[0002] In the modern leather goods industry, full-grain cowhide is favored by consumers as an ideal material for sofa leather production due to its superior qualities, such as natural texture, excellent durability, and good breathability. However, its processing faces many challenges and places extremely high demands on processing equipment. When sofa leather is not stretched taut, it is prone to wrinkles, which affects the later processing of the sofa leather.

[0003] Chinese utility model patent application number 202420250533.4 provides a sofa leather processing, leveling, and winding machine. When winding sofa leather, the operator winds the sofa leather around the winding rod, moves the limiting plate to move the sleeve along the rod wall, adjusts the distance between the limiting plate and the disc, and rotates the locking bolt to press the winding rod, thus fixing the limiting plate. The controller controls the motor to drive the disc to rotate, thereby winding the sofa leather.

[0004] During the use of the aforementioned equipment, it was found that when rolling up sofa leather, operators need to adjust the position of the limiting plate and then fix it with bolts. Each time the roll-up rod is replaced, the operator needs to reinstall the rod, move the limiting plate, adjust the spacing, and tighten the locking bolts, among other operations. This undoubtedly increases the time cost of replacing the roll-up rod. Especially in production scenarios requiring frequent roll-up operations, a significant amount of time is wasted on these repetitive adjustments, resulting in low overall work efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see Figures 1-4This utility model provides a processing equipment for full-grain cowhide natural texture sofa leather, including an operating table 1. An installation component 2 is mounted on one end of the operating table 1. The installation component 2 includes an installation frame 22. A first motor 21 is mounted on one side of the installation frame 22. The output end of the first motor 21 is connected to a first bidirectional threaded rod 24. First sliding rods 23 are arranged parallel to each other on both sides of the first bidirectional threaded rod 24. A first movable frame 25 is screwed onto both ends of the first bidirectional threaded rod 24, and the first movable frame 25 is slidably mounted. On the first slide bar 23, a clamping frame 26 is fixedly connected to the bottom of the first movable frame 25. A turntable 27 is rotatably mounted on the clamping frame 26. Positioning rods 271 are arranged in a ring array on the turntable 27. A take-up roller 3 is clamped and mounted between the turntables 27 of the mounting assembly 2. A second motor 28 is mounted on the clamping frame 26 at one end of the first bidirectional threaded rod 24. The output end of the second motor 28 is connected to the turntable 27 on the clamping frame 26. An adjustment assembly 4 is provided on the operating table 1. The adjustment assembly 4 is connected to the leveling component 5.

[0025] The first bidirectional threaded rod 24 is rotatably mounted on the mounting bracket 22, and the first sliding rod 23 is fixedly mounted on the mounting bracket 22;

[0026] The adjustment assembly 4 includes an adjustment frame 41, which is arranged on both sides of the operating table 1. A third motor 42 is installed on the adjustment frame 41. The output end of the third motor 42 is connected to a second bidirectional threaded rod 44. A second slide rod 43 is arranged parallel to both sides of the second bidirectional threaded rod 44. A second movable frame 45 is screwed onto both ends of the second bidirectional threaded rod 44. The second movable frame 45 is slidably mounted on the second slide rod 43. A connecting rod 46 is rotatably mounted on the bottom of the second movable frame 45. The connecting rod 46 is connected to the leveling component 5.

[0027] The second bidirectional threaded rod 44 is rotatably mounted on the adjusting frame 41, and the second slide rod 43 is fixedly mounted on the adjusting frame 41. The second movable frames 45 and connecting rods 46 at both ends of the second bidirectional threaded rod 44 are symmetrical to each other.

[0028] Specifically, in the installation assembly 2, after the first motor 21 starts, its output end drives the first bidirectional threaded rod 24 to rotate. Since the threads at both ends of the first bidirectional threaded rod 24 are in opposite directions, and the first movable frames 25 are respectively screwed to both ends of the first bidirectional threaded rod 24, and the first movable frames 25 are slidably mounted on the first slide rod 23, when the first bidirectional threaded rod 24 rotates, the two first movable frames 25 will move in opposite or opposite directions along the first slide rod 23. By controlling the forward and reverse rotation of the first motor 21, the two first movable frames 25 can be brought closer to each other, thereby driving the bottom clamping frame 26 to move closer. At this time, the take-up roller 3 is placed between the two turntables 27, and the positioning rods 271 arranged in a ring array on the turntables 27 are used to position the take-up roller 3, completing the installation of the take-up roller 3.

