Description

Technical Field

[0001] This invention belongs to the technical field of color-coated steel sheet slitting devices, specifically relating to a high-efficiency antibacterial color-coated steel sheet CNC machining and slitting device and a high-efficiency antibacterial color-coated steel sheet. Background Technology

[0002] High-efficiency antibacterial color-coated steel sheet is a special building material. This type of sheet is typically used in places with high hygiene requirements, such as hospitals, food processing plants, and laboratories. High-efficiency antibacterial color-coated steel sheet generally uses cold-rolled steel sheet or galvanized steel sheet as the base material, and coats one or more layers of antibacterial coatings on the surface of the steel sheet. These coatings may contain metal ions such as silver ions, zinc ions, and copper ions, or contain organic antibacterial agents, which can inhibit the growth of bacteria, mold, and viruses. After production, high-efficiency antibacterial color-coated steel sheet needs to be cut into the required size for easy transportation and installation later.

[0003] In existing technologies, when cutting color-coated steel sheets, the sheets are typically moved by a conveyor belt and then cut by a cutting device. The cutting device usually applies pressure to hold the cutting blade against the surface of the color-coated steel sheet to cut it. However, as the color-coated steel sheet moves with the conveyor belt, the cutting device briefly holds the surface of the sheet, causing the sheet to stop. This results in a brief bend in the subsequent sheets, which may cause the cut sheets to exceed the predetermined length, thus affecting the cutting accuracy.

[0004] A Chinese patent document with publication number CN117943608A discloses a CNC slitting device and method for antistatic color-coated steel sheets. This method addresses the aforementioned problem by setting the support plate and the color-coated steel sheet to move at the same speed. When the color-coated steel sheet is on the surface of the support plate, a telescopic rod drives a moving plate to move, causing the moving plate to press against the surface of the color-coated steel sheet. A second supporting plate also presses against the surface of the color-coated steel sheet. The rotation of rollers straightens the color-coated steel sheet, which is then cut by a cutting blade. The simultaneous movement of the cutting device and the color-coated steel sheet solves this problem. However, the synchronous movement of the support plate and the moving plate means that the cutting is completed during the movement, making the cutting process susceptible to the influence of the speed difference between the support plate and the moving plate. Any slight speed difference or time delay can lead to cutting position deviation or damage to the sheet surface. Furthermore, the cutting blade generates significant local stress on the color-coated steel sheet, especially when the sheet is thin, which can easily lead to local deformation or damage.

[0005] Therefore, this invention proposes a high-efficiency antibacterial color-coated steel sheet CNC machining and slitting device and a high-efficiency antibacterial color-coated steel sheet, which solves the problem that deformation or damage is easy to occur when cutting steel sheets using synchronous movement in the prior art. The device adopts a design of slitting and positioning components in conjunction with a support and limiting base to provide three-dimensional support for the cutting position to avoid deformation of the cutting area, and to minimize the adverse effects of the cutting action on the color-coated steel sheet during the slitting process.

