Description

TECHNICAL FIELD

[0001] The utility model relates to a blade processing equipment technical field, concretely relates to a slitting blade processing equipment. BACKGROUND

[0002] The capacitor slitting equipment is an important mechanical equipment in capacitor production, which is mainly used for accurately slitting large roll capacitor materials (such as aluminum foil, metallized film, etc.) according to the specified size. These slitted materials will be further used to make the internal electrode or dielectric part of the capacitor. The main slitting process of the slitting blade processing equipment currently often adopts the wave slitting, that is, using a specially processed cutter to press the extremely thin circular blade into a regular undulating shape similar to a wave, so as to slit the capacitor film into different specifications of strip film rolls with sinusoidal curved edges.

[0003] The existing wave slitting process needs to use a blade holder and a blade cover to clamp the blade, and then press the blade into a wave shape radiating from the center to the edge of the blade. Then, the film is slit by the cutter with the wave-shaped appearance, so as to obtain the required curved edge shape. Since the blade holder and the blade cover are relatively thick, and the chamfer at the wave valley cannot be accurately controlled during processing, when the chamfer at the wave valley is too large, it will cause poor wave forming or failure to form during pressing the blade, resulting in unqualified curved edges during slitting. At the same time, since the blade tips are severely worn after processing multiple blade holders, the cutter needs to be frequently processed under the premise of ensuring the yield, resulting in high maintenance frequency and high maintenance cost.

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model.

[0032] As Figures 1-8 shown, in one embodiment, a slitting blade machining equipment comprises: a knife holder pressing piece 1, wherein the knife holder pressing piece 1 comprises a first pressing piece 11 and a second pressing piece 12, both of which are oppositely arranged to form a clamping structure, firmly clamping the blade in the middle, which can effectively improve the stability and durability of the knife holder and optimize its use performance when the film is slitting. Specifically, the knife holder pressing piece 1 is processed using aluminum alloy or titanium alloy material, has excellent strength and lightweight characteristics, can reduce the weight of the knife holder while ensuring high performance: the aluminum alloy material has better machining precision and corrosion resistance, while the titanium alloy has better wear resistance and corrosion resistance, suitable for high-load and high-frequency working environment.

[0033] Furthermore, the first pressing plate 11 and the second pressing plate 12 are provided with extrusion sections 13 facing each other, and the extrusion section 13 includes crests 131 and troughs 132. The crests 131 of the first pressing plate 11 and the troughs 132 of the second pressing plate 12 are closely matched in their outer contours, forming a precise matching structure that enables uniform pressure application during the extrusion process. Specifically, the crests 131 and troughs 132 are equidistantly distributed along the circumference of the first pressing plate 11, and equidistantly distributed along the circumference of the second pressing plate 12, ensuring pressure uniformity and precision during blade cutting.

[0034] Through the above technical solution, the integrated blade holder composed of the first pressing sheet 11 and the second pressing sheet 12 simplifies the structure of the corrugated blade holder, making the overall thickness of the corrugated blade holder thinner. When performing film slitting, it can slitting film rolls of smaller specifications, thereby improving the applicability and production efficiency of the blade holder and adapting to a wider range of film slitting production.

[0035] like Figures 1-8 As shown, in this embodiment, the extrusion section 13 has a transition groove 14, which solves the problems of uneven cutting and hooks on the film edge caused by excessive chamfering at the transition of the trough 132 in the prior art. Specifically, the transition groove 14 is formed radially inward at the transition of the trough 132 of the first pressing sheet 11 and the second pressing sheet 12. The depth of the transition groove 14 is 40-60% of the height of the extrusion section 13 and 30-40% of the width of the extrusion section 13.

[0036] Through the above technical solution, the transition groove 14 makes the pressure distribution between the first pressing plate 11 and the second pressing plate 12 more uniform, especially the pressure transmission at the transition of the trough 132 becomes smoother. This fine structural adjustment ensures that the wavy edge of the film no longer has hooks or damage during the film slitting process, thus guaranteeing the quality and yield of the slitting film. In addition, the precision requirements of the processing blade tip are reduced, which can effectively reduce the wear rate of the blade in actual production. The service life of the blade is significantly extended, reducing the need for frequent blade replacement, thereby reducing downtime and production line maintenance frequency, and thus improving the overall operating efficiency of the film production line, reducing maintenance costs and losses caused by production interruptions.

[0037] like Figures 1-8 As shown, in this embodiment, the first pressure plate 11 has multiple sets of fixing holes 15 through it, and fixing screws 2 are installed in the fixing holes 15, so that the first pressure plate 11 and the second pressure plate 12 can be firmly connected together by fixing screws 2. Specifically, the fixing holes 15 are provided in 6-10 sets at equal intervals to ensure that the fixing screws 2 can evenly distribute the pressure during the assembly process, thereby improving the stability and firmness of the overall structure.

[0038] Further, the first pressing sheet 11 and the second pressing sheet 12 are provided with fixing grooves 16 on the opposite end faces, and precisely processed spacers 3 are installed in the fixing grooves 16, which help to precisely align the position of the blade and effectively avoid the problems of uneven cutting or damage caused by displacement or instability of the blade during cutting. Specifically, the material of the spacer 3 is SUS304 stainless steel, which has good corrosion resistance, wear resistance and high strength, and can maintain stable performance for a long time without deformation or wear, ensuring that the spacer 3 can still work stably for a long time under high pressure, high temperature or other harsh working conditions, thereby prolonging the service life of the blade.

[0039] Working principle: The upper and lower pressing sheets of the blade holder pressing sheet 1 sandwich the blade in the middle, position the blade with the spacer 3, and then use the fixing screw 2 to fix and compress the upper and lower pressing sheets, so that the sandwiched blade is pressed into a sine wave-shaped blade that meets the requirements according to the processing shape of the pressing sheet end face.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
