Description

Technical Field

[0001] This utility model relates to the field of hot stamping equipment technology, specifically a rotary hot stamping device. Background Technology

[0002] Hot stamping equipment is commonly used to hot stamp patterns on the surface of bottles and is a relatively common type of printing equipment. Most existing hot stamping equipment can only move up and down to apply the hot stamping to the bottle surface. However, with technological advancements, rotary hot stamping equipment has emerged in this field.

[0003] For example, Chinese patent document CN221187820U, entitled "A Hot Stamping Equipment for Bottle Decoration Processing," details a hot stamping equipment for bottle decoration processing, including a mounting frame, a swing assembly, a lifting mechanism, and a motion compensation assembly. When the lifting mechanism drives the rubber roller to descend, it presses the hot stamping foil firmly against the surface of the substrate to be hot stamped. By incorporating the swing assembly and the motion compensation assembly, the rubber roller presses the hot stamping foil at a specific angle to the hot stamping position on the bottle, ensuring even hot stamping of the fan-shaped surface with consistent travel distance. This avoids uneven patterns, meets the needs of different products, and solves the problem of uneven patterns when hot stamping conical bottles with existing equipment, demonstrating broad market prospects.

[0004] As can be seen from the above-mentioned prior art, which discloses a technical solution for hot stamping bottles using a rotary hot stamping mechanism, it also has the following drawbacks: the hot stamping foil rotation mechanism cannot be adjusted forward and backward, nor can the hot stamping foil mechanism be adjusted forward and backward independently, nor can the hot stamping head mechanism be adjusted forward and backward. This results in poor adaptability of the equipment when adapting to bottles of different shapes and tapers. Extensive research has been conducted on this issue. Utility Model Content

[0017] 2. When adjusting the distance between the hot foil release component and the hot foil storage component and the rotation axis of the electric turntable, the distance between the hot foil release component and the hot foil storage component and the rotation axis of the electric turntable can be changed by directly adjusting the position of the platform plate and the cantilever relative to the third plate through the first position adjustment component.

[0054] Advantageously, a rotating wheel 28 is fixed to the end of the threaded shaft 26.

[0055] Advantageously, it also includes a vertical moving module 14, on which a horizontal moving module 15 is fixed. The slider of the vertical moving module 14 is connected and fixed to the back plate 12, so as to realize the left-right and up-down movement of the hot stamping foil rotating device 11 and the hot stamping head device 13, and complete the hot stamping function.

[0056] Compared to existing technologies, this invention also includes a first position adjustment component, a second position adjustment component, a third position adjustment component, and an adjustment structure to adjust the positions of the third plate 48, the hot stamping foil release component, and the hot stamping foil storage component. This allows the position of the hot stamping foil to be adjusted, facilitating hot stamping at different positions on different bottles. It also allows adjustment of the distance between the hot stamping foil and the rotation axis of the electric turntable 41, making it convenient to hot stamp bottles with different tapers.

[0057] During hot stamping, the vertical moving module 14 drives the horizontal moving module 15, the back plate 12, the hot stamping foil rotating device 11, and the hot stamping head device 13 to move downwards. The hot stamping head device 13 then stamps the hot stamping foil on its lower side onto the outer surface of the bottle.

[0058] The take-up drum 76 is hollow inside and has grooves around its perimeter. Hot stamping foil passes through the hollow area and the groove area of ​​the take-up drum 76 and can be wound onto the outer surface of the take-up drum 76.

[0059] During hot stamping, the heating rod 37 generates high heat in the internal area of ​​the housing 31, causing the pressure roller 38 to press the hot stamping foil onto the bottle for hot stamping. The third motor 33 drives the drive sprocket 34 to rotate. The drive sprocket 34 and the driven sprocket 35 are connected by a chain drive, causing the driven sprocket 35 to drive the pressure roller 38 to rotate. This ensures that during hot stamping, the pressure roller 38 can also press onto the hot stamping foil before rotating, improving the hot stamping effect and preventing the hot stamping foil from wrinkling.

