Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a printing equipment with an online coding function. Background Art

[0002] Inline inkjet printers are devices used to mark and encode products on production lines and are widely used in industries such as food, pharmaceuticals, cosmetics, and electronics. These devices can print information such as production date, batch number, barcode, and QR code in real time, ensuring product traceability and regulatory compliance.

[0003] In the existing technology, since both printing and coding are done by brushing pigments onto the packaging, this mixed pigment brushing method will result in the visibility of the coding information being affected when the coding overlaps with the dark areas of the printed pattern, thereby affecting the subsequent traceability and compliance of the packaging. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a printing device with an online inkjet coding function, so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A printing device with an online inkjet coding function includes a base, a material discharging unit, a printing unit, a drying unit, and a material receiving unit are arranged on the top of the base from right to left in sequence, a coding unit is arranged between the printing unit and the drying unit, and the coding unit includes a housing, a coding device, an electric heating component, a linear component, and a photoreceptor. The electric heating component is arranged on the side of the housing close to the printing unit, and a coding slot is horizontally opened above the electric heating component in the housing;

[0007] There are two linear components, which are respectively arranged above the electric heating component and on the top wall of the inkjet coding slot. The bottom of the linear component located in the inkjet coding slot is connected to the inkjet printer, and the bottom of the other linear component is connected to the photoreceptor.

[0008] Furthermore, the electric heating component includes a support platform and a heating wire. The top of the support platform is provided with a mounting groove, and a plurality of heating wires are connected in the mounting groove at intervals.

[0009] Furthermore, the linear assembly includes a mounting platform, a slider and a connecting rod. A track groove is provided at the bottom of the mounting platform, the slider is slidably connected in the track groove, and the bottom of the slider is fixedly connected to the connecting rod.

[0012] In summary, the present invention has at least one of the following beneficial technical effects:

[0013] 1. This printing device with online coding function can initially dry the printed paper through the installation of electric heating components and photoreceptors. At the same time, the surface of the printed paper presents a light curtain of different intensities according to the different light transmittances of different colors. This allows the photoreceptor to locate the light-colored areas on the printed paper surface, allowing the coder to stably spray the code on the light-colored areas of the printed paper, effectively ensuring the visibility of the code.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] Example:

[0023] Reference Figure 1 - Figure 4 The utility model discloses a printing device with an online coding function, which includes a base 1. A feeding unit 2, a printing unit 3, a drying unit 4, and a receiving unit 5 are sequentially arranged on the top of the base 1 from right to left. A coding unit 6 is arranged between the printing unit 3 and the drying unit 4. The coding unit 6 includes a housing 61, a coding device 62, an electric heating component 63, a linear component 64, and a photoreceptor 65. The electric heating component 63 is arranged on the side of the housing 61 close to the printing unit 3. A coding slot 7 is horizontally opened above the electric heating component 63 in the housing 61.

[0024] There are two linear components 64, which are respectively arranged above the electric heating component 63 and on the top wall of the coding slot 7. The bottom of the linear component 64 located in the coding slot 7 is connected to the coding device 62, and the bottom of the other linear component 64 is connected to the photoreceptor 65.

[0025] In this embodiment, Figure 1 As shown, by arranging the feeding unit 2, the printing unit 3, the drying unit 4 and the receiving unit 5 in sequence from right to left on the top of the base 1, the printing paper can be fed out by the feeding unit 2, then printed with a pattern by the printing unit 3, and then the pigment is dried by the drying unit 4, and finally the printing paper is collected by the receiving unit 5 to realize the whole printing process.

[0026] Since both printing and coding involve brushing pigments onto packaging, this mixing of pigments can affect the visibility of the coding information when the coding overlaps with the dark areas of the printed pattern, thereby affecting the subsequent traceability and compliance of the packaging.

[0027] So in Figure 1It can also be found that a coding unit 6 is arranged between the printing unit 3 and the drying unit 4, and the coding unit 6 is mainly composed of a casing 61, a coding device 62, an electric heating component 63, a linear component 64 and a photoreceptor 65. The electric heating component 63 is arranged on the side of the casing 61 close to the printing unit 3, and a coding slot 7 is horizontally opened above the electric heating component 63 in the casing 61, and then linear components 64 are respectively arranged above the electric heating component 63 and on the top wall of the coding slot 7. The bottom of the linear component 64 located in the coding slot 7 is connected to the coding device 62, and the bottom of the other linear component 64 is connected to the photoreceptor 65.

