In order to meet the requirements of versatility, the rollers of the traditional sharpening machine are usually set to an adjustable mode, so that it is suitable for metal sharpening operations of various specifications. For example, the Chinese utility model patent application number is 202120008590.8, which publishes an easy-to-adjust sharpening machine, which adjusts the height of the slider by screwing the fixing screw at the upper end, thereby increasing or reducing the distance between the No. 1 roller and the No. 2 roller, which is convenient for people to adjust and use. However, since the power transmission of the No. 1 roller and the No. 2 roller of the sharpening machine is connected by two gear meshing transmissions, when adjusting the relative distance between the No. 1 roller and the No. 2 roller, it is difficult to ensure the meshing degree of the two gears, so it is necessary to replace the gears accordingly and adjust them accurately to achieve the same power transmission effect. As a result, the adjustment of the sharpening machine is difficult, the operation is complicated, and the cost of use is higher during use. Utility Model Content

[0003] In view of the problem that when the existing pointing machine adjusts the relative distance between the rollers, its power transmission mechanism also needs to be replaced and readjusted accordingly, which leads to great difficulty in adjustment, complicated operation and high cost of use, the utility model provides a new pointing machine, when the relative distance between the rollers is adjusted, its transmission mechanism does not require additional adjustment, the adjustment is time-saving and labor-saving, convenient and quick, and saves use cost.

[0005] It is further characterized in that: a driving servo hydraulic cylinder is provided on the top of the mounting bracket, and the output end of the driving servo hydraulic cylinder is connected to the connecting plate at the upper end of the movable sharpening roller;

[0006] Two adjustment seats are provided on the mounting bracket corresponding to the two roller shafts of the movable sharpening roller, and sliding adjustment blocks are provided on the two adjustment seats. The top ends of the two adjustment blocks are connected by a connecting plate, and the roller shaft of the movable sharpening roller is connected to the adjustment block through a bearing seat, and the connecting plate is connected to the piston rod outputted by the driving servo hydraulic cylinder;

[0007] A movably connected guide rod is provided through the top of the adjustment seat, and the lower end of the guide rod is connected to the adjustment block;

[0008] A connecting block is provided between the coupling and the coupling telescopic rod, the coupling is connected to the connecting block via a horizontal axis, and the coupling telescopic rod is connected to the connecting block via another vertical axis.

[0009] After adopting the above structure, since the power driving mechanism connected to the movable sharpening roller and the fixed sharpening roller is a power motor, a reducer and a gear distribution box, the gear distribution box distributes the power and then transmits it to the movable sharpening roller and the fixed sharpening roller respectively through the coupling and the coupling telescopic rod. By adopting this method, when the relative distance between the two rollers is adjusted in time, the power driving mechanism can be adjusted accordingly, which is convenient to adjust, saves time and effort, and saves use cost.

[0013] As 1 to Figure 3 As shown, a new type of sharpening machine includes a mounting bracket 1 at the lower end, and one side of the upper end of the mounting bracket 1 is provided with an upper and lower movable sharpening roller 2 and a fixed sharpening roller 3 opposite to each other. A driving servo hydraulic cylinder 9 is installed on the top of the mounting bracket 1, and the output piston rod of the driving servo hydraulic cylinder 9 is connected to the connecting plate at the upper end of the movable sharpening roller 2.

[0014] By driving the servo hydraulic cylinder 9, the movable sharpening roller 2 can be driven to move up or down to adjust the height, so that the distance between the two sharpening rollers can be adjusted to be suitable for the sharpening treatment of materials of different specifications. A power drive mechanism connected to the fixed sharpening roller 3 and the movable sharpening roller 2 is provided on the other side of the mounting bracket 1, and the two sharpening rollers are driven to rotate by the power drive mechanism to perform sharpening treatment on the materials. Specifically, the power drive mechanism includes a power motor 4 fixedly connected to the mounting bracket 1, and the output end of the power motor 4 is connected to the main belt drive wheel. The mounting bracket 1 is also provided with a reducer 5, and the input end of the reducer 5 is connected to the slave belt drive wheel, and the main belt drive wheel and the slave belt drive wheel are connected by a belt. The output end of the reducer 5 is connected to the input end of the gear distribution box 6, and the output end of the gear distribution box 6 includes two, and is respectively connected to one end of the coupling telescopic rod 8 through a coupling 7, and the other ends of the two coupling telescopic rods 8 are respectively connected to the roller shafts of the fixed sharpening roller 3 and the movable sharpening roller 2 through another coupling 7. A connecting block 10 is provided between the two ends of the coupling 7 and the coupling telescopic rod 8, and one end of the coupling 7 is connected to the connecting block 10 through a horizontal axis 11, and one end of the coupling telescopic rod 8 is connected to the connecting block 10 through another vertical axis 12. Since the connecting block 10, the horizontal axis 11, and the vertical axis 12 are provided between the coupling 10 and the coupling telescopic rod 8, a universal connection can be achieved.

[0015] The power motor 4 and the reducer 5 provide rotational power, which is distributed to the fixed sharpening roller 3 and the movable sharpening roller 2 through the gear distribution box 6. Since the gear distribution box 6 is connected with the fixed sharpening roller 3 and the movable sharpening roller 2 through the coupling 7 and the coupling telescopic rod 8, it provides power for material rolling and can also meet the requirements of driving the movable sharpening roller to adjust its upper and lower positions;

[0016] The piston rod of the driving servo hydraulic cylinder can drive the connecting plate to move, and the connecting plate drives the adjusting block to move along the guide rail. The adjusting block drives the movable sharpening roller to move through the bearing seat, so that the relative distance between the two sharpening rollers can be adjusted arbitrarily, and the power driving mechanism is also adjusted accordingly, which is convenient to adjust, saves time and effort, and saves use cost.

[0017] Two adjusting seats 13 are provided on the mounting bracket 1 at the two roller shafts corresponding to the movable sharpening roller 2, and slidingly matched adjusting blocks 14 are provided on the two adjusting seats 13.
