The straightening plate 101 is a main mounting member and a supporting member of the passive straightening wheel assembly 100, in this embodiment, the straightening plate 101 is a rectangular plate, and the fixed driven wheel 102 and the sliding driven wheel 103 are both located on the straightening plate 101.
The fixed driven wheel 102 is fixedly provided on the straightening plate 101. The fixed connection means that the relative position of the fixed driven wheel 102 and the straightening plate 101 is kept unchanged. Optionally, a fixed driven wheel 102 is rotatably connected to the straightening plate 101. A plurality of fixed driven wheels 102 are provided at intervals in a first direction, i.e., a direction a shown in the drawing, on the straightening plate 101 as shown in fig. 1.
