[0035] According to another aspect of the present invention, a method for storing a telescopic conveyor belt is provided, including the following steps:

[0036] S1. During the process of storing the belt, the rotating screw rod 305 can be driven by the second motor 304 to rotate, so that the positioning frame 307 moves downward, and the first rotating bar 401 and the second rotating bar 402 can be adjusted to contract horizontally around the fixed rod 406;

[0037] S2. After confirming that the adjustment is completed, drive the carriage assembly 5 and the telescopic assembly 4 to move through the second universal wheel 502 and the third universal wheel 806 respectively, so that the distance between the carriage assembly 5 and the fixed frame assembly 1 can be reduced to the minimum;

[0038] S3. At the same time, make the telescopic pallet 802 move inside the load-bearing pallet 801 through the slidably connected load-bearing pallet 801 and telescopic pallet 802, and realize the belt storage operation of the entire conveyor belt through the moving carriage assembly 5 and telescopic assembly 4.

[0039] During the elongation process, with the movement of the positioning frame 307 and the rotation of the first rotating bar 401 and the second rotating bar 402, the parallelogram mechanism formed by the multiple first rotating bars 401 and the second rotating bars 402 deforms. The horizontal section is converted from the vertical direction to the horizontal direction, the entire device is elongated, and at the same time the vertical section becomes shorter, compensating for the upper part of the belt. And through the simulation analysis of the model, the following curve is obtained. Figure 8 It can be seen that the total length of the belt changes little and is approximately in a quadratic function relationship.

[0040] During the elongation process, the pre-tightening assembly 7 adjusts the sliding frame 501 up and down to keep a certain tension. And for the sliding assembly 8 part, due to the horizontal movement of the parallelogram link structure, the positions of the load-bearing pallet 801 and the telescopic pallet 802 change evenly, and the distance between the load-bearing pallet 801 and the telescopic pallet 802 also elongates. After reaching the predetermined position, the first motor 204 is turned on to drive the driving roller 105 to rotate to realize the rotation processing of the conveyor belt.

[0041] Through the above steps, by setting an adjustable telescopic structure and a pre-tightening compensation structure to replace the original spliced conveyor belt, the adjustment of the conveying distance can be realized, so as to solve to a certain extent the problem that in the process of using the existing conveyor belt, the conveying distance often needs to be adjusted, but the existing spliced structure often causes that when multiple conveyor belts are not in use, the multiple unfolded conveyor belts often increase the floor area of the entire conveying structure. At the same time, through the setting of the driving component, the rotation adjustment of the conveyor belt can be realized, and at the same time, through the adjustment component 3, the length adjustment of the conveyor belt can be realized. Through the setting of the telescopic component 4, the elongation and contraction of the conveyor belt can be realized. Through the setting of the carriage component 5, the movement adjustment of the conveyor belt can be realized. Through the setting of the compensation component 6, the compensation for the extended length of the conveyor belt can be realized. Finally, through the setting of the pre-tightening component 7, the pre-tightening adjustment of the conveyor belt after the adjustment is completed can be realized. Through the setting of the sliding component 8, the bottom support of the top position of the conveyor belt can be realized.
