[0036] When the belt 213 is in the deviation correction process, one side of the belt 213 will inevitably be subjected to tension, at this time, in order to avoid the belt 213 being pulled and broken, the part of the belt 213 pulled by the tensioning roller 232 will be compensated, when the belt 213 is subjected to tension, the tensioning roller 232 will move upward, thereby effectively avoiding the belt 213 being pulled and broken.

[0037] Meanwhile, the contents not described in detail in the specification all belong to the existing technology known to those skilled in the art.

[0038] When working, the driving motor 214 is started to drive the transmission roller 212 to rotate, so that the belt 213 conveys the material. In the process, the infrared sensor 3 irradiates light to the side of the belt 213, and receives the reflected infrared light, and feeds back the signal to the controller 4. The distance between the belt 213 and the infrared sensor 3 is calculated by calculating the time difference from emission to reception. When the distance is too far or too close, the belt 213 deviates. At this time, the first piston rod 242 is separated from the first limiting hole 12 to release the limiting of the fixed frame 211, and the second piston rod 245 is separated from the second limiting hole 236 to release the limiting of the roller seat 231. Then, the double-shaft motor 221 is started to drive the rotating shaft 222 to rotate, drive the two rotating shafts 222 to rotate, cooperate with the first bevel gears 224 at both ends to make the two second bevel gears 225 rotate in opposite directions, and make the two fixed frames 211 rotate synchronously through the corresponding connecting shafts 226, so that the angle of the two transmission rollers 212 in the horizontal direction changes. By controlling the inclination angle of the two transmission rollers 212, the belt 213 is forced to move in the opposite direction of deviation. When the infrared sensor 3 senses that the belt 213 returns to the set value, the belt 213 has been corrected, and the two transmission rollers 212 return to the parallel state, effectively avoiding the deformation or folding of the belt 213 caused by the extrusion force on the side of the belt 213 in the correction process, improving the correction effect. After the correction is completed, the first piston rod 242 is inserted into the first limiting hole 12 to fix the fixed frame 211, and the second piston rod 245 is inserted into the second limiting hole 236 to fix the roller seat 231, thereby improving the stability of the device. During the correction of the belt 213, one side of the belt 213 will inevitably be subjected to tension. At this time, in order to avoid the belt 213 being pulled and broken, the part of the belt 213 restrained by the tensioning roller 232 will compensate. When the belt 213 is subjected to tension, the tensioning roller 232 moves upward, thereby effectively avoiding the belt 213 being pulled and broken. After the belt 213 is corrected, the roller seat 231 is fixed by the cooperation of the second piston rod 245 and the fixed block 235, so that the position of the tensioning roller 232 is fixed and cannot move up and down, avoiding the collapse of the roller seat 231 caused by the upward movement of the tensioning roller 232 due to the excessive weight of the material when conveying the material.
