Description

Technical Field

[0001] This utility model relates to the technical field of coating equipment, and in particular to a dual-purpose precision flatbed coating machine. Background Technology

[0002] In modern industrial production and laboratory research, coating processes are widely used for surface treatment and functional coating preparation of materials such as films and fabrics. Traditional coating equipment typically employs a single coating method, making it difficult to meet diverse coating needs, especially when high precision and uniformity are required. Existing coating machines often rely on manual operation or simple mechanical control, leading to problems such as uneven coating thickness, low coating efficiency, and poor repeatability. Furthermore, traditional equipment has limited material adsorption capacity during the coating process, easily resulting in coating defects due to incomplete material adhesion, affecting the quality of the final product. Simultaneously, existing coating devices have limitations in liquid supply and coating head control, such as unstable liquid flow and uneven contact between the coating head and material, further limiting the improvement of coating effects. Therefore, developing a coating device capable of multiple coating methods, possessing high-precision control capabilities, and effectively solving the material adsorption problem has become an important issue urgently needing to be addressed in the current technological field. This utility model aims to overcome the shortcomings of the existing technology by providing a dual-purpose precision flatbed coating machine to meet the needs of efficient and precise coating. Utility Model Content

[0003] The purpose of this invention is to provide a dual-purpose precision flatbed coating machine to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A dual-purpose precision flatbed coating machine includes main components such as a vacuum adsorption plate, a coating device, a receiving tray, a moving frame, a servo motor, a commutator, a lifting screw, a slot coating head, a lifting cylinder, and a coating roller. The vacuum adsorption plate is mounted on the machine platform and has a negative pressure generating device on its surface to adsorb the film or fabric and fix its position, preventing displacement during coating. Furthermore, a receiving tray is fixedly installed on one side of the vacuum adsorption plate, storing the liquid to be coated, such as adhesive or surface treatment liquid, for the coating blade to apply.

[0005] The coating device is mounted on a vacuum adsorption plate and can move laterally relative to the plate. Specifically, the coating device includes a movable frame with a base plate at its bottom. The base plate is connected to the output end of a left-right translation component, which drives the coating device to move linearly horizontally. Particularly, a pair of servo motors are fixed to the top of the movable frame. The output ends of the servo motors are connected to a lifting screw via a commutator. A lifting connecting plate is fitted onto the lifting screw via a screw sleeve. The two sides of the lifting connecting plate are slidably connected to the movable frame via vertical guide rails to ensure the stability of the lifting movement. The rotation of the lifting screw is driven by the servo motors via a commutator, causing the lifting connecting plate to move smoothly vertically. A coating blade is fixed to the lifting connecting plate. The coating blade is used to pick up liquid from the receiving tray and complete the coating action on the surface of the film or fabric.

[0006] Furthermore, a lifting cylinder is fixedly installed in the middle of the moving frame, and the output end of the lifting cylinder is connected to the slit coating head. The slit coating head has a loading chamber inside, and an injection port at the top, which communicates with the loading chamber for injecting the liquid to be coated. A slit extending from the middle to the bottom of the slit coating head is formed, and the liquid flows steadily out along the slit to the bottom opening under gravity. The lifting cylinder controls the vertical movement of the slit coating head, ensuring its bottom contacts the surface of the film or fabric, thereby achieving continuous coating.

[0007] Specifically, a coating roller is rotatably connected to one side of the moving frame via a linkage. The coating roller rests against the surface of the film or fabric on the vacuum adsorption plate under its own weight. When the coating device moves, the coating roller rolls accordingly, tightly adhering the film or fabric to the vacuum adsorption plate, improving coating uniformity. In addition, a left-right translation component is located below the vacuum adsorption plate, and its output end is connected to the base plate of the coating device for precise control of the left-right lateral movement of the coating device.

[0008] The first coating method of this utility model is spot coating, and the specific steps are as follows: S1, the left and right translation component drives the coating device to move above the receiving tray; S2, the servo motor drives the lifting screw to rotate through the commutator, so that the lifting connecting plate drives the coating blade to descend into the receiving tray to spot dip the liquid; S3, after the coating blade is reset, the left and right translation component drives the coating device to move to one end of the vacuum adsorption plate; S4, the servo motor drives the coating blade to descend to the surface of the film or fabric again; S5, the left and right translation component is activated, and the coating blade completes the coating action along the surface of the vacuum adsorption plate.

