Description

Technical Field

[0001] This invention relates to the field of lotus seed peeling technology, specifically to a high-efficiency synchronous peeling device. Background Technology

[0002] In the deep processing of lotus seeds, peel removal is one of the core pre-processing steps. The efficiency and integrity of peel removal directly affect the quality of the finished product and the production efficiency of subsequent processing. Currently, lotus seed peeling is mainly divided into two categories: dry friction peeling and wet hydraulic peeling. Existing wet peeling equipment often uses fixed water guns for rinsing during the friction peeling process. However, the water spraying mechanism is mostly installed at a fixed angle, which cannot be precisely coordinated with the lotus seed dropping, rolling, and discharge actions. In the initial stage of dropping, the water pressure cannot concentrate on impacting the weak points of the seed coat. In the later stage of peeling, there are dead corners in the rinsing, and the skin debris on the lotus seeds cannot be washed off in time, easily adhering to the surface of the kernel, resulting in a high seed coat residue rate. Some equipment using oscillating water guns requires additional drive motors and electronic control systems, which are costly and prone to signal delays. Timing deviations reduce the peeling effect and also cause water to splash randomly during discharge, wasting water resources. Summary of the Invention

[0003] The purpose of this invention is to provide a high-efficiency synchronous peeling device.

The two synchronous annular grooves are slidably connected to the synchronous swing assembly.

[0008] Preferably, the roller assembly includes a friction wheel, which is coaxially sleeved on the friction rod. The friction wheel has a friction groove in the middle, and the lotus seeds to be peeled are rolled between the friction groove and the discharge assembly.

[0009] Preferably, the synchronous swing assembly includes two fixed sleeves, which are symmetrically arranged on the frame. A rotatable rotating shaft sleeve is coaxially provided inside each fixed sleeve. A connecting rod is coaxially passed through each rotating shaft sleeve. One end of the connecting rod is connected to the water gun, and the other end is provided with a synchronizing element between it and the synchronous ring groove.

[0010] Preferably, the synchronizing element includes a swing plate, the top of which is fixedly connected to the connecting rod, and a synchronizing rod is fixedly connected to the bottom of the swing plate. The synchronizing rod is slidably disposed within the synchronizing ring groove.

[0011] Preferably, it further includes a material separating structure, which is disposed above the peeling structure; The material distribution structure includes a material distribution hopper, at least one discharge port is provided at the bottom of the material distribution hopper, and a feeding chute is provided below the discharge port.

[0014] The above-described technical solutions in the embodiments of the present invention have at least the following technical effects or advantages: (1) The present invention uses the synchronous ring groove on the end face of the discharge wheel as the power input. Through the synchronous rod and the swing plate, the discharge component can rotate once and the synchronous swing component can drive the two water guns to swing back and forth once. No additional drive and electrical control components are required. Through the phase design of the cam groove trajectory, the water gun can accurately realize the timing of the entire process of water gun impacting the lotus seeds at the moment of discharge, water gun gradually swinging outward during the rolling peeling process, water gun swinging to the limit and discharge groove synchronously in place when peeling is completed. The concentrated water pressure quickly breaks the seed coat binding layer in the early stage of discharge, the rolling process thoroughly washes without dead corners, and the synchronous stop of the impact in the discharge stage ensures the thoroughness of peeling and avoids water waste, improving the synchronization accuracy and reliability.

[0015] (2) The present invention uses the same feeding shaft to drive the material feeding and anti-bridging vibration. Intermittent high-frequency vibration is generated by the cooperation of gears and return springs. The vibration frequency is matched with the feeding speed. The faster the feeding, the stronger the vibration, which fundamentally solves the problem of lotus seed bridging and jamming.

[0016] (3) The present invention has a built-in discharge trough in the discharge wheel. With the water pressure thrust of the swing water gun and the weight of the lotus seeds, the peeled lotus seeds fall accurately into the discharge trough. As they rotate, they fall to the receiving plate below and slide into the lotus hopper. There is no bouncing or scattering throughout the process. The discharge rhythm and the feeding rhythm are precisely matched through the transmission ratio to form a continuous closed-loop operation, which can be directly connected to the subsequent deep processing process.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] refer to Figure 1-10 A high-efficiency synchronous peeling device includes a frame 1, which is welded from food-grade 304 stainless steel to provide rigid support for the entire machine. A drive motor 2 is fixedly installed on one side of the frame 1, and a peeling structure 3 is installed in the middle of the frame 1. The peeling structure 3 is connected to the output shaft of the drive motor 2 via a synchronous gear transmission set. A material distribution structure 4 is installed above the peeling structure 3 to evenly distribute the lotus seeds to be peeled to the various peeling stations below.

