Description

Technical Field

[0001] This invention relates to root and tuber crop processing technology, and in particular to an integrated processing device and method for yam shaping, peeling, and cutting. Background Technology

[0002] Yam is a common long cylindrical root vegetable widely used in food processing and medicinal herb preparation. The first step in processing yam is usually removing its skin and cutting it into sections. However, traditional yam peeling and cutting rely mainly on manual operation, which is not only inefficient but also prone to slipping due to the sticky sap on the skin and unstable handling. Furthermore, the yam sap contains irritating substances that can cause itching and discomfort upon skin contact. Secondly, manual peeling results in uneven peel thickness and slow speed, leading to fatigue over long periods and failing to meet the demands of batch processing. To address these shortcomings, existing technologies employ peeling devices for tuber crops, such as mechanical scrapers, brushes, or high-pressure steam peeling. However, most of these devices have simple structures and lack adaptability to the irregular shape of yams. The rigid, fixed blades cannot adhere to the skin when the yam diameter changes or the surface is uneven, often requiring the removal of an extra layer of flesh and resulting in material waste. Additionally, the slippery surface of peeled yams easily breaks and slips during transport, leading to low cutting efficiency. In addition, existing yam processing typically involves peeling and cutting into segments as two separate processes, requiring different equipment or manual labor. This not only occupies space and increases equipment costs but also introduces secondary pollution and labor intensity during transportation. Therefore, there is an urgent need for a device that can adapt to changes in yam diameter, reduce breakage and slippage during transport, and integrate peeling and cutting to improve the automation level and processing efficiency of yam primary processing.

The two end guide zones each occupy 20-30% of the effective width of the roller surface, and the surfaces are provided with guide patterns with an inclination angle of 35-60° facing each other. When the guide patterns roll, they generate a lateral component force pointing towards the middle friction-enhancing zone to drive the yam to be processed toward the centerline of the clamping and conveying channel.

[0024] The aforementioned yam shaping, peeling, and cutting integrated processing device further includes a spring seat for transmitting power to the clamping and conveying rubber roller, wherein the upper clamping and conveying component and the lower clamping and conveying component are connected to the upper clamping and conveying component and the lower clamping and conveying component. One end of the spring seat is connected to the bearing seat, and the other end of the spring seat is connected to the hollow roller shaft.

[0040] The tool holder is mounted on the tool shank; and

[0041] The cutting tools are mounted on the tool holder, and the cutting edges of the symmetrically mounted cutting components form a double-blade clamping cutting channel to complete the peeling of the yam to be processed.

[0042] The end of the tool holder away from the tool is provided with a stop block and a torsion spring to limit the micro-oscillation angle of the tool.

[0043] To better achieve the above objectives, the present invention also provides an integrated processing method for yam shaping, peeling, and cutting, wherein the integrated processing device for yam shaping, peeling, and cutting includes the following steps:

[0046] The contouring component of the contouring cutting mechanism macroscopically follows the outer diameter of the yam to be processed under the constant pressure of the contouring spring, and the cutting tool of the cutting component peels the skin of the yam to be processed by adhering to the skin of the yam to be processed; the torsion spring and the stop block perform micro-contouring of the skin of the yam to be processed to avoid scratches or missed cutting.

[0047] As the yam to be processed continuously passes through the clamping and conveying channel, multiple contour cutting mechanisms spirally arranged along the clamping and conveying channel sequentially peel the yam at various circumferential parts.

[0048] After peeling, the yams are fed to a cutting mechanism and cut into segments of a set length; and

[0121] The structural and working principles of the present invention will be described in detail below with reference to the accompanying drawings:

[0122] See Figures 1-3 , Figure 1 This is a schematic diagram of the device structure according to an embodiment of the present invention. Figure 2 for Figure 1 Front view, Figure 3 for Figure 1 The rear view of the yam contour peeling and cutting integrated processing device of the present invention includes: a frame 1, on which an inlet 11 and an outlet are provided, the inlet 11 and the outlet being coaxially arranged; a feeding conveying mechanism 2, corresponding to the inlet 11 and disposed at the front end of the frame 1, for supporting and centrally guiding the yam to be processed; a clamping conveying mechanism 3, corresponding to the inlet 11 and disposed on the frame 1, for applying an adjustable clamping force to the yam to be processed and uniformly advancing it along the length direction; the clamping conveying channel of the clamping conveying mechanism 3 and the center line of the feeding conveying channel of the feeding conveying mechanism 2 are located on the same straight line; A contour cutting mechanism 4, corresponding to the clamping and conveying mechanism 3, is mounted on the frame 1. The cutting edges of multiple contour cutting mechanisms 4 are arranged symmetrically in a spiral along the clamping and conveying channel of the clamping and conveying mechanism 3, and peel each part of the yam to be processed in sequence. During the peeling process, the outer diameter of the yam to be processed is macroscopically followed and microscopically contoured to avoid scratches or missed cuts. A cutting mechanism 5, corresponding to the discharge port, is located at the rear end of the frame 1 and is used to cut the peeled yam into segments of a set length. A power transmission mechanism 6 is mounted on the frame 1 and is connected to the clamping and conveying mechanism 3 and the cutting mechanism 5 respectively.

