[0032] Example 1

[0033] like Figure 1-Figure 4 As shown, an embodiment of the present invention provides a multi-ink path synchronization control mechanism, characterized in that the mechanism includes:

[0034] A first supporting unit 2;

[0035] A second supporting unit 1, wherein the first supporting unit 2 and the second supporting unit 1 are installed relatively and parallel to each other, and a plurality of ink tubes 4 are installed between the first supporting unit 2 and the second supporting unit 1;

[0036] A driving unit 3 connected to the first supporting unit and / or the second supporting unit, wherein the driving unit 3 is used to drive the first supporting unit 2 and the second supporting unit 1 to move relative to each other, so as to open or close the passage in the ink tube 4 .

[0037] like Figure 1-3 As shown, the first support unit 2 and the second support unit 1 are long strip structures.

[0038] Specifically, there are multiple ink tubes 4 in the inkjet device, and the first support unit 2 and the second support unit 1 are set as a long strip structure. The ink path control of the multiple ink tubes 4 can be achieved through a first support unit 2 and a second support unit 1. While simplifying the installation, the ink tubes 4 in the inkjet device can also be made orderly, which is convenient for observation and maintenance.

[0039] In this embodiment, the opening and closing of the ink paths in the plurality of ink tubes 4 are controlled by setting the first support unit 2, the second support unit 1 and the driving unit 3. The plurality of ink tubes 4 are set between the first support unit 2 and the second support unit 1. The gap distance between the first support unit 2 and the second support unit 1 is driven and adjusted by the driving unit 3. When it is necessary to close the ink paths of the ink tubes 4, the driving member drives to shorten the distance between the first support unit 2 and the second support unit 1, so that the first support unit 2 and the second support unit 1 tighten the plurality of ink tubes 4 and close the ink paths of the ink tubes 4; when it is necessary to open the ink paths of the ink tubes 4, the driving member drives to loosen the ink tubes 4 from the first support unit 2 and the second support unit 1.

[0040] In one embodiment, if Figure 4 As shown, the multi-ink path synchronous control mechanism includes: the second support unit 1 is provided with a plurality of sliding holes 11, and a plurality of extrusion units 6 are respectively installed in the sliding holes on the second support unit 1, and the extrusion units 6 are used to squeeze the ink tube 4 to open or close the passage in the ink tube 4.

[0041] Specifically, a plurality of extrusion units 6 are arranged on the second support unit 1. When installed, each extrusion unit 6 is aligned with an ink tube 4, that is, the ink tube 4 is installed between the extrusion unit 6 and the first support unit 2, and the opening or closing of the ink paths of the plurality of ink tubes 4 is controlled by the extrusion unit 6 and the first support unit 2.

[0042] In one embodiment, if Figure 3 As shown, the first supporting unit 2 and the second supporting unit 1 are regular long strip structures, and the ink tube 4 is tightened by the side surface of the first supporting unit 2 and the side surface of the second supporting unit 1 .

[0043] In one embodiment, if Figure 4 As shown, a plurality of limiting grooves 21 are provided on the first supporting unit 2 , the ink tubes 4 are installed in the limiting grooves 21 , and the extrusion unit 6 is positioned in coordination with the limiting grooves 21 .

[0044] Specifically, by arranging a plurality of squeezing units 6 on the second supporting unit 1 and arranging a plurality of limiting grooves 21 on the first supporting unit 2, the ink tubes 4 pass through the limiting grooves 21 in the vertical direction, and the positions of the ink tubes 4 are fixed to a certain extent, so as to prevent the ink tubes 4 from being displaced, and the ink tubes 4 in the inkjet device are in order. At the same time, by arranging the squeezing units 6 and the limiting grooves 21 in a one-to-one correspondence, the squeezing units 6 and the limiting grooves 21 are matched in position, so that the squeezing units 6 can accurately squeeze the ink tubes 4 in the limiting grooves 21.

