[0019] Embodiment:

[0020] Please refer to Figures 1 - 3 , the present utility model provides a technical solution:

[0021] A carton printing paper feeding control mechanism includes a base 1. At one end of the top of the base 1, a limiting mechanism is installed. In the center of the top of the base 1, a conveyor 2 is embedded. At the bottom corners of the base 1, support feet are installed. A dust suction and recycling mechanism is installed on the limiting mechanism. The dust suction and recycling mechanism includes an adjustment component, a sweeping and dust suction component, and a spraying and discharging component. The sweeping and dust suction component is used to sweep and suck the dust and impurities on the printing surface of the cardboard. The spraying and discharging component is used to perform dust reduction treatment on the collected dust and impurities and centrally discharge the recycled impurities. The adjustment component is used to adjust the position of the sweeping and dust suction component. When the device is in use, the cardboard can be placed on the conveyor 2 for transportation, and then the movement area of the cardboard is restricted by the limiting mechanism. Subsequently, the sweeping and dust suction component is used to absorb the swept dust and impurities. Then, the spraying and discharging component is used to perform dust reduction on the dust and impurities and then discharge them. The structure is simple and the operation is convenient, which is convenient for the staff to clean the impurities on the cardboard surface and ensures the subsequent printing effect.

[0022] In this embodiment, as Figure 1 shown, the adjustment component includes a mounting post 3 installed on the limiting mechanism. At the top end of the mounting post 3, an adjustment groove is opened. Inside the adjustment groove, a first threaded rod 4 is rotatably connected. On the outer side of the first threaded rod 4, an adjustment frame 5 is threadedly connected. The adjustment frame 5 is slidably connected to the adjustment groove. At one end of the mounting post 3, a first motor 6 is installed. The driving end of the first motor 6 extends to the inside of the adjustment groove and is fixedly connected to one end of the first threaded rod 4. First, the movement area of the cardboard is restricted by the limiting mechanism. Then, the first motor 6 is started to drive the first threaded rod 4 to rotate, so that the adjustment frame 5 moves horizontally along the inside of the adjustment groove, enabling the dust suction head 15 to reciprocally suck impurities and the soft brush 24 to reciprocally brush the dust.

[0023] In this embodiment, as Figure 1 and Figure 3 shown, the sweeping and dust suction component includes a suction pump 12 installed at one end of the top of the adjustment frame 5. At the suction end of the suction pump 12, a suction pipe is installed. The other end of the suction pipe is installed with a suction cylinder 13 extending into the inside of the recycling box 7. An installation frame 14 is clamped on the suction cylinder 13 through a clamping component. A dust-proof net is installed inside the installation frame 14. At the other end of the recycling box 7, a connecting pipe extending into the inside of the adjustment frame 5 is installed. At the bottom end of the connecting pipe, multiple groups of branch pipes are arranged and installed. At the bottom end of the branch pipes, dust suction heads 15 are installed. At one end of the adjustment frame 5, a mounting rod is installed. At the bottom end of the mounting rod, a soft brush 24 is installed. A second valve is installed on the suction cylinder 13. Then, when the cardboard is being conveyed, the suction pump 12 is started, so that the dust and impurities are sucked into the inside of the recycling box 7 along the dust suction heads 15, branch pipes and connecting pipe. At the same time, the dust-proof net intercepts the impurities to prevent them from entering the suction pump 12. The soft brush 24 can also gently sweep the dust on the surface of the cardboard during the transportation of the cardboard, facilitating the subsequent suction by the dust suction heads 15.

[0024] In this embodiment, as Figure 1and Figure 3 As shown in the figure, the spray discharge assembly includes a recovery tank 7 installed at one end of the top of the adjustment frame 5. A water storage tank 8 is installed at the top end of the recovery tank 7. A water inlet pipe 9 is embedded and installed at the top end of the water storage tank 8. A water delivery pipe extending to the inside of the recovery tank 7 is embedded and installed on one side of the water storage tank 8. An electromagnetic valve 10 is installed on the water delivery pipe. A discharge pipe is embedded and installed on one side of the recovery tank 7. A first valve 11 is installed on the discharge pipe. Further, after impurities and dust are sucked into the inside of the recovery tank 7, the electromagnetic valve 10 is started to make the water source pour into the inside of the recovery tank 7 through the water delivery pipe, mix with the floating dust and fine impurities, and achieve dust reduction. Then, the first valve 11 is opened to guide the sewage to the discharge pipe for discharge, avoiding the dust floating in the air when discharged and being inhaled by personnel, which may affect the body. And when the electromagnetic valve 10 is opened for spraying water, the second valve can be closed to prevent the water source from flowing back into the inside of the suction pump 12.

