Description

Technical Field

[0001] This utility model relates to the field of leather product manufacturing technology, specifically to a leather stretching and flattening device for leather product manufacturing. Background Technology

[0002] Leather products are clothing, leather goods, leather shoes, and other items made primarily from leather, fur, and pelts. These products include, but are not limited to, leather jackets, leather shoes, leather bags, and leather gloves. They are typically made from natural or synthetic leather and are characterized by their durability and aesthetic appeal.

[0003] During the production of leather products, natural leather is generally uneven and varies in thickness, resulting in wrinkles or unevenness on the surface.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figures 1 to 4 As shown, this utility model discloses a leather stretching and flattening device for leather product production, including a processing table 1, on which a leather 18 is placed. A fixing plate 3 is fixedly installed on one side of the top surface of the processing table 1. A cylinder 6 is installed on the fixing plate 3, and a pressure plate 5 is fixedly connected to the telescopic end of the cylinder 6. By driving the pressure plate 5 downward through the cylinder 6, one end of the leather 18 can be fixed.

[0017] The bottom end of the fixed plate 3 is provided with a sliding groove, and a sliding groove 19 is provided on one side of the sliding groove. A connecting block 20 is slidably disposed in the sliding groove 19 and is fixedly connected to the pressure plate 5. During the process of the cylinder 6 driving the pressure plate 5 to move up and down, the pressure plate 5 moves in the sliding groove 19 through the connecting block 20, which can play a guiding role.

[0018] A fixed frame 15 is fixedly connected to one side of the processing table 1. The fixed frame 15 is L-shaped, and a linear guide rail 11 is fixedly installed at the bottom of the horizontal section of the fixed frame 15. A cylinder 13 is installed on the linear guide rail 11, and a mounting frame 14 is fixedly connected to the telescopic end of the cylinder 13. A pressure roller 10 is detachably installed on the mounting frame 14. The position of the pressure roller 10 can be adjusted by the linear guide rail 11, so that the pressure roller 10 moves along the surface of the leather 18 to roll it. The height of the pressure roller 10 can be adjusted by the cylinder 13, which is convenient for rolling leather 18 of different thicknesses and also convenient for picking up and putting down the leather 18.

[0019] A slider 12 is slidably mounted on the linear guide rail 11, and a cylinder 13 is fixedly mounted on the bottom end of the slider 12. The slider 12 drives the cylinder 13 to move, thereby adjusting the position of the cylinder 13 and consequently the position of the pressure roller 10.

[0020] The fixing frame 15 is U-shaped, and the two ends of the pressure roller 10 are rotatably connected to the connectors. The fixing frame 15 is equipped with fastening bolts, and one end of the fastening bolts is connected to the connectors. When it is necessary to disassemble the pressure roller 10, the fastening bolts can be unscrewed first, and then the pressure roller 10 can be separated from the fixing frame 15.

[0021] On the other side of the processing table 1, a threaded rod 7 is rotatably mounted. A slide plate 8 is threadedly connected to the threaded rod 7. A cylinder 3 16 is mounted on the slide plate 8, and a pressure plate 2 17 is fixedly connected to the telescopic end of the cylinder 3 16. The position of the slide plate 8 can be adjusted by rotating the threaded rod 7, thereby adjusting the position of the pressure plate 2 17, so as to press the leather 18 according to the stretching requirements and the length of the leather 18.

[0022] After the two ends of the leather 18 are fixed by the pressure plate 15 and the pressure plate 2 17, the surface of the leather 18 is rolled by the pressure roller 10. After rolling, the leather 18 becomes longer. At this time, the cylinder 3 16 drives the pressure plate 2 17 upward and straightens the leather 18. Then, the pressure plate 2 17 presses the leather 18 so that it is in a stretched state. During this process, the position of the slide plate 8 can be adjusted to adapt to the position of the pressure plate 2 17.

[0023] A mounting groove 4 is provided on the side of the processing table 1. One end of the threaded rod 7 is rotatably mounted in the mounting groove 4, and the other end of the threaded rod 7 rotatably passes through and extends to the outside of the processing table 1. A motor 9 is mounted on one end of the processing table 1, and the output end of the motor 9 is fixedly connected to the extended end of the threaded rod 7. The motor 9 is a forward and reverse motor, which can drive the threaded rod 7 to rotate when it is working, thereby causing the slide plate 8 to move along the threaded rod 7, thus adjusting the position of the slide plate 8.

[0024] A controller 2 is installed on one side of the processing table 1. Cylinder 1 (6), Cylinder 2 (13), Cylinder 3 (16), Linear guide rail 11, and Motor 9 are all electrically connected to the controller 2. The controller 2 is an SC200 model. By controlling the start and stop of Cylinder 1 (6), Cylinder 2 (13), Cylinder 3 (16), Linear guide rail 11, and Motor 9, the controller can press, roll, and stretch the leather 18 to achieve a flattening effect.

[0025] During operation, before stretching and flattening the leather 18, the ends of the leather 18 are first fixed by pressure plate 15 and pressure plate 27. Then, the leather 18 is rolled by pressure roller 10 to make its surface flat. During the rolling process, the pressing position of pressure plate 27 can be adjusted according to the length of the leather 18 after rolling. After rolling, the leather 18 is stretched to ensure the flatness effect. This utility model can improve production efficiency while ensuring production quality.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
