Paper recovery device

The invention discloses a paper recovery device. The paper recovery device comprises a controller and an executing mechanism; the executing mechanism comprises an upper guide plate and a lower guide plate, a friction wheel mechanism is arranged above the upper guide plate and comprises an upper pressing wheel support and a lower pressing wheel support, the front end of the upper pressing wheel support is in rotatable connection with the front end of the lower pressing wheel support, and a spring is arranged between the upper pressing wheel support and the lower pressing wheel support; a pressing wheel is arranged at the bottom of the lower pressing wheel support, is in rotatable connection with the lower pressing wheel support and extends out of the upper guide plate downwards, a driving wheel and a driving mechanism for driving the driving wheel to move are arranged below the lower guide plate, the driving wheel extends out of the lower guide plate upwards and extrudes the pressing wheel to enable the spring to be in the compression state, a first sensor and a second sensor for detecting paper are arranged on the front side and the back side of the friction wheel mechanism respectively, and the driving mechanism, the first sensor and the second sensor are electrically connected with the controller. By means of the paper recovery device, the paper can be safely and stably recovered; the paper recovery device is simple in structure, safe and reliable.