[0045] In another embodiment, if Figure 1-7 As described above, the first support unit 2 is a regular long strip structure, and a plurality of extrusion units 6 are disposed on the second support unit 1 , and a plurality of ink tubes 4 are clamped by the plurality of extrusion units 6 and the side wall of the first support unit 2 .

[0046] In one embodiment, if Figure 5 , Figure 6 As shown, the extrusion unit 6 includes an extrusion head 61 and an elastic member 62 , and the elastic member 62 is installed between the extrusion head 61 and the bottom of the sliding hole 11 .

[0047] Specifically, the elastic 62 is installed between the extrusion head 61 and the sliding hole 11, so that the extrusion head 61 can slide elastically in the sliding hole, and the extrusion head can elastically squeeze the ink tube 4, thereby avoiding damage to the ink tube 4 due to excessive squeezing force during squeezing.

[0048] In one embodiment, if Figure 6 As shown, the extrusion unit 6 further includes a limiting member 63, the extrusion head 61 is provided with a countersunk hole 64, and the limiting member is connected to the bottom of the sliding hole through the countersunk hole to limit the sliding of the extrusion head in the sliding hole.

[0049] Specifically, the limiting member 63 is connected to the bottom of the sliding hole 11 through the countersunk hole 64 , thereby limiting the sliding stroke of the extrusion head in the sliding hole, preventing the extrusion head from sliding out of the sliding hole and affecting the extrusion effect of the extrusion head on the ink tube 4 .

[0050] The bottom of the limiting member 63 away from the sliding hole 11 is relatively thick to prevent the limiting member 63 from sliding out of the countersunk hole 64 .

[0051] Preferably, the limit member 63 can slide inside the countersunk hole 64. When the extrusion unit 6 does not extrude the ink tube 4, the elastic member 62 acts on the extrusion head so that the limit member 63 is located at the bottom of the countersunk hole 64 and contacts the end of the extrusion head close to the bottom of the sliding hole 11. When the extrusion unit 6 extrude the ink tube 4, the extrusion head 63 is forced to slide toward the bottom of the sliding hole 11. Correspondingly, the limit member 63 slides in the countersunk hole 64 and moves relative to the extrusion head until the thick end of the limit member 63 contacts the end of the extrusion head away from the bottom of the sliding hole 11. The limit member 63 limits the sliding of the extrusion head 61 to ensure that the extrusion head 61 extrude the ink tube 4.

[0052] In one embodiment, the mechanism further includes a guide member 5 , one end of which passes through the first support unit 2 and is connected to the second support unit 1 , so as to fix the relative positions of the first support unit 2 and the second support unit 1 .

[0053] Specifically, a guide member 5 is provided on the first support unit 2 and the second support unit 1, and one end of the guide member 5 is connected to the first support unit 2, and the other end is connected to the second support unit 1, and is used to fix the relative position of the first support unit 2 and the second support unit 1 to prevent the first support unit 2 and the second support unit 1 from moving left and right relative to each other, and to avoid affecting the closing of the ink path during extrusion.

[0054] At the same time, it also avoids displacement of the extrusion unit 6 on the second support unit 1 and the limiting groove 21 on the first support unit 2, resulting in misalignment between the extrusion unit 6 and the limiting groove 21, making it impossible to close the ink path of the ink tube 4, affecting the opening / closing effect of the ink path.

[0055] In one embodiment, if Figure 4 As shown, the driving unit 3 includes a movable member 32 and a driving member 31 . The movable member 32 passes through the first supporting unit 2 and is connected to the second supporting unit 1 . The driving member 31 is connected and installed with the movable member 32 to drive the movable member 32 to move.

[0056] Specifically, one end of the movable member 32 is connected to the first support unit 2, and the other end is connected to the second support unit 1. The end connected to the first support unit 2 is connected to the driving member. The driving member 31 drives the movable member 32 to adjust the relative distance between the first support unit 2 and the second support unit 1, thereby shortening or increasing the distance between the first support unit 2 and the second support unit 1.

