Description

Technical Field

[0001] The utility model relates to the technical field of dampening solution supply for printing presses, and particularly relates to a centralized dampening solution supply device for offset printing presses. Background Art

[0002] The dampening solution, also known as wetting solution, fountain solution, or fountain solution concentrate, contains wetting agents that change the surface tension of the dampening solution on the printing plate surface. The dampening solution with added wetting control components can also help reduce the amount of ink while obtaining clear dots and vivid colors. Its pH buffer system can provide a continuous and stable pH value (4.5 - 5.5), and it is suitable for various water qualities (the problem of soft and hard water has been solved by a unique chemical formula that can make both soft and hard water reach a certain intermediate state, making it easier to control conductivity). The anti-corrosion components help protect your machine. It is a highly concentrated product that needs to be diluted before use.

[0003] Among them, Chinese Patent (CN220639188U) discloses a centralized dampening solution supply device for a printing press, including a liquid storage tank. A baffle is installed at the inner top of the liquid storage tank. Threaded holes are opened at the four corners of the top of the baffle. A cover plate is installed on the top of the liquid storage tank. Four supply pipes are evenly installed on one side of the outer part of the liquid storage tank. Through the designed centralized dampening solution supply device for a printing press of the utility model, the dampening solution addition pipes on four printing presses can be connected through four supply pipes, and the dampening solution can be supplied to the four printing presses simultaneously, or the dampening solution can be supplied to the opposite printing presses as needed, realizing the centralized supply of the dampening solution. There is no need to configure a separate dampening solution supply device for each printing press, thereby reducing the usage cost and improving the operation convenience.

[0004] The deficiencies of the centralized dampening solution supply device for the printing press in the above comparative document are as follows: The dampening solution generally needs to be diluted and stirred before use. If it is directly used without dilution and mixing, it will corrode the printing press and affect the printing quality of the printing press.

[0005] Therefore, we have designed a centralized dampening solution supply device for offset printing presses. Summary of the Utility Model

[0006] The technical problem solved by the utility model is to provide a centralized dampening solution supply device for offset printing presses with relatively high practicability, which can be operated simply and has a relatively simple structure, and solves the problem that the printing press will be corroded if it is directly used without dilution and mixing as mentioned in the above background art.

[0007] To achieve the above objectives, the present utility model is realized through the following technical solutions: A centralized supply device for dampening solution of an offset printing machine, including a cover plate. A servo motor is fixedly installed at the center of the cover plate. A drive rod is splined to an output end of the servo motor. One end of the drive rod is fixedly connected to a gear. One side of the surface of the gear is meshed with a first toothed disc. A fixed column is fixedly connected to the surface of the first toothed disc. The other side of the surface of the gear is meshed with a second toothed disc. A collar is fixedly connected to the bottom of the second toothed disc. The fixed column passes through the second toothed disc and the collar. A water pump is fixedly installed on one side of the top of the cover plate. An output pipe of the water pump is communicated with a conduit. One end of the conduit penetrates and is connected to the cover plate.

[0008] Optionally, the input end of the water pump is communicated with a tee pipe. The other two ends of the tee pipe penetrate and are connected to a cylinder. The tee pipe can simultaneously suck dampening solution and water, reducing the number of water pumps.

[0009] Optionally, a threaded rod is threadedly connected to the surface of the cylinder. One end of the threaded rod is rotatably connected to a movable plate through a bearing. The movable plate can be driven by the threaded rod, and thus the dosage of the liquid flowing in the cylinder can be controlled. A hose penetrates and is connected to the top of the cylinder.

[0010] Optionally, a stirring blade is fixedly connected to one side of the surface of the fixed column. A limiting ring is fixedly connected to the other side of the surface of the fixed column. The limiting ring can prevent the collar from descending. The collar is rotatably connected to the surface of the limiting ring. A U-shaped rod is fixedly connected to the surface of the collar.

[0011] Optionally, a storage bucket is fixedly connected to the surface of the cover plate through bolts. A discharge port is opened at the center of the bottom of the storage bucket. A four-way pipe is fixedly connected to the surface of the discharge port. The four-way pipe can be connected to four printing machines.

[0012] Optionally, support columns are fixedly connected to the bottom of the storage bucket. The support columns raise the height of the storage bucket to facilitate the connection of the four-way pipe at the bottom of the storage bucket to the printing machine. The bottom of the support column is fixedly connected to a bottom plate.

[0013] The present utility model provides a centralized supply device for dampening solution of an offset printing machine, having the following beneficial effects:

[0014] 1. For this centralized supply device for dampening solution of an offset printing machine, through the settings of the servo motor, drive rod, gear, first toothed disc, fixed column, second toothed disc, collar, stirring blade and U-shaped rod, when the servo motor is turned on, it drives the gear to rotate through the drive rod, and then drives the first toothed disc and the second toothed disc to rotate in opposite directions, causing the fixed column and the collar to rotate in reverse. At the same time, the stirring blade and the U-shaped rod are driven to rotate in opposite directions, which can better stir the liquid inside the storage bucket, playing a good role in stirring the dampening solution and improving the speed of stirring and mixing the diluted dampening solution.

[0015] 2. The dampening solution centralized supply device of the offset printing machine, through the settings of a water pump, a tee pipe, a cylinder, a threaded rod, a movable plate and a hose, inserts two hoses into the dampening solution storage container and the water container respectively. By rotating the threaded rod, the movable plate blocks or does not block the inner wall of the cylinder, restricting the dosage of the liquid passing through the cylinder, and adjusting the dosage extraction of the dampening solution and water according to the dilution ratio required. At the same time, after the dampening solution and water are extracted, they are introduced into the storage bucket through a conduit, which facilitates the control of the dosage of the dampening solution and water and reduces the working intensity of the staff for manually proportioning and diluting the dampening solution.
