Description

[Detailed Description of the Invention] The present invention provides a novel cutting machine with good sharpness that is used for laminating multiple sheets of paper, vinyl sheets, etc. and cutting them all at once. In this example, a machine casing 2 is provided on the upper surface of the base 1, and the lower sides of both side walls 3, 3' of this machine casing 2 are cut out to open holes 4, 4 for the material to be cut. A blade receiving member 5 is buried in a location corresponding to the bottom surface of the machine casing 2, and a pair of left and right support walls 6, 6' are provided at the left and right ends of the machine casing 2, and a pair of left and right support walls 6, 6' are provided on the side surfaces of the left support wall 6. A linear guide groove 7 with a gentle downward slope to the left, and a steep slope downward to the left on the side surface of the right support wall 6', the length of which is larger than the guide groove 7, and the upper side of the guide groove 7. The line connecting the lower position of both guide grooves 7' and 7 is the surface of the blade receiving member 5, which is a linear guide groove 7' whose distance from the upper side is the same as the distance between its lower side and the lower side of the guide groove 7. The rollers 8 and 8' are loosely fitted into the guide grooves 7 and 7', and a cutter holder 9 is arranged on the side of the support walls 6 and 6' to hold the cutter. Both ends of the tar holder 9 are connected to the above-mentioned rollers 8,
8', and furthermore, a lever 10 is rotatably supported on the upper side of the right support wall 6' in the machine casing 2, and a portion between the proximal end of the lever 10 and the above-mentioned cutter holder 9. The cutter 12 is connected to the lower edge of the cutter holder 9 by a link 11, and when the lever 10 is lowered and the cutter holder 9 is lowered, the cutting edge of the cutter 12 is connected to the cutter holder 9. It is fixed in such a way that it abuts parallel to the upper surface of 5.

In the figure, 13 is a holding member that moves up and down by the up and down operation of the lever 14 to hold down the object to be cut, 15 is a safety lever that prevents the cutter holder 9 from being pushed down excessively, 16 is a guide plate, and 17 is a scale. , 18
is the fitting, 19 is the fixing screw of the fitting 18, 2
0 is the installation screw of the cutter 11, 21 is the cover, 2
2 indicates the lower limit screw of the cutter 12.

Since the present invention has the configuration as described above, the lever 10
After raising the cutter 12 to the raised position and stopping it at the same position with the safety lever 15, the object to be cut is inserted under the cutter 12, and then the safety lever 15 is released and the lever 10
When pressed down, the cutter holder 9 and the cutter 12 move in the guide grooves 7, 7' due to the action of the rollers 8, 8', which move them from the upward diagonal position to the horizontal position as shown in the imaginary line in Figure 6. The object to be cut is cut by lowering the object diagonally while straightening and moving the entire object to the left.

As mentioned above, the present invention includes a pair of left and right support walls 6 and 6' at the left and right ends of the machine casing 2, and a linear guide groove 7 with a gentle downward slope to the left on the side surface of the left support wall 6.
Also, the side surface of the right support wall 6' has a steep slope downward to the left, the length is larger than the guide groove 7, and the distance between the upper side and the upper side of the guide groove 7 is the same as that between the lower side and the guide groove 7. A linear guide groove 7' having the same distance from the lower side is provided so that a line connecting the lower positions of both guide grooves 7' and 7 is parallel to the surface of the blade receiver member 5, and these guide grooves The rollers 8, 8' are loosely fitted into the rollers 7, 7', and a cutter holder 9 is disposed on the side of the support walls 6, 6', and both ends of the cutter holder 9 are connected to the rollers 8, 8. Furthermore, a lever 10 is rotatably supported on the upper side of the right support wall 6' in the machine casing 2, and a portion near the proximal end of the lever 10 and an intermediate portion of the above-mentioned cutter holder 9 Link with 1
1, so when the lever 10 is pressed down, the cutter holder 9 and the cutter 12 are moved from the diagonal position upward to the right by the action of the rollers 8 and 8' that move in the guide grooves 7 and 7' as described above. While returning to a horizontal state, the entire body moves to the left while descending diagonally to cut the object to be cut. It is an extremely efficient cutting method that is similar to one of the secrets of kendo, such as cutting the body of a straw doll by making it small and pulling the sword toward you.
By this, a fixed plate is fixed to the side of the cutter, which is known from, for example, Japanese Utility Model Publication No. 17-8574, an inclined hole is formed in the cutter, and a shaft rod is mounted on the fixed plate in this inclined hole. This has the effect of further increasing the sharpness of the cutter compared to the previous method in which the cutter is simply lowered diagonally by engaging the cutter.
