[0002] As is well known, a coating spraying equipment for decorative panels in engineering construction is a mechanical device specifically designed for coating operations on decorative panels in the field of engineering construction. Its purpose is to cover the surface of the decorative panels with coatings to achieve decorative and protective effects.

[0003] Before applying paint to existing professional decorative panels, the surface of the panels must be cleaned to ensure that dust is completely removed. Currently, most of these devices use brushes on cleaning rollers for this purpose. However, when dealing with smooth panels, the brushes cannot adhere tightly to the smooth surface, leaving some dust residue that cannot be completely removed. This significantly reduces the cleaning effect and consequently affects the quality of subsequent paint application, potentially leading to issues such as reduced coating adhesion and uneven surfaces.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4A coating spraying device for decorative panels used in engineering construction includes a housing 1, a cover plate 2, a cabinet 5, a clamping mechanism 7, and a cleaning mechanism 8. The cover plate 2 is connected to the top of the housing 1 by a third bolt 23. A feeding assembly 3 is provided on one side of the top of the cover plate 2, and a spraying assembly 4 is provided at the center of the top of the cover plate 2. The cabinet 5 is connected to the bottom of one side of the housing 1, and a switch door 6 is provided on the other side of the cabinet 5. The switch door 6 is hinged to the cabinet 5. The clamping mechanism 7 is disposed on the cabinet 5. The cleaning mechanism 8 includes a slide groove 9, a sliding frame 10, a first bolt 11, a first cleaning assembly 12, and a second cleaning assembly 18. The slide groove 9 is formed on the cabinet 5, and the sliding frame 10 extends into the slide groove 9. In the first cleaning assembly 12, the first cleaning component 12 is connected to the sliding frame 10 via the first bolt 11. The first cleaning component 12 includes a first mounting block 13, a first electric push rod 14, a connecting plate 15, a brush plate 16, and a second bolt 17. One end of the first electric push rod 14 is connected to the first mounting block 13, and the other end of the first electric push rod 14 is connected to the connecting plate 15. The brush plate 16 is connected to the connecting plate 15 via the second bolt 17. The second cleaning component 18 includes a second mounting block 19, a second electric push rod 20, and a cleaning roller assembly 21. One end of the second electric push rod 20 is connected to the second mounting block 19, and the other end of the second electric push rod 20 is connected to the cleaning roller assembly 21.

[0023] Working principle: Before starting the equipment, it must be placed in the designated location, and the entire equipment is stably supported by the housing 1 and cabinet 5. Then, connect to the external mains power to supply power to the equipment. After the preparation work is completed, according to... Figure 1 As shown, the clamping mechanism 7 is activated to clamp the board to be sprayed. The clamping mechanism 7 consists of a guide groove, two sliders, a bidirectional threaded rod, two clamping blocks and a motor. After the motor is started, it drives the bidirectional threaded rod to rotate. The two sliders that are threaded to the bidirectional threaded rod will move relative to each other, thereby driving the two clamping blocks to firmly fix the board. Then, the specified paint that matches the characteristics of the board is poured into the box 1 through the feeding component 3. The specific type of paint needs to be determined according to the board. After the paint is added, the board is cleaned. If the board surface is smooth and without ridges, the first electric push rod 14 on the first mounting block 13 is activated, which drives the brush plate 16 on the connecting plate 15 to descend and contact the board. Then, the sliding frame 10 is pushed to slide in the sliding groove 9, so that the brush plate 16 can fully wipe the surface of the board and remove dust. Since the brush plate 16 is connected to the connecting plate 15 by the second bolt 17, it is easy to purchase a new brush plate from the manufacturer to replace it after the brush plate 16 is worn after long-term use. The brush plate 16 is equipped with non-woven fabric, which is convenient for cleaning dust.

[0024] If the surface of the board has raised texture, the cleaning component needs to be replaced. The worker holds the first mounting block 13 and uses an external screwdriver to unscrew the first bolt 11 to separate the first cleaning component 12 from the sliding frame 10. Then, the first bolt 11 is used to connect the second mounting block 19 to the sliding frame 10. After installation, the cleaning roller assembly 21 is started. The cleaning roller assembly 21 includes a frame, bearings, cleaning rollers and a motor. After the motor is started, it drives the cleaning roller connected to the frame through the bearings to rotate. The cleaning roller is equipped with bristles. At the same time, the second electric push rod 20 is started, which drives the cleaning roller to descend and contact the board, pushing the sliding frame 10 to move in the slide groove 9 to complete the cleaning work on the board with raised texture.

