[0003] However, during the long-term use of the belt, there is friction between the belt surface and the material, and between the belt and the roller, which causes scratches on the belt surface and even rust and breakage of the wire rope, which poses a safety hazard to the operation of the belt and must be replaced regularly. The existing belt conveyor generally uses two new and old belt reels to connect the new and old belts respectively, and uses a driving reel to drive the belt to move to complete the belt replacement. During the belt replacement process, the radius changes and the linear speed cannot be kept consistent, so the belt drive cannot play a synchronous role and it is difficult to put the belt on the driving reel. Therefore, the utility model proposes a belt conveyor belt retracting device to solve the above problems. Utility Model Content

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a belt conveyor belt retracting device, including a body 1, a rotating drum 2 and a rotating arm 3. The right side of the body 1 is provided with a rotating drum 2, and the left side of the body 1 is provided with a rotating arm 3. One end of the rotating arm 3 is provided with a retracting mechanism, and a belt 4 is sleeved between the retracting mechanism and the rotating drum 2. A group of feet 6 are symmetrically provided at the bottom of the body 1, and one of the feet 6 is provided with a rotating mechanism, which drives the rotating drum 2 to rotate, and the rotating drum 2 drives the belt 4 to rotate between it and the retracting mechanism. When the material is placed on one end of the belt 4, the material is driven to move to the other end of the belt 4 to automatically transport the material. The retracting mechanism is retractable and is used to adjust the distance between it and the rotating drum 2. When the distance is reduced, it is convenient for people to sleeve the belt 4 between the rotating drum 2 and the retracting mechanism, and then extend and reset to re-tighten the belt 4 to complete the replacement of the belt 4.

[0020] The retracting and releasing mechanism comprises a No. 1 guide roller 7, a slider 9, a slide groove 10 and a threaded rod 11. A slide groove 10 is provided at one end of the rotating arm 3. The interior of the slide groove 10 is slidably connected to the No. 1 guide roller 7. The outer wall of the left end of the rotating arm 3 is threadedly connected to the threaded rod 11. The left end of the threaded rod 11 is rotatably connected to the slider 9. The interior of the slider 9 is rotatably connected to the No. 1 guide roller 7 through a bearing. The threaded rod 11 is screwed in the positive direction to drive the slider 9 to slide back and forth in a straight line inside the slide groove 10. The slider 9 can drive the No. 1 guide roller 7 to move toward the inside of the body 1, so that the slider 9 no longer tightens the belt 4. At this time, the belt 4 is in a relaxed state. Then the entire belt conveyor is lifted and moved upward. People remove it from between the rotating drum 2 and the No. 1 guide roller 7, replace it with a new belt 4, and then put down the belt conveyor. The threaded rod 11 is screwed in the reverse direction to drive the slider 9 to move to the outside of the slide groove 10, and the slider 9 tightens the belt 4 again to complete the replacement of the belt 4.

[0021] Pins 13 are symmetrically provided on both sides of the body 1, and a groove 12 is provided on the right end of the rotating arm 3. The shape of the groove 12 is set to an L-shaped structure. The outer side of the pin 13 is threadedly connected with a threaded sleeve. When the slider 9 no longer tensions the belt 4, the threaded sleeve on the outer side of the pin 13 is turned forward to no longer clamp the rotating arm 3, and the rotating arm 3 can rotate around the pin 13. The rotating arm 3 rotates upward, and the distance between the slider 9 and the rotating drum 2 is further reduced, which makes it convenient for people to remove the belt 4. After replacing the new belt 4, the rotating arm 3 is turned downward to reset it, and the threaded sleeve on the outer side is turned reversely to clamp the rotating arm 3 in a locked position. Then, the threaded rod 11 is turned reversely to drive the slider 9 to move to the outside of the slide groove 10, and the slider 9 tensions the belt 4 again.

[0022] A support plate 5 is fixedly connected to the top of the body 1. The material of the support plate 5 is set to be a wire mesh plate. The top of the support plate 5 is connected to the top of the belt 4. The top of the support plate 5 is in contact with the top of the belt 4. The support plate 5 supports the belt 4. When the material falls on the top of the belt 4, the support plate 5 provides support force for the material.

[0023] The bottom of the rotating arm 3 is rotatably connected to a second guide roller 8 , the bottom of the second guide roller 8 is closely connected to the bottom of the belt 4 , and the top of the first guide roller 7 is closely connected to the top of the belt 4 .

[0024] The rotating mechanism includes a rotating shaft 14 and a motor 15. The motor 15 is installed on the top of the foot 6. The output end of the motor 15 is fixedly connected to the rotating shaft 14. A connecting key is provided on the outer side of the rotating shaft 14. A key slot is provided on the inner side of the rotating drum 2. The rotating shaft 14 is engaged with the key slot through the connecting slot. The rotating shaft 14 is engaged with the rotating drum 2 through the connecting key. The output end of the motor 15 can drive the rotating shaft 14 to rotate. The rotating shaft 14 drives the rotating drum 2 to rotate. The rotating drum 2 cooperates with the No. 1 guide roller 7 and the No. 2 guide roller 8 to drive the belt 4 to rotate, thereby driving the material at one end to move to the other end, so as to automatically transport the material.

[0025] One end of the motor 15 is fixedly connected to a flange, and mounting holes are symmetrically provided on both sides of the flange and the top of the anchor 6. Bolts are provided inside the mounting holes, and the flange is fixedly connected to the anchor 6 through the bolts.

[0026] For this belt conveyor, the threaded rod 11 is turned forward to rotate and drive the slider 9 to slide back and forth in a straight line inside the slide groove 10. The slider 9 can drive the No. 1 guide roller 7 to move toward the inside of the body 1, so that the slider 9 no longer tensions the belt 4. The threaded sleeve on the outside of the pin shaft 13 is turned forward to no longer clamp the rotating arm 3. The rotating arm 3 can rotate around the pin shaft 13. The rotating arm 3 rotates upward, and the distance between the slider 9 and the rotating drum 2 is further reduced, which is convenient for people to remove the belt 4. After replacing the new belt 4, the rotating arm 3 is turned downward to reset it, and the threaded sleeve on the outside is turned reversely to clamp the rotating arm 3 in the locked position. Then, the threaded rod 11 is turned reversely to drive the slider 9 to move to the outside of the slide groove 10, and the slider 9 tightens the belt 4 again, which is convenient for people to replace the belt 4.
