Description

Technical Field

[0001] The present application relates to the technical field of ink control, and in particular to a centralized control system for ink of a printing press. Background Art

[0002] A printing press is a machine that prints text and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, pressing, and paper feeding (including folding).

[0003] Currently available printing equipment is usually equipped with multiple monochrome printing mechanisms, each of which is responsible for printing one color.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the consumption of inks of different colors is different. Once the ink of a certain color is consumed, the device will automatically stop running. At this time, the materials that are printing other color blocks and the materials that are printing the color blocks with missing colors will become defective products, which will affect the quality of the printed products. Summary of the Invention

[0005] In order to improve the quality of printed products, the present application provides a centralized control system for printing ink.

[0006] The printing press ink centralized control system provided in this application adopts the following technical solutions:

[0007] The centralized control system of printing ink includes a machine body and a monochrome printing mechanism, an ink cartridge is provided on the top of the monochrome printing mechanism, an ink box is provided on one side of the monochrome printing mechanism, a feed bin is fixedly provided near the edge line on the upper surface of the ink box, an ink inlet is penetrated through the side wall on one side of the feed bin, an ink inlet tube is fixedly connected between the ink box and the ink cartridge, the ink inlet tube connects the interior of the ink box and the ink inlet, an ink outlet is penetrated through the bottom of the ink cartridge along its own length direction, a baffle is slidably connected to the inner wall of the feed bin on the side facing away from the ink inlet tube in the vertical direction, a floating plate is horizontally provided in the ink box, the floating plate can float on the ink, and an adjustment device for adjusting the height of the baffle is provided between the baffle and the floating plate.

[0008] By adopting the above technical solution, the position of the float plate moves with the ink level in the ink cartridge. When the ink in the ink cartridge is too low, the float plate descends, and the adjustment device moves the baffle away from the ink inlet, thereby opening the ink inlet and allowing the ink in the ink tank to enter the ink cartridge. When the ink in the ink cartridge is fully replenished, the float plate ascends, and the adjustment device moves the baffle over the ink inlet, thereby closing the ink inlet and suspending the flow of ink from the ink tank into the ink cartridge. With this structure, when the ink in the ink cartridge is low, ink can be automatically replenished, making it less likely that the ink in the ink cartridge will be completely depleted, thereby reducing the risk of defective products caused by insufficient ink, and thus improving the quality of printed products.

[0009] Optionally, the floating plate and the baffle are located at both ends of the ink cartridge.

[0010] By adopting the above technical solution, when ink enters the ink box through the ink inlet, the ink is not likely to fall onto the upper surface of the float plate and cause the float plate to sink, thereby achieving the effect of the float plate floating on the ink surface.

[0011] Optionally, the adjusting device includes two fixed pulleys and a connecting rope, one fixed pulley is rotatably connected above the baffle, and the other fixed pulley is rotatably connected above the floating plate, one end of the connecting rope is fixedly connected to the top wall of the baffle, and the other end of the connecting rope passes through the upper surface of the ink cartridge and is fixedly connected to the upper surface of the floating plate, and the connecting rope passes around the two fixed pulleys.

[0012] By adopting this technical solution, the floating plate descends, causing the connecting rope to drive the baffle plate upward, thereby opening the ink inlet. When the floating plate ascends, the baffle plate descends due to its own gravity, thereby closing the ink inlet. This structure achieves the effect of controlling the opening and closing of the ink inlet.

[0013] Optionally, first protrusions are fixedly provided on the side walls on both sides of the floating plate, and a first groove slidably fitted with the first protrusion is vertically formed on the inner wall of the ink cartridge facing the first protrusion.

[0014] By adopting the above technical solution, the floating plate moves so that the first protrusion moves along the first groove, thereby achieving an effect of improving the stability of the floating plate when it moves.

[0015] Optionally, the side walls on both sides of the baffle are fixed with second protrusions, and the inner wall of the ink cartridge facing the second protrusions is provided with a second groove that is slidably fitted with the second protrusions.

[0016] By adopting the above technical solution, when the baffle covers the ink inlet, it is not easily squeezed and moved by the ink in the ink inlet tube; during the movement of the baffle, the second protrusion moves along the second groove. This structure achieves the effect of limiting the position of the baffle and stabilizing the baffle during movement.

