Description

Technical Field

[0001] This invention belongs to the field of food processing technology, and in particular relates to a device and method for peeling glutinous yam. Background Technology

[0002] Glutinous yam, a nutritious and delicious food with both medicinal and culinary uses, is widely applied in food processing and culinary arts. Peeling is a crucial preliminary step in glutinous yam processing, directly impacting the quality of subsequent products, processing efficiency, and food safety. However, current glutinous yam peeling technologies still face several unresolved issues:

[0003] Limitations of manual peeling: Traditional manual peeling often uses tools such as scrapers and peelers, which is not only labor-intensive and inefficient, making it difficult to meet the needs of large-scale processing, but also easy to scratch hands due to improper operation; at the same time, manual peeling has poor thickness uniformity, which can easily lead to over-peeling in some areas, resulting in waste of fruit pulp, or residual peel in some areas, affecting product quality. In addition, the sticky sap on the surface of glutinous yam can easily cause hand discomfort, further reducing the convenience of operation.

[0004] The shortcomings of existing mechanical peeling techniques:

[0005] Blade-type peeling equipment: Peeling is achieved through the cutting action of rigid blades. However, glutinous yam is soft and the flesh is delicate. Rigid blades can easily cause cutting damage to the yam itself, resulting in broken flesh and loss of juice. At the same time, it cannot adapt to the natural uneven structure on the surface of the yam. Peeling is easily left in the uneven areas or it is over-cut.

[0006] Drum-type peeling equipment: Peeling is achieved by the relative friction between the friction medium on the inner wall of the drum and the yam. The peeling efficiency is low, and for glutinous yams with obvious surface bumps, the friction force is difficult to cover evenly, resulting in poor peeling. At the same time, the friction process can easily cause wear and tear on the surface of the yam and damage to its shape.

[0007] Insufficient coordination between clamping and cutting: Existing machines mostly use a fixed clamping method, which creates a blind spot for peeling at the clamping point. As a result, the skin of the glutinous yam cannot be effectively removed from the clamping area at both ends of the yam, requiring secondary processing and increasing the processing steps.

[0008] Lack of tension adjustment: The cutting tension of existing wire-cutting peeling equipment is mostly a fixed value, which cannot be adjusted in real time according to the unevenness of the yam surface. When encountering raised parts, insufficient tension leads to incomplete peeling, while excessive tension when encountering concave parts can easily damage the flesh. In addition, the cutting line is prone to breakage due to impurities or tension imbalance, which shortens its service life.

[0009] Disconnect between detection and adjustment: The lack of a real-time detection mechanism for the surface contour of yams makes it impossible to dynamically adapt to the surface conditions of different yams, resulting in poor equipment versatility and difficulty in meeting diverse processing needs.

[0010] Impurity interference: If the mud and impurities attached to the surface of the glutinous yam are not cleaned in time, they will not only wear down the cutting tools and shorten the service life of the equipment, but also affect the recognition accuracy of the detection element, causing the peeling parameters to be adjusted inaccurately, and further reducing the peeling effect.

[0011] In summary, existing peeling technologies suffer from problems such as low efficiency, incomplete peeling, easy damage to the yam itself, high labor intensity, and poor versatility, making it difficult to meet the needs of large-scale, high-quality glutinous yam processing. Therefore, developing a highly adaptable, thorough, minimally damaging, and efficient glutinous yam peeling device and method is of great practical significance. Summary of the Invention

[0012] The purpose of this invention is to address the problems mentioned in the background art by providing a glutinous yam peeling device and method that employs a line-cut peeling method, combines a visual sensor with a tension adjustment mechanism for closed-loop control, and uses a visual sensor to collect real-time data on the surface contour of the glutinous yam.

