Abstract

The utility model discloses a pearly-lustre printing ink printing is with china ink groove, which comprises a body, the body is U type groove structure, at the rotatable version printing roller that erects in body top, and version printing roller below sets up the arc, the arc is close to gradually towards version printing roller by lower extreme to the upper end, and the arc lower surface sets up the backup pad, backup pad fixed connection so that leave the clearance between arc and the body in the bottom of body. Through the structure, when the plate printing roller rotates, the ink stored in the body can form stronger convection, so that the pearlescent pigment in the ink in the main pipe is impacted, and the probability of sedimentation and delamination of the pearlescent ink is reduced.

Description

Ink groove for printing pearlescent ink

Technical Field

The utility model relates to an ink printing field, especially a pearl essence is china ink groove for ink printing.

Background

The particularity of pearlescent inks is the use of pearlescent pigments. The mica titanium pearlescent pigment is prepared by using a mica flake as a substrate and coating a transparent or relatively transparent thin layer consisting of titanium dioxide and iron oxide with high refractive index on the surface of smooth mica. When the light irradiates the mica sheet, the mica sheet is like a small transparent mirror, part of the light is reflected, part of the light is refracted to the next interface, and the second partial reflection and partial transmission occur, so that the process continues. It is known from physical optics that light rays reflected at two reflecting surfaces interact with each other, and the interaction result depends on factors such as phase difference, incident angle, refractive index and the like, so that pearlescence of interference characteristics is formed.

In the printing process, the specific gravity of the pearlescent pigment in the pearlescent ink is high, and the pearlescent ink placed in an ink tank for a long time is prone to sedimentation and delamination, so that the printing effect of the pearlescent ink is influenced. The existing mode is that the ink is in a vertical convection state by a heating mode, and then the uniformity of the pearlescent pigment in the pearlescent ink is ensured. However, heating the ink can cause the chemical components of the ink to rapidly volatilize, causing unnecessary physical harm to workers. In addition, the evaporation of the chemical auxiliary agent causes the physical properties of the ink to change, thereby affecting the printing quality.

SUMMERY OF THE UTILITY MODEL

In view of the above insufficiency, the utility model aims to provide an ink tank for printing pearl ink can keep the good convection current state of printing ink under the condition of not heating pearl ink to effectively prevent the subsidence layering of pearl humor.

In order to achieve the above purpose, the technical scheme of the utility model is that:

the utility model provides a pearly-lustre printing ink groove for printing, includes the body, the body is U type groove structure, at the rotatable version printing roller that erects in body top, sets up the arc below the version printing roller, the arc is close to gradually towards the version printing roller by lower extreme supreme end, and the arc lower surface sets up the backup pad, and backup pad fixed connection is in order to make to leave the clearance between arc and the body in the bottom of body.

Furthermore, a plurality of liquid discharge holes distributed along the width direction of the arc plate are formed in one side, close to the upper end of the arc plate, and the liquid discharge holes penetrate through the arc plate.

Furthermore, two side edges of the body are connected with two baffles which are arranged symmetrically to the printing roller, and the baffles are shielded above the printing ink.

The working principle is as follows: because of the viscosity between the ink and the plate printing roller, the ink is dragged in the transfer process of the plate printing roller, and the ink flows forwards after being subjected to the former cause. And after the flowing ink enters the gap which is gradually reduced between the arc-shaped plate and the transfer roller, the ink is discharged from the fine gap between the arc-shaped plate and the plate printing roller in an accelerating manner, so that a strong convection is formed, and the condition that the pearlescent pigment is settled and separated from the ink stored in the body is avoided.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The ink tank for printing pearl ink shown in fig. 1 to 3 includes a body 100. Specifically, the body is of a U-shaped groove structure. The main body stores printing ink. Meanwhile, a plate printing roller 200 is rotatably mounted above the body. And a sheet of arc-shaped plate 300 is disposed below the plate roller. The arc plate is located in the body. And the arc-shaped plate has a lower end to an upper end which gradually approaches towards the plate printing roller, thereby forming a gradually narrowing gap with the plate printing roller. And a support plate 400 for supporting the arc plate is provided on the lower surface thereof. It should be noted that the supporting plate is fixedly connected to the bottom of the body, and a gap through which ink can pass is left between the arc-shaped plate and the body.

As a further improvement of the above embodiment, in order to form multi-angle ink convection, a plurality of drain holes 310 are formed at equal intervals along the width direction of the arc plate on the side close to the upper end of the arc plate 300. The arc-shaped plate is communicated with the liquid discharge hole, so that part of the ink can be quickly flushed out from the liquid discharge hole. In the printing process, ink rushing out from the upper end gap and the liquid discharge hole forms multi-angle impact fluid, so that the effect of multi-directional convection is achieved.

As a further improvement of the above embodiment, in order to reduce the volatilization of the ink during the printing process, two baffles 110 symmetrically arranged with respect to the printing roller are connected to both side edges of the main body, and the baffles block the ink at the upper position to reduce the convection between the ink and the air.
