Description

Technical Field

[0001] The utility model relates to the field of laser films, in particular to a laser film molding device. Background Art

[0002] Laser film generally adopts computer dot lithography technology, 3D true color holographic technology, multiple and dynamic imaging technology, etc. The holographic image with rainbow dynamic and three-dimensional effects is transferred to PET, BOPP, PVC or coated substrates through molding, and then the surface of the product packaging is made to obtain a certain laser effect by lamination, hot stamping, transfer, etc. In the preparation process of laser products and other materials containing laser layers, the laser molding machine first coats the paper base or film base with a coating roller, and then enters the oven for drying, and the temperature is controlled at about 130°C to obtain a coating, and then heats and molds on the plate roller coated with the laser working plate to form a laser layer on the coating, and the temperature of the heating molding is controlled at about 180°C.

[0003] However, when the two areas of the molding roller currently on the market are in use, the heating area will increase the temperature of the normal temperature area through heat transfer, causing damage to the molded profile. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a laser film molding device to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a laser film molding device, including a molding machine, a support frame is installed on the upper surface of the molding machine, a molding roller is installed on the inner side of the support frame, the molding roller includes: a heating laser zone and a normal temperature zone, a limiting plug array is installed on the lower surface of the normal temperature zone, a limiting slot is provided on the upper surface of the heating laser zone just below the limiting plug, an insulating pad is installed on the side surface of the normal temperature zone, a cooling pipe is installed inside the normal temperature zone, and a heating wire is installed inside the heating laser zone.

[0006] As a further solution of the utility model: a transmission shaft is installed on the outer side of the heating laser zone, and an electric control box is installed on one end of the transmission shaft on the side surface of the support frame.

[0007] As a further solution of the utility model: a forming roller is arranged on the inner side of the support frame just below the molding roller, a transmission roller is installed on one side of the molding roller inside the molding machine, and a feeding roller is arranged on the side of the molding roller away from the transmission roller.

[0008] As a further solution of the utility model: the normal temperature zone is connected with the limit slot through the limit insertion rod.

[0009] As a further solution of the utility model: the interior of the cooling tube is filled with refrigerant, and the thermal insulation pad is fixedly connected to the normal temperature zone.

[0010] As a further solution of the present invention: the electric control box is electrically connected to the transmission shaft.

[0011] As a further solution of the utility model: the transmission roller and the feeding roller are both movably connected to the molding machine.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The heat insulation pad outside the normal temperature zone separates the heating laser zone and the normal temperature zone to achieve the purpose of heat insulation. At the same time, the coolant in the cooling pipe arranged inside the transmission shaft cools the normal temperature zone.

[0014] When the position of the normal temperature zone rises to the point that it is easy to affect subsequent molding during long-term use, the normal temperature zone is removed from the limit slot through the limit plug rod below, and a new normal temperature zone is replaced for continued use. When the normal temperature zone of the molding roller contacts the molding material, the laser graphics and plate seams on the outside of the normal temperature zone will not damage the laser graphics on the raw material due to the lower temperature.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-3As shown, this embodiment provides a molding device for laser film, including a molding machine 1, a support frame 2 is installed on the upper surface of the molding machine 1, a molding roller 4 is installed on the inner side of the support frame 2, the molding roller 4 includes: a heating laser zone 401 and a normal temperature zone 402, a limiting plug rod 406 is installed in an array on the lower surface of the normal temperature zone 402, a limiting card slot 407 is provided on the upper surface of the heating laser zone 401 just below the limiting plug rod 406, the normal temperature zone 402 is connected to the limiting card slot 407 through the limiting plug rod 406, a heat insulation pad 405 is installed on the side surface of the normal temperature zone 402, the heat insulation pad 405 is fixedly connected to the normal temperature zone 402, a cooling pipe 404 is installed inside the normal temperature zone 402, the interior of the cooling pipe 404 is filled with refrigerant, and a heating wire 408 is installed inside the heating laser zone 401.

[0021] like Figure 2-3 As shown, in this embodiment, a transmission shaft 403 is installed on the outer side of the heating laser zone 401, one end of the transmission shaft 403 is located on the side surface of the support frame 2 and an electric control box 5 is installed, the electric control box 5 is electrically connected to the transmission shaft 403, a forming roller 6 is arranged on the inner side of the support frame 2 just below the molding roller 4, a transmission roller 7 is installed on one side of the molding roller 6 located inside the molding machine 1, a feed roller 3 is arranged on the side of the molding roller 6 away from the transmission roller 7, and the transmission roller 7 and the feed roller 3 are both movably connected to the molding machine 1.

[0022] The working principle of the utility model is as follows: when in use, the electric control box 5 can heat the heating wire 408 inside the heating laser zone 401 through the transmission shaft 403, and the raw material on the outside of the feeding roller 3 is transmitted between the molding roller 4 and the forming roller 6. After the rotating molding roller 4 contacts the raw material on the outside of the heating laser zone 401, the laser pattern on the outside of the heating laser zone 401 is covered with the material under the action of pressure and high temperature. When the heating wire 408 heats the heating laser zone 401, the heat insulation pad 405 on the outside of the normal temperature zone 402 heats the heating laser zone 401 and The normal temperature zone 402 is separated to achieve the purpose of heat insulation. At the same time, the coolant in the cooling tube 404 arranged inside the transmission shaft 403 is used to cool the normal temperature zone 402. At the same time, when the position of the normal temperature zone 402 rises to a level that easily affects subsequent molding during long-term use, the normal temperature zone 402 is removed from the limiting slot 407 through the limiting plug rod 406 below, and a new normal temperature zone 402 is replaced for continued use. When the normal temperature zone 402 of the molding roller 4 contacts the molding material, the laser graphics and plate seams on the outside of the normal temperature zone 402 will not damage the laser graphics on the raw materials due to the lower temperature.