[0025] The peeling structure 3 includes three parallel drive shafts: a feed shaft 31, a rotating rod 32, and a friction rod 33. One end of each shaft is rotatably mounted on the side walls of the frame 1 via bearing seats. All three shafts are linked to the drive motor 2 via synchronous gear sets, and are synchronously driven to rotate by the drive motor 2. The distance between the axes of the rotating rod 32 and the friction rod 33 is adapted to the diameter of the lotus seeds to be peeled, ensuring that the lotus seeds are flexibly clamped and have sufficient positive pressure. The fixed frame 34 is vertically fixed to the frame 1 by bolts, located above the rotating rod 32. Multiple peeling units are symmetrically arranged between the feed shaft 31, rotating rod 32, friction rod 33, and fixed frame 34 along the axial direction of the drive shafts, allowing for simultaneous peeling of multiple lotus seeds. Each station has a completely identical structure and synchronized operation.

[0026] Preferably, each peeling unit corresponds to an independent peeling station. The peeling unit includes a feeding component 35, a discharging component 36, a roller assembly 37, and a synchronous oscillating component 38. The multiple components work together to complete the feeding, positioning, rolling peeling, and oscillating rinsing of a single lotus seed. The feeding component 35 is coaxially sleeved on the feeding shaft 31 and can rotate synchronously with the feeding shaft 31, thereby realizing the transfer and positioning of lotus seeds one by one. The discharging component 36 is coaxially sleeved on the rotating rod 32 and can rotate continuously with the rotating rod 32. The roller assembly 37 is coaxially sleeved on the friction rod 33 and can rotate synchronously with the friction rod 33. The discharging component 36 and the roller assembly 37 rotate in the same direction, and the lotus seeds to be peeled are held between them by rolling. The lotus seeds are rolled in place by the co-rotation of the two components, and the skin on the surface of the lotus seeds is broken by contact friction, thus achieving the peeling of the lotus seeds. The fixed frame 34 is equipped with a synchronous swing assembly 38. One end of the synchronous swing assembly 38 is equipped with two water guns 39, which are symmetrically arranged on both sides of the lotus seed. The water outlet direction of the two water guns 39 is towards the lotus seed to be peeled. The water inlet end of the water gun 39 is connected to an external clean water supply system through a flexible high-pressure water pipe. The nozzle of the water outlet end adopts an "eight"-shaped water outlet pattern. A single nozzle can cover a large surface area of ​​the lotus seed. It can swing back and forth with the synchronous swing assembly 38, scanning and rinsing back and forth along the lotus seed axis to thoroughly eliminate rinsing dead corners. The other end of the synchronous swing assembly 38 is connected to the discharge assembly 36 for transmission and can move synchronously with the discharge assembly 36. Each rotation of the synchronous swing assembly 38 drives the two water guns 39 to complete one reciprocating swing, so that the rinsing action and the rhythm of the lotus seed rolling and peeling are precisely mechanically synchronized.

[0027] Preferably, the feeding assembly 35 includes a circular feeding groove wheel 352, which is coaxially sleeved on the feeding shaft 31 and rotates synchronously with the feeding shaft 31. Its top is directly opposite the discharge port of the material distribution structure 4. The bottom of the feeding groove wheel 352 is surrounded by a feeding chute 351 with a gap. The feeding chute 351 is fixed to the top of the fixing frame 34 by a bracket. The bottom discharge port of the feeding chute 351 is directly opposite the clamping gap between the lower discharge wheel 361 and the friction wheel 371. The feeding chute 351 guides the lotus seeds in the feeding wheel 352, directing them into the clamping gap between the discharge wheel 361 and the friction wheel 371 for subsequent peeling. Multiple feeding grooves 353 are evenly arranged in a ring on the circumference of the feeding wheel 352. Each feeding groove 353 is an arc-shaped groove adapted to the shape of the dried fruit, accommodating only a single dried fruit at a time, ensuring quantitative transfer of each fruit. A release hook 354 is inserted into the feeding wheel 352 to assist in removing dried fruits stuck in the groove, preventing sticking and affecting the feeding rhythm. A roller assembly 37 is correspondingly located at the bottom of the feeding chute 351, and a discharge assembly 36 is correspondingly located at the discharge port, ensuring that the dried fruit accurately falls into the clamping gap between the roller assembly 37 and the discharge assembly 36 after being transferred by the feeding wheel 352, completing the single-fruit feeding and positioning.

