Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, specifically a standardized feeding device for a cutting mesh. Background Technology

[0002] Eyebrow trimmers and shaving razors are tools that achieve smooth and safe grooming through their mesh structure and the cutting edge of the blade. The core component of these tools is the protective mesh (net) welded to the outside of the blade. The mesh is symmetrically welded to both sides of the blade. To accommodate the installation angle of the blade and the overall structural design requirements of the tool, the mesh must be folded before welding to the blade. This ensures that the mesh forms a preset bending angle that matches the sidewall of the blade, guaranteeing a good fit and providing a qualified semi-finished product for subsequent welding processes. The mesh needs to be cut and bent before it can be fed into the welding process. The mesh usually needs to be bent multiple times to ensure that the dimensions of the bent product are within the preset range. Therefore, a device is needed that can continuously cut and bend the mesh multiple times, automatically separate waste material after bending, and automatically feed the finished product. This reduces process costs and labor intensity, and meets the needs of large-scale and standardized production.

[0003] Chinese patent CN217750006U discloses a wire mesh feeding mechanism for an automatic wire mesh welding machine for eyebrow trimmer blades. The mechanism includes a Z-shaped bracket fixed to the outside of the welding machine platform. A motor is fixedly embedded in the Z-shaped bracket, and a C-shaped flip plate is fixedly connected to the motor's output shaft. One end of the C-shaped flip plate is fixedly connected to a fixed outer plate. Inside the fixed outer plate, two symmetrical movable inner plates slide, each with a straight tube movably inserted. The bottom end of each straight tube is connected to a vacuum suction cup, and an L-shaped movable rod is movably sleeved on the outside of each straight tube. The two L-shaped movable rods slide inside the same fixed outer plate. An electric push rod is fixed to one side of the bottom of the C-shaped flip plate. An adjustment mechanism connects the two L-shaped movable rods to the fixed outer plate. A positioning mechanism connects the straight tubes to the L-shaped movable rods. The vacuum suction cups can adhere to the smooth surface of the wire mesh and then vacuum-adhere it. The positioning mechanism includes a rod movably inserted into the L-shaped movable rod, with a pull block fixed to one end of the rod.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent cannot perform multiple bending and cutting operations in one step, resulting in low processing efficiency of the cutting mesh and the inability to achieve rapid and continuous feeding of the cutting mesh.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention adopts a step-by-step bending design with a combination of inclined plane fixing blocks and right angle fixing blocks through a multi-step bending mechanism. The blade mesh is first bent at a certain angle, and then bent to ninety degrees a second time. Compared with the method of bending ninety degrees at one time, it effectively avoids the deformation and warping problems caused by excessive instantaneous force on the blade mesh, and greatly improves the forming accuracy and appearance quality of the blade mesh. At the same time, the bending component is equipped with an elastic sliding frame and auxiliary support components. When the upper mold moves down, it can adaptively fit the material strip, ensuring the positioning stability of the blade mesh during the bending process. Moreover, the cutting component is linked with the bending mechanism. After bending, the cutting column can directly cooperate with the rectangular protrusion of the limiting frame to complete the cutting, realizing the integrated operation of bending and cutting, eliminating the intermediate transfer link, and significantly improving the processing efficiency of the blade mesh.

[0020] 2. The intermittent conveying mechanism enables precise and stable intermittent feeding of the material belt. The unwinding assembly is driven by a servo motor to unwind the reel, and the unwinding speed can be flexibly adjusted. It works in conjunction with the guide frame to achieve initial guidance of the material belt. The feeding assembly uses a guide rod inserted into the positioning hole of the material belt and completes fixed-distance conveying through the third linear module, which effectively avoids the problems of deviation and slippage during the material belt conveying process. After conveying, the L-shaped pressure block can quickly fix the material belt to prevent the material belt from shifting in subsequent bending and cutting processes, thus ensuring the feeding accuracy.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] The present invention will be further described below with reference to embodiments.

[0044] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0045] Example 1: In some examples, please refer to Figures 1-18 A standardized cutting tool feeding device includes a frame 1, and further includes an intermittent conveying mechanism 2, a multi-step bending mechanism 3, and a feeding mechanism 4. The intermittent conveying mechanism 2 for intermittently conveying and fixing the cutting tool is installed on one side of the frame 1. The multi-step bending mechanism 3 for bending and cutting the conveyed cutting tool is installed on one side of the frame 1. The feeding mechanism 4 for multi-station feeding of the cutting tool is installed in the middle of the frame 1.

