Description

Technical Field

[0001] This application relates to the field of slitting equipment technology, specifically a slitting equipment for composite aluminum foil production. Background Technology

[0002] The slitting device is used to cut various types of films (mainly copper foil, aluminum foil, OPP, PET and other aluminized, zinc-plated, aluminized zinc alloy foil films, electrode insulating diaphragms and polypropylene films for power capacitors) into the required widths according to the design requirements of capacitor manufacturing, and then roll them into film rolls that meet certain technical standards.

[0003] An existing patent (publication number: CN222042140U) discloses a high-precision unwinding and slitting machine for copper and aluminum foil, including an operating table. A support frame one is located on one side of the top of the operating table, and a placement roller is mounted on the support frame one. A support frame two is located on the side of the operating table away from the support frame one, and a take-up roller is mounted on the support frame two. One side of the take-up roller extends out of the support frame two and connects to a motor drive end. A support frame three is located at the top of the operating table, between the support frame one and the support frame two, and the support frame three contains several equally spaced blade fixing frames. Beneficial effects: By setting a spacing adjustment component, the spacing of multiple sets of blades can be adjusted simultaneously, greatly saving blade adjustment time and improving adjustment efficiency. By setting a tension adjustment plate, cylinder, and pressure roller, the material tension can be adjusted to make it more stable, facilitating blade slitting.

[0004] The aforementioned prior art describes a slitting device that requires adjustment of the blade spacing according to requirements during use. However, most existing adjustment methods can only adjust each blade individually, resulting in low efficiency. To further improve the convenience of blade adjustment and avoid excessive debris accumulation on the blade surface that could affect cutting accuracy, a composite aluminum foil production slitting device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a slitting device for composite aluminum foil production, which employs a gear and rack linkage mechanism with a worm gear and an integrated dust collection component, effectively improving upon the deficiencies of existing technologies.

[0006] To achieve the above objectives, this application provides the following technical solution: a slitting device for composite aluminum foil production, comprising a substrate, a slitting assembly, a dust extraction assembly, a feeding assembly, and a winding assembly. The slitting assembly includes a fixed frame fixedly connected to the upper surface of the substrate. A rotating rod is rotatably sleeved on the inner wall of the fixed frame. A worm gear is fixedly connected to one end of the rotating rod, and a first planar gear and a second planar gear are fixedly connected to the other end of the rotating rod. A worm gear meshing with the worm gear is installed on one side of the fixed frame, and a servo motor is fixedly connected to one side of the fixed frame. The output shaft end of the servo motor is fixedly connected to the rotating shaft end of the worm gear.

[0007] A transverse guide rail is fixedly connected to the other side of the fixed frame. A fixed block is fixedly connected to the middle section of the transverse guide rail. A second slider and a first slider are slidably connected to both sides of the transverse guide rail. A second rack is fixedly connected to the back of each of the two second sliders. A first rack is fixedly connected to the back of each of the two first sliders. Both of the two second racks mesh with a second planar gear. Both of the two first racks mesh with a first planar gear. A slitting blade is installed at the bottom end of each fixed block, second slider, and first slider.

[0008] The above solution uses the meshing transmission of the worm gear and worm to drive the rotating rod, which in turn drives the first and second planar gears to move the first and second racks in opposite directions. This causes the first and second sliders to slide synchronously along the transverse guide rail, enabling one-click adjustment of the spacing between the multi-component cutting blades. This significantly improves efficiency compared to traditional lead screw mechanisms. Furthermore, the dust collection component can adsorb cutting debris in real time, preventing excessive debris accumulation on the cutting blade surface from affecting cutting efficiency. The overall structure is simplified and the precision is controllable, effectively addressing the shortcomings of existing technologies.

[0009] Furthermore, the vacuuming assembly includes a vacuum cleaner body fixedly connected to the bottom surface of the substrate and a support plate disposed above the substrate. The output end of the vacuum cleaner body penetrates the substrate and is equipped with a corrugated pipe, which is located above the substrate.

