Description

Technical Field

[0001] This utility model relates to the field of inkjet printer technology, and in particular to a coating inkjet printer device and a coating machine. Background Technology

[0002] There are two types of films used in laminating machines: electrostatic film (self-adhesive film, without logo) and low-adhesion film (film surface with adhesive, which is glued to the glass). Low-adhesion film can be customized with logos, but it is more expensive than electrostatic film. Different manufacturers have many different logos, and changing the film on the equipment is time-consuming and laborious. In order to reduce costs, electrostatic film is often used and the logo is printed on-site.

[0003] To improve coding efficiency, mobile inkjet printers (such as CN210526075U) are now widely used. These printers contain multiple movable inkjet terminals that work together to improve coding quality and efficiency. They can also adapt to the needs of different sized goods and different coding positions, making them highly adaptable and cost-effective.

[0004] However, existing multi-head movable inkjet printers have all printheads moving independently without a fixed reference. During adjustment, the absolute position of each printhead must be determined one by one, which is inefficient and prone to individual inkjet printers being missed or incorrectly adjusted. In actual use, the printhead position may shift due to operator accidental touch or equipment vibration, making it difficult to quickly identify the position by its relative position with other printheads. This can delay calibration and lead to overall offset of the printing position. Utility Model Content To address the technical problems of existing multi-head movable inkjet printers in the background art, such as lack of fixed reference, low efficiency in inkjet position adjustment, difficulty in ensuring position accuracy, and easy overall offset of inkjet position, this utility model provides a film-coated inkjet printer.

[0005] The technical solution of this utility model is as follows: This utility model provides a coating inkjet printing device, including a bracket, which is vertically arranged. A first inkjet printer is fixedly installed in the lower part of the bracket, and the first inkjet printer is higher than the bottom of the bracket. A second inkjet printer is slidably installed in the middle part of the bracket, and a third inkjet printer is slidably installed in the upper part of the bracket. The second and third inkjet printers are each connected to a set of synchronous belt assemblies, which fix the first inkjet printer in the lower part of the bracket, making it a reference for adjustment. The second and third inkjet printers slide and adjust in corresponding areas based on this reference, without the need to determine the absolute position of each one, which can greatly improve the adjustment efficiency and reduce the occurrence of missed or incorrect adjustments. At the same time, the fixed position of the first inkjet printer is not easy to shift, and the relative position of the second and third inkjet printers with respect to the first inkjet printer can be quickly identified to see if the second and third inkjet printers have shifted due to accidental touch or vibration, so as to calibrate in time and avoid the overall shift of the printing position.

[0006] Preferably, the first inkjet printer is fixedly mounted on the bracket by the first mounting bracket. The first mounting bracket can provide a stable mounting foundation for the first inkjet printer, enhance the firmness of its connection with the bracket, further ensure the positional stability of the first inkjet printer as a reference, and reduce the reference offset problem caused by loose connection.

[0007] Preferably, a telescopic cylinder is fixedly installed on the first mounting frame. The telescopic cylinder is arranged horizontally, and a coding bracket is fixedly installed on the telescopic end of the telescopic cylinder. The first coding machine is fixedly installed on the coding bracket. The telescopic cylinder can drive the first coding machine to move horizontally, flexibly adjusting its horizontal coding position. This allows the first coding machine to maintain its reference function while adapting to the horizontal coding requirements of different coatings, improving the applicability of the device. It is also convenient to adjust and does not require disassembly and reassembly.

[0008] Preferably, each set of synchronous belt components is fixedly connected to a second mounting bracket, which is slidably connected to the bracket. The second and third inkjet printers are respectively fixedly connected to the corresponding second mounting brackets via telescopic cylinders. The second mounting brackets provide a mounting carrier for the second and third inkjet printers, and work with the synchronous belt components to achieve stable sliding. The telescopic cylinders can also drive the second and third inkjet printers to adjust laterally, realizing multi-dimensional flexible adjustment of the inkjet printing position. At the same time, because there is a reference for the first inkjet printer, the relative position can be more accurately controlled during adjustment, reducing adjustment errors.

