Technical Field

[0001] The utility model relates to the technical field of leather processing, in particular to a hot ironing machine for improving the brightness of leather. Background Art

[0002] Leather ironing machines are essential equipment in the leather processing and production process, primarily used to enhance the gloss and smoothness of leather surfaces. While leather surfaces retain a certain grain and gloss after physical and chemical processes such as dehairing and tanning, they still require post-finishing to further enhance their appearance. Ironing machines are crucial in this process. Under the rolling and pressure of the ironing rollers, the leather surface comes into close contact with the rollers and is subjected to high-temperature pressure, significantly enhancing the leather's surface gloss and smoothness, resulting in a more aesthetically pleasing and comfortable feel.

[0003] Existing leather ironing machines are somewhat effective in improving the gloss and smoothness of leather. However, their designs often overlook the importance of safety precautions, leading to potential burns and other safety hazards for workers during use. Since the ironing rollers must reach a high temperature to achieve the desired pressing effect, and the leather must maintain a certain speed and pressure as it passes through the ironing area, workers may accidentally come into contact with the hot rollers or related components during operation, potentially causing burns. Furthermore, some ironing machines lack emergency shutdown or protective isolation features, further increasing safety risks.

[0004] Therefore, there is an urgent need for a hot ironing machine with a safety protection structure for improving the brightness of leather. Utility Model Content

An infrared sensing device 13 is installed in the middle of the right side of the frame 1. The infrared sensing device 13 can detect whether there is a human body part approaching.

[0028] When the leather needs to be ironed, the leather in the placement frame 2 is slowly pushed between the ironing roller 5 and the guide roller 504, the motor 3 is started to drive the guide roller 504 to rotate and the ironing roller 5 is driven to rotate through the gear assembly 6, so that the leather passes through the rotating ironing roller 5 and the guide roller 504. At the same time, the heating device 9 heats the ironing roller 5, so that when the leather is subjected to pressure in a softened state, its surface is flattened, reducing unevenness, thereby improving smoothness and enhancing the brightness of the leather. When a person or hand approaches the ironing roller 5, the infrared sensing device 13 detects that burns may be caused, and the cylinder 4 is started to drive the pressing plate 401 to move downward along the second guide rod 404 to press the first baffle 7, so that the first baffle 7 moves downward and the first guide rod 402 slides down along the support plate 802. The first baffle 7 moves downward to press the first protective plate 8, so that the first protective plate 8 covers the ironing roller 5 to prevent people from contacting the ironing roller 5 and causing burns.

The support rod 10 is provided on the front side of the frame 1 to provide a certain supporting force for the leather, so that the leather can be pushed between the ironing roller 5 and the cloth guide roller 504 for ironing. The box 12 is provided with an arc-shaped second baffle 11.

[0031] When the leather to be ironed has different thicknesses, when the leather of different thicknesses passes between the ironing roller 5 and the guide roller 504, the connecting plates 501 on both sides of the ironing roller 5 can move up along the third guide rod 502, or reset under the action of the second spring 503, thereby automatically adjusting the position according to the thickness of the leather, ensuring that the appropriate contact pressure is maintained between the ironing roller 5 and the leather, and leather of different thicknesses can be ironed with appropriate pressure. Under appropriate pressure and temperature, the glossiness of the leather surface can be significantly improved. When the ironed leather needs to be collected, the handle 1201 is pulled out of the box 12, so that the ironed leather falls into the box 12 for collection under the restriction of the second baffle 11.