[0009] The second coating method is slot coating, with the following steps: S1, the left-right translation component drives the coating device to move to one end of the vacuum adsorption plate; S2, the lifting cylinder drives the slot coating head to descend to the surface of the film or fabric; S3, the left-right translation component is activated, and the slot coating head completes the coating action along the surface of the vacuum adsorption plate. This method omits the action of dipping liquid and is suitable for continuous coating scenarios.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the coordinated action of a servo motor, commutator, and lifting screw, the coating blade's lifting process achieves high precision and stability, meeting the precision coating needs of both laboratory and industrial production. The slit coating head design utilizes the liquid's own weight to ensure stable flow along the slit, guaranteeing uniform and continuous coating. The coating roller further enhances the adhesion of films or fabrics, preventing wrinkles or displacement during coating. The overall structure is compact, easy to operate, and suitable for various applications.

[0011] In summary, this utility model integrates two coating methods through the above technical solution, providing a high-precision and high-stability coating solution that significantly improves coating efficiency and quality, meeting the needs of different users. Attached Figure Description

Detailed Implementation

[0014] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings: like Figure 1-4 As shown, this embodiment provides a dual-purpose precision flatbed coating machine, combined with... Figures 1 to 4 The accompanying drawings illustrate the specific implementation of the device. This embodiment includes a vacuum adsorption plate 1, a coating device 2, a receiving tray 3, a moving frame 4, a servo motor 8, a commutator 9, a lifting screw 7, a slot coating head 15, a lifting cylinder 11, and a coating roller 5, among other main components. These components work together to achieve two different coating methods: spot coating and continuous slot coating, suitable for both laboratory and industrial production scenarios.

[0015] First, the structure and function of the vacuum adsorption plate 1 are introduced. The vacuum adsorption plate 1 is fixedly mounted on the machine base, and its surface is equipped with a negative pressure generating device. This device uses negative pressure to adsorb the film or fabric onto its surface, preventing displacement during coating. A receiving tray 3 is fixedly installed on one side of the vacuum adsorption plate 1. The receiving tray 3 stores the liquid to be coated, such as adhesive or surface treatment liquid, for the coating blade 12 to apply. The depth of the receiving tray 3 is moderate, ensuring that the coating blade 12 can accurately apply the liquid without affecting the coating effect due to insufficient liquid. Furthermore, a left-right translation component 6 is installed at the bottom of the vacuum adsorption plate 1. The output end of the left-right translation component 6 is connected to the base plate of the coating device 2, driving the coating device 2 to move linearly in the horizontal direction, achieving precise control of the coating action.

[0016] The coating device 2 is mounted on the vacuum adsorption plate 1 and can move laterally relative to the vacuum adsorption plate 1. The coating device 2 includes a moving frame 4, with a base plate at the bottom of the moving frame 4, which is connected to the output end of the left and right translation component 6. A pair of servo motors 8 are fixed on the top of the moving frame 4, and the output ends of the servo motors 8 are connected to the lifting screw 7 through a commutator 9. A lifting connecting plate 16 is fitted on the lifting screw 7 through a screw sleeve. The two sides of the lifting connecting plate 16 are slidably connected to the moving frame 4 through a vertical guide rail assembly 10 to ensure the stability of the lifting movement. The servo motors 8 drive the lifting screw 7 to rotate through the commutator 9, thereby driving the lifting connecting plate 16 to move smoothly in the vertical direction. A coating blade 12 is fixed on the lifting connecting plate 16. The coating blade 12 is used to pick up liquid from the receiving tray 3 and complete the coating action on the surface of the film or cloth.

