Description

Technical Field

[0001] The utility model belongs to the technical field of fabric printing, and particularly relates to a double-sided heat transfer printing machine. Background Art

[0002] Fabric, also known as textile, is a sheet material made by processing natural or synthetic fibers, spinning and interweaving yarns, knitting, or non-woven methods. It is an indispensable part of multiple fields such as clothing, home, decoration, industry, medical, military, engineering technology, etc. In the existing double-sided heat transfer printing machine, during the process of winding the fabric, the printed paper after heating is pressed on the fabric by the printing rollers on the upper and lower sides to achieve double-sided heat transfer printing of the fabric. However, in the actual use process, due to the different types and specifications of the processed fabrics, the printing rollers cannot well adapt to print fabrics of different thicknesses.

[0003] For example, the utility model with the publication number CN217099344U discloses a heat transfer printing machine, which includes a first transfer mechanism and two second transfer mechanisms respectively located on the upper and lower sides of the first transfer mechanism. The two second transfer mechanisms are located in the same vertical direction. The first transfer mechanism and the second transfer mechanisms are used to transport transfer paper or cloth. Both of the two second transfer mechanisms include printing rollers, and the rollers of the two printing rollers are in contact with the transfer paper or cloth transported on the first transfer mechanism. In the technical solution of this patent, through the combination of the printing rollers on the upper and lower sides, the transfer paper after heating during the winding process is pressed on the cloth during the collection process to achieve double-sided heat transfer printing of the fabric. However, in the actual use process, due to the different types and specifications of the processed fabrics, when performing double-sided heat transfer printing on some thinner or thicker fabrics, since the positions of the printing rollers are mostly fixed, the printing rollers cannot well adapt to print fabrics of different thicknesses.

[0023] As Figure 1 , 2 As shown in FIGS. 3, the printing module includes a first support 201 symmetrically arranged on the opposite inner side surfaces of the two side plates 103. Guide rails 202 are respectively arranged between two vertically adjacent first supports 201.

Printing rollers 204 are respectively rotatably arranged between two horizontally adjacent sliding seats 203. The two printing rollers 204 are cooperatively installed.

The ends of the connecting rods 208 far from the adjusting seats 207 are respectively rotatably connected to the adjacent sliding seats 203. An electric drive assembly for driving the adjusting seats 207 to move is further arranged between the side plates 103; the electric drive assembly includes a bidirectional lead screw 209 rotatably arranged between two horizontally adjacent second supports 205. The adjusting seats 207 are respectively threadedly connected to the adjacent bidirectional lead screws 209. Two motors 210 symmetrically distributed vertically are arranged on the opposite inner side surfaces of the two side plates 103. The output shafts of the motors 210 are respectively fixed to the adjacent bidirectional lead screws 209 through couplings.

[0024] As Figure 1 As shown, a control panel 301 is arranged on the front side of the side plate 103. The heating roller 112, the cooling assembly 114, the motor 115, the motor 116 and the motor 210 are all electrically connected to the control panel 301.

[0025] When heat transfer printing is required for fabric processing, the operator places the fabric unwinding roller between two fabric unwinding cylinders 105, slides the two fabric unwinding cylinders 105 to insert the fabric unwinding roller into the interior of the two fabric unwinding cylinders 105, and then uses an external tool to turn the bolts to install the fabric unwinding roller; places the fabric winding roller between two fabric winding cylinders 107, slides the two fabric winding cylinders 107 to insert the fabric winding roller into the interior of the two fabric winding cylinders 107, and then uses an external tool to turn the bolts to install the fabric winding roller; places the printing roll unwinding roller between two printing unwinding cylinders 109, slides the two printing unwinding cylinders 109 to insert the printing roll unwinding roller into the interior of the two printing unwinding cylinders 109, and then uses an external tool to turn the bolts to install the printing roll unwinding roller; places the printing roll winding roller between two printing winding cylinders 111, slides the two printing winding cylinders 111 to insert the printing roll winding roller into the interior of the two printing winding cylinders 111, and then uses an external tool to turn the bolts to install the printing roll winding roller, enabling quick installation and disassembly of each roller required in the processing; connects the fabric on the fabric unwinding roller to the fabric winding roller, passes the printing paper on the printing roll unwinding roller around the adjacent heating roller 112, then around the adjacent printing roller 204, and then around the heat-conducting cooling roller 113 and connects it to the printing roll winding roller to prepare for printing.

[0026] Through the control panel 301, the four motors three 210 are regulated to run synchronously, thereby causing the motors three 210 to drive the bidirectional lead screws 209 connected thereto to rotate respectively. Due to the threaded relationship between the bidirectional lead screws 209 and the adjusting seats 207, the adjusting seats 207 on the left and right sides move closer to each other. During the movement of the adjusting seats 207, rotations occur between the adjusting seats 207 and the connecting rods 208, and between the connecting rods 208 and the sliding seats 203. Thus, the adjusting seats 207 on the left and right sides drive the sliding seats 203 on the upper and lower sides to move closer to each other through the connecting rods 208, and then the distance between the upper and lower printing rollers 204 can be quickly and stably adjusted according to the thickness of the fabric to be printed, pressing the printing paper on the upper and lower sides onto the fabric.

[0027] The operation of the heating roller 112, the cooling assembly 114, the first motor 115 and the second motor 116 is controlled through the control panel 301, so that the heating roller 112 heats the printing paper in contact therewith, and the fabric passing through is quickly cooled by the cooling assemblies 114 on the upper and lower sides. The output shaft of the first motor 115 drives the second rotating cylinder 106 connected thereto to rotate, thereby driving the fabric winding roller to rotate. The output shaft of the second motor 116 drives the fourth rotating cylinder 110 connected thereto to rotate, thereby driving the printing roll winding roller to rotate. Thus, during the process of winding the printing paper on the printing roll winding roller from the printing roll unwinding roller and winding the fabric on the fabric winding roller from the fabric unwinding roller, the heating roller 112 heats the printing paper, the printing on the heated printing paper is transferred onto the fabric through the printing roller 204, and then the printed printing paper is cooled by the heat-conducting cooling roller 113, and the cooled fabric is quickly cooled by the cooling assemblies 114, realizing hot transfer printing of the upper mold on the fabric.

[0028] According to another embodiment of the present invention, as Figure 1 、 3 shown in FIG. 4, rubber pads are adhesively fixed to the lower surfaces of the supporting feet 102. During actual use, the rubber pads can increase the friction between the supporting feet 102 and the ground, thereby effectively preventing the frame 101 from moving easily.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
