Description

Technical Field

[0001] The utility model belongs to the technical field of film coating, and in particular relates to a large-area evaporation film coating device. Background Art

[0002] When using an evaporative coating device for coating, generally speaking, the thicker the base film to be coated, the closer the evaporation mechanism of the evaporative coating device can be to the base film on the main roller, thereby better avoiding the loss of evaporation material and the coating layer coated on the base film will be thicker.

[0003] Prior art discloses an evaporation coating device with patent publication number CN220952011U. The device comprises an evaporation mechanism, a moving mechanism, and a rolling element. The moving mechanism includes a drive unit and a moving unit. The drive unit drives the moving unit to reciprocate toward or away from the evaporation mechanism. The rolling element is fixed to the moving unit and is used to wrap around at least a base film and, driven by the moving unit, move the base film toward or away from the evaporation mechanism. While this device addresses the issue of malfunctioning the evaporation coating device when adjusting the distance between the evaporation mechanism and the base film, it still suffers from the following deficiencies in actual use: Practically speaking, the device cannot ensure that dust adhering to the base film surface is removed during the transport process before coating. This results in inconsistent coating quality during the coating process, reducing the coating quality.

[0004] Therefore, a large-area evaporation coating device is needed to solve the problem in the prior art that the surface of the base film used for coating cannot be cleaned of dust. Utility Model Content

[0027] In use, when the base film is conveyed in close contact with the bottom of the dust removal roller 701, the electrostatic dust removal effect of the dust removal roller 701 can adsorb the static electricity and dust on the surface of the base film at this time, and under the arrangement of the cleaning brush 702, the dust adsorbed on the dust removal roller 701 is swept off, and under the operation of the fan 706, the airflow flows into the dust removal box 704 and the installation box 705 through the through hole 703, thereby the swept dust can be sucked, the dust is flown into the installation box 705 and is collected through the dustproof net 708, and under the arrangement of the flow guide plate 7011, the dust can be prevented from flowing back, thereby the dust removal effect is improved, and the film plating effect on the base film is improved.

[0028] Further as Figure 5As shown, worth noting is that the limiting assembly 7010 comprises a positioning plate 7010a fixedly installed on the top of the fixed frame 707, the positioning plate 7010a is fixedly connected with a fixed block 7010c on the top of the installation box 705, the fixed block 7010c is fixedly connected with a limiting rod 7010d, the fixed block 7010c is movably installed with a positioning block 7010e through the limiting rod 7010d, the positioning block 7010e is provided with a limiting groove 7010f matched with the limiting rod 7010d, the outer surface of the positioning block 7010e is fixedly connected with a movable block 7010g, and the positioning plate 7010a is provided with a positioning opening 7010b corresponding to the positioning block 7010e and the movable block 7010g.

[0029] In use, when the dust screen 708 is installed, the movable block 7010g is turned over to rotate on the limiting rod 7010d through the limiting groove 7010f, when the movable block 7010g is turned over to match the positioning opening 7010b, the movable block 7010g is pushed to slide on the limiting rod 7010d through the limiting groove 7010f, and then the movable block 7010g is clamped in the positioning opening 7010b, so that the fixed frame 707 is installed and fixed, and vice versa, which facilitates disassembly and improves practicability.

[0030] According to the above working process, the dust removal mechanism 7 can effectively clean the dust on the surface of the base film before the evaporation device 2 and the coating main roller 4 are used for coating the base film, so as to avoid the influence of the adhered dust on the coating quality of the subsequent coating work, thereby improving the production efficiency.

[0031] Further as shown in Figure 2 and Figure 4 As shown, worth noting is that the adjusting mechanism 8 comprises two electric telescopic rods 801 fixedly installed on the top of the mounting frame 6 and arranged on the front and rear sides of the dust removal box 704, the electric telescopic rod 801 is fixedly connected with a sliding seat 802 at the bottom end, the sliding seat 802 is movably arranged in the mounting frame 6 corresponding to the matching arrangement of the movable opening 803, and the sliding seat 802 is rotatably connected with the dust removal roller 701 through a bearing.

[0032] In use, under the operation of the electric telescopic rod 801, the sliding seat 802 can be pushed to match the position of the base film conveying and adjust the matching of the coating main roller 4, improve the conveying stability and ensure the dust removal quality.

[0033] This solution has the following working process: when this device is used, the base film material that needs to be coated is passed through the bottom of the dust removal roller 701 and the bottom of the coating main roller 4. The evaporation device 2 is operated in conjunction with the slide rail 3 and the baffle 5 to coat the base film. At this time, during the base film transportation process, when the base film is conveyed in contact with the bottom of the dust removal roller 701, the static electricity and dust removal effect of the dust removal roller 701 can adsorb the static electricity and dust on the surface of the base film, and under the setting of the cleaning brush 702, the dust adsorbed on the dust removal roller 701 is swept down. At the same time, under the operation of the fan 706, the air flow passes through the through-hole 703 to circulate into the dust removal box 704 and the installation box 705, and then the swept dust can be absorbed, so that the dust flies into the installation box 705 and is collected by the dustproof net 708. At the same time, the guide plate 7011 is set When the dust-proof net 708 is installed, the movable block 7010g is flipped over so that it can rotate on the limit rod 7010d through the limit groove 7010f. When the movable block 7010g is flipped over to match the positioning port 7010b, the movable block 7010g is pushed so that it can slide on the limit rod 7010d through the limit groove 7010f. Then, the movable block 7010g is snapped into the positioning port 7010b through the movable block 7010g, thereby fixing the fixed frame 707. Otherwise, it is easy to disassemble it, thereby improving its practicality.

[0034] In summary: through the provision of the dust removal mechanism 7, before the base film is coated by the evaporation device 2 and the coating main roller 4, the dust on the surface of the base film can be effectively cleaned to avoid the adhered dust affecting the coating quality of the subsequent coating work, thereby improving its production efficiency; through the provision of the adjustment mechanism 8, in conjunction with the work of the dust removal mechanism 7 and the coating main roller 4, the dust removal mechanism 7 can be adjusted to match the position of the transported base film, thereby ensuring the dust removal effect on the base film and further improving the practicality of the device.
