Abstract
Description
Technical Field
[0001] The invention relates to the technical field of thermal transfer, and in particular to a flexible heating plate used for thermal transfer. Background Art
[0002] Existing thermal transfer technology has some limitations, especially in the design of the heating plate. Traditional heating plates are usually rigid structures, requiring the flatness of the hot stamping surface and the workbench to be high. If the surface is uneven, it is easy to cause uneven heating and affect the transfer effect. Therefore, the traditional process requires precision processing of the heating plate and the workbench, which increases the production difficulty and equipment cost. A flexible heating plate for thermal transfer is urgently needed to solve the above technical problems. Summary of the invention
[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a flexible heating plate for thermal transfer.
[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A flexible heating plate for thermal transfer comprises a heat-conducting aluminum plate, a heating pad, heat-insulating sponge and an inner shell are sequentially arranged on the top of the heat-conducting aluminum plate, a packaging sleeve is arranged on the bottom of the inner shell, the heat-conducting aluminum plate, the heating pad and heat-insulating sponge are all located inside the packaging sleeve, and an outer shell is arranged on the top of the inner shell.
[0005] Preferably, a plurality of fixing columns are arranged on the top of the heat-conducting aluminum plate, and a plurality of through holes whose opening positions correspond to the top positions of the fixing columns are opened on the heating pad, the heat-insulating sponge and the inner shell.
[0006] Preferably, a heat insulating gasket and a locking component are provided at one end of the fixing column extending through the through hole to the top of the inner shell.
[0007] Preferably, a plurality of connecting posts are arranged at intervals on the top of the packaging sleeve, and a plurality of connecting holes are provided around the inner shell with opening positions corresponding to the top positions of the connecting posts.
[0008] Preferably, a handle is mounted on the top of the housing via a handle fixing screw.
[0009] Preferably, a power cord outlet is provided on one side of the housing.
[0010] The beneficial effects of the present invention are: 1. Improve the uniformity of thermal transfer effect: Due to the design of the thermal conductive aluminum plate and heating pad, when subjected to pressure, the thermal insulation cotton and the silicone packaging sleeve are squeezed and deformed, so that the flexible heating plate can automatically adapt to and fit the uneven work surface, thereby ensuring a more uniform temperature distribution during the heating process, avoiding temperature control differences caused by uneven product or workbench surfaces, and improving the quality of thermal transfer.
[0011] 2. Energy saving and high efficiency: Using aviation aluminum with a thickness of less than or equal to 1mm as the heat-conducting aluminum plate, and equipped with a thin silicone layer and etched electric heating foil as the heating pad, it reduces heat loss and significantly improves the efficiency of heat conduction. The temperature rises quickly, from 20℃ to 180℃ in just 1 minute and 30 seconds, which reduces energy consumption during the heating process; through the design of rapid heating and cooling, it effectively reduces standby time and waiting time, optimizes production efficiency, and further saves energy consumption.
[0012] 3. Fast response and precise temperature control: The flexible heating plate of the present invention has an extremely fast temperature response speed, and the temperature change reaction time is only 1.5 seconds, which is significantly better than the response time of more than 5 seconds of the traditional process. This fast response can ensure accurate and timely temperature changes, avoiding the problems of overheating or unstable temperature control; the temperature uniformity is greatly improved, and the local temperature difference is only ±2.5℃, while the temperature difference of the traditional process can reach ±10℃, which significantly improves the product consistency and finished product quality.
[0013] 4. Improve production efficiency: The flexible heating plate of the present invention not only greatly improves the heating and cooling speeds (heating speed is 3-5 minutes faster, cooling speed is 10-15 minutes faster), but also can maintain a small temperature difference in the edge area (the temperature difference in the edge area is only ±2.5°C), which means that the temperature can be controlled more accurately during the thermal transfer process, reducing defective products and waste caused by uneven temperature control, and further improving production efficiency.
[0014] 5. Reduce production costs: The present invention reduces the weight of the overall equipment and reduces material and transportation costs by adopting thin and lightweight materials (such as aviation aluminum and silicone layers). At the same time, its efficient energy utilization and shorter heating and cooling time also reduce energy consumption in the production process, ultimately achieving a reduction in overall production costs.
[0015] 6. Simplified structure and convenient operation: Since the flexible heating plate can automatically adapt to the uneven surface of the workbench, its design simplifies the requirements for equipment flatness in the production process, making the operation more convenient, helping to reduce human errors and improve the level of automation and stability of production.
