[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Specific implementation examples are given below.
[0024] Please see Figures 1-4This utility model provides a fireproof door panel pressing device, including a pressing device body 1; a pair of piston cylinders 11 are fixedly connected to the side wall of the pressing device body 1; the piston cylinders 11 are symmetrically arranged on both sides of the pressing device body 1 and have the same structure; a piston rod 12 is slidably connected to the inner side wall of the piston cylinder 11; the piston rod 12 is fixedly connected to the pressing device body 1; an exhaust pipe 13 is fixedly connected to the side wall of the piston cylinder 11; the exhaust pipe 13 penetrates the wall of the pressing device body 1 and is fixedly connected to it; a pair of guide plates 14 are fixedly connected to the side wall of the exhaust pipe 13; the guide plates 14 are symmetrically arranged on both sides of the exhaust pipe 13 and have the same structure; a connecting pipe 15 is fixedly connected to the side wall of the guide plate 14; the connecting pipe 15 penetrates the wall of the guide plate 14 and is fixedly connected to it; in use, the pressure is released through the side wall of the pressing device body 1. When the wall-mounted pressing mechanism descends, it simultaneously compresses the piston rod 12. As the piston rod 12 moves, it squeezes out the gas in the piston cylinder 11. At this time, the gas is discharged to the outside through the exhaust pipe 13, thereby blowing air onto the door panel surface stacked above the pressing device body 1. Simultaneously, when the gas passes through the guide plate 14, it can disperse the airflow, and some of the airflow will enter the connecting pipe 15. Through the connecting pipe 15, it blows air onto the door panel surface from both sides, thereby increasing the contact area between the airflow and the door panel. During this process, blowing air through the exhaust pipe 13 can clean the dust and impurities attached to the door panel surface, reducing the adhesion of dust and impurities, and thus improving the pressing effect of the door panel. At the same time, the guide plate 14 and the connecting pipe 15 can increase the dispersion of the airflow and increase the contact area with the door panel, thereby improving the cleaning effect.
[0025] Furthermore, such as Figures 1-4As shown, a pair of guide rails 2 are fixedly connected to the side wall of the pressing device body 1; the guide rails 2 are symmetrically arranged on both sides of the pressing device body 1 and have the same structure; a bidirectional screw 21 is rotatably connected to the inner side wall of the guide rail 2; the bidirectional screw 21 passes through the wall of the guide rail 2 and is rotatably connected to it; a pair of sliders 22 are threadedly connected to the side wall of the bidirectional screw 21; the sliders 22 are symmetrically arranged on both sides of the bidirectional screw 21 and have the same structure; the bidirectional screw 21 passes through the wall of the slider 22 and is threadedly connected to it; a limit block 23 is fixedly connected to the side wall of the slider 22; in use, first hold the bidirectional screw 21 and rotate it, and as the bidirectional screw 21 rotates, the sliders 22 can move. The sliders 22 slide within the guide rail 2 as they move closer or further apart, adjusting the spacing between the limiting blocks 23. Once the adjustment is complete, as the pressing mechanism on the side wall of the pressing device body 1 descends, the limiting blocks 23 first contact the door panel above the pressing device body 1. Using the inclined surface of the limiting blocks 23, the door panel is pushed towards the center, making it stacked neatly. During this process, the limiting blocks 23 can limit the pressing of the door panel, improving the neatness of the door panel above the pressing device body 1. At the same time, the movement of the sliders 22 can adapt to door panels of different sizes, thereby improving the flexibility of the limiting blocks 23 in use.
[0026] Furthermore, such as Figures 1-4 As shown, a pair of fixed frames 3 are fixedly connected to the side wall of the pressing device body 1; the fixed frames 3 are symmetrically arranged on both sides of the pressing device body 1 and have the same structure; a pair of spring rods 31 are symmetrically fixedly connected to the side wall of the fixed frame 3; the ends of the spring rods 31 are fixedly connected to the same cleaning brush plate 32; a connecting rod 33 is fixedly connected to the side wall of the cleaning brush plate 32; in use, when the pressing mechanism on the wall of the pressing device body 1 descends to perform the pressing operation, it can simultaneously drive the fixed frames 3 to descend, and finally bring the cleaning brush plate 32 into contact with the surface of the pressing device body 1, so as to clean the surface of the pressing device body 1, sweep away the dust and impurities attached to the surface of the pressing device body 1, and the cleaning brush plate 32 can also clean the surface of the pressing device body 1 during cleaning. The elasticity of the spring rod 31 can push the cleaning brush plate 32, allowing it to make full contact with the surface of the pressing device body 1. During cleaning, the multiple bristles on the side wall of the cleaning brush plate 32 can be fixedly connected by the connecting rod 33, so that they are concentrated together during cleaning. In this process, the cleaning brush plate 32 moves on the surface of the pressing device body 1, which can clean the dust and impurities attached to the surface of the pressing device body 1, reduce the adhesion of dust and impurities, and thus reduce the corrosion of the pressing device body 1 caused by long-term dust and impurities, thereby improving the service life of the pressing device body 1. At the same time, the connecting rod 33 can increase the concentration of the bristles during cleaning, improving the cleaning effect.
