Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of blank that can auto-erasing as Figure 1-4, comprise panel 1, electric roller brush 2, original position end travel switch STa3, destination terminal travel switch STb4, motor 5, roller 6, round brush guide rail 7 and rolling wheel guide rails 8, original position end travel switch STa3 and destination terminal travel switch STb4 are Automatic-reset, motor 5 is threephase asynchronous
Round brush guide rail 7 levels are arranged on panel 1 front face top, and two travel switches are arranged on respectively round brush guide rail 7 two ends,
Electric roller brush 2 tops are provided with slippery fellow 21, and this slippery fellow 21 is slidably matched with round brush guide rail 7, and electric roller brush 2 bottoms are fixedly connected with motor 5,
In panel 1 bottom, rolling wheel guide rails 8 is installed, roller 6 is placed in rolling wheel guide rails 8 after being fixedly connected with the drive link of motor 5, in the interior rolling of rolling wheel guide rails 8,
Two travel switches, motor 5 and each switches connect by automatically controlled circuit,
Original position end original position end travel switch STa3 connects with selector switch SW.
Be provided with chute 71 in round brush guide rail 7 bottoms, the bearing of trend of chute 71 is with the identical of round brush guide rail 7 length and upwards connect round brush guide rail 7 the party, and this chute 71 coordinates with foxy 21.
On the sidewall of chute 71, be provided with the stopper slot 711 that bearing of trend is identical with chute 71 bearing of trends, on foxy 21, be provided with block 211, block 211 is slidably matched with stopper slot 711, and block 211 is for pressing two travel switches that lay respectively at round brush guide rail 7 two ends.
