Description

Technical Field

[0001] This utility model belongs to the field of rock wool processing technology, specifically relating to an automatic film coating device for rock wool rolls. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Rock wool felt, a common rock wool product, is frequently used for sound insulation in industrial facilities and residential spaces. Its soft and easily cut material allows construction workers to easily cut it to the required size and install it quickly, significantly improving overall construction efficiency, shortening the construction period, and effectively reducing labor costs and project expenses. Rock wool felt units are mostly between 4 and 6 meters in length. Due to its softness and low density, it is currently mostly packaged in rolls for easy transportation and storage, ensuring the product remains neat and compact during transport.

[0004] Due to the softness and low density of rock wool felt, different layers are prone to sticking together during the rolling process. This can lead to product damage or difficulty in separation. A protective film needs to be applied to the surface of the rock wool felt to prevent sticking and maintain surface integrity. However, during the protective film application process, the rough surface of the rock wool (sharp fiber burrs) and the shape of the roll often result in the protective film being punctured by the rock wool fibers, or incomplete wrapping / loosening and rebounding. Furthermore, most rock wool rolls are rolled from the bottom up inwards, a relatively easy method to implement. Therefore, a bottom-covering method is used to ensure that the outermost layer is also covered with a film after rolling, preventing the roll from unraveling. However, this covering method has a low degree of automation. Utility Model Content

[0005] The purpose of this invention is to provide an automatic film covering device for rock wool rolls, which can solve at least one of the above-mentioned technical problems and achieve complete automation of the film covering process.

[0006] To achieve the above objectives, one or more embodiments of this utility model provide an automatic film coating device for rock wool rolls, comprising a protective film, a guide roller group, and a conveying mechanism arranged sequentially along the conveying direction. The conveying mechanism includes at least two sets of conveying components arranged at intervals. An adsorption component and a film pressing and cutting component are arranged between adjacent conveying components. The adsorption component is arranged near the guide roller group and includes a film suction tube and a film blowing tube. The film suction tube is arranged between the film pressing and cutting component and the film blowing tube. The film pressing and cutting component includes a bracket and a heating and sealing knife. A telescopic cylinder is arranged on the bracket, and the heating and sealing knife is hinged to the piston rod of the cylinder.

[0007] Furthermore, the suction tube has a square cross-section, and the upper surface of the suction tube has evenly distributed adsorption holes; the blown film tube has a circular cross-section, and the upper surface of the blown film tube is provided with airflow holes; the axis of the airflow holes is inclined at an acute angle to the conveying direction.

[0008] Furthermore, a silicone pad is also provided on the bracket, which is located directly below the heating and sealing blade. The installation height of the silicone pad, the suction tube, and the blown film tube is consistent with the height of the conveying assembly.

[0009] Furthermore, the heated sealing and cutting knife is also equipped with a pressure plate and a brush, and the pressure plate is in contact with the upper surface of the suction tube.

[0010] Furthermore, the bristle tips of the brush are lower than the bottom surface of the pressure plate.

[0011] Furthermore, the cutting edge length of the heated sealing cutter is greater than the width of the protective film.

[0012] Furthermore, on adjacent conveying components of the conveying mechanism, an inlet photoelectric detector and an outlet photoelectric detector are provided along the conveying direction.

[0013] Furthermore, the inlet photoelectric detector and the outlet photoelectric detector are respectively installed on both sides of the heating and sealing blade.

[0014] Furthermore, the guide roller assembly comprises at least three parallel cylindrical rollers, with the axes of each roller arranged parallel to each other on the same horizontal plane.

[0015] Furthermore, the suction tube is connected to a negative pressure generating device via a pipe; the blown film tube is connected to a compressed air source via a pipe.

[0016] The beneficial effects of one or more of the above technical solutions are as follows: This invention utilizes the coordinated operation of an adsorption component and a film-pressing and cutting component. The airflow holes in the blown film tube of the adsorption component are inclined to improve the airflow impact effect, allowing the film to be quickly attached to the front of the rock wool felt. The film moves forward with the rock wool felt, and at this time the film is located at the bottom of the rock wool felt. The suction tube uses a negative pressure system to fix the protective film and prevent the protective film from shifting during the transportation process after being wrapped with the rock wool felt. The film-pressing and cutting component cuts the protective film to ensure neat edges and complete the wrapping process.

[0017] The suction tube uses negative pressure to adsorb the lower surface of the membrane material, and together with the pressing plate, it compacts the membrane material. This dual action ensures that the membrane layer is tightly attached to the surface of the rolled felt, effectively solving the problems of loosening and rebound caused by insufficient wrapping in traditional lamination.

[0021] like Figures 1 to 3 As shown, this embodiment provides an automatic film covering device for rock wool rolls, including a protective film 1, a guide roller group 2, and a conveying mechanism 3 arranged sequentially along the conveying direction.

[0022] like Figure 1 As shown, the conveying mechanism 3 includes at least two sets of conveying components arranged at intervals. An adsorption component and a film cutting component are arranged between adjacent conveying components. The adsorption component is arranged on the side close to the guide roller group 2.

