For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0023] Reference Figures 1 to 5 In the embodiment of the utility model, a roller support device for a conveyor mesh belt comprises: a hollow support column 1, a fixed plate 2 is fixedly connected below the hollow support column 1, four groups of screw grooves 3 are opened above the fixed plate 2 and penetrate to the bottom, a fixed screw 4 is arranged above the screw groove 3, a sliding support column 5 is slidably connected above the hollow support column 1, and a roller support mechanism 6 is fixedly connected above the sliding support column 5;

[0024] The roller support mechanism 6 includes a fixed base 61, a spring groove 62 is provided above the fixed base 61, four groups of support springs 63 are fixedly connected to the inner side of the spring groove 62, a gasket plate 64 is fixedly connected to the upper side of the support spring 63, a limited slide groove 65 is provided on the side of the fixed base 61, a long screw 66 is fixedly connected to the inner side of the limited slide groove 65, a first limited arm 67 is provided above the limited slide groove 65, an upper plug plate 68 is fixedly connected to the side of the first limited arm 67, a second limited arm 69 is provided above the limited slide groove 65, an upper slot 610 is provided on the side of the second limited arm 69, and the first limited arm 67 and the second limited arm 69 are provided below They are all fixedly connected with a limit slider 611, and the side of the limit slider 611 is rotatably connected with a rotating ring 612. When the support spring 63 is not subjected to external force, the gasket plate 64 is partially inside the spring groove 62. When the support spring 63 is subjected to pressure, the gasket plate 64 slides inside the spring groove 62. There are two groups of limit slots 65 and long screws 66, which are symmetrically arranged on both sides of the fixed base 61. The limit slider 611 is adapted to the limit slot 65. The rotating ring 612 is provided with a thread inside and is adapted to the long screw 66. The upper slot 610 passes through the second limit arm 69, and the upper plug plate 68 is adapted to the upper slot 610.

[0025] The above scheme is adopted: for rollers of different sizes, the movable end of the roller can be placed above the gasket plate 64 first, and by continuously tightening the two sets of rotating rings 612, the first limit arm 67 and the second limit arm 69 are contracted inward, and the two sides of the roller are limited to the appropriate position. The upper plug plate 68 and the upper slot 610 above the gasket plate 64 cooperate to limit the upper part of the movable end of the roller to prevent it from being squeezed out. The support spring 63 lifts the gasket plate 64 and the roller upward. Such a design ensures the support of rollers of different sizes, and the support spring 63 can effectively absorb and alleviate the impact of the material on the roller when it falls, so that the material is more stable during transportation, and the elasticity of the support spring 63 can be adjusted according to the tension of the conveyor belt, so as to maintain the stable operation state of the conveyor belt, thereby extending their service life.

[0026] Reference Figure 1 and Figure 3A side slot 7 is provided on the side of the hollow support column 1, a rotating fixed seat 8 is fixedly connected to the side of the hollow support column 1, a gear column 9 is provided on the side of the rotating fixed seat 8, and a hand crank 10 is provided on the side of the rotating fixed seat 8. A shell 11 is fixedly connected to the side of the hollow support column 1 at the outside of the gear column 9, and an internal threaded ring 12 is embedded at the same height as the other side of the hollow support column 1 at the same position as the gear column 9. The internal threaded ring 12 is internally threaded with an extrusion screw 13. A plurality of groups of positioning holes 14 are provided on the side of the sliding support column 5, and a tooth groove 15 is provided on the side of the sliding support column 5. Two groups are provided on the rotating fixed seat 8, and the rotating shafts of the gear column 9 are rotatably connected to the two groups of rotating fixed seats 8 respectively. One group of rotating shafts of the gear column 9 penetrates the rotating fixed seat 8 and is fixedly connected to the hand crank 10. The gear column 9 is meshed with the tooth groove 15, and the internal threaded ring 12 is adapted to the extrusion screw 13. The diameter of the positioning hole 14 is slightly larger than the diameter of the extrusion screw 13.

[0027] The above scheme is adopted: the gear column 9 can be driven to rotate by shaking the hand crank 10. When the position of the roller support mechanism 6 needs to be adjusted, only the extrusion screw 13 needs to be loosened. Shaking the hand crank 10 can drive the gear column 9 to rotate, and the gear column 9 is meshed with the tooth groove 15. The sliding support column 5 is slidably connected to the hollow support column 1. When the hand crank 10 is rotated, the sliding support column 5 moves up and down accordingly, driving the height of the roller support mechanism 6 to be adjusted to a suitable position. When it needs to be fixed, only the height of the sliding support column 5 needs to be slightly adjusted up and down, and the extrusion screw 13 needs to be tightened to clamp it into the clamping hole 14 of the corresponding height. The position between the sliding support column 5 and the hollow support column 1 can be fixed, thereby fixing the height of the roller support mechanism 6.

[0028] The working principle of the utility model is as follows: for the installation of the roller, the movable end of the roller can be placed above the gasket plate 64, and the two sets of rotating rings 612 can be tightened to make the first limiting arm 67 and the second limiting arm 69 shrink inward, and move them to the appropriate position to limit the two sides of the roller. The upper plug plate 68 above the gasket plate 64 cooperates with the upper slot 610 to limit the upper side of the movable end of the roller to prevent it from being squeezed out. The support spring 63 pushes the gasket plate 64 and the roller upward. Such a design ensures the support of rollers of different sizes. When the material falls on the transport mesh belt, the support spring 63 will be subjected to the pressure from the material. These support springs 63 can effectively absorb and alleviate such impact, thereby reducing the vibration and wear of the roller and the mesh belt caused by the falling material. Such a buffering effect not only protects the equipment, but also makes the material more stable during transportation, reducing the possibility of material spilling and deviation.

[0029] When it is necessary to adjust the height of the roller support mechanism 6, it is only necessary to loosen the extrusion screw 13. Shaking the hand crank 10 can drive the gear column 9 to rotate. Because the gear column 9 is meshed with the tooth groove 15, the sliding support column 5 is slidably connected to the hollow support column 1. When the hand crank 10 is turned, the sliding support column 5 moves up and down accordingly, driving the height of the roller support mechanism 6 to be adjusted to a suitable position. When it needs to be fixed, it is only necessary to slightly adjust the height of the sliding support column 5 up and down, tighten the extrusion screw 13 to clamp it into the clamping hole 14 of the corresponding height, and the position between the sliding support column 5 and the hollow support column 1 can be fixed, thereby fixing the height of the roller support mechanism 6. This design makes height adjustment convenient and reliable.

[0030] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