[0046] The multi-step bending mechanism 3 includes a bending component and a cutting and transferring component. The bending component is mounted on the frame 1, and the cutting and transferring component is mounted on the frame 1. The bending component includes a lower die component and an upper die component. The lower die component is mounted on the frame 1, and the upper die component is mounted on the lower die component. The cutting and transferring component includes a cutting component and a receiving component. The cutting component is mounted on the upper die component, and the receiving component is mounted on the frame 1.

[0047] The material strip of the cutting mesh is conveyed to the bending component position of the multi-step bending mechanism 3 through the intermittent conveying mechanism 2. After being bent multiple times by the bending component, it is cut by the cutting and transferring component. The feeding mechanism 4 conveys the cut cutting mesh to the standard position, waiting for subsequent processing.

[0048] like Figure 1 , Figure 10 , Figure 11 , Figure 13 , Figure 14 , Figure 15 As shown, the lower mold assembly includes: a support frame 31, a lower support plate 32, a sliding frame 33, a first spring 34, a lower inclined surface fixing block 35, and a lower right angle fixing block 36. The support frame 31 is fixedly installed on the machine frame 1. The lower support plate 32 is fixedly installed on the middle side of the support frame 31. Two sliding frames 33 are slidably connected to the lower support plate 32. A plurality of first springs 34 are fixedly installed inside the lower support plate 32. The end of the first spring 34 away from the lower support plate 32 is fixedly connected to the sliding frame 33. Two lower inclined surface fixing blocks 35 are fixedly installed on the lower support plate 32. The two lower inclined surface fixing blocks 35 are located inside the left sliding frame 33. Two lower right angle fixing blocks 36 are fixedly installed on the lower support plate 32. The two lower right angle fixing blocks 36 are located inside the right sliding frame 33.

[0049] like Figure 15 As shown, the lower mold assembly further includes an auxiliary support assembly, which is mounted on the lower support plate 32. The auxiliary support assembly includes a sliding column 37 and a second spring 38. The sliding columns 37 are slidably connected to the left and right sides of the lower support plate 32. The second spring 38 is fixedly mounted on the sliding column 37. The end of the second spring 38 away from the sliding column 37 is in close contact with the lower support plate 32. The sliding column 37 is used to assist in supporting the cutting wire strip, and the second spring 38 provides elastic support for the sliding column 37.

[0050] like Figure 10 , Figure 11 , Figure 12 , Figure 16As shown, the upper mold assembly includes: a first cylinder 39, an upper support plate 310, an upper inclined surface fixing block 311, an upper right angle fixing block 312, and positioning posts 313. The first cylinder 39 is fixedly installed on the upper side of the support frame 31. One end of the upper support plate 310 is slidably connected to the upper side of the lower support plate 32, and the other end of the upper support plate 310 is fixedly connected to the output end of the first cylinder 39. Two upper inclined surface fixing blocks 311 are fixedly installed on the lower side of the upper support plate 310, two upper right angle fixing blocks 312 are fixedly installed on the lower side of the upper support plate 310, and multiple positioning posts 313 are fixedly installed on the lower side of the upper support plate 310. The upper inclined surface fixing blocks 311 and the lower inclined surface fixing blocks 35 correspond one-to-one, and the upper right angle fixing blocks 312 and the lower right angle fixing blocks 36 correspond one-to-one.

[0051] The material strip of the cutting mesh is conveyed to the position between the lower support plate 32 and the upper support plate 310 through the intermittent conveying mechanism 2. The output end of the first cylinder 39 of the upper mold assembly extends, causing the upper support plate 310, the upper inclined surface fixing block 311, the upper right angle fixing block 312 and the positioning post 313 to move downward. The upper support plate 310 moves downward, causing the sliding frame 33 of the lower mold assembly to move downward. The first spring 34 undergoes elastic deformation and is compressed. The downward movement of the sliding frame 33 causes the lower inclined surface fixing block 35 and the lower right angle fixing block 36 to protrude and contact the material strip.

