Abstract

The utility model discloses an ink supply system anilox roller structure. The thickness of the lower end of a net wall between each two adjacent inking holes is larger than that of the upper end of each net wall between each two adjacent inking holes. The thickness of each net wall is increased along with increase of the depth along the direction of each inking hole. According to the ink supply system anilox roller structure, the strength of the net wall between each two adjacent inking holes of an anilox roller can be effectively improved, therefore the line number of the anilox roller can be greatly improved, the ratio of openings to the net walls can reach 10 to 1, and therefore accuracy of printing and quality of the printing can be greatly improved.

Description

Ink feeding system anilox roll structure

Technical field

The utility model relates to print field, relates in particular to the ink feeding system anilox roll structure that a kind of flexible printing machine adopts.

Background technology

Printing results from nineteen thirties with anilox roll, it is part crucial in the short circuit ink feeding system, initial anilox roll mainly is to make with metal material, the mesh that processes rectangular pyramid shape at the metal roll surface with electronic engraving or mechanical presses method, it has solved the defective of rubber roll ink transfer poor performance, the printing machine ink spreader is greatly simplified, the uniformity of ink transfer improves a lot, but still exist mesh more coarse, can only make the net roller of low line number, screen density generally is no more than 300 line/inches, and the metal roll surface exists hardness not high, defective such as not wear-resisting.

After nineteen seventies, along with heat plasma spraying technology and laser processing technology reach its maturity, ceramic anilox roller has replaced most of metallic roll, it mainly is to adopt the heat plasma spraying coating process, form ceramic layer at the metal roll surface, with laser processing technology ceramic roll surface is carried out etching processing, finish the engraving of mesh shape.Ceramic anilox roller have wearability good, can carve up to 1500 line/inches even higher netting twine, advantages such as ink transfer is even, but traditional mesh-structuredly still can not satisfy the production demand, when the line number higher words can make the leader thickness attenuation of anilox roll, intensity reduces, be damaged easily, reduced service life.

The utility model content

Technical problem to be solved in the utility model is, a kind of ink feeding system anilox roll structure is provided, and the thickness of the leader lower end between the inking hole is greater than the upper end, along with the leader thickness that gos deep into along the mesh internal direction increases.

Further, described leader cross section is trapezoidal.

Further, described leader top is toward the boss that has a plurality of protrusions, and its cross section is stepped, and a boss cross section of top and close top is " protruding " shape.

Further, the sidewall of described each boss is what tilt.

Further, described leader thickness is 0.5 ~ 0.8 decimillimeter.

Implement the utility model, have following beneficial effect:

Adopt the utility model, can effectively improve the intensity of leader between the anilox roll mesh, thereby can increase substantially the line number of anilox roll, the ratio of opening and leader can reach 10:1, thereby can improve precision and the quality of printing greatly.

The specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the utility model anilox roll schematic diagram, shown in to be covered with inking hole 1(on the anilox roll be mesh).

Ink feeding system anilox roll structure as shown in Figure 2, the thickness of leader 11 lower ends between the inking hole 1 are greater than the upper end, and along with the leader thickness that gos deep into along the mesh internal direction increases, described leader cross section is trapezoidal.

Preferably, as shown in Figure 3, described leader 11 tops are toward the boss that has a plurality of protrusions, and its cross section is stepped, and a boss cross section of top and close top is " protruding " shape.

Further, as shown in Figure 4, the sidewall 111 of described each boss is what tilt.

Further, described leader thickness is 0.5 ~ 0.8 decimillimeter.

Above disclosed only is a kind of preferred embodiment of the utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of doing according to the utility model claim still belongs to the scope that the utility model is contained.
