At this time, the motor 17 is started to drive the threaded shaft 18 to rotate so that the slider on the threaded shaft 18 moves downward until the sliding measuring structure 7 is close to the belt. Then, the bearing member 701 is manually rotated to release the clamping state of the clamping plate 712 and the push rod 706, so that the push rod 706 pushes the sliding member 702 to move forward. When the fixed measuring rod 703 is close to the area where the belt 11 needs to be repaired, the edge of the area where the belt 11 needs to be repaired is adjusted first. The points where the two fixed measuring rods 703 are connected to each other are on the same straight line. Then, the two sliding measuring rods 704 are dragged to slide on the fixed measuring rods 703 until the area formed by the two pairs of fixed measuring rods 703 and the sliding measuring rods 704 completely covers the area of ​​the belt 11 that needs to be repaired. The scale bar 705 on the fixed measuring rod 703 is read to obtain the size of the required repair rubber block. While measuring the size of the area of ​​the belt 11 that needs to be repaired, the debris on the belt 11 is cleaned through the nozzle 13 installed on the side of the carrier 701 to avoid affecting the repair quality. When adjusting the edge of the area of ​​the belt 11 that needs to be repaired and the point where the two fixed measuring rods 703 are connected to each other, the same straight line is formed. When the rubber patch is on a straight line, the sliding member 16 can also be pushed to slide on the thin rod 15 between the fixed cross frame 14 to adjust the position of the sliding measuring rod 704 and the fixed measuring rod 703; after the repair rubber block is selected and placed on the belt 11, the sliding measuring structure 7 is folded up, and the repair rubber block is pressed on the belt 11 by the pressure plate 2 10, and the heating plate 6 is heated by the heating rod 9. While heating, the threaded rod 4 is manually rotated so that the pressure plate 1 5 is tightly pressed on the pressure plate 2 10 to apply pressure. During this process, the temperature controller monitors and controls the temperature of the heating plate 6 in real time; after the hot vulcanization repair is completed, the pressure plate 2 10 and the pressure plate 1 5 are removed, and the rotation Positioning box 804, move the adjustment slider 802 so that the positioning box 804 tightly presses one side of the belt 11 against the positioning spoke 809 to fix the adjustment slider 802. In this process, the inclined surface 805 on the positioning box 804 is used to allow the belt 11 to enter the positioning box 804 along the inclined surface 805 and the belt groove 806, and then start the linear motor 807. The linear motor 807 drives the cutting knife 808 to move along the edge of the belt 11, thereby achieving the removal of the belt 11 during the pressure application process. The displacement and position deviation of the belt 11 will cause the repair belt to partially exceed the originally planned repair area, thereby ensuring that the edge of the belt 11 is smooth and avoiding affecting the use of the belt 11.
