[0020] 2、The silicon oil is attached on the wiping member, and the residual adhesive on the cutting knife can be wiped off after the wiping member wipes the cutting knife, so that the cutting knife is not replaced due to the residual adhesive on the cutting knife, thereby prolonging the service life of the cutting knife.

[0021] 3、The third fixed plate is provided with a plurality of first through holes penetrating the third fixed plate up and down, the first through holes are the same as the second fixed part, and the wiping member is fixed with the third fixed plate through the second fixed part. The silicon oil can flow into the wiping member through the first through holes by adding the silicon oil in the first through holes, so that the purpose of adding the silicon oil to the wiping member is achieved.

[0022] 4、The second fixed plate is provided with a containing groove, and the containing groove is located below one side of the wiping member. When the silicon oil on the wiping member is too much, the excessive silicon oil can flow into the containing groove for collection, so that the silicon oil pollution of the machine is avoided.
