[0002] The slitting machine can be used to slit metal coils such as strip steel, stainless steel, copper, etc. It is mainly used in steel processing plants, steel market operators, steel rolling mills, electrical industry, automobiles, stamping parts, etc.

[0003] At present, the patent number "CN216227269U" discloses a knife holder for a slitting machine, including a roller and an adjustment device. The surface of the roller is provided with multiple adjustment devices, and the adjustment device includes two main rings. The inner walls of the two main rings are slidably connected to the outer surface of the roller. The side walls of the main rings are movably connected to a secondary ring. The inner wall of the secondary ring is movably connected to the outer surface of the roller, and the secondary ring and the main ring form a group of two. Cutters are installed at one end of the two groups of secondary rings and the main ring that are close to each other. The inner walls of the main ring and the secondary ring are provided with anti-skid devices. The anti-skid devices include a first ring. The outer surface of the first ring is movably connected to the inner wall of the secondary ring. The side wall of the first ring is slidably connected to a second ring.

[0004] However, when the blades used on some existing tool holders are used to slit some steel coils, because the slitting blades and the steel coils are both made of metal and the two are constantly rubbing against each other during the slitting process, the high friction and high temperature generated during high-speed rotation will cause wear on the slitting blades. When the blades are worn, burrs will appear on the steel coils after slitting, which will affect the quality of the steel coils after slitting to a certain extent. Utility Model Content

[0016] Beneficial Effects

[0017] The utility model provides a slitting machine knife frame structure. Compared with the prior art, it has the following beneficial effects:

[0018] (1) The slitting machine knife holder structure is started by setting a circulating air pump, so that the gas enters from the opening of the protective cover, and then passes through the chip outlet, the air outlet cover, the chip air pipe, the functional box in turn, and enters the air guide pipe from the air inlet bin of the functional box. Finally, through the cooperation between the provided blowing cover and the blowing hole, the gas can be sprayed onto the slitting blade, thereby achieving a certain heat dissipation effect on the slitting blade and preventing the steel coil from having burrs. Among them, the semiconductor refrigeration sheet is provided to cool the air sent in, so as to achieve a better cooling and heat dissipation effect. By setting the air blowing hood into a trapezoid, the air outlet can blow off the debris on the slitting blade during the air outlet process, and the blown-off debris will pass through the chip outlet, the air outlet hood and the chip air duct, so that the debris will be collected in the functional box and blocked by the filter net and collected in the chip collecting box.

[0028] The heat dissipation assembly includes an air blowing hood 7 disposed in the protective cover and located on both sides of the slitting blade 4. The air blowing hood 7 is provided with a plurality of air blowing holes 8 for blowing air to dissipate heat for the slitting blade 4. The air blowing hood 7 is connected to the function box 6 through an air guide assembly.

[0029] Among them, the functional box 6 is divided into a chip collection bin 10 for collecting debris and an air intake bin 11 by a filter screen 9, and a semiconductor refrigeration plate 21 for cooling is provided in the air intake bin 11; wherein the semiconductor refrigeration plate 21 is a prior art, wherein the cooling surface of the semiconductor refrigeration plate 21 is arranged in the air intake bin 11, and the heat dissipation surface is exposed to the external air environment.
