into the inserting blade seat 53, thereby cutting the corrugated paper.

[0046] Reference Figure 6 and Figure 7 The driving assembly 10 includes an electric push rod 101, a connecting member 102, a first connecting rod 103 and a second connecting rod 104. The electric push rod 101 is fixedly mounted on the side wall of the cutting table 3, the first connecting rod 103 is rotatably mounted on the side wall of the cutting table 3, one end of the second connecting rod 104 is hinged to the connecting rod 9, and the other end of the second connecting rod 104 is hinged to the first connecting rod 103. In this embodiment, the connecting member 102 includes a first connecting portion 1021 and a second connecting portion 1022. The cross-section of the first connecting portion 1021 is T-shaped, and a T-shaped clamping groove 11 is provided on the second connecting portion 1022. The first connecting portion 1021 is fixedly connected to the output end of the electric push rod 101, and the second connecting portion 1022 is hinged to one end of the first connecting rod 103 away from the second connecting rod 104. The first connecting portion 1021 is slidably clamped in the clamping groove 11.

[0047] Reference Figure 6 and Figure 7When adjusting the cutting angle of corrugated paper, the electric push rod 101 is started, and the output end of the electric push rod 101 drives the first connecting part 1021 to move linearly, so that the second connecting part 1022 slides along the length direction of the first connecting part 1021, thereby driving the first connecting rod 103, the second connecting rod 104 and the connecting rod 9 to rotate. When the connecting rod 9 rotates, it drives the mounting frame 4 and the inserting knife seat 53 to rotate synchronously at the same angle, that is, it drives the cutting blade 52 and the inserting knife seat 53 to rotate synchronously at the same angle, which helps to achieve automatic adjustment of the cutting angle of corrugated paper, thereby helping to ensure the cutting effect of corrugated paper of different specifications.

[0048] Reference Figure 1 A placement slot 29 is provided on the cutting table 3, and the placement slot 29 is located on the side of the mounting frame 4 away from the placement frame 12, and a material storage box 30 is placed inside the placement slot 29.

[0049] Reference Figure 1 After the corrugated paper is cut, the plurality of conveying rollers 31 drive the cut corrugated paper to move toward the storage box 30, so that the cut corrugated paper moves and falls into the storage box 30, and then the cut corrugated paper is collected and stored.

[0050] The implementation principle of the embodiment of the present application is as follows: when the corrugated paper is conveyed to the feeding table 2 through the conveying frame 1, the output shaft of the linear drive 18 extends out, driving the anti-slip plate 21 to resist and push the adjusting block 242, so that the adjusting block 242 moves along the guide rod 243 and the supporting spring 244 contracts, so that the contact position between the bottom end of the adjusting rod 241 and the adjusting curved surface 25 gradually moves upward with the movement of the adjusting block 242, and then the adjusting rod 241 drives the second clamping plate 23 to gradually move upward, which helps the second clamping plate 23 to cooperate with the first clamping plate 22 to clamp the side of the corrugated paper on the feeding table 2.

[0051] After the first clamping plate 22 and the second clamping plate 23 clamp the corrugated paper, the supporting spring 244 cannot continue to contract, and the output shaft of the linear drive 18 continues to extend, thereby pushing the adjustment block 242 to drive the mounting box 20 to move synchronously, and then drive the first clamping plate 22, the second clamping plate 23 and the clamped corrugated paper to move toward the cutting table 3 together, which helps to push the corrugated paper onto the cutting table 3 according to the set distance.

[0052] When the corrugated paper is pushed onto the cutting table 3, the piston rod of the driving cylinder 13 extends out, driving the mounting plate 14 and the pressure plate 16 to move downward; when the pressure plate 16 contacts the corrugated paper, the piston rod of the driving cylinder 13 continues to extend a set distance, so that the connecting spring 17 is compressed, so that the pressure plate 16 elastically presses against the corrugated paper under the action of the elastic force of the connecting spring 17 itself, which helps to improve the stability of the corrugated paper during the cutting process, thereby helping to ensure the cutting effect of the corrugated paper.

[0053] When the corrugated paper is elastically pressed, the piston rod of the hydraulic cylinder 51 extends, driving the cutting blade 52 to move toward the corrugated paper and correspondingly insert into the inserting blade seat 53, thereby cutting the corrugated paper. The inserting blade seat 53 helps to improve the stability of the cutting blade 52 during the cutting process of the corrugated paper, thereby helping to improve the accuracy of the cutting position of the corrugated paper by the cutting blade 52. The guide rod 26 helps to play a guiding role in the movement of the cutting blade 52, thereby helping to further improve the stability of the cutting blade 52 during use, and further helping to improve the cutting effect of the cutting blade 52 on the corrugated paper. The limit plate 27 helps to limit the moving range of the cutting blade 52, and the reset spring 28 helps to cooperate with the hydraulic cylinder 51 to reset the cutting blade 52.

[0054] When the cutting angle of the corrugated paper is adjusted, the electric push rod 101 is started, and the output end of the electric push rod 101 drives the first connecting part 1021 to move linearly, so that the second connecting part 1022 slides along the length direction of the first connecting part 1021, thereby driving the first connecting rod 103, the second connecting rod 104 and the connecting rod 9 to rotate. When the connecting rod 9 rotates, it drives the mounting frame 4 and the inserting knife seat 53 to rotate synchronously at the same angle, that is, it drives the cutting blade 52 and the inserting knife seat 53 to rotate synchronously at the same angle, which helps to achieve automatic adjustment of the cutting angle of the corrugated paper, thereby helping to ensure the cutting effect of corrugated paper of different specifications.

[0055] After the corrugated paper is cut, the plurality of conveying rollers 31 drive the cut corrugated paper to move toward the storage box 30 , so that the cut corrugated paper moves and falls into the storage box 30 , and then the cut corrugated paper is collected and stored.