[0010] The above solution allows the vacuum cleaner to flexibly adjust the path for picking up debris by using a corrugated tube, making it easy to work with corresponding components.

[0011] Furthermore, a vacuum head is embedded in the bottom of the tray, the top of the corrugated pipe is connected to the bottom of the vacuum head, and four electric push rods are installed on the upper surface of the substrate, with the output ends of the four electric push rods fixedly connected to the bottom surface of the tray.

[0012] With the above solution, the height of the electric push rod can be adjusted so that the vacuum head is always close to the working surface of the slitting knife, which enhances the efficiency of picking up debris and reduces the probability of debris accumulating on the surface of the slitting knife. In addition, the corrugated pipe can be used to ensure the stable suction of the vacuum head when the pallet moves up and down.

[0013] Furthermore, two guide rollers are installed on the upper surface of the tray, the fixing frame is located between the two guide rollers, and a maintenance cover is installed on one side of the vacuum cleaner body by bolts.

[0014] The above solution guides the aluminum foil transport path, ensuring the material remains straight during the slitting process and reducing offset or wrinkles. The maintenance cover is fixed with bolts, making it easy to open quickly and clean the inside of the vacuum cleaner or replace the filter.

[0015] Furthermore, the unloading assembly and the winding assembly are respectively mounted on both sides of the upper surface of the substrate, and the tray is located between the unloading assembly and the winding assembly.

[0016] With the above solution, the feeding and winding components are symmetrically distributed on both sides of the substrate, and together with the slitting and dust collection components in the middle, a continuous processing flow is formed, which improves the slitting efficiency.

[0017] Furthermore, a controller is fixedly connected to one side of the fixing frame, and the electrical components inside the slitting assembly, the dust suction assembly, and the winding assembly are all electrically connected to the controller.

[0018] Through the above scheme, the controller centrally controls the drive units of the servo motor, electric push rod and winding assembly, realizing coordinated adjustment of slitting speed, blade spacing and dust collection intensity, ensuring consistency of processing parameters and production stability.

[0019] Furthermore, support columns are fixedly connected to the four corners of the bottom surface of the substrate.

[0020] The above solution provides stable support for the substrate, preventing a decrease in cutting accuracy due to vibration during equipment operation.

[0021] Furthermore, storage drawers are installed on both sides of the bottom surface of the substrate.

[0022] The above solution allows for the storage drawers to hold spare slitting blades, cleaning tools, and maintenance parts, enabling centralized management of tools and consumables, reducing clutter on-site, and improving operational convenience.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This composite aluminum foil production slitting device drives a rotating rod through the meshing transmission of a worm gear and a worm shaft, which in turn drives a first planar gear and a second planar gear to move the first rack and the second rack in opposite directions. This causes the first slider and the second slider to slide synchronously along the transverse guide rail, enabling one-button adjustment of the spacing between multiple slitting blades. The efficiency is significantly improved compared to traditional screw mechanisms. In the dust collection component, the dust collection head is connected to the dust collector body through a corrugated pipe. It works with an electric push rod to adjust the height of the tray and collect slitting debris in real time, preventing excessive debris accumulation on the surface of the slitting blades from affecting the slitting efficiency. The guide roller ensures that the aluminum foil is transported straight and avoids deviation. Therefore, the overall structure of this application is simplified and the precision is controllable, effectively improving the shortcomings of the prior art. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 3 and Figure 5 This embodiment of a composite aluminum foil production slitting device includes a substrate 1, a slitting assembly 2, a dust extraction assembly 3, a feeding assembly 4, and a winding assembly 5. The slitting assembly 2 includes a fixing frame 201 fixedly connected to the upper surface of the substrate 1. A rotating rod 202 is rotatably sleeved on the inner wall of the fixing frame 201. A worm gear 203 is fixedly connected to one end of the rotating rod 202, and a first planar gear 204 and a second planar gear 205 are fixedly connected to the other end of the rotating rod 202. A worm 206 meshing with the worm gear 203 is installed on one side of the fixing frame 201. A servo motor 213 is fixedly connected to one side of the fixing frame 201. The output shaft end is fixedly connected to the rotating shaft end of the worm 206. When the servo motor 213 starts, it drives the worm 206 to rotate. The rotation of the worm 206 causes the worm wheel 203 to rotate. When the worm wheel 203 rotates, it drives the first planar gear 204 and the second planar gear 205 to rotate through the rotating rod 202. The self-locking effect produced by the combination of the worm wheel 203 and the worm 206 can effectively prevent the first planar gear 204 and the second planar gear 205 from rotating randomly. In addition, using the servo motor 213 as a power source has higher precision and convenience compared to manual rotation, making it more practical.

