[0023] A leather production method, comprising the leather production system; The leather production method comprises the following steps: Step S1, feeding drying: pre-treating the leather and cutting it into rectangular sheets, placing the sheets of leather on the feeding conveying assembly for conveying, the feeding conveying assembly conveys the leather to the drying conveying assembly, and then passes through the constant temperature conveying assembly, the cooling conveying assembly and the discharging conveying assembly in sequence, drying the leather when passing through the drying conveying assembly, subjecting the dried leather to a constant temperature transition when passing through the constant temperature conveying assembly, air cooling the leather when passing through the cooling conveying assembly, and finally conveying the leather toward the softening mechanism through the discharging conveying assembly; Step S2, conveying and softening: after the leather is dried and cooled, the leather is conveyed to the first softening conveying assembly through the discharging conveying assembly, and the first softening conveying assembly conveys the leather to the second softening conveying assembly, and the first softening driving assembly and the second softening driving assembly are both vibrators. When the leather is conveyed from the first softening conveying assembly to the second softening conveying assembly, the first softening driving assembly and the second softening driving assembly are vibrated by the vibrator, so that the hardened fibers of the leather after drying are softened; Step S3, transfer and lamination: after the leather is softened, the leather is transferred to a lamination mechanism, and the lamination mechanism laminarly ... Step S4, transfer and shaping: after the roller pressing and lamination is completed, the belt-shaped material with leather is transferred and transported by a transfer mechanism, and during the transportation process, the lamination side is blown and cooled to shape; Step S5, transfer needling: when the strip material enters the needling and pressing mechanism from the transfer mechanism, the two sides of the strip material are pressed and conveyed by the needling and pressing conveying assembly, and then the inner layer of the leather is needled by the needling and pressing mechanism to pierce the fiber web into the inner layer of the leather and pierce the membrane material at the same time, so that the leather can be breathable.

[0024] The beneficial effects of the present invention are: Compared with the existing leather preparation, the present invention closely connects the components from feeding drying to final piercing and pressing to form an efficient and continuous production line. The stacking arrangement of the feeding conveying component, drying conveying component, constant temperature conveying component, cooling conveying component and discharging conveying component not only optimizes the space utilization, but also ensures the stable conveying of the leather in the whole processing process, reduces manual intervention and improves production efficiency. The drying box combined with the drying and blowing component can adjust the appropriate wind speed and temperature according to the material and thickness of the leather to achieve precise drying. This design effectively avoids the quality problems of the leather caused by excessive or insufficient drying, such as cracking, deformation or excessive residual moisture, and ensures the best state of the leather in subsequent processing. The introduction of the cooling conveying component quickly reduces the temperature of the leather, prevents secondary deformation caused by high temperature, and is conducive to the subsequent softening treatment. The softening mechanism uses a specific process to make the leather reach the ideal softness and ductility, lays a good foundation for the subsequent pressing and piercing processes, and improves the comfort and durability of the leather products.

[0025] The pressing mechanism can press the fiber mesh evenly on the leather surface to enhance the strength of the leather. The piercing mechanism uses precise piercing action to make the fiber mesh penetrate into the leather to form a strong bond. This innovative technology not only improves the overall performance of the leather, but also gives the product a unique texture. The design of the transfer mechanism ensures the accurate transfer of leather between different processing stages and avoids processing defects caused by position deviation. Its efficient and stable operation provides strong support for the smooth operation of the entire production line. The present invention not only significantly improves the quality and efficiency of leather processing through efficient, precise and innovative process characteristics, but also reflects the emphasis on environmental protection and sustainable development. It is an important manifestation of technological progress in the leather manufacturing industry.

[0026] The softening mechanism adopts the design of double conveying components (i.e., the first softening conveying component and the second softening conveying component). This layout not only increases the contact area and path length of the leather during the softening process, but also realizes multi-angle and multi-level softening treatment of the leather through the relative staggered movement of the two components. This design effectively improves the softening efficiency, thereby achieving an ideal softening effect. At the same time, due to the staggered movement of the two conveying components, the leather is subjected to more uniform extrusion and friction during the conveying process, avoiding the uneven softening phenomenon that may occur under the traditional single conveying mode. The softening mechanism also fully considers the convenience of operation and the simplicity of maintenance. By articulating the opposite ends of the first softening conveying component and the second softening conveying component to the frame through the first articulated shaft and the second articulated shaft respectively, the entire mechanism is more compact and stable in structure. At the same time, this articulated design also facilitates the disassembly and replacement of the conveying component when necessary, reducing maintenance costs and time costs. In practical applications, the softening mechanism has shown excellent adaptability and flexibility. Whether it is leather of different thickness and material, or leather products with different softening requirements, the mechanism can achieve the best softening effect by adjusting the motion parameters of the conveying component and the control strategy of the drive component. This not only improves the quality and consistency of leather products, but also significantly improves production efficiency and economic benefits.

