Abstract
Description
Technical Field
[0001] This invention relates to the field of aluminum production equipment technology, and in particular to a slitting machine with quick blade changing. Background Technology
[0002] A slitting machine, also known as a slitting line, longitudinal cutter, or strip slitting machine, is mainly used to uncoil, slit, and rewind metal coils into strips of the required width. It is an indispensable piece of equipment in metal material production. The slitting components of existing slitting machines mainly consist of a drive shaft and several disc shears mounted on the drive shaft. On some slitting machines, the distance between adjacent disc shears can be adjusted to meet the production needs of strips of different widths.
[0003] However, in actual use, since several disc shears are installed sequentially on the same drive shaft, if one disc shear suffers from chipping or nicking, it must be replaced to ensure the quality of the slitting strip. Replacing the disc shear requires stopping the entire machine, significantly impacting production efficiency. Even in existing slitting machines with two sets of cutting components as backups to ensure one set can continue slitting when replacing a disc shear, replacing it still requires removing all undamaged disc shears sequentially, unless the damaged disc shear is located at either end of the drive shaft. Finally, the intact disc shears must be reinstalled, which is time-consuming, labor-intensive, and increases the risk of accidental injury. Summary of the Invention
[0004] The purpose of this invention is to provide a slitting machine with rapid blade changing, which can quickly replace damaged disc shears without stopping the slitting operation or moving undamaged disc shears, thereby improving blade changing efficiency, reducing manual labor intensity, and improving safety.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:
[0006] A quick-change slitting machine includes a feeding mechanism, a slitting mechanism, and a winding mechanism arranged sequentially along the feeding direction. The slitting mechanism includes slitting frames arranged opposite each other on both sides of the feeding direction. A mounting rod is provided between the slitting frames, horizontally arranged perpendicular to the feeding direction. A plurality of cutting blade assemblies are arrayed along the length of the mounting rod. A drive assembly located on one side of the mounting rod and cooperating with the plurality of cutting blade assemblies is provided on the slitting frame. An auxiliary assembly is also provided on the slitting frame near the winding mechanism, and the cutting blade assemblies and the drive assembly are both located on the side of the auxiliary assembly away from the winding mechanism. A detection assembly is located between the auxiliary assembly and the cutting blade assemblies on the side of the auxiliary assembly away from the winding mechanism. A re-inspection assembly is provided on the side of the auxiliary assembly near the winding mechanism.
[0007] The cutting blade assembly includes a cutting blade ring coaxially arranged with the mounting rod. The outer wall of the cutting blade ring is circumferentially arrayed with a plurality of cutting blades arranged radially thereon. The end of each cutting blade away from the cutting blade ring is detachably mounted with a U-shaped clamp with an opening away from the cutting blade. A disc shear is rotatably mounted in the opening of the U-shaped clamp, and the axis of the disc shear is parallel to the axis of the cutting blade ring. During longitudinal cutting, one of the cutting blades is vertically downward, and the disc shear mounted at its lower end corresponds to and cooperates with the drive assembly.
[0008] The mounting rod is rotatably mounted on the slitting frame along its axial direction, and the mounting rod is provided with a number of limiting members arranged along its length direction to cooperate with the inner walls of the cutting rings one by one; under normal conditions, there is a clearance fit between the inner walls of the cutting rings and the outer wall of the mounting rod, and when the limiting members are working, there is an interference fit between the inner walls of the cutting rings and the outer wall of the mounting rod.
[0009] The drive assembly includes a drive shaft parallel to the mounting rod, with both ends of the drive shaft respectively positioned on corresponding slitting frames. A plurality of coaxial drive gears are arranged on the drive shaft along its length. A parallel crossbar is also provided on one side of the mounting rod, with both ends of the crossbar respectively mounted on corresponding slitting frames. A plurality of vertically downward-facing support plates are arranged on the crossbar along its length. A driven gear corresponding to each drive gear is rotatably mounted on the side wall near the lower end of each support plate. The axis of the driven gear is arranged along the length of the crossbar, and a transmission chain connects each drive gear and driven gear. Each driven gear is located on one side of the disc shear. A disk is mounted on the rotating shaft of the corresponding disc shear on the side of the U-shaped clamp near the corresponding driven gear. A first electromagnet cooperating with the disk is provided on the side of the driven gear near the disk. When the first electromagnet is energized, it attracts and fixes to the corresponding disk, and the driven gear drives the corresponding disc shear to rotate.
[0010] By adopting the above technical solution, the feeding mechanism releases the wide metal strip to be slit, and the driving component in the slitting mechanism drives several cutting components to slit the wide metal strip into narrow metal strips of appropriate width. The winding mechanism then winds up the narrow metal strips. During this process, the detection component checks for gaps on the slit surface of the narrow metal strips to determine if the working disc shear in the cutting component has any damage such as chipping or nicks. If the disc shear is damaged, it is replaced, and the auxiliary component temporarily takes over the slitting work to ensure the continuity of the slitting operation. The re-inspection component inspects the slit surface of the narrow metal strips cut by the auxiliary component. If both the detection component and the re-inspection component detect defects, it indicates that the disc shear is damaged. If only the re-inspection component detects defects, it indicates that the auxiliary component is damaged and needs to be replaced.
[0011] When the slitting mechanism performs slitting operations, one of the cutting rods in each cutting blade assembly points vertically downwards, and the disc shear at the lower end of the cutting rod is in the working state. The drive shaft in the drive assembly drives several driving gears to rotate in a positioning position. Under the transmission action of the transmission chain on the driving gears and driven gears, several driven gears are driven to rotate synchronously. Under the action of the first electromagnet on each driven gear being energized and attracted and fixed to the corresponding disk, each driven gear drives the corresponding disc shear to rotate, thereby making the working disc shears in several cutting blade assemblies rotate synchronously to slit and cut the wide metal strip.