[0034] Please see Figure 2 , Figure 3 and Figure 5 A transverse guide rail 209 is fixedly connected to the other side of the fixing frame 201. A fixing block 210 is fixedly connected to the middle section of the transverse guide rail 209. Second sliders 211 and first sliders 212 are slidably connected to both sides of the transverse guide rail 209. Second racks 208 are fixedly connected to the back of each of the two second sliders 211, and first racks 207 are fixedly connected to the back of each of the two first sliders 212. Both second racks 208 mesh with second planar gears 205, and both first racks 207 mesh with first planar gears 204. The components mesh with each other. Each fixed block 210, second slider 211, and first slider 212 has a slitting blade 214 installed at its bottom. When the first planar gear 204 and the second planar gear 205 rotate, the two first racks 207 and the two second racks 208 will drive the two second sliders 211 and the two first sliders 212 to move along both sides of the transverse guide rail 209. However, the fixed block 210 remains stationary. This allows for synchronous adjustment of the spacing between the multiple slitting blades 214, making it more convenient and practical.

[0035] Please see Figure 1 , Figure 2 and Figure 4The vacuuming assembly 3 includes a vacuum cleaner body 301 fixedly connected to the bottom surface of the substrate 1 and a tray 305 disposed above the substrate 1. The output end of the vacuum cleaner body 301 penetrates the substrate 1 and is equipped with a corrugated pipe 302. The corrugated pipe 302 is located above the substrate 1. The corrugated pipe 302 allows the vacuum cleaner body 301 to flexibly adjust the path for sucking up debris, facilitating its use with corresponding components. A vacuum head 303 is embedded in the bottom of the tray 305. The top end of the corrugated pipe 302 is connected to the bottom of the vacuum head 303. Four electric push rods 304 are mounted on the upper surface of the substrate 1. The output ends of the four electric push rods 304 are all fixedly connected to the bottom surface of the tray 305. The electric push rods 304 can adjust the height of the tray 305, allowing... The suction head 303 is always close to the working surface of the slitting blade 214, enhancing the efficiency of debris extraction and reducing the probability of debris accumulating on the surface of the slitting blade 214. When the tray 305 moves up and down, the corrugated pipe 302 can ensure the stable suction operation of the suction head 303. Two guide rollers 306 are installed on the upper surface of the tray 305, and the fixing frame 201 is located between the two guide rollers 306. A maintenance cover 307 is bolted to one side of the vacuum cleaner body 301. The guide rollers 306 can guide the aluminum foil transmission path, ensuring that the material remains straight during the slitting process and reducing deviation or wrinkles. The maintenance cover 307 is fixed by bolts, which facilitates quick opening and cleaning or filter replacement inside the vacuum cleaner body 301.

