Description

Technical Field

[0001] This invention relates to the field of lotus root processing equipment technology, specifically to an integrated device for continuous processing of lotus roots in clear water that can establish a local contour reference based on the actual contour of adjacent lotus segments on both sides of the lotus root node during continuous conveying of clear water lotus roots, and control the opening of the cutting channel by using a dual-point synchronous neck probing action. Background Technology

[0002] Before lotus roots are peeled, sliced, pickled, quick-frozen, packaged, or processed into ready-to-eat dishes, they usually need to be cut along the nodes between adjacent segments. Whole lotus roots generally have issues such as bent axes, varying segment diameters, irregular cross-sections, localized surface depressions, and inconsistent node widths and neck depths. After washing, the surface of the lotus root is still covered with a water film, which can easily cause lateral shifting or axial movement during transportation, positioning, and cutting.

[0003] In the prior art, Chinese patent document CN114536422A proposes a pre-aligned and fitted positioning device for preventing excessive cutting of lotus root segments. This device uses a clamping system to hold the lotus root, a rotating system to rotate the lotus root, and a cutting system to position the segment at two points, ensuring the cutter fits snugly against the end of the segment. While this technology reduces the possibility of excessive cutting during manual segment removal, it shares similarities with traditional clamping and positioning methods: it requires clamping, rotating, and multiple sets of electrically driven mechanisms to change the position of the lotus root and the cutter. It does not establish a cross-segment local reference that varies with the overall diameter and axial height using adjacent segments on both sides of the segment, nor does it utilize two synchronous detection positions to distinguish between segment necking and individual surface pits. Furthermore, it lacks a mechanical constraint structure to directly prevent accidental cutting between the detection results and the cutter's descent path.

[0004] Therefore, this invention discloses an integrated device for continuous processing of lotus root, which is a contour-guided straightening and section-cutting device to meet the actual needs of continuous identification, stable pressing and controlled cutting of the neck section of lotus root when there are changes in the overall size, local posture and surface contour of the lotus root. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated contour-guided straightening and section-cutting device for continuous processing of lotus root in clear water, so as to solve the problems that existing devices, which use fixed blade positions, absolute height detection, or single-point contact positioning, are easily affected by changes in the overall thickness of the lotus root, axis rise and fall, and local small pits, and lack physical cutting constraints between the detection structure and the descent action of the cutter.

[0006] To achieve the above objectives, the present invention includes a conveying assembly with a cutting clearance opening on the frame, a vertically movable lifting guide above the cutting clearance opening, and a swingable contoured bridge installed below the lifting guide. Reference rollers at both ends of the contoured bridge contact adjacent lotus segments on both sides of the lotus root node, causing the bridge to rise, fall, and swing according to the actual diameter and axial posture of the lotus segments on both sides. A fork-shaped neck probe located between the two reference rollers detects the descent of the necked portion relative to the aforementioned local reference through two synchronous neck probe rollers.

[0007] The fork-shaped probe is slidably connected to the contoured cable tray via a probe rod. When the probe rod descends, it drives the linkage pin to move within the inclined linkage groove. The inclined section of the inclined linkage groove converts the vertical displacement of the probe rod into the lateral displacement of the quasi-cutting sliding door, causing the allowable hole to move between the cutter and the pass groove. Its vertical holding section allows the probe rod to continue descending at different necking depths, while keeping the quasi-cutting sliding door in an aligned state.

[0008] When the sliding door is in a position where no effective necking is detected, its solid plate is positioned horizontally between the cutter and the pass groove, and the permission hole is deviated from the cutter path. Only after both necking rollers have entered the necking section and the necking rod has reached the predetermined downward stroke, does the permission hole connect with the cutter and the pass groove. This establishes a mechanical correspondence between the "effective necking state" and the "cutter passable state".

[0009] A set of V-shaped support conveyor belts is installed on both sides of the cutting clearance opening. Each set consists of two belts extending along the conveying direction and inclined inward towards the conveying center. The two belts together support the lotus root and restrict its lateral rolling. A cutting clearance space is left between the two sets of support conveyor belts for the cutter to enter.

[0010] The beneficial effects of this invention are:

[0011] 1. By having the upstream and downstream reference rollers contact the adjacent segments on both sides of the lotus root node, and by making the contour bridge rise, fall and swing according to the overall thickness and local axis posture of the lotus root, the fork-shaped neck probe obtains the amount of descent of the neck section relative to the local reference formed by the two sides of the lotus root segment, which can reduce the possibility that the overall height change of the lotus root is mistaken for the neck section of the lotus root node.