[0029] After the take-up roller 3 is installed, one end of the leather material is wound around the take-up roller 3. The second motor 28 is started, and its output end drives the turntable 27 connected to it to rotate. Since the take-up roller 3 is positioned between the two turntables 27, the take-up roller 3 will rotate together with the turntables 27, thereby realizing the leather take-up operation.

[0030] In the adjusting assembly 4, after the third motor 42 is started, its output end drives the second bidirectional threaded rod 44 to rotate. Similarly, the threads at both ends of the second bidirectional threaded rod 44 are in opposite directions. The second movable frame 45 is helically connected to both ends of the second bidirectional threaded rod 44 and is slidably mounted on the second slide rod 43. Therefore, when the second bidirectional threaded rod 44 rotates, the two second movable frames 45 will move in opposite or opposing linear directions along the second slide rod 43.

[0031] Because a connecting rod 46 is rotatably mounted on the bottom of the second movable frame 45, and the connecting rod 46 is connected to the leveling component 5, and the second movable frames 45 and the connecting rod 46 at both ends of the second bidirectional threaded rod 44 are symmetrical to each other, when the two second movable frames 45 move towards each other, the leveling component 5 will descend through the transmission action of the connecting rod 46; when the two second movable frames 45 move away from each other, the leveling component 5 will rise. By controlling the forward and reverse rotation of the third motor 42, the height of the leveling component 5 can be precisely adjusted to make it contact the leather surface and apply appropriate pressure.

[0032] As the take-up roller 3 rotates to take in the leather, the leveling component 5 is adjusted to a suitable height by the adjusting assembly 4, ensuring close contact with the leather surface. At this time, the leveling component 5 applies pressure to the leather, smoothing out wrinkles on the leather surface. As the take-up roller 3 continues to rotate, the leather is continuously released from the take-up roller 3 and passes under the leveling component 5. During this process, the leveling component 5 rolls on the leather surface, further eliminating wrinkles through continuously applied pressure and friction, making the leather surface smoother.

[0033] The installation component 2 simplifies and speeds up the installation and removal of the take-up roller 3. Operators can select the appropriate take-up roller 3 and control the forward and reverse rotation of the first motor 21 to complete the replacement in a short time, significantly improving equipment efficiency. When producing sofa leather of different specifications requires changing the take-up roller 3, the operation can be completed quickly, reducing time costs. Furthermore, due to the bidirectional threaded structure of the first bidirectional threaded rod 24, the distance between the two first moving frames 25 can be flexibly adjusted according to the actual size of the take-up roller 3. This means that the installation component 2 can accommodate take-up rollers 3 of various diameters, enhancing the equipment's versatility and applicability.

[0034] Furthermore, to avoid situations where some wrinkles cannot be eliminated or new wrinkles are created, please refer to [link / reference needed]. Figures 1-4 The leveling component 5 includes a leveling frame 51. A connecting arm 52 is located at the top of the leveling frame 51 and is rotatably connected to a connecting rod 46. Connecting frames 53 are fixedly installed on both sides of the leveling frame 51. A guide rod 531 is fixedly installed inside the connecting frame 53, and a slider 533 is slidably mounted on the guide rod 531. The slider 533 is connected to the connecting frame 53 via a spring 532. A pressure roller 54 is rotatably mounted between the sliders 533 on both sides of the leveling frame 51.

[0035] Specifically, during the processing of leather, its thickness is not completely uniform, and the surface may have certain undulations. When the leather passes through the pressure roller 54, if the pressure roller 54 is fixed, the pressure in some areas will be insufficient due to differences in leather thickness or surface, thus preventing the wrinkles from being eliminated, or the pressure will be too high, creating new wrinkles. In this device, the slider 533 can slide on the guide rod 531 and is connected to the connecting frame 53 via the spring 532. When encountering a thicker part of the leather or a raised part of the surface, the pressure roller 54 is subjected to an upward force, and the slider 533 will slide upward along the guide rod 531 and compress the spring 532, so that the pressure roller 54 can automatically adapt to the changes in leather thickness and surface undulations, ensuring that uniform pressure is applied to the entire leather surface, thereby preventing some wrinkles from being unable to be eliminated due to uneven pressure.

[0036] Conversely, when encountering thinner or more concave areas of leather, the spring 532 will restore its elastic deformation, pushing the slider 533 downwards, ensuring that the pressure roller 54 is always in close contact with the leather surface, thus ensuring uniform pressure and preventing new wrinkles from forming due to insufficient pressure.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.

No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