[0025] After the board is cleaned, the unused cleaning components (first cleaning component 12 or second cleaning component 18) are placed in the cabinet 5, and the switch door 6 is closed. Then, the sliding frame 10 is pushed to separate it from the slide groove 9. The cleaning components on the sliding frame 10 are removed and placed around the equipment to prevent paint from contaminating the cleaning components during the spraying process. After that, the worker starts the spraying component 4 to spray the board with paint. After the spraying work is completed, the clamping mechanism 7 is started again to release the board. The worker takes it out and sends it to the next process. If it is necessary to spray the reverse side of the board, the worker must wait for the sprayed side to dry and cure before controlling the clamping mechanism 7 to stop clamping the board. The worker flips the board over and fixes it with the clamping mechanism 7. Then, the above operation is repeated. When spraying the next board, the sliding frame 10 is first connected to the slide groove 9, and then each operation is completed in sequence. It should be noted that the same cleaning component should be used for the same batch of boards to avoid affecting work efficiency due to frequent changes in cleaning components.

[0026] After the equipment is used up, in order to facilitate the storage and protection of the cleaning components, the first cleaning component 12 and the second cleaning component 18 are placed in the cabinet 5. The cabinet 5 has ample internal space and is equipped with a rubber layer, which can effectively prevent the cleaning components from being damaged by collision with the inner wall of the cabinet 5. Then, the switch door 6 is closed. The switch door 6 adopts conventional technology on the market and includes the door body and door lock structure, which will not be described in detail here.

[0027] In the equipment, to achieve precise adjustment of the lifting stroke of the cleaning component by the first electric push rod 14 and the second electric push rod 20 to adapt to the cleaning needs of materials of different thicknesses, displacement sensors and pressure sensors are specially installed. The displacement sensors are firmly connected to the telescopic part of the electric push rods and can measure the stroke distance of the electric push rods in real time and accurately. The measured displacement data is quickly transmitted to the control device on the first and second mounting blocks through a specific transmission line. Before the cleaning work begins, the operator only needs to set the accurate descent height of the cleaning component on the control device according to the actual thickness of the material. The control device can then accurately judge the operating status of the electric push rod based on the real-time data fed back by the displacement sensor. When the electric push rod reaches the preset height, the control device will immediately issue a command to stop its operation, thereby accurately controlling the cleaning component to descend to the appropriate position. The pressure sensor is responsible for monitoring the contact between the cleaning component and the material. During the descent of the cleaning component towards the material, the pressure sensor is constantly on standby to detect surface contact pressure changes. Upon contact with the material, it sensitively senses these pressure changes and quickly transmits the signal to the control device. Operators can pre-set appropriate pressure thresholds in the control device based on the material characteristics and specific cleaning requirements. When the pressure detected by the sensor reaches this threshold, the control device immediately responds, stopping the electric push rod from descending. This prevents damage to the material due to excessive pressure while ensuring sufficient contact between the cleaning component and the material, guaranteeing the quality of the cleaning work. The displacement and pressure sensors work together to create a comprehensive and precise control system. This system accurately adjusts the stroke of the first electric push rod 14 and the second electric push rod 20, greatly improving the equipment's adaptability to cleaning materials of different thicknesses, reducing the risk of collision damage between the cleaning component and the material, and providing strong support for the stable and efficient operation of the equipment.

[0028] When the paint in box 1 is used up and needs to be replaced with a different paint, the staff uses an external screwdriver to unscrew the third bolt 23, separating the cover plate 2 from box 1. At this time, the bottom opening of box 1 is exposed, and external cleaning equipment such as rinsing equipment and cleaning brushes are used to clean box 1 and cover plate 2 to prevent residual paint in the box from mixing with the paint to be used next time, which would affect the quality of the final product.

