Description

Technical Field

[0001] This utility model relates to the field of microfiber leather ironing technology, and in particular to a microfiber leather ironing device. Background Technology

[0002] Microfiber leather, a high-tech material that closely resembles natural leather in appearance, feel, and performance, is widely used in footwear, bags, furniture, and automotive interiors due to its advantages such as wear resistance, cold resistance, breathability, and environmental friendliness. In the production process of microfiber leather, ironing (or calendering) is a crucial post-processing step.

[0003] Traditional ironing equipment often uses a single static heating plate for pressing. When heat is transferred from the heating plate to the interior of the leather, uneven heat distribution can easily occur due to uneven contact, uneven pressure, or differences in the thickness of the leather itself. This can result in some areas being over-ironed (resulting in "shiny spots," thinning, and a hardened feel), while other areas are under-ironed (leaving wrinkles), severely impacting the consistency of the final product's quality and yield rate. Many small workshops or traditional production lines still rely on semi-manual or fully manual operation, such as manually placing the leather, manually controlling the ironing time, and manually removing parts. This model is not only labor-intensive but also has a slow production cycle, failing to meet the demands of modern large-scale, high-efficiency production. Although some simple conveyor-type ironing machines exist, their function is limited, only enabling linear material transport. Under high temperature and pressure, if the coating or fiber structure on the leather surface is not evenly heated and stretched, new indentations or "dead creases" can easily form under pressure. Especially after ironing, improper handling during the cooling process can lead to uneven stress release, causing the flatness to rebound and ruining the entire process. When microfiber leather is heated, trace amounts of residual moisture or additives inside will vaporize. If this moisture and hot air cannot be expelled from the ironed area in time, it will create an "air cushion" effect, hindering the effective transfer of heat to the leather surface. At the same time, a high temperature and high humidity environment may also have adverse effects on the leather surface, such as dull luster and a sticky feel.

[0004] To address the above problems, a microfiber leather ironing device needs to be designed to overcome them. Utility Model Content

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-4 As shown, a microfiber leather ironing device includes a preheating box 1 and a positioning frame 4, with a buffer auxiliary component provided on the inner side of the positioning frame 4. The buffer auxiliary component includes a conveyor belt 5 set on the inner side of the positioning frame 4 and connected to a drive shaft 6. A processing pad 10 is set on the top of the conveyor belt 5. Telescopic rods 8 are connected to both ends of the bottom of the processing pad 10. A buffer spring 9 is installed on the outer wall of the telescopic rods 8. Vent holes 11 are opened at both ends of the top of the processing pad 10. A drive motor 12 is set at one end of the positioning frame 4. A heater 13 is installed on the top of the positioning frame 4. A heating tube 2 is provided at one end of the preheating box 1, and an ironing board 3 is provided at the output end of the heating tube 2. The bottom of the ironing board 3 contacts the inner side of the processing mat 10. Both ends of the conveyor belt 5 are provided with drive shafts 6. The conveyor belt 5 is connected to the drive motor 12 through the drive shafts 6. The drive shafts 6 are rotatably connected to the positioning frame 4. The top of the conveyor belt 5 contacts the bottom of the telescopic rod 8. The top of the telescopic rod 8 is rotatably connected to the bottom of the processing mat 10. The telescopic rod 8 is fixedly connected to the buffer spring 9. The positioning frame 4 is fixedly connected to the heater 13. Specifically, in this embodiment, firstly, the main frame of the device, namely the positioning frame 4, is constructed. The positioning frame 4 is made of sturdy metal materials such as stainless steel or aluminum alloy profiles, welded or bolted together to ensure sufficient rigidity and stability to withstand the pressure and vibration during the ironing process. Inside the positioning frame 4, two parallel drive shafts 6 are installed on both sides via bearing seats. The conveyor belt 5, preferably made of high-temperature resistant and wear-resistant polytetrafluoroethylene fiberglass cloth or silicone belt, is fitted onto the two drive shafts 6, and its tension is adjusted. One of the drive shafts 6 is connected to the drive motor 12, preferably a variable frequency speed control motor, via a coupling or chain / belt drive. The drive motor 12 is fixed to the outside of the positioning frame 4, and its speed is adjustable to control the linear speed of the conveyor belt 5, thereby matching the ironing time required for different processes. A processing pad 10 is placed on the upper surface of the conveyor belt 5. The processing pad 10 should have a certain degree of hardness and heat resistance, and its upper surface should be flat to support the leather. The bottom ends of the processing pad 10 are rotatably connected to the top of the telescopic rod 8 via hinges or universal joints. This rotatable connection allows the processing pad 10 to freely make slight angle adjustments when under pressure, ensuring a perfect fit with the ironing board 3. The telescopic rod 8 passes through a pre-set through hole on the positioning frame 4, and a limiting plate is fixedly connected to its bottom. A buffer spring 9 is sleeved on the outer wall of the telescopic rod 8, with one end abutting against the crossbeam of the positioning frame 4 and the other end abutting against the limiting plate at the bottom of the telescopic rod 8. When the telescopic rod 8 moves downward, the buffer spring 9 is compressed, providing an upward elastic buffering force. Several vent holes 11 are symmetrically opened at both ends of the top surface of the processing pad 10. The diameter and distribution density of the vent holes 11 are optimized according to the amount of volatiles produced by the leather, ensuring smooth venting without affecting the flatness of the processing pad 10.

