Description

Technical Field

[0001] This utility model belongs to the field of thin film production technology, and in particular relates to a coating device for thin film production. Background Technology

[0002] In the current booming development of the new energy industry, the adhesive film of new energy battery packs is of paramount importance. It has a profound impact on the performance, safety and service life of batteries. During the production process of battery packs, the adhesive film needs to be coated evenly and precisely on specific parts to ensure the sealing, stability and structural strength of the battery pack. To achieve this goal, coating equipment for film production has emerged. Its performance directly affects the coating quality of the adhesive film and plays a decisive role in the overall quality of new energy battery packs.

[0003] However, existing glue coating equipment often results in uneven glue application during use, leading to situations where the glue is too thick in some areas, affecting subsequent drying, or too thin in others, making it difficult to meet quality requirements, thus reducing the overall product quality. Utility Model Content

[0004] The purpose of this invention is to provide a coating device for film production. By setting up a coating section, it solves the problems of uneven glue application in existing coating devices, which results in localized areas of thick glue that affect subsequent drying, and localized areas of thin glue that fail to meet quality requirements, thereby reducing the overall product quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a coating device for film production, comprising two supports, and further comprising: a coating section installed within the two supports; a buffer section disposed within the two supports; the coating section comprising a spreading assembly located within the two supports; and an adhesive application assembly disposed within the two supports; the spreading assembly comprising a connecting block fixedly connected between the two supports, a spreading cloth belt fixedly connected to the right side of the connecting block, a roller rotatably connected to the inner wall of the connecting block, and an extrusion plate fixedly connected to the rear side of the connecting block; wherein the spreading cloth belt is a soft, elongated material.

[0007] Furthermore, the buffer includes a limiting component installed within two supports; and an adjusting component located between the two supports; wherein the adjusting component is located within the limiting component.

[0008] Furthermore, the adhesive application assembly includes a connecting pipe disposed on the top of the connecting block one, and an adhesive distributing component is disposed within the connecting block one; wherein, the connecting pipe is an inverted U-shaped pipe, and the adhesive distributing component includes a connecting groove one formed within the connecting block one, a connecting groove two formed within the connecting block one, the bottom of the connecting groove one being connected to the connecting groove two, the bottom of the connecting pipe being connected to the connecting groove one, and a plurality of connecting groove three formed on the right side of the connecting groove two, the right sides of the plurality of connecting groove three extending outside the connecting block one; wherein, the plurality of connecting groove three are arranged in a linear array, and through the linear array of connecting groove three, the adhesive can be evenly distributed and transported to the outside of the connecting block one, thereby achieving uniform adhesive application to the material.

[0009] Furthermore, the limiting component includes a connecting block two fixedly connected between two supports, a slider one slidably connected to the inner wall of the connecting block two, and a guide member provided on the outside of the connecting block two; wherein, the slider one is a C-shaped block, and the guide member includes two rollers two rotatably connected to the inner wall of the slider one, and a roller three rotatably connected to the inner wall of the connecting block two; wherein, the two rollers two are mirror images of each other, and the roller three is located on the left side of the connecting block two. By using the two mirror images of the rollers two and the roller three located on the left side of the connecting block two to cooperate, the material can be limited and guided to prevent the material from deviating.

[0010] Furthermore, the adjustment assembly includes a slider two slidably connected to the inner wall of the connecting block two. Several springs are fixedly connected to the bottom of the slider two, and the bottoms of each spring are fixedly connected to the slider one. A rotating component is provided on the connecting block two. The slider two is an elongated block. The rotating component includes a threaded rod rotatably connected to the top of the slider two. The top of the threaded rod extends outside the connecting block two, and the outer wall of the threaded rod is threadedly connected to the connecting block two. A handle is fixedly connected to the outer wall of the threaded rod, and the threaded rod passes through the handle. The threaded rod is located at the central axis of the connecting block two. Rotation of the threaded rod drives the slider two to move up and down. In conjunction with the springs, the height of the slider one and the roller two can be adjusted to accommodate materials of different thicknesses.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a coating section, the connecting pipe guides the adhesive into the first connecting groove, which then splits into several connecting grooves in a linear array to the third connecting groove, allowing the adhesive to drip evenly onto the film surface. The soft coating cloth belt in the coating assembly works in conjunction with the extrusion plate to squeeze and smooth the adhesive during film movement. At the same time, roller one provides stable support for the film, ensuring that the film is subjected to uniform force during the coating process. This effectively avoids the problem of local adhesive accumulation or uneven coating, improves the flatness and consistency of film coating, and thus ensures the overall product quality.

[0013] 2. By setting up a buffer section, two mirror-mounted rollers perform secondary compression on the passing film, further ensuring uniform adhesive application. At the same time, the film's movement compresses rollers two, causing slider one to compress the spring. The elastic force generated by the spring's elastic deformation can buffer the tension fluctuations of the film, preventing damage due to sudden tension changes. In the adjustment component, turning the handle can drive slider two via the threaded rod to adjust the spring compression, allowing for flexible changes in spring force to adapt to the processing needs of films of different thicknesses or materials, thus enhancing the applicability and stability of the device.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The buffer section 3 includes a limiting component 31, which is installed within two supports 101; and an adjusting component 32, which is located between the two supports 101. The adjusting component 32 is located within the limiting component 31. The limiting component 31 includes a connecting block 311 fixedly connected between the two supports 101.

The two rollers 313 are mirror images of each other, and the roller 314 is located to the left of the connecting block 311. The adjusting component 32 includes components slidably connected to the connecting block 311. The inner wall has a second slider 321, and several springs 322 are fixedly connected to the bottom of the second slider 321. The bottom of each spring 322 is fixedly connected to the first slider 312. A rotating component is provided on the second connecting block 311. The second slider 321 is a long strip block.

The glue entering the connecting groove 1 222 will be discharged through connecting groove 2 223 from several connecting grooves 3 224, and finally drip onto the film. As the film moves, the glue will flow between the coating belt 212 and the extrusion plate. The adhesive is spread evenly under the pressure of 214, and the film passes through the bottom of the two rollers 313, so that the adhesive is further spread evenly. The film will squeeze the rollers 313, causing the slider 312 to slide within the connecting block 311, thereby compressing the spring 322, causing it to undergo elastic deformation and generate elastic force. When it is necessary to adjust the elastic force of the spring 322, the handle 324 can be turned to move the threaded rod 323 downward, thereby squeezing the spring 322 through the slider 321, compressing it and generating elastic force. At this time, the elastic coefficient of the spring 322 will increase.