[0023] Specifically, on adjacent conveying components of the conveying mechanism 3, along the conveying direction of the rock wool felt 13, an inlet photoelectric detector 10 and an outlet photoelectric detector 11 are fixedly installed. Both the inlet photoelectric detector 10 and the outlet photoelectric detector 11 are located on the side of the conveying component and are used to detect the position of the rock wool felt 13 on the conveying component. The inlet photoelectric detector 10 and the outlet photoelectric detector 11 are respectively installed on the feed side and the discharge side of the film cutting component. The two are symmetrically arranged to ensure coordinated operation. The guide roller group 2 consists of at least three cylindrical rollers with the same diameter. All roller axes are located on the same horizontal plane and are parallel to each other to provide stable guidance and support for the protective film 1.

[0024] like Figure 2 and Figure 3As shown, the adsorption assembly includes a film suction tube 5 and a film blowing tube 4. The film suction tube 5 is disposed between the film pressing and cutting assembly and the film blowing tube 4. The adsorption assembly is connected to the two side support frames 14 of the conveying assembly by bolts. The support frames 14 are fixedly connected to the conveying assembly.

[0025] Specifically, the upper surface of the blown film tube 4 is provided with at least eight airflow holes. The axis of the airflow holes is inclined at an acute angle to the conveying direction of the protective film 1, which can enhance the impact effect of the airflow and facilitate the uniform blowing of compressed air from the inside of the tube to assist the protective film 1 in attaching to the front of the rock wool felt 13. One end of the blown film tube 4 is closed, and the other end is connected to the compressed air source through a pipe to ensure a stable air supply and improve the efficiency of the protective film 1 attaching to the rock wool felt 13. The lower surface of the blown film tube 4 is directly connected to the compressed air source through a pipe to provide continuous airflow power. The overall cross-section of the blown film tube 4 is circular, which is conducive to the uniform flow and diffusion of airflow in the tube cavity.

[0026] The cross-section of the suction tube 5 is square, and at least eight adsorption holes are evenly distributed on its upper surface. One end of the suction tube 5 is closed, and the other end is connected to a negative pressure generating device through a pipe. The device generates a stable negative pressure environment inside the tube, which is used to adsorb the lower surface of the protective film 1 through negative pressure. The internal negative pressure is connected to the outside through the adsorption holes to form suction to fix the position of the protective film 1. The square cross-section design of the suction tube 5 helps the adsorption holes to be evenly distributed on the plane, enhancing the adsorption effect.

[0027] like Figure 2 and Figure 4 As shown, the film pressing and cutting assembly includes a bracket and a heating and sealing blade 7. A telescopic cylinder 12 is provided on the top of the bracket, which is used to drive the heating and sealing blade 7 to reciprocate up and down.

[0028] Specifically, the heated sealing and cutting blade 7 is connected to the piston rod of the cylinder via a hinge, enabling flexible angle adjustment and precise positioning. A silicone pad 9 is also installed on the support, fixed directly below the heated sealing and cutting blade 7, providing cushioning and protection to prevent the blade from directly contacting other components during operation. Simultaneously, the installation height of the silicone pad 9, the suction tube 5, and the blown film tube 4 is consistent with the height of the conveying assembly, helping to maintain the stability of the material during transport and ensuring a smooth and wrinkle-free transition of the film material during conveying, adsorption, and blowing.

[0029] In addition, the heated sealing and cutting knife 7 is also equipped with a pressure plate 6 and a brush 8. The pressure plate 6 is in direct contact with the upper surface of the suction tube 5 and is used to firmly press the protective film 1 during the heated sealing and cutting operation. The brush bristles of the brush 8 are lower than the bottom surface of the pressure plate 6, which plays a role in removing chips and guiding the movement of the film material, while flattening the cut film tail end to ensure the packaging film coating effect. The blade length of the heated sealing and cutting knife 7 is greater than the width of the protective film 1 to ensure that the film material is completely covered and a neat cut is achieved during the cutting process.

[0030] The working principle of this utility model: The protective film 1 is brought to the suction pipe 5 via the guide roller group 2 and the conveying assembly. The suction pipe 5 is controlled by a solenoid valve and starts working to hold the film. The blowing pipe 4 is also controlled by a solenoid valve and does not generate a blowing airflow at this time. When the rock wool felt 13 is conveyed on the production line, and the front of the rock wool felt 13 passes the inlet photoelectric detector 10, the suction pipe 5 stops suctioning the film, and the blowing pipe 4 generates an upward blowing airflow, blowing the protective film 1 into the air. A portion of the protective film 1 automatically attaches to the front of the rock wool felt 13. After the action is completed, the blowing stops, and the protective film 1 moves forward with the rock wool felt 13. When the tail of the rock wool felt 13 leaves the outlet photoelectric detector 11, the film is cut and suction begins at the same time. The heated sealing and cutting knife 7 falls and contacts the silicone pad 9, cutting the protective film 1. The pressure plate 6 falls and contacts the suction pipe 5, and the suction pipe 5 generates negative pressure at the same time, firmly adsorbing and fixing the protective film 1. After the protective film 1 is cut, since the conveying assembly is constantly running, the protective film 1 following the rock wool felt 13 is prone to springing back and rolling due to the tension. At this time, the brush 8 can press down the protective film 1 to keep it in an unfolded state. The rock wool felt 13 enters the felt rolling machine with the film for rolling. The telescopic cylinder 12 pulls the pressure plate 6, the heating and sealing cutter 7 and the brush 8 back to their original positions at the same time, and the film covering action is completed.

[0031] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
