The clamping structure 2 is fixedly installed outside the installation frame one 7. A motor one 8 is fixedly arranged on the rotating mounting seat 6. The output end of the motor one 8 is fixedly connected to the outside of one end of the installation frame one 7. The device main body 1 is the foundation and support structure of the entire device, accommodating and fixing all other components inside. The clamping structure 2 is used to clamp and fix the waterproof leather to be processed, ensuring that the leather will not move or fall off during the stretching and flattening process. The electrically heated flattening roller 4 heats the surface of the roller to a certain temperature through electricity, and uses the thermal effect to soften and flatten the leather. The electric heating element 5 arranged inside the flattening table 3 is used to heat the leather, making the leather easier to stretch and improving the flattening effect of the leather. Through the installation of the rotating mounting seat 6, when one side of the leather is flattened by the electrically heated flattening roller 4, with the start of the motor one 8 on the rotating mounting seat 6, the motor one 8 drives the installation frame one 7 on the rotating mounting seat 6 to rotate, thereby driving the clamping structure 2 and the leather fixed on it to rotate, ensuring that the bottom surface of the leather that was originally difficult to reach can be fully and evenly processed. This not only significantly improves the effect and practicability of the stretching and flattening device, but also brings higher production efficiency and lower operating costs to users.

[0022] Please refer to Figure 1 and Figure 2 , Inside the device main body 1, two groups of lead screws one 9 are rotatably arranged. A lead screw nut one 10 is engaged on the lead screw one 9. The outside of the lead screw nut one 10 is fixedly connected to the bottom of the rotating mounting seat 6 through a connecting piece. A gear one 11 is fixedly arranged on the lead screw one 9. An electric motor two 12 is fixedly arranged inside the device main body 1.

With the start of the electric motor two 12, its output end will drive the gear two 13 to rotate, and then drive the gear one 11 and the lead screw one 9 to rotate through the meshing relationship. When the lead screw one 9 rotates, the lead screw nut one 10 arranged on it will move along the axial direction of the lead screw one 9. When the lead screw nut one 10 moves on the lead screw, it will drive the rotating mounting seat 6 to move together, enabling the position of the clamping structure 2 on the rotating mounting seat 6 to be adjusted, making it applicable to leathers of various sizes and facilitating the control of the stretching distance of the leather.

[0023] Please refer to Figure 1 and Figure 3, an electric heating element 5 for heating the leather on the leveling table 3 is arranged inside the leveling table 3. A plurality of support frames 23 are arranged inside the device body 1. Two lead screws 24 are rotatably arranged inside the support frame 23. A lead screw nut 25 is meshed with the outside of the lead screw 24. A support column 26 is fixedly arranged on the outside of the lead screw nut 25. The top end of the support column 26 is fixedly connected with the bottom of the leveling table 3. A first gear 27 is fixedly arranged on the lead screw 24. A rotating rod 28 is rotatably arranged inside the support frame 23. Second gears 29 are fixedly arranged at both ends of the rotating rod 28. The second gears 29 are meshed with the first gear 27. A third gear 30 is fixedly arranged on the rotating rod 28. A motor three 31 is fixedly arranged on the support frame 23. A fourth gear 32 is fixedly arranged at the output end of the motor three 31. The fourth gear 32 is meshed with the third gear 30. The electric heating element 5 arranged inside the leveling table 3 is used for heating the leather, so that the leather can be stretched more easily and the leveling effect of the leather can be improved. When the motor three 31 is started, the rotation of the rotating rod 28 can be driven by the meshing of the fourth gear 32 at its output end with the third gear 30. The rotation of the rotating rod 28 will drive the rotation of the two lead screws 24 rotatably installed inside the support frame 23 through the meshing of the second gears 29 at both ends with the first gear 27. The rotation of the lead screw 24 can drive the lead screw nut 25 engaged with it to perform a linear motion. When the lead screw nut 25 moves on the lead screw 24, it will drive the support column 26 and the leveling table 3 to lift together, realizing the precise lifting control of the leveling table 3, so that the leveling table 3 can accurately contact the bottom surface of the leather during the clamping and fixing process.