[0017] Optionally, a through hole is formed through the side wall of the baffle near the top, a mounting plate is fixedly provided on the top of the monochrome printing mechanism, a first cross bar and a second cross bar are horizontally provided on the side wall of the mounting plate facing the ink cartridge, the second cross bar is plugged into and adapted for the through hole, and the second cross bar is provided as an inclined surface on the side facing the baffle, a notch is formed through the side wall of the baffle near the top, the first cross bar passes through the notch, a connecting rod is fixedly connected to the first cross bar and the second cross bar near one end of the mounting plate, a spring is fixed between the connecting rod and the mounting plate, and a pushing device for moving the first cross bar is provided on the side of the first cross bar away from the connecting rod.

[0018] By adopting this technical solution, when the baffle rises, its top edge presses against the inclined surface of the second crossbar, which in turn presses against the spring. When the second crossbar aligns with the through-hole, the spring releases its elastic force, allowing the second crossbar to engage with the through-hole. When the floating plate rises, the floating plate uses the pushing device to press against the first crossbar, thereby compressing the spring and disengaging the second crossbar from the through-hole. The baffle then falls under its own gravity until it covers the ink inlet. With this structure, the baffle only descends after the floating plate has risen to the designated position, delaying the closure of the ink inlet and ensuring sufficient ink replenishment within the ink cartridge.

[0019] Optionally, the pushing device includes a third cross bar, a hinged rod and a push rod, the third cross bar moves back and forth in the direction toward the first cross bar, the bottom end of the push rod is fixedly connected to the upper surface of the floating plate, the upper surface of the ink cartridge is penetrated by a avoidance opening for the push rod to pass through, the hinged rod is tilted, the top of the hinged rod is hinged to the end of the third cross bar away from the first cross bar, and the bottom of the hinged rod is located directly above the avoidance opening.

[0020] By adopting the above technical solution, the floating plate rises, causing the push rod to rise, thereby causing the push rod to drive the hinged rod to move, and the hinged rod squeezes the first cross bar through the third cross bar, thereby achieving the effect of the pushing device moving the position of the first cross bar.

[0021] Optionally, the circumferential side wall of the third crossbar is slidably connected to a guide sleeve along the horizontal direction, and a support rod is fixed between the bottom of the guide sleeve and the upper surface of the ink cartridge.

[0022] By adopting the above technical solution, the third crossbar slides along the length direction of the guide sleeve, and the guide sleeve guides the third crossbar, thereby achieving a smooth movement of the third crossbar.

[0023] Optionally, a socket adapted to be plugged into the push rod is provided at the bottom of the other end of the hinged rod.

[0024] By adopting the above technical solution, after the push rod rises to be plugged into and adapted to the socket, it drives the articulated rod to move, thereby achieving the effect of the push rod driving the articulated rod to move smoothly.

[0025] Optionally, a support frame is fixedly provided on the upper surface of the ink cartridge, and the top of the support frame abuts against the hinge rod.

[0026] By adopting the above technical solution, the support frame supports the hinged rod.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the ink in the ink cartridge is too low, the float plate, through the adjustment device, causes the baffle to open the ink inlet, allowing the ink in the ink box to flow into the ink cartridge. When the ink in the ink cartridge is fully replenished, the float plate, through the adjustment device, causes the baffle to close the ink inlet. With this structure, when the ink in the ink cartridge is low, ink can be automatically replenished, which reduces the risk of defective products due to ink depletion, thereby improving the quality of printed products.

[0029] 2. The baffle rises, squeezing the inclined surface. Once the second crossbar is aligned with the through-hole, it engages and fits into the through-hole. The floating plate rises, squeezing the first crossbar through the pushing mechanism, causing the second crossbar to disengage from the through-hole. The baffle then descends under its own gravity until it covers the ink inlet. With this structure, the baffle only descends after the floating plate reaches the designated position, ensuring sufficient ink replenishment in the ink cartridge.

[0030] 3. The floating plate drives the hinged rod to move through the push rod, and the hinged rod squeezes the first cross bar through the third cross bar, thereby achieving the effect of the pushing device moving the position of the first cross bar. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] The embodiments of the present application disclose a centralized control system for printing ink.

In the embodiment of the present application, there are six monochrome printing mechanisms 2. An ink cartridge 3 is fixed on the top of the monochrome printing mechanism 2. An ink box 4 is provided on one side of each monochrome printing mechanism 2. An ink inlet tube 312 is connected between the ink box 4 and the ink cartridge 3. An oil pump 3121 is installed on the ink inlet tube 312 above the ink box 4.

[0041] When the ink in the ink cartridge 3 is insufficient, the ink in the ink box 4 is replenished into the ink cartridge 3 through the oil pump 3121 and the ink inlet tube 312 , thereby achieving the effect of automatically replenishing the ink in the ink cartridge 3 .

