Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a mesh belt conveyor for a roll-to-roll inkjet printing equipment. Background Technology

[0002] Inkjet equipment comes in a variety of specifications. There are continuous jet printers, which use pressure to continuously eject ink from a single nozzle to form patterns. There are also ink-on-demand printers, where ink is ejected under constant internal pressure to form characters or graphics on a moving surface. A digital signal on paper generates a drop of ink, thus allowing for accurate printing of patterns.

[0003] Currently, inkjet printing equipment requires a conveyor to transport the film containing the printed pattern. However, due to the stretchability of the conveyor belt, it is prone to varying degrees of deviation after stretching. This results in inconsistent belt tension during operation, causing lateral skewing and bulging, which can lead to the image being printed outside the material or the material bulging scratching the inkjet printhead, affecting print quality and potentially damaging the expensive printhead.

[0004] Therefore, it is necessary to provide a conveyor belt device for roll-to-roll inkjet printing equipment to solve the above-mentioned technical problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1-4This utility model provides a conveyor belt device for a roll-to-roll inkjet printer: It includes two mounting plates 1, arranged opposite each other. Each mounting plate 1 has a rotating plate 2 and a fixing component. Two conveyor rollers 3 and a curved roller 4 are rotatably connected between opposite sides of the two rotating plates 2. A conveyor belt 5 is connected between the outer surfaces of the two conveyor rollers 3 and the curved roller 4. Two worm gears 6 are fixedly fitted onto the outer surface of the curved roller 4, meshing with a worm 9. An adjusting frame 7 is fixedly connected to opposite sides of the two rotating plates 2. A rotating shaft 8 is rotatably connected inside the adjusting frame 7, with one end of the rotating shaft 8 rotatably passing through the adjusting frame 7 and fixedly connected to an adjusting... The joint ring 10 and the rotating shaft 8 are equipped with a worm gear 9. One of the rotating plates 2 is equipped with a drive assembly. Through the arrangement of the mounting plate 1, worm wheel 6, adjusting frame 7 and worm gear 9, the angle of the curved roller 4 can be adjusted, and the curved roller can correct the tension in the middle and at both ends of the conveyor belt 5. This ensures that the conveyor belt 5 remains uniform and stable on the printing platform, so that it does not bulge or deviate during use. This solves the problem that the conveyor belt 5 deviates after stretching due to its extensibility, causing the tension of the conveyor belt 5 to be inconsistent, resulting in left and right deviations and bulging, which can lead to the printing of material or the material bulging causing scratches on the printhead, affecting the printing quality and potentially damaging expensive printheads.

[0030] The mounting plate 1 has a rotating groove 11, and the rotating plate 2 is rotatably connected to the rotating groove 11. The front side of the mounting plate 1 has a connecting groove 12, which is connected to the rotating groove 11.

[0031] The drive assembly includes a motor 13, which is fixedly installed on one side of one of the rotating plates 2. The output end of the motor 13 is fixedly connected to one end of one of the conveyor rollers 3. Through the setting of the drive assembly, one of the conveyor rollers 3 can be driven to rotate, and with the cooperation of the conveyor belt 5, it can drive the other two conveyor rollers 3 and the curved roller 4 with a transmission wrap angle greater than or equal to 120 degrees to rotate synchronously.

[0032] The fixing assembly includes several fixing slots 14 and annular slots 15. The fixing slots 14 are all opened on the rotating plate 2. A limiting rod 16 is movably inserted inside one of the fixing slots 14. A fixing rod 17 is fixedly connected to one end of the limiting rod 16. A fixing block is provided on the fixing rod 17, and its length is greater than the depth of the fixing slot 14. The annular slot 15 is opened on the front of the mounting plate 1. The limiting rod 16 is movably connected to the annular slot 15. An annular cylinder 18 is fixedly connected to the front of the mounting plate 1. A spring 19 is fixedly connected inside the annular cylinder 18. The spring 19 is sleeved on the outer surface of the fixing rod 17. The other end of the fixing rod 17 movably passes through the annular cylinder 18. Through the setting of the fixing assembly, the position of the bending roller 4 and the two conveying rollers 3 can be easily adjusted, so that they can guide, limit and convey printing materials of different materials without disassembling or replacing the conveying device. This is convenient, quick and saves time and effort, thereby improving the practicality of the device.

[0033] Working principle: In use, the device is installed on the inkjet printing equipment via two mounting plates 1. Then, the position of the curved roller 4 can be adjusted according to the material to be printed. That is, when inkjet printing is required for film and paper materials, since it has winding and unwinding mechanisms at both ends, there is no need to use a conveyor belt 5. In order to avoid the film and paper materials being suspended below during inkjet printing, which would affect the printing quality, the fixed rod 17 can be manually pulled when the material to be printed is being conveyed. This will cause the limiting rod 16 to move. After the corresponding spring 19 is compressed, the end of the limiting rod 16 away from the fixed rod 17 moves out from the fixed groove 14 into the annular groove 15 and onto the fixed rod 17. The limiting block is moved out of the annular cylinder 18. After the limiting fixation of the two rotating plates 2 is released, the fixing rod 17 is manually rotated to drive the limiting rod 16 to rotate. The fixing block on the fixing rod 17 abuts against the annular cylinder 18 to prevent the limiting rod 16 from resetting under the action of the spring force 19. Then, the rotating plate 2 is rotated to drive the two conveying rollers 3, the bending roller 4 and the conveyor belt 5 to rotate synchronously. The bending roller 4 can be rotated to the top so that the conveyor belt 5 located above is arc-shaped. The fixing rod 17 can then be rotated again to reset it. Under the action of the spring force 19, the limiting rod 16 is re-inserted into the corresponding fixing groove 14 to fix and limit the adjusted rotating plate 2.

[0034] When inkjet printing is required on sheet materials, the motor 13 can be started when the two conveyor rollers 3 are above the curved roller 4 and in a horizontal position. This will drive one of the conveyor rollers 3 to rotate, and with the cooperation of the other conveyor roller 3 and the curved roller 4, the conveyor belt 5 will rotate, thus conveying and printing the sheet material. During use, to avoid the stretching of the conveyor belt 5, which could cause different degrees of deviation after stretching, resulting in inconsistent tension of the conveyor belt 5 during equipment operation, causing it to slant and bulge, leading to the image printing outside the material, or the material bulging causing it to scratch the inkjet printhead, affecting print quality and potentially damaging the expensive printhead, the two adjusting rings 10 can be manually rotated. This will drive the rotating shaft 8 and the worm gear 9 to rotate. The worm gear 9 drives the meshing worm wheel 6 to rotate, and the worm wheel 6 drives the curved roller 4 to rotate, thus adjusting the tension of the conveyor belt 5.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