[0123] The power transmission mechanism 6 includes a drive motor 61, a main pulley 62, a driven pulley 63, a conveyor belt 64, a tension pulley 65, a tension adjustment component 66, and a drive gear 67. The main pulley 62 is mounted on the output shaft of the drive motor 61 and forms a transmission circuit with the conveyor belt 64. The tension and wrap angle are optimized through the tension adjustment component 66 and the tension pulley 65, driving each driven pulley 63 in sequence. The drive gear 67 is located on one side of the clamping and conveying mechanism 3 and is connected to the clamping and conveying rubber roller 311 through the driven gear 317, directly driving the clamping and conveying rubber roller 311 to rotate. The cylinder 33 is located adjacent to the clamping and conveying rubber roller 311 to provide clamping pressure. The drive motor 61 drives the main pulley 62 and the driven pulley 63 to rotate, thereby transmitting power to the drive gear 67, causing the clamping and conveying mechanism 3 to rotate to achieve the purpose of conveying yams. The air pressure of the cylinder 33 can be adjusted to allow the clamping and conveying mechanism 3 to clamp the yams, reducing the risk of yam breakage.

[0124] The drive motor 61 serves as the power source for the power transmission mechanism 6. Its output shaft engages with the main pulley 62 to provide continuous torque to the clamping / conveying side of the entire machine, providing stable linear speed and torque for components such as the clamping and conveying rollers 311, thus enabling conveying along the length direction. Located on the rear side of the frame 1 near the main pulley 62, it facilitates the formation of a compact belt drive circuit. The main pulley 62 is coaxial with the drive motor 61; the driven pulley 63 is mounted on the driven shaft, parallel to the main pulley 62; the entire power transmission mechanism 6 is located on the rear side of the frame 1. The conveyor belt 64 forms a closed loop around the main pulley 62 and the driven pulley 63, achieving flexible connection and transmission of the power from the drive motor 61, completing speed matching and torque amplification, and guiding the power to the gear stage and the clamping roller system. The tension adjustment component 66 and the tension pulley 65 constitute an adjustable tension / wrap angle control unit, located on the return section or slack side between the main pulley 62 and the driven pulley 63, ensuring spatial arrangement and belt wrap angle. The tension pulley 65 is connected to the frame 1 via an adjusting seat. The tension adjusting component 66 fine-tunes and locks its position. This maintains the appropriate tension and wrap angle of the conveyor belt 64, preventing slippage and stabilizing transmission efficiency and synchronization. The driven gear 317 is a cylindrical gear, installed on the drive shaft end of the clamping conveyor roller 311, located on the side of the clamping conveyor mechanism 3, on the same side as the belt drive output shaft. It meshes with the driving gear 67 on the belt drive output shaft, transmitting the power from the belt drive to the clamping roller system a second time to provide a constant-ratio rigid transmission, ensuring that the upper and lower clamping conveyor rollers 311 move at the same speed and are synchronized, thus stably conveying the yam.

[0125] In this embodiment, the drive motor 61, main pulley 62, conveyor belt 64, and driven pulley 63 constitute the first-stage belt drive structure, which drives the driven pulley 63 and subsequent gears after passing through the tensioning member. Two driven pulleys 63 of different sizes can be provided to cooperate with the same annular belt to complete multi-stage deceleration and distribution. The driving gear 67 on the driven shaft meshes with the driven gear 317 at the end of the clamping conveyor roller 311 to form a gear drive structure. The cylinder 33 is connected to the upper and lower clamping conveyor components 31 and 32 through the spherical bearing 34 to realize follow-up compensation and clamping adjustment.

[0126] The cutting blade of the cutting mechanism 5 is located at the outlet end of the clamping conveyor channel and aligned with the axis of the clamping conveyor channel; the discharge baffle 7 is located in front of the cutting zone for diversion and splash prevention. The cutting blade and its drive pair are fixed on the blade holder at the end of the frame 1 and are controlled by an independent drive source to achieve fixed-length cutting. The cutting blade can be a rotary type, a vertical reciprocating type, or a horizontal reciprocating type cutting structure.

[0127] The waste collection box 9 is located in the material drop area below the cutting channel and the clamping conveyor channel. A guide surface can be provided at the bottom of the frame 1 to facilitate the collection and fall of shavings. The limiting baffle 8 is located at the front of the clamping conveyor channel to prevent feeding jumps. The waste collection box 9 and the frame 1 can be connected by a drawer-type connection for easy removal and cleaning. The limiting baffle 8 is screwed to the side plate of the frame 1, and its position can be finely adjusted to adapt to different processing diameters.

[0128] See Figure 4 , Figure 4This is a schematic diagram of the feeding conveyor mechanism 2 according to an embodiment of the present invention. The feeding conveyor mechanism 2 in this embodiment is a V-shaped feeding structure, located at the feed inlet 11 at the front end of the frame 1 and aligned with its axial direction. Its discharge end is coaxially aligned with the inlet axis of the subsequent upper and lower clamping conveying components 31 and 32. The position is finely adjusted relative to the frame 1 using an adjusting rod 13, so that the discharge end is coaxial with the inlet of the upper and lower clamping conveying components 31 and 32. It includes: a bracket 21, located at the front end of the frame 1 corresponding to the feed inlet 11, and connected to the frame 1 via a support rod 12. An adjusting rod 13 is provided at the connection between the support rod 12 and the bracket 21. The adjusting rod 13 is used to finely adjust the position of the feeding conveyor mechanism 2 relative to the frame 1, so that the output end of the feeding conveyor mechanism 2 is coaxial with the inlet of the clamping conveying mechanism 3. The adjusting rod 13 is located between the feeding conveyor mechanism 2 and the frame 1, at the feed inlet 11. Nearby, the discharge center of the feeding conveyor 2 is precisely coaxial with the inlet center of the upper and lower clamping conveyor components 31 and 32. One end of the adjusting rod 13 is hinged to the bracket 21, and the other end is connected to the fixed surface of the frame 1. The position is finely adjusted by adjusting bolts, and locked after adjustment. This ensures that the feeding trajectory is aligned with the entire machine, adapting to yams of different diameters / curvatures and different cutter gap settings, reducing the risk of clamping impact and initial breakage, and improving centering and throughput. The driving wheel 24 is symmetrically installed at one end of the bracket 21; the driven wheel 25 is symmetrically installed at the other end of the bracket 21; the conveyor belt is tensioned on the driving wheel 24 and the driven wheel 25 respectively, forming the feeding conveying channel between the two conveyor belts, and forming a V-shaped angle to center and guide the yams to be processed; and the conveyor motor 23 is installed on the bracket 21 and connected to the driving wheel 24. The V-shaped conveyor belt is driven by an independent conveyor motor 23, which drives the V-shaped conveyor belt to complete the feeding process. The adjusting rod 13 is threaded to the frame 1 to achieve adjustability; the feeding end and the clamping conveying channel are connected by a transitional docking relationship without rigid connection.

