Cleaning, which covers 12 and is coated on the lint that sponge cleaning covers on 12, covers 13 compositions, and motor drive interior bar 11 rotates, while in rotation
13 rotation of sponge cleaning set 12 and lint set on bar, the rotation direction of cleaning rod 1 is with the rotation direction of pressure roller 10 on the contrary, cleaning
The velocity of rotation of bar 1 can pass through the rotation speed regulating and controlling of motor；The rotating speed of interior bar 11 is more than or equal to the rotating speed of pressure roller 10, it is preferred that clear
The velocity of rotation for washing bar 1 is different from the velocity of rotation of pressure roller 10, and the moment keeps tangential forces between the two；Interior bar 11 is envelope
The hollow rod body closed, and one end of interior bar 11 is connected by conduit 2 with priming device 3, and ethyl alcohol, third can be poured into priming device 3
Ketone or other cleaning solvents；The surface of interior bar 11 is evenly equipped with multiple fluid holes 14, it is preferred that it is smaller that fluid hole 14 is set as aperture
Micropore, make cleaning solvent pass through liquid injection hole 14 be slowly injected into sponge cleaning set 12 on.
Further, the holddown spring 4 for adjusting the two contact, holddown spring 4 are equipped between interior bar 11 and pressure roller 10
It is arranged in two ends of interior bar 11, one end and the interior bar 11 of holddown spring 4 are connected, the other end and roller frame of holddown spring 4
On spring base 5 be connected, spring pressurizing unit is equipped in spring base 5, by adjustment spring pressurizing unit, makes pressure roller 10 and cleaning
Best contact is kept between bar 1.
Further, conduit 2 be equipped with control valve 21, can adjust by control valve 21 cleaned in priming device 3 it is molten
The flowing velocity of agent, moment keep sponge cleaning set 12 to be in micro- moisture state.
