Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a device for controlling the uniformity of paint coating thickness on a backing plate. Background Technology

[0002] In the process of processing and producing boards, board coating machines are a commonly used piece of equipment. They are mainly used to coat the surface of boards with various coatings, such as topcoats, to achieve functions such as decoration and protection of the board surface. They are widely used in many fields such as furniture manufacturing and building decoration material production.

[0003] Currently, most coating machines use a scraper to smooth the coating during application to ensure uniform coating thickness on the board surface. Existing scrapers are typically horizontal. As the board moves along the conveyor belt and passes the scraper, the coating tends to accumulate on its surface due to the scraper's obstruction. As production continues, the accumulated coating on the scraper increases, not only affecting the scraper's smoothing effect but also causing coating to drip onto the board surface, resulting in uneven coating, defects, and severely impacting product quality.

[0004] The reason for this problem is that the structure of the horizontal scraper is relatively simple. During the scraping process, the horizontal scraper has a weak guiding effect on the paint, and cannot effectively guide excess paint to the appropriate position. At the same time, due to the lack of a timely cleaning and collection device for paint accumulation on the scraper, paint continues to accumulate on the scraper, ultimately affecting the coating effect. Therefore, we propose a backing plate topcoat thickness uniformity control device to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a device for controlling the uniformity of paint coating thickness on a backing plate, solving the problem that existing scrapers are typically horizontal structures. When the board moves on the conveyor belt and passes the scraper, the paint easily accumulates on the scraper surface due to the scraper's obstruction. As production continues, the accumulated paint on the scraper increases, not only affecting the scraper's normal smoothing effect but also causing paint to drip onto the board surface, resulting in uneven coating, defects, and seriously impacting product quality.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] This application provides a device for controlling the uniformity of paint coating thickness on a backing plate, solving the problem that existing scrapers are typically horizontal structures. When the board moves on the conveyor belt and passes the scraper, the paint tends to accumulate on the scraper surface due to the scraper's obstruction. As production continues, the accumulated paint on the scraper increases, not only affecting the scraper's smoothing effect but also causing paint to drip onto the board surface, resulting in uneven coating, defects, and seriously impacting product quality.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] This utility model provides, for example Figure 1-3 The device shown is for controlling the uniformity of paint coating thickness on the pad plate.

[0022] Example 1: Includes a machine body 1, a support frame 2 is provided on the machine body 1, and a leveling unit 3 is provided between the support frame 2 and the machine body 1. The leveling unit 3 includes a V-shaped scraper 31, a vertical adjustment component 32 and a waste collection component 33. The machine body 1 is equipped with a conveyor belt, and the opening direction of the V-shaped scraper 31 is opposite to the moving direction of the conveyor belt; the vertical adjustment component 32 is installed inside the support frame 2, and the vertical adjustment component 32 is drivenly connected to the V-shaped scraper 31. The vertical adjustment component 32 is used to drive the V-shaped scraper 31 to move vertically; the waste collection component 33 is installed inside the V-shaped scraper 31, and the waste collection component 33 is used to collect excess paint on the V-shaped scraper 31.

[0023] A liquid injection component 4 is provided on one side of the support frame 2, which is used to spray paint onto the pad. The vertical adjustment component 32 includes a connecting plate 321 and a slider 322; the connecting plate 321 is fixedly mounted on both sides of the connecting plate 321; the slider 322 is fixedly mounted on one side of the connecting plate 321. The vertical adjustment component 32 also includes a sliding groove 323 and a threaded rod 324; the sliding groove 323 is formed inside the support frame 2, and the slider 322 is slidably connected inside the sliding groove 323; the threaded rod 324 is rotatably connected to one side inside the support frame 2, and the threaded rod 324 is threadedly engaged with the slider 322. The vertical adjustment component 32 also includes a motor 325; the motor 325 is fixedly mounted inside the support frame 2, and the output shaft of the motor 325 is fixedly mounted to the threaded rod 324.

[0024] In this embodiment, the pad is placed on the conveyor belt of the machine body 1, and the liquid injection component 4 is activated to spray the coating evenly onto the surface of the pad.

[0025] When vertically adjusting the V-shaped scraper 31, the motor 325 is started. The output shaft of the motor 325 drives the threaded rod 324 to rotate. Since the threaded rod 324 is threadedly engaged with the slider 322, and the slider 322 is slidably connected in the groove 323 inside the support frame 2, the slider 322 will slide vertically in the groove 323. The slider 322 drives the V-shaped scraper 31 to move vertically through the connecting plate 321, thereby adjusting the V-shaped scraper 31 to a suitable height position. When the pad moves past the V-shaped scraper 31 with the conveyor belt, because the opening direction of the V-shaped scraper 31 is opposite to the direction of the conveyor belt, its V-shaped structure can guide the paint towards the middle of the scraper, so that the paint is more evenly distributed on the surface of the pad under the action of the scraper, effectively reducing the accumulation of paint on both sides of the scraper.

[0026] This utility model embodiment discloses a device for controlling the uniformity of paint coating thickness on a pad. More specifically, based on Embodiment 1, it is according to the appendix... Figure 1 , 4 As shown.

[0027] Example 2: Includes a machine body 1, a support frame 2 is provided on the machine body 1, and a leveling unit 3 is provided between the support frame 2 and the machine body 1.

[0029] In this embodiment, when the V-shaped scraper 31 is smoothing the paint, excess paint enters the suction pipe 332 through the feed port 331 inside the V-shaped scraper 31. The suction pipe 332 has an elastic structure, which can better adapt to the entry and flow of paint. The liquid pump 333 installed on the support frame 2 is started.
