Abstract
The invention relates to a paper feeding safety device for a paper shredder, which is characterized in that a limiting plate for regulating the width of the paper feeding opening is fixedly arranged at the position of the paper feeding opening of the front cover of the paper shredder. The width of the paper feeding opening of the paper shredder is regulated by the cooperation between the limiting plate and the paper feeding opening so as to prevent more pieces of paper are fed; meanwhile, a mold production problem is solved. According to corresponding products, the control circuit in the prior art can be simplified, an overload protective circuit is not required and usually, physical protection does not have the fault problem of electronic protection; and thus, the safety is higher, production cost can be reduced, the product design is simpler and the production is more convenient.
Description
Technical field
The present invention relates to a kind of shredder, relate in particular to a kind of paper feed safety device of shredder.
Background technology
Present shredder paper feed port generally all is to be principle to meet safety, thus there is not the design of too many attention product itself, as long as it is just passable to meet the safety of exported country, such as UL, CE or the like; At present; shredder is in order to make the life-span of product longer; generally all be provided with overload protection function; if putting more paper, paper feed port enters; machine just is easy to damage like this; simultaneously the motor of shredder also will strengthen, otherwise the broken paper that do not go down may also move back the phenomenon of not returning can occur letting slip many paper the time, and machine just can not have been worked like this.
Along with updating of technology, (publication number is: 201516372U as Chinese utility model patent, open day be: 2010.06.30) a kind of paper feed port device with limit paper, advancing to be provided with a paper-advance unit above the paper feed port thereupon, in paper feed, grow excellent paper feeds by two guiding, the guide rod next door is supported by the elasticity thing, and is connected with the pressure handle of the microswitch of controlling the shredder electrical source of power.When surpassing the tatter amount that the maximum of loom own can bear, thereby guide rod can promote the power source that microswitch cuts off shredder.Though suppressed the paper sheet thickness of single shredded paper, but used power source, the Electronic Protection problem that breaks down easily can be accomplished 0 fault rate substantially if be designed to physical protection.
And paper feed port originally at first is designed to mould, but because mould paper feed port part will be done very thinly, that such mould just is easy to bad, and the efficient of producing can be very low, processing cost can be very high, and the product of producing also has no idea 100% to reach designing requirement, produces and just has no idea to repair, and production cost is just higher like this.
Summary of the invention
The objective of the invention is to solve the problem that prior art exists, the paper feed safety device of the shredder that a kind of paper feed port width can adjust according to the requirement of product be provided, by limiting plate can physics reach and prevent from the purpose of transshipping to have made things convenient for production.
Concrete technical scheme of the present invention: a kind of paper feed safety device of shredder is characterized in that: be provided with a limiting plate of regulating the paper feed port width at the paper feed port place of the cover of shredder, described limiting plate is fixedly mounted on described cover paper feed port place.
Have the corresponding spacing hole of connecting hole of a row or above and described cover on the described limiting plate, by described spacing hole and cooperating of described connecting hole regulating the paper feed port width.
Described cover paper feed port place is provided with the corresponding connecting hole of spacing hole of a row or above and described limiting plate, by described connecting hole and described cooperating of spacing hole regulating the paper feed port width.
The adjustable range of described paper feed port width is 1-3 a times of maximum paper-passing quantity.
Spacing hole on the described limiting plate is preferably three rows, forms at least one and regulates shelves; Connecting hole on the perhaps described cover is preferably three rows, forms at least one and regulates shelves.
The invention has the beneficial effects as follows: reach by the width of regulating limiting plate and cooperating of paper feed port the shredder paper feed port and prevent from too much to fill in paper; solved the problem that mould is produced simultaneously; can be according to corresponding product simplification control circuit of the prior art; the cancellation overload protecting circuit; and the failure problems of Electronic Protection can not appear in physical protection basically, and security is higher, also can reduce production costs; the design of product simultaneously is more simple, produces more convenient.
Description of drawings
Fig. 1 is the structural representation of embodiments of the invention 1;
Fig. 2 is the structural representation of embodiments of the invention 2.
The specific embodiment
Below, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in Figure 1, 2, a kind of paper feed safety device of shredder, be provided with a limiting plate 3 of regulating the paper feed port width at cover 1 paper feed port 2 places of shredder, described limiting plate 3 is fixedly mounted on described cover paper feed port 2 places, and the adjustable range of described paper feed port 2 width is 1-3 a times of maximum paper-passing quantity; As maximum broken 10, that is just regulated at (10*0.1=1MM) 1MM between the 3MM if paper thickness is 0.1MM..
Regulate the paper feed port width two kinds of settings arranged:
Embodiment 1, as shown in Figure 1, on described limiting plate 3, have a row or an above spacing hole 4, in the present embodiment three rows, form three and regulate shelves, described cover is provided with row's connecting hole, and connecting hole is corresponding with spacing hole, and the spacing hole 4 by mobile limiting plate makes described spacing hole and cooperating of described connecting hole regulate the paper feed port width; Each gear correspondence is the shredder motor accordingly, thereby has protected the operate as normal of shredder, has prolonged the service life of shredder;
This spacing safety device; shredder can remove to simplify control circuit according to corresponding product; cancel original overload protecting circuit, directly just can reaching of physics prevent from too much to fill in paper, solved the problem that mould is produced simultaneously with limiting plate; and the essentially no fault of physical protection; more safe, also can reduce production costs, the design of product is more simple simultaneously; underproof product can not occur in process of production, thereby make that production is more convenient.
Though preferred embodiment of the present invention is disclosed with the purpose as illustration, it will be appreciated by those skilled in the art that various modifications, interpolation and replacement are possible, as long as it does not break away from the spirit and scope of the present invention that describe in detail in the claims.
