Detailed description of the invention
As shown in Figure 1, this pressure adjustable automatic dust-absorbing blackboard erasing apparatus comprises blackboard 1, and blackboard frame is that hollow is arranged, and enters the passage of dust catcher as dust.The lower left corner of blackboard 1, the lower right corner and directly over centre position be provided with hinges, hinge be additional roll short slab 4, drive rod 6 is connected with additional roll short slab 4, coupled arcuation drive rod 6 is driven to swing by the swing of additional roll short slab 4, arcuation drive rod 6 has the U-shaped narrow boards 7 of certain length to be interconnected by being located at blackboard eraser upper middle position, connection is herein movable connection, thus drive rod 6 just can drive blackboard eraser 8 to swing wiping.The region shape of two the blackboard eraser wipings in the lower left corner and the lower right corner of blackboard 1 is respectively quadrant territory, and the region shape of the blackboard eraser wiping directly over it is 1/2nd circle territories.Be connected by U-shaped narrow boards 7 between blackboard eraser 8 with drive rod 6, the power transmitted by drive rod 6 is delivered evenly on blackboard eraser 8 by U-shaped narrow boards 7, makes blackboard eraser 8 uniform force.
Drive rod 6 is connected with additional roll short slab 4, the additional swing of waving short slab 4 is stirred by the round pin near worm gear circumference, side plate 5 is provided with in longitudinal both sides of additional roll short slab 4, rotating shaft 13 is installed between two side plates, drive rod 6 is connected with the side plate 5 of additional roll short slab 4 by the installing hole of on drive rod 6 by this rotating shaft 13, drive rod 6 is equipped with a compression spring 14 near the below of rotating shaft one end, ensure to have at this end of drive rod 6 to upward pressure, make drive rod 6 13 have the trend of upwards rotating around the shaft, regulate blackboard eraser to the suitable pressure of blackboard.
For ensureing that the pressure uniform of spring 14 pairs of drive rods 6 is stablized, be provided with platform at drive rod 6 and the contact site of spring, it is that spring 14 is located that additional roll quarter butt 4 is provided with location round pin.
Additional roll quarter butt 4 has a groove below the outer one end of blackboard, and the round pin be positioned near worm gear circumference is inserted in the cell, makes round pin drive additional roll short slab 4 swing thus drive the swing of drive rod 6 by the rotation of worm and wormwheel.The downside of the additional roll short slab 4 of the upper middle position of blackboard is be connected on the round pin near worm gear circumference equally, thus the semicircle realizing drive rod 6 swings.Worm and gear, by Motor Control, realizes the motion of blackboard eraser 8, is controlled the boot sequence of three motors by PLC.
Drive rod 6 is communicated with the hollow space of blackboard eraser 8 by the transition connector 9 on blackboard eraser, plays dust passage.Blackboard eraser 8 is mutually through with the hollow parts of drive rod 6 and blackboard frame, being convenient to dust is drawn in the dust catcher in the lower edge centre position of blackboard, the inner longitudinal both sides of blackboard eraser 8 are provided with the tubulose dust collecting 12 identical with blackboard eraser 8 length, these dust collectings have dust collection hole, these dust collection holes communicate with dust collection hole on hairbrush end winding support plate 11.Such dust just can arrive the hollow space at blackboard 1 edge again to the hollow space of drive rod 6 by the dust collecting of blackboard eraser, finally arrive dust catcher, complete dust suction work.
