It should be noted that the description herein of the positional relationships of the various components, such as component A being located above component B, is based on the relative positions of the components in the illustrations and is not intended to limit the actual positional relationships of the components. Example 1

[0026] See also Figures 1-6 , Figure 1 The overall structure of a flattening device for a thermal transfer film according to Example 1 is shown. As shown, the flattening device for a thermal transfer film according to Example 1 comprises a base plate 1, on top of which are mounted, from left to right, a first mounting frame 7, a rolling mechanism 8, and a second mounting frame 9.

[0027] The first mounting bracket 7 is penetrated by a first blowing mechanism 10 and a second blowing mechanism 11 which are symmetrical with each other. The first blowing mechanism 10 and the second blowing mechanism 11 are respectively located above and below the thermal transfer film, and the airflows blown out by the first blowing mechanism 10 and the second blowing mechanism 11 are directed toward the two side edges of the thermal transfer film. A through slot 12 is provided in the middle of the first mounting bracket 7 for the thermal transfer film to pass through. By setting the first mounting bracket 7, the first blowing mechanism 10 and the second blowing mechanism 11, the first blowing mechanism 10 and the second blowing mechanism 11 are connected to an external air source when in use, and then the first blowing mechanism 10 and the second blowing mechanism 11 located above and below the thermal transfer film are used to blow air toward the two side edges of the thermal transfer film at the same time, so that the inward curled part of the edge of the thermal transfer film is blown flat, thereby preventing the curled part of the edge of the thermal transfer film from being directly crushed by the crushing mechanism 8, and preventing the curled part of the edge of the thermal transfer film from overlapping with the main part of the thermal transfer film.

[0028] A first antistatic brush 13 and a second antistatic brush 14 are symmetrically installed on the inner side of the second mounting frame 9. A gap is provided between the first antistatic brush 13 and the second antistatic brush 14 for the thermal transfer film to pass through. The first antistatic brush 13 and the second antistatic brush 14 are commonly connected to a grounding wire 15. By arranging the second mounting frame 9, the first antistatic brush 13, the second antistatic brush 14 and the grounding wire 15, when in use, the static electricity on the upper and lower surfaces of the thermal transfer film can be guided out through the grounding wire 15 by the first antistatic brush 13 and the second antistatic brush 14, thereby preventing static electricity from accumulating on the surface of the thermal transfer film after being rolled by the rolling mechanism 8, and preventing the surface of the thermal transfer film from adsorbing pollutants such as dust and metal debris, thereby effectively improving the surface cleanliness of the thermal transfer film.

[0029] The first blowing mechanism 10 and the second blowing mechanism 11 both include a first diverter pipe 102 and a second diverter pipe 104.

The airflow directions of the nozzles 105 on the first diverter pipe 102 and the second diverter pipe 104 are opposite. The first diverter pipe 102 and the second diverter pipe 104 are connected to each other through a hose 101. A connector 103 for connecting to an external air source is installed in the middle of the hose 101. When in use, the connector 103 is connected to the external air source. The external air source will supply air to the hose 101, the first diverter pipe 102 and the second diverter pipe 104 through the connector 103. The gas inside the first diverter pipe 102 and the second diverter pipe 104 will be blown from the middle position of the thermal transfer film to the edges on both sides through the plurality of nozzles 105 with opposite air outlet directions, thereby flattening the curled parts at the edges.

[0030] An adjustment piece 2 is fixedly connected to both ends of the first shunt tube 102 and the second shunt tube 104. A mounting hole 5 is defined in the middle of the adjustment piece 2. A screw 4 is threadedly connected to the adjustment piece 2. An adjustment hole 3 is defined on the inner side of the first mounting bracket 7 to cooperate with the screw 4. The first shunt tube 102 and the second shunt tube 104 are movably mounted on the inner side of the first mounting bracket 7 via the adjustment piece 2, the adjustment hole 3, and the screw 4. It should be noted that the arrangement of the adjustment piece 2, the adjustment hole 3, and the screw 4 allows the spacing between the first shunt tube 102 and the second shunt tube 104 to be adjusted during use, thereby accommodating thermal transfer films of different widths.

[0031] Both sides of the first mounting frame 7 are provided with guide mechanisms 6 mounted on the top of the base plate 1. The guide mechanisms 6 include a third mounting frame 601 mounted on the top of the base plate 1.

A gap is provided between the first guide rod 602 and the second guide rod 603 for the thermal transfer film to pass through. It should be noted that during use, the first guide rod 602 and the second guide rod 603 can guide and limit the thermal transfer film passing between them, preventing the thermal transfer film from deviating.

[0032] The laminating mechanism 8 includes a fourth mounting frame 801 mounted on the top of the base plate 1. A first laminating roller 802 and a second laminating roller 804 are rotatably mounted on the inner side of the fourth mounting frame 801. A gap is provided between the first laminating roller 802 and the second laminating roller 804 for the thermal transfer film to pass through. A motor 803 is mounted on the outer side of the fourth mounting frame 801 for driving the first laminating roller 802 to rotate. When in use, starting the motor 803 can drive the first laminating roller 802 to rotate, thereby cooperating with the second laminating roller 804 to laminarly flatten the thermal transfer film.

[0033] Working principle:

[0034] The utility model provides a flattening device for thermal transfer film. Before use, one end of the thermal transfer film is passed through between the first blowing mechanism 10 and the second blowing mechanism 11, and then through the first mounting frame 7 through the through slot 12 and then through the rolling mechanism 8, and then through the first anti-static brush 13 and the second anti-static brush 14, and then connected to the external winding device, and then the grounding wire 15 is grounded. When in use, the first blowing mechanism 10 and the second blowing mechanism 11 are connected to the external air source, and the first blowing mechanism 10 and the second blowing mechanism 11 located above and below the thermal transfer film simultaneously blow air to the two side edges of the thermal transfer film, so that the inward curled part of the edge of the thermal transfer film is flattened, and the flattened thermal transfer film will be rolled and flattened by the rolling mechanism 8. After flattening, the thermal transfer film can be guided out of the static electricity on the upper and lower surfaces through the first anti-static brush 13 and the second anti-static brush 14 through the grounding wire 15, so as to prevent static electricity from accumulating on the surface of the thermal transfer film after being rolled by the rolling mechanism 8.

Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
