Description

Technical Field

[0001] The utility model relates to the technical field of color sorters, in particular to a conveyor belt mechanism of a color sorter. Background Art

[0002] A color sorter is a device that uses photoelectric detection technology to automatically sort out heterogeneous impurities in materials based on the differences in the optical properties of the materials. The color sorter is equipped with a conveyor belt mechanism that uses a belt to transport materials. The belt bed assembly in existing crawler color sorters is generally designed as a whole. Every time the belt is replaced, the entire belt bed assembly including rollers, connecting brackets, etc. needs to be removed. This design is not suitable for the sorting of medium and large-sized materials, such as medium and large ores. Due to the large mass and volume of such materials, thickened belts need to be used for transportation, and the diameters of the front and rear rollers of the belt bed assembly also need to be increased to avoid belt breakage. However, the disassembly and installation of this type of belt bed assembly as a whole is very difficult, so there is a need for a color sorter conveyor belt mechanism that can transport medium and large-sized materials and facilitate the disassembly and assembly of the belt.

[0003] The patent entitled "New concealed steel buckle structure and conveyor belt for belt joints" (CN217497423U) discloses a technical solution, including a surface rubber layer, a tension cloth layer and a concealed steel buckle structure. The steel buckle joint conveyor belt of this solution is easy to disassemble and assemble, but it is difficult to meet the load-bearing requirements for large-sized materials. Utility Model Content

[0004] The utility model aims to provide a conveyor belt mechanism for a color sorter, which can simultaneously meet the requirements of load-bearing strength and convenient disassembly and assembly of the conveyor belt.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a conveyor belt mechanism of a color sorter, an upstream roller and a downstream roller with parallel roller cores are rotatably arranged on a frame, the conveyor belt is sleeved on the upstream roller and the downstream roller to form a belt transmission mechanism, the conveyor belt includes at least two conveyor belt units, the belt surface edges of adjacent conveyor belt units in the conveying direction are detachably connected by steel buckle joints, a load-bearing plate and a support roller are arranged close to or under the belt surface of the conveyor belt supporting the material, the load-bearing plate is fixedly connected to the frame and its side edge is arranged adjacent to the roller surface of the upstream roller, and the support roller is rotatably arranged on the frame and is located between the load-bearing plate and the downstream roller.

[0006] The utility model mainly uses a steel buckle joint conveyor belt to replace the traditional integral conveyor belt, and arranges a bearing plate adjacent to the upstream roller under the belt surface of the conveyor belt that supports the material. The steel buckle joint conveyor belt is easy to disassemble and assemble, and there is no need to disassemble the upstream and downstream rollers and other components when replacing; a support roller is arranged between the bearing plate and the downstream roller to support the upper belt surface, and the bearing plate provides support when the material is thrown to the upstream of the conveyor belt, thereby reducing the damage to the conveyor belt caused by the material being thrown, and avoiding the tearing of the steel buckle joint conveyor belt.

[0012] See also Figure 1-5 The color sorter conveyor belt mechanism shown in the figure has an upstream roller 11 and a downstream roller 12 with parallel roller cores rotatably arranged on the frame 1, and the conveyor belt 10 is sleeved on the upstream roller 11 and the downstream roller 12 to form a belt transmission mechanism, the conveyor belt 10 includes at least two conveyor belt units 101, and the belt surface edges of adjacent conveyor belt units 101 in the conveying direction are detachably connected by steel buckle joints 102, and a load-bearing plate 20 and a support roller 30 are arranged close to or adjacent to the belt surface of the conveyor belt 10 that supports the material. The load-bearing plate 20 is fixedly connected to the frame 1 and its side edge is arranged adjacent to the roller surface of the upstream roller 11, and the support roller 30 is rotatably arranged on the frame 1 and is located between the load-bearing plate 20 and the downstream roller 12.

