Description

Technical Field

[0001] This utility model relates to the field of aluminum foil coating technology, and in particular to a coating apparatus for producing carbon-coated aluminum foil. Background Technology

[0002] An aluminum foil coating apparatus is an industrial device used to uniformly coat the surface of aluminum foil with functional materials. It mainly consists of an unwinding system, a coating head, a drying system, and a rewinding system. Its core function is to form a uniform coating on the aluminum foil through high-precision coating and drying processes. It is widely used in lithium battery electrode manufacturing, packaging materials, and electronic composite materials.

[0003] Existing coating equipment for producing carbon-coated aluminum foil has significant drawbacks. Its coating head is designed to be too large and cumbersome, making disassembly and installation during routine maintenance extremely inconvenient. This structural defect not only increases the difficulty of operation for workers but also prolongs equipment cleaning time, seriously affecting production efficiency. Especially in situations where frequent replacement of coating heads is required for deep cleaning, the large size makes the entire disassembly and assembly process time-consuming and laborious, failing to meet the needs of modern production lines for rapid equipment maintenance.

[0004] Therefore, in view of the problem that the coating head of the existing coating device for producing carbon-coated aluminum foil is large and not easy to disassemble and clean quickly, a new type of coating device for carbon-coated aluminum foil that is smaller and easier to disassemble can be designed. Utility Model Content

[0005] To overcome the problem that the existing coating equipment for producing carbon-coated aluminum foil has a large coating head that is not easy to disassemble and clean quickly.

[0006] The technical solution of this utility model is as follows: a coating device for producing carbon-coated aluminum foil, comprising a fixed frame, elastic claws, and a connecting seat. A unwinding roller is located on the top right side of the fixed frame, and a take-up roller is located on the top left side of the fixed frame. Two support rollers are installed on the top of the fixed frame. A raw material box is placed on the inner bottom surface of the fixed frame. A conveying pipe is connected to the rear side of the raw material box via a pump. A spraying module is connected to the end of the conveying pipe furthest from the raw material box. Support legs are located on the top of the fixed frame between the two support rollers. A transmission assembly is connected to the top of the two support legs. An elastic component is installed at the bottom of the transmission assembly. A mounting plate is connected to the bottom of the elastic component. Five equally spaced elastic claws are installed at the bottom of the mounting plate. A connecting seat is fitted onto the outer side of each elastic claw. Locking blocks are machined on both the left and right sides of the elastic claws. Locking slots are opened on both the left and right sides of the connecting seat corresponding to the locking blocks. The locking blocks and locking slots are matched. A coating head is located at the bottom of the connecting seat.

[0007] Preferably, by setting elastic claws and connecting seats, the connecting seats can be fitted onto the outside of the elastic claws. During fitting, the elastic claws are squeezed inward by the inner wall of the connecting seats and then the connecting seats are pushed upward. The locking blocks on the surface of the elastic claws will gradually approach the locking grooves on the surface of the connecting seats. When the locking blocks move to the position of the locking grooves, the rebound force of the elastic claws can cause the locking blocks to lock into the locking grooves, thereby locking the connecting seats. When it is necessary to disassemble the connecting seats, simply press the locking blocks inward to remove the connecting seats. This enables quick insertion and removal of multiple coating heads, making it convenient for workers to clean the modular coating heads. This solves the problem that the coating heads of existing coating devices for producing carbon-coated aluminum foil are large and inconvenient to disassemble and clean quickly.

[0008] Preferably, the transmission assembly includes a mounting frame and a drive motor; the top of the two legs is connected to the mounting frame, the drive motor is embedded in the rear of the mounting frame, and the output end of the drive motor is connected to a transmission component.

[0009] Preferably, the transmission component includes a lead screw disposed inside the mounting frame, the front end of the lead screw being rotatably connected to the inner front end of the mounting frame, a drive motor being used to drive the lead screw to rotate, and a sliding component being disposed on the outer side of the lead screw.

[0010] Preferably, the sliding member includes a movable block sleeved around the lead screw. The movable block is threadedly engaged with the lead screw. When the lead screw rotates clockwise, it causes the movable block to move forward. When the lead screw rotates counterclockwise, it causes the movable block to move backward. The bottom of the movable block is connected to the top of the elastic component.

