Description

Technical Field

[0001] The utility model belongs to the technical field of printing flattening, and in particular relates to a traditional printing flattening structure. Background Art

[0002] Flattening in traditional printing refers to the process of printing using a flat-bed press. In this printing method, the printing plate and the impression are both flat. During printing, the printing plate is in direct contact with the impression plate, and the image is transferred to paper or other printing media by applying pressure. This printing method is often used to print various engraved stamps because of its greater pressure and ink consistency.

[0003] In the traditional printing flattening process, there are usually certain limitations in the control of the squeezing force of the flattening structure. Since the design of the flattening device often lacks flexibility and the ability to accurately adjust, it is difficult for the operator to adjust the appropriate pressure according to the characteristics of different papers. This technical limitation leads to the paper being easily over-squeezed and damaged during the printing process, or the expected flattening effect cannot be achieved when the pressure is insufficient, resulting in unstable printing quality. This inconvenience not only affects the printing efficiency and increases the production cost, but also limits the application of the printing process in certain high-quality requirements. Therefore, the traditional printing flattening structure highlights the urgent need for pressure adjustment during use, so as to better adapt to different papers and printing requirements and improve the overall quality and production efficiency of printed products. Utility Model Content

This technical limitation leads to the paper being easily over-squeezed and damaged during the printing process, or the expected flattening effect cannot be achieved when the pressure is insufficient, resulting in unstable printing quality. This inconvenience not only affects the printing efficiency and increases the production cost, but also limits the application of the printing process in certain high-quality requirements.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a traditional printing flattening structure, including a base, both ends of the upper surface of the base are fixedly connected with sliding columns, the surface of the sliding column is slidably connected with a flat plate, the inner upper surface of the sliding column is fixedly connected with a hydraulic rod, the output end of the hydraulic rod is transmission-connected to the upper surface of the flat plate, a groove is opened at one corner of the upper surface of the base, a switch structure is installed inside the groove, a threaded rod is threadedly connected to one corner of the surface of the flat plate, and the upper surface of the threaded rod is fixedly connected with an adjustment handle through a connecting rod.

[0006] Preferably, a paper slot is provided in the middle portion of the upper surface of the base.

[0007] Preferably, both ends of the paper trough are provided with slopes.

[0013] Beneficial effects:

[0014] 1. The utility model provides a threaded rod and an adjusting handle. Before flattening the printing paper, the adjusting handle is rotated according to the material and thickness of the paper, so as to drive the threaded rod to rotate, thereby adjusting the length of the threaded rod extending from the lower surface of the flattening plate. The longer the extension is, the thicker the paper is, and the smaller the flattening force required is. During flattening, the hydraulic rod is extended to slide the flattening plate toward the paper slot to flatten the paper until the threaded rod touches the switch structure, and the switch structure controls the hydraulic rod to stop running, thereby effectively controlling the flattening force of the paper, effectively avoiding the problem that the design of the flattening device often lacks flexibility and precise adjustment ability, and it is difficult for the operator to adjust the appropriate pressure according to the characteristics of different papers. This technical limitation leads to the paper being easily over-extruded and damaged during the printing process, or the expected flattening effect cannot be achieved when the pressure is insufficient, resulting in unstable printing quality. This inconvenience not only affects the printing efficiency and increases the production cost, but also limits the application of the printing process in some high-quality requirements.

[0015] 2. The utility model provides a positioning plate, a positioning hole and a spring telescopic rod. When the flattening force is manually adjusted, the spring telescopic rod is manually shortened to the limit, and the rotating plate rotates with the rotation of the threaded rod. After the adjustment is completed, the spring telescopic rod is loosened, so that the output end of the spring telescopic rod is stuck in the positioning hole of the positioning plate, thereby positioning the structure of the positioning plate and the threaded rod, preventing the threaded rod from rotating due to accidental touch, resulting in inaccurate flattening force of the paper;

