The second, unified use multimedia teaching.This can thoroughly stop chalk ash pollution equally, but this teaching pattern is applied to abroad more.Multimedia application is really attended class and has been alleviated many burdens to teacher, and domestic classroom is typically equipped with multimedia teaching facility.But according to student, reflect, multimedia teaching exists and does not see, and inconvenience is taken notes, and does not sometimes even catch up with the situation of rhythm.So the teaching pattern of blackboard and chalk is used at home always.
The 3rd, use Full-automatic dust-free blackboard or blackboard eraser, this is also domestic student's most study.Though they are structurally each has something to recommend him, in principle, be the same substantially, be nothing but by chalk ash collection.
Produced thus high temperature disappearance pen, it is similar with common gel ink pen in nature, and after temperature reaches 60 degree, person's handwriting disappears completely, leaves no trace.In addition, this pen also has hydrolysis function, meets water natural degradation.By leather industry and apparel industry, approved at present.Two kinds of pens respectively have advantage, if but select washing to wipe, blackboard also needs to carry out heating, drying to again write.To, by washing, heating two procedures, be not so good as directly to select the erase mode of heating, one-shot forming with it.Therefore select high temperature disappearance pen.
Summary of the invention
The present invention is directed to the defect that prior art exists, a kind of good waterproof performance is provided, be difficult for reflectively, efficiency of erasing is high, the rotary auto-erasing blackboard of safety and environmental protection.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of rotary auto-erasing blackboard based on high temperature disappearance pen, comprise control motor, whirligig and heater, described whirligig comprises aluminium chassis, be positioned at the upper roller at aluminium chassis top, be positioned at the lower roller of aluminium chassis bottom, be arranged on the dermatine between upper roller and lower roller, after dermatine, approximately 3 millimeters of places are provided with liner plate, described upper roller and lower roller are symmetrical arranged up and down, described heater comprises two V-type framves that are symmetrical set, be arranged on two heating rod and pressure rollers between V-type frame, described V-type frame is arranged on lower roller top, one end of described dermatine is connected with upper roller, the other end is walked around respectively heating rod, after pressure roller, be connected with lower roller.Carrying out justifying while wiping, driven by motor V-type frame rises, and pressure roller and heating rod compress dermatine to be guaranteed that heating rod contacts dermatine all the time in erase process it is wiped totally.While stopping wiping, V-type frame declines, and heating rod is away from dermatine.
As preferably, described heating rod is positioned at the outside of described dermatine, and with the outer wall surface close contact of dermatine; Described aluminium bar is positioned at the outside of described dermatine, and contacts with the inner wall surface of dermatine.
As preferably, the back side of described dermatine is provided with liner plate, and described liner plate and aluminium chassis are connected as a single entity.The Shi Buhui that writes sink dermatine.
As preferably, described control motor is connected with V-type frame, controls the rise and fall that motor drives V-type frame.By driven by motor, it rises, declines and control elasticity.So both solved the adjusting problem of elasticity, and also avoided heating rod under the condition of high temperature, to be close to dermatine always and caused leather to burn out.
