Abstract

The invention discloses a teaching blackboard which comprises a blackboard body. A main open groove is formed in the left side of the blackboard body, a first rotating shaft is arranged in the main open groove, a first rotating cylinder is arranged on the outer side of the first rotating shaft, a second rotating cylinder is arranged under the first rotating cylinder, and the second rotating cylinder is in transmission connection with the first rotating cylinder through a blackboard conveying belt. A writing board is vertically arranged on the left side of the first rotating cylinder, two firstopen grooves are vertically formed in the left side face of the writing board, magnetic limiting strips are vertically arranged in the first open grooves, and a plurality of first magnets are arranged on the magnetic limiting strips at equal intervals. A second open groove is formed in the inner side face of the blackboard conveying belt, second magnets matched with the first magnets are arrangedin the second open groove at equal intervals, and the second magnets have the same magnetism as the first magnets. The writing board is located between the blackboard conveying belt and the first rotating cylinder, a first cleaning assembly is arranged on the upper portion of the right side of the blackboard conveying belt, and the first cleaning assembly comprises a cleaning roller. The blackboard conveying belt can be conveniently cleaned.

Description

technical field [0001] The invention relates to the technical field of teaching, in particular to a blackboard for teaching. Background technique [0002] The blackboard does not specifically refer to the black board surface. In the traditional sense, it is a plane that can be repeatedly written with chalk.
