Further optimization is carried out on the basis of the embodiment:

as shown in fig. 1 and 4, in order to fix the cutter quickly, clamping plates 12 are arranged on two sides of the cutter groove 91; a fixing frame 11 is arranged on the periphery of the clamping plate 12; the two sides of the fixed frame 11 are in threaded connection with clamping bolts 10; the clamping screw 10 is terminated against the corresponding clamping plate 12. The junction of the lower end of the clamping plate 12 and the box body 1 is provided with a strip-shaped groove, when the rotary clamping bolt 10 moves forwards, the clamping bolt 10 can push the clamping plate 12 to extrude inwards, and the knife face of the knife is clamped and fixed.

As shown in fig. 1 and 6, a convex ring 51 is arranged at the center of the rotating shaft 5; a spring groove 81 is formed in the inner side of the grinding wheel 8; the compression spring 3 is sleeved on the rotating shaft 5, one end of the compression spring abuts against the spring groove 81, and the other end of the compression spring abuts against the convex ring 51.

As shown in fig. 1 and 6, a pressing cover 7 is sleeved on the rotating shaft 5 to press the outer side surface of the grinding wheel 8; a fixed nut 6 is connected to the rotating shaft 5 through threads and presses the pressing cover 7; a positioning hole 83 is annularly formed in the outer side surface of the grinding wheel 8; the inner side surface of the pressing cover 7 is provided with a positioning pin 14 for inserting into the positioning hole 83. When the fixing nut 6 is rotated, the pressing cover 7 can press the grinding wheels 8, so that the compression spring 3 is pressed, and therefore, the gap between the two grinding wheels 8 can be reduced, and the grinding tool is suitable for grinding tools with different blade surface thicknesses.

As shown in fig. 6, grinding wheel mounting shafts 52 are arranged at two ends of the rotating shaft 5; and clamping grooves 53 which are matched with the inner hole of the pressing cover 7 and used for limiting the rotation of the pressing cover 7 are uniformly arranged on the grinding wheel mounting shaft 52 in an annular shape. The grinding wheel 8 is sleeved on the grinding wheel mounting shaft 52 and fixed; the end of the grinding wheel mounting shaft 52 is connected with a threaded section 54, and the threaded section 54 is used for mounting the fixing nut 6; the end of the threaded section 54 is connected with a sliding shaft section 55, the sliding shaft section 55 is used for installing a bearing, and the bearing is installed on the bracket 2; the end of the sliding shaft section 55 is connected with a mounting section 56, and the mounting section 56 is used for mounting a nut for fixing the rotating shaft 5 on the bracket 2.

As shown in fig. 1 and 3, the sliding plate 9 is provided with isolation plates 15 at both sides below. The isolation plate 15 can improve the safety of the equipment and can play a role in isolating scrap iron.

As shown in fig. 1 and 2, a slag discharge port 19 is arranged at the bottom of the end head of the grinding cavity 17; windows 21 are provided on both sides of the grinding chamber 17. The slag discharge port 19 can discharge the polished scrap iron; the window 21 can be provided with an openable door cover, and the device can be maintained after the window 21 is opened; or the window 21 is provided in a transparent structure for the user to observe the operation state of the internal device.

The working principle of the device is as follows:

as shown in fig. 7, a knife edge of a knife 20 is horizontally inserted into the knife slot 91, the middle part of the knife edge freely falls into the gap 13 through gravity, the clamping bolts 10 on two sides are rotated without pressing, so that the knife is clamped by 20 times, then the motor 18 is started to drive the grinding wheel 8 to rotate, the V-shaped gap of the grinding wheel 8 polishes the knife edge at a high speed, and during polishing, an operator pushes the sliding plate 9 back and forth, so that the polishing surface of the grinding wheel 8 polishes the whole knife edge of the knife 20 once; before pre-polishing, an operator can wet the edge of the cutter 20 or wet the grinding wheel 8 to form water lubrication, so that the polishing fineness of the edge of the cutter is improved. Since the grinding wheel 8 is rotated at a high speed, the resistance to grinding is relatively small, and the user can easily push the sliding plate 9 back and forth.

Because the device utilizes the grinding wheel 8 rotating at high speed to grind, an operator can finish grinding the whole surface of the cutting edge by almost ensuring that the grinding wheel 8 can grind the whole surface of the cutting edge once.

For some duller tools, when the knife edge of the tool 20 is inserted horizontally into the knife slot 91, a slight manual pressure may be applied to cause the middle of the knife edge to fall into the gap 13.
