Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a coating equipment with adjustable coating thickness. Background Technology

[0002] In modern industrial manufacturing systems, the refined production in fields such as coatings, electronics, and packaging places stringent requirements on material surface treatment processes. As the core equipment for achieving uniform coating coverage, the precise control of coating thickness has become a key factor in determining product quality and performance. In the coating industry, the coating thickness of architectural coatings directly affects the durability and aesthetics of the wall surface. Coatings that are too thin are prone to cracking and fading, and cannot effectively resist wind and rain erosion. Coatings that are too thick will lead to slow drying, increased costs, and may cause defects such as sagging.

[0003] Existing coating equipment has many shortcomings in coating thickness adjustment. It usually relies on manual adjustment, which is not only cumbersome and inefficient, but also makes it difficult to guarantee the accuracy of adjustment, resulting in poor coating thickness consistency. In addition, the lack of a stable guiding and driving system during the adjustment process makes it easy for problems such as wobbling and deviation of the coating plate to occur, which further affects the coating quality and the service life of the equipment. Therefore, the above technical problems need to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coating device with adjustable coating thickness.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a coating device with adjustable coating thickness, comprising a placement plate and linear motors fixedly disposed on both sides of the placement plate. The upper end of the linear motor is provided with a horizontally disposed moving groove, and a moving seat is slidably connected in the moving groove. A column is vertically fixedly connected to the upper end of the moving seat. A guide groove is provided on the opposite side of the column, and a guide mechanism is provided between the columns. An adjustment mechanism is provided at the upper end of the guide mechanism, and a drive mechanism is provided on one side of the adjustment mechanism.

[0006] Preferably, a protective plate is fixedly connected to the upper end of the column, an L-shaped fixing frame is fixedly connected to one side of the inner side of the protective plate, a fixing block is fixedly connected to the lower end of the protective plate, and a rotating rod is horizontally rotatably connected between the fixing blocks.

[0007] Preferably, the drive mechanism includes a servo motor that is fixedly mounted on the inner side of an L-shaped mounting bracket by bolts, and a worm gear is fixedly connected to the output end of the servo motor. The worm gear meshes with a worm wheel on the outer periphery of the rotating rod.

[0008] Preferably, the rotating rod has evenly distributed locking teeth on the outer circumferential surface inside the fixed block.

[0009] Preferably, the adjustment mechanism includes a connecting plate that is snapped and fixed to the outside of the snapping teeth, a hinge plate that is hinged to the lower end of the connecting plate, and the other end of the hinge plate that is rotatably connected to the positioning block at the upper end of the scraper plate via a pin.

[0010] Preferably, the guiding mechanism includes upright plates fixedly connected to both sides of the upper end of the coating plate, the upright plates being tightly fitted to the side of the column, and two pulleys being equidistantly rotatably connected to the side of the upright plates, the pulleys being engaged in guide grooves on the side of the column.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a servo motor and a worm gear to cooperate with each other, which facilitates the height adjustment of the scraper, improves the consistency of the coating thickness, and thus achieves the function of ensuring the accuracy of adjustment. Furthermore, the pulley and the scraper cooperate with each other to ensure that there is no deviation during the adjustment process, which improves the stability of the equipment during adjustment. This improves the coating quality and the service life of the equipment, and ultimately solves the problems of poor coating thickness consistency and its impact on coating quality.

[0020] 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.

[0021] Example: See Figure 1-6 This utility model discloses an adjustable coating thickness scraping device, comprising a placement plate 1 and linear motors 2 fixedly mounted on both sides of the placement plate 1. A horizontally positioned moving groove 3 is provided at the upper end of the linear motors 2, and a moving seat 4 is slidably connected within the moving groove 3. A column 5 is vertically fixedly connected to the upper end of the moving seat 4. Guide grooves are provided on opposite sides of the columns 5, and a guide mechanism is provided between the columns 5. An adjustment mechanism is provided at the upper end of the guide mechanism, and a drive mechanism is provided on one side of the adjustment mechanism. The linear motors 2 and the columns 5 facilitate the lateral movement of the scraping mechanism, achieving full coverage of the coating area. A protective plate 6 is fixedly connected to the upper end of the columns 5, and an L-shaped fixing frame 14 is fixedly connected to one side of the inner side of the protective plate 6. Fixing blocks 7 are fixedly connected to the lower end of the protective plate 6, and a rotating rod 11 is horizontally rotatably connected between the fixing blocks 7. The protective plate 6 and the L-shaped fixing frame 14 facilitate the protection and fixation of the electrical components of the device. The drive mechanism includes components fixedly mounted on the L-shaped fixing frame 14 by bolts. The servo motor 12 is located inside the fixed bracket 14. The output end of the servo motor 12 is fixedly connected to the worm gear 13. The worm gear 13 meshes with the worm wheel on the outer periphery of the rotating rod 11. The worm gear 13 and the worm wheel facilitate the rotation of the rotating rod 11.

[0022] In this invention, the rotating rod 11 has evenly distributed locking teeth on its outer circumferential surface inside the fixed block 7. The locking teeth facilitate rotation, driving the rotating rod 11 to rotate, thereby driving the adjustment mechanism. The adjustment mechanism includes a connecting plate 8 fixed to the outside of the locking teeth. A hinge plate 9 is hinged to the lower end of the connecting plate 8. The other end of the hinge plate 9 is rotatably connected to the positioning block 10 at the upper end of the scraper plate 15 via a pin. The connection between the hinge plate 9 and the scraper plate 15 facilitates scraping the coating surface. The guide mechanism includes upright plates fixedly connected to both sides of the upper end of the scraper plate 15. The upright plates are tightly fitted to the side of the column 5. Two pulleys are equidistantly rotatably connected to the side of the upright plates. The pulleys are locked in the guide grooves on the side of the column 5. The connection between the pulleys and the upright plates facilitates adjustment of the distance between the scraper plate 15 and the coating surface.

[0023] Working Principle: When using this invention, after the equipment is started, the linear motor 2 begins to run, driving the moving seat 4 to slide horizontally within the moving groove 3, thereby moving the column 5 along a straight line and moving the entire coating equipment to a suitable working position. When it is necessary to adjust the coating thickness, the servo motor 12 on the L-shaped fixing frame 14 is started, driving the worm gear 13 to rotate through its output end. Since the worm gear 13 meshes with the worm wheel on the outer periphery of the rotating rod 11, it drives the rotating rod 11 to rotate between the fixing blocks 7. The locking teeth on the outer periphery of the rotating rod 11 located inside the fixing blocks 7 are evenly distributed. As the rotating rod 11 rotates, the locking teeth engage and fix the rotating rod 11. When the position of the connecting plate 8 changes, it drives the hinge plate 9 to move. The other end of the hinge plate 9 is rotatably connected to the positioning block 10 at the upper end of the scraper plate 15 through a pin, thereby changing the height of the scraper plate 15 and thus adjusting the coating thickness. The upright plates fixedly connected to both sides of the upper end of the scraper plate 15 are tightly fitted to the side of the column 5. Two pulleys equidistantly rotatably connected to the side of the upright plates are engaged in the guide groove on the side of the column 5. During the movement of the scraper plate 15, the pulleys roll in the guide groove to ensure that the scraper plate 15 moves smoothly along the predetermined direction, preventing the scraper plate 15 from deviating or shaking, and ensuring the uniformity and accuracy of the scraping.

[0024] 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.