[0052] The upper inclined surface fixing block 311 moves downward, cooperating with the lower inclined surface fixing block 35 of the lower mold assembly to bend the blade mesh on the material strip once, bending it at a certain angle. The angle of the first bend is usually between 30 and 60 degrees. Then the material strip continues to move intermittently, and the upper right-angle fixing block 312 cooperates with the lower right-angle fixing block 36 of the lower mold assembly to bend the blade mesh a second time after the first bend, so that the blade mesh is bent to 90 degrees. Through multiple bends, the blade mesh is bent to a 90-degree state, which is conducive to quickly performing multiple consecutive bends to bend the blade mesh to 90 degrees. Compared with the method of bending 90 degrees at one time, it effectively avoids problems such as deformation and warping of the blade mesh due to excessive instantaneous force, and greatly improves the forming accuracy and appearance quality of the blade mesh.

[0053] like Figure 12 , Figure 13 As shown, the cutting assembly includes: cutting posts 314 and limiting frame 315. Two cutting posts 314 are fixedly installed on the upper support plate 310, and the limiting frame 315 is fixedly installed on the lower support plate 32. Multiple rectangular protrusions are fixedly installed on the front and rear sides of the limiting frame 315 to assist the cutting blade mesh.

[0054] After being bent to 90 degrees, the cutting mesh continues to move, reaching a position between the cutting column 314 and the limiting frame 315. The upper support plate 310 moves downward, causing the cutting column 314 to move towards the cutting mesh position. In conjunction with the multiple rectangular protrusions on the limiting frame 315, the bent cutting mesh is cut off. This facilitates rapid and continuous bending and cutting of the cutting mesh, enabling rapid forming and quick unloading, resulting in high processing efficiency. The cutting component and bending mechanism are linked, allowing the cutting column 314 to directly cooperate with the rectangular protrusions of the limiting frame 315 to complete the cutting after bending. This achieves integrated bending and cutting operations, eliminating intermediate transfer links and significantly improving the processing efficiency of the cutting mesh.

[0055] Example 2: In some embodiments, such as Figures 1-18 As shown, in a preferred embodiment of the present invention, the receiving assembly includes: a first linear module 316, a second linear module 317, and a vertical frame 318. The first linear module 316 is fixedly mounted on the frame 1, the second linear module 317 is fixedly mounted on the output end of the first linear module 316, and the two vertical frames 318 are fixedly mounted on the output end of the second linear module 317. A V-shaped slot 319 is provided on the upper side of the vertical frame 318, and a plurality of first through holes 320 are provided on the V-shaped slot 319. The first through holes 320 are connected to an external device that generates negative pressure. The negative pressure of the first through holes 320 adsorbs the blade mesh, making it less likely to slip off the V-shaped slot 319 of the vertical frame 318.

[0056] While the blade mesh, bent at a 90-degree angle, is cutting, the output end of the first linear module 316 of the receiving assembly moves, causing the second linear module 317 to move. The output end of the second linear module 317 moves, causing the two vertical frames 318 to move directly below the blade mesh. After being cut, the blade mesh falls into the V-shaped slot 319 of the vertical frame 318, where it is attracted by the multiple first through holes 320 of the V-shaped slot 319. The output end of the first linear module 316 moves, causing the second linear module 317 to move. The output end of the second linear module 317 moves, causing the vertical frame 318 and the blade mesh to move to the position of the feeding mechanism 4, waiting for feeding.

[0057] The intermittent conveying mechanism 2 includes an unwinding assembly and a feeding assembly. The unwinding assembly is installed on one side of the frame 1, and the feeding assembly is installed on the support frame 31.

[0058] like Figure 2 , Figure 3 , Figure 4 As shown, the unwinding assembly includes a servo motor 21, a reel 22, and a guide frame 23. The servo motor 21 is fixedly mounted on the frame 1, the reel 22 is fixedly mounted on the output shaft of the servo motor 21, and the guide frame 23 is fixedly mounted on the frame 1.

[0059] The strip of the blade mesh is placed on the reel 22 of the unwinding assembly, and the material is slowly unwound by rotating the servo motor 21. The strip is then conveyed to the feeding assembly position through the guide frame 23.

