Description

Technical Field

[0001] This utility model relates to the field of heat transfer film technology, specifically a heat transfer film that is not easy to fade. Background Technology

[0002] As a crucial consumable in the modern printing industry, the quality of heat transfer film's storage directly impacts subsequent transfer effects and finished product quality. Currently, the industry commonly employs roll-based storage, where the film material is wound onto a rigid core to form standard rolls. This storage method saves storage space and facilitates transportation and retrieval management. Proper roll-based storage requires maintaining a constant temperature and humidity environment and employing a professional shelving management system to ensure the film material retains stable physicochemical properties during storage.

[0003] Current thermal transfer film storage systems suffer from significant quality risks: First, traditional storage environments lack precise temperature and humidity control, making the film rolls prone to absorbing moisture from the air during storage, leading to frequent dampness. Second, damp film materials will generate gas due to moisture evaporation during the high-temperature transfer process, triggering a chain reaction of chemical reactions such as the oxidation and decomposition of colorants. Furthermore, these chemical changes can disrupt the molecular structural stability of the release layer, resulting in defects such as color differences and smudging in the transferred pattern. These quality issues not only affect the product's aesthetics but also increase the scrap rate. Therefore, we propose a thermal transfer film that is resistant to fading. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a heat transfer film that is not easy to fade. It can effectively prevent the transfer film roll from getting damp, thereby preventing it from fading during use, and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat transfer film that is not easily faded, comprising a mounting plate and a sealing assembly; Mounting plate: A protective tube is fixed at the front end, and a transfer film assembly and a drying assembly are installed inside the protective tube, and the transfer film assembly and the drying assembly cooperate with each other; Sealing assembly: includes a sealing arc plate, an arc-shaped iron plate, a magnetic strip, and springs. A strip-shaped opening is provided at the left end of the surface of the protective tube. Sliding grooves are provided on both the upper and lower sides of the strip-shaped opening. The sealing arc plate is slidably connected inside the sliding groove. An arc-shaped iron plate and two corresponding springs are fixed to the side of the sealing arc plate. Both springs are fixed inside the sliding groove. A magnetic strip is fixed inside the sliding groove. The magnetic strip corresponds to the arc-shaped iron plate. The strip-shaped opening is sealed by setting two sealing arc plates.

[0006] Furthermore, the transfer film assembly includes a storage rod, a transfer film roll, and a sealing cap. The storage rod is rotatably connected to the front end of the mounting plate. The transfer film roll is wound around the surface of the storage rod. The sealing cap is threaded to the front end of the surface of the storage rod. The sealing cap fits into the front end of the protective tube, thereby sealing the front port of the protective tube.

[0007] Furthermore, the drying assembly includes arc-shaped strips, arc-shaped mesh plates, calcium chloride, and a lifting groove. Two corresponding arc-shaped strips are fixed at both the upper and lower ends inside the protective tube. Arc-shaped mesh plates are slidably connected in the gap between the two arc-shaped strips and the protective tube. A storage groove is formed on the surface of the arc-shaped mesh plate, and the inside of the storage groove is filled with uniformly distributed calcium chloride. A lifting groove is formed on the front side of the arc-shaped mesh plate. By setting up the drying assembly, the inside of the protective tube can be effectively kept dry.

[0008] Furthermore, a limiting ring is fixed to the rear end of the surface of the storage rod, and the front end of the limiting ring is in contact with the rear end of the transfer film roll, thereby supporting the transfer film roll by setting the limiting ring.

[0009] Furthermore, the protective tube has two corresponding openings on its surface, and pull plates are installed inside the openings. The two pull plates are fixed to the sides of the two sealing arc plates respectively, so that users can easily pull the sealing arc plates to move them.

[0010] Compared with the prior art, the beneficial effects of this utility model are: this heat transfer film that is not easy to fade has the following advantages: 1. By leveraging the mutual attraction between the magnetic strip and the arc-shaped iron plate in the sealing assembly, combined with the continuous pressure provided by the spring, a double seal is achieved at the opening of the protective tube strip, effectively preventing the intrusion of external moisture. This ensures the airtightness of the storage environment for the transfer film roll from a physical structure perspective, thereby fundamentally avoiding problems such as moisture absorption and subsequent fading of the film material caused by environmental humidity.

