Description

technical field [0001] The invention relates to the technical field of chalk processing, in particular to a chalk film pasting machine. Background technique [0002] Teachers often need to use chalk to write and draw on the blackboard to explain. In a class of 45 to 50 minutes, they often touch the chalk directly with their hands. When the class is over, they often leave a layer of white chalk dust on their hands. When writing on the blackboard, the hands are covered with chalk dust for a long time, which has a certain impact on the body; and when the chalk is not in use, it will also fall off and have chalk dust, which will affect the surrounding environment. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a chalk film sticking machine with simple structure, easy operation and high production efficiency. [0004] To achieve the above object, the specific scheme of the present invention is...
