Description

Technical Field

[0001] The utility model relates to the technical field of knife sharpening devices, in particular to an automatic knife sharpening machine. Background Art

[0002] Knives are widely used in people's lives. From star-rated hotels to people's daily lives, knives are indispensable. However, the more difficult thing is that there is no good knife sharpening method. Traditional knife sharpening can only be done by experienced masters purely by hand. The steps are cumbersome and time-consuming. Therefore, although the knife sharpening industry has been passed down from ancient times to the present, due to the advancement of science and technology, this industry has been declining. Now the knives people use are blunt and can only be scratched a few times on the whetstone. If there is no better solution, the only option is to replace the knife. A knife made of good material is usually more expensive due to the cumbersome production process. The existing knife sharpening machine only uses a simple grinding wheel to grind the blade as a whole.

The pressing device presses the tool, the mold-taking and profiling device positions the curvature of the blade, and the guide device moves along the positioning curvature of the mold-taking and profiling device, thereby causing the grinding device to grind along the curvature of the blade, completing the tool sharpening process, thereby increasing the tool's service life and improving the sharpening efficiency.

When double-sided grinding of tools with different curvatures is performed, positioning requires multiple operation steps and repeated adjustments, which reduces the efficiency and accuracy of the grinding.

[0006] Second, the existing grinding wheel can only be fed in a fixed direction and angle, and the angle of the grinding wheel cannot be adjusted according to different tools, which reduces the scope of use.

[0007] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0058] A positioning magnet located above the stepped top groove 27 is fixedly connected to the side wall of the side plate 25 , and the removal template 7 is positioned during the removal of the mold by the positioning magnet.

[0059] The take-out template 7 and the backing template 6 are arranged in an up-and-down staggered manner, and the front side of the take-out template 7 and the back side of the backing template 6 are in the same plane.

[0060] The contour adjustment seat includes a first hand-cranked slide 2 fixedly connected to the working platform 1 , and a push plate 4 is vertically fixedly connected to the movable end of the first hand-cranked slide 2 , and the front end of the push plate 4 is against the supporting template 6 and the taking template 7 .

[0072] The take-out template 7 and the backing template 6 are arranged in an up-and-down staggered manner, and the front side of the take-out template 7 and the back side of the backing template 6 are in the same plane.

[0073] This solution also discloses another method of use, namely, using the removal plate 7 alone to complete the mold removal and backing work. After the mold removal is completed, the removal plate 7 moves down along the side plate 25 to the backing plate 6 to perform work. When the tool 8 is grinding the other side, the tool 8 is turned over, and the backing plate 6 moves up to the removal position to perform work. After completion, it moves down to the backing plate 6 to perform work.

[0074] The structures of the first slide rail slide 12, the second slide rail slide 14, the first hand-cranked slide 2, the second hand-cranked slide 3 and the horizontal quick clamp 9 are all common on the market. Since the structure is not an innovation of this solution, it will not be described in detail here.

[0075] The working principle of this device is:

[0076] During use, the template 6 is moved to the bottom of the bottom groove 26, the template 7 is moved into the stepped top groove 27, and the template 7 is adsorbed and positioned by the adsorption magnet 28; the tool 8 is placed on the pad so that the blade of the tool 8 faces one side of the grinding wheel 22, and then the first hand-cranked slide 2 is shaken. The first hand-cranked slide 2 uses the push plate 4 to synchronously push the center position of the template 6 and the template 7 to move, so as to achieve the top bending of the template 6 and the template 7 and form an arc, adjust the precise arc matching state of the template 7 and the tool 8, and then lock it. Then, shake the second hand-cranked slide 3 so that the platform plate 48 is close to the template 7, leaving space for grinding feed during grinding, and then use a horizontal quick clamp to press the tool 8. The same arc matching is used when grinding the other side of the tool 8. Finally, the template 7 is moved down to the bottom of the stepped top groove 27. Adjust the angle of the grinding wheel 22 and lock it, then slide the slide bar 15 to adjust the grinding width of the grinding wheel and the tool 8 so that the suction piece 16 is against the template 6, lock the slide bar 15, and drive the grinding wheel 22 to move horizontally and vertically along the bending direction of the template 6 under the action of the first slide rail slide 12, the second slide rail slide 14 and the turntable 11. The turntable 11 rotates circumferentially and performs linkage work to achieve rapid grinding of the blade by the grinding wheel 22. When the tool 8 is turned over to grind the other side, the template 7 is moved up and the locked first arc is matched. After completion, the template 7 is moved down. Other operations are the same as the first time, which is convenient and fast.