[0013] To achieve the above objectives, the present invention adopts the following technical solutions:

[0014] A device for peeling glutinous yam, comprising:

[0015] A processing platform, wherein a horizontally sliding mounting ring is provided on the top of the processing platform;

[0016] A wire-cutting peeling mechanism is mounted on an mounting ring and is used to peel glutinous yam by wire cutting. The wire-cutting peeling mechanism includes a fixed plate fixedly connected to the inner wall of the mounting ring, a rotating shaft rotatably connected to the fixed plate, a fixed take-up roller mounted on the rotating shaft through a spline shaft and a spline groove, a rotating ring rotatably connected to the mounting ring, and a movable take-up roller rotatably connected to the rotating ring.

[0017] A cutting line is provided between the fixed winding roller and the movable winding roller, and the cutting line can be wrapped around the periphery of the glutinous yam to peel it.

[0018] A mounting block is fixedly connected to the mounting ring, and a drive gear is rotatably connected to the mounting block. The circumferential sidewall of the rotating ring is provided with annular tooth grooves that mesh with the drive gear. A first motor for controlling the rotation of the drive gear is fixedly connected to the mounting block.

[0019] A torsion spring is provided between the rotating ring and the movable take-up roller to apply a certain tension force to the cutting line during the cutting process to ensure the peeling effect.

[0020] The tension adjustment mechanism is located between the fixed take-up roller and the fixed plate, and is used to adjust the tension of the cutting line in real time according to the unevenness of the glutinous yam surface.

[0021] Preferably, the tension adjustment mechanism includes an electromagnetic spring disposed between the fixed take-up roller and the fixed plate, and a plurality of vision sensors are provided on the inner wall of the mounting ring, the plurality of vision sensors being electrically connected to the electromagnetic spring.

[0022] Preferably, two fixing blocks are fixedly connected to the upper end of the processing platform, and a lead screw is rotatably connected between the two fixing blocks. A movable plate is threaded onto the lead screw, and the movable plate is slidably connected to the upper end of the processing platform in the horizontal direction. The mounting ring is fixedly connected to the movable plate, and a second motor for driving the lead screw is fixedly connected to one of the fixing blocks.

[0023] Preferably, the processing platform is provided with clamping mechanisms at both sides of the mounting ring. The clamping mechanism includes two extension plates fixedly connected to the upper end of the processing platform. A rotating rod is rotatably connected to each of the two extension plates. A crescent-shaped clamping block is fixedly connected to the side of the rotating rod closest to the mounting ring.

[0024] Preferably, a transmission mechanism is provided between the mounting ring and the clamping mechanism. When the ring moves to the side of the clamping mechanism during the cutting process, it automatically drives the clamping mechanism on that side to release the clamping mechanism on the glutinous yam, thereby avoiding obstruction to the cutting process and preventing incomplete cutting.

[0025] Preferably, the transmission mechanism includes a transmission plate fixedly connected to the upper end of the mounting ring, a guide wheel rotatably connected to the transmission plate, transmission gears fixedly connected to two rotating rods on the same side, vertical racks meshing on the sides of the two transmission gears that are far apart from each other, the two vertical racks being fixedly connected by a connecting rod, a C-shaped rod fixedly connected to the upper end of the connecting rod, and an inclined push plate fixedly connected to the side wall of the C-shaped rod away from the connecting rod.

[0026] Preferably, when the guide wheel moves closer to the clamping mechanism on either side, it abuts against the inclined push plate on that side and pushes it upward.

[0027] Preferably, a limiting rod is fixedly connected to the upper end of the processing platform, the limiting rod is slidably connected to the connecting rod, and a limiting sleeve is fixedly connected to the limiting rod to prevent the connecting rod from slipping.

[0028] A method for peeling glutinous yam using the above-mentioned glutinous yam peeling device includes the following steps:

[0029] S1. Pre-treatment preparation: Clean the surface of the glutinous yam to be peeled, remove the dirt and impurities attached to the surface, and avoid impurities affecting the service life of the cutting line and the detection accuracy of the vision sensor; place the pre-treated glutinous yam horizontally between the two clamping mechanisms of the processing platform, so that the axis of the glutinous yam is collinear with the central axis of the mounting ring.

