With the development of the industry, the requirements for the uniformity and thickness accuracy of optical films are constantly increasing.

[0003] Traditional coating technology has many limitations. For example, roller coating is easily affected by roller flatness and pressure distribution, and lacks precision when coating thin optical films. Spray coating also has problems such as poor coating uniformity, and during the coating process, excess parts will remain on the surface of the finished product, which is time-consuming and laborious to remove individually. Summary of the invention

[0004] The purpose of the present invention is to provide an extrusion type optical film coating production device, which has the advantages of uniform coating, flattening the material and removing the excess part during the manufacturing process of the optical film, preventing agglomeration during coating, secondary mixing of the material and preventing the material from hanging on the wall.

[0005] The above technical purpose of the present invention is achieved through the following technical scheme: an extrusion type optical film coating production device, comprising a coating device base frame, an outer shell and a scraping component, the scraping component is arranged on the upper surface of the coating device base frame, molds are bonded on both sides of the upper surface of the coating device base frame, a coating component is arranged on the surface of the scraping component, and the outer shell is welded to the surface of the coating component.

[0006] By adopting the above technical scheme, the outer shell is used to protect the coating component, the coating component is used for secondary mixing of materials, uniform discharge of materials and prevention of material hanging on the wall, and can automatically scrape off residual materials at the discharge port, and the leveling component is used to level the surface of the optical film and remove excess material on the top and both sides.

[0007] The present invention is further configured as follows: the scraping assembly includes a limit plate, a first cleaning plate and a second gear, the two groups of limit plates are respectively welded to the two sides of the upper surface of the coating device chassis, the two groups of the first cleaning plates are respectively welded to the middle of the two lateral sides of the two groups of limit plates, the second cleaning plates are welded to the middle of the surfaces of the two groups of limit plates, and the two groups of limit plates are slidably connected with connecting rods inside.

[0008] With the above technical solution, the limiting plate is used to limit the movement of the connecting rod, and the first cleaning plate and the second cleaning plate are both used to clean the excess material.

[0009] The present invention is further configured as follows: a side scraper is welded to one end of the two groups of connecting rods, the side scraper is located on the inner side of the limiting plate and parallel to the first cleaning plate, a first spring pull rod is welded to the other side of the two groups of side scrapers, a rectangular frame is welded to the other ends of the two groups of the first spring pull rods, and a fixing rod is welded to the upper ends of the two groups of connecting rods.

[0010] By adopting the above technical solution, when the rectangular frame moves, it will drive the connecting rod to move inside the limiting plate, so that the connecting rod follows the path of the limiting plate and reciprocates using the first spring pull rod.

[0011] The present invention is further configured as follows: rotating columns are rotatably connected on both sides of the rectangular frame surface, two groups of the second gears are respectively welded to the two groups of rotating column surfaces, upper scrapers are welded to the two groups of rotating column surfaces, a second tooth plate is welded to one end of the fixed rod, and the second tooth plate is meshingly connected to the second gear.

[0012] By adopting the above technical solution, the fixed rod will drive the second tooth plate to move while following the movement of the connecting rod, and the second tooth plate will drive the second gear to rotate, thereby causing the second gear to drive the upper scraper to rotate using the rotating column.

[0013] The present invention is further configured as follows: the coating assembly includes a motor, a screw, a spring push rod and a material holding barrel, the motor is bolted to one end of the outer shell surface, the screw is fixedly connected to the motor output end through a coupling, vertical plates are welded on both sides of the upper end of the outer shell, two groups of spring push rods are respectively welded to one side of the surface of the two groups of vertical plates, and the piston ends of the two groups of spring push rods are jointly welded with a first tooth plate.

[0014] Using the above technical solution, the motor and the lead screw are used to provide power for the operation of the coating assembly, and the design of the spring push rod prevents the gear from getting stuck with the first tooth plate when it moves in the reverse direction. Because when the motor runs in the reverse direction, it will drive the material barrel to move in the reverse direction. At this time, the gear will not rotate, because the bevel block will block the push rod from rotating, and then block the gear from rotating, so the first tooth plate will retract using the spring push rod.

[0018] By adopting the above technical solution, the holes on the surface of the mounting plate are used for conveying materials, and the push rod is used for squeezing the inclined block to drive the squeezing plate to move downward.

