Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a coating device capable of adjusting the coating area. Background Technology

[0002] In multi-coating processes, single-die coating is currently widely used. However, this traditional single-die coating device has many insurmountable drawbacks, which limit the precision, flexibility, and application range of the coating process. Specifically, in terms of coating size control, the coating size of a single die head is directly affected by the internal shims and the blade spacing. This makes it difficult to achieve precise and ideal control over the blanking and thinning areas in the middle region during multi-width processes. More importantly, a single die head cannot adjust the width of a single width individually. To adjust the width of a single width, it is necessary to redesign the shims and the entire die head advance and retract. This is not only cumbersome and time-consuming, but also has limited adjustment accuracy and poor practicality, making it difficult to meet the needs of modern production for flexible and precise coating size control. Meanwhile, regarding coating quality, due to the large area requiring slurry flow within the single die head, the slurry at the inner edge of the die head experiences significantly different compressive forces compared to the slurry in the center. The edge slurry experiences less force, resulting in uneven slurry output. This uneven output directly affects the consistency of coated product quality, leading to unstable product performance and failure to meet high-quality production standards. Furthermore, in terms of process flexibility and comparative testing, a single die head can only meet the requirement of multiple coatings of the same process slurry, and cannot conduct comparative coating tests on slurries with different formulations under the same environmental conditions. This limits the efficiency of process research and development and optimization, and is not conducive to quickly screening out better slurry formulations. It is difficult to adapt to the requirements of continuous innovation and development of coating processes. Therefore, this application proposes a coating device that can adjust the coating area to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies in multi-width coating production processes, such as the difficulty in independently adjusting the size of each width, the difficulty in simultaneously manufacturing multiple product models, the difficulty in synchronizing verification and mass production, the difficulty in verifying the comparison of different formulations under the same environment, the difficulty in achieving more uniform material output, and the high maintenance cost of wide-width die heads. Therefore, this invention proposes a coating device that can adjust the coating area.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A coating apparatus capable of adjusting the coating area includes a support, and the coating apparatus further includes: Narrow die head assemblies, wherein multiple narrow die head assemblies are provided, and all of the multiple narrow die head assemblies are disposed on the top of the bracket; The narrow die head assembly has multiple support seats installed at its bottom. The bracket has a slide rail, and a guide groove is formed on the inner front wall of the slide rail. Multiple guide blocks are slidably installed inside the guide groove. A threaded rod arranged along the width direction of the bracket is rotatably installed on the guide block on the right side. The support seat on the right side is threadedly connected to the corresponding threaded rod. A slide groove is formed on the side wall of the bracket. A slide seat corresponding to the number of guide blocks is slidably installed inside the slide groove. A drive motor is installed on the side wall of the slide seat. The drive end of the drive motor is fixedly connected to one end of the threaded rod. The bracket is provided with an adjustment component for adjusting the sliding of the narrow die head assembly in the slide rail.

[0005] In a preferred embodiment of this utility model, the two support seats on the right side are slidably mounted with the same guide rod inside. One end of the guide rod is fixedly connected to the corresponding guide block, and the other end of the guide rod is fixed to the slide seat.

[0006] In a preferred embodiment of this utility model, the adjustment assembly includes an adjustment screw rotatably installed in the slide rail, the adjustment screw extending along the length of the bracket, an adjustment motor for driving the adjustment screw to rotate installed on the side wall of the bracket, a sliding plate threaded onto the adjustment screw, the sliding plate being slidably connected in the slide rail, and the support seat located at the rear being slidably connected to the sliding plate.

[0007] In a preferred embodiment of this utility model, the slide groove is opened along the length direction of the bracket, penetrates the side wall of the bracket and communicates with the slide rail.

[0008] As a preferred embodiment of this utility model, the guide groove is a dovetail groove structure, and the shape of the guide block is adapted to the guide groove.

[0009] As a preferred embodiment of this utility model, both of the two support seats on the right side are provided with threaded through holes, and the threaded rod is threadedly connected in the corresponding threaded through holes.

[0010] As a preferred embodiment of the present invention, the narrow die head assembly includes a lower die head connected to the top of the support base and an upper die head fixed to the top of the lower die head. A discharge gap is provided between the lower die head and the upper die head. A slurry groove is provided on the top of the lower die head, and a feed port is provided on the side wall of the lower die head.

[0011] As a preferred embodiment of this utility model, the lower die head and the upper die head are each provided with an embedding groove in sequence, and a rubber pad is embedded and installed inside the embedding groove.

[0012] In a preferred embodiment of this utility model, a bearing seat is installed inside the bracket, and the bearing seat is rotatably mounted on the corresponding adjusting screw.

