Description

Technical Field

[0001] The invention relates to the technical field of invisible inkjet coding, and in particular to an invisible inkjet coding device capable of meeting requirements of impregnated papers of different thicknesses. Background Art

[0002] Invisible inkjet printer is a special marking device that uses specific ink or material to print information on products or packaging that is not easily visible to the naked eye. This information usually requires a specific light source (such as ultraviolet light) or other detection methods to be visible. Invisible inkjet printer technology is widely used in anti-counterfeiting, tracking and security, and can help companies protect their brands, prevent counterfeiting, and achieve effective management and tracking of products.

[0003] Invisible inkjet printers usually need to spray special ink on the surface of impregnated paper, but different impregnated papers have different thicknesses, and the distance between the nozzle and the paper also needs to be adaptively adjusted. For example, when inkjetting on the surface of thinner impregnated paper, if the distance is too large, the code may not be clear or the ink distribution may be uneven; if the distance is too small, the paper may be damaged or the nozzle may be clogged. And thinner impregnated paper usually has a lower density and less resin content, which means that the invisible ink may penetrate into the paper faster, especially when using highly permeable ink, which may cause blurred handwriting or back-printing, affecting the clarity and concealment of the code.

[0004] When inkjet printing, the follower wheel (or guide wheel) at one end of the invisible inkjet printhead is usually pressed on the surface of the impregnated paper and rolled, which can not only keep a relatively stable distance between the printhead and the surface of the object, but also reduce the friction between the device and the impregnated paper during movement.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figure 1-Figure 8 , an invisible inkjet coding device that can meet the needs of impregnated papers of different thicknesses, including an inkjet printer body 1 and a handle 2 installed on the bottom surface of the inkjet printer body 1, a processing box 3 is fixedly connected to the front end of the inkjet printer body 1, a processing chamber 9 is opened on the side of the processing box 3 close to the inkjet printer body 1, and lifting ports 23 connected to the processing chamber 9 are opened at the four ends of the processing box 3, a coding port 16 connected to the nozzle of the inkjet printer body 1 is opened through the middle of the processing box 3, and a plurality of drying ports 20 are opened through the side of the processing chamber 9 away from the inkjet printer body 1, a power mechanism is connected to the side of the inkjet printer body 1 close to the processing box 3, the power mechanism is located in the processing chamber 9, the output end of the power mechanism is connected to a lifting component, the four ends of the lifting component respectively penetrate the four lifting ports 23, and the four ends of the lifting component located outside the processing box 3 are connected to rolling components, one end of the lifting component located in the processing chamber 9 is connected to the drying mechanism, the output end of the drying mechanism is matched and connected with the drying port 20, and the inner wall of the processing box 3 away from the drying port 20 is fixedly connected with a monitoring sensor 17.

[0025] like Figures 1 to 8 As shown, the invisible inkjet coding device of the present invention that can meet the requirements of impregnated papers of different thicknesses can be used in the following steps: 1. First, without starting the printer body 1 for coding, align the coding port 16 of the processing box 3 at the front end of the printer body 1 with the location to be coded. At this time, the monitoring sensor 17 arranged inside the front end of the processing box 3 will automatically determine the thickness of the impregnated paper to be coded, and then transmit the thickness to the internal processor of the printer body 1 through an electrical signal, and start the power mechanism through the internal controller of the printer body 1.

[0026] 2. After the power mechanism is started, the output shaft will lift the lifting component inside the processing chamber 9, and as the lifting component inside the processing chamber 9 is lifted, the part of the lifting component outside the processing box 3 will also be lifted together, and then the four rolling components can be moved outside the processing box 3, so that the height between the rolling component and the inkjet port 16 of the processing box 3 can be changed, so that more impregnated paper with different thicknesses can be adapted to inkjet.

[0027] 3. Some inks may dry slowly or may easily cause penetration, mixing, blurring, etc. due to the thin impregnated paper. When the handle 2 is used to push the printer body 1 to follow the rolling assembly to move the inkjet printer, the drying mechanism can be turned on at the same time. After the drying mechanism is started, hot air can be sprayed on the surface of the impregnated paper, thereby accelerating the drying of the ink and reducing the probability of penetration, mixing, blurring, etc.

[0028] Special mention should be made here: 1. The invisible inkjet printer that can meet the requirements of impregnated paper of different thicknesses in the present invention is similar in structure to the existing invisible inkjet printer, such as the model: Leo M90 handheld invisible inkjet printer.

[0029] 2. The monitoring sensor 17 mentioned above can be an ultrasonic thickness sensor, a capacitive thickness sensor or other sensor that can directly measure the thickness of the impregnated paper. Of course, other sensors with equivalent functions can also be used, and there is no specific limitation.

