Description

Technical Field

[0001] This application relates to the field of printing technology, and more specifically, to a water receiving structure based on a printing press water tank. Background Technology

[0002] In the printing industry, dampening solution and ink are the two major factors determining the quality of printed materials. The dampening solution is first mixed, cooled, and filtered by a specialized device before being delivered to the corresponding water fountain in the printing press. It then flows through a complete dampening system onto the printed material. The ink fountain on the printing press is usually located below the water fountain. When the ambient temperature is higher than the water fountain temperature, condensation forms on the outer wall of the water fountain. When there is enough condensation, it drips into the ink fountain, causing ink emulsification and preventing proper ink color adjustment.

[0003] A water-drip device for a rotary printing press, disclosed in CN202782114U, includes a printing plate cylinder and a water roller and a water transfer roller disposed beside the printing plate cylinder. A water bucket is provided below the water transfer roller, and the water bucket is connected to a water tank through a water pipe. A water tray is provided below the water bucket to collect the mist droplets generated at the bottom of the water bucket.

[0004] However, if the condensate drips onto the water tray too quickly, a small amount of condensate will still splash out of the tray, and the splashed condensate will drip into the ink fountain, affecting the printing quality of the paper. Utility Model Content

[0031] Example 1

[0032] Reference Figure 1-4 ,

[0033] A water-receiving structure based on a printing press water tank includes: a hydrophilic fabric 2, a first fixing block 33, a second fixing block 34, and a water tray 3; in other embodiments, the hydrophilic fabric 2 is a non-woven fabric. The water tray 3 is disposed below the water tank 1; the first fixing block 33 and the second fixing block 34 are disposed within the water tray 3; one end of the hydrophilic fabric 2 is connected to the first fixing block 33, and the other end of the hydrophilic fabric 2 is connected to the second fixing block 34; both the first fixing block 33 and the second fixing block 34 have threaded holes on their surfaces facing away from the water tray 3, and screws are used to pass through the hydrophilic fabric 2 and thread the screws into the threaded holes to fix the hydrophilic fabric 2 onto the first fixing block 33 and the second fixing block 34. The hydrophilic fabric 2 is located on the end of the first fixing block 33 and the second fixing block 34 facing away from the bottom surface of the water tray 3, and the length of the hydrophilic fabric 2 is greater than the distance between the first fixing block 33 and the second fixing block 34. By placing a hydrophilic cloth 2 inside the water tray 3, the hydrophilic cloth 2 can quickly absorb the condensate when it drips onto the paper, thereby reducing condensate splashing and improving the printing quality of the paper.

[0034] Specifically, the side of the water tray 3 facing away from the water hopper 1 is provided with a water outlet pipe 31. After the hydrophilic cloth 2 absorbs sufficient condensate, the condensate will overflow outward relative to the hydrophilic cloth 2, and the overflowing condensate can be discharged out of the water tray 3 through the water outlet pipe 31.

[0035] Specifically, guide rods 32 are installed inside the water tray 3; two guide rods 32 are installed along the length of the water tray 3; the first fixing block 33 and the second fixing block 34 are slidably connected to the two guide rods 32. After the printing operation of the printing machine is completed, the worker can control the first fixing block 33 and the second fixing block 34 to move closer to each other, while the hydrophilic cloth 2 located between the first fixing block 33 and the second fixing block 34 is folded and bent due to its own softness. The worker can squeeze the bent hydrophilic cloth 2 to squeeze out the condensed water in the hydrophilic cloth 2, and then move the first fixing block 33 and the second fixing block 34 to the two ends of the guide rod 32.

