[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] As attached Figure 1 With appendix Figure 2 As shown: An automatic telescopic conversion device for a belt conveyor includes a base plate 1. A conveyor belt assembly is provided on the upper surface of the base plate 1. The conveyor belt assembly includes a conveyor belt body 4 disposed above the base plate 1. The conveyor belt assembly also includes a set of L-shaped support frames 2 fixedly connected to the upper surface of the base plate 1. A sliding plate 3 is slidably connected to the inner wall of each L-shaped support frame 2. A transmission roller is installed between the set of L-shaped support frames 2 and between the set of sliding plates 3. The conveyor belt body 4 is disposed outside the set of transmission rollers. A motor is installed on the front of one of the L-shaped support frames 2. The motor is connected to the transmission roller. When the motor works, the transmission roller will drive the conveyor belt body 4 to rotate and convey materials.

[0026] As attached Figure 1 Appendix Figure 2 With appendix Figure 3 As shown: Top plates 6 are fixedly connected to the two sliding plates 3 on their opposite sides. Positioning frames 7 are slidably connected to the bottom of each top plate 6. The two positioning frames 7 are connected to the left and right sides of the bottom plate 1 on their opposite sides. By using the cooperation of the top plates 6 and the positioning frames 7, the sliding plates 3 can be supported, further improving the support effect of the sliding plates 3 on the conveyor belt body 4.

[0027] As attached Figure 4As shown: An adjustment component 5 is provided above the base plate 1. The adjustment component 5 includes an adjustment roller 501 located above the bottom end of the conveyor belt body 4. The adjustment roller 501 is located above the bottom end of the conveyor belt body 4, and the outer surface of the adjustment roller 501 is in contact with the conveyor belt body 4, which can press the conveyor belt body 4 to keep it taut. The left and right ends of the adjustment roller 501 are rotatably connected to a movable frame 502.

[0028] As attached Figure 3 Appendix Figure 4 With appendix Figure 5 As shown: The adjustment assembly 5 also includes an adjustment structure disposed above the base plate 1 for adjusting the conveying distance of the conveyor belt body 4. The adjustment structure of the adjustment assembly 5 includes a motor 503 mounted on the upper surface of the base plate 1. A first threaded rod 504 is mounted on the output end of the motor 503. A moving block 505 is threadedly connected to the outer surface of the first threaded rod 504. The left side of the moving block 505 is connected to the right side of the moving frame 502. The first threaded rod 504 connected to the motor 503 will continuously rotate on the moving block 505. Driven by the first threaded rod 504, the moving block 505 drives the moving frame 502 and the adjustment roller 501 to descend synchronously. The adjustment roller 501 will press the conveyor belt body 4 downward. A first bevel gear 506 is fixedly connected to the outer surface of the first threaded rod 504. A second bevel gear 507 is meshed with the outside of the first bevel gear 506. A second threaded rod 508 is fixedly connected to one side of the second bevel gear 507. A connecting rod 508 is threadedly connected to the outer surface of the second threaded rod 508. The connecting frame 509 has two top ends connected to the bottom surface of the slide plate 3. The first bevel gear 506 and the second bevel gear 507 are of the same size, and the first threaded rod 504 and the second threaded rod 508 are of the same diameter, ensuring that the first threaded rod 504 and the second threaded rod 508 maintain the same rotation speed. When the first threaded rod 504 rotates, the first bevel gear 506 meshing with it rotates accordingly, thereby driving the second bevel gear 507 to rotate synchronously. The rotation of the second bevel gear 507 drives the second threaded rod 508 to rotate stably on the connecting frame 509. As the second threaded rod 508 continues to rotate, the connecting frame 509 begins to move smoothly along the axial direction of the second threaded rod 508. During the movement, it will drive the slide plate 3 connected to it to move together. As the slide plate 3 moves away from one end of the conveyor belt body 4 and the downward-moving adjusting roller 501 pressing on the conveyor belt body 4, the conveyor belt body 4 will remain taut, thereby quickly completing the adjustment of the conveying distance of the conveyor belt body 4.

[0029] As attached Figure 4 As shown: A limiting ring 513 is fixedly connected to the outer surface of the first threaded rod 504. The limiting ring 513 is located above the first bevel gear 506. The limiting ring 513 can limit the descent distance of the moving block 505 to prevent the moving frame 502 from falling too far and causing collision damage.

[0030] As attached Figure 3 Appendix Figure 4 With appendix Figure 5 As shown: The other end of the second threaded rod 508 is rotatably connected to a reinforcing plate 510 on the outer surface of the second threaded rod 508. The bottom surface of each reinforcing plate 510 is connected to the upper surface of the base plate 1. The reinforcing plate 510 can be used to fix the second threaded rod 508, thereby ensuring the stability of the connecting frame 509 when it moves. A guide frame 511 is fixedly connected to the left side of the moving frame 502. The guide frame 511 and the connecting frame 509 are slidably connected to a support frame 512. The bottom end of the support frame 512 is connected to the upper surface of the base plate 1. By using the cooperation of the support frame 512 and the guide frame 511, the moving frame 502 and the connecting frame 509 can be guided, thereby ensuring their smooth movement.

[0031] Working principle: When the conveying distance of the conveyor belt body 4 needs to be adjusted, the control motor 503 starts working, and the first threaded rod 504 connected to it rotates at high speed. Simultaneously, the first bevel gear 506 meshing with the first threaded rod 504 rotates, which in turn drives the second bevel gear 507 to rotate synchronously. The rotation of the second bevel gear 507 drives the second threaded rod 508 to rotate stably on the connecting frame 509. As the second threaded rod 508 continues to rotate, the connecting frame 509 begins to move smoothly along the axial direction of the second threaded rod 508. During the process, the connected slide plate 3 will move together. The slide plate 3 will gradually move to the inside of the conveyor belt body 4. At the same time, the first threaded rod 504 will continue to rotate on the moving block 505. Driven by the first threaded rod 504, the moving block 505 will drive the moving frame 502 and the adjusting roller 501 to descend synchronously. The downward displacement of the adjusting roller 501 will press the conveyor belt body 4 downward, keeping the conveyor belt body 4 in a taut state. This will quickly and accurately complete the adjustment of the conveying distance of the conveyor belt body 4 without stopping the machine, further ensuring the conveying efficiency.
