A bevel gear-shaped grinder 12 is installed at the output end of the motor 11. The material of the grinder 12 is alloy steel such as tungsten steel. The grinding of tungsten steel and the high-speed rotation of the motor 11 can reduce the generation of burrs on the tool. A housing 2 is provided on the top of the work box 1 to cover the motor 11 and the grinder 12. An installation notch 21 is opened on the housing 2. A rotating door 22 covering the installation notch 21 is hinged on the installation notch 21, and a handle 23 is installed on the rotating door 22.
[0035] Reference Figure 1 A mobile driving device is provided on the top of the working box 1 on one side of the housing 2. The mobile driving device is an electric cylinder 3. A mounting block 31 is fixedly installed on the top of the output end of the electric cylinder 3. A notch 311 for the tool to pass through is opened on the mounting block 31 toward the housing 2. Figure 3 A moving groove 24 is provided on the side wall of the housing 2 near the electric cylinder 3, and the moving groove 24 is used for the tool to move horizontally.
[0036] Reference Figure 1 and Figure 2 When in use, it is necessary to first start the motor 11 to rotate the grinder 12, and then pass the tool through the notch 311 and the movable groove 24 into the housing 2 in sequence. After the tool is adjusted to a suitable cutting position, the electric cylinder 3 is started to move the mounting block 31 horizontally, thereby driving the tool to move horizontally, so that the tool collides with the grinder 12, and the tool is ground by the grinder 12.
[0037] Reference Figure 3An upper clamping cylinder 312 is provided on the upper end surface of the mounting block 31, and a first guide port 32 is opened on the moving path of the output end of the upper clamping cylinder 312 of the mounting block 31, the first guide port 32 is communicated with the notch 311, and the output end of the upper clamping cylinder 312 is fixedly installed with an upper clamping plate 3121 through the first guide port 32; a side clamping cylinder 313 is provided on the side wall of the mounting block 31, and a second guide port 33 is opened on the moving path of the output end of the side clamping cylinder 313 of the mounting block 31, the second guide port 33 is also communicated with the notch 311, and the output end of the side clamping cylinder 313 is fixedly installed with a side clamping plate 3131 through the second guide port 33. Usually, the side clamping cylinder 313 is started first to clamp the tool inserted in the notch 311 laterally, and then the upper clamping cylinder 312 is started to clamp the tool vertically. The movement sequence of the side clamping cylinder 313 and the upper clamping cylinder 312 is realized through PLC control.
[0038] Reference Figure 2 The working box 1 is provided with a screw nut transmission mechanism 4, and a baffle 41 is vertically provided on the output end of the screw nut transmission mechanism 4. Figure 3 The baffle plate 41 is located between the mold 12 and the motor 11, and the top of the baffle plate 41 is set as an inclined surface. The design of the inclined surface can make the metal chips falling on the top of the baffle plate 41 slide to the top of the working box 1. The output end of the screw nut transmission mechanism 4 can be adjusted by screwing the input end of the screw nut transmission mechanism 4, so that the position of the baffle plate 41 can be adjusted according to actual processing needs.
[0039] Refer to 2 and Figure 3 First, the tool is passed through the notch 311 and the movable groove 24 in sequence to reach the shell 2, and then the tool will be limited by the baffle 41, and then the side clamping cylinder 313 is started according to the PLC program so that the output end of the side clamping cylinder 313 drives the side clamping plate 3131 to clamp the tool horizontally. At the same time, the clamping process also has a calibration function, and then the upper clamping cylinder 312 is started so that the output end of the upper clamping cylinder 312 moves downward, thereby driving the upper clamping plate 3121 to clamp the tool in the vertical direction. At this time, the clamping work of the tool is completed.
[0040] Reference Figure 3 The mounting block 31 is provided with a first sensor, model DMSG-N020, for detecting whether the tool is clamped by the output end of the upper clamping cylinder 312.

[0043] Reference Figure 2 After the grinding of the tool is completed, the first jet pipe 13 will start to spray jets toward the grinding tool 12 to blow off the metal chips, and the second jet pipe 14 will also start to blow off the metal chips on the tool at the same time, and then several jet holes 1511 will start to spray jets, and the blown-off metal chips and the metal chips that originally fell on the top of the working box 1 after grinding will be together under the action of the airflow ejected from the jet holes 1511 to reach the funnel-shaped chip removal channel 16, and fall into the chip removal pipe 17 under the action of gravity, and finally enter the dust collector 18 to be collected.
[0044] The implementation principle of a safe and environmentally friendly intelligent automatic knife sharpener in the embodiment of the present application is as follows: before processing, it is necessary to close the rotating door 22 and then start the rotating drive device to rotate the mold 12, and then drive the output end of the mobile drive device to reset. At this time, the tool is passed through the notch 311 and the movable groove 24 in sequence into the shell 2. The tool entering the shell 2 will be against the baffle 41 and be limited. Then, the upper clamping cylinder 312 and the side clamping cylinder 313 are started to clamp the tool. After the tool is clamped, the mobile drive device is started again, so that the output end of the mobile drive device moves laterally with the mounting block 31, thereby driving the tool located in the mounting block 31 to move laterally until it collides with the mold 12 to gradually complete the grinding.
[0045] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
