Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to synthetic leather production technical field especially relates to a synthetic leather production drying equipment. BACKGROUND
[0002] In the coating making process of synthetic leather, solvent type polyurethane resin and other materials will be used, which contain a large amount of solvent and moisture. The main purpose of drying is to make the solvent and moisture fully volatilize through heating to ensure that the coating can be cured and firmly attached to the base cloth. During the drying process, appropriate temperature can promote the cross-linking reaction between the coating and the base cloth, which can enhance the adhesion between the coating and the base cloth, improve the overall strength and durability of the product, and improve the hand feeling, gloss and softness of synthetic leather. By controlling the drying temperature and time, the surface of synthetic leather can be made more smooth and comfortable.
[0003] The patent with publication date of January 23, 2024 and publication number CN220376989U discloses a synthetic leather production line drying equipment, which includes a dryer and a drying mechanism. The drying mechanism includes a first support frame, a first motor, a fan blade, an air inlet, a dustproof protective net, a placement frame, an electric heating wire, and a heat dissipation air exchange hole. The outer surface of the dryer is provided with a feeding port. The synthetic leather production line drying equipment blows the external wind from the air inlet into the dryer through the fan blade. The dust and impurities in the gas are prevented from entering the dryer through the air inlet by the dustproof protective net. The wind entering the dryer blows the electric heating wire, which changes the natural wind into hot wind, thereby drying the synthetic leather with hot air. The electric heating wire is distributed at equal intervals on the inner wall of the placement frame, which can increase the heat dissipation and discharge the heated air through the heat dissipation air exchange hole, thereby achieving the effect of air circulation and completing the drying of synthetic leather.
[0004] During the drying process, humidity is an important factor affecting the drying effect. During the drying process, the humidity in the drying chamber needs to be maintained within a suitable range to promote the rapid evaporation of moisture in synthetic leather. If the humidity is too high, it will prolong the drying time and increase the energy consumption. If the humidity is too low, it may cause the surface of synthetic leather to crack or deform. The above-mentioned scheme considers increasing the heating area of synthetic leather to enhance the drying efficiency, but does not consider controlling the humidity in the environment, which affects the drying effect of synthetic leather.
[0005] Therefore, it is necessary to provide a synthetic leather production drying equipment. UTILITY MODEL CONTENT

[0025] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application. The terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.
[0027] To address the problem of surface cracking and deformation of synthetic leather during the drying process due to insufficient control and adjustment of humidity in the drying environment, this application provides the following solutions.
[0028] Please refer to the following: Figures 1-4 The system includes a conveying mechanism 1, a drying mechanism 2, a control console 3, a placement box 4, a frame 5, a water tank 6, a water pump 7, a spray head 8, a connecting pipe 9, and a humidity sensor 10. The humidity sensor 10 and the conveying mechanism 1 are both mounted on the frame 5. The drying mechanism 2 is mounted on the conveying mechanism 1. A placement cavity is formed between the conveying mechanism 1 and the frame 5. The spray head 8 is fixedly connected to the placement cavity. The placement box 4 is welded to the frame 5. The water tank 6 and the control console 3 are both fixedly connected to the placement box 4. The water pump 7 is mounted on the water tank 6. One end of the connecting pipe 9 is mounted on the water pump 7, and the other end is threadedly connected to the spray head 8. The temperature sensor 28 and the water pump 7 are both electrically connected to the control console 3.
[0029] With this setup, the synthetic leather to be dried enters the drying mechanism 2 via the conveyor mechanism 1. The drying mechanism 2 evaporates the moisture and solvent in the synthetic leather coating, ensuring that the coating can be cured and firmly adhered to the base fabric. During the drying process, the humidity sensor 10 monitors the humidity in the drying mechanism 2 in real time and feeds the humidity back to the control console 3. When the humidity is not up to standard, the control console 3 controls the water pump 7 to draw water from the water tank 6 and transport the water to the spray head 8 through the connecting pipe 9. The spray head 8 sprays water in a rotating manner to form a water mist. A placement cavity is formed between the conveyor mechanism 1 and the frame 5. The spray head 8 is placed in the placement cavity. After the water mist is formed, it moves upward under the action of the airflow, which increases the humidity in the environment more quickly and maintains it within a suitable humidity range, avoiding problems such as cracking and deformation of the synthetic leather surface during the drying process. The connecting pipe 9 is threadedly connected to the spray head 8 to ensure that the water pressure will not wash away the spray head 8 when pumping water. The water tank 6 can be opened with a through hole to connect to the water supply valve to realize automatic water supply and ensure that there is always enough water in the water tank 6.
