Description

Technical Field

[0001] This application relates to the field of thin film production technology, and more specifically, to an edge-trimming machine. Background Technology

[0002] Film capacitors are capacitors that use plastic film as the dielectric. The production process typically involves melt extrusion, filtration, stretching, edge trimming, corona treatment, winding, and packaging. Edge guide rollers are key components specifically designed for the slitting and edge-gathering process, combining slitting and edge-gathering functions with guiding and supporting functions. They ensure smooth transport of the roll material during slitting and assist in edge material collection, playing a crucial role in improving slitting accuracy, edge-gathering effect, and production efficiency.

[0003] Regarding the demand for product diversification, the market's requirements for the specifications and dimensions of film capacitors are becoming increasingly diverse. Different film specifications result in significant differences in the width and length of the edge material generated during the slitting process. Existing edge material guide rollers have poor versatility and cannot adapt to the edge material collection needs generated from slitting various film specifications. When producing wide-width films, the edge material length exceeds the guide roller's load-bearing capacity, easily causing edge material breakage and entanglement with the cutting tools. This not only affects slitting accuracy but may also damage the slitting tools, increasing production costs. Conversely, for narrow-width film slitting, the longer guide roller length cannot fully utilize the equipment's operating efficiency, resulting in resource waste. Utility Model Content

[0004] The purpose of this application is to provide an edge-gathering machine, wherein the edge guide roller can extend the length to meet the edge-gathering requirements of film edge materials of different specifications.

[0005] In a first aspect, embodiments of this application provide an edge-collecting machine, which includes a receiving roller and an edge guide roller. The edge guide roller includes a roller body, and both ends of the roller body are coaxially connected to blocking portions. The diameter of the blocking portions is larger than the diameter of the roller body. The axial length of the edge guide roller is 170~220mm, the axial length of the roller body accounts for 70%~80%, and the axial length of the blocking portions accounts for 20%~30%. The axial direction of the edge guide roller is parallel to the axial direction of the receiving roller. The edge guide roller is configured to be able to translate relative to the receiving roller in the axial direction, so that continuous edge material passes around the edge guide roller and is wound onto the receiving roller.

[0006] In the above-described process, the edge material bypasses the edge material guide roller and, guided by the edge material guide roller, is wound onto the take-up roller. During continuous take-up, the edge material guide roller moves relative to the take-up roller in an axial translational manner. Under the guidance of the edge material guide roller, the edge material can be wound to different positions on the take-up roller, achieving uniform take-up. In this embodiment, by adjusting the overall length of the edge material guide roller and controlling the length ratio of the roller body to the blocking part, the edge material guide roller designed in this way can achieve length extension to meet the edge-taking requirements of film edge materials of different specifications.

[0007] This edge guide roller is used in the edge-collecting machine during the production of film capacitors. Edge material passes around the roller, which can rotate to guide it. The effective working length of the edge guide roller can be flexibly adjusted within the range of 170mm to 220mm. Extensive experimental verification shows that when the length of the edge guide roller is less than 170mm, its load-bearing capacity is insufficient, easily leading to edge material entanglement and misalignment. Conversely, a length exceeding 220mm results in excessive rotational inertia, significantly increasing equipment energy consumption and reducing response speed. In terms of structural design, the lengths of the two ends (blocking sections) and the middle section (roller body) of the edge guide roller are optimized. The length of the ends (blocking sections) accounts for 20%~30% of the total length, while the length of the middle section (roller body) accounts for 70%~80%. This ratio ensures a stable connection between the edge guide roller and the transmission components while reserving sufficient space for edge material transport, avoiding insufficient effective working area in the middle section due to excessively long ends, or installation stability problems caused by excessively short ends.

[0008] In one possible implementation, the edge guide roller is coaxially sleeved on the fixed shaft, and the edge guide roller is rotatable, with a bearing provided between the fixed shaft and the blocking part.

[0009] In the above process, the edge guide roller is installed through a fixed shaft, and bearings are used to make it rotate smoothly on the fixed shaft.

[0010] In one possible implementation, the diameter of the bearing is 30-40 mm; and / or, a retaining ring is provided between the bearing and the blocking part.

[0011] In one possible implementation, the drive end of the drive mechanism is coaxially connected to a fixed shaft, the fixed shaft is fixedly inserted into the inner ring of the bearing, and a retaining ring is provided between the bearing and the blocking part.

