[0064] When the first upper clamping block 33 extends upward, an opening is formed between the first upper clamping block 33 and the first lower clamping block 32, and the edge of the conveyor belt 5 extends into the opening. When the first upper clamping block 33 is controlled to retract downward, the first upper clamping block 33 and the first lower clamping block 32 clamp the conveyor belt 5.

[0071] In the embodiment of the present application, an engaging groove, a first limiting plate 311 and a second limiting plate 312 are provided to limit the guide slider 31 on the U-shaped guide rail 2, so that the guide slider 31 and the U-shaped guide rail 2 remain engaged and prevent the two from separating.

[0072] In one embodiment, the guide clamp assembly 3 further includes a first hydraulic rod 34 , and the first upper clamp block 33 is mounted on the guide slide block 31 via the first hydraulic rod 34 .

[0073] The first hydraulic rod 34 is hydraulically controlled to achieve upward and downward telescopic movement, thereby controlling the upward and downward telescopic movement of the first upper clamping block 33 .

[0074] In one embodiment, the guide fixture assembly 3 further includes a driving member 35 connected to the guide slider 31 for driving the guide slider 31 to slide along the U-shaped guide rail 2 .

[0075] The driving member 35 can be a rotating motor. As an example, at least one roller is installed on the output shaft of the rotating motor so that the outer peripheral surface of the roller contacts the U-shaped guide rail 2. When the rotating motor rotates, the roller drives the guide slider 31 to slide along the U-shaped guide rail 2. By controlling the forward and reverse rotation of the rotating motor, the guide slider 31 can be driven to slide forward and reverse along the U-shaped guide rail 2.

[0077] Specifically, along the length direction of the conveyor belt 5, the first support block is arranged in front of and / or behind the first lower clamping block 32, and the upper surface of the first support block is arranged as a smooth curved surface. The first support block is used to support the conveyor belt 5, and the first support block is arranged as a smooth curved surface to ensure the smooth passage of the conveyor belt 5.

[0078] Preferably, the first support block can be configured as a cylindrical roller axially along the width direction of the conveyor belt 5, which can reduce the friction between the conveyor belt 5 and the first support block.

[0079] In one embodiment, the support fixture assembly 4 includes a support slider 41, a second lower clamp block 42 and a second upper clamp block 43;

[0080] The support slider 41 is slidably supported on the U-shaped guide rail 2, and the upper end of the support slider 41 extends a second lower clamping block 42 inwardly, and the second upper clamping block 43 is telescopically installed on the support slider 41, and the second upper clamping block 43 is located above the second lower clamping block 42.

[0081] Specifically, the support slider 41 is used to connect with the U-shaped guide rail 2 , the second lower clamping block 42 is formed on the support slider 41 , and the second upper clamping block 43 is installed on the support slider 41 in a telescopic manner.

[0082] When the second upper clamping block 43 extends upward, an opening is formed between the second upper clamping block 43 and the second lower clamping block 42, and the edge of the conveyor belt 5 extends into the opening. The second upper clamping block 43 is controlled to retract downward, and the second upper clamping block 43 and the second lower clamping block 42 clamp the conveyor belt 5.

[0083] In one embodiment, a supporting groove is provided on the outer side of the supporting slide block 41, and the U-shaped guide rail 2 is detachably supported in the supporting groove.

[0084] Specifically, the opening width of the support groove is equal to or slightly larger than the thickness of the U-shaped guide rail 2, so that the support groove can just fit into the U-shaped guide rail 2. In the absence of external force, the support slider 41 can be stably stuck on the U-shaped guide rail 2. Under the influence of external force, the support slider 41 can be detached from the U-shaped guide rail 2.

[0085] In one embodiment, the supporting clamp assembly 4 further includes a second hydraulic rod 44 , and the second upper clamping block 43 is mounted on the supporting sliding block 41 via the second hydraulic rod 44 .

[0086] The second hydraulic rod 44 is hydraulically controlled to achieve upward and downward telescopic movement, thereby controlling the upward and downward telescopic movement of the second upper clamping block 43 .

[0087] Preferably, a control unit can be provided, and the hydraulic cylinder 12, the first hydraulic rod 34 and the second hydraulic rod 44 of the support seat 1 are all communicatively connected or linked to the control unit. The control unit can control the extension and retraction of the hydraulic cylinder 12, the first hydraulic rod 34 and the second hydraulic rod 44 according to preset action logic and action flow, thereby realizing the automation of the conveyor belt flipping operation.

[0088] The embodiment of the present application uses a second hydraulic rod 44 to control the opening and clamping of the support clamp assembly 4.

[0092] Preferably, the second support block 45 can be configured as a cylindrical roller axially along the width direction of the conveyor belt 5 , which can reduce the friction between the conveyor belt 5 and the second support block 45 .

