[0020] Please see Figures 1 to 6 This invention provides a leather processing flattening device according to one embodiment, comprising a flattening mechanism 10. The flattening mechanism 10 includes a flattening support 11, a flattening feed platform 12 mounted on the flattening support 11, a lower pressing module 13 mounted on the flattening support 11, an upper pressing module 14 mounted on the flattening support 11, and a flattening discharge module 15 mounted on the flattening support 11. The lower pressing module 13 and the upper pressing module 14 are disposed between the flattening feed platform 12 and the flattening discharge module 15. The lower pressing module 13 includes components mounted on the flattening support 11. The upper pressing module 14 includes a pressing support frame 130, a pressing slide rail 131 mounted on the pressing support frame 130, a pressing slide plate 132 slidably mounted on the pressing slide rail 131, a pressing push assembly 133 mounted on the pressing support frame 130 for pushing the pressing slide plate 132 to move, a pressing roller 134 rotatably mounted on the pressing slide plate 132, and a pressing drive motor 135 mounted on the pressing slide plate 132 for driving the pressing roller 134 to move; the direction of movement of the pressing slide plate 132 is perpendicular to the length direction of the upper pressing module 14.

[0021] The working principle of the leather processing flattening device of this utility model is as follows: The leather is first conveyed to the flattening feed table 12. The feed table provides initial support and guidance for the leather, ensuring that the leather can enter the subsequent flattening stage smoothly and accurately, avoiding the flattening effect due to positional deviation. The pressing push component 133 pushes the pressing slide plate 132, causing it to slide up and down along the pressing slide rail 131, driving the pressing roller 134 installed on the pressing slide plate 132 to move towards the pressing module 14, thereby adjusting the distance between the pressing roller 134 and the pressing module 14 (which is fixed) to adapt to the thickness of the leather to be flattened. After the distance is adjusted, the leather passes through the pressing roller 134 and the pressing module 14. The pressure formed by the two acts on the surface of the leather, flattening the wrinkles and uneven areas of the leather surface, and realizing the shaping treatment of the leather.

[0022] Compared with the prior art, the leather processing flattening device of this utility model adjusts the distance between the lower pressure roller 134 and the upper pressure module 14 by the lower pressure pushing component 133, ensuring the consistency and reliability of the flattening effect and avoiding uneven flattening or damage to the leather due to improper spacing; the pressure between the lower pressure roller 134 and the upper pressure module 14 is evenly distributed, which can effectively remove wrinkles and unevenness on the leather surface and improve the flatness and quality of the leather.

[0023] Please refer to Figure 2 and Figure 3 The pressing and pushing assembly 133 includes a pressing threaded hole 1330 disposed on the pressing support frame 130, a pressing drive screw 1331 threadedly connected to the pressing threaded hole 1330, and a rotary knob 1332 mounted on one end of the pressing drive screw 1331; the free end of the pressing drive screw 1331 is connected to the pressing slide plate 132. By rotating the rotary knob 1332, the length of the pressing drive screw 1331 can be precisely adjusted, thereby precisely controlling the up and down movement of the pressing slide plate 132. This fine-tuning capability ensures that the gap between the pressing roller 134 and the pressing module 14 can be precisely adjusted according to the thickness and material of the leather, achieving a consistent flattening effect; the design of the rotary knob 1332 makes operation simple and intuitive, requiring no complicated tools or equipment, allowing operators to easily adjust the gap and improving operational convenience.

[0024] Please refer to Figure 2 and Figure 5The pressing module 14 includes an pressing bracket 140 mounted on a pressing bracket 11, a pressing drive motor 141 mounted on the pressing bracket 140, a pressing drive wheel 142 mounted on the pressing drive motor 141, a pressing roller 143 rotatably mounted on the pressing bracket 11, a pressing driven wheel 144 mounted at one end of the pressing roller 143, and a pressing belt 145 driving the pressing drive wheel 142 and the pressing driven wheel 144. The pressing drive motor 141 drives the pressing roller 143 to rotate through the pressing drive wheel 142 and the pressing belt 145, ensuring that the pressing roller 143 can cooperate evenly and continuously with the lower pressing roller 134 to flatten the leather. This power transmission method can ensure the uniform distribution of pressure during the flattening process and improve the uniformity of the flattening effect. The automated design of the pressing module 14 reduces manual operation. The rotation of the pressing roller 143 can be controlled by the motor to achieve continuous and efficient operation, greatly improving production efficiency.

[0025] Please refer to Figure 2 and Figure 4 The flattening and discharge module 15 includes a discharge baffle 150 mounted on the flattening bracket 11 and a discharge enclosure 151 mounted on the discharge baffle 150. A discharge channel 152 is provided on the discharge enclosure 151, which is located between the upper pressing module 14 and the lower pressing module 13. The discharge baffle 150 and the discharge enclosure 151 provide a smooth output path for the flattened leather, ensuring that the leather can be smoothly and stably output from the flattening device, avoiding leather deviation or jamming due to an unclear path. The discharge channel 152, located between the upper pressing module 14 and the lower pressing module 13, ensures that the leather can quickly leave the flattening area after flattening, reducing the time the leather spends in the flattening area and thus reducing the possibility of new wrinkles or deformations during the output process.