[0019] The present invention is further configured as follows: a discharge shell is welded to the lower end of the material containing barrel, two groups of second spring pull rods are welded to both sides of the top inside the discharge shell, extrusion plates are welded to the piston ends of the four groups of the second spring pull rods, four groups of inclined blocks are fixedly connected to the middle of the upper end of the extrusion plate, a limiting tube is fixedly connected to the middle of the upper end of the extrusion plate, movable columns are welded to both sides of the lower surface of the discharge shell, third cleaning plates are rotatably connected to the surfaces of the two groups of movable columns, ball head structures are welded to the surfaces of the two groups of the third cleaning plates and the two groups of connecting rods, and mounting rods are welded to the two corresponding groups of ball head structures.

[0020] By adopting the above technical solution, when the inclined block is squeezed, it will drive the squeezing plate to use the second spring pull rod to continuously squeeze downward inside the discharge shell to facilitate discharge. The third cleaning plate is used to clean the residual material at the discharge end of the discharge shell.

[0021] In summary, the present invention has the following beneficial effects: When in use, the coating component is started to drive the scraping component to run. The coating component needs to be filled before starting. During startup, the material can be mixed twice, and uniform coating can be achieved and the material can be prevented from hanging on the wall inside the coating component. When the coating component is moving for coating, it will drive the scraping component to run synchronously. The scraping component can scrape the surface of the optical film and remove excess material on the upper end and both sides. The removed excess material can also be automatically cleaned from the removal structure, and when the excess material on the cleaning structure is removed, the coating component will be driven to synchronously remove the residual material from the coating outlet, which can avoid sagging and accumulation, thereby affecting uniform discharge, thereby achieving the effect of improving the use efficiency of the coating device.

[0026] Brief description of the use process: When in use, the coating component 3 is started to drive the scraping component 5 to move. The coating component 3 needs to be filled before starting. When starting, the materials can be mixed, and uniform coating can be achieved and the materials can be prevented from hanging on the wall inside the coating component 3. When the coating component 3 is moving for coating, it will drive the scraping component 5 to run synchronously. The scraping component 5 can scrape the surface of the optical film and remove excess material on the upper end and both sides. The removed excess material can also be automatically cleaned from the removal structure, and when the excess material on the cleaning structure is removed, the coating component 3 will be driven to synchronously remove the residual material from the coating discharge port, which can avoid sagging and accumulation, thereby affecting uniform discharge. The inside of the mold 4 is used for the production of optical films, which can improve the use efficiency of the coating device.

[0027] Embodiment 2: Based on Example 1, Figure 3 and Figure 4 The scraping assembly 5 includes a limit plate 510, a first cleaning plate 511 and a second gear 508. The two sets of limit plates 510 are respectively welded to the two sides of the upper surface of the coating device chassis 1. The two sets of first cleaning plates 511 are respectively welded to the middle of the two horizontal sides of the two sets of limit plates 510. The middle of the surface of the two sets of limit plates 510 is welded with a second cleaning plate 512. The inside of the two sets of limit plates 510 is slidably connected with a connecting rod 504; one end of the two sets of connecting rods 504 is welded with a side scraper 503, which is located on the inner side of the limit plate 510 and is level with the first cleaning plate 511. The first spring pull rod 502 is welded to the other side of the two groups of side scrapers 503, and the other ends of the two groups of first spring pull rods 502 are welded with a rectangular frame 501, and the upper ends of the two groups of connecting rods 504 are welded with a fixed rod 505; both sides of the surface of the rectangular frame 501 are rotatably connected with rotating columns 507, and two groups of second gears 508 are respectively welded to the surfaces of the two groups of rotating columns 507, and the surfaces of the two groups of rotating columns 507 are welded with upper scrapers 509, and one end of the fixed rod 505 is welded with a second tooth plate 506, and the second tooth plate 506 is meshingly connected with the second gear 508.

[0028] A brief description of the use process: When the connecting rod 504 is pulled to move inside the limit plate 510, the connecting rod 504 will automatically telescope and move according to the path of the limit plate 510. When the two sets of connecting rods 504 extend outward, since the connecting rod 504, the fixing rod 505 and the second tooth plate 506 are all fixedly connected, the second tooth plate 506 will drive the second gear 508 to rotate. Since the rotating column 507 is rotatably connected to the rectangular frame 501, and the second gear 508 is fixedly connected to the rotating column 507, and the rotating column 507 is fixedly connected to the upper scraper 509, the upper scraper 509 will follow the second gear. The wheel 508 rotates, and after the rotation is completed, the excess material on the surface of the upper scraper 509 will be scraped off by the second cleaning plate 512, and the side scraper 503 will also be driven to move synchronously, and the excess material on the surface of the side scraper 503 will be cleaned and removed by the first cleaning plate 511. The first spring pull rod 502 is used to pull the upper scraper 509 and the side scraper 503 to retract and reset, and the upper scraper 509 is used to remove the excess material on the upper end of the optical film to achieve a smoothing effect, and the side scraper 503 is used to remove the excess material on the side of the optical film, thereby achieving the effect of improving the production quality of the optical film.