[0093] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0094] Conveyor belt turning method:

[0095] The technical solution of the present application also provides a conveyor belt turning method based on the conveyor belt turning device as described above, such as Figure 8 As shown, the following steps are included:

[0096] Step S801: supporting the conveyor belt frame to a set height and adjusting the conveyor belt to a relaxed state;

[0097] Step S802: placing the conveyor belt turning device on the rear roller of the conveyor belt, controlling the lifting and lowering of the lifting support frame, and adjusting the height of the U-shaped guide rail to be flush with the conveyor belt;

[0098] Step S803: adjusting the guide clamp assembly and the support clamp assembly to slide to both sides of the opening of the U-shaped guide rail, and controlling the guide clamp assembly and the support clamp assembly to clamp both sides of the conveyor belt respectively;

[0099] Step S804: controlling the lifting support frame to rise so that the guide clamp assembly and the support clamp assembly are higher than the tail roller;

[0100] Step S805: driving the guide fixture assembly and the support fixture assembly to synchronously slide to the connection end of the U-shaped guide rail;

[0101] Step S806: driving the guide fixture assembly to slide along the U-shaped guide rail to the position of the support fixture assembly, and during the sliding process of the guide fixture assembly, the support fixture assembly is separated from the U-shaped guide rail;

[0102] Step S807: After the guide fixture assembly slides to the target position, the support fixture assembly is supported to a position on the U-shaped guide rail opposite to the guide fixture assembly;

[0103] Step S808: Control the guide clamp assembly and the support clamp assembly to release the conveyor belt, and control the conveyor belt to continue conveying until the conveyor belt is turned over as a whole.

[0104] like Figure 4 As shown, the conveyor belt transmission mechanism includes a conveyor belt 5, a driving roller 6, a tail roller 7 and a tensioning roller 8. The conveyor belt 5 is an annular conveyor belt connected end to end, and its inner surface contacts the driving roller 6, the tail roller 7 and the tensioning roller 8 in sequence. The driving roller 6, the tail roller 7 and the tensioning roller 8 roll together to drive the conveyor belt 5 to roll. The tensioning roller 8 can move up and down. Moving the tensioning roller 8 downward can adjust the tightening of the conveyor belt 5; moving the tensioning roller 8 upward can adjust the loosening of the conveyor belt 5.

[0105] In step S801, firstly, a support frame 9 (see Figure 1 ) Raise the conveyor belt transmission mechanism as a whole to the set height, and then adjust the tensioning roller 8 to move upward to make the conveyor belt 5 in a relaxed state.

[0106] Step S802 starts installing the conveyor belt turning device, such as Figure 1 , 5 As shown, the conveyor belt turning device is installed at one end of the tail roller 7 so that the tail roller 7 is located in the opening of the U-shaped guide rail 2. At the same time, the lifting support frame is controlled to be extended and retracted to adjust the height of the U-shaped guide rail 2 to keep it flush with the conveyor belt 5.

[0107] Step S803 controls the guide clamp assembly 3 and the support clamp assembly 4 to slide to both sides of the opening of the U-shaped guide rail 2, so that the guide clamp assembly 3 and the support clamp assembly 4 clamp both sides of the conveyor belt 5 in the width direction respectively.

[0108] Steps S804-S807 are used to realize the exchange of the positions of the guide clamp assembly 3 and the support clamp assembly 4, so as to partially turn over the conveyor belt 5. Specifically:

[0109] First execute step S804 to control the lifting support frame to extend upward, support the U-shaped guide rail 2 to be higher than the conveyor belt 5, and make the guide clamp assembly 3 and the support clamp assembly 4 higher than the tail roller 7 to prevent the guide clamp assembly 3 and the support clamp assembly 4 from interfering with the tail roller 7 during the subsequent flipping process.

[0110] Step S805 controls the guide clamp assembly 3 and the support clamp assembly 4 to slide synchronously to the connection end of the U-shaped guide rail 2, and pulls the conveyor belt 5 to the connection end of the U-shaped guide rail 2. Figure 6 As shown, the connection end of the U-shaped guide rail 2 is semicircular, and the guide clamp assembly 3 and the support clamp assembly 4 slide to a position tangent to the semicircle.

[0111] Step S806 drives the guide fixture assembly 3 along Figure 6 The direction of the arrow shown slides toward the position of the support clamp assembly 4. During the sliding process, the guide clamp assembly 3 drives one side of the conveyor belt 5 to slide. Under the pulling action of the conveyor belt 5, the support clamp assembly 4 disengages from the U-shaped guide rail 2, and the support clamp assembly 4 remains clamped on one side of the conveyor belt 5.

[0112] Step S807: The guide clamp assembly 3 slides to the original position of the support clamp assembly 4. At this time, the support clamp assembly 4 is supported to a position opposite to the guide clamp assembly 3, that is, the original position of the guide clamp assembly 3. At this point, the conveyor belt 5 is partially turned over. The state of the conveyor belt 5 is as follows: Figure 7 shown.

[0113] Step S808 first controls the guide clamp assembly 3 and the support clamp assembly 4 to loosen the conveyor belt, and the guide clamp assembly 3 and the support clamp assembly 4 replace the tail roller 7 to support the conveyor belt; then the conveyor is started, and the drive roller 6 is controlled to roll so that the conveyor belt 5 continues to convey. As the conveyor belt 5 is conveyed, the flipping area of ​​the conveyor belt 5 gradually increases until the conveyor belt 5 rolls one circle and the conveyor belt 5 completes the overall flipping.

[0114] In the embodiment of the present application, the conveyor belt is partially flipped over by controlling the conveyor belt flipping device, and then the entire conveyor belt is flipped over as the conveyor belt is transported. The flipping process is simple and easy to operate, the flipping efficiency is high, and a large number of manpower is not required.

[0115] The above description is only the principle and preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this field, the implementation methods obtained by appropriately combining the technical solutions disclosed in different embodiments are also included in the technical scope of the present invention. On the basis of the principle of the present application, several other variations can be made, which should also be regarded as the protection scope of the present application.