[0129] The conveyor belt of the feeding conveyor mechanism 2 is tensioned on the V-shaped plate 22 and installed on the bracket 21, forming a V-shaped support and guide groove along the longitudinal direction. It works with the driving wheel 24 and the driven wheel 25 to form a closed transmission circuit. The driving wheel 24 and the driven wheel 25 are respectively installed on their corresponding wheel seats and fixed to the bracket 21 through their respective wheel seats, forming a support and tensioning path. This V-shaped feeding conveyor channel can provide self-centering support and anti-rolling guidance for long strip-shaped yams. It achieves a three-in-one support-guidance-conveyance during the feeding stage. The V-shaped working surface automatically centers the irregular cylindrical yams when they enter, stably feeding the yams into the clamping conveyor channel along the length direction, reducing clamping deviation and slippage.

[0130] The conveyor motor 23 serves as the power source for feeding, providing continuous and controllable feed power to match the cycle time of subsequent peeling and cutting. It is mounted on one side of the bracket 21 near the drive wheel 24 via a fixing plate, facilitating a shorter power circuit and increased wrap angle, thus integrating the output shaft and drive wheel 24 into a compact transmission system. The motor shaft and drive wheel 24 can be directly connected or connected via a coupling or belt drive, driving the conveyor belt to move continuously and form a stable linear speed for feeding, ensuring uniform feeding and creating a stable entry condition for subsequent clamping and contour cutting.

[0131] This embodiment also includes an adjustable support component consisting of a positioning rod 26 and an adjusting bolt 27, preferably using a groove + thread fine-tuning form, to achieve fine-tuning and locking of the feeding conveying mechanism 2 relative to the frame 1 in at least one degree of freedom of height / lateral or pitch angle.

[0132] See Figure 5 , Figure 5 This is a schematic diagram of the upper clamping and conveying component 31 according to an embodiment of the present invention. The clamping and conveying mechanism 3 of this embodiment includes an upper clamping and conveying component 31, a lower clamping and conveying component 32, and a cylinder 33. One end of the cylinder 33 is mounted on the frame 1, and the other end of the cylinder 33 is connected to the corresponding upper clamping and conveying component 31 and lower clamping and conveying component 32 respectively via a spherical bearing 34. The upper clamping and conveying component 31 and the lower clamping and conveying component 32 have the same structure. Taking the upper clamping and conveying component 31 as an example... Figure 5 As shown, the assembly includes: a bearing housing 314 mounted on the frame 1; a hollow roller shaft 312 connected to the bearing housing 314; a clamping conveyor roller 311 mounted on the hollow roller shaft 312; and a transmission component connected to the hollow roller shaft 312 and the power transmission mechanism 6, respectively. The upper clamping conveyor component 31 and the lower clamping conveyor component 32 are arranged vertically opposite each other, forming a through axial clamping conveyor channel; the discharge end is aligned with the cutting mechanism 5, and the inlet end is aligned with the feeding conveyor mechanism 2; the limiting baffle 8 is used to control the extreme positions of the upper and lower clamping conveyor rollers 311. The clamping conveyor roller 311 is mounted on the hollow roller shaft 312 and supported on the side plate of the frame 1 by the bearing housing 314; the spring seat 313 adjusts the clamping force in conjunction with the thrust of the cylinder 33; the one-way needle roller bearing 316 is used to realize the one-way self-locking function of the roller to prevent the yam from retreating. The upper and lower clamping conveying rollers 311 are driven at the same speed by the driven gears 317 to ensure stable conveying.

[0133] The hollow roller shaft 312 is a hollow roller shaft, which facilitates weight reduction and the arrangement of functional components such as the one-way needle roller bearing 316. Journals are machined at both ends to install bearings and end transmission components. It passes through the center of the clamping and conveying rubber roller 311, is perpendicular to the axis of the clamping and conveying channel, and extends beyond the bearing housing 314 at its end for mounting gears / couplings. It is fixed to the clamping and conveying rubber roller 311 and rotates as a whole. Both ends are supported by the bearing housing 314. The driven gear 317 at the end meshes with the output drive gear 67 of the power transmission mechanism 6 to achieve power input. As a torque-bearing and positioning component, it enables the coaxial rotation of the clamping and conveying rubber roller 311 and stably outputs the power transmitted by the belt / gear to the roller surface.

