Description

Technical Field

[0001] This utility model belongs to the field of reflective aluminum coil cutting and processing technology, specifically relating to a reflective aluminum coil stable slitting device. Background Technology

[0002] Reflective aluminum can be used in a wide range of applications, including signs, nameplates, vehicle license plates, vehicle body reflectivity, and architectural decoration. It mainly involves coating the aluminum base with reflective adhesive and protective adhesive layers, and requires multiple processes such as unwinding, applying adhesive layers, bonding metal reflective layers, drying, applying reflective adhesive layers, drying, applying protective adhesive layers, drying, and rewinding.

[0003] In the specific production and processing process, in order to meet production needs, it is usually necessary to cut and rewind larger aluminum coils to meet different processing requirements. In specific operation, when the existing aluminum coil cutting device cuts long aluminum coils, after the aluminum coil is unwound, the unwound aluminum sheet is conveyed to the bottom of the cutting blade by the conveyor roller group. The cutting blade is driven by the drive component to press down and cut. Then, the rewinding device rewinds the cut aluminum sheet to achieve the purpose of rewinding.

[0004] During the unwinding, conveying, and rewinding processes, the aluminum sheet is wound onto the unwinding roller and the rewinding roller respectively, and is also conveyed by the conveying roller group in between. It is in a certain state of tension and tautness. The cutting blade moves downward under the drive component to press down and cut. The aluminum sheet is separated into two segments with the cutting blade as the boundary. At the moment of cutting, the aluminum sheet on both sides of the cutting line will loosen and bounce up momentarily. In severe cases, it can easily cut the staff, which is not safe. It can also easily cause the wound aluminum sheet on the unwinding roller and the rewinding roller to loosen, affecting the unwinding and rewinding effect, and thus reducing the slitting efficiency.

[0005] Therefore, it is necessary to develop a stable slitting device for reflective aluminum rolls in order to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a reflective aluminum roll stabilizing slitting device that presses the aluminum sheets on both sides of the slitting blade during slitting to prevent instantaneous loosening and bounce during cutting, ensuring safety during slitting, preventing loosening during unwinding and rewinding, and improving work efficiency.

[0007] The purpose of this utility model is achieved as follows: a reflective aluminum coil stabilizing slitting device includes an unwinding mechanism, an infeed drive roller group is provided on one side of the unwinding mechanism, a stabilizing slitting mechanism is provided on the other side of the infeed drive roller group, an outfeed drive roller group is provided on the other side of the stabilizing slitting mechanism, and a winding mechanism is provided on the other side of the outfeed drive roller group.

[0008] The stable slitting mechanism includes a linear drive assembly fixedly mounted above the aluminum sheet to be slitted. A horizontal support plate is fixedly connected to the bottom output end of the linear drive assembly. A slitting blade is positioned at the middle of the bottom end of the horizontal support plate. Pressure plates are respectively mounted on both sides of the slitting blade. A guide rod is fixedly mounted at the top of the pressure plate. The top of the guide rod passes through the horizontal support plate and can slide up and down to connect with the horizontal support plate. A compression spring is sleeved on the portion of the guide rod located between the pressure plate and the horizontal support plate. When the compression spring is in its natural state, the bottom end of the pressure plate is lower than the bottom end of the slitting blade. A cutting support plate is positioned below the pressure plate. A cutting space is formed between the pressure plate and the cutting support plate, allowing the aluminum sheet to be slitted to pass through. A cutting groove is provided on the cutting support plate at the position corresponding to the slitting blade to accommodate the slitting blade.

[0009] Furthermore, the unwinding mechanism includes an unwinding roller and a drive motor assembly for driving the unwinding roller to rotate and unwind.

[0010] Furthermore, the winding mechanism includes a winding roller and a drive motor assembly for driving the winding roller to rotate and wind up.

[0011] Furthermore, a tensioning roller is also provided between the unwinding mechanism and the feed drive roller group.