[0013] As a preferred embodiment of this utility model, the sliding plate is provided with multiple limiting grooves, which are opened along the axial direction of the threaded rod, and the support seat is slidably connected inside the corresponding limiting groove. Beneficial effects

[0014] 1. This utility model, by setting multiple narrow die head components, can flexibly achieve different coating widths by combining different numbers of narrow die head components. The simultaneous use of multiple sets of narrow die head components can conveniently complete multiple coating operations. Furthermore, each set of narrow die head components can individually adjust the distance between itself and the coating roller via the support base, and adjust the coating position via the slide block, thereby realizing individual adjustment of the coating thickness and coating distance for each single coating. This adjustment method is simple to operate and effectively solves the problems of existing single die heads being unable to adjust the single width individually and being cumbersome to operate, greatly improving its practicality. 2. Each narrow die head assembly of this utility model adopts a separate feed port, which greatly reduces the flow range of the slurry, thereby making the slurry more uniformly stressed during the flow process. This ensures that the slurry extruded from the discharge gap is more uniform. At the same time, different proportions of slurry can be used in different single sections without affecting each other between adjacent sections. This successfully solves the problems of uneven discharge of existing single die heads and the inability to compare different formulas under the same environment, providing convenient conditions for comparing different formulas. 3. Each narrow die head assembly of this utility model can be disassembled individually. Compared with the single die head used in existing multi-width coating, the manufacturing cost of a wider single die head is higher than that of multiple narrow dies head of equal length when added together. If die head wear occurs during use, only a single narrow die head assembly needs to be replaced, which not only reduces maintenance costs but also makes the maintenance process more convenient, overcoming the shortcomings of high maintenance costs and inconvenient replacement of existing single dies head.

[0015] This invention effectively solves the problems of existing single-die heads being unable to adjust the width of a single section independently and being cumbersome to operate, thus greatly improving practicality. It also solves the problems of uneven material output and inability to compare different formulas under the same environment, providing convenient conditions for comparing different formulas, reducing maintenance costs, and making the maintenance process more convenient. It overcomes the shortcomings of existing single-die heads, such as high maintenance costs and inconvenient replacement. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0019] Reference Figures 1-5 A coating device capable of adjusting the coating area includes a support 1 and a coating die head adjustablely disposed on the support 1. The coating die head is composed of multiple narrow die head assemblies 2 distributed along the length direction of the support 1. Multiple support seats 3 are installed at the bottom of the narrow mold head assembly 2. A slide rail is provided on the bracket 1. A guide groove 4 is provided on the inner wall of the front side of the slide rail. Multiple guide blocks 5 are slidably installed inside the guide groove 4. A threaded rod 8 is rotatably installed on the guide block 5 on the right side, which is set along the width direction of the bracket 1. The support seat 3 on the right side is threadedly connected to the corresponding threaded rod 8. A slide groove 6 is provided on the side wall of the bracket 1. A slide seat 7 corresponding to the number of guide blocks 5 is slidably installed inside the slide groove 6. A drive motor 9 is installed on the side wall of the slide seat 7. The drive end of the drive motor 9 is fixedly connected to one end of the threaded rod 8. An adjustment component is provided on the bracket 1 for adjusting the sliding of the narrow mold head assembly 2 in the slide rail.

[0020] The coating die head of this coating device consists of multiple narrow die head assemblies 2 distributed along the length of the support 1, realizing the basic layout for multi-width coating. The narrow die head assembly 2 is connected to the support 1 through the support seat 3 at the bottom. The support seat 3 can slide along the slide rail on the support 1. The guide block 5 slides in the guide groove 4 to provide guidance for the movement of the support seat 3. The drive motor 9 is installed in the slide groove 6 of the support 1 through the slide seat 7. Its drive end is connected to the threaded rod 8. The threaded rod 8 is threadedly connected to the support seat 3. When the drive motor 9 works, the threaded rod 8 rotates and drives the support seat 3 to move along the width direction of the support 1, thereby adjusting the distance between the narrow die head assembly 2 and the coating roller. The sliding of the slide seat 7 in the slide groove 6 can be used to adjust the coating position of the narrow die head assembly 2.

[0021] As a technical optimization of this utility model, the two support seats 3 on the right side are internally slidably installed with the same guide rod 10. One end of the guide rod 10 is fixedly connected to the corresponding guide block 5, and the other end of the guide rod 10 is fixed to the slide seat 7. The two sets of support seats 3 at the bottom of each narrow mold head assembly 2 form a symmetrical support structure. One set of support seats 3 is threadedly connected to the threaded rod 8 to realize movement as a power transmission end; the other set of support seats 3 is slidably sleeved on the guide rod 10. The two ends of the guide rod 10 are fixed to the guide block 5 and the slide seat 7 respectively, providing stable guidance for the movement of the support seat 3 and preventing the narrow mold head assembly 2 from tilting or deviating during movement.

[0022] In one optimized technical solution of this utility model, the adjustment component includes an adjustment screw 12 rotatably installed in a slide rail. The adjustment screw 12 extends along the length of the bracket 1. An adjustment motor 13 is installed on the side wall of the bracket 1 to drive the adjustment screw 12 to rotate. A slide plate 11 is threadedly connected to the adjustment screw 12. The slide plate 11 is slidably connected in the slide rail. A support seat 3 located on the rear side is slidably connected to the slide plate 11. By driving the adjustment screw 12 to rotate through the adjustment motor 13, the adjustment screw 12 drives the slide plate 11, which is threadedly connected to it, to slide in the slide rail, thereby adjusting the position of the narrow die head assembly 2 on the bracket 1.

