The invention discloses an automatic ash removal device for a projector for teaching. The automatic ash removal device comprises a curtain box, a first rotating roller and a second rotating roller. Two symmetrically-distributed fixed plates are fixed to the lower portion of the curtain box through bolts and threads. A first rotating shaft and a second rotating shaft which are located on the same horizontal line are in through connection to the middles of the two fixed plates. The first rotating roller is fixed to the outer surface wall of the first rotating shaft in a sleeving manner. The second rotating roller is fixed to the outer surface wall of the second rotating shaft in a sleeving manner. The outer surface walls of the second rotating roller and the first rotating roller are each fixedly sleeved with mucilage glue, and a curtain is movably clamped between the second rotating roller and the first rotating roller. The first rotating roller and the second rotating roller of the automatic ash removal device are each fixedly sleeved with the corresponding mucilage glue; when the curtain moves, the mucilage glue can remove all dust on the two walls of the curtain in a pasting manner, and the number of times of daily maintenance can be reduced; the cleanliness of the curtain can be improved, and good conditions can be provided for teaching; the mucilage glue can be cleaned in the long-time use process, the dust adhesion capacity of the mucilage glue can be guaranteed, and repeated use can be achieved.
Description
technical field [0001] The invention relates to the technical field of the teaching industry, in particular to an automatic dust cleaning device for a teaching projector. Background technique [0002] A projector is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a screen. It can be used for profile measurement with transmitted light, and it can also be used to measure the surface shape of impermeable holes and observe the surface of parts. Projectors are currently widely used in homes, offices, schools and entertainment places. According to different working methods, there are CRT, LCD, DLP, etc. Different types, but existing teaching projectors have some deficiencies during use. [0003] 1. During the long-term use of the projector, a lot of dust will fall on the screen, which will affect the performance of the screen. [0004] 2. During the lifting process of the projector, the screen will wrinkle, which will af...
