Non-inversion type edge cutting device for electrolytic copper foil production machine

Abstract

A non-overturning edge cutting device for an electrolytic copper foil maker is disclosed, which comprises a rough adjustment locking mechanism and a radial feed micro-adjusting screw to make the cutting knife close to the foil surface, a rotating axial micro-adjusting screw assembly to align the cutting knife edge with the cutting knife roll slot, and a cutting knife feed to the cutting foil position to start the edge cutting. When the radial feed micro-adjusting screw is rotated, the position of the scale pointer on the radial micro-adjusting scale is observed to control the cutting knife feed amount. The axial and radial screws are rotated to realize the cutting knife alignment and feed function, avoiding the heavy work of overturning the cutting knife part when the overturning cutting knife is fed, effectively avoiding the safety risk of the cutting knife edge facing the operator during overturning, avoiding the wear of the cutting knife edge, realizing the standardization of the cutting knife feed, being convenient to operate, saving the labor cost and the use cost of the cutting knife, and improving the production efficiency.

Description

Technical Field

[0001] This invention relates to the field of electrolytic copper foil production, and in particular to a non-flipping edge-cutting device for an electrolytic copper foil production machine. Background Technology

[0002] Electrolytic copper foil is one of the fundamental materials in the electronics industry, primarily used in the manufacture of copper-clad laminates (CCLs), conductive materials for printed circuit boards (PCBs), and is an indispensable raw material for lithium battery cathodes. During the electrolytic copper foil production process, the copper foil produced by the cathode rollers is prone to edge oxidation and thickening at the edges, resulting in burrs. During winding, the copper foil is prone to edge curling, leading to loosening and wrinkling, affecting the quality of the foil roll. Therefore, an edge-trimming device is needed to trim the edges of the produced foil.

[0003] The existing edge-cutting devices in copper foil production machines are mainly rotary edge-cutting devices. During the blade feeding and retraction, the heavy-duty cutting blade, cutting shaft, cutting blade support, coupling, motor, and protective cover—a series of edge-cutting components—require manual rotation. These components typically weigh 3-10 kg. Rotating these components is a physically demanding task for copper foil production machine operators, and the exposed blade edge poses a safety hazard. Furthermore, the inability to quantify the cutting depth during blade feeding leads to severe wear on the blade and groove, resulting in reduced blade life and frequent copper foil tearing, ultimately impacting copper foil production.

[0004] Chinese Patent Publication No. CN111086039A discloses an online copper foil cutting device for a copper foil production machine. This online copper foil cutting device requires manual flipping of the cutter, which increases the workload of manual labor and also poses safety hazards. Summary of the Invention

[0005] To overcome the shortcomings of existing edge-cutting devices, such as bulkiness and lack of quantification leading to reduced cutter life and frequent copper foil tearing, this invention proposes a non-flipping edge-cutting device for electrolytic copper foil production machines.

[0006] This invention includes a mounting bracket, a radial fine-tuning mechanism, a radial fine-tuning locking mechanism, a radial coarse-tuning locking screw, an axial adjustment mechanism, a cutter rotation mechanism, and a cutter. The upper surface of the mounting bracket has a first linear guide rail and a second linear guide rail that are parallel to each other. The coarse-tuning connecting plate and the axial adjustment connecting plate of the radial coarse-tuning locking mechanism are respectively mounted on the first and second linear guide rails via a first slider, a second slider, a third slider, and a fourth slider. The upper surface of the coarse-tuning connecting plate has a radial fine-tuning fixing seat, and the upper surface of the axial adjustment connecting plate has a radial fine-tuning nut. One end of the radial fine-tuning screw is placed in a screw groove on the upper surface of the radial fine-tuning fixing seat, and the other end of the radial fine-tuning screw is connected to the nut hole of the radial fine-tuning nut. A rotating handle is installed at the radial fine-tuning fixing seat end of the radial fine-tuning screw. The coarse-tuning connecting plate and the axial adjustment connecting plate are rigidly connected by the radial fine-tuning screw. The radial fine-tuning locking mechanism is located on the upper surface of the coarse-tuning connecting plate and the axial-tuning connecting plate, and one end of the radial fine-tuning locking plate in the radial fine-tuning locking mechanism is fixed on the axial-tuning connecting plate, while the strip-shaped adjustment hole at the other end is fitted onto the fine-tuning locking screw located on the coarse-tuning connecting plate.

