The printing machine 1 is arranged on the conveyor belt 11, and a carrying platform 12 for stacking cardboard is arranged in front of the conveyor belt 11.

[0031] The feeding mechanism 2 is composed of a driving part, a suction part and a cleaning part 29. The suction part is connected to the bottom of the driving part and is located above the cardboard on the supporting platform 12. Through the driving of the driving part, the suction part can absorb the cardboard stacked on the supporting platform 12 and feed it to the conveyor belt 11; the cleaning part 29 is connected to the rear side of the suction part, moves with the movement of the suction part, and is used to clean the cardboard on the conveyor belt 11.

[0032] The driving part includes: a moving frame 21, which is arranged in front of the printing machine 1, and long guide rods 22 are arranged on the left and right ends of the moving frame 21, and the two ends of the moving frame 21 are respectively slidably sleeved on the two long guide rods 22, and the front and rear sides of the two long guide rods 22 are respectively fixedly connected to the carrier platform 12 and the printing machine 1, and a first power source for driving the moving frame 21 to move forward and backward is arranged between the two long guide rods 22, and a parallel lifting plate 26 is arranged directly below the moving frame 21, and telescopic rods 25 are arranged on the left and right ends above the lifting plate 26, and the telescopic ends and fixed ends of the two telescopic rods 25 are respectively fixedly connected to the lifting plate 26 and the moving frame 21, and a second power source for driving the lifting plate 26 to rise and fall is arranged between the two telescopic rods 25.

[0033] It should be noted that the first power source is an electric cylinder 23, which is fixedly installed on the front side of the printing machine 1, and the piston rod of the electric cylinder 23 is fixedly connected to the rear side of the moving frame 21; the second power source is an electric cylinder 24, which is fixedly installed on the bottom of the moving frame 21, and the piston rod of the electric cylinder 24 is fixedly connected to the top of the lifting plate 26.

[0034] In this embodiment, when the electric cylinder 24 is started to push the lifting plate 26 down, the lifting plate 26 can stably push the suction part below it to automatically drop to above the surface of the cardboard stacked on the supporting platform 12 under the telescopic guiding action of the two telescopic rods 25 thereon. Then, the electric cylinder 1 23 is started to push the moving frame 21. At this time, the moving frame 21 can stably drive the cardboard adsorbed by the suction part below the lifting plate 26 to be automatically loaded onto the conveyor belt 11 under the guiding action of the two long guide rods 22, thereby realizing automatic loading, which can effectively save manpower and time costs.

[0035] The material suction part includes: three evenly distributed mounting frames 27 and a plurality of suction cups 28. The tops of the three mounting frames 27 are fixedly connected to the bottom of the lifting plate 26, and the three mounting frames 27 and the lifting plate 26 are arranged in a vertical state. A plurality of suction cups 28 are evenly distributed and fixedly connected to the bottoms of the three mounting frames 27. A plurality of suction cups 28 are arranged above the supporting platform 12, and a plurality of suction cups 28 are fixedly connected to suction hoses. The other ends of the plurality of suction hoses are fixedly connected to suction fans, and the suction fans are fixedly installed on the lifting plate 26.

[0036] In this embodiment, when the lifting plate 26 drives a plurality of suction cups 28 to descend above the surface of the cardboard stacked on the supporting platform 12, the suction fan is started to generate negative pressure, and the negative pressure is transmitted to the surface of each suction cup 28 through each suction hose. Then, under the action of the negative pressure, the cardboard can be fixedly adsorbed on the surface of the plurality of suction cups 28 for loading. The loading method of the suction cups 28 adsorption can effectively avoid the problem of possible damage to the cardboard caused by the use of clamps or clamps. At the same time, the suction cups 28 can also avoid scratches or deformation, so as to ensure the quality and efficiency of printing.

[0037] The cleaning part 29 includes: a connecting frame 291, which is fixedly installed on the rear side of the three mounting frames 27, and two left-right symmetrical limit seats 294 are fixedly installed on the rear side of the connecting frame 291. A scraper 295 is arranged below the two limit seats 294, and a cleaning pad 296 is fixedly installed at the bottom of the scraper 295 by bolts. The cleaning pad 296 is made of rubber or polyurethane material, and a number of evenly distributed elliptical holes are opened at the bottom of the cleaning pad 296, and a number of soft brushes are fixedly installed in each elliptical hole. Short guide rods 293 are fixedly installed on both ends above the scraper 295, and the upper ends of the two short guide rods 293 pass through the two limit seats 294 respectively, and are respectively slidably connected to the two limit seats 294, and the upper ends of the two short guide rods 293 are fixedly installed with limit blocks, and a third power source for driving the scraper 295 to rise and fall is arranged between the two short guide rods 293.

