Description

Technical Field

[0001] This utility model relates to the field of aluminum foil production technology, specifically to an aluminum foil production rolling device. Background Technology

[0002] Aluminum foil, as an industrial manufacturing raw and auxiliary material, has the advantages of moisture-proof, airtight, light-blocking, wear-resistant, aroma-preserving, non-toxic and odorless. It is widely used in packaging protection, daily necessities, construction and other fields. In the production process of aluminum foil, it needs to be rolled. After the rolling operation, oil stains will be attached to the surface of the aluminum foil.

[0003] According to a public announcement of an aluminum foil production rolling device (Announcement No.: CN220837238U), the above application includes a frame, the inner walls of both sides of the frame are respectively fixed to the corresponding ends of the transmission roller, and mounting plates are installed on both ends of one side of the frame. A side plate is installed on the top of one set of mounting plates, and a motor is installed on one side of the side plate. The output end of the motor is connected to a rotating roller, and a cleaning rod is fixedly sleeved on the outer surface of the rotating roller.

[0004] However, although the aforementioned cleaning rods and brush rollers can play a certain role in removing oil during the aluminum foil calendering process, as the running time increases, their surfaces will continuously absorb and accumulate oil. When the oil gradually reaches saturation, the cleaning element's own cleaning ability will significantly decrease, resulting in the inability to effectively remove residual oil from the aluminum foil surface. More seriously, the dirty oil already attached to the cleaning rods and brush rollers may be transferred back to the aluminum foil surface during the roller rotation process, causing not only secondary pollution but also affecting the cleanliness of the aluminum foil surface and product quality. In view of this, we propose an aluminum foil production calendering device. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum foil production rolling apparatus to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum foil production rolling apparatus, comprising a rolling mill, wherein aluminum foil sheets are disposed inside the rolling mill, a frame is fixedly connected to the side wall of the rolling mill, and a cleaning assembly is disposed on the side wall of the frame, the cleaning assembly comprising: A spray frame, wherein spray holes are provided on the bottom surface of the interior of the spray frame and spray holes are provided on the top surface of the interior of the spray frame; A drive module, the drive module including a motor, the output end of the motor being fixedly connected to a mounting bracket, and a hinge rod being hinged to the bottom of the mounting bracket; Scraper 1 is fixedly connected to the inner wall of the frame, and scraper 2 is fixedly connected to the inner wall of the frame; The mounting groove has an absorption roller slidably connected to its inner wall.

[0007] Preferably, the spray frame is slidably connected to the inner wall of the frame body, the spray frame is connected to an external liquid supply device, and a collection box is inserted into the inner wall of the frame body. A volatile cleaning agent, such as isopropyl alcohol, is sprayed onto both sides of the aluminum foil through the spray frame.

[0008] Preferably, a flat plate is fixedly connected to the side wall of the frame, the flat plate is fixedly connected to the motor, and the end face of the hinge rod is sleeved with the spray frame.

[0009] Preferably, the first scraper is arranged in a V-shape, and the second scraper is arranged in a straight line. The first scraper scrapes off the volatile cleaning agent on the top of the aluminum foil. A collection box is slidably connected to the inner wall of the frame.

[0010] Preferably, the mounting groove is fixedly connected to the inner wall of the frame, and the number of absorption rollers is set in two sets, which are arranged symmetrically.

[0012] Preferably, the number of drive modules is set to two sets, one set of drive modules has a hinge rod rotatably connected to the spray frame, and the other set of drive modules has a hinge rod rotatably connected to the air blowing frame.

[0013] Compared with the prior art, this utility model provides an aluminum foil production rolling apparatus, which has the following beneficial effects:

[0014] 1. This aluminum foil production calendering device, through its cleaning components, sprays volatile cleaning agents onto both sides of the aluminum foil. The lateral reciprocating motion ensures that the spray trajectory covers the entire width of the aluminum foil, guaranteeing a more uniform distribution of cleaning agents on both sides and improving the cleaning effect. This allows oil stains to disperse and dissolve in the solvent environment. The V-shaped scraper effectively collects and guides the cleaning liquid on the upper surface to both sides, preventing large-area accumulation of liquid on the aluminum foil surface. The liquid easily flows away along the V-shaped edge, making it less likely to leave liquid droplets on the aluminum foil. The upper and lower scrapers can scrape off the cleaning agents and oil stains on the upper and lower surfaces of the aluminum foil respectively. The contact adsorption of the absorption roller removes the thin solvent residue and further removes residual cleaning agents, ensuring a drier and cleaner aluminum foil surface, protecting the surface quality of the aluminum foil, and preventing water stains from forming on the aluminum foil surface when residual solvent evaporates unevenly, thus keeping the aluminum foil surface smooth.

[0015] 2. This aluminum foil production rolling device uses hot air to quickly evaporate residual liquid through the air blowing frame, achieving more thorough drying, significantly shortening drying time, increasing production line speed, and ensuring uniform hot air blowing to ensure a clean and bright aluminum foil surface, which is beneficial for subsequent processing such as lamination and coating. The air blowing frame is hinged to the drive module, which can realize transverse reciprocating blowing, making the hot air coverage more uniform and avoiding local overheating or drying dead corners.

[0022] like Figures 1-5 As shown, this utility model provides a technical solution: an aluminum foil production calendering device, including a calendering equipment 1, an aluminum foil sheet 2 is arranged inside the calendering equipment 1, a frame 3 is fixedly connected to the side wall of the calendering equipment 1, and a cleaning component 4 is arranged on the side wall of the frame 3. The cleaning component 4 includes a spray frame 401, a drive module 402, a first scraper 403, a second scraper 404, a mounting groove 405, and an absorption roller 406.

