Description

Technical Field

[0001] The invention relates to the technical field of peeling devices, in particular to a pumpkin vine skin removing device. Background Art

[0002] The vine growth stage is particularly crucial in the pumpkin's growth process. During this stage, the young vines and side shoots are tender and delicious, resembling a natural delicacy. Not only do they have a crisp texture, but they are also rich in nutrients and high in dietary fiber, making them a highly sought-after healthy vegetable on the table.

[0003] Compared with other common leafy vegetables, pumpkin vines have significant advantages. The investment cost of the planting process is relatively low, and the harvest period is long, which can bring stable income to growers for a long time, and the economic benefits are very considerable. However, the skin of pumpkin vines is covered with burrs, which seriously affect the eating experience. Currently, the method of removing burrs from the skin of pumpkin vines mainly relies on manual operation. Growers need to spend a lot of time and energy to tear off the skin of pumpkin vines one by one. This process is extremely cumbersome and inefficient, which seriously restricts the sales and large-scale production of pumpkin vines.

[0004] Currently, existing research focuses primarily on devices for peeling the peels of mature pumpkin fruits. However, the delicate, vine-like appearance of pumpkin vines makes conventional peeling equipment ineffective. Therefore, developing efficient equipment specifically suited for peeling pumpkin vines has become a critical challenge for the pumpkin industry. This is crucial for promoting the market distribution and large-scale production of pumpkin vines, and for improving the overall economic benefits of the pumpkin industry. Summary of the Invention

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figures 1 to 4 shown, this embodiment provides a pumpkin vine epidermis removing device, including a conveying structure, a cutting assembly, a peeling assembly and a transmission shaft 10; the conveying structure includes a first driving assembly 8, a first conveying body and a second conveying body, a conveying channel is formed between the first conveying body and the second conveying body, and the first driving assembly 8 is in transmission connection with at least one of the first conveying body or the second conveying body; the cutting assembly includes a cutting knife 3; the peeling assembly includes a peeling knife 9; the transmission shaft 10, along the axial direction of the transmission shaft 10, a through axial through hole is provided on the transmission shaft 10 to form a process cavity, the cutting knife 3 and the peeling knife 9 are both arranged on the transmission shaft 10 and the blade part extends into the process cavity; the transmission shaft 10 is in transmission connection with the second driving assembly 2 to drive the cutting knife 3 and the peeling knife 9 to rotate around the pumpkin vine, and the cutting assembly is located between the conveying structure and the peeling assembly. The pumpkin vine conveyed by the conveying structure enters from one end of the process cavity and completes the separation of the vine body and the epidermis when coming out from the other end of the process cavity.

[0033] In this specific embodiment, the first conveyor includes a first conveyor roller 1, and a plurality of anti-slip protrusions are provided on the surface of the first conveyor roller 1. The anti-slip protrusions are made of rubber. The anti-slip protrusions are in contact with the pumpkin vine, which can increase the friction between the first conveyor roller 1 and the pumpkin vine, so that the pumpkin vine advances at a stable speed.

[0034] The first driving assembly 8 includes a first driving motor, and the output shaft of the first driving motor is connected to the central axis of the first conveyor roller 1 through gear transmission, belt transmission or chain transmission, and the first conveyor roller 1 is driven by the first driving motor.

[0035] The middle diameter of the upper conveying pipe is smaller, and the edge diameter is larger. The pumpkin vine is restricted in the middle of the upper conveying pipe to prevent the pumpkin vine from falling off from the conveying channel.

[0036] In some specific embodiments, the middle part of the first conveyor roller 1 has a first diameter, and both ends have a second diameter, and the first diameter is smaller than the second diameter. The parts with larger diameters at both ends limit and block the pumpkin vine, so that the pumpkin vine can be restricted in the middle of the first conveyor roller 1 to prevent the pumpkin vine from falling off from the conveying channel. The first conveyor roller 1 can be arranged horizontally or vertically.

[0037] In another specific embodiment, the first conveyor roller 1 is arranged horizontally. The middle part of the first conveyor roller 1 transitions to both ends with a smooth curve; to prevent the pumpkin vine from swaying along the axial ends of the first conveyor roller 1, so that pumpkin vines of any diameter can advance in a straight line and enter the transmission shaft 10.

