Figures 1 to 3As shown, it includes: a body 1, a transmission unit 2, a correction unit 3, an adjustment unit 4 and a light curtain 5; the transmission unit 2 is arranged on the body 1, and is used for transmitting corrugated paper on the body 1; the correction unit 3 is arranged on the transmission unit 2, and is used to keep the two ends of the transmission automatically aligned; the light curtain 5 is installed on the body 1, and is used to sense and detect the alignment of the two ends of the corrugated paper; the adjustment unit 4 is symmetrically arranged on the body 1, and is used to adjust the offset corrugated paper; wherein the adjustment unit 4 includes a cam 6, a connecting seat 7, a control motor 8 and a fixing rod 9, the control motor 8 is respectively installed on both sides of the body 1, the fixing rod 9 is respectively connected to the two control motors 8, the connecting seat 7 is installed between the two fixing rods 9, the fixing rod 9 and the connecting seat 7 are rotated together, and the two fixing rods 9 do not contact each other, so that each end is independently transmitted, and the cam 6 is arranged on the fixing rod 9.

[0024] When adjusting the alignment of both sides of the corrugated paper, the light curtain 5 monitors the transmitted corrugated paper. The end of the corrugated paper tilts backward and drives the control motor 8. The output end of the control motor 8 drives the fixed rod 9 and the cam 6 at the connecting end. The cam 6 drives the corrugated paper forward until the transmission at both ends of the corrugated paper can ensure the same flush transmission.

[0025] With the above basic structure, the transmission unit 2 includes a transmission roller 10, a guide roller 11 and a servo motor 12. The servo motor 12 is installed on the side of the machine body 1, the transmission roller 10 is installed on the output end of the servo motor 12, and the guide roller 11 is rotatably arranged on the machine body 1. Under normal working conditions, the servo motor 12 is in an on state, the driving shaft of the servo motor 12 drives the transmission roller 10 to transmit, and the guide roller 11 assists the transmission of the corrugated paper, and the two together play a conductive role in the transmission of the corrugated paper.

[0026] Using the above basic structure, the correction unit 3 includes a first transmission part 13, a second transmission part 14 and a connecting frame 15; the first transmission part 13 is used to drive the guide roller 11 on one side to transmit, the second transmission part 14 is used to drive the guide roller 11 on the other side to transmit, and the connecting frame 15 is used to connect the first transmission part 13 and the second transmission part 14.

[0027] With the above basic structure, the first transmission part 13 includes a first bevel gear 16 , a second bevel gear 17 and a connecting rod 18 . The first bevel gear 16 is mounted on the guide roller 11 . The second bevel gear 17 and the first bevel gear 16 are meshed with each other. The connecting rod 18 is connected to the second bevel gear 17 .

The width of the transmitted corrugated paper is smaller than the spacing between the first transmission part 13 and the second transmission part 14 arranged on both sides. The deviation correction unit 3 enables the guide roller 11 to maintain a certain spacing and stable transmission in the vertical direction, thereby reducing the deviation error caused by the mechanical transmission of the corrugated paper.

[0030] With the above basic structure, the cams 6 are arranged equidistantly from small to large. The volume of the cams 6 decreases from the two ends to the middle, so that the offset corrugated paper on both sides is driven by the larger cam 6 to drive the displacement of the transmission, thereby adjusting the misaligned corrugated paper.

[0031] Correction units 3 are provided on both sides of the machine body 1. Under normal operation, the corrugated paper can be transmitted smoothly on both sides with the correction unit 3; when there is a problem with the automatic edge monitoring of the light curtain 5, the adjustment unit 4 pushes the corrugated paper on one side and adjusts the corrugated paper moving forward to one side. After adjustment, the two sides can be kept flat and aligned during transmission; the automated edge alignment operation realizes the relief of manual correction, edge alignment, and pull-down operations, thereby improving the efficiency of the transmission and edge alignment of the corrugated paper.