[0012] In the above process, the edge guide roller is installed through a fixed shaft, and bearings are used to make it rotate smoothly on the fixed shaft.

[0013] In one possible implementation, it includes at least two edge guide rollers, all of which are axially parallel and arranged in layers, and all of which are positioned in front of the take-up roller, so that continuous edge material passes around each of the edge guide rollers in sequence and is finally wound onto the take-up roller.

[0014] In one possible implementation, the edge guide roller and the take-up roller are arranged side by side, the length of the edge guide roller is 170~220mm, and the length of the take-up roller is 200~300mm; And / or, when viewed along the conveying direction of the edge material, the diameter of the roller body of each edge material guide roller gradually increases.

[0015] In the above process, the edge material guide rollers and the receiving rollers cooperate with each other. By controlling the number and position of the edge material guide rollers, the edge material can be received evenly, and the jamming phenomenon during receiving can be reduced.

[0016] In one possible implementation, it further includes a movable bed, on which the take-up roller is mounted for synchronous translation, and the position of the edge guide roller is fixed, wherein the translation of the edge guide roller relative to the take-up roller is achieved by the translation of the take-up roller.

[0017] In the above implementation process, the take-up roller is mounted on the moving bed and is movable, while the position of the edge guide roller is fixed to achieve smooth guidance. Only by moving the take-up roller can all the edge guide rollers be translated relative to the take-up roller.

[0018] In one possible implementation, the diameter of the roller body is 30-50 mm; the diameter of the blocking part is 60-100 mm.

[0019] In the above implementation process, the diameter of the control roller and the diameter of the blocking part are controlled within a certain range. The diameter of the roller is smaller, which reduces weight and rotational resistance while ensuring structural strength. The diameter of the blocking part is larger. When the blocking part is used, it needs to be matched with the bearing. The thickened design is adopted to enhance the tightness of the fit between the blocking part and the bearing and improve the wear resistance.

[0020] In one possible implementation, the diameter ratio of the blocking portion to the roller body is 1.2:1 to 1.4:1.

[0021] In the above implementation process, the diameter ratio of the end (blocking part) and the middle section (roller body) of the edge material guide roller is controlled between 1.2:1 and 1.4:1. This ratio optimizes the mechanical property distribution of the edge material guide roller, making the torque transmission more efficient during equipment operation, significantly reducing vibration and noise, improving overall operational stability and extending service life.

[0022] In one possible implementation, the roller body has an axial channel, the blocking portion has an axial through hole, the diameter of the through hole being larger than the diameter of the channel, and the diameter of the through hole being smaller than the diameter of the roller body.

[0023] In the above implementation process, the roller body and the blocking part adopt the above specific structure, the channel and the through hole are connected to facilitate the setting of the fixed shaft and realize the installation of the edge material guide roller; and the through hole is made according to a certain size specification to facilitate the addition of bearings and ensure the overall strength.

[0024] In one possible implementation, the diameter of the through hole in the blocking part is 30-40 mm; the diameter of the channel in the roller body is 20-30 mm.

[0025] In the above process, better relaxation can be achieved.

[0026] In one possible implementation, the edge guide roller is integrally formed, and / or the edge guide roller is made of aluminum.

[0027] In the above process, the edge material guide roller is integrally formed, resulting in good integrity; the edge material guide roller is made of aluminum, which reduces the overall weight. Attached Figure Description

[0038] First Embodiment Please refer to Figure 1This embodiment provides an edge-collecting machine, which includes a receiving roller 210 and an edge guide roller 100. The axial direction of the edge guide roller 100 is parallel to the axial direction of the receiving roller 210. The edge guide roller 100 is configured to be able to translate axially relative to the receiving roller 210, so that continuous edge material 230 passes around the edge guide roller 100 and is wound onto the receiving roller 210.

[0039] In this embodiment, the edge material 230 passes around the edge material guide roller 100 and is wound onto the take-up roller 210 under the guidance of the edge material guide roller 100. During the continuous take-up process, the edge material guide roller 100 moves relative to the take-up roller 210 in a axial translation manner. Under the guidance of the edge material guide roller 100, the edge material 230 can be wound onto different positions of the take-up roller 210 to achieve uniform take-up.

