Description

Technical Field

[0001] The invention belongs to the field of label transfer, and in particular relates to an anti-counterfeiting gold-stamping label transfer device. Background Art

[0002] Anti-counterfeiting hot stamping labels are high-end labels that combine anti-counterfeiting technology and hot stamping technology. They are widely used in luxury goods, high-end cosmetics, electronic products and other fields. Its main purpose is to prevent counterfeit and inferior products, protect brand rights and interests, and at the same time improve the grade and aesthetics of products. Anti-counterfeiting hot stamping labels usually contain complex anti-counterfeiting features, such as micro-text, optically variable inks, holographic images, etc. These features are difficult to copy and can effectively distinguish the authenticity. The hot stamping process gives the label a golden or other metallic luster, increasing the visual impact.

[0003] When transferring the hot stamping label, in the hot stamping machine, the hot melt adhesive layer on the hot stamping paper is melted by heating and pressurizing, forming adhesion with the surface of the substrate; as the hot melt adhesive melts, the graphic layer or vapor-deposited layer on the hot stamping paper is separated from the carrier film by the action of the release agent and transferred to the substrate; then the hot melt adhesive is solidified through a cooling process to ensure that the pattern is firmly attached to the substrate, thus completing the label transfer.

[0004] The surface of the substrate is not entirely flat. Some cylindrical substrates (such as cylinder products) have curved surfaces. Traditional hot pressing cannot make the hot stamping paper fit the surface of the substrate, thus affecting the transfer effect. Therefore, an anti-counterfeiting hot stamping label transfer device is proposed. Summary of the invention

[0032] like Figure 2 As shown, the positioning and clamping assembly 4 includes two V-shaped clamping blocks 41 that can slide synchronously in opposite directions. The two V-shaped clamping blocks 41 are synchronously close to each other, so as to realize the positioning and fixing of the product (cylindrical) to facilitate the subsequent label transfer;

[0033] In this embodiment, the two V-shaped clamps 41 are both slidably connected to the mounting plate 2, and two first fixing plates 43 are provided on the mounting plate 2. A first screw rod 42 is rotatably connected between the two first fixing plates 43. The two ends of the first screw rod 42 are respectively provided with a first external thread 421 and a second external thread 422 with opposite rotation directions and equal pitches. The first external thread 421 and the second external thread 422 respectively penetrate the two V-shaped clamps 41 and are threadedly connected thereto. By providing a motor on one of the first fixing plates 43 to drive the second screw rod 42 to rotate, the two V-shaped clamps 41 can be synchronously slid in the opposite direction, so as to realize the centering clamping and fixing of the cylindrical product.

[0034] Furthermore, in order to ensure the stability of clamping the cylindrical product, the second screw 42 needs to have a self-locking property, that is, the thread lead angles of the first external thread 421 and the second external thread 422 are smaller than the equivalent friction angle.

[0035] Of course, the method of driving the two V-shaped clamps 41 to slide synchronously in opposite directions includes but is not limited to the second screw rod 42 and other structures in this embodiment. In some embodiments, two cylinders can also be set on the mounting plate 2 to directly drive the two V-shaped clamps 41 to slide synchronously in opposite directions.

[0036] The upper end of the base 1 is provided with a stamping component 6, and a hot stamping paper 5 is provided above the product. The stamping component 6 can press the hot stamping paper 5 onto the surface of the product to realize label transfer;

[0037] like Figure 3As shown, the stamping assembly 6 includes a mounting frame 61 that can slide horizontally, the sliding direction of the mounting frame 61 is perpendicular to the axial direction of the product, a second cylinder 62 is provided at the upper end of the mounting frame 61, a connecting pipe 63 is fixed to the end of the driving shaft of the second cylinder 62, the lower end of the connecting pipe 63 is slidably connected to a connecting frame 64 along the vertical direction, and the connecting pipe 63 and the connecting frame 64 are elastically connected by a first spring 66; the lower end of the connecting frame 64 is rotatably connected to a pressing roller 65, the axial direction of the pressing roller 65 is parallel to the axial direction of the product, and can be heated;

[0038] When in use, first control the mounting plate 2 to rise so that the product contacts the hot stamping paper 5, and then, driven by the second cylinder 62, the pressing roller 65 can press the hot stamping paper 5 onto the product (the first spring 66 is compressed), and, in order to imprint the label on the curved surface of the product, the mounting frame 61 is controlled to slide horizontally, so that the pressing roller 65 can roll and imprint along the curved surface of the product to improve the pressing quality and uniformity.

