[0038] The double-speed chain 32 is arranged in the profile rail 20 and is wound around the driving sprocket and the driven sprocket 31. The first tooling plate 40 is arranged on the two double-speed chains 32, and the two tensioning adjustment mechanisms 60 correspond to the two driven sprockets 31 respectively. The tensioning adjustment mechanism 60 is used to adjust the distance between the driven sprocket 31 and the driving sprocket to adjust the tension of the double-speed chain 32.

[0039] The present embodiment discloses a double-speed chain conveying device, which corresponds to two double-speed chain assemblies by designing two tensioning adjustment mechanisms 60. The operator only needs to operate the tensioning adjustment mechanism 60 to adjust the distance between the driven sprocket 31 and the driving sprocket to adjust the tensioning degree of the double-speed chain 32. This not only improves the convenience of adjustment, but also improves the stability of the movement of the double-speed chain 32, and facilitates the assembly and maintenance of the double-speed chain assembly.

[0040] In one embodiment, the tension adjustment mechanism 60 includes a connection seat 61, a support shaft 62 and an operating assembly.

The operating assembly is used to drive the support shaft 62 to move or lock the support shaft 62.

[0041] Specifically, when adjusting the tension of the speed chain 32, the operator only needs to operate the operating assembly to slide the driving support shaft 62 and the driven sprocket 31 along the length direction of the profile rail 20. Since the operating assembly can lock the position of the support shaft 62 in the connecting seat 61, the spacing between the driven sprocket 31 and the driving sprocket is adjusted, thereby adjusting the tension of the speed chain 32.

[0042] In one embodiment, two support blocks 63 arranged opposite to each other are fixed to the inner side wall of the connection seat 61, and the driven sprocket 31 is arranged between the two support blocks 63.

The double-speed chain 32 includes a plurality of connected guide wheel units, and the guide wheel unit includes a guide wheel body and two support wheels, and the two support wheels are respectively arranged on both sides of the guide wheel body, and the support wheels rest on the first wear-resistant guide bar 23 or the second wear-resistant guide bar 24.

[0046] During the movement of the speed chain 32, each guide wheel unit will pass through the first channel 21 and the second channel 22. By designing the first wear-resistant guide bar 23 and the second wear-resistant guide bar 24, it can support the speed chain 32, improve the running stability of the speed chain 32, and reduce the noise during the transmission process. At the same time, it can also reduce the wear of the speed chain 32 and reduce the maintenance cost.
