Description

Technical Field

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

[0002] Composite films are polymer materials made by bonding two or more different materials through physical or chemical methods, and are mainly used in the packaging field. Their substrates include plastic films (such as polyethylene PE, polyester PET), metal foils (such as aluminum foil AL), paper, etc., and are formed through technologies such as extrusion lamination, adhesive lamination, or co-extrusion.

[0003] When laminating films using adhesives, brushes are commonly used to clean the film surface. However, static electricity can attract dust particles from the air, causing them to adhere to the film. Even if the brush removes some dust, the static electricity prevents some dust from remaining on the film's outer surface, compromising the lamination process. Furthermore, adhesives are highly susceptible to changes in ambient temperature and humidity, requiring separate control of these factors during lamination, which increases costs.

[0004] In view of this, we propose a thin film composite device. Utility Model Content

[0005] The purpose of this invention is to provide a thin film lamination device that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A film laminating device includes a housing, on one side of which a plurality of feed rollers are rotatably mounted. A laminating cavity is formed at the end of the housing away from the feed rollers. A washing mechanism and a drying mechanism are provided inside the housing. The washing mechanism is used to wash the film, and the drying mechanism is used to dry the film.

[0008] Preferably, the washing mechanism includes a working chamber, which is located inside the housing near the feed roller. Multiple water spray nozzles are fixedly installed at both the upper and lower ends of the working chamber, and the multiple water spray nozzles are arranged in an array.

[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] Please see Figures 1-4 A film laminating device includes a housing 1. Multiple feed rollers 2 are fixedly mounted at one end of the housing 1 for feeding raw materials for film lamination. The feed rollers 2 are active conveying rollers, and the rotation of the feed rollers 2 drives the feeding of raw materials. The housing 1 is equipped with a washing mechanism 3 and a drying mechanism 4. The washing mechanism 3 is used to rinse the surface of the raw film with water and to recover the rinsed water. The drying mechanism 4 uses hot air blowing and multiple sponges for absorption, to dry the rinsed film surface.

[0028] A glue roller 5 is rotatably mounted inside the housing 1 for applying glue to the cleaned and dried film, facilitating the subsequent lamination process. A lamination chamber 6 is located at the end of the housing 1 furthest from the feed roller 2. The lamination chamber 6 is connected to both the washing mechanism 3 and the drying mechanism 4. The temperature and humidity within the lamination chamber 6 can be adjusted via the washing mechanism 3 and the drying mechanism 4, thereby improving lamination efficiency and the final lamination effect. A lamination roller 7 is rotatably mounted inside the lamination chamber 6 for laminating the film.

[0029] The water washing mechanism 3 includes a working chamber 33, which is located inside the housing 1 near the feed roller 2. Multiple water spray nozzles 36 are fixedly installed at the upper and lower ends of the working chamber 33 near the feed roller 2. The water spray nozzles 36 are connected to the water tank 31 via a water pump 32, and the water pump 32 can transport the water in the water tank 31 to the water spray nozzles 36 for spraying.

[0030] Multiple water spray nozzles 36 are arranged in an array, and the water spray direction of the water spray nozzles 36 is set at an angle. The direction of the water spray nozzles 36 is opposite to the direction of movement of the film, so that impurities on the surface of the film can be removed more efficiently.

[0031] The bottom of the working chamber 33 is provided with an inclined surface 34, which allows water sprayed from the water nozzle 36 to flow down the inclined surface 34 under the action of gravity. A recovery tank 35 is provided on the side of the housing 1 at the bottom of the inclined surface 34, and the recovery tank 35 is connected to the water tank 31. Water is transported from the water tank 31 to the water nozzle 36 through the water pump 32. The water nozzle 36 cleans the surface of the membrane and the cleaned water flows through the inclined surface 34 into the recovery tank 35 and finally flows back into the water tank 31 to form a cycle.

[0032] Multiple air blowing nozzles 43 are fixedly installed at the upper and lower ends of the working chamber 33 away from the feed roller 2. The air blowing nozzles 43 are connected to a fan 41 through a heating chamber 42. The fan 41 and the heating chamber 42 can blow air at a fixed temperature onto the film surface through the air blowing nozzles 43. The multiple air blowing nozzles 43 are arranged in an array, and the nozzle direction of the air blowing nozzles 43 is set at an angle opposite to the direction of film movement, so that the hot air can blow off the water on the film surface and dry the film surface.

[0033] Multiple cleaning rollers 44 are also rotatably installed inside the housing 1. The surface of the cleaning rollers 44 is preferably made of sponge material, which can absorb the moisture remaining on the film surface and also isolate the working chamber 33 and the composite chamber 6 to prevent excessive moisture from affecting the subsequent film lamination.

[0034] An atomizing pipe 37 is fixedly installed between the water pump 32 and the composite chamber 6. A heating branch pipe 45 is fixedly installed between the heating chamber 42 and the composite chamber 6. The atomizing pipe 37 and the heating branch pipe 45 are fixedly connected, and a flow valve 38 is fixedly installed on the atomizing pipe 37. The water flow rate in the atomizing pipe 37 can be adjusted by the flow valve 38, and the water flow is atomized into fine water droplets by the atomizing pipe 37. Then, by mixing with the hot air in the heating branch pipe 45, the temperature and humidity in the composite chamber 6 can be controlled.

[0035] A thin film composite device, the working principle of which is as follows:

[0036] The film to be laminated enters the working chamber 33 through the feed roller 2. The film first passes through multiple water spray nozzles 36, where the water flow from the nozzles washes away dust and other impurities from both the top and bottom surfaces. The film then passes through multiple air blowers 43 and a cleaning roller 44. The air blowers 43 apply hot air to the film surface, blowing away water and drying the surface. Simultaneously, the film is further cleaned and dehydrated as it passes through the cleaning roller 44, which also acts as a barrier between the working chamber 33 and the laminating chamber 6. After cleaning, the film is coated with adhesive by the glue roller 5 and finally laminated by the laminating roller 7.

[0037] After use, the water can flow down the inclined plane 34 under the action of gravity, flow into the recycling tank 35 through the inclined plane 34, and finally flow back into the water tank 31 to form a cycle, thus avoiding waste of water resources.

[0038] When performing film lamination in the lamination chamber 6, the water flow rate in the atomizing tube 37 can be adjusted by the flow valve 38, and the water flow is atomized into fine water droplets by the atomizing tube 37. Then, by mixing with the hot air in the heating branch pipe 45, the temperature and humidity in the lamination chamber 6 can be controlled, thereby providing a suitable temperature and humidity range for film lamination and improving the effect of film lamination.
