Description
Technical Field
[0001] The utility model relates to the technical field of cold stamping film peeling, in particular to a cold stamping film peeling device. Background Art
[0002] Cold foil is a material that transfers metallic foil or special designs onto substrates without heating. It is widely used in packaging, labeling, and decoration. The process uses an adhesive to adhere the design to the substrate at room temperature. However, during the cold foiling process, the carrier film must be precisely peeled from the substrate to ensure the transfer of the design. Therefore, the peeling blade peeling device is a key piece of equipment. The peeling blade separates the carrier film from the substrate at a specific angle and tension. The peeling blade provides a precise separation, avoiding film residue, substrate damage, or incomplete designs, thereby ensuring the quality and stability of the cold foiling process.
[0003] Traditional cold foil stripping equipment uses a peeling blade to separate the carrier film from the substrate. During operation, the cold foil is first pressed onto the substrate using a pressure roller to adhere the pattern or metal foil. Next, the peeling blade, set at a fixed angle, mechanically peels the carrier film from the substrate. Because the peeling blade angle is difficult to adjust, manual adjustment or fixed operation is often required to ensure smooth separation of the carrier film while avoiding damage to the substrate or the cold foil. After stripping, the carrier film is reeled up, and the substrate proceeds to the next processing step.
[0004] In traditional cold foil film peeling devices, the peeling knife or peeling roller is usually fixed on a bracket during use, making it difficult to flexibly adjust the angle of the peeling knife. As a result, it is difficult for the peeling knife to always maintain the optimal angle with the substrate and cold foil, resulting in wrinkles, film rupture, or incomplete peeling during peeling.

[0031] Working principle: when the cold stamping film peeling device is needed, the cold stamping film is first passed through the guide roller 23 and then laid on the upper surface of the guide plate 3, and then peeled by the peeling knife 6. The peeled plastic film is transported upward through the preset through-hole inside the peeling knife 6 and is manually fixed to the outer wall of the collection roller 25 above. In addition, the substrate is passed through the conveying roller 29 and fixed to the outer wall of the collection roller 25 on one side. During this process, the rotating rod 7 is driven to drive the threaded rod 12 to rotate. The threaded rod 12 cooperates with the thread of the slider 10 to make the slider 10 move in the slide cylinder 8 and the pillar 4. The limit block 11 ensures that the slider 10 moves correctly. When the slider 10 moves to the inside of the slide cylinder 8, the movable plate 5 is pulled to drive one end of the peeling knife 6 to move up and down, so that the other end of the peeling knife 6 rotates with the support seat 2 as the center of the circle to achieve angle adjustment.

[0032] In addition, the driving motor 27 drives the lower conveying roller 29 to rotate, and then drives the upper conveying roller 29 to rotate synchronously through the gear 28, thereby transporting the substrate forward stably. At the same time, the rotation of the two conveying rollers 29 and the two toothed transmission belts 30 can also drive the collecting rollers 25 on both sides to rotate, thereby rewinding the processed plastic film and cold stamping film respectively. After rewinding, the C-shaped push plate 21 is pulled to drive the connecting rod 20 and the block 17 to slide, causing the spring 19 to contract. When the block 17 is completely moved to the inside of the rectangular positioning block 16, the collecting roller 25 can be removed for unloading. During installation, the clamping groove 14 of the fixing column 22 is aligned with the rectangular positioning block 16 and inserted. The spring 19 rebounds and pushes the block 17 to move to the inside of the fixing column 22, thereby realizing rapid disassembly and assembly of the collecting roller 25.
