Description

Technical Field

[0001] This invention relates to the field of printing technology, and more specifically, to a VOC gas collection printing device based on ink organic solution. Background Technology

[0002] VOC is an abbreviation for volatile organic compounds. In a general sense, VOC refers to volatile organic compounds; however, in an environmental context, it refers to a more reactive type of volatile organic compound, namely, the kind that can cause harm.

[0003] In existing technologies, inks used in ink printing contain VOC gases. If these gases are not treated in a timely manner during ink use, they will be released into the workshop, affecting the air quality and the health of the workers. Furthermore, during ink use, the rotation of the rollers will splash ink from the ink tank, contaminating the printing press and the workshop floor, making cleaning difficult. Summary of the Invention

[0004] This invention proposes a VOC gas collection printing device based on the organic solution of ink, which solves the problem that in the prior art, the ink used in ink printing contains VOC gas. If the VOC gas is not treated in time during the use of ink, it will be emitted into the workshop, affecting the air quality of the workshop and the health of the workshop workers. In addition, during the use of ink, the rotation of the roller will splash ink in the ink tank, contaminating the printing machine and the workshop floor, which is inconvenient to clean.

[0019] As a further technical solution, the edge of the collection cover has a notch that matches the ink delivery pipe.

[0020] As a further technical solution, a baffle is also included, which is rotatably mounted on the inner bottom of the collection cover via a torsion spring shaft.

[0021] As a further technical solution, the collection cover is semi-cylindrical.

[0023] As a further technical solution, an ink cleaning mechanism is also included, the ink cleaning mechanism comprising,

[0024] The machine base plate is mounted on the working surface.

[0025] The machine includes two lifting drive components, both of which are mounted on the machine base plate.

[0026] Mounting plate, which is mounted on top of the two lifting drive components.

[0027] Two telescopic drive components are provided and mounted on the mounting plate.

[0028] The second connecting frame is installed at the telescopic ends of the two telescopic drive components.

[0029] The rotating shaft has both ends mounted on the second connecting frame via electric rotating shaft seats.

[0030] The nozzles are provided in multiple units, and the multiple nozzles are mounted on the second connecting frame.

[0031] The device includes two electrically operated telescopic plates, each mounted on one side of the outer surface of the rotating shaft.

[0032] Side bristles: Each telescopic section of the electric telescopic plate has densely packed side bristles on the side away from the centerline of the second connecting frame.

[0033] A brush roller is rotatably mounted between the telescopic ends of the two electric telescopic plates.

[0034] As a further technical solution, a control component is also included, the control component comprising:

[0035] There are two first pull ropes, each connected to the upper outer side of the baffle. The first pull ropes are embedded in grooves on the baffle.

[0036] The first T-shaped block is attached to the bottom of each of the first pull ropes.

[0037] There are two second pull ropes, which are slidably disposed in the holes of the collection cover.

[0043] The working principle and beneficial effects of this invention are as follows:

[0044] In this invention, when using the VOC gas collection printing device based on ink organic solution, sufficient ink is first added, and the product to be printed is wound onto the conveyor roller assembly. Then, printing is started. The translation component moves the collection hood closer to the printing press, covering the ink tank and the inking roller. This is because the ink tank and the inking roller are the areas most prone to emitting VOC gas during printing, as these areas contain a large amount of ink material. Therefore, they need to be covered. During printing, as the inking roller rotates continuously, its lower part rotates in the ink tank, splashing ink out. This splashed ink is intercepted on the inner surface of the collection hood, and the emitted VOC gas also enters the collection hood. The storage component collects and processes the VOC gas entering the collection hood, preventing VOC gas from escaping into the workshop and affecting the air quality, while also preventing ink splashing.

[0059] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0060] Example 1

[0061] like Figures 1-5 As shown, this embodiment proposes a VOC gas collection printing device based on ink organic solution, including a printing machine 1, which is mounted on a working plane.

[0062] It also includes a gas collection mechanism, which includes,

[0063] The translation components are provided in two symmetrical configurations, and the two translation components are mounted on a working plane.