[0035] To make the objectives, technical solutions, and advantages of the present invention clearer and more complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1, please refer to Figures 1 to 15This invention provides a technical solution: a high-efficiency antibacterial color-coated steel sheet CNC machining and slitting device, comprising a CNC machining and slitting device body 1, a material feeding component 11 on one side of the CNC machining and slitting device body 1, a material unloading component 12 on the other side of the CNC machining and slitting device body 1, a support and limiting base structure 2 above the middle of the CNC machining and slitting device body 1, and a slitting and positioning component 3 below the middle of the CNC machining and slitting device body 1. The support and limiting base structure 2 includes a fixed seat 21, a support and lifting seat 22, and a lifting cylinder 23. The slitting and positioning component 3 includes a lifting frame 31, a slitting blade holder 32, and a slitting and positioning frame 33. The fixed seat 21 is fixedly installed in the inner middle of the CNC machining and slitting device body 1, and the support and lifting seat 22 is snapped into place. Inside the fixed base 21, the lifting cylinder 23 is fixedly installed at the bottom of the main body 1 of the CNC machining and cutting device. The output end of the lifting cylinder 23 is fixedly connected to the lower surface of the supporting lifting base 22. A color-coated plate auxiliary fixing frame 1 24 is provided above the lifting cylinder 23 near the side of the feeding assembly 11, and a color-coated plate auxiliary fixing frame 25 is provided above the lifting cylinder 23 near the side of the unloading assembly 12. An image sensor 26 is fixedly installed in the middle of the lower surface of the color-coated plate auxiliary fixing frame 25. In this embodiment, the feeding assembly 11 is used to feed and deliver antibacterial color-coated plates, and the unloading assembly 12 is used to feed and unload the cut antibacterial color-coated plates. The output speeds of the feeding assembly 11 and the unloading assembly 12 are the same. When the antibacterial color-coated plates are moving normally... The lifting seat 22 is flush with the fixed seat 21, the feeding assembly 11, and the unloading assembly 12 to ensure the normal movement of the antibacterial color-coated sheet. At this time, the second auxiliary fixing frame 25 and the first auxiliary fixing frame 24 of the color-coated sheet are above the fixed seat 21 and do not contact the surface of the antibacterial color-coated sheet. The image sensor 26 is mainly used to monitor the movement status of one side of the antibacterial color-coated sheet. The movement distance of one side of the antibacterial color-coated sheet can be obtained by multiplying the movement time of one side of the antibacterial color-coated sheet detected by the image sensor 26 by the output speed of the feeding assembly 11. Adding half of the fixed length of the fixed seat 21 gives the retention distance. The sum of the movement distance and the retention distance is the cutting length of the antibacterial color-coated sheet. The lifting cylinder 23 is controlled by the CNC device to lift intermittently. Whenever the antibacterial color-coated sheet moves After a fixed time period, the lifting cylinder 23 lifts, causing the support lifting seat 22 to support the antibacterial color-coated plate away from the plane of the conveying component 11 and the unloading component 12 and stop moving. At this time, the color-coated plate auxiliary fixing frame 1 24 and the color-coated plate auxiliary fixing frame 25 work together to clamp the two sides of the antibacterial color-coated plate. The lifting frame 31 presses down to cut, thus obtaining the antibacterial color-coated plate body 4 of a fixed length. Then, the lifting frame 31 lifts and the lifting cylinder 23 retracts, causing the support lifting seat 22 to carry the cut antibacterial color-coated plate back to the transport plane to continue conveying. The cut antibacterial color-coated plate body 4 is output and unloaded through the unloading component 12. Moreover, the cutting length of the antibacterial color-coated plate can be changed by controlling the lifting interval of the lifting cylinder 23. The operation is simple and the cutting accuracy is high.

[0037] Example 2, please refer to Figures 1 to 15Based on Embodiment 1, this embodiment further proposes that the auxiliary fixing bracket 24 and the auxiliary fixing bracket 25 of the color-coated steel sheet have the same structure. Spring support columns 252 are fixedly installed at both ends of the lower surface of the auxiliary fixing bracket 255. The lower ends of the spring support columns 252 are fixedly connected to the upper surface of the fixing base 21. Gear racks 251 are symmetrically fixedly installed on the side surface of the auxiliary fixing bracket 255. A stabilizing trigger seat 253 is fixedly installed on one side of the lower surface of the auxiliary fixing bracket 255. An upper fixing plate 254 is hinged to the other side of the lower surface of the auxiliary fixing bracket 25 for color-coated steel sheets. Rack 221 is symmetrically fixed to both sides of the support lifting seat 22. A positioning and cutting groove 222 is provided in the middle of the upper surface of the support lifting seat 22. A sliding groove adapted to rack 221 and rack 251 is provided on the inner side of the fixing seat 21. A gear 211 is rotatably mounted in the middle of the sliding groove. The sides of the gear 211 mesh with the side surfaces of rack 251 and rack 221 respectively. A movable clamping plate 223 is symmetrically and movably installed inside the upper surface of the 22. Cylindrical balls are movably installed on the upper surface of the movable clamping plate 223. A stabilizing spring rod 2231 is movably installed below the movable clamping plate 223. The lower end of the stabilizing spring rod 2231 is movably connected to the inner wall of the support lifting seat 22. A slitting area support plate 224 is symmetrically arranged on both sides of the positioning slitting groove 222. The slitting area support plate 224 is movably installed inside the support lifting seat 22. A return spring 2 is fixedly installed at the bottom of the slitting area support plate 224. 241, the lower end of the return spring 2241 is fixedly connected to the inner wall of the support lifting seat 22, and a cutting area support plate 224 is fixedly installed on the side surface of the cutting area support plate 224 near the positioning cutting groove 222. A cutting area compensation support seat 2242 is provided on both ends of the cutting area support plate 224. A pressing start Z-shaped plate 2243 is symmetrically arranged at both ends of the cutting area support plate 224. The pressing start Z-shaped plate 2243 is rotatably installed on the side wall of the support lifting seat 22. A cutting limit groove 225 adapted to the position of the pressing start Z-shaped plate 2243 is provided on the upper surface of the support lifting seat 22.In this embodiment, the auxiliary fixing frame 24 and the auxiliary fixing frame 25 of the color-coated plate have the same structure. After the support lifting seat 22 is lifted, the two sides of the antibacterial color-coated plate are clamped and fixed to keep the antibacterial color-coated plate stable during the cutting process. This embodiment takes the auxiliary fixing frame 25 of the color-coated plate as an example to specifically explain the clamping principle. First, when the support lifting seat 22 is aligned with the fixing seat 21, the material conveying component 11, and the material unloading component 12, the auxiliary fixing frame 25 of the color-coated plate does not contact the upper surface of the antibacterial color-coated plate under the elastic support of the spring support column 252, which facilitates the movement of the antibacterial color-coated plate. At this time, the movable clamping plate 223 above the support lifting seat 22 is kept stable and balanced under the elastic support of the stabilizing spring rod 2231. The cylindrical balls distributed on the movable clamping plate 223 can reduce the friction between the antibacterial color-coated plate and the support lifting seat 22, making the movement of the antibacterial color-coated plate smoother. Once the lifting cylinder 23 works, it causes the support lifting seat 22 to be lifted, thus supporting the antibacterial color-coated plate. As the support lifting seat 22 rises, rack 221 moves upwards. At this time, rack 251, in conjunction with gear 211 and rack 221, is pulled downwards. Simultaneously, the auxiliary fixing frame 25 for the color-coated sheet presses down, compressing the spring support column 252. The stabilizing contact seat 253 presses down, actuating one side of the movable clamping plate 223, causing the side of the movable clamping plate near the positioning and cutting groove 222 to tilt upwards. This pre-fixes the cutting area of ​​the antibacterial color-coated sheet. Simultaneously, the tilting of one side of the movable clamping plate causes the upper part of the antibacterial color-coated sheet to be squeezed and clamped by rack 251. This pre-clamping before cutting ensures the sheet material is stable, improving cutting accuracy and cut quality. Furthermore, the dynamic adjustment mechanism formed by the movable clamping plate 223 and the auxiliary fixing frame 25 can adaptively adjust according to different sheet thicknesses, making it suitable for various specifications of antibacterial color-coated sheets and enhancing the equipment's versatility and flexibility.

