The invention discloses a portable anti-pollution plastic spraying device for mathematics teaching aids, which comprises a base, a groove is opened on the top of the base, and a moving mechanism is slidably connected inside the groove, and the moving mechanism includes a notch and a screw rod. , belt, driving motor, connecting block, movable plate, rollers and rolling grooves, the inside of the groove is symmetrically provided with notches, and the inside of the two said notches is symmetrically rotated and connected with a screw rod, and the screw rod runs through one end of the base. The structure of the invention is scientific and reasonable, and it is safe and convenient to use. A moving mechanism is set up to drive the screw rod to rotate through the driving motor, and at the same time, the two screw rods can be rotated synchronously through the belt drive, which is convenient for the two screw rods to move to push the movable plate to move and pass through the groove. The mouth and the connecting block cooperate to ensure the stability of the movable plate when moving, avoiding deviation and affecting the spraying effect of teaching aids. In addition, the friction between the connecting block and the notch is reduced through the cooperation of the roller and the rolling groove.
Description
technical field [0001] The invention relates to the technical field of mathematics teaching aids, in particular to a portable anti-pollution plastic spraying device for mathematics teaching aids. Background technique [0002] Mathematics teaching aids are a tool used for teachers to teach. While reducing the teaching burden of teachers, it is more convenient for students to understand and improve the quality of teaching. Spray plastic on the surface, thereby improving the service life of mathematics teaching aids and reducing wear and tear; [0003] However, the existing plastic spraying device cannot move the mathematical teaching aid conveniently when the mathematical teaching aid is sprayed. At the same time, because of the friction, the device will shift when moving, which will affect the stability of the mathematical teaching aid. Mathematics teaching aids are offset, which affects the spraying in the later stage. Therefore, in order to avoid the above-mentioned techni...
