[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please refer to the following: Figures 1-6The material guiding device for the belt conveyor includes: two frames 1, with two drive rollers 2 rotatably mounted on the two frames 1. A common conveyor belt 3 is fitted onto the two drive rollers 2. This conveying mechanism, consisting of the drive rollers 2 and the conveyor belt 3, is a common type of conveying system on the market. It is powered by a motor and drives the drive rollers 2 to rotate via a synchronous pulley and synchronous belt, as clearly shown in the diagram. Two guide plates 4 are located above the conveyor belt 3. The distance between the guide plates 4 and the conveyor belt 3 is small to accommodate the conveying of small materials. A first open support 5 and a second open support 6 are located above the two guide plates 4. Two open brackets 10, both with their openings facing downwards, are mounted on the first open bracket 5. A first bidirectional screw 6 is rotatably installed inside the first open bracket 5, and a first servo motor is fixedly installed on one side of the outer wall of the first open bracket 5. The output shaft of the first servo motor is fixedly connected to one end of the first bidirectional screw 6. Two pitch adjustment plates 7 are threaded onto the first bidirectional screw 6, and a first slide bar is fixedly installed inside the first open bracket 5. The first slide bar passes through the two pitch adjustment plates 7 and is slidably connected to the two pitch adjustment plates 7. A first hinge seat 8 is fixedly installed on the side of the two pitch adjustment plates 7 that is close to each other. A rotating block 9 is hinged to each of the two first hinge seats 8. The two rotating blocks 9 are close to each other. The nearest side is fixedly connected to two guide plates 4. The guide plates 4 can rotate around the hinge axis between the first hinge seat 8 and the rotating block 9. A second bidirectional screw 11 is rotatably installed inside the second open bracket 10. A second servo motor is fixedly installed on the outer wall of one side of the second open bracket 10, and its output shaft is fixedly connected to one end of the second bidirectional screw 11. Two angle adjustment plates 12 are threaded onto the second bidirectional screw 11. A second slide bar is fixedly installed inside the second open bracket 10. The second slide bar passes through the two angle adjustment plates 12 and is slidably connected to the two angle adjustment plates 12. The two angle adjustment plates 12 are close to each other. Guide rods 15 are fixedly installed on one side of each of the two guide plates 4. Second hinge seats 13 are slidably installed on the opposite sides of the two guide plates 4. Hollow sleeves 14 are hinged to the two second hinge seats 13. The ends of the two guide rods 15 that are close to each other extend into the two hollow sleeves 14 and contact the inner walls of the corresponding hollow sleeves 14. In addition, first fastening bolts 16 are threaded on the top of the two hollow sleeves 14. The bottom ends of the two first fastening bolts 16 abut against the two guide rods 15 respectively. In this way, the two angle adjustment plates 12 can be moved closer to each other by rotating the second bidirectional screw 11, thereby changing the angle of the guide plate 4.
[0024] In the above method, in order to temporarily position the guide plates 4 with the first hinge seat 8 when adjusting the distance between the two guide plates 4, arc-shaped fixing strips 17 are fixedly installed on both distance adjustment plates 7. The two arc-shaped fixing strips 17 are respectively located above the two first hinge seats 8. Both arc-shaped fixing strips 17 have annular grooves 18. The tops of the two rotating blocks 9 are threaded with second fastening bolts 19. The two second fastening bolts 19 pass through the two annular grooves 18 respectively, and the screw heads of the two second fastening bolts 19 are respectively located above the two arc-shaped fixing strips 17. By rotating the second fastening bolts 19, their screw heads are tightly pressed against the tops of the arc-shaped fixing strips 17, thereby temporarily locking the first hinge seat 8 and the rotating block 9, ensuring the stability of the two guide plates 4 when adjusting the distance.
[0025] In this method, in order to achieve a stable installation of the first open support 5 and the second open support 10, the same stabilizing frame 20 is fixedly installed on the side of the two frames 1 that are far apart from each other. Two connecting beams 21 are fixedly installed at the bottom of the stabilizing frame 20, and the tops of the first open support 5 and the second open support 10 are fixedly connected to the bottoms of the two connecting beams 21.
[0026] In this method, in order to ensure that the second hinge seat 13 has a sliding space on the guide plate 4 and to ensure smooth angle adjustment, a groove is provided on the side of the two guide plates 4 that is far apart from each other. A slide rod is slidably installed in each of the two grooves, and a slider is slidably installed on each of the two slide rods. The side of the two sliders that is far apart from each other is fixedly connected to the two second hinge seats 13 respectively.
[0027] The working principle of the material guiding device for belt conveyors provided by this utility model is as follows:
[0028] Before guiding the material, the distance and angle of the two guide plates 4 are adjusted. During adjustment, the second servo motor is started in the forward direction, and its output shaft drives the second bidirectional screw 11 to rotate. The two angle adjustment plates 12 move closer to each other. At this time, under the push of the guide rod 15 and the hollow sleeve 14, the two guide plates 4 rotate around the hinge axis of the two rotating blocks 9. At this time, the two guide plates 4 gradually tilt until they tilt to the required angle range. Then, the second servo motor is turned off. Thus, the angle adjustment of the guide plates 4 is completed.
[0029] Then, tighten the two first fastening bolts 16 to separate them from the corresponding guide rods 15, thus removing the external force holding the guide rods 15 and the hollow sleeve 14. Then, tighten the two second fastening bolts 19 so that the screw heads of the two second fastening bolts 19 are in tight contact with the two arc-shaped fixing strips 17, temporarily fixing the first hinge seat 8 and the rotating block 9 together. Then, start the first servo motor in the forward direction, and its output shaft drives the first bidirectional screw 6 to rotate. The two spacing adjustment plates 7 move closer to each other. At this time, under the push of the first hinge seat 8 and the rotating block 9, the spacing between the two guide plates 4 begins to change until the spacing between them reaches the required range. Then, turn off the first servo motor and retighten the first fastening bolts 16 so that they are in contact with the guide rods 15. This completes the spacing adjustment of the guide plates 4. Then, pour the material onto the conveyor belt 3 for conveying.
[0030] Compared with related technologies, the material guiding device for belt conveyors provided by this utility model has the following advantages:
[0031] This utility model provides a material guiding device for a belt conveyor. Through the first hinge seat 8 and the rotating block 9, and the second hinge seat 13 slidably mounted on the guide plate 4, the rotation of the second bidirectional screw 11 can drive the two angle adjustment plates 12 to move, thereby gradually changing the angle between the two guide plates 4. Furthermore, by utilizing the rotation of the first bidirectional screw 6, the two spacing adjustment plates 7 can be moved, thereby adjusting the spacing between the two guide plates 4. Thus, the angle and spacing of the two guide plates 4 can be adaptively adjusted according to actual needs to meet basic working requirements.
