Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a shredding machine with an improved structure of a cutter mechanism so as to shred objects to be shredded into finer pieces.

(Prior Art) Conventionally, shredding machines have been provided that shred an object while advancing it using a cutter mechanism that is rotationally driven by a motor disposed within the main body. In this type of device, a cutter mechanism is constructed by, for example, meshing cutter blades provided at a certain gap between a pair of rollers arranged in parallel. Also, a shredding machine usually has only one such cutter mechanism.

(Problem to be Solved by the Invention) However, in the above method, due to the structure of the cutter mechanism, the object to be shredded is shredded into strips of a certain shape with a certain width, so after being shredded, the object is pasted. By matching, etc., it is possible to easily confirm the written contents of the object to be shredded. In addition, since the objects to be shredded have a fixed rectangular shape, they tend to be bulky, and the waste basket quickly becomes full.

SUMMARY OF THE INVENTION Therefore, the present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide an excellent shredding machine capable of shredding objects to be shredded into finer pieces and into irregular shapes.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a first cutter mechanism and a second cutter mechanism, and connects both cutter mechanisms with a guide body. did.

(Operation) The object to be shredded is first inserted into the first cutter mechanism and shredded, and then guided by the guide body and inserted into the second cutter mechanism to be shredded into thinner and irregular shapes. be done.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a main body of the shredding machine, which has an object insertion opening 2 formed on its upper surface and is provided with a power switch 3. A first cutter mechanism 4 is disposed inside the main body 1 so as to be located directly in the insertion opening 2 for the object to be shredded. The first cutter mechanism 4 includes a plurality of cutter blades 6, which are provided with a certain gap between a pair of rollers 5, 5, which are arranged in parallel so as to be rotatable. It is constructed by meshing each other. One of the rollers 5 is connected via its spindle 5a to a motor 7 which is controlled to be turned on and off by the power switch 3, thereby rotating the cutter mechanism 4. Reference numeral 8 denotes a guide body formed to be lower toward the center, and one end of this guide body, which is an upper opening edge 8a, is closely connected to the discharge port 4a of the first cutter mechanism 4. . The lower opening edge 8b, which is the other end of the guide 8, is connected to an inlet 9a of a second cutter mechanism 9 provided in the main body 1. This second cutter mechanism 9 includes a pair of rollers 10, 10, which are formed to have a smaller diameter than the rollers 5, 5 and are rotatably arranged in parallel, and the cutter blade 6. ...
It is constructed by meshing a large number of cutter blades 11° with a constant gap smaller than the gap width.

One roller 10 has a lower gear 13 of a power transmission mechanism 12 mounted on its support shaft 10a.

The power transmission mechanism 12 includes the lower gear 13 and a lower gear 14 that meshes with the lower gear 13 and is mounted on the spindle 5a of the roller 5 connected to the motor 7.
It consists of Reference numeral 15 denotes a shredded material discharge port formed on the lower surface of the main body 1, which is located directly below the second cutter mechanism 9. Note that 16 is an object to be shredded, which is the shape before being shredded by the first cutter mechanism 4. 16a and 16b are the first
This is the object to be shredded immediately after being shredded by the cutter mechanism 4 and the second cutter mechanism 9.

Next, the operation of the above configuration will be explained.

To shred the object 16, first, the main body 1 is placed in the first neck opening of a waste basket (not shown), and the power switch 3 is operated to drive the motor 7. Then, the first cutter mechanism 4 and the second cutter mechanism 9 are rotationally driven. After this, when the object to be shredded 16 is inserted into the object to be shredded insertion port 2, the object to be shredded 16 is firstly advanced and shredded into strips of a constant width by the first cutter mechanism 4. This becomes the object to be shredded 16a. The object to be shredded 16a is discharged downward from the discharge port 4a, and is guided by the guide 8 to reach the entrance 9a of the second cutter mechanism 9. Here, depending on the shape of the guide body 8, the objects to be shredded 1.68 are in various states such as overlapping at the entrance portion 9a or being in an inclined state. Therefore, the object to be shredded 16a entering the second cutter mechanism 9 is shredded into thinner and irregularly shaped objects by the second cutter mechanism 9 while being advanced, thereby becoming the object to be shredded 16b. Then, the object to be shredded 16b is discharged to the outside of the main body 1 through the object to be shredded discharge port 15, thereby completing the shredding.

According to the above embodiment, the first cutter mechanism 4 and the first
A second cutter mechanism 9 that shreds the object thinner than the cutter mechanism 9 is provided, and these double-force vine mechanisms 4゜9 are connected by a guide 8, so that the object to be shredded can be shredded finer and in an irregular shape. can do. For this reason, after shredding, it is completely impossible to reproduce or confirm the written contents of the shredded object by pasting or the like, and it is possible to securely maintain the confidentiality of important documents. In addition, the material to be shredded is
After shredding, unlike the conventional method, the waste does not become bulky, so the waste basket does not fill up quickly and is easy to dispose of. Furthermore, since the first cutter mechanism 4 and the second cutter mechanism 9 use the motor 7 as a common driving source, it is also economical.

It should be noted that the present invention is not limited to the above-mentioned embodiments. For example, if the second cutter mechanism is made into a unit and can be attached and detached from the shredding machine body, it will not be necessary to make major design changes to conventional products. Moreover, the second cutter mechanism may be provided with a cutter blade and have a plurality of rollers, etc., and it goes without saying that various modifications can be made without departing from the gist of the invention. be.

[Effects of the Invention] As described above, the present invention provides the first cutter mechanism and the second cutter mechanism, and connects the double-force vine mechanism with the guide body, so that the object to be shredded can be made thinner and more compact. It has the excellent effect of being able to shred into regular shapes.
