Embodiment 1

[0014] Ultrasonic humidifier wetting device for cold transfer printing machine.

[0015] As shown in Figure 1, a wetting device is installed on the new cold transfer printing machine. There is a spray port 1 in front of the roll transfer device of the cold transfer printing machine, the spray port is a fully open spray port, fixed on the frame, the spray direction of the spray port 1 is aligned with the upper roller 4, and the upper transfer printing paper 3 advances direction of the pattern face. The spray port is equipped with a baffle, which can adjust the width of the spray port. The maximum effective spray width is 1.6m, which is the same as the effective width of the upper roll of 1.6m. The rear part of the spray port 1 is connected with the humidifier and the fan through the pipeline. The humidifier is the humidifying part of the industrial ultrasonic humidification sprayer, and the humidification capacity reaches 2kg / h, and the fan uses an axial flow fan. When the co...

Embodiment 2

[0017] Centrifugal humidifier wetting device for cold transfer printing machine.

[0018] As shown in Figure 1, a wetting device is installed on the new cold transfer printing machine. There is a spray port 1 in front of the roll transfer device of the cold transfer printing machine, and the spray port of the nozzle is installed on the mouth surface, which is fixed on the frame, and the spray direction of the spray port 1 is aligned with the transfer printing paper 3 on the upper roller 4 The pattern face for the forward direction. The spray port is equipped with a baffle, which can adjust the width of the spray port. The maximum effective spray width is 1.6m, which is the same as the effective width of the upper roll of 1.6m. The rear part of the spray port 1 is connected with a humidifier and a fan through a pipeline. The humidifier is a centrifugal humidifier with a humidification capacity of about 3kg / h, and the fan is a centrifugal fan. When the cold transfer printing m...

Embodiment 3

[0020] Evaporative humidifier wetting device for cold transfer printing machine.

[0021]As shown in Figure 1, a wetting device is installed on the new cold transfer printing machine. There is a spray port 1 before the roller transfer printing device of the cold transfer printing machine, which is fixed on the frame, and the spray direction of the spray port 1 is aligned with the pattern surface of the transfer printing paper 3 advancing direction on the upper roller 4 . The spray port is equipped with a baffle, which can adjust the width of the spray port. The maximum effective spray width is 1.8m, which is the same as the effective width of the upper roll of 1.8m. The rear part of the spray port 1 is connected to the humidifier and the fan with a hard PVC pipe. The humidifier is a JJL-004A evaporative humidifier with a humidification capacity of 2-5kg / h, and a humidity sensor is used to control the humidification capacity. When the cold transfer printing machine is working,...

Abstract

The invention relates to a dampening method and relative device for cold transferring stamp, wherein before cold transferring stamping paper and transferring upper and main rollers, the invention uses dampening atomization method to pre-dampen the pattern face along the moving direction of the transfer damping paper on the upper roller. The dampening device comprises an atomizing opening at the front of the roller transfer device, while the back of the atomization opening via a tube is connected to a dampening atomizer or connected with a dampener and a fan to form a dampening device of the cold transfer stamping device. The inventive dampening method can control the water content of dampened paper between 2% and 30%. The invention method and device can dampen the surface color paste of stamping paper to improve transfer rate, color rate and resolution.

Description

technical field [0001] The invention relates to the printing and dyeing engineering of the textile industry, in particular to a wetting method of cold transfer printing and its device Background technique [0002] Traditional printing and dyeing methods will produce a large amount of waste water and waste gas, seriously polluting the environment, and in the production process, due to the need for a large amount of steam and heat energy, energy consumption is also increasing. In order to protect the environment and reduce energy consumption, many countries are researching new dyeing and finishing processes that do not use water or use less water, which results in transfer printing, a dry printing process. Transfer printing is to print the dye originally printed on the fabric on the transfer paper, and then transfer it to the cloth by mechanical and chemical methods. The dry printing process of transfer printing paper was initially used on some synthetic fiber fabrics, but in...
