Abstract

The utility model relates to an intaglio press with an automatic chromolithographer. The utility model comprises a photoelectric signal circuit and a motor control circuit. An unwinding roller (2) and a winding roller (3) which are respectively arranged on both ends of a shell (1), and flattening guide roller groups (4) are arranged on both ends of the shell. A plurality of press plate devices and a plurality of guide roller groups (5) which can rise and fall are arranged between the flattening guide roller groups (4) and the winding roller (3) at intervals. The press plate device are composed of press pressure rubber rollers (6) and press plate rollers (7). The key is that a magnetic approach switch (8) is arranged under each of the press plate rollers (7). A metal block (9) is arranged on the press plate rollers (7). Photoelectric detectors (10) are respectively arranged in both sides of the position in which base materials between the press device and the guide roller groups (5) pass. The utility model can automatically regulate wrong plates, reduce labor strength, enhance work efficiency, and avoid waste result from the wrong plates.

Description

Intaglio press with automatic chromolithographer

The utility model relates to a kind of printing machinery, refers to a kind of intaglio printing press that can adjust the tool automatic overprint device that occurs wrong edition in the colored printing automatically especially.

The machinery of process printing at present all is printings of being finished a color by a plurality of forme rollers and squeegee pressure rubber roller separately generally, be that base material or the material that is printed print a kind of color at one group of forme roller and squeegee pressure rubber roller place, stamp another color again at next forme roller and squeegee pressure rubber roller place, through repeatedly printing, finish whole printing process, whole process is finished continuously, for example the cover printing device of cycle type intaglio press generally is to finish in the middle of stroke distance of version of the same colour and another look version by changing printing element, the deflector roll of an energy lifting is installed in the middle of two look versions, if with the deflector roll segment distance that rises, two looks just have the corresponding changing of the relative positions so, if descend a bit, pattern is the changing of the relative positions in the opposite direction, the intaglio printing press that uses all is to transfer version by hand basically now, promptly adjust the deflector roll of energy lifting, because pattern is in continuous transmission, have only the eyesight of personnel selection to observe wrong version situation, so brought very big labour intensity to the printing worker, and after finding wrong edition, the people adjusts again, the existing considerable part of base material produces wrong version, cause the considerable part product rejection, waste very big.

Goal of the invention of the present utility model is to disclose the intaglio printing press that a kind of tool is revised wrong version automatically.

Operation principle of the present utility model is to utilize photosignal to detect wrong version situation, when printing element stamps first kind of color, both when one week of forme work, just print out a complete pattern, outer rim at pattern adds a series of rectangular pattern of printing, one spacing of determining is arranged between the pattern of each rectangle, the rectangle perforation on similar film both sides, when base material is printed second kind of color, definite spacing will be filled up, when whole base material when printed several look superpositions get up to be a complete multicolour pattern, a series of rectangle pattern should be a complete colour code, should have not a particle of the space between each colour code, wrong version takes place as the arbitrary chromatography process in printing process, then back one colour code and last colour code then will overlap in one section zone, corresponding then two colour codes must have the other end not connect fully, at this moment be located at space between the colour code of light source through not linking together of base material one side and give optical signal of photodiode of base material another side, the signal of telecommunication that photodiode produces is given the deflector roll enabling signal of energy lifting through control circuit, automatically adjust the stroke between two look versions, make wrong version recover normal.

Provide concrete structure of the present utility model in detail below in conjunction with accompanying drawing.

Accompanying drawing is a structural representation of the present utility model.

The realization the technical solution of the utility model is: comprise the photosignal circuit, circuit for controlling motor, establish let off roll 2 and wind-up roll 3 at casing 1 two ends, flatten guide roller set 4 near being provided with in the casing of let off roll 2 one ends, between flattening guide roller set 4 and wind-up roll 3, be provided with several printing plate devices and several liftable guide roller set 5, printing plate device is that squeegee pressure rubber roller 6 and forme roller 7 constitute, and printing equipment and guide roller set 5 are spaced apart; The base material that let off roll 2 is sent is sent into adjacent guide roller set 5 send into first color printing device after flattening guide roller set 4 flattenings after again, then send into follow-up printing equipment and guide roller set 5, last chromaticity printing finishes the back by wind-up roll 3 rollings, key of the present utility model is to be provided with a magnetic approach switch 8 below each print roller 7, corresponding print roller 7 is provided with a metal derby 9, the both sides, position that base material between printing equipment and guide roller set 5 passes through are respectively equipped with photoelectric detection system 10, and photoelectric detection system 10 is relative with photodiode and constitute by light source; When print roller 7 is rotated printing, metal derby 9 on it is along with rotation, when the edge one of metal derby 9 during near switch 8, magnetic switch 8 is connected under the effect in metal derby and magnetic field, give signal of photodiode, make photodiode work, be in wait state, as the wrong version of chromaticity printing, then signal of telecommunication of photodiode generation rotates the motor 11 in guide roller set and 5 by circuit for controlling motor, and the tooth bar 13 that the gear driven one on the turning cylinder of motor 11 is located on guide roller set 5 housings 12 moves up and down, and the deflector roll 14 that then fixes on the tooth bar 13 moves up and down simultaneously, and then adjust two stroke distances between the look version, reach the purpose of correcting wrong version.

The concrete structure of above-mentioned liftable guide roller set (5) is: be provided with a motor 11 on the support shell 12 of guide roller set (5), gear on the power transmission shaft of motor 11 is meshed with the tooth bar of setting 13 that can slide on shell 12, is fixed with a deflector roll 14 on the tooth bar 13; Motor 11 rotating band carry-over bars 13.

The forme roller 7 that rotates whenever circles, photoelectric detection system detects a signal, give instruction by the magnetic approach switch 8 that is installed in forme roller 7 belows detection time, instruction time has just entered checkout gear with the detection zone that is adjusted at base material and has been as the criterion, if the pattern chromatography is accurate, two kinds of colour codes are provided with the district that overlaps, and promptly also do not have simultaneously blank spaces between two kinds of colour codes, then photoelectric detection system does not produce the signal of telecommunication, and printing machine normally moves.

Wrong version when the utility model can be adjusted chromatography automatically so alleviated working strength of workers greatly, has improved operating efficiency simultaneously greatly, has reduced the generation of wrong version, has avoided the significant wastage that causes because of wrong version.
