[0026] According to an embodiment of the present invention, an energy-saving heating coating device for artificial leather is provided.

[0027] Please refer to the instruction manual appendix. Figure 1-5 According to an embodiment of the present invention, an energy-saving heating coating device for artificial leather includes a housing 1. A front cover 2 is rotatably mounted on the front end of the housing 1. A feeding roller 4 is rotatably mounted on the lower left corner of the inner side of the housing 1. Artificial leather 5 is mounted on the outer side of the feeding roller 4. A tension roller adjusting mechanism 8 is fixedly mounted on the left inner side of the housing 1. An auxiliary roller 6 is mounted on the upper inner side of the tension roller adjusting mechanism 8. A tension roller 7 is mounted on the lower inner side of the tension roller adjusting mechanism 8. A receiving roller 9 is rotatably mounted on the right outer side of the housing 1. A multi-hole spray box 10 is provided at the upper and lower ends of the artificial leather 5 located on the right end. A spray box adjusting mechanism 12 is mounted on the front end of the multi-hole spray box 10. Infrared radiation tubes 11 are provided on the upper and lower sides of the artificial leather 5.

[0028] Compared to traditional heating methods, infrared heating technology can significantly reduce energy consumption. A precise control system can improve coating speed and shorten the production cycle. Uniform coating and heating can improve the surface quality and durability of artificial leather. The multi-hole nozzle design reduces paint waste and lowers production costs. The coating head uses a 5mm diameter multi-hole nozzle with a hole diameter of 0.5mm and a hole spacing of 2mm. The heating device uses an infrared heater with a power of 2kW and a heating range of 100cm x 100cm. The control system adopts a PLC control system, which can realize real-time monitoring and adjustment of temperature and speed.

[0029] Infrared radiation is a form of heat transfer, using electromagnetic waves to transfer energy. When far-infrared rays irradiate an object being heated, some rays are reflected back, while others penetrate. When the wavelength of the emitted far-infrared rays matches the absorption wavelength of the object being heated, the object absorbs the far-infrared rays. At this point, the molecules and atoms inside the object resonate—producing strong vibrations and rotations. These vibrations and rotations raise the object's temperature, thus achieving the heating effect.

[0030] Infrared drying and heating methods have seen remarkable growth and application across various fields in recent years, primarily due to the following advantages: 1. Penetrating power, enabling simultaneous internal and external heating. 2. No heat transfer medium required, resulting in excellent thermal efficiency. 3. Localized heating, saving energy. 4. Providing a comfortable working environment. 5. Saving on furnace construction costs and space; simple and easy assembly, installation, and maintenance. 6. Clean heating process, requiring no hot air and causing no secondary pollution. 7. Easy temperature control, rapid heating, and relatively high safety. 8. Low thermal inertia, eliminating the need for warm-up, saving manpower.

[0031] In one embodiment, please refer to the appendix to the specification. Figure 1-5 As a further embodiment of this utility model, a hinge is installed at the upper connection between the front cover 2 and the housing 1, and an observation window 3 is installed inside the front cover 2.

[0032] This facilitates observation of the equipment and ensures a dust-free production process.

[0033] Please refer to the appendix of the specification for another embodiment. Figure 1-5 As a further embodiment of this utility model, the tension roller adjusting mechanism 8 includes a fixing member 81, a connecting rod 82 fixedly connected to the outer side of the fixing member 81, an auxiliary roller 6 rotatably connected to the connecting rod 82, a lead screw 85 rotatably mounted on the inner side of the fixing member 81, a lead screw sleeve 84 helically connected to the outer side of the lead screw 85, a lead screw sleeve 84 rotatably connected to the tension roller 7, a handwheel 83 fixedly connected to the bottom end of the lead screw 85, and a sliding rod 86 slidably mounted on the inner side of the lead screw sleeve 84.

[0034] The tension roller 7 can be precisely raised and lowered by the tension roller adjustment mechanism 8, thereby tightening the artificial leather.

[0035] In one embodiment, please refer to the appendix to the specification. Figure 1-5 As a further embodiment of this utility model, the front ends of both the feeding roller 4 and the receiving roller 9 are equipped with worm gear and worm wheel drive mechanisms.

[0036] This ensures that the feeding roller 4 and the receiving roller 9 maintain the positioning of the artificial leather without power drive, preventing them from becoming loose.

[0037] Please refer to the appendix of the specification for another embodiment. Figure 1-5As a further embodiment of this utility model, the spray box adjustment mechanism 12 includes a threaded rod 121, a threaded sleeve 122 is helically connected to the outer side of the threaded rod 121, the threaded sleeve 122 is fixedly connected to the multi-hole spray box 10, a round rod 124 is slidably installed on the inner side of the threaded sleeve 122, a knob 123 is fixedly connected to the bottom end of the threaded rod 121, and the threaded rod 121 is provided with opposite threads, which are arranged symmetrically up and down.

[0038] The spray box adjustment mechanism 12 allows the multi-hole spray box 10 to be adjusted relative to each other, so that the coating head and the artificial leather maintain a precise distance, and the artificial leather can be coated on both sides or one side.

[0039] In use, the artificial leather roll material is installed on the feeding roller 4, and then the artificial leather is sequentially threaded onto each roller. Finally, the tail of the artificial leather is fixed to the receiving roller 9. Driven by the drive motor, the worm gear drives the feeding roller 4 and the receiving roller 9 to rotate, achieving stable conveying of the artificial leather 5. By turning the handwheel 83, the lead screw 84 is rotated, which in turn drives the lead screw sleeve 84 to move. The lead screw sleeve 84 drives the tension roller 7 to rise and fall, thereby tautning the artificial leather. Turning the knob 123 drives the threaded rod 121 to rotate, which in turn drives the multi-hole spray box 10 to move up and down relative to adjust the coating. The distance between the fabric and the artificial leather 5 is adjusted, and the multi-hole spray box 10 and infrared radiation tube 11 are opened to allow the artificial leather to complete coating and heating. Compared with traditional heating methods, infrared heating technology can significantly reduce energy consumption. The precise control system can improve coating speed and shorten the production cycle. Uniform coating and heating can improve the surface quality and durability of artificial leather. The multi-hole nozzle design reduces paint waste and lowers production costs. The coating head is a multi-hole nozzle with a diameter of 5mm, an orifice diameter of 0.5mm, and an orifice spacing of 2mm. The heating device uses an infrared heater with a power of 2kW and a heating range of 100cm x 100cm. The control system adopts a PLC control system, which can realize real-time monitoring and adjustment of temperature and speed.

[0040] Infrared heat transfer is radiative heat transfer, with energy transferred via electromagnetic waves. When far-infrared rays irradiate an object being heated, some rays are reflected back, while others penetrate. When the wavelength of the emitted far-infrared rays matches the absorption wavelength of the object being heated, the object absorbs the far-infrared rays. At this point, the molecules and atoms inside the object resonate—generating strong vibrations and rotations. These vibrations and rotations raise the object's temperature, achieving the heating purpose. Infrared drying heating has seen remarkable growth in recent years, gaining acceptance and application in various fields. This is primarily due to the following advantages: 1. Penetrating power, enabling simultaneous internal and external heating. 2. No heat transfer medium required, resulting in high thermal efficiency. 3. Localized heating, saving energy. 4. Providing a comfortable working environment. 5. Saving on furnace construction costs and space; simple assembly, installation, and maintenance. 6. Clean heating process, requiring no hot air and causing no secondary pollution. 7. Easy temperature control, rapid heating, and relatively high safety. 8. Low thermal inertia, eliminating the need for warm-up, saving manpower.
