Description

Technical Field

[0001] The present application relates to the technical field of knife sharpening, and in particular to a knife sharpening assembly. Background Art

[0002] In factory production, the cutting process of oil pipes is usually carried out by rotating the tool. After a long time of use, the tool will become blunt, which will affect the cutting and cause the cutting surface to be uneven. Therefore, it is usually necessary to remove the blade and manually grind the blade with a file to ensure the sharpness of the blade.

[0003] However, in the process of factory production and processing, usually multiple cutting equipment are operated synchronously, and a large number of blades that need to be sharpened at one time are generated. Therefore, people began to use sharpeners to sharpen the blades to improve the grinding efficiency. The existing sharpeners sharpen one blade at a time. After one blade is polished, it is necessary to manually replace the blade and calibrate the positioning before the next blade can be polished. The replacement and positioning process still takes a lot of time. However, in the factory, usually multiple devices need to sharpen the blades at the same time. It is troublesome to disassemble and position them one by one, which is not convenient for continuous grinding of multiple blades. Utility Model Content

[0004] In order to facilitate continuous sharpening of a blade, the present application provides a sharpening assembly.

[0005] The present application provides a knife sharpening assembly, which adopts the following technical solution:

[0006] A knife sharpening assembly comprises a mounting seat and a grinding device, wherein the grinding device is arranged on the mounting seat, a slider is slidably connected to the mounting seat, a mounting shaft is passed through the slider, a blade is detachably connected to the mounting shaft, a plurality of blades are arranged, a limiting assembly for limiting the position of the blade is arranged on the mounting shaft, a driving member for driving the mounting shaft to rotate is arranged on the mounting shaft, a first moving assembly for driving the mounting shaft to move horizontally is arranged on the mounting seat, and a second moving assembly for driving the mounting shaft to move vertically is also arranged on the mounting seat.

[0007] By adopting the above technical solution, when it is necessary to grind the blade, multiple blades can be installed on the mounting shaft at one time, and the positions of the multiple blades can be limited by the limiting assembly. Then the first moving assembly moves the mounting shaft and moves the blade to the grinding device. The grinding device starts to grind. During the grinding process, the driving member drives the mounting shaft to rotate, so that the blade located on the mounting shaft also rotates, thereby grinding all corners of the blade. When one blade is finished grinding, the first moving assembly starts again, so that the blade on the mounting shaft is misaligned with the grinding device. The second moving assembly starts, so that another blade on the mounting shaft is aligned horizontally with the grinding device, and is moved again for grinding under the action of the first moving assembly, thereby realizing continuous grinding of the blade, eliminating the disassembly and re-positioning process after each grinding, and a large number of blades can be ground at one time.

[0008] Preferably, the limiting assembly includes a first nut threadedly connected to the mounting shaft, and a second nut threadedly connected to the mounting shaft, a clamping space for clamping the blade is formed between the first nut and the second nut, and the limiting assembly is provided with multiple groups, and one group of the limiting assemblies is used to limit one blade.

By repeating this process, the installation of multiple blades can be completed.

[0010] Preferably, the first moving assembly includes an electric push cylinder fixedly connected to the mounting seat, a connecting rod fixedly connected to the piston rod of the electric push cylinder, and one end of the connecting rod away from the electric push cylinder is fixedly connected to the sliding block.

[0011] By adopting the above technical solution, through the setting of the electric push cylinder and the connecting rod, the electric push cylinder is electrically connected to the external power supply. When the slider needs to move, the piston rod of the electric push cylinder moves, driving the slider to move, thereby realizing the movement of the slider.

[0012] Preferably, a plurality of the sliding blocks are provided.

[0013] By adopting the above technical solution and setting a plurality of sliders, mounting shafts can be provided on the plurality of sliders for mounting blades for use. When the blade on one mounting shaft is polished and moved to avoid, the blade on another mounting shaft can be moved to the grinding equipment for polishing due to the synchronous movement of the plurality of sliders, thereby ensuring that the time is fully utilized for polishing and increasing work efficiency.

[0014] Preferably, a slide rail is provided on the mounting seat, a slide groove is provided on the slide rail, and the slider slides in the slide groove.

[0015] By adopting the above technical solution, the sliding of the slider is guided by the setting of the slide rail and the slide groove, which facilitates the directional sliding of the slider. At the same time, avoidance space is left for the installation shaft that is set through, making the overall design more reasonable.

[0016] Preferably, the second moving assembly includes a sliding seat slidably arranged on the mounting seat, a screw rotatably connected to the sliding seat, a connecting block threadedly connected to the screw, a positioning column fixedly connected to the sliding seat, and a first driving motor fixedly connected to the sliding seat, the connecting block is passed through the positioning column, the mounting shaft is arranged on the connecting block, and the first driving motor is used to drive the screw to rotate.

[0017] By adopting the above technical solution, the first drive motor is electrically connected to the external power supply. When it is necessary to drive the installation shaft to move in the vertical direction, the first drive motor is started to drive the lead screw to rotate. The rotation of the lead screw will cause the connecting block to move on the lead screw. The movement of the connecting block will cause the installation shaft to move together, thereby realizing the movement of the installation shaft.

[0018] Preferably, the driving member is a second driving motor fixedly connected to the connecting block, and the rotating shaft of the second driving motor is coaxially fixedly connected to the mounting shaft.

[0019] By adopting the above technical solution and setting the second drive motor, when the installation shaft needs to rotate, the second drive motor is started, and the rotating shaft of the second drive motor drives the installation shaft to rotate, thereby realizing the rotation of the installation shaft.

[0020] Preferably, a guide column is fixedly connected to the mounting seat, and the sliding seat is slidably connected to the guide column.

[0021] By adopting the above technical solution and arranging the guide column, the guide column guides the sliding of the sliding seat, thereby facilitating the directional sliding of the sliding seat.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1.

After one blade is grinded, the first moving assembly and the second moving assembly are used to exchange positions, so that the remaining blades on the mounting shaft are grinded respectively, so that the effect of installing and grinding multiple blades at one time is achieved, and the blades can be grinded continuously;

[0024] 2. Through the setting of multiple sliders, when the installation axis on one slider moves in the first moving component and the second moving component to avoid and change positions, the installation axis on the other slider will move to the grinding equipment for grinding, which greatly increases the utilization time of the grinding equipment and increases work efficiency.
