Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing:

[0009] As shown in the accompanying drawings, the numerically controlled energy-saving drying device with fixed temperature and air volume for film printing includes a compressor 1 , a condenser 2 , an expansion valve 3 , a first-stage evaporator 4 and a second-stage evaporator 5 . The shell is divided into an air inlet chamber and an air outlet chamber, and a differential pressure feedback detection device 8 is connected to the oven of the film printing machine. There is an air inlet channel 6 on the air inlet chamber, and an air outlet channel 7 on the air outlet chamber. And the air outlet cavity is connected with the inlet and outlet of the film printing machine oven. There is an air outlet door and an induced draft fan in the air outlet channel 7. An air circulation system is formed by the air inlet cavity and the air outlet cavity. Fresh air passes through the air inle...

Abstract

The invention discloses a temperature and air-volume constant value numerical control energy-saving drying device for thin-film printing. The temperature and air-volume constant value numerical control energy-saving drying device for thin-film printing mainly solves the problems that an existing drying device is high in energy consumption, high in drying cost and low in degree of automation. The temperature and air-volume constant value numerical control energy-saving drying device for thin-film printing is characterized in that a draught fan, a second-stage evaporator (5), a condenser (2) and an electric heater are connected into an air inlet channel (6), a first-stage evaporator (4) is connected to an air outlet channel (7) in the shell, an outlet of a compressor (1) is connected with the condenser (2), the first-stage evaporator (4) and the second-stage evaporator (5) in series, an outlet of the second-stage evaporator (5) is communicated with an outlet of the compressor (1), a heat supply temperature detection device and a heat supply air-volume detection device connected with a controller are arranged on the air inlet channel (6), and an air outlet temperature detection device connected with the controller is arranged on an air outlet (8). The temperature and air-volume constant value numerical control energy-saving drying device for thin-film printing has the advantages of being low in energy consumption, low in drying cost and high in degree of automation.

Description

technical field [0001] The invention relates to a drying device, in particular to a digitally controlled energy-saving drying device with fixed temperature and air volume for film printing. Background technique [0002] In the field of film printing, after the ink is printed on the film, it needs to be dried quickly with a drying device. The drying device uses a fan to blow the heat generated by the electric heater into the oven to dry the ink on the surface of the film. However, due to structural reasons, the existing drying device has the problems of high energy consumption, high drying cost, and low degree of automation, which affect the cost of film printing and processing. Contents of the invention [0003] In order to solve the problems of high energy consumption, high drying cost and low degree of automation of existing drying devices. The invention provides a digitally controlled energy-saving drying device with constant temperature and air volume for film printin...
