Description

Technical Field

[0001] This utility model relates to the field of coating device technology, specifically to an antistatic film coating device with a rotating mechanism. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. This machine coats a roll of substrate with a layer of adhesive, paint, or ink with a specific function, and then dries and rewinds it. Coating machines are widely used in current coating production processes. Existing coating methods mainly include scraping coating, which uses PVC paste to coat a cloth base to make artificial leather; casting coating, which uses cast film to coat paper; extrusion coating, which uses extruded flat film to coat a substrate; and brush coating, which uses paint to evenly brush a coating onto a substrate. In addition, there are roller coating, spray coating, and powder coating. In the coating process, existing coating machines may encounter a large amount of dirt, dust, plastic particles, crystals, and static electricity-attracted lines on the sheet, which can affect the quality of subsequent processes and easily lead to substandard quality. Coating machines also lack cleaning measures after the sheet has been processed.

[0003] A search revealed a utility model patent with publication number CN218531517U, which discloses a film coating machine, including a worktable. Two connecting blocks are fixedly installed at both ends of the upper wall of the worktable. A feeding roller is movably installed on one connecting block via a bearing, and a receiving roller is movably installed on the other connecting block via a bearing. A drive motor for driving the receiving roller to rotate is fixedly installed on the side wall of the other connecting block away from the receiving roller.

[0004] The aforementioned patent merely uses two cleaning rollers that rotate as the film moves forward during the coating process to wipe the outer surface of the film, thus preventing impurities adsorbed on the film from affecting the quality of subsequent processes and causing quality defects. However, it cannot adequately clean the coating that easily adheres to the cleaning rollers. If not cleaned for a long time, the adsorbed coating can affect the coating effect. Furthermore, the cleaning blades cannot be detached individually, requiring the entire cleaning assembly to be replaced. This makes it less practical and does not facilitate improving the quality of the film.

[0005] Therefore, it is necessary to invent an antistatic film coating device with a rotating mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an antistatic film coating device with a rotating mechanism. By having the receiving edge and scraper blade adhere to the outer wall of the coating roller, excess coating material on the roller is scraped off. The material flows into a collection box guided by the receiving edge and scraper blade, thus achieving coating collection. This eliminates the need for manual cleaning of the coating roller, preventing excess coating material from affecting the coating effect. The scraper blade is positioned by inserting a positioning rod into a positioning hole, facilitating easy removal and replacement of damaged scraper blades. This addresses the problems of existing technologies that cannot adequately clean coating material easily adhering to the cleaning roller, which can affect the coating effect if not cleaned for a long time. Furthermore, the cleaning blades cannot be detached individually, requiring replacement of the entire cleaning assembly, resulting in low practicality and hindering the improvement of film quality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an antistatic film coating device with a rotating mechanism, comprising a processing table and a material leveling device. A feeding roller, a cleaning device, a material leveling device, and a receiving roller are respectively installed on the top of the processing table.

A scraping blade is movably engaged on the limit plate. A positioning rod is symmetrically fixed to the bottom of the scraping blade. A positioning hole is symmetrically opened inside the limit plate. The positioning hole matches the positioning rod.

[0008] Preferably, the side of the fixed base is hinged with a retaining ring, the end of the retaining ring is provided with a movable groove, the inside of the movable groove is rotatably connected to an operating block, the side of the operating block is fixedly connected to the movable groove by a spring, the end of the operating block is fixedly connected to a fixing block, the side of the fixed base is provided with a groove, the inside of the groove is provided with a fixing groove, the groove matches the operating block, and the fixing groove matches the fixing block.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-7The diagram shows an antistatic film coating apparatus with a rotating mechanism, comprising a processing table 1 and a material leveling device 4. A feeding roller 2, a cleaning device 3, a material leveling device 4, and a receiving roller 5 are respectively mounted on the top of the processing table 1. The material leveling device 4 includes mounting frames 6, which are fixedly connected to the processing table 1. Two mounting frames 6 are provided, symmetrically distributed about the central axis of the processing table 1. Fixing seats 7 are symmetrically fixed to the inner sides of each mounting frame 6. Positioning grooves 8 are provided on the sides of adjacent fixing seats 7. A coating roller 9 is movably engaged between the fixing seats 7 on the inner sides of the two mounting frames 6. Connecting posts 10 are rotatably connected to both ends of the coating roller 9, and the connecting posts 10 match the positioning grooves 8. Two collection boxes 20 are movably engaged between the two mounting frames 6. A receiving edge 21 is fixedly connected to the top. A limiting plate 22 is slidably installed inside the collection box 20. A limiting groove 23 is symmetrically opened inside the collection box 20. The limiting groove 23 matches the limiting plate 22. The bottom of the limiting plate 22 is fixedly connected to the limiting groove 23 by a spring 24. A scraper 25 is movably engaged on the limiting plate 22. A positioning rod 26 is symmetrically fixed to the bottom of the scraper 25. A positioning hole 27 is symmetrically opened inside the limiting plate 22. The positioning hole 27 matches the positioning rod 26. Since the limiting plate 22 is slidably connected to the limiting groove 23 by the spring 24, the scraper 25 will remain in contact with the surface of the coating roller 9 when the film passes between the two coating rollers 9. It can adapt to the movement of the coating roller 9 and play a certain buffering role, improving the cleaning effect of the surface coating without damaging the film.

