[0015] The application is further described below in combination with the drawings:

[0016] As shown in the drawings, Figure 1 the application provides an automatic cutter polishing mechanism applied to a slicing device. The embodiment mainly includes a cutting rotating device a and a translation polishing frame b.

[0017] As shown in the drawings, Figure 2 the cutting rotating mechanism mainly includes a cutting rotating mechanism support 1, a rotating arm 2, an x-axis sliding table 3, a y-axis sliding table 4, a cross sliding table support 5, four servo motors 6, a speed reducer 7, a rotating motor 8, a blade 9 and a blade fixed support 10.

[0018] The cutting rotary mechanism support 1 is fixed on a platform supporting the whole knife sharpening mechanism, the rotary arms are installed on the inner sides of the cutting rotary mechanism fixed support and can rotate around an axis through bearings. The cross slide fixed support is installed between the two rotary arms to connect and fix the two rotary arms. The servo motor and the speed reducer 7 are fixed through the connecting shaft and the rotary arm and are fixed using the connecting shaft and the rotary arm 2. When the servo motor rotates, it can drive the rotary arm to rotate, realizing automatic angle changing cutting and automatic knife sharpening and adjusting functions. The two linear slides, the x-axis slide 3 and the y-axis slide 4, are installed in a cross shape, one linear slide is installed on the slide of the other linear slide, and the whole is installed on the cross slide support 5, realizing the horizontal and vertical movement of the slide.

[0019] When the debugging personnel debug the application, the point position during knife sharpening is determined, the position of the motor during knife sharpening is set in advance, and the knife sharpening position is set in the control system. When the cutting rotary mechanism blade needs to be sharpened, the blade is rotated to the upper knife sharpening position by the rotary motor, and the translation sharpening frame is translated to the knife sharpening position by the lead screw mechanism.

[0020] During normal cutting operation, the rotary motor 8 rotates to the vertical downward position, the blade 9 is fixed on the slide of the linear slide through the blade fixed support 10 and realizes horizontal and vertical cutting movement together with the slide; when knife sharpening operation is needed, the rotary motor rotates to the vertical upward position, the translation sharpening frame translates to the knife sharpening position, the rotary arm rotates to press the blade against the knife sharpening stone, and the pre-pressure is applied by the spring, and the knife sharpening operation is realized through horizontal and vertical movement.

[0021] As shown in Figure 3 , the translation sharpening frame mainly comprises a servo motor 11, a lead screw mechanism 12, a sliding block 13, a base 14, a fixed frame body 15, a spring 16, a guide column 17, a knife sharpening stone 18, a water outlet pipe 19, a water inlet hose interface 20 and a water outlet 21.

[0022] The fixed frame body 15 is installed on the base 14, the servo motor installed at the end point of the lead screw mechanism drives the lead screw mechanism 12 and the sliding block 13 to translate, and the grinding surface of the knife sharpening stone 18 is installed at a certain angle and matches the grinding angle of the blade. During normal cutting operation, the translation sharpening frame translates to the avoiding position and does not affect the cutting operation, when knife sharpening operation is needed, the translation sharpening frame translates to the knife sharpening position, the rotary arm rotates to press the blade against the knife sharpening stone, the pre-pressure is applied by the spring, and the knife sharpening operation is realized through horizontal and vertical movement. The water outlet pipe 19 is provided above the knife sharpening stone 18, and the water outlet 21 on the water outlet pipe 19 performs water cooling during the knife sharpening operation.

[0023] As shown in Figure 4 , the process of the automatic knife sharpening operation of the above-mentioned automatic device is as follows:

[0024] After a period of cutting operation, the cutting tool blade becomes blunt, which affects the quality of the section, and needs to be ground. First, the x-axis sliding table 3 and the y-axis sliding table 4 are adjusted to the middle position, and the rotating arm 2 is rotated to the grinding position. The rotating motor 8 rotates the cutting blade 9 to be vertically upward, and then the translation grinding frame is translated to the grinding position by using the lead screw mechanism 12. By deforming the compression spring 16, a certain pre-pressure is applied, which is convenient for grinding.

[0025] The cutting device sets corresponding parameters in the control system according to the grinding action. The corresponding servo motors of the x-axis sliding table 3 and the y-axis sliding table 4 make reciprocating motion, the longitudinal motor moves downward, and the water outlet pipe 19 is cooled by water injection through the water inlet hose interface 20 during the grinding action. When the longitudinal motion servo motor reaches the set position and the horizontal motion servo motor reaches the original position, the horizontal motion servo motor stops until the grinding action is completed.

[0026] When the longitudinal motion servo motor reaches the original position, the x-axis sliding table and the y-axis sliding table device proceed step by step according to the calculated grinding position. After a single grinding action is completed, a signal is sent to the control system, and the control system controls the cutting mechanism to repeat the grinding action. At the same time, the number of grinding is recorded. When the number of grinding is equal to the calculated number of grinding, it means that the grinding is completed. The water inlet valve is closed, the translation grinding frame is translated to the initial position, and the x-axis sliding table 3, the y-axis sliding table 4 and the rotating arm 2 are adjusted to the initial position.

[0027] As shown in Figure 5 , the cutting tool uses the pre-pressure of the spring on the grinding stone to set the corresponding grinding action times. The reciprocating motion of the horizontal motion servo motor and the longitudinal motion servo motor realizes the grinding of the blade length and angle. The water outlet pipe cools and flushes the cutting tool. When double blades need to be ground, the cutting tool can be installed by turning over, and the above-mentioned action is repeated to realize the grinding of double blades.

[0028] The present application can set the number of grinding actions and adjust the grinding pre-pressure, realize the grinding of different blade lengths and angles, and realize the grinding of double blades, which meets different grinding needs.

[0029] Finally, it should be noted that the above-mentioned near is one specific embodiment of the present application. Obviously, the present application is not limited to the above-mentioned embodiment, and many variations can also be made. All variations that can be directly derived or inferred by those skilled in the art from the disclosed content of the present application should be considered as the protection scope of the present application.
