Description

Technical Field

[0001] This utility model relates to the technical field of building steel component processing equipment, specifically a building steel component coating equipment. Background Technology

[0002] As core load-bearing components of building projects, steel structural members are susceptible to damage during storage, transportation, and on-site construction. Factors such as rainwater erosion, industrial dust accumulation, corrosive media (e.g., salt, acids, and alkalis in the air), and mechanical abrasion can cause surface corrosion, coating damage, or structural damage. This not only reduces the mechanical properties and service life of the steel components but may also pose a threat to the overall structural safety of the building. Therefore, applying a high-strength protective film to the surface of steel structural members before they leave the factory is a crucial processing step to ensure surface quality and extend their service life.

[0003] Currently, the mainstream coating equipment for building steel components on the market generally adopts the following two pressing structures: The first is a rigid metal pressing roller. Although this type of structure has high structural strength, it cannot adapt to the small irregularities (such as welding spatter residue, surface processing texture), corner curvature, or irregular cross-sectional shapes commonly found on the surface of building steel components. During the pressing process, the film is prone to not adhering tightly to the surface of the steel component, resulting in air bubbles and wrinkles left under the film, or the film lifting at the corners of the steel component. Later, the protective film is prone to falling off from the defects, losing its protective function. The second is a simple airbag-type pressing roller. Although it has a certain degree of elasticity and adaptability, it has three major shortcomings. The problems are as follows: First, the connection between the airbag and the rotating shaft often uses a single-plane seal, which has poor sealing performance and is prone to gas leakage after long-term use, resulting in unstable airbag pressure and large fluctuations in pressing quality. Second, there is a lack of an effective overpressure protection mechanism. When the airbag is squeezed by the protruding parts of the steel components during the pressing process, the internal air pressure rises suddenly, which can easily cause the airbag to rupture, increasing equipment maintenance costs and downtime. Third, the pressing force adjustment relies on manual operation. The extension and retraction of the electric push rod are judged by experience, which makes it impossible to accurately control the pressing force. Too much pressing force will cause the protective film to rupture, while too little pressing force will result in insufficient film adhesion, making it difficult to meet the needs of large-scale, high-quality coating production. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a film coating equipment for building steel components, which solves the problems of poor compatibility and difficulty in controlling the pressing force, resulting in low film coating processing efficiency, low product qualification rate, and inability to meet usage requirements.

[0005] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A film coating device for building steel components includes a pressing roller body, which includes a rotating shaft and an elastic air bladder. Both ends of the elastic air bladder are connected to an end plate integrally set on the rotating shaft by fastening pressure rings. An inflation nozzle is installed on one end plate to facilitate quick connection with an external air source to inflate the elastic air bladder. A pressure relief valve is installed on the other end plate to facilitate venting when the air pressure inside the elastic air bladder exceeds a set value, thereby preventing damage to the elastic air bladder due to excessive air pressure. The elastic airbag overlap area on the end plate cooperates with the fastening pressure ring to form a clamping component for clamping the end of the airbag. The fastening pressure ring is fixedly connected to the end plate by bolts, which facilitates the stable clamping and fixing of the end of the elastic airbag on the rotating shaft. They cooperate to form a stable roller body. To ensure sealing, sealant is used to seal the bolt area. The end plate is integrally provided with a first annular raised seal at the contact point with the elastic airbag, and a second annular raised seal is integrally provided at the contact point with the fastening ring and the elastic airbag. Both the first annular raised seal and the second annular raised seal are tightly abutted against the elastic airbag, forming a stable sealing connection at the connection point to prevent gas leakage at the connection point and ensure stable use. After the elastic airbag is inflated, it forms a cylindrical roller on the rotating shaft, which can easily come into contact with the film attached to the surface of the building steel component and press the film to make the film stably attached to the surface of the building steel component. The end plate has a one-way air inlet valve installed in the inflation nozzle, and a protective cover is installed at the end located outside the elastic airbag to ensure stable inflation of the elastic airbag. The pressing roller is rotatably connected to the roller frame via a rotating shaft. The roller frame is mounted on the frame of the coating equipment via an electric push rod. The electric push rod can drive the pressing roller to move, so that the roller presses onto the building steel component. This facilitates stable installation on the coating equipment. The roller can move under the drive of the transmission mechanism on the coating equipment, thus allowing the pressing roller to move smoothly on the building steel component, so that the film is stably attached to the surface of the building steel component. The two ends of the roller frame are bent to form a bearing seat that matches the rotating shaft. The rotating shaft is rotatably connected to the bearing seat of the roller frame through a bearing, which facilitates the smooth rotation of the pressing roller on the roller frame, so as to stably complete the pressing of the film. The roller frame is also equipped with a controller, which is electrically connected to the electric push rod and a pressure sensor installed at the connection between the roller frame and the electric push rod. This allows for real-time detection of the pushing force exerted by the electric push rod on the pressing roller, thereby inferring the pressure exerted by the pressing roller on the membrane and the building steel components. The pressure data is then transmitted to the controller in real time, and the electric push rod is manipulated based on the pressure data to complete the adjustment of the pressing force.

