Description

Technical Field

[0001] This utility model relates to the technical field of insulating film processing equipment, and in particular to an insulating film cutting device. Background Technology

[0002] Insulating films are widely used in transformer high and low voltage windings and other fields. Their slitting and cutting must ensure cutting accuracy and film surface integrity. Existing cutting devices generally have the following problems: 1. Poor component coordination: In traditional equipment, the unwinding, tensioning, traction, cutting and rewinding components are controlled independently, which leads to sudden changes in the tension of the insulating film during process transitions, which can easily cause the film material to loosen or be overstretched.

[0003] 2. Insufficient dynamic tension control: Common tensioning mechanisms use fixed pressure rollers or motors for active tensioning, which cannot respond to changes in membrane tension in real time, resulting in wrinkles or tears in the insulating film of the cut section.

[0004] 3. Deformation of the pressure roller causes cutting defects: When the pressure roller of the traction component is adjusted for lifting and lowering, it is easy to bend due to uneven pressure at both ends, causing local unbalanced clamping force on the insulating film, which in turn leads to burrs or curling edges when the cutting component is cutting. Utility Model Content

[0005] To overcome the problems of poor continuity, poor tension stability, and poor cutting quality in the existing technology of insulating film roll cutting, which leads to defects such as loose film, wrinkles, and curling edges, this utility model provides an insulating film cutting device. The device uses a frame to coordinate five components for unwinding, tensioning, traction, cutting, and rewinding, combined with a self-weight swing roller for tensioning, a roller synchronous pressure roller, and a rotating cutter, to achieve continuous and stable conveying of insulating film, wrinkle-free stretching, and high-precision, curl-free cutting.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an insulating film cutting device, including a frame; an unwinding assembly and a winding assembly symmetrically arranged on both sides of the frame, each of the unwinding and winding assemblies including a frame plate, a roller rotatably mounted on the frame plate, and a first motor for driving the roller to rotate; a tensioning assembly located on the upper part of the frame, including a bracket swayably mounted on the frame and a swing roller located at the end of the bracket and abutting against the upper surface of the insulating film, the swing roller applying downward pressure to the insulating film by the weight of the bracket; and a tensioning assembly located behind the tensioning assembly. The traction assembly includes a horizontally mounted idler roller on the frame, a second motor driving the idler roller to rotate, a pressure roller located above the idler roller that can be raised and lowered, and a second drive cylinder driving the pressure roller to rise and fall; the cutting assembly located behind the traction assembly includes a cross brace spanning the frame, a cutter that can reciprocate along the cross brace, a third motor driving the cutter to move, a pressure bar located on the side of the cross brace that can be raised and lowered, and a fourth cylinder driving the pressure bar to rise and fall; the unwinding assembly, tensioning assembly, traction assembly, cutting assembly and rewinding assembly cooperate in sequence to complete the slitting and cutting of the insulating film.

[0007] In the above-mentioned insulating film cutting device, the upper part of the frame plate of the unwinding assembly and the winding assembly is provided with a straight groove-shaped slide rail, and the two ends of the roller shaft are slidably installed in the slide rail through bearings; the outer side of the frame plate is provided with a liftable support block and a first drive cylinder for driving the support block to lift and lower, and the support block is used to support the roller shaft to enter and exit the slide rail.

[0008] In the aforementioned insulating film cutting device, the winding assembly and the unwinding assembly have a mirror-symmetrical structure.

[0009] In the aforementioned insulating film cutting device, the tensioning assembly has a buffer inside its frame that limits the swing amplitude of the swing roller.

[0010] In the aforementioned insulating film cutting device, the two ends of the pressure roller of the traction component are connected to guide rods through roller plates, and sliders fixed to the roller plates are sleeved on the guide rods. The cylinder rod of the second drive cylinder is connected to the roller plate.

[0011] The aforementioned insulating film cutting device further includes a traction assembly comprising a wheel frame located on the upper part of the frame, a roller installed below the wheel frame and abutting against the middle of the pressure roller, and a third drive cylinder for driving the wheel frame to rise and fall.

[0012] In the aforementioned insulating film cutting device, the back of the cutting component is equipped with a miniature motor that drives its rotation.

[0013] In the aforementioned insulating film cutting device, the pressure strip is made of elastic rubber material.

[0014] In the aforementioned insulating film cutting device, the first drive cylinder, the second drive cylinder, the third drive cylinder, and the fourth cylinder are any one of hydraulic cylinders, pneumatic cylinders, or electric cylinders.

