[0018] This disclosure provides a leather cutting device for bags, including a cutting platform, a first support plate, a hollow shaft, a vibrating knife, a support rod, a motor mounting plate, a drive motor, a transmission component, and a driving component. The cutting platform supports and holds pieces of leather to be cut. The first support plate, along the height of the cutting platform, is located above the cutting platform and supports related components of the device. The hollow shaft, along the height of the cutting platform, is rotatably mounted on the first support plate and can rotate relative to the first support plate. The vibrating knife is detachably mounted inside the hollow shaft and rotates under the drive of the hollow shaft. The blade of the vibrating knife faces the cutting platform to cut the leather placed on the platform. The support rod, along the height of the cutting platform, is mounted on the first support plate and located to the side of the hollow shaft, supporting the motor mounting plate.

[0036] Combination Figures 1 to 4 As shown in the figure, this disclosure provides a leather cutting device for bags, including a cutting platform 1, a first support plate 2, a hollow shaft 3, a vibrating knife 4, a support rod 5, a motor mounting plate 6, a drive motor 7, transmission components, and a driving component. The cutting platform 1 is used to support and place pieces of leather to be cut. The first support plate 2 is located above the cutting platform 1 along its height direction and is used to support related components of the device. The hollow shaft 3 is rotatably mounted on the first support plate 2 along the height direction of the cutting platform 1 and can rotate relative to the first support plate 2. The vibrating knife 4 is detachably installed inside the hollow shaft 3 and rotates under the drive of the hollow shaft 3. The blade of the vibrating knife 4 faces the cutting platform 1 to cut the leather placed on the cutting platform 1. The support rod 5 is mounted on the first support plate 2 along the height direction of the cutting platform 1 and is located to the side of the hollow shaft 3, used to support the motor mounting plate 6. The motor mounting plate 6 is mounted on the top of the support rod 5 and is used to support the drive motor 7. A drive motor 7 is mounted on a motor mounting plate 6. The axis of the rotating end of the drive motor 7 is parallel to the axis of the hollow shaft 3, providing driving force to achieve the rotational motion function. A transmission component is installed between the rotating end of the drive motor 7 and the outer wall of the hollow shaft 3 to transmit driving force, causing the hollow shaft 3 to rotate under the drive of the drive motor 7. A drive component is installed between the cutting platform 1 and the first support plate 2 to provide driving force, driving the first support plate 2 to move in three-dimensional space. Under the drive of the drive component, the vibrating blade 4 can abut against the top surface of the cutting platform 1 and move along the top surface of the cutting platform 1.

[0037] This disclosure provides a leather cutting device for bags and luggage. By controlling the drive component, a first support plate 2 can move within a three-dimensional space. This, in turn, moves a hollow shaft 3 within the three-dimensional space, ultimately causing a vibrating blade 4 to move freely within the space. This allows the vibrating blade 4 to abut against the top surface of the cutting platform 1 and move along that surface. By controlling the drive motor 7, the hollow shaft 3 can rotate via a transmission component, thereby rotating the vibrating blade 4 and changing the cutting direction of its blade head. This allows the blade head of the vibrating blade 4 to automatically change its cutting direction with the direction of movement, thus cutting leather of different shapes and improving its applicability.

[0039] In this embodiment, the transmission component includes a driving gear 8, a driven gear 9, and a synchronous toothed belt 10 for transmitting driving force. During use, controlling the drive motor 7 to operate drives the driving gear 8 to rotate. The synchronous toothed belt 10 then drives the driven gear 9 to rotate, which in turn drives the hollow shaft 3 to rotate, ultimately causing the vibrating blade 4 to rotate. Furthermore, the design of the driving gear 8 having a smaller diameter than the driven gear 9 reduces the rotational speed.

[0040] Optionally, combined Figures 1 to 4 As shown, the driving component includes a second support plate 11 and a first linear slide 12.

During use, controlling the operation of the second linear slide 14 can drive the second support plate 11 to move along the height direction of the cutting platform 1, and ultimately drive the first support plate 2 to move along the height direction of the cutting platform 1.

[0044] Optionally, combined Figure 1 and Figure 3As shown, the driving component also includes a fourth support plate 15 and a third linear slide 16. The fourth support plate 15 is located above the cutting platform 1 along the height direction of the cutting platform 1. The third linear slide 16 is mounted on the fourth support plate 15 along the width direction of the cutting platform 1.

[0045] In this embodiment, the fourth support plate 15 supports the installation of the third linear slide 16, and the third linear slide 16 supports the installation of the third support plate 13. During use, controlling the third linear slide 16 moves the third support plate 13 along the width direction of the cutting platform 1, ultimately moving the first support plate 2 along the width direction of the cutting platform 1.
