In the figure: the cutting machine comprises a fixed seat 1, a cutting length positioning plate 2, a discharging plate 3, a spindle motor 4, a discharging hopper 5, a circular truncated cone type base 6, a positioning pressing plate pressing wheel 7, a cutting tool apron pressing wheel 8, a pressing cam 9, a cutting cam 10, a material pressing sliding plate mechanism 11, a cutting sliding plate mechanism 12, a first sliding plate 13, a second sliding plate 14, a compression spring 15, a spindle 16, a flint material 17, a material hole 18, a fixed cutter 19 and a movable cutter 20.

Detailed Description

As shown in fig. 1, the cam type flint cutting machine comprises a circular table type base 6, a main shaft 16 is installed in the center of the circular table type base 6, a pressing cam 9 and a cutting cam 10 are coaxially installed on the main shaft 16, the protruding parts of the pressing cam 9 and the cutting cam 10 are in the same direction, the protruding radian of the pressing cam 9 is longer than that of the cutting cam 10, and discharging materials are pressed before cutting. The spindle 16 is driven by the spindle motor 4. Four groups of discharging mechanisms are arranged on the periphery of the main shaft 16 on the circular truncated cone type base 6. Each group of discharging mechanisms comprises a fixed seat 1, a discharging plate 3 and a cutting length positioning plate 2 are arranged on the fixed seat 1, wherein 20 parallel material holes 18 are formed in the discharging plate 3, and flint materials 17 with the diameter of 2.2mm can be inserted into the material holes 18. And the cut length positioning plate 2 is located below the discharge plate 3 while being spaced apart from the discharge plate 3.

Four guide rods are horizontally arranged on the fixed seat 1 and extend out of the discharging plate 3. The material pressing sliding plate mechanism 11 and the cutting sliding plate mechanism 12 sequentially penetrate through the guide rod and slide back and forth along the guide rod, a compression spring 15 is arranged on the guide rod between the material pressing sliding plate mechanism 11 and the cutting sliding plate mechanism 12, and a limit nut is arranged at the end of the guide rod to prevent the cutting sliding plate mechanism 12 from sliding out.

As shown in fig. 2, the pressing slide plate mechanism 11 includes a first slide plate 13, and a positioning and pressing plate pinch roller 7 is arranged on the first slide plate 13; the cutting slide plate mechanism 12 comprises a second slide plate 14, and a cutting tool apron pressing wheel 8 is arranged on the second slide plate 14. In the rotating process of the pressing cam 9 and the cutting cam 10, the convex part of the pressing cam 9 can be in contact with the positioning pressing plate pressing wheel 7 and is tightly pressed on the pressing plate pressing wheel 7, and the convex part of the cutting cam 10 can be in contact with the cutting tool apron pressing wheel 8 and is tightly pressed on the cutting tool apron pressing wheel 8.

Here, a cutting device is arranged between the discharging plate 3 and the cutting length positioning plate 2, the cutting device comprises a fixed cutter 19 arranged on the discharging plate 3 and a movable cutter 20 arranged on the lower end of the second sliding plate 14, both the front ends of the fixed cutter 19 and the movable cutter 20 are provided with groove cutting edges corresponding to the material holes 18, and the groove cutting edges of the fixed cutter 19 and the movable cutter 20 form a closed ring. A firestone material 17 is located within the ring. When the convex portion of the cutting cam 10 presses the cutting blade holder pinch roller 8, the movable cutter 20 moves forward, the ring shrinks and cuts the flint material 17.

The positions corresponding to each group of discharging mechanisms on the circular truncated cone type base 6 are provided with openings, the lower ends of the openings are connected with discharging hoppers 5, and discharging is completed through the discharging hoppers 5.

The working principle and the process are as follows: the flint material 17 is inserted into the material hole 18 of the discharge plate 3, the spindle motor 4 drives the pressing cam 9 and the cutting cam 10 to rotate continuously, at a certain moment, the protruding part of the pressing cam 9 presses and positions the pressing plate pressing wheel 7, the first sliding plate 13 is close to the discharge plate, and the flint material 17 is pressed and positioned in the discharge plate 3. Then the convex part of the cutting cam 10 presses the cutting knife seat pinch roller 8, the movable cutting knife 20 connected with the lower end of the second sliding plate 14 is close to the fixed cutting knife 19 and cuts off the flint material 17. Subsequently, the bulge of compressing tightly cam 9, the bulge of cutting off cam 10 break away from location pressure strip pinch roller 7 respectively and cut off blade holder pinch roller 8, and location pressure strip pinch roller 7, cut off blade holder pinch roller 8 pass through the return spring return, and flint material 17 drops on cutting off length locating plate 2 because the dead weight drops downwards, drops in hopper 5 afterwards. When the convex parts of the pressing cam 9 and the cutting cam 10 rotate to the next group of discharging mechanisms, the next cut-off of the flint material is continuously finished.