[0027] In the leather production method, in the feeding and drying stage of step S1, the uniformity and standardization of leather raw materials are ensured through pretreatment and precise cutting, laying a good foundation for subsequent processing. The integrated design of continuous conveying components (including drying, constant temperature, cooling and discharge conveying components) not only realizes the seamless connection from pretreatment to softening of leather, but also effectively avoids the internal stress of leather caused by rapid temperature changes through constant temperature transition and air cooling technology, ensuring the dimensional stability and uniformity of surface quality of leather. This step significantly improves the drying efficiency and quality control level of leather.

[0028] Entering the conveying and softening link of step S2, a vibrator is innovatively introduced as the driving source of the first and second softening and conveying components. The vibration not only promotes the loosening and rearrangement of the internal fibers of the leather, but also effectively softens the fiber structure hardened due to drying, creating more favorable conditions for the subsequent pressing process. This step greatly enhances the softness and comfort of the leather while maintaining the original toughness and durability of the leather.

[0029] In the transfer and lamination stage of step S3, the BOPE film, the plain fiber net and the inner layer of the leather are compositely connected by hot rolling technology, realizing the multi-layer structure integration of the leather. The high strength and toughness of the BOPE film, as well as the good air permeability and support of the plain fiber net, jointly improve the overall performance of the leather, such as enhancing the wear resistance, tear resistance and air permeability of the leather. The hot rolling process not only ensures the close adhesion between the layers, but also avoids damage caused by overheating of the leather through precise temperature control, maintaining the natural beauty of the leather.

[0030] In the transfer and shaping process of step S4, the shape of the composite leather is quickly fixed by the air cooling technology, thereby improving the dimensional stability and durability of the product. This step ensures that the leather is not easily deformed during subsequent processing and use, and maintains a good appearance and performance.

[0031] Finally, during the transfer needling process of step S5, the synergistic effect of the needling conveying assembly and the needling mechanism not only penetrates the fiber mesh deeply into the inner layer of the leather, but also penetrates the membrane material to form a microporous structure, which significantly improves the air permeability and comfort of the leather. This innovative process not only meets the high requirements of modern leather products for air permeability, but also gives the leather a more natural and comfortable feel. Through a series of finely designed steps, the present invention not only significantly improves the production efficiency and product quality of leather, but also gives the leather more superior physical properties and comfort, meeting the market's diversified demand for high-quality leather products.

Specifically, a constant temperature conveying gap is left between two adjacent constant temperature conveying components 24, two adjacent constant temperature conveying belts 242 are used to press and convey leather, and a constant temperature guide arc groove is left between the constant temperature conveying guide element 243 and the constant temperature conveying belt, and the constant temperature guide arc groove is used for leather conveying and guiding. A cooling and conveying gap is left between two adjacent cooling conveying components 31, two adjacent cooling conveying belts 312 are used to press and convey leather, and a cooling guide arc groove is left between the cooling conveying guide element 313 and the cooling conveying belt, and the cooling guide arc groove is used for leather conveying and guiding. In this embodiment, the drying and conveying gap left between two adjacent drying conveying components 23, and the corresponding drying conveying belts 232 and drying guide arc grooves are used to achieve effective drying and guiding of leather during the conveying process. This design not only improves the drying efficiency, but also ensures the stability and accuracy of the leather during the transportation process, avoiding deformation or damage of the leather due to improper transportation. Secondly, the design of the constant temperature conveying component 24 and the constant temperature conveyor belt 242 provides a stable temperature environment for the leather. Through the constant temperature guide arc groove left between the constant temperature conveying guide element 243 and the constant temperature conveyor belt, the leather can maintain a constant temperature during the transportation process, thereby further improving the quality and production efficiency of the leather. Finally, the design of the cooling conveying component 31 and the cooling conveyor belt 312 ensures the effective cooling of the leather during the transportation process. Through the cooling guide arc groove left between the cooling conveying guide element 313 and the cooling conveyor belt, the leather can be quickly cooled during the transportation process to achieve an ideal cooling effect.

