Abstract
The utility model relates to an intaglio printing machine technical field can make the pneumatic top between each colour group not influence each other, simple structure moreover, convenient to use. The technical purpose of the utility model is realized like this: the utility model provides a gravure press's version roller top gas circuit structure, includes main trachea and many branch road trachea of drawing forth from main trachea, and the cylinder of the pneumatic top of a look group is connected respectively to every branch road trachea, and main trachea front end is equipped with total pneumatic valve, its characterized in that: and the branch air pipes are provided with manual air valves for switching on or off air flow.
Description
Technical Field
The utility model belongs to the technical field of the gravure press technique and specifically relates to a version roller top gas circuit structure of gravure press.
Background
The plate roller of the gravure printing machine is provided with concave holes at two ends of the axis or is provided with through holes along the axis, and the positioning is realized by pressing the holes at the two ends by a pneumatic top head. In a current production line, the tops of printing rollers of a plurality of gravure press color groups are supplied with air by a main air pipe, as shown in fig. 1, a main air pipe 2 is provided with a main air valve 1, and a plurality of branch air pipes 3 are led out from the main air pipe and are respectively connected to an air cylinder 4 of the pneumatic top of each printing roller. The drawbacks of this gas supply structure are: when one color group is stopped to replace or maintain the printing roller, the operation can be carried out only by closing the master air valve, and other color groups which do not need to be stopped also need to be stopped after the master air valve is closed, so that the interference to the production is great, the production efficiency is influenced, and the improvement is still needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming not enough among the above-mentioned background art, provide a gravure press's version roller top gas circuit structure, can make the pneumatic top between each colour group not influence each other, simple structure, convenient to use moreover.
The technical purpose of the utility model is realized like this:
the utility model provides a gravure press's version roller top gas circuit structure, includes main trachea and many branch road trachea of drawing forth from main trachea, and the cylinder of the pneumatic top of a look group is connected respectively to every branch road trachea, and main trachea front end is equipped with total pneumatic valve, its characterized in that: and the branch air pipes are provided with manual air valves for switching on or off air flow.
Preferably, the branch air pipe is further provided with a one-way valve, and the one-way valve is positioned between the manual air valve and the main air pipe.
Compared with the prior art, the utility model has the following advantage: the utility model discloses be provided with manual valve respectively on every branch road trachea, can open alone or close the cylinder of the top of a colour set, the setting of check valve further makes each other not influence between the colour set, overall structure is simple, convenient to use.
Drawings
Fig. 1 is a schematic view of a conventional piping structure.
Fig. 2 is a schematic diagram of the pipeline structure of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings.
As shown in fig. 2, a roller top air passage structure of an intaglio printing press comprises a main air pipe 2 and a plurality of branch air pipes 3 led out from the main air pipe, wherein each branch air pipe is respectively connected with an air cylinder 4 of a pneumatic top of a color group, and a main air valve 1 is arranged at the front end of the main air pipe. And the branch air pipes are provided with manual air valves 6 for switching on or off air flow. And the branch air pipe is also provided with a one-way valve 5 which is positioned between the manual air valve and the main air pipe.
The utility model discloses a theory of operation is:
under normal conditions, the main air valve and all the manual air valves are all opened, the top heads of all the color groups are all ejected out, and the printing roller is positioned. When the printing roller corresponding to a certain branch needs to be replaced, the manual air valve of the branch is manually closed, the air cylinder loses air pressure, and a worker can detach the printing roller for replacement. And after the replacement is finished, opening the manual air valve to supply air, and repositioning the printing roller. When all units need to be shut down for maintenance, the main air valve is closed, and all branch air pipes do not supply air.
The above description is only a preferred embodiment of the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
Claims (2)
1. The utility model provides a gravure press's version roller top gas circuit structure, includes many branch road trachea (3) of drawing forth on main trachea (2) and the main trachea of follow, cylinder (4) of the pneumatic top of a color space group are connected respectively to every branch road trachea, and main trachea front end is equipped with air valve (1), its characterized in that: and manual air valves (6) for switching on or off air flow are arranged on the branch air pipes.
2. The air passage structure of the roller top of the intaglio printing press according to claim 1, characterized in that: the branch air pipe is also provided with a one-way valve (5) which is positioned between the manual air valve and the main air pipe.