[0060] When the equipment is in operation, the first motor 69 drives the second driven synchronous pulley 82 to rotate. Through the transmission of the second synchronous belt 81 and the second driving synchronous pulley 83, the feeding cylinder 58 and the hot foil placement tray 59 rotate, and the hot foil rolled in the hot foil placement tray 59 is released. At the same time, the hot foil is also being wound up. Specifically, after the second motor 78 is turned on, it drives the first driving synchronous pulley 84 to rotate. Under the power connection of the first synchronous belt 86 and the first driven synchronous pulley 85, the power cylinder 77 and the tension cylinder 73 squeeze the hot foil for conveying. The structure of the power cylinder 77, the belt 74 and the winding cylinder 76 causes the winding cylinder 76 to rotate to wind up the hot foil.

[0061] When performing hot stamping, this equipment uses a hot stamping foil release component and a hot stamping foil storage component to release the hot stamping foil. This mechanism is connected by a cantilever 52, a platform plate 46, a first slider 47, and a third plate 48. The third plate 48 is fixedly connected to a gear ring 93. Through the structure of the reducer motor 91, the drive gear 92, and the gear ring 93, the hot stamping foil release component and the hot stamping foil storage component can rotate during hot stamping. This improves the hot stamping effect and avoids pattern distortion when hot stamping containers with curved surfaces.

[0062] During hot stamping, after the pressure roller 38 moves downward, the hot stamping foil is positioned horizontally between the hot stamping foil release component and the hot stamping foil storage component, and the pressure roller 38 presses the hot stamping foil onto the outer surface of the bottle.

[0063] Because the bottles have different lengths and diameters, the equipment needs to be adjusted in the initial stage to ensure that the hot stamping head can fit the bottles. When adjusting the hot stamping head assembly, after rotating the rotary wheel 28 and the threaded shaft 26, since the threaded shaft 26 is threadedly connected to the internal threaded sleeve 25 and the internal threaded sleeve 25 is fixedly connected to the first slider 23, the first slider 23 is guided by the sliding rod 39, causing the first slider 23 to drive the bracket 29, housing 31, third motor 33, drive sprocket 34, driven sprocket 35 and pressure roller 38 to move back and forth, so that the pressure roller 38 moves above the area to be hot stamped.

[0064] Since the position of the pressure roller 38 is adjusted, the position of the hot stamping foil device also needs to be adjusted. When adjusting the hot stamping foil device, two adjustment components are set to adjust the position of the second plate 43 relative to the first plate 42, and to adjust the position of the platform plate 46, the cantilever 52 and the hot stamping foil device relative to the third plate 48.

[0065] After rotating the second threaded shaft 54, since one end of the second threaded shaft 54 ​​is rotatably set on one side of the first plate 42, after the second threaded shaft 54 ​​is threadedly connected with the internal thread seat 53, the front and rear positions of the second plate 43, electric turntable 41, third plate 48, platform plate 46, cantilever 52, hot stamping foil release assembly and hot stamping foil storage assembly relative to the first plate 42 can be adjusted so that the hot stamping foil is located at the bottom of the pressure roller 38 after the hot stamping foil release assembly and hot stamping foil storage assembly are adjusted.

[0066] When adjusting the position of the platform plate 46, cantilever 52, hot foil release component, and hot foil storage component relative to the third plate 48, after rotating the first threaded shaft 45, since the first threaded shaft 45 is threadedly connected to the platform plate 46, the platform plate 46, cantilever 52, hot foil release component, and hot foil storage component will slide back and forth on the first slide rail 51. Since the electric turntable 41 is fixedly installed on the second plate 43, and the rotation axis of the electric turntable 41 remains unchanged on the second plate 43, adjusting the position of the platform plate 46 will also adjust the distance between it and the rotation axis of the electric turntable 41, so that the rotation diameter of the platform plate 46, cantilever 52, hot foil release component, and hot foil storage component can be changed to adapt to bottles with different tapers, so that the hot foil can better adhere to the outer surface of the bottle when rotating for hot foil stamping.

[0067] For the hot foil release component and the hot foil storage component, since the third threaded shaft 68 is threadedly connected to the cantilever 52 and the guide rod 56 is slidably connected to the cantilever 52, the front and rear positions of the hot foil release component and the hot foil storage component can be adjusted by rotating the third threaded shaft 68, so as to realize the front and rear position adjustment function of the hot foil.

[0068] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
