TECHNICAL FIELD

[0001] The utility model relates to the field of film production, especially to a film production compression assembly. BACKGROUND

[0002] Film production is a process of making a thin and uniform sheet material from raw materials through a specific process. These films are widely used in packaging, electronic products, medical, construction and other fields, and have the characteristics of lightness, transparency, moisture resistance, barrier and so on. Film compression is an important method for ensuring the uniform thickness and smooth surface of the film during the film production process. It is usually used in the production process of plastic film, metal film, coated film, etc.

[0026] 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.

[0027] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a film production pressing assembly, comprising: a bottom support plate 1 for bottom support; support frame plates 2 fixedly connected to both sides of the top of the bottom support plate 1; traction blocks 19 slidably connected to both sides of the inner side of the support frame plates 2; extrusion transfer rollers 5 rotatably connected inside the traction blocks 19; a first pulley 6 fixedly connected to the front side of the extrusion transfer rollers 5; a mounting frame 3 fixedly connected to the left side of the front end of the front support frame plate 2; the mounting frame 3 is connected to the first pulley 6 via a double-rotation drive mechanism to achieve relative reverse rotation of the two extrusion transfer rollers 5; electric push rods 17 fixedly connected to the right side of the inner side of the support frame plate 2; the output end of the electric push rod 17 is connected to the inner side of the traction blocks 19 via an adjustment frame to achieve adjustment of the spacing between the first pulleys 6; the adjustment frame includes a pulling plate 16 located at the output end of the electric push rod 17. The upper and lower sides of the plate 16 are rotatably connected to traction rods 18. The two sides of the pulling plate 16 are respectively slidably connected to the inside of the support frame plate 2. The outer sides of the traction rods 18 are respectively rotatably connected to the inner side of the traction block 19. The double-rotation drive mechanism includes rotating rods 21 located inside the mounting frame 3 and rotating on both sides. The outer side of the mounting frame 3 is fixedly connected to a drive motor 4. The drive end of the drive motor 4 is fixedly connected to the front end of the upper rotating rod 21. Gears 20 are fixedly connected to the outer sides of the rotating rod 21. The two gears 20 are meshed with each other. The inner side of the outer side of the gears 20 is fixedly connected to a second pulley 22. Multiple pulling rollers 7 are rotatably connected to the outer side of the front support frame plate 2. The second pulley 22 and the pulling rollers 7 at the same angle are connected to the first pulley 6 by a belt. Anti-detachment plates 23 are fixedly connected to the outer rear side of the extrusion transmission roller 5 to restrict the movement of the extrusion transmission roller 5.

[0028] During the film pressing operation, the electric push rod 17 is activated, causing the pulling plate 16 to be pulled smoothly to the right. During this process, the pulling plate 16 is pulled and slid outward under the action of force, thereby generating an inward pulling force on the traction block 19. This action drives multiple traction blocks 19 to move inward in coordination, effectively reducing the gap between the extrusion transfer rollers 5. When the extrusion transfer rollers 5 on both sides are in close contact with the film material and apply appropriate pressure, the action of the electric push rod 17 is stopped immediately. Then, the drive motor 4 is started, driving the rotating rod 21 on one side to rotate. Through the precise meshing of the gear 20, the second belt pulleys 22 on both sides are driven to rotate synchronously. At the same time, the outer belt causes the pulling roller 7 and the first belt pulley 6 to rotate together. During the movement of the first belt pulley 6, the pulling roller 7 applies a pulling force to the belt to ensure efficient transfer of kinetic energy, thereby achieving precise extrusion and transfer of the film material. The wide applicability of this device is improved, and it can perform efficient extrusion processing on film materials of different thicknesses.

[0029] Reference Figure 1 , Figure 2 and Figure 3The support L-plate 8 is used to support the left side of the support frame plate 2. The upper and lower ends of the inner side of the support L-plate 8 are fixedly connected to the transmission air duct 11. The inner side of the transmission air duct 11 is fixedly connected to multiple air outlet frames 13. The outer air inlet ducts of the transmission air ducts 11 on both sides penetrate the outer wall of the support frame plate 2. The outer side of the support frame plate 2 is equipped with a downward air inlet mechanism to achieve film cooling. The downward air inlet mechanism includes a support sleeve 9 located in the middle of the outer side of the support frame plate 2. The two sides of the support sleeve 9 are fixedly connected to the transmission air frame 10. The inner side of the support sleeve 9 is fixedly connected to the downward air fan 14. The inner side of the support L-plate 8 is rotatably connected to multiple support rollers 12 to achieve film placement and cooling. The inner middle of the transmission air duct 11 is fixedly connected to a dividing plate 15 to achieve the blocking of the opposing air force on both sides.

[0030] The film material to be compressed is threaded between 11 and placed on top of 12. Then, the film material is placed on top of the lower extrusion transfer roller 5. During the extrusion of the film material, 14 on both sides is activated simultaneously to quickly guide the external airflow into the interior of 9. Using a downward blowing technology, the air is quickly squeezed to both sides and flows into the interior of 10. It is then introduced into the interior of 11 through the air inlet of 11. Subsequently, 13 is used to discharge the airflow to the outside. At the same time, 12 on both sides provides stable support for the film. The airflow acts directly on the middle gap of the film and contacts its outer surface to achieve rapid cooling of the film. This process not only promotes the rapid cooling of the film but also helps its outer shape, thereby significantly improving the final compression effect of the device.

[0031] Working principle: The film material to be compressed is passed through the air duct 11 and placed at the top of the support roller 12. The film material is then placed at the top of the lower extrusion conveyor roller 5. At this time, the electric push rod 17 is activated, pulling the pulling plate 16 to the right. The pulling plate 16 is pulled outward by the force, and the outer side of the pulling plate 16 exerts an inward pulling force on the traction block 19, thereby moving multiple traction blocks 19 inward simultaneously, reducing the distance between the extrusion conveyor rollers 5. When the extrusion conveyor rollers 5 on both sides contact and press the film material, the electric push rod 17 is stopped. At this time, the drive motor 4 is activated to rotate one side of the rotating rod 21. Through the meshing of the gears 20, the second belt pulleys 22 on both sides are rotated, and the film material is pushed outward by the external force. The side belt rotates the pulling roller 7 and the first belt pulley 6 simultaneously. When the first belt pulley 6 moves, the pulling roller 7 pulls the belt to ensure the transmission of kinetic energy, thereby extruding and transferring the film material. During the extrusion of the film material, the downward pressure fans 14 on both sides are started at the same time to quickly pull the external airflow into the support sleeve 9. The downward pressure blower quickly squeezes the air into the interior of the transmission air frame 10 on both sides, and enters the interior of the transmission air duct 11 through the air inlet duct of the transmission air duct 11. The airflow is discharged to the outside through the air outlet frame 13. The support rollers 12 on both sides support the film. The airflow synchronously contacts the outer surface of the film directly through the gap in the middle, thereby cooling the film and making it cool down quickly.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