[0015] In the aforementioned insulating film cutting device, the first motor is a servo motor, the second motor is a frequency converter motor, and the third motor is a stepper motor.

[0016] The beneficial effects of this utility model are: 1. Five-component coordinated operation: Through the unwinding component, tensioning component, traction component, cutting component and rewinding component arranged in sequence on the frame, the continuous conveying and cutting of insulating film is integrated, eliminating sudden tension changes during process transition and ensuring stable operation of the film material.

[0017] 2. Dynamic tension self-adaptation: The bracket and the weight of the swing roller apply downward pressure to the insulating film. The swing roller automatically swings to adjust the pressure according to the change of film tension, and balances the tension in real time to avoid the film being too tight and tearing or too loose and wrinkling.

[0018] 3. Anti-deformation design of pressure roller: The traction assembly is equipped with a roller that abuts against the middle of the pressure roller and a third drive cylinder that drives it to rise and fall synchronously. This balances the force on the pressure roller, prevents uneven pressing of the insulating film caused by bending deformation, and ensures that the cutting section is flat and burr-free.

[0019] 4. Optimized anti-deviation cutting: The elastic pressure strip presses down to fix the insulating film during cutting, preventing curling edges; the reciprocating and rotating combined motion of the cutter improves cutting efficiency and cross-sectional quality. Attached Figure Description

Detailed Implementation

[0030] In this embodiment, the insulating film cutting device has a reasonable overall design and a compact structure, such as... Figure 1-8As shown, the main components include a frame 1 that provides basic support. An unwinding assembly 2 and a rewinding assembly 3 for insulating film are respectively installed on both sides of the frame 1. A tensioning assembly 4, a traction assembly 5, and a cutting assembly 6 are also arranged sequentially on the upper part of the frame 1. These components cooperate to achieve the slitting and cutting operation of the insulating film. The unwinding assembly 2 is the starting part of the insulating film cutting device, and its function is to provide a stable supply of insulating film for subsequent cutting processes. The unwinding assembly 2 includes a frame plate 21, a roller 22, a first drive cylinder 23, a support block 24, and a first motor 25. The frame plate 21 is symmetrically arranged on both sides of the frame 1. On the side, the frame plate 21 is made of high-strength steel to ensure that it can bear the weight of the roller 22 and the insulating film. The frame plate 21 is connected to the frame 1 by bolts. This connection method is not only easy to install, but also easy to disassemble, which facilitates subsequent maintenance and repair. The upper part of the frame plate 21 is provided with a straight groove-shaped slide 26. The width and depth of the slide 26 are carefully designed to ensure that the roller 22 can slide smoothly in it, and to ensure that the roller 22 will not wobble during rotation. The design of the slide 26 makes the loading and unloading of the roller 22 more convenient and improves work efficiency.

[0031] A first motor 25 is arranged on the outer side of one of the support plates 21. The first motor 25 is the power source of the unwinding assembly 2, and its performance directly affects the unwinding effect of the insulating film. The first motor 25 is a high-performance servo motor, which has the advantages of stable speed and fast response. The first motor 25 is used to drive the roller shaft 22 to rotate. The output shaft of the first motor 25 is provided with a retainer that engages with the roller shaft 22. The retainer has a through-hole straight slot. The end of the roller shaft 22 has a key that matches the straight slot. When the first motor 25 rotates, the power is transmitted to the roller shaft 22 through the engagement of the key and the straight slot, so that the roller shaft 22 can rotate stably. To facilitate the unwinding of the insulating film, bearings are fitted at both ends of the roller 22, which can slide along the slide rail 26. These bearings are made of high-quality materials, possessing wear-resistant and corrosion-resistant properties, ensuring smooth sliding of the roller 22 within the slide rail 26, reducing friction, and extending the service life of both the roller 22 and the slide rail 26. A vertically movable support block 24 is arranged on one side of the slide rail 26. The support block 24 is made of high-strength metal with a smooth surface to reduce friction with the roller 22. The support block 24 assists in the loading and unloading operations of the roller 22. When installing the roller 22, it is placed on the support block 24, and the roller 22 is unwound by the lifting and lowering of the support block 24. The roller 22 is fed into the slide rail 26; when disassembling the roller 22, the support block 24 rises to lift the roller 22, making it easier for the operator to remove the roller 22. A first drive cylinder 23 is vertically arranged on one side of the support block 24 to drive its lifting and lowering. The cylinder body of the first drive cylinder 23 is fixed to the frame plate 21 by bolts. This connection method is firm and reliable, and can withstand the force generated by the first drive cylinder 23 during operation. The cylinder rod of the first drive cylinder 23 is connected to the support block 24, thereby driving the support block 24 to perform lifting and lowering operations. To improve the stability of the support block 24 during vertical lifting and lowering, a slider 56 and a slide rail can be added to the back of the support block 24. The slider 56 cooperates with the slide rail to make the support block 24 more stable and stable. Block 24 can move smoothly along the slide rail during the lifting process, avoiding swaying or deviation of the support block 24 during the lifting process. The first drive cylinder 23 can be selected as a hydraulic cylinder, pneumatic cylinder or electric cylinder according to actual needs. Different drive cylinders have different characteristics. Hydraulic cylinders have the advantages of large output force and smooth operation, and are suitable for occasions with high output force requirements. Pneumatic cylinders have the advantages of fast response speed and simple structure, and are suitable for occasions with high response speed requirements. Electric cylinders have the advantages of high precision and convenient control, and are suitable for occasions with high precision requirements. In practical applications, the appropriate drive cylinder can be selected according to specific production needs and cost budget.

