Accompanying drawing 3 is structural representations of brush roll described in accompanying drawing 1.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually, describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As Fig. 1, shown in Fig. 3, a kind of scrubbing unit brush roll automatic regulating apparatus, comprise lifting device 1, squeeze roll 2, brush roll 3 and cylinder 4, described brush roll 3 is arranged on a bearing block 31, described squeeze roll 2 is arranged on brush roll 3 tops, described squeeze roll 2 cooperatively interacts with brush roll 3 and rotates round about, for steel strip surface is cleaned with water, steel band passes from squeeze roll 2 and the centre of brush roll 3, 3 pairs of steel strip surface of brush roll are scrubbed, lifting device 1 is connected with brush roll 3, cylinder 4 is arranged on bearing block 31 bottoms and is connected with bearing block 31, cylinder 4 can be by upwards top or decline of bearing block 31, utilize cylinder 4 fast by brush roll 3 location.
Described lifting device 1 comprises lifting motor 11, screw mandrel 12 and block 13, lifting device 1 is for accurately locating the position of brush roll 3, rear steel strip surface quality is scrubbed in assurance, described lifting motor 11 is positioned at the top of screw mandrel 12, and block 13 is connected with the bottom of screw mandrel 12, and block 13 is L-type, block 13 one end stretch in bearing block 31, affixed at above-below direction with bearing block 31, stop nut 311 is installed on bearing block 31, the end of block 3 is connected with stop nut 311 is intermeshing.
As shown in Figure 2, described screw mandrel 12 is provided with external screw thread 121, block 13 comprises a joint pin 131 and a baffle plate 132, baffle plate 132 is vertically mounted on joint pin 131 by a ring flange 133, joint pin 131 tops are hollow structure, in hollow structure, be provided with the internal thread (scheming not shown) matching with the external screw thread 121 of described screw mandrel 12, screw mandrel 12 is threaded connection with joint pin 131, by lifting motor 11, drive screw mandrel 12 rotations, by screw mandrel 12, rotarily actuate joint pin 131 and drive block 13 to move up and down.
