Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to an efficiency-enhancing hot stamping equipment for continuous and reusable film materials. Background Technology

[0002] Currently, hot stamping is a widely used packaging decoration technique, especially in the tobacco and alcohol packaging industries, where approximately 70% of products utilize this technology. Hot stamping is extensively applied for product decoration and anti-counterfeiting. Existing hot stamping equipment includes at least a film feeding assembly, a guide roller assembly, and a film take-up assembly. The hot stamping film is fed out from the feeding assembly, passes through the guide roller assembly, and then simultaneously adheres to the material to be printed. The metallic pattern plating on the hot stamping film is transferred to the printed material. Finally, the film take-up assembly collects the hot stamping film.

[0003] Currently, hot stamping film, which is used as a raw material, is usually only used for one hot stamping. The metal pattern coating between two adjacent hot stamping positions on the hot stamping film is not fully utilized and can only be discarded along with the used cold stamping film waste. Hot stamping film is expensive and is one of the main sources of cost in the hot stamping process. On the other hand, the graphic information on the waste film after one hot stamping can easily expose certain product design content, which is also detrimental to the anti-counterfeiting of product packaging.

[0004] To address production costs and prevent the leakage of anti-counterfeiting information, existing methods for handling waste hot stamping film involve collecting it with a winding device and then reloading it into the unwinding assembly of an efficiency-enhancing hot stamping equipment for reuse. For example, patent number 202510636509.3 discloses a cold stamping equipment that enables multiple uses of hot stamping film. This equipment rewinds and processes the waste film after the first hot stamping and performs a second hot stamping, using tracking photoelectric sensors and floating tension control rollers to ensure accurate transfer of graphic information to the substrate, thus achieving the reuse of the waste film. However, these devices still have the following drawbacks: the waste film after the first hot stamping requires pre-collection, machine shutdown, and reinstallation and replacement of the hot stamping film, making real-time, continuous film reuse impossible and resulting in low film utilization efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an efficiency-enhancing hot stamping equipment for continuous and reusable film materials.

[0006] The purpose of this utility model is achieved by the following technical solution: an efficiency-enhancing hot stamping equipment for continuous and reusable film material, including a film feeding assembly, a hot stamping assembly, a guide roller assembly, a film take-up assembly, and a film reuse adjustment assembly; the hot stamping film material is fed out from the film feeding assembly, passes around the guide roller assembly, and is simultaneously bonded to the printed material by the transfer of the hot stamping assembly at the hot stamping station, and the metal pattern plating layer to be transferred on the hot stamping film material is transferred to the printed material, and finally the hot stamping film material is recovered by the film take-up assembly; The film reuse adjustment component is located at the rear end of the hot stamping station. After one hot stamping process, the hot stamping film is turned by the film reuse adjustment component and its displacement is adjusted to avoid the already hot stamped position. Then it enters the hot stamping process again and is bonded to the printed material through the re-transfer of the hot stamping component.

[0007] Furthermore, the membrane reuse adjustment assembly includes a membrane steering assembly and an adjustment roller; The film turning assembly includes a first film-passing roller, a second film-passing roller, and a third film-passing roller arranged in parallel, and an inclined turning roller disposed between the first film-passing roller and the second film-passing roller. The adjusting roller is movably disposed between the second film-passing roller and the third film-passing roller. After one hot stamping process, the hot stamping film material passes through the first film-passing roller, the inclined turning roller, and the second film-passing roller in sequence. The movement of the adjusting roller adjusts the displacement of the hot stamping film material to avoid the already hot stamped position.

[0008] Furthermore, the inclined steering roller slides back and forth along the length direction of the film-passing roller via a first sliding mechanism; the first sliding mechanism includes a first mounting plate and a first slide rail, the inclined steering roller is mounted on the first mounting plate, and the first mounting plate is slidably mounted on the first slide rail via a first slider.

[0009] Furthermore, the adjusting roller slides back and forth along the length direction perpendicular to the film-passing roller via a second sliding mechanism; the second sliding mechanism includes a second mounting plate and a second slide rail, the adjusting roller is mounted on the second mounting plate, and the second mounting plate is slidably mounted on the second slide rail via a second slider.

[0010] Furthermore, the second mounting plate is provided with a stop handle for locking the adjusting roller in a preset position on the second slide rail.

[0011] Furthermore, the film feeding assembly, hot stamping assembly, turning roller assembly, film taking assembly, and film reuse adjustment assembly are integrated on the same machine body to form an independent unit module. The unit modules can be added or removed along the substrate printing process direction and along the entire printing process direction.

[0012] Furthermore, the hot stamping assembly includes two hot stamping rollers, one of which is a movable hot stamping roller for moving closer to or further away from the other hot stamping roller.

[0013] Furthermore, the enhanced hot stamping equipment for continuous and reusable film material also includes a UV curing lamp, which is located after the hot stamping station.

[0014] Furthermore, this continuously reusable film material-enhancing hot stamping equipment also includes an unwinding assembly, a rewinding assembly, and a printing mechanism. The unwinding assembly and the rewinding assembly are respectively located at the beginning and end of the entire processing step. The printing mechanism is located between the unwinding assembly and the hot stamping assembly. The printed material is fed out from the unwinding assembly, passes around the guide roller assembly, and then has a pattern printed on it by the printing mechanism at the printing station. It then enters the hot stamping station where the hot stamping assembly transfers the metallic pattern coating from the hot stamping film onto the printed material. Finally, the rewinding assembly collects the hot-stamped printed material. The printing mechanism is located between the unwinding assembly and the hot stamping assembly.

[0015] Furthermore, the printing mechanism is a digital printing system, which has multiple inkjet printheads.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application adds a film reuse adjustment component to the existing hot stamping production line. After the hot stamping film is hot stamped once, the metal pattern coating on the hot stamping film is transferred to the printed material. There will still be un-hot stamped metal pattern coating on the hot stamping film. This application changes the conveying path of the hot stamping film after the first hot stamping by changing the film reuse adjustment component, and hot stamps the un-hot stamped metal pattern coating, avoiding hot stamping film waste, saving costs, and eliminating the need for machine downtime, thereby improving hot stamping efficiency and film utilization.

[0017] 2. This application designs the structure of the membrane reuse adjustment component. It designs multiple membrane-passing rollers to turn and transport the original membrane material. At the same time, it adjusts the lateral position of the metal pattern coating on the membrane material by tilting the turning roller, and then adjusts the longitudinal position of the metal pattern coating on the membrane material by adjusting the adjustment roller. This achieves the positioning of the metal pattern coating on the membrane material during the transfer, ensuring that the graphic information is accurately transferred to the hot-pressed item.

[0018] 3. This application, through the design of the first sliding mechanism and the second sliding mechanism, can adjust the position of the hot stamping film material by a large margin, and is suitable for use in batches and large-format printed materials.

[0019] 4. This application allows users to flexibly configure the equipment according to production volume and functional requirements, making the overall structure of the equipment more compact, the coordination between functional modules higher, reducing the overall size and floor space, while improving the scalability and maintenance convenience of the equipment, thereby further improving the efficiency of waste film reuse and hot stamping.

[0020] 5. To further accelerate the hot stamping bonding effect, it is preferable to add a UV curing lamp to cure the already bonded metal pattern plating layer and the printed material, so as to facilitate continuous hot stamping in the next work station. Attached Figure Description
