Abstract
The utility model relates to the technical field of the paper shredder product, in particular to a draw latch device for paper shredder blade, which comprises: a long cutter shaft, a short cutter shaft, blade sets which are respectively fixed on the long cutter shaft and the short cutter shaft and are staggered with each other, one set of blades which are staggered with each other on the long or the short cutter shaft are respectively provided with a draw hook and a groove which are matched with each other. When in use of the utility model, when the paper shredder begins to shred paper, the long cutter shaft and the short cutter shaft have the trend of opening toward tow sides after being loaded because of shredding, the draw hook on the blade and the groove on the other blade form into the draw latch function, thus the intersection amount of the blade sets on the two cutter shafts can not be reduced, and the two cutter shafts can not be opened, thereby effectively protecting the blades of the paper shredder against damage. The utility model has more safety and reliability compared with the present paper shredder.
Description
Technical field:
The utility model relates to the shredder product technical field, refers in particular to a kind of buckle device that draws of kneader bar.
Background technology:
It is improper that discarded script is collected, and results in hand cramps for our work, even can cause serious consequence to managing safety.In the past all be that the way of adopt burning is collected, it not only needs the place of a burning, and can cause serious air pollution.In order to change this situation, various shredders have come out.
Employed in the market shredder is made up of paper scrap bucket, the shredder head that is fixed on the paper scrap bucket usually, wherein, is provided with cone breaker device in the head.The cone breaker device of shredder produces power resources by motor, and by transmission mechanisms such as series of gears power being reached a pair ofly has blade for shredding paper to distribute on thereon the cutter shaft group again.
See Fig. 1, usually, the cutter shaft group is made of rimmer knife axle 01, short sword axle 02, is fixed with some set of blades on the cutter shaft respectively growing, hold, and each set of blades is made of two blades 04, and between the set of blades by spacer ring 03 interval.Set of blades on two cutter shafts is interlaced, forms an intersecting area.Paper will be entered between two cutter shafts by this intersecting area, by set of blades pulverizing in relative rotation.
Because the span of cutter shaft is longer, so after paper entered intersecting area, cutter shaft produced distortion unavoidably, promptly two with cutter shaft outwards distortion respectively, to increase the spacing between the two, holds paper.See Fig. 1, curve A, B are exactly the deformation curve of rimmer knife axle 01 and short sword axle 02.
When using, if it is blocked up to enter the paper of shredder, the intersecting area that the set of blades on two cutter shafts forms will reduce, and in the cutter shaft middle part, situation is particularly evident especially.Along with paper is too much, the situation that this intersecting area disappears just might appear, and promptly long and short cutter shaft can be strutted.If continue this moment to use shredder, all will produce bigger damage to shredder.At this situation, for protection equipment, the inventor proposes the technical program.
The utility model content:
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, and a kind of buckle device that draws of kneader bar is provided, and draws buckle device by this, guarantees can not strutted between two cutter shafts, and the protection device security uses.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme: it comprises: rimmer knife axle, short sword axle, be separately fixed on the long and short cutter shaft and interlaced set of blades, in wherein being respectively arranged with drag hook and the groove that cooperatively interacts on one group of interlaced blade on the long and short cutter shaft.
The described interlaced adjacent end face of blade all offers groove, is fixed with a drag hook in the groove of one of them blade, and the coupler body of moulding falls into the groove of another blade on this drag hook.
Described blade is in the form of annular discs, and its edge forms point of a knife; Described groove is opened in the adjacent face of blade with circular pattern.
Described drag hook is plate-like, and its center offers an installing hole that is used to be installed in the blade groove, and an end of drag hook forms the coupler body that cooperatively interacts with groove.
During the utility model work; when shredder begins shredded paper; the trend that long and short cutter shaft can oriented both sides struts after stressed because of cut paper; the groove on pull hook and another blade just forms the effect of button of drawing on the blade at this moment; the crossing amount of the set of blades on such two cutter shafts just can not reduce; two cutter shafts just can not strutted, thereby have effectively protected kneader bar to avoid damaging.The utility model is with respect to present shredder, and is safer, reliable.
Description of drawings:
Fig. 1 is the structural representation of existing shredder;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the utility model drag hook position partial enlarged drawing;
Fig. 4 is the vertical view structure chart of Fig. 3;
Fig. 5 is the front view of drag hook in the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
See Fig. 2, the utility model comprises: rimmer knife axle 1, short sword axle 2, be separately fixed on the long and short cutter shaft 1,2 and interlaced set of blades.During work, motor drives rimmer knife axle 1 and the 2 relative rotations of short sword axle, and paper is by entering between the interlaced set of blades, and paper is pulverized under blade drives.
Set of blades is made of two blades usually, and blade is in the form of annular discs, and its edge forms point of a knife.In the utility model, in wherein being respectively arranged with drag hook 4 and the groove 5 that cooperatively interacts on the blade 31,32 of one group of interlaced set of blades on the long and short cutter shaft 1,2.See Fig. 3, these interlaced blade 31,32 adjacent end faces all offer groove 5, and this groove 5 is opened in the adjacent face of blade 31,32 with circular pattern.Be fixed with a drag hook 4 in the groove 5 of one of them blade 31, the coupler body 41 of moulding falls into the groove 5 of another blade 32 on this drag hook 4.
See Fig. 4,5, this drag hook 4 is plate-like, offers the installing hole 40 that can be set in annular ditch groove 5 in the middle of it, coupler body 41 is the arc corresponding with groove 5, like this behind drag hook 4 and groove 5 mutual grabs, when rimmer knife axle 1, when short sword axle 2 rotates, coupler body 41 can move smoothly, clamping stagnation can not occur.
During manufacturing, the groove 5 on the blade 31,32 can also can be made by modes such as machineds by the moulding of blade integrated punching.
During the utility model work; when shredder shredded paper when idle running; be formed with the gap between coupler body 41 parts of pull hook 4 and blade 32 inner ring grooves 5 internal spherical surfaces; be that coupler body 41 can not contact with the inner ring surface of groove 5; when shredder begins shredded paper; the trend that long and short cutter shaft 1,2 can oriented both sides struts after stressed because of cut paper; the groove on pull hook 4 and the blade 32 5 just forms the effect of button of drawing on the blade 31 at this moment; the crossing amount of the set of blades on such two cutter shafts just can not reduce; two cutter shafts just can not strutted, thereby have effectively protected kneader bar to avoid damaging.
Certainly, the above only is embodiment of the present utility model, be not to limit the utility model practical range, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