[0011] Preferably, the elastic component includes a sleeve, a spring, and a slide rod; the bottom of the movable block is connected to the sleeve, the top of the inside of the sleeve is connected to the spring, the bottom of the spring is mounted on the slide rod, the slide rod is slidably connected to the sleeve, and the bottom of the slide rod is fixed to the top of the mounting plate.

[0012] Preferably, two positioning rods are installed on the top of the mounting plate, and two positioning cylinders are installed on the bottom of the movable block, with the positioning rods slidably connected to the corresponding positioning cylinders.

[0013] Preferably, the left and right sides of the two positioning cylinders are provided with sliding grooves, and the top of the two positioning rods is connected with a baffle. When the positioning rod slides inside the positioning cylinder, it drives the baffle to slide inside the sliding groove.

[0014] The beneficial effects of this utility model are:

[0015] By configuring multiple independently coated heads arranged at equal intervals to replace the traditional integrated large coated roller structure, the maintainability of the equipment is significantly improved. Each coated head can be disassembled and repaired individually, greatly reducing the risk of cross-contamination between different materials. At the same time, the modular structure reduces mechanical wear and extends the overall service life of the equipment. It is particularly suitable for continuous production environments, ensuring the hygiene, safety and stable operation of the production process.

[0016] By incorporating flexible claws and a connecting seat, the coating head can be quickly assembled and disassembled, facilitating daily cleaning and maintenance. The flexible claws provide a stable connection, while easy disassembly requires only simple operation, avoiding the cumbersome steps of traditional fixing methods. This facilitates disassembly and cleaning, prevents residue accumulation, improves equipment lifespan and coating quality, significantly reduces maintenance costs, and enhances operational convenience.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment of a coating device for producing carbon-coated aluminum foil, comprising a fixed frame 1, elastic claws 12, and a connecting seat 13. A unwinding roller 2 is located on the top right side of the fixed frame 1, and a winding roller 3 is located on the top left side of the fixed frame 1. Two support rollers 4 are installed on the top of the fixed frame 1. A raw material box 5 is placed on the inner bottom surface of the fixed frame 1. A conveying pipe 6 is connected to the rear side of the raw material box 5 via a pump. A spraying module 7 is connected to the end of the conveying pipe 6 away from the raw material box 5. Support legs 8 are located on the top of the fixed frame 1 between the two support rollers 4. A transmission assembly is connected to the top of the two support legs 8. An elastic component is installed at the bottom of the transmission assembly. A mounting plate 11 is connected to the bottom of the elastic component. Five equally spaced elastic claws 12 are installed at the bottom of the mounting plate 11. A connecting seat 13 is sleeved on the outer side of each elastic claw 12. Clamping blocks 14 are machined on both the left and right sides of the elastic claw 12. Corresponding to the left and right sides of the connecting seat 13... Each of the locking blocks 14 has a slot 15, which is adapted to the locking block 14. The bottom of the connecting seat 13 is provided with a coating head 16. By adopting the cooperation design of the elastic claw 12 and the connecting seat 13, the connecting seat 13 can be sleeved on the outside of the elastic claw 12. During the assembly process, the inner wall of the connecting seat 13 applies radial pressure to the elastic claw 12, forcing the claw to produce inward elastic deformation. As the connecting seat 13 continues to move axially, the locking block 14 on the surface of the elastic claw 12 gradually aligns with the slot 15 on the connecting seat 13. When the locking block 14 reaches the corresponding position of the slot 15, the elastic claw 12 drives the locking block 14 to pop out radially by its own restoring force, forming an interlock with the slot 15, thus completing the fixation of the connecting seat 13. When disassembling, the locking block 14 can be released by manually applying radial pressure to disengage it from the slot 15. This design realizes the quick insertion and removal function of the coating head 16 module, which is convenient for operators to maintain and clean the modular coating head 16.

