Description

Technical Field

[0001] This utility model relates to the technical field of membrane coating device, and in particular to a membrane coating device. Background Technology

[0002] Melamine board, also known as melamine-impregnated paper-faced engineered wood, is a decorative board made by soaking paper with different colors or textures in melamine resin adhesive, drying it to a certain degree of curing, and then laying it on the surface of particleboard, moisture-resistant board, medium-density fiberboard, plywood, blockboard, multi-layer board or other hard fiberboard, and then hot-pressing it.

[0003] A film is laid on the surface of the melamine board. When laying the film, the roll of film needs to be released first, then a layer of glue is applied to the film, and then it is laid on the surface of the melamine board. This type of structure can be referenced by the fully automatic vertical laminating machine disclosed in Chinese Patent Publication No. CN205255744U, which includes a frame, a film feeding section, a paper feeding section, a film output section, a drying roller, and a pressure roller. The film feeding section and the paper feeding section are respectively arranged on the front and rear sides of the frame. A glue application section is provided between the film feeding section and the drying roller. The frame is also equipped with glue application rollers that match the glue application section.

[0004] Existing adhesive coating structures typically use adhesive coating rollers. A pushing device pushes the adhesive coating rollers to the position of the membrane material, and adhesive is applied by roller coating. However, this method of adhesive coating is prone to poor coating due to the vibration generated during membrane material transportation.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

Detailed Implementation

[0029] This utility model provides a film coating device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0030] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Please refer to Figures 1 to 5 This embodiment discloses a film coating apparatus, comprising:

[0032] Rack 21;

[0033] The translation component 22 includes a first drive device 221 disposed on the upper end of the frame 21 and capable of being driven along the y direction, and a mounting base 222 connected to the output end of the first drive device 221;

[0034] The feeding assembly 23 includes an air shaft 231 rotatably mounted on the mounting base 222 and used for feeding out the film material 62, a magnetic powder brake 232 fixed to the mounting base 222 and detachably connected to one end of the air shaft 231, and the other end of the air shaft 231 is mounted on the mounting base 222.

[0035] The pressure roller assembly 24 includes a pressure roller frame 241 mounted on a mounting base 222, a first pressure roller 242 and a second pressure roller 243 rotatably mounted on the pressure roller frame 241, wherein the first pressure roller 242 and the second pressure roller 243 have a first gap.

[0036] The scraper 25 has a V-shaped structure at the end facing the first gap, and the V-shaped structure has several spray holes distributed along the y direction.

[0037] The distance adjustment component 26 is provided on the mounting base 222 and is used to drive the scraper 25 to move toward the pressure roller assembly 24, or to drive the pressure roller assembly 24 to move toward the scraper 25, so as to shorten the distance between the V-shaped structure and the first gap along the x direction.

[0038] In this embodiment, the film coating device can pre-install a roll of film 62 on an air shaft 231. A magnetic powder brake 232 drives the air shaft 231 to rotate, thus releasing the film. The magnetic powder brake 232 can also control the film release speed. When the film 62 is conveyed to the position of the doctor blade 25, a pressure roller assembly 24 is added to one side of the doctor blade 25. The V-shaped structure of the doctor blade 25 is inserted into the first gap formed by the first pressure roller 242 and the second pressure roller 243. Figure 3 As shown, the membrane material 62 forms a "V" shaped structure at this position. The membrane material 62 is pressed by the V-shaped structure of the scraper 25, which can avoid poor adhesive application due to membrane vibration. The structure is ingenious.

[0039] Furthermore, the scraper 25 has an internal glue channel, and the upper end of the scraper 25 is provided with an interface connected to the glue channel. The interface is connected to the glue storage tank through a pipe, and glue is introduced into the glue channel through the glue storage tank. The V-shaped structure of the scraper 25 has several spray holes connected to the glue channel along the y direction. By controlling the pressure inside the glue channel, the glue is sprayed out from the spray holes, thereby uniformly coating the glue onto the surface of the film material 62, resulting in a more uniform coating.

[0040] In addition, this embodiment also adds a translation component 22, which can drive the mounting base 222 to adjust its position along the y-direction through the first driving device 221, thereby adjusting the film laying position of the membrane material 62 along the y-direction to adapt to different application scenarios.

