Description

Technical Field

[0001] This utility model relates to the field of roll material processing equipment technology, and in particular to a roll material slitting device with high-precision slitting and dynamic compensation functions, which is suitable for precision slitting of flexible roll materials such as metal foil, polymer film, and composite materials. Background Technology

[0002] In industrial production, roll slitting is a common processing step, widely used in the processing of various materials such as paper, film, and metal strip. Existing roll slitting devices have some problems in actual operation. For example, the slitting blade is prone to positional shifts during long-term use, and existing devices often struggle to monitor and adjust the blade's position in real time. This leads to a decline in roll cutting quality, resulting in dimensional errors and uneven cuts. Therefore, a new type of roll slitting device is needed to solve these problems. Utility Model Content

[0003] In view of this, the present invention provides a roll material slitting device to solve the problem of difficulty in monitoring and adjusting the position of the slitting blade in the prior art, thereby improving the accuracy and quality of roll material slitting.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A roll material slitting device includes a support mechanism, a conveying mechanism, and a slitting mechanism. The support mechanism includes a horizontally arranged support plate with a plurality of perforated holes spaced apart along its width. Guide bushings are fixed to the inner walls of the perforated holes. The conveying mechanism includes conveying roller groups symmetrically arranged on both sides of the support plate along its length. The conveying roller groups include a driving conveying roller and a driven conveying roller arranged in parallel. The slitting mechanism includes a mounting bracket, a pneumatic gripper, and a slitting blade. The mounting bracket is fixed below the support plate. The pneumatic gripper is connected to the mounting bracket and holds the slitting blade. The blade body of the slitting blade penetrates through the guide bushing, and its cutting direction is orthogonal to the roll material conveying direction. The pneumatic gripper is equipped with an adjustment module. The tip of the slitting blade protrudes from the upper surface of the support plate. A permanent magnet is embedded inside the slitting blade. A magnetic field detection component is provided on the outer wall of the guide bushing.

[0006] The roll material slitting device involved in this solution has a crucial and unique technical feature: it can monitor and adjust the position of the slitting blade in real time, thereby effectively ensuring the cutting quality of the roll material.

[0007] Specifically, permanent magnets are carefully embedded inside the slitting blade, while a matching magnetic field detection component is installed on the outer wall of the guide bushing. Based on this innovative structural design, the magnetic field detection component, through the magnetic field effect generated by the permanent magnets, can continuously and accurately monitor the spatial position of the slitting blade in real time.

[0008] During the actual operation of a roll slitting device, many factors can cause the slitting blade to change position, such as blade wear caused by long-term high-frequency operation, or unavoidable vibrations during equipment operation, all of which may lead to blade misalignment. The magnetic field detection component can sensitively capture these positional changes and accurately determine whether the slitting blade has shifted or whether its position has changed due to wear.

[0009] Once the magnetic field detection component detects any deviation of the slitting blade's position from the preset state, it will quickly and accurately feed back the relevant information. At this point, the adjustment module equipped with the pneumatic gripper will play a crucial role. This adjustment module can quickly and precisely adjust the slitting blade's position according to the information fed back by the magnetic field detection component, ensuring that the slitting blade is always in the optimal working position.

[0010] Through the synergistic use of the above-mentioned technical means, this roll material slitting device can maintain a high slitting accuracy throughout the entire slitting process, effectively avoiding problems such as cutting size errors and uneven cuts caused by slitting blade position deviations, thereby comprehensively improving product quality and meeting the strict requirements of industrial production for high precision and high quality roll material slitting. Compared with existing technologies, it has significant progress and advantages.

[0011] Preferably, a movable fit clearance is formed between the guide bushing and the slitting blade body.

[0012] This clearance design allows the slitting blade to move flexibly within the guide bushing, effectively buffering the instantaneous impact caused by unevenness or material uniformity of the roll material during slitting. Compared to traditional tight-fitting structures, this movable clearance avoids excessive stress on the slitting blade due to rigid contact, significantly reducing the risk of blade damage and extending its service life. Simultaneously, this clearance also provides the slitting blade with a certain degree of self-adaptation during cutting, allowing it to better adapt to the minute deformations of the roll material, further improving slitting accuracy and quality, demonstrating innovation and practicality superior to existing technologies.