[0040] Please refer to the following: Figure 2 The edge guide roller 100 includes a roller body 110, with blocking portions 120 coaxially connected to both ends of the roller body 110. The diameter of the blocking portions 120 is larger than the diameter of the roller body 110. The axial length of the edge guide roller 100 is 170~220mm, the axial length of the roller body 110 accounts for 70%~80%, and the axial length of the blocking portions 120 accounts for 20%~30%. For example, the axial length of the edge guide roller 100 is 170mm, 180mm, 190mm, 200mm, 210mm, 220mm, or any intermediate value between any two of the above values; the axial length percentage of the roller body 110 is 70%, 72%, 75%, 77%, 80%, or any intermediate value between any two of the above values; correspondingly, the axial length percentage of the blocking portions 120 is 30%, 28%, 250%, 23%, 20%, or any intermediate value between any two of the above values.

[0041] In this embodiment, the structure of the edge guide roller 100 is roller body 110 (middle section) + blocking part 120 (both ends). In this embodiment, by adjusting the overall length of the edge guide roller 100 and controlling the length ratio of the roller body 110 and the blocking part 120, the edge guide roller 100 designed in this way can achieve length extension to meet the edge-gathering requirements of different specifications of film edge materials.

[0042] The edge guide roller 100 is used in the edge-gathering machine during the production of film capacitors. The edge material passes around the edge guide roller 100, which can rotate to provide guidance. The effective working length of the edge guide roller 100 can be flexibly adjusted within the range of 170mm to 220mm. Extensive experimental verification shows that when the length of the edge guide roller 100 is less than 170mm, its load-bearing capacity for the edge material is insufficient, and edge material entanglement and deviation are likely to occur. On the other hand, when the length exceeds 220mm, the rotational inertia of the edge guide roller 100 becomes too large, significantly increasing the equipment's energy consumption and reducing its response speed.

[0043] In terms of structural design, the lengths of the two ends (blocking parts 120) and the middle section (roller body 110) of the edge guide roller 100 have an optimized proportional relationship. The length of the ends (blocking parts 120) accounts for 20% to 30% of the total length, and the length of the middle section (roller body 110) accounts for 70% to 80% of the total length. This ratio can ensure a stable connection between the edge guide roller 100 and the transmission components, and also reserve sufficient space for edge material transmission. This avoids insufficient effective working area of ​​the middle section due to excessively long ends, or installation stability problems caused by excessively short ends.

[0044] In some embodiments of this application, the diameter of the roller body 110 is 30-50 mm; the diameter of the blocking portion 120 is 60-100 mm. For example, the diameter of the roller body 110 is 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, or any intermediate value between any two of the above values; the diameter of the blocking portion 120 is 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, or any intermediate value between any two of the above values.

[0045] In this embodiment, the diameter of the control roller 110 and the diameter of the blocking part 120 are within a certain range. The diameter of the roller 110 is reduced by 10% to 15% compared to the diameter of the same area of ​​a conventional guide roller, thereby reducing weight and rotational resistance while ensuring structural strength. The diameter of the blocking part 120 is increased by 15% to 25% compared to the diameter of the same area of ​​a conventional guide roller. When the blocking part 120 is used, it needs to cooperate with the bearing. The thickened design is adopted to enhance the tightness of the fit between the blocking part 120 and the bearing and improve the wear resistance.

[0046] In some embodiments of this application, the diameter ratio of the blocking portion 120 to the roller body 110 is 1.2:1 to 1.4:1. Exemplarily, the diameter ratio of the blocking portion 120 to the roller body 110 is 1.2:1, 1.3:1, 1.4:1, or an intermediate value between any two of the above ratios.

[0047] In this embodiment, the diameter ratio of the end (blocking part 120) and the middle section (roller body 110) of the edge guide roller 100 is controlled to be between 1.2:1 and 1.4:1. This ratio optimizes the mechanical property distribution of the edge guide roller 100, making the torque transmission more efficient during equipment operation, significantly reducing vibration and noise. Compared with the traditional structure, the overall operating stability is improved by more than 30%, and the service life is extended by 40%.

[0048] In some embodiments of this application, the roller body 110 has an axial channel 111, and the blocking portion 120 has an axial through hole 121. The diameter of the through hole 121 is larger than the diameter of the channel 111, and the diameter of the through hole 121 is smaller than the diameter of the roller body 110.

