[0002] When feeding paper in current four-color printers on the market, a roller mechanism is usually used to press the paper and drive it to move into the printer. To ensure the smooth rotation and speed stability of the rollers, lubricating oil is often applied to the rollers. This approach easily causes the lubricating oil to splash onto the paper during the rotation of the rollers, thereby affecting the printing quality.

[0003] After retrieval, the Chinese patent publication number is: CN208410770U. This utility model discloses a dual-rail four-color printing three-dimensional printer, including a printer body, a first printing mechanism and a second printing mechanism arranged in the printer body, a workbench for printing products, a material rack for placing printing consumables, and a controller for controlling the printing process. Before printing, the printing material is placed on the material rack, and the thread end of the printing material is passed through the opening under the material rack and then connected to the corresponding print head. After setting the printing parameters through the touch screen, the upper cover is closed to prepare for printing. During printing, both the first printing mechanism and the second printing mechanism can print on the printing platform.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Refer to Figure 1 、 Figure 4 and Figure 5, an embodiment provided by the present utility model: a four-color printer for preventing oil splashing pollution, including a workbench 1. Hollow boxes 3 are fixedly connected to the front and rear sides inside the workbench 1. A motor one 4 is fixedly connected to the left side of the rear end of the workbench 1. The output end of the motor one 4 penetrates through the workbench 1 and is fixedly connected to a first rotating rod 5. The front end of the first rotating rod 5 sequentially penetrates through the hollow boxes 3 and is fixedly connected to two driving gears 6. The bottom of each of the two hollow boxes 3 is rotatably connected to a second rotating rod 7. Both ends of the two second rotating rods 7 are fixedly connected to rollers 9. Driven gears 8 are fixedly connected to the outer walls of the two second rotating rods 7. The two driven gears 8 are respectively meshed with the corresponding driving gears 6. Oil absorbing plates 10 are slidably connected to the left and right sides inside the two hollow boxes 3. A plurality of limiting holes 11 are opened on the left and right sides of the two hollow boxes 3. Two limiting bolts 12 are rotatably connected to one side of each of the plurality of oil absorbing plates 10. A same hollow horizontal plate 13 is fixedly connected to the front and rear sides inside the workbench 1. Connecting plates 14 are fixedly connected to the front and rear ends on the left side of the hollow horizontal plate 13. The left sides of the two connecting plates 14 are respectively communicated with the right sides of the corresponding hollow boxes 3. A fixing plate 15 is fixedly connected to the right side of the hollow horizontal plate 13. A blower 16 is fixedly connected to the top of the fixing plate 15. One end of the blower 16 is communicated with the right side of the hollow horizontal plate 13. A clamping mechanism 2 is arranged on the top of the workbench 1. A first groove 19 is opened on the top of the hollow horizontal plate 13. A filter plate 20 is slidably connected inside the first groove 19;

[0040] Specifically, first place the paper on the backing plate 208, then turn on the switch 25 to make the motor one 4 rotate. The first rotating rod 5 rotates accordingly, the driving gear 6 rotates therewith, and the driven gear 8 also rotates. The second rotating rod 7 and the roller 9 also rotate. When the roller 9 rotates, oil will splash out, and the oil absorbing plate 10 will absorb some oil. When the oil absorbing plate 10 absorbs too much, its oil absorbing ability will decline. At this time, take out the limiting bolt 12 from the limiting hole 11, so that the limiting bolt 12 will no longer limit the oil absorbing plate 10, and then take down the oil absorbing plate 10 and replace it with a new one, which makes it much easier for the staff to replace. When the roller 9 rotates, the blower 16 can also be turned on. The blower 16 has a large suction force and can suck the splashed oil into the hollow horizontal plate 13. The oil will be blocked by the filter plate 20 to prevent the oil from entering the blower 16. When the filter plate 20 gets dirty, it can be taken out from the first groove 19, which is convenient for the staff to clean.

