Abstract
The invention provides a three-point suspension type web press adopting the rubber cylinder secondary pressing technology. The web press solves the problem of large paper waste of the existing web press caused by primary pressing technology. The three-point suspension type web press comprises a plate cylinder, a rubber cylinder and an impression cylinder. The rubber cylinder is arranged between the plate cylinder and the impression cylinder in non-contact mode. A cam mechanism enabling the rubber cylinder to be pressed towards the plate cylinder or the impression cylinder is respectively arranged at two ends of the rubber cylinder. By means of the web press, one-time pressing of the three cylinders can be broken up into two independent processes, so that presswork quality of the press can be ensured, and paper waste caused by adjustment can be avoided. The web press improves production efficiency and saves production cost.
Description
Technical field
The present invention relates to the printing equipment technical field, particularly a kind of web press of 3 floated blanket cylinder secondary combined pressures.
Background technology
Offset press in the application of current society more and more widely, it is to utilize the principle of " ink is immiscible " to realize printing.Its crucial printing unit is made of: plate cylinder, blanket cylinder and impression cylinder, these three cylinders are (accompanying drawings 1) separated from each other when not working, plate cylinder is by middle medium-blanket cylinder during work, under the pressure of impression cylinder the pattern on the forme is being imprinted on (accompanying drawing 2) on the article of undertaking the printing of.Will reach one " ink-water balance point " at forme and rubber before printing, existing 3 floated sheet-fed press often adopt the mode of " dry run, but paper " to realize.In web press, because paper is continuous, if adopt a combined pressure technology will cause that paper and machine together turn round after the combined pressure, and the pattern on forme and the rubber does not also reach print request, cause a large amount of wastes of paper, both reduce production efficiency, increased production cost again, and increased difficulty for the follow-up work of printing.
Summary of the invention
The invention provides a kind of web press of 3 floated blanket cylinder secondary combined pressures, solved existing web press owing to adopt a combined pressure technology to cause a large amount of problems of wasting of paper.
Technical scheme of the present invention is achieved in that a kind of web press of 3 floated blanket cylinder secondary combined pressures, comprise plate cylinder, blanket cylinder and impression cylinder, blanket cylinder is non-contacting to be arranged between plate cylinder and the impression cylinder, and the blanket cylinder two ends are provided with and make blanket cylinder to the cam mechanism of plate cylinder or impression cylinder combined pressure.
Wherein, preferably, described cam mechanism comprises cylinder, rocking arm, connecting rod and cylindrical cam, and the end of cylinder piston is connected with rocking arm one end, and the other end of rocking arm is connected with an end of connecting rod, and the slide block of the connecting rod other end slides in the cam path of cylindrical cam.
Wherein, preferably, described cylinder is double stroke cylinder.
The present invention can be decomposed into the disposable combined pressure of three cylinders two fully independently processes, can either guarantee the quality of this machine printed matter, has avoided the paper waste that brings because of debugging again, enhances productivity, and saves production cost.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the cylinder schematic diagram of the web press off working state of background technology;
Fig. 2 is the cylinder schematic diagram of the web press duty of background technology;
Cylinder schematic diagram when Fig. 3 is combined pressure of web press of the present invention;
Cylinder schematic diagram when Fig. 4 is web press secondary combined pressure of the present invention;
Fig. 5 is the structural representation of web press cam mechanism of the present invention.
Among the figure, 1. plate cylinder, 2. blanket cylinder, 3. impression cylinder, 4. cylinder, 5. rocking arm, 6. connecting rod, 7. cylindrical cam
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As Fig. 3, Fig. 4 and shown in Figure 5, present embodiment provides a kind of web press of 3 floated blanket cylinder secondary combined pressures, comprise plate cylinder 1, blanket cylinder 2 and impression cylinder 3, blanket cylinder 2 non-contacting being arranged between plate cylinder 1 and the impression cylinder 3, blanket cylinder 2 two ends are provided with and make blanket cylinder 2 to the cam mechanism of plate cylinder 1 or impression cylinder 3 combined pressures.
Wherein, cam mechanism comprises double stroke cylinder 4, Rocker arm 5, connecting rod 6 and cylindrical cam 7, the end of cylinder 4 pistons is connected with Rocker arm 5 one end, and the other end of Rocker arm 5 is connected with an end of connecting rod 6, and the slide block of connecting rod 6 other ends slides in the cam path of cylindrical cam 7.The middle part of rocking arm arranges a fulcrum, is that fixing point rotates with the fulcrum.Double stroke cylinder can make cylindrical cam rotate along different directions, thereby blanket cylinder is moved to different directions, realizes the secondary combined pressure of the cylinder of web press.
The present invention is by the improvement to printing machine combined pressure control cam, and cooperates double stroke cylinder to realize between plate cylinder and the blanket cylinder twice combined pressure process between blanket cylinder and the impression cylinder respectively.In off working state, plate cylinder, blanket cylinder and impression cylinder are noncontact each other, after (double stroke cylinder moves for the first time) combined pressure (accompanying drawing 3), plate cylinder and blanket cylinder force together, and the pattern on the forme is passed to blanket cylinder for the first time.And at this moment impression cylinder and blanket cylinder separate, and middle paper can be halted state.This just can guarantee that plate cylinder and blanket cylinder have sufficient time to reach typographic " ink-water balance ".By the time after the pattern on the blanket cylinder reached print request, after (double stroke cylinder moves for the second time) combined pressure (accompanying drawing 4), blanket cylinder and impression cylinder forced together for the second time, and paper turns round simultaneously and realizes printing.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