[0012] Furthermore, the linear drive assembly is a cylinder assembly or a hydraulic cylinder assembly.

[0013] Furthermore, the horizontal support plate is embedded with a guide cylinder with openings at the top and bottom, and the guide rod can slide up and down to connect the guide cylinder through a sliding block assembly. A limit plate is fixedly provided at the top of the guide rod, and the width of the limit plate is greater than the outer diameter of the guide cylinder.

[0014] Furthermore, the width of the slitting blade is set to be adapted to or greater than the width of the aluminum sheet to be slitted.

[0015] The beneficial effects of this utility model are as follows: By setting pressure plates on both sides of the slitting blade, when the slitting blade is driven downward by the linear drive assembly to cut, the pressure plates press down synchronously, pressing the aluminum sheets on both sides of the slitting blade's cutting point into tight contact with the cutting support plate. This clamps the aluminum sheets on both sides of the cut, providing a buffer against the loosening that occurs when the aluminum sheets change from taut to broken during cutting, preventing the aluminum sheets on both sides of the cut from loosening and bouncing, thus increasing safety. It also ensures the effectiveness of unwinding and rewinding, preventing loosening during unwinding and rewinding, and making the slitting process smoother. The process is more stable and reliable. By placing the clamping plates on both sides of the slitting blade and setting the bottom of the clamping plates lower than the bottom of the slitting blade, the linear drive assembly moves the clamping plates downwards along with the slitting blade while it drives the blade to cut. This achieves both clamping and cutting with only one drive assembly, allowing the clamping plates to contact the aluminum sheet before the blade. The aluminum sheet can be clamped before cutting, and the blade continues to cut after clamping. This makes operation convenient, labor-saving, and more efficient. In summary, this invention has the advantages of being stable and reliable, highly safe, convenient and labor-saving, and effectively improving work efficiency. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2As shown, a reflective aluminum coil stabilizing and slitting device includes an unwinding mechanism 1, an infeed drive roller group 2, a stabilizing and slitting mechanism 3, an outfeed drive roller group 4, and a winding mechanism 5 mounted on a frame. The infeed drive roller group 2 is located on one side of the unwinding mechanism 1, the stabilizing and slitting mechanism 3 is located on the other side of the infeed drive roller group 2, the outfeed drive roller group 4 is located on the other side of the stabilizing and slitting mechanism 3, and the winding mechanism 5 is located on the other side of the outfeed drive roller group 4. Preferably, a tension roller 6 is also provided between the unwinding mechanism 1 and the infeed drive roller group 2. The aluminum sheet is unwound... After unwinding, the material is wound around the tension roller 6 and conveyed to the stabilizing slitting mechanism via the feed drive roller group 2. After being conveyed by the discharge drive roller group, it is wound onto the winding mechanism 5. Preferably, the unwinding mechanism 1 includes an unwinding roller and a drive motor assembly for driving the unwinding roller to rotate and unwind, and the winding mechanism 5 includes a winding roller and a drive motor assembly for driving the winding roller to rotate and rewind. It should be noted that the unwinding roller, winding roller, and drive motor assembly are all prior art and common knowledge to those skilled in the art. Therefore, they are not specifically limited here.