[0041] The drying box 21 is provided with a door 213, a drying air outlet 214 is provided on one side of the drying box 21, a cooling air outlet 215 is provided on the rear side of the drying box 21, and the drying blowing assembly 25 is provided on the door 213 and is used to blow air toward the drying conveying assembly 23 to cooperate with the drying heating element 233 to perform hot air drying on the leather; the door 213 is provided with a cooling fan 216, and the cooling fan 216 is opposite to the cooling air outlet 215 to cool the leather; the door 213 is provided with a partition 2131, and one end of the partition 2131 extends to the inner side of the constant temperature conveying assembly 24 to separate the constant temperature conveying assembly 24 from the cooling conveying assembly 31. In this embodiment, the drying blowing assembly 25 is provided on the door 213, and can accurately blow air toward the leather on the drying conveying assembly 23, and cooperate with the built-in drying heating element 233 to achieve efficient hot air drying of the leather. This design not only ensures that the leather is evenly heated during the drying process, but also greatly shortens the drying cycle and improves production efficiency. Secondly, the cooling fan 216 equipped on the door 213 is opposite to the cooling exhaust port 215 on the rear side, forming an effective cooling channel. After the leather is dried, the cooling fan 216 can be started quickly to quickly cool the leather, avoiding deformation or damage to the leather due to long-term high temperature, thereby ensuring the quality of the finished leather. In addition, the design of the partition 2131 on the door 213 also plays a crucial role. One end of the partition 2131 extends to the inner side of the constant temperature conveying assembly 24, effectively separating the constant temperature conveying assembly 24 from the cooling conveying assembly 31, avoiding mutual influence between different temperature zones, and ensuring stable processing of the leather in each stage of constant temperature, drying and cooling.

[0042] See also Figure 5~Figure 6As shown, the softening mechanism 4 includes a first softening conveying component 41, a first softening drive component 42, a second softening conveying component 43 and a second softening drive component 44; the discharge end of the first softening conveying component 41 is opposite to the feed end of the second softening conveying component 43, the first softening conveying component 41 and the second softening conveying component 43 are provided with a first hinge shaft at one end opposite to the first softening conveying component 41, and the second softening conveying component 43 is provided with a second hinge shaft at one end opposite to the first softening conveying component 41, and is hinged to the frame 1, the first softening drive component 42 is arranged on the frame 1 and is used to drive the first softening conveying component 41 to move around the first hinge shaft, and the second softening drive component 44 is arranged on the frame 1 and is used to drive the second softening conveying component 43 to move around the second hinge shaft; when the leather enters the second softening conveying component 43 from the first softening conveying component 41, the first softening conveying component 41 and the second softening conveying component 43 are staggered at the opposite ends to soften the leather. In this embodiment, the softening mechanism 4 adopts a double conveying component design (i.e., a first softening conveying component 41 and a second softening conveying component 43). This layout not only increases the contact area and path length of the leather during the softening process, but also realizes multi-angle and multi-level softening treatment of the leather through the relative staggered movement of the two components. This design effectively improves the softening efficiency, thereby achieving an ideal softening effect. At the same time, due to the staggered movement of the two conveying components, the leather is subjected to more uniform extrusion and friction during the conveying process, avoiding the uneven softening phenomenon that may occur under the traditional single conveying mode. The softening mechanism 4 also fully considers the convenience of operation and the simplicity of maintenance. By respectively articulating the opposite ends of the first softening conveying component 41 and the second softening conveying component 43 to the frame 1 through the first hinge shaft and the second hinge shaft, the entire mechanism is more compact and stable in structure. At the same time, this articulated design also facilitates the disassembly and replacement of the conveying component when necessary, reducing maintenance costs and time costs. In practical applications, the softening mechanism 4 shows excellent adaptability and flexibility. Whether it is leather of different thickness and material, or leather products with different softening requirements, the mechanism can achieve the best softening effect by adjusting the motion parameters of the conveying component and the control strategy of the drive component. This not only improves the quality and consistency of leather products, but also significantly improves production efficiency and economic benefits.

