Description

Technical Field

[0001] This utility model belongs to the field of molding machine technology, and in particular relates to a device for removing air bubbles from the surface of a membrane press. Background Technology

[0002] A membrane press is a device used to apply a thin film to the surface of a substrate, widely used in furniture manufacturing, the automotive industry, and electronic product packaging. Its main function is to use high temperature and pressure to tightly adhere decorative or protective films to the substrate surface, enhancing the product's aesthetics and durability. In furniture manufacturing, membrane presses are often used to produce laminated panels, replacing traditional painting and veneer processes, improving production efficiency and product quality. However, when the membrane press imprints the film onto the substrate surface, air bubbles often appear between the film and the substrate due to unstable air pressure and varying temperatures. Therefore, these bubbles need to be scraped off before further processing.

[0003] Existing membrane presses place the substrate to be coated on a worktable, heat the film to a certain temperature using a heating plate, and then apply a certain pressure to make the film adhere tightly to the surface of the substrate. The benefits of this equipment include improving coating quality, reducing manual operation, increasing production efficiency, and reducing production costs.

[0004] However, most existing debubbling devices use a fixed-height roller design, which cannot adjust the height of the roller according to the size and position of the bubbles inside the film. This makes it difficult to handle bubbles of different sizes and positions flexibly, resulting in residual bubbles that cannot be completely eliminated and affecting the debubbling effect. Utility Model Content

[0005] The purpose of this invention is to provide a bubble removal device for the surface of a membrane press, which aims to improve the problem that most existing bubble removal devices cannot adjust the height of the roller according to the actual situation of bubbles inside the film.

[0006] To achieve the above objectives, the membrane press surface degassing device provided in this embodiment includes a worktable. A side plate is fixedly connected to the inside of the worktable. A roller is rotatably connected to the outer wall of the side plate. A support platform is fixedly connected to the outer wall of the worktable. A protective sleeve is fixedly connected to the outer wall of the support platform. A fixed seat is fixedly connected inside the protective sleeve. A symmetrical rotating shaft is rotatably connected inside the fixed seat. A motor is fixedly connected inside the protective sleeve. The output end of the motor is fixedly connected to one end of the right rotating shaft. Gears are fixedly connected to the outer wall of the rotating shaft, and two gears mesh with each other. A movable frame is fixedly connected to the outer wall of the rotating shaft. A connecting plate is rotatably connected to the outer wall of the movable frame. A connecting seat is fixedly connected to the outer wall of the connecting plate. A support spring is provided on the outer wall of the connecting seat. A second roller is rotatably connected inside the connecting seat. A limiting component is provided inside the second roller to limit its position.

[0007] Furthermore, the limiting component includes a limiting shaft, the outer wall of which is rotatably connected to the inside of the second roller, the outer wall of the support platform is fixedly connected to a limiting plate, and the outer wall of the limiting shaft is slidably connected to the inside of the limiting plate.

[0008] Furthermore, one end of the support spring is fixedly connected to the outer wall of the support platform, and the other end of the support spring is fixedly connected to the outer wall of the connecting seat.

[0009] Furthermore, a feed hopper is fixedly connected to the outer wall of the workbench, an electric slide rail is fixedly connected to the inside of the workbench, a movable platform is slidably connected to the inside of the workbench, the outer wall of the movable platform is slidably connected to the outer wall of the electric slide rail, and a handle is fixedly connected to the outer wall of the movable platform.

[0010] Furthermore, a brush is fixedly connected inside the movable platform, a limiting roller is rotatably connected inside the movable platform, a heating rod is rotatably connected inside the limiting roller, both ends of the heating rod are fixedly connected inside the movable platform, and a scraper is fixedly connected inside the movable platform.

[0011] Furthermore, a second motor is fixedly connected inside the movable platform, and a worm gear is fixedly connected to the output end of the second motor.

[0012] Furthermore, a straight rod is rotatably connected inside the movable platform, and a worm gear is fixedly connected to the outer wall of the straight rod, with the worm meshing with the worm gear.

[0013] Furthermore, a fixing plate is fixedly connected to the outer wall of the straight rod, and a fan is fixedly connected inside the fixing plate.

[0014] The above-mentioned technical solutions in the membrane press surface degassing device provided in this embodiment of the utility model have at least one of the following technical effects:

[0015] 1. In this utility model, motor one drives shaft one to rotate, which in turn drives the movable frames on both sides to rotate together with the fixed seat. This pushes the connecting seat, allowing the limiting shaft to slide inside the limiting plate to adjust the position of roller two. This achieves the effect of controlling the distance between the two rollers, solving the problem that most existing de-bubble devices cannot adjust the height of the rollers according to the actual situation of the air bubbles inside the film. This improves the practicality of the device and expands its application range.

