| titleOfInvention | Chalk reproducing machine capable of automatically wiping blackboard |
| abstract | A chalk reproducing machine for automatically erasing a blackboard, comprising: the blackboard comprises an automatic blackboard erasing part, a shell part, a chalk smashing and stirring part and a chalk demolding part; the automatic blackboard wiping part realizes the functions of automatically wiping and collecting dust; the shell part realizes the addition of water into the stirring tank; the chalk crushing and stirring part realizes the functions of crushing and stirring the chalk head; the chalk demolding part realizes the function of demolding the remanufactured chalk; the electric cylinder A works to drive the chalk mold to move to the position below the stripping plate, so that the chalk in the round hole in the chalk mold falls into the chalk storage box, the automation of chalk manufacturing is realized, the cost is saved, and the efficiency is improved. |
