The application fields of laser materials are very wide, and they have been rapidly promoted in industries such as food, medicine, daily chemicals, tobacco and alcohol, clothing, gift packaging, and decorative materials.

[0003] The traditional laser embossing method is to wrap the laser embossing plate with a pattern on the plate roller of the embossing machine, then heat the plate roller, pass the plastic film coated with the coating that can emboss the holographic pattern between the plate roller and the rubber pressing roller of the embossing machine, and use the pressing device and transmission device of the embossing machine to emboss the holographic pattern on the laser embossing plate onto the plastic film. Before this, it is necessary to preheat the laser substrate with a preheating roller to soften its surface coating. However, the current preheating roller structure is often fixed, which cannot fully soften the laser substrate coating, affecting subsequent operations.

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Reference Figure 1-3 , an embodiment of the utility model is proposed, a laser substrate preheating device for laser film processing, comprising an equipment box 1, both ends of the inner side of the equipment box 1 are horizontally rotatably connected with a rotating seat 2, the inner surfaces of the two rotating seats 2 are vertically fixedly connected with movable sleeves 3, the insides of the two movable sleeves 3 are respectively slidably connected with sliding rods 4 along their length directions, the top ends of the two sliding rods 4 are horizontally fixedly connected with a horizontal plate 5, a device frame 8 is horizontally fixedly connected between the two side walls of the equipment box 1, a first extension block 9 is horizontally fixedly connected to the rear side surface of the device frame 8, and a first bevel gear 10 is fixedly connected to one side surface of the first extension block 9;

[0021] The bottom end of the horizontal plate 5 is vertically fixedly connected with a vertical tube 11, and the outer surface of the vertical tube 11 is slidably connected with a sliding tube 12 along its length direction. The bottom end of the sliding tube 12 is rotatably connected with a second bevel gear 14 that meshes with the first bevel gear 10. The top end of the second bevel gear 14 is vertically penetrated with a mounting hole, and the inside of the mounting hole is fixedly connected with a threaded sleeve 15, and the internal thread of the threaded sleeve 15 is threadedly connected with a threaded rod 16, and the top end of the threaded rod 16 is fixedly connected to the bottom end of the horizontal plate 5.

[0022] The central axes of the vertical tube 11, the sliding tube 12, the second bevel gear 14 and the threaded rod 16 are located on the same straight line.

[0023] A second extension block 17 is laterally fixedly connected to the rear surface of the device frame 8 and located on one side of the first extension block 9 . A third bevel gear 18 is laterally rotatably connected to a surface of one side of the other end of the second extension block 17 . The third bevel gear 18 is meshed with the second bevel gear 14 .

[0024] The central axes of the two rotating seats 2, the first bevel gear 10 and the third bevel gear 18 are located on the same straight line.

[0025] Both ends of the upper surface of the transverse plate 5 are fixedly connected with mounting seats 6 , and a preheating roller 7 is rotatably connected between the two mounting seats 6 .

[0026] The two side surfaces of the device box 1 of the device are fixedly connected with servo motors, and the output shafts of the two servo motors respectively penetrate the two side surfaces of the device box 1 and are respectively fixedly connected to the two rotating seats 2. The two servo motors run synchronously under the control of the controller and rotate periodically in two directions. During the rotation of the two rotating seats 2, the movable sleeves on the inner side will drive the two sliding rods 4 to swing back and forth synchronously. In this process, the vertical tube 11 and the sliding tube 12 at the bottom end of the cross plate 5 will drive the second bevel gear 14 at its bottom end to move. Since the central axes of the two rotating seats 2 and the first bevel gear 10 are located in the same straight line, the second bevel gear 14 will also be centered on the central axis of the first bevel gear 10. The center of the circle performs circular motion, and since the two are meshed and the first bevel gear 10 is a fixed structure, the second bevel gear 14 will also continue to rotate. During its rotation, the internal threaded sleeve 15 will rotate synchronously, thereby driving the threaded rod 16 to move. Since the central axes of the vertical tube 11, the sliding tube 12, the second bevel gear 14 and the threaded rod 16 are located in the same straight line, the direction of movement of the threaded rod 16 is the same as the length direction of the vertical tube 11 and the sliding tube 12, thereby driving the cross plate 5 to perform periodic interval extension and shortening movements, and the preheating roller 7 at the top of the cross plate 5 will also perform synchronous movement. The preheating roller 7 can also preheat the laser substrate within a range, thereby improving the preheating effect of the device.

[0027] The third bevel gear 18 can limit the second bevel gear 14 to prevent it from deviating to the other side of the first bevel gear 10 and causing the first bevel gear 10 and the second bevel gear 14 to separate.

[0028] The preheating roller 7 is provided with a heating wire inside. When heated by the heating wire, the temperature of the preheating roller itself will rise. The preheating roller is attached to the bottom of the laser substrate, that is, the coating film, to heat the coating above it, thereby softening it.

[0029] Furthermore, a spring 13 is sleeved on the outer surface of the vertical tube 11 , and the top and bottom ends of the spring 13 are fixedly connected to the lower surface of the horizontal plate 5 and the top end of the sliding tube 12 respectively.

[0030] Furthermore, the spring 13 always applies a force to the sliding tube 12 in the direction of the first bevel gear 10, so during the extension or shortening of the cross plate 5 of the device, the second bevel gear 14 can always keep in close contact with the first bevel gear 10 under the action of the elastic force of the spring 13, thereby ensuring that the two are always in a meshing state.

[0031] During operation, servo motors are fixedly connected to the surfaces of both sides of the equipment box of the device. The two servo motors are controlled by a controller to run synchronously. The two servo motors will drive the two rotating seats 2 to rotate back and forth synchronously. During the rotation of the rotating seat 2, it will drive the sliding rod 4 to perform periodic swinging motion, and the cross plate 5 will also move synchronously. During its movement, the vertical tube 11 and the sliding tube 12 drive the second bevel gear 14 at its bottom to move, and the second bevel gear 14 will rotate under the action of the first bevel gear 10. During its rotation, the threaded sleeve 15 inside it will also rotate, thereby driving the threaded rod 16 to move in the length direction of the vertical tube 11, thereby driving the cross plate 5 to move synchronously. Therefore, when the device is running, the preheating roller 7 at the top of the cross plate will periodically extend and shorten, so that the laser substrate can be preheated within a range, thereby improving the preheating effect of the device.

[0032] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