[0134] Bearing housing 314 is used to install and fix the bearings at both ends of the roller shaft, ensuring support and coaxiality. This ensures that the upper and lower clamping conveyor rollers 311 are parallel, coaxial, and have appropriate clearance, thereby obtaining a stable clamping bandwidth. The positioning holes / elongated holes on it can finely adjust the center height and parallelism. They are arranged in pairs on the left and right side plates or mounting beams of the frame 1, parallel to the axis of the clamping conveying channel. It can be connected to the frame 1 by bolts, supporting the end bearings of the hollow roller shaft 312; it can share the mounting base with the connecting plate 315 for assembly.

[0135] The connecting plate 315 is a plate-type connector, which may have positioning holes / elongated holes to connect the spring seat 313, bearing seat 314, or swing arm fulcrum, etc. It is located on the same straight line or in the same plane as the force chain containing the spring seat 313, facilitating force transmission. It can be screwed to the spring seat 313 and bearing seat 314; if necessary, it forms a triangular force-bearing structure with the hinge seat of the cylinder 33, improving rigidity and clamping accuracy. Structurally, it connects and mechanically transmits the resultant force of the cylinder 33 and the spring, causing it to act on the clamping conveyor roller 311, achieving adjustable and resettable clamping.

[0136] The clamping and conveying roller 311 is provided with a flexible coating made of food-grade flexible material, with a coating hardness of food-grade silicone Shore A 45–60. The roller surface of the clamping and conveying roller 311 is provided with a central friction-enhancing zone and two end guide zones along the axial direction. The width of the central friction-enhancing zone is 40–60% of the effective width of the roller surface, and its surface is provided with low-angle herringbone anti-slip patterns. The two end guide zones each occupy 20–30% of the effective width of the roller surface, and their surfaces are provided with guide patterns with an inclination angle of 35–60°. When these guide patterns roll, they generate a lateral force pointing towards the central friction-enhancing zone to drive the yam to be processed towards the center line of the channel. The depth of the central anti-slip groove is preferably 0.8–1.5 mm, and the depth of the two side guide grooves is preferably 0.6–1.2 mm; the thickness of the roller surface coating is preferably 3–6 mm.

[0137] The oblique / herringbone / spiral grooves in the guide zone decompose the contact friction force into an axial component (traction) + a radial / lateral component (pointing towards the center). If the yam deviates to one side, the lateral component generated by the oblique groove on that side pushes it back to the center belt, achieving automatic centering. The normal component of the grooves on both sides points inward, mirroring each other (herringbone), forming a "clamp-push-return to center" effect. When it approaches the center, the high-friction steady-state zone of the friction-enhancing grooves in the center belt provides higher longitudinal adhesion, locking its centered state and reducing further deviation. The perpendicular bisector of the plane containing the contact line (theoretical tangent) of the two clamping conveyor rollers 311 coincides with the axis of the clamping conveyor channel, which is the geometric center line of the channel. If the yam can stably remain within the center belt range (preferably ±2–5mm) after clamping without continuous deviation, it is considered to be centered.

[0138] The upper clamping and conveying component 31 and the lower clamping and conveying component 32 in this embodiment also include a one-way needle roller bearing 316, which is installed on the hollow roller shaft 312 or the transmission component to achieve one-way self-locking / overtravel and is installed in the same cavity as the bearing housing 314. The one-way needle roller bearing 316 is a needle roller clutch element used to achieve one-way self-locking / overtravel and is arranged between the roller shaft and the housing. It is installed in the bearing cavity at the end of the hollow roller shaft 312 or near the transmission end, and is installed in the same cavity as the bearing housing 314. The inner ring mates with the shaft and the outer ring mates with the housing. It can prevent backflow and loosening, and prevent the yam from driving the roller shaft to reverse in the event of a stop / impact condition, thereby improving the stability and safety of feeding.

[0139] The upper clamping and conveying component 31 and the lower clamping and conveying component 32 also include a spring seat 313, which is used to transmit external force to the clamping and conveying roller 311. It is arranged in the same direction as the force applied by the cylinder 33 and is hinged to the cylinder 33 via the spherical bearing 34 to cooperate with the cylinder 33 in providing constant pressure clamping and dynamic compensation. The spring seat 313 and the elastic element constitute a preload / floating unit for transmitting external force to the upper clamping and conveying roller 311. One end of the spring seat 313 is connected to the bearing seat 314, and the other end is connected to the hollow roller shaft 312. The cylinder 33 is hinged to the connecting plate 315 via the spherical bearing 34, superimposing adjustable clamping force to provide constant pressure clamping and dynamic compensation. This maintains a suitable clamping force when the yam diameter changes or the surface becomes slippery. Adjusted in conjunction with the cylinder 33, it prevents slippage and avoids over-clamping that could lead to breakage.

[0140] The cylinder 33 serves as a pressure regulating and opening / closing actuator. Its end is hinged to the connecting plate 315 of the clamping and conveying mechanism 3 via a spherical bearing 34. It is positioned on the same side as the force-bearing link of the clamping and conveying roller 311, facilitating direct force application. The cylinder 33 is fixed to the frame 1, and its piston rod is connected to the clamping and conveying mechanism 3 via the spherical bearing 34 to achieve clamping / releasing adjustment. The relationship between the cylinder 33 and the transmission chain is force-controlled—non-power transmission, providing adjustable clamping force and dynamic compensation to reduce the risk of yam breakage and slippage during conveying. It also works in conjunction with gear transmission to achieve stable feeding.