[0038] In some specific embodiments, the second conveyor can adopt a supporting plate 5, and the supporting plate 5 is used to support the pumpkin vine. The supporting plate 5 is connected to the adjusting mechanism. The adjusting mechanism is arranged between the supporting plate 5 and the frame 4. The adjusting mechanism includes an adjusting screw 7 and an adjusting nut 6; an adjusting hole is provided on the side of the supporting plate 5 away from the first conveyor. One end of the adjusting screw 7 extends into the adjusting hole, and the other end of the adjusting screw 7 passes through the frame 4 through the mounting hole. The adjusting nut 6 is threadedly connected to the adjusting screw 7, and the adjusting nut 6 is located at both ends of the mounting hole. By adjusting the position of the adjusting nut 6 on the adjusting screw 7, the distance between the end of the adjusting screw 7 and the first conveyor roller 1 is adjusted, thereby realizing the adjustment of the size of the conveying channel, so that the conveying channel can adapt to pumpkin vines of different diameters.

[0039] More specifically, the adjusting mechanism further includes an elastic member. The elastic member is located between one end of the adjusting screw 7 and the bottom of the adjusting hole and is sleeved on the adjusting screw 7. The elastic member adopts a spiral spring 11. The spiral spring 11 enables the supporting plate 5 to reciprocate within a certain range, so that the size of the conveying channel can be automatically adjusted according to the diameter of the pumpkin vine, improving the adaptability of the device.

[0040] In other specific embodiments, the second conveying body can also be a second conveying roller 12, and the surface of the second conveying roller 12 is provided with a plurality of anti-slip protrusions. An oblong hole is provided on the frame 4, and the central axis and the adjustment mechanism of the second conveying roller 12 are both located in the oblong hole. Pumpkin vines of different diameters exert different pressures on the second conveying roller 12. The second conveying roller 12 reciprocates in the oblong hole as the pressure changes, ensuring that the conveying channel can continuously clamp the pumpkin vines, thereby achieving uniform movement of the pumpkin vines and ensuring that the cutting knife 3 cuts uniform marks on the surface of the pumpkin vines, so that the peeling knife 9 can peel stably, avoiding the shaking of the peeling knife 9 caused by uneven cutting lines due to inconsistent pumpkin vine conveying speed, which is beneficial to improving the quality of the peeled vines.

[0041] In order to ensure that the pumpkin vines can move in a straight line and reduce the shaking of the pumpkin vines during transportation, the second conveying body is connected to the first drive assembly 8. At this time, in order to enable the first drive assembly 8 to adapt to the reciprocating motion of the second conveying body with the adjustment mechanism, the first drive assembly 8 adopts chain drive or belt drive, and a tensioning mechanism is provided so that the transmission belt or chain can maintain sufficient tension at any time to ensure that the first drive assembly 8 can reliably drive the first conveying roller 1 and the second conveying roller 12.

[0042] A structure that is transmission-connected to the second drive assembly 2 is provided on the outer wall of the transmission shaft 10 . The structure can be a gear, a sprocket, a pulley, or a synchronous belt. The specific structure type is selected according to the type of the second drive assembly 2 .

[0043] The second drive assembly 2 includes a second drive motor. The output shaft of the second drive motor is connected to the outer wall of the transmission shaft 10 through gear transmission, belt transmission or chain transmission, and the transmission shaft 10 is driven by the second drive motor.

[0044] Bearings are respectively provided between the first conveying body, the second conveying roller 12 and the transmission shaft 10 and the frame 4 to achieve rotation.

[0045] The cutting assembly also includes a cutting adjustment mechanism, which includes a cutting adjustment nut. The cutting knife 3 includes a cutting rod and a cutting blade. A through cutting hole is provided on the transmission shaft 10 along the radial direction of the transmission shaft 10. An anti-rotation structure is provided between the cutting rod and the cutting hole to prevent the cutting rod from rotating in the cutting hole, thereby ensuring that the cutting blade is perpendicular to the axial direction of the process chamber. The cutting adjustment nut is threadedly connected to the cutting rod, so that the length of the cutting blade extending into the process chamber can be adjusted by rotating the cutting adjustment nut, thereby adjusting the cutting depth of the pumpkin vine.

[0046] The cutting adjustment nut is arranged at one end of the cutting hole away from the process chamber, and a displacement limiting structure is set between the cutting adjustment nut and the transmission shaft 10, so that the cutting adjustment nut can only rotate along its own axis but cannot move linearly.