[0009] Preferably, a guide rail is fixedly mounted on the bracket, and a slider is fixedly mounted on the second mounting bracket. The slider is slidably connected to the guide rail. The cooperation between the guide rail and the slider can provide guidance for the sliding of the second mounting bracket, ensuring that the second and third inkjet printers move stably vertically along the bracket, avoiding deviation or jamming during sliding, and ensuring the accuracy of their position adjustment.

[0010] Preferably, the synchronous belt assembly includes a driving pulley and a driven pulley rotatably mounted on the bracket. The driving pulley and the driven pulley are connected by a synchronous belt. The driving pulley is connected to a servo motor via a reducer. The second mounting bracket is fixedly connected to the corresponding synchronous belt. The synchronous belt drives the second mounting bracket to move stably, thereby adjusting the height of the second and third inkjet printers. This is more efficient and accurate than manual adjustment, reducing inkjet printing position deviations caused by insufficient adjustment accuracy. Combined with the reference of the first inkjet printer, the second and third inkjet printers can be quickly adjusted to the target relative position.

[0011] Preferably, four positioning frames are fixedly provided on the support along its length. The second inkjet printer is located between two oppositely arranged positioning frames, and the third inkjet printer is located between two other oppositely arranged positioning frames. The positioning frames can limit the sliding range of the second and third inkjet printers, preventing them from sliding out of the preset inkjet area due to over-adjustment or equipment failure.

[0012] Preferably, the positioning frame is a Z-shaped structure. The Z-shaped positioning frame can stably achieve the limiting function without affecting the normal operation of the inkjet printer. Its structure is simple, easy to install, and can be adapted to the installation space of the bracket and the inkjet printer, thus improving the reliability of the limiting function.

[0013] Preferably, the top and bottom of the bracket are fixedly provided with mounting bases, and the mounting bases are provided with several bolt holes. Through the mounting bases and bolt holes, the bracket can be stably installed at the target position, avoiding the overall shaking of the bracket and causing the inkjet printer to shift position. This fundamentally ensures the reference stability of the first inkjet printer and the adjustment accuracy of the second and third inkjet printers.

[0014] A laminating machine includes a laminating inkjet printing device. The upper and lower ends of the laminating inkjet printing device are fixedly installed on the conveyor section of the laminating machine, which enables the inkjet printer to be adapted to the conveyor rhythm of the laminating machine. Combined with the structural advantages of the inkjet printing device itself, it reduces the inkjet printing position deviation, improves the overall quality of laminating inkjet printing, and at the same time reduces the scrap rate caused by inkjet printing problems, thereby improving production efficiency.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are: 1. Fix the first inkjet printer in the lower area of ​​the bracket to make it the reference for adjustment. The second and third inkjet printers slide and adjust in the corresponding area based on this reference. There is no need to determine the absolute position of each one, which can greatly improve the adjustment efficiency and reduce the occurrence of missed or incorrect adjustments. At the same time, the fixed position of the first inkjet printer is not easy to shift. By comparing its relative position with the first inkjet printer, it is possible to quickly identify whether the second and third inkjet printers have shifted due to accidental touch or vibration, and to calibrate them in time to avoid the overall offset of the inkjet printing position.

[0016] 2. Four positioning frames are fixedly installed at intervals along the length of the bracket. The positioning frames can limit the sliding range of the second and third inkjet printers, preventing them from sliding out of the preset inkjet area due to over-adjustment or equipment failure. The Z-shaped positioning frames can stably achieve the limiting function without affecting the normal operation of the inkjet printer. Its structure is simple and easy to install, and it can be adapted to the installation space of the bracket and the inkjet printer, improving the reliability of the limiting function.

