[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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

[0022] See Figures 1 to 4 As shown, a novel pumpkin peeling machine includes a frame 1, a worktable 2 fixed to the top surface of the frame, a support platform 3 on the top of the frame, a motor base 4 directly above the worktable on the top of the support platform, a drive motor fixed inside the motor base, a supporting upper shaft 5 fixed on the main shaft of the drive motor, and a pressure plate 6 fixed on the bottom surface of the supporting upper shaft. In this embodiment, the drive motor is a conventional structure of the prior art, so it is not described in detail. It mainly uses the pressure plate to drive the pumpkin to rotate. The support platform is mainly used to realize the lifting and lowering of the peeling blade, thereby realizing the peeling operation of the pumpkin 19 at different positions.

[0023] In this embodiment, a lifting structure 7 and a supporting lower shaft 8 are fixed inside the frame, with the supporting lower shaft located directly below the pressure plate. Both the lifting structure and the supporting lower shaft can be raised and lowered. When the lifting structure is raised and lowered, it works with the supporting lower shaft to support the pumpkin, preventing the pumpkin from tilting or shaking. After the pumpkin is clamped, the lifting structure lowers again, thereby avoiding affecting the peeling operation of the lower part of the pumpkin and improving the comprehensiveness and effectiveness of peeling.

[0024] In this embodiment, a vertical clearance groove 9 is provided on the side of the support platform, and a lifting cylinder 10 is provided inside the support platform. An adjusting cylinder 11 is provided on the piston shaft of the lifting cylinder, and a peeling blade 12 is fixed on the adjusting cylinder. The peeling blade is pressed against the surface of the pumpkin under the action of the adjusting cylinder. In this embodiment, the adjusting cylinder is a miniature cylinder, which can reduce its space occupation and drive the position adjustment of the peeling blade, which can meet the peeling operation of different positions on the pumpkin surface and ensure the effectiveness and uniformity of peeling.

[0025] In this embodiment, the lifting structure includes a lifting cylinder, several support rods 71 ​​fixed to the piston shaft of the lifting cylinder, and a circular lifting plate 72 fixed to the top of the support rods; several support columns 73 are provided on the top surface of the circular lifting plate. A support plate 13 is fixed to the top of the lower support shaft, the support plate is located at the center of the circular lifting plate, and a control cylinder connected to the lower support shaft is fixed inside the frame; the control cylinder and the lifting structure rise and support the bottom surface of the pumpkin, the lifting structure descends, and the pumpkin is clamped and positioned by the support plate and the pressure plate. The lifting cylinder and the control cylinder are not shown, but are mainly used to support the lifting action of the lower shaft and the support rods;

[0026] Furthermore, in this embodiment, a foot switch 14 is provided at the lower part of the frame. This is mainly for control via foot pedal, improving the convenience of control operation.

[0027] To facilitate inspection and maintenance operations, a lower inspection door 15 is provided on the back of the frame, and an upper inspection door 16 is provided on the back of the support platform. This facilitates the inspection and maintenance of the internal structure and improves operational efficiency.

[0028] In this embodiment, the bottom of the frame is equipped with casters 17 and lifting support feet 18 for easy movement and positioning.

[0029] In this embodiment, it is suitable for flat, disc-shaped pumpkins with a diameter-to-axis ratio greater than 1. The peeling blade can peel along the outer surface of the flat pumpkin, minimizing flesh loss during peeling. The peeling blade's rotation center position can be automatically adjusted according to the size and height of the pumpkin being processed via a cylinder, eliminating manual operation, saving manpower, and improving processing efficiency. It can process pumpkins with a maximum diameter of 30cm and a height of 20cm. Due to the relatively heavy weight of a single pumpkin, a lifting structure is incorporated to ensure stable lifting. After lifting, the lifting structure... The descent mechanism does not interfere with the peeling process at the bottom of the pumpkin. After peeling, the lifting structure rises again to complete the descent. It uses standard, universal parts, facilitating inspection, maintenance, and replacement. One-button operation reduces labor intensity by requiring minimal human intervention. Adjusting the cylinder in conjunction with the peeling blade adapts to the pumpkin's height, ensuring that the remaining peel area at the top and bottom center is essentially the same, guaranteeing a good peeling effect. Furthermore, its purely mechanical structure avoids emergencies caused by electromagnetic interference or environmental conditions, improving safety and stability. It also facilitates maintenance and cleaning, making it highly versatile.

[0030] The operating instructions state that before turning on the machine, confirm that the air source and power supply are properly connected. In particular, the air pressure for clamping the upper support shaft 5 and the lower support shaft 8 must be strictly set according to the air pressure values ​​in the operating instructions; otherwise, the pumpkin may be crushed.

[0031] Check if the peeler blade is intact and if the opening is suitable for the thickness of the pumpkin to be peeled; check if the clamping is normal; check if the joints move smoothly.

[0032] Check that the emergency stop switch has been reset, run the machine without load, and confirm that all functions are operating normally.

[0033] Cut off the stem of the pumpkin as required, but do not damage the flesh at the top center; place the pumpkin on the lifting mechanism.

[0034] Press the foot switch, and the pumpkin machine will automatically rise to the pressure plate position and continue to press.

[0035] The lifting mechanism automatically lowers after the pumpkin is firmly pressed down.

[0036] As the spindle rotates, the peeling blade, propelled by the mini cylinder, presses against the pumpkin's surface, and the peeling process begins.

[0037] The peeler rotates to the bottom of the pumpkin, the peeling is finished, and the mini cylinder retracts; the peeler leaves the pumpkin and rotates back to its initial position.

[0038] The lifting mechanism extends again, supporting the lower shaft to descend; the pumpkin is released, falls onto the round support of the lifting mechanism, and returns to its lowest position along with the lower shaft.

[0039] Manually remove the peeled pumpkin and place the next pumpkin on the lifting mechanism, repeating the above steps.

[0040] This invention has several advantages: Its structure is rationally designed, featuring a lifting structure and a supporting lower shaft. The pumpkin is placed on the lifting structure and supported lower shaft, and then lifted upwards. A pressure plate clamps and positions the pumpkin. A drive motor rotates the pressure plate, and the position of the peeling blade is controlled. Simultaneously, an adjustable cylinder raises and lowers the peeling blade, thus completing the peeling process on the entire pumpkin surface. This not only improves peeling efficiency but also makes operation convenient, enhancing peeling quality and effectiveness, and has strong applicability.

[0041] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