[0030] 3. Regardless of the existing writing method or human habit, the printer body 1 is controlled to move from left to right, so the drying mechanism is set on the left side of the inkjet port 16. After the inkjet printer body 1 sprays the ink from the inkjet port 16 onto the impregnated paper, it can be dried immediately by the drying mechanism, and the position of the drying mechanism has not exceeded the two rolling components located on the left side of the processing box 3. Therefore, after the ink is dried, even if the rolling component rolls to the surface of the ink, it will not affect the ink.

[0031] As a preferred solution of the present invention, the power mechanism includes a slide rod 10, a lifting motor 14 and a threaded rod 15. The outer wall of the lifting motor 14 and one end of the slide rod 10 are fixedly connected to the outer wall of the inkjet printer body 1 close to the processing box 3. The output shaft of the lifting motor 14 is fixedly connected to one end of the threaded rod 15. The other end of the threaded rod 15 penetrates the lifting assembly and is rotatably connected to the inner wall of the processing chamber 9. The threaded rod 15 and the slide rod 10 are arranged in parallel. The end of the slide rod 10 away from the inkjet printer body 1 penetrates the lifting assembly and is fixedly connected to the inner wall of the processing chamber 9.

[0032] More specifically, when it is necessary to control the lifting assembly to adjust the height, it is only necessary to turn on the switch of the lifting motor 14 through the internal controller of the inkjet printer body 1. The output shaft of the lifting motor 14 can rotate to drive the threaded rod 15 to rotate, and the threaded rod 15 cooperates with the sliding rod 10 to drive the lifting assembly to be lifted and lowered inside the processing chamber 9.

[0033] As a preferred solution of the present invention, the lifting assembly includes a slide plate 12 and four connecting plates 6, the side wall of the slide plate 12 is slidably connected to the inner wall of the processing chamber 9, the outer wall of the threaded rod 15 is threadedly connected to the inner wall of the slide plate 12, the outer wall of the slide rod 10 is slidably connected to the inner wall of the slide plate 12, the four ends of the slide plate 12 are respectively fixedly connected to one side of the four connecting plates 6, the other ends of the four connecting plates 6 respectively pass through the four lifting ports 23 and are respectively connected to the four rolling assemblies, the side walls of the four connecting plates 6 are respectively slidably connected to the inner walls of the four lifting ports 23, the upper surface of the slide plate 12 is penetrated by a sliding port 24, the drying mechanism is located in the sliding port 24, and the monitoring sensor 17 is located in the processing chamber 9 and is slidably connected to the slide plate 12 at one end.

[0034] More specifically, when the threaded rod 15 rotates, the threaded rod 15 will cooperate with the slide rod 10 to move the slide plate 12 along the inside of the processing chamber 9. As the slide plate 12 moves, it will move with the four connecting plates 6 located outside the processing box 3, thereby changing the height of the four rolling components connected by the four connecting plates 6 outside the processing box 3.

[0035] As a preferred embodiment of the present invention, the drying mechanism includes an air inlet pipe 11, a drying box 13, a heating wire 27 and a blowing assembly. A docking port 22 is provided on a side of the processing chamber 9 close to the drying port 20. The outer wall of the lower end of the drying box 13 is fixedly connected to the inner wall of the docking port 22. An air outlet 26 is provided on the bottom surface of the drying box 13. A drying chamber 25 is provided inside the drying box 13. The heating wire 27 is located in the drying chamber 25, and both ends of the heating wire 27 pass through the side wall of the drying box 13 and are fixedly connected to the penetration. One end of the air inlet pipe 11 is fixedly connected to one side of the upper end of the drying box 13. The blowing assembly is located in the air inlet pipe 11. The processing chamber 9, the air inlet pipe 11, the drying chamber 25, the air outlet 26, the docking port 22 and several drying ports 20 are internally connected.

[0036] More specifically, when it is necessary to dry the ink sprayed from the inkjet printer 16, it is only necessary to turn on the air outlet component, and the air blowing component will blow the air in the processing chamber 9 into the drying chamber 25 through the air inlet pipe 11. The air entering the drying chamber 25 will be heated by the heating wire 27, and then the heated air will continue to descend and spray onto the surface of the impregnated paper from the air outlet 26, the docking port 22 and several drying ports 20, thereby accelerating the drying of the ink on the surface of the impregnated paper.

[0037] It should be noted here that: the heating wire 27 is an existing mature technology, so its principle is not described in detail; both ends of the heating wire 27 are electrically connected to the inside of the inkjet printer body 1.