[0025] Please see Figure 2 and Figure 5In this embodiment, the transmission assembly includes a mounting frame 91 and a drive motor 92; the top of the two support legs 8 is connected to the mounting frame 91, and the drive motor 92 is embedded in the rear side of the mounting frame 91. The output end of the drive motor 92 is connected to a transmission component. The mounting frame 91 is used to position and install the drive motor 92. The transmission component includes a lead screw 93 disposed inside the mounting frame 91. The front end of the lead screw 93 is rotatably connected to the front end of the inner side of the mounting frame 91. The drive motor 92 drives the lead screw 93 to rotate. A sliding component is disposed on the outer side of the lead screw 93. A lead screw 93 is provided, and a drive motor 92 can drive the lead screw 93 to rotate during operation. The sliding component includes a movable block 94 sleeved around the lead screw 93. The movable block 94 is threadedly engaged with the lead screw 93. When the lead screw 93 rotates clockwise, it drives the movable block 94 to move forward. When the lead screw 93 rotates counterclockwise, it drives the movable block 94 to move backward. The bottom of the movable block 94 is connected to the top of the elastic component. By setting the movable block 94, when the lead screw 93 rotates, it can drive the movable block 94, which is threadedly engaged with it, to slide back and forth, thereby driving the multiple coating heads 16 on the lower side to move synchronously and realize the coating function.

[0026] Please see Figures 2-5 In this embodiment, the elastic component includes a sleeve 101, a spring 102, and a slide rod 103. The bottom of the moving block 94 is connected to the sleeve 101, the top of the sleeve 101 is connected to the spring 102, and the bottom of the spring 102 is mounted on the slide rod 103. The slide rod 103 is slidably connected to the sleeve 101, and the bottom of the slide rod 103 is fixed to the top of the mounting plate 11. By setting the spring 102, when the coating head 16 contacts the aluminum foil, the aluminum foil has a certain thickness, which will squeeze the coating head 16, thereby causing the spring 102 to contract, so that the overall height of the mounting plate 11 is raised, thereby achieving the purpose of flexibly adapting to aluminum foils of different thicknesses. Two slide rods are mounted on the top of the mounting plate 11. The positioning rod 17 and the bottom of the moving block 94 are equipped with two positioning cylinders 18. The positioning rod 17 is slidably connected to the corresponding positioning cylinder 18. By setting the positioning rod 17 and the positioning cylinder 18, the mounting plate 11 can drive the positioning rod 17 to slide synchronously inside the positioning cylinder 18 when it is raised and lowered, thereby improving the stability of the lifting and lowering of the mounting rod. The left and right sides of the two positioning cylinders 18 are provided with sliding grooves 20, and the top of the two positioning rods 17 is connected with baffles 19. When the positioning rod 17 slides inside the positioning cylinder 18, it drives the baffles 19 to slide inside the sliding grooves 20. By setting the sliding grooves 20 and the baffles 19, the sliding distance of the positioning rod 17 can be limited, preventing the positioning rod 17 from slipping out of the inside of the positioning cylinder 18.

[0027] During operation, the aluminum foil is sleeved on the unwinding roller 2, with one end passing over the upper side of the two support rollers 4 and connecting to the take-up roller 3. The take-up roller 3 and the unwinding roller 2 rotate, driving the aluminum foil to move. The pump of the raw material box 5 is started, and the coating inside is transferred to the spraying module 7 through the feed pipe 6 without dead angles. The coating is sprayed onto the surface of the aluminum foil through the nozzle of the spraying module 7. Then, the drive motor 92 is started, driving the lead screw 93 to rotate. The lead screw 93 drives the moving block 94 that is threaded with it to move back and forth, so that the coating head 16 can evenly coat the coating on the surface of the aluminum foil. After coating is completed, the locking blocks 14 on both sides of the elastic claw 12 can be pressed to make the elastic claw 12 retract inward, releasing the positioning of the connecting seat 13, thereby realizing the quick disassembly of the coating head 16 for easy cleaning.

[0028] Through the above steps, by setting up the elastic claw 12 and the connecting seat 13, during assembly, the connecting seat 13 is axially fitted into the elastic claw 12, and the inner wall of the connecting seat 13 contacts the elastic claw 12, forcing the elastic claw 12 to contract radially. As it continues to advance, the locking block 14 on the elastic claw 12 gradually aligns with the locking groove 15 of the connecting seat 13. When the locking block 14 reaches the locking groove 15, the elastic claw 12 quickly unfolds due to its own springback characteristics, so that the locking block 14 is embedded in the locking groove 15, forming a mechanical interlock, thereby firmly fixing the connecting seat 13. During disassembly, simply press the locking block 14 manually to disengage it from the locking groove 15 to unlock it. This design enables the quick assembly and disassembly of the coating head 16 module, making it convenient for maintenance personnel to clean or replace the modular coating head 16. This solves the problem that the coating head 16 of the existing coating device for producing carbon-coated aluminum foil is too large and not easy to disassemble and clean quickly.
