Description

Technical Field

[0001] The invention relates to the technical field of printing mechanisms, in particular to a printing mechanism for preventing ink from solidifying. Background Art

[0002] Digital printing equipment can complete a large number of printing tasks in a short time through computer control, without the need for tedious steps such as plate making and plate exposure, thus greatly shortening the production cycle. This high efficiency makes digital printing equipment excellent in quickly responding to market demands and meeting urgent orders.

[0003] In the announcement number CN111137014B, titled "Digital Printing Machine with Anti-Ink Solidification Mechanism", it is mentioned that in the field of printing machines, a large number of printed materials need to be printed, and the ink supply pipeline will correspondingly become a large-diameter pipeline due to the pressure requirement. However, when the printing machine is stopped, because the pipeline diameter is relatively large, a lot of ink will remain in the pipeline. If the external temperature is too low, the ink will solidify in a very short time, and the nozzle will be blocked, resulting in waste of ink and the trouble of cleaning when it is used again later.

[0004] Based on the above, the ink is easy to solidify in the pipeline, but the space in the pipeline is relatively small and relatively sealed, and the ink cartridge containing the ink, especially the ink cartridge that can add ink, needs to be connected to the outside world to add ink, so the water in the ink is easy to evaporate, which can easily cause the ink in the ink cartridge to solidify. Based on this, it is necessary to add a professional anti-curing agent to the ink, which can extend the service life of the ink, prevent the ink from solidifying, and avoid the ink cartridge being exposed to the air for a long time, causing the ink to volatilize and dry up. However, when processing the ink that is partially solidified in the ink cartridge, the ink inside needs to be stirred to mix the old ink with the new ink. On this basis, certain improvements are proposed to the solidification of the ink. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 8 The present invention provides a technical solution: the ink cartridge body 4 capable of adding ink needs to be connected to the outside to add ink, so the water in the ink is easy to evaporate, which easily causes the ink in the ink cartridge body 4 to solidify. Under the action of gravity, the solidified ink is at the lower end of the ink cartridge body 4. When cleaning the solidified ink, the ink cartridge body 4 needs to be taken out and then processed. The ink that is easy to solidify needs to be processed. Based on this, a printing mechanism to prevent ink from solidifying is proposed, such as Figure 1 and Figure 2 As shown, the printing device 1 includes an ink chamber 2 disposed on the outside of the printing device 1, an ink cartridge body 4 is installed in the ink chamber 2, an outer cover 3 is disposed on the outer side of the ink chamber 2, an infusion port 41 and an operating unit 5 are disposed on the outer side of the ink cartridge body 4, the ink cartridge body 4 is divided into a plurality of inner chambers 43, each inner chamber 43 is provided with an operating unit 5, the plurality of inner chambers 43 are used to allow the ink cartridge body 4 to accommodate and separate different types of pigments or inks, each inner chamber 43 is designed with an independent ink supply system to ensure that the ink can be evenly and stably supplied to the nozzle, and the inner chambers 43 are separated by sealing materials to prevent color mixing and ink leakage;

[0033] like Figure 4 As shown, the operating part 5 includes a frame 51 located in the inner cavity 43, and an operating shaft 52 is inserted in the frame 51. The operating shaft 52 is used to drive the frame 51 to move in the inner cavity 43 to stir the ink. The frame 51 is used to reciprocate up and down in the inner cavity 43 to achieve ink mixing in the inner cavity 43. The operating shaft 52 is used to drive the frame 51 to move.

[0034] like Figure 4 As shown, the filling port 41 of the ink cartridge body 4 is located obliquely above it and is used to add ink. At the same time, it can also discharge the gas inside the inner cavity 43 during the filling process. The outer side of the ink cartridge body 4 also has a transparent observation layer 42. The observation layer 42 is used to observe the state of the ink in the inner cavity 43. The main function of the observation layer 42 is to observe the state of the ink. When the frame 51 reciprocates up and down, the state of ink flow can be seen intuitively, avoiding the solidification of the internal ink, and even if it is solidified, it can be discovered in time.

[0035] like Figure 6 As shown, the sides of the frame 51 are connected, and through holes 511 for ink movement are provided on the upper and lower sides of the frame 51. The lower end and sides of the frame 51 can fit with the inner wall of the inner cavity 43 to squeeze the ink. When the frame 51 reciprocates up and down, the ink at the upper and lower positions of the frame 51 will be acted upon by force, realizing the jet effect and pumping effect, thereby further mixing the ink.