[0007] There is a radial feed coarse adjustment limit block on the side surface of the mounting bracket.

[0008] A radial feed fine-tuning scale is provided on the side surface of the mounting support, and a scale pointer is provided on the surface of the axial adjustment connecting plate above the radial feed fine-tuning scale. During feed, the radial feed amount is controlled by the position of the feed fine-tuning scale pointer on the radial feed fine-tuning scale, so as to accurately control the position of the cutter.

[0009] A radial coarse adjustment locking plate is located on one side surface of the coarse adjustment connecting plate, and a radial coarse adjustment locking screw is located on the radial coarse adjustment locking plate. After the coarse adjustment connecting plate is adjusted into place, the radial coarse adjustment locking screw is tightened against the side surface of the mounting bracket to achieve locking and positioning of the coarse adjustment connecting plate.

[0010] The axial adjustment mechanism is located on the upper surface of the axial adjustment connecting plate. Three vertical support plates are arranged on the upper surface of the axial adjustment connecting plate, with one end being the adjusting screw support plate; the other two support plates are guide shaft support plates. Each of the three support plates has coaxial through holes for mounting the axial adjusting screw and guide shaft, respectively. The center lines of the through holes on the three support plates are parallel to the axis of the cutter rotation mechanism.

[0011] The through hole for mounting the guide shaft is machined with a clamping groove, and the two ends of the clamping groove are located at the 3 o'clock and 9 o'clock positions of each through hole, respectively.

[0012] The guide shaft is installed in the through holes of the two support plates, and the guide shaft and the through holes are axially slidingly fitted. To prevent the guide shaft from rotating during operation, a guide key is provided on the circumferential surface of the guide shaft. Limit blocks are respectively placed on the upper surface of the two guide shaft support plates. When the guide shaft is adjusted to the correct position, the limit blocks are tightened by bolts, thereby axially locking the multi-cover guide shaft and causing the set screw to press against the surface of the guide key.

[0013] A connecting plate is installed at the outer end of the guide shaft. One end of the connecting plate is fixed to the end face of the guide shaft, and the other end is mounted on the cutter shaft of the cutter rotation mechanism via a bearing.

[0014] The inner end of the axial adjusting screw is threadedly connected to the outer end of the guide shaft. The axial adjusting screw is mounted in the through hole of the adjusting screw support plate via a bearing and is positioned by a shaft retaining ring.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] This invention involves loosening the coarse adjustment locking mechanism, manually moving all components on the linear guide to the limit block position and locking them; loosening the radial fine adjustment locking mechanism, rotating the radial feed fine adjustment screw to bring the cutter closer to the foil surface, rotating the axial fine adjustment screw assembly to align the cutter blade with the cutter roller groove, and starting the cutter rotation button to begin cutting; rotating the radial feed fine adjustment screw and observing that the scale pointer points to the specified position on the radial fine adjustment scale, the cutter will also feed to the foil cutting position and begin cutting the edge.

[0017] This invention enables blade alignment and feed by rotating axial and radial screws, avoiding the cumbersome work of flipping the blade component during feed in traditional flip-type blades, saving operator effort, and also avoiding the safety risk of the blade facing the operator during flipping. To address blade wear caused by uneven feed depth, a graduated feed system is designed, standardizing the blade feed. This invention saves operator effort, avoids safety risks, prevents blade wear caused by inconsistent feed depth, saves labor and blade operating costs, and improves production efficiency.

One end of the radial fine adjustment screw 5 is placed in the screw groove on the upper surface of the radial fine adjustment fixing seat, and the other end of the radial fine adjustment screw 5 is connected to the nut hole of the radial fine adjustment nut 13. A rotating handle is installed at the radial fine adjustment fixing seat end of the radial fine adjustment screw. The coarse adjustment connecting plate 4 and the axial adjustment connecting plate 8 are rigidly connected by the radial fine adjustment screw.

[0034] The mounting bracket 1 has a radial feed coarse adjustment limit block 20 for positioning on its side surface.

