Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, and particularly relates to a heat dissipation device for a heat transfer digital printing machine. Background Technique

[0002] The heat transfer digital printing machine is mainly used to transfer the pattern printed on paper to the fabric;

[0003] At present, in the polyester-ammonia heat transfer printing process, the pattern color on the paper is transferred to the fabric in contact with it through a high-temperature (210 - 230 °C) pressure device to complete the printing action. However, the fabric still has a relatively high temperature after passing through the roller (usually natural cooling and heat dissipation), which leads to the risk of color migration and color sublimation of the dye. At this time, stacking or coiling the fabric may cause color staining, and the darker the color and the more fabric hair, the greater the risk of color staining, resulting in fabric defects and seriously affecting the quality and unable to meet the customer's requirements.

[0004] In view of this, the utility model provides a heat dissipation device for a heat transfer digital printing machine, so that when the fabric is printed, rapid heat dissipation on its surface can be realized to reduce the generation of color migration and color sublimation and improve the yield.

[0007] As a preferred heat dissipation device for a heat transfer digital printing machine of the utility model, the fabric conveying device also has a workbench and a conveyor belt, the workbench and the conveyor belt are both arranged between the frame body one and the frame body two, and the workbench is located above the conveyor belt.

[0008] As a preferred heat dissipation device for a heat transfer digital printing machine of the utility model, the axial flow fan is located between the workbench and the conveyor belt.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4

[0021] , the utility model relates to a heat dissipation device for a thermal transfer digital printing machine, which includes a main body 1 of the thermal transfer digital printing machine and a fabric conveying device 2 connected to one side of the main body 1 of the thermal transfer digital printing machine. The fabric conveying device 2 has two symmetrically arranged frame bodies 21 and 22, and also has a workbench 23 and a conveyor belt 24. Both the workbench 23 and the conveyor belt 24 are arranged between the frame body 21 and the frame body 22, and the workbench 23 is located above the conveyor belt 24. A connecting frame 3 is arranged between the frame body 21 and the frame body 22, and an axial flow fan 4 is installed on the connecting frame 3. The axial flow fan 4 is located between the workbench 23 and the conveyor belt 24;

[0022] During use, first, the fabric 7 and the printing paper are respectively loaded on the material rollers (not marked in the figure) and paper rollers (not marked in the figure) on the fabric conveying device 2. After the installed fabric 7 and the printing paper are attached, they are laid on the workbench 23, extended onto the printing roller in the main body 1 of the thermal transfer digital printing machine and moved out to the surface of the conveyor belt 24. After the outgoing end is connected to a winding device (not marked in the figure), the main body 1 of the thermal transfer digital printing machine is started, so that the pattern on the printing paper is transferred to the fabric 7 and sent out by the conveyor belt 24. Under the action of the axial flow fan 4, the cold air blown by the axial flow fan 4 can continuously blow to the surface of the fabric 7, so as to quickly dissipate the heat on the surface of the fabric 7, reduce the temperature, effectively reduce the generation of color migration and color sublimation on the surface of the fabric 7, and improve the yield.

[0023] As a further improvement, in order to further reduce the temperature on the surface of the fabric 7, a semiconductor refrigeration sheet 5 can also be installed at the fabric output end of the fabric conveying device 2. The fabric 7 moved out from the conveyor belt 24 is attached to the refrigerating surface of the semiconductor refrigeration sheet 5 and connected to the winding device. Before the fabric 7 is continuously output and wound, the semiconductor refrigeration sheet 5 can cool the fabric 7 well;

[0024] At the same time, in order to ensure the good and stable operation of the semiconductor refrigeration sheet 5 and the refrigeration efficiency, a heat sink 6 is installed on the heating surface of the semiconductor refrigeration sheet 5 and attached thereto. The heat sink 6 can accelerate the heat dissipation of the hot surface temperature of the semiconductor refrigeration sheet 5, thereby reducing the influence on the refrigeration of the cold surface and realizing the good, stable and efficient operation of the refrigerating surface of the semiconductor refrigeration sheet 5.