[0032] The winding assembly 3 has the same structure as the unwinding assembly 2 and is arranged in a mirror image on the other side of the frame 1. The function of the winding assembly 3 is to wind up the cut insulating film for subsequent storage and transportation. The working principle of the winding assembly 3 is similar to that of the unwinding assembly 2. The motor drives the roller shaft 22 to rotate, and the insulating film is wound on the roller shaft 22. The roller shaft 22, bearings, support blocks 24, drive cylinder and other components of the winding assembly 3 are made of the same materials and have the same performance as those of the unwinding assembly 2 to ensure the stability and reliability of the winding process. During the winding process, the winding speed and tension need to be adjusted according to the thickness and width of the insulating film to ensure that the wound insulating film roll is neat and tight, without looseness or wrinkles. The tensioning assembly 4 is a key component in the insulating film cutting device to ensure the tension of the insulating film. Its function is to maintain the appropriate tension of the insulating film during the cutting process to avoid the insulating film from becoming loose or too tight, which would affect the cutting quality.

[0033] The tensioning assembly 4 includes a bracket 41, a swing roller 42, and a buffer 43. The bracket 41 is H-shaped and arranged inside the frame 1. The bracket 41 is welded from high-strength steel and has sufficient strength and rigidity to bear the weight of the swing roller 42 and the insulating film. One end of the bracket 41 is connected to the frame 1 through a bearing seat, allowing the bracket 41 to swing around the frame 1. The bearing seat is made of high-quality material and contains high-precision bearings to ensure the flexibility and stability of the swing of the bracket 41. The other end of the bracket 41 is equipped with the swing roller 42, which is connected to the bracket 41 through the bearing seat. The swing roller 42 abuts against the upper surface of the insulating film. The swing roller 42 is made of lightweight, high-strength material and has a smooth surface to reduce friction with the insulating film. The weight of the bracket 41 and the swing roller 42 applies downward pressure to the insulating film, keeping it in a tensioned state. As the tension of the insulating film changes, the swing roller 42... Roller 42 can swing around frame 1 with the help of bracket 41 according to the traction force from the insulating film to achieve tension balance operation. When the tension of the insulating film increases, roller 42 will swing upward to reduce the downward pressure on the insulating film; when the tension of the insulating film decreases, roller 42 will swing downward to increase the downward pressure on the insulating film, thereby maintaining the tension of the insulating film. In order to prevent roller 42 from exceeding the lowest point of frame 1 when tensioned, causing wear on the insulating film, a buffer 43 is arranged inside frame 1. The buffer 43 is a hydraulic buffer 43 or a rubber buffer 43. When roller 42 swings to the lowest point, buffer 43 can play a buffering and limiting role, reducing the impact force of roller 42 on frame 1, and preventing roller 42 from directly contacting frame 1, thereby protecting the insulating film from wear. The installation position and buffering force of buffer 43 are carefully designed and adjusted to ensure that roller 42 will not damage the insulating film during swing.

