Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and in particular to a drying component for an intelligent water-based ink printing press. Background Technology

[0002] Water-based ink printers, due to their use of water-based ink pigments, offer advantages such as environmental friendliness and are widely used in fields such as cardboard box printing. However, water-based inks contain a large amount of water and alcohol, and their drying speed is significantly affected by workshop temperature. A relative humidity of 60% to 85% is more suitable. When there are large temperature differences between winter and summer, higher temperatures lead to faster water evaporation, while lower temperatures result in slower ink drying. This greatly affects printing quality and speed. To ensure printing quality and improve production efficiency, intelligent water-based ink printers usually need to be equipped with drying components. However, traditional drying methods have many shortcomings. For example, the common hot air convection evaporation drying method is prone to problems such as increased hot air humidity leading to lower drying efficiency. It may also cause uneven heating of the printed product surface, resulting in uneven shrinkage, curling, and wrinkling after drying, affecting product quality.

[0003] Most existing drying components use high-pressure hot air to perform the drying operation. However, high-pressure hot air may blow away undried ink, making the dried ink marks blurry and affecting the clarity and integrity of the printed pattern, reducing the visual effect and readability of the printed matter. At the same time, high-pressure hot air blowing directly onto the surface of the printed matter may cause the printed matter to shift on the conveyor, resulting in edge curling. This not only affects the drying effect but may also cause the printed matter to overlap, further damaging the printed pattern and affecting subsequent processing.

[0004] Therefore, there is an urgent need to provide a drying component for an intelligent water-based ink printer to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a drying component for an intelligent water-based ink printing machine.

[0006] To solve the above technical problems, the present invention provides a drying component for an intelligent water-based ink printing machine, including a mounting box, wherein multiple support blocks are fixedly connected to the bottom of the mounting box, and a feed inlet and a discharge outlet are provided at the rear end of the mounting box. The mounting box has an internal mounting slot, on which a drying component and a tensioning component are mounted. The drying component can dry the printed paper, and the tensioning component can adjust the tension of the printed paper.

[0007] The present invention is further configured as follows: the drying assembly includes multiple mounting rods fixedly connected between the two sides of the mounting groove, each mounting rod having a guide roller rotatably connected to its outer surface; a sealing groove is provided at the front end of the mounting box; hydraulic rods are installed on both sides of the outer wall of the mounting box; multiple bolts are threadedly connected between two hydraulic rods and the mounting box; a fixing block is fixedly connected to the front end of each of the two hydraulic rods; a sealing door is fixedly connected between the inner sides of the two fixing blocks; multiple electric heating tubes are installed at the upper end of the mounting groove and inside the sealing door; a connecting pipe is fixedly connected to one side of the mounting box; an mounting pipe is fixedly connected to the side of the connecting pipe near the mounting groove; and two air jet pipes are fixedly connected to one side of the mounting pipe.

[0008] The above technical solution involves first feeding the printing paper into the mounting box through the inlet, then bringing the lower end of the printing paper into contact with the upper ends of multiple guide rollers until the printing paper reaches the front end of the mounting groove. The printing paper is then pulled vertically downwards and passes through the center of two air jets. At this point, the printing paper passes through the tensioning assembly in an S-shape until it exits through the discharge port. The printing paper is then mounted onto the receiving device. Simultaneously, multiple electric heating tubes are activated to perform the first drying of the printing paper. The printing paper then passes through the two air jets via the receiving device, where hot air is emitted, achieving a secondary drying process.

[0009] The present invention is further configured such that every two mounting rods and guide rollers are on the same plane, and the dimensions of the plurality of mounting rods and guide rollers are all equal.

[0010] The above technical solution can provide a uniform and stable support surface for printing paper, so that the paper will not shake or deviate during the conveying process due to unevenness or differences in roller diameter, and ensure that the paper moves smoothly along the predetermined path, which is conducive to improving the consistency and stability of the drying effect.

[0011] The present invention is further configured such that: a sealing ring is fixedly connected to the rear end of the sealing door, and the inner wall of the sealing groove is tightly fitted with the outer wall of the sealing ring.

