When people need to propagate the professional skill training poster, firstly, people paste the professional skill training poster in the circulating playing mechanism 4, meanwhile, the professional skill training poster is located in the display frame 2, then people enable the automatic mechanism 5 to operate, the automatic mechanism 5 operates to drive the circulating playing mechanism 4 to operate, the professional skill training poster is intermittently and repeatedly moved, and therefore the purpose of circulating playing is achieved, when the professional skill training poster stops moving, people watching a publicity column can carefully read the professional skill training poster, after the propaganda of the professional skill training poster is finished, people enable the automatic mechanism 5 to stop operating, so that the circulating playing mechanism 4 stops moving, people replace the poster again, if the equipment is used again, and the steps are repeated.
People paste professional skill training propaganda posters on a conveyor belt 43, when the automatic mechanism 5 operates, the automatic mechanism 5 enables a straight rack 45 to repeatedly slide up and down in a first guide sleeve 44, when the straight rack 45 moves downwards, a first compression spring 46 is changed into a compression state from an initial state, the straight rack 45 is meshed with a first straight gear 47, the first straight gear 47 is a one-way gear, the straight rack 45 moves to enable the first straight gear 47 to idle, the professional skill training propaganda posters cannot move at the moment, people can carefully read the propaganda posters, when the straight rack 45 moves back to the original position upwards, the first compression spring 46 is reset from the compression state, the elastic force assists the straight rack 45 to move back to the original position, the straight rack 45 moves to enable the first straight gear 47 on the lower side to rotate, the first rotary shaft 41 on the lower side is further rotated, the roller 42 on the lower side rotates to drive the conveyor belt 43 to rotate, the roller 42 on the upper side rotates to drive the first rotary shaft 41 on the upper side to rotate, the conveyor belt 43 rotates to repeatedly move up and down, the skill training posters are repeatedly, and the effect of back and forth and back and forth is achieved, when the automatic mechanism 5 stops operating, and the propaganda posters no longer move.
After people put the professional skill training propaganda poster, open cylinder 52, cylinder 52 function can make baffle 53 move from top to bottom repeatedly, and then make spur rack 45 move from top to bottom repeatedly to make professional skill training propaganda poster intermittent type nature remove repeatedly, so reached the purpose of automatic cycle broadcast, treat the poster propaganda back that finishes, people close cylinder 52, make the propaganda poster no longer remove.
Because show frame 2 exposes in the air for a long time, can be infected with the dust, thereby need people regularly to wash it, when people wash show frame 2, people make elasticity arm-tie 65 second guide pin bushing 64 internal forward slide by hand, elasticity arm-tie 65 becomes compression state by initial condition simultaneously, elasticity arm-tie 65 removes and makes switch 63 open, the water in the water tank 62 is sprayed on show frame 2 through switch 63 because of gravity this moment, wash show frame 2 so, wait to wash the completion after, people loosen elasticity arm-tie 65, elasticity arm-tie 65 resets by compression state, make switch 63 close, the water in the water tank 62 stops to flow downwards this moment.
When the straight rack 45 moves downwards, the straight rack 45 enables the first straight gear 47 to rotate, the first straight gear 47 is meshed with the second straight gear 76, the first straight gear 47 rotates to drive the second straight gear 76 to rotate, then the transmission assembly 75 rotates, the roller 73 cannot rotate because the transmission wheel on the middle side and the lower side of the transmission assembly 75 is a one-way transmission wheel, when the straight rack 45 moves upwards, the first straight gear 47 rotates reversely, the transmission assembly 75 rotates reversely, the roller 73 rotates and winds the rope 77, the movable brush 72 slides downwards on the display frame 2, the elastic assembly 71 is changed from an initial state to a compressed state, when the straight rack 45 moves upwards to just separate from the first straight gear 47, the elastic assembly 71 is reset from the compressed state, the elastic force enables the movable brush 72 to move back to the original position, the roller 73 rotates back to the original position, the movable brush 72 moves upwards and downwards and cleans the upper part of the front side of the display frame 2, and the automatic cleaning effect is achieved.
In the process of moving the movable brush 72 up and down, when the movable brush 72 is moved to contact with the pull plate 82, the movable brush 72 is moved to slide the pull plate 82 forward in the fourth guide sleeve 81, the second compression spring 83 is changed from the initial state to the compressed state, and simultaneously the pull plate 82 is moved to move the connecting rod 84 forward, thereby moving the elastic pull plate 65 forward, so that the switch 63 is opened, thereby spraying the water in the water tank 62 on the display frame 2, when the movable brush 72 is separated from the pull plate 82, the second compression spring 83 is reset from the compressed state, the elastic force causes the pull plate 82 and the connecting rod 84 to move back to the original position, thereby assisting the elastic pull plate 65 to move back to the original position, so that the switch 63 is closed, and the water in the water tank 62 stops flowing out.
In an initial state, the elastic pushing plate 92 is matched with the elastic clamping plate 94, when the roller 73 rotates, the roller 73 drives the ratchet gear 95 to rotate, due to the fact that the ratchet gear 95 is matched with the elastic clamping plate 94, the ratchet gear 95 rotates to enable the elastic clamping plate 94 to repeatedly slide back and forth in the sixth guide sleeve 93, meanwhile, the elastic clamping plate 94 deforms, the roller 73 rotates to enable the movable brush 72 to move downwards, the elastic assembly 71 is changed from an initial state to a compressed state, after the movable brush 72 is moved to be in contact with the elastic pushing plate 92, the movable brush 72 enables the elastic pushing plate 92 to slide downwards in the fifth guide sleeve 91, meanwhile, the elastic pushing plate 92 is changed from the initial state to the compressed state, the elastic clamping plate 94 moves forwards, meanwhile, the elastic clamping plate 94 is changed from the initial state to the compressed state, at the moment, the elastic clamping plate 94 is separated from the ratchet gear 95, when the straight rack 45 moves upwards to be separated from the first straight gear 47, the elastic assembly 71 is reset from the compressed state, the movable brush 72 returns to the original position, at the elastic pushing plate 92 and the elastic clamping plate 94 is reset from the compressed state, at the elastic clamping plate 94, at the elastic clamping plate 95 is matched with the brush, and the brush can completely moves upwards and downwards in the display frame 2 before moving process.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
