This invention pertains to the category of the paper shredder technology, more particularly, the invention relates to a paper shredder without wastebasket.
A conventional paper shredder includes a cutting head and a wastebasket, in which the cutting head is configured above the wastebasket. On one hand, as the wastebasket acts as one of the essential components of shredders to collect the paper scraps falling off the paper exit that is disposed on the cutting head, it occupies a relatively large space of the paper shredder. Furthermore, in the process of shredding, it is highly inconvenient for users to clear up the wastebasket on a regular basis. On the other hand, the cutter shaft set at the bottom of the cutting head is uncovered at the paper exit, there is a potential safety hazards that users may get hurt while clearing up the wastebasket.
In view of abovementioned problems, it is one object of the invention to overcome the drawbacks of the prior art by providing a safe and reliable paper shredder without wastebasket.
To achieve aforesaid object, the adopted technical solution is described below:
A paper shredder without wastebasket, in accordance with this invention, comprises a cutting head, having a paper exit disposed at the bottom thereof. The bottom of the cutting head is connected with a scrap discharge unit, which includes a housing, a rotating screw and a driving mechanism. At the upper end of the housing is disposed with a scrap collecting groove, on one side of the housing is disposed with a scrap outlet, a rotating screw for discharging paper scraps out of the housing is disposed within the housing chamber and one end of the rotating screw is connected with the driving mechanism.
Specifically, the driving mechanism is one-way transmission gears, which are fixed on a rotating shaft that is disposed at one end of the rotating screw.
More specifically, the one-way transmission gears are connected with a drive motor or drive gears that are disposed within the cutting head to drive a cutter shaft set.
Advantages of this invention are described as follows:
In accordance with the present invention, the bottom of the cutting head is connected with a scrap discharge unit, which includes a housing, a rotating screw and a driving mechanism, wherein at the upper end of the housing is disposed with a scrap collecting groove, on one side of the housing is disposed with a scrap outlet, a rotating screw for discharging scraps out of the housing is disposed within the housing chamber and one end of the rotating screw is connected with the driving mechanism. When the paper shredder provided in the invention is in operation, the driving mechanism drives the rotating screw to rotate so as to deliver paper scraps to the scrap outlet to complete discharging. The scrap discharge unit provided herein enables the paper shredder to be used without wastebasket, and meanwhile the paper exit is covered by the scrap discharge unit, therefore the safety is largely improved.
As shown in
In accordance with a preferred embodiment, the driving mechanism is one-way transmission gears 6, which are fixed on a rotating shaft that is disposed at one end of the rotating screw 3.
Specifically, the one-way transmission gears 6 are connected with a drive motor, which drives the one-way transmission gear 6 to rotate to further drive the rotating screw 3 to rotate so as to discharge paper scraps within the housing 2 out of the scrap outlet 5.
In accordance with the preferred embodiment, the one-way transmission gears 6 are connected to drive gears that are disposed within the cutting head 1 and which are intended to drive the cutter shaft set, specifically, said drive gears drive the one-way transmission gears 6 to rotate to further drive the rotating screw 3 to rotate so as to discharge paper scraps within the housing 2 out of the scrap outlet 5.
When the paper shredder provided in the invention is in operation, papers are firstly shredded into scraps by the cutter shaft set within the cutting head and then the paper scraps fall off from the paper exit. The paper scraps fall on the rotating screw 3 within the housing 2 via the scrap collecting groove. The one-way transmission gears 6 drive the rotating screw 3 to rotate so that paper scraps on the rotating screw 3 can be delivered to the scrap outlet 5 to complete discharging. The scrap discharge unit provided herein enables the paper shredder to be used without wastebasket, and meanwhile the paper exit is covered by the scrap discharge unit, therefore the safety is largely improved.
The foregoing description is only a preferred embodiment of the invention. People who are skilled in the related art can easily produce the alternative embodiments or improvements based on the above detailed description. The present invention is not limited to the above detailed description.
