Technical Field

[0001] The utility model relates to the technical field of laminating equipment, in particular to a double-layer release paper laminating device. Background Art

[0002] A laminating device is required in the process of release paper processing, but the existing laminating device still has certain defects.

[0003] A Chinese patent with announcement number CN208881012U discloses a double-layer release paper coating device, which sprays the release paper through an upper nozzle and a lower nozzle to achieve a double-layer coating effect on the release paper, and removes excess film material from the coated release paper through a scraper to allow the film material to be evenly attached to the release paper.

[0004] However, the device still has some shortcomings: in the device, the output pressures of the upper nozzle and the lower nozzle are not equal, and as the film material in the storage box decreases, the output pressure of the upper nozzle gradually decreases, which leads to different film thicknesses on the upper and lower sides of the release paper. In addition, during the film lamination process, the film material that has not contacted the release paper cannot be collected, resulting in waste. Utility Model Content

[0005] The utility model aims to solve the problems existing in the background technology and proposes a double-layer release paper laminating device.

The hot air blowers A and B are respectively located on the upper and lower sides of the release paper to dry the upper and lower sides of the release paper synchronously.

[0012] Preferably, a hollow shaft rotatably connected to the top plate is provided, one end of the U-shaped frame away from the opening is connected to the hollow shaft, the U-shaped frame is connected to the inside of the hollow shaft, and each nozzle is connected to the inside of the U-shaped frame, and the driving mechanism drives the hollow shaft.

The structure plays a guiding role in the subsequent collection of the film material, and the top plate is rotatably connected to the baffle plate, which is convenient for pulling the release paper after the top plate is opened. At the same time, the U-shaped frame is controlled to rotate by the driving mechanism, so that the top plate can rotate automatically when it is flipped and reset, and then the lower nozzle is convenient for being stuck under the release paper. The upper and lower nozzles are uniformly fed by the same liquid pump, so that the laminating output pressure is consistent, thereby keeping the film thickness of the upper and lower sides of the release paper consistent. At the same time, in the process of the liquid pump extracting raw materials in the storage box, the film material that is not in contact with the release paper at the opening of the air collecting hood is sucked into the storage box under the action of negative pressure, which effectively avoids the waste of film material.

[0024] Embodiment 1

[0025] like Figure 1-Figure 4 As shown, a double-layer release paper coating device proposed by the utility model comprises an operating table 1 with a through hole 101, a top plate 7, a driving mechanism 11, an air collecting hopper 13 and a liquid pump 15. A feed roller 2 and a winding roller 3 are arranged on the operating table 1, a baffle 4 is arranged on the operating table 1, and a plurality of guide rollers 5 are arranged between the baffles 4. The top plate 7 is rotatably connected with one side of the baffle 4, a U-shaped frame 9 is arranged on the top plate 7 to rotate with it, and two groups of nozzles 10 are arranged on the U-shaped frame 9 opposite to each other. The driving mechanism 11 drives the U-shaped frame 9 to rotate, so that after the release paper is pulled through the guide roller 5, the lower nozzle 10 of the U-shaped frame 9 is inserted from the edge of the release paper and forms a double-sided coating of the release paper with the upper nozzle 10 during the process of flipping the top plate 7 to reset. A hollow shaft 8 is provided on the top plate 7 and is rotatably connected thereto. One end of the U-shaped frame 9 away from the opening is connected to the hollow shaft 8. The U-shaped frame 9 is connected to the inside of the hollow shaft 8, and each nozzle 10 is connected to the inside of the U-shaped frame 9. The driving mechanism 11 drives and connects the hollow shaft. The gas collecting hopper 13 is connected to the through hole 101 and the storage box 14. The liquid pump 15 is connected to each nozzle 10 and the storage box 14 to deliver the raw materials in the storage box 14 to the nozzle 10. The output end of the liquid pump 15 is connected to the discharge pipe 16, and the other end of the discharge pipe 16 is inserted into the hollow shaft 8 and is rotatably connected thereto. An air guide pipe is provided at the bottom of the gas collecting hopper 13, and the air guide pipe is inserted into the storage box 14 and is located below the liquid level. A filter screen is provided in the gas collecting hopper 13 to prevent dust in the air from entering the storage box 14. A feed port is provided on the storage box 14, and a cover plate rotatably connected thereto is provided on the storage box 14, and the cover plate is sealed with the feed port.

[0026] In this embodiment, when pulling the release paper, the top plate 7 is opened, and then the end of the release paper is directly passed over each guide roller 5 from the feed roller 2 in turn and finally fixed on the winding roller 3, and then the top plate 7 is turned over to reset. During the reset process of the top plate 7, the driving mechanism 11 drives the U-shaped frame 9 to rotate to a state parallel to the plate surface of the baffle 4, and then the lower horizontal end of the U-shaped frame 9 is inserted along the gap between the release paper and the baffle 4, and then the driving mechanism 11 drives the U-shaped frame 9 to rotate and reset. At this time, the upper and lower groups of nozzles 1 0 is located at the upper and lower parts of the release paper respectively, and the liquid pump 15 is started. The liquid pump 15 extracts the film material in the storage box 14 and sends it to the nozzle 10. The upper and lower groups of nozzles 10 perform double-sided coating on the release paper at the same time. Since the air pressure in the storage box 14 needs to be balanced, the excess fine droplet-shaped film material between the baffle 4 and the top plate 7 enters the storage box 14 along the air collecting hopper 13 under the action of negative pressure. Since the air guide pipe at the bottom of the air collecting hopper 13 is inserted below the liquid surface, the droplet-shaped film material quickly merges into the film material. This structure collects the film material that does not contact the release paper during the coating process to avoid waste, and it is also convenient for the traction of the release paper and the subsequent cleaning of the entire structure.

[0027] Embodiment 2

[0028] like Figure 1 and Figure 2 As shown, the utility model proposes a double-layer release paper laminating device. Compared with the first embodiment, a hot air blower A6 is arranged on the side of the operating table 1 close to the winding roller 3, and a hot air blower B12 is arranged on the side of the top plate 7 close to the winding roller 3. The hot air blower A6 and the hot air blower B12 are respectively located on the upper and lower sides of the release paper to synchronously dry the upper and lower sides of the release paper.

[0029] In this embodiment, the hot air blowers A6 and B12 arranged opposite to each other dry the upper and lower surfaces of the release paper simultaneously, thereby improving the bonding and curing efficiency between the film material and the release paper and preventing the film materials from sticking to each other during the rapid winding process of the winding roller 3.

[0030] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