[0012] When the detection component determines that the working disc shear in the cutter assembly is damaged by detecting the cutting surface of the narrow metal strip, it controls the corresponding limiting component of the cutter assembly containing the damaged disc shear to operate. This limiting component ensures an interference fit between the inner wall of the corresponding cutter ring and the outer wall of the mounting rod. Simultaneously, the first electromagnet on the corresponding driven gear is de-energized, releasing the fixing effect between the damaged disc shear and the corresponding driven gear. Then, the mounting rod rotates, driving the cutter assembly to rotate, moving the intact disc shear on the cutter assembly to the working position, quickly replacing the damaged disc shear. Damaged disc shears can be replaced all at once after the slitting operation is completed. If multiple disc shears in the cutter assembly fail consecutively, it indicates a problem with the slitting operation, and the slitting operation is paused for re-adjustment.
[0013] During the process of replacing the damaged disc shear by rotating the mounting rod, the limiting parts on other cutting blade assemblies do not work. The inner wall of the cutting blade ring in other cutting blade assemblies is in clearance fit with the outer wall of the mounting rod. Therefore, the other cutting blade assemblies will not rotate with the rotation of the mounting rod. The auxiliary components will also temporarily take over the longitudinal cutting work, so that the longitudinal cutting work does not need to be stopped during the replacement process, and the undamaged disc shear does not need to be moved. This improves the efficiency of blade replacement, reduces the intensity of manual labor, and improves safety.
[0014] Furthermore, the limiting component includes several limiting rods arranged in a circumferential array along the radial direction of the mounting rod. One end of each limiting rod, away from the axis of the mounting rod, is connected to an arc-shaped block that mates with the inner wall of the cutter ring. The side of the arc-shaped block closest to the inner wall of the cutter ring has several arc-shaped protrusions arranged in an array. The outer wall of the mounting rod has several limiting holes that mate with the limiting rods and clearance grooves that mate with the arc-shaped blocks in a circumferential array. The limiting holes and clearance grooves communicate with each other, and the clearance grooves are located at the end of the limiting holes away from the axis of the mounting rod. The limiting rods are slidably installed within the limiting holes and clearance grooves, and a tension spring and a cooperating second electromagnet are provided between the end of the limiting rod away from the arc-shaped block and the end of the limiting hole away from the clearance groove. Normally, when the second electromagnet is energized, the arc-shaped block and the arc-shaped protrusions are completely located within the clearance groove. When the second electromagnet is de-energized, under the action of the tension spring, the limiting rod slides away from the axis of the mounting rod, and the arc-shaped protrusions on the arc-shaped block abut tightly against the inner wall of the cutter ring.
[0015] By adopting the above technical solution, when the disc shear is performing normal longitudinal cutting, the second electromagnet is energized and attracted, the tension spring is compressed, and the arc-shaped block and arc-shaped protrusion are completely located in the clearance groove. The inner wall of the cutter ring and the outer wall of the mounting rod are fitted with a clearance, avoiding interference with the replacement of damaged disc shears. When it is necessary to drive the cutter assembly to rotate and replace the disc shear, the second electromagnet in the corresponding limiting component of the cutter assembly is de-energized. Under the action of the tension spring, the limiting rod is driven to slide away from the axis of the mounting rod, so that the arc-shaped protrusion on the arc-shaped block tightly abuts against the inner wall of the cutter ring, achieving an interference fit between the inner wall of the cutter ring and the outer wall of the mounting rod in the cutter assembly. This ensures that when the mounting rod rotates, it drives the cutter assembly to rotate synchronously to replace the disc shear. After replacement, the second electromagnet is energized to reset the arc-shaped block. The entire limiting component structure is simple, easy to operate, and facilitates control of the fit between the cutter ring and the mounting rod, enabling quick replacement of damaged disc shears without affecting the normal operation of other disc shears.
[0016] Furthermore, the inner wall of the U-shaped clamp near the cutter rod is provided with cotton felt, and the outer periphery of the disc shear abuts against the cotton felt; the cutter ring is provided with an annular oil storage cavity, the cutter rod is provided with an oil supply channel communicating with the annular oil storage cavity, the side wall of the U-shaped clamp located between the cotton felt and the cutter rod is provided with an oil supply hole communicating with the oil supply channel, and the oil supply hole penetrates the side wall of the U-shaped clamp near the cotton felt; the outer wall of the cutter ring is provided with an oil filling hole communicating with the annular oil storage cavity, and the end of the oil filling hole away from the annular oil storage cavity is provided with a plug.
[0017] By adopting the above technical solution, lubricating oil is introduced into the annular oil reservoir. The lubricating oil is delivered from the oil supply channel on the vertically downward cutting bar through the corresponding oil supply hole on the U-shaped clamp, and absorbed by the cotton felt inside the U-shaped clamp. The disc shear on the vertically downward cutting bar is in working condition. When the disc shear rotates to cut the metal strip, it continuously contacts the cotton felt. The cotton felt can coat the disc shear with lubricating oil, reducing wear and increasing its service life. On the other hand, it can wipe and clean the disc shear, preventing debris from adhering to it, which would not only affect the cutting effect on the metal strip but also its service life. When the lubricating oil in the annular oil reservoir is insufficient, the plug can be removed to open the oil filling hole and add lubricating oil to the annular oil reservoir, ensuring that the cotton felt absorbs sufficient lubricating oil to lubricate the disc shear. In addition, the oil in the annular oil reservoir always flows downward along the vertically downward oil supply channel. When the cutter assembly rotates to change the cutter, the lubricating oil in several oil supply channels will also flow back into the annular oil reservoir due to the change in the position of the oil supply channels, thus ensuring the lubrication effect of the disc shear in working condition.
[0018] Furthermore, the auxiliary component includes an auxiliary rod parallel to the mounting rod and vertically slidably mounted on the slitting frame at both ends. The auxiliary rod is provided with an auxiliary frame that slides along its length and is vertically arranged. An auxiliary blade is rotatably mounted at the lower end of the auxiliary frame, and the axis of the auxiliary blade is parallel to the axis of the disc shear.
