Description
Technical field
The utility model relates to printer field, particularly a kind of for printing and the drying box of coating apparatus.
Background technology
Dry link is one of core link on intaglio printing and coating apparatus, its objective is printing is dried at short notice fast, and wherein the drying efficiency of the structural parameters printing product of drying box and uniformity have great impact.Along with improving constantly of device rate, drying device to be had higher requirement, dry problem has become restriction equipment to bottleneck high-speed, high accuracy future development.The drying box of present stage adopts air intake from the side more, through even wind once, then from single V-type nozzle ejection to material film surface, finally by cross once even wind from the side exhaust outlet discharge.This drying box owing to entering from the side, return air, cause printing left and right sides rate of drying inconsistent, uniform drying is not good enough; Secondly, the process of air intake and return air is not all passed through good air uniform device, has further reduced the mobile uniformity of hot blast in drying box; In addition, the nozzle air quantity of single V-type is little, wind speed is low, has restricted printing drying efficiency.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of and enter from back, return air, wind speed is high, air quantity is large, drying efficiency is high for printing and the drying box of coating apparatus.
The technical scheme in the invention for solving the above technical problem is: a kind of for printing and the drying box of coating apparatus, comprise casing, be installed on the box frame of box house, be located at the cover plate at casing back, be right against a plurality of nozzles of guide roller assembly, be located at the nozzle base sheet of casing front portion, on the cover plate at described casing back, there are respectively air inlet and at least one return air inlet, and in described casing, be respectively equipped with the air intake passage being connected with air inlet and the return air channel being connected with return air inlet, described a plurality of nozzles interval fit is installed on nozzle base sheet, described nozzle comprises symmetrically arranged the first V-type nozzle and the second V-type nozzle, and the distance between the mouth mouth of the first described V-type nozzle and the mouth mouth of the second V-type nozzle is L.
Compared with prior art, the utility model has the advantage of: of the present invention for print and the drying box of coating apparatus from centre position, casing back air intake, through air intake passage, from double V-shaped nozzle ejection, to printing product surface, be dried.Hot blast after being dried, discharges from the return air inlet at casing back through return air channel.This drying box owing to entering from back, return air, effectively solved the even phenomenon of printing left and right sides uneven drying; In addition, adopt double V-shaped nozzle, air-flow overlaps mutually after O point, and its speed is the momentum sum of two strands of jets.Rationally regulate the distance L between two V nozzles, the speed while making hot blast arrive guide roller surface is just maximum (as shown in Figure 8).This drying box can significantly improve the wind speed of hot blast, and the air quantity of adding two V nozzles is original twices, can improve greatly the drying efficiency of drying box.
