Description

Technical Field

[0001] The invention relates to the technical field of knife and scissors processing, in particular to an automatic grinding device for knife and scissors cutting edges. Background Art

[0002] Kitchen knife and scissors are double-edged tools suitable for cutting meat, vegetables, chicken bones and other foods in the kitchen. The two blades are staggered and can be opened and closed. Kitchen knife and scissors can be used to process meat as scissors, and meat that requires laborious chopping such as chicken and duck. Not only are they more convenient to use, they can also prevent gravy from splashing everywhere and reduce the time of cleaning the chopping board.

[0003] During the production process of kitchen knives and scissors, grinding and polishing with grinding wheels of different shapes and grain sizes are required during the sharpening, grinding and polishing processes. When sharpening, the blade needs to be surface treated and trimmed; when sharpening, the blade needs to be ground and grinded to make it sharper and smoother; the final polishing process needs to improve the appearance quality and glossiness of the kitchen knives and scissors. The above processes all require grinding wheels for grinding. Regardless of the degree of grain size of the grinding wheel, in the above production process, the grinding wheel must be waxed during grinding. The traditional practice is to use manual waxing, which is usually done by workers sitting in front of the grinding wheel of the polishing machine during the production process, holding solid wax to make the surface of the grinding wheel adhere to the wax block.

[0004] The disadvantages of this approach are low efficiency and unsafety. When the grinding wheel of the polishing machine is running at high speed, it is very dangerous to use manual waxing, and the time and accuracy of waxing are difficult to control, and it is difficult to accurately control the quality standards of the products.

[0005] There are currently methods for automatic waxing, but generally liquid wax is used automatically. Although this method can solve the problem of automatic waxing in the production process, the quality of the product cannot be guaranteed when liquid wax is used in large-scale mechanized production processes, and the products produced are not as good as those using solid wax.

[0006] Based on the above situation, in view of the current needs of enterprises to mass-produce knife and scissors products, it is very necessary to invent an automatic solid waxing device for knife and scissors production to improve production efficiency, reduce safety risks in the production process, and ensure the uniform standard quality of products leaving the factory. Summary of the invention

[0007] In view of the deficiencies of the prior art, the present invention provides an automatic grinding device for knife and scissors blades, which overcomes the deficiencies of the prior art and effectively solves the problems of low production efficiency and high risk in the production process.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0024] 2. The automatic grinding device for knife and scissors blades of the present invention can coat the solid wax extruded by the extruder on the polishing wheel. When the polishing wheel rotates, the solid wax contacts the wax coating wheel. By rotating the screw to drive the wax coating wheel to move, the gap between the wax coating wheel and the polishing wheel can be controlled, thereby better ensuring that the solid wax is evenly coated on the polishing wheel, effectively ensuring the quality of the product.

[0025] 3.

[0036] In this embodiment, the wax storage cylinder 7 with solid wax can be placed in the waxing frame 4 and positioned using the positioning ring 18. One end of the wax storage cylinder 7 is stuck in the positioning ring 18. The cylinder 10 pushes the push head 11 to squeeze the movable handle 24 in the extrusion gun 5, and the extrusion plate 6 can be controlled to squeeze the wax storage cylinder 7 to compress it. The solid wax can be squeezed out through the extrusion head 9 on the wax outlet seat 8, thereby realizing automatic and precise waxing of the solid wax, with fast working efficiency and high safety factor.

[0037] Example 2, refer to Figure 6, an automatic grinding device for knife and scissors blades, a cylinder 10 is fixedly connected to the outer wall of the bottom of the waxing frame 4, and the piston rod of the cylinder 10 is fixedly connected to the push head 11, a connecting plate 12 is welded to the outer wall of the bottom of the waxing frame 4, and a screw rod 13 is screwed to the inner wall of the connecting plate 12, and a wax coating wheel 14 is rotatably connected to the outer wall of the screw rod 13, and a guide rod 15 slidably connected to the inner wall of the connecting plate 12 is welded to the outer wall of the plate frame of the wax coating wheel 14.

[0038] In this embodiment, the solid wax extruded by the extruder head 9 can be coated on the polishing wheel 35. During the rotation of the polishing wheel 35, the solid wax will contact the wax coating wheel 14. By rotating the screw 13 to drive the wax coating wheel 14 to move, the gap between the wax coating wheel 14 and the polishing wheel 35 can be controlled, thereby better ensuring that the solid wax is evenly coated on the polishing wheel 35, effectively ensuring the quality of the product.

[0040] In this embodiment, the side plate 20 can prevent the solid wax from transferring to the side of the polishing wheel 35. When the solid wax passes through the wax coating wheel 14 and the polishing wheel 35, a part of it remains on the polishing wheel 35 and the wax coating wheel 14, and the excess part falls on the lower slide plate 16. The solid wax leaked in the waxing frame 4 can be cleaned into the cleaning frame 17, which is convenient for cleaning. At the same time, the limit rod 19 is arranged on both sides of the top of the wax storage cylinder 7, which can limit the compression trajectory of the wax storage cylinder 7 and avoid the problem that the wax storage cylinder 7 is folded and cannot be squeezed out.

