Device for cleaning chilled rolls

Abstract

In a device for cleaning chilled rolls that can keep higher cleanliness of a brush, a brush includes a rotatable cylindrical barrel including a number of suction through-holes extending from an outer periphery to inside, the barrel extending in parallel with an axis of the roll, grouped cleaning wires implanted on the outer periphery of the barrel and forming a helical bank extending from one end to the other end of the barrel for cleaning of the roll, and a dust suction port at one end of the barrel and in communication with an inner space of the barrel, the dust suction port being connected to an exhaust mechanism.

1 . A device for cleaning chilled rolls which comprises brushes each comprising a rotatable cylindrical barrel formed with a number of suction through-holes extending from an outer periphery to inside, said barrel extending in parallel with an axis of the roll, grouped cleaning wires implanted on the outer periphery of the barrel and having tips abutting on an outer periphery of the roll upon rotation of the barrel and a dust suction port at one end of said barrel and in communication with inner space of the barrel, said dust suction port being connected to an exhaust mechanism. 
     
     
         2 . A device for cleaning chilled rolls as claimed in  claim 1 , wherein the grouped cleaning wires are implanted on the outer periphery of the barrel such that the wires form a helical bank extending from an end to the other end of the barrel. 
     
     
         3 . A device for cleaning chilled rolls as claimed in  claim 1 , wherein the grouped cleaning wires are implanted on the outer periphery of the barrel such that the wires form a plurality of helical banks extending from an end to the other end of the barrel. 
     
     
         4 . A device for cleaning chilled rolls as claimed in  claim 1 , wherein the grouped cleaning wires are varied in length, diameter and/or material quality between the banks. 
     
     
         5 . A device for cleaning chilled rolls as claimed in  claim 1 , wherein portions of the brush not facing to the roll are sheathed by a cowling. 
     
     
         6 . A device for cleaning chilled rolls as claimed in  claim 4 , wherein portions of the brush not facing to the roll are sheathed by a cowling. 
     
     
         7 . A device for cleaning chilled rolls as claimed in  claim 2 , wherein the grouped cleaning wires are varied in length, diameter and/or material quality between the banks. 
     
     
         8 . A device for cleaning chilled rolls as claimed in  claim 3 , wherein the grouped cleaning wires are varied in length, diameter and/or material quality between the banks. 
     
     
         9 . A device for cleaning chilled rolls as claimed in  claim 2 , wherein portions of the brush not facing to the roll are sheathed by a cowling. 
     
     
         10 . A device for cleaning chilled rolls as claimed in  claim 3 , wherein portions of the brush not facing to the roll are sheathed by a cowling. 
     
     
         11 . A device for cleaning chilled rolls as claimed in  claim 7 , wherein portions of the brush not facing to the roll are sheathed by a cowling. 
     
     
         12 . A device for cleaning chilled rolls as claimed in  claim 8 , wherein portions of the brush not facing to the roll are sheathed by a cowling.