[0017] One end of the heater 13 is connected to an air supply pipe 14, and the end of the air supply pipe 14 away from the heater 13 is connected to a cavity buffer block 15. The top of the cavity buffer block 15 is connected to a support frame 16 through a connecting hose, and one end of the support frame 16 is connected to multiple air jets 17. The air supply pipe 14 is rotatably connected to the heater 13, the air supply pipe 14 is rotatably connected to the cavity buffer block 15, the cavity buffer block 15 is fixedly connected to the support frame 16, and the support frame 16 is fixedly connected to the jet nozzle 17 through the inner side connecting hose. Specifically, in this embodiment, a preheating box 1 is installed above the positioning frame 4. At least one heating tube 2 is fixedly installed inside the preheating box 1. The heating tube 2 is preferably an electric heating tube, and its power is selected according to production requirements. The bottom of the heating tube 2 is in close contact with the upper surface of the ironing board 3 to ensure that heat can be efficiently and evenly conducted to the ironing board 3. The ironing board 3 is made of a metal material with excellent thermal conductivity, such as copper or aluminum alloy, and its lower surface is precision polished to ensure that the leather surface is smooth and free of marks after ironing. A temperature controller and a temperature sensor (not shown in the figure) are also installed on the preheating box 1 to precisely control the working temperature of the ironing board 3. At the top of the positioning frame 4, downstream of the conveying direction (i.e., after the ironing board 3), a heater 13 is fixedly installed. The air outlet of the heater 13 is connected to one end of the air supply pipe 14 via a flange or quick connector. The air supply pipe 14 is made of a high-temperature resistant, heat-insulating flexible or rigid pipe. The other end of the air supply pipe 14 is connected to the air inlet of the cavity buffer block 15. The cavity buffer block 15 is a box structure with an internal cavity, which stabilizes and homogenizes the hot air flow from the heater 13. The air outlet of the cavity buffer block 15 is connected to the support frame 16 via a connecting hose. The support frame 16 spans across the conveyor belt 5 and has an airflow channel inside that communicates with the connecting hose. On the bottom surface of the support frame 16, multiple air jets 17 are evenly spaced along its length. The air jets 17 are directed towards the leather on the conveyor belt 5. Their design can be downward or tilted at a certain angle to form a uniform hot air curtain covering the entire width of the leather.

[0018] It should be noted that this utility model is a microfiber leather ironing device. When in use, the operator first turns on the power system of the entire device, and the drive motor 12 starts to run. Through the transmission shaft 6, the conveyor belt 5 starts to rotate at a preset constant speed. At the same time, the heating tube 2 in the preheating box 1 starts to be powered on and heated, so that the temperature of the ironing board 3 gradually rises and stabilizes at the set value required by the process, such as 80-150°C. The temperature is adjusted according to the leather material and thickness. The warm air blower 13 also starts to generate hot air. The operator places the microfiber leather to be processed flat on the processing pad 10 at the inlet end of the conveyor belt 5. As the conveyor belt 5 moves, the leather is steadily sent to the ironing station below the preheating box 1. When the processing mat 10 carrying the leather is conveyed directly below the ironing board 3, the ironing process officially begins. Under its own weight or external pressure, such as the push of a cylinder (not shown in the figure), the ironing board 3 presses down on the leather of the processing mat 10. At this time, the buffer auxiliary component located at the bottom of the processing mat 10 begins to play a key role: the downward pressure of the ironing board 3 is transmitted to the telescopic rods 8 at both ends through the processing mat 10. The telescopic rods 8 are subjected to a downward force and begin to compress the buffer springs 9 fixed to them. The compression process of the buffer springs 9 not only absorbs the impact and makes the pressure application more gentle, but more importantly, it forms a dynamic and adaptive floating support system. Regardless of the slight difference in leather thickness or the slight vibration of the conveyor belt 5 during operation, the buffer springs 9 can adjust the height of the telescopic rods 8 in real time to ensure that the ironing board 3 and the leather surface always maintain a uniform and stable contact pressure, avoiding ironing defects caused by uneven pressure. During the ironing process, the ironing board 3 continuously presses down, and the buffer spring 9 is in a continuous compressed state. Due to the continuous movement of the conveyor belt 5, the slight vibration of the transmission system, and the physical characteristics of the spring itself, the entire buffer auxiliary assembly processing pad 10, telescopic rod 8, and buffer spring 9 will generate a high-frequency, small-amplitude micro-vibration. This micro-vibration is transmitted to the processing pad 10 and the leather on it, playing two key roles: the micro-vibration energy helps the fiber structure inside the leather to better stretch in the softened state under heat, further eliminating fine wrinkles; after the leather is heated, the water vapor and hot air formed by the evaporation of residual moisture or auxiliaries inside the leather are "shaked" out under the action of vibration and quickly discharged through the exhaust hole 11 opened on the processing pad 10. This effectively avoids the "air cushion" effect formed by gas accumulation in the traditional process, ensuring that the heat can be efficiently and evenly transferred to every corner of the leather, thereby achieving a uniform and thorough ironing effect. After the leather is ironed, as the conveyor belt 5 continues to move forward, it leaves the direct heating zone of the ironing plate 3 and immediately enters the heat preservation and slow cooling zone constructed by the warm air blower 13 system. The constant temperature hot air generated by the warm air blower 13 is delivered to the cavity buffer block 15 through the air pipe 14. The cavity buffer block 15 plays a role in stabilizing the air pressure and equalizing the airflow. Subsequently, the hot air enters the support frame 16 through the connecting hose, and finally blows from top to bottom on the surface of the leather that has just been ironed in the form of a gentle and uniform airflow from multiple evenly distributed air jets 17 on the support frame 16.