[0012] 2. By rigidly connecting the upstream and downstream probe rollers to the same fork-shaped probe, the fork-shaped probe generates enough stroke to open the quasi-cut sliding door only when both positions spaced apart along the conveying direction have lowering space. Individual narrow recesses are usually still supported by another probe roller, thereby improving the filtering ability of irregular surface undulations.

[0013] 3. By using the probe rod, linkage pin and oblique linkage groove to drive the lateral movement of the quasi-cutting sliding door, the permission hole is only connected to the cutter and the pass-through groove when the probe is in an effective probe state. The position switch is used to interlock the conveying stop and the cutter descent, so that the joint recognition, cut holding, cutting channel opening and cutter action form a continuous correspondence, reducing the risk of the cutter falling accidentally and colliding with the quasi-cutting sliding door.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] like Figures 1 to 5 As shown, a contour-following, straightening, and segmenting integrated device for continuous processing of fresh lotus root is described. The direction in which the fresh lotus root moves from the feed guide trough 2 to the conveying component 3 is the conveying direction. The side of the lotus root that first enters the segmenting station is the upstream side, and the side that leaves the segmenting station is the downstream side. The direction perpendicular to the conveying direction in the horizontal plane is the transverse side.

[0025] The frame 1 is formed by connecting stainless steel profiles, and a continuous processing channel is formed on the upper part of the frame 1. The feed guide trough 2 is fixedly connected to the feed end of the frame 1. Its bottom wall gradually decreases from the inlet to the outlet, and its side walls gradually move closer from the inlet to the outlet, so as to guide the tilted lotus root to gradually adjust to extend along the conveying direction.

[0026] The conveying assembly 3 is located on the discharge side of the feed guide chute 2, and a cutting clearance opening 4 is formed between its upstream and downstream conveying sections. The width of the cutting clearance opening 4 along the conveying direction is greater than the thickness of the cutter 14, and it provides clearance allowance for the cutter 14 to undergo small-angle attitude changes with the contoured bridge 6.

[0027] The conveying assembly 3 has two sets of supporting conveyor belts 26, which are located on the upstream and downstream sides of the cutting clearance 4, respectively. Each set of supporting conveyor belts 26 has two belts with corresponding lengths and start and end positions. The two belts extend parallel to each other along the conveying direction, and their inner sides are lower than their outer sides, so that the two upper bearing surfaces form a V-shaped supporting space that is wider at the top and narrower at the bottom in cross-section.

[0028] The driving and driven ends of each supporting conveyor belt 26 are respectively mounted on support seats adapted to the lateral inclination angle of the belt body. The support seats are connected to the upper end face of the frame 1 through a base plate and fasteners. The bearing mounting surface of the support seat matches the inclination direction of the corresponding belt body, keeping the drive roller axis parallel and preventing the inclined belt body from being twisted due to the horizontal installation of the support seat. The two sets of supporting conveyor belts 26 have the same conveying speed, so that the lotus root is continuously conveyed before and after passing through the cutting avoidance opening 4.

[0029] The two sets of supporting conveyor belts 26 can be driven by the same drive motor through a synchronous transmission mechanism, or they can be driven by drive motors that are synchronously controlled by the same controller. When cutting, the two sets of supporting conveyor belts 26 are braked at the same time so that the lotus root bodies on both sides of the cutting clearance 4 remain relatively stationary.

[0030] The frame 1 is located above the cutting clearance 4 and has an upper crossbeam. The upper crossbeam is fixedly connected to a vertical guide rail, and the lifting guide seat 5 is slidably connected to the vertical guide rail via a guide rail slider. Two bridge frame compression springs 16 are symmetrically arranged about the conveying center. The upper end of the bridge frame compression spring 16 abuts against the upper crossbeam, and its lower end abuts against the lifting guide seat 5, thereby continuously pushing the lifting guide seat 5 to move towards the conveying assembly 3.

[0031] The lower part of the lifting guide 5 is rotatably connected to the contoured bridge 6 via a swing shaft 15. The swing shaft 15 extends laterally, allowing the contoured bridge 6 to swing at a small angle relative to the lifting guide 5, but without disengaging from the lifting guide 5 in the conveying direction.

