Description

Technical Field

[0001] The utility model belongs to the technical field of printing, and particularly relates to a mist suction system and an inkjet printing device. Background Art

[0002] Inkjet printing technology is a type of digital printing that forms images or texts by controlling the ejection of tiny ink droplets onto a medium (such as paper, fabric, or other surfaces). However, during the inkjet printing process, especially during high-speed printing or when using special inks (such as highly volatile inks), not all ink droplets can accurately land on the printing medium. Some ink droplets will break down into extremely small ink particles in the air, forming what is called "ink mist". These tiny ink particles may drift into the interior or exterior environment of the printer, leading to problems such as reduced print quality and environmental pollution.

[0003] Although there are already related technologies to deal with such problems, there are still certain defects in these technologies. For example, Chinese Patent CN117734315A discloses a nozzle bottom plate structure with air suction holes, which includes a bottom plate and several printing nozzles. An installation groove is opened on the bottom surface of the bottom plate, and several printing nozzles are evenly installed in the installation groove in a linear arrangement. Several air suction holes are opened on the bottom surface of the bottom plate, and several air suction holes are evenly arranged in a linear arrangement on one side of the installation groove. Although this technical solution can absorb the ink gas generated by the nozzles during the ink spraying process, there is still a problem that the adsorption area cannot be controlled. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model proposes a mist suction system that can control the air suction volume entering the adsorption main body from the negative pressure air suction device, thereby controlling the adsorption area.

[0005] The technical solution of the utility model is realized as follows:

[0006] The first aspect of the utility model provides a mist suction system for adsorbing ink mist during the printing process. The mist suction system includes an adsorption main body and a negative pressure air suction device. A first air suction pipe is provided inside the adsorption main body, and several air suction holes are provided below the adsorption main body. The upper parts of the air suction holes are all communicated with the first air suction pipe. A plurality of air suction pipe interfaces connecting the first air suction pipe and the negative pressure air suction device are distributed on the first air suction pipe. The air suction pipe interfaces are connected with several adjusting devices for adjusting the opening and closing of the pipe. Several detachable partitions are provided in the first air suction pipe, and in the inserted state, the partitions divide the first air suction pipe into at least two isolated pipes.

[0007] Different from the prior art, a fog absorption system provided by the present utility model can control the opening or closing of the air suction holes below the isolation pipeline, and thus control the air suction volume of the negative pressure air suction device entering the adsorption main body, and further control the adsorption width by setting a detachable partition board and an adjusting device and controlling the switch or closing of the adjusting device.

[0008] It should be noted that the closing of the air suction holes in the present utility model means that when the adjusting device is switched, the negative pressure air suction cannot enter the air suction holes, and the black fog cannot be taken away naturally.

[0009] It should be noted that the adsorption width in the present utility model refers to the amount of ink fog that needs to be absorbed in a certain width range.

[0010] Preferably, the number of detachable partition boards is N, where N is an even number, such as 2, 4, 6, 8, etc. The N partition boards are distributed in the first air suction pipeline symmetrically with the center line of the first air suction pipeline as the axis of symmetry.

[0011] By setting like this, the isolation pipelines on both sides of the center line are symmetrically arranged, which can better control the air suction width.

[0012] Preferably, the N partition boards divide the first air suction pipeline into N + 1 isolation pipelines, and each isolation pipeline is provided with at least one air suction pipeline interface.

[0013] Preferably, the number of adjusting devices for adjusting the opening and closing of the pipeline is equal to or less than the number of isolation pipelines.

[0014] Preferably, the negative pressure air suction device includes an air suction channel, and the air suction channel is connected to the air suction pipeline interface.

[0015] Preferably, the fog absorption system further includes an automatic control component, and the automatic control component is connected to the adjusting device.

[0016] By setting like this, the automatic control component can automatically control the switch or closing of the adjusting device.

[0017] Preferably, the negative pressure air suction device is a high-pressure vortex blower.

[0018] The second aspect of the present utility model provides an inkjet printing device, which includes a nozzle installation bottom plate and the above-mentioned fog absorption system. The fog absorption system is arranged on the nozzle installation bottom plate. There are two fixed hole positions on one side of the nozzle installation bottom plate. The fog absorption system further includes two installation and fixing holes arranged at both ends of the adsorption main body. The installation and fixing holes are fixed to the fixed hole positions through fixing bolts.

[0019] By setting like this, the fog absorption system can be installed on the nozzle installation bottom plate.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] (1) A fog absorption system provided by the utility model, by setting a partition board and an adjusting device, by controlling the opening or closing of the adjusting device, the opening or closing of the air suction holes below the isolation pipeline can be controlled, so that the air suction volume of the negative pressure air suction device entering the adsorption main body can be controlled, and thus the adsorption width can be controlled.

[0022] (2) An inkjet printing device provided by the utility model, by installing a fog absorption system, during the inkjet printing process, especially during high-speed printing or when using special inks (such as highly volatile inks), by setting the fog absorption system, the fine ink particles generated during the printing process can be efficiently absorbed and filtered, and the air suction width can be adjusted to achieve the best effect of adsorbing ink mist width.

[0037] Embodiment 1

[0038] See Figures 1 to 6, this embodiment discloses a mist suction system for adsorbing ink mist during the printing process, which includes an adsorption main body 1 and a negative pressure air suction device 2. A first air suction pipe 13 is arranged inside the adsorption main body 1, and several air suction holes 12 are arranged below the adsorption main body 13. The upper parts of the air suction holes 12 are all communicated with the first air suction pipe 13. A plurality of air suction pipe interfaces 131 connecting the first air suction pipe 13 and the negative pressure air suction device 2 are distributed on the first air suction pipe 13. The air suction pipe interfaces 131 are connected with several regulating devices 31 for regulating the opening and closing of the pipeline. A plurality of detachable partitions 14 are arranged inside the first air suction pipe 13. In the inserted state, the partitions 14 divide the first air suction pipe 13 into at least two isolated pipelines.