[0028] At this time, when the printed paper with a pattern enters the coding slot 7, the pattern on the surface of the printing paper will pass over the electric heating component 63, and the electric heating component 63 will initially dry the pigment. While heating and drying the printing paper, the electric heating component 63 will also emit a bright light, which will illuminate the bottom of the printing paper, causing a light curtain to appear on the surface of the printing paper. Because the surface of the printing paper is printed with pigment, and different colors of pigment have different light absorption properties, when the light curtain illuminates the dark area, the brightness of the light curtain on the surface of the printing paper will decrease. Therefore, the brightness of the light curtain in the light area will be much greater than that in the dark area. Therefore, the set photoreceptor 65 will actively move closer to the brighter light source area, thereby moving in conjunction with the inkjet printer 62. When the inkjet printer 62 prints the code, the pigment covers the light area of ​​the printing paper, which can effectively prevent the inkjet code from overlapping with the dark area of ​​the printed pattern, thereby ensuring that the visibility of the inkjet code information is not disturbed.

[0029] In a further preferred embodiment of the present invention, Figure 3 As shown, the electric heating component 63 includes a support platform 631 and a heating wire 632. A mounting groove 8 is provided on the top of the support platform 631. A plurality of heating wires 632 are connected in the mounting groove 8 at intervals.

[0030] In this embodiment, a mounting groove 8 is provided on the top of the support platform 631, and a plurality of heating wires 632 are arranged at intervals in the mounting groove 8, so that the heating wires 632 can heat up and dry the printed paper while emitting light. Since the red light generated by high temperature has the longest wavelength in the visible light, it has a strong penetrating ability and can effectively penetrate the printed paper, thereby ensuring that the photoreceptor 65 can stably track the area with higher light intensity, so as to ensure that the code of the inkjet printer 62 is sprayed on the light-colored area of ​​the printed paper.

[0031] In a further preferred embodiment of the present invention, Figure 4 As shown, the linear assembly 64 includes a mounting platform 641, a slider 642 and a connecting rod 643. A track groove 9 is provided at the bottom of the mounting platform 641. The slider 642 is slidably connected in the track groove 9. The bottom of the slider 642 is fixedly connected to the connecting rod 643.

[0032] The connecting rods 643 of the two linear assemblies 64 are respectively connected to the inkjet printer 62 and the photoreceptor 65, and a crossbar 10 is fixedly connected between the two connecting rods 643;

[0033] The side wall of the mounting platform 641 located outside the housing 61 is fixedly connected to the motor 11 , the output shaft of the motor 11 extends into the track groove 9 and is fixedly connected to the screw rod 12 , which is threadedly connected to the slider 642 .

[0034] In this embodiment, a mounting platform 641 is provided, a track groove 9 is opened at the bottom of the mounting platform 641, a slider 642 is slidably connected in the track groove 9, and a connecting rod 643 is fixedly connected to the bottom of the slider 642. Then, the connecting rods 643 of the two linear components 64 are respectively connected to the inkjet printer 62 and the photoreceptor 65, and a cross bar 10 is fixedly connected between the two connecting rods 643, so that the photoreceptor 65 can track the area with higher light intensity and move with the inkjet printer 62 when moving, thereby ensuring that the code sprayed by the inkjet printer 62 can cover the light-colored area on the surface of the printing paper, which can effectively prevent the code from being interfered with by the dark pigment of the printed pattern and affecting visual observation.

[0035] The motor 11 is fixedly connected to the side wall of the mounting platform 641 located outside the housing 61. The output shaft of the motor 11 extends into the track groove 9 and is fixedly connected to a screw rod 12, which is threadedly connected to the slider 642. The PLC can receive information feedback from the photoreceptor 65 to control the operation of the motor 11, so that the motor 11 drives the screw rod 12 to rotate and control the slider 642 to slide in the track groove 9, thereby adjusting the position of the photoreceptor 65 and the inkjet printer 62.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