[0029] The tank 1 is equipped with a liquid level sensor or a weight sensor. The sensor signals are connected to the controller 22. The liquid level sensor can monitor the liquid level of the paint in real time, while the weight sensor calculates the remaining amount of paint by measuring the total weight change of the tank and the paint. When the remaining amount of paint is lower than the set value, the controller 22 issues an alarm to remind the operator to add paint in time.

[0030] To ensure the health of staff and the normal operation of equipment, staff must wear professional protective clothing when operating the equipment. The protective clothing should have good impermeability to effectively block the adhesion of paint droplets, prevent staff from coming into contact with the paint, and reduce health risks. At the same time, the equipment should be cleaned and inspected regularly, especially cleaning components and electrical parts, and removing any adhering paint in a timely manner to ensure that the equipment is in good working condition and reduce equipment failures caused by paint contamination.

[0031] In this structure, the spraying assembly consists of a nozzle, spray pipe, pressure pump, flow control valve, and atomizing device. The nozzle is one of the core components of the spraying assembly, and its design directly affects the coating effect. The shape and nozzle distribution of the nozzle are carefully designed. Depending on different spraying needs, fan-shaped nozzles, circular nozzles, etc., can be selected. Fan-shaped nozzles are suitable for spraying large areas of panels, enabling the coating to cover the panel surface evenly; circular nozzles are more suitable for concentrated spraying of local areas. The size and number of nozzles are also precisely calculated to ensure that the coating is sprayed at the appropriate flow rate and speed. The spray pipe connects the storage tank and the nozzle, responsible for transporting the paint. To ensure smooth paint flow within the pipe, it is made of a corrosion-resistant material with a smooth inner wall, reducing paint residue and clogging. The pipe diameter is selected based on the paint flow rate and pressure to avoid excessive pressure loss or insufficient flow. A pressure pump is installed on the spray pipe to provide sufficient pressure for the paint to pass smoothly through the nozzle. The pressure pump is adjustable, allowing operators to adjust the pressure according to the material of the substrate, the viscosity of the paint, and the spraying conditions. The process requires adjusting the pressure within a certain range to ensure the coating adheres to the board surface with appropriate atomization and spraying force. A flow control valve, installed between the pressure pump and the nozzle, precisely controls the coating flow rate. By adjusting the flow control valve, the amount of coating can be flexibly adjusted according to the size, shape, and spraying area of ​​the board, avoiding coating waste or uneven spraying. For example, when spraying smaller boards or intricate patterns, the coating flow rate can be reduced; while when spraying large areas, the flow rate can be appropriately increased. The atomization device is a crucial component of the spraying assembly. It disperses the coating into tiny droplets, ensuring uniform adhesion to the board surface. The atomization device employs advanced technologies such as air atomization and pressure atomization, mixing compressed air or high-pressure liquid with the coating to form fine mist particles at the nozzle exit. Simultaneously, the atomization device can adjust the droplet size and distribution to meet different spraying requirements. For example, for smooth boards, smaller droplets are needed to ensure coating smoothness; while for rough boards, the droplet size can be appropriately increased to improve coating adhesion.

[0032] In addition, to reduce wear between equipment components and decrease the coefficient of friction, all surfaces of the parts in contact with each other are coated with a ceramic coating, effectively extending the service life of the equipment and ensuring stable operation.

[0033] In actual use, all operators of this equipment are rigorously trained professionals. The training is comprehensive, including the equipment's working principles, operating procedures, safety precautions, and emergency response methods. Through systematic training, operators are very familiar with the equipment's components and functions, possess proficient operating skills, and can accurately complete various tasks. When replacing cleaning components, professionals, with their solid skills, can quickly and orderly complete operations such as holding the first mounting block and tightening bolts. They are familiar with the operating space, rationally plan their actions, and reduce operating time. Moreover, long-term practice has allowed them to accumulate rich experience and adjust their operating methods in a timely manner according to the equipment's operating status. For example, when replacing cleaning components on different types of boards, they can quickly select the appropriate process and tools to improve efficiency. Therefore, under the operation of professionals, the efficiency of this equipment will not be affected by low operator proficiency, effectively ensuring the efficient and stable operation of the equipment.

