An ammonia printing machine for indoor office

Abstract

The invention relates to the technical field of office equipment, and discloses an ammonia printing machine for indoor office use, including a body, a liquid filling tank is fixedly installed on the upper left of the inner cavity of the body, and the bottom of the liquid adding tank passes through a liquid adding device A liquid control device is fixedly connected, and the top of the liquid adding tank is fixedly connected with a liquid inlet hopper. The liquid adding device includes an insulating plate, and the top and bottom of the insulating plate correspond to the bottom of the liquid adding tank and the liquid control area respectively. The top of the device is fixedly connected. The indoor office has an ammonia printing machine. Through the cooperation between the liquid adding tank, the liquid adding device and the liquid control device, when the liquid level inside the liquid storage tank drops, the suspension of the floating plate is used to drive the baffle to Move down, add the solution in the liquid addition tank to the liquid storage tank through the curved groove, so as to keep the solution in the liquid storage tank at the same concentration all the time, and then keep the acidity of the dampening solution at a suitable pH value, effectively avoiding Dust appears on the layout of the printing machine, keep the cleanliness of the layout of the printing machine.

Description

technical field [0001] The invention relates to the technical field of office equipment, in particular to an ammonia printing machine for indoor office use. Background technique [0002] Printing machine is a device that transfers the graphics on tracing paper to photosensitive materials by means of exposure, that is, printing paper, and then develops blueprints through development. Although computer technology is widely used and computer-aided manufacturing technology is perfect, The workload of duplicating drawings has been reduced, but it is necessary for workers to process and produce drawings in a short period of time. The cost of copying drawings is cheap and the printing machine is irreplaceable within a certain period of time. Playing a role for a long time, the printing machine is widely used in indoor office and industrial production. [0003] During the use of the existing ammonia printing machine, because the acidity of the dampening solution is too weak, the fo...

Problems solved by technology

[0004] The invention provides an ammonia printing machine for indoor office, which has the advantages of maintaining the cleanliness of the layout of the printing machine and improving the quality effect of copying drawings by the printing machine, and solves the problems caused by the existing ammonia printing machine during use. The acidity of the dampening solution is too weak, and the formation of a hydrophilic colloid layer is slow, which cannot supply and make up for the inorganic salt layer in the blank of the printing plate in time, resulting in a decrease in the hydrophilic and oleophobic function of the blank of the printing plate. The corrosion effect of the oxide film is large, and it is easy to make the layout glow under the pressure conflict, and the stored moisture is small, which will cause dust on the layout of the printing machine when inking, and the existing printing machine is in the alignment of the line plate and the dot plate and the mesh plate and the mesh plate. In the case of both line plates, the concentration of the dampening solution used is the same, so when the concentration of the dampening solution is low, the hydrophilic and oleophobic function of the blank part of the printing plate will decrease, resulting in poor printing of some patterns on the printing machine. Clearly, when the concentration of the dampening solution is high, the layout will glow under the pressure conflict, and the stored moisture will cause dust on the layout of the printing machine, which will affect the quality of the drawing copied by the printing machine
