[0025] The motor transmits power to the plate chain drive shaft 2 through the input shaft 1, the first plate chain sprocket 3, the second plate chain sprocket 4 and the roller chain 5. The plate chain drive shaft 2 then transports the plate stack through the first plate chain sprocket 6, the second plate chain sprocket 7 and the plate stack transport chain 8, and tensions the chain through the pull rod tensioning mechanism 10 and the power chain tensioning mechanism 9.

[0026] Example 2

[0027] On the basis of Example 1, Figure 3 and Figure 4 As shown, the tie rod tensioning mechanism 10 includes a sprocket center shaft 15, and tie rods 14 are connected to both ends of the sprocket center shaft 15. The tie rods 14 are arranged vertically with the sprocket center shaft 15, and the second plate chain sprocket 7 is connected to the sprocket center shaft 15 through a bearing. A square hole is opened on the side of the tie rod 14, and the shapes of the two ends of the sprocket center shaft 15 match the square hole. The two ends of the sprocket center shaft 15 are respectively connected to the tie rod 14 through the square holes.

[0028] like Figure 5 and Figure 6 As shown, the power chain tensioning mechanism 9 includes a tensioning seat 12 and a welding block 20 installed on the transport platform. Two long holes 22 are provided on the tensioning seat 12 at both sides of the first pin shaft 18. Adjustment bolts 21 are installed in the long holes 22.

[0032] The chain-type plate stack transport device of the utility model has the following working process: the motor is started, and the input shaft 1 drives the plate chain driving shaft 2 to rotate through the roller chain 5, thereby driving the plate stack transport chain 8 to transmit and start transporting the plate stack; during the plate stack transmission process, if the plate stack transport chain 8 is loose due to deformation caused by force after being loaded, the plate chain tension is adjusted by the pull rod tensioning mechanism 10 to tension the plate stack transport chain 8; if the roller chain 5 is loose due to deformation caused by force after being loaded, it is adjusted by the power chain tensioning mechanism 9, that is, the position of the tensioning seat 12 is adjusted by the tensioning bolt 11, thereby adjusting the position of the tensioning sprocket 13 to adjust the chain tension, and then tensioning the roller chain 5; the plate stack transport chain 8 runs smoothly, transports the plate stack to the next stage, and completes the transportation of the plates in this section.

[0033] The chain-type plate stack transport device of the utility model has the following advantages: the motor input shaft 1 is used as the power shaft, and the plate chain drive shaft 2 is used as the plate stack transport shaft.