[0028] To achieve precise transfer of each lotus seed and avoid jamming caused by multiple seeds stacking, the feed trough 353 is designed to be single-seed-fit. During operation, the feed trough wheel 352 rotates continuously with the feed shaft 31. When the feed trough 353 rotates to the top, it receives the single lotus seed falling from the distribution structure 4 and is carried to the bottom outlet by the rotation. Under the action of gravity, the lotus seed falls vertically into the peeling station between the two wheels below, achieving precise transfer of each lotus seed and avoiding jamming caused by multiple seeds stacking.

[0029] Preferably, the discharge assembly 36 includes a discharge wheel 361, which is coaxially connected to the rotating rod 32 via a flat key and rotates synchronously with the rotating rod 32. A limiting annular groove 362 is coaxially formed in the center of the circumferential surface of the discharge wheel 361. The limiting annular groove 362 has an arc-shaped cross-section, adapted to the outer contour of the lotus seed. The limiting annular groove 362 and the roller assembly 37 roll and clamp the lotus seed to be peeled, limiting the axial displacement of the lotus seed and preventing it from coming out from the side during the rolling peeling process. A discharge groove 363 is formed at the bottom of the limiting annular groove 362. The depth of the discharge groove 363 is greater than that of the limiting annular groove 362, and the width is slightly greater than the diameter of the lotus seed. After the lotus seed is peeled, when it rotates to the position of the discharge groove 363 with the discharge wheel 361, the lotus seed falls into the groove under the combined action of water pressure and gravity. As it rotates to the bottom, it detaches from the discharge wheel 361, completing the automatic discharge. Both the groove surface of the limiting ring groove 362 and the groove surface of the discharge groove 363 are glued and fixed with rubber 364. The rubber 364 can be made of food-grade ductile rubber, which has a high coefficient of friction and excellent elasticity. It can stably drive the lotus seeds to roll in place and also buffer the clamping pressure to prevent the lotus seeds from being damaged by pressure. A lotus seed receiving plate is inclinedly set below the discharge wheel 361. The high end of the receiving plate is located directly below the discharge groove 363, and the low end is connected to the lotus hopper on the side of the frame 1. After the lotus seeds fall from the discharge groove 363 to the receiving plate, they slide smoothly into the lotus hopper along the slope to complete the discharge and collection, preventing them from bouncing and scattering. Two synchronous ring grooves 365 are symmetrically opened on the end face of the discharge wheel 361. The two synchronous ring grooves 365 are slidably connected to the synchronous swing component 38, which can convert the rotational motion of the discharge wheel 361 into the reciprocating swing power of the synchronous swing component 38, so that the rinsing action and the rolling and discharge action of the lotus seeds are precisely mechanically synchronized.

[0030] Preferably, the discharge assembly 36 includes a discharge arc block 366, which surrounds the bottom of the discharge wheel 361 and leaves a gap between it and the wheel surface of the discharge wheel 361. This ensures the smooth rotation of the discharge wheel 361. At the same time, when the discharge trough 363 rotates to the bottom, it can support the lotus kernels in the discharge trough 363, preventing the lotus kernels from falling out of the discharge trough 363 under the action of gravity, thus guiding the discharge of lotus kernels. A discharge hopper can be connected to the side of the discharge arc block 366 away from the roller assembly 37, which can realize the centralized collection of the peeled lotus kernels. The receiving plate 367 can be an L-shaped plate. The bottom of the receiving plate 367 is fixedly connected to the side of the discharge arc block 366 near the roller assembly 37. It can be fixedly connected with bolts through the waist-shaped hole. The top of the receiving plate 367 is bent and extends to the bottom of the clamping gap between the discharge wheel 361 and the roller assembly 37. This can block the lotus kernels and prevent them from falling into the gap under the friction wheel 371, which would cause the lotus kernels to break or get stuck, thus ensuring a smooth and stable discharge process.

[0031] Preferably, the roller assembly 37 includes a friction wheel 371, which is made entirely of food-grade silicone and is coaxially connected to the friction rod 33 via a flat key, rotating synchronously with the friction rod 33. A friction groove 372 is formed in the center of the circumferential surface of the friction wheel 371. The friction groove 372 and the limiting ring groove 362 of the discharge wheel 361 are opposite each other, forming a peeling channel for the lotus seeds. The lotus seeds simultaneously and flexibly contact the groove surfaces of both ring grooves, being held in the middle. The surface of the silicone friction wheel 371 has moderate friction. Combined with the rubber discharge wheel 361, when the two wheels rotate in the same direction at the same linear speed, they drive the lotus seeds to rotate stably in place, ensuring that the entire circumference of the lotus seeds is evenly rubbed and rinsed, resulting in uniform removal of the seed coat.

