When the fabric needs to be threaded, the roller shaft is first separated from the driving mechanism, and then the roller shaft limiting plate is lifted, and the transition cloth guide rollers can be easily separated. The structure is simple, easy to operate, and the threading efficiency of the transition cloth guide roller is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 This is one of the structural schematic diagrams of the transition cloth guide roller unit described in the embodiment of the utility model;

[0009] Figure 2 This is the second structural schematic diagram of the transition cloth guide roller unit described in the embodiment of the utility model. DETAILED DESCRIPTION

[0010] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0011] like Figure 1 As shown, a transition cloth guide roller unit comprises a transition cloth guide roller 1 and a lifting device 2, wherein the transition cloth guide roller 1 has a roller shaft 11, and there are three transition cloth guide rollers 1, and each of the transition cloth guide rollers 1 is arranged tangentially in sequence in the vertical direction; the lifting device 2 comprises a roller shaft limiting plate 21 symmetrically installed at both ends of the roller shaft, and the roller shaft limiting plate 21 is movably installed in a chassis (not shown) through a lifting drive mechanism 22, and the roller shaft limiting plate 21 comprises an upright limiting plate body 211, and three strip holes 212 are spaced apart from top to bottom on the limiting plate body 211, and the horizontally lowest side wall of the strip hole 212 is the strip hole. shaped hole, and both ends of each roller shaft 11 are respectively provided with corresponding strip holes 212 and connected with a driving mechanism (not shown) for driving the transition cloth guide roller 1 to rotate; the distance between the roller shaft 11 of the transition cloth guide roller 1 located at the top layer and the bottom wall 2121 of the strip hole where the roller shaft 11 is located is A, the distance between the roller shaft 11 of the transition cloth guide roller 1 located in the middle and the bottom wall 2121 of the strip hole where the roller shaft 11 is located is B, and the distance between the roller shaft 11 of the transition cloth guide roller 1 located at the bottom layer and the bottom wall 2121 of the strip hole where the roller shaft 11 is located is C, and A<B<C.