[0012] The above technical solution can effectively prevent heat loss during the drying process, allowing more heat generated by the electric heating tube to be concentrated in the installation tank, maintaining a higher temperature in the drying environment, thereby accelerating the drying speed of printed paper and improving the efficiency of the entire drying process.

[0013] The present invention is further configured such that the two air jets are respectively disposed at the upper and lower ends of the printing paper, and the two air jets are parallel to each other.

[0014] The above technical solution enables simultaneous heating and drying of both sides of the paper, which can significantly shorten drying time and improve production efficiency. It can also avoid uneven drying on both sides of the paper due to single-sided drying, thereby reducing the risk of paper deformation and curling, and ensuring the flatness of the paper and printing quality.

[0015] The present invention is further configured such that: the tensioning assembly includes two mounting blocks fixedly connected to one side of the mounting groove, each mounting block having a sliding groove, each sliding groove having a slider slidably connected to its inner wall, a fixing plate fixedly connected between one side of the two sliders, a connecting rod fixedly connected to the side of the fixing plate away from the slider, and a tensioning roller rotatably connected to the outer surface of the connecting rod.

[0016] With the above technical solution, since the tension roller is connected to the fixed plate through the connecting rod, and the sliders on both sides of the fixed plate can slide freely in the groove of the mounting block, the tension roller will generate a downward force under its own weight. When the paper feeding speed changes or the tension fluctuates, the tension roller will automatically move up and down to adjust the tension of the paper and ensure that the paper always maintains appropriate tension.

[0017] The present invention is further configured such that the outer walls of the two sliders are tightly fitted to the inner side of the groove.

[0018] The above technical solution can effectively suppress the lateral sway of the tension roller, ensure that the paper tension is uniform and stable during the conveying process, and avoid misregistration or wrinkles caused by tension fluctuations.