[0006] (III) Beneficial Effects Compared with the prior art, this utility model provides a film coating equipment for building steel components, which has the following beneficial effects: This invention employs a core structure of an elastic airbag and inflatable molding for the pressing roller. The cylindrical roller formed by the inflated airbag possesses excellent elastic deformation capability. During the pressing process, the airbag can adaptively fit the surface of the building steel component according to its uneven shape, corner curvature, or irregular cross-section, tightly wrapping the surface of the steel component. This completely eliminates air bubbles and wrinkles between the film and the steel component, preventing the film from lifting at the corners and ensuring that the protective film adheres evenly and firmly to the surface of the steel component. The pressure sensor at the connection between the roller frame and the electric push rod can collect the pushing force data of the electric push rod on the pressing roller in real time and transmit the data to the controller. The controller automatically adjusts the extension and retraction of the electric push rod according to the preset pressing parameters, achieving precise control of the pressing force and improving production efficiency.

[0009] 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.

[0010] Example like Figure 1 , Figure 2 and Figure 3As shown in the figure, one embodiment of the present invention proposes a film coating device for building steel components, including a pressing roller body 1. The pressing roller body 1 includes a rotating shaft 101 and an elastic air bladder 103. Both ends of the elastic air bladder 103 are connected to the end plate 102 integrally set on the rotating shaft 101 by fastening pressure rings 104. An inflation nozzle 105 is installed on one end of the end plate 102 to facilitate quick connection with an external air source to inflate the elastic air bladder 103. A pressure relief valve 106 is installed on the other end of the end plate 102 to facilitate the release of air after the air pressure in the elastic air bladder 103 exceeds a set value, so as to avoid damage to the elastic air bladder 103 due to excessive air pressure. The overlapping area of ​​the elastic airbag 103 on the end plate 102 and the fastening pressure ring 104 cooperate to form a clamping member for clamping the end of the airbag. The fastening pressure ring 104 is fixedly connected to the end plate 102 by bolts, which facilitates the stable clamping and fixing of the end of the elastic airbag 103 to the rotating shaft 101, thereby forming a stable roller body. To ensure sealing, sealant is used to seal the bolt area. The end plate 102 and the elastic airbag 103 are integrally provided with a first annular raised seal 1021 at the contact point, and the fastening ring 104 and the elastic airbag 103 are integrally provided with a second annular raised seal 1041 at the contact point. The first annular raised seal 1021 and the second annular raised seal 1041 are both tightly abutted against the elastic airbag 103, forming a stable sealing connection at the connection point, preventing gas leakage at the connection point, and ensuring stable use. Among them, after the elastic airbag 103 is inflated, it forms a cylindrical roller on the rotating shaft 101, which facilitates contact with the film attached to the surface of the building steel component and presses the film, so that the film can be stably attached to the surface of the building steel component. The end plate 102 has an inflation nozzle 105 equipped with a one-way air inlet valve, and a protective cover is provided at one end outside the elastic airbag 103 to ensure stable inflation of the elastic airbag 103. The pressing roller 1 is rotatably connected to the roller frame 2 via the rotating shaft 101. The roller frame 2 is mounted on the frame of the coating equipment via the electric push rod 3. The electric push rod 3 can drive the pressing roller 1 to move, so that the roller presses onto the building steel component. This facilitates stable installation on the coating equipment. The roller 1 can move smoothly on the building steel component under the drive of the transmission mechanism on the coating equipment, so that the film is stably attached to the surface of the building steel component. The roller frame 2 is bent at both ends to form a bearing seat for the rotating shaft 101. The rotating shaft 101 is rotatably connected to the bearing seat of the roller frame 2 through a bearing, which facilitates the smooth rotation of the pressing roller 1 on the roller frame 2, so as to stably complete the pressing of the film. A controller 4 is also installed on the roller frame 2. The controller 4 is electrically connected to the electric push rod 3 and the pressure sensor installed at the connection between the roller frame 2 and the electric push rod 3. This allows for real-time detection of the pushing force of the electric push rod 3 on the pressing roller 1, thereby inferring the pressure of the pressing roller 1 on the film and the building steel components. The pressure data is then transmitted to the controller 4 in real time, and the electric push rod 3 is controlled according to the pressure data to complete the adjustment operation of the pressing force.

[0011] When coating building steel components, the building steel components are placed on the operating table of the equipment, and then the film is glued to the surface of the building steel components, so that the film is initially attached to the surface of the building steel components. Then it is conveyed to the pressing process position. The electric push rod 3 drives the pressing roller 1 to move and abut against the film on the surface of the building steel components. The controller 4 adjusts the extension and retraction of the electric push rod 3 according to the pressure data to ensure that the pressing force of the elastic air bag 103 of the pressing roller 1 is within an appropriate range to avoid damaging the film. As it is conveyed, the film is gradually pressed tightly onto the surface of the building steel components, so that the film is stably attached. During the process of the electric push rod 3 driving the elastic airbag 103 of the pressing roller 1 to press onto the building steel component, the elastic airbag 103 will deform appropriately according to the shape of the building steel component surface, and press tightly onto the building steel component surface, thereby improving the quality of membrane pressing. During the compression and deformation process of the elastic airbag 103, if the internal air pressure of the elastic airbag 103 exceeds the set safe pressure value, the pressure relief valve 106 opens to release the gas in the elastic airbag 103, so as to avoid damage to the elastic airbag 103 and ensure stable use.

[0012] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