[0049] In this embodiment, the roller body 110 and the blocking part 120 adopt the specific structure described above. The channel 111 and the through hole 121 are connected to facilitate the installation of the fixed shaft and realize the installation of the edge material guide roller 100. The through hole 121 is made of a certain size specification to facilitate the addition of bearings and to ensure the overall strength.

[0050] In some embodiments of this application, the diameter of the through hole 121 of the blocking part 120 is 30-40 mm; the diameter of the channel 111 of the roller body 110 is 20-30 mm. For example, the diameter of the through hole 121 of the blocking part 120 is 30 mm, 32 mm, 35 mm, 37 mm, 40 mm, or any intermediate value between two of the above values; the diameter of the channel 111 of the roller body 110 is 20 mm, 22 mm, 25 mm, 28 mm, 30 mm, or any intermediate value between two of the above values.

[0051] In this embodiment, compared to a conventional guide roller, the diameter of the inner ring (channel 111) of the roller body 110 is reduced, and the inner ring (through hole 121, which corresponds to the outer ring of the corresponding bearing) of the blocking part 120 is enlarged to achieve better expansion.

[0052] In some embodiments of this application, the edge guide roller 100 is integrally formed, and / or the edge guide roller 100 is made of aluminum.

[0053] In this embodiment, the edge guide roller 100 is integrally formed, resulting in good overall integrity; the edge guide roller 100 is replaced with aluminum instead of the traditional ABS, reducing the overall weight.

[0054] In some embodiments of this application, the axial direction is horizontal, the edge guide roller 100 is coaxially sleeved on the fixed shaft, and the edge guide roller 100 is rotatable. A bearing is provided between the fixed shaft and the blocking part 120.

[0055] In this embodiment, the edge guide roller 100 is installed via a fixed shaft and rotates smoothly on the fixed shaft using bearings.

[0056] In some embodiments of this application, the diameter of the bearing is 30-40 mm; and / or, the fixed shaft is inserted into the inner ring of the bearing and fixed together with the bearing, and a retaining ring is provided between the outer ring of the bearing and the through hole 121 of the blocking part 120.

[0057] In this embodiment, the bearing specifications correspond to the specifications of the inner ring (through hole 121) of the blocking part 120. Viewed from the end face of the edge guide roller 100, the combination from the center to the outer ring is: fixed shaft - bearing - snap ring - edge guide roller 100, ensuring the operation of the edge guide roller 100.

[0058] In some embodiments of this application, it includes at least two edge guide rollers 100, all edge guide rollers 100 are axially parallel and arranged in layers, and all edge guide rollers 100 are arranged in front of the take-up roller 210, so that the continuous edge material 230 passes around each edge guide roller 100 in sequence, and under the guidance of the edge guide rollers 100, finally winds onto the take-up roller 210.

[0059] In some embodiments of this application, when viewed along the conveying direction of the edge material 230, the diameter of the roller body 110 of each edge material guide roller 100 gradually increases, that is, the edge material guide rollers 100 are arranged in a stepped manner.

[0060] In this embodiment, multiple edge guide rollers 100 cooperate with the take-up roller 210. By controlling the number and position of the edge guide rollers 100, the edge material 230 is collected evenly, and the jamming phenomenon during collection can be reduced. The reasons are as follows: From a structural perspective, the edge guide rollers 100 adopt a stepped layered arrangement, which prevents the edge material 230 from piling up randomly and forces it to be arranged in layers, avoiding the formation of "entanglement knots". From a dynamic perspective, the conical stepped arrangement of the edge guide rollers 100 causes the linear velocity of the edge material 230 to change along the axial direction (the linear velocity is higher at the large diameter end). The edge material 230 produces slight slippage during winding, automatically adjusting the packing density. From a system perspective, the stepped arrangement structure of the edge guide rollers 100, together with the winding tension and the guiding mechanism, changes the edge material 230 collection process from "passive piling up" to "active and orderly guidance".

[0061] In some embodiments of this application, the edge guide roller 100 and the take-up roller 210 are arranged side by side. The length of the edge guide roller 100 is 170~220mm, and the length of the take-up roller 210 is 200~300mm. For example, the edge guide roller 100 may be 200mm, 220mm, 250mm, 270mm, 300mm, or any intermediate value between the two values ​​mentioned above; the length of the take-up roller 210 may be 200mm, 220mm, 250mm, 270mm, 300mm, or any intermediate value between the two values ​​mentioned above.

