[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The following is combined with Figures 1-5 This invention describes a continuous grid printing apparatus.

[0028] In one embodiment, a continuous grid printing apparatus includes: a printing machine body 100, which is composed of a support 101, a material transfer structure 102 and a printing structure 103;

[0029] The cleaning mechanism 200 is located above the support 101 and is used to clean the paper scraps on the surface of the paper conveyed by the material conveying structure 102.

[0030] The cleaning mechanism 200 includes a fixed frame 201, which is fixedly installed on the top of the bracket 101. A liftable lifting frame 203 is provided below the fixed frame 201. A first cleaning roller 204 and a second cleaning roller 205 are provided below the lifting frame 203 and above the paper. The outer arc surfaces of the first cleaning roller 204 and the second cleaning roller 205 are provided with cleaning brushes. A dust suction port 212 is opened on the outer arc surface of the first cleaning roller 204 between the cleaning brushes. The first cleaning roller 204 is connected to the dust suction component. The cleaning brushes on the outside of the first cleaning roller 204 and the second cleaning roller 205 are made of nylon.

[0031] A first cleaning roller 204 and a second cleaning roller 205 are provided above the paper conveyed by the material conveying structure 102 and on the top of the support 101. Both are installed below the lifting frame 203. The lifting frame 203 can be raised and lowered by extending and retracting the working end of the upper hydraulic telescopic rod 202, thereby adjusting the distance between the first cleaning roller 204 and the second cleaning roller 205 according to the paper thickness, ensuring the efficiency of the first cleaning roller 204 and the second cleaning roller 205 in cleaning paper scraps from the paper surface.

[0032] Cleaning brushes are provided on the outer arc surfaces of the first cleaning roller 204 and the second cleaning roller 205. The cleaning brushes are made of nylon. When the first cleaning roller 204 and the second cleaning roller 205 are driven to rotate above the paper, the nylon cleaning brushes are elastic, not easily deformed, and have a smooth surface, making it difficult to snag paper fibers. At the same time, the anti-static properties of the nylon brushes are selected to reduce the secondary adsorption of paper scraps on the surface of the cleaning brushes, thus reducing secondary pollution to the paper.

[0033] The first cleaning roller 204 has a cavity 213 inside. One end of the first cleaning roller 204 passes through the side plate 208 and is keyed to the output shaft of the rotary motor 209 provided on the outer side wall of the side plate 208. The side plates 208 are respectively provided at both ends of the bottom surface of the lifting frame 203. The other end of the first cleaning roller 204 is provided with a dust suction pipe 214. The dust suction pipe 214 is interconnected with the cavity 213. The other end of the dust suction pipe 214 passes through the side wall of another side plate 208 and is connected to the dust suction assembly.

[0034] When the first cleaning roller 204 and the second cleaning roller 205 are driven to rotate by the corresponding rotary motor 209 provided on the outer side wall of the side plate 208, the cleaning brush on the outer arc surface of the second cleaning roller 205 brushes and cleans the paper scraps on the surface below. During the process of the paper being conveyed by the material conveying structure 102, the dust suction port 212 opened on the outer arc surface of the first cleaning roller 204 is sucked up by the dust suction component, and the paper scraps are sucked up through the dust suction pipe 214 rotatably provided inside the other end of the first cleaning roller 204 and enter the interior of the threaded hose 211. After passing through the threaded hose 211, they enter the interior of the vacuum cleaner 210. The worker can clean the dust collection box inside the vacuum cleaner 210 periodically.

[0035] like Figure 4 and Figure 5 As shown, the vacuuming assembly includes a vacuum cleaner 210 and a threaded hose 211. The vacuum cleaner 210 is disposed on the top of the mounting bracket 201, and the vacuum cleaner 210 is connected to the end of the vacuum pipe 214 that passes through the side plate 208 via the threaded hose 211.

[0036] In this embodiment, the vacuum cleaner 210 is connected to the end of the suction pipe 214 that passes through the side plate 208 via a threaded hose 211. The other end of the suction pipe 214 is connected to the cavity 213 inside the first cleaning roller 204. When the vacuum cleaner 210 is started, the threaded hose 211 and the suction pipe 214 suck up the shredded paper that enters the cavity 213 through the suction port 212 and suck it into the dust collection box inside the vacuum cleaner 210 for collection, so that workers can clean the shredded paper inside the dust collection box regularly.

