Description

Technical Field

[0001] The utility model relates to the technical field of cutting knives, in particular to an automatic grinding device for cutting knives. Background Art

[0002] A cutting knife is a tool used to cut various materials and is commonly found in kitchens, industrial production, construction sites and other fields.

[0003] A cutting blade is a tool component used to cut various materials. It is usually installed on mechanical equipment such as cutting machines, circular saws, milling machines, etc. Its main function is to cut metal, wood, plastic, stone and other materials through high-speed rotation or linear motion.

[0004] The design and material selection of the cutting blade depends on the specific application and the type of material to be cut.

[0005] Classification by shape:

[0006] Circular blades: commonly used in circular saws and rotary cutting equipment;

[0007] Straight blades: commonly used in shearing and straight cutting equipment;

[0008] Special-shaped blades: blades with special shapes customized according to specific needs.

[0009] Classification by material:

[0010] High-speed steel (HSS) blade: has good wear resistance and heat resistance, suitable for high-speed cutting;

[0011] Carbide blades: extremely high hardness, good wear resistance, suitable for cutting hard materials;

[0012] Ceramic blades: extremely hard, but brittle, suitable for cutting certain materials;

[0013] Diamond blade: mainly used for cutting extremely hard materials such as stone, concrete, etc.

[0014] At present, the most common cutting tool on the cutting table is the rotatable alloy circular blade. After continuous use, especially for cutting some metal pipes or plates, the cutting edge of the cutting knife is subject to relatively large wear and tear due to the required contact friction. If it is not polished regularly, it is easy to cause the cutting edge to become blunt, affecting the efficiency and quality of the cutting process. Utility Model Content

The lower end of the lifting plate 16 is respectively provided with a first motor 17 and a shaft seat 18, and the outer wall surface of the first motor 17 and the outer wall surface of the shaft seat 18 are fixedly assembled with the surface of the lifting plate 16 through a bracket. A first rotating shaft for driving is provided inside the first motor 17, and the end of the first rotating shaft extends outward through the interior of the first motor 17, and the outer end of the first rotating shaft is rotatably arranged with the interior of the shaft seat 18. A blade 19 made of round stainless steel is provided on the surface of the first rotating shaft, and the connection between the blade 19 and the first rotating shaft is fixedly assembled by screws.

[0035] The guide rail 12 is the fixed part of the guide rail pair and is usually installed on the equipment's foundation structure. Its main function is to provide a motion track for the slide and to bear the load transmitted by the slide. The material and design of the guide rail directly affect the accuracy and stability of the entire system.

[0036] The guide rail pair slide 13 is the moving part of the guide rail pair, and moves linearly along the track of the guide rail. Rolling bodies (such as balls, rollers) or sliding pads are usually installed inside the slide to reduce friction between the slide and the guide rail. The design and manufacturing accuracy of the slide directly affect the smoothness and accuracy of the movement.

[0037] It should be further explained that a foot 20 is provided at the lower end of the table top 10, and the upper end of the foot 20 is fixed to the surface of the table top 10 by screws. The foot 20 is symmetrically distributed along the lower end surface of the table top 10, which can ensure the stable support of the table top 10. At the same time, the strip hole 22 can be formed into a hollow blanking form.

[0038] It should be further explained that both sides of the support frame 11 are penetrated by a through hole 21, and the through hole 21 is a rectangular hole structure. A transparent plastic plate can be installed in the through hole 21 to facilitate peeping.

[0039] It should be further explained that a strip hole 22 is provided in the middle of the table top 10 and passes through the inside thereof. The width of the strip hole 22 is not less than the thickness of the blade 19, and the two are arranged in correspondence with each other up and down. The strip hole 22 can be penetrated by the blade 19 to avoid mutual damage caused by contact between the two.

[0040] It should be further explained that a second cylinder 30 is also provided at the lower end of the lifting plate 16, and the outer wall surface of the second cylinder 30 is fixedly assembled with the surface of the lifting plate 16 through a bracket, and a telescopic second piston rod is provided inside the second cylinder 30, and the end of the second piston rod extends outward through the interior of the second cylinder 30. There are two second cylinders 30 and they are symmetrically distributed along the blade 19. The second cylinder 30 can drive the grinding disc 32 to move back and forth.

[0041] It should be further explained that a second motor 31 is provided at the end of the second piston rod, and the outer wall surface of the second motor 31 is fixedly assembled with the end surface of the second piston rod by screws. A second rotating shaft for driving is provided inside the second motor 31, and the end of the second rotating shaft extends outward through the interior of the second motor 31. Both the first motor 17 and the second motor 31 are stepper models, and are powered by connecting a wire plug to the indoor 220V power socket.

[0042] It should be further explained that a grinding disc 32 is provided at the outer end of the second rotating shaft, and the grinding disc 32 is fastened to the end of the second rotating shaft by screws. The grinding disc 32 is made of diamond material, and the grinding disc 32 is a frustum structure, and the outer ring wall is matched with the cutting edge position of the blade 19. The grinding disc 32 can automatically contact the blade 19 through the control of the second cylinder 30 and the second motor 31 to realize the grinding of the cutting edge position of the blade 19, thereby ensuring the sharpness of the blade 19.

[0043] Working method: The guide rail sub-slide 13 slides on the guide rail sub-guide 12 to ensure the forward and backward movement of the blade 19. The first piston rod of the first cylinder 15 is extended and retracted to achieve the up and down movement of the blade 19. When the material passes through the table 10 and is placed under the blade 19, the material can be cut and separated. The strip hole 22 can prevent the blade 19 from direct contact with the table 10 and cause mutual loss.

[0044] After the blade 19 is used continuously, the second piston rod of the second cylinder 30 is extended, so that the second motor 31 can bring the grinding disc 32 into contact with the cutting edge of the blade 19, and the power of the second motor 31 is turned on, so that the rotating shaft of the second motor 31 can rotate with the blade 19, thereby realizing automatic grinding of the cutting edge of the blade 19 and ensuring the sharpness of the cutting edge of the blade 19.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
