2020 target: the system is successfully developed, and the demonstration line is put into trial operation to realize the computer monitoring and automatic operation of the whole process of Conghua feed, feeding, dyeing, dehydration, drying and material pfer.

3 CNC super large flower rotary screen printing machine

Meaning and content: the maximum print width of the traditional rotary screen printing machine is 1018 mm, while the commonly used flower printing is only 640 millimeters.

In order to meet the requirements of high efficiency printing of large-size patterns in home textiles and other industries, it is necessary to develop super large flower rotary screen printing machine.

During the "12th Five-Year" period, the technology of rotary screen printing has developed rapidly, which laid a good foundation for the detection and control of the flower precision of the super large flower rotary screen printing machine.

Under the premise of ensuring the accuracy of printing, the printing of super large flowers will greatly improve the printing efficiency of household textiles and reduce the labor intensity of operators.

Key technology: R & D and manufacture of super large printing circular screen, with 2412 millimeters back, 3000 mm above the door width, 60 mesh above the round mesh, CNC system for the printing machine of super large print, the design and development of the super large printing unit, and the development of the super large flower net system.

2020 target: prototype development, R & D of super large flower roundabout network, complete the test.

4 full width fixed nozzle for textiles

High speed digital inkjet printing technology and equipment

Significance and content: the inkjet printing machine with homemade reciprocating sprinkler has been successfully applied for many years, but the low printing speed has become a bottleneck that hinders the application of this machine to large-scale industrial applications.

The high speed digital inkjet printing technology and equipment for the development of full width fixed nozzle can increase the printing speed by several times to several dozens times while retaining the advantages of inkjet printing.

The equipment adopts full width fixed nozzle, printing speed is more than 40 meters / minute, 4 to 8 color position, width 1.6 to 2 meters, resolution 360dpi above, conduction belt cloth.

The key technology is the research and development of RIP software, that is, grating image processing software; the research of whole machine drive and control technology; the development of feeder device; the development of ink supply (ink making) technology and its system.

2020 target: complete prototype development and testing.

5 numerical control intermittent high temperature gas-liquid dyeing machine

Meaning and content: the machine developed on the basis of air flow dyeing machine, maintained the low bath ratio of air flow dyeing machine, but the installed capacity of fan motor was reduced by about 50%.

The machine adopts the structure of air flow nozzles and dye nozzles separately, O shaped cylinder block.

The fabric is run by airflow and run independently.

The energy consumption of the model for air traction is obviously reduced. According to the requirements of dyeing process, there are many combinations of gas and liquid, and the dyeing process has better adaptability.

The research and development of this type of machine is of great significance to the popularization and application of low bath ratio intermittent dyeing machine, and the energy saving effect is remarkable.

Key technologies: design and development of airflow and dye nozzle; research of air circulation system, design and development of traction fan; research and design of dye circulation system; design of cloth roller; research and design development of numerical control system.

2020 target: complete the test and put into production.

6 development and industrialization of electromagnetic induction heating vapor-liquid equilibrium hot rollers

Meaning and content: the electromagnetic induction hot roller is based on the principle of electromagnetic induction heating, so that the liquid in the metal sandwich rollers can be heated rapidly, and the vapor-liquid equilibrium can be achieved in a short time.

The latent heat of vaporization is used to release heat so as to ensure the uniform surface temperature of the roller body.

The special groove of the inner wall of the heat roller cavity is researched and designed, and the heat pipe heat pfer technology is creatively applied to the heat medium pmission structure of the device.
