In the introducing section 6211, since the roller of the hanger needs to be introduced, the roller has a certain size, so that a wider distance needs to be reserved before the roller is not buckled into the plate link, and the distance between the introducing section 6211 and the link groove 611 is set wider.

A pair of supporting convex edges 64111 corresponding to the hanging edges 416 are symmetrically arranged on the notch of the guide groove 6411 by taking the central line of the notch as an axis, and the hanging edges 416 are erected on the supporting convex edges 64111 to realize that the plate chain is hung in the guide groove 6411; since the bent guide unit is disposed at the ends of the plate chain guide member 61 and the roller guide member 62, the hanger is received by the plate chain 41 at the plate chain guide member 61, in order to avoid not being stable enough at the moment when the hanger is received, and causing falling in the subsequent transportation process, a blocking edge 6422 for blocking the outside of the bottom of the inner wheel disc 5211b is disposed outside the receiving groove 6421, the blocking edge 6422 is disposed so as to limit the inner wheel disc 5211b in the receiving groove 6421, and better prevent the hanger from falling, and as shown in fig. 25, the top of the blocking edge 6422 is aligned with the inner limit cam 5213b of the roller, if the inner wheel disc 5211b has a tendency to fall down, the blocking edge 6422 will exert an upward force on the inner limit cam 5213b, and instead, the inner wheel disc 5211b can be pushed upward to be better embedded in the bearing link of the plate chain, so as to stabilize the connection between the plate chain and the hanger. In order to avoid interference with the blocking edge 6422 during operation of the plate chain, the blocking edge 6422 is designed to be narrow, and an avoiding step 6423 for avoiding the plate chain 41 is formed outside the blocking edge 6422.
