Description

Technical Field

[0001] The utility model relates to the technical field of transfer printing, in particular to a UV film printing device. Background Art

[0002] Film printing involves printing various patterns on the surface of flexible films to enhance their aesthetics. It is widely used in various film-printed products, such as the film printing machine disclosed in Chinese utility model patent No. CN202210038489.6 and the wide-format thermal transfer laminating device disclosed in Chinese utility model patent No. CN202122953243.5. However, existing film printing equipment cannot achieve rapid transfer. The main reason is that the glue transferred to the flexible film does not dry quickly, resulting in low production efficiency. Furthermore, the equipment cannot perform continuous processing. After film printing is completed, the machine must be shut down to replace the flexible film, further affecting production efficiency. Furthermore, if problems arise with the equipment, it cannot be quickly dismantled for maintenance. Therefore, further improvements are necessary. Utility Model Content

The first film laminating glue roller group F and the second film laminating glue roller group G are respectively located in front and back positions of the film laminating glue roller group H, and slide back and forth in the direction of the film laminating roller group H respectively.

[0067] In this embodiment, the first laminating rubber roller group F, the second laminating rubber roller group G, and the laminating roller group H are respectively disassembled and assembled on the first laminating rubber roller quick-release opening 29, the second laminating rubber roller quick-release opening 30, and the laminating roller quick-release opening 31 in an up-down pointing manner, so as to facilitate the quick disassembly and assembly of the first laminating rubber roller group F, the second laminating rubber roller group G, and the laminating roller group H. In addition, since the first laminating rubber roller group F and the second laminating rubber roller group G can be respectively positioned forward and backward relative to the laminating roller group H, the gap between the first laminating rubber roller group F, the second laminating rubber roller group G, and the laminating roller group H can be adjusted, thereby adjusting the capacity of the glue entering between the first laminating rubber roller group F, the second laminating rubber roller group G, and the laminating roller group H, as well as the pressing force on the soft film, so as to meet the transfer production requirements of different soft films.

[0068] The first film pressing rubber roller group F and the second film pressing rubber roller group G both include left and right frames 32. The left and right frames 32 are quickly detached from the first film pressing rubber roller quick-release opening 29 and the second film pressing rubber roller quick-release opening 30 respectively.

[0070] When working, the lamination roller driver 42 drives the lamination roller 40 to rotate through the engagement of the lamination roller gear 44 and the lamination roller drive gear 43. When working, the bearing seat driving cylinder 36 slides on the left and right frames 32 through the lamination rubber roller bearing seat 33 through the cooperation of the bearing seat slider 38 and the frame slide rail 37. It can not only adjust the gap between the first lamination rubber roller 34, the second lamination rubber roller 35 and the lamination roller 40, but also adjust the lateral sliding position of the soft film during the transfer process to prevent the soft film from deviation during the transfer process.

[0071] At least two cooling guide roller groups I are also provided on the main frame 1, and the at least two cooling guide roller groups I respectively include a first cooling roller 45 and a second cooling roller 46. The first cooling roller 45 and the second cooling roller 46 are arranged with a front-to-back interval and are located between the rear ultraviolet lamp group D and the film collecting device B. Cooling roller bearing seats 47 are rotatably provided at both ends of the first cooling roller 45 and the second cooling roller 46. Cooling roller quick-release openings 48 are provided at the top of the main frame 1 corresponding to the at least two cooling guide roller groups I. The cooling roller bearing seats 47 are quickly released on the cooling roller quick-release openings 48. A cooling roller driver 49 is also provided on the main frame 1. The first cooling roller 45 and the second cooling roller 46 are respectively driven and connected to the cooling roller driver 49.

[0072] The cooling roller driver 49 can directly drive the first cooling roller 45 and the second cooling roller 46 to rotate when in operation.

[0073] The first laminating rubber roller 34 , the second laminating rubber roller 35 , the laminating roller 40 , the first cooling roller 45 , and the second cooling roller 46 are hollow inside and are respectively connected to a cooling rotary joint 50 , which is connected to a cold liquid supply end.

[0074] In this embodiment, the cooling liquid passes through the first lamination rubber roller 34, the second lamination rubber roller 35, the lamination roller 40, the first cooling roller 45, and the second cooling roller 46 respectively through the cooling rotary joint 50, so that the soft film wrapped around the above-mentioned rollers can be cooled after absorbing the energy of ultraviolet rays and heating, so as to avoid damage to the soft film during the transfer process. At the same time, it can also effectively reduce the cooling time of the soft film due to the high temperature after transfer, so that the soft film can be wound up after transfer, thereby improving the winding effect.

[0075] In this embodiment, the center line between the first cooling roller 45 and the second cooling roller 46 is parallel to the horizontal line, and the height at which they are set is lower than the height at which the third turning guide roller 73 is set, and higher than the height at which the first unfolding roller 76, the second unfolding roller 77, the first film pressing rubber roller 34, the film pressing roller 40, and the second film pressing rubber roller 35 are set. The center line between the first unfolding roller 76, the second unfolding roller 77, the first film pressing rubber roller 34, the film pressing roller 40, and the second film pressing rubber roller 35 is parallel to the horizontal line, and the height at which they are set is higher than the height at which the first turning guide roller 71 and the fifth turning guide roller 75 are set.