[0016] 2. In this utility model, a brush can be used to initially clean the surface of the film, while a motor and a worm gear drive the worm wheel to rotate, allowing the worm wheel to adjust the blowing angle of the fan. The fan then blows away the dust on the surface of the film, thereby achieving a thorough cleaning of the dust on the film surface. This improves the practicality of the device and the cleanliness of the film surface, and ensures the smooth progress of the de-bubble process. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] In one embodiment of this utility model, such as Figures 1-3 As shown, a degassing device for a membrane press is provided, comprising a worktable 1, a side plate 2 fixedly connected inside the worktable 1, a roller 3 rotatably connected to the outer wall of the side plate 2, a support platform 4 fixedly connected to the outer wall of the worktable 1, a protective sleeve 5 fixedly connected to the outer wall of the support platform 4, a fixed base 8 fixedly connected inside the protective sleeve 5, and symmetrical rotating shafts 7 rotatably connected inside the fixed base 8. A motor 6 is fixedly connected inside the protective sleeve 5, and the output end of the motor 6 is fixedly connected to one end of the right rotating shaft 7. Gears 9 are fixedly connected to the outer wall of the rotating shaft 7, and the two gears 9 mesh with each other. A movable frame 10 is fixedly connected to the outer wall of the rotating shaft 7, and the outer wall of the movable frame 10 rotates. A connecting plate 11 is connected, and a connecting seat 12 is fixedly connected to the outer wall of the connecting plate 11. A support spring 13 is provided on the outer wall of the connecting seat 12. A roller 14 is rotatably connected inside the connecting seat 12. A limit component is provided inside the roller 14 to limit the position of the roller 14. The limit component includes a limit shaft 15, the outer wall of which is rotatably connected to the inside of the roller 14. A limit plate 16 is fixedly connected to the outer wall of the support platform 4, and the outer wall of the limit shaft 15 is slidably connected to the inside of the limit plate 16. One end of the support spring 13 is fixedly connected to the outer wall of the support platform 4, and the other end of the support spring 13 is fixedly connected to the outer wall of the connecting seat 12.

[0029] Specifically, when it is necessary to adjust the distance between the rollers, motor 6 drives the right rotating shaft 7 to rotate through its output end. The right rotating shaft 7, through its cooperation with gear 9, simultaneously drives the left rotating shaft 7 to rotate synchronously. In this way, the movable frames 10 on both sides can rotate simultaneously inside the fixed seat 8. The movable frame 10 is connected to the outer wall of the connecting seat 12 through the connecting plate 11. When the movable frame 10 rotates, it can push the connecting seat 12, which allows the movable frame 10 to control the up and down movement of the second roller 14. The limiting shaft 15 slides inside the limiting plate 16, which plays the role of limiting the movement distance of the second roller 14. Thus, the second roller 14 can cooperate with the first roller 3 to squeeze the air bubbles on the film surface. This not only adjusts the distance between the rollers and ensures the removal of air bubbles, but also improves the practicality and application range of the device.

[0030] In another embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4As shown, a feed hopper 17 is fixedly connected to the outer wall of the workbench 1, and an electric slide rail 29 is fixedly connected to the inside of the workbench 1; a movable table 18 is slidably connected to the inside of the workbench 1, and the outer wall of the movable table 18 is slidably connected to the outer wall of the electric slide rail 29; a handle 19 is fixedly connected to the outer wall of the movable table 18; a brush 20 is fixedly connected to the inside of the movable table 18; a limiting roller 21 is rotatably connected to the inside of the movable table 18; a heating rod 22 is rotatably connected to the inside of the limiting roller 21; both ends of the heating rod 22 are fixedly connected to the inside of the movable table 18; a scraper 23 is fixedly connected to the inside of the movable table 18; a second motor 24 is fixedly connected to the inside of the movable table 18; a worm gear 25 is fixedly connected to the output end of the second motor 24; a straight rod 26 is rotatably connected to the inside of the movable table 18; a worm wheel 27 is fixedly connected to the outer wall of the straight rod 26; the worm gear 25 meshes with the worm wheel 27; a fixed plate 30 is fixedly connected to the outer wall of the straight rod 26; and a fan 28 is fixedly connected to the inside of the fixed plate 30.

[0031] Specifically, when cleaning the film surface is required, a brush 20 is used to initially clean the slid-in film surface, effectively removing large particles. Simultaneously, the scraper 23 not only removes dust from the film surface but also initially eliminates air bubbles inside the film. Next, driven by the output of motor 24, the worm gear 25 begins to rotate. The worm gear 25, in conjunction with the worm wheel 27, drives the straight rod 26 to rotate. The rotation of the straight rod 26 causes the fixed plate 30 to rotate around it, thereby adjusting the blowing angle of the fan 28. This ensures that the fan 28 blows air onto the film surface at the optimal angle, further cleaning the surface dust. This not only improves the practicality of the device but also enhances the cleanliness of the film surface. The refined and automated cleaning process not only effectively removes surface contaminants but also ensures the smooth progress of subsequent bubble removal, thereby improving the overall operational efficiency and the consistency of film application quality.

[0032] Working principle: When the distance between the rollers needs to be adjusted, the output of motor 6 drives the right rotating shaft 7 to rotate. This right rotating shaft 7, in conjunction with gear 9, drives the left rotating shaft 7 to rotate as well. This causes the two movable frames 10 to rotate simultaneously inside the fixed seat 8. The movable frames 10 are then connected to the outer wall of the connecting seat 12 via connecting plate 11. As the movable frames 10 rotate, they push the connecting seat 12, causing the second roller 14 to move up and down. The limiting shaft 15 slides inside the limiting plate 16, limiting the movement distance of the second roller 14. This allows the second roller 14 to cooperate with the first roller 3 to squeeze air bubbles on the film surface, thereby controlling the distance between the two rollers. The improved design enhances the device's practicality and expands its application range. When cleaning the film surface is required, the brush 20 can perform initial cleaning of the slid-in film surface, while the scraper 23 can remove dust from the film surface and initially eliminate air bubbles inside the film. Then, the output end of the motor 24 drives the worm gear 25 to rotate, which in turn works with the worm wheel 27 to drive the straight rod 26 to rotate. This, in turn, causes the fixed plate 30 to rotate around the straight rod 26, thereby adjusting the blowing angle of the fan 28. This achieves the effect of thoroughly cleaning the dust on the film surface, improving the device's practicality and the cleanliness of the film surface, and ensuring the smooth progress of the air bubble removal process.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
