Description

Technical Field

[0001] The invention relates to the field of electrolytic copper foil, in particular to a non-turnover type edge trimming device for an electrolytic copper foil machine. Background Art

[0002] Electrolytic copper foil is one of the basic materials of the electronics industry. It is mainly used to make the conductive material of printed circuit boards (PCBs) - copper clad laminates (CCL) and the main raw material for lithium battery cathodes. During the production process of electrolytic copper foil, the copper foil produced by the cathode roller is prone to oxidation and thickening at the edge of the cathode roller and burrs. When winding, the copper foil is prone to warping, resulting in loose rolls and wrinkles, which affects the quality of the foil roll. Therefore, a trimming device is required to trim the original foil produced.

[0003] The existing trimming devices of the raw foil machine are mainly rotary trimming devices. When the trimming device is feeding and retracting, it is necessary to manually flip the heavy cutter, cutter shaft, cutter bracket, coupling, motor and shield device and other trimming parts. The parts generally weigh 3kg-10gk. For the operator of the raw foil machine, flipping the cutter parts is a heavy physical job, and the flipping causes the cutter blade to be exposed, which creates a safety hazard. The cutter depth cannot be quantified during the cutting process of the cutter blade, which will cause serious wear of the cutter and the cutter groove, resulting in a decrease in the life of the cutter and frequent tearing of the copper foil, which ultimately affects the copper foil production.

[0004] The invention with Chinese patent publication number CN111086039A discloses an online copper foil trimming device for a foil production machine, which requires manual turning of the cutter, increasing the manual work intensity and causing safety hazards. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art that the trimming device is bulky and cannot be quantified, resulting in a reduced life of the cutter and frequent edge tearing of the copper foil, the present invention proposes a non-flipping trimming device for an electrolytic copper foil production machine.

[0006] The present invention includes a mounting support, a radial fine-tuning mechanism, a radial fine-tuning locking mechanism, a radial coarse-tuning locking screw, an axial adjustment mechanism, a cutter rotating mechanism and a cutter. The upper surface of the mounting support is provided with a first linear guide and a second linear guide parallel to each other, and the coarse-adjusting connecting plate and the axial adjustment connecting plate of the radial coarse-adjusting locking mechanism are respectively installed on the first linear guide and the second linear guide through a first slider, a second slider, a third slider and a fourth slider. A radial fine-tuning fixing seat is provided on the upper surface of the coarse-adjusting connecting plate, and a radial fine-tuning nut is provided on the upper surface of the axial adjustment connecting plate; one end of the radial fine-tuning screw is placed in the 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-adjusting 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 surfaces of the coarse-adjusting connecting plate and the axial-adjusting connecting plate, and one end of the radial fine-tuning locking plate in the radial fine-tuning locking mechanism is fixed on the axial-adjusting connecting plate, and the strip-shaped adjustment hole at the other end is sleeved on the fine-tuning locking screw located on the coarse-adjusting connecting plate.

[0007] A radial feed coarse adjustment limit block is provided on the side surface of the mounting support.

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

[0009] A radial coarse adjustment locking plate is provided on one side surface of the coarse adjustment connecting plate, and a radial coarse adjustment locking screw is provided on the radial coarse adjustment locking plate. When the coarse adjustment connecting plate is adjusted into place, the radial coarse adjustment locking screw is pressed against the side surface of the mounting support to realize 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, one end of which is the adjustment screw support plate; the other two support plates are guide shaft support plates. There are coaxial through holes on the three support plates, which are used to install the axial adjustment screw and the guide shaft respectively. The center lines of the through holes on the three support plates are parallel to the axis of the cutter rotating mechanism.

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

[0012] The guide shaft is installed in the through holes on the two support plates, and the guide shaft and the through holes are axially slidably matched; in order to prevent the guide shaft from rotating during operation, a guide key is provided on the circumferential surface of the guide shaft. There are limit blocks on the upper surfaces of the two guide shaft support plates respectively; when the guide shaft is adjusted into place, the limit blocks are tightened by bolts, thereby realizing the axial locking of the multi-cover guide shaft and making the top screw 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 surface of the guide shaft, and the other end is sleeved on the cutter shaft of the cutter rotating mechanism through a bearing.

[0014] The inner end of the axial adjustment screw is fixedly connected to the outer end of the guide shaft through a thread. The axial adjustment screw is installed in the through hole of the adjustment screw support plate through a bearing and is positioned by a shaft retaining ring;

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention loosens the coarse adjustment locking mechanism, manually moves all the components on the linear guide rail to the position of the limit block and locks them; loosens the radial fine adjustment locking mechanism, rotates the radial feed fine adjustment screw to make the cutter close to the foil surface, rotates the axial fine adjustment screw assembly to align the cutter blade with the cutter roller groove, starts the cutter rotation button, and the cutter starts to rotate; rotates the radial feed fine adjustment screw, observes that the scale pointer points to the specified position of the radial fine adjustment scale, and the cutter will also feed to the foil cutting position to start edge cutting.

[0017] The present invention can realize the cutter alignment and feed functions by rotating axial and radial screws, avoiding the cumbersome work of flipping the cutter component when the flip cutter is feeding, saving the operator's physical strength, and also avoiding the safety risk of the cutter blade facing the operator when flipping. In view of the wear of the cutter blade caused by the artificial feeding depth, a scale feed is designed to achieve the standardization of the cutter feeding. When the present invention is used, the operator saves physical strength, avoids safety risks, and prevents blade wear caused by different feeding depths, saving labor costs and the cost of using the cutter, and improving production efficiency.