[0011] 2. The curved mesh plate with sliding connection and filled with calcium chloride desiccant not only effectively adsorbs residual moisture inside the protective tube and keeps the air dry, but also allows users to regularly replace or maintain the desiccant through the lifting groove, which greatly improves the maintainability and long-term reliability of the product and extends the effective shelf life of the heat transfer film.

A transfer film assembly 4 and a drying assembly 5 are installed inside the protective tube 2. The transfer film assembly 4 and the drying assembly 5 cooperate with each other. The transfer film assembly 4 includes a storage rod 41, a transfer film roll 42, and a sealing cap 43. The storage rod 41 is rotatably connected to the front end of the mounting tray 1. The transfer film roll 42 is wound around the surface of the storage rod 41. The sealing cap 43 is threaded to the front end of the surface of the storage rod 41 and fits against the front end of the protective tube 2. The drying assembly 5 includes an arc-shaped strip 51 and an arc-shaped mesh plate 5. 2. Calcium chloride 53 and lifting trough 54. Two corresponding arc-shaped strips 51 are fixed at both the upper and lower ends inside the protective tube 2. An arc-shaped mesh plate 52 is slidably connected in the gap between the two arc-shaped strips 51 and the protective tube 2. A storage tank is opened on the surface of the arc-shaped mesh plate 52. The storage tank is filled with uniformly distributed calcium chloride 53. A lifting trough 54 is opened on the front side of the arc-shaped mesh plate 52. The drying component 5 can effectively ensure that the inside of the protective tube 2 is dry. The front port of the protective tube 2 is sealed by the sealing cover 43. Sealing assembly 3 includes a sealing arc plate 31, an arc iron plate 32, a magnetic strip 33, and a spring 34. A strip-shaped opening is provided at the left end of the surface of the protective tube 2. Slide grooves are provided on both the upper and lower sides inside the strip-shaped opening. The sealing arc plate 31 is slidably connected inside the slide groove. The arc iron plate 32 and two corresponding springs 34 are fixed on the side of the sealing arc plate 31. Both springs 34 are fixed inside the slide groove. The magnetic strip 33 is fixed inside the slide groove. The magnetic strip 33 corresponds to the arc iron plate 32. The strip-shaped opening is sealed by setting two sealing arc plates 31.

[0016] Wherein: a limiting ring 6 is fixed to the rear end of the surface of the storage rod 41, and the front end of the limiting ring 6 is in contact with the rear end of the transfer film roll 42, so that the transfer film roll 42 is supported by the limiting ring 6.

[0017] Among them, the protective tube 2 has two corresponding openings 7 on its surface, and a pull plate 8 is provided inside the opening 7. The two pull plates 8 are fixed on the sides of the two sealing arc plates 31 respectively. The pull plates 8 make it convenient for users to pull the sealing arc plates 31 to move.

[0018] The working principle of the fade-resistant heat transfer film provided by this utility model is as follows: During use, the user pulls the arc-shaped mesh plate 52 out of the protective tube 2 through the lifting groove 54 and adds calcium chloride 53 desiccant to its storage tank. Then, the user pushes it back to its original position limited by the arc-shaped strip 51. After desiccant maintenance, the user holds the pull plate 8 and pulls it outwards, causing the sealing arc-shaped plate 31 to overcome the elastic force of the spring 34 and slide within the groove. This allows the arc-shaped iron plate 32 on its side to adhere to the magnetic strip 33 fixed within the groove. The slot opens, allowing the user to pull out the transfer film roll 42 for use. When storing, the slot is resealed. After sealing, the calcium chloride 53 in the arc-shaped screen 52 continuously absorbs moisture from the internal environment of the protective tube 2, effectively keeping it dry and preventing the transfer film roll 42 from getting damp. This avoids problems such as colorant oxidation and decomposition and release layer instability caused by moisture evaporation during subsequent high-temperature transfer, ultimately preventing color difference, smudging, or fading of the transferred pattern.
