Technical Field
[0001] This utility model belongs to the field of stainless steel coil processing technology, specifically relating to an automatic film coating device for wide stainless steel coils. Background Technology
[0002] Stainless steel coils are classified into austenitic, ferritic, martensitic, and duplex (ferritic-austenitic) stainless steel cold-rolled coils and stainless steel hot-rolled coils.
[0003] Chinese patent application number 2024202626413 discloses a film-coating packaging mechanism, including a base plate, two first electric telescopic rods, two second electric telescopic rods, a film, and a motor. Support plates are fixedly mounted on the front and rear sides of one side of the upper surface of the base plate. Rotating columns are rotatably mounted on opposite sides of the two support plates. Sliding sleeves are slidably fitted onto the front and rear sides of the outer ends of the two rotating columns. In this invention, the position of the sliding sleeves on the rotating columns accommodates steel coils of different sizes. A hanger lifts the steel coil and places it above the sliding sleeves. The film is pulled onto the steel coil, and the motor drives the connecting column to rotate, thereby rotating the steel coil and wrapping the film around its outer end. Activating the first telescopic rods pulls the slider, which in turn drives the arc plate to push the film upwards, thus wrapping the edges of the steel coil more completely.
[0004] The aforementioned patent does not have a cutting function. After the steel coil is coated, it cannot automatically cut the film. At the same time, the original device cannot squeeze the film attached to the steel coil to make the film adhere better to the steel coil, resulting in low coating quality. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0021] Please see Figure 1-4The present invention provides the following technical solution: an automatic film coating device for wide stainless steel coils, including a base plate 1, two side plates 9 fixed on one side of the upper end of the base plate 1, a film roller 8 rotatably connected between the two side plates 9, two support plates 5 fixed on the other side of the upper end of the base plate 1, rotating columns 6 arranged on both sides between the two support plates 5, limit sleeves 7 arranged on both sides of the surface of the rotating columns 6, a driving mechanism 4 arranged at the front end of one support plate 5, an extrusion assembly 3 arranged at the upper end of the support plate 5, and a cutting assembly 2 arranged at the middle position of the upper end of the base plate 1.
[0022] Specifically, the cutting assembly 2 includes a fixed frame 21, an electric push rod 22, a moving plate 23, a cutter 24, a strip seat 25, a cutter groove 26, and a limiting assembly 27. The fixed frame 21 is fixed at the middle position of the upper end of the base plate 1. The electric push rod 22 is installed at the middle position of the upper end of the fixed frame 21. The moving plate 23 is provided at the output end of the electric push rod 22. The cutter 24 is fixed at the lower end of the moving plate 23. The strip seat 25 is fixed inside the lower side of the fixed frame 21. The upper end of the strip seat 25 is provided with a cutter groove 26 corresponding to the cutter 24. The limiting assembly 27 is provided at both ends of the fixed frame 21.
[0023] By adopting the above technical solution, the film is passed through the fixed frame 21. After the film coating work is completed, the electric push rod 22 is turned on. The electric push rod 22 pushes the moving plate 23 and the cutter 24 to move downward. The cutter 24 enters the knife groove 26 of the strip seat 25 to cut the film. By setting the cutting component 2, the film can be automatically cut, which improves the automation of the device and reduces the amount of manual work.
[0024] Specifically, the limiting component 27 includes a horizontal plate 271, a limiting roller 272, a rotating shaft 273, and a limiting disc 274. Two horizontal plates 271 are fixed at both ends of the fixed frame 21, and two limiting rollers 272 are arranged between the two horizontal plates 271. The limiting rollers 272 are connected to the horizontal plates 271 through the rotating shaft 273, and the limiting discs 274 are fixed on both sides of the surface of the limiting rollers 272.
[0025] By adopting the above technical solution, the film passes through the two limiting rollers 272 at both ends of the fixing frame 21. The limiting rollers 272 can rotate on the horizontal plate 271 via the rotating shaft 273. At the same time, limiting disks 274 are set on both sides of the surface of the limiting rollers 272 to prevent the film from being displaced on the limiting rollers 272. By setting the limiting component 27, the film can be limited to prevent the film from scratching the strip seat 25 or the cutter 24.