[0041] Refer to Figure 2 and Figure 3, the clamping mechanism 2 includes a U-shaped groove 201 which is opened at the top of the workbench 1. A second motor 202 is fixedly connected to the rear side of the workbench 1. The output end of the second motor 202 penetrates through the workbench 1 and is fixedly connected to a rotating shaft 203. Active bevel gears 204 are fixedly connected to both ends of the rotating shaft 203. The front and rear sides inside the U-shaped groove 201 are both rotatably connected to threaded rods 205. Driven bevel gears 206 are fixedly connected to the bottom ends of the two threaded rods 205. The two driven bevel gears 206 are respectively meshed and connected with the corresponding active bevel gears 204. Moving blocks 207 are threadedly connected to the outer walls of the two threaded rods 205. A same backing plate 208 is fixedly connected to the adjacent sides of the two moving blocks 207. The left and right sides of the top of the backing plate 208 are both slidably connected with moving plates 209. Fixing bolts 210 are rotatably connected to the right sides of the two moving plates 209. A plurality of fixing holes 211 are equidistantly opened on the right side of the top of the backing plate 208. A cross bar 26 is fixedly connected to the top of the workbench 1. A fixing column 27 is fixedly connected to the bottom of the cross bar 26. A pressing plate 28 is slidably connected to the outer wall of the fixing column 27;

[0042] Specifically, when the paper is fed into the printer by the upper roller 9, the height of the paper drops, and the roller 9 can no longer feed the paper. At this time, the switch 25 is turned on to make the second motor 202 start working. It will drive the rotating shaft 203 to rotate, and the active bevel gear 204 will also start to rotate, then drive the driven bevel gear 206 and the threaded rod 205 to rotate together. In this way, the moving block 207 will move up and down accordingly, and the backing plate 208 will also move upward with the moving block 207, so that the paper can be lifted, facilitating the roller 9 to continue feeding the paper into the printer.

[0043] Refer to Figure 3 , limit blocks 17 are fixedly connected to the left and right sides of one end of a plurality of oil suction plates 10. Limit grooves 18 are opened on the left and right sides inside the two hollow boxes 3. The plurality of limit blocks 17 are respectively slidably arranged inside the corresponding limit grooves 18. Support feet 23 are fixedly connected to the four corners at the bottom of the workbench 1. Rubber pads 24 are fixedly connected to the bottoms of the plurality of support feet 23;

[0044] Specifically, the limit blocks 17 and the limit grooves 18 facilitate placing the oil suction plates 10 in fixed positions without deviation. The support feet 23 and the rubber pads 24 can make the workbench 1 more stable during operation.

[0045] Refer to Figure 1 and Figure 4 , sliding grooves 21 are opened on the left and right sides of the top of the backing plate 208. Sliding blocks 22 are slidably connected to the interiors of the two sliding grooves 21. The plurality of sliding blocks 22 are respectively fixedly connected to the left and right sides of the bottoms of the corresponding moving plates 209. A switch 25 is fixedly connected to the left front end of the workbench 1. The switch 25 is electrically connected to the first motor 4 and the second motor 202 respectively;

[0046] Specifically, the sliding groove 21 and the sliding block 22 can facilitate the more stable movement of the moving plate 209 on the backing plate 208, and the switch 25 can freely control the operation of the first motor 4 and the second motor 202.

[0047] Working principle: When using the four-color printer that prevents oil splashing and pollution, the paper needs to be placed on the backing plate 208 first. At this time, turn on the switch 25 to make the first motor 4 work to drive the first rotating rod 5 to rotate, so that the two driving gears 6 rotate to drive the driven gear 8 to rotate. At the same time, the second rotating rod 7 and the roller 9 rotate accordingly. At this time, part of the oil splashed when the roller 9 rotates is absorbed by the oil absorption plate 10. At the same time, when the oil absorption plate 10 absorbs too much, its absorption capacity becomes poor. At this time, take out the limit bolt 12 from the limit hole 11, so that the limit bolt 12 cancels the limit on the oil absorption plate 10. At this time, take out the oil absorption plate 10 downward for replacement, which is convenient for the staff to operate. At the same time, when the roller 9 rotates, the blower 16 can also be turned on to generate suction, so that the splashed oil is attracted by the suction generated by the blower 16 and enters the hollow cross plate 13 through the connecting plate 14. At this time, the oil will be adsorbed by the filter plate 20 to prevent the oil from entering the blower 16. At the same time, the filter plate 20 can be taken out through the first groove 19, which is convenient for the staff to clean the filter plate 20. And after the paper on the top is conveyed into the printer by the rotation of the roller 9, the height of the paper will decrease, so that the roller 9 can no longer convey the paper into the printer. At this time, turn on the switch 25 to make the second motor 202 work to drive the rotating shaft 203 to rotate, so that the driving bevel gear 204 rotates, and the driven bevel gear 206 and the threaded rod 205 rotate accordingly. At the same time, the moving block 207 moves up and down. At this time, the backing plate 208 moves up with the moving block 207, so that the paper moves up to facilitate the roller 9 to convey the paper into the printer.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