[0041] This embodiment also adds a distance adjustment component 26. During the film loading and debugging stage, the distance adjustment component 26 can be used to drive the doctor blade 25 away from the pressure roller assembly 24, or drive the pressure roller assembly 24 away from the doctor blade 25, so that the film material 62 can pass smoothly between the doctor blade 25 and the pressure roller assembly 24. Then, the distance adjustment component 26 can drive the doctor blade 25 towards the pressure roller assembly 24, or drive the pressure roller assembly 24 towards the doctor blade 25, to shorten the distance between the V-shaped structure and the first gap along the x-direction, so that the film material 62 forms a "V"-shaped structure at this position. The V-shaped structure of the doctor blade 25 is used to press the film material 62 tightly to prevent the film material 62 from vibrating. Moreover, the distance adjustment component 26 can also adjust the distance according to the thickness of the film material 62 to adapt to different production needs.

[0042] Please refer to Figure 4 The translation component 22 in this embodiment also includes a first guide rail 223 fixed to the upper end of the frame 21 and a first slider 224 fixed to the lower end of the mounting base 222. The first slider 224 slides along the first guide rail 223 in the y direction. By setting the first slider 224 and the first guide rail 223, the stability of the mounting base 222 moving in the x direction is improved.

[0043] The distance adjustment assembly 26 includes a second drive device 261 fixed to the mounting base 222 and driven along the x-direction, a second guide rail 262 fixed to the outside of the pressure roller frame 241, and a second slider 263 fixed to the inside of the mounting base 222. The second slider 263 slides along the second guide rail 262 along the x-direction. By setting the second slider 263 and the second guide rail 262, the smoothness of the movement of the pressure roller frame 241 along the x-direction is improved.

[0044] In this embodiment, the output end of the second driving device 261 is connected to the pressure roller frame 241, and the scraper 25 is fixed to the mounting base 222, that is, the pressure roller frame 241 can move, but the scraper 25 does not move.

[0045] It should be noted that the fact that the pressure roller frame 241 is movable while the scraper 25 is stationary is only one preferred embodiment. In other embodiments, the scraper 25 can also be designed to be movable while the pressure roller frame 241 is stationary, and it is not limited to the structure of this embodiment.

[0046] Furthermore, a drying device 27 is also fixed on the mounting base 222. The output end of the drying device 27 faces the released membrane material 62, which speeds up the drying speed of the adhesive on the membrane material 62. Then the film is laid on the plate below, which improves the bonding speed between the membrane material 62 and the plate.

[0047] Please refer to Figure 1 In this embodiment, the other end of the air shaft 231 is fitted with a bearing 233, and the air shaft 231 is mounted on the mounting base 222 through the bearing 233. By setting the bearing 233, the rotational stability is better.

[0048] The membrane coating device also includes a tension adjustment assembly 28, which includes a first conveying roller 281, a second conveying roller 282, and a third conveying roller 283 rotatably mounted on a mounting base 222. The first conveying roller 281, the second conveying roller 282, and the third conveying roller 283 are arranged in a triangular pattern. The membrane 62 passes around the first conveying roller 281, the second conveying roller 282, and the third conveying roller 283 in sequence. The mounting base 222 is provided with a first waist hole 284 extending in the x-direction. The end of the third conveying roller 283 can be adjusted along the first waist hole 284 to adjust its position in the x-direction. By adjusting the position of the third conveying roller 283 in the x-direction, the tension of the membrane 62 can be adjusted, making the membrane 62 more tightly stretched, avoiding wrinkles in the membrane 62, and ensuring the subsequent coating quality of the membrane 62.

[0049] The film coating device also includes a lifting adjustment mechanism 29, which includes a lifting drive device 291 fixed to the frame 21 and a limiting plate 292 connected to the output end of the lifting drive device 291. The limiting plate 292 limits the height of the film 62 to ensure the subsequent coating quality.

[0050] The film coating device also includes a fourth conveying roller 210 rotatably mounted on the frame 21. The fourth conveying roller 210 is located directly below the third conveying roller 283. The frame 21 is provided with a second waist hole 211 extending in the x direction. The end of the fourth conveying roller 210 can be adjusted along the second waist hole 211 to adjust its position in the x direction. The output flatness of the film 62 is controlled by setting the fourth conveying roller 210, which is a clever structure.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this invention.
