The appearance wall of first rotating shaft is fixed with the first transfer roller, and the appearance wall of second shaft is fixed with the second transfer roller, and described
The appearance wall of two transfer rollers and the first transfer roller is fixed with viscose glue, and activity accompanies curtain between the second transfer roller and the first transfer roller,
The curtain active volume is in the inside of curtain case, and the bottom end of curtain is fixed and accompanies weight linear meter, solid between two pieces of fixed plates
Surely it is inserted with translucent cover, the translucent cover covers on the outside of the first transfer roller and the second transfer roller.
Preferably, the curtain runs through translucent cover by mouth slot, and the mouth slot is opened on translucent cover, and the setting of mouth slot exists
The junction of first transfer roller and the second transfer roller.
Preferably, the thickness of the curtain and the thickness of viscose glue are equal, and the thickness of curtain is the first transfer roller
With the one third of the second transfer roller spacing dimension.
Preferably, the viscose glue is made of thermoplastic rubber material.
Preferably, the curtain case is fixed on by bolt thread on metope.
Compared with prior art, the beneficial effects of the invention are as follows：
1, the first transfer roller and the second transfer roller with rotating function of the invention by being arranged below projecting apparatus, and curtain is pressed from both sides
Among the first transfer roller and the second transfer roller, when curtain lifts, the first transfer roller and the second transfer roller ensure that the movement of curtain is smooth
Property, be not in buckling phenomena, meet teaching demand.
2, it is fixed with viscose glue on the first transfer roller and the second transfer roller of the invention, when curtain moves, viscose glue can incite somebody to action
Under the dust of two wall of curtain all glues, the daily maintenance number of curtain is reduced, moreover it is possible to which the cleaning for improving curtain provides for teaching
Good condition, and viscose glue can be cleaned during long-time use, ensure the viscous grey ability of viscose glue, it is repeatable to make
With.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of teaching projecting apparatus automatic ash removing device, packet
Include curtain case 1, the first transfer roller 2 and the second transfer roller 3, the lower section of the curtain case 1 is fixed with symmetrical by bolt thread
Two fixed plates 23, the intermediate transit of two fixed plates 23, which has, locates first rotating shaft 21 in the same horizontal line and second turn
The appearance wall of axis 31, the first rotating shaft 21 is fixed with the first transfer roller 2, and the appearance wall of second shaft 31 is fixed with
The appearance wall of two transfer rollers 3, second transfer roller, 3 and first transfer roller 2 is fixed with viscose glue 22, and the second transfer roller 3 and first turn
Activity accompanies curtain 11 between roller 2, and 11 active volume of the curtain is in the inside of curtain case 1, and the bottom end of curtain 11 is fixed and accompanied
Weight linear meter 12, fixed between two pieces of fixed plates 23 to be inserted with translucent cover 231, the translucent cover 231 covers on the first transfer roller 2 and the
The outside of two transfer rollers 3.
The curtain 11 runs through translucent cover 231 by mouth slot 232, and the mouth slot 232 is opened on translucent cover 231, and mouth
Slot 232 is arranged in the junction of the first transfer roller 2 and the second transfer roller 3, and the translucent cover 231, which primarily serves, prevents dust from falling in viscose glue
