The two groups of motors 6 have the same speed and opposite directions. The output end of the motor 6 is connected to the active roller 7. The front and rear groups of active rollers 7 are connected by a shaft rod. Adjusting rollers 9 are installed on the edges of both sides of the frame 1. The adjusting rollers 9 are provided with two front and rear groups, each group is provided with two left and right ones. An upper tensioning wheel 8 is installed below the inner side of the adjusting roller 9. Lower tensioning wheels 10 are respectively installed on both sides of the front and back of the conveying platform 4. There are four active rollers 7, upper tensioning wheels 8, adjusting rollers 9 and lower tensioning wheels 10 respectively, which form four groups on the frame 1 to drive the shielding door 5 together. Each group of lower tensioning wheels 10 is on the same vertical line as the lower tensioning wheel 10;