[0141] In this embodiment, the clamping and conveying roller 311 is pushed by the cylinder 33 and driven by gears to complete the clamping and conveying operations. The clamping and conveying roller 311 is made of soft material to reduce the breakage of the yam during clamping, and its surface has two types of anti-slip textures. The central anti-slip texture increases friction, while the side anti-slip textures cause the yam to move towards the center. The upper clamping and conveying component 31 and the lower clamping and conveying component 32 are arranged opposite each other, and their respective clamping and conveying rollers 311 are located on the upper and lower sides of the clamping and conveying channel, with their axes perpendicular to the clamping and conveying channel. The clamping and conveying roller 311 adopts a flexible rubber-coated roller body, and the roller surface is provided with two types of anti-slip textures. The central texture is deepened to increase friction and force transmission, while the side guide textures cause the yam to self-center towards the center, reducing the risk of clamping breakage and lateral slippage. The clamping conveyor roller 311 is keyed to the hollow roller shaft 312; the hollow roller shaft 312 is supported on the side plate of the frame 1 by the bearing seat 314, and is driven at the same speed by the end driven gear 317 meshing with the driving gear 67 of the power transmission mechanism 6 to clamp and push the yam. The flexible rubber layer, together with the friction-enhancing texture in the middle, provides stable traction, and the guide textures on both sides achieve centering self-guidance, significantly reducing slippage and breakage.

[0142] See Figure 6A , 6B and Figure 7 , Figure 6A This is a schematic diagram of the contour cutting mechanism 4 according to an embodiment of the present invention. Figure 6B This is a schematic diagram of the installation of another contour cutting mechanism 4 according to an embodiment of the present invention. Figure 7 This is a schematic diagram of the arrangement of the contour cutting mechanism 4 according to an embodiment of the present invention. The contour cutting mechanism 4 of this embodiment includes: a mounting frame 41, mounted on the frame 1 corresponding to the clamping and conveying channel; a rotating seat 42, mounted on the mounting frame 41, and adjusted at an angle relative to the mounting frame 41 corresponding to the clamping and conveying channel; a fixing block 43, mounted on the rotating seat 42; a contouring component 44, mounted on the fixing block 43; and a cutting component 45, symmetrically mounted at the lower end of the contouring component 44. The contour cutting mechanism 4 is arranged along the clamping and conveying channel, with its cutting edge 452 facing the center of the clamping and conveying channel and enveloping the outer contour of the yam. The overall contour cutting mechanism 4 uses the rotating seat 42 as its mounting base and is equiangularly distributed around the clamping and conveying channel at a regular hexagonal pitch (i.e., one position every 22.5°), achieving multi-angle gradual contact with the yam surface for peeling. Through elastic pre-tightening, the double blades form a tight, close-fitting cut on the yam within the clamping and conveying channel, and the cutting tool 452 automatically adjusts its position and posture according to the diameter and surface undulations.

[0143] The contouring component 44 in this embodiment is a four-bar contouring structure, including: a contouring mounting bracket 441; long contouring connecting rods 444, symmetrically arranged and with their lower ends connected to the contouring mounting bracket 441; short contouring connecting rods 443, symmetrically arranged and with their upper and lower ends connected to the fixing block 43 and the contouring mounting bracket 441 respectively; a compression connecting rod 442, which is a shear-type connecting rod structure with a central hinge, with both ends of the compression connecting rod 442 hinged to the top of the long contouring connecting rod 444, and contouring springs 445 are respectively provided between the connecting rods on both sides of the central hinge point of the compression connecting rod 442; a gravity balance connecting rod 446, connected to the long contouring connecting rod 444; and a gravity balance spring 447, with both ends connected to the fixing block 43 and the gravity balance connecting rod 446 respectively. The fixed block 43 serves as the base. The long and short contouring connecting rods 444 and 443, along with the compression connecting rod 442, are hinged to the tool holder 453 via a rotating shaft 454 through a sliding bearing 456. The end of the tool holder 453 supports the tool post 451 and the cutting tool 452. The contouring spring 445 provides constant pressure for macroscopic contour following, while the torsion spring 457 at the tool holder 453 provides rapid clearance for micro-contouring. The matching elastic coefficients of the two form a two-stage contouring system of macroscopic and microscopic contouring. The stop block 455 limits the extreme displacement of the cutting tool 452. The gravity balance connecting rod 446 and the gravity balance spring 447 counteract the weight of the contouring cutting mechanism 4, ensuring stable pressure.