[0019] The beneficial effects of this utility model are as follows: 1. By setting up a drying component, multiple electric heating tubes can operate simultaneously, which can quickly increase the temperature inside the installation box, allowing the moisture in the ink on the surface of the printing paper to evaporate rapidly. In addition, the jet pipe sprays hot air for secondary drying, further accelerating the drying process and significantly shortening the drying time. 2. By setting up a tensioning component, this utility model can reduce the deformation and blurring of printed patterns caused by paper shaking, wrinkles, etc. At the same time, it can prevent ink from bleeding due to paper movement before it dries, which helps to maintain the clarity and integrity of the printed pattern and improve the quality of printed products.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] Please see Figure 1 - Figure 6A drying component for an intelligent water-based ink printing machine includes a mounting box 1. Multiple support blocks 2 are fixedly connected to the bottom of the mounting box 1. An inlet 3 and an outlet 4 are located at the rear end of the mounting box 1. An installation groove 5 is located inside the mounting box 1. A drying component 6 and a tensioning component 7 are installed on the installation groove 5. The drying component 6 includes multiple mounting rods 601 fixedly connected between the two sides of the installation groove 5. Guide rollers 602 are rotatably connected to the outer surfaces of the mounting rods 601. A sealing groove 603 is located at the front end of the mounting box 1. Hydraulic rods 604 are installed on both sides of the outer wall of the mounting box 1. Multiple bolts 605 are threadedly connected between two hydraulic rods 604 and the mounting box 1. Fixing blocks 606 are fixedly connected to the front ends of the two hydraulic rods 604. The inner sides of the two fixing blocks 606... A sealing door 607 is fixedly connected between the mounting slot 5 and the mounting box 1. Multiple electric heating tubes 608 are installed on the upper end of the mounting slot 5 and inside the sealing door 607. A connecting pipe 609 is fixedly connected to one side of the mounting box 1. An mounting pipe 6010 is fixedly connected to the side of the connecting pipe 609 near the mounting slot 5. Two air jet pipes 6011 are fixedly connected to one side of the mounting pipe 6010. First, the printing paper is fed into the mounting box 1 through the feed inlet 3. Then, the lower end of the printing paper abuts against the upper ends of multiple guide rollers 602 until the printing paper moves to the front end of the mounting slot 5. Then, the printing paper is pulled vertically downwards and passes through the center of the two air jet pipes 6011. At this point, the printing paper is passed through the tensioning assembly 7 in an S-shape until it exits through the discharge outlet 4. Finally, the printing paper... Installed on the receiving device, simultaneously, multiple electric heating tubes 608 are activated, enabling them to perform the first drying of the printing paper. Subsequently, the printing paper passes through two air jets 6011 via the receiving device, where hot air is emitted for a secondary drying. Each pair of mounting rods 601 and guide rollers 602 are on the same plane, and all mounting rods 601 and guide rollers 602 are of equal size. This provides a uniform and stable support surface for the printing paper, preventing swaying or deviation during transport due to unevenness or differences in roller diameter. This ensures the paper moves smoothly along the predetermined path, improving the consistency and stability of the drying effect. After sealing the door 607... The end is fixedly connected with a sealing ring, and the inner wall of the sealing groove 603 is tightly fitted with the outer wall of the sealing ring; this effectively prevents heat loss during the drying process, allowing more heat generated by the electric heating tube 608 to be concentrated in the mounting groove 5, maintaining a higher temperature in the drying environment, thereby accelerating the drying speed of the printed paper and improving the efficiency of the entire drying process; two air jets 6011 are respectively set at the top and bottom ends of the printed paper, and the two air jets 6011 are parallel to each other; this allows for simultaneous heating and drying of both sides of the paper, which can not only significantly shorten the drying time and improve production efficiency, but also avoid uneven drying on both sides of the paper due to single-sided drying, thereby reducing the risk of paper deformation and curling, and ensuring the flatness of the paper and printing quality; like Figure 3 and Figure 6 As shown, the drying component 6 can dry the printed paper, and the tensioning component 7 can adjust the tension of the printed paper. The tensioning component 7 includes two mounting blocks 701 fixedly connected to one side of the mounting groove 5. Each mounting block 701 has a sliding groove 702. A slider 703 is slidably connected to the inner wall of each sliding groove 702. A fixing plate 704 is fixedly connected between the two sliders 703 on one side. A connecting rod 705 is fixedly connected to the side of the fixing plate 704 away from the slider 703. A tensioning roller 706 is rotatably connected to the outer surface of the connecting rod 705. Since the tensioning roller 706 is connected to the connecting rod 705... Connected to the fixed plate 704, the sliders 703 on both sides of the fixed plate 704 can slide freely in the grooves 702 of the mounting block 701. The tension roller 706 will generate a downward force under its own weight. When the paper feeding speed changes or the tension fluctuates, the tension roller 706 will automatically move up and down to adjust the tension of the paper and ensure that the paper always maintains appropriate tension. The outer walls of the two sliders 703 are tightly fitted to the inner side of the grooves 702. This can effectively suppress the lateral sway of the tension roller 706 and ensure that the tension of the paper is uniform and stable during the feeding process, which can avoid misregistration or wrinkles caused by tension fluctuations.

[0024] In use, the printing paper is first fed into the mounting box 1 through the feed inlet 3. Then, the lower end of the printing paper is brought into contact with the upper ends of multiple guide rollers 602 until the printing paper moves to the front end of the mounting groove 5. The printing paper is then pulled vertically downwards and passes through the center of the two air jets 6011. At this point, the printing paper is passed through the tensioning assembly 7 in an S-shape until it exits through the discharge outlet 4. The printing paper is then mounted onto the receiving device. At the same time, multiple electric heating tubes 608 are activated to perform the first drying of the printing paper. The printing paper then passes through two air jets 6011 via the receiving device. At this time, the two air jets 6011 will spray hot air to achieve the purpose of secondary drying. Since the tension roller 706 is connected to the fixed plate 704 via the connecting rod 705, and the sliders 703 on both sides of the fixed plate 704 can slide freely in the grooves 702 of the mounting block 701, the tension roller 706 will generate a downward force under its own weight. When the paper feeding speed changes or the tension fluctuates, the tension roller 706 will automatically move up and down to adjust the tension of the paper and ensure that the paper always maintains appropriate tension.
