An energy-saving auto feed shredder which includes an operable cover as configured in a conventional auto feed shredder, with a pressing device configured on the cover. Once the cover is open, other components are exposed, such as a feeder base or compartment to place the stack of paper, a feeder slot in the middle of the feeder base or compartment, feeding mechanisms on both sides of the feeder slot, and a shredder mechanism below the feeder slot; when the cover is closed, the pressing device applies a pressure on the stack of paper inside the feeder base, and the feeding mechanisms in relative motion on both sides of the feeder slot captures and pulls the sheet at the bottom of the stack of paper under pressure, and force it to fold toward the feeder slot, and be delivered to the shredder mechanism. Repeatedly, new sheet of paper is captured, pulled, folded and delivered by the feeding mechanism, until the whole stack of paper is shredded. Wherein, the feeder slot is in nearly parallel orientation with the folding line of the shorter side of the stack of paper placed inside the feeder base, so that the shorter side of the stack of paper can be captured, pulled, folded and delivered to the shredder mechanism by the feeding mechanism.

An ecologically sound and environmentally friendly mailbox apparatus comprising a traditional mailbox; a shredding device affixed to the underside of the mailbox; a hollow tube, having a first end and a second end; a hollow receptacle for collecting shredded material, and that is connected to the shredding device by way of the hollow tube, where the first end of the hollow tube is connected to the shredding device and the second end of the hollow tube is directed downward and is connected to the receptacle; and a vertically positioned pole located adjacent to the mailbox and the receptacle, whereby the mailbox and the receptacle are individually connected to the pole by a fastening means that holds the entire apparatus together. This apparatus allows an end user to shred junk mail before leaving his mailbox and prevent clutter in his home.

An automatic paper shredder includes a shredder cover, a paper holding box, a shell, a paper holding plate, a paper holding plate inlet, a paper shredding component, a drive motor, a paper pressing plate, a paper pick-up component, and a waste paper bin. The paper pressing effect is improved through a spliced paper pressing plate, and the paper pick-up effect is improved through a damping plate, a soft rubber piece, and a convex rib, and thus, efficiency is improved. The automatic paper shredder has the characteristics of being highly automated, convenient to use, safe, reliable, structurally simple and cost-effective.

The present invention involves a collapsible and disposable container that is inserted into a paper shredder to catch the shredded paper fragments. The disposable container has a relatively narrow slot-shaped opening having a length less than the longest dimension of the top of the container. A pair of counter-rotating rollers is supplied to compact the paper fragments and feed them through the slot and into the waste container. Various sensor systems, some constructed from conductive ink are used with and within the disposable container.

Auto-feeding paper shredders use auto-feed mechanisms to remove sheets of paper from a large stack and shred them without human assistance or intervention. Once the document owner inserts the stack of confidential documents and leaves the scene, others are free to access the stack and read or remove confidential documents. This problem by providing a locked shredding compartment to hold the stack while shredding is taking place. An electronically operated lock that can be locked and unlocked by entering a PIN (personal identification number) through a key pad or a series of buttons or switches. Fingerprints or other biometric factors can also be used to control the lock.

A shredding apparatus for value documents, includes two mutually counter-rotatable roller-shaped cutting devices which are disposed opposite each other with reference to a transport path of the value documents to be shredded, in order to cut up the value documents transported along the transport path with the aid of the cutting edges into a multiplicity of value document shreds. A stripper is allocated to each of the cutting devices, which stripper has several stripper elements arranged parallel to each other, which stripper elements engage between the cutting edges of the respective cutting device in order to remove the value document shreds from the cutting edges. The shape of the stripper elements is chosen such that the stripper elements on the front side of the respective cutting device, the front side facing the transport path of the value documents, engage between the cutting edges of the respective cutting device.

A crushing apparatus includes a first rotary shaft member, a second rotary shaft member, a plurality of first rotary cutters, a plurality of second rotary cutters, a plurality of first spacers, and a plurality of second spacers, the first rotary cutters and the first spacers being alternately disposed in a first axis direction, the second rotary cutters and the second spacers being alternately disposed in the first axis direction, the first rotary cutters and the second rotary cutters each forming a tearing blade that protrudes in a direction perpendicular to the first axis direction, a portion of each of the first rotary cutters and a portion of each of the second rotary cutters overlapping when viewed from the first axis direction, and a gap being provided between the first rotary cutter and the second rotary cutter in the first axis direction.

An apparatus for paper shredding and compacting which includes a shredded paper storage portion, a movable disposed within the shredded paper storage portion, and a movable push rod.

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.

The present invention relates to a roll film shredding device, and more specifically to a roll film shredding device which rapidly and effectively shreds a long object rolled up into a roll shape, and in particular twists and crumples an object and then performs a shredding operation, thereby effectively shredding an object even though the object is thin, flexible and viscid. The roll film shredding device according to the present invention includes a support frame; an object-to-be-shredded introducing member coupled to the support frame; an object-to-be-shredded twisting unit rotatably installed to the object-to-be-shredded introducing member and performing a twisting operation for an object to be shredded; a rotary driver driving the object-to-be-shredded twisting unit to rotate and perform the twisting operation; and a cutter cutting the object twisted by the object-to-be-shredded twisting unit.