[0030] Optionally, in some embodiments, please also refer to Figure 1 as well as Figure 4 The conveying mechanism 1 includes a conveyor belt 11, a belt 12, a heat insulation plate 13, a rotating motor 14, and a transmission gear 15. The heat insulation plate 13 is fixedly connected to the frame 5. The frame 5 has a through hole. The transmission gear 15 is fixedly connected to the frame 5 through the through hole. The conveyor belt 11 is disposed on the transmission gear 15. The rotating motor 14 is disposed on the frame 5. The output end of the rotating motor 14 is connected to the transmission gear 15 through the belt 12. Dust baffles 16 are disposed around the rotating motor 14.
[0031] With this setup, the control console 3 controls the operation of the rotary motor 14. The output end of the rotary motor 14 is connected to the transmission gear 15 by a belt 12. Therefore, the rotary motor 14 and the transmission gear 15 move synchronously. The transmission gear 15 drives the conveyor belt 11 to move together, thus realizing the movement of the conveyor belt 11. This allows the leather to be dried to be transported to the drying mechanism 2. The rotation speed of the rotary motor 14 is proportional to the movement speed of the conveyor belt 11. The heat insulation plate 13 is used to isolate the frame 5 from the hot air, which reduces heat loss on the one hand and ensures the temperature stability of the frame 5 on the other hand, protecting the other heat-sensitive components on the frame 5.
[0032] Optionally, in some embodiments, please also refer to Figure 1 The conveyor belt 11 has multiple square ventilation holes.
[0033] With this configuration, the conveyor belt 11 is made of a material with high yield strength, high thermal conductivity, and low coefficient of thermal expansion. High yield strength means it is less prone to deformation or damage. High thermal conductivity means it can transfer heat to the synthetic leather on the placement tray more quickly, thereby improving heating efficiency and shortening drying time. High thermal conductivity also helps to achieve uniform temperature distribution in the oven, avoiding local overheating or underheating, ensuring consistent drying results and product quality. Low coefficient of thermal expansion means that its size changes relatively little when the temperature changes, protecting the structure of the placement tray from damage and extending its service life. Multiple square ventilation holes increase the contact area between the synthetic leather and the hot air, which helps to shorten drying time and save energy.
[0034] Optionally, in some embodiments, please also refer to Figure 1 as well as Figure 2 The drying mechanism 2 includes a drying chamber 21, a fan 22, an electric heating element 23, and a filter 26. The drying chamber 21 is mounted on the heat insulation plate 13, and an air inlet 24 is provided on the side of the drying chamber 21. The fan 22 is mounted on the drying chamber 21, and the center of the fan 22 coincides with the center of the air inlet 24. The filter 26 is mounted on the fan 22. The electric heating element 23 is located between the fan 22 and the conveyor belt 11. An air outlet 25 is provided at the upper end of the drying chamber 21. The fan 22 and the electric heating element 23 are electrically connected to the control console 3. An adjusting plate 27 is also rotatably connected to the drying chamber 21 and is located in the air outlet 25.
[0035] With this configuration, a filter 26 is installed at the air inlet 24. The filter 26 can effectively block dust, hair, insects and other impurities in the air from entering the equipment, reducing dust accumulation and pollution inside the equipment, thereby protecting the normal operation of the equipment and extending its service life. The electric heating tube 23 generates heat through electric current, and the fan 22 circulates the heated dry air into the drying chamber 21, causing a large amount of solvent and moisture contained in the coating on the surface of the synthetic leather to evaporate. The air inlet 24 is located on the side of the drying chamber 21, which can ensure that the air can be evenly distributed to the surface of the material. The air outlet 25 is located above the drying chamber 21, which uses the principle of hot air rising to help effectively remove moisture. The cross-sectional area of the air outlet 25 is larger than that of the air inlet 24. The regulating plate 27 on the air outlet 25 can realize the control of air volume and air pressure to avoid unnecessary energy waste. By balancing the air pressure, the regulating plate 27 can also optimize the overall performance of the system and improve ventilation efficiency or drying effect. For example, when the synthetic leather is about to dry, the air volume can be reduced to reduce energy consumption.
[0036] Optionally, in some embodiments, please also refer to Figure 1In some embodiments, the drying mechanism 2 further includes a temperature sensor 28, which is fixedly connected to the side of the drying chamber 21 away from the fan 22 and close to the conveyor belt 11. The temperature sensor 28 is electrically connected to the control console 3.
[0037] With this setup, the temperature sensor 28 is located close to the synthetic leather product on the conveyor belt 11, and the measured temperature is very close to the temperature of the hot air passing through the surface of the synthetic leather, making it more representative. The temperature sensor 28 can monitor the temperature inside the dryer in real time, ensuring that the temperature during the drying process remains within the set range. This is crucial for the drying effect, as excessively high or low temperatures may affect the drying effect or even damage the dried items. Through the temperature sensor 28, the control console 3 can automatically adjust parameters such as the power of the heating element 23, the speed of the fan 22, and the amount of water sprayed by the spray head 8 based on the real-time monitored temperature data to maintain the stability of the drying temperature. This automatic adjustment mechanism ensures a more uniform and efficient drying process.
[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