[0013] Preferably, the magnetic field detection component includes multiple Hall sensors evenly distributed circumferentially on the outer wall of the guide bushing, with the detection surface of each Hall sensor facing the magnetic field distribution area of ​​the permanent magnet.

[0014] Multiple circumferentially distributed Hall sensors can monitor the magnetic field changes of the permanent magnet in real time and comprehensively from different angles, thereby accurately obtaining the position information of the slitting blade. Compared with the monitoring method of a single sensor, this multi-sensor layout greatly improves the accuracy and reliability of monitoring, and can more sensitively capture minute positional changes of the slitting blade in various directions. Whether it is a horizontal offset of the slitting blade or a slight displacement in the vertical direction, it can be accurately detected. The design of each Hall sensor's detection surface facing the magnetic field distribution area of ​​the permanent magnet ensures that the sensor can receive the magnetic field signal to the maximum extent, effectively improving the detection sensitivity. This provides a solid data foundation for timely and accurate adjustment of the slitting blade position, demonstrating the advanced nature of this invention in slitting blade position monitoring technology.

[0015] Preferably, the outer wall of the guide bushing is covered with an electromagnetic shielding layer.

[0016] In complex industrial production environments, various electromagnetic interference sources exist, which may affect the accurate acquisition of slitting blade position information by the magnetic field detection component. The electromagnetic shielding layer effectively blocks external electromagnetic interference, ensuring that the magnetic field signal detected by the magnetic field detection component primarily originates from the permanent magnet inside the slitting blade, thereby improving the accuracy and stability of magnetic field detection. This design enables the roll material slitting device to operate reliably under different electromagnetic environments, reducing slitting blade position monitoring errors caused by electromagnetic interference, ensuring slitting accuracy and product quality, demonstrating the unique advantages of this invention in resisting electromagnetic interference, and enhancing the applicability and reliability of the device.

[0017] Preferably, the adjustment module includes a three-dimensional precision displacement platform and a pressure feedback unit. The three-dimensional precision displacement platform drives the slitting blade to perform spatial six-degree-of-freedom pose adjustment, and the pressure feedback unit monitors the clamping pressure in real time and generates a dynamic compensation signal.

[0018] The three-dimensional precision displacement platform can drive the slitting blade to perform six-degree-of-freedom spatial pose adjustment. This means that the slitting blade can achieve precise position and attitude adjustment in the X, Y, and Z linear directions, as well as rotational directions around these three axes. This all-round precise adjustment capability allows the slitting blade to quickly and accurately adapt to the slitting requirements of different roll materials. Whether it is fine-tuning the slitting position or precise control of the slitting angle, it can be easily achieved, greatly improving the flexibility and versatility of the slitting device. The pressure feedback unit monitors the clamping pressure in real time and generates dynamic compensation signals to ensure that the clamping force of the pneumatic gripper on the slitting blade is always in the optimal state. During the slitting process, as the slitting blade wears or the characteristics of the roll material change, the clamping pressure may need to be adjusted accordingly. The pressure feedback unit can detect these changes in time and automatically adjust the clamping pressure by generating dynamic compensation signals, ensuring the stability and reliability of the slitting blade during the cutting process, effectively avoiding slitting blade loosening or damage caused by improper clamping force, thereby improving slitting quality and efficiency, demonstrating the leading level of this utility model's adjustment module in terms of intelligence and precision control.

[0019] Preferably, the slitting blade includes a handle and a detachable blade head.

[0020] During the slitting process of rolled materials, the cutter head, as the part directly involved in cutting, inevitably wears down due to continuous friction and impact with the rolled material. The detachable cutter head design means that when the cutter head wears down, it is not necessary to replace the entire slitting blade; simply remove the worn cutter head and replace it with a new one to continue operation. This feature greatly reduces the cost of blade replacement and avoids the waste of resources and economic losses caused by discarding the entire slitting blade due to partial wear of the cutter head. Compared with traditional integrated slitting blades, this design can save companies significant tool procurement costs over long-term production, improve the utilization efficiency of production resources, and enhance the company's cost competitiveness in the market.

[0021] Preferably, the surface of the detachable cutter head is provided with a diamond-like carbon composite coating.

