Among them, along the length direction of the first adsorption roller assembly 211, the plurality of first conveying wheels 2112 are evenly disposed on the first adsorption roller core 2111.

[0057] In this embodiment, when the material contacts the first conveying wheels 2112 on the first adsorption roller core 2111, the friction force during the rotation of the plurality of first conveying wheels 2112 is used to drive the material to feed.

[0062] In this embodiment, when the material is conveyed from the first conveying mechanism 21 to the second conveying mechanism 22, through the air suction of the first air suction mechanism 23, the second adsorption holes of the second adsorption roller core adsorb the upper surface of the material to improve the flatness of the material surface. Moreover, the second conveying wheels are in contact with the upper surface of the material, and through the frictional force when the second conveying wheels rotate, the conveying of the material is realized. Among them, the number of the second conveying wheels is not limited and can be one, two, three, etc. The first air duct 232 is respectively communicated with the first adsorption roller core 2111 and the second adsorption roller core through two air suction sub-pipes.

[0063] In one embodiment, as Figure 1 and Figure 3 shown, the material anti-extrusion conveying device further includes a conveying device 3 located at the discharge end of the feeding device 2. The conveying device 3 is located below the printing device.

The third conveying mechanism 31 is located at the discharge end of the feeding device 2. The second air suction mechanism 32 is connected to the third conveying mechanism 31. Through the air suction of the second air suction mechanism 32, the third conveying mechanism 31 can adsorb the lower surface of the material and output the material.

[0064] When printing is required on the surface of the material, the material can be conveyed through the conveying device 3. In this embodiment, the material is conveyed from the discharge end of the feeding device 2 to the third conveying mechanism 31. Through the suction of the second air suction mechanism 32, the third conveying mechanism 31 can adsorb the lower surface of the material to improve the surface flatness of the material. At the same time, the printing device located above the conveying device 3 can print the upper surface of the material, and the conveying of the material is realized through the conveying device 3.

[0065] Among them, the structure of the third conveying mechanism 31 is similar to that of the second conveying mechanism 22. The third conveying mechanism 31 is located below the second conveying mechanism 22, and the vertical distance between the third conveying mechanism 31 and the second conveying mechanism 22 is greater than or equal to the height of the material, so as to facilitate the second conveying mechanism 22 and the third conveying mechanism 31 to adsorb the upper surface and the lower surface of the material respectively, so as to realize the adsorption and conveying of the material.

The waste vibrating device 4 includes an air box 41, a fourth conveying mechanism 42, a third air suction mechanism 43 and a dust cleaning member 44. The air box 41 is arranged on the frame 1. The fourth conveying mechanism 42 is arranged in the air box 41. The third air suction mechanism 43 is arranged on the air box 41 and is used for sucking air from the air box 41. Through the suction of the third air suction mechanism 43, the fourth conveying mechanism 42 can adsorb the lower surface of the material and output the material. The dust cleaning member 44 is arranged at one end of the waste vibrating device 4 close to the conveying device 3 and is used for cleaning the surface of the material.

[0067] In this embodiment, after the material is output by the conveying device 3, it first passes through the dust cleaning member 44 to clean the surface of the material, so as to remove impurities such as dust and waste on the surface of the material. Then, the fourth conveying mechanism 42 conveys the material. The third air suction mechanism 43 can suck air from the air box 41, so that the fourth conveying mechanism 42 adsorbs the lower surface of the material and conveys the material. Among them, the dust cleaning member 44 can be, for example, a brush, and the brush is arranged at one end of the waste removing device 4 close to the conveying device 3 along the direction perpendicular to the conveying direction of the material. The third air suction mechanism 43 includes a third air suction motor arranged on the frame 1.

[0069] In this embodiment, the material is output from the conveying device 3 to the fourth conveying mechanism 42, and the material is conveyed through the obliquely upward arranged belt 421; and, since belt adsorption holes 4211 are arranged on the belt 421, when the third air suction mechanism 43 sucks air from the air box 41, the belt 421 can adsorb the lower surface of the material, so as to improve the flatness of the material surface while preventing the material from falling off the belt 421. Among them, the number of the fourth conveying mechanisms 42 is not limited, and can be one, two, three, etc. For example, Figure 4 six fourth conveying mechanisms 42 are arranged in [reference], and correspondingly, through the cooperation of six belts 421, the stability of conveying the material is improved.

[0070] In one embodiment, the waste removing device 4 further includes a feeding plate 45. The feeding plate 45 is located at one end of the waste removing device 4 close to the conveying device 3 and below the dust cleaning member 44.

[0071] In this embodiment, the setting of the feeding plate 45 can play a guiding role to facilitate the material to be conveyed to the fourth conveying mechanism 42.

[0072] In one embodiment, the waste removing device 4 further includes a fifth conveying mechanism 46. The fifth conveying mechanism 46 is located below the fourth conveying mechanism 42 and is used for conveying waste.

[0073] In this embodiment, when the material passes through the waste removing device 4, the dust cleaning member 44 can remove waste such as dust and impurities on its surface. When the fallen waste lands on the fifth conveying mechanism 46, it can be conveyed to the waste collection place by the fifth conveying mechanism 46. Among them, the fifth conveying mechanism 46 can be, for example, a conveyor belt, etc.

[0074] An exemplary embodiment of the present application provides the working principle of a material anti-extrusion conveying device. Herein, cardboard is taken as an example to illustrate the materials in this embodiment.

[0075] When the first adsorption roller assembly 211 is in the first position, it can receive the cardboard. After receiving the cardboard, the first adsorption roller assembly 211 is driven by the lifting drive assembly 212 to rise to the second position; the first conveying wheel 2112 is brought into contact with the lower surface of the cardboard, and the rotation drive assembly drives the first adsorption roller core 2111 and the first conveying wheel 2112 to rotate to achieve the conveyance of the cardboard; meanwhile, through the suction of the first air suction mechanism 23, the first adsorption roller assembly 211 can adsorb the lower surface of the cardboard to improve the surface flatness of the cardboard. After the first adsorption roller assembly 211 conveys the cardboard to the second adsorption roller assembly, the lifting drive assembly 212 drives the first adsorption roller assembly 211 to descend to the first position to complete one paper feeding process and wait for the next paper feeding.

[0076] The first adsorption roller assembly 211 conveys the cardboard to the second adsorption roller assembly. Through the suction of the first air suction mechanism 23, the second adsorption roller assembly adsorbs the upper surface of the cardboard to improve the surface flatness of the material; moreover, the second conveying wheel is in contact with the upper surface of the cardboard, and through the rotation of the second conveying wheel, the cardboard is conveyed to the conveying device 3.

[0077] The cardboard is conveyed by the second conveying mechanism 22 to the third conveying mechanism 31. Through the suction of the second air suction mechanism 32, the third conveying mechanism 31 can adsorb the lower surface of the cardboard to improve the surface flatness of the cardboard; meanwhile, the printing device located above the conveying device 3 can print the upper surface of the cardboard.

[0078] After printing, the cardboard is conveyed by the third conveying mechanism 31 to the fourth conveying mechanism 42. The surface of the cardboard is cleaned by the dust cleaning member 44 to remove impurities such as dust and waste on the surface of the material. After cleaning, through the guiding action of the feeding plate 45, the cardboard is conveyed onto the belt 421 that slopes upward. Since the belt 421 is provided with belt adsorption holes 4211, when the third air suction mechanism 43 sucks air from the air box 41, the belt 421 can adsorb the lower surface of the cardboard to improve the surface flatness of the cardboard and prevent the cardboard from falling off the belt 421 at the same time.