[0047] The peeling assembly further includes a peeling adjustment mechanism. The peeling adjustment mechanism includes a peeling adjustment nut. The peeling knife 9 includes a peeling knife rod 13 and a peeling blade 14. Along the radial direction of the transmission shaft 10, a through peeling hole is provided on the transmission shaft 10. An anti-rotation structure is provided between the peeling knife rod 13 and the peeling hole to prevent the peeling knife rod 13 from rotating in the peeling hole, ensuring that the peeling blade 14 is perpendicular to the axial direction of the process cavity. The peeling adjustment nut is threadedly connected to the peeling knife rod 13. Thus, by rotating the peeling adjustment nut, the length of the peeling blade 14 extending into the process cavity can be adjusted, and the peeling depth of the pumpkin vine can be adjusted.

[0048] The peeling adjustment nut is arranged at one end of the peeling hole away from the process cavity. A displacement limit structure is provided between the peeling adjustment nut and the transmission shaft 10, so that the peeling adjustment nut can only rotate along its own axis and cannot move linearly.

[0049] The blade part of the peeling knife 9 extends along the axial direction of the process cavity to form a scraping structure 15. The scraping structure 15 is inserted between the epidermis and the vine body to peel the epidermis, and can also cut the vine body, making the vine body have a uniform diameter. At the same time, the depression on the surface of the vine body can be removed, improving the aesthetics of the vine body and enhancing the customer's desire to purchase.

[0050] In order to prevent the peeled epidermis from continuing to wrap around the vine body, by controlling the rotation speed of the transmission shaft 10 and the conveying speed of the pumpkin vine by the conveying structure, the spiral knife marks formed after the cutting knife 3 cuts have a smaller pitch. For example, the pitch is controlled within 1 centimeter. Then, the epidermis is scraped by the scraping structure 15. The epidermis breaks along the longitudinal fiber direction by its own gravity or friction with the vine body, forming a strip structure with a shorter length, and the epidermis naturally falls off and separates from the vine body. The pumpkin vine can also be pre-cut into a certain length, for example, cut into pumpkin vine segments with a length of 30 to 100 centimeters. After peeling, even if the epidermis wraps around the vine body, it is easy to pull the vine body out of the wrapped epidermis.

[0051] The anti-rotation structure may include an anti-rotation limiting piece. The anti-rotation limiting piece is connected to the cutting hole or the peeling hole by interference fit, welding or bonding. Along the radial direction of the transmission shaft 10, at least one anti-rotation surface is provided on the anti-rotation limiting piece, and at least one mating surface corresponding to the anti-rotation surface is provided on the outer wall of the cutting knife rod or the peeling knife rod 13, and the mating surface contacts and limits the anti-rotation surface.

[0052] The inner wall shape of the anti-rotation limiting piece can be polygonal, such as quadrilateral, hexagon, octagon. The outer wall of the cutting tool bar or the peeling tool bar 13 is processed into a polygon with corresponding dimensions and shape. The cutting tool bar or the peeling tool bar 13 is limited by the polygon to prevent it from rotating, so as to facilitate the threaded connection between the cutting adjustment nut or the peeling adjustment nut and the cutting tool bar or the peeling tool bar 13. The inner wall of the anti-rotation limiting piece can also be set to be semi-circular or multi-semi-circular, and the outer wall of the cutting tool bar or the peeling tool bar 13 is processed into a semi-circular or multi-semi-circular shape with corresponding dimensions and shape.

[0053] The displacement limiting structure includes a limiting cover. The limiting cover is threadedly connected to the cutting hole or the peeling hole. One end of the limiting cover facing the process cavity forms a rotating installation cavity. A through hole that contracts axially towards the rotating installation cavity is provided at one end of the rotating installation cavity away from the process cavity. The diameter of the part of the cutting adjustment nut or the peeling adjustment nut located in the rotating installation cavity is larger, and the diameter of the part passing through the through hole is smaller. Thus, the cutting adjustment nut or the peeling adjustment nut is rotatably arranged in the rotating installation cavity, and the cutting adjustment nut or the peeling adjustment nut can be rotated by rotating the part passing through the through hole to realize the adjustment of the size of the cutting blade or the peeling blade 14 extending into the process cavity.

[0054] The limiting cover can also be fixed by interference fit or bonding connection, as long as it can realize the rotation of the cutting adjustment nut or the peeling adjustment nut but cannot perform linear movement.

[0055] The first driving motor and the second driving motor can also use an air pump, as long as it can provide the power of rotation and ensure the cleanliness of the surrounding environment without polluting the pumpkin vine.