[0019] By adopting the above technical solution, when the detection component continuously detects a notch in the cut surface after slitting, it indicates that the corresponding disc shear is damaged. When the drive cutter assembly rotates to replace the disc shear, the auxiliary frame slides along the auxiliary rod to the position corresponding to the damaged disc shear. Then, the auxiliary rod slides vertically downwards, allowing the auxiliary blade to replace the damaged disc shear in slitting the strip that continues to be fed forward. This ensures that the strip at this position continues to be slitted during the disc shear replacement process, thereby ensuring the continuity of the slitting operation. Once the disc shear is replaced and the slitting between the auxiliary blade and the disc shear is continuous, the auxiliary rod can be reset upwards, and the auxiliary blade awaits replacement of the next damaged disc shear for operation.
[0020] Furthermore, the upper end of the auxiliary frame is connected to an auxiliary slide frame that slides with the auxiliary rod. The two ends of the auxiliary rod are provided with support plates that are perpendicular and horizontally arranged to it. A screw parallel to the auxiliary rod is rotatably installed between the two support plates. The side wall of the auxiliary slide frame is provided with a protrusion that is threadedly connected to the screw. One end of the screw is connected to an auxiliary motor that drives its positioning rotation.
[0021] By adopting the above technical solution, the auxiliary rod is inserted into the auxiliary slide frame, enabling the auxiliary frame to be slidably mounted on the auxiliary rod, ensuring the stability of the auxiliary frame driving the auxiliary blade as a whole. When it is necessary to drive the auxiliary frame to move the auxiliary blade as a whole, the auxiliary motor drives the screw to rotate. Under the threaded connection between the screw and the protrusion, and the limiting and guiding effect of the auxiliary rod on the auxiliary slide frame, the protrusion drives the auxiliary slide frame, i.e., the entire auxiliary frame, to slide along the auxiliary rod. The number of rotations of the auxiliary motor can be set in advance according to the distance between the connected cutting blade assemblies to ensure that the auxiliary frame drives the entire auxiliary blade to move quickly and accurately to the position corresponding to the disc shear that needs to be replaced. This ensures that the auxiliary blade can replace the disc shear for cutting work when it is replaced, and ensures the consistency of the cutting work.
[0022] Furthermore, the detection assembly includes a detection frame parallel to the mounting rod and mounted on the slitting frame at both ends. A plurality of cameras are arrayed on the detection frame along its length. A light shield parallel to the detection frame and mounted on the slitting frame at both ends is provided below the detection frame. The lens of the camera faces the upper surface of the light shield. The camera is connected to a processor for communication feedback. The processor is connected to the cutting assembly and auxiliary components for communication feedback control.
[0023] By employing the above technical solution, a camera captures images of the metal narrow strip's slitting surface from top to bottom and feeds the image information back to the processor. The processor then analyzes the notches on the slitting surface using software to determine if the corresponding disc shears are damaged. When the disc shears are damaged, the processor communicates and controls the cutting assembly to replace the disc shears and have auxiliary components take over the longitudinal slitting work. This eliminates the need for manual assessment of the disc shears' damage, improving efficiency and accuracy, and thus ensuring the slitting quality of the metal narrow strip. A light shield, designed to work with the camera, is placed below the inspection frame to improve the accuracy of the metal narrow strip slitting surface images acquired by the camera and reduce interference from the surrounding environment.
[0024] Furthermore, the re-inspection assembly includes a re-inspection rod parallel to the mounting rod and mounted on the slitting frame at both ends. Several re-inspection frames, each corresponding to a cutter assembly and arranged vertically downwards, are arrayed along the length of the re-inspection rod. A re-inspection ring with an axis parallel to the re-inspection rod is detachably mounted on the lower end of the re-inspection frame. Sensors are embedded on both sides of the re-inspection ring. Several audible and visual alarms connected to the sensors for communication feedback control are provided on the re-inspection rod. Two sensors on each re-inspection ring are connected to the same audible and visual alarm.
[0025] By adopting the above technical solution, the cutting surface of the narrow metal strip and the sensor on the adjacent inspection ring are in contact. If the disc shear is not damaged, the sensor will detect a continuous straight line. If the sensor detects a discontinuous straight line, it indicates that there is a gap in the cutting surface of the narrow metal strip. The sensor feedback controls the corresponding audible and visual alarm to sound an alarm, reminding the staff to check and confirm. If both the detection component and the inspection component detect defects, it indicates that the disc shear is damaged. If only the auxiliary component is working and the inspection component detects defects, it indicates that the auxiliary component is damaged and needs to be replaced. In addition, if the auxiliary component is not working but only the inspection component detects defects, it can also remind the staff to manually verify the detection results of the detection component, avoiding missed or false detections.
[0026] Furthermore, a marking component is provided on the side of the re-inspection component away from the auxiliary component. The marking component includes a marking rod parallel to the re-inspection rod. Multiple vertically downward marking cylinders are arrayed on the marking rod along its length. The lower end of the piston rod of each marking cylinder is connected to a marking box, and a marking felt is installed at the bottom of the marking box. The number of marking cylinders is one more than the number of re-inspection rings, and the re-inspection ring is located between two adjacent marking cylinders. The sensor on the side wall of the re-inspection ring is connected to the marking cylinder closest to it for communication feedback control.
[0027] By adopting the above technical solution, the marking box contains marking ink that can wet the marking felt. When the re-inspection component detects a defect on the cutting surface of the metal narrow strip, the sensor on the corresponding re-inspection ring immediately sends a feedback signal to control the marking cylinder connected to it to work. The marking cylinder drives the corresponding marking box and marking felt to move downward. The marking felt marks the corresponding side defect position on the upper surface of the metal narrow strip so that the defect position can be processed when the metal narrow strip is used in the future.
