Abstract
The utility model discloses a tensile fluctuation elimination device which is used in a computer printing-plate adjusting multicolor gravure press, a support wall panel is arranged on a frame which is positioned between a feeding unit of the gravure press and a firs-color printing unit, an upper carrying roll and a lower carrying roll are arranged on the support wall panel, and the upper carrying roll and the lower carrying roll are mutually alternately arranged in a definite angle and a definite distance, the support wall panel is fixed connected through the utilization of a positioning support shaft, roll shafts and bearings are arranged in the upper carrying roll and the lower carrying roll. With the utility model, the tensile force of printing drum materials is stably processed, and the materials are evenly stretched under the condition of constant tensile force, thereby the tensile-force fluctuation status of the materials is eliminated. Compared with the prior art, the utility model can make stable printing registration of the computer printing-plate adjusting multicolor gravure press, and then the printing precision is improved, good printing effect is obtained.
Description
One, technical field
The utility model relates to a kind of intaglio press, specifically relates to a kind of computer to version multicolour photogravure machine.
Two, background technology
At present, computer to the printing cylinder material of version multicolour photogravure machine after through its blowing unit and feed unit, enter before the first look printing element, all carry out the control of the big minor swing of tension force, its produce that tension fluctuation changes reason mainly contain: the variation from big to small of printing its diameter of cylinder material, its circumference cambered surface irregular, its degree of tightness inconsistent (former batch tension force inconsistent), unreel many reasons such as controlling organization and the variation of mistake material roller mechanical friction power, though pass through the processing of the tension control mechanism of blowing unit and feed unit, but also exist the tension fluctuation phenomenon and before arriving printing plate cylinder, also have long distance, and its signal source is far away apart from printing plate cylinder, and printing material also has bigger fluctuation generation and elastic properties of materials distortion (stretching) inconsistent (its stretching differ activation make tension fluctuation) when entering the first look printing element.Thereby trapping printing stability is bad, and the chromatography precision of printing is low to shift uniformity, less stable with printing ink, and printing quality has been subjected to certain influence.
Three, utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of device that is used for computer to the printing the eliminated cylinder material tension fluctuation of version multicolour photogravure machine is provided.
The purpose of this utility model realizes by following technical solution: a kind of computer is to the tension fluctuation cancellation element of version multicolour photogravure machine, on the feed unit of this intaglio press and the frame between the first look printing element, supporting wall plate is set, on described supporting wall plate, install deflector roll and lower guide roll, and go up deflector roll and lower guide roll has a certain degree and arrange apart from the space; Described supporting wall plate uses the positioning supports axle fixedly connected, and described going up in deflector roll, the lower guide roll all is equipped with roll shaft and bearing.
After adopting the utility model structure, the printing cylinder material is handled through the tension force of blowing unit, feed unit, enter many again and go up deflector roll, lower guide roll, roller transfer by upper and lower deflector roll, its tension force has obtained handling stably and material is stretched under constant tension force uniformly, thereby eliminated the tension fluctuation situation of this material.Therefore, the utility model compared with prior art, it can make computer stable to the trapping printing of version multicolour photogravure machine, and then improves printing precision, has obtained good printing effect.
Four, description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is that the utility model computer is to the tension fluctuation cancellation element of version multicolour photogravure machine and the structural representation of installation.
Fig. 2 is the A-A cutaway view of Fig. 1.
Five, the specific embodiment
With reference to Fig. 1, Fig. 2 as can be known, the utility model computer is made of supporting wall plate 3, last deflector roll 11 (many), lower guide roll 4 (many), positioning supports axle 5 parts such as (many) the tension fluctuation cancellation element of version multicolour photogravure machine.Wherein supporting wall plate 3 is installed on the feed unit 2 and the frame 6 between the first look printing element 1 of computer to version multicolour photogravure machine, on described supporting wall plate 3, install deflector roll 11 (many) and lower guide roll 4 (many), and go up deflector roll 11 and lower guide roll 4 and have a certain degree and arrange apart from the space; Described supporting wall plate 3 uses positioning supports axle 5 (many) fixedly connected, and described going up in deflector roll 11, the lower guide roll 4 consists of: roll shaft 8 and bearing 9.
This computer is made up of three parts version multicolour photogravure machine tension control system: blowing unit 13 unreel controlling organization 10, feed unit 2, tension fluctuation cancellation element.The tension force control principle is: unreel the tension variation (this moment tension variation bigger) of controlling organization 10 when controlling uncoiling by automatic tension system or other modes, feed unit 2 makes printing material obtain the stretching of inhomogeneous (tension fluctuation is big) in certain flattening and the material certain limit, and the tension fluctuation cancellation element makes the printing material that enters printing plate cylinder obtain one section tension force control stably and the equal substantially stretching of tension force size during with printing.
Through computers version multicolour photogravure machine unreeled controlling organization 10 at printing cylinder material 12, after the feed unit 2, though its tension force passes through blowing, the processing of the tension control mechanism in the feed unit, but because printing its diameter of cylinder material variation from big to small, its circumference cambered surface irregular, its degree of tightness inconsistent (former batch tension force inconsistent), unreel many reasons such as controlling organization and the variation of mistake material roller mechanical friction power, but also exist the tension fluctuation phenomenon, also has long distance before arriving printing plate cylinder simultaneously, and its processing signals spacing from printing plate cylinder with far away, printing material was bigger in addition when material entered the first look printing element fluctuation generation and elastic properties of materials distortion (stretching) are inconsistent, still can produce the tension fluctuation phenomenon.Enter deflector roll, the lower guide roll gone up of the present utility model then, roller transfer by upper and lower deflector roll, material obtains one section tension force control stably and the equal substantially even stretching of tension force size during with printing, thereby has eliminated the tension fluctuation situation that printing material enters printing state.When entering the first look printing element of this intaglio press at last, fluctuation can not appear in the tension force of printing cylinder material again, and the trapping printing of material has obtained stable.Thereby improved printing precision, obtained good printing effect.
