Description

Technical Field

[0001] The utility model relates to a hot stamping machine, in particular to an automobile grid hot stamping machine. Background Art

[0002] The hot stamping process is to transfer the coating pre-coated on the carrier foil to the product to be decorated by heating and pressurizing. The principle of hot stamping of automobile grille is to put the grille on the fixture, heat the metal foil to high temperature, and then press it down quickly with high pressure to make the metal foil and grille in close contact. The coating on the metal foil is transferred to the surface of the grille through the action of high temperature and high pressure, so that the surface of the grille has a metallic luster effect.

[0003] However, due to the dust or foreign matter contaminated during the transportation and storage of automobile grilles, the hot stamping is not firm, bubbles and hot stamping surface deformation occur. Currently, the grilles are mainly surface treated manually. Workers polish and clean the air intake grilles, which increases the workers' workload and also reduces the hot stamping efficiency of automobile grilles.

[0004] Therefore, it is necessary to design a car grid hot stamping machine that can automatically clean the grid surface. Utility Model Content

The two electric sliders 9 are commonly fixed with a storage rack 10 for placing the car grid.

[0029] When the grid needs to be hot stamped, the metal foil film coil is firstly sleeved on one of the electric conveying rollers 4, and then one end of the metal foil film is pulled out, passed between the guide rollers 7 on the left and right sides of the mounting frame 2, and then wound around another electric conveying roller 4, and then the grid is placed on the storage rack 10, and then the servo motor 13 is started, and the output shaft of the servo motor 13 rotates to drive one of the cleaning brushes 11 to rotate, and then the remaining cleaning brushes 11 are driven to rotate through the synchronous wheel 14 and the synchronous belt 15, and then the electric slide rail 8 is started, so that the electric slide rail 8 is driven to be transported backward through the electric slider 9 and the storage rack 10, and when the grid moves to the bottom of the cleaning brush 11, the cleaning brush 11 rotates to wipe the surface of the grid, so as to achieve the purpose of automatically cleaning the surface of the grid, and prevent the grid from being damaged due to dust attached to the surface during hot stamping and film application.
