Abstract

The utility model relates to an electric paper shredder, comprising an engine block which consists of an external shell and a double-hob paper-shredding device on whose posterosuperior side the paper feeding device is positioned, and a paper box which is positioned slantwise above the paper feeding device. The paper feeding device consists of a reel spindle with rubber wheels positioned between two side panels. A paper platform is positioned below the reel spindle, and a back panel is positioned slantwise behind the reel spindle on one end of which reduction gears and a paper feeding motor are positioned. A waste-paper basket and a paper-sorting device can be also installed. With high secrecy function, the electric paper shredder can shred large piles of documents from the paper box successively and automatically. When the lid of the paper box is put on, the switch of the safety lock is locked automatically until all the documents are shredded, and several seconds after the electric paper shredder completes the task, the lid of the paper box opens automatically so that the next worker can handle the task of shredding paper. The shredder used easily and conveniently, the efficiency of the electric paper shredder with high secrecy function is much higher than that of the traditional shredder.

Description

Electric shredder

Technical field

The utility model belongs to the shredder technical field, specifically is a kind of electric shredder, and it can tear up the big heap file in the paper box of packing into successively automatically.

Background technology

All shredders on the market only can tear up limited paper now, at every turn can only broken one or several files or tens files, adopt manual paper feed more, and to operate loaded down with trivial detailsly, efficient is low.If being opened file, hundreds of needs to handle just suitable trouble and time-consuming.

Summary of the invention

For overcoming existing shredder above shortcomings, the utility model provides a kind of electric shredder, and it can tear up the big heap file in the paper box of packing into successively automatically.

The utility model electric shredder is to realize like this, it comprises body and paper box, body contains the thread hob paper shredder of shell and motor driving, and the back upside of described thread hob paper shredder is provided with paper-advance unit, and described paper box tilts to be installed on the top of paper-advance unit; Described paper-advance unit comprises the spool of the band rubber wheel that is installed between the biside plate, paper platform is arranged below the spool, and the back of spool is obliquely installed backboard, and spool one end is installed train of reduction gears and paper feed motor.This electric shredder also is provided with litter decoration, and described body and paper box are installed on the litter decoration.

Above-mentioned paper-advance unit also comprises and selects the paper device, select the paper utensil to select the paper push rod, select the paper push rod to be installed in the notch on the side plate, select paper push rod lower end and described backboard to fix, select paper push rod upper end to pass from the upper port of described notch, before and after stir and select the paper push rod can change the angle of inclination of backboard, to select what of paper feed number.

This electric shredder has the thread hob paper shredder of paper-advance unit and motor driving, and it can tear up the big heap file in the paper box of packing into successively automatically.But also possesses highly confidential function, when the cover of paper box once cover the safety lock switch can auto lock till file all tears up, the paper box cover will be opened automatically after shredder is finished the work the several seconds, allow the next worker can handle shredded paper work, convenient easy-to-use, safe and secret, efficient is far above traditional shredder.

In addition, also added and selected the paper function, can select each broken a piece of paper or each broken plurality of sheets of paper, this function can be saved the working time effectively, raises the efficiency.

The specific embodiment

Below in conjunction with the embodiment accompanying drawing the utility model is further described.

With reference to Fig. 1, embodiment 1 electric shredder comprises body 4 and paper box 1, body 4 contains the thread hob paper shredder and the paper-advance unit of shell, motor driving, this paper-advance unit is arranged at the back upside of thread hob paper shredder, described paper box 1 tilts to be installed on the top of paper-advance unit, and the paper device 3 that selects of paper-advance unit is positioned at a side of paper box 1.

Fig. 2 a, b are its internal structure schematic diagrames.Wherein, the thread hob paper shredder comprises two cutter shafts 19 that are installed in the band blade 20 between two gripper shoes 21,17, the inner face of gripper shoe 17 is installed motor 18, installs between a motor and the cutter shaft 19 a pair of travelling gear 22 is installed between 16, two cutter shaft 19 other ends of train of reduction gears.

Paper-advance unit comprises the spool 8 with two rubber wheels 6 that is installed between the

biside plate

13,24, paper platform 23 is arranged below the spool 8, the handing-over line of two hobboing cutters of paper platform height and thread hob paper shredder is approaching, the back of spool 8 is obliquely installed backboard 10, spool one end is installed train of reduction gears 15 and paper feed motor 14, and the corresponding position with described rubber wheel 6 on the backboard 10 is provided with block rubber 7.Described paper-advance unit has the paper of choosing device 3, select paper device 3 to have the paper of choosing push rod 12, select paper push rod 12 to be installed in the notch 11 on the side plate 13, select paper push rod lower end and described backboard 10 fixing, select paper push rod upper end to pass from the upper port of described notch, before and after stir and select the paper push rod can change the angle of inclination of backboard, to select what of paper feed number.

Paper box 1 contains the casket body, and there is cover casket body front, and lock-switch 2 is installed between cover and the casket body.Lock-switch 2 adopts the automatic control lock-switch, has lock body and dead bolt, is provided with in the lock body and can controls the electromagnetic controller that lock-switch is opened or closed, and electromagnetic controller is to be controlled by the paper inductor 9 that is installed in above the described paper platform 23.Paper inductor 9 can adopt infrared, photoelectric sensor commonly used etc.