[0032] The upstream end of the contoured bridge 6 is rotatably connected to the upstream reference roller 7, and the downstream end is rotatably connected to the downstream reference roller 8. The rotation axes of the two reference rollers extend laterally. When the overall diameter of the lotus root increases, the two reference rollers jointly push the contoured bridge 6 and the lifting guide 5 to move upward. When the overall diameter of the lotus root decreases, the bridge compression spring 16 pushes the lifting guide 5 to move downward. When the diameters of adjacent lotus root segments are different or the local axis is tilted, the contoured bridge 6 rotates around the swing axis 15, so that the upstream reference roller 7 and the downstream reference roller 8 respectively fit into the corresponding lotus root segments.

[0033] The two ends of the contoured cable tray 6 are respectively provided with symmetrical adjustment slots 27. The roller brackets of the two reference rollers are slidably installed in the corresponding symmetrical adjustment slots 27 and fixed by locking parts. During adjustment, the two roller brackets are brought close to or away from the cutting plane at the same distance to keep the cutting plane between the two reference contact positions.

[0034] The neck guide sleeve 17 is fixedly connected to the middle of the conformal cable tray 6. Therefore, the neck guide sleeve 17 remains fixed relative to the conformal cable tray 6 and moves up and down and swings with the conformal cable tray 6 as a whole. The neck rod 18 slides through the neck guide sleeve 17 in the vertical direction, and its lower end is fixedly connected to the fork-shaped neck member 9.

[0035] The probe spring 19 is coaxially arranged with the probe guide sleeve 17 and the probe rod 18. The upper end of the probe spring 19 abuts against the lower end face of the probe guide sleeve 17, and the lower end of the probe spring 19 abuts against the upper end face of the upper spring seat of the probe rod 18, thereby driving the probe rod 18 and the fork-shaped probe 9 to move downward. One side of the probe rod 18 forms an anti-rotation plane, and the inner wall of the probe guide sleeve 17 is provided with a guide part that slides in cooperation with the anti-rotation plane to restrict the rotation of the fork-shaped probe 9 around the vertical axis.

[0036] The fork-shaped probe 9 has an upstream fork and a downstream fork that are arranged in front and behind along the conveying direction. The upstream fork is rotatably connected to the upstream probe roller 20, and the downstream fork is rotatably connected to the downstream probe roller 21. The two probe rollers move up and down synchronously with the fork-shaped probe 9 as a whole. A vertical through groove 10 is formed between the two forks. The outline dimension of the through groove 10 is larger than the corresponding cross-sectional dimension of the cutter 14 so that the cutter 14 can pass through.

[0037] The center distance between the two probe rollers is less than the center distance between the two reference rollers. When there is only one pit with a small axial width on a normal lotus root segment, one of the probe rollers may descend partially, but the other probe roller is still supported by the lotus root surface, and the fork-shaped probe 9 cannot obtain a complete descent stroke; when the constricted area of ​​the lotus root segment is located below both probe rollers at the same time, both probe rollers descend together.

[0038] The center distance between the two probing rollers is determined based on the effective axial width of the necked area of ​​the lotus root section in the batch to be processed and the typical axial width of the isolated surface pit. This center distance is made smaller than the effective axial width of the target necked area and larger than the typical axial width of the isolated pit that needs to be filtered, so that the two probing rollers can enter the target necked area at the same time and are less likely to fall into a single local pit at the same time.

[0039] The middle of the contoured cable tray 6 is fixedly connected to a laterally extending sliding door guide rail, and the precision cutting sliding door 11 slides in conjunction with the sliding door guide rail via a slide groove. The precision cutting sliding door 11 is a partial plate-like component located between the cutter 14 and the through-slot 10, and the allowable hole 12 passes through the precision cutting sliding door 11.

[0040] A vertical linkage lug is fixedly connected to the side of the sliding door 11 near the probe rod 18, and an oblique linkage groove 22 is formed on the vertical linkage lug. The oblique linkage groove 22 includes an oblique sliding section and a vertical holding section that are connected end to end. The oblique sliding section gradually approaches the permit hole 12 from top to bottom in the horizontal direction, and the vertical holding section continues to extend downward from the lower end of the oblique sliding section.

[0041] In the initial state, the linkage pin 23 is located at the upper end of the inclined section, the permitting hole 12 is offset from the descent path of the cutter 14, and the solid part of the pre-cutting sliding door 11 is located between the cutter 14 and the pass groove 10. The linkage pin 23 is fixedly connected to the side wall of the probe rod 18 and passes laterally into the inclined linkage groove 22. When the probe rod 18 descends, the linkage pin 23 first moves along the inclined section, applying a lateral force to the pre-cutting sliding door 11 through the groove wall of the inclined section, causing the pre-cutting sliding door 11 to move along the sliding door guide rail; after the linkage pin 23 enters the vertical holding section, the probe rod 18 can continue to descend, while the pre-cutting sliding door 11 remains in the position where the permitting hole 12 is aligned with the cutter 14.

