Description

TECHNICAL FIELD

[0001] The utility model relates to printing machine ink technical field, especially a printing machine ink discharge head. BACKGROUND

[0002] Printing machine is divided into upper printing and lower printing, 1. upper printing process: upper printing has paper opening, paper feeding, ink feeding, pressure adding, paper discharging and other links. When printing, ink is sprayed on the printing plate and then transmitted to the paper, realizing mirror image inversion, and finally the paper is displayed after discharging. 2. lower printing process: the process flow of lower printing is similar to that of upper printing, the difference lies in that the contact surface of the paper and the printing plate is opposite during printing. The printing plate of lower printing is opposite to the paper, and the sequence is correct after publishing, without mirror image conversion.

[0003] 1. upper printing machine: the upper printing machine is suitable for conventional printing, such as posters, flyers and the like. The printing machine is large, which ensures the flatness and gloss of the font, and the printing speed is fast.

[0004] 2. lower printing machine: the lower printing machine is characterized by being suitable for printing small and exquisite printing products. It is suitable for printing plants and other links, with small output but high quality.

[0005] The ink of the upper printing process can flow out of the printing machine directly, but the lower printing process needs to use a water pump to suck the ink out, transport it to the ink tank outside the printing machine through a pipeline, and then use it again. However, the end of the ink pipeline is inserted into the ink tank, which will make the ink in the ink tank roll and generate bubbles, causing the volatilization of the ink and affecting the reuse of the ink.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0008] A printing machine ink discharge head, comprising a discharge head body, the discharge head body is a cavity, the upper part of the discharge head body is provided with a feeding pipe head in communication with an ink pipeline, the side wall of the discharge head body is provided with a discharge port, the inside of the discharge head body is provided with a baffle above the discharge port, and the outside of the discharge head body is further provided with a fixing device for fixing the discharge head to the ink tank.

[0009] Further, the fixing device comprises an extension rod, one end of the extension rod is fixedly connected with the discharge head body, and the other end of the extension rod is provided with a hook body.

[0010] Further, the bottom end of the discharge port and the bottom surface of the discharge head body are located in the same plane.

[0011] Further, the discharge port is a rectangle and a semicircle upward from the bottom end.

[0012] Further, the discharge head body is internally provided with a filter screen corresponding to the feeding pipe head.

[0013] Further, the discharge head body comprises an upper cover and a cavity body, the upper cover is provided with the feeding pipe head, the cavity body is provided with the discharge port and a baffle, and the filter screen is arranged in the upper cover.

[0014] Further, the upper cover and the cavity body are clamped.

[0015] In general, the printing machine ink discharge head has the following advantages.

[0016] A printing machine ink discharge head comprises a discharge head body, the discharge head body is a cavity, an upper part of the discharge head body is provided with a feeding pipe head communicated with an ink pipeline, a side wall of the discharge head body is provided with a discharge port, an inner part of the discharge head body is provided with a baffle above the discharge port, and an outer part of the discharge head body is also provided with a fixing device for fixing the discharge head on an ink tank.
