[0012] Beneficial effects of the utility model:

[0013] (1) In the utility model, a pressing plate and a pressing block are arranged so that the pressing plate and the pressing block can be scraped and ironed again after the pressing is performed once, so as to avoid the problem that the fabric is easily stamped and the printing is incomplete after the pressing is performed once. The fabric to be pressed is placed on the workbench, and the pressing cylinder is started to press the entire pressing plate down through the transmission rod. After pressing onto the transfer paper on the upper end of the fabric, the printing on the transfer paper is pressed onto the fabric through the heat emitted by the electric heating element inside the pressing plate. After the pressing is performed once, the pressing block cylinder at the upper end of the pressing plate will press the pressing block at the lower end down through the piston rod, and the pressing block protrudes out of the pressing plate through the pressing block groove. After the pressing block protrudes out of the pressing plate, the electric slider will slide to the left through the bracket slide, and the support rod will drive the pressing block at the lower end, and the piston rod at the upper end of the pressing block will slide smoothly to the left through the sliding groove. While sliding, the pressing block will use the heat of the internal electric heating element to scrape and iron the printed part of the fabric at the lower end for the second time, so as to remove the stamping produced by the pressing once and stamp the printing more firmly on the fabric, and the problem of jagged edges of the printing will not occur.

[0014] (2) In the utility model, a transfer paper winding assembly and a transfer paper unwinding assembly are provided to realize automatic removal of the transfer paper after hot stamping and printing. A roll of printed transfer paper is placed on the upper end of the transfer paper unwinding assembly, and one side of the printed transfer paper is pulled out and placed on the winding rod at the upper end of the transfer paper winding assembly. The upper end of the fabric on the workbench will have the printed pattern that currently needs to be hot stamped. After the entire hot stamping process, the fabric is cooled by the cooling assembly, and the winding motor of the transfer paper winding device will start to drive the winding rod to rotate to rewind the hot stamped transfer paper. The rotation of the winding rod will also drive the transfer paper unwinding device to rotate to unwind the printed transfer paper, and unwind the printed transfer paper that has not been hot stamped to the upper end of the fabric that needs to be hot stamped and printed, and repeat this process in sequence. This can effectively reduce labor and improve production efficiency.

[0015] (3) In the utility model, by providing a cooling component and a refrigerant net, the fabric on the workbench that has been pressed and ironed can be quickly cooled, which is convenient for cold tearing and removing the transfer paper. After the fabric is pressed and ironed, heat will be generated at the pressed part, which is not conducive to the cold tearing of the transfer paper. At this time, the fan motor at the lower end of the cooling component will start to work and drive the output shaft. The output shaft drives the fan blades to rotate at high speed to generate wind. The wind will pass through the refrigerant net at the upper end of the cooling component and blow to the lower end of the workbench. The liquid absorption core net in the center of the refrigerant net will absorb the refrigerant liquid poured into the liquid injection port. The heat of the pressed part of the fabric is absorbed completely, and it is quickly cooled, which is convenient for the subsequent rewinding and removing of the transfer paper. When the refrigerant net needs to be replaced, it only needs to be connected by sliding the upper sliders of the fixed seats on the left and right ends of the refrigerant net with the sliding rails on the left side of the lower end of the workbench to pull out the refrigerant net and replace the internal refrigerant core net. The operation process is simple, convenient and durable.

[0016] In summary, the device has the advantages of secondary scraping and ironing to ensure printing effect, reduce manual operation and improve work efficiency, and is simple and convenient to operate, and is particularly suitable for the technical field of thermal transfer machines.

The internal electric heating elements can heat the pressing plate 52 and the pressing block 5215 to perform pressing and ironing work.

[0033] Working process: first, place the fabric to be pressed and printed on the workbench 2, then place a whole roll of printed transfer paper on the transfer paper unwinding assembly 41, pull out one side of the printed transfer paper and place it on the reel-up rod 43 at the upper end of the transfer paper reel-up assembly 4, the upper end of the fabric on the workbench 2 will have the printed pattern that currently needs to be pressed, then the pressing cylinder 51 will start to press the entire pressing plate 52 down through the transmission rod, and after pressing onto the printed transfer paper on the upper end of the fabric, the heat emitted by the internal electric heating element of the pressing plate 52 will press the print on the printed transfer paper onto the fabric, and after one pressing, the pressing block cylinder 5214 at the upper end of the pressing plate 52 will be activated The plug rod presses down the pressing block 5215 at the lower end, and the pressing block 5215 protrudes out of the pressing plate 52 through the pressing block groove 53. After the pressing block 5215 protrudes out of the pressing plate 52, the electric slider 5212 will slide to the left through the bracket slide 521, and the support rod 5213 will drive the pressing block 5215 at the lower end, and the piston rod at the upper end of the pressing block 5215 will slide smoothly to the left through the sliding groove 531.

[0034] Secondly, after the entire pressing process, the pressed part of the fabric will generate heat, which is not conducive to the cold tearing of the transfer paper. Then the fan motor 34 at the lower end of the cooling component 3 will start to work and drive the output shaft. The output shaft drives the fan blades 33 to rotate at high speed to generate wind. The wind will pass through the refrigerant net 6 at the upper end of the cooling component 3 and blow to the lower end of the workbench 2. The liquid absorbent core net 63 at the center of the refrigerant net 6 will absorb the refrigerant liquid poured into the liquid injection port 621 and evenly distribute it throughout the liquid absorbent core net 63. When the wind passes through the liquid absorbent core net 63, it will become cold wind and be transmitted to the steel table through the evenly distributed through holes 211 on the middle transparent plate 21, so as to absorb the heat of the pressed part of the fabric and cool it quickly, which is convenient for the subsequent winding and lifting of the transfer paper.

After the pressed part of the fabric is cooled, the winding motor 44 of the transfer paper winding device 4 will start and drive the winding rod 43 to rotate to rewind the pressed transfer paper and cold-tear the transfer paper. The rotation of the winding rod 43 will also drive the transfer paper unwinding device 41 to rotate to unwind the printed transfer paper, and unwind the printed transfer paper that has not been pressed to the upper end of the fabric that needs to be pressed and printed, and repeat in sequence. It can effectively reduce labor and improve production efficiency.