[0035] The radial fine-tuning locking mechanism is located on the upper surface of the coarse-tuning connecting plate 4 and the axial adjustment connecting plate 8. One end of the radial fine-tuning locking plate 23 in the radial fine-tuning locking mechanism is fixed on the axial adjustment connecting plate 8, and the strip-shaped adjustment hole at the other end is fitted onto the fine-tuning locking screw located on the coarse-tuning connecting plate 4. After the fine-tuning of the axial adjustment connecting plate 8 is completed, it is locked by the fine-tuning locking screw.

[0036] A radial feed fine-tuning scale 19 is provided on the side surface of the mounting bracket 1, and a scale pointer 18 is provided on the surface of the axial adjustment connecting plate 8 above the radial feed fine-tuning scale. During feed, the radial feed amount is controlled by the position of the feed fine-tuning scale pointer 18 on the radial feed fine-tuning scale 19, so as to accurately control the position of the cutter 15.

[0037] A radial coarse adjustment locking plate 22 is provided on one side surface of the coarse adjustment connecting plate 4, and a radial coarse adjustment locking screw is provided on the radial coarse adjustment locking plate. After the coarse adjustment connecting plate 4 is adjusted into place, the radial coarse adjustment locking screw is tightened against the side surface of the mounting bracket 1 to achieve locking and positioning of the coarse adjustment connecting plate.

[0038] The axial adjustment mechanism is located on the upper surface of the axial adjustment connecting plate 8. Three vertical support plates are arranged on the upper surface of the axial adjustment connecting plate 8, one of which is an adjusting screw support plate 27; the other two support plates are guide shaft support plates 17. Each of the three support plates has coaxial through holes for mounting the axial adjustment screw 9 and the guide shaft 10, respectively. The center lines of the through holes on the three support plates are parallel to the axis of the cutter rotation mechanism 14.

[0039] The through hole for mounting the guide shaft is machined with a clamping groove, and the two ends of the clamping groove are located at the 3 o'clock and 9 o'clock positions of each through hole, respectively.

[0040] A bearing 28 is installed in the through hole for mounting the axial adjusting screw 9 and is positioned by a shaft retaining ring 29; one end of the axial adjusting screw is inserted into the bearing.

[0041] The guide shaft 10 is installed in the through holes of the two support plates, and the guide shaft and the through holes are axially slidingly fitted. To prevent the guide shaft from rotating during operation, a guide key 11 is provided on the circumferential surface of the guide shaft. Limit blocks 12 are respectively placed on the upper surface of the two guide shaft support plates 17. When the guide shaft is adjusted to the correct position, the limit blocks are tightened by bolts, thereby axially locking the multi-cover guide shaft 10 and causing the set screw 30 to press against the surface of the guide key.

[0042] The inner end of the axial adjusting screw 9 is threadedly connected to the outer end of the guide shaft 10. The axial adjusting screw is installed in the through hole of the adjusting screw support plate via a bearing 28 and is positioned by a shaft retaining ring 29.

[0044] The cutting blade rotation mechanism uses existing technology.

[0045] The upper surface of the mounting bracket 1 has a first linear guide rail 2 and a second linear guide rail 25. A first slider 3 and a second slider 7 are respectively mounted on the first linear guide rail 2. A third slider 21 and a fourth slider 24 are respectively mounted on the second linear guide rail 25. A coarse adjustment connecting plate 4 is bolted between the upper parts of the first slider 3 and the fourth slider 24. An axial adjustment connecting plate 8 is bolted between the upper parts of the second slider 7 and the third slider 21. A radial fine adjustment mechanism is provided between the upper parts of the coarse adjustment connecting plate 4 and the axial adjustment connecting plate 8 to achieve the purpose of radial fine adjustment of the feed amount of the cutter 15. A radial fine adjustment locking mechanism is also provided on the coarse adjustment connecting plate 4 to achieve the purpose of locking after radial fine adjustment. A radial coarse adjustment locking mechanism is provided on the side of the coarse adjustment connecting plate 4 to lock the movement of the four sliders on the two sets of linear guide rails, thereby locking the radial coarse adjustment cutter. An axial adjustment connecting plate 8 is also provided with an axial adjustment mechanism for adjusting the axial movement of the cutter 15.

