The invention belongs to the field of stationery recovery machinery, and particularly relates to an automatic recovery device for penholder rubber. The automatic recovery device for the penholder rubber comprises cover plates, side walls, baffles, fixing plates, bottom plates, positioning modules, cutting modules, controllers, separating modules and a recovery groove, the cover plates are arrangedon the bottom plates through the side walls, and the positioning modules are arranged between the cover plates and the bottom plates; the positioning modules are used for fixing penholders; the baffles are positioned between the cover plates and the bottom plates, fans are arranged at the lower ends of the baffles, the fixed plates are hinged to the side walls, the separating modules are arrangedon the left surfaces of the fixing plates, and the recovery groove is formed below the bottom plates; and the controllers are used for controlling the positioning modules, the cutting modules and theseparating modules to work, motors drive the fixing plates to rotate through rotating shafts to enable clamping jaws to peel off the rubber from the penholders, and the fans blow the rubber into rubber grooves from discharging ports. The automatic recovery device for the penholder rubber is mainly used for recovering gel pens with transparent penholders which are sleeved with the rubber, and thepenholders and the rubber are separately recovered through the recovery groove, so that the utilization rate of the pen material is improved.
