A paper shredder having shredder cover and a motor coupled to shredder blades includes a shredder throat in proximity to shredder blades. The shredder throat has a moveable blade, and a fixed blade. A shredder jam grip has a projection in communication with a power switch plunger. When the shredder is in the NORMAL position, a throat gap is in its normal position and the projection positions the plunger to power to the motor. When the shredder is in the JAM CLEAR position, the throat gap is in its wide position and the projection positions the plunger to remove power from the motor.

A rotational shredder apparatus suited for properly rendering sensitive material into un-recognizable and inert waste is presented. The rotational shredder apparatus consists of a twin chamber shredder with rotary mechanism, where the rotational shredder apparatus is configured to shred sensitive material into un-recognizable and inert waste. More specifically, unprocessed waste is inserted into one of the chambers. The unprocessed waste is then passed through the shredder. The rotary mechanism then flips the twin chamber shredder such that the shredded waste from the first chamber is then directed back into the shredder, where the second chamber receives the further shredded waste. This process is repeated until the sensitive material is rendered into un-recognizable and inert waste suitable for disposal.

A paper shredder having shredder cover and a motor coupled to shredder blades includes a shredder throat coupled to an inlet in the shredder cover and in proximity to shredder blades. The shredder throat has a moveable throat blade, which widens the shredder throat. An anti-jam switch, which when activated causes the motor to advance the shredder blades to clear a jam in the widened shredder throat. The jam clearing mechanism can be automatic or manual, as by push-button or turn-knob linkages. A method for recovering from a shredder jam in a paper shredder is provided, including providing a moveable throat blade; sensing a shredder throat jammed condition; releasing the moveable throat blade; moving the moveable throat blade to a wide gap position; sensing the moveable throat blade in the wide gap position; advancing shredder blades in response to the sensing, by which the jammed condition is cleared.

A shredder mechanism is disclosed herein including first and second shredder portions positioned opposite one another and defining a slot therebetween. The first and second shredder portions each include a longitudinal support having more upper fins and a plurality of lower fins. each defining a shaft receptacle. A shaft is positioned between the upper and lower fins positioned within the shaft receptacles. A plurality of cutting blades are mounted to the shaft and extend into the slot. Each of the one or more upper fins and the plurality of lower fins extend among the plurality of cutting blades. The longitudinal support includes upper and lower support portions having the one or more upper fins secured to the upper support portion and the plurality of lower fins secured to the lower support portion.

Provided is a paper shredder comprising a housing (6) and a paper shredder head (4), wherein a transmission mechanism (5) and a motor are provided in the paper shredder head (4); the motor comprises a motor body (1), the motor body (1) having an output shaft (12) and a motor housing (11) sleeve connected on the output shaft (12); the motor housing (11) is provided with a heat dissipation device, the heat dissipation device comprising an air intake device (2) and an air output device (3); the air intake device (2) has a cold air inlet and the air output device (3) has a hot air outlet; the air intake device (2) is provided on one side of the output shaft (12) and the air output device (3) is provided on the other side of the output shaft (12); at the position where the air intake device (2) is provided on the motor housing (11) there is an air intake hole (13) opened correspondingly to communicate with an inner chamber of the motor housing (11), and at the position where the air output device (3) is provided on the motor housing (11) there is an air output hole (14) opened correspondingly to communicate with the inner chamber of the motor housing (11), such that a relatively isolated and independent heat dissipating air channel is formed internally from the cold air inlet, via the inner chamber of the motor housing (11), to the hot air outlet.

A shredder includes a shredding section that shreds paper into paper pieces, a housing section that houses the paper pieces, a bulk height sensor that detects the bulk height of the paper pieces housed in the housing section, a weight sensor that detects the weight of the paper pieces housed in the housing section, and a processor that prohibits shredding by the shredding section in response to indicating fullness of the housing section by either the bulk height detected or the weight detected.

A shredder includes a shredding unit that shreds paper into paper pieces, a tank that stores the paper pieces, a weight sensor that is provided below the tank and that measures a weight of the paper pieces inside the tank, a processor of a control unit that calculates an environmental contribution value based on the weight of the paper pieces measured by the weight sensor, and a display that displays the environmental contribution value.

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.

Provided is a portable paper shredder, relating to the technical field of portable paper shredding devices. The portable paper shredder includes a chassis and a core disposed in the chassis. The core includes a rotating drive member and a cutter assembly that are in transmission connection. The chassis is provided with a paper shredding passage. A paper shredding end of the cutter assembly is located in the paper shredding passage. The paper shredding passage penetrates the chassis. Two ends of the paper shredding passage are provided with a paper feeding end opening and a paper outfeeding end opening separately. A side of the paper shredding passage extends outwards and forms an open notch on the sidewall of the chassis. The open notch directly communicates with the paper feeding end opening. Therefore, the portable paper shredder can broaden the application scope, help achieve miniaturization and improve portability.