[0013] In the above scheme, when the color sorter is sorting large-sized materials such as medium and large ores, the wear of the conveyor belt 10 will also accelerate due to the large mass of the materials. Therefore, a new conveyor belt 10 needs to be replaced every once in a while, and the conveyor belt 10 with a steel buckle joint 102 at the end of the belt surface has the advantage of easy disassembly and assembly, but the steel buckle joint conveyor belt 10 has a greater risk of breaking than the traditional one-piece conveyor belt. When conveying materials, the upper belt surface of the conveyor belt 10 adjacent to the upstream roller 11 needs to bear the impact force of the falling materials. Therefore, a load-bearing plate 20 is arranged under the belt surface close to or adjacent to provide support for the conveyor belt 10, which can effectively prevent the conveyor belt 10 from breaking due to the impact of the materials. Since the conveyor belt 10 has a certain elasticity, a support roller 30 is arranged between the load-bearing plate 20 and the downstream roller 12 to support the upper belt surface to reduce the belt surface depression caused by the pressure of the materials on the conveyor belt 10.

[0014] In order to minimize the impact of falling materials on the conveyor belt 10, the plate surface of the load-bearing plate 20 is parallel to the belt surface of the conveyor belt 10 supporting the materials.

[0015] In order to allow the support roller 30 to provide more uniform support for the conveyor belt 10 , the roller core of the support roller 30 is parallel to the roller cores of the upstream roller 11 and the downstream roller 12 , and the support rollers 30 are arranged at equal intervals between the load-bearing plate 20 and the downstream roller 12 .

[0016] Preferably, the two ends of the roller shaft 31 of the support roller 30 are connected with a pin shaft 32 with a vertical axis, the upper end of the pin shaft 32 is inserted and matched with the end of the roller shaft 31, the lower end of the pin shaft 32 is fixed to the frame 1 or inserted into the corresponding limit hole of the frame 1, and a spring 33 is sleeved on the outer wall of the pin shaft 32, the upper end of the spring 33 is in contact with the axial end of the roller shaft 31, and the lower end of the spring 33 is in contact with the frame 1. Figure 3 , Figure 4 As shown, in the above scheme, the support roller 30 can float slightly in the vertical direction with the cooperation of the pin shaft 32 and the spring 33. When the material with a larger mass passes through the belt surface of the conveyor belt 10 near the support roller 30, the support roller 30 compresses the spring 33 and moves slightly downward, and the material also moves slightly downward. This design can make the material conveying path smoother when it is conveyed from the belt surface between the support rollers 30 to the downstream support roller 30.

[0017] In order to prevent the conveyor belt 10 from deflecting when the belt surface is working, Figure 3 , Figure 5As shown, the side of the conveyor belt 10 has an auxiliary roller 40 which is rotatably arranged on the frame 1 and has a vertical core. The surface of the auxiliary roller 40 is arranged adjacent to the side edge of the conveyor belt 10, and the surface of the auxiliary roller 40 is adjacent to the ends of the upstream roller 11 and / or the downstream roller 12. In the above scheme, the surface of the conveyor belt 10 for conveying large-sized materials is thicker. Therefore, when the conveyor belt 10 is offset due to the impact of the material, the surface of the auxiliary roller 40 directly contacts the side of the conveyor belt 10, limiting the conveyor belt 10 in the conveying area to maintain a normal working state.

[0018] Preferably, an auxiliary plate 50 fixedly connected to the frame 1 is arranged close to or adjacent to the belt surface of the conveyor belt 10 supporting the material, and the side edge of the auxiliary plate 50 is arranged adjacent to the roller surface of the downstream roller 12. The upstream roller 11 in this solution is a power roller, and the downstream roller 12 is a driven roller. One end of the upstream roller 11 is connected to a motor, and the conveyor belt 10 is driven by the friction between the roller surface and the belt surface. The arrangement of the auxiliary plate 50 can support the upper belt surface of the conveyor belt 10 adjacent to the downstream roller 12, so that the belt surface at this location is flush with the top of the downstream roller 12, ensuring the smoothness of the material conveyed to the downstream roller 12, and avoiding the material from impacting the downstream roller 12.

[0019] In order to reduce the fall of the lower belt surface of the conveyor belt 10 due to its own weight, Figure 5 As shown, an auxiliary roller 60 is arranged below the lower belt surface of the conveyor belt 10 , and the roller core of the auxiliary roller 60 is parallel to the roller core of the support roller 30 and is rotatably arranged on the frame 1 .
