The present invention discloses an automatic paper feeding method for a paper shredder and a paper shredder, including a step of disposing paper, a step of pressing paper, a step of automatically feeding paper continuously, and a step of shredding paper. The paper sheets to be shredded entering the automatic paper feeding channel are superimposed partially; the paper disposing mechanism and the automatic paper feeding channel of the paper shredder are located at two sides of the paper rolling device respectively; the paper rolling device is located at least at the position above the lower end portion of the paper disposing area/paper sheets to be shredded. In the present invention, the paper sheets to be shredded conveyed to the automatic paper feeding channel are superimposed partially; during shredding, the shredding cutter shreds a plurality of paper sheets to be shredded at a time, with a higher feed speed and an increased shred speed. Besides, the automatic feed speed can be adjusted. The present invention has an intelligent paper feeding function, which effectively prevents the overload during the automatic paper feeding and the automatic shredding.

A paper shredder cutting assembly having an arbor, spaced-apart cutting blades on the arbor, a rigid frame set apart from and parallel to the arbor, and braces coupling the arbor to the frame. Each resilient brace is a spacer between a pair of spaced-apart cutting blades. The braces support arbor and cutting blades. The rigid frame and the braces cooperate to strengthen, and to reduce translational motion of the arbor, while allowing rotation of the arbor. Each brace has a brace body, a brace tang extending therefrom, and a brace tab extending perpendicularly from the brace tang. Each brace tab is aligned with another along an edge of the rigid frame, the brace bodies are spacers between the cutting blades, and the brace tabs impair translational motion of the brace bodies. A paper shredder with a motor, gearing, and counterposing cutting assemblies has motion-limited resilient spacers adjacent to cutting blades.

Provided is a positioning adjustment apparatus for a mobile device in scanning and photography, including a main body and a lifting unit. An object to be scanned is placed on the main body, and the mobile device placed on a carrier platform of the lifting unit can move up and down along with the lifting unit to adjust a distance between the mobile device and the object to be scanned. After scanning, a document is sent directly to a shredder. The invention also provides a wireless signal transmission to operate the mobile device for scanning or photography to meet various demands of the users.

A paper shredder includes a housing having an oblong entrance and an oblong exit for paper to be shredded, an electric motor, and a shredding mechanism driven by the electric motor and in a paper feeding path from the entrance to the exit for cutting paper entering the housing via the entrance into smaller paper pieces which exit via the exit. An exit device is attached to the exit for exit of the paper pieces. The exit device extends along the length of the exit for collecting the paper pieces, has an opening for exit of the paper pieces, and includes a moving mechanism for moving the paper pieces to the opening.

The present disclosure is generally related to an apparatus having cutter elements for destroying articles such as paper sheets and a mechanism for separating at least a sheet from a stack in a tray. A paper feed mechanism feeds paper that is separated from the stack by a stack separation mechanism to the cutter elements. The feed and separation mechanisms can be activated by rotation of the cutter elements. In one embodiment, the stack separation mechanism moves in an alternating manner between retracted and extended positions to disengage and engage and insert the stack to separate (with its edge) paper therefrom to feed to the feed mechanism for shredding. The paper stack separation mechanism can move in an non-undulating manner relative to the stack. A device for stripping stapled pages, a pivotable support plate, and pressure plate can also be used, as well as a number of sensors.

A mechanical bin-full device for a paper shredder with a bin, having a curved, perforated T-blade sensor on a cylindrical body partially covered with a metal sheet. The T-blade is pendent into the bin. Metal contacts are placed on the paper shredder near the metal sheet, forming a switch, which is coupled to a motor control circuit for the shredder motor. The T-blade is pushed by paper shreddant and rotates the cylinder body as paper shreddant fills the bin. When the bin becomes full, the T-blade is positioned so that the metal contacts touch the metal sheet, closing the control circuit switch, and causing the motor to cease operating. The control circuit can include a microcontroller coupled to the motor, or a transistor-based driver coupled to a motor relay.

A paper shredder motor cooling assembly having a paper shredder motor coupled to a fan shaft, an enclosure surrounding the paper shredder motor and having selected input and selected output vents to control airflow to the paper shredder motor, a fan coupled to the fan shaft, communicating with the selected input vents or the selected output vents; when the paper shredder motor is operating, the rotor shaft turns the fan to generate a differential air pressure between the selected input vents and the selected output vents, removing heat from the motor. A duty cycle of greater than 15 minutes is obtained. The fan can be coupled to the motor by speed increasing gearing, attached to the cutter blade assembly, such that the fan turns faster than the motor. The fan also can be attached to the motor shaft. An input fan and an output fan can be used.

Provided is a sheet processing device able to suppress consumption of sheets. The sheet processing device has a supply device that supplies sheets; an image acquisition device that acquires an image of a sheet supplied from the supply device; a first decision device that determines whether or not the sheet can be reused based on the image of the sheet acquired by the image acquisition device; and an inverter configured to discharge the sheet without reversing the first side and second side of the sheet when the first decision device determines that the first side of the sheet can be reused, and reverses the first side and second side of the sheet and then discharges the sheet when the first decision device determines that the second side of the sheet can be reused.