[0022] The stabilizing slitting mechanism 3 includes a linear drive assembly 31 fixedly mounted above the aluminum sheet to be slitted. Preferably, the linear drive assembly 31 can be a cylinder assembly or a hydraulic cylinder assembly. A horizontal support plate 32 is fixedly connected to the bottom output end of the linear drive assembly 31. A slitting blade 33 is provided at the middle position of the bottom end of the horizontal support plate 32. Preferably, the width of the slitting blade 33 is adapted to or greater than the width of the aluminum sheet to be slitted, so as to facilitate complete slitting of the aluminum sheet. A clamping plate 34 is provided on both sides of the slitting blade 33. A guide rod 35 is fixedly mounted on the top end of the clamping plate 34, and the top end of the guide rod 35 passes through the horizontal support plate 32. The plate 32 is slidably connected to the horizontal support plate 32. A compression spring 36 is sleeved on the part of the guide rod 35 located between the pressure plate 34 and the horizontal support plate 32. The top and bottom ends of the compression spring 36 are respectively fixedly connected to the bottom end of the horizontal support plate 32 and the top end of the pressure plate 34. When the compression spring 36 is in its natural state, the bottom end of the pressure plate 34 is lower than the bottom end of the slitting blade 33. A cutting support plate 37 is provided below the pressure plate 34. A cutting space 38 is formed between the pressure plate 34 and the cutting support plate 37, which allows the aluminum sheet to be slitted to pass through. A cutting groove 39 is provided on the cutting support plate 37 at the position corresponding to the slitting blade 33, which can accommodate the slitting blade 33.

[0023] Preferably, the sliding connection structure between the guide rod 35 and the horizontal support plate 32 can be as follows: the horizontal support plate 32 is embedded with a guide cylinder 310 with openings at the top and bottom respectively; the guide rod 35 can slide up and down to connect with the guide cylinder 310 through a sliding groove slider assembly; a limiting plate 311 is fixedly provided at the top of the guide rod 35; the width of the limiting plate 311 is greater than the outer diameter of the guide cylinder 310; the setting of the limiting plate can prevent the guide rod from slipping out of the guide cylinder, making it safer and more reliable to use.

[0024] The system also includes a controller and a drive power supply. The controller and drive power supply can be electrically connected to the unwinding mechanism 1, tension roller 6, feed drive roller group 2, linear drive assembly 31, discharge drive roller group 4 and winding mechanism 5 via power lines or other means. It should be noted that the controller, drive power supply, unwinding mechanism 1, tension roller 6, feed drive roller group 2, linear drive assembly 31, discharge drive roller group 4 and winding mechanism 5 and their specific circuit connection structures are all existing technologies and are common knowledge to those skilled in the art. They can be implemented in various ways, so no specific limitations are made here.

[0025] In a specific implementation of this utility model, the aluminum sheet is unwound by the unwinding mechanism 1, and the unwound aluminum sheet is wound around the tension roller 6 and then conveyed to the stabilizing slitting mechanism 3 via the infeed drive roller group 2. After being conveyed by the discharge drive roller group 4, it is wound onto the winding mechanism 5. When the aluminum sheet wound on the winding mechanism 5 reaches the slitting length, the conveying and winding are stopped, and the linear drive assembly 31 is activated, which drives the horizontal support plate 32, the slitting blade 33 and the pressing plate 34 set on the horizontal support plate 32 to move downward. When the pressing plate 34 abuts against the aluminum sheet to be cut and presses the aluminum sheet onto the cutting support plate 37, the horizontal support plate 32 continues to press down, the compression spring 36 begins to be compressed, and the guide rod 35 begins to slide up and down between the horizontal support plate 32. The horizontal support plate 32 and the slitting blade 33 continue to move downward until the slitting blade... The aluminum sheet is completely cut by the cutting blade 33, with the bottom end of the blade entering the cutting groove 39. After cutting, the horizontal support plate 32 is moved upward by the linear drive assembly 31. During the upward movement, the horizontal support plate 32 drives the cutting blade 33 to move upward first. In this process, the horizontal support plate 32 gradually reduces the downward pressure on the compression spring 36, and the compression spring 36 gradually returns to its original position. After the compression spring 36 has fully returned to its original position, the clamping plate 34 begins to move upward with the horizontal support plate 32 until the clamping plate 34 is completely separated from the aluminum sheet, thus completing one cutting operation. Repeating the above process can complete multiple cutting operations on the aluminum coil. By clamping and fixing the aluminum sheet on both sides of the cutting blade 33 with the clamping plate 34, the loosening and bouncing of the aluminum sheet on both sides caused by the cutting moment can be effectively avoided, resulting in higher safety, higher cutting efficiency, and better results.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
