Abstract

A chalk end recycling and chalk resetting device is characterized by comprising a powder sucking assembly, an adhesive assembly and a pressure assembly, wherein the powder sucking assembly comprises a blackboard eraser provided with a powder suction port, and the blackboard eraser is connected with the pressure assembly through a flexible pipeline; the adhesive assembly comprises a fixing pipeline connected with the pressure assembly, and the fixing pipeline is further provided with an air pump and a window used for adding adhesive; the pressure assembly comprises a mixing cylinder and a downward pressing element capable of being pressed into the mixing cylinder, and a heating part is arranged on the lower portion of the mixing cylinder. The chalk end recycling and chalk resetting device has the advantages that chalk powder and chalk ends can be repeatedly used, and energy conservation and environment protection are achieved.

Description

Technical field [0001] The invention belongs to a teaching appliance, and specifically relates to a recycling and resetting device for recycling chalk dust and chalk heads. Background technique [0002] Chalk is still used extensively in school teaching activities. When using a chalk eraser to erase, chalk dust will enter the air and harm the surrounding environment. Inhalation of chalk dust by teachers and students can seriously threaten their health, and many teachers suffer from lung diseases as a result. The teacher always leaves a small section of the chalk after writing, because the hand is already difficult to hold it and then use it to write. The usual way is to throw away the chalk, waste resources and pollute the environment. [0003] There is an urgent need for a technology that can effectively recycle both chalk heads and chalk dust. Summary of the invention [0004] In view of the deficiencies in the prior art, the present invention provides a recycling and resetting...
