Description

Technical Field

[0001] The utility model relates to the technical field of flattening devices, in particular to a flattening device for the production of vapor-phase rust-proof films. Background Technique

[0002] The vapor-phase rust-proof film, also known as the VCI vapor-phase rust-proof film, is a new generation of innovative high-tech product based on the combination of polymer materials and VCI vapor-phase rust-proof technology. Its main principle is that after the vapor-phase rust-proof film is packaged and sealed, the VCI contained in the film body begins to sublimate and volatilize rust-proof gas factors, which diffuse and penetrate to the surface of the rust-proof object and adsorb on it, forming a dense protective film layer with a single molecular thickness, isolating the contact between various factors inducing rust and the surface of the rust-proof object, thereby effectively preventing the generation of rust. After its production, it usually needs to be flattened by a flattening device to avoid the existence of air bubbles inside and facilitate transportation.

[0003] At present, when most flattening devices for vapor-phase rust-proof films flatten rust-proof films with different thicknesses, it is usually necessary to rotate the adjusting screw to adjust the distance between the flattening belt and the conveyor belt. Since there are usually four adjusting screws, the adjustment is rather cumbersome, and frequent leveling is required to ensure the flattening effect. Its operation is rather cumbersome, reducing the adjustment efficiency. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The present invention provides a technical solution: As Figures 1-3 shown, in this embodiment, a flattening device for producing a vapor-phase rust preventive film includes a feeding table 1. A first fixing frame 2 is fixedly connected to the top end of the feeding table 1 and near one side. Two mounting frames 3 are fixedly connected to the inner top surface of the first fixing frame 2. A bi-directional lead screw 4 is rotatably connected between the two mounting frames 3. Two driven rods 5 are engaged with the outer surfaces of the two bi-directional lead screws 4. The two ends of the two driven rods 5 are rotatably connected to connecting rods 6. The other ends of the four connecting rods 6 are respectively rotatably connected to two driven frames 7. A mounting plate 9 is fixedly connected to the bottom ends of the two driven frames 7. A flattening belt 10 is rotatably connected to the inside of the mounting plate 9. Among them, by setting the bi-directional lead screw 4, the two driven rods 5 can be driven to move simultaneously. By setting the connecting rods 6, the driven frames 7 can be pushed or pulled to move under the drive of the driven rods 5, so as to realize the adjustment of the position of the flattening belt 10.

[0021] As Figure 2 and Figure 4 shown, a second fixing frame 12 is fixedly connected to the top end of the feeding table 1 and near the other side. A lifting cylinder 13 is fixedly connected to the top end of the second fixing frame 12. The telescopic end of the lifting cylinder 13 penetrates through the top end of the second fixing frame 12 and is fixedly connected to a connecting plate 14. Two rotating frames 15 are rotatably connected to the bottom end of the connecting plate 14. Two driven rollers 16 are rotatably connected to the inside of the two rotating frames 15. By setting the lifting cylinder 13, the connecting plate 14 can be driven to move up and down. By setting the driven rollers 16, they can be unrolled and rolled during the movement of the connecting plate 14. There is a resistance between the driven rollers 16 and the rotating frames 15, which can make the driven rollers 16 have a slight pulling effect on the vapor-phase rust preventive film during the rolling process, realizing the flattening function and preventing wrinkles.

[0022] As Figure 4As shown in the figure, four square through-holes 20 are formed through the top end of the second fixing frame 12. Four limiting rods 18 are slidably connected inside the four square through-holes 20. The bottom ends of the four limiting rods 18 are fixedly connected to the top end of the connecting plate 14, which can position the connecting plate 14, prevent it from skewing, and improve stability.

[0023] As Figure 4 shown in the figure, limiting blocks 19 are fixedly connected to the top ends of the four limiting rods 18. The sizes of the four limiting blocks 19 are larger than the inner sizes of the square through-holes 20. Connecting rods 17 are fixedly connected inside the two rotating frames 15. By setting the limiting blocks 19, the limiting rods 18 can be limited to prevent them from falling off. By setting the connecting rods 17, the structural stability of the rotating frames 15 can be improved.

[0024] As Figure 1 and Figure 3 shown in the figure, two positioning rods 11 are fixedly connected in the middle of the two mounting frames 3. The outer surfaces of the two positioning rods 11 are slidably connected to the inside of the two driven rods 5, which can position the driven rods 5 to prevent them from skewing.

[0025] As Figure 3 shown in the figure, one end of the bidirectional lead screw 4 penetrates through one side wall inside the first fixing frame 2 and is drivingly connected to a positive and negative motor 8. The outer surface of the positive and negative motor 8 is fixedly connected to one side of the first fixing frame 2. The top ends of the two driven frames 7 are respectively slidably connected to the inside of the two mounting frames 3. By setting the positive and negative motor 8, the bidirectional lead screw 4 can be driven to rotate for convenient adjustment. By setting the top ends of the two driven frames 7 to be respectively slidably connected to the inside of the two mounting frames 3, the mounting plate 9 can be positioned to improve stability.

[0026] The present utility model provides a flattening device for producing a vapor-phase rust preventive film. The specific working principle is as follows:

[0027] When it is necessary to flatten vapor-phase rust preventive films with different thicknesses, the staff starts the positive and negative motor 8. The positive and negative motor 8 drives the bidirectional lead screw 4 to rotate, causing the two driven rods 5 to move accordingly. During the movement of the two driven rods 5, the connecting rod 6 is driven to move together. During the movement of the connecting rod 6, the driven frame 7 is pulled or pushed to slide inside the mounting frame 3 to adjust the distance between the flattening belt 10 and the feeding table 1. Before flattening, the lifting cylinder 13 drives the connecting plate 14 to move downward, causing the two driven rollers 16 fixed on the rotating frame 15 to roll on the surface of the vapor-phase rust preventive film, so that the vapor-phase rust preventive film to be flattened can be leveled during the rolling process, facilitating subsequent flattening.

[0028] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