[0030] S2. Clamping and fixing: The two crescent-shaped clamping blocks on both sides are driven to rotate relative to each other by the rotating rod, so that the two crescent-shaped clamping blocks abut against the outer peripheral walls of the two ends of the glutinous yam respectively, so as to achieve coaxial clamping and fixing of the glutinous yam and ensure that the glutinous yam does not shift or rotate during the peeling process;

[0031] S3. Tension Initialization Adjustment: Activate multiple vision sensors on the inner wall of the mounting ring. The vision sensors collect real-time contour data of the glutinous yam surface and identify the surface unevenness distribution. Based on the initial contour data collected by the vision sensors, the electromagnetic spring in the tension adjustment mechanism automatically adjusts the extension and retraction amount. Together with the torsion spring between the fixed winding roller and the moving winding roller, the cutting line is in an initial tension state, and the initial contact pressure between the cutting line and the glutinous yam surface is matched.

[0032] S4. Thread cutting and peeling operation:

[0033] Start the first and second motors:

[0034] The first motor drives the drive gear to rotate. The drive gear meshes with the annular tooth groove on the side of the rotating ring to drive the rotating ring to rotate. The rotating ring drives the moving take-up roller to rotate synchronously, so that the cutting line between the fixed take-up roller and the moving take-up roller makes a circular motion around the glutinous yam and surrounds and closely adheres to the side wall of the glutinous yam.

[0035] The second motor drives the lead screw to rotate, and the lead screw drives the threaded moving plate to slide horizontally along the processing platform. The moving plate drives the mounting ring and the wire cutting peeling mechanism to move at a constant speed along the axial direction of the glutinous yam, so as to realize axial peeling.

[0036] During the peeling process, the visual sensor continuously monitors the changes in the surface of the glutinous yam and sends adjustment signals to the electromagnetic spring in real time. The electromagnetic spring dynamically extends and retracts to adjust the position of the fixed take-up roller. Combined with the elastic force of the torsion spring, the tension of the cutting line is adjusted in real time to ensure that the uneven parts can be effectively peeled without damaging the yam itself.

[0037] S5. Automatic clamping avoidance:

[0038] When the mounting ring drives the guide wheel on the transmission plate to move horizontally with the moving plate, and the guide wheel approaches the clamping mechanism on either side, the guide wheel abuts against the inclined push plate on that side and pushes it upward along the inclined surface; the inclined push plate drives the connecting rod to slide upward along the limit rod through the C-shaped rod, and the connecting rod drives the vertical racks on both sides to rise synchronously. The vertical racks mesh with the transmission gear to drive the rotating rod to rotate, and the rotating rod drives the crescent-shaped clamping block to rotate away from the glutinous yam, releasing the clamping on that end of the glutinous yam and avoiding obstructing the axial movement of the cutting line;

[0039] When the mounting ring drives the guide wheel away from the clamping mechanism on this side, the guide wheel separates from the inclined push plate, the connecting rod resets along the limit rod under the action of gravity, the vertical rack drives the transmission gear to rotate in the opposite direction, the crescent-shaped clamping block resets and re-clamps the glutinous yam, ensuring the stability of the subsequent peeling process;

[0040] S6. Peeling complete and repositioning:

[0041] When the mounting ring moves to the other end along the axis of the glutinous yam and the vision sensor detects that the entire surface of the glutinous yam has been peeled, the first motor, the second motor and the vision sensor are turned off in sequence; the rotating rods on both sides are driven to rotate in the opposite direction, so that the crescent-shaped clamping block is completely released and the peeled glutinous yam is taken out; finally, the electromagnetic spring and the torsion spring are controlled to reset, and the mounting ring moves in the opposite direction along the screw to the initial position, completing one peeling operation.

[0042] Compared with existing technologies, the advantages of this glutinous yam peeling device and method are:

[0043] Thorough peeling and adaptable to uneven surfaces: This invention employs a wire-cutting peeling method, combined with closed-loop control of a visual sensor and a tension adjustment mechanism. The visual sensor collects real-time data on the surface contour of the yam, while an electromagnetic spring and a torsion spring work together to dynamically adjust the tension of the cutting line—the torsion spring provides basic tension, and the electromagnetic spring precisely fine-tunes the position of the fixed take-up roller according to changes in surface unevenness, ensuring that the cutting line always adheres tightly to the yam surface. Effective peeling can be achieved on both raised and recessed areas, completely solving the problems of poor adaptability to uneven surfaces and residual peel layer in traditional equipment.