[0036] Please see Figure 1 , Figure 2 and Figure 5 The feeding assembly 4 and the winding assembly 5 are respectively installed on both sides of the upper surface of the substrate 1, and the pallet 305 is located between the feeding assembly 4 and the winding assembly 5. The feeding assembly 4 and the winding assembly 5 are symmetrically distributed on both sides of the substrate 1. Together with the slitting assembly 2 and the dust collection assembly 3 in the middle, they form a continuous processing flow line to improve slitting efficiency. A controller 6 is fixedly connected to one side of the fixing frame 201. The electrical components inside the slitting assembly 2, the dust collection assembly 3 and the winding assembly 5 are all electrically connected to the controller 6. The controller 6 centrally controls the servo motor 213 and the electric push rod 304. The drive unit of the winding assembly 5 enables coordinated adjustment of slitting speed, blade spacing, and dust suction intensity, ensuring consistency of processing parameters and production stability. Support columns 7 are fixedly connected to the four corners of the bottom surface of the substrate 1, providing stable support for the substrate 1 and preventing the slitting accuracy from decreasing due to vibration during equipment operation. Storage drawers 8 are installed on both sides of the bottom surface of the substrate 1. The storage drawers 8 are used to store spare slitting blades 214, cleaning tools, and maintenance accessories, realizing centralized management of tools and consumables, reducing on-site material clutter, and improving operational convenience.

[0037] In this embodiment, a slitting device for composite aluminum foil production drives a rotating rod 202 through the meshing transmission of a worm gear 203 and a worm 206. This drives a first planar gear 204 and a second planar gear 205, causing the first rack 207 and the second rack 208 to move in opposite directions. This allows the first slider 212 and the second slider 211 to slide synchronously along the transverse guide rail 209, enabling one-button adjustment of the spacing between the multi-component cutting blades 214. This significantly improves efficiency compared to traditional lead screw mechanisms. In the dust collection assembly 3, the dust collection head 303 is connected to the vacuum cleaner body 301 through a corrugated pipe 302. It works with an electric push rod 304 to adjust the height of the tray 305, adsorbing slitting debris in real time and preventing excessive debris accumulation on the surface of the cutting blades 214, which would affect slitting efficiency. The guide roller 306 ensures that the aluminum foil is transported straight and avoids deviation. Therefore, the overall structure of this application is simplified and the precision is controllable, effectively improving the shortcomings of the prior art.

[0038] The working principle of the above embodiment is as follows: When the slitting device for composite aluminum foil production is working, the rolled composite aluminum foil is unrolled through the feeding assembly 4 and guided into the slitting area by the guide roller 306. In the slitting assembly 2, the servo motor 213 drives the worm gear 206 to rotate, which in turn drives the worm wheel 203 meshing with it to rotate. The worm wheel 203 drives the first planar gear 204 and the second planar gear 205 to rotate synchronously through the rotating rod 202. The first planar gear 204 meshes with the first rack 207, and the second planar gear 205 meshes with the second rack 208. The two sets of racks move in opposite directions, pushing the first slider 212 and the second slider 211 to slide synchronously along the transverse guide rail 209, thereby adjusting the spacing of the slitting blades 214 on the second slider 211 and the first slider 212 on both sides of the fixed block 210, and realizing the precise synchronous adjustment of the spacing of multiple blades. After adjustment, the slitting blade 214 cuts the aluminum foil. In the dust collection assembly 3, the vacuum cleaner body 301 is connected to the vacuum head 303 through the corrugated pipe 302. The electric push rod 304 adjusts the height of the support plate 305 according to the instructions of the controller 6, so that the vacuum head 303 is always close to the cutting surface of the slitting blade 214 and absorbs the generated aluminum foil debris in real time. The guide roller 306 ensures that the aluminum foil transmission path is straight and avoids material deviation or wrinkles. The slitting aluminum foil narrow strip is wound into a standard film roll by the winding assembly 5. The controller 6 centrally controls the speed of the servo motor 213, the lifting range of the electric push rod 304 and the traction speed of the winding assembly 5 to ensure the coordination of slitting parameters and tension control. The whole set of equipment achieves efficient, high-precision and low-maintenance composite aluminum foil slitting processing through the integration of mechanical transmission, automatic control and cleaning functions.
