[0002] In modern industrial production, coating processes are widely used in numerous industries, such as electronics, printing, packaging, and new energy. Taking lithium-ion battery production as an example, precise coating processes play a crucial role in ensuring battery performance. In the printing and packaging industry, high-quality coating provides products with better protection and decorative effects, meeting consumers' increasingly sophisticated aesthetic and functional needs. With the rapid iteration and upgrading of products across industries and intensified market competition, the requirements for the precision, adaptability, and production efficiency of coating processes have reached unprecedented levels.

[0003] In traditional coating equipment, the technology for controlling coating thickness and length using coating dies is relatively limited. Most existing coating dies have a fixed structural design, making it difficult to flexibly adjust the slit length between the lower and upper dies. Furthermore, the installation of traditional die pads lacks precise positioning, requiring workers to repeatedly adjust the installation position during replacement, further increasing replacement time and reducing equipment maintenance efficiency. To address this technical problem, this application proposes a coating die with adjustable coating length. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of a coating die head with adjustable coating length, including a lower die head 1, an upper die head 2 disposed on the top side of the lower die head 1, a positioning slide rod 3 fixedly connected to the top side of the lower die head 1, a liquid groove 5 formed on the top side of the lower die head 1, a slide rod 4 fixedly connected to the inner wall of the liquid groove 5, a baffle 6 slidably connected to the outer wall of the slide rod 4, a sliding groove formed at the middle of the top side of the baffle 6, a top block 12 slidably connected to the inner wall of the sliding groove, a positioning groove 10 formed on the bottom side of the upper die head 2, a support rod 13 fixedly connected to the bottom side of the sliding groove, and the top block 12 sleeved on the outer wall of the support rod 13. A spring 14 is provided on the outer wall of the upper mold 2. One end of the spring 14 is connected to the bottom side of the top block 12, and the other end of the spring 14 is connected to the bottom side of the slide groove to control the limit between the top block 12 and the positioning groove 10. A mold head gasket 7 is sleeved on the outer wall of the positioning slide rod 3. A plate side gasket 8 is provided on the top side of the baffle 6. A T-shaped groove 11 is opened on the side of the plate side gasket 8 and the mold head gasket 7 that is close to the top side of the baffle 6. An I-shaped insertion shaft 9 is provided inside the three adjacent T-shaped grooves 11 to install the mold head gasket 7 and the plate side gasket 8. A hook mounting hole 15 is opened on the top side of the upper mold 2.

[0025] Specifically, the lifting ring is connected to the upper mold head 2 through the hook mounting hole 15, and the upper mold head 2 is raised using the lifting ring. Next, according to actual needs, different mold head gaskets 7 are installed on the top side of the lower mold head 1. Then, the plate side gasket 8 is installed on the top side of the baffle 6. Afterwards, the I-shaped plug shaft 9 is inserted into the T-shaped grooves 11 opened on the mold head gasket 7, the plate side gasket 8, and the baffle 6, thereby fixing the mold head gasket 7 and the plate side gasket 8 to the baffle 6. Since the baffle 6 can slide on the outer wall of the slide rod 4, the space size of the liquid tank 5 can be adjusted by sliding the baffle 6. Subsequently, the upper mold head 2 is installed on the top side of the lower mold head 1 and fixed with bolts. After installation, the upper mold head 2 will press against the top side of the mold head gasket 7 and the plate side gasket 8, while the mold head gasket 7 and the plate side gasket 8 will press between the lower mold head 1 and the upper mold head 2. At this time, the top block 12 at the middle of the baffle 6 will be engaged in the positioning groove 10 on the bottom side of the upper die head 2 under the action of the spring 14, thereby adjusting the slit length between the lower die head 1 and the upper die head 2, and thus achieving the purpose of adjusting the coating length. In addition, the die head gasket 7 can be positioned by the positioning slide rod 3 and the I-shaped plug shaft 9, making the replacement process of the die head gasket 7 more convenient and precise.

[0026] Reference Figures 2-4 The middle end of the plate side pad 8 is sleeved on the outer wall of the top block 12, the top block 12 is set inside one of the positioning grooves 10, and the upper mold head 2 is sleeved on the outer wall of the positioning slide rod 3.

[0027] Specifically, the plate side gasket 8 and the die head gasket 7 can be pressed between the lower die head 1 and the upper die head 2 to adjust the slit length between the lower die head 1 and the upper die head 2. When the top block 12 is pressed into one of the positioning grooves 10, it can limit the sliding of the baffle 6 on the outer wall of the slide rod 4. Together with the die head gasket 7 and the plate side gasket 8, the space of the liquid tank 5 and the slit length between the lower die head 1 and the upper die head 2 can be adjusted.

[0028] Working principle: The upper mold head 2 is raised by connecting the lifting ring through the hook mounting hole 15. Then, different mold head shims 7 are installed on the top side of the lower mold head 1 as needed. The plate side shims 8 are installed on the top side of the baffle 6. The I-shaped plug shaft 9 is inserted into the T-shaped groove 11 opened on the mold head shims 7, plate side shims 8 and baffle 6 to fix the mold head shims 7 and plate side shims 8 on the baffle 6. The baffle 6 can slide on the outer wall of the slide rod 4 to adjust the space of the liquid tank 5. The upper mold head 2 is then installed on the top side of the lower mold head 1 and then bolted... After installation, the upper die head 2 presses against the top of the die head pad 7 and the plate side pad 8, and the die head pad 7 and the plate side pad 8 press between the lower die head 1 and the upper die head 2. At this time, the top block 12 at the middle of the baffle 6 will be locked inside the positioning groove 10 on the bottom side of the upper die head 2 by the action of the spring 14, so that the length of the slit between the lower die head 1 and the upper die head 2 can be adjusted, thereby adjusting the coating length. The positioning slide rod 3 and the I-shaped plug shaft 9 can be used to position the installation of the die head pad 7, making the replacement of the die head pad 7 more convenient and accurate.