[0060] like Figure 8 , Figure 9 As shown, the feeding assembly includes: a guide frame 24, a third linear module 25, a fourth linear module 26, guide rods 27, a second cylinder 28, and an L-shaped pressure block 29. The guide frame 24 is fixedly installed on one side of the support frame 31, and multiple strip slots 210 are provided on the guide frame 24. The third linear module 25 is fixedly installed on one side of the support frame 31, the fourth linear module 26 is fixedly installed at the output end of the third linear module 25, and two guide rods 27 are fixedly installed at the output end of the fourth linear module 26. The end of the guide rod 27 away from the output end of the fourth linear module 26 is located in the strip slot 210. The second cylinder 28 is fixedly installed on the support frame 31, and the L-shaped pressure block 29 is fixedly installed at the output end of the second cylinder 28.

[0061] The material strip is conveyed through the guide frame 23 to the guide frame 24 of the feeding assembly. The output end of the fourth linear module 26 moves downward, driving the guide rod 27 to move downward. The guide rod 27 is inserted into the positioning hole of the material strip. The output end of the third linear module 25 moves, driving the fourth linear module 26 and the guide rod 27 to move. The movement of the guide rod 27 pushes the material strip to move a preset distance. Then, the output end of the second cylinder 28 extends, driving the L-shaped pressure block 29 to move towards the material strip, fixing the material strip and avoiding the problems of deviation and slippage during the material strip conveying process. Moreover, after conveying, the L-shaped pressure block 29 can quickly fix the material strip, preventing the material strip from shifting in subsequent bending and cutting processes, and ensuring feeding accuracy.

[0062] Example 3: In some embodiments, such as Figures 1-18 As shown, in a preferred embodiment of the present invention, the feeding mechanism 4 includes: a fifth linear module 41, a first slide cylinder 42, a second slide cylinder 43, a moving frame 44, a rotary worktable 45, a turntable 46, and a tooling 47. The fifth linear module 41 is fixedly mounted on the frame 1. The first slide cylinder 42 is fixedly mounted on the output end of the fifth linear module 41. The second slide cylinder 43 is fixedly mounted on the output end of the first slide cylinder 42. The two moving frames 44 are fixedly mounted on the second... At the output end of the slide cylinder 43, a V-shaped protrusion 48 is fixedly installed on the lower side of the moving frame 44. The V-shaped protrusion 48 has multiple second through holes 49. The second through holes 49 are connected to an external device that generates negative pressure. The negative pressure of the second through holes 49 adsorbs the blade net, making it difficult for it to slip off the V-shaped protrusion 48 of the moving frame 44. The rotary worktable 45 is fixedly installed on the frame 1. The turntable 46 is fixedly installed at the output end of the rotary worktable 45. Multiple tooling fixtures 47 are fixedly installed on the turntable 46.

[0063] like Figure 5 , Figure 6 , Figure 7 , Figure 17 , Figure 18 As shown, the output end of the second linear module 317 moves, causing the vertical frame 318 and the cutting mesh to move to the position of the feeding mechanism 4. The output end of the second slide cylinder 43 of the feeding mechanism 4 moves downward, causing the moving frame 44 to move downward. The moving frame 44 moves to the position of the cutting mesh in the V-shaped slot 319. The multiple second through holes 49 on the V-shaped protrusion 48 attract the cutting mesh, making it difficult for it to slip off the V-shaped protrusion 48 of the moving frame 44. The output end of the second slide cylinder 43 moves upward, causing the moving frame 44 and the cutting mesh to move upward. The output end of the fifth linear module 41 moves, causing the first slide cylinder 42 and the second slide cylinder to move upward. 43. The moving frame 44 and the knife net move. The output end of the second slide cylinder 43 moves downward, driving the moving frame 44 and the knife net to move downward to the tooling position 47. The knife net is placed on the tooling 47. The output end of the rotating worktable 45 rotates, driving the turntable 46 to rotate. The tooling 47 for the next hole moves to the position below the knife net. The output end of the first slide cylinder 42 moves, driving the second slide cylinder 43 and the knife net to move directly above the tooling 47. The output end of the second slide cylinder 43 moves downward, driving the moving frame 44 and the knife net to move downward and place the knife net on the tooling 47, realizing rapid and continuous feeding of the two knife nets.