[0017] A lifting cylinder 11 is fixedly installed in the middle of the movable frame 4, and the output end of the lifting cylinder 11 is connected to the slit coating head 15. The slit coating head 15 has a loading chamber 13 inside and an injection port 14 at the top, which communicates with the loading chamber 13 for injecting the liquid to be coated. A slit extending from the middle to the bottom is opened in the slit of the slit coating head 15, and the liquid flows steadily out of the slit to the bottom opening under the action of gravity. The lifting cylinder 11 drives the slit coating head 15 to rise and fall vertically, so that its bottom contacts the surface of the film or fabric, thereby achieving continuous coating. The design of the slit coating head 15 utilizes the liquid's own weight to flow steadily out of the slit, ensuring the uniformity and continuity of the coating.

[0018] A coating roller 5 is rotatably connected to one side of the movable frame 4 via a connecting rod. The coating roller 5 rests against the surface of the film or fabric on the vacuum adsorption plate 1 by its own weight. When the coating device 2 moves, the coating roller 5 rolls accordingly, tightly adhering the film or fabric to the vacuum adsorption plate 1, improving coating uniformity. In addition, a left-right translation component 6 is located below the vacuum adsorption plate 1, and its output end is connected to the base plate of the coating device 2 for precise control of the left-right lateral movement of the coating device 2.

[0019] The following details the operating principle and process of the first coating method, spot coating. S1: The left-right translation component 6 drives the coating device 2 to move above the receiving tray 3. The left-right translation component 6 is connected to the base plate of the coating device 2 via its output end, ensuring that the coating device 2 moves horizontally to the designated position. S2: The servo motor 8 drives the lifting screw 7 to rotate via the commutator 9, causing the lifting connecting plate 16 to lower the coating blade 12 into the receiving tray 3 to spot-dip the liquid. The servo motor 8 transmits power to the lifting screw 7 via the commutator 9. As the lifting screw 7 rotates, it drives the lifting connecting plate 16 to move smoothly vertically, ensuring that the coating blade 12 accurately spots the liquid. S3: After the coating blade 12 resets, the left-right translation component 6 drives the coating device 2 to one end of the vacuum adsorption plate 1. S4: The servo motor 8 again drives the coating blade 12 to descend to the surface of the film or fabric. S5: The left-right translation component 6 is activated, and the coating blade 12 completes the coating action along the surface of the vacuum adsorption plate 1. During this process, the coating blade 12 achieves high-precision and stable lifting motion through the coordinated action of the servo motor 8 and the lifting screw 7, meeting the precision coating needs in laboratories and industrial production.

[0020] The second coating method is slot coating, and its specific operating principle and process are as follows: S1, the left-right translation component 6 drives the coating device 2 to move to one end of the vacuum adsorption plate 1. The left-right translation component 6 is connected to the base plate of the coating device 2 through its output end, ensuring that the coating device 2 moves in a straight line in the horizontal direction to the designated position. S2, the lifting cylinder 11 drives the slot coating head 15 to descend to the surface of the film or fabric. The lifting cylinder 11 is connected to the slot coating head 15 through its output end, driving the slot coating head 15 to rise and fall in the vertical direction, so that its bottom contacts the surface of the film or fabric. S3, the left-right translation component 6 is activated, and the slot coating head 15 completes the coating action along the surface of the vacuum adsorption plate 1. This method omits the action of dipping the liquid, and is suitable for continuous coating scenarios. The design of the slot coating head 15 utilizes the weight of the liquid to flow steadily out along the slot, ensuring the uniformity and continuity of the coating.

[0021] In practical applications, this dual-purpose precision flatbed coating machine offers several advantages. The synergistic action of the servo motor 8, commutator 9, and lifting screw 7 ensures high precision and stability in the lifting process of the coating blade 12, meeting the precision coating needs of both laboratory and industrial production. The slit coating head 15 utilizes the liquid's own weight to ensure stable flow along the slit, guaranteeing uniform and continuous coating. The coating roller 5 further enhances the adhesion of films or fabrics, preventing wrinkles or displacement during coating. The overall structure is compact, easy to operate, and suitable for various application scenarios.

[0022] In summary, this utility model integrates two coating methods through the above technical solution, providing a high-precision and high-stability coating solution that significantly improves coating efficiency and quality, meeting the needs of different users.

[0023] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