[0025] In this embodiment, as Figure 1 shown, the limiting mechanism includes a fixed frame 16 installed at one end of the top of the base 1. A second threaded rod 17 is rotatably connected inside the fixed frame 16. The threads on the left and right sides of the center of the second threaded rod 17 are opposite. Limiting plates 18 are threadedly connected to both ends of the second threaded rod 17. A plurality of limiting rollers 19 are rotatably connected to the bottom ends of the limiting plates 18. The bottom end of the mounting column 3 is fixedly connected to the top end of one of the limiting plates 18. A limiting groove is opened at the bottom end inside the fixed frame 16. The limiting plate 18 is slidably connected to the limiting groove. A second motor is installed on one side of the fixed frame 16. The driving end of the second motor penetrates the fixed frame 16 and is fixedly connected to one end of the second threaded rod 17. Further, the second motor is started to drive the second threaded rod 17 to rotate, so that the two limiting plates 18 slide along the inside of the limiting groove, and the limiting rollers 19 on both sides approach the edge of the cardboard for limiting. When the cardboard contacts the limiting rollers 19, it will also rotate accordingly, without interfering with the transportation process.

[0026] In this embodiment, as Figure 1 and Figure 2As shown, the clamping component includes a docking groove opened at one end of the top of the suction cylinder 13. The mounting bracket 14 is snap-connected to the docking groove. Pressing grooves are opened at both ends of the inner wall of the docking groove. At both ends of the bottom of the mounting bracket 14, pressing blocks 20 snap-connected to the pressing grooves are installed. An extrusion groove is opened inside the suction cylinder 13 on one side of the pressing groove. An extrusion plate 21 is slidably connected to the inner side of the extrusion groove. First springs 22 are installed between both ends of one side of the extrusion plate 21 and the inner wall of the extrusion groove. A pull rod is installed between the two first springs 22 on one side of the extrusion plate 21. The pull rod is slidably connected to the suction cylinder 13. One end of the pull rod extending outside the suction cylinder 13 is installed with a pull plate 23. A pull ring is installed at one end of the pull plate 23. A buckle pulling groove is opened at the top end of the mounting bracket 14. The cross section of the pressing block 20 is L-shaped, and the cross section of the extrusion plate 21 is T-shaped. Slopes that fit each other are opened at the opposite ends of the pressing block 20 and the extrusion plate 21. Further, when the pressing block 20 is pressed into the groove, the slope of the pressing block 20 presses the slope of the extrusion plate 21, causing the extrusion plate 21 and the first spring 22 to retract. After the pressing block 20 is completely inserted, the extrusion plate 21 pops out and abuts, completing the assembly of the dust filter screen. On the contrary, pulling the pull ring drives the pull plate 23 and the pull rod to move, and the extrusion plate 21 retracts again. At this time, by buckling the buckle pulling groove, the mounting bracket 14 and the dust filter screen can be lifted, facilitating personnel to clean the dust filter screen.

[0027] The implementation principle of a paper feeding control mechanism for printing on a carton in an embodiment of the present application is as follows: a limiting mechanism is used to limit the movement area of ​​the cardboard, and then the first motor 6 is started to drive the first threaded rod 4 to rotate, so that the adjustment frame 5 moves horizontally along the inner side of the adjustment slot, so that the dust suction head 15 can reciprocate to absorb impurities, and the soft brush 24 can reciprocate to brush the dust, and the suction pump 12 is started when the cardboard is being transported, so that dust and impurities are sucked into the inner side of the recycling box 7 along the dust suction head 15, the branch pipe and the connecting pipe, and at the same time, the dustproof net intercepts the impurities to prevent them from entering the suction pump 12, and the soft brush 24 can also gently sweep the dust on the surface of the cardboard when it is transported, so that the rear dust suction head 15 can absorb it, and after the impurities and dust are sucked into the inner side of the recycling box 7, the solenoid valve 10 is started to allow the water source to be poured into the inner side of the recycling box 7 through the water pipe, and mixed with the flying dust and fine impurities to achieve dust reduction, and then the first valve 11 is opened to guide the sewage to The second valve can be closed when the solenoid valve 10 is opened to spray water to prevent the water from flowing back to the inside of the suction pump 12, and the second motor can be started to drive the second threaded rod 17 to rotate, so that the two sets of limit plates 18 slide along the inside of the limit groove, so that the limit rollers 19 on both sides are close to the edge of the cardboard for limit, and the cardboard will rotate when it contacts the limit rollers 19, which will not hinder the transportation process, and the pressing block 20 is pressed into the inside of the groove, and the inclined surface of the pressing block 20 presses the inclined surface of the extrusion plate 21, so that the extrusion plate 21 and the first spring 22 retract, and after the pressing block 20 is completely entered, the extrusion plate 21 pops out and abuts, completing the assembly of the dustproof net, on the contrary, pulling the pull ring drives the pull plate 23 and the pull rod to move, and the extrusion plate 21 is retracted again. At this time, buckling the pull groove can drive the mounting frame 14 and the dustproof net to rise, which is convenient for personnel to clean the dustproof net.