[0038] Example 3, please refer to Figures 1 to 15Based on Embodiment 2, this embodiment further proposes that the lifting frame 31 is movably mounted above the fixed base 21 via a limiting sleeve. A pressing cylinder 311 is fixedly mounted on the top of the main body 1 of the CNC machining slitting device. The output end of the pressing cylinder 311 is fixedly connected to the upper surface of the lifting frame 31. The slitting blade holder 32 is fixedly mounted in the middle of the lifting frame 31, and the position of the slitting blade holder 32 corresponds to the position of the positioning slitting groove 222. The slitting positioning frame 33 is fixedly mounted on both sides of the lower surface of the lifting frame 31, and the position of the slitting positioning frame 33 corresponds to the position of the color-coated plate auxiliary fixing frame 24. The slitting positioning frame 33 is close to the slitting blade holder 32. One side surface is fixedly mounted with a compensation support 332 for the slitting cut. Both ends of the slitting positioning frame 33 are provided with limiting pins 331 that are compatible with the slitting limiting groove 225. An elastic protective frame 333 is movably installed inside the lower part of the slitting positioning frame 33. In this embodiment, after the antibacterial color-coated plate is lifted and pre-clamped, the pressing cylinder 311 drives the lifting frame 31 to press down. The slitting blade installed inside the slitting blade holder 32 cooperates with the positioning slitting groove 222 to directly slit the antibacterial color-coated plate. More importantly, during the pressing process of the lifting frame 31, the limiting pins 331 will engage with the slitting limiting groove 225 to play a slitting positioning role. Then... As the lifting frame 31 continues to press down, the limiting pin 331 presses one end of the extrusion-initiating Z-shaped plate 2243, causing the extrusion-initiating Z-shaped plate 2243 to flip. This causes the slitting area support plate 224 to be lifted and cooperate with the slitting positioning frame 33 to provide upper and lower support near the slitting cut of the antibacterial color-coated plate. This support can significantly reduce stress concentration around the cut, maintain the flatness of the cut, and prevent deformation of the cut during slitting, resisting slitting deformation. The lower compensating support seat 2242 and the upper compensating support seat 332 of the slitting cut adopt an arc-shaped curved opposing support clamp, which not only can it support the cut of the antibacterial color-coated plate during slitting but also... The system compensates for the large pressure generated by the cutting area, disperses the pressure, and prevents the coating near the cut from collapsing. It effectively reduces damage to the surface coating of the board during the cutting process. Especially for materials with high surface quality requirements, such as antibacterial color-coated boards, it can maintain their antibacterial properties and appearance integrity, and also prevent small displacements during cutting. Through the cooperation of the cutting area support plate 224 and the cutting positioning frame 33, the upper and lower parts near the cutting area can be evenly supported, making the cutting process more stable. The uniform force distribution can reduce the vibration and shaking that may occur during the cutting process, further improving the cutting quality and preventing errors in the cut.After slitting, the pressing cylinder 311 drives the lifting frame 31 to lift, causing the slitting blade holder 32 and the slitting positioning frame 33 to leave the pressure on the antibacterial color-coated plate. At this time, the slitting area support plate 224 and the extrusion starting Z-shaped plate 2243 are reset with the cooperation of the return spring 2241. Then, the lifting cylinder 23 drives the support lifting seat 22 to reset and maintain a level position with the fixed seat 21, the unloading assembly 12, and the conveying assembly 11. The color-coated plate auxiliary fixing frame 25 is reset with the cooperation of the rack 251, the rack 221, the gear 211, and the spring support column 252. At this time, the stabilizing touch seat 253 cancels the contact with the movable clamping plate 223. The movable clamping plate 223 is reset with the cooperation of the stabilizing spring rod 2231, so that the antibacterial color-coated plate continues to move and be conveyed.