[0026] In this embodiment, when using the automatic coating device for wide stainless steel coils, the device is installed in a suitable position, and the steel coil is placed on two rotating columns 6. The limiting sleeves 7 on the rotating columns 6 limit the steel coil. Then, one end of the film on the film roller 8 is fixed to the steel coil. The driving mechanism 4 drives the two rotating columns 6 to rotate, which in turn drives the steel coil to rotate. The rotation of the steel coil causes the film to adhere to the steel coil, achieving the coating effect. By setting the cutting component 2, the film is passed through the fixing frame 21. After the coating work is completed, the electric push rod 22 is activated. The electric push rod 22 pushes the moving plate 23 and the cutter 24 downward. The cutter 24 enters the cutter groove 26 of the strip seat 25 to cut the film. The film can be automatically cut by setting the cutting component 2, which improves the automation of the device and reduces the amount of manual work. The film passes through the two limiting rollers 272 at both ends of the fixed frame 21 by setting the limiting component 272. The limiting rollers 272 can rotate on the horizontal plate 271 by rotating shaft 273. At the same time, the limiting disks 274 are set on both sides of the surface of the limiting rollers 272 to prevent the film from being displaced on the limiting rollers 272. The film can be limited by setting the limiting component 27 to prevent the film from scratching the strip seat 25 or the cutter 24. Example 2
[0027] The difference between this embodiment and embodiment 1 is that the extrusion assembly 3 includes a folding plate 31, a top plate 32, a slide bar 33, a moving frame 34, an extrusion roller 35, a spring 36, and a support assembly 37. The upper end of the support plate 5 is fixed with a folding plate 31, the upper end of the folding plate 31 is provided with a top plate 32, the upper end of the top plate 32 is fixed with a handle, the lower ends of the top plate 32 are fixed with slide bars 33 on both sides, the upper end of the folding plate 31 is provided with sliding holes corresponding to the slide bars 33, the lower end of the slide bars 33 is fixed with a moving frame 34, the moving frame 34 is rotatably connected with an extrusion roller 35, the moving frame 34 and the folding plate 31 are connected with a spring 36 on the outside of the slide bars 33, and the upper end of the folding plate 31 is provided with a support assembly 37.
[0028] By adopting the above technical solution, pulling the handle on the top plate 32 moves the top plate 32, which in turn moves the slide rod 33 in the folding plate 31. The movement of the slide rod 33 moves the moving frame 34 upward, while the spring 36 is compressed. Then, the steel coil is placed on the rotating column 6, and after fixing one end of the film to the steel coil, the top plate 32 is released. The spring 36 extends and pushes the moving frame 34 back to its original position. The extrusion roller 35 in the moving frame 34 extrudes the steel coil. When the steel coil rotates for film coating, the extrusion roller 35 rotates in the moving frame 34. The extrusion roller 35 can extrude the film attached to the steel coil, thereby making the film and the steel coil adhere more closely and improving the coating quality.
[0029] Specifically, the support component 37 includes a rotating rod 371, a rotating plate 372, a groove 373, and an arc-shaped edge 374. The rotating rod 371 is rotatably connected to one side of the upper end of the folding plate 31, and the rotating plate 372 is fixed to the upper end of the rotating rod 371. A groove 373 corresponding to the rotating plate 372 is opened on one side of the lower end of the top plate 32, and arc-shaped edges 374 are provided at both ends of the groove 373.
[0030] By adopting the above technical solution, after the top plate 32 is moved upward by placing the steel coil, the rotating plate 372 is turned. The rotating plate 372 rotates on the folding plate 31 through the rotating rod 371, so that the rotating plate 372 faces the top plate 32. One end of the rotating plate 372 enters the groove 373 on the lower side of the top plate 32. The rotating plate 372 can support the top plate 32. At the same time, arc-shaped edges 374 are set at both ends of the groove 373 to facilitate the rotating plate 372 entering the groove 373. By setting the support component 37, the top plate 32 can be supported and limited, which facilitates the placement of the steel coil.
[0031] Specifically, the rotating rod 371 and the folding plate 31 are connected by damping rotation, and the extrusion roller 35 and the moving frame 34 are connected by a pivot pin.
[0032] By adopting the above technical solution, the rotating rod 371 is less likely to rotate on the folding plate 31, and the extrusion roller 35 can rotate in the moving frame 34.
