Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping, in particular to a hot stamping foil feeding mechanism. Background Art

[0002] Hot stamping refers to the process of transferring hot stamping materials or hot stamping patterns to paper, fabrics, or other objects by hot stamping. The application of hot stamping technology on car grilles can not only improve the appearance of the car, but also protect the grille from scratches and corrosion. It is widely used by major automobile manufacturers. The vertical waterfall grille consists of a frame and a plurality of parallel and evenly spaced vertical grille bars arranged in the frame. When hot stamping on this type of car grille in the prior art, the foil film located in the grille bar area becomes waste film after completing one hot stamping, and is collected and rolled away by the waste film winding mechanism. However, there is still a lot of film paper left in the airspace between two adjacent grille bars of hot stamping that is not used, and the utilization rate of the foil film material is insufficient, resulting in material waste. Utility Model Content

[0003] The utility model aims to provide a hot stamping foil feeding mechanism, which can efficiently utilize foil materials through a displacement mechanism when hot stamping a car grille, thereby saving costs.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a hot stamping foil feeding mechanism, including a cross-section The bracket is in the shape of an arch bridge, and foil feeding roller groups are arranged at both ends of the arch body of the bracket. The foil feeding roller group includes a foil feeding roller and a foil collecting roller arranged in parallel with the roller cores. Film paper is wound on the foil feeding roller group, and a workbench for the workpiece to be hot stamped is arranged below the film paper between the foil feeding roller and the foil collecting roller. The film paper of the foil feeding roller group and the workbench are relatively displaced in the width direction of the film paper.

[0005] The utility model mainly sets the foil feeding roller group and the workbench to move relative to each other in the film paper width direction, so that the film paper between the foil feeding roller group can be translated in a direction perpendicular to the automobile grille bar after completing one hot stamping, and the film paper left after the hot stamping of the original grille bar can be applied to the next group of grille bars to be hot stamped. This scheme enables the film paper in the same grille area to be used at least twice, that is, the film paper that was originally only used for hot stamping one grille can at least meet the hot stamping needs of two grilles, greatly improving the effective utilization rate of the film paper and saving the cost of hot stamping processing.

[0012] See also Figure 1-6 The hot stamping foil feeding mechanism shown includes a cross-sectional The support 1 is in the shape of an arch bridge, and foil feeding roller groups 10 are arranged at both ends of the arch body of the support 1. The foil feeding roller group 10 includes a foil feeding roller 11 and a foil collecting roller 12 which are arranged in parallel with the roller cores. Film paper is wound on the foil feeding roller group 10, and a workbench for a workpiece to be hot stamped is arranged below the film paper between the foil feeding roller 11 and the foil collecting roller 12. The film paper of the foil feeding roller group 10 and the workbench are relatively displaced in the width direction of the film paper.

[0013] In the above scheme, when the workpiece to be hot stamped is a car grille, due to the space limitation of the hot stamping equipment, the grille can only be placed on the hot stamping workbench with its narrow side perpendicular to the width direction of the film paper. For a straight waterfall grille with grille bars parallel to its narrow side direction, after a hot stamping is completed in a local grille area, the film paper above the grille corresponding to the grille bar is consumed, forming a plurality of evenly spaced strip holes. At this time, the film paper of the foil feeding roller group 10 and the grille are relatively displaced in the film paper width direction, so that the film paper between the strip holes formed by the previous hot stamping corresponds to the next group of grille bars to be hot stamped, and the hot stamping is completed again using the film paper. When the interval between the strip holes formed by the consumption of the film paper is less than the width of the grille bar, the foil feeding roller 11 and the foil collecting roller 12 are rolled, so that the film paper is translated along the direction perpendicular to the roller core of the foil feeding roller group 10 by at least a distance of the length of the grille bar, and the above hot stamping process is continued. This scheme enables the film paper of the same area to be hot stamped on more grilles, and the effective utilization rate of the film paper is at least doubled compared with the traditional scheme, which greatly saves the film paper material and improves the economic benefits.

[0014] Preferably, a fixed base 2 is provided under the arch of the bracket 1, and the relative position of the fixed base 2 and the workbench is kept consistent, and the driving mechanism 20 on the fixed base 2 drives the bracket 1 to move relative to the fixed base 2 along the film paper width direction. When the hot stamping equipment is working, the fixed base 2 and the workbench remain stationary, and the bracket 1 and the foil feeding roller group 10 move relative to each other.

[0015] In order to adapt to the hot stamping of grids of different shapes and specifications, such as Figure 4 , Figure 5As shown, a second roller group 30 is arranged between the fixed base 2 and the workbench, which is staggered with the foil feeding roller group 10 and whose roller core is arranged at an angle with the roller core of the foil feeding roller group 10. The second roller group 30 includes a second foil feeding roller 31 with film paper wound around it and whose roller core is parallel to the second foil collecting roller 32. In the above scheme, when the workpiece to be stamped is a grid of other shapes such as inclined grid bars, due to the space limitation of the stamping equipment, in order to make the rolling direction of the film paper consistent with the length direction of the grid bars, the second roller group 30 with a roller core perpendicular to the grid bars is set to provide a better stamping effect.

[0016] When the workpiece to be stamped is a car grille with horizontal grille bars, the roller core of the second roller set 30 is perpendicular to the roller core of the foil feeding roller set 10 .

[0017] In order to stably support the movement of the bracket 1, as Figure 2 , Figure 3 As shown, a guide rail 40 is provided on the fixed base 2, the length direction of which is consistent with the displacement direction of the foil feeding roller group 10, and a slide seat 41 is extended below the arch of the bracket 1 to be embedded with the guide rail 40. Driven by the driving mechanism 20, the bracket 1 can slide smoothly on the guide rail 40 through the slide seat 41.

[0018] More specifically, if Figure 6 As shown, the driving mechanism 20 includes a screw nut assembly 21 rotatably arranged on a fixed base 2 and a motor 22 fixed on the fixed base 2. The motor 22 drives the screw 211 to rotate to make the nut 212 move, and the bracket 1 fixedly connected to the nut 212 translates accordingly.
