Description

Technical Field

[0001] The utility model relates to the technical field of digital printing machines, and more specifically to a cloth pressing structure for digital printing machines. Background Art

[0002] The working principle of digital printing is basically the same as that of an inkjet printer. In short, digital printing is to input the pattern into the computer in digital form, edit and process it through the computer printing color separation tracing system, and then control the computer to control the micro-piezoelectric inkjet nozzle to spray the special dye directly onto the textile to form the required pattern. Different post-processing is then performed according to the tissue composition of different fabrics. During the printing process, the fabric needs to be pressed to ensure its stability during printing.

[0003] The existing cloth pressing structure of the digital printing machine is mainly composed of a soft roller. When in use, since the roller is exposed to the air for a long time, some dust or foreign matter will more or less adhere to the outside of the roller. It is necessary to clean the dust and foreign matter on the outside of the roller in time. Since the roller of the existing cloth pressing structure is not convenient to disassemble, the staff can only lift the roller first, and then wipe the outside of the roller with a rag or wet wipes. The operation is time-consuming and laborious, which reduces the convenience of cleaning the roller. At the same time, since the roller cannot be removed for cleaning, the cleaning effect of the roller is poor, which affects the normal use of the roller.

[0004] In view of this, we propose a cloth pressing structure for a digital printing machine. Utility Model Content

[0026] See also Figure 1-4 ,The utility model provides a technical solution:

[0027] A cloth pressing structure for a digital printing machine comprises a printing machine body 1, two groups of U-shaped frames 2 are movably arranged on the upper side of the printing machine body 1, and installation boxes 3 are fixedly arranged on the inner sides of the two groups of U-shaped frames 2, and a rotating rod 4 is movably arranged on the outer side of the installation box 3, and a plurality of groups of pressing rollers 5 are sleeved on the outer side of the rotating rod 4, and two groups of sliders 6 are movably arranged on the inner side of the installation box 3, and a connecting block 7 is fixedly arranged on the lower side of the two groups of sliders 6, and the connecting block 7 movably penetrates the installation box 3 and extends to the outside, and a mounting block 8 is fixedly arranged on the lower side of the connecting block 7 located on the outer side of the installation box 3, and a mounting hole 9 for docking the rotating rod 4 is opened on the outer side of the installation block 8, and the inner side of the installation box 3 is provided with a plurality of pressing rollers 5, and the mounting hole 9 for docking the rotating rod 4 is opened on the outer side of the installation box 3. Two groups of springs 10 are provided, one end of the two groups of springs 10 are respectively connected to the two sides of the installation box 3, and the other end of the spring 10 is connected to the slider 6. The spring 10 does not deform in the initial state. When the rotating rod 4 is disassembled, the movement of the slider 6 will squeeze the spring 10. At this time, the spring 10 is deformed, which makes it convenient to disassemble the rotating rod 4. When the rotating rod 4 is installed, the elastic potential energy of the spring 10 is released, which can drive the two groups of sliders 6 to move and reset. The movement of the slider 6 drives the connecting block 7 and the installation block 8 to move, so that the rotating rod 4 can be quickly installed through the two groups of installation blocks 8, thereby improving the installation convenience and installation stability.

[0028] Specifically, a through slot for the butt-jointed connecting block 7 is provided through the lower side of the installation box 3. The through slot 7 can facilitate the back-and-forth sliding of the connecting block 7, thereby ensuring the normal use of the device.

[0029] Furthermore, a mounting plate 12 is movably provided on the inner side of the mounting box 3, and a movable rod 13 is fixedly provided on the outer side of the mounting plate 12. The movable rod 13 movably passes through the mounting box 3 and extends to the outside, and a handle 14 is fixedly provided on the outer end of the movable rod 13 on the outer part of the mounting box 3. A movable plate 11 is rotatably provided on the outer side of the slider 6, and the other side of the movable plate 11 is rotatably connected to the mounting plate 12. By pressing the handle 14, the slider 6 and the mounting block 8 can be easily driven to move, thereby improving the convenience of operation.

[0030] It is worth mentioning that a slide bar 15 is fixedly provided inside the installation box 3 , and the slide bar 15 movably passes through the slider 6 . The slide bar 15 can limit the slider 6 , so that the slider 6 slides along the slide bar 15 , further improving the movement stability of the slider 6 .

[0031] It is worth noting that two sets of limiting rings 16 are provided on the outer fixed sleeve of the rotating rod 4, and the limiting rings 16 can limit the mounting block 8, which improves the convenience of installing the mounting block 8 and ensures the installation effect of the rotating rod 4 and the pressure roller 5.

[0032] In addition, fixed blocks 17 are fixedly provided on both sides of the printing machine body 1, movable blocks 18 are fixedly provided on both sides of the U-shaped frame 2, and an electric push rod 19 is provided on the upper side of the fixed block 17. One end of the electric push rod 19 is connected to the fixed block 17, and the other end of the electric push rod 19 is connected to the movable block 18.

[0033] Working principle: When in use, turning on the electric push rod 19 through an external power supply can easily drive the movable block 18 and the U-shaped frame 2 to move downward. When the U-shaped frame 2 moves, it drives the installation box 3 to move downward. When the installation box 3 moves downward, it drives the connecting block 7 and the pressing roller 5 to move downward, so that the cloth can be pressed. When the pressing roller 5 needs to be cleaned, just grab the handle 14 and press it. The handle 14 moves to drive the movable rod 13 and the mounting plate 12 to move. When the mounting plate 12 moves, it drives the movable plates 11 on both sides to move. The movable plate 11 moves and drives the slider 6 to slide on the outside of the slider 15. When the slider 6 moves, it drives the connecting block 7 and the mounting block 8 to move until the mounting block 8 is moved out from the outside of the rotating rod 4. At this time, the rotating rod 4 and the rotating rod 5 can be removed for cleaning.
