Spacing between described two demagnetization rollers 1,7 can adjust, and when demagnetization roller 1,7 does not touch conveyer belt 5, the distance between two demagnetization rollers 1,7 must be able to appropriately adjust, to improve erasing field intensity.
Steel wire lining conveyor belt 5 jitter in running is very large, and in shake, steel wire lining conveyor belt 5 can affect erasure effect through in the middle of two demagnetization rollers 1,7.So two demagnetization roller groups 12 of the present invention must be installed on end slewing rollers 11 place of conveyer belt, only have the most steady herein; Two folder plain-barreled rolls 13 are housed in two demagnetization roller fronts simultaneously, and conveyer belt 5 enters in the middle of two demagnetization rollers 12, see Fig. 2 after being flattened by folder plain-barreled roll 13.
