Abstract
An improved offset printing device comprises a casing and a printing mechanism in the casing, wherein, the printing mechanism comprises a plate cylinder, a blanket cylinder, and an impression cylinder, wherein, the plate cylinder rolling is contacted with the blanket cylinder in a rolling way, the blanket cylinder rolling is contacted with the impression cylinder in a rolling way. The utility model is characterized in that: one side of the blanket cylinder far away from the impression cylinder is provided with a detachable coating mechanism. The coating mechanism comprises a hopper, a coating roller and a box cutter knife, wherein, the lower end of the coating roller is arranged in the hopper, the left side of the coating roller is contacted with the blanket cylinder in a rolling way, the right side of the coating roller is contacted with box cutter knife. Compared with the prior art, the utility model has the advantages that: as the coating mechanism is arranged, the offset printing device not only has the printing function, but also has the function of coating and glazing, so that the cost of purchasing equipment by the enterprise is decreased greatly, and the user can install or disassemble the coating mechanism according to the requirements.
Description
Technical field
The utility model relates to a kind of printing equipment, more specifically to a kind of improved offset printing device that is used for offset printing.
Background technology
In offset printing process, often will use a plurality of offset printing devices and a plurality of coating glazing operation, but existing offset printing device does not possess coating glazing mechanism, its coating glazing operation adopts glazing equipment independently mostly or adopts the method for PS version glazing.
As Chinese patent literature CN2518681 " the protruding glue printing machine of a kind of monochrome ", the protruding glue printing machine of disclosed a kind of monochrome, comprise frame, paper advance mechanism, printing mechanism, transmission mechanism and paper collecting mechanism, printing mechanism comprises central cylinder, rubber cylinder and ink roller, transmission mechanism comprises motor, transmission line shaft and travelling gear, above-mentioned rubber cylinder, transmission line shaft and ink roller are arranged the periphery that is installed in central cylinder in order, the preceding half cycle of central cylinder is the forme face, second half is the impression face, and the girth of central cylinder is 2 times of the rubber cylinder girth.This printing machine is the protruding glue printing machine of small-sized monochrome, so its printing mechanism is the offset printing device of realizing offset printing, and the complicated offset printing process of great majority needs a plurality of offset printing devices and other transmission device to be formed by combining.
But the method for PS version glazing because the PS version is thinner, therefore can not play the better protect effect.Independently be coated with glazing equipment and use, need expend a large amount of funds.And because the typography of a lot of printing products needs multiple tracks coating glazing operation, for less enterprise, its economic capability is limited, is difficult to purchase many equipment that have coating glazing mechanism, and therefore existing offset printing device can't satisfy the demands.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of improved offset printing device is provided, and possesses the function of coating glazing, and the technical scheme of employing is as follows:
Improved offset printing device of the present utility model, comprise the printing mechanism in casing and the casing, printing mechanism comprises plate cylinder, blanket cylinder and impression cylinder from top to bottom successively, plate cylinder rolls with blanket cylinder and contacts, blanket cylinder rolls with impression cylinder and contacts, and it is characterized in that: described blanket cylinder is provided with dismountable coating mechanism away from a side of impression cylinder.
Described coating mechanism comprises hopper, applicator roll and box cutter, and the applicator roll lower end is positioned at hopper, rolls with blanket cylinder and contact in the left side of applicator roll, and the applicator roll right side contacts with box cutter.
The utility model beneficial effect against existing technologies is, owing to be provided with coating mechanism, so offset printing device not only possesses printing functionality, also possessed the function of coating glazing, can significantly reduce the cost of enterprise's purchase of equipment, and the user can install or pull down coating mechanism as required.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 is the structural representation of preferred embodiment offset printing production line shown in Figure 1.
The specific embodiment
As shown in Figure 1, in this preferred embodiment, improved offset printing device 1 comprises the printing mechanism in casing 101 and the casing 101.
Printing mechanism comprises plate cylinder 102, blanket cylinder 103 and impression cylinder 104 from top to bottom successively.Plate cylinder 102 rolls with blanket cylinder 103 and contacts, blanket cylinder 103 rolls with impression cylinder 104 and contacts, described blanket cylinder 103 is provided with dismountable coating mechanism away from a side of impression cylinder 104, coating mechanism comprises hopper 105, applicator roll 106 and box cutter 107, applicator roll 106 lower ends are positioned at hopper 105, roll with blanket cylinder 103 and contact in applicator roll 106 left sides, applicator roll 106 right sides contact with box cutter 107.
As shown in Figure 2,, an offset printing production line, comprise not improved offset printing device 2, improved offset printing device 1, not improved offset printing device 3 and material collecting device 4 successively, link to each other by bindiny mechanism 5 between not improved offset printing device 2 and the improved offset printing device 1, link to each other by bindiny mechanism 6 between not improved offset printing device 3 and the improved offset printing device 1.
Because improved offset printing device 1 is provided with coating mechanism,, just do not need to increase an apparatus for coating if therefore have only coating glazing operation one.
The above coating glazing operation of twice or twice then can reduce by an apparatus for coating if desired, has therefore reduced cost.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Be all equivalents of being done according to claim scope of the present utility model, be the utility model claim scope and cover.
