Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of coating instrument, concretely relates to a spraying and doctoring integrated coating instrument for paint thickness detection. BACKGROUND
[0002] In the paint industry, accurate control of paint thickness is crucial for product quality. However, traditional paint coating methods often rely on manual operations, such as using brushes, rollers, or simple mechanical devices for spraying and doctoring. These methods are not only inefficient, but also difficult to achieve uniform distribution and accurate control of the paint.
[0003] With the advancement of technology, some semi-automatic coating equipment has appeared on the market, but these devices often have the following shortcomings:
[0004] Low degree of automation: These devices can usually only perform a single spraying or doctoring action, and require frequent manual adjustment of parameters and monitoring of the process, with low degree of automation. Manual operation not only increases labor intensity, but also may cause operation errors, affecting the uniformity and accuracy of the paint thickness.
[0005] Cannot adapt to different thickness of card board: Traditional coating equipment usually does not have a mechanism to adapt to different thickness of test board. This means that when replacing test boards of different thickness, the position of the equipment or the card board needs to be adjusted manually, which not only consumes time and effort, but also may introduce additional errors. Due to the lack of flexible adaptation mechanism, these devices cannot be widely used in test board detection of different specifications and thickness.
[0006] Cannot scan paint thickness in real time and accurately control thickness: Traditional coating equipment lacks the function of real-time monitoring of paint thickness. This means that during the coating process, the actual thickness of the paint cannot be accurately known, so the coating process cannot be accurately controlled. Due to the lack of real-time feedback mechanism, the thickness of the paint often cannot reach the expected uniformity and accuracy, resulting in unstable product quality.
[0007] Uneven thickness: Due to the above problems, traditional coating equipment often cannot guarantee the uniformity of paint thickness. This may cause problems such as uneven thickness, color difference on the product surface, affecting the appearance and performance of the product. INVENTION CONTENTS
[0008] The utility model aims at providing a spraying and doctoring integrated coating instrument for paint thickness detection to solve the technical defects pointed out in the background art.
[0009] To solve the above technical problems, the utility model adopts the following technical scheme:
[0010] A spraying and scraping integrated coating instrument for paint thickness detection, comprising a base, a base horizontally arranged on the base, and a clamping plate detachably arranged on the top surface of the base, a clamping space for clamping a test plate being formed between the lower surface of the clamping plate and the upper surface of the base, a hollow opening for spraying and scraping being formed in the middle of the clamping plate, and a moving scraping mechanism being arranged above the hollow opening and capable of moving leftward and rightward and upward and downward to perform spraying and scraping actions on the test plate.
[0011] Further, the moving scraping mechanism comprises a bridge and bridge supports arranged on the front and back sides of the bridge, the front and back sides of the base being horizontally symmetrically provided with guide rails, the inner sides of the bridge supports being slidably guided by the guide rails, and the bottom of the bridge being provided with a scraping plate and a spray head for spraying raw materials, the spray head being directed downward, and the scraping plate being capable of extending into the hollow opening to perform a scraping action on the test plate sprayed with raw materials.
[0012] Further, the bridge supports are internally provided with a driving mechanism for driving the bridge to move upward and downward to adapt to clamping plates of different thicknesses, and the bridge supports are capable of sliding along the guide rails in a manual or automatic manner.
[0013] Further, the side of the base is provided with a pump body for pumping raw materials, and the pump body is connected to the spray head on the bridge through a conveying hose.

[0016] Compared with the prior art, the spraying and scraping integrated coating instrument has the following beneficial effects:
[0017] The spraying and scraping integrated coating instrument pumps raw materials to the spray head through the pump body, and the spray head sprays the test plate clamped in the clamping space under the driving of the moving scraping mechanism. Then, the scraping plate extends into the hollow opening to scrape the sprayed raw materials and form a uniform coating layer. The driving mechanism in the bridge supports can adjust the height of the bridge to adapt to clamping plates of different thicknesses. Meanwhile, the infrared probes on the periphery of the base can real-time scan the thickness of the coating layer to ensure the quality of the coating layer.

The coating instrument integrates spraying and scraping, is easy to operate, and has good coating uniformity. The real-time scanning function of the infrared probes ensures the accurate control of the thickness of the coating layer and improves the coating efficiency and quality. The height-adjustable design of the bridge makes the coating instrument applicable to clamping plates of different thicknesses, and enhances the versatility and flexibility of the equipment.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0025] like Figs. 1-2 As shown, a spray-and-scrape coating integrated coating instrument for coating thickness detection includes a base 1, a base 2 horizontally arranged on the base 1, and a clamping plate 3 detachably arranged on the top surface of the base 2. A clamping space for holding a test plate 4 is formed between the lower surface of the clamping plate 3 and the upper surface of the base 2. A hollow opening 4 for spraying and scraping is formed in the middle of the clamping plate 3. A movable scraper mechanism that can move left and right and up and down to perform spraying and scraping actions on the test plate 4 is arranged directly above the hollow opening 4.
