During operation, the chain moves on guide rail 3, gyro wheel 64 under the chain moves on elastic rubber strip 65, and gyro wheel 64 will bear the weight of conveying chain 6 and rolling slats door 2, make gyro wheel 64 compress the cavity 66 of elastic rubber strip 65, compressed cavity 66 blows outward through gas pocket two, make the dust in the guide rail 3 blown away, be favorable to the cleanness of guide rail 3, avoid guide rail 3 to pile up and make conveying chain 6 be difficult to slide in guide rail 3 because of the dust, be favorable to keeping the performance of filing cabinet.
The specific use flow is as follows:
when the filing cabinet is opened, the control button 7 is pressed, the motor 5 rotates forwards under the control of the controller, the motor 5 drives the transmission chain 6 through the driving gear 52 to drive the rolling door 2 to move on the guide rail 3, so that the rolling door 2 moves towards the rear section guide rail 33 along the guide rail 3, the filing cabinet is opened, and in the moving process of the transmission chain 6, the driving shaft 51 rotates and winds the pull rope 54, so that the pull rope 54 pulls the transmission chain 6, the rear end of the transmission chain 6 is pulled to move along the guide rail 3, the transmission chain 6 can move on the guide rail 3 more smoothly, the possibility that the transmission chain 6 is clamped is reduced, and the running power of the transmission chain 6 on the guide rail 3 is sufficient; meanwhile, the elastic air bag I55 on the pull rope 54 is pressed to exhaust air when passing through the convex rib 34, so that dust in the guide rail 3 and at the end part of the rolling door 2 can be blown out, on one hand, the cleaning of the guide rail 3 and the rolling door 2 is facilitated, the blocking of the guide rail 3 due to the dust accumulated after long-time use is avoided, on the other hand, the air fluidity of the rolling door 2 and the guide rail 3 is improved, the air exchange inside and outside the file cabinet is promoted, the mildew air accumulated in the file cabinet is avoided, and the air in the file cabinet is facilitated to be fresh;
when mixed particles of activated carbon and a drying agent are placed in the elastic air bag I55, after the gas enters the elastic air bag I55, the gas with peculiar smell is adsorbed by the activated carbon to become fresh, the gas with water vapor enters the elastic air bag I55 and is dried, then the gas inside and outside the elastic air bag I55 is compressed, and therefore the exchange of the gas inside and outside the elastic air bag I55 is achieved, on one hand, the filtering of the gas inside the file cabinet is achieved, the peculiar smell of the gas inside the file cabinet is removed, on the other hand, the gas inside the file cabinet is dried, and the moisture and the mildew of the files inside the file cabinet are avoided;
when the file cabinet is closed, the control button 7 is pressed, under the control of the controller, the motor 5 rotates reversely, the motor 5 drives the transmission chain 6 through the driving gear 52 to drive the rolling door 2 to move on the guide rail 3, so that the rolling door 2 moves towards the front section guide rail 31 along the guide rail 3, the file cabinet is gradually closed, the motor 5 drives the driving shaft 51 to rotate, so that the cam 56 intermittently extrudes the second elastic air bag 57, the controller controls the electromagnetic valve on the exhaust pipe to close, the air in the second elastic air bag 57 enters the elastic air pipe 35 through the air outlet pipe, along with the increase of the air in the elastic air pipe 35, the air in the elastic air pipe 35 applies pressure to the light and light elastic ball 36, so that the light and light elastic ball 36 pushes the first chain link 67 of the transmission chain 6 to move towards the end part of the front section guide rail 31, so that the transmission chain 6 has traction force when moving towards the front end guide rail 3, the possibility of the conveyor chain 6 getting stuck is reduced so that the conveyor chain 6 runs sufficiently power on the guide rail 3.
When the light elastic ball 36 pushes the first chain link 67 to move, because the magnets I are arranged in the light elastic ball 36 and the magnets II are arranged on the surface of the first chain link 67, when the light elastic ball 36 pushes the first chain link 67, the light elastic ball 36 is prevented from being worn by the fact that the first chain link 67 is squeezed by the outer wall of the elastic air pipe 35 through repulsive force between the magnets I and the magnets II, and the service life of the file cabinet is prolonged; when the chain slides on the guide rail 3, the abrasion of the conveying chain 6 and the guide rail 3 can be reduced through the action of the first graphite strip 61 and the second graphite strip 62, meanwhile, the conveying chain 6 can slide on the guide rail 3 more easily, and on the other hand, the contact end faces of the first graphite strip 61 and the second graphite strip 62 are adaptive inclined planes, so that the conveying chain 6 runs on the guide rail 3 more stably, the probability that the conveying chain 6 swings to collide with the guide rail 3 is reduced, and the probability that the conveying chain 6 is damaged is reduced; meanwhile, the chain moves on the guide rail 3, the roller 64 under the chain moves on the elastic rubber strip 65, the roller 64 bears the weight of the conveying chain 6 and the rolling door 2, the roller 64 compresses the cavity 66 of the elastic rubber strip 65, the compressed cavity 66 blows outwards through the air hole II, dust in the guide rail 3 is blown away, cleaning of the guide rail 3 is facilitated, the problem that the conveying chain 6 is difficult to slide in the guide rail 3 due to dust accumulation of the guide rail 3 is avoided, and usability of the file cabinet is maintained.
Industrial applicability
According to the invention, the driving shaft rotates to wind the pull rope, so that the pull rope pulls the transmission chain, the rear end of the transmission chain is subjected to traction force to move along the guide rail, the transmission chain can run on the guide rail more smoothly, and the possibility of the transmission chain being blocked is reduced; meanwhile, the first elastic air bag on the pull rope is pressed to exhaust air when passing through the convex rib, so that dust in the guide rail and at the end part of the rolling door can be blown out, the cleaning of the guide rail and the rolling door is facilitated, the guide rail is prevented from being blocked due to the accumulated dust after being used for a long time, the air exchange inside and outside the file cabinet is promoted, the accumulation of mildew air in the file cabinet is avoided, and the air in the file cabinet is facilitated to be fresh; the motorized roller shutter file cabinet is therefore useful in the field of file cabinet technology.