[0019] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] Example 1 In a typical embodiment of this utility model, such as Figures 1-3 As shown, a coating inkjet printing device is proposed, including: a bracket 1, a guide rail 2, a first inkjet printer 4, a second inkjet printer 5, and a third inkjet printer 6. The bracket 1 is vertically arranged and has a profile structure. The guide rail 2 is fixedly installed on the bracket 1 and extends along the length of the bracket 1. The first inkjet printer 4, the second inkjet printer 5, and the third inkjet printer 6 are arranged sequentially and spaced apart on the bracket 1 from bottom to top. The first inkjet printer 4 is fixedly connected to the bracket 1, and the second inkjet printer 5 and the third inkjet printer 6 are slidably connected to the guide rail 2 on the bracket 1. The second inkjet printer 5 and the third inkjet printer 6 are each connected to a set of synchronous belt assemblies 7. The synchronous belt assemblies 7 are installed on the bracket 1 to drive the second inkjet printer 5 and the third inkjet printer 6 to move vertically along the guide rail 2 to change the printing position and adapt to the printing requirements of different specifications of glass coating.

[0021] The first inkjet printer 4 is fixedly installed in the lower region of the bracket 1 via the first mounting bracket 8, and the first inkjet printer 4 is higher than the bottom of the bracket 1. The second inkjet printer 5 is slidably installed in the middle region of the bracket 1, and the third inkjet printer 6 is slidably installed in the upper region of the bracket 1. Both the second inkjet printer 5 and the third inkjet printer 6 are connected to the corresponding synchronous belt assembly 7 via the second mounting bracket 9.

[0022] The first inkjet printer 4 is fixed in the lower area of ​​the bracket 1, making it the reference for adjustment. The second inkjet printer 5 and the third inkjet printer 6 slide and adjust in the corresponding area based on this reference. There is no need to determine the absolute position of each one, which can greatly improve the adjustment efficiency and reduce the occurrence of missed or incorrect adjustments. At the same time, the fixed position of the first inkjet printer 4 is not easy to shift. By comparing its relative position with the first inkjet printer 4, it is possible to quickly identify whether the second inkjet printer 5 and the third inkjet printer 6 have shifted due to accidental touch or vibration, and to calibrate them in time to avoid the overall shift of the inkjet printing position.

[0023] Specifically, the first mounting bracket 8 and the second mounting bracket 9 have similar structures. Both the first mounting bracket 8 and the second mounting bracket 9 include a connecting part 19 and a fixing part 20. The connecting part 19 has a U-shaped structure and is fastened to the bracket 1. The connecting part 19 of the first mounting bracket 8 is fixedly connected to the bracket 1 by bolts. The connecting part 19 of the second mounting bracket 9 is fixedly provided with a slider 13 and is slidably connected to the guide rail 2 through the slider 13. At the same time, the connecting part 19 of the second mounting bracket 9 is also fixedly connected to the synchronous belt 16 of the synchronous belt assembly 7 by bolts so as to move with the synchronous belt 16. The fixing part 20 has a plate-shaped structure and is welded and fixed to the side of the connecting part 19 away from the bracket 1 for the installation of the inkjet printer.

[0024] The synchronous belt assembly 7 includes a drive pulley 14, a driven pulley 15, a synchronous belt 16, a servo motor 17, and a reducer 18. The drive pulley 14 and the driven pulley 15 are rotatably mounted on the bracket 1 via pulley seats. The drive pulley 14 and the driven pulley 15 are arranged opposite each other along the length of the bracket 1 and are connected by the synchronous belt 16. The drive pulley 14 is connected to the servo motor 17 via the reducer 18. The reducer 18 is fixedly mounted on the bracket 1 via a reducer seat. The servo motor 17 can drive the drive pulley 14 to rotate around its axis, thereby driving the synchronous belt 16 to rotate, so as to move the corresponding second inkjet printer 5 / third inkjet printer 6 and change the inkjet position.