[0043] The first softening conveying assembly 41 includes a first softening lower conveying frame 411 and a first softening upper conveying frame 412, a pressing conveying gap is formed between the first softening lower conveying frame 411 and the first softening upper conveying frame 412 for leather conveying, the first softening lower conveying frame 411 is connected to the first softening upper conveying frame 412, and the driving end of the first softening driving assembly 42 is connected to the first softening lower conveying frame 411. The second softening conveying assembly 43 includes a second softening lower conveying frame 431 and a second softening upper conveying frame 432, a pressing conveying gap is formed between the second softening lower conveying frame 431 and the second softening upper conveying frame 432 for leather conveying, the second softening lower conveying frame 431 is connected to the second softening upper conveying frame 432, and the driving end of the second softening driving assembly 44 is connected to the second softening lower conveying frame 431. The first softening upper conveying frame 412 is provided with a first softening roller 4121, and the second softening lower conveying frame 431 is provided with a second softening roller 4311, and the first softening roller 4121 is opposite to the second softening roller 4311, so as to guide the leather conveying; when the leather passes through the first softening roller 4121 and the second softening roller 4311, the first softening roller 4121 moves following the first softening conveying assembly 41, and the second softening roller 4311 moves following the second softening conveying assembly 43, so as to guide the leather to form an S shape. In this embodiment, through the synergistic effect of the first softening conveying assembly 41 and the second softening conveying assembly 43, the effective softening of the leather during the conveying process is achieved. Both conveying assemblies adopt a design of combining the lower conveying frame with the upper conveying frame, forming a pressing and conveying gap, which helps the leather to be subjected to uniform pressure during the conveying process, thereby improving the softening effect. Secondly, the first softening roller 4121 on the first softening upper conveying frame 412 and the second softening roller 4311 on the second softening lower conveying frame 431 are arranged opposite to each other, forming a precise guide for the conveying of leather. When the leather passes through these two rollers, the rollers can be flexibly adjusted following the movement of the conveying components, ensuring that the leather maintains a stable posture during the conveying process, avoiding damage to the leather caused by unstable conveying. In addition, the structure further enhances the softening effect by forming the leather into an S shape during the conveying process. The S-shaped conveying path allows the leather to be subjected to more friction and compression during the conveying process, which helps to soften the fibers inside the leather and improve the softness and comfort of the leather.

[0044] The first softening drive assembly 42 includes a first drive base 421, a first drive element 422 and a first hinge element 423, wherein the first drive base 421 is arranged on the frame 1, the first hinge element 423 is arranged on the first softening lower layer conveying frame 411, and the two ends of the first drive element 422 are respectively hinged to the first drive base 421 and the first hinge element 423. The second softening drive assembly 44 includes a second drive base 441, a second drive element 442 and a second hinge element 443, wherein the second drive base 441 is arranged on the frame 1, the second hinge element 443 is arranged on the second softening lower layer conveying frame 431, and the two ends of the second drive element 442 are respectively hinged to the second drive base 441 and the second hinge element 443. In this embodiment, the first drive base 421 and the second drive base 441 are respectively and firmly arranged on the frame 1, thereby ensuring the stability and reliability of the drive system. This design makes the driving process smoother, reduces the potential damage to the leather caused by mechanical vibration, and is conducive to maintaining the integrity and texture of the leather. Secondly, the first hinged element 423 and the second hinged element 443 are respectively connected to the first softening lower layer conveyor rack 411 and the second softening lower layer conveyor rack 431, realizing a flexible connection between the driving element and the conveyor rack. This articulation method enables the conveyor rack to adjust its angle and position as needed, so as to better adapt to various needs in the leather softening process and improve the uniformity and efficiency of softening. In addition, the two ends of the first driving element 422 and the second driving element 442 are respectively hinged to the corresponding base and the hinged element, forming a stable drive chain. This design not only simplifies the structure of the drive system and reduces maintenance costs, but also makes the driving process more accurate and controllable, which helps to achieve precise regulation of the leather softening process.

In this embodiment, by integrating the guide conveying component 51, the film material discharge component 52, the fiber web discharge component 53 and the hot roller pressing composite component 54, the leather, the film material and the fiber web are efficiently and accurately composited. The guide conveying component 51 ensures the stable conveying of the leather during the lamination process, effectively avoids problems such as material deviation or wrinkles, and lays a solid foundation for subsequent composite operations. The film material discharge component 52 and the fiber web discharge component 53 can accurately control the placement and amount of the film material and the fiber web, ensuring the uniformity and consistency of the composite material. The hot roller pressing composite component 54, as the core component of the lamination mechanism 5, realizes the effective rolling composite of the leather, the film material and the fiber web through the close cooperation of the upper roller body 541 and the lower roller body 542. The roller pressing heating element 543 built into the lower roller body 542 can quickly heat-melt the film material during the lamination process, so that the fiber web and the leather form a strong bond, thereby significantly improving the overall strength and durability of the composite material.