[0044] To avoid damage to the yam and ensure product quality: The tension adjustment of the cutting line is always aimed at "adapting to the contact pressure". Through real-time feedback from the visual sensor and flexible adjustment of the double springs, the problem of pulp breakage and juice loss caused by rigid cutting or fixed tension is avoided, so as to preserve the complete shape and nutritional components of the yam to the greatest extent and improve product quality.

[0045] Eliminating peeling blind spots and achieving full surface coverage: Through the linkage design of the transmission mechanism and the clamping mechanism, when the mounting ring moves the cutting line to the side of the clamping mechanism, the guide wheel triggers the tilting push plate, and the clamping block is automatically released through rack and pinion transmission, avoiding the clamping part from obstructing the cutting; after the cutting line moves away, the clamping block automatically resets and re-fixes under the action of gravity, which not only ensures the stability of the yam during the peeling process, but also completely eliminates the peeling blind spots at both ends caused by traditional fixed clamping, achieving peeling without residue on the entire surface of the glutinous yam.

[0046] High processing efficiency and reduced labor intensity: This invention adopts a composite peeling mode of "circumferential ring cutting + axial uniform speed progressive". The first motor drives the cutting line to rotate at high speed around the circumference of the yam, and the second motor drives the mounting ring to move at a uniform speed along the axis. The two work together to achieve efficient full-surface coverage, and the processing efficiency is far higher than manual peeling and traditional roller peeling equipment. At the same time, the equipment has a high degree of automation, requiring only pre-processing and placement and subsequent material handling, which greatly reduces the labor intensity of operators and meets the needs of large-scale processing.

[0047] Reliable structure and easy operation: The linkage design of each mechanism is compact and logically clear. The transmission mechanism does not require an additional power source. It relies on the movement of the mounting ring to achieve automatic triggering of clamping and avoidance, reducing equipment complexity and energy consumption. The coaxial clamping design ensures that the yam does not shift or rotate during the peeling process, further ensuring the uniformity of peeling. The equipment reset is automated. After a single operation is completed, the electromagnetic spring, torsion spring, mounting ring and other components automatically return to their initial positions. The operation process is simple and has a low learning threshold.

[0048] Extending equipment lifespan and enhancing versatility: The pretreatment step, combined with the precise detection of vision sensors, reduces the wear and tear on the cutting line caused by dirt and impurities, as well as interference with detection accuracy, thus extending the service life of the cutting line and the stable operation cycle of the equipment. At the same time, the dynamic tension adjustment and coaxial clamping design can adapt to glutinous yams of different thicknesses and surface irregularities, eliminating the need for frequent adjustments to equipment parameters. This wide range of applications enhances the practicality and economy of the equipment. Attached Figure Description

[0063] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0064] Example: Refer to Figures 1 to 5 A device for peeling glutinous yam, comprising:

[0065] The processing platform 1 has a horizontally sliding mounting ring 11 on its upper part;

[0066] The wire-cutting peeling mechanism 2 is set on the mounting ring 11 and is used to peel the glutinous yam by wire cutting. The wire-cutting peeling mechanism 2 includes a fixed plate 21 fixedly connected to the inner wall of the mounting ring 11, a rotating shaft 22 rotatably connected to the fixed plate 21, a fixed take-up roller 23 installed on the rotating shaft 22 through a spline shaft and a spline groove, a rotating ring 24 rotatably connected to the mounting ring 11, and a movable take-up roller 25 rotatably connected to the rotating ring 24.

[0067] A cutting line 26 is provided between the fixed take-up roller 23 and the movable take-up roller 25. The cutting line 26 can be wrapped around the periphery of the glutinous yam to peel it.