[0016] 3. The utility model provides a paper slot to facilitate the positioning of printing paper, and provides slopes on both sides to facilitate the feeding and discharging of printing paper. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6The utility model provides a technical solution: a traditional printing flattening structure, including a base 1, both ends of the upper surface of the base 1 are fixedly connected with sliding columns 4, the surface of the sliding columns 4 is slidably connected with a flat plate 6, the inner upper surface of the sliding columns 4 is fixedly connected with a hydraulic rod 5, the output end of the hydraulic rod 5 is transmission-connected to the upper surface of the flat plate 6, a groove 7 is opened at one corner of the upper surface of the base 1, a switch structure 8 is installed inside the groove 7, a threaded rod 9 is threadedly connected to one corner of the surface of the flat plate 6, and an adjusting handle 13 is fixedly connected to the upper surface of the threaded rod 9 through a connecting rod 12. By setting the threaded rod 9 and the adjusting handle 13, before flattening the printing paper, according to the material and thickness of the paper, the adjusting handle 13 is rotated to drive the threaded rod 9 to rotate, so as to adjust the length of the threaded rod 9 extending from the lower surface of the flat plate 6. The longer it is extended, the thicker the paper is, and the smaller the flattening force required is. During flattening, the hydraulic rod 5 is extended to make the flattening plate 6 slide toward the paper slot 2 to flatten the paper until the threaded rod 9 touches the switch structure 8. The switch structure 8 controls the hydraulic rod 5 to stop running, thereby effectively controlling the flattening force on the paper, and effectively avoiding the problem that the design of the flattening device often lacks flexibility and precise adjustment ability, and it is difficult for the operator to adjust the appropriate pressure according to the characteristics of different papers. This technical limitation causes the paper to be easily over-squeezed and damaged during the printing process, or the expected flattening effect cannot be achieved when the pressure is insufficient, resulting in unstable printing quality. This inconvenience not only affects the printing efficiency and increases the production cost, but also limits the application of the printing process in some high-quality requirements.

[0027] In the utility model, preferably, a paper slot 2 is provided in the middle portion of the upper surface of the base 1 .

[0028] In the present invention, preferably, both ends of the paper slot 2 are provided with slopes 3, and the paper slot 2 is provided to facilitate the limiting of printing paper, and the slopes 3 provided on both sides facilitate the feeding and discharging of printing paper.

[0029] In the present invention, preferably, the hydraulic rod 5 is electrically connected to the external power source via the switch structure 8 .

[0030] In the present invention, preferably, a corner of the surface of the pressing plate 6 is fixedly connected with a fixing column 14 , the top of the fixing column 14 is fixedly connected with a connecting plate 15 , and the lower surface of the connecting plate 15 is fixedly connected with a spring telescopic rod 16 .

[0031] In the present invention, preferably, a positioning plate 10 is fixedly connected between the connecting rod 12 and the threaded rod 9 , and a plurality of positioning holes 11 are formed through the surface of the positioning plate 10 .

[0032] In the utility model, preferably, the spring telescopic rod 16 is engaged and connected to the inside of the positioning hole 11. Through the provided positioning plate 10, positioning hole 11 and spring telescopic rod 16, when the flattening force is manually adjusted, the spring telescopic rod 16 is manually shortened to the limit, and the rotating plate rotates with the rotation of the threaded rod 9. After the adjustment is completed, the spring telescopic rod 16 is released so that the output end of the spring telescopic rod 16 is stuck in the positioning hole 11 of the positioning plate 10, thereby positioning the structure of the positioning plate 10 and the threaded rod 9, preventing the threaded rod 9 from rotating due to accidental touch, resulting in inaccurate flattening force for the paper.

[0033] The working principle and use process of the utility model are as follows: when in use, the printing paper is placed in the paper slot 2 opened in the middle part of the upper surface of the base 1, and the ramps 3 set on both sides facilitate the feeding and discharging of the printing paper. Then, according to the material and thickness of the paper, the adjustment handle 13 is turned to drive the threaded rod 9 to rotate, thereby adjusting the length of the threaded rod 9 extending from the lower surface of the flattening plate 6. The longer the extension, the thicker the paper, and the smaller the flattening force required. Next, turn on the switch structure 8 of the hydraulic rod 5 and the external power supply to extend the hydraulic rod 5, drive the flattening plate 6 to slide toward the direction of the paper slot 2, and flatten the paper. During flattening, the threaded rod 9 touches the switch structure 8, and the switch structure 8 controls the hydraulic rod 5 to stop running, thereby effectively controlling the flattening force on the paper. In order to avoid the threaded rod 9 from rotating due to accidental touch, which causes inaccurate paper flattening force, the spring telescopic rod 16 is manually shortened to the limit, and the rotating disk rotates with the rotation of the threaded rod 9. After the adjustment is completed, the spring telescopic rod 16 is loosened, so that the output end of the spring telescopic rod 16 is stuck in the positioning hole 11 of the positioning disk 10, thereby positioning the structure of the positioning disk 10 and the threaded rod 9. Through the above steps, the problem of paper being squeezed and damaged during the squeezing process, or incomplete squeezing, can be effectively avoided, thereby improving printing quality and efficiency.
