Definitions

  • This invention is related to a dual-functional medium shredding machine structure, that not only serves as conventional paper shredding machines, but also allows shredding of the commonly known optical discs containing data or expired credit cards or membership cards through a disc inport or a card inport specifically for such media.
  • This invention mainly implements a pair of shredding roller blades with sharp teeth as shredding means for shredding paper, credit cards, and membership cards.
  • This invention is provided with separate feeding inports, including an inclined inport for feeding paper, and a vertical inport for feeding discs or cards, wherein the inports are each led to the same shredding roller blades such that, regardless of the type of substance being fed by the user, the paper, cards, or the discs can all be shredded by the shredding roller blades.
  • This invention is characterized in that: an inclined inport of a longer channel and a vertical inport of a shorter channel are each provided at the machine body above the roller blades; touch switches are provided at each of the inports such that, while feeding the paper, cards, or discs, the touch switch activates the shredding roller blades to perform shredding task, and drives the switch plate so as to dispense shredded scraps of different substance into different bins.
  • Conventional paper shredding machines mostly include a roller blade set constructed of two roller blades that shred or cut paper to be fed into strips or scraps as a result of the opposed rotations of the two roller blades such that information as recorded on the paper is destroyed for confidentiality, and the strips or scraps of paper can be easily compressed to reduce processing space.
  • optical discs regardless of CD-ROM discs or CD-R discs, rather than paper have evolved to be one of the major means for storing information. Once information contained in such optical discs has lost its original value and needs to be destroyed, manually breaking the optical discs not only cannot destroy the information as stored, it also may cause personal injuries.
  • An optimum measure is to shred these discs by means of mechanical operations such as those in conventional paper shredding machines.
  • paper shredders are tools commonly used for destroying information
  • the inventor of this invention believes that the functions of the conventional paper shredders shall be expanded so as to perform shredding task on the same machine using an identical roller blade set regardless of the type of substance of the media to be shredded, given that the machine volume is not increased but the functions are enhanced.
  • this invention intends to provide a medium shredding machine that allows paper shredding and disc shredding using the same machine.
  • the inventor made researches and developments in such a valuable subject mater and accomplished the "Dual-Functional Medium Shredding Machine Structure" that provides separate feeding inports, including a paper inport for feeding paper and a disc inport for feeding discs, wherein the inports are each led to the same shredding roller blades such that, and the shredded scraps are dispensed to separate bins through an identical exit by means of an auto-revolving switch plate.
  • This invention mainly implements a pair of shredding roller blades with sharp teeth as shredding means, and is characterized by providing separate feeding inports, including a paper inport for feeding paper in an inclined orientation, and a disc inport for feeding discs in a vertical orientation, wherein the inports are each led to the same shredding roller blades such that, regardless of the type of substance being fed by the user, the paper or the discs can both be shredded by the shredding roller blades.
  • This invention is related to a dual-functional medium shredding machine structure that is substantially dimensioned to the conventional paper shredding machines serving as tools for destroying information.
  • This invention not only serves as a conventional paper-shredding machine, but also allows shredding of the commonly known optical discs or credit cards by implementing an identical set of roller blades and allows sorting and collection of different scraps.
  • a machine body 10 dimensioned to a conventional paper shredding machine is provided with a power switch 13 on a surface thereof, a pair of roller blades 18 provided therein and driven by a gearbox, and two inports on an upper lid 11 thereof, the inports including a paper inport 14 with an opening of a larger dimension and inclined, curved channel walls, and a disc inport 15 with an opening of a smaller dimension and vertical channel walls.
  • the inports 14, 15 are each led to the shredding roller blades 18 such that, regardless of the type of substance being fed by the user, the paper 25 or the disc 26 can all be shredded by the shredding roller blades 18 through the intermeshing of roller blades 18.
  • the disc inport 15, in principles, is designed to have an opening width that only allows a single piece of optical disc 26 to pass thereby preventing overloading and damaging of the roller blades 18.
  • the paper inport 14 and the disc inport 15 are, respectively, provided with a paper touch switch 16 and a disc touch switch 17 at appropriate locations of the openings or the channel walls.
  • a paper touch switch 16 As shown in Figs. 2 and 3, while feeding a piece of paper 25, the paper touches and activates the paper touch switch 16 so as to activate the shredding roller blades 18 to perform the intermeshing and shredding task.
  • the disc touches and activates the disc touch switch 17 so as to activate the shredding roller blades 18 to perform the intermeshing and shredding task.
  • the machine body 10 is provided with a scrap exit 19 at a base 12 thereof.
  • the scrap exit 19 is provided with a switch plate 20 that revolves about a shaft 23.
  • the switch plate 20 can be driven to the desired direction by means of a conventional driving mechanism (not shown) so as to change the direction that the scraps are dispensed.
  • the two touch switches 16, 17, while being provided to activate the roller blades 18, can also activate the rotation of the switch plate 20 provided at the scrap exit 19 of the base 12 so as to change the direction of the scrap exit 19 thereby dispensing shredded scraps of different substance into different bins.
  • the paper 25 touches the paper touch switch 16, which not only activates rotation of the roller blades 18, but also drives rotation of the switch plate 20 so as to dispense the scrap exit 19 towards the paper scrap bin 21.
  • the disc 26 while feeding an optical disc 26 into the disc inport 15, the disc 26 touches the disc touch switch 17, which not only activates rotation of the roller blades 18, but also drives rotation of the switch plate 20 so as to dispense the scrap exit 19 towards the dick scrap bin 22.
  • the "dual-functional medium shredding machine structure" of this invention provides two functions within an identical machine and uses an identical set of roller blades, the invention helps to reduce cost and improved space utilization. Furthermore, this invention uses two touch switches 16, 17 to activate directional change of a switch plate 20 so as to dispense shredded scraps of different substance into different bins. As such, the effects as achieved by this invention are not limited to destroying paper 25 or discs 26 within an identical machine, but also allows waste sorting and resource recycling for environmental sakes.
  • the "dual-functional medium shredding machine structure" of this invention uses two touch switches 16, 17 to activate the roller blades 18 and to drive rotational change of the switch plate 2 of the scrap exit 19 so as to dispense shredded scraps of different substance into different bins so as to facilitate waste sorting and resources recycling.
  • this invention it is known that people will mostly use this invention as means for shredding paper 25 in daily life or at professional sites; it is thus possible that scraps of discs 26 will only be a small proportion of paper.
  • the two touch switches 16, 17 can drive rotational change of the switch plate 20 so as to dispense shredded scraps of different substance into different bins, the capacity of paper pin may be insufficient for most of the time.
  • the number of touch switches in this invention may be reduced to one, and the switch plate 20 as well as the accompanying driving mechanism may also be eliminated.
  • a single touch switch is provided at an appropriate location beneath the two inports and between the roller blades, such that regardless of the type of substance being fed by the user, the paper 25 or disc 26 can both touch the touch switch so as to activate the roller blades to perform shredding task while the scraps are dispensed to an identical bin.
  • a simplified embodiment of this invention further reduces the number of components thereby reducing the manufacturing cost and enhancing competitiveness.