[0028] Furthermore, a cleaning component is provided between the detection component and the cutting component, and between the re-inspection component and the auxiliary component. The cleaning component includes two cleaning rollers that are axially parallel to the mounting rod and arranged vertically. Each cleaning roller has a cleaning cavity arranged along its axial direction. On the side of the two cleaning rollers that are close to each other, there is a cleaning port that is arranged along its length and communicates with the corresponding cleaning cavity. A waste bin is provided on one side of the slitting frame. The waste bin is connected to the cleaning cavity through a suction pipe, and the suction pipe is connected to a suction fan.
[0029] By adopting the above technical solution, the suction fan draws air through the suction pipe, sucking the metal chips adhering to the upper and lower surfaces and side cut surfaces of the metal narrow strip into the waste bin from the cleaning port and cleaning chamber, thereby cleaning the metal narrow strip. On the one hand, this ensures that the surface of the metal narrow strip is flat and clean when it is wound up, avoiding scratches on the surface of the metal narrow strip by metal chips; on the other hand, it reduces the impact of metal chips on the detection components and re-inspection components, ensuring the accuracy of the detection results.
[0030] Furthermore, the cleaning roller is provided with guide plates located on both sides of the cleaning port and arranged along its length. The guide plates are inclined to form an "eight" shape, and the opening on the side near the corresponding cleaning port is smaller. At least one of the guide plates has a plurality of cleaning brushes arranged in an array along its length on the side wall near the cleaning port, which correspond one-to-one with the cutter assembly, and the cleaning brushes are arranged vertically.
[0031] By adopting the above technical solution, the inclined guide plate increases the opening of the cleaning port, ensuring that metal debris can be quickly sucked into the cleaning port. Furthermore, several cleaning brushes can sweep the cutting surface of the narrow metal strip during transport, improving the cleaning effect on the cutting surface and further reducing the impact of metal debris on the detection and re-inspection components, thus ensuring the accuracy of the detection results.
[0032] In summary, the present invention has the following beneficial effects:
[0033] 1. In this invention, a longitudinal shearing mechanism is provided, including a cutting component, a driving component, an auxiliary component, a detection component, and a re-inspection component. The driving component drives the cutting component to longitudinally slit the wide metal strip. The detection component detects whether there are gaps on the slit surface of the narrow metal strip and determines whether the working disc shear in the cutting component is damaged, such as chipping or nicks. If the disc shear is damaged, it is replaced, and the auxiliary component temporarily replaces the disc shear to perform the slit work, ensuring the continuity of the longitudinal shearing work. The re-inspection component inspects the slit surface of the narrow metal strip slit by the auxiliary component to determine whether the auxiliary component is damaged.
[0034] 2. In this invention, a plurality of cutting blade assemblies are provided on the mounting rod. Each cutting blade assembly includes a cutting blade ring and a plurality of cutting blades arranged in an array on the outer wall of the cutting blade ring. The end of the cutting blade away from the cutting blade ring is positioned and rotated to install the disc shear via a U-shaped clamp. Each cutting blade ring is clearance-fitted or interference-fitted with the mounting rod by a limiting component. The driving assembly includes a drive shaft, a drive gear, a driven gear, etc. The driven gear drives the corresponding disc shear to rotate via a first electromagnet and a disk. By rotating the mounting rod, the cutting blade assembly with interference fit with it rotates to replace the disc shear. Other cutting blade assemblies with clearance fit with it work normally. This achieves rapid replacement of the disc shear without pausing the longitudinal cutting operation or moving undamaged disc shears, improving blade replacement efficiency, reducing manual labor intensity, and improving safety.
[0035] 3. In this invention, a marking component is set on the side of the re-inspection component away from the auxiliary component. The marking component is used to mark the corresponding side defect position on the upper surface of the metal narrow strip so that the defect position can be processed when the metal narrow strip is used later.
[0036] 4. In this invention, cleaning components are provided between the detection component and the cutting component, and between the re-inspection component and the auxiliary component, to clean the metal chips adhering to the upper and lower surfaces and side cut surfaces of the metal narrow strip, ensuring that the surface of the metal narrow strip is flat and clean when it is wound up, avoiding scratches on the surface of the metal narrow strip by metal chips, and reducing the impact of metal chips on the detection results of the detection component and the re-inspection component, thus ensuring the accuracy of the detection results.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.
[0045] A quick-change slitting machine, such as Figure 1As shown, the device includes a feeding mechanism 01, a slitting mechanism 02, and a winding mechanism 03 arranged sequentially along the feeding direction. The feeding mechanism 01 releases the wide metal strip to be slitting, the slitting mechanism 02 slits the wide metal strip into narrow metal strips of appropriate width, and the winding mechanism 03 winds up the narrow metal strips. Both the feeding mechanism 01 and the winding mechanism 03 include a frame, a shaft, and a speed-regulating motor. Their basic structure and working principle are the same as in the prior art and are not innovative points of this invention, so they will not be described in detail.
[0046] like Figure 1 As shown, in this embodiment, the slitting mechanism 02 includes slitting frames 1 arranged opposite each other on both sides of the feeding direction. A mounting rod 2 is provided between the slitting frames 1, horizontally arranged perpendicular to the feeding direction. A plurality of cutting blade assemblies 3 are arrayed along the length of the mounting rod 2. A driving assembly 4 is provided on the slitting frames 1, cooperating with the plurality of cutting blade assemblies 3. The driving assembly 4 drives the plurality of cutting blade assemblies 3 to slit the wide metal strip into narrow metal strips of appropriate width. An auxiliary assembly 6 is also provided on the slitting frame 1 near the winding mechanism 03, and both the cutting blade assemblies 3 and the driving assembly 4 are located on the side of the auxiliary assembly 6 away from the winding mechanism 03. A detection assembly 5 is provided on the side of the auxiliary assembly 6 away from the winding mechanism 03, located between the auxiliary assembly 6 and the cutting blade assemblies 3. A re-inspection assembly 7 is provided on the side of the auxiliary assembly 6 near the winding mechanism 03. Additionally, a marking assembly 8 is provided on the side of the re-inspection assembly 7 away from the auxiliary assembly 6. Cleaning components 9 are provided between the detection assembly 5 and the cutting blade assemblies 3, and between the re-inspection assembly 7 and the auxiliary assembly 6.
