Background
At present, most of cutting machines actually used in home textile, outdoor articles and packaging industries are flat-knife cutting machines, and the cut is linear. This can have a number of adverse effects, mainly: first, for textile fabric, the linear type incision for the yarn of incision department drops easily, forms batting and yarn end easily, brings the harmful effect for follow-up processing and product quality. Secondly, the linear incision is too monotonous, and for industries such as packaging, the corrugated zigzag incision can play the decorative effect, satisfies different demands of customers simultaneously. Thirdly, the linear type incision makes the yarn etc. of incision department take off easily, and in the follow-up processing, in order to prevent excessive taking off, need carry out the serging processing, increased the human cost.
People can adopt different schemes to reduce adverse effect, and current scheme is for adopting the cold cutting circular knife of sawtooth to cooperate high accuracy round steel roller to cut, or uses the ultrasonic wave principle to cooperate oscillator and tool bit to cut, forms the sawtooth incision, and the shortcoming of these two schemes is: first, the cost of manufacture is high. The manufacturing cost of the steel roller, the ultrasonic generator, the vibrator and the saw tooth cold cutting circular knife is very high. Second, the structure is complex and the failure rate is high. The common saw tooth cold cutting circular knife needs to use an air pressure device to keep a certain pressure on the steel roller by the saw tooth cold cutting circular knife; the ultrasonic scheme needs a vibrator, a knife rest, a generator and the like, has a complex structure and is easy to break down. Thirdly, the use and maintenance cost is high, the saw tooth cold cutting circular knife is directly propped against the steel roller, the saw tooth cold cutting circular knife is easy to damage and dulled, the knife cannot be sharpened, and the knife changing cost is high; the ultrasonic cutters are also prone to dulling and need to be replaced in time. Fourthly, quality problems are easy to occur, once a certain place of the sawtooth cold cutting circular knife and the ultrasonic knife becomes blunt, cutting is easy to occur, and even if a plurality of fibers are cut continuously, defects such as spinning, yarn drawing and the like are formed on the surface of the fabric due to the pulling of the fibers; and high defective rate is caused. Fifth, the energy consumption is big, and the cold circular knife of ordinary sawtooth needs pneumatic means to work, and the principle of ultrasonic wave cutter scheme is to use the electric energy to convert mechanical vibration energy to cut off, and power is all bigger, causes the electric energy loss very big.

The balancing weight is located one side of the inclined plane cutting edge 2 far away from the vertical plane of the rotating shaft of the mass center balancing weight disc 1, mass center unbalance caused by deflection of the inclined plane cutting edge 2 can be better counteracted, stability of the inclined plane cutting edge 2 during high-speed rotation is guaranteed, and vibration is not generated.
The working principle of the invention is as follows: the invention makes the plane of the bevel blade 2 form a certain angle with the vertical plane of the rotating shaft, and meanwhile, the projection of the elliptic bevel blade 2 on the vertical plane of the rotating shaft is circular. In order to prevent the violent vibration phenomenon of the bevel blade during high-speed rotation, a mass center balance weight disc 1 is designed in the opposite direction of the plane deflection of the bevel blade 2, so that the mass center of the whole rotary knife is positioned at the rotation balance position as much as possible. In this way, when the bevel blade 2 rotates at a high speed, regular swing is generated at the notch, and a corrugated sine-like saw tooth notch is generated under the cooperation of the advancing speed of the material. Thereby preventing yarn from being broken off and flock from being generated at the cut. The aim of saw-tooth cut is achieved in a simple way.
The invention has low manufacturing cost. The product has simple manufacturing process and greatly reduced cost compared with the traditional serrated circular knife. By adopting the product, the slitter and the cutting machine do not need accessories such as a matched steel roller, an ultrasonic generator, a vibrator and the like, so that the manufacturing cost is greatly reduced.
The structure is simple. The structure of the equipment using the product is greatly simplified. The saw-tooth cutting can be performed by only matching the bevel blade 2 with a certain advancing speed of the cut material. The steel roller and the air pressure component of the common sawtooth cold cutter device are removed; the generator, vibrator, tool bit frame air pressure component, vibrator mounting frame and the like of the ultrasonic wave scheme are removed.
The use and maintenance costs are low. Because the structure is simple, the maintenance is easy, the fault is not easy to happen, and the tool is not required to be replaced. Because the material is cut by the rapid rotation of the bevel blade 2, the wear on the bevel blade 2 is low. When the inclined plane blade 2 becomes blunt, the knife sharpener can be used repeatedly by grinding the knife sharpener. The traditional serrated circular knife is only required to be dull and difficult to polish, and can only be replaced. The use cost is greatly reduced compared with the prior art.
The product quality is good, the operation is stable, and the quality problem is not easy to occur. Because the product cuts the material by the high-speed rotation of the inclined plane blade 2, the material can be completely cut off, the phenomenon that partial yarns or fibers are easily cut continuously in the traditional scheme is avoided, and the stability of the product quality is ensured.
The energy consumption is low. Because the bevel blade 2 is rotated for cutting, compared with the traditional method, the power consumption is greatly reduced, and the green energy-saving effect is realized.
The function is many, can adjust the speed that the material advanced through automatically controlled parameter to adjust the size of profile of tooth at will. The purpose that one inclined plane blade 2 can cut out various effects is achieved, and the effect of function diversification is brought.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention. Any reference sign in a claim should not be construed as limiting the claim concerned.