[0039] In this embodiment, if Figure 4 and Figure 5 As shown, a limiting groove 631 is provided on the connecting tube 63, and a limiting block 641 is provided on the connecting frame 64. The limiting block 641 is located in the limiting groove 631. The two ends of the first spring 66 are respectively fixedly connected to the connecting frame 64 and the connecting tube 63. Under the action of the elastic force of the first spring 66, the limiting block 641 can be tightly attached to the bottom of the limiting groove 631, thereby preventing the connecting frame 64 from being separated from the connecting tube 63.

[0040] In this embodiment, the mounting frame 61 is slidably connected to the base 1, and the sliding direction is perpendicular to the axial direction of the product. Figure 6 As shown, two second fixing plates 11 are provided at the upper end of the base 1, and a second screw rod 7 is rotatably connected between the two second fixing plates 11. The second screw rod 7 passes through the mounting frame 61 and is threadedly connected thereto. By arranging a motor between one of the second fixing plates 11 to drive the second screw rod 7 to rotate, the mounting frame 61 can be driven to slide.

[0041] In order to ensure that the mounting bracket 61 remains stable after the sliding position is adjusted, the second screw rod 7 needs to have a self-locking property, that is, the thread lead angle of the second screw rod 7 is smaller than the equivalent friction angle.

[0042] Of course, the method of driving the mounting frame 61 to slide and adjust includes but is not limited to the second screw rod 7 and other structures in this embodiment. In some embodiments, linear driving components such as cylinders and telescopic rods can also be set on the base 1 to directly drive the mounting frame 61 to slide.

[0043] In addition, in this embodiment, the hot stamping paper 5 is tensioned above the product by the winding machine, thereby ensuring the quality of the hot stamping label transfer.

[0044] A limit assembly 8 is provided on the mounting frame 61 to control the stamping timing of the stamping assembly 6, so as to prevent the product from being too far away from the hot stamping paper 5, which may cause excessive deformation of the hot stamping paper 5 when the pressure roller 65 presses downward, thereby affecting the transfer quality;

[0045] like Figure 7 As shown, the limit assembly 8 includes a lifting rod 81, which passes through the mounting frame 61 in the vertical direction and is slidably connected thereto, a second spring 83 is sleeved on the lifting rod 81, a pressing plate 82 is fixed to the lower end of the lifting rod 81, and the two ends of the second spring 83 are respectively fixedly connected to the mounting frame 61 and the pressing plate 82. Under the elastic force of the second spring 83, the pressing plate 82 can be tightly attached to the upper end of the mounting plate 2, and the pressing plate 82 can be lifted and lowered as the mounting plate 2 is lifted and lowered;

[0046] A support base 84 is fixed on the mounting frame 61, and a rotating shaft 85 is rotatably connected to the support base 84. A first gear 86 and a second gear 87 are fixed to both ends of the rotating shaft 85, and a first rack 811 is provided on the top of the lifting rod 81. The first rack 811 and the first gear 86 are meshed with each other; Figure 3 As shown, a third fixing plate 611 is provided at the upper end of the mounting frame 61, a second rack 88 is slidably connected to the third fixing plate 611, the second rack 88 is meshed with the second gear 87, a stopper 89 is fixed to the lower end of the second rack 87, a fourth fixing plate 632 is provided at one side of the connecting tube 66, the stopper 89 is located below the fourth fixing plate 632 and can prevent the connecting tube 66 from descending (i.e., preventing the pressure roller 65 from descending);

[0047] When the mounting plate 2 is at the lowest end, the blocking rod 89 is located below the fourth fixed plate 632 and can prevent the connecting tube 66 from descending; as the mounting plate 2 rises, the first rack 811 is driven to rise, thereby driving the blocking rod 89 to slide in the direction away from the fourth fixed plate 632; when the mounting plate 2 rises to contact the hot stamping paper, the blocking rod 89 has completely left the fourth fixed plate 632, allowing the connecting tube 66 to descend; thereby achieving control of the action timing of the pressure roller 65, and the downward pressure of the pressure roller causes excessive deformation of the hot stamping paper 5, thereby affecting the transfer quality.

[0048] Working principle:

[0049] The cylindrical product is positioned and fixed by setting a positioning clamping component 4 on the installation plate 2 that can be raised and lowered, and the stamping component 6 includes a mounting frame 61 that can slide horizontally, a connecting pipe 63 that can be raised and lowered is set on the mounting frame 61, and a first spring 66 is set between the connecting pipe 63 and the connecting frame 64 to achieve elastic sliding connection, and a heated pressing roller 65 is rotatably connected to the lower end of the connecting frame 64, and the pressing roller 65 descends to press the hot stamping paper on the curved surface of the product to improve the stamping quality. By setting a limit component 8 on the mounting frame 61, the stamping timing of the stamping component 6 is controlled to prevent the product from being too far away from the hot stamping paper 5, which will cause excessive deformation of the hot stamping paper 5 when the pressing roller 65 presses down, thereby affecting the transfer quality.
