[0003] In the existing technology, the guide roller of the gravure coating machine is a vacuum adsorption passive roller. Since the traction power of the vacuum adsorption roller is limited, the tension in the direction of the guide roller is too small when making wide films, which seriously affects the coating effect.

[0019] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0020] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] See Figures 1-2 , Figure 1 This is one of the schematic diagrams of the coating machine and the proximity roller device in the embodiment. Figure 2 This is a second schematic diagram of the coating machine and proximity roller device in the embodiment. The active proximity roller structure of the coating machine in this example includes a coating machine 1 and a proximity roller device 2. The coating machine has a coating roller mechanism 11 for coating operations. The proximity roller 2 is arranged adjacent to the coating roller 11. The proximity roller device 2 includes a proximity drive mechanism 21 and multiple proximity rollers 22, which are located on the proximity drive mechanism 21 and parallel to the coating roller 11. During operation, driven by the proximity roller drive mechanism 21, the multiple proximity rollers 22 actively approach the coating roller 11, ensuring the film is stably close to the coating roller mechanism 11, effectively eliminating the problem of uneven coating thickness caused by unstable film tension when the passive proximity roller is operating. In specific implementation, the proximity roller drive mechanism 21 consists of a motor, a lead screw, and a slide rail slider assembly. In this example, the coating roller mechanism 11 consists of a drive motor 111 and a gravure roller 112.

[0022] Specifically, the approach roller device 2 also includes a synchronous transmission mechanism 23, which is located between the multiple approach rollers 22 and is connected to the multiple approach rollers 22 in a driving manner. In this example, there are two approach rollers 22, and the synchronous transmission mechanism 23 is located between the two approach rollers 22. The synchronous transmission mechanism 23 adopts a synchronous belt drive system to realize the synchronous rotation of the two approach rollers 22 and ensure the stability of the coating operation.

[0023] Preferably, the proximity roller 2 further includes a fine-tuning mechanism 24, which is driven by the proximity drive mechanism 21. The fine-tuning mechanism 24 includes a fine-tuning drive 241 and a fine-tuning movement mechanism 242. The proximity roller 22 and the synchronous transmission mechanism 23 are both mounted on the fine-tuning movement mechanism 242 and are driven by the fine-tuning drive mechanism 241. In a specific implementation, the fine-tuning drive 241 consists of a manual knob and a lead screw, and the fine-tuning movement mechanism 242 consists of a slide rail and slider assembly. In use, when the proximity drive mechanism 21 drives the proximity roller 22 close to the coating roller mechanism 11, the distance between the proximity roller 22 and the synchronous roller mechanism 11 is fine-tuned by adjusting the fine-tuning drive mechanism 241, thereby controlling the coating thickness of the film.

[0024] Furthermore, the coating machine 1 also includes a material basin mechanism 12 and a scraper mechanism 13. The coating roller mechanism 11 is located above the material basin mechanism 12, and the scraper mechanism 13 is mounted on the material basin mechanism 12 and located on the side of the coating roller mechanism 2 facing away from the roller device 2. The scraper mechanism 13 is parallel to the coating roller mechanism 2 and directly opposite the coating roller mechanism 2.

[0025] The material tray mechanism 12 includes a lifting mechanism 121 and a material tray 122. The material tray 122 is mounted on the lifting mechanism 121, and the scraper mechanism 13 is mounted on the material tray 122. The coating roller mechanism 11 is located above the material tray 122. The lifting mechanism 121 drives the material tray 122 to move closer to or away from the coating roller mechanism 11. The lifting mechanism 121 is also composed of a motor, a lead screw, and a slide rail slider assembly. The material tray mechanism 12 also includes a rotating mechanism 123, which is mounted on the lifting mechanism 121. The material tray 122 is drivenly connected to the rotating mechanism 123. The rotating mechanism 123 uses a servo motor. It can be understood that the lifting mechanism 121 can not only adjust the height of the material tray 122, thereby adjusting the distance between the scraper mechanism 13 and the coating roller mechanism 11, but also, in conjunction with the flipping mechanism 123, realize the lifting and flipping of the material tray 122, facilitating cleaning.

[0026] Preferably, the material basin 122 has a storage cavity 1221, which is provided with multiple baffles 12211. The baffles 12211 divide the storage cavity 1221 into a feed trough 12212, a paint trough 12213, and an overflow trough 12214. The scraper mechanism 13 is located on the side of the material basin 122 near the overflow trough 12214. The overflow trough 12214 is connected to an external loading transfer tank. This effectively prevents paint dripping and air bubbles from forming when the scraper mechanism 13 scrapes paint off the coating roller mechanism 11, thereby further improving the quality of product production.

[0027] Specifically, the scraper mechanism 13 includes a scraper 131 and a transverse drive mechanism 132. The transverse drive mechanism 132 is arranged along the length of the material tray 122, and the scraper 131 is driven by the transverse drive mechanism 132 and faces the coating roller mechanism 11. Similarly, the transverse drive mechanism 132 is also composed of a motor, a lead screw, and a slide rail slider assembly. During operation, driven by the transverse drive mechanism 132, the scraper 131 reciprocates along the length of the coating roller assembly 11. In this way, even if the scraper 131 has a small nick, it can be cleaned by the reciprocating transverse movement of the scraper 131, which greatly increases the service life of the scraper 131 and ensures that the coating on the coating roller mechanism 11 is uniform.

[0028] Preferably, the material tray mechanism 12 further includes a lifting and fine-tuning mechanism 124, which is mounted on the lifting mechanism 121, and the rotating mechanism 123 is mounted on the lifting and fine-tuning mechanism 124. The structure and principle of the lifting and fine-tuning mechanism 124 are the same as those of the fine-tuning mechanism 24, and will not be repeated here. It can be understood that the lifting and fine-tuning mechanism 124 can further fine-tune the distance between the scraper 131 and the coating roller mechanism 11, making the scraper closer to the coating roller mechanism 11 while preventing collisions between the scraper 131 and the coating roller mechanism 11.

[0029] In summary, in this example, by setting an active approach roller device on the coating machine, the stability of film tension during coating is improved, effectively eliminating the problem of uneven coating thickness caused by unstable film tension when the passive approach roller is working.

[0030] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
