A baffle 32 is fixedly arranged on the sandpaper storage rack 3 and on the side of the guide plate 31 away from the unwinding rack 2.

[0025] Reference Figure 2 , 3The drive assembly is provided with two groups and is respectively arranged on both sides of the guide plate 31. The drive assembly includes a servo cylinder 33 and a connecting rod 34. The servo cylinder 33 is fixedly arranged on the sandpaper storage rack 3, one end of the connecting rod 34 is hinged to the guide plate 31, and the other end of the connecting rod 34 is hinged to the piston rod of the servo cylinder 33, and the connecting rod 34 is hinged to the guide plate 31. The hinge axis; by driving the guide plate 31 to rotate, the angle formed between the upper surface of the guide plate 31 and the baffle plate 32 is an acute angle, and the sandpaper roll to be replaced can be placed on the guide plate 31, and the sandpaper roll will not slide off the guide plate 31. When the sandpaper roll needs to be transported to the unwinding rack 2, the guide plate 31 is driven to rotate, so that the angle formed between the upper surface of the guide plate 31 and the baffle plate 32 is an obtuse angle, and the sandpaper roll will roll along the surface of the guide plate 31 under the action of gravity and enter the unwinding rack 2.

[0026] Reference Figure 4 The unwinding frame 2 is provided with an unwinding mechanism for driving the sandpaper roll to rotate, and the unwinding mechanism includes a first turntable 21 rotatably arranged on the unwinding frame 2, a sliding frame 22 slidably arranged on the unwinding frame 2 along the axial direction of the first turntable 21, and a second turntable 23 rotatably arranged on the sliding frame 22. The rotation axes of the first turntable 21 and the second turntable 23 are both horizontally arranged, and the central axes of the first turntable 21 and the second turntable 23 coincide with each other, and guide pillars 24 are coaxially fixedly arranged at one end of the first turntable 21 and the second turntable 23 close to each other.

[0027] Reference Figure 4 The unwinding frame 2 is provided with a second driving source 25 for driving the first turntable 21 to rotate. The second driving source 25 includes a second motor. The second motor is fixedly arranged on the unwinding frame 2. The output shaft of the second motor is coaxially fixedly connected to the first turntable 21.

[0028] Reference Figure 4 The unwinding frame 2 is also provided with a first driving member 26 for driving the sliding frame 22 to slide. The first driving member 26 includes a pushing cylinder, which is fixedly arranged on the unwinding frame 2. The piston rod of the pushing cylinder is fixedly connected to the sliding frame 22. After the sandpaper roll is transported to the unwinding frame 2, the position of the sandpaper roll is adjusted so that the two sides of the ring shaft in the middle of the sandpaper roll are accurately aligned with the first turntable 21 and the second turntable 23 respectively, and the sliding frame 22 is driven to slide in the direction close to the first turntable 21, and the sandpaper roll is pushed to move in the direction close to the first turntable 21, so that the first turntable 21 and the second turntable 23 are respectively pressed against the two sides of the ring shaft of the sandpaper roll, and the guide posts 24 on the first turntable 21 and the second turntable 23 are both inserted into the ring shaft of the sandpaper roll. Then, the first turntable 21 is driven to rotate by the second motor, which can drive the sandpaper roll to rotate.

When the sandpaper roll needs to be replaced, the used sandpaper roll on the unwinding rack 2 is first taken down, and the sandpaper storage rack 3 is driven to move up to make the sandpaper roll rise to the side position of the lifting platform 27, and then the guide plate 31 is driven to rotate, so that the angle formed between the upper surface of the guide plate 31 and the baffle plate 32 is an obtuse angle. Under the action of gravity, the sandpaper roll will roll along the surface of the guide plate 31, so that the sandpaper roll enters the placement groove 271 of the lifting platform 27.

[0032] Afterwards, the position of the sandpaper roll on the unwinding frame 2 is adjusted by driving the lifting platform 27 to rise and fall, so that the two sides of the ring shaft in the middle of the sandpaper roll are accurately aligned with the first turntable 21 and the second turntable 23 respectively, and the sliding frame 22 is driven to slide in the direction close to the first turntable 21, and the sandpaper roll is pushed to move in the direction close to the first turntable 21, so that the first turntable 21 and the second turntable 23 are respectively pressed against the two sides of the ring shaft of the sandpaper roll, and the guide pillars 24 on the first turntable 21 and the second turntable 23 are both inserted into the ring shaft of the sandpaper roll, and then the first turntable 21 is driven to rotate by the second motor, which can drive the sandpaper roll to rotate, and the automatic feeding of the sandpaper roll can be realized, thereby improving the production efficiency and reducing the labor intensity of the staff.
