[0029] Please refer to Figure 1-4 The following describes one embodiment of the skin-turning machine of the present utility model.

[0030] Please refer to Figure 1This application provides a shell flipping machine, including a frame 1, a feeding component 2, and a flipping mechanism 3. The flipping mechanism 3 includes a lifting component 31, a rotating component 32, and a flipping block 33. The feeding component 2 is disposed on the frame 1, the lifting component 31 is mounted on the frame 1, the lifting component 31 is driven to the rotating component 32 to move the rotating component 32 up and down, the rotating component 32 is driven to the flipping block 33 to rotate perpendicular to the conveying direction of the shell, and the flipping block 33 is used to flip the shell located on the feeding component 2. Specifically, during the feeding stage, the shell is conveyed by the feeding component 2 to the top of the flipping mechanism 3. The flipping mechanism 3 has lifting and rotating functions. In order to accurately align the feeding and flip 180°, the lifting component drives the rotating component to move up and down, so that the flipping block 33 accurately aligns with and receives the shell. Then, the rotating component 32 drives the flipping block 33 to rotate perpendicular to the conveying direction of the shell, so that the shell completes the 180° flip. This realizes the connection of the shell from feeding to flipping in the vertical space, reduces the space occupation, enables continuous and uninterrupted flipping, simplifies the production process and reduces costs, reduces the labor intensity of workers and improves work efficiency.

[0031] In another embodiment of this application, please refer to Figure 1 The feeding assembly 2 includes rollers 21 and first belts 22. Two rollers 21 are provided, rotatably mounted on the frame 1. Multiple first belts 22 are arranged parallel to each other and spaced apart. A turning block 33 can extend vertically upwards through the gaps in the first belts 22 to receive the leather casing. Specifically, multiple first belts 22 form a conveying structure around two rollers 21. The leather casing is supported by the first belts 22. The design of multiple parallel and spaced first belts 22 reduces the friction area between the leather casing and the conveying surface by providing multi-point support to the bottom of the casing, thus reducing the risk of surface scratches. The spaced arrangement allows the turning block 33 to extend upwards through the gaps, accurately aligning with and receiving the turned leather casing. It is also adaptable to leather casings of different thicknesses and widths, solving the problems of easy casing deviation and side wear in traditional single-belt conveying. The closed belt structure driven by the dual rollers 21 ensures stable conveying speed and avoids positioning deviations caused by uneven conveying during the feeding stage.

[0032] In another embodiment of this application, please refer to Figure 1 The feeding assembly 2 also includes a paper-pressing roller 23, which is fixedly connected to the frame 1 via a bracket 24. The paper-pressing roller 23 is positioned above the first belt 22. Specifically, there are two sets of paper-pressing rollers 23, located at the front and rear ends of the feeding assembly 2, respectively. During the conveying of the paper casing, they elastically press down to prevent the paper casing from bouncing or shifting due to high-speed conveying or its own warping, ensuring that the paper casing accurately enters the flipping block 33 of the flipping mechanism 3, thereby improving feeding stability and reducing the downtime failure rate.

[0033] In another embodiment of this application, please refer to Figure 3 The lifting assembly 31 includes a guide post 311, a guide sleeve 312, a movable plate 313, and a cylinder 315. The guide post 311 is slidably disposed inside the guide sleeve 312. The guide sleeve 312 is fixedly connected to the movable plate 313. The cylinder 315 is fixedly disposed on the movable plate 313. The movable plate 313 is fixedly connected to the fixed plate 314. The fixed plate 314 is fixedly connected to the frame 1. Specifically, the sliding cooperation between the guide post 311 and the guide sleeve 312 ensures smooth lifting action, avoids shaking of the tilting block 33 during lifting, and solves the problem of easy tilting caused by traditional single cylinder 315 drive. The cylinder 315 drive realizes controllable lifting stroke. The speed is adjusted by a solenoid valve, so that the tilting block 33 can accurately align with the height of the shell conveyed by the receiving assembly 2, ensuring that the shell falls smoothly into the tilting block 33 and reducing impact damage during docking.

