Therefore, ultrasonic knife cutting is used to cut the green roll. The key to the cutting effect lies in the quality of the ceramic blade when cutting the green roll. At present, the ceramic knife grinding machine on the market can only grind a single piece, and cannot process multiple blades at one time. The batch processing efficiency is slow. In addition, most of the ceramic knife grinding machines on the market currently use manual loading, which cannot guarantee the consistency of the processing angle, resulting in inconsistent sharpening effects, affecting the quality stability of the processing. Affected by the physical strength of the workers, the processing efficiency will gradually decrease. For this reason, we need a ceramic knife grinding single-sided sharpening device with multi-directional grinding function to improve the surface quality of the ceramic blade and improve production efficiency.

Multi-directional grinding is provided to make the surface quality of the ceramic cutting edge better and the cutting edge sharper. After the grinding unit grinds one end face of the blade, the clamping fixture is adjusted to fix the blade at another preset angle, and then the other end face of the blade is ground. After the grinding is completed, the rotating motor and the grinding unit stop working, the clamping fixture returns to the initial angle, and the blade is released. The loading unit takes out the blade and sends it to the laser cutting area for scribing and cutting.

[0010] After the clamping fixture clamps the blade, the lower grinding motor and the rotating motor are started, and the lower grinding disc drives the central gear to rotate, accelerating the planetary gear movement composed of the central gear, the center wheel, and the outer gear to improve the grinding efficiency. The lower grinding cylinder gradually pushes the lower grinding slider upward to allow the lower grinding disc to grind and sharpen the single side of the lower end of the blade. After the single-sided grinding of the lower end of the blade is completed, the lower grinding cylinder pulls down the lower grinding slider to stop grinding the single side of the lower end of the blade, adjust the clamping fixture to fix the blade at another preset angle, grind the single side of the upper end of the blade, start the upper grinding motor, and the upper grinding cylinder gradually pushes down the upper grinding slider, and the upper grinding disc grinds and sharpens the single side of the upper end of the blade. After the grinding is completed, the upper grinding cylinder pulls up the upper grinding slider, and the lower grinding motor and the rotating motor turn the clamping fixture back to its original position and then stop working.

[0011] Furthermore, the upper grinding disc includes an upper grinding disc body, an upper grinding disc spring and an upper grinding disc plate, the grinding surface of the upper grinding disc body is provided with a hole, the hole on the grinding surface of the upper grinding disc body coincides with the central axis of the upper grinding disc body, the upper grinding disc spring is arranged in the hole on the grinding surface of the upper grinding disc body, one end of the upper grinding disc spring is fixedly connected to the upper grinding disc body, the other end of the upper grinding disc spring is fixedly connected to the upper grinding disc plate, and the upper grinding disc plate is slidably connected to the upper grinding disc body.

[0012] When the upper grinding disc body grinds the upper end of the blade, it gradually approaches the central gear, and the central gear abuts against the upper grinding disc plate.

[0013] Furthermore, the lower grinding disc includes a lower grinding disc body, a lower grinding disc spring and a lower grinding disc plate, the grinding surface of the lower grinding disc body is provided with a hole, the hole on the grinding surface of the lower grinding disc body coincides with the central axis of the lower grinding disc body, the lower grinding disc spring is arranged in the hole on the grinding surface of the lower grinding disc body, one end of the lower grinding disc spring is fixedly connected to the lower grinding disc body, the other end of the lower grinding disc spring is fixedly connected to the lower grinding disc plate, the lower grinding disc plate is slidably connected to the lower grinding disc body, and the lower grinding disc plate is fixedly connected to the center gear.

[0014] Because the center gear and the idler wheel are meshed, when rotating at high speed, the center gear will not move as the lower grinding disc body continues to approach the blade. The center gear presses against the lower grinding disc plate. At this time, the lower grinding disc spring is pressed down, so that the lower grinding disc body can continue to rise and completely grind the blade.

[0015] Furthermore, the clamping fixture includes a clamping seat, a stainless steel positioning scale, a clamping cylinder, a clamping motor, a baffle and a connecting rod.

When the loading unit sends the blade to the clamping fixture, the blade falls from the gap of the stainless steel positioning scales and falls onto the baffle. The bottom ends of all blades are on the same horizontal plane. The clamping cylinder pushes the stainless steel positioning scales so that the stainless steel positioning scales tilt and clamp the blades. The clamping motor starts to rotate the baffle to both sides of the clamping seat, and then the lower grinding disc grinds the blades. After grinding, the clamping motor starts to rotate the baffle to its original position, and the clamping cylinder pulls the stainless steel positioning scales so that the stainless steel positioning scales tilt and clamp the blades. The clamping motor starts to rotate the baffle to both sides of the clamping seat, and then the upper grinding disc grinds the blades. After grinding, the clamping motor starts to rotate the baffle to its original position, and the clamping cylinder resets and stops working, returns the stainless steel positioning scales to their original position, releases the blades, and waits for the clamping and conveying of the loading unit.

[0017] Furthermore, through holes are provided at both ends of the clamping seat.