[0047] like Figure 1 As shown, the metal strip cut by the cutting assembly 3 is conveyed forward. The detection assembly 5 checks for gaps on the cutting surface of the metal strip to determine if the disc shear 34 in the cutting assembly 3 is damaged, such as chipped blades or notches. If the disc shear 34 is damaged, it is replaced, and the auxiliary assembly 6 temporarily replaces the disc shear 34 to perform the cutting work, ensuring the continuity of the slitting operation. The re-inspection assembly 7 inspects the cutting surface of the metal strip cut by the auxiliary assembly 6. If both the detection assembly 5 and the re-inspection assembly 7 detect defects, it indicates that the disc shear 34 is damaged. If only the re-inspection assembly 7 detects defects, it indicates that the auxiliary assembly 6 is damaged and needs to be replaced. During this process, the marking assembly 8 marks the corresponding side defect location on the upper surface of the metal strip for subsequent treatment of the defect location during use. The cleaning component 9 is used to clean the metal chips adhering to the upper and lower surfaces and side cut surfaces of the metal narrow strip, ensuring that the surface of the metal narrow strip is flat and clean when it is wound up, avoiding scratches on the surface of the metal narrow strip by metal chips, and reducing the impact of metal chips on the detection results of the detection component 5 and the re-inspection component 7, thus ensuring the accuracy of the detection results.
[0048] Among them, such asFigure 1 As shown, a control console 04 is provided on one side of the slitting frame 1. The feeding mechanism 01, the cutting assembly 3, drive assembly 4, detection assembly 5, auxiliary assembly 6, re-inspection assembly 7, marking assembly 8, and cleaning assembly 9 in the slitting mechanism 02 are all connected to the control console 04 for communication feedback control. The control console 04 controls the automated operation or linkage of each mechanism or component through automatic control technology such as PLC, improving the overall automation level of the slitting machine. The automatic control technology such as PLC is the same as in existing technologies and will not be elaborated further. In addition, the slitting frame 1 is equipped with several guide rollers arranged along its width direction to facilitate the guiding and conveying of wide and narrow metal strips.
[0049] The detailed structure of each component is described below.
[0050] like Figure 2 As shown, in this embodiment, each cutting assembly 3 includes a cutting ring 31 coaxially arranged with the mounting rod 2. The outer wall of the cutting ring 31 is circumferentially arrayed with four cutting rods 32 arranged radially along its length. Each cutting rod 32 has a U-shaped clamp 33 detachably mounted at its end away from the cutting ring 31 via a snap-fit or threaded connection, with the opening of the U-shaped clamp 33 away from the cutting rod 32. A disc shear 34 with its axis parallel to the axis of the cutting ring 31 is rotatably mounted within the opening of each U-shaped clamp 33. During longitudinal cutting, one of the cutting rods 32 is vertically downward, and the disc shear 34 mounted at its lower end is in working condition, corresponding to and cooperating with the drive assembly 4. The drive assembly 4 drives the disc shear 34 to rotate and cut the wide metal strip.
[0051] like Figure 2 and Figure 3 As shown, the mounting rod 2 is rotatably mounted on the slitting frame 1 along its axial direction, and one end of it is connected to a replacement motor 21 that drives its positioning rotation. Several sets of limiting members 24 are arranged along the length of the mounting rod 2, each engaging with the inner wall of a number of cutting rings 31. Normally, the limiting members 24 are not in operation, and there is a clearance fit between the inner walls of the cutting rings 31 and the outer wall of the mounting rod 2, leaving the mounting rod 2 in a static position. The drive assembly 4 drives the several disc shears 34 of the worktable to rotate and position, cutting wide strips of metal. When the disc shear 34 needs to be replaced, the limiting member 24 corresponding to the cutting assembly 3 where the disc shear 34 is located will work, so that the inner wall of the corresponding cutting ring 31 and the outer wall of the mounting rod 2 are in an interference fit under the action of the limiting member 24. Then, the replacement motor 21 drives the mounting rod 2 to rotate the cutting assembly 3 that is in an interference fit with it, and rotates the other intact disc shears 34 on the cutting assembly 3 to the working state, so as to realize the quick replacement of the disc shear 34. The replacement process will not affect the normal operation of other cutting assemblies 3. After the replacement is completed, the limiting member 24 can be reset.
[0052] like Figure 3As shown, in this embodiment, each set of limiting members 24 includes several limiting rods 25 arranged in a circumferential array and radially along the mounting rod 2. One end of the limiting rod 25 away from the axis of the mounting rod 2 is connected to an arc-shaped block 26 that mates with the inner wall of the cutter ring 31. Several arc-shaped protrusions 261 are arranged in an array on the side of the arc-shaped block 26 near the inner wall of the cutter ring 31. Several limiting holes 22 that mate with the limiting rods 25 and clearance grooves 23 that mate with the arc-shaped blocks 26 are arranged in a circumferential array on the outer wall of the mounting rod 2. The limiting holes 22 and clearance grooves 23 are interconnected, and the clearance grooves 23 are located at the end of the limiting holes 22 away from the axis of the mounting rod 2. The limiting rods 25 are slidably installed in the limiting holes 22 and clearance grooves 23. A tension spring 27 and a cooperating second electromagnet 28 are provided between the end of the limiting rod 25 away from the arc-shaped block 26 and the end of the limiting hole 22 away from the clearance groove 23. The second electromagnet 28 has two symmetrically located on both sides of the tension spring 27.