[0034] The traction assembly 5 is a key component in the insulating film cutting device for conveying the insulating film. Its function is to transport the insulating film from the unwinding assembly 2 to the cutting assembly 6, and to ensure the stability and accuracy of the insulating film during the conveying process. The traction assembly 5 includes a roller 51, a second motor 52, a pressure roller 53, a roller plate 54, a guide rod 55, a slider 56, a second drive cylinder 57, a third drive cylinder 58, a wheel frame, and rollers 59. The roller 51 is horizontally placed inside the frame 1 and connected to it at both ends through bearing seats. The roller 51 is made of high-strength steel and has a smooth surface to reduce friction with the insulating film. The diameter and length of the roller 51 are designed according to the width of the insulating film and the conveying speed to ensure that the insulating film can be conveyed smoothly. The second motor 52 is connected by bolts. Located on the outside of the frame 1, the second motor 52 is the power source for the traction assembly 5. Its performance directly affects the conveying speed and stability of the insulating film. The second motor 52 is a high-performance variable frequency motor, which has the advantages of adjustable speed and smooth operation. The output shaft of the second motor 52 is keyed to one end of the idler roller 51, and the two idler rollers are connected by a belt drive, which enables the second motor 52 to transmit power to the idler roller 51, driving the idler roller 51 to rotate. The belt drive has the advantages of smooth transmission and low noise, which can ensure the stable speed of the idler roller 51, thereby ensuring the stable conveying speed of the insulating film. Above the idler roller 51, there are height-adjustable pressure rollers 53 arranged side by side. The function of the pressure rollers 53 is to cooperate with the idler roller 51 to apply a certain pressure to the insulating film, so that the insulating film can be... The rollers are tightly fitted onto the idler roller 51 to achieve stable conveying. Roller plates 54 are arranged on both sides of the pressure roller 53. The roller plates 54 are connected to the pressure roller 53 through bearing seats. The roller plates 54 are made of high-strength steel and can withstand the pressure of the pressure roller 53 and the insulating film. A guide rod 55 connected to the frame 1 is vertically arranged on the outer side of the roller plate 54. The guide rod 55 is made of high-precision steel and the surface is smoothed to ensure that the slider 56 can slide smoothly on the guide rod 55. The upper part of the guide rod 55 is fitted with a slider 56 connected to the roller plate 54, so that the roller plate 54 can perform directional vertical lifting and lowering operations along the surface of the guide rod 55 with the help of the slider 56. A second drive cylinder 57 is also arranged on the upper part of the frame 1. The cylinder body of the second drive cylinder 57 is connected to the frame 1 by bolts. The second drive cylinder 57 is connected to the roller plate 54 via a nut. The second drive cylinder 57 drives the roller plate 54 to move up and down, thereby adjusting the traction distance between the pressure roller 53 and the support roller 51 to accommodate insulating films of different thicknesses. When the thickness of the insulating film changes, the stroke of the second drive cylinder 57 is adjusted to match the distance between the pressure roller 53 and the support roller 51 with the thickness of the insulating film, ensuring that the insulating film can pass smoothly through the traction assembly 5. Since the pressure roller 53 is only subjected to the pressure of the second drive cylinders 57 at both ends, it is prone to deformation due to uneven force, which could lead to a collision with the support roller 51. Therefore, a vertically downward wheel frame is added to the upper part of the frame 1. The wheel frame is bolted to the frame 1 and is made of high-strength steel.Capable of withstanding the pressure of rollers 59 and pressure rollers 53, rollers 59 are arranged below the wheel frame to abut against the pressure rollers 53. Rollers 59 are made of high-quality materials with smooth surfaces to reduce friction with the pressure rollers 53. The rollers 59 apply downward pressure to the central area of ​​the pressure rollers 53, ensuring relatively uniform force distribution across the entire pressure roller and preventing deformation. Since the pressure rollers 53 undergo vertical lifting and lowering adjustments, a third drive cylinder 58 is added to the upper part of the frame 1. The cylinder body of the third drive cylinder 58 is bolted to the frame 1, and the cylinder rod is connected to the wheel frame via a nut. This allows the third drive cylinder 58 to drive the wheel frame with rollers 59 to perform vertical lifting and lowering operations, enabling the rollers 59 to move in the same direction as the pressure rollers 53. Thus, regardless of how the pressure rollers 53 rise and fall, the rollers 59 always maintain contact with the pressure rollers 53, providing uniform downward pressure.