[0038] As a preferred solution of the present invention, the blowing assembly includes a cross bracket 28, a blowing motor 29 and fan blades 30. The four ends of the cross bracket 28 are fixedly connected to the inner wall of the air inlet pipe 11 at one end away from the drying box 13. The outer wall of the blowing motor 29 is fixedly connected to the middle part of the cross bracket 28 close to the drying box 13. The output shaft of the blowing motor 29 is fixedly connected to the central axis of the fan blades 30.

[0039] More specifically, when it is necessary to blow the air inside the dust reduction treatment chamber 9 into the drying chamber 25, it is only necessary to turn on the blowing motor 29 installed on the cross bracket 28. The output shaft of the blowing motor 29 can drive the fan blades 30 to rotate, and after the fan blades 30 rotate, the air inside the treatment chamber 9 can be blown into the drying chamber 25.

[0040] As a preferred embodiment of the present invention, the rolling assembly includes a follower wheel 5, a support block 8 and a support shaft 18, one end of the support block 8 is fixedly connected to the bottom surface of the connecting plate 6 at one end outside the processing box 3, the other end of the support block 8 is sleeved and rotatably connected to the outer wall of one end of the support shaft 18, and the other end of the support shaft 18 passes through the inner wall of the follower wheel 5 and is fixedly connected to the inner wall of the follower wheel 5.

[0041] More specifically, when the connecting plate 6 is raised and lowered on the following slide plate 12, the following wheel 5, the support block 8 and the support shaft 18 will move together, so that the height between the surface of the following wheel 5 and the impregnated paper can be changed. After the height is adjusted, the surface of the following wheel 5 only needs to be placed on the surface of the impregnated paper, and the following wheel 5 and the support shaft 18 can be connected with the support block 8 by rotation, so that the inkjet printer body 1 can be controlled to move stably on the surface of the impregnated paper.

[0042] As a preferred solution of the present invention, elastic cloths 7 are fixedly connected to both sides of the connecting plate 6 , and the other ends of the two elastic cloths 7 are fixedly connected to both sides of the lifting opening 23 .

[0043] More specifically, by providing the elastic cloth 7, firstly, the lifting port 23 can be shielded to reduce the probability of larger external debris entering the processing chamber 9; secondly, the lifting port 23 can be shielded from the appearance, making it look relatively beautiful.

[0044] As a preferred solution of the present invention, a shielding soft cloth 4 is hinged on one side of the processing box 3 close to the handle 2, a magnet 21 is fixedly connected to the other end of the shielding soft cloth 4 close to the processing box 3, another magnet 21 is fixedly connected to the side of the processing box 3 away from the handle 2, and the shielding soft cloth 4 and the two magnets 21 on the processing box 3 match and attract each other. A sealing plug 19 is fixedly connected to the side of the shielding soft cloth 4 close to the processing box 3, and the outer wall of the sealing plug 19 is slidably connected to the inner wall of the inkjet printer port 16.

[0045] More specifically, when the inkjet printer body 1 is not needed for inkjet printing, the inkjet printing port 16, drying port 20 and monitoring sensor 17 at the front end of the processing box 3 can be shielded by the provided shielding soft cloth 4 to reduce the probability of contamination, blockage and damage.

[0046] By providing magnets 21 on both the processing box 3 and the shielding soft cloth 4, the connection stability between the shielding soft cloth 4 and the processing box 3 can be increased to prevent the shielding soft cloth 4 from being easily loosened and falling off.

[0047] By setting the sealing plug 19, firstly, the shielding soft cloth 4 can be inserted into the inkjet printing port 16 during the period of shielding the inkjet printing port 16, thereby further increasing the protection of the inkjet printing port 16; secondly, the sealing plug 19 can also increase the connectivity between the shielding soft cloth 4 and the middle part of the processing box 3, thereby avoiding the shielding soft cloth 4 and the middle part of the processing box 3 from warping up.

[0048] Special mention should be made here: 1. The shielding soft cloth 4 and the sealing plug 19 are both made of silicone, rubber or other deformable and wear-resistant materials, and are not specifically limited.

[0049] 2. The hinged connection between the shielding soft cloth 4 and the processing box 3 means that the shielding soft cloth 4 itself is made of a deformable and bendable material, and the shielding soft cloth 4 is directly connected to the processing box 3 and can be hinged and unfolded relatively, rather than being hinged by hinges or hinges.

[0050] 3. The shielding soft cloth 4 is hinged to one end of the processing box 3 close to the handle 2. When the inkjet printer body 1 is used for inkjet coding, the shielding soft cloth 4 can be bent and folded to the handle 2. The user can hold the shielding soft cloth 4 while holding the handle 2. It is not only convenient to hold, but the shielding soft cloth 4 will not block the inkjet coding line of sight and the inkjet coding process.