[0053] like Figure 3 As shown, under normal conditions, the second electromagnet 28 is energized, and the arc-shaped block 26 and the arc-shaped protrusion 261 are completely located within the clearance groove 23, with a clearance fit between the cutter ring 31 and the mounting rod 2. When it is necessary to replace the disc shear 34, the second electromagnet 28 in the limiting assembly corresponding to the cutter ring 31 is de-energized. Under the action of the tension spring 27, several limiting rods 25 slide away from the axis of the mounting rod 2, so that the arc-shaped protrusion 261 on the arc-shaped block 26 abuts tightly against the inner wall of the cutter ring 31, realizing an interference fit between the inner wall of the corresponding cutter ring 31 and the outer wall of the mounting rod 2, ensuring that the rotation of the mounting rod 2 can drive the cutter assembly 3 to rotate and replace the disc shear 34. The arc-shaped protrusion 261 can be made of elastic material or have a large surface roughness to increase the friction between the inner wall of the cutter ring 31 and the outer wall of the mounting rod 2.
[0054] like Figure 2 and Figure 3As shown, in this embodiment, the drive assembly 4 includes a drive shaft 41 parallel to the mounting rod 2. Both ends of the drive shaft 41 are respectively positioned and mounted on corresponding slitting frames 1. A plurality of coaxially arranged drive gears 42 are arrayed along the length of the drive shaft 41, and one end of the drive shaft 41 is connected to a drive motor 411 that drives the plurality of drive gears 42 to rotate. A horizontal bar 43 parallel to the mounting rod 2 is also provided on one side. Both ends of the horizontal bar 43 are respectively mounted on corresponding slitting frames 1, and a plurality of vertically downward-arranged support plates 44 are arrayed along the length of the horizontal bar 43. Each support plate 44 has a driven gear 45 rotatably mounted near its lower sidewall, corresponding one-to-one with each of the drive gears 42. The axis of the driven gear 45 is arranged along the length of the horizontal bar 43, and a transmission chain 47 is provided between each pair of corresponding drive gears 42 and driven gears 45 for transmission. Each driven gear 45 is located on one side of the disc shear 34. A disk 35 is mounted on the rotating shaft of the corresponding disc shear 34 on the side of the U-shaped clamp 33 near the corresponding driven gear 45. A first electromagnet 46 that cooperates with the disk 35 is provided on the side of the driven gear 45 near the disk 35.
[0055] like Figure 2 and Figure 3 As shown, during slitting operation, the drive motor 411 controls the drive shaft 41 to drive several drive gears 42 to rotate in a positioning position. Under the transmission action of the transmission chain 47 on the corresponding drive gears 42 and driven gears 45, several driven gears 45 are driven to rotate synchronously. Under the action of the first electromagnet 46 on each driven gear 45 being energized and attracted and fixed to the corresponding disk 35, each driven gear 45 drives the corresponding disc shear 34 to rotate, thereby causing the disc shears 34 working in several cutting assemblies 3 to rotate synchronously to slit and cut the wide metal strip. When it is necessary to replace a damaged disc shear 34, at the same time as the corresponding limiting member 24 is working, the first electromagnet 46 on the driven gear 45 that cooperates with it is de-energized, releasing the fixing effect between the damaged disc shear 34 and the corresponding driven gear 45, so that the mounting rod 2 can drive the cutting assembly 3 to rotate to replace the disc shear 34 without affecting the normal operation of other cutting assemblies 3.
[0056] like Figure 1 and Figure 3As shown, by setting up the mounting rod 2, cutter assembly 3, limiting component 24, and drive assembly 4 as described above, the damaged disc shear 34 can be quickly replaced. During the replacement process, other cutter assemblies 3 will not rotate with the mounting rod 2, and the auxiliary assembly 6 will temporarily take over the longitudinal slitting work. This eliminates the need to pause the longitudinal slitting operation or move undamaged disc shear 34s during replacement, improving blade changing efficiency, reducing manual labor intensity, and enhancing safety. Damaged disc shear 34s can be replaced uniformly after the longitudinal slitting operation is completed, requiring only the removal of the U-shaped clamp 33, without directly disassembling the disc shear 34, further improving safety. If multiple disc shear 34s in the cutter assembly 3 fail consecutively, it indicates a problem with the longitudinal slitting operation; in this case, the longitudinal slitting operation should be paused and readjusted.
[0057] like Figure 3 As shown, in this embodiment, to improve the service life of the disc shear 34 and reduce the possibility of damage, a cotton felt 331 is provided on the inner wall of the U-shaped clamp 33 near the cutter bar 32. During the rotation of the disc shear 34, the outer periphery of the cotton felt 331 is always in contact with the disc shear 34. An annular oil storage cavity 311 is provided inside the cutter ring 31. Each cutter bar 32 has an oil supply channel 321 arranged along its length and communicating with the annular oil storage cavity 311. An oil supply hole 332 communicating with the oil supply channel 321 is provided on the side wall of the U-shaped clamp 33 located between the cotton felt 331 and the cutter bar 32, and the oil supply hole 332 penetrates the side wall of the U-shaped clamp 33 near the cotton felt 331. Additionally, an oil filling hole 312 communicating with the annular oil storage cavity 311 is provided on the outer wall of the cutter ring 31, and a plug 313 is provided at the end of the oil filling hole 312 away from the annular oil storage cavity 311.
[0058] like Figure 3 As shown, lubricating oil is introduced into the annular oil storage chamber 311. The lubricating oil is delivered from the oil supply channel 321 on the vertically downward cutting bar 32 through the oil supply hole 332 on the corresponding U-shaped clamp 33 and absorbed by the cotton felt 331 inside the U-shaped clamp 33. The disc shear 34 on the vertically downward cutting bar 32 is in working state. When the disc shear 34 rotates to cut the metal strip, the disc shear 34 is in continuous contact with the cotton felt 331. The cotton felt 331 can coat the disc shear 34 with lubricating oil, reduce the wear of the disc shear 34 and improve the service life of the disc shear 34. On the other hand, it can wipe and clean the disc shear 34 to prevent the disc shear 34 from being covered with debris, which will not only affect the cutting effect of the disc shear 34 on the metal strip, but also affect the service life of the disc shear 34. When the lubricating oil in the annular oil storage chamber 311 is insufficient, the plug 313 can be removed to open the oil filling hole 312 and add lubricating oil to the annular oil storage chamber 311 to ensure that the cotton felt 331 absorbs sufficient lubricating oil to lubricate the disc shear 34.
