SUMMARY

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:
[0017] like Figure 1 The heat transfer tactile patterned film shown includes a base layer 1, a release layer 2, a patterned layer 3, an elastic support layer 5, and an adhesive layer 7. The base layer 1 and the patterned layer 3 are respectively connected to the two surfaces of the release layer 2. The adhesive layer 7 is disposed at the bottom of the patterned layer 3. The elastic support layer 5 is disposed between the patterned layer 3 and the adhesive layer 7, and the elastic support layer 5 is configured with a wavy structure. The gap formed between the elastic support layer 5, the patterned layer 3, and the adhesive layer 7 is filled with a filler 6.
[0018] With the increasing demand for product personalization and high quality in industrial and consumer markets, heat transfer technology has been widely used in many fields. However, traditional heat transfer films often have certain limitations in terms of pattern effects and structural stability. The thickness and texture of the transferred pattern are difficult to adjust, especially when dealing with surfaces with a three-dimensional feel or different textures. The thickness of the film layer cannot be flexibly controlled, which restricts the tactile effect of the product. In addition, most traditional heat transfer films use a single thin film material, which cannot meet more complex functional requirements in some applications, especially for products that require high structural strength and elastic support.
[0019] In this solution, the base layer 1 provides support and stability for the film, ensuring that the shape and structure of the entire film will not be excessively deformed during the heat transfer process. The release layer 2 is set to prevent the film from sticking to the transfer surface, ensuring that the transfer process is completed smoothly and can be easily peeled off. The pattern layer 3 carries the transferred pattern or text, and the design pattern is transferred to the surface of the target object through hot pressing. The elastic support layer 5 provides support and elasticity for the film through a wave-shaped structure design, and can adjust the thickness of the film according to the temperature and pressure changes during the hot pressing process. The wave-shaped structure allows the film to produce adjustable shape changes during compression, thereby affecting the three-dimensional effect and overall thickness of the pattern layer 3. The function of the elastic support layer 5 is to ensure that the film is firmly attached to the surface of the target object during the transfer process.
[0020] The film is heated by a heat transfer device, causing the filler 6 in the elastic support layer 5 to gradually melt. The melted filler 6 can flow at high temperature and fill the gaps in the elastic support layer 5. Under pressure, the elastic support layer 5 is compressed, resulting in the filler 6 being evenly distributed and the upper and lower layers of the elastic support layer 5 being bonded together. By adjusting the temperature and pressure of the hot press, the thickness and elasticity of the corrugated layer can be precisely controlled, thereby achieving overall film thickness adjustment. After the heat transfer process is completed, the filler 6 will harden rapidly when the film cools, fixing the shape of the elastic support layer 5 and stabilizing the film thickness and tactile effect.
[0021] Regarding the selection of filler material, materials with specific tactile properties can be used, such as soft hot melt adhesives, elastic polyurethane foams, or waxes. The properties of these fillers will directly affect the tactile effect of the final product. By selecting different filler materials and adjusting the degree of hot pressing, the tactile feel of the film can be flexibly adjusted to meet the needs of different products.
[0022] The height of the elastic support layer 5 is set between 0.2mm and 1.5mm.
[0023] Since the goal of this solution is to adjust the overall thickness of the pattern, the height of the elastic support layer 5 should be within a certain range. This allows for effective changes in the film thickness during hot pressing without being too high, which would result in an insufficiently refined pattern or loss of detail. Therefore, the height of the elastic layer is set between 0.2mm and 1.5mm.
[0024] The patterned layer 3 and the adhesive layer 7 are connected to an intermediate layer 4 at their closest ends, and the elastic support layer 5 is connected between the pair of intermediate layers 4.
[0025] In this design, the intermediate layer 4 is made of a flexible material, which allows it to follow the compression of the elastic support layer 5. The filler 6 can be used to seal the edge of the elastic support layer 5, preventing the filler 6 from overflowing outside the membrane during the hot pressing process.
[0026] like Figures 1-2 As shown, a sealing strip 8 is connected between a pair of intermediate layers 4. The sealing strip 8 is arranged around the edge of the intermediate layer 4, and the elastic support layer 5 is connected to the inner wall of the intermediate layer 4.
[0027] In this solution, to prevent the elastic support layer 5 from deforming unstablely during hot pressing, an intermediate layer 4 is added above and below the elastic support layer 5 to enhance its rigidity and stability. The intermediate layer 4 can be made of polyester film, which has high stability, compressive strength and heat resistance. It can effectively support the structure of the elastic support layer 5, prevent unnecessary deformation of the elastic support layer 5, and provide stable heat conduction performance to help control the temperature during hot pressing. This ensures that each layer is heated evenly during the heat transfer process and avoids inconsistent release layer 2 or damage to the elastic support layer 5 due to local overheating or uneven pressure.
[0028] Multiple heat-conducting strips 9 are embedded and connected on the elastic support layer 5 in an equidistant arrangement, and the outer surfaces of the heat-conducting strips 9 extend to the outer sides of the two surfaces of the elastic support layer 5 respectively.
[0029] In this solution, the heat-conducting strip 9 can serve as a heat-conducting channel for heat transfer, which can accelerate the uniform distribution of heat in the elastic support layer 5. By setting the heat-conducting strip 9, it can be ensured that the filler 6 is heated to the melting temperature quickly and evenly, which is very beneficial to improving the fluidity and uniformity of the filler 6 and avoiding uneven hardening caused by local overheating or overcooling.
[0030] The specific implementation process is as follows:
[0031] First, a heat transfer film is prepared, which consists of a base layer 1, a release layer 2, a patterned layer 3, an elastic support layer 5, and an adhesive layer 7. Multiple heat-conducting strips 9 are installed inside the elastic support layer 5 to improve heat conduction efficiency. The gaps in the elastic support layer 5 are filled with filler 6. Then, the film is placed in a heat transfer machine and brought into contact with the target object. Through heating and pressurization, the heat transfer machine rapidly melts the filler 6 and distributes it evenly within the elastic support layer 5. The heat-conducting strips 9 ensure uniform heat transfer, thereby controlling the melting speed and pressure distribution of the filler 6. As temperature and pressure change, the thickness of the elastic support layer 5 is precisely adjusted, ultimately achieving the transfer and hardening of the film. After cooling, the filler 6 hardens and fixes the film's shape, ensuring stable film thickness, pattern effect, and tactile feel, thus completing the entire heat transfer process.
