Abstract

The utility model provides a novel blade for a shredder, which is applied to the field of shredders. The novel blade comprises a cutter body and a plurality of cutting parts arranged at the periphery of the cutter body, wherein each cutting part is formed by a first cutter point and a second cutter point, the first cutter points and the second cutter points are arranged in the axial direction of the cutter body, and the included angles of the first cutter points and the second cutter points are in V shapes. In the utility model, the first cutter points and the second V-shaped cutter points which form the V-shaped included angles are manufactured at the cutting parts, so that paper can be shredded by only using the blade, thereby greatly improving the production efficiency and reducing the production cost.

Description

A kind of novel kneader bar

Technical field

The utility model belongs to the shredder field, relates in particular to a kind of novel kneader bar.

Background technology

At present, the operation principle of existing shredder is to be set on the cutter shaft with cutting blade collocation spacer ring, utilizes motor and mate gear device to drive two groups of parallel and counterrotating cutter shafts, and the paper that the shearing force that utilization forms will be passed through cuts into fine strip shape.But the cutting portion of this kneader bar all is the hilted broadsword point, and promptly cutting portion has only a cusp, needs two sheet blades to cooperate to form set of blades during use, and the cutting portion on two blades forms the V-arrangement angle, so just can cut paper.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of novel kneader bar, and the point of a knife that it is V-arrangement that the cutting portion on this blade is processed with two angles uses this blade to cut paper.

The utility model is to realize like this, a kind of novel kneader bar, comprise a cutter hub and some cutting portions of being located at described cutter hub periphery, described cutting portion is made up of one first point of a knife and one second point of a knife, described first point of a knife and second point of a knife are along the axially-aligned of described cutter hub, and the angle between described first point of a knife and second point of a knife is V-shaped.

Particularly, the angle between described first point of a knife and second point of a knife is 0～180 °.

More specifically, described first point of a knife and second point of a knife form by two opposite described cutting portions of direction punching press.

More specifically, described cutter hub center offers one and wears axis hole, and described wearing is provided with the flat key that can fixedly connected with axle in the axis hole.

The novel kneader bar that the utility model provides by at V-shaped first point of a knife and second point of a knife of cutting portion place processing angle, uses this kneader bar to cut paper, has significantly improved production efficiency, has reduced production cost.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As Fig. 1～shown in Figure 4, a kind of novel kneader bar that the utility model embodiment provides, comprise a cutter hub 1 and some cutting portions 2 of being located at described cutter hub 1 periphery, described cutting portion 2 is made up of one first point of a knife 21 and one second point of a knife 22, described first point of a knife 21 and second point of a knife 22 are along the axially-aligned of described cutter hub 1, and the angle between described first point of a knife 21 and second point of a knife 22 is V-shaped.The utility model uses this kneader bar to cut paper by at V-shaped first point of a knife 21 and second point of a knife 22 of cutting portion 2 places processing angle, has significantly improved production efficiency, has reduced production cost.

Particularly, angle α between described first point of a knife 21 and second point of a knife 22 is 0～180 °, can be according to different needs of work, as the factors such as chopping degree of large-sized paper or undersized paper and paper corner dimension between first point of a knife 21 and second point of a knife 22 is set.

More specifically, the cutting portion 2 of this kneader bar adopts following mode to make: described first point of a knife 21 and second point of a knife 22 are made by two described cutting portions 2 of opposite direction punching press; Certainly, described first point of a knife 21, second point of a knife 22 also can adopt die cast with cutter hub 1.

More specifically, described cutter hub 1 center offers one and wears axis hole 11, and described wearing is provided with the flat key 12 that can fixedly connected with axle in the axis hole 11, makes things convenient for cutter hub 1 to fixedly connected with axle.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