[0077] like Figure 4 As shown, the soft film on the second film-laying air-expansion shaft 21 is sequentially wound around the second film-discharging guide roller 25, the first unwinding roller 76, the first turning guide roller 71, the second turning guide roller 72, the first film-pressing rubber roller 34, the film-pressing roller 40, the second film-pressing rubber roller 35, the third turning guide roller 73, the first cooling roller 45, the second cooling roller 46, the fourth turning guide roller 74, the fifth turning guide roller 75, the second unwinding roller 77, the second film-collecting guide roller 27, and finally wound up by the second film-collecting air-expansion shaft 23.

[0078] The main frame 1 is further provided with a transverse connecting rod 51 , and a scraper block 52 is movably connected to the transverse connecting rod 51 . The scraper block 52 scrapes off the glue between the laminating roller 40 and the first laminating rubber roller 34 or the second laminating rubber roller 35 when it moves.

[0079] In this embodiment, the scraper block 52 is set between the lamination roller 40 and the first lamination roller 34. The user can directly drive the scraper block 52 to move horizontally on the horizontal connecting rod 51 to scrape off the glue between the lamination roller 40 and the first lamination roller 34.

[0080] The film pressing ultraviolet lamp group C includes left and right lamp frames 53, a first lampshade 54 and a second lampshade 55. A lamp frame connecting beam 56 is fixed between the left and right lamp frames 53. The ends of the first lampshade 54 and the second lampshade 55 are respectively fixed between the left and right lamp frames 53. The first lampshade 54 and the second lampshade 55 are tilted and located below the film pressing roller 40. The first ultraviolet lamp and the second ultraviolet lamp are respectively arranged inside the first lampshade 54 and the second lampshade 55. The first upper light-transmitting groove 57 and the second upper light-transmitting groove 58 are respectively arranged on the top of the first lampshade 54 and the second lampshade 55. The first upper light-transmitting groove 57 and the second upper light-transmitting groove 58 are respectively tilted toward the film pressing roller 40.

[0081] In this embodiment, the front and rear sides of the first lampshade 54 and the second lampshade 55 are respectively provided with film pressing side shading plates 80, and the outer sides of the left and right lamp frames 53 are respectively provided with film pressing bottom shading plates 81. Thereby, the ultraviolet light generated by the first ultraviolet lamp and the second ultraviolet lamp can be effectively blocked at the sides and bottom ends, so that the first ultraviolet lamp and the second ultraviolet lamp only focus on the film pressing roller 40, which not only avoids the leakage of ultraviolet rays, but also ensures that the soft film on the film pressing roller 40 can effectively absorb ultraviolet energy during transfer.

[0082] The main frame 1 is provided with a lamp stand driving cylinder 59 and a lamp stand slide rail 60 pointing up and down, and the left and right lamp stands 53 are respectively provided with lamp stand sliders 61. The telescopic end of the lamp stand driving cylinder 59 points up and down and is connected to the driving of the left and right lamp stands 53. The lamp stand slider 61 and the lamp stand slide rail 60 slide with each other.

[0083] When working, the lamp holder driving cylinder 59 drives the left and right lamp holders 53 to slide through the lamp holder slider 61 and the lamp holder slide rail 60 to adjust the upper and lower positions between the first ultraviolet lamp, the second ultraviolet lamp and the film pressing roller 40, thereby adjusting the ultraviolet energy of the first ultraviolet lamp and the second ultraviolet lamp irradiated to the soft film on the film pressing roller 40 to meet the processing requirements of different soft films.

[0084] The glue supply assembly E includes a glue supply bracket 62, which is located above the first film-pressing rubber roller 34 and the second film-pressing rubber roller 35.

The glue supply bracket drive bracket 65 is fixedly provided with a glue supply bracket drive cylinder 66. The telescopic end of the glue supply bracket drive cylinder 66 points forward and backward and is driven and connected to the glue supply bracket 62. The glue supply bracket slider 63 and the glue supply bracket slide rail 70 slide in cooperation with each other.

[0085] In this embodiment, the glue supply bracket 62 is located above the first film-pressing rubber roller 34. The glue supply bracket driving cylinder 66 drives the glue supply bracket 62 to move back and forth during operation, thereby driving the glue supply tube 64 to move back and forth synchronously, so that the glue on the glue supply tube 64 can fall to any position above the first film-pressing rubber roller 34, ensuring the stability of the glue supply.

[0086] A side opening 67 is provided on the main frame 1 , and a glue receiving tray 68 is quickly detached through the side opening 67 . The glue receiving tray 68 is located between the film glue pressing device and the second ultraviolet lamp group D.

[0087] In this embodiment, the glue receiving plate 68 is quickly disassembled laterally through the side opening 67 below the first laminating rubber roller 34, the second laminating rubber roller 35, and the laminating roller 40. This not only facilitates the disassembly and assembly of the glue receiving plate 68, but also allows the glue that falls off the first laminating rubber roller 34, the second laminating rubber roller 35, and the laminating roller 40 to be recycled, thereby avoiding waste of resources and ensuring environmental hygiene.
