The invention relates to the technical field of feeding devices, and discloses a feeding device and method for plastic tray production. The feeding device comprises a
workbench, a material receiving opening is formed in the inner wall of the
workbench, a material stirring device is arranged at the top of the
workbench, a material screening device is arranged at the bottom of the material receiving opening, and a stirring device is arranged at the bottom of the material screening device; a conveying table is fixedly mounted on the inner wall of the worktable; the material stirring device comprises a motor, a first rotating rod, a first
cam, a contact plate, a material stirring plate, a fixing column, a first moving plate, a first pressing plate, a first spring telescopic column, a supporting plate, a sliding rod, an L-shaped plate, a second spring telescopic column, a second pressing plate and a protection plate, and the motor is fixedly connected to the front portion of the workbench through a connecting plate. The plastic particles conveyed from the conveying table are stirred away, local accumulation of the plastic particles is prevented, smooth operation of the conveying table is ensured, the
downtime is shortened, and the production efficiency is improved.
