Problems solved by technology

[0003] At present, due to the high power of the printing machine itself, the existing sun-drying boards often lead to unstable voltage during operation and unnecessary losses. At the same time, when the ultraviolet light is too much, it will affect the service life of the lamp tube.

Abstract

The invention discloses a voltage-stabilizing printing-down machine. The machine comprises a machine body, and a cover plate is installed at the top of the machine body. Telescopic rods are arranged at the two sides of the cover plate and the machine body, and an operation table is arranged on the front end face of the machine body. A control panel is arranged at the top of the operation table, and a handle is arranged at one end of the cover plate and located at the top of the operation table. A vacuum pump is arranged at one side of the machine body. A connecting block is connected to the rear end face of the machine body. Voltage-stabilizing diodes are arranged at the joints of the lamp tubes and a power supply at the two sides in the machine body, thereby enabling the machine to have an automatic voltage-stabilizing performance to a certain extent, preventing the damages caused by excessive voltage to the machine from affecting the work efficiency, and improving the safety. Becausethe luminous efficiency and the service life of the lamp tubes are easily influenced by corrosion of strong light, the top of the cover plate is coated with an anti-ultraviolet coating, thereby fullyprotecting the radiation resistance of the lamp tube, achieving the dustproof effect, and achieving the silencing effect.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a voltage-stabilized printing machine. Background technique [0002] The printing machine is a kind of contact exposure imaging equipment used to make printing plates. It uses pressure (including atmospheric pressure and mechanical pressure) to make the original plate and the photosensitive plate closely bonded, so that the image on the original plate can be accurately exposed through photochemical reactions. Made on a photosensitive plate. The plate printing machine is mainly composed of a light source device, an exposure chamber, a vacuum chamber, an electrical part, and a machine base. The plate printing machine is mainly used for making printing plates (PS plates, screen plates, etc.) The pressure makes the original plate and the photosensitive plate fit closely, so that the image on the original plate can be accurately printed on the photosensitive plate through ...