[0035] The cutting assembly 6 is the core component of the insulating film cutting device. Its function is to cut the insulating film to a predetermined size. The cutting assembly 6 includes a cross brace 61, a third motor 62, a clamping plate 63, a cutter 64, a fourth cylinder 65, and a pressure bar 66. The cross brace 61 is horizontally placed between the frames 1 and fixed at both ends with bolts. The cross brace 61 is made of high-strength steel and can withstand the force generated by the cutter 64 and the cutting process. The cutter 64, which can reciprocate along its arrangement direction, is arranged below the cross brace 61. The cutter 64 is made of high-hardness alloy material and has a sharp cutting edge, which can quickly and accurately cut the insulating film. A third motor 62 is arranged at one end of the cross brace 61. The third motor 62 is connected to the cross brace 61 by bolts. The third motor 62 is the power source of the cutting assembly 6, and its performance directly affects the reciprocating speed and cutting effect of the cutter 64. The third motor 62 is a high-performance stepper motor, which has the advantages of stable speed and high positioning accuracy. Both the output end of the third motor 62 and the other end of the cross brace 61 are equipped with pulleys. A belt connected to the cutter 64 is arranged on the outside of the pulleys. A clamping plate 63 bolted to the belt is arranged on the top of the cutter 64. The belt is driven by the pulleys through the third motor 62. The cross brace 61 rotates internally, which in turn drives the cutter 64 to reciprocate linearly via the connected clamping plate 63. A micro motor can be added to the back of the cutter 64 to drive the circular cutter 64 to rotate. When the cutter 64 rotates while reciprocating, it can improve cutting efficiency and quality, and reduce burrs and deformation generated during the cutting process. To prevent the insulating film from curling during the cutting process, a pressure strip 66 is arranged on one side of the cross brace 61 for pressing the insulating film during the cutting process. The pressure strip 66 is made of high-strength rubber material, which has a certain degree of elasticity and softness, and can press the insulating film. The process of cutting the film will not damage the insulating film. A fourth cylinder 65 is also arranged on the side of the cross brace 61. The cylinder body of the fourth cylinder 65 is connected to the cross brace 61 by bolts, and the cylinder rod of the fourth cylinder 65 is connected to the pressure bar 66 by nuts. This allows the fourth cylinder 65 to drive the pressure bar 66 to perform vertical lifting and lowering operations on one side of the cross brace 61. During cutting, the fourth cylinder 65 drives the pressure bar 66 to descend and press the insulating film onto the frame 1 to prevent the insulating film from moving or curling during the cutting process. During the conveying of the insulating film, the fourth cylinder 65 drives the pressure bar 66 to rise to avoid interfering with the pressing operation of the insulating film.

[0036] The insulating film cutting device of this embodiment can achieve efficient and stable cutting of insulating film through the coordinated work of its components. In practical applications, the parameters of each component can be adjusted and optimized according to different insulating film specifications and production needs to meet different production requirements. At the same time, the device also has the advantages of simple structure, convenient operation and low maintenance cost, and has high practical value and market promotion prospects.

[0037] In operation, the operator first activates the first drive cylinder 23, causing the support block 24 to rise vertically to a suitable height. After the support block 24 is in place, the roller 22 containing the insulating film to be cut is carefully placed on the support block 24, ensuring that the groove key of the roller 22 is aligned with the support position on the surface of the support block 24, so that the roller 22 can be placed stably. The height of the support block 24 is slowly adjusted to send the roller 22 into the slide rail 26 of the frame plate 21. During the sending process, it is necessary to closely observe whether the bearings at both ends of the roller 22 can slide smoothly in the slide rail 26. If jamming occurs, the position of the support block 24 should be adjusted in time or the slide rail 26 should be checked. Check for foreign objects. After the roller 22 is fully inserted into the slide 26, engage the holder of the first motor 25 with the end of the roller 22 to ensure that the keyway and the straight groove fit tightly, so that the first motor 25 can stably transmit power to the roller 22. The installation steps of the take-up roller 22 are similar to those of the unwind roller 22. First, start the first drive cylinder 23 on one side of the take-up assembly 3 to raise the support block 24, place the empty take-up roller 22 on the support block 24, and send the take-up roller 22 into the slide 26 of the take-up assembly 3 frame plate 21, and engage its end with the holder of the take-up assembly 3 to ensure a firm connection, thus preparing for the subsequent take-up operation.