[0022] Diamond-like carbon composite coatings possess extremely high hardness, wear resistance, and chemical stability. During slitting, this coating effectively resists wear on the cutting head from the coiled material, reducing the wear rate of the cutting tool, extending its service life, and lowering production costs. Simultaneously, the coating's chemical stability prevents chemical reactions when the cutting head cuts certain special materials, ensuring slitting quality.

[0023] Preferably, the conveying mechanism further includes a plurality of guide rollers, which are disposed between the active conveying roller and the driven conveying roller.

[0024] The guide rollers precisely guide and correct the position and orientation of the roll material during transport. As the roll material is conveyed from the active conveyor roller to the driven conveyor roller, deviations and twisting may occur due to factors such as the roll material's weight and uneven tension distribution. The guide rollers, through contact with the roll material, apply appropriate force to keep it on the correct transport path, ensuring smooth and stable transport. Furthermore, the guide rollers can fine-tune the tension of the roll material, preventing stretching, deformation, or loosening caused by excessive or insufficient tension. This ensures the flatness and stability of the roll material during slitting, creating favorable conditions for improving slitting accuracy. This demonstrates the rationality and scientific nature of the conveying mechanism design in this invention, enhancing the overall performance of the roll material slitting device.

[0025] A smart production device includes a roll slitting device as described above.

[0026] The advantages of this utility model compared to the prior art are:

[0027] This utility model's roll slitting device enables real-time monitoring and timely adjustment of the slitting blade position, thereby effectively ensuring the cutting quality of the roll material. A permanent magnet is carefully embedded inside the slitting blade, and a matching magnetic field detection component is installed on the outer wall of the guide bushing. Based on this innovative structural design, the magnetic field detection component, utilizing the magnetic field effect generated by the permanent magnet, can continuously and accurately monitor the spatial position of the slitting blade in real time. During the actual operation of the roll slitting device, many factors may cause changes in the position of the slitting blade, such as blade wear caused by long-term high-frequency operation, or unavoidable vibrations during equipment operation, all of which may lead to blade misalignment. The magnetic field detection component can sensitively capture these positional changes, accurately judging whether the slitting blade has misaligned or its position has changed due to wear. Once the magnetic field detection component detects any abnormality in the slitting blade position deviating from the preset state, it will quickly and accurately feed back the relevant information. At this time, the adjustment module equipped with the pneumatic gripper plays a crucial role. This adjustment module can quickly and accurately adjust the position of the slitting blade based on the information fed back by the magnetic field detection component, ensuring that the slitting blade is always in the optimal working position. Throughout the entire slitting process, this roll slitting device maintains a high level of slitting accuracy, effectively avoiding problems such as cutting size errors and uneven cuts caused by slitting blade position deviations. This comprehensively improves product quality and meets the stringent requirements of industrial production for high precision and high quality roll slitting, demonstrating significant progress and advantages compared to existing technologies.

[0039] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0040] This embodiment provides a roll material slitting device, including a support mechanism 1, a conveying mechanism 2, and a slitting mechanism 3. The support mechanism 1 includes a horizontally arranged support plate 11, which has a plurality of perforated holes 111 spaced apart along its width direction, and guide bushings 112 are fixed to the inner walls of the perforated holes 111. The conveying mechanism 2 includes conveying roller groups 21 symmetrically arranged on both sides of the support plate 11 along its length direction, and the conveying roller groups 21 include parallelly arranged driving conveying rollers 211 and driven conveying rollers 212. The slitting mechanism 3 includes a mounting bracket. 31. Pneumatic gripper 32 and slitting blade 33. Mounting bracket 31 is fixed below the support plate 11. Pneumatic gripper 32 is connected to mounting bracket 31 and clamps slitting blade 33. The blade body of slitting blade 33 passes through guide bushing 112. Its cutting direction is orthogonal to the roll material conveying direction. Pneumatic gripper 32 is provided with adjustment module 321. The blade tip of slitting blade 33 protrudes from the upper surface of support plate 11. Permanent magnet 331 is embedded inside slitting blade 33. Magnetic field detection component 1121 is provided on the outer wall of guide bushing 112.

[0041] The roll material slitting device involved in this solution has a crucial and unique technical feature: it can achieve real-time monitoring and timely adjustment of the slitting blade 33 position, thereby effectively ensuring the cutting quality of the roll material.