[0038] It should also be noted that the third power source is the electric cylinder 292 , which is fixedly installed in the middle of the rear side of the connecting frame 291 , and the piston rod of the electric cylinder 292 is fixedly connected to the top of the scraper 295 .

[0039] In this embodiment, after the cardboard is adsorbed and loaded onto the conveyor belt 11 by the suction cup 28, the adsorption between the suction cup 28 and the cardboard is released, and at the same time, the electric cylinder 292 is started to push the scraper 295 down, and the scraper 295 can stably lower the cleaning pad 296 installed below it to the surface of the loaded cardboard under the sliding guidance of the two short guide rods 293. Then, under the driving action of the driving unit, the cleaning pad 296 below the scraper 295 moves on the cardboard surface as the mounting frame 27 moves forward. Since the cleaning pad 296 is made of rubber or polyurethane material, when the cleaning pad 296 moves on the cardboard surface When the cleaning pad 296 is in motion, the dust and dirt on the surface of the cardboard can be scraped off and adsorbed on the cleaning pad 296 by utilizing the soft elasticity of the rubber or polyurethane. Meanwhile, a plurality of elliptical holes are provided at the bottom of the cleaning pad 296, and a soft brush is installed in each elliptical hole. Therefore, by providing the elliptical holes and the soft brush, the contact area between the cleaning pad 296 and the surface of the cardboard can be further increased, thereby further improving the adsorption effect of the cleaning pad 296 made of rubber or polyurethane material, playing the role of dust prevention and decontamination, thereby preventing the presence of dust, stains or other impurities on the surface of the cardboard, thereby affecting the printing effect and reducing the quality of printing.

[0040] When in use, first start the electric cylinder 24 to push the lifting plate 26 down. At this time, the lifting plate 26 can stably push the plurality of suction cups 28 below it to automatically descend to above the surface of the cardboard stacked on the carrying platform 12 under the telescopic guidance of the two telescopic rods 25 on it.

[0041] Next, the suction fan is started to generate negative pressure, and the negative pressure is transmitted to the surface of each suction cup 28 through each suction hose. At this time, under the action of the negative pressure, the cardboard can be fixedly adsorbed on the surface of several suction cups 28, and then the electric cylinder 1 23 is started to push the moving frame 21. At this time, the moving frame 21 can stably drive the cardboards adsorbed by several suction cups 28 to be automatically loaded onto the conveyor belt 11 under the guidance of the two long guide rods 22;

[0042] After that, the adsorption between the suction cup 28 and the cardboard is released, and the electric cylinder 3 292 is started to push the scraper 295 down. At this time, the scraper 295 can stably push the cleaning pad 296 down to the surface of the loaded cardboard under the sliding guidance of the two short guide rods 293. At the same time, under the pushing action of the electric cylinder 1 23, the moving frame 21 will drive the mounting frame 27 to automatically move and reset to the top of the supporting platform 12. However, when the mounting frame 27 moves forward, the cleaning pad 296 will move on the cardboard surface with the movement of the mounting frame 27. Since the cleaning pad 296 is made of rubber or polyurethane material, when the cleaning pad 296 moves on the cardboard surface, it is convenient to use. With the soft elasticity of rubber or polyurethane, dust and dirt on the surface of the cardboard can be scraped off and adsorbed on the cleaning pad 296. At the same time, since a number of elliptical holes are opened at the bottom of the cleaning pad 296, and a soft brush is installed in each elliptical hole, when the cleaning pad 296 adsorbs dust on the surface of the cardboard, the contact area between the cleaning pad 296 and the surface of the cardboard can be further increased by providing the elliptical holes and the soft brush, thereby further improving the adsorption effect of the cleaning pad 296 made of rubber or polyurethane material, playing the role of dust prevention and decontamination, and thus avoiding the presence of dust, stains or other impurities on the surface of the cardboard, which affects the printing effect and reduces the quality of printing;

[0043] Finally, the cleaned cardboards can be sequentially conveyed to the bottom of the printing machine 1 for printing operation under the conveying action of the conveyor belt 11.
