Description

Technical Field

[0001] This utility model relates to the field of molding technology, and in particular to a molding device for producing laser film to enhance the aesthetics of clothing. Background Technology

[0002] Laser films generally employ computer dot matrix lithography, 3D true-color holographic technology, and multi-dimensional and dynamic imaging technology. Based on product composition, laser film products can be broadly categorized into three types: OPP laser film, PET laser film, and PVC laser film. The principle of the molding machine is to wrap a patterned master plate around the molding machine's printing roller, then heat the printing roller, and press the holographic pattern on the master plate onto the film between the printing roller and the adhesive roller, where a plastic film coated with a holographic pattern can be imprinted.

[0003] When processing laser films of different thicknesses, the existing technology adjusts the lower pressure roller by adjusting the components (to avoid excessive pressure that could damage the laser film). This requires the operator to make adjustments every time the laser film thickness is different, which is quite cumbersome. For the same film with different heights, the existing adjustment components cannot be processed well after adjustment, resulting in poor applicability. Utility Model Content

[0004] This utility model discloses a molding device for producing laser film to enhance the aesthetics of clothing. It aims to solve the technical problems of needing to adjust the laser film when the thickness is different, which is cumbersome, and the existing adjustment components cannot be well processed after adjustment for the same film with different heights, resulting in poor applicability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A molding device for producing laser film to enhance the aesthetics of clothing includes a worktable. A support frame is fixedly connected to the upper end of the worktable. A rotating roller is rotatably connected to the inner wall of the support frame. A lower pressure roller is provided on the inner wall of the support frame. A motor is provided on one side of the lower pressure roller. Rectangular rods are provided at the front and rear positions of the lower pressure roller. Rotating rods are rotatably connected to the opposite sides of the two rectangular rods. Circular blocks are fixedly connected to the front and rear positions of the two rectangular rods. A constant force spring is fixedly connected inside the circular blocks. The inner ring of the constant force spring is fixedly connected to the rotating rod. A gear is fixedly connected to the wall of the rotating rod. A U-shaped support plate is fixedly connected to the upper end of the support frame. Teeth are fixedly connected to the inner wall of one side of the U-shaped support plate, and the teeth mesh with the gear.

[0007] Preferably, a limiting plate is fixedly connected to the upper end of one of the opposite sides of the two rectangular rods;

[0008] Preferably, the support frame has sliding grooves at both the front and rear positions, and a slider is slidably connected inside the sliding groove. The slider is rotatably connected to the lower pressure roller, and the upper end of the slider is fixedly connected to the lower end of the rectangular rod.

[0009] Preferably, the upper end of the worktable is provided with guide rollers on both sides of the support frame;

[0010] Preferably, a drying device is fixedly connected to the right side of the workbench.

[0011] As can be seen from the above, the advantages of the molding device for producing laser film that enhances the aesthetics of clothing provided by this utility model are as follows: When molding laser films of different thicknesses, the constant force spring, under the action of gears and teeth, ensures that the downward pressure of the rotating rod remains constant. Even if a laser film has different heights, it can be automatically adjusted. Therefore, the molding effect will not be affected by the thickness of the laser film, thus improving work efficiency.

[0019] Reference Figures 1-3 A molding device for producing laser film to enhance the aesthetics of clothing includes a worktable 1. A support frame 3 is fixedly connected to the upper end of the worktable 1. A rotating roller 15 is rotatably connected to the inner wall of the support frame 3. The rotating roller 15 is used to bear the downward pressure of a lower pressure roller 13. The lower pressure roller 13 is provided on the inner wall of the support frame 3. The surface of the lower pressure roller 13 is patterned. A motor 11 is provided on one side of the lower pressure roller 13. The motor 11 is a driving device. In the prior art, rectangular rods 5 are provided at the front and rear positions of the lower pressure roller 13. Rotating rods 10 are rotatably connected to the opposite sides of the two rectangular rods 5. The rotating rods 10 can be positioned relative to each other. The front and rear positions of the two rectangular rods 5 are both... A circular block 12 is fixedly connected, and a constant force spring 16 is fixedly connected inside the circular block 12. The constant force spring 16 is existing technology, and the force generated after deformation hardly changes. The inner ring of the constant force spring 16 is fixedly connected to the rotating rod 10. A gear 9 is fixedly connected to the rod wall of the rotating rod 10. A U-shaped support plate 8 is fixedly connected to the upper end of the support frame 3. A tooth 7 is fixedly connected to the inner wall of one side of the U-shaped support plate 8. The constant force spring 16 applies a rotational force to the rotating rod 10, causing the gear 9 to rotate. Under the action of the tooth 7, the gear 9 moves while rotating. The tooth 7 meshes with the gear 9.