[0046] One end of the guide conveying assembly 51 is close to the second softening conveying assembly 43, and the other end is close to the upper roller body 541; the film material unwinding assembly 52 includes a film material unwinding roller 521 and a film material guide roller 522, and the film material guide roller 522 is used to guide the film material toward the hot rolling composite assembly 54; the fiber web unwinding assembly 53 includes a fiber web unwinding roller 531 and a fiber web guide roller 532, and the fiber web guide roller 532 is used to guide the fiber web toward the hot rolling composite assembly 54.

This design not only optimizes the production process, but also improves production efficiency. The film material unwinding assembly 52 can stably convey the film material to the hot rolling composite assembly 54 through the synergistic effect of the film material unwinding roller 521 and the film material guide roller 522. The guiding function of the film material guide roller 522 ensures the accurate position of the film material, thereby avoiding deviation or waste in the production process. This not only improves the efficiency of film material use, but also ensures the quality of leather products. The fiber web unwinding component 53 also adopts a combination of unwinding rollers and guide rollers to ensure stable transportation and accurate guidance of the fiber web.

In this embodiment, the two groups of transfer conveying components 61 arranged opposite to each other realize the stable and continuous conveying of leather on the production line. This design not only ensures the stability of the leather during the conveying process, but also effectively avoids the damage or deformation of the leather caused by improper conveying. It is particularly critical that the transfer shaping fan 62 arranged below the transfer conveying component 61 plays a vital role in the cooling and shaping of the leather. The fan blows air toward the conveying gap, which can quickly take away the heat on the surface of the leather and accelerate its cooling process. At the same time, the force of blowing air also helps the leather to maintain a certain tension in the conveying gap, thereby achieving a more accurate shaping effect. In addition, the conveying gap reserved between the two groups of transfer conveying components 61 not only provides sufficient blowing space for the fan, but also ensures that the leather can maintain appropriate air permeability during the cooling and shaping process. This design helps to discharge moisture from the leather, further improving the drying speed and shaping quality of the leather.

[0048] The piercing and pressing mechanism 7 comprises a piercing and pressing conveying assembly 71, a pressing assembly 72, a piercing and pressing drive assembly 73 and a piercing and pressing needle plate 74, one end of the piercing and pressing conveying assembly 71 is docked with the transfer conveying assembly 61, the pressing assembly 72 comprises a piercing and pressing pressing plate 721 and a pressing driving module 722, the piercing and pressing needle plate 74 is arranged on the piercing and pressing drive assembly 73, the piercing and pressing drive assembly 73 is used to drive the piercing and pressing needle plate 74 to move relatively towards the piercing and pressing pressing plate 721, the pressing driving module 722 is used to drive the piercing and pressing pressing plate 721 to move relatively towards the piercing and pressing needle plate 74, the piercing and pressing needle plate 74 is used to cooperate with the piercing and pressing pressing plate 721 to acupuncture one side of the leather, so as to pierce the film material and pierce the fiber web into the leather inner layer. In the present embodiment, the seamless docking of the piercing and pressing conveying assembly 71 and the transfer conveying assembly 61 ensures the stable transmission of the leather during processing, and avoids the processing error caused by poor transmission. At the same time, this design also improves the automation level of the production line and reduces the complexity of manual operation. Secondly, the pressing assembly 72 achieves a tight fixation of the leather through the synergistic effect of the piercing pressing plate 721 and the pressing drive module 722. This not only ensures the stability of the acupuncture process, but also effectively prevents the displacement or deformation of the leather during the processing, thereby improving the processing accuracy of the product. Furthermore, the piercing drive assembly 73 drives the piercing needle plate 74 to move relative to the piercing pressing plate 721, and with the tight acupuncture action, it can accurately pierce the membrane material and pierce the fiber mesh into the inner layer of the leather. This process not only enhances the bonding force between the leather and the membrane material, but also gives the leather a richer texture and texture.

