The working principle of the embodiment of the application is as follows:

the raw material of the feeding roller 25 positioned on the rotating plate 22 bypasses the guide roller 14, then the raw material bypasses the reversing inclined rod 61 and the reversing cross rod 62 to reverse the raw material, then the raw material bypasses the tensioning roller 72 and the auxiliary guide roller 164, the raw material is pressed on the guide plate 91 under the action of the auxiliary guide roller 164, then the raw material is folded for the first time through the folding plate 92, the first pressing plate 94 is pressed on the folded raw material, the raw material reaches the horizontal pressing plate 921 to be folded for the second time, the folded raw material is pressed on the conveying belt 93 through the second pressing plate 95, the conveying motor 191 is started to drive the conveying belt 93 to move, and the conveying belt 93 drives the folded raw material to be conveyed to the next process to be processed, so that the raw material is folded; therefore, the tensioning roller 72 tensions the raw material, the probability of deviation in the raw material conveying process is reduced, and the quality of the folded raw material is improved.

When the feeding roller 25 on the rotating plate 22 needs to be replaced, the driving cylinder 322 is started to drive the supporting plate 211 and the rotating plate 22 to rotate downwards, so that the worker takes the feeding roller 25 above the rotating plate 22 down, the rotating plate 22 continues to rotate, the rotating plate 22 is in contact with the feeding roller 25 on the placing groove 34, the rotating plate 22 rotates under the action of the feeding roller 25, and after the rotating plate 22 bypasses the feeding roller 25, the rotating plate 22 rotates under the action of gravity and is pressed against the supporting plate 211; the driving cylinder 322 drives the rotating plate 22 to rotate, so that the feeding roller 25 located on the placing groove 34 is clamped and mounted on the second positioning groove 221, the feeding roller 25 moves upwards under the action of the rotating plate 22, and the rotating plate 22 drives the feeding roller 25 to rotate to a specified position above the mounting rod 13 to stop rotating.

The feeding roller 25 is placed on the first positioning groove 311, the rotating cylinder 43 is started to drive the feeding rod 31 to rotate upwards, the feeding roller 25 rolls on the upper surface of the feeding rod 31 through the second guide surface 312 under the action of gravity, then the feeding roller 25 rolls on the upper surface of the positioning block 33, finally the feeding roller 25 rolls on the positioning groove 34 through the first guide surface 35, so that the feeding of the feeding roller 25 is completed, the manual conveying of the feeding roller 25 for feeding is not needed, and when the feeding roller 25 is conveyed to the positioning groove 34 of the positioning block 33, the folding machine normally works, the time spent on replacing the feeding roller 25 is saved, the time is saved, and the folding efficiency of the folding machine is improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