[0023] As a technical optimization of this utility model, the slide groove 6 is opened along the length direction of the bracket 1, penetrates the side wall of the bracket 1 and is connected to the slide rail. The slide groove 6 is opened along the length direction of the bracket 1 and penetrates the side wall and is connected to the slide rail, so that the sliding direction of the slide block 7 is consistent with the distribution direction of the narrow mold head assembly 2. At the same time, it facilitates the linkage between the slide block 7 and the support base 3, guide block 5 and other structures, and ensures that when the slide block 7 drives the drive motor 9 and the threaded rod 8 to move, it can coordinate with the position adjustment of the narrow mold head assembly 2.

[0024] As a technical optimization of this utility model, the guide groove 4 is a dovetail groove structure, and the shape of the guide block 5 is adapted to the guide groove 4. The guide groove 4 adopts a dovetail groove structure, and the shape of the guide block 5 is adapted to the dovetail groove, so that the guide block 5 is restricted in the groove during the sliding process and cannot be disengaged in a direction perpendicular to the sliding direction. This ensures that the guide block 5 always provides stable guidance for the support seat 3 and avoids affecting the adjustment accuracy of the narrow mold head assembly 2 due to the deviation of the guide block 5.

[0025] As a technical optimization of this utility model, both support seats 3 on the right side are provided with threaded through holes, and the threaded rod 8 is threadedly connected in the corresponding threaded through holes. The threaded through holes on the support seats 3 and the threaded rod 8 form a threaded transmission pair. When the drive motor 9 drives the threaded rod 8 to rotate, the force between the threads will convert the rotational motion into the linear motion of the support seat 3, so as to realize the precise movement of the narrow mold head assembly 2 along the width direction of the bracket 1. Moreover, the threaded transmission has self-locking property and can maintain the current position when the drive stops.

[0026] As a technical optimization of this utility model, the narrow die head assembly 2 includes a lower die head 21 connected to the top of the support base 3 and an upper die head 22 fixed to the top of the lower die head 21. A discharge gap is provided between the lower die head 21 and the upper die head 22. A slurry groove 24 is provided on the top of the lower die head 21. An inlet 25 is provided on the side wall of the lower die head 21. The lower die head 21 and the upper die head 22 of the narrow die head assembly 2 cooperate to form a discharge gap. Slurry enters the slurry groove 24 of the lower die head 21 from the inlet 25 and is then coated onto the substrate through the discharge gap. Each narrow die head assembly 2 is independently provided with an inlet 25 and a slurry groove 24, so that the slurry flow area of ​​each assembly is limited to its own range.

[0027] As a technical optimization of this utility model, the lower die head 21 and the upper die head 22 are each provided with an embedding groove in sequence. A rubber pad 23 is embedded and installed inside the embedding groove. The rubber pad 23 is elastic and can fill the tiny gap between the two dies. At the same time, it plays a buffering role when the dies are assembled or adjusted, ensuring the sealing of the discharge gap, preventing the slurry from leaking from the gap, and reducing the rigid friction between the dies.

[0028] As a technical optimization of this utility model, a bearing seat 15 is installed inside the bracket 1. The bearing seat 15 is provided with two sets of bearings, left and right. One end of the adjusting screw 12 is connected to the inner side of one set of bearings. The bearing seat 15 improves the stability of the rotation of the adjusting screw 12.

[0029] In one technical optimization of this utility model, the slide plate 11 is provided with multiple limiting grooves 14. The limiting grooves 14 are opened along the axial direction of the threaded rod 8. The support seat 3 is slidably connected inside the corresponding limiting groove 14. The limiting grooves 14 can limit and guide the sliding of the support seat 3, thereby improving the stability of the support seat 3 sliding on the slide plate 11.

[0030] It should be noted that the specific models of drive motor 9 and regulating motor 13 used are to be selected by those skilled in the art, and the above-mentioned drive motor 9 and regulating motor 13 are all existing technologies, which will not be elaborated on in this solution.

[0031] The working principle of this utility model is as follows: In use, the drive motor 9 and the regulating motor 13 are first connected to an external power source. Then, multiple narrow die head assemblies 2 are distributed along the length of the support 1 to form the basis for multi-width coating. The slide plate 11 at the bottom of each narrow die head assembly 2 can slide along the slide rail of the support 1. The guide block 5 slides in the guide groove 4 for guidance. The drive motor 9 is installed on the slide seat 7 and is connected to the internal thread of the support seat 3 through the threaded rod 8, driving the narrow die head assembly 2 to move along the width of the support 1 and adjust the distance from the coating roller. The slide seat 7 can adjust the coating position by sliding in the slide groove 6. The two support seats 3 of each narrow die head assembly 2, together with the threaded rod 8 and the guide rod 10, ensure stable movement. The dovetail groove structure of the guide groove 4 and the guide block 5 are adapted to enhance the reliability of guidance. The lower die head 21, upper die head 22 and rubber pad 23 of the narrow die head assembly 2 itself ensure that the slurry flows out evenly from the feed port 25 through the slurry groove 24 and the discharge gap.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