[0042] refer to Figure 1 and Figure 2 A feed bin 31 is fixedly provided at the top of the ink cartridge 3 near one end of the ink box 4. The bottom of the feed bin 31 is connected to the ink cartridge 3. An ink inlet 311 is penetrated through one side of the feed bin 31 near the ink box 4. An ink inlet tube 312 is connected to the ink inlet 311. An ink outlet 32 ​​is provided at the bottom of the ink cartridge 3 along its own length direction. A brush 321 is fixedly provided at the ink outlet 32 ​​of the ink cartridge 3.

[0043] When the ink in the ink cartridge 3 is insufficient, the ink in the ink box 4 flows through the ink inlet 311 via the ink inlet tube 312 and into the ink cartridge 3, thereby replenishing the ink in the ink cartridge 3. The ink in the ink cartridge 3 flows from the ink outlet 32 ​​to the brush 321, and the ink falls into the monochrome printing mechanism 2 through the brush 321.

[0044] refer to Figure 2 and Figure 3 A floating plate 6 is horizontally arranged inside the ink cartridge 3, and first protrusions 61 are fixedly provided on the side walls on both sides of the floating plate 6. First grooves 33 are opened along the vertical direction on the inner walls on both sides of the ink cartridge 3. The first protrusions 61 are embedded in the first grooves 33, and the first protrusions 61 are slidably connected to the inner wall of the ink cartridge 3 along the length direction of the first grooves 33.

[0045] refer to Figure 2 and Figure 4 A baffle 5 for blocking the ink inlet 311 is slidably connected to the inside of the feed bin 31 in the vertical direction. The baffle 5 and the float 6 are located at both ends of the ink cartridge 3. The side walls on both sides of the baffle 5 are fixed with second protrusions 51. The inner wall of the ink cartridge 3 facing the second protrusion 51 is provided with a second groove 34.

[0046] refer to Figure 2 and Figure 4 An adjusting device 7 for adjusting the position of the baffle 5 is provided between the top wall of the baffle 5 and the upper surface of the floating plate 6. The adjusting device 7 includes two fixed pulleys 71 and a connecting rope 72. Two fixed frames are fixed on the upper surface of the monochrome printing mechanism 2, one of which is located above the baffle 5, and the other fixed frame is located above the floating plate 6. The two fixed pulleys 71 are rotatably connected to the middle position of the top of the two fixed frames, one end of the connecting rope 72 is fixedly connected to the top wall of the baffle 5, and the other end of the connecting rope 72 passes through the upper wall of the ink cartridge 3 and is fixedly connected to the upper surface of the floating plate 6, and the connecting rope 72 passes around the two fixed pulleys 71.

[0047] When the ink in the ink cartridge 3 is insufficient, the float 6 drops as the ink liquid level decreases. At this time, the first protrusion 61 slides along the first groove 33, and the float 6 moves around the fixed pulley 71 through the connecting rope 72, thereby driving the baffle 5 to rise above the ink inlet 311. At this time, the second protrusion 51 slides along the second groove 34, thereby opening the ink inlet 311, and the ink in the ink box 4 is replenished into the ink cartridge 3.

[0048] refer to Figure 2 and Figure 4A mounting plate 8 is fixedly provided on the upper surface of the monochrome printing mechanism 2, and a first cross bar 81 and a second cross bar 82 are horizontally provided on the side wall of one side of the mounting plate 8. The first cross bar 81 and the second cross bar 82 are at the same horizontal height, and the side wall of the first cross bar 81 facing the baffle 5 is set to an inclined surface 821, and the first cross bar 81 and the second cross bar 82 are fixed with a connecting rod 83 near one end of the mounting plate 8. The first cross bar 81, the second cross bar 82 and the connecting rod 83 are an integrally formed structure, and a spring 84 is fixed between the connecting rod 83 and the mounting plate 8; a through hole 52 is penetrated through the side wall of the baffle 5 to be clamped and adapted to the second cross bar 82, and a notch 53 is penetrated through the side wall of the baffle 5 near the top, and the notch 53 penetrates the top wall of the baffle 5, and the first cross bar 81 passes through the notch 53.