[0144] To achieve one-time peeling of the yam, the cutting trajectory of the blade 452 covers the circumference of the yam. Around the central axis of the cutting channel, the mounting holes of the rotating base 42 are evenly distributed at 360° / 16 = 22.5°, forming a regular hexagonal phase arrangement. Each phase position can be equipped with a contour cutting mechanism 4, ensuring that the cutting edge points towards the center of the cutting channel. Using this regular hexagonal phase arrangement, only eight sets of double-blade clamping contour cutting mechanisms 4 are needed, arranged along the circumference. Figure 6A As shown, the double-blade clamping contour cutting mechanism 4 is a vertically arranged rotating seat 42 with a rotation angle of 0°, corresponding to... Figure 7 The position of ① in the middle; Figure 6B The diagram shows a double-blade clamping contour cutting mechanism 4, with a rotating base 42 arranged vertically on the right side at a rotation angle of 22.5°. Figure 7 Position ②; the double-blade clamping contour cutting mechanism 4 is a rotary seat 42 with a rotation angle of 45° on the right side, arranged vertically, corresponding to Figure 7 Position ③; the double-blade clamping contour cutting mechanism 4 is a horizontally arranged rotary seat 42 with a rotation angle of 22.5° on the left side, corresponding to... Figure 7 Position ④; the double-blade clamping contour cutting mechanism 4 is a rotating seat 42 with a rotation angle of 0°, arranged horizontally, corresponding to Figure 7 Position ⑤; the double-blade clamping contour cutting mechanism 4 is a horizontally arranged rotary seat 42 with a rotation angle of 22.5° on the right side, corresponding to... Figure 7Position ⑥; the double-blade clamping contour cutting mechanism 4 is a vertically arranged rotating seat 42 with a rotation angle of 22.5° on the left side, corresponding to... Figure 7 The position of ⑦; the double-blade clamping contour cutting mechanism 4 is a rotary seat 42 with a rotation angle of 45° on the left side, arranged vertically, corresponding to Figure 7 Position ⑧ in the middle. The equiangular arrangement of the regular hexagon allows the 16 phases to cover 360°. The circumferential double blades, in conjunction with the four-linkage and elastic elements, provide macroscopic and microscopic contouring, automatically cutting along the diameter and surface undulations without leaving any blind spots. The axial clamping and conveying mechanism 3 continuously advances at a constant speed, allowing the yam to pass through these equiangular phase blade groups in one go along its length. All circumferential parts are covered and cleaned when passing through the phase array.

[0145] See Figure 8A and Figure 8B , Figure 8A This is a schematic diagram of the cutting component 45 according to an embodiment of the present invention. Figure 8B for Figure 8A A cross-sectional view of AA. The cutting component 45 in this embodiment includes: a tool holder 453, which is hinged to the contour mounting bracket 441 via a pivot 454; a tool holder 451, which is mounted on the tool holder 453; and a cutting tool 452, which is mounted on the tool holder 451; the cutting edges of the cutting tools 452 of the symmetrically mounted cutting component 45 form a cutting channel to complete the peeling of the yam to be processed; a stop block 455 and a torsion spring 457 are provided at the end of the tool holder 453 away from the cutting tool 452 to cooperate in limiting the micro-oscillation angle of the cutting tool 452. The rotating shaft 454 serves as the center of micro-oscillation rotation, forming a rotating pair with the tool holder 451. A sliding bearing 456 is provided at the journal to reduce friction and improve return consistency. A torsion spring 457 is wound around the rotating shaft 454 to provide angular elasticity and preload. A stop block 455 cooperates with the relative limiting surface on the tool holder 453 or the tool holder 451 to limit the upper and lower limits of the micro-oscillation angle, preventing excessive clearance from causing missed cutting or tool edge jamming. The tool 452 is mounted on the front end of the tool holder 451, with the cutting edge facing the center of the clamping and conveying channel. The tool holder 451 and the rotating shaft 454 constitute a swing arm. The sliding bearing 456 is located between the rotating shaft 454 and the hole in the tool holder 451, and the material can be oil-impregnated bronze or food-grade engineering plastic bushing to ensure low friction at small angles.

[0146] In this embodiment, the double-blade clamping contour cutting mechanism 4 is arranged in pairs on both sides of the clamping and conveying channel, with the blades facing the center of the clamping and conveying channel, forming a double-blade clamping and close-fitting cutting action. A four-bar linkage mechanical contouring structure is used to automatically follow the outer diameter of the yam. The blade 452 is mounted at the end of the four-bar linkage mechanism. One end of the four-bar linkage is connected to a fixed block 43, and the other end supports the blade 452 and can swing radially relative to the yam. A contouring spring 445 is provided on the four-bar linkage mechanism to provide elastic pressure, ensuring that the blade 452 always presses against the yam surface with appropriate force. When the yam diameter changes, the yam surface pushes the blade 452, causing the four-bar linkage mechanism to open or close, allowing the blade 452 to automatically adjust its position according to the yam diameter, thus always closely adhering to the yam skin for uniform cutting. This four-bar linkage contouring structure can adapt to yams of different thicknesses and shapes, achieving contour-based peeling along the length direction. Regardless of whether a section of the yam is slightly thicker or thinner, it can effectively peel off the skin without excessively removing the edible internal parts.

[0147] The contouring component 44 is mounted on the rotary seat 42, and the entire component is equiangularly distributed around the channel with a regular hexagonal pitch. The rotary seat 42 has a position every 22.5°. A four-bar linkage structure plus a contouring spring 445 provides macroscopic contour following, while a torsion spring 457 at the end of the tool 452 provides rapid clearance for microscopic undulations, thus maintaining close contact with the cutting surface despite changes in diameter, ellipticity, or surface roughness. The rotary seat 42 is mounted on the mounting bracket 41 and serves as the support and positioning base for the contouring cutting mechanism 4. It is symmetrically arranged on both sides of the clamping and conveying channel, with its center pointing towards the axis of the clamping and conveying channel; the overall side view is as follows... Figure 7 The components are arranged in a ring shape. The rotating base 42 and the mounting bracket 41 are fixed to the frame 1. The rotating base 42 and each contouring component 44 are fastened to achieve 22.5° equal division positioning, so as to provide an equiangular mounting reference and form a regular hexagonal cutting array, which facilitates double-blade centering and multi-component collaborative cutting.

