Description

Leather square screen printing roller

Technical Field

The utility model relates to a leather side's screen print system roller belongs to the technical field of printing reticulation roller.

Background

A typical short ink path ink supply system is adopted in a flexographic printing machine, has a simpler structure and mainly consists of an ink tank, a rubber roller, a doctor blade and an anilox roller. Among them, the anilox roller is a core component of the flexographic printing machine, which is responsible for uniformly transferring a certain amount of ink to the printing plate.

The printing demand of a leather square net exists at present, and it needs to print the square body of matrix arrangement, and the tradition mode is that latticed storage ink tank is directly processed, and it is difficult to realize holding the circulation of china ink, leads to printing homogeneity relatively poor, appears easily printing square body part disappearance scheduling problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the not enough of above-mentioned prior art, block the problem that formula net oil storage ink storage groove can influence printing quality to the tradition, provide a leather square screen printing system roller.

In order to achieve the above purpose, the utility model discloses the technical scheme who adopts is:

a leather square screen printing roller comprises a main body of the screen roller, a first thread rib and a second thread rib which is crossed with the first thread rib at right angles are arranged on the roller surface of the main body of the screen roller, a square oil storage tank which is distributed in a grid shape is formed between the first thread rib and the second thread rib,

the second thread rib is provided with a continuous rib which is connected with the first thread rib in a crossed way and a separation groove which is separated from the first thread rib, the continuous rib and the separation groove are continuously distributed along the direction of the first thread rib in a staggered way,

two through gaps which are oppositely arranged are arranged between the separation groove and the first thread rib, any square oil storage groove is provided with a group of through gaps which are angularly symmetrical, and the first thread rib forms a coherent ink passage.

Preferably, the rib direction of the first thread rib forms an included angle of 45 degrees with the axial direction of the net roller main body.

Preferably, the outer peripheral wall surface of the first threaded bead and the outer peripheral wall surface of the second threaded bead are respectively provided with a side chamfered surface.

The beneficial effects of the utility model are mainly embodied in that:

1. the printing of leather square patterns can be realized, the printing requirements of the square leather patterns are met, the oil circuit through the angle end symmetrical through-connection gaps can be realized, the ink storage uniform requirements of each square oil storage tank are met, the printed patterns are clear and attractive, and local deletion is not easy to occur.

2. Possess the design of side chamfer face, increased the structural strength of screw thread muscle, satisfied the shaping demand of less interval portion, be difficult for appearing deformation, prolonged the life of leather side screen print system roller.

Detailed Description

The utility model provides a leather square screen printing system roller. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.

The utility model provides a leather square screen printing system roller, includes the net roller main part 10, is equipped with first screw thread muscle 1 on the roll surface of net roller main part 10 and with 1 looks right angle cross's of first screw thread muscle second screw thread muscle 2, forms latticed square oil storage tank 3 that distributes between first screw thread muscle 1 and the second

screw thread muscle

2, and 3 looks independent divisions of square oil storage tank are traditionally held, consequently hold the china ink volume and have the difference, the even difference of pattern appears printing easily, some square region of printing exist promptly and leak.

In the scheme, as shown in fig. 1 and fig. 2, the second threaded rib 2 is provided with a continuous rib 4 connected with the first threaded rib 1 in a cross manner and a separation groove 5 separated from the first threaded rib, the continuous rib 4 and the separation groove 5 are distributed along the direction of the first threaded rib in a staggered and continuous manner, two through gaps 6 are oppositely arranged between the separation groove 5 and the first threaded rib, any square oil storage groove 3 is provided with a set of through gaps 6 with angular symmetry, and the first threaded rib 1 forms a coherent ink passage.

The specific implementation process and principle description are as follows:

referring to fig. 1 and 2, a through ink passage is formed between the spiral ribs of the first thread rib 1 through the separation groove 5, so that ink can be communicated and leveled, the printing uniformity is ensured, meanwhile, a cross connection part is formed between the continuous rib 4 and the first thread rib 1, and the stable molding of a group of corner ends of the square oil storage groove 3 is met.

The net roller main body 10 of the scheme prints the formed patterns, the square printing areas are uniform, the communicating ink channels formed by the local through gaps 6 are uniform, the whole body is attractive, and the outline is clear and recognizable.

In a particular embodiment the ribs of the first threaded rib 1 are angled at 45 deg. to the axial direction of the wire roll body. The method can meet the printing requirement of the regular patterns, and the printed product has the regular dermatoglyph patterns after being cut by the direct transverse cutter and the longitudinal cutter.

In a preferred embodiment, as shown in fig. 2, the outer peripheral wall surface of the first threaded bead 1 and the outer peripheral wall surface of the second threaded bead 2 are provided with side chamfered surfaces 7, respectively.

Specifically speaking obviously, the spacing distance is shorter between the general square pattern, adopts the design of the first screw thread muscle 1 of equidimension and second screw thread muscle 2 can lead to the screw thread muscle structural strength relatively poor, causes the printing deformation easily, and effective life is shorter, adopts the design of side chamfer face 7 in the present case, can improve screw thread muscle structural strength, satisfies less interval shaping demand, has prolonged life.

In addition, leather square pattern needs the non-regular linear marginal edge, generally adopts the higher printing ink of consistency, and the excessive stress when printing ink printing realizes special marginal edge shaping, and printing ink printing stress is too big can appear in the vertical wall ink groove traditionally, and the excessive pattern of messenger is thoughtlessly turned over to the excessive, and this side chamfer face 7 can make outer fringe excessive ink volume less, prevents that the excessive marginal edge from being linked together and thoughtlessly turned over.

Can discover through the above description, the utility model relates to a leather square screen printing system roller can realize leather square pattern printing, satisfies the printing demand of square leather pattern, link up the clearance through the angle end symmetry and can realize that the oil circuit link up, satisfies the even demand of black that holds of each square oil storage tank, and the printing pattern is clear pleasing to the eye, is difficult for appearing local disappearance. Possess the design of side chamfer face, increased the structural strength of screw thread muscle, satisfied the shaping demand of less interval portion, be difficult for appearing deformation, prolonged the life of leather side screen print system roller.

The above technical solutions of the present invention have been fully described, and it should be noted that the present invention is not limited by the above description, and all technical solutions formed by equivalent transformation or equivalent transformation adopted by the spirit of the present invention in the aspects of structure, method or function by those of ordinary skill in the art all fall within the protection scope of the present invention.