[0068] Mounting block 3 is fixedly connected to mounting ring 11, driving gear 31 is rotatably connected to mounting block 3, and annular tooth groove 32 that meshes with driving gear 31 is provided on the peripheral side wall of rotating ring 24. A first motor 33 for controlling the rotation of driving gear 31 is fixedly connected to mounting block 3.

[0069] A torsion spring is provided between the rotating ring 24 and the movable take-up roller 25 to apply a certain tension force to the cutting line 26 during the cutting process to ensure the peeling effect;

[0070] The tension adjustment mechanism 4 is located between the fixed take-up roller 23 and the fixed plate 21. It is used to adjust the tension of the cutting line 26 in real time according to the unevenness of the glutinous yam surface. The tension adjustment mechanism 4 includes an electromagnetic spring 41 located between the fixed take-up roller 23 and the fixed plate 21. Multiple vision sensors are provided on the inner wall of the mounting ring 11. The multiple vision sensors are electrically connected to the electromagnetic spring 41.

[0071] The tension adjustment mechanism 4 adapts to the uneven surface of the yam by using a line cutting method. A visual sensor, as the core detection unit, captures real-time contour data of the glutinous yam surface, providing a basis for tension adjustment. An electromagnetic spring 41 and a torsion spring form a dual adjustment structure. The torsion spring provides the basic tension, while the electromagnetic spring 41 dynamically fine-tunes based on sensor signals, achieving a closed-loop control of "detection-feedback-adjustment." This ensures that the cutting line 26 can conform to the uneven surface for peeling without damaging the yam due to excessive tension.

[0072] Two fixed blocks 5 are fixedly connected to the upper end of the processing platform 1. A lead screw 51 is rotatably connected between the two fixed blocks 5. A movable plate 52 is threadedly connected to the lead screw 51. The movable plate 52 is slidably connected to the upper end of the processing platform 1 in the horizontal direction. The mounting ring 11 is fixedly connected to the movable plate 52. A second motor 53 for driving the lead screw 51 is fixedly connected to one of the fixed blocks 5.

[0073] The cooperation between the lead screw 51 and the moving plate 52 enables the smooth axial movement of the mounting ring 11, providing a power basis for the "axial progression" of the wire cutting peeling, ensuring that the cutting line 26 can evenly cover the entire surface along the axial direction of the glutinous yam. Combined with the circumferential circular motion of the cutting line 26, a composite peeling mode of "circumferential circular cutting + axial uniform speed advancement" is formed, which improves peeling efficiency and uniformity, and provides stable movement trajectory support for the subsequent triggering of the automatic clamping and avoidance mechanism.

[0074] Clamping mechanisms 6 are provided on both sides of the mounting ring 11 on the processing platform 1. The clamping mechanism 6 includes two extension plates 61 fixedly connected to the upper end of the processing platform 1. Rotating rods 62 are rotatably connected to both extension plates 61. A crescent-shaped clamping block 63 is fixedly connected to the side of the rotating rod 62 closest to the mounting ring 11.

[0075] The crescent-shaped clamping block 63 conforms to the arc-shaped structure of the outer wall of the glutinous yam, which can not only achieve stable coaxial clamping and prevent the yam from shifting or rotating during peeling, but also achieve rapid switching of clamping state through the rotation of the rotating rod 62, providing a structural basis for "clamping area transfer" and solving the problem that the clamping area cannot be peeled due to traditional fixed clamping.

[0076] A transmission mechanism 7 is provided between the mounting ring 11 and the clamping mechanism 6. When the cutting line 26 moves to the side of the clamping mechanism 6 during the cutting process, the clamping mechanism 6 on that side is automatically driven to release the clamping mechanism 6 on the glutinous yam, thereby avoiding obstruction to the cutting process and causing incomplete cutting.

[0077] The transmission mechanism 7, through a mechanical linkage structure, converts the axial movement of the mounting ring 11 into the opening and closing action of the clamping mechanism 6. Without the need for an additional power source, it achieves the linkage effect of "movement triggering - automatic avoidance", ensuring that the cutting line 26 can extend to the clamping area at both ends of the glutinous yam, eliminating blind spots in peeling and improving the overall peeling.