[0059] like Figure 1 and Figure 4As shown, in this embodiment, the auxiliary component 6 includes an auxiliary rod 61 parallel to the mounting rod 2 and vertically slidably mounted on the slitting frame 1 at both ends. The auxiliary rod 61 is connected to an auxiliary cylinder 611 that drives it to slide vertically back and forth. An auxiliary frame 62 that slides along its length and is vertically arranged is provided on the auxiliary rod 61. An auxiliary blade 63 is rotatably mounted at the lower end of the auxiliary frame 62, and the axis of the auxiliary blade 63 is parallel to the axis of the disc shear 34. An auxiliary sliding frame 621 that slides and engages with the auxiliary rod 61 is connected to the upper end of the auxiliary frame 62. The auxiliary sliding frame 621 is slidably sleeved outside the auxiliary rod 61, and the side wall of the auxiliary sliding frame 621 is provided with a protrusion 622 integrally formed therewith. Support plates 612 that are perpendicular to and horizontally arranged at both ends of the auxiliary rod 61 are provided. A screw 64 that is parallel to the auxiliary rod 61 and threadedly connected to the protrusion 622 is rotatably mounted between the two support plates 612, and one end of the screw 64 is connected to an auxiliary motor 641 that drives it to rotate in a position.
[0060] like Figure 1 and Figure 4 As shown, when the detection component 5 continuously detects a notch in the cut surface after slitting, it indicates that the corresponding disc shear 34 is damaged. Simultaneously, while the drive cutter assembly 3 rotates to replace the disc shear 34, the auxiliary motor 641 drives the screw 64 to rotate, thereby driving the auxiliary frame 62 to slide along the auxiliary rod 61 to the position corresponding to the damaged disc shear 34. Then, the auxiliary cylinder 611 drives the auxiliary rod 61 to slide vertically downwards, allowing the auxiliary blade 63 to replace the damaged disc shear 34 in slitting the continuously conveying strip. This ensures that the strip at this position continues to be slitted during the replacement of the disc shear 34, thus ensuring the continuity of the slitting operation. Once the disc shear 34 is replaced and the slitting between the auxiliary blade 63 and the disc shear 34 is continuous, the auxiliary rod 61 can be reset upwards, and the auxiliary blade 63 awaits replacement of the next damaged disc shear 34 for operation.
[0061] like Figure 1 and Figure 5 As shown, in this embodiment, the detection component 5 includes a detection frame 51 parallel to the mounting rod 2 and mounted on the slitting frame 1 at both ends. A plurality of cameras 52 are arrayed along the length of the detection frame 51. A light-shielding plate 53, parallel to the detection frame 51 and mounted on the slitting frame 1 at both ends, is located below the detection frame 51. The lenses of the cameras 52 face the upper surface of the light-shielding plate 53. A narrow metal strip passes between the cameras 52 and the light-shielding plate 53. The cameras 52 are connected to a processor 54 located on the control console 04 via communication feedback. The processor 54 is connected to the cutter assembly 3 and the auxiliary assembly 6 via communication feedback control.
[0062] like Figure 1 and Figure 5As shown, the camera 52 captures images of the metal narrow strip cutting surface from top to bottom and feeds the image information back to the processor 54. The processor 54 analyzes the notches on the metal narrow strip cutting surface using software to determine if the corresponding disc shear 34 is damaged. When the disc shear 34 is damaged, the processor 54 communicates and controls the cutting assembly 3 to replace the disc shear 34 and the auxiliary assembly 6 to replace the longitudinal shearing work. This eliminates the need for manual judgment of the disc shear 34's damage, improving judgment efficiency and accuracy, thereby ensuring the cutting quality of the metal narrow strip. The camera 52 can be a CCD camera, and the processor 54's image acquisition and processing for defect analysis is a mature technology and will not be elaborated further.
[0063] like Figure 1 and Figure 6 As shown, in this embodiment, the re-inspection assembly 7 includes re-inspection rods 71 parallel to the mounting rod 2 and mounted on the slitting frame 1 at both ends. Several re-inspection frames 72, corresponding one-to-one with the cutting blade assemblies 3 and arranged vertically downwards, are arrayed along the length of the re-inspection rods 71. Re-inspection rings 73 with axes parallel to the re-inspection rods 71 are detachably mounted on the lower end of the re-inspection frame 72. Sensors 74 are embedded on both sides of the re-inspection rings 73. In addition, the re-inspection rods 71 are also equipped with several audible and visual alarms 75 that are connected to the sensors 74 for communication feedback control, and the two sensors 74 on each re-inspection ring 73 are connected to the same audible and visual alarm 75.
[0064] like Figure 1 and Figure 6 As shown, the cutting surface of the narrow metal strip and the adjacent inspection ring 73 are in contact with the sensor 74. If the disc shear 34 is not damaged, the sensor 74 will sense a continuous straight line. If the sensor 74 senses a discontinuous straight line, it indicates that there is a gap in the cutting surface of the narrow metal strip. The sensor 74 will then control the corresponding audible and visual alarm 75 to sound an alarm, reminding the staff to check and confirm. If both the detection component 5 and the inspection component 7 detect defects, it indicates that the disc shear 34 is damaged. If only the inspection component 7 detects defects when the auxiliary component 6 is working, it indicates that the auxiliary component 6 is damaged and needs to be replaced. In addition, if the auxiliary component 6 is not working but only the inspection component 7 detects defects, it can also remind the staff to manually verify the detection results of the detection component 5 to avoid missed or false detections by the detection component 5.