[0148] In this embodiment, the four-bar linkage contouring structure uses a fixed block 43 as a base. A compression link 442, a long contouring link 444, a short contouring link 443, and a rotating shaft 454 form a four-bar linkage. One end is hinged to the fixed block 43, and the other end supports the cutter 452 / knife holder 451. A contouring spring 445 provides constant pressure clamping force. The four-bar linkage is located between the cutter 452 and the rotating seat 42, with the linkage plane perpendicular to the yam's axial direction. The cutter 452 can swing radially relative to the yam. This allows for macroscopic contouring. When the yam's diameter changes, pushing the cutter 452 causes the linkage to open / close, automatically adjusting the position of the cutter 452 to ensure uniform peeling and reduce edible portion loss. The cutting tool 452 is mounted on the tool holder 451 and supported by the tool holder 453 and the rotating shaft 454. A torsion spring 457 and a stop block 455 are installed at the rotating shaft 454 to limit the micro-oscillation angle. A sliding bearing 456 is used at the key hinge point. The cutting tool 452 is located at the end of the four-bar linkage with its cutting edge facing the center of the clamping and conveying channel. The two cutting tools 452 are arranged opposite each other to form a clamping cutting zone. The tool holder 453 is hinged to the end of the four-bar linkage via the rotating shaft 454. The torsion spring 457 is mounted around the rotating shaft 454 and limited by the stop block 455. It works in parallel with the macroscopic contouring chain of the four-bar linkage to achieve microscopic contouring and impact protection. When encountering local protrusions / depressions, the torsion spring 457 quickly and elastically yields / returns to its original position to avoid scratches or missed cuts. It forms a macroscopic + microscopic two-stage follow-up with the contouring spring 445. The contouring spring 445 is a constant-pressure elastic element, and the gravity balance link 446 and the gravity balance spring 447 can counteract the weight of the mechanism. The contour spring 445 is connected in parallel between the connecting rods or between the mounting bracket 41; the gravity balance component is hinged to the connecting rod to provide constant pressure and anti-shaking, ensuring cutting stability and surface uniformity.

[0149] To address the issue of delayed response in the four-bar linkage mechanism when there are localized protrusions or depressions on the yam skin, this embodiment adds a torsion spring 457 micro-contouring structure to the mounting location of the cutter 452. The cutter 452 is hinged to the torsion spring 457, giving it a small degree of elastic rotational freedom relative to the end of the four-bar linkage. When the cutter 452 encounters a small protrusion or depression during scraping, the torsion spring 457 can compress rapidly, causing the cutter 452 to make a slight yielding or following motion to instantly adapt to the micro-undulations on the surface, achieving micro-contouring of the small undulations on the yam surface. In this dual-layer contouring structure, the elastic coefficient of the contouring spring 445 is smaller than that of the torsion spring 457. That is, the four-bar linkage is mainly responsible for following the macroscopic contour, while the torsion spring 457 is responsible for rapidly responding to changes in the microscopic contour. A torsion spring 457 is fixed between the end of the four-bar linkage and the cutter 452, allowing the cutter 452 a small degree of elastic rotational freedom relative to the end of the four-bar linkage. When encountering tiny protrusions / indentations on the yam surface, the cutter 452 can instantly yield or follow, completing micro-shaping. This, combined with the shaping spring 445, forms a two-stage shaping process. This two-stage elastic coordination ensures that the cutter 452 has both stable clamping force and sensitive buffering during processing. The four-bar linkage provides constant pressure to adhere tightly to the yam, preventing excessive softness from affecting the peeling depth. The torsion spring 457 provides additional flexibility, preventing scratches or missed areas due to sudden surface changes. This shaping structure significantly improves the adhesion and uniformity of peeling, allowing the yam skin to be completely removed with uniform peel thickness, reducing inedible skin residue and minimizing the loss of edible parts.

[0150] During operation, the yam to be processed is introduced through the V-shaped feeding conveyor 2 and enters the clamping and conveying channel formed by the upper and lower clamping and conveying components 31 and 32 from the feed inlet 11. After being peeled by the double-blade clamping and contour cutting mechanism 4 surrounding the channel, it continues to move forward to the cutting mechanism 5 located at the discharge port for segmentation. The peeling debris and residue generated fall into the waste collection box 9 below the frame 1. The discharge baffle 7 limits and guides the flow at the end. The whole process is an integrated linear process setting of "linear conveying - two-sided surrounding cutting - end cutting - bottom collection".

[0151] See Figure 9 , Figure 9 This is a schematic diagram illustrating the processing method according to an embodiment of the present invention. The integrated yam shaping, peeling, and cutting processing method of the present invention, used in the aforementioned integrated yam shaping, peeling, and cutting processing device, includes the following steps:

[0152] The yam to be processed is placed in the feed inlet 11, and is supported and centered by the V-shaped feed conveyor 2. The yam is stably conveyed to the inlet of the clamping conveyor 3.

[0153] The upper and lower clamping conveying rollers 311 of the clamping and conveying mechanism 3 rotate synchronously under the drive of the power transmission mechanism 6, apply an adjustable clamping force to the yam to be processed and advance it at a constant speed along the clamping and conveying channel in the length direction; the flexible coating, the middle friction-increasing zone and the guide zones at both ends of the clamping and conveying rollers 311 ensure the traction and self-centering of the yam to be processed.

[0154] The yam enters the cutting area of ​​the double-blade clamping contour cutting mechanism 4. Under the constant pressure of the contour spring 445, the contour component 44 of the contour cutting mechanism 4 macroscopically follows the outer diameter of the yam to be processed. The cutting tool 452 of the cutting component 45 adheres to the skin of the yam to be processed to peel it. The torsion spring 457 and the stop block 455 perform micro-contouring on the local small undulations of the skin of the yam to be processed, and quickly give way / return to avoid scratches or missed peeling, so as to improve the peeling uniformity and surface quality.