[0028] A retaining ring 11 is hinged to the side of the fixed base 7. A movable groove 12 is provided at the end of the retaining ring 11. An operating block 13 is rotatably connected inside the movable groove 12. The side of the operating block 13 is fixedly connected to the movable groove 12 by a spring 14. A fixing block 15 is fixedly connected to the end of the operating block 13. A groove 16 is provided on the side of the fixed base 7. A fixing groove 17 is provided on the inner side of the groove 16. The groove 16 matches the operating block 13, and the fixing groove 17 matches the fixing block 15. When the fixing block 15 and the fixing groove 17 are engaged, the retaining ring 11 is spliced ​​with the fixed base 7. The retaining ring 11 is used to press and fix the connecting column 10, which facilitates the subsequent replacement of the coating roller 9.

[0029] A pressure plate 19 is fixedly connected to the inner side of the retaining ring 11 by a spring 18. The pressure plate 19 cooperates with the connecting post 10. Since the pressure plate 19 is connected to the retaining ring 11 by the spring 18, when the film passes between the two coating rollers 9, the spring 18 will deform when the coating rollers 9 are squeezed by the film, thus playing a buffering role and preventing the strength between the two coating rollers 9 from being too high, which would damage the film. In addition, the expansion of the spring 18 will keep the pressure plate 19 pressed against the connecting post 10 for a long time, preventing material slippage.

[0030] Both sides of the collection box 20 have slots 28, and both mounting brackets 6 have grooves 29 inside. A slider 30 is slidably installed inside the groove 29. One side of the slider 30 is fixedly connected to the groove 29 by a spring 31, and the other side of the slider 30 is fixedly connected to an insert 32. The insert 32 matches the slot 28. By utilizing the triangular structure of the insert 32, when the collection box 20 is pulled down, the moving collection box 20 will push the insert 32 into the groove 29, making it easy to remove the collection box 20 for cleaning.

[0031] The cleaning device 3 includes a second mounting bracket 33, and there are two mounting brackets 33. A servo motor 34 is installed on the outer side of the mounting bracket 33 near the rear of the processing table 1. The output shaft of the servo motor 34 is fixedly connected to a brush roller 35 via a coupling. The brush roller 35 is rotatably connected to the mounting bracket 33. A second brush roller 36 is movably installed at the bottom of the brush roller 35. The brush roller 35 and the second brush roller 36 cooperate with each other. The ends of the brush roller 35 and the second brush roller 36 are fixedly fitted with pulleys 37. The two pulleys 37 are connected by a transmission belt 38. The cooperation between the servo motor 34, the pulleys 37 and the transmission belt 38 realizes the synchronous rotation of the brush roller 35 and the second brush roller 36, which neutralizes the static electricity on the surface of the substrate and prevents dust adsorption or discharge.

[0032] A back plate 39 is fixedly connected to the rear side of the processing table 1. A storage tank 40 is fixedly installed on the top of the back plate 39. A spraying mechanism 41 is fixedly installed on the front side of the back plate 39. A material pipe 42 is fixedly connected between the spraying mechanism 41 and the storage tank 40. A pump body 43 is installed between the material pipe 42 and the storage tank 40. The pump body 43 works and draws liquid from the storage tank 40 through the material pipe 42. The liquid is evenly sprayed onto the surface of the substrate through the spraying mechanism 41.

[0033] The working principle of this practical application is as follows:

[0034] The film substrate is passed through the feeding roller 2, brush roller 1 35, brush roller 2 36, spraying mechanism 41 and coating roller 9 in one pass and connected to the take-up roller 5. During the winding process, the brush roller 1 35 and brush roller 2 36 are used to clean the dust on the surface. Then, the pump body 43 is activated and the liquid in the storage tank 40 is drawn through the material pipe 42. The liquid is evenly sprayed onto the surface of the substrate through the spraying mechanism 41. When the substrate passes between the two coating rollers 9, the coating rollers 9 operate evenly on the liquid on their surface as they roll. Finally, the material is collected by the take-up roller 5. The scraper 25 can clean the liquid that has accumulated on the coating rollers 9. The scraped debris is guided by the receiving edge 21 and the inclined surface of the scraper 25 and falls into the collection box 20 for collection.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
