Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features.
[0026] Please refer to Figures 1-4 The utility model provides a kind of positioning anti-fake film hot stamping post drying device, including drying box 1, drying box 1 one side is equipped with feed inlet 11, a pair of upper and lower symmetrical arrangement feed roller 111 is rotatably installed in feed inlet 11, the positioning anti-fake film after hot stamping is introduced to drying box 1 between the two feed rollers 111 in feed inlet 11, the other side is equipped with discharge port 12, a pair of upper and lower symmetrical arrangement discharge roller 121 is rotatably installed in discharge port 12, the positioning anti-fake film after drying is introduced to drying box 1 outside between the two discharge rollers 121 in discharge port 12, realizes the conveying of positioning anti-fake film in drying box 1.
[0027] The heat conduction seat 2 is provided with a through cavity 21 for the positioning anti-fake film to pass through, and the upper and lower surfaces of the heat conduction seat 2 are respectively fixed with an electric heating plate 3, the electric heating plate 3 can generate heat when powered, and the specific heating principle adopts the prior art. In addition, a temperature controller 01 is arranged on the outer wall of the drying box 1, and the electric heating plate 3 is controlled by the temperature controller 01, so that the heating temperature of the electric heating plate 3 can be adjusted through the temperature controller 01, and the specific control and adjustment mode adopts the prior art, which will not be described in detail.
[0028] The heat conduction seat 2 is provided with a through cavity 21 for the positioning anti-fake film to pass through, and the upper and lower surfaces of the heat conduction seat 2 are respectively fixed with an electric heating plate 3, the electric heating plate 3 can generate heat when powered, and the specific heating principle adopts the prior art. In addition, a temperature controller 01 is arranged on the outer wall of the drying box 1, and the electric heating plate 3 is controlled by the temperature controller 01, so that the heating temperature of the electric heating plate 3 can be adjusted through the temperature controller 01, and the specific control and adjustment mode adopts the prior art, which will not be described in detail.
[0029] When the positioning anti-fake film after hot stamping is dried by the drying device, the upper and lower electric heating plates 3 are powered to generate heat, the heat is transferred to the heat conduction seat 2, the heat conduction mechanism 4 absorbs the heat on the heat conduction seat 2 and transfers it to the side of the feeding port 11, and the preheating zone is formed between the two heat conduction mechanisms 4. Since the heat conduction mechanism 4 is farther away from the heat conduction seat 2 as it is closer to the feeding port 11, the temperature in the preheating zone is lower as the heat is consumed and dispersed, and the temperature in the through cavity 21 is the highest. When the positioning anti-fake film passes through the preheating zone, the hot stamping area on the film can be preheated and dried to preliminarily evaporate excess moisture and solvent, and the entire film body can be heated more uniformly through the preheating stage, avoiding uneven heating caused by direct high-temperature drying, improving the drying effect, and helping the subsequent drying process to be faster and more efficient, thereby shortening the overall drying time.
[0030] In addition, in the direction of movement of the positioning anti-fake film, the drying temperature gradually increases in the area, and the preheating can make the anti-fake film gradually adapt to the temperature change, thereby reducing the risk of deformation, cracking or damage of the film body caused by sudden temperature change, and helping to maintain the flatness and integrity of the film.
[0031] As shown in Figures 2-4 The heat conduction mechanism 4 includes a flow guide device 42 and a plurality of heat conduction pipes 41, the plurality of heat conduction pipes 41 are arrayed and installed on the heat conduction seat 2 in the width direction of the drying box 1, and the end portion of each heat conduction pipe 41 near the discharge port 12 is provided with a flow guide device 42, and the flow guide device 42 is used to form an air flow in the heat conduction pipe 41 from the discharge port 12 to the side of the feeding port 11.
[0032] The air guide device 42 comprises an air guide box 421, an air inlet pipe 422 and a fan 423. The air guide box 421 is fixed on the end of the heat conduction pipe 41 close to the discharge port 12. The inner wall of the air guide box 421 is uniformly provided with air guide holes 4201 corresponding to the heat conduction pipes 41. The surface of the air guide box 421 away from the heat conduction pipes 41 is arrayed with at least three air inlet pipes 422 along the width direction of the drying box 1, which are communicated with the inside of the air guide box 421. The fan 423 is installed in each air inlet pipe 422.
[0033] Through the operation of the fan 423, air is sucked into the air inlet pipe 422 and introduced into the air guide box 421. The air in the air guide box 421 is introduced into the heat conduction pipes 41 through the air guide holes 4201, forming an air flow flowing to the side of the feeding port 11. The heat conduction pipes 41 are made of aluminum, which can absorb the heat of the heat conduction seat 2 and transfer the heat to the internal air flow, forming a flowing preheating air flow with lower temperature closer to the feeding port 11 side, and gradually transferring the heat to the heat conduction pipes 41, realizing the preheating of the positioning anti-fake film.
[0034] When the fan 423 works to suck air into the heat conduction pipes 41 and discharge it to the outside of the drying box 1 through the ports of the heat conduction pipes 41, in order to ensure the air pressure balance in the drying box 1, external air can enter the drying box 1 through the discharge port 12. Since the external air is reduced and enters the drying box 1 from the side close to the discharge port 12, the positioning anti-fake film after drying can be cooled, saving the waiting time after drying, facilitating the next process, effectively improving the production efficiency.
[0035] In addition, the box wall of the drying box 1 is provided with air inlets 101 above and below the discharge port 12. The air inlets 101 are used for external air to enter the drying box 1, ensuring sufficient air intake, and the air inlets 101 are arranged above and below the discharge port 12. When the positioning anti-fake film is drawn out from the discharge port 12, it is convenient to cool the film from the upper and lower sides.
[0036] As shown in Figure 1 The side of the drying box 1 is provided with a side opening 102, and the side of the drying box 1 is hingedly installed with a side door body 103 for plugging the side opening 102. By arranging the side opening 102 and the side door body 103 on the side of the drying box 1, and opening the side door body 103, it is convenient to draw the positioning anti-fake film in the drying box 1, and it is also convenient to maintain and repair the internal structure components of the drying box 1.
[0037] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
