[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-5 As shown, an ink uniformity control device for ink conveying rollers includes a support frame 1, a plurality of conveying rollers 2 are arranged inside the support frame 1, a first motor 3 is fixedly installed on the right side of the support frame 1, an ink roller 4 is fixedly connected to the output shaft of the first motor 3, an ink cartridge 5 is fixedly connected to the middle of the inner wall of the back of the support frame 1, a collection box 6 is placed on the inner bottom wall of the support frame 1, an adjustment mechanism 7 is provided on the support frame 1, and a feeding mechanism 8 is provided on the support frame 1. The adjustment mechanism 7 includes fixed grooves 71 on the left and right sides of the inner wall of the support frame 1. Movable blocks 72 are slidably connected inside the two fixed grooves 71. Pressure rollers 73 are rotatably connected to the two movable blocks 72 on opposite sides. The feeding mechanism 8 includes a housing 81 fixedly connected to the back of the support frame 1. A second motor 82 is fixedly installed on the inner wall of the back of the housing 81, and the output shaft of the second motor 82 is fixedly connected to a rotating shaft 83.

[0020] It should be noted that by setting up the collection box 6, it is convenient to collect excess ink on the ink roller 4.

[0021] like Figures 1-4 As shown, a fixing rod 74 is fixedly connected to the inner bottom wall of the left fixing groove 71, a spring 75 is sleeved on the outside of the fixing rod 74, the outside of the fixing rod 74 is slidably connected to the inside of the left movable block 72, a threaded rod 76 is rotatably connected to the top of the fixing groove 71, a sleeve 77 is threadedly connected to the outside of the threaded rod 76, and the bottom of the sleeve 77 is fixedly connected to the top of the left movable block 72.

[0022] It should be noted that rotating the threaded rod 76 causes the sleeve 77 to move downwards, which in turn causes the movable block 72 to move downwards. This causes the movable block 72 to slide outside the fixed rod 74, thereby squeezing the spring 75. This causes the pressure roller 73 to move downwards and come into close contact with the ink roller 4, thus adjusting the pressure between the pressure roller 73 and the ink roller 4. This ensures that the ink is transferred evenly, resulting in more stable printing quality. The spring 75 provides cushioning, thus protecting the pressure roller 73 and the ink roller 4 and increasing their service life.

[0023] like Figures 1-4 As shown, a movable rod 84 is rotatably connected to the left side of the back of the support frame 1. Pulleys 85 are fixedly connected to the outer side of the rotating shaft 83 and the middle of the movable rod 84. Belts 86 are driven to the outer sides of the two pulleys 85. Movable plates 87 are fixedly connected to the front of the rotating shaft 83 and the movable rod 84. Connecting blocks 88 are fixedly connected to the front of the two movable plates 87. Frames 89 are slidably connected to the outer sides of the two connecting blocks 88. Guide rods 810 are fixedly connected to the opposite sides of the two frames 89. Inkjet printers 811 are fixedly connected to the front of the two frames 89. A stirring assembly 9 is provided on the back of the support frame 1.

[0024] It should be noted that when the second motor 82 is started, the output shaft of the second motor 82 drives the rotating shaft 83 to rotate. The rotating shaft 83 drives the movable rod 84 to rotate through the pulley 85 and the belt 86, thereby driving the two movable plates 87 to rotate. The movable plates 87 drive the connecting block 88 to rotate, thereby causing the frame 89 to move left and right, thereby driving the two inkjet printers 811 to reciprocate left and right, and thus spraying the ink evenly into the ink cartridge 5.

[0025] like Figures 1-4 As shown, sliding through holes are provided on both the left and right sides of the support frame 1, and the outer side of the guide rod 810 is slidably connected to the inner wall of the sliding through hole.

[0026] It should be noted that by setting guide rod 810 and sliding through hole, the frame 89 is limited and supported, which increases the stability of the frame 89 when it moves.

[0027] like Figures 1-5 As shown, the stirring assembly 9 includes a storage tank 91 fixedly connected to the back of the support frame 1. A feed pipe 92 is fixedly connected to the right side of the storage tank 91. A pump body 93 is fixedly installed on the back of the support frame 1. A suction pipe 94 is fixedly connected to the back of the pump body 93. A discharge pipe 95 is fixedly connected to the front of the pump body 93. A telescopic hose 96 is fixedly connected to one end of the discharge pipe 95. A stirring shaft 97 is rotatably connected to the top of the storage tank 91. A first bevel gear 98 is fixedly connected to the top of the stirring shaft 97. A second bevel gear 99 is fixedly connected to the outer rear side of the rotating shaft 83. The outer side of the first bevel gear 98 meshes with the outer side of the second bevel gear 99.

[0028] It should be noted that when the pump body 93 is started, the pump body 93 draws in the ink through the suction pipe 94, and then discharges it through the discharge pipe 95 and the telescopic hose 96 into the interior of the two inkjet printers 811 for ejection. At the same time, the rotating shaft 83 drives the second bevel gear 99 to rotate, the second bevel gear 99 drives the first bevel gear 98 to rotate, and the first bevel gear 98 drives the stirring shaft 97 to rotate, thereby facilitating the stirring of the ink and thus preventing ink sedimentation.

[0029] like Figures 1-5 As shown, one end of the suction tube 94 passes through and extends into the interior of the storage tank 91, and the left and right sides of the telescopic hose 96 are fixedly connected to the opposite sides of the two inkjet printers 811, respectively.

[0030] It should be noted that the telescopic hose 96 allows for easy left and right movement of the inkjet printer 811.

[0031] like Figures 1-5 As shown, the inner bottom wall of ink cartridge 5 is inclined.

[0032] It should be noted that this facilitates the flow of ink from inside ink cartridge 5 onto ink roller 4.

[0033] The working principle of this utility model is as follows: By setting an adjustment mechanism, rotating the threaded rod 76 causes the sleeve 77 to move downwards, which in turn causes the movable block 72 to move downwards. This causes the movable block 72 to slide outside the fixed rod 74, thereby squeezing the spring 75 and causing the pressure roller 73 to move downwards and make close contact with the ink roller 4. This adjusts the pressure between the pressure roller 73 and the ink roller 4, ensuring uniform ink transfer and stable printing quality. The spring 75 provides cushioning, protecting the pressure roller 73 and the ink roller 4 and increasing their service life. Ink is poured into the storage tank 91 through the feed pipe 92. The pump body 93 is started, drawing in ink through the suction pipe 94 and then discharging it through the discharge pipe 95 and the telescopic hose 96. The ink is ejected into the interior of the two inkjet printers 811, and simultaneously the second motor 82 is activated. The output shaft of the second motor 82 drives the rotating shaft 83 to rotate. The rotating shaft 83 drives the movable rod 84 to rotate through the pulley 85 and the belt 86, thereby driving the two movable plates 87 to rotate. The movable plates 87 drive the connecting block 88 to rotate, thereby causing the frame 89 to move left and right. By setting the guide rod 810 and the sliding through hole, the frame 89 is limited and supported, increasing the stability of the frame 89 during movement, thereby driving the two inkjet printers 811 to reciprocate left and right, thus evenly spraying the ink into the interior of the ink cartridge 5. The rotating shaft 83 simultaneously drives the second bevel gear 99 to rotate, the second bevel gear 99 drives the first bevel gear 98 to rotate, and the first bevel gear 98 drives the stirring shaft 97 to rotate, thereby facilitating the stirring of the ink and preventing ink sedimentation.