[0049] See also Figure 1 to Figure 9 As shown, a leather production method comprises the leather production system; The leather production method comprises the following steps: Step S1, feeding drying: pre-treating the leather and cutting it into rectangular sheets, placing the sheets of leather into the feeding conveying assembly 22 for conveying, the feeding conveying assembly 22 conveys the leather into the drying conveying assembly 23, and then sequentially passes through the constant temperature conveying assembly 24, the cooling conveying assembly 31 and the discharging conveying assembly 32, drying the leather when passing through the drying conveying assembly 23, subjecting the dried leather to a constant temperature transition when passing through the constant temperature conveying assembly 24, air cooling the leather when passing through the cooling conveying assembly 31, and finally conveying the leather toward the softening mechanism 4 through the discharging conveying assembly 32; Step S2, conveying and softening: after the leather is dried and cooled, the leather is conveyed to the first softening conveying assembly 41 through the discharging conveying assembly 32, and the first softening conveying assembly 41 conveys the leather to the second softening conveying assembly 43. The first softening driving assembly 42 and the second softening driving assembly 44 are both vibrators. After the leather is conveyed from the first softening conveying assembly 41 to the second softening conveying assembly 43, the first softening driving assembly 42 and the second softening driving assembly 44 are vibrated by the vibrator, so that the hardened fibers of the leather after drying are softened; Step S3, transfer and lamination: after the leather is softened, the leather is transferred to the lamination mechanism 5, and the lamination mechanism 5 laminarly ... Step S4, transfer and shaping: after the roller pressing and lamination is completed, the belt-shaped material with leather is transferred and transported by the transfer mechanism 6. During the transportation process, the lamination side is cooled and shaped by blowing air; Step S5, transfer needling: when the strip material enters the needling and pressing mechanism 7 from the transfer mechanism 6, the two sides of the strip material are pressed and conveyed by the needling and pressing conveying component 71, and then the inner layer of the leather is needled by the needling and pressing mechanism 7 to pierce the fiber web into the inner layer of the leather and pierce the membrane material at the same time, so that the leather can be breathable.

[0050] In this embodiment, in the feeding and drying stage of step S1, the uniformity and standardization of the leather raw materials are ensured through pretreatment and precise cutting, laying a good foundation for subsequent processing. The integrated design of the continuous conveying component (including the drying, constant temperature, cooling and discharge conveying component 32) not only realizes the seamless connection from pretreatment to softening of the leather, but also effectively avoids the internal stress of the leather caused by the rapid temperature change through the constant temperature transition and air cooling technology, ensuring the dimensional stability and uniformity of the surface quality of the leather. This step significantly improves the drying efficiency and quality control level of the leather.

[0051] Entering the conveying and softening link of step S2, a vibrator is innovatively introduced as the driving source of the first and second softening conveying components 43. The vibration not only promotes the loosening and rearrangement of the internal fibers of the leather, but also effectively softens the fiber structure hardened due to drying, creating more favorable conditions for the subsequent pressing process. This step greatly enhances the softness and comfort of the leather, while maintaining the original toughness and durability of the leather.

[0052] In the transfer and lamination stage of step S3, the BOPE film, the plain fiber net and the inner layer of the leather are compositely connected by hot rolling technology, realizing the multi-layer structure integration of the leather. The high strength and toughness of the BOPE film, as well as the good air permeability and support of the plain fiber net, jointly improve the overall performance of the leather, such as enhancing the wear resistance, tear resistance and air permeability of the leather. The hot rolling process not only ensures the close adhesion between the layers, but also avoids damage caused by overheating of the leather through precise temperature control, maintaining the natural beauty of the leather.

[0053] In the transfer and shaping process of step S4, the shape of the composite leather is quickly fixed by the air cooling technology, thereby improving the dimensional stability and durability of the product. This step ensures that the leather is not easily deformed during subsequent processing and use, and maintains a good appearance and performance.

[0054] Finally, in the transfer needling process of step S5, the synergistic effect of the needling conveying assembly 71 and the needling mechanism 7 not only penetrates the fiber mesh deeply into the inner layer of the leather, but also penetrates the membrane material to form a microporous structure, which significantly improves the air permeability and comfort of the leather. This innovative process not only meets the high requirements of modern leather products for air permeability, but also gives the leather a more natural and comfortable feel. Through a series of finely designed steps, the present invention not only significantly improves the production efficiency and product quality of leather, but also gives the leather more superior physical properties and comfort, meeting the market's diversified demand for high-quality leather products.

[0055] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