[0027] Furthermore, such as Figures 1-4As shown, a pair of elastic sheets 4 are symmetrically fixed to the side wall of the cleaning brush plate 32; a plurality of protrusions 41 are uniformly fixed to the side wall of the pressing device body 1; during use, as the cleaning brush plate 32 moves downward, the elastic sheets 4 can come into contact with the protrusions 41. As the cleaning brush plate 32 moves, the protrusions 41 can squeeze the elastic sheets 4 to produce a certain deformation. When the two are misaligned, the elasticity of the elastic sheet 4 will cause it to swing and produce a certain vibration effect, thereby shaking off the dust and impurities attached to the surface of the cleaning brush plate 32. In this process, the vibration generated by the swing of the elastic sheet 4 can clean the dust and impurities attached to the surface of the cleaning brush plate 32, reduce the adhesion of dust and impurities, and thus increase the subsequent cleaning effect of the cleaning brush plate 32.
[0028] Furthermore, such as Figures 1-4 As shown, a heat-absorbing plate 5 is fixedly attached to the side wall of the cleaning brush 32; a plurality of heat dissipation fins 51 are uniformly fixedly attached to the side wall of the heat-absorbing plate 5; during use, when the cleaning brush 32 descends to clean the surface of the pressing device body 1, the heat-absorbing plate 5 can adhere to the wall of the pressing device body 1. The heat-absorbing plate 5 can absorb some of the heat inside the pressing device body 1, and then conduct it to the wall of the heat dissipation fins 51 through the heat-absorbing plate 5. The heat dissipation fins 51 release the heat to the outside. In this process, the heat-absorbing plate 5 can absorb some of the heat on the wall of the pressing device body 1 to achieve a heat dissipation effect, improve the cooling speed of the pressing device body 1 during operation, and thus increase the pressing effect of the pressing device body 1.
[0029] Furthermore, such as Figures 1-4 As shown, a copper tube 6 is fixedly connected to the side wall of the heat sink 51; the copper tube 6 penetrates the wall of the heat sink 51 and is fixedly connected to it; in use, the copper tube 6 can disperse the heat on the wall of the heat sink 51, making it evenly distributed on the walls of multiple heat sinks 51, allowing the heat to be released quickly. In this process, the copper tube 6 can play a role in the even distribution of heat on the wall of the heat sink 51, improve the heat release speed, and thus increase the heat conduction and release effect of the heat absorption plate 5.
[0030] Working principle: During use, as the pressing mechanism on the side wall of the pressing device body 1 descends, it simultaneously squeezes the piston rod 12. As the piston rod 12 moves, it squeezes out the gas in the piston cylinder 11. At this time, the gas is discharged to the outside through the exhaust pipe 13, thus blowing air onto the door panel surface stacked above the pressing device body 1. Simultaneously, when the gas passes through the guide plate 14, the airflow is dispersed, and some of the airflow enters the connecting pipe 15. Through the connecting pipe 15, air is blown onto the door panel surface from both sides, thereby increasing the contact area between the airflow and the door panel. During use, first hold the bidirectional screw 21 and rotate it. As the bidirectional screw 21 rotates, it can... The sliders 22 are moved closer or further apart, sliding within the guide rail 2 to adjust the spacing between the limiting blocks 23. After adjustment, as the pressing mechanism on the side wall of the pressing device body 1 descends, the limiting blocks 23 first contact the door panel above the pressing device body 1. Using the inclined surface of the limiting blocks 23, the door panel is pushed towards the center, making it neatly stacked. During use, when the pressing mechanism on the wall of the pressing device body 1 descends for pressing operations, the fixing frame 3 also descends, finally bringing the cleaning brush 32 into contact with the surface of the pressing device body 1, thus cleaning the surface of the pressing device body 1. The cleaning process removes dust and impurities adhering to the surface of the pressing device body 1. During cleaning, the cleaning brush 32 is pushed by the elasticity of the spring rod 31, ensuring full contact with the surface of the pressing device body 1. The connecting rod 33 secures multiple bristles on the side wall of the cleaning brush 32, concentrating them together during cleaning. During use, as the cleaning brush 32 descends, the elastic plate 4 contacts the protrusion 41. As the cleaning brush 32 moves, the protrusion 41 compresses the elastic plate 4, causing a certain deformation. When the two are misaligned, the elastic plate 4... The elasticity of the elastic sheet 4 will cause it to swing and produce a certain vibration effect, which can shake off the dust and impurities attached to the surface of the cleaning brush plate 32. When the cleaning brush plate 32 descends to clean the surface of the pressing device body 1, the heat absorption plate 5 can be brought into contact with the wall of the pressing device body 1. The heat absorption plate 5 can absorb some of the heat inside the pressing device body 1, and then conduct it to the wall of the heat sink 51 through the heat absorption plate 5. The heat sink 51 releases the heat to the outside. When in use, the copper tube 6 can disperse the heat on the wall of the heat sink 51, so that it is evenly distributed on the walls of multiple heat sinks 51, allowing the heat to be released quickly.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