[0034] In this structure, the bristles on the cleaning roller of the cleaning roller assembly 21 are made of bristle materials with smooth surfaces or special molecular structures, such as polytetrafluoroethylene bristles. These bristles have low surface friction, making it difficult for dust and impurities to adhere to or entangle. Thus, when cleaning textured boards, even if dust comes into contact with the bristles, it will be difficult to entangle due to the smooth surface and will slide directly off the bristles. The bristles are arranged in an interlaced manner, which increases the gap between the bristles, allowing impurities more space to pass through and reducing the possibility of entanglement.

[0035] In practical use, it was found that the original equipment had certain shortcomings in terms of ease of operation. To effectively solve this problem, in the design of this embodiment, a controller 22 is added to the front of the housing 1. The controller 22 is electrically connected to the spraying assembly 4 and the clamping mechanism 7 through the circuit. With the help of the controller 22, the operator can conveniently control the spraying assembly 4 and the clamping mechanism 7 in a centralized manner. When performing the coating operation on the board, the operator no longer needs to operate the spraying assembly 4 and the clamping mechanism 7 separately. He only needs to perform a simple operation on the controller 22 to accurately control the clamping action of the clamping mechanism 7 on the board and the coating operation of the spraying assembly 4, which significantly improves the convenience and efficiency of the equipment operation.

[0036] In this embodiment, to effectively improve the stability and reliability of the connection between the various components of the equipment, multiple first bolts 11, second bolts 17, and third bolts 23 are set at the relevant connection points through rigorous design. The setting of multiple first bolts 11 strengthens the connection between the sliding frame 10 and the first cleaning component 12, ensuring that the two can maintain a tight connection even when subjected to vibration or external force during equipment operation, avoiding loosening or falling off, thereby ensuring the smooth progress of the cleaning work. Similarly, the use of multiple second bolts 17 enhances the connection strength between the brush plate 16 and the connecting plate 15, enabling the brush plate 16 to function stably during the wiping of the board and extend its service life. The design of multiple third bolts 23 effectively ensures the stable connection between the cover plate 2 and the housing 1, preventing the cover plate 2 from shifting or shaking during equipment operation, paint addition, or cleaning, thereby maintaining the stability of the overall structure of the equipment and providing a solid guarantee for the efficient operation of the equipment.

[0037] In the design process of this embodiment, the important impact of the sliding stability of the sliding frame 10 in the slide groove 9 on the overall performance of the equipment was fully considered. In order to ensure that the sliding frame 10 can slide smoothly and steadily in the slide groove 9 and avoid adverse phenomena such as shaking and jamming, the part of the sliding frame 10 that extends into the slide groove 9 was specially designed to make its size and shape highly consistent with the slide groove 9. That is, the part of the sliding frame 10 that extends into the slide groove 9 is completely matched with the slide groove 9. This design optimization greatly improves the stability of the sliding frame 10 during the sliding process, effectively reduces the problems such as poor cleaning effect and accelerated equipment wear that may be caused by unstable sliding, and thus ensures the reliability and efficiency of equipment operation.

[0038] In practical application scenarios, through testing and analysis, it was found that the original housing 1 and cabinet 5, due to their insufficient strength, have a high risk of breakage during long-term use. This not only affects the normal operation of the equipment but may also lead to safety hazards, increase maintenance costs, and reduce downtime. To effectively solve this problem, in the optimized design of this embodiment, the manufacturing materials of housing 1 and cabinet 5 were reselected. After multiple rounds of comparison and testing, it was finally decided to use alloy steel to manufacture housing 1 and cabinet 5. Alloy steel has excellent properties such as high strength and high toughness. Compared with the original material, it can significantly improve the structural strength of housing 1 and cabinet 5, effectively resist the action of various external forces during long-term use, greatly reduce the risk of breakage, extend the overall service life of the equipment, and ensure the stability and reliability of the equipment during long-term operation, providing a solid hardware foundation for the coating spraying operation of decorative panels in engineering construction.

[0039] The size and shape of all components in this structure are not specifically limited here and need to be produced according to the actual situation. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the power supply are common knowledge in this field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and wiring layout will not be explained in detail here.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
