Embodiment Construction

[0017] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0018] refer to Figure 1 to Figure 3 , the lithographic offset printing machine of the automatic operation of the present embodiment comprises a main frame 1 and an offset printing device 3 , a drying device 4 , and a material receiving device 5 which are sequentially passed by a tray 2 assembled on the main frame 1 , and the tray 2 is fixedly installed with flat substrate.

[0019] Continue to refer to figure 1 , the above-mentioned offset printing device 3 is used to perform positioning offset printing on the planar substrates in the trays 2 that pass sequentially. The above-mentioned offset printing device 3 includes a lifting table 31, an offset printing plate 32, and a stop trigger 33. When the tray 2 enters the offset printing device 3 to a designated position, the pulling stop trigger is triggered to stop the progress of the pallet 2. The tray ...

Abstract

The invention relates to an automatic operation lithographic offset press. The offset press comprises a main rack, an offset printing device, a drying device and a material receiving device, wherein atray assembled on the main rack sequentially passes through the offset printing device, the drying device and the material receiving device, a planar base material is fixedly arranged in the tray, the offset printing device is used for carrying out positioning offset printing on the planar base material in the tray passing through in sequence, the drying device comprises a shell, an ascending mechanism, a descending mechanism and an air exhaust mechanism, the ascending mechanism, the descending mechanism and the air exhaust mechanism are assembled in the shell, the utilization rate of the longitudinal space is increased in the mode that the drying device ascends and then descends the tray, and air flow in the shell is transverse due to the arrangement of an air inlet and the air exhaust mechanism of the drying device, so that the volatilization speed and the drying efficiency of a solvent are favorably improved, air entering from the air inlet is not prone to discharging from a feed port and a discharge port of the shell under negative pressure, and the use is more environment-friendly.

Description

technical field [0001] The invention relates to the field of offset printing machines, in particular to an offset printing machine used for automatic operation on the surface of shoe materials or other flat materials. Background technique [0002] Offset printing is a kind of lithographic printing. Simply speaking, offset printing is a printing method in which the graphics on the printing plate are transferred to the substrate by means of rubber (blanket). Offset printing performs single-color or multi-color overprinting multiple times, that is, when printing a printed matter, the graphics and texts of various colors on the printing plate are accurately superimposed on the same printed matter; and the dots of various colors are not deformed. Graphics and texts are not out of shape, and the color is gorgeous, full of three-dimensional effect. Offset printing is required to have a very high degree of registration, and the printed adhesive layer needs to be dried after each pr...
