Next, as shown in fig. 1 and 2, the servo motor 21 and the output motor 53 are synchronously started, the output motor 53 drives the output gear 52 to continuously rotate, the output gear 52 drives the other output gear 52 to synchronously rotate, and the two output gears 52 are synchronously driven by the two second belts 51 to continuously rotate the two cutting rotating shafts 33, so that the two cutting rotating shafts 33 synchronously drive the two metal cutters 4 to continuously rotate, which is the autorotation state of the metal cutters 4.
Meanwhile, the servo motor 21 starts to drive the driving shaft 2 to rotate forward first, the belt pulley 23 is driven to rotate forward synchronously through the first belt 22 when the driving shaft 2 rotates forward, the belt pulleys 23 on two sides synchronously rotate and synchronously drive the clamped steel roller to rotate through the hydraulic telescopic rods 24 and the positioning pressure plate 25 on two sides, then the driving shaft 2 drives the driving gear 28 to synchronously rotate forward, the driving gear 28 drives the two driven gears 3 on two sides to synchronously rotate reversely when rotating forward, the driven gears 3 rotating synchronously in the same direction drive the two rotating plates 32 to rotate in a forward swinging mode, and accordingly the two rotating plates 32 drive the two cutting rotating shafts 33 and the metal cutter 4 to move in the same direction under the limiting effect of the two limiting grooves 43.
In summary, after the servo motor 21 and the output motor 53 are started, the metal cutters 4 maintain a state of combining rotation and revolution, the rotation direction is unchanged, and the revolution direction is alternately reciprocated at a certain angle, so as to achieve a cutting effect that one of the metal cutters 4 rotates to cut into the interior of the steel roll in the rotation state, and the other metal cutter 4 rotates to cut out from the interior of the steel roll, wherein 'one in one out' is a cutting cycle, and in the cutting cycle, when one metal cutter 4 gradually withdraws, the rotation of the steel roll is accompanied, and at the moment, the other metal cutter 4 gradually approaches and cuts into the interior of the steel roll, and when the previous metal cutter 4 just withdraws, the cutting position just moves to the cutting position of the other metal cutter 4 along with the rotation of the steel roll, therefore, the other metal cutter 4 rotates reversely and cuts into the steel roller, the residual scraps in the previous cutting process can be just guided out and cut again during the reverse rotation cutting of the other metal cutter 4, the cycle is adopted, the efficient cutting effect simulating the cutting dynamics of the traditional hand-held electric saw is achieved by using the alternate movement of the two metal cutters 4, the automatic discharge of the residual scraps of the section is accompanied, and the cutting directions of the two metal cutters 4 and the steel roller always face the workbench 1, so that the scraps generated during cutting and the automatically discharged scraps can be automatically discharged downwards into the waste collection groove 6 arranged in an opening mode for storage, the subsequent uniform cleaning is facilitated, and the two cut steel rollers can be independently supported on the two supporting seats 26 for convenient removal.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