[0155] During the continuous single passage of the yam to be processed through the clamping and conveying channel, multiple contour cutting mechanisms 4, spirally arranged along the clamping and conveying channel, sequentially cover each circumferential part of the yam to be processed with an array of cutters 452 to complete the peeling. Each cutting component 45 is fixed to the rotating seat 42 and aligned axially with the clamping and conveying mechanism 3, so that the yam is sequentially shaved by each cutter 452 as it moves forward continuously. The superposition of macroscopic and microscopic contouring improves the fit and uniformity, avoids over-shaving or residual skin, and adapts to different thicknesses and irregular shapes. The double-blade clamping contour cutting mechanism 4 is arranged along a spiral line with a cross-section of a regular hexagon and rotates 22.5° through the rotating seat 42 to complete the peeling and cutting operation of the yam in one go.

[0156] After peeling, the yams are conveyed to the cutting mechanism 5 and cut into segments of a set length, thus completing the peeling and cutting processes in a single pass.

[0157] The segmented yam product and peels are discharged and collected separately through the discharge / collection device.

[0158] The yam contour peeling and cutting integrated processing device and method of the present invention solves the problems of uneven peeling, serious waste, conveyor breakage and slippage, and inability to coordinate operations in the prior art where peeling and manual cutting are performed separately or multiple machines are used for step-by-step processing. This device organically integrates cutting and peeling functions into one unit, completing both processes continuously with the same set of equipment, realizing a streamlined one-stop operation, avoiding intermediate handling and waiting, and achieving high efficiency and labor saving. It is preferably driven by a motor or other power source, which can automatically adapt to changes in the shape of the yam, efficiently completing the primary processing of the yam. During processing, the yam to be processed is fed into the clamping conveyor 3 by the feeding conveyor 2, and the power transmission mechanism 6 drives the clamping conveyor 3 to move the yam along its length. Correspondingly, the blades 452 on the double-blade clamping contour cutting mechanism 4 adhere to the yam surface for peeling, while the cutting mechanism 5 is located at the end of the peeling process, used to cut the yam into segments of a set length after peeling, realizing efficient contour peeling and automatic segmentation processing of yams. Compared with the prior art, the present invention has the following beneficial effects:

[0159] Automatic contour peeling is highly adaptable. It uses a four-bar linkage mechanism for diameter contouring, so that the blade 452 can automatically adjust according to the diameter of the yam, achieving uniform peeling of yams of different thicknesses in one go. Even if the yam is irregularly shaped, it can still peel it by following the surface, avoiding manual estimation of thickness and reducing unnecessary food waste.

[0160] With its rapid micro-contouring response and high-quality peeling, the blade 452 is equipped with a torsion spring 457 elastic element, which enables micro-contouring adjustment for small bumps and depressions. When there are local protrusions or depressions on the yam skin, the blade 452 can instantly move aside or follow, without scratching the protruding parts or missing the skin of the depressions, thus ensuring that the skin of the entire yam is removed cleanly and the surface is smooth and consistent.

[0161] The elastic matching structure is stable and precise. It incorporates the elastic difference between the contour spring 445 and the torsion spring 457, allowing macroscopic and microscopic contouring to perform their respective functions without interference. The four-bar linkage ensures that the cutter 452 maintains stable pressure on the yam, preventing frequent shaking due to minor fluctuations and ensuring smooth operation. The torsion spring 457 only activates when needed, providing additional flexibility. The combination of the two enhances the smoothness and accuracy of the peeling process, avoiding over-cutting and ensuring no residual skin remains.

[0162] It significantly improves processing efficiency, reduces manual labor and operational difficulty, lowers workers' exposure to yam mucus, and enhances the hygiene and safety of production. At the same time, the integrated equipment reduces land occupation and cost investment, and has significant practical value and promotion prospects in the field of yam primary processing.

[0163] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.

The tool holder is mounted on the tool shank; and The cutting tools are mounted on the tool holder, and the cutting edges of the symmetrically mounted cutting components form a double-blade clamping cutting channel to complete the peeling of the yam to be processed. The end of the tool holder away from the tool is provided with a stop block and a torsion spring to limit the micro-oscillation angle of the tool.

10. A method for integrated processing of yam by shaping, peeling, and cutting, characterized in that, The yam shaping, peeling, and cutting integrated processing device according to any one of claims 1-9 comprises the following steps: The yam to be processed is placed in the inlet, supported and centered by the V-shaped feeding conveyor mechanism, and transported to the inlet of the clamping conveyor mechanism; The clamping conveyor rollers of the clamping conveyor mechanism rotate synchronously, apply an adjustable clamping force to the yam to be processed, and advance it at a constant speed along the length direction of the clamping conveyor channel; the flexible coating, the middle friction-increasing zone, and the guide zones at both ends of the clamping conveyor rollers ensure the traction and self-centering of the yam to be processed. The contouring component of the contouring cutting mechanism macroscopically follows the outer diameter of the yam to be processed under the constant pressure of the contouring spring, and the cutting tool of the cutting component peels the skin of the yam to be processed by adhering to the skin of the yam to be processed; the torsion spring and the stop block perform micro-contouring of the skin of the yam to be processed to avoid scratches or missed cutting. As the yam to be processed continuously passes through the clamping and conveying channel, multiple contour cutting mechanisms spirally arranged along the clamping and conveying channel sequentially peel the yam at various circumferential parts. After peeling, the yam is conveyed to the cutting mechanism and cut into segments according to a set length. as well as The segmented yam product and peels were extracted and collected separately.