[0064] The collection cover 7 is installed between the moving ends of the two translation components. In the printing state, the collection cover 7 covers the outside of the ink tank 2 and the inking roller 3 on the frame of the printing press 1.

[0065] A storage component is mounted on a working plane and is connected to the collection cover 7.

[0066] In this embodiment, when using the VOC gas collection printing device based on ink organic solution, sufficient ink is first added, and the product to be printed is wound onto the conveyor roller group. Then, printing is started. The translation component will drive the collection cover 7 to move closer to the printing machine 1, covering the ink tank 2 and the inking roller 3. Because the ink tank 2 and the inking roller 3 are the most likely places to emit VOC gas during the printing process, and these locations contain a large amount of ink raw materials, it is necessary to cover them. During the printing process, as the inking roller 3 rotates continuously, the lower part of the inking roller 3 will rotate in the ink tank 2, splashing the ink inside the ink tank 2. At this time, the splashed ink will be intercepted on the inner surface of the collection cover 7. At the same time, the emitted VOC gas will also enter the collection cover 7, and the VOC gas entering the collection cover 7 will be collected and processed by the storage component, preventing the VOC gas from escaping into the workshop and affecting the air quality of the workshop, and also preventing ink splashing.

[0067] The translation component includes,

[0068] Electric slide rail 4, which is mounted on the working surface.

[0069] The electric slide block 5 is slidably disposed within the electric slide rail 4.

[0070] The first connecting frame 6 is mounted on the electric slide 5, and the collection cover 7 is mounted between the two first connecting frames 6 in the two translation components.

[0071] In this embodiment, the electric slide block 5 slides in the electric slide rail 4, and the collection cover 7 is moved horizontally by the first connecting frame 6.

[0072] The storage component includes,

[0073] The first mounting bracket 11 is mounted on the working surface.

[0074] A collection pipe 8 is provided, with its first end connected to the collection cover 7 and its second end connected to a vacuum pump 9, which is mounted on the first mounting bracket 11.

[0075] Gas collection chamber 10 is mounted on the first mounting bracket 11 and is connected to the outlet of the air pump 9.

[0076] In this embodiment, the emitted VOC gas enters the collection hood 7, and at the same time, the vacuum pump 9 extracts the gas, and the VOC gas in the collection hood 7 is extracted through the collection pipe 8 and discharged into the gas collection chamber 10, where the gas collection chamber 10 temporarily stores and processes the VOC gas.

[0077] The edge of the collection cover 7 has a notch that matches the ink delivery pipe.

[0078] Example 2

[0079] like Figures 1-12 As shown, based on Embodiment 1, a baffle 12 is also included, which is rotatably mounted on the inner bottom of the collection cover 7 via a torsion spring shaft.

[0080] The collection cover 7 is semi-cylindrical.

[0081] An interceptor plate 13 is provided on the inner side of the notch connecting the collection cover 7 and the collection pipe 8. The upper end of the interceptor plate 13 is rotatably mounted on the upper edge of the inner notch of the collection cover 7 via a torsion spring shaft.

[0082] In this embodiment, since ink will splash out, the splashed ink is intercepted by the interceptor plate 13. In the working state, the interceptor plate 13 is tilted downwards, and the gas can be drawn out from the opening on the lower side. At the same time, the ink can be prevented from splashing into the gas collection pipe 8. After the ink splashes onto the inner wall of the collection cover 7, the excess ink will flow down along the inner wall of the collection cover 7. In order to prevent the ink from dripping down, the baffle 12 will intercept it at the lower edge of the collection cover 7, ensuring that the ink is intercepted inside the baffle 12 and preventing the ink from dripping down.

[0083] It also includes an ink cleaning mechanism, which includes,

[0084] Machine base plate 23, which is mounted on the working surface.

[0085] There are two lifting drive components 24, which are mounted on the machine base plate 23.

[0086] Mounting plate 25, which is mounted on top of the two lifting drive components 24.

[0087] There are two telescopic drive components 26, which are mounted on the mounting plate 25.

[0088] The second connecting frame 27 is mounted on the telescopic ends of the two telescopic drive members 26.

[0089] The rotating shaft 28 has both ends mounted on the second connecting frame 27 via electric rotating shaft seats.