[0077] Another solution: When the support plate 6 and the removal plate 7 share a common plate, the removal plate 7 is moved into the stepped top groove 27 and the removal plate 7 is attracted and positioned using a positioning magnet; the tool 8 is placed on the pad so that the blade of the tool 8 faces one side of the grinding wheel, and then the first hand-cranked slide 2 is shaken. The first hand-cranked slide 2 uses the push plate 4 to move the center position of the removal plate 7 synchronously to bend the removal plate 7 and form an arc. The arc matching state of the removal plate 7 and the tool 8 is adjusted. After adjustment, it is locked. The same arc matching is used for grinding the other side of the tool 8. Then the second manual slide 3 is shaken so that the platform plate 48 is close to the removal plate, leaving space for grinding feed during grinding. The tool is pressed with the horizontal clamp 9 and the removal plate 7 is moved down to the bottom groove 26; the removal plate 7 is converted to the function of the support plate 6, and then the grinding angle of the tool 8 is selected and locked in position. Then the slide bar 15 is slided so that the suction part 16 is against the support plate 6. The sliding slide bar 15 is adjusted to position the grinding width of the grinding wheel and then locked. The first and second slides 12 and 14, along with the turntable 11, work in tandem to achieve the grinding wheel 22. Guided by the suction element 16, it moves horizontally and vertically along the curved direction of the backing plate 6, and rotates circumferentially, enabling the grinding wheel to rapidly grind the blade. When the tool 8 is flipped over to grind the other side, the template 7 is moved up to the workstation, and the first arc matching is locked. After the arc matching is completed, the template 7 is moved down to the backing plate 6 workstation. Other operations are the same as the first time. Convenient and fast;

[0078] The grinding wheel 22 can be raised and lowered vertically by the lifting screw 19, adjusting the feed rate during grinding. The swinging mounting base 20 allows for 0-90° swing adjustment. The preset angle group positioning holes 23, 47, and locating pins 24 are used to secure the fixed angle. The first and second slide rails 12, 14, and turntable 11 are used to achieve horizontal and vertical sliding, as well as circumferential rotation. The grinding wheel 22 can grind different tools 8 to meet the required arc and angle precision, improving flexibility and ensuring grinding accuracy.

[0080] 1. Add enough cooling water, turn on the main power, and place the mold removal template in the mold removal position.

[0081] 2. Place the knife to be ground flat in the middle of the pad, shake the first hand-cranked slide, adjust the required blade curvature and template positioning, and after positioning, lock the position of the first hand-cranked slide.

[0082] 3. Shake the second hand-cranked slide, push the platform plate into place, leave space for grinding feed during grinding, and lock the position of the second hand-cranked slide.

[0083] 4. Press the knife onto the pad with a horizontal quick clamp.

[0084] 5. Take the template and move it down to the template-relying position, the function is converted, and the template-taking function becomes the template-relying function.

[0085] 6. Adjust the grinding angle of the grinding wheel head, position it, and lock it according to the function of the kitchen knife.

[0086] 7. Attach the suction part to the template, push the grinding assembly, adjust the required positioning so that the width of the grinding blade is synchronized with the width of the grinding surface of the grinding wheel, and tighten the locking angle adjustment handle bolt.

[0087] 8. Adjust the distance between the two position sensors according to the length of different tools and lock them.

[0088] 9. Turn on the water cooling, the motor drives the synchronous belt to rotate, the synchronous belt drives the grinding assembly to move, turn on the speed regulating motor, and adjust the grinding speed of the grinding wheel.

[0089] 10. Adjust the lifting screw to adjust the feed of the grinding wheel blade and start grinding.

[0090] 11. After the first side is ground, stop the power supply of the grinding wheel, water pump, and motor on the synchronous belt, open the horizontal quick clamp, turn the knife over, and prepare to grind the other side.
