[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0021] Example 1: Please refer to Figure 1 - Figure 3 A conveyor belt limiting device according to this embodiment includes a fixed frame 1 and a connecting block 2. A conveyor belt 4 is arranged inside the fixed frame 1. The connecting block 2 is located on the top of the conveyor belt 4. A base 5 is arranged at the bottom of the fixed frame 1. A rotating rod 3 is rotatably connected to one end of the connecting block 2. A turntable 7 is arranged on the top of the connecting block 2. A threaded rod 8 is fixedly connected to the bottom of the turntable 7. One end of the threaded rod 8 is threadedly connected to the inside of one end of the connecting block 2. The other end of the threaded rod 8 is threadedly connected to the inside of one end of the rotating rod 3. A clamping plate 12 is located inside the fixed frame 1, and a movable plate 13 is located outside the fixed frame 1.
[0022] One end of the connecting block 2 is fixedly connected to the clamping plate 12, and the other end of the connecting block 2 is movably connected to the movable plate 13. One end of the movable plate 13 is fixedly connected to the handwheel 14. Two bidirectional threaded rods 15 are provided on both sides of the connecting block 2. One end of the two bidirectional threaded rods 15 is threadedly connected to both ends of the clamping plate 12, and the other end of the two bidirectional threaded rods 15 is threadedly connected to both ends of the movable plate 13.
[0023] When it is necessary to limit and correct the product material on the surface of the conveyor belt 4, the clamping plate 12 and the movable plate 13 are placed on the top two sides of the fixed frame 1 respectively, and then the two handwheels 14 are rotated at the same time. The rotation of the two handwheels 14 will drive the two bidirectional threaded rods 15 to rotate respectively. The two bidirectional threaded rods 15 will simultaneously drive the movable plate 13 to move, so that the movable plate 13 moves along the outside of the connecting block 2, thereby moving closer to the clamping plate 12 through the movable plate 13, so that the movable plate 13 and the clamping plate 12 are clamped and fixed on the top of the fixed frame 1.
[0024] Secondly, depending on the size of the product material, when it is necessary to adjust the angle of the rotating rod 3, one end of the rotating rod 3 rotates around one end of the connecting block 2. When the rotating rod 3 rotates to the appropriate position, the turntable 7 is rotated, and the threaded rod 8 is driven to rotate through the turntable 7, so that the threaded rod 8 rotates inside the connecting block 2 and the rotating rod 3. The rotating rod 3 is fixed to one end of the connecting block 2 through the threaded connection.
[0025] Furthermore, one end of the connecting block 2 is fixedly connected to the limiting block 6, which is located on the outside of the movable plate 13. By setting the limiting block 6, the movement of the movable plate 13 is restricted, preventing the movable plate 13 from detaching from the outside of the connecting block 2.
[0026] Furthermore, a second limiting ring 16 is fixedly connected to one end of the bidirectional threaded rod 15. The second limiting ring 16 is located on one side of the clamping plate 12. By setting the second limiting ring 16, the movement of the bidirectional threaded rod 15 is restricted, preventing the bidirectional threaded rod 15 from leaving the interior of the clamping plate 12.
[0027] Furthermore, both ends of the threaded rod 8 are threaded in the same direction, the middle part of the threaded rod 8 is machined into a smooth cylinder, one end of the connecting block 2 is machined into a first threaded groove 10, the upper half of the first threaded groove 10 is threaded, the lower half of the first threaded groove 10 is machined into a smooth inner wall, the top of the threaded rod 8 is threadedly connected to the upper half of the inner wall of the first threaded groove 10, one end of the rotating rod 3 is machined into a second threaded groove 11, the lower half of the second threaded groove 11 is threaded, the upper half of the second threaded groove 11 is machined into a smooth inner wall, and the bottom of the threaded rod 8 is threadedly connected to the lower half of the inner wall of the second threaded groove 11.
[0028] When it is necessary to loosen the rotating rod 3 from the connecting block 2, the turntable 7 is rotated, causing the threaded rod 8 to rotate downward inside the rotating rod 3, so that the thread at the bottom end of the threaded rod 8 rotates inside the second thread groove 11, so that the thread at the bottom end of the threaded rod 8 is disengaged from the thread inside the second thread groove 11, and the smooth cylinder in the middle of the threaded rod 8 is located inside the second thread groove 11, thereby allowing one end of the rotating rod 3 to rotate around one end of the connecting block 2.
[0029] Secondly, when it is necessary to fix the rotating rod 3 to one end of the connecting block 2, rotate the turntable 7 so that the threaded rod 8 moves upward along the inside of the first threaded groove 10 and the second threaded groove 11. At the same time, the bottom end of the threaded rod 8 is threadedly connected to the lower half of the inside of the second threaded groove 11, thereby fixing the rotating rod 3 to one end of the connecting block 2.
[0030] Furthermore, a first limiting ring 9 is fixedly connected to the bottom of the threaded rod 8. The first limiting ring 9 is located at the bottom of the rotating rod 3. By setting the first limiting ring 9, the threaded rod 8 is prevented from dislodging from the interior of the second threaded groove 11.
[0031] Working principle: By simultaneously rotating two handwheels 14, the rotation of the two handwheels 14 will drive the two bidirectional threaded rods 15 to rotate respectively. The bidirectional threaded rods 15 will drive the movable plate 13 to move closer to the clamping plate 12 along the outside of the connecting block 2, so that the movable plate 13 and the clamping plate 12 are clamped and fixed on the top of the fixed frame 1. Then, the rotating rod 3 is rotated around one end of the connecting block 2. When fixed, the turntable 7 is rotated, so that the threaded rod 8 rotates inside the connecting block 2 and the rotating rod 3. The rotating rod 3 is fixed to one end of the connecting block 2 through the thread, thereby adjusting the angle of the rotating rod 3, which facilitates the limit correction of the product material on the surface of the conveyor belt 4.
[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