[0036] Example 2

[0037] See attached document Figure 5-7

[0038] The difference from Embodiment 1 is that one of the guide rods 32 is replaced with a lead screw 35, which passes through the water pan 3. A motor 36 is installed at the end of the lead screw 35 extending outside the water pan 3, and the output end of the motor 36 is connected to the lead screw 35 via a coupling. A first fixing block 33 is fixed inside the water pan 3, and has a straight hole with a diameter larger than that of the lead screw 35 to prevent interference when the motor 36 drives the lead screw 35 to rotate. A second fixing block 34 slides against the guide rod 32 and is also threadedly connected to the lead screw 35, so that when the motor 36 drives the lead screw 35 to rotate, the second fixing block 34 can move along the extension direction of the guide rod 32. A flexible rope 4 and a limiting plate 5 are also provided inside the water pan 3; the limiting plate 5 is fixed inside the water pan 3 with glue, and two of each are provided. Each limiting plate 5 has two through holes with a diameter larger than that of the guide rod 32 and the lead screw 35. The limiting plate 5 is used to limit the second fixing block 34 and the first fixing block 33. The distance between the two limiting plates 5 is greater than the distance between the first fixing block 33 and the second fixing block 34. One flexible rope 4 is threaded through one side of the hydrophilic fabric 2, and the other flexible rope 4 is threaded through the other side of the hydrophilic fabric 2, so that the longitudinal section of the hydrophilic fabric 2 is wavy. The first fixing block 33 and the second fixing block 34 are provided with through holes, the diameter of which is greater than the diameter of the flexible rope 4. The two ends of the flexible rope 4 pass through the through holes and are attached to the limiting plate 5. The flexible rope 4 is used to guide the hydrophilic fabric 2. When the second fixing block 34 is close to the first fixing block 33, a compression area 341 is formed between the first fixing block 33 and the second fixing block 34, and the hydrophilic fabric 2 is located in the compression area 341. When the motor 36 drives the lead screw 35 to rotate, the second fixing block 34 will move closer to or further away from the first fixing block 33 along the extension direction of the guide rod 32. When the second fixing block 34 approaches the first fixing block 33, the second fixing block 34 and the first fixing block 33 can squeeze the condensate in the hydrophilic cloth 2, allowing some of the condensate in the hydrophilic cloth 2 to flow outwards. The condensate flowing out of the hydrophilic cloth 2 is discharged into the water tray 3 through the water outlet pipe 31. After squeezing, the motor 36 drives the lead screw 35 to rotate, and the second fixing block 34 moves away from the first fixing block 33 until the second fixing block 34 abuts against the limiting plate 5 at the end away from the first fixing block 33. At this point, the second fixing block 34 stops moving, and the hydrophilic cloth 2 unfolds.

[0039] Specifically, the water hopper 1 has barbed hooks 11 on both sides, and the barbed hooks 11 are plate-shaped structures. The water tray 3 has hook-rings 37 on both sides; the hook-rings 37 are plate-shaped structures. When the hook-rings 37 are connected to the barbed hooks 11, the water tray 3 is located below the water hopper 1. When installing the water tray 3, the worker only needs to hang the hook-rings 37 on the barbed hooks 11, which is simple to operate. In this embodiment, a total of 4 barbed hooks 11 are provided, two on one side of the water hopper 1, and the number of barbed hooks 11 and hook-rings 37 is equal. In other embodiments, the barbed hooks 11 are hooks with adhesive surfaces, which can be directly pasted onto the water hopper 1.

[0040] Specifically, the water tray 3 has a condensate-receiving surface 38 and a baffle 39 surrounding the edge of the surface 38; the baffle 39 has a plate-like structure. The baffle 39 is inclined relative to the surface 38 so that when condensate drips onto the baffle 39, the condensate can slide down the baffle 39 onto the surface 38. In this embodiment, the baffle 39 is inclined at 110° relative to the surface 38.

[0041] Specifically, the projected area of ​​the bearing surface 38 on the ground is larger than the projected area of ​​the water hopper 1 on the ground, and the water pan 3 can completely catch the condensate formed at the bottom of the water hopper 1 to prevent the condensate from dripping directly onto the ink fountain.

[0042] Specifically, water tray 3 is made of plastic.
