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. However, 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.
In the highly economized society as of today, plastic money, such as credit cards, debit cards, ATM cards, or even membership cards issued by enterprises for promotional purposes, and registration cards issued by medical institutions, have made “cards” become an article that can certainly be found in everyone's pocket. When these cards have expired or been replaced with new cards, the most commonly adopted measure is to cut the cards in halves for disposal. However, danger still exists in such a disposing measure because most cards carry the user's signature and the registration cards may also carry personal, medical history, or personal information. It is possible that other individuals with malicious intention may still have access to these halved cards.
Though 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. In other words, this invention intends to provide a medium shredding machine that allows paper shredding and disc shredding using the same machine.
In view of the above, the inventor made researches and developments in such a valuable subject matter 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.
It is thus a primary object of this invention to provide a “dual-functional medium shredding machine structure” specifically designed for shredding or destroying paper printed with data to be destroyed, and optical discs containing data to be destroyed, and 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.
It is another object of this invention to provide 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 bins, whereby the paper and discs can all be destroyed and shredded while the different types of shredded scraps can be dispersed into different bins through the auto-switching function of the switch plate in order to sort the waste and to recycle the resources for environmental sakes.
In order to clearly delineate the objects, characteristics and advantages of the present invention, a few preferred embodiments are specifically explained in detail in accompany with the drawings as follows.

13 power switch
14 paper inport
15 disc inport
16 paper touch switch

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.
As shown in
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. As shown in
In this invention, 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.
As shown in
As shown in
Because 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. However, 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. Though 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. Furthermore, in consideration of reduction of manufacturing cost and in response to the market demands, 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. In other words, 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. As such, a simplified embodiment of this invention further reduces the number of components thereby reducing the manufacturing cost and enhancing competitiveness.
From the invention thus described, it will be obvious that this invention as described above is provided for explanation and that the invention may be varied in many ways, where such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended for inclusion within the scope of the following claims.