[0039] In the mist suction system provided by this embodiment, by arranging a plurality of detachable partitions 14 and regulating devices 31, by controlling the opening or closing of the regulating devices 31, the opening or closing of the air suction holes 12 below the isolated pipeline provided with the regulating device 31 can be controlled, so that the air suction volume of the negative pressure air suction device 2 entering the adsorption main body 1 can be controlled, and thus the adsorption width can be controlled.

[0040] Specifically, the plurality of detachable partitions 14 are N in number, where N is an even number, which can be two, four, six, eight, etc. The N partitions divide the first air suction pipe into N + 1 isolated pipelines. Each of the isolated pipelines is provided with at least one air suction pipe interface. In this embodiment, taking four partitions 14 as an example, the four partitions 14 are distributed in the first air suction pipe 13 symmetrically with the center line of the first air suction pipe 13 as the axis of symmetry, and the first air suction pipe 13 is sequentially divided into a first isolated pipeline 1321, a second isolated pipeline 1322, a third isolated pipeline 1323, a fourth isolated pipeline 1324, and a fifth isolated pipeline 1325 from left to right. Each of the isolated pipelines is provided with at least one air suction pipe interface 131. Among them, the first isolated pipeline 1321, the second isolated pipeline 1322, the fourth isolated pipeline 1324, and the fifth isolated pipeline 1325 are each provided with one air suction pipe interface 131, and the third isolated pipeline 1323 is provided with three air suction pipe interfaces 131.

[0041] Specifically, the number of adjusting devices 31 for adjusting the opening and closing of the pipelines is equal to or less than the number of isolation pipelines. In this embodiment, there are four adjusting devices 31, including a first adjusting device 311, a second adjusting device 312, a third adjusting device 313, and a fourth adjusting device 314. The air suction pipeline interface 131 of the first isolation pipeline 1321 is connected to the first adjusting device 311, the air suction pipeline interface 131 of the second isolation pipeline 1322 is connected to the second adjusting device 312, the air suction pipeline interface 131 of the fourth isolation pipeline 1324 is connected to the third adjusting device 313, and the air suction pipeline interface 131 of the fifth isolation pipeline 1325 is connected to the fourth adjusting device 314. Three air suction holes 12 are provided below the first isolation pipeline 1321, the second isolation pipeline 1322, the fourth isolation pipeline 1324, and the fifth isolation pipeline 1325. Thus, when the switches of the first adjusting device 311, the second adjusting device 312, the third adjusting device 313, and the fourth adjusting device 314 are turned on or off, the opening and closing of the air suction holes 12 below the first, second, third, and fourth isolation pipelines can be controlled respectively, thereby adjusting the size of the adsorption area.

[0042] Specifically, the negative pressure air suction device 2 includes a first air suction channel 21 and a plurality of second air suction channels 21 communicating with the first air suction channel. An adjusting device 31 may or may not be provided between the second air suction channel 21 and the air suction pipeline interface 131. After the negative pressure air suction device 2 operates to generate air suction negative pressure, the negative pressure can reach each air suction pipeline interface 131 of the opened adjusting device through the plurality of air suction channels 21, then reach the isolation pipeline through the air suction pipeline interface 131, and then after the air suction negative pressure enters the air suction hole 12, the ink mist generated during the printing process can be taken away.

[0043] When the system of this embodiment operates, when the first adjusting device 311, the second adjusting device 312, the third adjusting device 313, and the fourth adjusting device 314 are all closed ( Figure 4 as long as the green part is filled with negative pressure), the area for sucking ink mist is 1200 mm.

[0044] When the first adjusting device 311 and the fourth adjusting device 314 are closed ( Figure 4 as long as the green and blue parts are filled with negative pressure), the area for sucking ink mist is 1500 mm.

[0045] When the first adjusting device 311, the second adjusting device 312, the third adjusting device 313, and the fourth adjusting device 314 are all opened ( Figure 4 as long as the green part, the blue part, and the red part are all filled with negative pressure), the area for sucking ink mist is 1800 mm.

[0046] Preferably, the fog absorption system may further include an automatic control component, which is connected to the adjusting device 31. The automatic control component can automatically control the switch and closure of the adjusting device 31, thereby automatically controlling the adsorption width. In this embodiment, the automatic control component is a UI interface, and the adjusting device is an electronic adjusting device.

[0047] During operation, after the operator inputs the fabric width on the device UI interface, the UI interface can automatically control the switch and closure of the first adjusting device 311, the second adjusting device 312, the third adjusting device 313, and the fourth adjusting device 314 according to the fabric width.

[0048] The specific control method is as follows: when the fabric width is greater than or equal to 1.5 meters, the first adjusting device 311, the second adjusting device 312, the third adjusting device 313, and the fourth adjusting device 314 are all set to the open state;

[0049] when the fabric width is greater than 1.2 meters and less than 1.5 meters, the second adjusting device 312 and the third adjusting device 313 are set to the open state;

[0050] when the fabric width is less than or equal to 1.2 meters, the first adjusting device 311, the second adjusting device 312, the third adjusting device 313, and the fourth adjusting device 314 are all set to the closed state.