[0020] During operation, the laser film to be molded is passed between the rotating roller 15 and the lower pressure roller 13. The motor 11 drives the lower pressure roller 13 to rotate, thus processing the laser film. Due to the different thicknesses of different laser films, the lower pressure roller 13 moves upward. The lower pressure roller 13 drives the rectangular rod 5 to move, which in turn causes the rotating rod 10 to move. The rotating rod 10 drives the gear 9 to move, which rotates under the action of the teeth 7. The rotation of the gear 9 causes the rotating rod 10 to rotate, which in turn causes the inner ring of the constant force spring 16 to rotate. After the constant force spring 16 rotates, it exerts force on the rotating rod 10. The rotational force remains almost constant. It should be noted that the constant force spring 16 rotates the rotating rod 10 in its initial state, causing the rotating rod 10 to exert a downward force on the rectangular rod 5. Therefore, when the rectangular rod 5 moves up or down, the downward force of the rectangular rod 5 does not change. In this way, when molding laser films of different thicknesses, the constant force spring 16, under the action of the gear 9 and the teeth 7, ensures that the downward pressure of the rotating rod 10 remains constant. Thus, the molding effect is not affected by the thickness of the laser film, improving work efficiency.

[0021] Reference Figure 2 Limiting plates 6 are fixedly connected to the upper ends of the opposite sides of the two rectangular rods 5. The distance that the rectangular rods 5 can move downward is limited by the limiting plates 6, so that the lower pressure roller 13 will not come into contact with the rotating roller 15, thus avoiding damage to the lower pressure roller 13.

[0022] Reference Figure 3 The support frame 3 has a sliding groove 14 at both the front and rear positions. A slider is slidably connected inside the sliding groove 14. The slider is rotatably connected to the lower pressure roller 13. The upper end of the slider is fixedly connected to the lower end of the rectangular rod 5. The slider moves inside the sliding groove 14. The movement of the slider drives the lower pressure roller 13 to move, thereby ensuring the stability of the lower pressure roller 13 during operation.

[0023] Reference Figure 1 The upper end of the workbench 1 is equipped with guide rollers 4 on both sides of the support frame 3. A drying device 2 is fixedly connected to the right side of the workbench 1, and the workbench 1 is dried by the drying device 2.

[0024] Working principle: During operation, the laser film to be molded is passed between the rotating roller 15 and the lower pressure roller 13. The motor 11 drives the lower pressure roller 13 to rotate, thus processing the laser film. Due to the different thicknesses of different laser films, the lower pressure roller 13 moves upward. The lower pressure roller 13 drives the rectangular rod 5 to move, which in turn causes the rotating rod 10 to move. The rotating rod 10 drives the gear 9 to move, which rotates under the action of the teeth 7. The rotation of the gear 9 causes the rotating rod 10 to rotate, which in turn causes the inner ring of the constant force spring 16 to rotate. After the constant force spring 16 rotates, it exerts a force on the rotating rod 10. The generated rotational force remains almost constant. It should be noted that the constant force spring 16 rotates the rotating rod 10 in its initial state, causing the rotating rod 10 to exert a downward force on the rectangular rod 5. Therefore, when the rectangular rod 5 moves up or down, the downward force of the rectangular rod 5 does not change. In this way, during operation, when molding laser films of different thicknesses, the constant force spring 16, under the action of the gear 9 and the teeth 7, ensures that the downward pressure of the rotating rod 10 remains constant. Thus, during molding, the molding effect is not affected by the thickness of the laser film, improving work efficiency.
