DETAILED DESCRIPTION

[0023] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0024] Please refer to Figures 1 to 4 As shown, a leather folding machine of the utility model comprises a workbench 7, a rotating frame 1, a handle 2 and a folding mechanism, one side of the workbench 7 is rotatably connected to the rotating frame 1, the other side of the rotating frame 1 close to the workbench 7 is provided with the folding mechanism, and the handle 2 is connected to the rotating frame 1;

[0025] The folding mechanism includes a folding knife 5, a sliding assembly and a rebound assembly 6. The folding knife 5 is slidably connected to the other side of the rotating frame 1 close to the workbench 7 through the sliding assembly. The rebound assembly 6 is arranged on both sides of the folding knife 5. One side of the rebound assembly 6 is connected to the folding knife 5, and the other side of the rebound assembly 6 is connected to the rotating frame 1.

[0026] The rebound component 6 includes a pressure piece 601 and an elastic reset piece 602. A receiving groove 603 matched with the elastic reset piece 602 is obliquely provided on one side of the rotating frame 1 close to the folding knife 5. The elastic reset piece 602 is arranged inside the receiving groove 603. One end of the pressure piece 601 is pressed on the elastic reset piece 602. A through hole matched with the pressure piece 601 is arranged on the folding knife 5. The pressure piece 601 is penetrated inside the through hole. The other end of the pressure piece 601 is pressed on the side of the through hole away from the elastic reset piece 602.

[0027] The working principle of the utility model is as follows: during actual production and use, when the leather needs to be folded, the position where the leather needs to be folded can be placed under the folding knife 5, and then the operator drives the rotating frame 1 to rotate through the handle 2, so that the rotating frame 1 drives the folding knife 5 to fold the leather. Since the operator applies downward pressure to the folding knife 5, when the folding knife 5 reaches the workbench 7, the workbench 7 squeezes the folding knife 5. At this time, the folding knife 5 slides upward through the sliding assembly. While sliding, the folding knife 5 also drives the pressure piece 601 to squeeze the elastic reset piece 602. When the operator releases the downward pressure on the rotating frame 1, the elastic reset piece 602 resets in the accommodating groove 603, so that the rotating frame 1 automatically tilts to the side of the rotating frame 1 away from the folding knife 5.

[0028] Furthermore, the sliding assembly includes a limit head 4 and a threaded column, the folding knife 5 is provided with a movable groove adapted to the threaded column, the threaded column can be movably connected inside the movable groove, the rotating frame 1 is provided with an internal thread adapted to the threaded column, one end of the threaded column is passed through the internal thread, the threaded column is meshed with the internal thread, and the other end of the threaded column is provided with the limit head 4, and the limit head 4 is pressed on the side of the movable groove away from the internal thread.

[0029] From the above description, it can be seen that when the operator drives the rotating frame 1 to press down through the handle 2, the rotating frame 1 drives the folding knife 5 to fold the leather. When the folding knife 5 presses down on the leather, the folding knife 5 moves upward under the repulsive force of the leather, and at the same time, the folding knife 5 slides in the movable groove through the threaded column. Then, while the folding knife 5 slides upward, the folding knife 5 drives the pressure piece 601 to squeeze the elastic reset piece 602. When the operator releases the downward pressure on the rotating frame 1, the elastic reset piece 602 resets in the accommodating groove 603, so that the rotating frame 1 automatically tilts to the side of the rotating frame 1 away from the folding knife 5, thereby achieving the effect of automatically lifting the folding knife 5. The clamping force of the limit head 4 on the folding knife 5 can be adjusted by the threaded column, so that the folding knife 5 can slide better on the rotating frame 1.

[0030] Furthermore, it also includes an angle adjustment component 3, which is provided on the side of the rotating frame 1 away from the folding knife 5, the lower part of the angle adjustment component 3 is connected to the workbench 7, and the rotating frame 1 is movably connected to the upper part of the angle adjustment component 3.

[0031] From the above description, it can be known that the position of the rotating frame 1 after rebounding can be limited according to the angle adjustment component 3, so that the operator can adjust to a comfortable processing angle.

[0032] Furthermore, the angle adjustment assembly 3 includes a fixed block 307, a longitudinal slide rail 303, an angle adjustment block 302, a slide rod 304, a support block 301 and a disassembly piece 305. The longitudinal slide rail 303 is detachably connected to the workbench 7 through the fixed block 307. The longitudinal slide rail 303 is provided with a first slide groove 306. The slide rod 304 is inserted into the first slide groove 306 and is slidably connected to the first slide groove 306. An angle adjustment block 302 is provided on both sides of the longitudinal slide rail 303. A second slide groove is provided in the middle of the angle adjustment block 302. The angle adjustment block 302 is sleeved on the outside of the slide rod 304 through the second slide groove. The angle adjustment block 302 is detachably connected to the longitudinal slide rail 303 through the disassembly piece 305. The support block 301 is provided on the side of the angle adjustment block 302 close to the rotating frame 1.

[0033] From the above description, it can be seen that when it is necessary to adjust the rebound lifting angle of the rotating frame 1, the angle adjustment block 302 can be rotated to rotate on the slide bar 304, so that the angle adjustment block 302 drives the support block 301 to adjust to a suitable support angle for the rotating frame 1, and then the position between the angle adjustment block 302 and the longitudinal slide rail 303 is fixed by the disassembly part 305, so that the lifting angle of the rotating frame 1 is controlled and limited, and the slide bar 304 can drive the angle adjustment block 302 to move in the first slide groove 306, so that the angle adjustment block 302 can be adjusted to a suitable height.

[0034] Furthermore, a protection pad 308 is included. The protection pad 308 is disposed on a side of the support block 301 close to the rotating frame 1 .

[0035] It can be seen from the above description that it is beneficial to better support the rotating frame 1 through the protection pad 308 and reduce the impact force of the protection pad 308 on the rotating frame 1.