[0023] In one embodiment of this utility model, a spray hole is provided on the bottom surface of the spray rack 401 and a spray hole is provided on the top surface of the spray rack 401. The spray rack 401 is slidably connected to the inner wall of the frame 3. The spray rack 401 is connected to an external liquid supply device. A collection box 5 is inserted into the inner wall of the frame 3. A volatile cleaning agent, such as isopropyl alcohol, is sprayed onto both sides of the aluminum foil sheet 2 through the spray rack 401.

[0024] The drive module 402 includes a motor 4021. The output end of the motor 4021 is fixedly connected to a mounting bracket 4022. The bottom of the mounting bracket 4022 is hinged to a hinge rod 4023. A plate is fixedly connected to the side wall of the frame 3. The plate is fixedly connected to the motor 4021. The end face of the hinge rod 4023 is sleeved with the spray frame 401.

[0025] Scraper 1 403 is fixedly connected to the inner wall of the frame 3. Scraper 2 404 is fixedly connected to the inner wall of the frame 3. Scraper 1 403 is set in a V-shape, and scraper 2 404 is set in a straight line. Scraper 1 403 scrapes off the volatile cleaning agent on the top of the aluminum foil sheet 2.

[0026] The mounting groove 405 is fixedly connected to the inner wall of the frame 3. The inner wall of the mounting groove 405 is slidably connected to the absorption roller 406. There are two sets of absorption rollers 406, and the two sets of absorption rollers 406 are arranged symmetrically.

[0027] A volatile cleaning agent, such as isopropanol, is sprayed onto both sides of the aluminum foil sheet 2 using a spray rack 401. The organic portion of isopropanol interacts with the hydrocarbon chains in the oil, causing the oil to disperse and dissolve in its solvent environment. Then, scraper 403 removes the volatile cleaning agent from the top of the aluminum foil sheet 2. Scraper 403 is V-shaped, which forms a confluence device in the middle, effectively collecting and guiding the cleaning liquid on the upper surface to both sides, preventing the liquid from accumulating on the aluminum foil surface. The liquid easily flows away along the edge of the V-shape, making it less likely to leave liquid droplets on the aluminum foil, thus improving cleaning uniformity. Scraper 404 removes the cleaning agent from the bottom surface of the aluminum foil sheet 2. Scraper 404 is straight, and the two scrapers can remove the cleaning agent from the upper and lower surfaces of the aluminum foil sheet 2 respectively, ensuring that the cleaning agent and oil are removed evenly, improving drying and cleaning efficiency.

[0028] Then, the aluminum foil sheet 2 passes between two sets of absorption rollers 406. The absorption rollers 406 are wrapped with highly absorbent materials, such as non-woven fabric or sponge layer. Through contact adsorption, the slight solvent residue is removed, and the residual cleaning agent is further removed, ensuring that the aluminum foil surface is drier and cleaner, protecting the surface quality of the aluminum foil, and preventing water stains from forming on the aluminum foil surface when the residual solvent evaporates unevenly, thus keeping the aluminum foil surface smooth.

[0029] Motor 4021 drives mounting bracket 4022 to rotate, which in turn drives hinge rod 4023 to move. Since the direction of movement of spray frame 401 is restricted by frame body 3, when the end of mounting bracket 4022 away from motor 4021 rotates to the side closer to frame body 3, hinge rod 4023 pushes spray frame 401 to move away from motor 4021. When the end of mounting bracket 4022 away from motor 4021 rotates to the side away from frame body 3, hinge rod 4023 pulls spray frame 401 to move closer to motor 4021, realizing the lateral reciprocating motion of spray frame 401. The lateral reciprocating motion can make the spray trajectory cover the entire width of aluminum foil, ensuring that the cleaning agent is more evenly distributed on both sides, improving the cleaning effect. The solvent spray point changes continuously, which can increase the relative disturbance between the cleaning agent and the aluminum foil surface, and enhance the peeling and dissolving effect of oil stains.

[0030] In addition, an air blowing frame 8 is slidably connected to the inner wall of the frame 3, and a hot air blower 6 is fixedly connected to the side wall of the frame 3. A hose 7 is fixedly connected to the output end of the hot air blower 6, and the hose 7 is fixedly connected to the air blowing frame 8. Two sets of drive modules 402 are provided. The hinge rod 4023 in one set of drive modules 402 is rotatably connected to the spray frame 401, and the hinge rod 4023 in the other set of drive modules 402 is rotatably connected to the air blowing frame 8. With the hot air blower 6 working in conjunction with the air blowing frame 8, the residual liquid can be quickly evaporated by hot air, achieving more thorough drying, significantly shortening the drying time, and increasing the production line speed. The uniform blowing of hot air can ensure that the aluminum foil surface is clean and bright, which is beneficial for subsequent processing such as lamination and coating. The air blowing frame 8 is hinged to the drive module 402, which can realize horizontal reciprocating blowing, making the hot air coverage more uniform and avoiding local overheating or drying dead corners.

[0031] In this invention, during use, a volatile cleaning agent is sprayed onto both sides of the aluminum foil sheet 2 through the spray frame 401, causing the oil stains to disperse and dissolve in its solvent environment. The upper and lower scrapers can scrape off the cleaning agent from the upper and lower surfaces of the aluminum foil sheet 2 respectively, ensuring that the cleaning agent and oil stains are removed evenly. The aluminum foil sheet 2 passes between two sets of absorption rollers 406, which are wrapped with highly absorbent materials such as non-woven fabric or sponge layer. Through contact adsorption, a thin layer of solvent residue is removed, and residual cleaning agent is further removed, ensuring that the aluminum foil surface is drier and cleaner.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
