Description
Technical field
The present invention 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 that printing is carried out at short notice is dry 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, have higher requirement to drying device, dry problem has become the bottleneck of restriction equipment to high speed, high accuracy future development.The many employings of the drying box air intake from the side of present stage, through once even wind, is then ejected into material film surface from single V-type nozzle, eventually pass 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 does not all pass through good air uniform device, further reduces the uniformity of hot wind flow in drying box; In addition, the nozzle air quantity of single V-type is little, wind speed is low, constrains printing drying efficiency.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and enter from back, return air, and wind speed is high, air quantity is large, drying efficiency is high for printing and the drying box of coating apparatus.
The present invention's adopted technical scheme that solves the 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 multiple nozzles of guide roller assembly, be located at the nozzle base sheet of casing front portion, 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 be connected with air inlet and the return air channel be connected with return air inlet, described multiple nozzle pitch fits are installed on nozzle base sheet, described nozzle comprises symmetrically arranged 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 invention has the advantages that: of the present invention for print and the drying box of coating apparatus from centre position, casing back air intake, be ejected into printing product surface through air intake passage from double V-shaped nozzle and carry out drying.Hot blast after drying is complete, discharges through the return air inlet of return air channel from casing back.This drying box owing to entering from back, return air, effectively solve the 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.Distance L between the two V nozzle of reasonable adjusting, makes speed during hot blast arrival guide roller surface be just maximum (as shown in Figure 8).This drying box significantly can improve the wind speed of hot blast, and the air quantity of adding two V nozzle is original twice, can improve the drying efficiency of drying box greatly.
