A second guide roller 5 is arranged on the inner side of the outer box body 1 at the side of the first guide roller 4. Two first guide rollers 4 and second guide rollers 5 are symmetrically arranged. The two first guide rollers 4 and second guide rollers 5 are respectively distributed in a staggered manner. The tube sandpaper is fed into the outer box body 1 through the conveying roller 2, and is guided by the first guide roller 4 and the second guide roller 5, and is output from the right side of the outer box body 1. The two groups of first guide rollers 4 and second guide rollers 5 form a Z-shaped conveying path for the tube sandpaper inside the outer box body 1, thereby increasing the tension of the tube sandpaper.

[0023] A connecting component 6 is provided between the front end of the first guide roller 4 and the outer box body 1, and the connecting component 6 includes a connecting block 61. Connecting grooves 62 are provided on the front and rear sides of the surface of the outer box body 1. The connecting block 61 and the connecting groove 62 are slidably connected. The connecting block 61 and the first guide roller 4 are rotatably connected through a connecting shaft. The inner side of the connecting groove 62 is located on the side of the connecting block 61 and a resistance rod 63 is fixedly installed. A pressure sensor is provided on the resistance rod 63. A compression spring 64 is sleeved on the outer side of the resistance rod 63. One end of the compression spring 64 is fixedly connected to the outer box body 1, and the other end of the compression spring 64 is fixedly connected to the connecting block 61. The end of the resistance rod 63 away from the outer box body 1 is fit-connected to the connecting block 61. An adjusting component 7 is provided between the front and rear ends of the second guide roller 5 and the outer box body 1. The adjusting component 7 includes a movable block 71. Movable grooves 72 are provided on the front and rear sides of the surface of the outer box body 1. The movable groove 72 and the movable block 71 are slidably connected. Then, the movable block 71 and the second guide roller 5 are rotatably connected through the connecting shaft, and an electric push rod 73 is fixedly installed on the surface of the outer box body 1 at the side of the movable groove 72. The output end of the electric push rod 73 is fixedly connected through the fixed block and the movable block 71. The two ends of the first guide roller 4 are provided with a connecting component 6, so that the tension applied by the tube sandpaper to the first guide roller 4 is sensed by the pressure sensor, and the pressure applied to the first guide roller 4 in normal transportation is set to a certain range. When the pressure applied exceeds the range, it means that the tension is too large. When the tension is too large, the adjustment component 7 can adjust the position of the second guide roller 5, and the electric push rod 73 is used to drive the movable block 71 to move up and down, shorten the distance between the first guide roller 4 and the second guide roller 5, reduce the conveying tension of the tube sandpaper, avoid breakage, and when the tension is too small, increase the distance between the first guide roller 4 and the second guide roller 5, maintain a certain tension, and ensure the conveying effect;

[0024] A monitoring component 8 is provided at the left end of the inner side of the outer box body 1, and an alarm 9 is fixedly installed on the side of the upper end of the outer box body 1. The monitoring component 8 includes an infrared generating module 81 and an infrared receiving module 82. The infrared generating module 81 is a rectangular structure. The infrared generating module 81 and the infrared receiving module 82 are symmetrically distributed up and down. The infrared generating module 81 and the infrared receiving module 82 are both fixedly connected to the outer box body 1. A control box 83 is provided at the upper end of the surface of the outer box body 1. The control box 83 is electrically connected to the infrared generating module 81, the infrared receiving module 82, the electric push rod 73, the pressure sensor, and the alarm 9. An information processing module is provided in the control box 83. After the tube sandpaper enters the outer box body 1, it is located between the infrared generating module 81 and the infrared receiving module 82, thereby blocking the light of the infrared generating module 81. The infrared receiving module 82 does not receive the light. At this time, it is normal transportation and no break occurs. Then, when it breaks, the infrared receiving module 82 can sense it in time and sound an alarm through the alarm 9, which is convenient for personnel to shut down the equipment in time and handle it, thereby improving practicality.

[0025] During operation, the control box 83 is connected to an external power supply to supply power to the equipment. The tube sandpaper is fed into the outer box body 1 through the conveying roller 2, and is guided by the first guide roller 4 and the second guide roller 5, and is output from the right side of the outer box body 1. The two groups of first guide rollers 4 and second guide rollers 5 form a Z-shaped conveying path for the tube sandpaper inside the outer box body 1, increasing the tension of the tube sandpaper, so that the first guide roller 4 is subjected to a certain pressure. In normal conveying, the pressure on the first guide roller 4 is set within a certain range. When the pressure exceeds the range, the tension is too large. Therefore, when the pressure sensor senses that the pressure is large, the electric push rod 73 is used to drive the movable block 71 to move up and down, shortening the first guide roller 4. The distance between the guide roller 4 and the second guide roller 5 is increased to reduce the conveying tension of the tube sandpaper and avoid breakage. When the pressure is small, the distance between the first guide roller 4 and the second guide roller 5 is increased to maintain a certain tension to ensure the conveying effect. At the same time, after the tube sandpaper enters the outer box 1, it is located between the infrared generating module 81 and the infrared receiving module 82, thereby blocking the light of the infrared generating module 81. The infrared receiving module 82 does not receive the light. At this time, it is normal transportation and no breakage occurs. When it breaks, the infrared receiving module 82 can sense it in time and sound an alarm through the alarm 9, which is convenient for personnel to shut down the equipment and handle it in time, thereby improving practicality.