[0032] Preferably, the synchronous swing assembly 38 includes two fixed sleeves 381, which are symmetrically fixedly mounted on the fixed frame 34. Each fixed sleeve 381 has a coaxially mounted rotating shaft sleeve 382, ​​and a connecting rod 383 passes coaxially through the rotating shaft sleeve 382. The connecting rod 383 is clearance-fitted with the rotating shaft sleeve 382, ​​and both ends of the connecting rod 383 are screwed with nuts and washers. The nuts are pressed against the two end faces of the rotating shaft sleeve 382 by the washers, preventing axial movement of the rotating shaft sleeve 382 within the fixed sleeve 381 and ensuring free rotation of the connecting rod 383 within the fixed sleeve 381. The end of the connecting rod 383 near the lotus seed can be fixedly connected to the water gun 39 via a clamp, and the outer end extends out of the fixed sleeve 381 and is fixedly connected to the synchronous component. When the connecting rod 383 reciprocates with the rotating shaft sleeve 382, ​​it can drive the water gun 39 to synchronously change the spray angle, achieving full axial surface coverage and rinsing of the lotus seed.

[0033] Preferably, the synchronizing component includes a swing plate 384, the top of which is fixedly connected to the outer end of the connecting rod 383 via a flat key, and a horizontally arranged synchronizing rod 385 is fixedly connected to the bottom of the swing plate 384. The end of the synchronizing rod 385 is slidably embedded in the synchronizing ring groove 365. When the discharge wheel 361 rotates, the preset cam trajectory of the synchronizing ring groove 365 drives the synchronizing rod 385 to perform periodic reciprocating motion, which in turn drives the connecting rod 383 and the water gun 39 to reciprocate synchronously through the swing plate 384. By matching the phase of the synchronizing ring groove 365 and the discharge groove 363, the oscillation rhythm of the water gun 39 can be precisely matched with the lotus seed feeding, rolling peeling, and discharge processes. The pure mechanical linkage has no electrical control delay or error, effectively improving the stability of equipment operation and the consistency of peeling effect.

[0034] As the feeding wheel delivers the lotus seed to the gap between the two wheels, the discharge wheel 361 rotates to the dropping position. At this moment, the trajectory of the synchronous ring groove 365 is at its closest point, pushing the synchronous rod 385 to its innermost position. The swing plate 384 drives the water gun to swing to the center of the lotus seed, and two "eight"-shaped water jets concentrate on impacting the seed coat junction in the middle of the lotus seed, quickly breaking the seed coat adhesion. As the discharge wheel 361 continues to rotate, the trajectory of the synchronous ring groove 365 extends outward, pushing the synchronous rod 385 to gradually move outward, driving the swing plate 384 to move to the center of the lotus seed. As the water gun 39 swings outward, it gradually moves towards both ends of the lotus seed, coordinating with the lotus seed's rotation to thoroughly rinse the entire surface of the seed, promptly removing any seed coat debris. When the discharge wheel 361 rotates approximately one revolution and the lotus seed has completed full-circle peeling, the trajectory of the synchronous ring groove 365 reaches its farthest point, and the water gun 39 swings to the very end of the lotus seed's axis. At this moment, the discharge chute 363 rotates precisely to be directly beneath the lotus seed, and the seed falls into the discharge chute 363 under the combined action of the water pressure and gravity, completing a single-seed peeling cycle. Through the precise phase matching of the cam trajectory and the discharge chute 363, a purely mechanical structure can achieve strict synchronization of all processes, eliminating electrical control delays and errors, thus improving work stability and peeling consistency.

[0035] Preferably, the material distribution structure 4 includes a material distribution hopper 41, with multiple discharge ports 42 evenly arranged along the axial direction at the bottom of the material distribution hopper 41, each corresponding to the peeling unit below. A feed chute 351 is installed at each discharge port 42, and a vibration component 43 is installed between the side wall of the material distribution hopper 41 and the frame 1.