[0046] The radial coarse adjustment locking mechanism includes a radial coarse adjustment locking plate 22 that is bolted to the side of the coarse adjustment connecting plate 4. The radial coarse adjustment locking plate 22 is bolted to the side of the mounting bracket 1.

[0047] In this embodiment: the radial fine-tuning mechanism includes a radial fine-tuning fixing seat 6 bolted to the coarse-tuning connecting plate 4 and a radial fine-tuning nut 13 on the axial-tuning connecting plate 8. A radial fine-tuning screw 5 is rotatably mounted on the radial fine-tuning fixing seat 6. The radial fine-tuning nut 13, the radial fine-tuning screw 5, and the radial fine-tuning fixing seat 6 form a threaded fine-tuning mechanism.

[0048] In this embodiment, the radial fine-tuning locking mechanism includes a radial fine-tuning locking plate 23 that is bolted to the coarse-tuning connecting plate 4. The other end of the radial fine-tuning locking plate 23 is fixed to the axial adjustment connecting plate 8 by screws. The radial fine-tuning locking plate 23 is provided with a strip hole, so that when the coarse-tuning connecting plate 4 moves, the bolt used to connect the radial fine-tuning locking plate 23 can slide in the strip hole. When the coarse-tuning connecting plate 4 moves to the appropriate position, the bolt is tightened to lock the radial fine-tuning locking plate 23.

[0049] In this embodiment, the axial adjustment mechanism includes a fixed limiting block 27, a first limiting block 12, and a second limiting block 17 bolted to the axial adjustment connecting plate 8. An axial adjustment screw 9 is rotatably mounted on the fixed limiting block 27. The axial adjustment screw 9 is threadedly connected to a guide shaft 10. A guide key 11 is provided on the guide shaft 10. The end of the guide shaft 10 away from the axial adjustment screw 9 passes through the first limiting block 12 and the second limiting block 17 in sequence and is bolted to a connecting plate 16.

[0050] The axial adjusting screw 9 and the fixed limiting block 27 are rotatably connected by a deep groove ball bearing 28 and a shaft retaining ring 29.

[0051] Both the first limiting block 12 and the second limiting block 17 are threaded with set screws 30, which press against the guide key 11 to lock the cutter for axial adjustment.

[0052] A cutting blade rotation mechanism 14 is bolted to the connecting plate 16. The cutting blade rotation mechanism 14 drives the cutting blade 15 to rotate, thereby achieving the purpose of sliding and cutting the copper foil on the cutting blade roller 26.

[0053] One side of the mounting bracket 1 is connected by a radial feed coarse adjustment limit block 20 via a thread, which achieves the purpose of locking after radial coarse adjustment.

[0054] During operation, the coarse adjustment connecting plate 4 and the axial adjustment connecting plate 8 of the radial coarse adjustment locking mechanism move on the slide rail to adjust the position of the radial coarse adjustment locking mechanism. The mechanism is positioned by the radial feed coarse adjustment limit block 20 and locked by the radial coarse adjustment locking plate 22, so that the radial coarse adjustment locking plate 22 is locked against the mounting support 1, preventing the first slider 3 and the fourth slider 24 from sliding on the mounting support 1.

[0055] Rotating the axial adjustment screw 9 drives the guide shaft 10 to move, which in turn drives the connecting plate 16 to move the cutter 15 to the position of the cutter roller 26, thus completing the axial feed adjustment.

[0056] Adjust the radial fine-tuning nut 13 on the axial adjustment connecting plate 8 to move on the radial fine-tuning screw 5, thereby driving the axial adjustment connecting plate 8 to move, so that the cutter 15 contacts the copper foil on the cutter roller 26, and adjust the fine-tuning feed amount of the cutter 15. During fine-tuning, the position of the first limit block 17 on the radial feed fine-tuning scale 19 can be used to determine the specific position of the feed amount. After fine-tuning, tighten the bolt on the radial fine-tuning locking plate 23 to lock the radial fine-tuning locking plate 23 on the coarse adjustment connecting plate 4 to prevent the displacement of the axial adjustment connecting plate 8 from affecting the copper foil cutting effect.