[0037] like Figure 4 As shown, a second cleaning roller 205 is provided between the two sets of side plates 208, located outside the first cleaning roller 204. The rotation of the second cleaning roller 205 is arranged between the two sets of side plates 208. One end of the second cleaning roller 205 passes through the side wall of the side plate 208 and is keyed to the output shaft of the corresponding rotary motor 209.

[0038] In this embodiment, a second cleaning roller 205 is rotatably disposed between the two sets of side plates 208 on the side outside the first cleaning roller 204 and away from the printing structure 103. The second cleaning roller 205 is driven to rotate by a rotary motor 209 corresponding to the second cleaning roller 205, so that the cleaning brush on the outer arc surface of the second cleaning roller 205 brushes and cleans the paper scraps on the paper surface, so that the dust collection component can pick them up through the dust collection port 212 on the outer arc surface of the first cleaning roller 204.

[0039] like Figure 2 and Figure 3 As shown, side plates 208 are respectively provided at both ends of the bottom surface of the lifting frame 203. A hydraulic telescopic rod 202 is provided on the top surface of the fixed frame 201. The working end of the hydraulic telescopic rod 202 passes through the top surface of the fixed frame 201 and is fixedly connected to the surface of the lifting frame 203. Slider 206 is provided on both side walls of the lifting frame 203. The slider 206 is slidably disposed inside the groove 207 opened on the inner walls of both sides below the fixed frame 201.

[0040] In this embodiment, the lifting frame 203 is raised and lowered by the extension and retraction of the working end of the hydraulic telescopic rod 202, thereby driving the first cleaning roller 204 and the second cleaning roller 205 at the bottom of the lifting frame 203 to rise and fall. This allows the spacing between the first cleaning roller 204 and the second cleaning roller 205 and the paper to be adjusted according to the thickness of the paper, further increasing the applicability of this utility model.

[0041] like Figure 2 As shown, a collection box 215 is provided inside the support 101 below the paper conveying structure 102. The collection box 215 has a pull-out collection box inside, and the inner wall of the collection box is covered with adhesive paper.

[0042] In this embodiment, a collection box 215 is provided inside the support 101 below the paper conveying structure 102, and a pull-out collection box is provided inside the collection box 215. The inner wall of the collection box is covered with adhesive paper to collect and adhere the paper scraps cleaned by the first cleaning roller 204 and the second cleaning roller 205, so as to avoid the paper scraps floating in the air and causing secondary pollution to the cleaned paper.

[0043] Additional notes:

[0044] The printing press body 100 in this application may be of the model AFPS-1020LD;

[0045] It includes, but is not limited to, the following structures:

[0046] The frame in this application includes the support 101, the unwinding unit, the traction and drive components, the printing unit in this application includes the printing structure 103, the drying components, the rewinding unit, etc.

[0047] The material transfer structure 102 in this application includes the unwinding unit and the winding unit described above.

[0048] The cleaning mechanism 200 in this application is installed above the support 101 and is located at the unwinding unit. It is used to clean impurities such as paper scraps and hair from the surface of the paper to be printed.

[0049] Working principle: Before use, the lifting frame 203 is raised and lowered by controlling the movement of the hydraulic telescopic rod 202, and the distance between the first cleaning roller 204, the second cleaning roller 205 and the paper is adjusted.

[0050] After adjustment, the feeding structure 102 and printing structure 103 are started. The feeding structure 102 conveys the paper into the printing structure 103. During the paper conveying process, the paper passes under the first cleaning roller 204 and the second cleaning roller 205. The second cleaning roller 205 brushes the paper scraps on the surface of the paper. The first cleaning roller 204 sucks up the paper scraps cleaned from the surface of the paper through the dust suction component. The paper scraps enter the cavity 213 through the dust suction port 212. The vacuum cleaner 210 draws the paper scraps into the dust collection box inside the vacuum cleaner 210 through the dust suction pipe 214 and the threaded hose 211. The worker only needs to clean the dust collection box inside the vacuum cleaner 210 periodically.

[0051] Inside the support 101, below the paper conveying structure 102, there is a collection box 215. The inner wall of the collection box inside the collection box 215 is covered with adhesive paper. The adhesive paper is used to adhere the paper scraps cleaned by the first cleaning roller 204 and the second cleaning roller 205, so as to avoid the paper scraps causing secondary pollution to the cleaned paper.