[0062] In this embodiment, the length of the edge guide roller 100 can be adapted to the edge-gathering requirements of different specifications of film edge material 230 (5~110mm), and the length of the take-up roller 210 is larger. With the relative translation of the edge guide roller 100, the edge material 230 is evenly rolled onto the take-up roller 210.

[0063] In some embodiments of this application, it also includes a movable bed 220 that can be moved, a take-up roller 210 that is mounted on the movable bed 220 to achieve synchronous translation, and the position of the edge guide roller 100 is fixed. The edge guide roller 100 is translated relative to the take-up roller 210 by the translation of the take-up roller 210.

[0064] In this embodiment, the take-up roller 210 is mounted on the moving bed 220 and is movable, while the position of the edge guide roller 100 is fixed to achieve smooth guidance. Only by moving the take-up roller 210 can all the edge guide rollers 100 be translated relative to the take-up roller 210.

[0065] Traditional 70mm edge guide rollers, due to their limited length, can only handle a small amount of edge material at a time. At a slitting speed of 400m / min, this results in a shutdown for cleaning after an average of 120 minutes of operation due to edge material accumulation, reducing the effective operating time of the production line to only 75%. However, by using edge guide rollers with extended lengths of 170-220mm, the edge material capacity is nearly doubled, allowing for continuous operation for 300 minutes without cleaning. This increases the effective operating time of the production line to 92%, and equipment capacity is increased by 68% compared to before the upgrade. The main optimizations are as follows.

[0066] (1) Optimization of contact area: from “surface contact” to “line contact + layered guidance”.

[0067] Traditional straight cylindrical guide rollers have a contact mode where the edge material contacts the entire circumferential surface, resulting in a frictional resistance characteristic of a large frictional area and a linearly increasing resistance. In the embodiment of this application, the edge material guide rollers have a contact mode where the edge material contacts the edge material at the stepped ridges, and each stepped segment is wrapped in layers, resulting in a frictional resistance characteristic of a 30% to 40% reduction in contact area and a significant reduction in frictional resistance.

[0068] (2) Tension distribution adjustment: the “tension self-balancing” effect of the conical stepped arrangement.

[0069] Structural design: The edge material guide rollers are arranged in a conical gradient (e.g., the feed end has a small diameter and the discharge end has a large diameter). When the edge material is wound, the tension difference is generated due to the change in diameter. The mechanical principle is that the tension is greater when the edge material is wound at the small diameter end and less at the large diameter end. The conical step arrangement forces the edge material tension to self-adjust along the axial direction, avoiding local over-tightness. When the edge material passes through the stepped transition zone, the increased diameter leads to a larger winding radius, according to the formula F= (Centripetal force formula) The tension F decreases as the radius r increases, thereby relieving the compressive stress of the inner edge material.

[0070] (3) The stepped arrangement of the edge guide rollers in the edge trimming machine has a synergistic effect with the whole machine system.

[0071] Matching with the winding tension control system: The diameter change of the stepped layered guide rollers can serve as a tension feedback signal: When the edge material is wound in the large-diameter stepped section, the winding motor automatically reduces its speed to avoid sudden tension changes and further reduce jamming.

[0072] Optimization of edge material guiding mechanism: Edge trimming machines are usually equipped with edge material guide rollers and pressure rollers. The ridges of the stepped guide rollers can form a "positioning groove" with the guide rollers, forcing the edge material to wind along the stepped trajectory and avoiding deviation and accumulation.

[0073] Cutting precision reaches its peak: When producing ultra-thin films, the edge offset drops sharply from ±0.3mm to ±0.05mm, achieving a qualitative leap in cutting precision. The product qualification rate jumps to over 90%, fully meeting the almost demanding precision requirements of the high-end market for ultra-thin film capacitors. This has successfully opened the door to the high-end market and won more high-quality orders.

[0074] The equipment is highly adaptable: thanks to its stepped arrangement and extended length structure, it can easily handle the winding of various film edge materials, from narrow to wide widths and from regular to ultra-thin. The time for switching between different film specifications has been significantly reduced from 30 minutes to 10 minutes, greatly improving production flexibility and efficiency. This allows for rapid response to diverse market demands and enhances the company's market competitiveness.

[0075] In summary, the edge-gathering machine of this application embodiment can achieve length extension and meet the edge-gathering requirements of film edge materials of different specifications.