[0042] Specifically, a permanent magnet 331 is carefully embedded inside the slitting blade 33, while a matching magnetic field detection component 1121 is provided on the outer wall of the guide bushing 112. Based on this innovative structural design, the magnetic field detection component 1121, by virtue of the magnetic field effect generated by the permanent magnet 331, can continuously and accurately monitor the spatial position of the slitting blade 33 in real time.

[0043] During the actual operation of the roll slitting device, many factors may cause the position of the slitting blade 33 to change, such as blade wear caused by long-term high-frequency operation, or unavoidable vibrations during equipment operation, all of which may cause the slitting blade 33 to shift. The magnetic field detection component 1121 can sensitively capture these positional change information and accurately judge whether the slitting blade 33 has shifted or changed position due to wear.

[0044] Once the magnetic field detection component 1121 detects any abnormality in the position of the slitting blade 33 that deviates from the preset state, it will quickly and accurately output the relevant information. At this time, the adjustment module 321 equipped with the pneumatic gripper 32 will play an important role. This adjustment module 321 can quickly and accurately adjust the position of the slitting blade 33 according to the information fed back by the magnetic field detection component 1121, ensuring that the slitting blade 33 is always in the optimal working position.

[0045] Through the coordinated use of the above-mentioned technical means, this roll material slitting device can maintain a high slitting accuracy throughout the entire slitting process, effectively avoiding problems such as cutting size errors and uneven cuts caused by the positional deviation of the slitting blade 33, thereby comprehensively improving product quality and meeting the strict requirements of industrial production for high precision and high quality roll material slitting. Compared with existing technologies, it has significant progress and advantages.

[0046] In this embodiment, a movable fit clearance is formed between the guide bushing 112 and the slitting blade 33.

[0047] This clearance design allows the slitting blade 33 to move flexibly within the guide bushing 112, effectively buffering the instantaneous impact force caused by unevenness or material inhomogeneity of the roll material during slitting. Compared to traditional tight-fitting structures, this movable clearance avoids excessive stress on the slitting blade 33 due to rigid contact, significantly reducing the risk of damage and extending its service life. Simultaneously, this clearance also provides the slitting blade 33 with a certain degree of adaptive space during cutting, enabling it to better adapt to the minute deformations of the roll material, further improving slitting accuracy and quality, demonstrating innovation and practicality superior to existing technologies.

[0048] In this embodiment, the magnetic field detection component 1121 includes a plurality of Hall sensors 11211 circumferentially distributed on the outer wall of the guide bushing 112, and the detection surface of each Hall sensor 11211 faces the magnetic field distribution area of ​​the permanent magnet 331.

[0049] Multiple circumferentially distributed Hall sensors 11211 can monitor the magnetic field changes of the permanent magnet 331 in real time and comprehensively from different angles, thereby accurately obtaining the position information of the slitting blade 33. Compared with the monitoring method of a single sensor, this multi-sensor layout greatly improves the accuracy and reliability of monitoring, and can more sensitively capture minute positional changes of the slitting blade 33 in various directions. Whether it is a horizontal offset of the slitting blade 33 or a slight displacement in the vertical direction, it can be accurately detected. The design of each Hall sensor 11211's detection surface facing the magnetic field distribution area of ​​the permanent magnet 331 ensures that the sensor can receive the magnetic field signal to the maximum extent, effectively improving the detection sensitivity. This provides a solid data foundation for timely and accurate adjustment of the slitting blade 33's position, demonstrating the advanced nature of this invention in slitting blade 33 position monitoring technology.

[0050] In this embodiment, the outer wall of the guide bushing 112 is covered with an electromagnetic shielding layer 1122.

[0051] In complex industrial production environments, various electromagnetic interference sources exist, which may affect the accurate acquisition of the slitting blade 33 position information by the magnetic field detection component 1121. The electromagnetic shielding layer 1122 effectively blocks external electromagnetic interference, ensuring that the magnetic field signal detected by the magnetic field detection component 1121 primarily originates from the permanent magnet 331 inside the slitting blade 33, thereby improving the accuracy and stability of magnetic field detection. This design enables the roll material slitting device to operate reliably under different electromagnetic environments, reducing the position monitoring error of the slitting blade 33 caused by electromagnetic interference, ensuring slitting accuracy and product quality, demonstrating the unique advantages of this invention in resisting electromagnetic interference, and improving the applicability and reliability of the device.

