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.

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.

A portable shredder unit that includes a lightweight housing with a large interior cavity divided into a battery storage cavity and a collection cavity. Mounted on lid of the housing is a high capacity paper shredder component. Located inside the battery storage cavity is at least one 12 VDC rechargeable battery. The battery is connected to an inverter configured to convert the 12 VDC current into 110 VAC current required by the shredder component. Mounted on one end of the housing is a pair of wheels. Mounted on the opposite end of the housing is a pivoting or retractable handle that enables the unit to be pulled across a flat surface. The unit includes a control panel with a mode switch that controls the electricity source to the shredder component. An electrical cable is mounted on a wire retracting mechanism located inside the housing or lid. An optional battery charger is, also provided.

An air extraction and heat dissipation structure for paper shredders, wherein the outer wall of the main handle is inlaid with switch button, the right side of the handle is connected with the power cord hook, the end of the handle is fixed with the connecting rod, and the bottom end of the rod is connected with a main body. The motor is arranged on the inner side of the heat dissipation port, the end of the motor is connected with the dust suction device, at the lower left end of which the dust storage chamber is arranged, and a dust suction channel is fixed at the right end of the chamber. The bottom end of the channel is connected with rollers, the left side of the rollers is provided with a suction cup, and the surface of the suction cup is provided with a dust suction port for paper shredders.

An article destruction device includes an electric motor driving at least one moving component. An indication panel includes at least three visual indicators situated in sequence. Each visual indicator is associated with a stage of an approaching overload (motor cool down) condition. A first visual indicator lights when the motor or corresponding sensor temperature is below a first threshold, i.e., when the device is first powered on. A second indicator lights when the temperature exceeds the first threshold and is below at least a second threshold, i.e., the temperature is approaching a fault condition. A last visual indicator lights when the temperature exceeds the first and the at least second thresholds, i.e., the fault condition is met. A thermistor on the motor energizes (self-heats) with the motor. A thermostatic switch controls current flow through windings of the motor depending on measured temperatures meeting operating and equilibrium temperature thresholds.

A paper shredder controller, with an all-analog controller including a power supply circuit, coupled to a door open switch circuit, an automatic forward control circuit, an automatic reverse control circuit, and a wastebin full circuit. The paper shredder controller includes an overload circuit, a forward-reverse control and relays circuit, a forward-reverse model delay setting circuit, and an overheating protection circuit. Further includes a POWER indicator light; a DOOR OPEN light; an AUTOMATIC FORWARD light; an OVERHEATING light, and a WASTEBIN FULL light.

A shredder includes a strip-cut shredding portion including paired disc-shaped, multi-plate rotary cutters meshing with each other to shred paper in a strip-cut direction, and a cross-cut shredding portion including a fixed cutter and a spiral rotary cutter for further shredding strip-cut waste pieces discharged from the strip-cut shredding portion in a cross-cut direction, the shredder including a unit for detecting that the spiral rotary cutter of the cross-cut shredding portion is not rotating. Shredding by the strip-cut shredding portion is stopped when the sensor unit detects that the spiral rotary cutter is not rotating.

An inclined automatic paper shredder with structure for facilitating multi-stage staple removal from a stack of to-be-shredded paper. The shredder includes a paper pressing part arranged on a lower surface of a cover plate to press against the stack of paper disposed on a paper holding part. A staple removing plate is pivotally connected to an upper surface of the cover plate and can be opened in a first rotational direction. The staple removing plate rests in its the closed state on the upper surface of the cover plate and in its open state. The staple removing plate may rotate to abut against the stacked to-be-shredded paper on the paper holding plate and removes the staples on the stacked to-be-shredded paper.

A shredding machine includes an outer housing including a main portion and a door. The outer housing defines an interior space. A shredding engine positioned above the interior space includes a shredding motor and a plurality of interleaved cutters. A material passage is configured to receive material to be shredded and direct the material to be shredded to the plurality of interleaved cutters. A collection bin is constructed of transparent material and removably received inside the interior space, the collection bin being open at a top end and defining a central vertical axis. An interior lighting element is operable to emit light in the visible spectrum into the collection bin. During operation of the shredding engine, the collection bin is configured to rotate within the outer housing about the central vertical axis and the interior lighting element is energized to illuminate shredded material as it falls into the collection bin.
