Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a chain conveyor line. Background Technology

[0002] In industrial production and logistics, chain conveyor lines are widely used for conveying various materials due to their advantages such as high load-bearing capacity and stable transmission. Existing chain conveyor lines mainly consist of a drive unit, chain, conveyor track, tensioning device, and frame. The drive unit drives the chain to circulate on the conveyor track, thereby achieving material conveying.

[0003] However, existing chain conveyor lines have relatively long conveyor chains that are prone to sagging in the middle, causing materials to collide at the start and end points, resulting in material damage and increased production costs. The tensioning mechanism of chain conveyor lines is also inconvenient to adjust. When the chain becomes loose due to long-term use, it is necessary to stop the machine and disassemble multiple parts to adjust the tensioning mechanism, which is complicated, time-consuming, and seriously affects production efficiency. Therefore, we propose a chain conveyor line. Utility Model Content

The chain support rings 11 are located below the long chain 7 and provide support for the long chain 7. A tray is placed on the top of the long chain 7. Tensioning mechanisms are provided on the outer surfaces of the drive sprocket 4 and the driven sprocket 5. By installing rotating drums on both inner walls of the top of the conveyor bracket 3 and fitting chain support rings 11 on the surface of the rotating drums, the chain support rings 11 are located below the long chain 7 and can effectively support the long chain 7, prevent the long chain 7 from sagging during operation, reduce wear between the long chain 7 and the sprocket, extend the service life of the long chain 7, and at the same time ensure the stability of material conveying and avoid material deviation and collision.

[0023] like Figure 2 , Figure 3 , Figure 4 As shown, the tensioning mechanism includes a limiting protective cover 6, a mounting plate 14, and a limiting block 17. Mounting holes 16 are provided on both sides of the limiting protective cover 6. The two ends of the driven sprocket 5's shaft are located inside the mounting holes 16. The mounting plate 14 is symmetrically welded to the outer surfaces of both sides of the conveyor bracket 3. Threaded holes are provided on the surface of the mounting plate 14. A waist-shaped hole 15 corresponding to the position of the threaded hole is provided on the surface of the limiting protective cover 6.

[0024] like Figure 1 , Figure 2 , Figure 3As shown, corner brackets 10 are evenly installed on the outer top of the conveyor support 3, and L-shaped baffles 8 are installed on the top of the corner brackets 10 by locking bolts. By setting the L-shaped baffles 8, the pallet is prevented from shifting or even falling off the conveyor support 3. The L-shaped baffles 8 are installed on the conveyor support 3 by the corner brackets 10 and locking bolts, which is convenient for disassembly and adjustment and can adapt to the conveying needs of materials of different specifications.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the drive assembly includes a geared motor 2, a drive shaft 12, and a drive sprocket.