[0052] In this embodiment, the adjustment module 321 includes a three-dimensional precision displacement platform 3211 and a pressure feedback unit 3212. The three-dimensional precision displacement platform 3211 drives the slitting blade 33 to perform spatial six-degree-of-freedom pose adjustment, and the pressure feedback unit 3212 monitors the clamping pressure in real time and generates a dynamic compensation signal.

[0053] The three-dimensional precision displacement platform 3211 can drive the slitting blade 33 to perform six-degree-of-freedom spatial pose adjustment. This means that the slitting blade 33 can achieve precise position and attitude adjustment in the X, Y, and Z linear directions, as well as in the rotational directions around these three axes. This all-round precise adjustment capability allows the slitting blade 33 to quickly and accurately adapt to the slitting requirements of different roll materials. Whether it is fine-tuning the slitting position or precise control of the slitting angle, it can be easily achieved, greatly improving the flexibility and versatility of the slitting device. The pressure feedback unit 3212 monitors the clamping pressure in real time and generates a dynamic compensation signal, which can ensure that the clamping force of the pneumatic gripper 32 on the slitting blade 33 is always in the optimal state. During the slitting process, as the slitting blade 33 wears or the characteristics of the roll material change, the clamping pressure may need to be adjusted accordingly. The pressure feedback unit 3212 can sense these changes in a timely manner and automatically adjust the clamping pressure by generating a dynamic compensation signal to ensure the stability and reliability of the slitting blade 33 during the cutting process. This effectively avoids the slitting blade 33 from loosening or being damaged due to improper clamping force, thereby improving the slitting quality and efficiency. This demonstrates the leading level of the adjustment module 321 of this utility model in terms of intelligent and precise control.

[0054] In this embodiment, the slitting blade 33 includes a handle 332 and a detachable blade head 333.

[0055] During the slitting process of rolled materials, the cutter head, as the part directly involved in cutting, inevitably wears down due to continuous friction and impact with the rolled material. The detachable cutter head 333 design allows for easy replacement of the entire slitting cutter 33 when wear occurs; simply remove the worn cutter head and replace it with a new one to continue operation. This feature significantly reduces tool replacement costs and avoids the waste of resources and economic losses caused by discarding the entire slitting cutter 33 due to partial wear. Compared to traditional integrated slitting cutters, this design saves companies substantial tool procurement costs over long-term production, improves the utilization efficiency of production resources, and enhances the company's cost competitiveness in the market.

[0056] In this embodiment, the surface of the detachable cutter head 333 is provided with a diamond-like carbon composite coating with a thickness of 2-5 μm.

[0057] Diamond-like carbon composite coatings possess extremely high hardness, wear resistance, and chemical stability. A coating thickness of 2-5 μm ensures excellent adhesion between the coating and the cutter substrate while fully leveraging its protective function. During slitting, this coating effectively resists wear on the cutter from the coiled material, reducing the wear rate, extending the cutter's lifespan, and lowering production costs. Simultaneously, the coating's chemical stability prevents chemical reactions when cutting certain special materials, ensuring slitting quality.

[0058] In this embodiment, the conveying mechanism 2 further includes a plurality of guide rollers 22, which are disposed between the active conveying roller 211 and the driven conveying roller 212.

[0059] The guide roller 22 is designed to precisely guide and correct the position and orientation of the roll material during the conveying process. During the conveying of the roll material from the active conveyor roller 211 to the driven conveyor roller 212, deviations and twisting may occur due to factors such as the weight of the roll material itself and uneven tension distribution. The guide roller 22, through contact with the roll material, applies appropriate force to keep the roll material on the correct conveying path, ensuring smooth and stable conveying. Furthermore, the guide roller 22 can fine-tune the tension of the roll material, preventing deformation or loosening caused by excessive or insufficient tension. This ensures the flatness and stability of the material during the slitting process, creating favorable conditions for improving slitting accuracy. This demonstrates the rationality and scientific nature of the conveying design of this invention and enhances the overall performance of the roll material slitting device.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