[0049] refer to Figure 2 and Figure 5 A pushing device 9 is provided on the side of the first cross bar 81 away from the mounting plate 8. The pushing device 9 includes a third cross bar 91, a hinged rod 92 and a push rod 93. A support rod 912 is fixed on the upper surface of the ink cartridge 3 on the side of the first cross bar 81 away from the mounting plate 8. A guide sleeve 911 is fixed on the top of the support rod 912. The third cross bar 91 is set in the guide sleeve 911, and the third cross bar 91 is slidably connected to the guide sleeve 911 along the length direction of the guide sleeve 911 itself. The ink cartridge 3 A support frame 922 is fixed to the upper surface on the side of the support rod 912 away from the mounting plate 8, the hinged rod 92 is arranged at an angle, one end of the hinged rod 92 is hinged to the end of the third cross bar 91 away from the first cross bar 81, and the other end of the hinged rod 92 is in contact with the support frame 922, the push rod 93 is fixed to the upper surface of the floating plate 6, and an avoidance opening 35 for the push rod 93 to pass through is opened through the upper surface of the ink cartridge 3, and a socket 921 adapted for plugging with the push rod 93 is opened at the bottom of the hinged rod 92.

[0050] During the rising process of the baffle 5, the top of the baffle 5 presses the inclined surface 821 of the second cross bar 82, and the second cross bar 82 compresses the spring 84 through the connecting rod 83. When the second cross bar 82 is aligned with the through hole 52, the spring 84 releases the elastic force to make the second cross bar 82 engage with the through hole 52. At the same time, the first cross bar 81 passes through the notch 53. At this time, the ink in the ink box 4 enters the ink cartridge 3, and the ink level in the ink cartridge 3 rises and drives the float 6 to move upward. At this time, the second cross bar 82 and the baffle 5 are still in the engaged state, so the height of the baffle 5 does not change. The baffle 5 descends until the float 6 drives the push rod 93 through the avoidance opening 35 and contacts the hinge rod 92. The push rod 93 then engages with the insertion hole 921. The push rod 93 then drives the hinge rod 92 to move and leave the support frame 922. The hinge rod 92 drives the third cross bar 91 to slide along the guide sleeve 911. The third cross bar 91 presses the first cross bar 81. The first cross bar 81 compresses the spring 84 via the connecting rod 83. At the same time, the connecting rod 83 drives the second cross bar 82 to disengage from the through hole 52. The baffle 5 falls due to its own gravity until it covers the ink inlet 311. Through the above structure, the ink inlet 311 is delayed in closing, thereby allowing sufficient time for the ink in the ink cartridge 3 to be replenished.

[0051] refer to Figure 6 An ink return tube 41 is connected between the ink inlet tube 312 and the ink box 4 , and a connection between the ink return tube 41 and the ink inlet tube 312 is located above the ink inlet tube 312 .

[0052] When the baffle 5 covers the ink inlet 311 , the ink pumped into the ink inlet pipe 312 by the oil pump 3121 will flow toward the ink return pipe 41 , and then flow into the ink tank 4 through the ink return pipe 41 .

[0053] The implementation principle of the printing press ink centralized control system in the embodiment of the present application is: the float plate 6 rises or falls as the ink liquid level changes, and the float plate 6 drives the first protrusion 61 to slide along the first groove 33. At the same time, the float plate 6 moves around the fixed pulley 71 through the connecting rope 72 to drive the baffle 5 to rise or fall, and the baffle 5 drives the second protrusion 51 to slide along the second groove 34. The ink in the ink cartridge 3 decreases with the use of the monochrome printing press, and the float 6 drops as the liquid level drops, driving the baffle 5 to rise. During the rising process of the baffle 5, the top of the baffle 5 squeezes the inclined surface 821 to compress the second cross bar 82 on the spring 84, so that the second cross bar 82 is engaged with the through hole 52, thereby opening the ink inlet 311 and replenishing the ink in the ink box 4 into the ink cartridge 3; the ink liquid level in the ink cartridge 3 rises as the ink is replenished, and the float 6 drives the push rod 93 to rise to the required position as the liquid level rises, and the push rod 93 passes through the avoidance opening 35 and is plugged into the socket 921 for adaptation, and then the push rod 93 drives the third cross bar 91 to slide along the guide sleeve 911 through the hinged rod 92, and the third cross bar 91 squeezes the first cross bar 81, so that the first cross bar 81 compresses the spring 84 through the connecting rod 83, so that the second cross bar 82 is separated from the through hole 52, and the baffle 5 falls due to its own gravity until it covers the ink inlet 311. With the above structure, when the ink in the ink cartridge 3 is insufficient, the ink in the ink box 4 is automatically replenished into the ink cartridge 3, thereby achieving the effect of improving the quality of printed products.

[0054] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