[0029] Embodiment 3: Based on Example 2, Figure 3 , Figure 5 , Figure 6 and Figure 7The coating assembly 3 includes a motor 301, a screw rod 302, a spring push rod 304 and a material holding barrel 307. The motor 301 is bolted to one end of the surface of the shell 2, and the screw rod 302 is fixedly connected to the output end of the motor 301 through a coupling. Vertical plates 303 are welded on both sides of the upper end of the shell 2. Two groups of spring push rods 304 are respectively welded to one side of the surface of the two groups of vertical plates 303, and the piston ends of the two groups of spring push rods 304 are welded with a first tooth plate 305; the material holding barrel 307 is threadedly connected to the surface of the screw rod 302, and the material holding barrel 307 and the shell 2 are slidingly connected. A support plate 308 is welded on the upper end of the inner wall of the material holding barrel 307, and a spiral blade 309 is rotatably connected inside the support plate 308. Both sides of the surface of the spiral blade 309 are welded with impurity removal plates 310; a first gear 306 is welded at one end of the spiral blade 309, and the first gear 306 is connected to the first gear 306. A tooth plate 305 is meshedly connected, a mounting plate 314 is welded to the other end of the spiral blade 309, and three groups of push rods 315 are welded to the lower surface of the mounting plate 314; a discharge shell 313 is welded to the lower end of the material holding barrel 307, and two groups of second spring pull rods 312 are welded to both sides of the top of the discharge shell 313, and the piston ends of the four groups of second spring pull rods 312 are welded to an extrusion plate 311, and four groups of inclined blocks 317 are fixedly connected to the middle part of the upper end of the extrusion plate 311, and a limiting tube 316 is fixedly connected to the middle part of the upper end of the extrusion plate 311, and movable columns 319 are welded to both sides of the lower surface of the discharge shell 313, and the surfaces of the two groups of movable columns 319 are rotatably connected to the third cleaning plates 318, and the two groups of third cleaning plates 318 and the surfaces of the two groups of connecting rods 504 are welded with ball head structures 320, and the corresponding two groups of ball head structures 320 are commonly welded with mounting rods 321.

[0030] Brief description of the use process: The spiral blade 309 will mix the material to a certain extent when it is running. When the motor 301 is running, the screw rod 302 will be used to drive the barrel 307 to move. When the barrel 307 is in use, a certain amount of the material that has been initially mixed will be added. During the movement of the barrel 307, the tooth plate 305 will be used to drive the gear 306 to rotate, thereby driving the spiral blade 309 to rotate, so that the spiral blade 309 regularly transports the material downward. The impurity removal plate 310 is used to scrape off the material remaining on the inner wall of the barrel 307 to prevent it from hanging on the wall. When the material is transported to one end of the spiral blade 309, it will pass through the holes on the surface of the mounting plate 314 and the limiting tube 316 into the inside of the discharge shell 313, and these materials are located below the extrusion plate 311. The limiting tube 316 is used to prevent the material from entering above the extrusion plate 311, and the mounting plate 314 is close to the limiting tube 316 and the discharge shell. The top of the shell 313 will not leak material. When the mounting plate 314 rotates with the spiral blade 309, it will drive the push rod 315 to rotate synchronously and squeeze the inclined block 317, so that the inclined block 317 drives the extrusion plate 311 to use the second spring push rod 304 to continuously and repeatedly operate, thereby squeezing the material inside the discharge shell 313. When the material is not squeezed, it will not be discharged. Therefore, a certain amount of material will accumulate inside the discharge shell 313 before discharging, so as to achieve uniform discharging, and when the coating component 3 moves, the mounting rod 321 will be used to drive the scraping component 5 to move, because the use of the two sets of ball head structures 320 will not cause jamming, and the mounting rod 321 will follow the movement of the connecting rod 504 to drive the third cleaning plate 318 to rotate, and scrape off the residual material at the discharge end of the discharge shell 313 to prevent accumulation, thereby affecting the uniform discharge, thereby achieving the effect of facilitating uniform material distribution.
