The printed matter is transported by the transport roller 12, and the film unwinding roller 11 unwinds the film, and the printed matter is hot pressed between the upper hot pressing roller 21 and the lower hot pressing roller 22.

[0037] Reference Figure 2 and Figure 3 A cleaning assembly 3 is arranged on the frame 1. The cleaning assembly 3 includes a cleaning box 31 and a cleaning brush 32. The cleaning box 31 is arranged on the frame 1 and distributed along the width direction of the frame 1. The cleaning box 31 is provided with openings 311 at opposite sides. The openings 311 are distributed along the length direction of the cleaning box 31. The cleaning brush 32 is arranged at the opening 311 of the cleaning box 31. Two cleaning brushes 32 are arranged and are relatively arranged at the upper and lower sides of the opening 311. When the printed matter is transported through the cleaning box 31, the cleaning brushes 32 on the upper and lower sides brush off some impurities on the printed matter. A brush roller 312 is arranged in the cleaning box 31. Two brush rollers 312 are arranged and are distributed in parallel up and down. A motor 13 is arranged on the frame 1. The motor 13 drives the brush roller 312 to rotate. A blowing assembly 4 is arranged in the cleaning box 31. A hair suction mechanism 5 is arranged on one side of the frame 1. The hair suction mechanism 5 is connected to the cleaning box 31. The brush roller 312 in the cleaning box 31 will adhere to impurities such as lint on the printed matter. After the hot pressing is completed, the blowing component 4 will blow off the impurities on the brush roller 312, and the hair suction mechanism 5 will suck away the impurities, reducing the amount of impurities in the cleaning box 31, and having a better cleaning effect on the impurities on the printed matter.

[0038] Reference Figure 4 The hair suction mechanism 5 includes a processing box 51 and a fan 52. The processing box 51 is arranged on one side of the frame 1. The processing box 51 is connected to the cleaning box 31 through an air duct. The fan 52 is arranged in the processing box 51. An air outlet 511 is arranged on one side of the processing box 51. A filter 512 is arranged in the processing box 51. The fan 52 sucks impurities in the cleaning box 31 to the processing box 51 and filters them through the filter 512.

[0039] Reference Figure 5 and Figure 6, a cleaning box 31 is rotatably installed with a connecting plate 313 at an opening 311. The connecting plates 313 are distributed along the length direction of the opening 311. One end of a cleaning brush 32 is inserted at the downward side of the connecting plate 313. A locking member 7 is arranged on the connecting plate 313. The locking member 7 includes a plug rod 71 and a first spring 72. The plug rod 71 is slidably installed on the connecting plate 313. The first spring 72 is sleeved on the plug rod 71. A slot 321 is formed on the cleaning brush 32. When the cleaning brush 32 is inserted at the connecting plate 313, the first spring 72 pushes the plug rod 71 to be inserted into the slot 321 of the cleaning brush 32, and the installation of the cleaning brush 32 is completed. When it is necessary to remove the cleaning brush 32, one end of the plug rod 71 is pulled to be separated from the cleaning brush 32, and the cleaning brush 32 can be taken off.

[0040] Refer to Figure 5 , a second spring 314 is arranged in the cleaning box 31. One end of the second spring 314 is connected to one side of the connecting plate 313. The second spring 314 pushes the connecting plate 313 and further pushes the cleaning brush 32 to clean. The elastic tightening reduces the tightening force of the cleaning brush 32 on the printed matter and reduces the probability of damaging the surface of the printed matter.

[0041] Refer to Figure 3 , a blowing assembly 4 includes a blowing pipe 41 and a blowing nozzle 42. The blowing pipe 41 is arranged in the cleaning box 31 and is arranged parallel to the brush roller 312. There are two groups of blowing pipes 41 which are relatively arranged on the opposite sides of the brush roller 312. The blowing pipe 41 is rotatably connected to the cleaning box 31. One end of the blowing pipe 41 is connected to an external air pump. The blowing nozzle 42 is arranged on the blowing pipe 41 and is communicated with the blowing pipe 41. There are several blowing nozzles 42 which are arranged along the length direction of the blowing pipe 41. After the blowing pipe 41 intakes air, it blows out through the blowing nozzle 42 to clean the brush roller 312 and blow off the attached impurities on the brush roller 312.

[0042] Refer to Figure 2 , a rotating member 6 is arranged on the frame 1. The rotating member 6 includes a driving cylinder 61, a rack 62 and a gear 63. The driving cylinder 61 is arranged on one side surface of the frame 1. The gear 63 is rotatably installed on the frame 1. The gear 63 is coaxially connected to one end of the blowing pipe 41. The rack 62 is slidably installed on the frame 1. One end of the rack 62 is connected to one end of the piston rod of the driving cylinder 61. The two sides of the rack 62 are respectively meshed with one side of the upper and lower gears 63. The driving cylinder 61 drives the rack 62 to slide. The rack 62 drives the gear 63 to rotate and further drives the blowing pipe 41 to rotate. When the blowing pipe 41 rotates, the impurities attached to each part in the cleaning box 31 are blown up and sucked away by the hair suction mechanism 5. At the same time, the upper and lower blowing pipes 41 are driven to rotate, and the driving operation is convenient.

[0043] Refer to Figure 3, a scraper 14 is arranged on the frame 1 along the width direction of the frame 1. One side edge of the scraper 14 is attached to the circumferential side wall of the upper hot pressing roller 21. A third spring 15 is arranged on the frame 1. One end of the third spring 15 is connected to one side surface of the scraper 14. The third spring 15 pushes one side of the scraper 14 to tightly press against the side wall of the upper hot pressing roller 21, scraping off some film residues attached to the upper hot pressing roller 21, and reducing the problem of the decline in the laminating quality caused by laminating the residues onto the printed matter. A collection box 16 is arranged on the frame 1 below the scraper 14, and the residues scraped off by the scraper 14 fall to the collection box 16 for collection.

[0044] The implementation principle of a printing laminating machine according to an embodiment of the present application is as follows: The printed matter is transported by the transport roller 12, the film unwinding roller 11 unwinds the film, and hot pressing lamination is performed between the upper hot pressing roller 21 and the lower hot pressing roller 22 with the printed matter. When the printed matter is transported through the cleaning box 31, the cleaning brush 32 brushes off some impurities on the printed matter, and the brush roller 312 in the cleaning box 31 adheres to impurities such as fluff, and there are fewer impurities on the printed matter.

[0045] The air blowing pipe 41 blows up the impurities on the brush roller 312 and in the cleaning box 31, and the fan 52 sucks the impurities to the treatment box 51 on one side for collection, reducing the probability of impurities remaining in the cleaning box 31 and being taken out with the printed matter.

[0046] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