[0024] Please refer to Figure 1 and Figure 4, an installation frame two 14 is arranged inside the device main body 1. A plurality of guide rods 15 are fixedly arranged on the installation frame two 14. A guide block 16 is movably arranged on the guide rod 15. An installation piece 17 is fixedly arranged at the bottom of the guide block 16. And the electric heating flattening roller 4 is rotatably installed on the installation piece 17. A lead screw three 18 is rotatably arranged on the installation frame two 14. A lead screw nut three 19 is engaged on the lead screw three 18. And the bottom of the lead screw nut three 19 is fixedly connected with the top of the installation piece 17 through a connecting block. An electric motor four 20 is fixedly arranged outside the installation frame two 14. The output end of the electric motor four 20 is fixedly connected with the outer part of one end of the lead screw three 18. A plurality of electric telescopic columns 21 are fixedly installed on the inner top of the device main body 1. The output end of the electric telescopic column 21 is fixedly installed with a connecting frame 22. And the outside of the connecting frame 22 is fixedly connected with the outside of the installation frame two 14. The electric heating flattening roller 4 is rotatably installed inside the device main body 1 through the two guide rods 15 on the installation frame two 14 and the installation piece 17 at the bottom of the guide block 16 with limited movement. With the start of the electric motor four 20, its output end drives the lead screw three 18 to rotate. The rotation of the lead screw three 18 will drive the lead screw nut three 19 to move along the lead screw three 18. The movement of the lead screw nut three 19 will drive the electric heating flattening roller 4 to move through the installation piece 17. With the movement of the electric heating flattening roller 4, when the electric heating flattening roller 4 contacts the leather, it can cooperate with the flattening table 3 to flatten the leather by rolling. With the start of the electric telescopic column 21, the connecting frame 22 fixedly installed at its output end can drive the installation frame two 14 and the electric heating flattening roller 4 above it to move up and down, so that the electric heating flattening roller 4 can accurately contact the top surface of the leather during the clamping and fixing process. When the rotating mounting seat 6 needs to drive the clamping structure 2 and the leather fixed on it to rotate, the electric telescopic column 21 will drive the installation frame two 14 and the electric heating flattening roller 4 above it to move up, and the support frame 23 will drive the flattening table 3 to move down, so that there is enough space inside the device main body 1 for the leather to rotate.

[0025] Working principle: The device main body 1 serves as the foundation and support structure of the entire device, accommodating and fixing all other components inside. The clamping structure 2 is used to clamp and fix the waterproof leather to be processed, ensuring that the leather does not move or fall off during the stretching and flattening process. The electrically heated flattening roller 4 reaches a certain temperature on the roller surface through electric heating, and uses the thermal effect to soften and flatten the leather. The electric heating element 5 installed inside the flattening table 3 is used to heat the leather, making the leather easier to stretch and improving the flattening effect of the leather. Through the installation of the rotating mounting base 6, when one side of the leather is flattened by the electrically heated flattening roller 4, with the start of the motor one 8 on the rotating mounting base 6, the mounting frame one 7 on the rotating mounting base 6 is driven to rotate by the motor one 8, thereby driving the clamping structure 2 and the leather fixed on it to rotate, ensuring that the bottom surface of the leather that was originally difficult to reach can be fully and evenly processed. This not only significantly improves the effect and practicality of the stretching and flattening device, but also brings higher production efficiency and lower operating costs to users. With the start of the motor two 12, its output end will drive the gear two 13 to rotate, and then drive the gear one 11 and the lead screw one 9 to rotate through the meshing relationship. The rotation of the lead screw one 9 causes the lead screw nut one 10 arranged on it to move along the axial direction of the lead screw one 9. When the lead screw nut one 10 moves on the lead screw, it will drive the rotating mounting base 6 to move together, enabling the position of the clamping structure 2 on the rotating mounting base 6 to be adjusted, making it applicable to leathers of various sizes and facilitating the control of the stretching distance of the leather. The electric heating element 5 installed inside the flattening table 3 is used to heat the leather, making the leather easier to stretch and improving the flattening effect of the leather. When the motor three 31 starts, the rotation of the fourth gear 32 at its output end meshing with the third gear 30 can drive the rotating rod 28 to rotate. The rotation of the rotating rod 28 will drive the two lead screws two 24 rotatably installed inside the support frame 23 through the meshing of the second gears 29 at both ends with the first gear 27. The rotation of the lead screws two 24 can drive the lead screw nuts two 25 engaged with them to perform linear motion. When the lead screw nuts two 25 move on the lead screws two 24, they will drive the support column 26 and the flattening table 3 to lift together, achieving precise lifting control of the flattening table 3, enabling the flattening table 3 to accurately contact the bottom surface of the leather during the clamping and fixing process. The electrically heated flattening roller 4 is rotatably installed inside the device main body 1 through the installation parts 17 at the bottom of the two guide rods 15 and guide blocks 16 on the mounting frame two 14 for limit movement. With the start of the motor four 20, its output end drives the lead screw three 18 to rotate. The rotation of the lead screw three 18 will drive the lead screw nut three 19 to move along the lead screw three 18. The movement of the lead screw nut three 19 will drive the electrically heated flattening roller 4 to move through the installation parts 17. As the electrically heated flattening roller 4 moves, when it comes into contact with the leather, it can cooperate with the flattening table 3 to flatten the leather by rolling. With the start of the electric telescopic column 21, the connecting frame 22 fixedly installed at its output end can drive the mounting frame two 14 and the electrically heated flattening roller 4 above it to lift and move.The electric heating flattening roller 4 can be accurately brought into contact with the top surface of the leather during the clamping and fixing process. When the rotary mounting seat 6 needs to drive the clamping structure 2 and the leather fixed thereon to rotate, the electric telescopic column 21 will drive the mounting frame II 14 and the electric heating flattening roller 4 above it to move upward, and the support frame 23 will drive the flattening table 3 to move downward, so that there is enough space in the device main body 1 for the leather to rotate.
