The present invention relates to a cutting device for shortly cutting materials such as threads and fabrics made of natural fibers and fibers and threads and fabrics made of synthetic resin, nets, strings and ropes, thin, wide or long films and plate cylinders.

In the case of cutting long, thin, thin or thin flexible materials for recycling of resources or for other uses, the conventional method is to cut the material between a single small-cutting knife and a base that is reciprocating or sawtooth such as a circular saw band saw. The blade was cut while rotating, and put into a plastic grinder to grind.

These materials are fine, flexible, elastic, etc., so that cutting by the conventional method does not cut even if the blade is cut through the underlay, or the blade and the teeth are often broken by mixed and mixed materials. In the case of tangled or melted, there was a defect.

For example, agricultural vinyl film contains a considerable amount of soil when collected after use, and is mixed with leaf and stem branches of plants and even steel parts such as wire and bolt nuts used in the assembly of the beanie house. Only after the removal process could the cutting blades be prevented from being damaged.

In the case of waste products made of synthetic resins, they are transported and stored mainly in large bags. To recycle them, they had to be removed from the bags to be cut. This work is very difficult because the fibers are entangled with each other. The blades or rotating saw blades were often damaged.

The nets are long and bulky and entangled with each other. They are attached with lead weights, buoys, rope connectors, and other small pieces of fish litter and nets that are difficult to separate and difficult to recycle. One of the materials.

In the case of fabrics such as clothes, metals are often used for buttons and jacquard ornaments, so they must be removed before cutting. In addition, thin, wide or long film plates such as strings and ropes contain club staple needles and other metal foreign substances. It should be removed before cutting.

When cutting with rotating saw blade without removing foreign materials, there is a risk of sparks and instantaneous heating and ignition of flammable materials directly due to collision and friction between metals. There was a flaw,

In addition, in the conventional method, when a large cut is made at the beginning and the fine cut is made again, the pressure is pushed by the blade so that the materials are pushed in a direction where there is no pressure, so there is no space for pressing or pushing the materials of both parts of the cutting knife together. Since it is necessary to take measures such as fine cutting at once, it has been a factor to further reduce the yield and increase the wear, damage and damage of the cutting blade.

In this situation, it is difficult or impossible to remove various foreign materials before cutting the material, so it is difficult to recycle resources and become a waste causing environmental pollution. There was a need for a high cutter.

Prior art, which is a reference for understanding the present invention, is a machine for cutting bread for toast, and a plurality of cutting knives erected in parallel are formed with equilateral triangle saw blades and are pulled taut and adjacent blades rise and fall in opposite directions to each other. It is a structure.

If you push the bread with the tool to start and push the machine, the bread will be cut cleanly by the reciprocation of the blade, but if you stop the blade and push the bread, the bread will be cut a little by the blade of the knife, By the effect of pulling the portion of bread on both sides of the bread, which is under the force of the blade, the bread is clumped and finally cut out.

According to the present invention, a plurality of cutting knives are placed in a row adjacent to an open end of a hexahedral structure, and the blades are directed toward the inside of the hexahedron. By means of intermittent press means for pushing the material toward the cutting knife, and the cube is formed into a lozenge (funnel type), and the tracks or conveyor belts inside the cube are rotated at each symmetrical or four sides. Each of the continuous indentation means for pushing the material toward the cutting knife can be used.

In addition, it is possible to use intermittent and continuous indentation means, which have a small installation space and high power effect, such as a known telescopic hydraulic cylinder, a four-ring ring cage, a wire rope and a pulley.

In addition to the fixed and fixed method, the cutting knife provides reciprocating motion in the longitudinal direction or by applying an arbitrary inclination within 30 degrees in the front or rear in a vertical or horizontal installation state to improve the cutting efficiency of the blade and to be caught on the blade. Enable to distribute the load.

And since both ends supporting the cutting knife have elastic body and sensor at the back part of the blade, if a large load is applied to the blade or a load that is damaged enough to damage the cutting knife by foreign matter, the cutting knife is pushed backward while compressing the elastic body and at the same time the signal of the sensor Due to the fluctuation, the cutter will mark the position of the emergency cut and overloaded cutting knife.

The plate is not in contact with the blade of the cutting knife but is close to it.The material of the end of the reciprocating stroke of the plate is also cut by placing a push rod that enters the space between the cutting knife on the front of the plate in contact with the material. It has the advantage of making the finish neat.

And by adding the cutting structure and method for public use to the structure and method of the present invention by pushing the material into the mill plate to cut the cutting plate at a certain distance, the mill plate is stopped and cut at right angles to the direction of progress of the material with a known cutter. By repeating the method of pushing the plate to a certain distance, the cutting in the direction of travel and the cutting in the vertical direction can be done more precisely at once, and there is a known control circuit and sensor device that automatically repeats the operation. It also has a simplified advantage.

In addition to the convenience and safety of the work in addition to the present invention, in addition to the structure of the present invention, the device for loading the material by dropping the knot or flipping the knot at the bottom of the transport device, up and down device, storage bag, The device which distributes the charged material evenly so that the cover closes well, the device which puts the cut material in the bag, the conveyor device which leads to the next process, the warning device about the overload and overheating of a drive circuit, etc. are conventional from this invention. It can be easily configured by those skilled in the art.
