An automatic shredder comprises an upper shredder cover, a lower shredder cover, a first paper box, a second paper box, a shredder cover plate, a paper pressing plate, a paper pressing roller set, a paper pick-up roller set, a paper inlet, a cutter shaft set, a drive motor, a shell and a waste paper barrel. The automatic shredder adopts a bent paper box to change the length of to-be-shredded paper by means of the flexibility and bendability of paper and the features of paper pick-up rollers on one side, is extremely simple and economical, and changes the flat paper placement structure of existing automatic shredders.

An illustrated view of an exemplary cardboard shredder for compressing and shredding cardboard is presented. The cardboard shredder provides a shredder for cardboard to facilitate recycling while reducing storage space needed before cardboard enters a recycling stream and cutting out the middleman, thus the recycler receives uncontaminated cardboard since it is not mixed in with other materials. The manufacturer receives clean shredded cardboard for reuse, reducing headcount for the plant by reducing and eliminating their shredders being jammed with plastic. The cardboard shredder further saves space in residential and commercial spaces and increases intervals between container emptying, thus making recycling of cardboard easier while saving time and money. The carboard shredder is designed to fit over standing large garbage cans to eliminate double handling of the cardboard prior to recycling. The cardboard shredder further accommodates larger sizes of product to be shredded than a conventional paper shredder encouraging recycling of cardboard.

Thus, an improvement in efficiency and reduction in costs of material and water.

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.

A paper shredder is configured like a conventional paper shredder except that the shredding mechanism is located in a removable cartridge. This allows a single paper shredder housing to be rapidly converted from one shredding pattern to another by simply changing the shredding cartridge. Furthermore, shredding cartridges can be readily replaced whenever the shredding mechanism jams or fails in some other manner. This simplifies repair and servicing of the paper shredder.

A portable shredder unit includes a lightweight housing with an interior cavity divided into a battery storage cavity and a collection cavity, said housing includes a top opening, two opposite ends, two opposite side walls, and a floor; a removable lid attached to said top opening on said housing; a high capacity electric shredder component configured to shred paper, said shredder component includes at least one feeding slot opening, an electric shredding mechanism, and electric motor and an exit discharge opening said shredder component being oriented on said lid so that said feeding slot opening is exposed when the lid is placed over the top opening of said housing and said exit discharge opening is oriented above and over said collection cavity in said housing so that shredded material exiting the exit discharge opening is deposited into said collection cavity; at least one pair of wheels attached to said housing near one said end; a handle attached to said housing; a GFCI receptacle having a ground wire; a 110 VAC main cable with a male electrical plug attached to one end configured to manually plug into an external 110 VAC female plug, and an opposite end being connected to said GFCI receptacle; at least one 12 VDC rechargeable battery located inside said battery storage cavity; an inverter configured to convert 12 VDC into 110 VAC, said inverter connected to said rechargeable battery to convert 12 VDC current into 110 VAC, said inverter; a control panel or set of switches electrically connected to said shredder, to said inverter and to said GFCI receptacle, said control panel or set of switches are configured to allow an operator to select the source of electricity either from said GFCI receptacle when said main cable is connected to an external 110 VAC female plug or from said inverter when connected to said rechargeable battery; and a ground roller ball attached to the floor of the housing and configured to contact a surface under the housing when the portable shredding unit is placed onto the surface said ground roller ball electrically connected to the ground wire of said GFCI receptacle.

A lottery ticket destroying device includes a housing, roller cutters mounted in the housing, a transmission gear set mounted on one side of the housing, a motor mounted on one side of the housing for rotating the transmission gear set to drive the roller cutters to cut lottery tickets into pieces. Each roller cutter has a plurality of helical shear grooves recessed into the roller cutter surface thereof. Each helical shear groove has a groove bottom surface, a vertical shear surface located on one side of the groove bottom surface and connected to the roller cutter surface and a chip-discharge sloping surface located on an opposite side of the groove bottom surface and connected to the roller cutter surface. Moreover, one end of the shaft of one of the roller cutters is combined with an elastic member to prevent the two roller cutters from being stuck.

A stand-alone self-service document shredding machine that receives the documents, shreds them, and securely stores the shredded documents in a receiving bin for later removal. There is a feeder mechanism that feeds the documents yet protects the user from injury when the shredder machine is operating. The shredded documents are disbursed across the receiving bin. The user interfaces with the shredding machine by means of a touch screen and can pay with a credit or debit card or an account set up online.

A small-form-factor high-security destruction machine for optical media has a weight empty of about 16.3 lbs and holds about 5 lbs of residue.

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.
