Description

Technical Field

[0001] This utility model relates to the field of thin film processing technology, specifically a thin film extrusion molding device. Background Technology

[0002] Since aluminum foil is generally 10-20 micrometers thick, its strength is limited and its puncture resistance is poor. To improve the puncture resistance of aluminum foil, a plastic film needs to be laminated onto the surface of the aluminum foil to form a composite aluminum foil. In the process of processing composite aluminum foil, extrusion equipment is required. One side of the plastic film is coated with an adhesive. Through the extrusion device and the action of the adhesive, the plastic film and aluminum foil can be extruded to form a composite aluminum foil. In the existing extrusion molding equipment, the positions of the two rollers used to extrude the aluminum foil and plastic film do not change, which makes it difficult for the aluminum film and plastic film to pass between the two rollers and is difficult to meet the application requirements. Utility Model Content

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-4As shown, a film extrusion molding apparatus includes a support frame 6, a top plate 7 above the support frame 6, and a guide rod 8 connecting the top plate 7 and the support frame 6. It also includes a movable plate 9 located between the support frame 6 and the top plate 7 and slidably connected to the guide rod 8. A spring 10 is sleeved on the guide rod 8, located between the top plate 7 and the movable plate 9. Rollers 11 are provided on the upper surface of the support frame 6 and the lower surface of the movable plate 9. A rubber sleeve 12 is fitted onto the outer surface of the rollers 11. A device for driving the rollers located on the support frame 6 is also provided. The motor 13 rotates the roller 11 on the top. One end of each of the two rollers 11 is provided with a meshing gear 14. An adjustment plate 15 is provided between the top plate 7 and the movable plate 9. A screw 16 is rotatably connected to the top plate 7. A handwheel 17 is provided at the upper end of the screw 16. The screw 16 is threadedly connected to the adjustment plate 15. A fixed rod 18 that is slidably connected to the top plate 7 is provided on the upper surface of the adjustment plate 15. It also includes several sets of connecting rod assemblies 19. One end of the connecting rod assembly 19 is fixedly connected to the adjustment plate 15, and the other end of the connecting rod assembly 19 is fixedly connected to the movable plate 9.

[0018] When the aluminum foil and plastic film are first passed between the two rollers 11, the screw 16 is first rotated by the handwheel 17. When the screw 16 rotates, it can move the adjusting plate 15 vertically upward through the threaded connection between the screw 16 and the adjusting plate 15, and the sliding connection between the fixing rod 18 on the adjusting plate 15 and the top plate 7. During the upward movement of the adjusting plate 15, it will first drive the connecting rod assembly 19 to move. The connecting rod assembly 19 will gradually change from a bent state to a straight state. When the connecting rod assembly 19 changes to a straight state, the adjusting plate 15 can drive the movable plate 9 to move upward through the connecting rod assembly 19. The rollers 11 mounted on the movable plate 9 will also move upward. As the movable plate 9 moves upward, the spring 10 on the guide rod 8 is further compressed. When the distance between the rubber sleeves 12 on the upper and lower rollers 11 is increased, the aluminum foil and plastic film pass through the two rubber sleeves 12. Then, by rotating the handwheel 17, the two rollers rotate in opposite directions. When the movable plate 9 and the rollers 11 on the movable plate 9 are reset, and the connecting rod assembly 19 is in a bent state, the handwheel 17 is stopped. At this time, the spring 10 can push the movable plate 9 and the rollers 11 on the movable plate 9 to move downward, so that the rubber sleeves 12 on the two rollers 11 are kept in a squeezed state, thereby realizing the extrusion and bonding of aluminum foil and plastic film.

[0019] The plastic film is coated with an adhesive during the production process, so there is no need to reapply adhesive to the plastic film during the extrusion and lamination of aluminum foil and plastic film.

[0020] The cross-section of the regulating plate 15 is H-shaped to improve its stability.

[0021] Furthermore, the movable plate 9 is provided with a through groove 20 for avoiding the screw 16, so as to prevent the upper surface of the movable plate 9 from abutting against the lower end of the screw 16 during the upward movement of the movable plate 9.

[0022] Furthermore, it also includes a steering assembly, which includes a mounting frame 21. Two sets of guide units are mounted on the mounting frame 21. Each guide unit includes a steering roller 22 and a guide roller 23. The two guide rollers 23 of the two sets of guide units are located between the two steering rollers 22. It also includes two sets of unwinding units 4 and one set of winding units 5. Both the two sets of unwinding units 4 and the one set of winding units 5 are located on the same side of the support frame 6. The unwinding units 4 and the winding units 5 are existing technologies. The placement and unwinding states of the aluminum foil roll 1 and the plastic film roll 2, and the winding state of the composite aluminum foil roll 3 are as follows: Figure 4 As shown, by using the steering roller 22 and guide roller 23, the overall structure of the film extrusion molding device can be made more compact, reducing the floor space required.

[0023] After the composite aluminum foil roll 3 is extruded, the edges of the composite aluminum foil roll 3 can be trimmed using a trimming device.

[0024] Furthermore, it also includes a processing chamber 24, which is equipped with a sealed door 25 and a ventilation filter 26. The processing chamber 24 can be accessed and exited through the sealed door 25. The ventilation filter 26 is used to extract the air inside the processing chamber 24, while the outside air enters the interior of the processing chamber 24 after passing through the ventilation filter 26. The processing chamber 24 is installed in a cleanroom. The processing chamber 24 can further improve the air cleanliness during the extrusion of aluminum foil and plastic film. Before the film extrusion molding device starts working, the staff needs to leave the processing chamber 24. It can also isolate a certain amount of noise when entering the cleanroom and improve safety.

[0025] The air drawn out of the processing chamber 24 by the ventilation filter 26 will not enter the cleanroom, but will be discharged to the outside of the cleanroom through the ventilation duct system. The outside air cannot flow back into the processing chamber 24 through the ventilation duct system.

[0026] Furthermore, the processing chamber 24 is assembled from a metal frame and sheet metal. The sheet metal is made of colorless and transparent material, the metal frame is made of aluminum alloy, and the sheet metal can be made of glass or plastic.