[0034] In another embodiment of this application, please refer to Figure 3 The rotating assembly 32 includes a lifting plate 321, a vertical plate 322, a motor 323, a synchronous belt 324, a connecting shaft 325, and a synchronous pulley 326. The lifting plate 321 is fixedly connected to the end of the guide column 311 and the piston rod of the cylinder 315. The vertical plate 322 is arranged parallel to the length of the lifting plate 321 and is fixedly connected to the lifting plate 321. The vertical plate 322 is provided with a synchronous pulley 326 connected to the tilting block 33. Each vertical plate 322 is provided with a bearing hole for the connecting shaft 325 to pass through. The motor 323 is fixed on the lifting plate 321. The synchronous pulley 326 is fixedly sleeved on the output shaft of the motor 323. The synchronous pulley 326 is fixedly sleeved on the connecting shaft 325. The synchronous belt 324 is wound between the driving synchronous pulleys 326. The tilting block 33 is fixed at the end of the vertical plate 322. The motor 323 drives the connecting shaft 325 to rotate through the synchronous belt 324, thereby driving the tilting block 33 to rotate synchronously. Specifically, the motor 323 is located in the middle of the lifting plate 321. The synchronous pulley 326 on the output shaft of the motor 323 drives the synchronous pulley 326 on the connecting shaft 325. The synchronous pulley 326 on the connecting shaft 325 drives the synchronous pulley 326 on the vertical plate 322, causing the flipping block 33 to rotate. The synchronous belt 324 provides smooth transmission and high angular accuracy. The flipping block 33 is connected to the synchronous pulley 326 through the connecting shaft 325, ensuring stable torque during 180° flipping. This solves the problem of uneven clamping force causing deformation of the casing when flipping with traditional suction cups or grippers. The fixed structure between the vertical plate 322 and the lifting plate 321 enhances the overall rigidity of the rotating component 32, prevents vibration during high-speed flipping, and extends the service life of the equipment.

[0035] In another embodiment of this application, please refer to Figure 1-4It also includes a feeding assembly 4, which includes a second belt 41, a baffle 42, a scraper 43, and a pallet 44. The feeding assembly 4 is located at the end of the feeding assembly 2. The second belt 41 is rotatably mounted on the feeding assembly 4 for receiving and conveying the casing. The baffle 42 is used to block the casing. The scraper 43 is movably mounted on the pallet 44. The baffle 42 and the pallet 44 are horizontally movable on the feeding assembly 4. Specifically, the second belt 41 can adjust its conveying direction as needed and is horizontally installed on the flipping mechanism 3 to receive the flipped shells; the baffle 42 can be driven to rise and fall by a cylinder 315 or a motor 323, allowing the shells to pass when it rises and blocking them when it falls; the scraper 43 can move linearly along the guide rail to push the flipped shells without contact, pushing them to align with the baffle 42 or assisting them into the discharge assembly 5, thus avoiding scratches on the shell surface due to friction, especially on the printed surface and hot stamping layer; the scraper 43 driven by the cylinder 315 has controllable movement and is adaptable to shells of different sizes; the baffle 42 and the scraper 43 form a discharge guide, preventing the shells from deviating during discharge and ensuring accurate docking of the subsequent discharge assembly 5.

[0036] In another embodiment of this application, please refer to Figure 1-4 The feeding assembly 4 is also provided with a push bar 45 and a support column 46. The support column 46 is fixedly mounted on the push bar 45 and is correspondingly positioned to the hollow areas of the baffle 42 and the support plate 44. Specifically, when receiving materials, the support column 46 protrudes from the baffle 42 and the support plate 44 and provides support from the hollow area to receive the casing and prevent the casing from deforming during conveying.

[0037] In another embodiment of this application, please refer to Figure 1-4 Furthermore, the baffle 42 can also move vertically. Specifically, the vertical adjustability of the baffle 42 allows it to adapt to shells of different widths without the need to replace the baffle 42 component, thus overcoming the limitation of traditional fixed baffles 42 that can only adapt to a single specification; the slider moving structure enables precise positioning of the baffle 42, ensuring consistent guidance for shells of different sizes and improving the versatility of the equipment.

[0038] In another embodiment of this application, please refer to Figure 1-4 The system also includes a discharge assembly 5, which is located at the end of the feeding assembly 4. The discharge assembly 5 also includes a flow strip 51, which guides the casings to be discharged along a preset path. Specifically, after a certain number of casings are on the feeding assembly 4, the second belt 41 is rotated to transport the casings to the discharge assembly 5. The flow strip 51 reduces surface wear during casing discharge by using rolling friction instead of sliding friction, which is especially suitable for casings that are easily damaged, such as those that have undergone lamination or hot stamping. The guiding effect of the flow strip 51 ensures that the casings are discharged along the preset path, avoiding accumulation caused by gravity offset, making the connection to subsequent processes smoother and improving the continuity of the overall production line.

[0039] In another embodiment of this application, please refer to Figure 1 The frame 1 is also equipped with a control system 6, which is electrically connected to the feeding component 2, the flipping mechanism 3, the discharging component 4, and the discharging component 5. Specifically, the control system 6 realizes the automated linkage of each component, replacing manual operation.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