[0078] The transmission mechanism 7 includes a transmission plate 71 fixedly connected to the upper end of the mounting ring 11. A guide wheel 72 is rotatably connected to the transmission plate 71. Transmission gears 73 are fixedly connected to two rotating rods 62 on the same side. Vertical racks 74 mesh on the side of the two transmission gears 73 that are far apart from each other. The two vertical racks 74 are fixedly connected to each other by a connecting rod 75. A C-shaped rod 76 is fixedly connected to the upper end of the connecting rod 75. An inclined push plate 77 is fixedly connected to the side wall of the C-shaped rod 76 that is far away from the connecting rod 75.

[0079] Specifically, when the guide wheel 72 moves closer to the clamping mechanism 6 on either side, it abuts against the inclined push plate 77 on that side and pushes it upward, ensuring that the clamping mechanism on that side releases in advance when the cutting line 26 is about to reach the clamping area, thus avoiding interference between the cutting line and the clamping block. At the same time, the rotational characteristics of the guide wheel reduce the frictional resistance with the inclined push plate, ensuring a smooth and stable triggering process, without affecting the uniform movement of the mounting ring 11, and ensuring the continuity of the peeling process.

[0080] Specifically, a limiting rod 8 is fixedly connected to the upper end of the processing platform 1. The limiting rod 8 is slidably connected to the connecting rod 75, and a limiting sleeve is fixedly connected to the limiting rod 8 to prevent the connecting rod 75 from slipping. The limiting rod 8 provides guidance and constraint for the vertical movement of the connecting rod 75, preventing the connecting rod from deviating during the up and down sliding process, ensuring the meshing accuracy of the vertical rack 74 and the transmission gear 73, and ensuring the accuracy of the opening and closing action of the clamping mechanism. The limiting sleeve prevents the rack and gear from disengaging due to excessive sliding of the connecting rod 75 under gravity, ensuring the stability and service life of the transmission mechanism, and providing structural protection for the cyclic operation of the automatic clamping avoidance mechanism.

[0081] The transmission mechanism 7, through the force transmission path of "guide wheel 72 - inclined push plate 77 - C-shaped rod 76 - connecting rod 75 - vertical rack 74 - transmission gear 73 - rotating rod 62", converts the horizontal movement of the mounting ring 11 into the rotational motion of the rotating rod 62, thereby realizing the automatic opening and closing of the clamping block. The inclined surface design of the inclined push plate 77 efficiently converts the horizontal thrust of the guide wheel 72 into the upward force of the vertical rack 74. The meshing of the transmission gear and the rack ensures the accuracy of motion transmission. The connecting rod 75 realizes the synchronous action of the vertical racks 74 on both sides, ensuring the consistency of the opening and closing of the clamping block and further optimizing the reliability of clamping and avoidance.

[0082] A method for peeling glutinous yam using the above-mentioned glutinous yam peeling device includes the following steps:

[0083] S1. Pre-treatment preparation: Clean the surface of the glutinous yam to be peeled, remove the dirt and impurities attached to the surface, and avoid impurities affecting the service life of the cutting line and the detection accuracy of the vision sensor; place the pre-treated glutinous yam horizontally between the two clamping mechanisms 6 of the processing platform 1, so that the axis of the glutinous yam is collinear with the central axis of the mounting ring 11.

[0084] S2. Clamping and fixing: The two crescent-shaped clamping blocks 63 on both sides are driven to rotate relative to each other by the rotating rod 62, so that the two crescent-shaped clamping blocks 63 respectively abut against the outer peripheral walls of the two ends of the glutinous yam, thereby achieving coaxial clamping and fixing of the glutinous yam and ensuring that the glutinous yam does not shift or rotate during the peeling process;

[0085] S3. Tension initialization adjustment: Activate multiple vision sensors on the inner wall of the mounting ring 11. The vision sensors collect real-time contour data of the glutinous yam surface and identify the surface unevenness distribution. Based on the initial contour data collected by the vision sensors, the electromagnetic spring 41 in the tension adjustment mechanism 4 automatically adjusts the extension and retraction amount. In conjunction with the torsion spring between the fixed take-up roller 23 and the movable take-up roller 25, the cutting line 26 is in an initial tension state, and the initial contact pressure between the cutting line 26 and the glutinous yam surface is matched.

