Description

The four-color process unit

Technical field:

The utility model relates to a kind of four-color process unit.

Background technology:

1. traditional double-colored or multicolour offset press first unit and second unit are one, and this structure is unfavorable for changing unit quantity, are not easy to transportation, install and maintenance; 2. offset press rolls pillow and clean to be shuts down the back and clean by artificial, causes personal injury easily, is easy to generate also that to roll pillow dirty, the influence printing; 3. offset press impression cylinder grippers sheet and bite-block are narrow.When the magnanimous octavo 440 * 305mm paper of printing, two ends have the wide trimming of 36mm can't hold paper in the month, cause paper-tear picture easily, paper feed fault rate height, influence printing; 4. 52 traditional type offset presses are maximum to be magnanimous six open-width faces with paper web face 520 * 370mm, and 52 type offset presses can't print the often positive four open-width facial tissues of 560 * 400mm of use of user; 5. offset press chain delivery device changes the collection car and shuts down and to change, and when number to be printed is big, shuts down and changes the collection car and influence printing efficiency, also causes printing ink imbalance easily, produces useless.

Summary of the invention:

For solving the problem of above-mentioned existence, the utility model provide a kind of be convenient to installation, maintenance, transport and have automatic cleaning roll pillow function, paper feed fault rate low, be difficult for producing the useless four-color process unit of opening, be fit to positive four open-width faces printing, this printing unit separates traditional offset press first unit and second unit, second unit is made the standard press group, couple together and constitute the four-color process unit with two standard sets printing unit and paper supply printing unit, collection printing unit; The purpose of this utility model is achieved through the following technical solutions: the four-color process unit: by two standard press groups (1,11), collection printing unit, paper supply printing unit constitutes, the standard press group comprises wallboard, printing cylinder, printing cylinder comprises impression cylinder, transfer platen, plate cylinder, transfer roller, impression cylinder, transfer platen, plate cylinder, transfer roller is fixed between right wallboard and the left wallboard, left side in the standard press group, the end face of right wallboard is shaped on connecting hole respectively, standard press group (1) is connected with standard press group (11) by bolt, standard press group (11) is connected with collection printing unit by bolt, standard press group (1) is by bolt and the winding of paper supply printing machine, standard press group (1) is connected with preceding base by bolt with paper supply printing unit, and standard press group (11) is connected with rear base by bolt with collection printing unit.

Be equipped with not shut down on collection printing unit and change collection car device, not shutting down and changing collection car device is that support fixedly is equipped with in both sides above the collection dolly, and interim strippers is inserted on the support, and detachable.

Be provided with on the pillow rolling of transfer platen and plate cylinder and roll the pillow cleaning device, described roll the pillow cleaning device be near rolling pillow, support to be housed, support is fixed on the strut by screw, and cleaning brush and adjustment screw are housed on support, cleaning brush with roll the pillow outer round surface contact.

Right wallboard and left wallboard fixing hole spacing are 740～840mm, and printing cylinder effectively prints over glaze to being of a size of 550～650mm.

The width dimensions that the outer terminal number of impression cylinder plays second group of grippers sheet and bite-block is widened 10～16mm, and the spacing of the second group of two groups of grippers in outer end, the impression cylinder left and right sides is 388～400mm.

The beneficial effects of the utility model: the utility model adopts said structure, traditional offset press first unit and second unit are separated, second unit is made the standard press group, because the wallboard end face in the standard press group is shaped on connecting hole, the standard press group is connected by the connecting hole on the wallboard end face with another standard press group, one of them standard unit is connected with paper supply printing unit, another standard press group is connected with collection printing unit, the utility model both can keep printing unit arrangement mode in the prior art, transportation is convenient in dismounting flexibly again, install and maintenance; Interim strippers is installed in the collection dolly top of collection printing unit, therefore changing the collection dolly does not need to shut down, printed sheet drops on the interim strippers, changed and extracted interim strippers behind the collection dolly out and continue printing, both can keep collection function of the prior art, again can be in that number to be printed be big when needing to change the collection dolly, do not shut down and change the collection dolly, printing can not cause printing ink imbalance continuously, does not produce useless opening, thereby improves printing efficiency; As required the second group of grippers sheet and the bite-block width dimensions of impression cylinder outer end are widened 10～16mm, make spacing between the second group of two groups of grippers in outer end, the impression cylinder left and right sides by original 368mm, be increased to 388～400mm, both can keep printing paper feed scope of the prior art, can increase again and grab the paper width, when making the magnanimous octavo 440 * 305mm paper of printing, two ends have only the wide trimming of 20～26mm can't hold paper in the month, can not cause paper-tear picture, reduce the paper feed fault rate; At the pillow place of rolling of transfer platen, plate cylinder the adjustable cleaning brush of elasticity is installed in addition, when unit turns round, plate cylinder and transfer platen are rolled pillow cleans automatically, avoid shutting down artificial cleaning the in back and roll the danger that pillow easily causes personal injury, be not easy to produce that to roll pillow dirty, improve plate cylinder and transfer platen service life; The base wallboard fixing hole spacing of printing unit is 740～840mm, printing cylinder (comprising impression cylinder, transfer platen, plate cylinder, transfer roller) effectively prints over glaze to being of a size of 550～650mm simultaneously, the magnanimous six open-width faces of 520 * 370mm had both been can be used for printing, can print positive four open-width faces again, use the paper web face to be increased to 560 * 400mm.
