Description

[0001] Printing paper cutting device [0001]

The present invention relates to a printing paper cutting apparatus, and more particularly, to a cutting knife and a guide ring for cutting a printing paper fed in a forward direction in accordance with a user's desired standard, And more particularly, to a printing paper cutting apparatus that smoothly cuts printing paper.

Generally, a printing paper cutting apparatus is provided with a rotary shaft, which is rotated by a motor, for cutting a printing paper conveyed in a traveling direction by a conveyor belt to a predetermined size, And a guide roller for guiding the cutting means to the rotary shaft provided at the lower portion.

1, the conventional cutting means 10 is formed in a cylindrical shape and has a shaft insertion port 12 through which an upper rotation axis R1 is inserted, which is rotatably moved in the center, A support roller 11 on which a rotary shaft 13 is formed and a shaft insertion port 15 through which an upper rotation shaft to be rotatably inserted is formed at a center thereof and a blade 16 is formed on the outer side, 17 are formed integrally with the cutting knife 14.

The conventional guide roller 20 is formed in a cylindrical shape and has a shaft insertion hole 21 through which a lower rotation axis R2 is inserted at the center and is closely attached to a blade 16 formed on a cutting knife 14 A guide contact surface 22 for guiding is formed.

However, in the conventional printing paper cutting apparatus configured as described above, the cutting means 10 is mounted on the upper rotation axis R1 and the guide roller 20 is mounted on the guide roller 20 in a state in which the guide roller 20 is mounted on the lower rotation axis R2. The knife 16 formed on the cutting knife 14 of the cutting means 10 is rotated in a state in which the knife 16 is closely attached to the intermediate point of the guide contact surface 22 formed so as to cut the printing paper fed in the advancing direction. There is a problem that the intermediate point of the guide contact surface 22 which is in close contact with the blade 16 is worn out to form a step and the edge of the blade 16 is cracked or broken.

In order to attach the cutting knife 14 to the groove 13 formed in the supporting roller 11, the cutting knife 17 formed on the cutting knife 14 is held and twisted by a predetermined distance to be mounted on the groove 13, There is a problem in that the cutter 14 can not form a source of jamming and the paper is shaken when cutting the paper, so that the cutter 14 can not be cut cleanly.

The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a printing apparatus, The cutting edge of the blade is formed to have a narrow thickness on the guide roller formed on the guide roller for guiding the cutting knife so that the end of the blade is located in the space and is floating in the aerial image Therefore, it is possible to use the blade semi-permanently by preventing the edge of the blade from being cracked or broken even when it is used for a long time.

In order to achieve the above object, the present invention is directed to an image forming apparatus including a cutting knife having a shaft insertion hole through which an upper rotation shaft is inserted at the center, a cutting knife having a blade for cutting a printing paper at an outer end thereof, And a supporting roller having a fitting protrusion formed on an outer circumferential surface of the shaft insertion hole; And a cutting insert is formed at a lower portion of the cutting means, and a shaft insertion hole through which a lower rotation shaft is inserted is formed at the center. A guide contact surface is formed at both ends so that the cutting knife is closely contacted and rotated. Wherein when a blade of the cutting knife is brought into close contact with a guide contact surface formed on the guide roller, an end of the blade is positioned in the space, A paper cutting device is provided.

The present invention has the effect of cutting the printing paper cleanly without cutting when cutting the printing paper as it is formed as a source of tension by fastening with a bolt, without having to form an incision to attach the cutting knife of the cutting means to the supporting roller.

Further, since the guide contact surface formed on the guide roller for guiding the cutting knife has a narrow thickness, the end of the blade is located away from the guide contact surface and is located in the space, floating in the aerial image. It can be used semi-permanently.

2 is a side view for explaining a conventional printing paper cutting apparatus;
3 is a perspective view for explaining a printing paper cutting apparatus according to the present invention;
4 is a perspective view for explaining a cutting means according to the present invention;
5 is a side view for explaining a printing paper cutting apparatus according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

In addition, the size and thickness of each component shown in the drawings are arbitrarily shown for convenience of explanation, and therefore the present invention is not necessarily limited to those shown in the drawings.

3 and 4, the printing paper cutting apparatus of the present invention includes a cutting unit 100 and a guide roller 200 as shown in FIG.

4, the cutting means 100 includes a shaft insertion port 111 through which the upper rotation shaft R1 is inserted, and a cutter blade 112 for cutting the printing paper is formed at the outer end thereof. (110).

The shaft insertion hole 121 is formed at the center thereof with an upper rotation shaft R1 through which the upper rotation shaft R1 is inserted. The shaft insertion hole 121 is formed with an insertion protrusion (not shown), which is inserted into the shaft insertion hole 111 formed in the cutting knife 110 122 are protruded.

In addition, bolt holes 113 and 123 are formed on one side of each of the cutter 110 and the support roller 210 so as to be bolted to each other.

The guide roller 200 is disposed at a lower portion of the cutting means 100. An axis insertion hole 210 through which the lower rotation axis R2 is inserted is formed at the center of the guide roller 200, A contact surface 220 is formed and a space groove 230 is formed between the shaft insertion port 210 and the guide contact surface 220.

When the blade 112 of the cutting knife 110 is closely attached to the guide contact surface 220 formed on the guide roller 200, the end of the blade 112 is positioned in the space groove 230, And is provided in a floating state.

3 and 4, the insertion protrusion 122 formed in the support roller 120 is inserted into the shaft insertion groove 111 of the cutting knife 110, Since the bolt holes 113 and 123 formed in the roller 210 are fastened with bolts in a state where they are disposed at positions corresponding to each other and are installed integrally on the upper rotation axis R1, It is not necessary to form a cutting edge for mounting the cutting knife 110 on the supporting roller 120. Therefore, the printing paper is cut smoothly without cutting when the cutting paper is cut.

After the guide roller 200 is installed on the lower rotation axis R2, the blade 112 formed on the cutting knife 110 is brought into close contact with the guide contact surface 220. At this time, Since the blade 112 of the cutting blade 110 is disposed in the space groove 230 and floats on the aerial surface, the blade 112 of the cutting blade 110 is worn on the guide contact surface 220, So that the blade 112 is prevented from cracking or breaking.

The technical idea of the present inventive printing paper cutting apparatus is that the same results can be repeatedly practiced. Particularly, by implementing the present invention as described above, it is possible to contribute to industrial development by promoting technological development, and it is worth protecting.