[0026] The flattening and unloading module 15 also includes a cooling enclosure 153 disposed on the unloading baffle 150; the cooling enclosure 153 is disposed on the unloading channel 152, and a cooling air inlet channel 154 is also provided on the unloading enclosure 151; the cooling air inlet channel 154 is disposed at the top of the unloading channel 152. The design of the cooling enclosure 153 and the cooling air inlet channel 154 can guide external cold air into the unloading channel 152 to quickly cool the leather that has just undergone flattening. Rapid cooling helps to fix the shape of the leather and prevent deformation or springback caused by excessive temperature; through rapid cooling, the springback phenomenon of the leather after flattening can be effectively prevented, ensuring the flatness and shaping effect of the leather surface and improving the final quality of the leather.

[0027] Please refer to Figure 1 and Figure 6The leather processing flattening device also includes a cutting mechanism 20; the cutting mechanism 20 includes a cutting table 21, a cutting conveyor belt 22 mounted on the cutting table 21, and a cutting module 23 mounted on the cutting table 21; the cutting conveyor belt 22 is located on the discharge side of the flattening discharge module 15; the cutting module 23 is located on top of the cutting conveyor belt 22. The cutting conveyor belt 22, located on the discharge side of the flattening discharge module 15, achieves seamless connection between the flattening and cutting processes, ensuring the continuity of leather from flattening to cutting, reducing downtime in intermediate steps, and improving overall production efficiency; the cutting module 23, located on top of the cutting conveyor belt 22, can precisely control the cutting position and the movement of the cutting tools, ensuring the accuracy and consistency of each cut, and reducing waste and defective products.

[0028] The cutting module 23 includes a cutting bracket 230 mounted on the cutting table 21, a cutting Y-axis moving component 231 mounted on the cutting bracket 230, a cutting X-axis moving component 232 mounted on the cutting Y-axis moving component 231, a cutting Z-axis moving component 233 mounted on the cutting X-axis moving component 232, and a cutting component 234 mounted on the cutting Z-axis moving component 233. Through the Y-axis, X-axis, and Z-axis moving components on the cutting bracket 230, precise movement in three-dimensional space can be achieved, ensuring high-precision positioning of the cutting component 234 in the X, Y, and Z directions, improving the accuracy and consistency of cutting. The multi-axis moving component design allows the cutting component 234 to flexibly adjust its position and angle to adapt to the cutting needs of leather of different shapes and sizes, improving the versatility and flexibility of the equipment.

[0029] Two cutting supports 230 are provided, positioned on the cutting tables 21 on both sides of the conveyor belt. The two supports 230, located on opposite sides of the conveyor belt, provide more stable support, ensuring that the cutting module 23 does not shift or shake during movement and cutting, thus improving the stability and reliability of the equipment. The dual-support design better secures the cutting module 23, ensuring precise movement of the Y-axis, X-axis, and Z-axis moving components, thereby improving cutting accuracy and consistency and reducing cutting errors.

[0030] The movement direction of the cutting Y-axis moving component 231 is the same as that of the pressing slide plate 132. This consistency ensures the uniformity and synchronization of the cutting and flattening actions, improving the coordination of the entire production process. The uniformity of the movement direction reduces interference between the cutting component 234 and the pressing slide plate 132, preventing equipment malfunctions or cutting errors caused by inconsistent directions. Furthermore, because the cutting Y-axis moving component 231 and the pressing slide plate 132 move in the same direction, the cutting position can be quickly located after flattening, reducing adjustment time and improving production efficiency.

[0031] The Y-axis cutting component 231 includes a Y-axis cutting groove 2310 disposed on the cutting bracket 230, a Y-axis cutting bracket 2311 slidably disposed on the Y-axis cutting groove 2310, and a Y-axis cutting drive component 2312 mounted on the Y-axis cutting groove 2310 for driving the movement of the Y-axis cutting bracket 2311; the X-axis cutting component 232 is mounted on the Y-axis cutting bracket 2311. The combination of the Y-axis cutting groove 2310 and the Y-axis cutting bracket 2311 enables precise sliding in the Y-axis direction, ensuring high-precision movement of the cutting module 23 in the Y-axis direction; the Y-axis cutting drive component 2312 can precisely control the movement of the Y-axis cutting bracket 2311, ensuring the accuracy and stability of the movement and improving the cutting precision; the structural design of the Y-axis cutting groove 2310 and the Y-axis cutting bracket 2311 provides stable support, ensuring the smoothness of the cutting module 23 during movement and reducing shaking and offset.

[0032] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
