Abstract

The invention discloses a centralized heating device of a printing machine. The centralized heating device comprises a hot blast stove body, a connecting air hose, an air supply fan and a heating pipeline, and further comprises a plurality of printing machine color cells, wherein the hot blast stove body, the connecting air hose, the air supply fan and the heating pipeline are fixedly connected in sequence; each printing machine color cell comprises a printing machine drying oven; each printing machine drying oven is connected with a drying oven air blower; each drying oven air blower communicates with the heating pipeline; a temperature control air valve is arranged at the joint of each drying oven air blower and the heating pipeline; and a temperature sensor is arranged on the heating pipeline. The centralized heating device has the advantage that the problem that the hot air temperature is unstable in the prior art can be solved.

Description

technical field [0001] The invention belongs to the technical field of printing and packaging equipment, and relates to a centralized heating device for printing machines. Background technique [0002] Heating and hot air system is an important part of printing and packaging machinery and equipment. Printed matter needs to be dried after printing. The traditional hot air for drying printed matter comes from electric heating air, steam heat exchanger heating air, heat transfer oil heat exchanger heating air, etc. Electric heating consumes a lot of energy; steam heating and heat-conducting oil heating require coal-fired boilers or gas-fired boilers to heat water and heat-conducting oil, and then heat the air through heat exchangers. Among them, coal-fired boilers are very polluting, and gas-fired boilers have low thermal energy utilization, which increases the production cost. The existing central heating device for natural gas hot blast stove has unstable hot air temperatur...