[0025] It is understood that in other embodiments, a tensioning structure, such as an adjustable tensioning wheel, may also be provided on the bracket 1 to ensure the tension of the timing belt 16 and prevent the timing belt 16 from slipping.

[0026] Since both the second inkjet printer 5 and the third inkjet printer 6 are movable structures, in order to avoid collisions between them, four positioning frames 12 are fixedly installed on the support 1 at intervals along its length. Two positioning frames 12 are arranged in pairs and opposite each other. The second inkjet printer 5 is located between two oppositely arranged positioning frames 12, and the third inkjet printer 6 is located between the other two oppositely arranged positioning frames 12. This is to use the positioning frames 12 to rigidly limit the travel of the second inkjet printer 5 and the third inkjet printer 6, thereby improving the safety of use.

[0027] The positioning frame 12 has a Z-shaped structure and is fixedly installed on the bracket 1 by bolts. The positioning frame 12 is used to contact the second mounting frame 9, thereby limiting the stroke of the second inkjet printer 5 and the third inkjet printer 6 and avoiding direct collision with the second inkjet printer 5 and the third inkjet printer 6.

[0028] To improve adaptability, telescopic cylinders 10 are fixedly installed on the fixing parts 20 of the first mounting bracket 8 and the second mounting bracket 9. The telescopic cylinders 10 are arranged horizontally, and the telescopic ends of the telescopic cylinders 10 are fixedly installed with inkjet brackets 11. The first inkjet printer 4, the second inkjet printer 5, and the third inkjet printer 6 are fixedly installed on the corresponding inkjet brackets 11. Thus, the telescopic cylinders 10 can drive the corresponding first inkjet printer 4, second inkjet printer 5, and third inkjet printer 6 to move horizontally to get closer to / away from the glass surface coating, adapt to glass of different thicknesses, and ensure the inkjet printing quality.

[0029] The top and bottom of the bracket 1 are both fixed with a fixing seat 3. The fixing seat 3 is provided with several bolt holes for bolt installation, thereby fixing the bracket 1 with bolts to restrict the position of the entire coating inkjet printing device.

[0030] Example 2 In another typical embodiment of this utility model, a laminating machine is proposed, which adopts the laminating inkjet printing device mentioned in Embodiment 1. The laminating inkjet printing device is set vertically, and the upper and lower ends of the laminating inkjet printing device are fixedly installed on the conveyor section of the laminating machine by fixing seat 3 and bolts, so as to perform inkjet printing operation on glass laminating.

[0031] The specific working principle is as follows: When the glass height is less than H1, the glass runs on the conveyor section to the coding position, the telescopic cylinder 10 extends, and the first coding machine 4 sprays the LOGO onto the film. When the glass height is greater than H1 and less than H2, the synchronous belt assembly 7 in the middle area of ​​the bracket 1 is activated, which drives the corresponding second mounting bracket 9 to move vertically through the synchronous belt 16, thereby driving the second inkjet printer 5 to move vertically, so as to change the height of the inkjet printing position of the second inkjet printer 5. The telescopic cylinder 10 drives the second inkjet printer 5 to approach the film, and the first inkjet printer 4 and the second inkjet printer 5 work together to spray the LOGO onto the film. When the glass height is greater than H2 and less than H3, the synchronous belt assembly 7 in the middle and upper regions of the bracket 1 is activated, driving the corresponding second mounting bracket 9 to move vertically via the synchronous belt 16. This, in turn, drives the corresponding second inkjet printer 5 and third inkjet printer 6 to move vertically, thereby changing the inkjet printing position height of the second inkjet printer 5 and third inkjet printer 6 respectively. The telescopic cylinder 10 drives the corresponding second inkjet printer 5 and third inkjet printer 6 to approach the film. The first inkjet printer 4, second inkjet printer 5, and third inkjet printer 6 work together to spray the logo onto the film. This can adapt to the inkjet printing needs of glass film of different specifications, with high inkjet printing efficiency, uniform inkjet printing, and effectively improve the aesthetics of the inkjet printing.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
