Dual-functional medium shredding machine structure

Abstract

This invention is related to a dual-functional medium shredding machine structure, specifically designed for shredding or destroying paper printed with data to be destroyed, optical discs containing data to be destroyed, or expired credit cards. 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, and the shredded scraps are dispensed to separate collectors through an identical exit by means of an auto-revolving switch plate; and a touch switch at each of the inports such that, while feeding the paper or the 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 collectors.

1. A dual-functional medium shredding machine structure, that allows shredding of paper, optical discs, and credit cards, characterized in comprising:
 a machine body being provided with a power switch on a surface thereof and roller blades therein, the roller blades being driven by a gearbox;  
 two inports on an upper limit thereof, the inports including a paper inport with an opening of a larger dimension and inclined, curved channel walls, and a disc inport with an opening of a smaller dimension and vertical channel walls, the inports being each led to the shredding roller blades such that, regardless of the type of substance being fed by a user, the paper or the disc can all be shredded by the shredding roller blades through the intermeshing of roller blades;  
 a paper touch switch being provided at an appropriate location between the paper inport and the roller blades; and  
 a disc touch switch being provided at an appropriate location between the paper inport and the roller blades;  
 whereby the roller blades are activated by the touch switches when paper, discs, or credit cards are fed and touch the touch switches so as to activate the roller blades to perform intermeshing and shredding task.  
 
     
     
       2. The dual-functional medium shredding machine structure of  claim 1 , wherein the machine body is provided with a scrap exit at a base thereof, the scrap exit being provided with a switch plate that is switchable to a desired direction by means of a driving mechanism, such that while the paper touch switch or the disc touch switch is touched by paper, discs, or credit cards, the touch switch also activates rotation of the switch plate so as to change the direction of the scrap exit thereby dispensing shredded scraps of different substance into different bins. 
     
     
       3. The dual-functional medium shredding machine structure of  claim 1 , wherein the disc inport is dimensioned to have an opening width that only allows a single piece of optical disc or credit card to pass thereby preventing overloading and damaging of the roller blade. 
     
     
       4. The dual-functional medium shredding machine structure of  claim 1 , wherein the paper inport and the disc or card inport are both led to the roller blades, a single touch switch is provided between the roller blades such that regardless of the type of substances being fed by a user, the paper, disc, or credit cards can all touch the touch switch so as to activate the roller blades to perform shredding task while the scraps are all dispensed to an identical bin. 
     
     
       5. A dual- functional medium shredding machine structure, that allows shredding of paper and optical discs or credit cards, characterized in comprising:      a machine body being provided with a power switch on a surface thereof and intermeshing shredding blades therein;        two inports on an upper lid thereof, the inports including a paper inport with an opening of a larger dimension and inclined, curved channel walls, and a disc or card inport with an opening of a smaller dimension and vertical channel walls, the inports being each led to the shredding blades such that, regardless of whether the type of substance being fed by a user is paper, an optical disc, or a card, the paper, card, or disc can all be shredded by the shredding blades through the intermeshing of the blades.      
     
     
       6. The dual- functional medium shredding machine structure of    claim 5   , further comprising a first blade - activation switch situated between the paper inport and the shredding blades and a second blade - activation switch situated between the disc or card inport and the shredding blades, wherein the machine body is provided with a scrap exit at a base thereof, the scrap exit being provided with a switch plate that is switchable to a desired direction by means of a driving mechanism, such that while a respective one of said first or second blade - activation switches is caused to activate said shredding blades by the presence of paper, a disc, or a card in one of the inports, the respective first or second blade - activation switch also activates rotation or the switch plate so as to change the direction of the scrap exit thereby dispensing shredded scraps of different substance into different bins.    
     
     
       7. The dual- functional medium shredding machine structure of    claim 5   , wherein the disc or card inport is dimensioned to have an opening width that only allows a single piece of optical disc or credit card to pass thereby preventing overloading and damaging of the shredding blades.    
     
     
       8. The dual- functional medium shredding machine structure of    claim 5   , wherein the paper inport and the disc or card inport are both led to the shredding blades, and a single switch is provided between the shredding blades such that regardless of the type of substance being fed by a user, the paper, disc, or credit cards can all cause the switch to activate the shredding blades to perform a shredding task while the scraps are all dispensed to an identical bin.    
     
     
       9. The dual- functional medium shredding machine structure of    claim 5   , wherein:      a first blade - activation switch is provided at an appropriate location between the paper inport and the shredding blades; and        a second blade - activation switch is provided at an appropriate location between the disc inport and the shredding blades;        whereby the shredding blades are activated by the first or second blade - activation switch to perform an intermeshing and shredding task when paper, discs, or credit cards are fed into either of the paper and disc or card inports.      
     
     
       10. A dual- functional medium shredding machine structure, that allows shredding of paper and optical discs or credit cards, characterized in comprising:      a machine body being provided with intermeshing shredding blades therein;        two inports on an upper lid thereof, the inports including a paper inport with an opening of a larger dimension and inclined, curved channel walls, and a disc or card inport with an opening of a smaller dimension and vertical channel walls, the inports being each led to the shredding blades such that, regardless of whether the type of substance being fed by a user is paper, an optical disc, or a card, the paper, card, or disc can all be shredded by the shredding blades through the intermeshing of the blades.      
     
     
       11. A dual- functional medium shredding machine structure, that allows shredding of paper and optical discs or credit cards, characterized in comprising:      a machine body being provided with intermeshing shredding blades therein;        two inports on an upper lid thereof, the inports including a paper inport with an opening of a larger dimension and inclined, curved channel walls, and a disc or card inport with an opening of a smaller dimension and vertical channel walls, the inports being each led to the shredding blades such that, regardless of whether the type of substance being fed by a user is paper, an optical disc, or a card, the paper, card, or disc can all be shredded by the shredding blades through the intermeshing of the blades; and        a switch arranged to activate the shredding blades to perform an intermeshing and shredding task when paper, an optical disc, or a card is being fed by the user.