[0065] like Figure 1 and Figure 4As shown, in this embodiment, the cleaning assembly 9 includes two cleaning rollers 91 arranged vertically and axially parallel to the mounting rod 2. Each cleaning roller 91 has a cleaning cavity 911 arranged axially within it. On the side of the two cleaning rollers 91 that are close to each other, there is a cleaning port 912 arranged along its length and communicating with the corresponding cleaning cavity 911. A waste bin 94 is provided on one side of the slitting frame 1. The waste bin 94 is connected to the cleaning cavity 911 via a suction pipe 95, and the suction pipe 95 is connected to a suction fan 96. The suction fan 96 draws air through the suction pipe 95, sucking metal chips adhering to the upper and lower surfaces and side cut surfaces of the metal strip into the waste bin 94 from the cleaning port 912 and the cleaning cavity 911, thus cleaning the metal strip and ensuring a smooth and clean surface during winding. This also reduces the impact of metal chips on the detection results of the detection assembly 5 and the re-inspection assembly 7.
[0066] Among them, such as Figure 4 and Figure 5 As shown, to further improve the cleaning effect of the cleaning component 9, guide plates 92 are provided on the cleaning roller 91, located on both sides of the cleaning port 912 and arranged along its length. The two guide plates 92 on each cleaning roller 91 are inclined to form an "eight" shape, and the opening on the side near the corresponding cleaning port 912 is smaller, thus increasing the opening of the cleaning port and ensuring that metal debris can be quickly sucked into the cleaning port. In addition, at least one guide plate 92 has a plurality of cleaning brushes 93 arranged in an array along its length on the side wall near the cleaning port 912, corresponding one-to-one with the cutter component 3. The cleaning brushes 93 are arranged vertically, and the cleaning brushes 93 are used to sweep the cutting surface of the metal narrow strip during the conveying process, thereby improving the cleaning effect on the cutting surface of the metal narrow strip.
[0067] like Figure 1 and Figure 6 As shown, in this embodiment, the marking assembly 8 includes a marking rod 81 parallel to the re-inspection rod 71. Multiple vertically downward-facing marking cylinders 82 are arrayed along the length of the marking rod 81. The lower end of the piston rod of each marking cylinder 82 is connected to a marking box 83 containing marking ink. A marking felt 84 is installed at the bottom of the marking box 83, and the marking ink in the marking box 83 impregnates the marking felt 84. The number of marking cylinders 82 is one more than the number of re-inspection rings 73, and the re-inspection ring 73 is located between two adjacent marking cylinders 82. A sensor 74 on the side wall of the re-inspection ring 73 is connected to the nearby marking cylinder 82 for communication feedback control. When the re-inspection assembly 7 detects a defect on the metal narrow strip's cutting surface, the sensor 74 on the corresponding re-inspection ring 73 immediately sends a feedback signal to control the marking cylinder 82 connected to it. The marking cylinder 82 drives the corresponding marking box 83 and marking felt 84 to move downwards. The marking felt 84 marks the corresponding side defect location on the upper surface of the metal narrow strip, so that the defect location can be processed during subsequent use of the metal narrow strip.
[0068] Working principle and method of use of the present invention:
[0069] The feeding mechanism 01 releases the wide metal strip to be longitudinally cut. The longitudinal cutting mechanism 02 longitudinally cuts the wide metal strip into narrow metal strips of appropriate width. The winding mechanism 03 winds up the narrow metal strips. When the longitudinal cutting mechanism 02 is working, the drive assembly 4 drives several cutting blade assemblies 3 to longitudinally cut the wide metal strip into narrow metal strips of appropriate width. If the detection assembly 5 detects continuous notches on the cutting surface of the narrow metal strip, it indicates that the corresponding disc shear 34 is damaged and needs to be replaced.
[0070] When the disc shear 34 needs to be replaced, the limiting member 24 corresponding to the cutting assembly 3 containing the disc shear 34 is activated, and the corresponding second electromagnet 28 is de-energized. Under the action of the tension spring 27, the arc-shaped protrusion 261 on the arc-shaped block 26 tightly abuts against the inner wall of the cutting ring 31, so that the inner wall of the corresponding cutting ring 31 and the outer wall of the mounting rod 2 are in an interference fit under the action of the limiting member 24. Then, the replacement motor 21 drives the mounting rod 2 to rotate the cutting assembly 3 with which it is in an interference fit, rotating the other intact disc shears 34 on the cutting assembly 3 to the working state, realizing the rapid replacement of the disc shear 34, and the normal operation of other cutting assemblies 3 will not be affected during the replacement process. After the replacement is completed, the limiting member 24 can be reset.
[0071] Meanwhile, when replacing the disc shear 34, the auxiliary motor 641 drives the screw 64 to rotate, driving the auxiliary frame 62 to slide along the auxiliary rod 61 to the position corresponding to the damaged disc shear 34. Then, the auxiliary cylinder 611 drives the auxiliary rod 61 to slide vertically downwards, allowing the auxiliary blade 63 to replace the damaged disc shear 34 in cutting the strip that continues to be conveyed forward. This ensures that the strip at this position continues to be cut during the replacement of the disc shear 34, thus ensuring the continuity of the slitting operation. Once the disc shear 34 is replaced and the slitting between the auxiliary blade 63 and the disc shear 34 is continuous, the auxiliary rod 61 can be reset upwards, and the auxiliary blade 63 awaits replacement of the next damaged disc shear 34 for operation.
[0072] When the re-inspection component 7 detects a defect on the cutting surface of the metal narrow strip, the sensor 74 on the corresponding re-inspection ring 73 immediately sends a feedback signal to control the marking cylinder 82, which is connected to it. The marking cylinder 82 drives the corresponding marking box 83 and marking felt 84 to move downwards. The marking felt 84 marks the corresponding side defect position on the upper surface of the metal narrow strip so that the defect position can be processed during subsequent use of the metal narrow strip. If only the auxiliary component 6 is working and the re-inspection component 7 continuously detects defects, the operator needs to inspect the auxiliary component 6 to determine whether the auxiliary blade 63 is damaged.