[0041] Reference Figures 4 to 6The extrusion gun 5 is provided with a mounting frame 21 fixedly connected to the outer wall of one end of the waxing frame 4, and the inner wall of the mounting frame 21 is slidably connected to a push rod 22, and the extrusion plate 6 is welded to the outer wall of one end of the push rod 22, and a fixed grip 23 is provided on the outer wall of the bottom of the mounting frame 21, and a movable grip 24 is rotatably connected to the outer wall of the fixed grip 23, and a push block 25 is rotatably connected to the outer wall of the top of the movable grip 24, and a first spring 26 is connected between the push block 25 and the mounting frame 21, and the top of the outer wall of one side of the mounting frame 21 is rotatable. A limiting plate 27 is connected, and a second spring 28 is connected between the limiting plate 27 and the mounting frame 21. When the cylinder 10 pushes the pushing head 11, the movable handle 24 can be controlled to be close to the fixed handle 23. At this time, the pushing block 25 is tilted, the first spring 26 is compressed, and the second spring 28 is stretched. The pushing block 25 will push the pushing rod 22 to move in the direction of the wax storage cylinder 7 to squeeze the wax storage cylinder 7. When the cylinder 10 stops pushing the head 11, the first spring 26 and the second spring 28 are reset, and the limiting plate 27 will clamp the pushing rod 22 to prevent it from moving.

[0042] Reference Figure 3 A solenoid valve 29 is fixedly connected to the outer wall of one side of the cross bar 3, and a compressed air branch pipe 30 is connected between the solenoid valve 29 and the cylinder 10. The top outer wall of the solenoid valve 29 is connected to a compressed air main pipe 31 with an air pump. The solenoid valve 29 can control the compressed air main pipe 31 to supply air to the compressed air branch pipe 30, thereby controlling the operation of the cylinder 10.

[0043] Reference Figure 7 A symmetrically distributed second column 32 is welded to the top outer wall of the base 1, and a support plate 33 is welded to the top outer wall of the second column 32. A servo motor 34 is installed on the top outer wall of the support plate 33. Polishing wheels 35 are installed at both ends of the output shaft of the servo motor 34. The side plates 20 are arranged on both sides of the polishing wheels 35. A bearing seat 36 is fixedly connected to the bottom outer wall of the support plate 33, and a rotating rod 37 is fixedly connected to the inner ring of the bearing inside the bearing seat 36. A sharpening wheel 38 is fixedly connected to the outer walls of both ends of the rotating rod 37. A pulley group 39 is installed between the output shaft of the servo motor 34 and the rotating rod 37, and a protective cover 40 is welded to the outer wall of the bottom outer wall of the support plate 33 outside the sharpening wheel 38. When the servo motor 34 is working, on the one hand, it will control the rotation of the two polishing wheels 35. Under the action of the pulley group 39, on the other hand, it can control the rotation of the sharpening wheel 38. The scissors body 44 can be sharpened by the sharpening wheel 38 first, and then polished by the polishing wheel 35.

[0044] Reference Figure 2An industrial robot 41 is arranged on one side of the base 1, and a clamp 42 is installed on the outer wall of one end of the industrial robot 41. A connecting frame 43 is arranged on one side of the industrial robot 41, and scissor bodies 44 are placed on the inner wall of the connecting frame 43 at equal distances. The industrial robot 41 can control the movement of the clamp 42, use the clamp 42 to clamp the scissor bodies 44 on the connecting frame 43, and then transfer the scissor bodies 44 to the sharpening wheel 38 and the polishing wheel 35 in turn for sharpening and polishing.

[0045] Working principle: When the servo motor 34 is working, it controls the two polishing wheels 35 to rotate on the one hand, and under the action of the pulley group 39, it can control the sharpening wheel 38 to rotate on the other hand. At this time, the clamp 42 is controlled to move by the industrial robot 41, and the clamp 42 is used to clamp the knife and scissors body 44 on the connecting frame 43, and then the knife and scissors body 44 is transferred to the sharpening wheel 38 and the polishing wheel 35 in turn for sharpening and polishing. When polishing, solid wax needs to be applied to the polishing wheel 35;

[0046] Under the action of the solenoid valve 29, the compressed air main pipe 31 is controlled to supply air to the compressed air branch pipe 30, thereby controlling the cylinder 10 to work. At this time, the cylinder 10 will push the push head 11 to control the movable handle 24 to approach the fixed handle 23. At this time, the push block 25 is tilted, the first spring 26 is compressed, and the second spring 28 is stretched. The push block 25 will push the push rod 22 to move in the direction of the wax storage cylinder 7 to squeeze the wax storage cylinder 7. The solid wax extruded by the extruder 9 can be coated on the polishing wheel 35. During the rotation of the polishing wheel 35, the solid wax will contact the wax coating wheel 14, and by rotating the screw 1 Driving the wax coating wheel 14 to move can control the gap between the wax coating wheel 14 and the polishing wheel 35, so as to better ensure that the solid wax is evenly coated on the polishing wheel 35. When the solid wax passes through the gap between the wax coating wheel 14 and the polishing wheel 35, a part of it remains on the polishing wheel 35 and the wax coating wheel 14, and the excess part falls on the lower slide plate 16, and the solid wax leaked in the waxing frame 4 can be cleaned into the cleaning frame 17. At the same time, the limit rods 19 are arranged on both sides of the top of the wax storage cylinder 7, which can limit the compression track of the wax storage cylinder 7 and avoid the problem that the wax storage cylinder 7 is folded and cannot be squeezed out.