[0086] S4. Thread cutting and peeling operation:

[0087] Start the first motor 33 and the second motor 53:

[0088] The first motor 33 drives the drive gear 31 to rotate. The drive gear 31 drives the rotating ring 24 to rotate by meshing with the annular tooth groove 32 on the periphery of the rotating ring 24. The rotating ring 24 drives the movable take-up roller 25 to rotate synchronously, so that the cutting line 26 between the fixed take-up roller 23 and the movable take-up roller 25 makes a circular motion around the glutinous yam and surrounds and closely adheres to the periphery of the glutinous yam.

[0089] The second motor 53 drives the lead screw 51 to rotate. The lead screw 51 drives the threaded moving plate 52 to slide horizontally along the processing platform 1. The moving plate 52 drives the mounting ring 11 and the wire cutting peeling mechanism 2 to move at a constant speed along the axial direction of the glutinous yam, so as to realize axial peeling.

[0090] During the peeling process, the visual sensor continuously monitors the changes in the unevenness of the glutinous yam surface and sends adjustment signals to the electromagnetic spring 41 in real time. The electromagnetic spring 41 dynamically extends and retracts to adjust the position of the fixed take-up roller 23. In conjunction with the elastic force of the torsion spring, the tension of the cutting line 26 is adjusted in real time to ensure that the unevenness can be effectively peeled without damaging the yam body.

[0091] S5. Automatic clamping avoidance:

[0092] When the mounting ring 11 drives the guide wheel 72 on the transmission plate 71 to move horizontally with the moving plate 52, and the guide wheel 72 approaches the clamping mechanism 6 on either side, the guide wheel 72 abuts against the inclined push plate 77 on that side and pushes it upward along the inclined surface; the inclined push plate 77 drives the connecting rod 75 to slide upward along the limiting rod 8 through the C-shaped rod 76, and the connecting rod 75 drives the vertical racks 74 on both sides to rise synchronously. The vertical racks 74 mesh with the transmission gear 73 to drive the rotating rod 62 to rotate, and the rotating rod 62 drives the crescent-shaped clamping block 63 to rotate away from the glutinous yam, releasing the clamping on that end of the glutinous yam and avoiding obstructing the axial movement of the cutting line 26;

[0093] When the mounting ring 11 drives the guide wheel 72 away from the clamping mechanism 6 on this side, the guide wheel 72 separates from the inclined push plate 77, the connecting rod 75 resets along the limit rod 8 under the action of gravity, the vertical rack 74 drives the transmission gear 73 to rotate in the opposite direction, the crescent-shaped clamping block 63 resets and re-clamps the glutinous yam, ensuring the stability of the subsequent peeling process.

[0094] S6. Peeling complete and repositioning:

[0095] When the mounting ring 11 moves to the other end along the axis of the glutinous yam and the vision sensor detects that the entire surface of the glutinous yam has been peeled, the first motor 33, the second motor 53 and the vision sensor are turned off in sequence; the rotating rods 62 on both sides are driven to rotate in the opposite direction, so that the crescent-shaped clamping block 63 is completely released and the peeled glutinous yam is taken out; finally, the electromagnetic spring 41 and the torsion spring are controlled to reset, and the mounting ring 11 moves in the opposite direction along the lead screw 51 to the initial position, completing one peeling operation.

[0096] The functional principle of this invention can be explained through the following operational methods:

[0097] Positioning and clamping: The glutinous yam is coaxially fixed by the crescent-shaped clamping blocks 63 on both sides to prevent it from shifting or rotating during the peeling process;

[0098] Tension adaptation: A visual sensor detects the surface contour, and an electromagnetic spring and a torsion spring work together to adjust the initial tension of the cutting line;
