The utility model provides a kind of Rolling blackboard avoiding dust from flying, comprise shell, the inside of described shell is provided with rolling writing screen, described rolling writing screen comprises driving shaft, the first drive motors and driven shaft, driving shaft is connected with the first drive motors, described driven shaft is provided with at least one for tightening the spring of rolling writing screen, and the inside of described rolling writing screen is also provided with gripper shoe; The inside of described shell is also provided with wipes examination axle and the second drive motors, wipes examination axle and is connected with the second drive motors, and wiping examination axle, the second drive motors are all positioned at the outside of rolling writing screen.
On the basis of technique scheme, described wiping tries the below that axle is positioned at enclosure.
On the basis of technique scheme, the inside of described shell is also provided with dust conveyer belt and the 3rd drive motors, and dust conveyer belt is connected with the 3rd drive motors, and dust conveyer belt is positioned to be wiped immediately below examination axle.
On the basis of technique scheme, the bottom part corresponding to gripper shoe of described shell has breach, is provided with dismountable dust receiver in breach.
On the basis of technique scheme, described shell is provided with the forward button for controlling driving shaft rotation direction and reversing button.
On the basis of technique scheme, described driving shaft is positioned at the top of driven shaft.
On the basis of technique scheme, described driving shaft is positioned at the below of driven shaft.
Compared with prior art, advantage of the present utility model is as follows:
(1) inside of the utility model housing is provided with and wipes examination axle, writing on rolling writing screen is trying axle through wiping, examination can be wiped by wiping examination axle to fall, when wiping examination, speech of giving lessons can be carried out simultaneously, raise the efficiency, the dust wiping test manufacture raw is isolated between shell and rolling writing screen, effectively can avoid dust from flying.
(2) the rolling writing screen in the utility model, under the drive of driving shaft, can roll clockwise and counterclockwise as required, effectively increase clipboard face, avoiding leaving when writing writing dead angle.
(3) be provided with dust conveyer belt in the utility model, wipe the dust produced when examination axle wipes examination writing and fall on dust conveyer belt, be sent in dust receiver through dust conveyer belt, dust from flying can be avoided further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Rolling blackboard avoiding dust from flying in the utility model embodiment.
Fig. 2 is the side view of Fig. 1.
Reference numeral: 1-driving shaft, 2-rolling writing screen, 3-gripper shoe, 4-spring, 5-wipes examination axle, 6-driven shaft, 7-dust conveyer belt, 8-dust receiver, 9-shell, 10-reversing button, 11-forward button.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Shown in Figure 1, the utility model embodiment provides a kind of Rolling blackboard avoiding dust from flying, comprise shell 9, the inside of shell 9 is provided with rolling writing screen 2, rolling writing screen 2 comprises driving shaft 1, first drive motors and driven shaft 6, driving shaft 1 is connected with the first drive motors, driving shaft 1 can be positioned at the top of driven shaft 6, also the below of driven shaft 6 can be positioned at, driven shaft 6 is provided with at least one for tightening the spring 4 of rolling writing screen 2, the inside of rolling writing screen 2 is also provided with gripper shoe 3, for for providing support power during handwriting on writing screen 2.The inside of shell 9 is also provided with wipes examination axle 5 and the second drive motors, wipes examination axle 5 and is connected with the second drive motors, wipes the outside that examination axle 5, second drive motors is all positioned at rolling writing screen 2, wipes the below that examination axle 5 is positioned at shell 9 inside.
The inside of shell 9 is also provided with dust conveyer belt 7 and the 3rd drive motors, and dust conveyer belt 7 is connected with the 3rd drive motors, and dust conveyer belt 7 is positioned to be wiped immediately below examination axle 5.
The bottom part corresponding to gripper shoe 3 of shell 9 has breach, is provided with dismountable dust receiver 8 in breach.Shell 9 is provided with the forward button 11 for controlling driving shaft 1 rotation direction and reversing button 10.
Working method of the present utility model is as follows:
Shown in Figure 2, when forward button 11 switches on power, driving shaft 1 rotates clockwise, thus drive rolling writing screen 2 to roll clockwise, writing on rolling writing screen 2 rises to above gripper shoe 3 and continues to show, wiping axle 5 and driving shaft 1 rotating in same direction, wipe out the writing through wiping axle 5, the dust produced in wiping process is fallen on dust conveyer belt 7, is sent in dust receiver 8 through dust conveyer belt 7.