[0036] like Figure 8 As shown, due to the limited range of up and down movement of the frame 51, it is difficult for the frame 51 to clean the inner wall of the side of the inner cavity 43. For this reason, horizontal cross bars 513 are fixed on both sides of the frame 51. The outer side of the cross bar 513 is in contact with the inner wall of the inner cavity 43. The cross bar 513 is used to clean the inner wall of the side of the inner cavity 43. The cross bar 513 moves up and down with the frame 51, so that the frame 51 can clean the inner wall of the side of the inner cavity 43 during the up and down reciprocating movement.

[0037] like Figure 8As shown, in order to enable the operating shaft portion 52 to drive the frame 51 to reciprocate up and down, the operating shaft portion 52 includes an outer tube shaft 521 for rotating and an inner tube shaft 528 for transmitting ink. A transverse cavity 512 is horizontally penetrated on the frame 51. The length of the transverse cavity 512 is greater than the height. The outer tube shaft 521 is rotatably installed inside the ink cartridge body 4. The outer tube shaft 521 penetrates the transverse cavity 512 and extends out of the ink cartridge body 4. An elliptical end 522 is integrally formed on the outer wall of the outer tube shaft 521. The elliptical end 522 is located in the transverse cavity 512. The elliptical end 522 rotates to control the frame 51 to reciprocate up and down. The elliptical end 522 rotates, and its axis position remains unchanged. The protruding direction of the elliptical end 522 changes. Since the length of the transverse cavity 512 is greater than the height, the elliptical end 522 is an ellipse as a whole, and one end is protruding. The protruding end contacts the upper and lower sides of the transverse cavity 512, so that the transverse cavity 512 moves in the up and down direction, thereby realizing the up and down movement of the frame 51.

[0038] like Figure 8 As shown, the interior of the outer tube shaft 521 is hollow, an inner support spring 523 is fixed at one end of the inner tube shaft 521, an inner blocking shaft 524 is supported at the end of the inner support spring 523, the inner blocking shaft 524 is sleeved in the outer tube shaft 521, an outlet hole 525 is penetrated on the outer side of the outer tube shaft 521, the inner tube shaft 528 is hollow, and is sleeved to the interior of the outer tube shaft 521, an inlet hole 529 is penetrated on the inner tube shaft 528, when the inner blocking shaft 524 is not subjected to the thrust of the inner tube shaft 528, the inner blocking shaft 524 blocks the outlet hole 525, when the inner blocking shaft 524 is subjected to the thrust of the inner tube shaft 528, The outlet hole 525 is connected with the inlet hole 529 and is used to transport ink into the inner cavity 43. The outer tube shaft 521 can open the outlet hole 525, and can directly squeeze the ink inward. The gas inside the inner cavity 43 can move outward from the infusion port 41 at the upper end. In addition, only when the inner tube shaft 528 and the inner blocking shaft 524 are squeezed can the inlet hole 529 be connected with the outlet hole 525, so that the ink at the outer end can be squeezed into the inner cavity 43. When the inner tube shaft 528 and the inner blocking shaft 524 do not cooperate, they are in a blocked state, which is convenient for squeezing the ink in and preventing the internal ink from moving outward.

[0039] like Figure 8 As shown, in order to control the position where the ink is squeezed inward, a surrounding layer 526 is sleeved on the outer side of the outer tube shaft 521, and a hose 527 for transmitting ink is fixed between the surrounding layer 526 and the inner wall of the lower end of the frame 51. The hose 527 transfers the ink to the lower end of the frame 51, so that the newly added ink can move to the lower end of the frame 51 and mix with the old ink more quickly, and the ink at the lower end of the inner cavity 43 can be quickly mixed to avoid solidification as much as possible.

