DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.

[0014] like Figure 1 As shown, a device for removing defects from decorative paper comprises a tractor 1, a cutting machine 2 and a conveyor line 3 which are arranged in sequence. Two tractor rollers 4 and a guide roller 5 are installed inside the tractor 1. The two tractor rollers 4 are arranged up and down. The decorative paper is wound around the tractor rollers 4 and then passes through the guide rollers 5 to be conveyed backward in an "S" shape. An industrial camera 6 is arranged in front of the tractor 1. The industrial camera 6 is installed above the decorative paper through a gantry bracket. The industrial camera 6 takes a picture of the surface of the decorative paper passing by and sends it to the background for analyzing the surface defects. A cutting platform 7 is installed inside the tractor 1. A long strip-shaped cutting knife seat 8 is arranged above 7, and a cutting knife groove 9 is processed on the surface of the cutting platform 7. A cutting knife 10 is connected to the bottom of the cutting knife seat 8 corresponding to the cutting knife groove 9, wherein an "L"-shaped mounting groove is processed at the bottom of the cutting knife seat 8, and an "L"-shaped handle is processed at the end of the cutting knife 10 accordingly. The handle is inserted into the mounting groove and locked by a side bolt. A support plate is connected above the cutting machine 2, and an oil cylinder 11 is symmetrically installed on the support plate. The piston end of the oil cylinder 11 passes through the support plate and is connected to the cutting knife seat 8 through a joint, and the oil cylinder 11 controls the cutting knife 10 to cut the decorative paper.

[0015] A measuring roller 12 is provided at the front end of the cutting machine 2 , and the measuring roller 12 measures the length of the decorative paper passing through by the number of rotations. A pressing roller 13 is provided above the measuring roller 12 , and the pressing roller 13 cooperates with the measuring roller 12 to convey the decorative paper to the cutting platform 7 .

[0016] The conveyor line 3 adopts a belt conveyor line. The conveyor line 3 is located behind the cutting platform 7. The surface of the conveyor line 3 is located below the cutting platform 7. The decorative paper output by the cutting platform 7 can just fall on the conveyor line 3. A notch is provided on the conveyor line 3. Connecting rods are installed on both sides of the notch. A transmission shaft 14 is provided between the connecting rods. A flip plate 15 is installed on the transmission shaft 14. A cylinder 16 is symmetrically installed on the side of the conveyor line 3 in the notch. The piston end of the cylinder 16 is connected to the flip plate 15 through a cross universal joint connecting rod 17. A connecting seat is provided at the bottom of the flip plate 15, and a short shaft is installed in the connecting seat. The two ends of the cross universal joint connecting rod 17 are respectively connected to the short shaft and the piston end of the cylinder 16 through fisheye joints.

[0017] A waste box 18 is provided at the bottom of the notch of the conveyor line 3. After the industrial camera 6 detects a defect, an instruction is issued, the measuring roller 12 calculates the length, and the piston end of the cylinder 16 retracts to flip the flip plate 15 to cut off the conveyor line 3. After the defective decorative paper passes through the cutting machine 2, the cutting knife 10 cuts it, and then the defective decorative paper falls into the waste box 18. At this time, the flip plate 15 flips over again and lies flat, and the remaining decorative paper continues to be conveyed backward.

[0018] The present invention is not limited to the described embodiments. Those skilled in the art may make some modifications or changes without departing from the spirit and scope of the present invention, that is, the scope of disclosure. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