[0042] The cutting assembly 13 is installed in the middle of the contouring bridge 6. The cutter drive 24 can be a servo electric cylinder, an electric push rod, or a pneumatic cylinder. The output end of the cutter drive 24 is connected to the cutter 14. The contouring bridge 6 is also provided with a vertical blade guide rail to limit the rise and fall of the cutter 14 along the cutting plane. The lower end of the cutter 14 forms a downward-protruding cutting edge in the middle, so that the blade gradually cuts into the lotus root from the middle to both sides.

[0043] The positioning switch 25 is fixedly connected to the contour cable tray 6 and is located at the end point of the lateral movement of the pre-cutting sliding door 11. When the pre-cutting sliding door 11 reaches the alignment position, its end triggers the positioning switch 25, thereby stopping the conveying assembly 3 and allowing the cutter drive 24 to drive the cutter 14 to descend.

[0044] The controller is electrically connected to the drive motor of the conveying component 3, the position switch 25, and the cutter drive 24 respectively. After the position switch 25 is triggered, the controller first brakes the conveying component 3, and then activates the cutter drive 24 after confirming that the conveying has stopped. After the cutter 14 is reset, the controller releases the conveying brake.

[0045] During operation, the lotus root enters the V-shaped channel formed by two sets of supporting conveyor belts 26 through the feed guide chute 2. The upstream reference roller 7 and downstream reference roller 8 are respectively attached to the surface of the lotus root under the action of the bridge frame compression spring 16, and the contoured bridge frame 6 rises, falls, and swings with the overall contour of the lotus root. Two probing rollers are attached to the contour of the lotus root located between the two reference rollers under the action of the probing spring 19.

[0046] When the necked section of the lotus root reaches the cutting plane, the upstream reference roller 7 and the downstream reference roller 8 are respectively supported on the thicker sections of the lotus root on both sides of the necked section. The upstream necking roller 20 and the downstream necking roller 21 simultaneously enter the necked area, and the fork-shaped necking member 9 drives the necking rod 18 to descend relative to the contoured bridge 6. The linkage pin 23 moves along the inclined section of the inclined linkage groove 22 and pushes the pre-cutting sliding door 11 to move laterally until the permit hole 12, the cutter 14 and the through groove 10 are connected vertically.

[0047] After the sliding door 11 is in position, the positioning switch 25 is triggered, the supporting conveyor belt 26 stops, and the cutter drive unit 24 drives the cutter 14 to pass through the permission hole 12, the cutting groove 10 and the lotus root node in sequence, and then enter the cutting clearance opening 4. Two probing rollers press the lotus root on both sides of the cut on the upstream and downstream sides of the cutter 14 to reduce the upward curling or axial movement of the lotus root during the cutting process.

[0048] After cutting, the cutter drive 24 drives the cutter 14 to reset, and the conveying assembly 3 restarts. The subsequent thicker lotus root segment pushes the two probe rollers upward, and the probe rod 18 drives the linkage pin 23 to move in opposite directions along the vertical holding section and the oblique moving section. The pre-cutting sliding door 11 returns to the initial position where the permit hole 12 is offset from the cutter 14, and the device enters the identification cycle of the next lotus root segment.

[0049] In one feasible configuration, the center distance between the upstream reference roller 7 and the downstream reference roller 8 is 50 mm to 120 mm, the center distance between the upstream probe roller 20 and the downstream probe roller 21 is 8 mm to 30 mm, the required probe descent stroke of the linkage pin 23 through the inclined section is 3 mm to 15 mm, and the length of the vertical holding section is 5 mm to 20 mm. These dimensions are selected based on the width of the lotus root nodes, the depth of the neck contraction, and the diameter of the lotus root segments in the same batch.

[0050] The preload of the neck spring 19 is less than the preload of the bridge compression spring 16, which enables the two reference rollers to stably establish a local reference, and the fork-shaped neck piece 9 can descend independently under this local reference, avoiding the neck spring 19 from pushing the entire contoured bridge 6 upward in the opposite direction.

[0051] The above embodiments are used to illustrate the structure and working process of the present invention. The actual size and driving form can be determined according to the specifications of the lotus root to be processed, while maintaining the above-mentioned component matching relationship.