[0038] Then, start the second motor 52, which drives the idler roller 51 to rotate via belt drive. Simultaneously, operate the second drive cylinder 57 to slowly lower the pressure roller 53, gradually bringing it closer to the idler roller 51. During the descent of the pressure roller 53, carefully observe the gap between the pressure roller 53 and the idler roller 51. When the gap approaches the thickness of the insulating film, pull the insulating film from the unwinding roller shaft 22, pass it under the swing roller 42 of the tensioning assembly 4, and then introduce it between the pressure roller 53 and the idler roller 51 of the traction assembly 5. Continue adjusting the second drive cylinder 57 to... The pressure roller 53 and the support roller 51 apply appropriate pressure to the insulating film to ensure that the insulating film can be stably pulled and conveyed. At this time, observe the swing roller 42 of the tensioning component 4. The swing roller 42 will swing automatically according to the tension of the insulating film. If the swing roller 42 swings too much, it means that the tension of the insulating film may be too high or too low. The swing roller 42 can be kept in a relatively stable balance position by adjusting the motor speed of the unwinding component 2 or the winding component 3, or by finely adjusting the stroke of the second drive cylinder 57, so that the swing roller 42 is in a relatively stable balance position and the tension of the insulating film is appropriate.

[0039] Then start the third motor 62, which drives the cutter 64 to reciprocate along the cross brace 61 via belt drive. Observe whether the movement of the cutter 64 is smooth and whether there is any jamming or abnormal noise. If any abnormality is found, the motor should be stopped immediately and the belt should be checked for looseness and whether the cutter 64 is installed securely. After troubleshooting, restart the motor and then operate the fourth cylinder 65 to lower the pressure strip 66 to contact the surface of the frame 1. Check whether the pressure of the pressure strip 66 on the frame 1 is uniform. If the pressure is not uniform, the installation position of the fourth cylinder 65 can be adjusted or the pressure strip 66 itself can be checked for deformation or other problems to ensure that the pressure strip 66 can evenly press the insulating film during cutting and prevent the insulating film from curling.

[0040] Once the traction, tension, and cutting components 6 of the insulating film are debugged, the cutting operation can begin. The operator determines the cutting position of the cutter 64 according to the predetermined cutting size. This can be done by setting marks on the frame 1 or by using measuring tools to assist in determining the position. After confirming that all components are operating normally, the entire device is started, allowing the insulating film to be continuously conveyed under the drive of the traction component 5. When the insulating film is conveyed to the predetermined cutting position, the cutter 64 reciprocates under the drive of the third motor 62. At the same time, the micro motor drives the cutter 64 to rotate (if the cutter 64 is equipped with a micro motor) to cut the insulating film. During the cutting process, the fourth cylinder 65 maintains the pressure strip 66 in a pressing state on the insulating film to ensure the cutting quality.

[0041] During the cutting process, operators must closely observe the cutting situation and pay attention to the cutting effect of the cutter 64, such as whether the cut surface is flat and whether there are burrs. At the same time, they should observe whether the insulation film is conveyed smoothly and whether the tension remains stable. If poor cutting quality or abnormal insulation film conveying is found, the device should be stopped immediately, and the fault should be checked and eliminated. For example, if burrs appear on the cut surface, it may be that the cutting edge of the cutter 64 has become dull and needs to be replaced. If the insulation film conveying is stuck, it may be that the pressure between the pressure roller 53 and the idler roller 51 of the traction component 5 is too high or the insulation film itself has quality problems and needs to be adjusted accordingly.

[0042] As the cutting process continues, the cut insulating film will be continuously wound onto the take-up roller 22. The operator must observe the winding process to ensure that the insulating film is neatly and tightly wound onto the take-up roller 22. If the winding is not neat, it may be due to a mismatch between the motor speed of the take-up assembly 3 and the motor speed of the traction assembly 5, or a deviation in the installation position of the take-up roller 22. Adjustments should be made in a timely manner. The motor torque of the take-up assembly 3 should be adjusted according to the diameter of the insulating film to ensure stable tension of the insulating film during the winding process. As the diameter increases, the motor torque should be gradually reduced to avoid deformation or damage to the insulating film due to excessive tension. After one roll of insulating film is cut, the device should be stopped. The first drive cylinder 23 on one side of the take-up assembly 3 should be operated to raise the support block 24 and remove the wound insulating film roll from the take-up roller 22. Then, the above steps for installing the take-up roller 22 should be repeated to install a new empty take-up roller 22 for the cutting and winding operation of the next roll of insulating film.

[0043] Through the usage methods described above, operators can fully utilize the various functions of this insulating film cutting device to achieve efficient and high-quality cutting of insulating films, meeting different production needs.
