Problems solved by technology

When changing the order of traditional gravure printing equipment, it is necessary to clean the ink pump and the pipeline. This requires the use of workshop transportation tools such as trolleys to move the ink pump to a specific cleaning position for cleaning, that is, to do the ink pump. Several times of moving are time-consuming, resulting in a long order change time and affecting production efficiency

Embodiment Construction

[0015] Embodiments of the present invention are described in detail below.

[0016] Such as figure 1 , figure 2 As shown, the present invention is an ink supply device of a multi-print station gravure printing machine, which is used to transport the ink raw material from the ink tank (not shown) to the ink tank of the multi-print station gravure printing machine, and the ink supply device includes a pneumatic diaphragm Pump 10, one end is connected with described pneumatic diaphragm pump 10 and the other end stretches into the ink suction pipe 15 in the described ink barrel, the first end is connected with the outlet of pneumatic diaphragm pump 10 and the other end stretches into described ink groove ( Figure not shown) ink supply tube 16.

[0017] By using the pneumatic diaphragm pump 10 to replace the traditional electric ink pump, since the pneumatic diaphragm pump works through two one-way valves and the pump body, it can provide a lot of power, that is, it can output v...

Abstract

The invention discloses an ink supply device of a photogravure press with multiple printing seats, which is used for transporting ink materials into an ink tank of the photogravure press with multiple printing seats from an ink barrel. The ink supply device comprises a pneumatic diaphragm pump, a bag filter, a trolley with an arc-shaped gap, a blotting pipe and an ink supply pipe, wherein one end of the blotting pipe is connected with the pneumatic diaphragm pump, and the other end of the blotting pipe extends into the ink barrel; and one end of the ink supply pipe is connected with a delivery outlet of the pneumatic diaphragm pump, and the other end of the ink supply pipe extends into the ink supply pipe of the ink tank. By using the pneumatic diaphragm pump, the invention can avoid blocking the ink pump, thereby preventing the stoppage of the photogravure press with multiple printing seats. Because the pneumatic diaphragm pump has higher output pressure, and a filtering device can be additionally arranged on an output position; the granularity of filtered ink can be ensured to meet printing requirements.

Description

Technical field [0001] The invention relates to a multi-printing seat gravure printing machine, and in particular to an ink supply device for a multi-printing seat gravure printing machine. Background technique [0002] At present, multi-printing base gravure printing machines generally use anti-riot electric centrifugal pumps connected to the printing press to supply ink to the gravure printing equipment. During the ink supply process, the electric centrifugal pump often trips due to excessive load or the bearing of the centrifugal pump is blocked. The power supply of the electric centrifugal pump is provided online by the gravure printing machine, so when the electric centrifugal pump trips, the entire line Gravure printing presses will be shut down. Downtime will affect the production efficiency of the equipment to a great extent and cause the loss of paper ink. [0003] Multi-printing seat gravure printing machine The electric centrifugal ink pump equipped with the mul...