[0057] In one embodiment, the driving unit 3 is preferably a cylinder, the movable part 32 is a piston rod, the cylinder is installed on one side of the first support unit 2, the flange surface of the cylinder is in contact with the side of the first support unit 2 away from the second support unit 1, and the piston rod 32 passes through the first support unit 2 and is connected to the second support unit 1.

[0058] In one embodiment, the multi-ink path synchronization control mechanism is provided with a plurality of the driving units 3 , and each of the driving units 3 controls a plurality of the ink tubes 4 .

[0059] Specifically, when there are multiple ink tubes 4 in the mechanism and there is a large span between the distribution of the ink tubes 4, multiple drive units 3 can be set up. Each drive unit 3 can independently control multiple ink tubes 4 according to inkjet requirements to achieve the flow speed of the ink and meet the different speed requirements of different ink tubes 4 in the printing device.

[0060] In large-scale inkjet printing equipment, in order to realize inkjet printing of large-format substrates, or to increase the speed of inkjet printing operations, multiple print heads are set for inkjet printing. It is necessary to install multiple groups of ink tubes 4 corresponding to the print heads in the printing equipment. In order to realize the control of the ink output of the nozzle, multiple drive units 3 are set to control different ink tubes 4 with different ink flow technologies.

[0061] When inkjet printing is performed on a printing task, the consumption speed of each color of ink in different printing tasks is different. In order to ensure the quality of the ink and make the flow speed of different color inks match the consumption speed of different color inks in inkjet printing, by setting multiple drive units 3, the ink tubes 4 that transport different colors are controlled, so that the consumption speed of different color inks can be matched with the flow of ink tubes 4.

[0062] For example, when the printing device uses four-color inks C, M, Y, and K for inkjet printing, the drive unit 3 of the ink tube 4 setting unit corresponding to C, M, Y, and K is controlled. When the consumption of M color ink among the four-color inks C, M, Y, and K is large, the drive unit 3 can adjust the ink flow rate in the M color ink tube 4 so that the ink flow rate in the M color ink tube 4 matches the consumption rate of the M color ink, thereby avoiding affecting the printing speed or the ink being affected due to long-term non-use when the ink flows to the next position through the ink tube 4, thereby affecting the printing quality.

[0063] In one embodiment, the multi-ink-path synchronous control mechanism includes a connecting member, and the second supporting unit 1 is mounted on the connecting member to fix the multi-ink-path synchronous control mechanism in the inkjet device.

[0064] Specifically, the second supporting unit 1 is fixed to the connecting member by bolts.

[0065] In this embodiment, the multi-ink path synchronization control mechanism is fixedly installed in the inkjet device through a connecting piece, which plays a fixing role on the multi-ink path synchronization control mechanism.

[0066] The utility model controls the opening and closing of the ink paths in the plurality of ink tubes 4 by setting the first support unit 2, the second support unit 1 and the driving unit 3, and drives and adjusts the distance between the first support unit 2 and the second support unit 1 by the driving unit 3. When the ink paths of the ink tubes 4 need to be closed, the driving member drives to shorten the distance between the first support unit 2 and the second support unit 1, so that the first support unit 2 and the second support unit 1 tighten the plurality of ink tubes 4 and close the ink paths of the ink tubes 4; when the ink paths of the ink tubes 4 need to be opened, the driving member drives the first support unit 2 and the second support unit 1 to loosen the ink tubes 4. At the same time, the first support unit 2 is provided with a limiting groove 21, and the second support unit 1 is provided with an extrusion unit 6, and the plurality of ink tubes 4 are respectively embedded in the limiting groove 21, so as to realize the precise extrusion of the ink tubes 4 and the precise opening / closing of the ink paths of the ink tubes 4. The multi-ink path synchronous control mechanism provided by the utility model has a simple structure and is easy to control the opening / closing of the ink paths of the plurality of ink tubes 4. At the same time, the multi-ink path synchronous control mechanism provided by the utility model has a long service life and low cost.