[0026] This invention proposes an integrated spraying and scraping coating instrument for coating thickness detection. It comprises a base 1, a base 2, a clamping plate 3, a test plate 4, and a moving scraper mechanism. In use, the test plate 4 is placed on the work position of the base 2, and the clamping plate 3 presses it onto the test plate 4 to clamp and fix it. At this time, the moving scraper mechanism feeds or sprays material through the cutout opening 4. After feeding or spraying, the moving scraper mechanism moves up and down to an appropriate position, and then moves left and right to scrape the material evenly. This invention has a simple structure, high degree of automation, and achieves spraying and scraping of the test plate 4, facilitating coating thickness detection and demonstrating high practicality.
[0027] Specifically, as shown in the figure, the movable scraper mechanism includes a bridge frame 8 and bridge supports 7 arranged on the front and rear sides of the bridge frame 8. Guide rails 9 are horizontally symmetrically arranged on the front and rear sides of the base 2. The inner side of the bridge supports 7 slides and guides with the guide rails 9. A scraper and a nozzle for spraying raw materials are provided at the bottom of the bridge frame 8. The nozzle faces downwards, and the scraper can extend into the hollow opening 4 to smooth the test plate 4 coated with raw materials. A drive mechanism is provided inside the bridge supports 7 to drive the bridge frame 8 to move up and down to adapt to plates 3 of different thicknesses. The bridge supports 7 slide along the guide rails 9 manually or automatically.
[0028] When the test panel 4 needs to be sprayed and scraped, the drive mechanism is activated, causing the bridge support 7 to slide horizontally along the guide rail 9. The sliding guide cooperation between the bridge support 7 and the guide rail 9 ensures stable horizontal movement of the moving scraper mechanism. The cable tray 8 moves together with the bridge support 7, driving the scraper and nozzle to perform spraying and scraping actions above the test panel.
[0029] To accommodate test plates 3 of varying thicknesses, the bridge support 7 is equipped with a drive mechanism (such as a cylinder or electric push rod) to drive the bridge frame 8 to move up and down. By adjusting the height of the bridge frame 8, the appropriate distance between the scraper and nozzle and the test plate can be ensured, thus accommodating test plates of different thicknesses.
[0030] The specific structure of the drive mechanism is not described in detail, but it may include a motor, transmission belt, lead screw, cylinder, electric push rod, etc. All related structures that can realize the movement function are within the protection scope of this utility model.
[0031] Drive mechanisms can be implemented through manual control (such as knobs, handles, etc.) or automatic control (such as sensors, PLC controllers, etc.). Manual control is typically used for simple adjustments or debugging, while automatic control is used to achieve more precise and stable motion control.
[0032] During the horizontal movement of the moving scraper mechanism, the nozzle sprays the raw material onto the test panel. Parameters such as spray volume, spray speed, and spray pattern can be adjusted according to factors such as the type of paint, the material of the test panel, and the required coating thickness. After spraying, the scraper extends into the hollow opening 4 of the clamping plate 3 to smooth the paint-coated test panel. The scraper, through its own rigidity and contact force with the test panel surface, smooths the paint to the required thickness and uniformity.
[0033] Specifically, as shown in the figure, a pump body 10 for extracting raw materials is provided on the side of the base 1, and the pump body 10 is connected to the nozzle on the bridge frame 8 through a conveying hose 11.
[0034] Specifically, as shown in the figure, several infrared probes 13 for real-time scanning of coating thickness are erected on the periphery of the base 1 via support rods 12.
[0035] While the moving scraper mechanism performs spraying and scraping, the infrared probe 13 begins to scan the coating thickness in real time. The infrared probe 13 measures the height or thickness of the coating surface by emitting infrared light and receiving reflected light. The infrared probe 13 transmits the measured coating thickness data to the control system, which receives the data and compares it with a preset coating thickness. If the measured coating thickness does not reach the preset value, the control system sends a signal to the moving scraper mechanism, instructing it to continue spraying, feeding, and scraping operations. The control system also adjusts parameters such as the spray volume of the nozzle and the scraping force of the scraper based on the measured coating thickness data to ensure the uniformity and accuracy of the coating thickness.
[0036] Specifically, as shown in the figure, the base 2 is provided with a plurality of fixing holes 6, and the card plate 3 is provided with corresponding positioning holes. The positioning holes and fixing holes 6 are fixed together by screws.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