[0036] Preferably, the vibration assembly 43 includes two vertically formed vibration grooves 431 that extend through the distribution hopper 41. Each vibration groove 431 contains a vibration plate 432, one end of which is fixedly connected to the distribution hopper 41 and can vibrate slightly up and down within the vibration groove 431. A horizontal vibration rod 433 is fixedly connected to the bottom of both vibration plates 432, and both ends of the vibration rod 433 are mounted on the frame 1 via bearings. A vibration gear 434 is coaxially keyed to one end of the feed shaft 31, and a return spring 435 is fixedly positioned on the frame 1 at a corresponding location. The return spring 435 is arranged laterally, and a vibration toothed plate 436 is fixedly connected to its end, with the vibration toothed plate 436 meshing with the vibration gear 434. During operation, the feed shaft 31 drives the vibrating gear 434 to rotate. When the gear teeth disengage, they push the vibrating toothed plate 436 to rotate outward and compress the return spring 435. When the gear teeth of the vibrating gear 434 mesh with the vibrating toothed plate 436, the return spring 435 instantly rebounds, pushing the vibrating toothed plate 436 to rotate inward and reset. This cycle repeats, generating high-frequency intermittent impact vibrations on the vibrating toothed plate 436. The vibration is transmitted to the distribution hopper 41 through the vibrating rod 433 and the vibrating plate 432, causing the lotus seeds in the hopper to continuously loosen and flow downward, effectively preventing material bridging and jamming. Since the vibration power comes directly from the feed shaft 31, the vibration frequency is positively correlated with the feeding speed. The faster the feeding speed, the more times the gears engage and disengage per unit time, resulting in a higher vibration frequency. The anti-blocking effect of the distribution system automatically adapts to the production capacity without requiring additional adjustment.

[0037] The specific working principle is as follows: After the drive motor 2 starts, it drives the feed shaft 31, rotating rod 32 and friction rod 33 to rotate synchronously according to a preset transmission ratio through the gear set and sprocket mechanism; there is a speed difference between the rotating rod 32 and the friction rod 33, which causes the lotus seeds to generate relative friction.

[0038] After the peeled lotus seeds are poured into the distribution hopper 41, the vibrating gear 434 rotates continuously with the feed shaft 31, cooperating with the vibrating toothed plate 436 and the return spring 435 to generate high-frequency intermittent vibration, causing the distribution hopper 41 to shake slightly, so that the lotus seeds flow smoothly to each discharge port 42, avoiding accumulation and bridging, and ensuring a continuous and stable supply. The lotus seeds falling into the feed chute 351 enter the feed groove 353 of the feed wheel 352. The feed shaft 31 drives the feed wheel 352 to rotate at a uniform speed, transferring the single lotus seed from the top to the bottom discharge port, and accurately and vertically falling into the clamping gap between the limiting ring groove 362 of the discharge wheel 361 and the friction groove 372 of the friction wheel 371, completing the precise positioning of the single material. At this time, the synchronous ring groove 365 drives the water gun 39 to the center position, and the two figure-eight water jets concentrate on impacting the middle of the lotus seed.

[0039] The rotating rod 32 drives the discharge wheel 361 to rotate, and the friction rod 33 drives the friction wheel 371 to rotate in the same direction. The two wheels, through the flexible friction surfaces of the rubber and silicone, cause the lotus seed in the middle to rotate stably in place. The lotus seed coat continuously rubs against the surfaces of the two wheels, and the seed coat gradually loosens and falls off. Simultaneously, the synchronous annular groove 365 on the end face of the discharge wheel 361 pushes the synchronous rod 385 to move outward step by step with the rotation. Through the swing plate 384, the connecting rod 383 swings outward, which in turn drives the water guns 39 on both sides to swing outward step by step from the middle to both ends. The high-pressure figure-eight water jets scan and cover the entire surface of the lotus seed with the swing, promptly washing away the seed coat debris that has been ground off. At the same time, the seed coat is moistened to reduce frictional resistance and temperature, ensuring that the seed coat is thoroughly removed and preventing the lotus seed from overheating and breaking.

[0040] When the discharge wheel 361 rotates nearly one revolution, the entire seed coat of the lotus seed has been completely removed. At this point, the synchronous ring groove 365 reaches its farthest point, the water gun 39 swings to the axial end of the lotus seed, and simultaneously the discharge trough 363 rotates to be directly below the lotus seed. Under the combined action of the downward thrust of the water pressure at the end and its own gravity, the lotus seed detaches from the grip of the two wheels and falls into the discharge trough 363. The discharge wheel 361 continues to rotate, causing the lotus seed in the discharge trough 363 to rotate downwards. Guided by the top surface of the discharge arc block 366, the lotus seed slides smoothly into the discharge hopper, completing the entire peeling process for a single lotus seed. At the same time, the next lotus seed is fed into the peeling station through the feeding component 35, and the cycle repeats to achieve continuous peeling operation.
