[0029] The effect achieved by the entire embodiment 1 is that one of the rotating shafts 4 and the flying shear roller 41 are driven to rotate synchronously by the motor 8. When the rotating shaft 4 rotates, the two gears 9 are meshed with each other, thereby driving the two flying shear rollers 41 to rotate, and the two flying shear rollers 41 rotate in opposite directions. When the two flying shear rollers 41 rotate in opposite directions, the cutter 51 installed on the surface of the flying shear roller 41 rotates around the axis, thereby shearing the plate and strip. During shearing, by starting the chiller 2, the coolant can be transported to the water inlet pipe 21, and the coolant is diverted to the two first connecting pipes 22 through the water inlet pipe 21 and enters the water inlet shunt cover 6. Since the end of the water inlet shunt cover 6 connected to the flying shear roller 41 is in an open state, the coolant can enter the flow channel hole 43. When the coolant passes through the flow channel hole 43, it can Heat exchange is generated with the inner wall of the slot 44, and since part of the heat on the cutter 51 can be conducted to the slot 44 through the mounting plate 5, the cutter 51 is cooled, and the over-high temperature of the cutter 51 is avoided to affect the cutting performance. At the same time, the service life of the cutter 51 is improved. Afterwards, the coolant enters the water outlet manifold 7 through the flow channel hole 43, and enters the chiller 2 through the second connecting pipe 24 and the water outlet pipe 23 in turn for cooling, thereby achieving a circulating cooling effect. The chiller 2 is mainly composed of a compressor, a condenser, an evaporator, a built-in water tank, a water pump and other structures. Its working principle is to compress the refrigerant through the compressor, dissipate heat through the condenser, enter the evaporator through the throttling device, absorb heat and then return to the compressor for circulation. The device is an existing mature equipment and will not be elaborated here.

[0030] Embodiment 2, as Figure 1-Figure 6 As shown, a slot 44 is provided on the outer surface of the rotating shaft 4 near the left and right sides, a through hole 45 is penetrated through the inner wall of one side of the slot 44, a mounting plate 5 is inserted into the interior of the slot 44, a cutter 51 is fixedly connected to the outer surface of the mounting plate 5, threaded holes 52 are symmetrically penetrated through the outer surface of the mounting plate 5 near the edge, a connecting bolt 53 is connected to the inner thread of the threaded hole 52, and the connecting bolt 53 corresponds to the through hole 45, an air collecting groove 46 is penetrated through the outer surface of the flying shear roller 41 near the upper and lower sides, and one end of the air collecting groove 46 is connected to the inner wall of one side of the slot 44.

[0031] The effect achieved by the entire embodiment 2 is that the mounting plate 5 can be fixedly connected to the slot 44 by the connecting bolts 53, and is easy to disassemble, thereby facilitating the disassembly and replacement of the cutter 51. When the flying shear roller 41 is rotating, the air around the flying shear roller 41 enters the interior through the large opening of the air collecting groove 46, and then enters the slot 44 through the small opening, which plays a role in guiding and pressurizing the air, so that the airflow passes through the small opening of the air collecting groove 46 and blows toward the cutter 51, accelerating the fluidity of the air around the cutter 51, and further improving the heat dissipation effect of the cutter 51.

[0032] Working principle: When in use, the motor 8 drives one of the rotating shafts 4 and the flying shear roller 41 to rotate synchronously. When the rotating shaft 4 rotates, the two gears 9 mesh with each other, thereby driving the two flying shear rollers 41 to rotate, and the two flying shear rollers 41 rotate in opposite directions. When the two flying shear rollers 41 rotate in opposite directions, the cutter 51 installed on the surface of the flying shear roller 41 rotates around the axis, so that the plate and strip can be sheared. During shearing, by starting the chiller 2, the coolant can be transported to the water inlet pipe 21, and the coolant is diverted to the two first connecting pipes 22 through the water inlet pipe 21, and enters the water inlet shunt cover 6. Since the end of the water inlet shunt cover 6 connected to the flying shear roller 41 is in an open state, the coolant can enter the flow channel hole 43, when the coolant passes through the flow channel hole 43, it can generate heat exchange with the inner wall of the slot 44, and because part of the heat on the cutter 51 can be conducted to the slot 44 through the mounting plate 5, the cutter 51 is cooled down to avoid the overly high temperature of the cutter 51 affecting the cutting performance. At the same time, the service life of the cutter 51 is improved. When the flying shear roller 41 is rotating, the air around the flying shear roller 41 enters the interior through the large opening of the air collecting groove 46, and then enters the slot 44 through the small opening, which plays a role in guiding and pressurizing the air, so that the airflow passes through the small opening of the air collecting groove 46 to blow towards the cutter 51, accelerates the fluidity of the air around the cutter 51, and further improves the heat dissipation effect of the cutter 51.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
