[0024] In this embodiment, one of the two sets of knife feeding mechanisms is located above the first hydraulic cylinder 3, and the other set of knife feeding mechanisms is located below the polishing mechanism. The knife feeding mechanism located above can be used to vertically transport the zirconia ceramic knife downward and gradually pass through between the two grinding rollers 5 and between the two polishing rollers 9. The knife feeding mechanism located below can be used to vertically pull the zirconia ceramic knife out of between the two grinding rollers 5 and between the two polishing rollers 9. The knife feeding mechanism includes a conveying component and a clamping and fixing component. The conveying component includes an electric guide rail 11, an electric slide 12 and a crossbeam 13.

The clamping and fixing assembly includes a U-shaped plate 14, two electric telescopic rods 15 and two clamping plates 16. The U-shaped plate 14 is fixedly mounted on the right end of the crossbeam 13.

The output shaft ends of the two electric telescopic rods 15 respectively penetrate the left wall and the right wall of the U-shaped plate 14. The two clamping plates 16 are respectively fixedly mounted on the output shaft ends of the corresponding electric telescopic rods 15. By utilizing the retractable characteristics of the two electric telescopic rods 15, the corresponding clamping plates 16 can be controlled to move horizontally and linearly, respectively, so that the spacing between the two clamping plates 16 can be adjusted. The two clamping plates 16 can be used to clamp and fix the zirconia ceramic knife.

[0025] In this embodiment, in order to improve the reliability of clamping and fixing the zirconia ceramic knife and prevent damage to the clamping part of the zirconia ceramic knife, a non-slip rubber pad 17 is fixedly installed on the side where the two clamping plates 16 are close to each other.

[0026] In this embodiment, in order to smoothly pull the zirconia ceramic knife to move linearly from top to bottom and allow the zirconia ceramic knife to smoothly pass between the two grinding rollers 5 and between the two polishing rollers 9 for grinding and polishing in sequence, the two sets of clamping and fixing components are symmetrically arranged.

[0027] In this embodiment, a dust suction pipe 18 is fixedly installed on the right outer wall of the processing box 2, and the dust suction pipe 18 is connected to the interior of the processing box 2. It should be supplemented that one end of the dust suction pipe 18 is fixedly connected to the dust suction end of an external vacuum cleaner. The suction force generated by the operation of the vacuum cleaner can be used to suck away the debris generated by the grinding and polishing of the zirconia ceramic knife.

[0028] In this embodiment, the two first hydraulic cylinders 3, the two first motors 6, the two second hydraulic cylinders 7, the two second motors 10, the two electric guide rails 11, the two electric slides 12, and the four electric telescopic rods 15 can all be purchased on the market, and their line connection methods and control methods are mature technologies in the field and are fully disclosed, so they will not be described in detail in this article.

[0029] Through the above structure, the double-sided grinding device for zirconia ceramic knives provided by the present application can realize the double-sided grinding and double-sided polishing of the zirconia ceramic knife at the same time when in use, thereby improving work efficiency. During specific operation, the zirconia ceramic knife is first placed vertically into the processing box 2 so that the top of the zirconia ceramic knife is located between the two clamping plates 16 at the top, and then the two electric telescopic rods 15 at the top are controlled to extend and operate so that the two anti-slip rubber pads 17 at the top are respectively in tight contact with the two side surfaces of the zirconia ceramic knife, and then the operation of the two electric telescopic rods 15 at the top is stopped, and the zirconia ceramic knife can be clamped and fixed on the upper U-shaped plate 1 4, and then control the upper electric slide 12 to slide downward on the upper electric guide rail 11, so as to control the clamped zirconia ceramic knife to move vertically downward. When the bottom end of the zirconia ceramic knife just moves down between the two grinding rollers 5, the sliding of the upper electric slide 12 is paused, and then the two first hydraulic cylinders 3 are controlled to extend and operate until the two grinding rollers 5 are respectively in contact with the two side surfaces of the zirconia ceramic knife, and then the two first motors 6 are controlled to operate so that the two grinding rollers 5 rotate synchronously in opposite directions, and then the upper electric slide 12 is continued to be controlled to slide downward on the upper electric guide rail 11, so that the zirconia ceramic knife can be double-sided ground at the same time;

[0030] When the bottom end of the zirconia ceramic knife just moves down between the two polishing rollers 9, the sliding of the upper electric slide 12 is suspended, and the two second hydraulic cylinders 7 are controlled to extend and operate until the two polishing rollers 9 are respectively in contact with the two side surfaces of the zirconia ceramic knife, and then the two second motors 10 are controlled to operate so that the two polishing rollers 9 rotate synchronously in opposite directions, and then the upper electric slide 12 is continuously controlled to slide downward on the upper electric guide rail 11, so that the zirconia ceramic knife can be double-sided polished at the same time, and the integrated operation of double-sided grinding and double-sided polishing is realized at this time;

[0031] When the bottom end of the zirconia ceramic knife passes through the two polishing rollers 9 to a suitable length, the upper electric slide 12 is stopped from sliding, and the bottom end of the zirconia ceramic knife enters between the two clamping plates 16 below. By controlling the two electric telescopic rods 15 below to extend and run, so that the two clamping plates 16 below tighten and fix the bottom end of the zirconia ceramic knife, the two electric telescopic rods 15 above are controlled to retract and reset, and the clamping fixation of the top end of the zirconia ceramic knife is released. Then, the lower electric slide 12 is controlled to slide vertically on the lower electric guide rail 11, and the two side surfaces of the zirconia ceramic knife can continue to be double-sided grinding and double-sided polishing in turn. When the top end of the zirconia ceramic knife completely passes between the two polishing rollers 9, the lower electric slide 12 is stopped from sliding, and the two electric telescopic rods 15 below are controlled to retract and reset, and the zirconia ceramic knife can be removed.

[0032] According to the above operating steps, the next zirconia ceramic knife can be double-sided ground and double-sided polished, and when the shape and size of the subsequent multiple zirconia ceramic knives to be processed are the same as those of the first zirconia ceramic knife, there is no need to readjust the spacing between the two grinding rollers 5 and the spacing between the two polishing rollers 9.
