An object of the present invention is to provide a lifting device for a cutting blade for a paper cutting machine, which can raise and lower a cutting pressure and control an accurate operating range of the cutting blade by raising and lowering the cutting blade by operation.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention relates to a paper cutting machine that cuts a paper placed on a shelf 9 with a cutting blade 1 that moves up and down along a guide 102 fixed to the shelf 9 . A pressure cylinder 2 such as a hydraulic pressure is installed below one side, and one end of a lower rotating body 3 having an intermediate bent portion 3b pivotally supported by a rotating shaft 3a is pivotally connected to an end of a cylinder rod 2a to rotate the lower rotating body. The other end of the body 3 is pivotally connected to one end of the connecting arm 4, and the other end of the connecting arm 4 is pivotally connected to the fixing tool 8 b together with one end of the rotation control tool 5 linked to the lower rotating body 3. On the other hand, above the lower rotating body 3, another end of the upper rotating body 7 whose one end is pivotally supported by the rotating shaft 7a is connected to the other end of the connecting body 6 pivotally attached to the side of the cutting blade 1. , And the other end of the upper rotating body 7 is further pivotally connected to the operating lever 8 so as to be in -8 is a lifting device for a cutting blade for a paper cutting machine having a configuration in which any one of the fittings is fitted to the connected guide rod 8a and the fixing tool 8b and the operating lever 8 are connected via a spring 8c. Is constituted.

[0005]
In the above configuration, the upper rotating body 7 has one end connected to the side of the cutting blade 1 and the other end pivotally connected to a connecting member of the link mechanism, for example, the operating lever 8. The other end serving as a triangular point can be fixed to the end of the guide 102 for supporting the cutting blade by the rotating shaft 7a.

[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the accompanying drawings.
The lifting device for a cutting blade for a paper cutting machine according to the present invention operates a hydraulic cylinder 2 installed at a lower portion of one side of the cutting blade 1, and connects the cutting blade 1 via a link device connecting the hydraulic cylinder 2 and the cutting blade 1. Is raised and lowered to cut the paper.
That is, in the present apparatus, the guide 102 is fixed to the shelf 9 as a paper receiving table fixed to the apparatus main body, and the cutting blade 1 is arranged to move up and down along the guide.
A pressure cylinder 2 such as a hydraulic pressure is installed below one side of the cutting blade 1, and an intermediate bent portion 3 b of a lower U-shaped lower rotating body 3 is pivotally supported by a rotating shaft 3 a to the apparatus side. One end of the rotating body 3 is pivotally connected to the end of the cylinder rod 2a of the cylinder 2, the other end is pivotally connected to one end of the connecting arm 4, and the other end of the connecting arm 4 is Along with one end, it is pivotally attached to a fixture 8b disposed above the lower rotating body 3, the rotation control tool 5 clamps the lower end of the lower rotating body 3 at the other end, and the fixing tool 8b is connected to the guide rod 8a. The lower part is fitted to be able to move up and down.
[0007]
An upper rotator 7 is disposed above the lower rotator 3. The upper rotator 7 is a triangular plate. One end of the upper rotator 7 is pivotally supported at the lower portion of the guide 102 by a rotation shaft 7a. One end is pivotally connected to the other end of the connector 6 pivotally connected to the side of the cutting blade 1, and the other end of the upper rotating body 7 is pivotally connected to the operating lever 8. Is fixed to the upper end of the guide rod 8a extending downward, the coil spring 8c is loosely fitted to the guide rod 8a, the fixing tool 8b is fitted to the lower part of the guide rod, and both ends of the spring 8c are respectively actuated by the operating levers 8. And the fixture 8b, and by connecting the two 8, 8b, the up-and-down distance of the cutting blade 1 can be controlled.
[0008]
That is, as shown in FIGS. 3 and 4, when the cylinder rod 2a of the hydraulic cylinder 2 rises, the lower rotating body 3 having one end pivotally connected to the cylinder rod 2a rotates around the rotating shaft 3a to the other end. The connecting arm 4 connected to the shaft is pulled, but the vertical movement of the connecting arm caused by the vertical movement of the cylinder rod 2a is pivotally attached to the connecting portion 5b of the connecting arm 4 and the other end is located at the intermediate portion of the lower rotating body 3. By means of the rotation control tool 5 holding the, a stable and constant repetitive motion can be achieved.
The connecting arm 4 pulls the fixture 8b and pulls the connected operating lever 8. The movement of the operating lever 8 rotates the upper rotating body 7, pulls the connecting body 6 connected to the other end of the upper rotating body 7, pulls the cutting blade 1, the cutting blade 1 descends, and the paper is cut. You.
[0009]
At this time, since the rotation control tool 5 controls the operation range of the operation lever 8 and realizes a stable vertical movement, the link mechanism associated with the interlocking of each connecting member can perform an accurate operation, and the cutting blade 1 cuts the paper placed on the shelf 9 while moving up and down along the guides 102 on both sides. The spring 8c has a buffer function.
As described above, when the pressure cylinder 2 such as a hydraulic pressure and the link mechanism are used, the operating range of the cutting blade 1 can be accurately controlled by adjusting the movable range of the cylinder 2. In addition to being able to precisely control the lowest point at which the blade should descend, not only can the paper be cut quite precisely, but such precise control prevents biting contact between the blade and the shelf 9, thereby preventing damage to the blade. Thus, the life of the cutting blade 1 can be extended.
[0010]
【The invention's effect】
As described above, according to the present invention, by accurately controlling the operating range of the cutting blade, it is possible to prevent the damage caused by the blade biting into and contacting the shelf, prolong the life of the cutting blade, and prevent unreasonable action. As a result, an energy-saving paper cutting machine can be obtained, and replacement and purchase costs due to breakage of the cutting blade can be reduced, thereby improving productivity.