[0090] A plurality of nozzles 29 are provided, and the plurality of nozzles 29 are mounted on the second connecting frame 27.

[0091] Two electrically operated telescopic plates 30 are provided, and the two electrically operated telescopic plates 30 are respectively installed on both sides of the outer surface of the rotating shaft 28.

[0092] Side bristles 31: Each telescopic section of the electric telescopic plate 30 has densely packed side bristles 31 on the side away from the centerline of the second connecting frame 27.

[0093] The brush roller 32 is rotatably mounted between the telescopic ends of the two electric telescopic plates 30.

[0094] In this embodiment, when the printing press 1 stops working, the electric slide 5 is controlled to reverse and reset, causing the collection cover 7 to move away from the printing press 1. After resetting, the two lifting drive components 24 rise upwards, and then the lifting drive components 24 drive the mounting plate 25 to move upwards. The mounting plate 25 drives the telescopic drive component 26, the second connecting frame 27, the rotating shaft 28, the nozzle 29, the electric telescopic plate 30, the side brush bristles 31, and the brush roller 32 to move upwards until the brush roller 32 is directly opposite the collection cover 7. Then the telescopic drive component 26 extends, driving the brush roller 32 to move to the inside of the collection cover 7, so that the brush roller... The nozzle 22 contacts the inner wall of the collection hood 7 and connects the water inlet of the nozzle 29 to the external ink cleaning agent delivery pipe. The ink cleaning agent is sprayed onto the inner wall of the collection hood 7 through the nozzle 29. Then, the rotating shaft 28 rotates, driving the electric telescopic plate 30 and the brush roller 32 to rotate. The electric telescopic plate 30 extends and retracts in real time to ensure that the brush roller 32 rotates in close contact with the inner wall of the collection hood 7, brushing and cleaning the ink on the inner wall, avoiding ink residue on the inner wall of the collection hood 7 for a long time and making it impossible to remove. At the same time, the side brush bristles 31 on the electric telescopic plate 30 will clean the other two side walls of the collection hood 7, realizing automatic cleaning of the collection hood 7.

[0095] It also includes a control component, which includes,

[0096] Two first pull ropes 14 are provided, each connected to the upper outer side of the baffle 12, and each first pull rope 14 is embedded in a groove on the baffle 12.

[0097] A first T-shaped block 15 is connected to the bottom of each of the first pull ropes 14.

[0098] There are two second pull ropes 16, which are slidably disposed in the holes of the collection cover 7. The first ends of the two second pull ropes 16 are respectively connected to the two sides of the interception plate 13. The second end of each second pull rope 16 is connected to a third pull rope 17, and the bottom end of each third pull rope 17 is connected to a second T-shaped block 18.

[0099] Connecting plate 19, which is mounted on the first mounting bracket 11.

[0100] The second mounting bracket 20 is fixedly connected to the connecting plate 19.

[0101] Extension rods 21, four of which are provided and mounted on the second mounting bracket 20.

[0102] Positioning fork 22, each of the extension rods 21 is fixed to one end away from the second mounting bracket 20.

[0103] The positioning fork 22 is U-shaped, and the tips of the two forks of the positioning fork 22 are in an outward-expanding state.

[0104] In this embodiment, during the resetting movement of the collection cover 7, the two first pull ropes 14 and the two third pull ropes 17 will enter between the four positioning forks 22. The first T-shaped block 15 and the second T-shaped block 18 are located below the positioning forks 22. After moving to the end of the positioning fork 22, the movement continues. The first T-shaped block 15 and the second T-shaped block 18 will be stuck on the lower side of the positioning fork 22. At this time, the collection cover 7 continues to move. The first T-shaped block 15 pulls the baffle 12 downward through the first pull rope 14, so that the baffle 12 opens downward. At the same time, the second T-shaped block 18 and the third pull rope 17 pull the intercepting plate 13 through the second pull rope 16, so that the intercepting plate 13 rotates and fits against the inner wall of the collection cover 7. Therefore, when the brush roller 32 cleans the inner wall of the collection cover 7, it will not be affected by the baffle 12 and the intercepting plate 13.

[0105] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