[0039] Example 4, please refer to Figures 1 to 15 Based on Embodiment 3, this embodiment further proposes a high-efficiency antibacterial color-coated sheet, including an antibacterial color-coated sheet body 4, with storage grooves 41 evenly distributed on the surface of the antibacterial color-coated sheet body 4, and an antibacterial color coating 42 disposed above the storage grooves 41. In this embodiment, the storage grooves 41 on the surface of the storage grooves 41 to be coated can increase the adhesion area of ​​the antibacterial color coating 42, which can significantly increase the contact and interlocking between the antibacterial color coating 42 and the antibacterial color coating 42, thereby enhancing the adhesion of the coating and making the antibacterial color coating 42 more evenly distributed on the surface of the storage grooves 41, further improving the bonding performance, making the antibacterial color coating 42 less likely to fall off. After increasing the adhesion area, even if some areas are subjected to external impact or wear, it will not easily lead to large-area peeling. The stronger adhesion and better durability enable the antibacterial color coating 42 to maintain its function for a long time, reducing the frequency of maintenance and replacement, extending the service life of the product, and making the antibacterial color-coated sheet more efficient.

[0040] Example 5, please refer to Figures 1 to 15Based on Embodiment 4, this embodiment also proposes a slitting method for a high-efficiency antibacterial color-coated steel sheet CNC machining slitting device, including the following steps: Step 1, the entire antibacterial color-coated steel sheet is placed above the feeding assembly 11. With the cooperation of the feeding assembly 11 and the unloading assembly 12, the antibacterial color-coated steel sheet is conveyed between the support limiting base structure 2 and the slitting positioning assembly 3. After the antibacterial color-coated steel sheet has moved for a fixed period of time, the lifting cylinder 23 lifts, so that the support lifting seat 22 supports the antibacterial color-coated steel sheet away from the plane of the feeding assembly 11 and the unloading assembly 12 and no longer moves; Step 2, the support lifting seat... As rack 22 is lifted and moved upward, rack 251 is pulled downward by gear 211 and rack 221, causing auxiliary fixing bracket 25 of the color-coated plate to press down. The stabilizing contact seat 253 presses down and touches one side of the movable clamping plate 223, causing the side of the movable clamping plate 223 near the positioning and cutting groove 222 to tilt up, thus pre-fixing the cutting area of ​​the antibacterial color-coated plate. In step three, after the antibacterial color-coated plate is lifted and pre-clamped, the pressing cylinder 311 drives the lifting frame 31 to press down, and the limiting pin 331 presses one end of the extrusion starting Z-shaped plate 2243, causing the extrusion starting Z-shaped plate 2243 to flip. This causes the slitting area support plate 224 to be lifted and cooperate with the slitting positioning frame 33 to provide upper and lower support near the slitting cut of the antibacterial color-coated plate. The lower compensation support seat 2242 and the upper compensation support seat 332 of the slitting cut cooperate to compensate for the large pressure generated near the cut when the antibacterial color-coated plate is slitting. The slitting blade installed inside the slitting blade holder 32 cooperates with the positioning slitting groove 222 to directly slitting the antibacterial color-coated plate. Step four: After slitting is completed, the pressing cylinder 311 drives the lifting frame 31 to lift, so that the slitting blade holder 32 and the slitting positioning frame 33 are removed from the pressure on the antibacterial color-coated plate. At this time, the slitting zone support plate 224 and the extrusion start Z-shaped plate 2243 are reset with the cooperation of the reset spring 2241. Then, the lifting cylinder 23 drives the support lifting seat 22 to reset and maintain a level position with the fixed seat 21, the unloading assembly 12 and the conveying assembly 11. The color-coated plate auxiliary fixing frame 25 is reset with the cooperation of the rack 251, the rack 1 221, the gear 211 and the spring support column 252. At this time, the stabilizing touch seat 253 cancels the resistance to the movable clamping plate 223. The movable clamping plate 223 is reset with the cooperation of the stabilizing spring rod 2231, so that the antibacterial color-coated plate continues to move and be conveyed.
