Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] In the description of the embodiments of the utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection", "installation" should be understood broadly, for example, "connection" can be detachable connection, can also be undetachable connection, can be direct connection, also can be indirect connection through intermediate medium. In addition, "communication" can be direct communication, also can be indirect communication through intermediate medium. Among them, "fixing" refers to the relative position relationship of each other after connection does not change. The orientation language mentioned in the embodiments of the utility model, for example, "inner", "outer", "top", "bottom" and the like, is only the direction of the drawing, therefore, the orientation language is used for better, more clearly illustrating and understanding the embodiments of the utility model, and is not indicated or implied that the indicated device or element must have a particular orientation, a particular orientation structure and operation, therefore, it cannot be understood as the limitation of the embodiments of the utility model.

[0025] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0026] See also Figures 1-4 The utility model provides a molding machine for laser transfer film processing, including a workbench 1, a pair of hot stamping shafts 11 are provided above the workbench 1, a receiving shaft 12 is provided above the workbench 1 and on the downstream side of the hot stamping shaft 11, a bracket 2 extending vertically upward is fixed on one side of the area between the hot stamping shaft 11 and the receiving shaft 12 above the workbench 1, and a conveying roller group 3 for guiding and conveying the laser transfer film is provided on the bracket 2. A cooling box 5 is provided on the top of the bracket 2 above the conveying roller group 3, and an air inlet cylinder 6 is provided on the top of the cooling box 5. A fan 61 is installed in the air inlet cylinder 6, and an air blowing port 51 extending along the length direction of the cooling box 5 is provided at the bottom of the cooling box 5 for blowing air downward to the conveying roller group 3.

[0027] After the utility model utilizes two hot stamping shafts 11 to perform hot stamping processing on the laser transfer film, the laser transfer film is guided to the conveying roller group 3, and finally guided by the conveying roller group 3 to be conveyed to the receiving shaft 12 for winding. The fan 61 in the air inlet cylinder 6 works to suck the external air into the air inlet cylinder 6 and introduce it into the cooling box 5. Finally, it is blown downward through the blowing port 51 onto the laser transfer film at the conveying roller group 3. The laser transfer film after hot stamping can be cooled by blowing, so that the hot stamping area can be cooled and formed before being received, thereby effectively ensuring the quality of the hot stamping process.

[0028] In addition, four air inlet cylinders 6 are provided, and the four air inlet cylinders 6 are arranged in an array along the length direction of the cooling box 5. A fan 61 is installed in each air inlet cylinder 6. Four air inlet cylinders 6 are arranged in an array along the length direction of the cooling box 5 to ensure that the air flow range is sufficient to cover the length of the cooling box 5, thereby ensuring sufficient airflow required for blowing cooling.

[0029] like Figure 3As shown, the bottom of the cooling box 5 is provided with two air outlets 51, which are distributed on both sides of the conveying roller group 3, thereby forming two downward air flows, and the two cooling air flows are located on both sides of the laser transfer film wound on the conveying roller group 3, which effectively improves the cooling effect and accelerates the cooling and forming effect of the hot stamping area. The cooling box 5 is fixed with a flow divider 52 with a triangular cross section, the top corner of the flow divider 52 is opposite the air inlet cylinder 6, and the two bottom corners of the flow divider 52 are respectively connected to the corresponding air outlet 51. After the air flow is vertically introduced into the cooling box 5 from the air inlet cylinder 6, the air flow can be divided to both sides through the flow divider 52, and the air flow can be gradually guided to the corresponding air outlet 51 through the two slopes of the flow divider 52, thereby ensuring the effective flow of the air flow.

[0030] In addition, the bottom of the cooling box 5 is provided with a frame-shaped extension cover 501 corresponding to the positions of the two air outlets 51, which can extend the limiting path of the downward air flow and ensure that the downward air flow is stable enough.

[0031] As shown in Figure 2 and Figure 3 The conveying roller group 3 includes four guide rollers A31, which are arrayed and installed on the side of the support 2 in the vertical direction. After the laser transfer film is introduced from the hot stamping shaft 11, it is sequentially reversed and wound around each guide roller A31 from bottom to top, and then wound on the material collecting shaft 12. The four guide rollers A31 reversely convey the laser transfer film from bottom to top. Since the air flow intensity emitted from the air outlet 51 decreases downward, the strong air flow emitted from the air outlet 51 does not directly blow on the just hot stamped laser transfer film, thereby further improving the hot stamping forming quality, and the overall structure layout is reasonable and has high practicability.

[0032] The side of the support 2 close to the bottom guide roller A31 is provided with a guide roller B4. After the laser transfer film is reversed and introduced from the top guide roller A31, it is wound around the bottom of the guide roller B4 and then wound on the material collecting shaft 12. The guide roller B4 guides the laser transfer film introduced from the top guide roller A31 downward, thereby avoiding the interference of the air flow emitted from the air outlet 51 close to the material collecting shaft 12.

[0033] It is worth mentioning that the laser transfer film processing mold pressing machine provided by the present application improves the hot stamping mold pressing machine of the reference patent with the authorization announcement No. CN207697254U. The specific installation mode of the hot stamping shaft 11 and the material collecting shaft 12 and the working principle, the remaining parts and the working principle are the same as those of the reference patent, and therefore will not be described in detail.

[0034] 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.