[0040] like Figure 6 and Figure 7As shown, a control unit 53 is provided on the outside of the outer tube shaft 521, and the control unit 53 includes a limiting ring layer 533 fixed on the outside of the outer tube shaft 521, and both sides of the limiting ring layer 533 have sealing rings. Two symmetrical outer support sheets 531 are fixed on the outside of the ink cartridge body 4, and two halves of fixed half layers 532 are sandwiched between the two symmetrical outer support sheets 531. The two halves of the fixed half layers 532 are fixed to each other, and the two halves of the fixed half layers 532 are used to be squeezed with the limiting ring layer 533. The two halves of the fixed half layers 532 can move outward along the outer support sheet 531. The limiting ring layer 533 limits the position of the outer tube shaft 521 passing through the ink cartridge body 4 to avoid ink leakage outward during the rotation process. The fixed half layer 532 is used to support the limiting ring layer 533 to ensure that it is in a sealed state under the action of the sealing ring.

[0041] like Figure 7 As shown, a transmission belt 534 is provided between the multiple groups of operating parts 5, and the transmission belt 534 is sleeved on the outside of two adjacent outer tube shafts 521. A gear 1 535 is fixed to the outside of one of the outer tube shafts 521, and a motor is fixed to the inside of the outer cover 3. A gear 2 536 meshing with the gear 1 535 is fixed to the output end of the motor. The motor is used to drive one outer tube shaft 521 to rotate, and the other outer tube shafts 521 rotate under the action of the transmission belt 534.

[0042] An operation opening 31 is provided on the outer side of the outer cover 3 , and the operation opening 31 is used to observe the ink cartridge body 4 inside.

[0043] Working principle of the present invention: During the printing process, the ink in the ink cartridge body 4 needs to be printed on the paper surface. The ink in the ink cartridge body 4 is located at the lower end of the inner cavity 43 under the action of gravity. The reduction of ink and the gradual reduction of water content in the ink under the influence of the outside world easily cause the ink to solidify at the lower end of the inner cavity 43. In addition, when adding ink again, the ink at the bottom of the inner cavity 43 is difficult to mix with the newly added ink, causing the ink at the lower end of the inner cavity 43 to be in a deposited state. Based on this, the solidified ink is difficult to handle;

[0044] However, through the operation of the operating part 5, the outer tube shaft 521 is rotated, and the elliptical end 522 on the outer tube shaft 521 also rotates, and rotates in the horizontal cavity 512. The size of the horizontal cavity 512 remains unchanged, but the position can be changed, so that the frame 51 reciprocates up and down, wherein the frame 51 moves downward so that its lower end surface is squeezed with the deposited ink, and the ink can move upward along the through hole 511 and mix with the ink inside the inner cavity 43. In addition, the newly added ink at the upper end can also pass through the through hole 511 when the frame 51 moves upward, so that the old ink is mixed with the newly added ink, thereby avoiding the solidification of the old ink. When the frame 51 reciprocates up and down, the ink is continuously moved from the through hole 511 to mix the ink to the greatest extent.

[0045] In addition, during the mixing of ink, the frame 51 fits against the inner cavity 43 to avoid the existence of unprocessed corners in the inner cavity 43. In addition, the inner wall of the side of the inner cavity 43 is scraped by the cross bar 513 to allow the ink that is easy to adhere and has increased viscosity to mix with the new ink, thereby avoiding ink solidification and making it easy to clean the inner cavity 43.

[0046] When adding ink, it can be added from the inner tube shaft 528. When the inner tube shaft 528 is not squeezed with the inner blocking shaft 524, the inner blocking shaft 524 will block the outlet hole 525, so that the interior of the inner cavity 43 is in a relatively sealed state. When the inner tube shaft 528 and the inner blocking shaft 524 are squeezed, the outlet hole 525 and the inlet hole 529 are connected, and ink can be added to the inner cavity 43. In addition, the ink moving outward from the outlet hole 525 will enter into the hose 527. Through the hose 527, the newly added ink moves toward the lower end of the frame 51, directly and fully mixed with the old ink, and the ink can be further mixed through the through hole 511.

[0047] In addition, due to the action of the frame 51 and the through hole 511, the frame 51 separates the inner cavity 43 into two parts, and when the frame 51 reciprocates, the ink can only pass through the through hole 511 to achieve the jet effect, that is, a high-speed jet is formed when the ink is ejected from the through hole 511, which helps to further mix the ink. The up and down movement of the frame 51 may also produce a certain pumping effect, that is, when the frame 51 moves upward, the water below the through hole 511 is sucked into the through hole 511; when the frame 51 moves downward, the water above the through hole 511 is squeezed out of the through hole 511. This pumping effect also helps to mix and stir the ink.
