The rear top of the leather smoothing table 1 is connected to the bottom of the rear frame 2. The middle of the top of the rear frame 2 is connected to the top of the clamping cylinder 3. The output end of the clamping cylinder 3 is connected to the middle of the top of the clamping plate 4. A [unclear - possibly a device name] is provided inside the left and right sides of the leather smoothing table 1. The bottom left and right sides of the sliding groove 5 and the movable frame 6 are slidably connected to the inner sides of the sliding groove 5 on both sides, respectively. The front end of the leather flattening table 1 is connected to the rear end of the transmission box 9. The top middle of the transmission box 9 is connected to the bottom end of the drive motor 10. The driving bevel gear 11, bevel gear connecting rod 12, and driven bevel gear 13 are all movably arranged inside the transmission box 9. The output end of the drive motor 10 is connected to the top middle of the driving bevel gear 11. The outer side of the driving bevel gear 11 is movably meshed with the inner side of the two sets of bevel gear connecting rods 12. The outer sides of the two sets of bevel gear connecting rods 12 are respectively movably meshed with a set of driven bevel gears 13. The two sets of driven bevel gears 13 are connected at their rear ends to the front ends of a set of longitudinal sliding screws 23. The longitudinal sliding screws 23 are rotatably connected to the inner side of the slide groove 5. The lower inner sides of the left and right sides of the movable frame 6 are respectively connected to the outer sides of a set of longitudinal sliding sleeves 24. The inner wall of the longitudinal sliding sleeves 24 is screwed to the outer wall of the longitudinal sliding screws 23. The interior of the movable frame 6 is connected to the top of the connecting frame 7 via a clamping mechanism. An electric iron 8 is installed at the bottom of the connecting frame 7. The leather to be treated is placed on the top of the leather flattening table 1, with its rear side positioned at the bottom side of the clamping piece 4 inside the rear frame 2. The rear frame 2 is connected to... The clamping cylinder 3 operates to clamp the leather by clamping the clamping plate 4. Then, the pressing mechanism is operated to make the electric iron 8 contact the surface of the leather. Then, the drive motor 10 runs, causing the drive bevel gear 11 to rotate. The drive bevel gear 11 meshes with two sets of bevel gear connecting rods 12, and then meshes with the corresponding driven bevel gear 13 through the bevel gear connecting rods 12, driving the two sets of longitudinal moving screws 23 to rotate synchronously. The longitudinal moving screws 23 are screwed into the longitudinal moving screw sleeves 24, and the two sets of longitudinal moving screw sleeves 24 drive the movable frame 6 to move longitudinally, so that the electric iron 8 can iron the surface of the leather flat.

[0025] It also includes a cover 14. The front of the transmission box 9 is open, and the front of the transmission box 9 and the rear of the cover 14 can be detached and installed. After the cover 14 is installed on the front of the transmission box 9, the internal structure of the transmission box 9 can be protected and the reliability can be improved.

[0026] The pressing mechanism includes a sliding sleeve 15, a sliding rod 16, a pull tab 17, and a spring 18. The inner side of the top center of the movable frame 6 is connected to the outer side of the sliding sleeve 15. The inner wall of the sliding sleeve 15 is vertically slidably connected to the outer wall of the sliding rod 16. The top of the sliding rod 16 is connected to the middle of the bottom end of the pull tab 17. The bottom end of the sliding rod 16 is connected to the middle of the top of the connecting frame 7. The outer side of the sliding rod 16 at the top of the connecting frame 7 is connected to the outer side of the sliding sleeve 15 at the top of the inner part of the movable frame 6 by a spring 18. Pulling the pull tab 17 upward can overcome the elastic force of the spring 18 and move the connecting frame 7 upward, creating a space for the leather to be inserted. When the pull tab 17 is released, the sliding rod 16 slides down inside the sliding sleeve 15 under the elastic action of the spring 18, causing the connecting frame 7 to move downward and be tightly contacted by the electric iron 8 on the upper side of the leather.

[0027] It also includes a temperature sensor 19, with one side of the top of the connecting bracket 7 connected to the bottom of the temperature sensor 19, and the input end of the temperature sensor 19 connected to the output end of the electric iron 8; the temperature sensor 19 can sense the temperature of the electric iron 8 and output a signal for the user to check and operate.

[0028] It also includes a lamp holder 20 and a light bulb 21. The front side of the top of the rear frame 2 is connected to the bottom of the lamp holder 20, and the front side of the top of the inside of the lamp holder 20 is connected to the top of the light bulb 21. The light bulb 21 is connected and supported by the lamp holder 20, and the light bulb 21 provides illumination, thereby optimizing the lighting environment and improving convenience.

[0029] It also includes an anti-slip mat 22, and the bottom of the rear frame 2 at the top of the leather flattening platform 1 is connected to the bottom of the anti-slip mat 22; the anti-slip mat 22 allows the bottom of the leather to come into contact, increasing the static friction when the clamping plate 4 is clamped, and reducing the risk of movement.

[0030] In summary, when using a leather smoothing device, the leather to be processed is placed on top of the leather smoothing table 1, with its rear side positioned on the bottom side of the clamping plate 4 inside the rear frame 2. Under the connection of the rear frame 2, the clamping cylinder 3 operates, acting on the clamping plate 4 to clamp the leather. The anti-slip pad 22 allows for contact between the bottom surface of the leather, increasing the static friction of the clamping plate 4 during clamping and reducing potential movement hazards. Pulling the pull tab 17 upwards overcomes the elasticity of the spring 18, causing the connecting frame 7 to move upwards, creating space for the leather to be placed. When the pull tab 17 is released, under the elastic action of the spring 18, the sliding rod 16 slides down inside the sliding sleeve 15, causing the connecting frame 7 to move downwards, allowing the electric iron 8 to make close contact with the upper side of the leather. Then, the drive motor 10 operates... The active bevel gear 11 rotates the rod, which meshes with two sets of bevel gear connecting rods 12 and then with the corresponding driven bevel gear 13, driving two sets of longitudinal sliding screws 23 to rotate synchronously. The longitudinal sliding screws 23 are screwed into the longitudinal sliding sleeves 24, which drive the movable frame 6 to move longitudinally, allowing the electric iron 8 to iron the leather surface. At the same time, the temperature sensor 19 can sense the temperature of the electric iron 8 and output a signal for the user to check and operate. In addition, the lamp holder 20 connects and supports the lighting bulb 21, which provides illumination and optimizes the lighting environment. After the cover 14 is installed on the front side of the transmission box 9, the internal structure of the transmission box 9 can be protected.

[0031] The clamping cylinder 3, the electric iron 8, and the temperature sensor 19 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further on them here.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