[0033] In this embodiment, by setting the extrusion assembly 3, pulling the handle on the top plate 32 moves the top plate 32, causing the slide rod 33 to slide in the folding plate 31. The movement of the slide rod 33 moves the moving frame 34 upward, while the spring 36 is compressed. Then, the steel coil is placed on the rotating column 6, and after fixing one end of the film to the steel coil, the top plate 32 is released. The spring 36 extends and pushes the moving frame 34 back to its original position. The extrusion roller 35 in the moving frame 34 extrudes the steel coil. When the steel coil rotates for film coating, the extrusion roller 35 rotates in the moving frame 34, and the extrusion roller 35 can extrude the film attached to the steel coil. To improve the adhesion between the film and the steel coil and enhance the coating quality, a support assembly 37 is provided. After the top plate 32 is moved upward by placing the steel coil, the rotating plate 372 is turned. The rotating plate 372 rotates on the folding plate 31 via the rotating rod 371, so that the rotating plate 372 faces the top plate 32. One end of the rotating plate 372 enters the groove 373 on the lower side of the top plate 32. The rotating plate 372 can support the top plate 32. At the same time, arc-shaped edges 374 are provided at both ends of the groove 373 to facilitate the entry of the rotating plate 372 into the groove 373. The support assembly 37 can support and limit the top plate 32, which is convenient for placing the steel coil.
[0034] In this utility model, the electric push rod 22 is a prior art technology, and the selected model is FTG50.
[0035] The structure and working principle of the bottom plate 1, driving mechanism 4, support plate 5, rotating column 6, limiting sleeve 7, film roller 8 and side plate 9 of this utility model have been disclosed in a film-coating packaging mechanism disclosed in Chinese patent application No. 2024202626413. Its working principle is to place the steel coil on two rotating columns 6, and the limiting sleeve 7 on the rotating column 6 limits the steel coil. Then, one end of the film on the film roller 8 is fixed to the steel coil. The driving mechanism 4 drives the two rotating columns 6 to rotate. The rotation of the two rotating columns 6 drives the steel coil to rotate. The rotation of the steel coil causes the film to adhere to the steel coil, thus achieving the effect of film coating.
[0036] The working principle and usage process of this utility model: When using the automatic coating device for wide stainless steel coils, the device is installed in a suitable position, and the steel coil is placed on two rotating columns 6. The limiting sleeves 7 on the rotating columns 6 limit the steel coil. Then, one end of the film on the film roller 8 is fixed to the steel coil. The driving mechanism 4 drives the two rotating columns 6 to rotate, and the rotation of the two rotating columns 6 drives the steel coil to rotate. The rotation of the steel coil causes the film to adhere to the steel coil, achieving the coating effect. By setting the cutting component 2, the film is passed through the fixing frame 21. After the coating work is completed, the electric push rod 22 is activated. The electric push rod 22 pushes the moving plate 23 and the cutter... The blade 24 moves downwards and enters the blade groove 26 of the strip holder 25 to cut the film. The cutting assembly 2 automatically cuts the film, improving automation and reducing manual labor. The limiting assembly 27 guides the film through the two limiting rollers 272 at both ends of the fixed frame 21. The limiting rollers 272 rotate on the horizontal plate 271 via the rotating shaft 273. Simultaneously, limiting discs 274 are provided on both sides of the limiting rollers 272 to prevent displacement of the film. The limiting assembly 27 limits the film, preventing it from rubbing against the strip holder 25. Alternatively, the cutter 24, through the extrusion assembly 3, pulls the handle on the top plate 32 to move the top plate 32. The top plate 32 drives the slide rod 33 to slide in the folding plate 31. The movement of the slide rod 33 causes the moving frame 34 to move upward, while the spring 36 is compressed. Then, the steel coil is placed on the rotating column 6, and after fixing one end of the film to the steel coil, the top plate 32 is released. The spring 36 extends and pushes the moving frame 34 to return to its original position. The extrusion roller 35 in the moving frame 34 extrudes the steel coil. When the steel coil rotates for film coating, the extrusion roller 35 rotates in the moving frame 34. The extrusion roller 35 can extrude the film attached to the steel coil, thereby... To improve the adhesion between the film and the steel coil and enhance the coating quality, a support assembly 37 is provided. After the top plate 32 is moved upward by placing the steel coil, the rotating plate 372 is turned. The rotating plate 372 rotates on the folding plate 31 via the rotating rod 371, so that the rotating plate 372 faces the top plate 32. One end of the rotating plate 372 enters the groove 373 on the lower side of the top plate 32. The rotating plate 372 can support the top plate 32. At the same time, arc-shaped edges 374 are provided at both ends of the groove 373 to facilitate the entry of the rotating plate 372 into the groove 373. The support assembly 37 can support and limit the top plate 32, which is convenient for placing the steel coil.
