Description

Technical Field

[0001] This invention relates to the field of agricultural product processing, and more specifically, to a slicing device and method for agricultural fruits. Background Technology

[0002] Some agricultural products contain a large amount of coarse fiber, which is distributed throughout the pulp, making the overall texture relatively tough. When cutting, these coarse fibers, like thin ropes, are prone to breakage or stretching under stress, resulting in cracks or unevenness at the cut. This is similar to cutting a fibrous plant stem, where the continuity of the fibers is disrupted, causing it to split. Cracks after cutting affect the quality of the slices, or the sliced ​​fruits may be of inconsistent sizes, making it difficult to meet the requirements of uniform half-fruit size and intact cuts for subsequent grading, packaging, and deep processing. Summary of the Invention

[0003] This invention provides a slicing device and method for agricultural fruits, solving the technical problems in related technologies where fruit fibers cause cracking and inconsistent fruit sizes when the fruit is cut.

[0004] This invention provides a slicing device for agricultural fruits, comprising:

[0005] Rack components;

[0006] The feeding cylinder is fixed on the frame assembly;

[0007] The upper disc assembly is fixed in the upper part of the frame assembly and arranged horizontally. The upper disc assembly includes an upper disc body and a base. The base is located on the top of the feed cylinder and has an upper disc groove. The upper disc body is placed horizontally in the upper disc groove. A protective disc is provided on the outer edge of the upper disc groove. An elliptical through hole is passed through the upper disc body.

[0008] The feeding disc assembly includes a feeding disc body, which is located below the upper disc body. A disc ring is provided on the outer wall of the bottom end of the base, and the outer edge of the feeding disc body is slidably connected to the disc ring. A feeding hole is opened on the feeding disc body.

[0009] The hydraulic pressing tool assembly includes a lifting hydraulic cylinder, a pressure beam, and a tool holder and blade module. The lifting hydraulic cylinder is arranged vertically and coaxially aligned with the center of the upper disc assembly. The lower end of the piston rod of the lifting hydraulic cylinder is connected to the pressure beam. The tool holder and blade module are arranged in a circular or concentric array below the pressure beam.

[0010] The blade holder and blade module includes a blade holder and blades. Each blade corresponds to an elliptical through hole and is coaxial with the elliptical through holes of the upper disc assembly. The bottom end of the blade holder is provided with a wedge-shaped chamfered groove. The blades can be slidably installed in the blade holder. The outer walls on both sides of the blade are provided with outwardly opening bosses. A stainless steel compression spring is provided between the bosses and the blade to provide elastic force for the bosses to open outward. The blade holder and blade module also includes an ejection actuator for ejecting the blades relative to the blade holder. The ejection actuator is a preloaded spring.

[0011] Support seats are distributed in a ring on the inner side of the protective disc. In the first stage of the lifting hydraulic cylinder pressing down, the bottom end of the blade clamp first abuts against the support seat, forming a stable reaction force and completing the initial cutting and pressing in. In the second stage of the lifting hydraulic cylinder continuing to press down, the ejection actuator ejects the blade to complete the deep cut. At the same time, the outer edge of the top of the boss slides in the groove and is guided by the wedge to open outward, entering the slit to separate the two halves of the fruit.

[0012] The invention further includes a sweeping arm assembly, which includes a sweeping arm rotating shaft and a sweeping arm. The end of the sweeping arm is connected to the shaft end of the sweeping arm rotating shaft. The sweeping arm is on the same plane as the upper disc assembly. The sweeping arm rotating shaft is supported by a bearing seat. The bearing seat is connected to a sweeping arm drive motor and a motor base for placing the sweeping arm drive motor. The motor base is connected to the inner wall of the feed cylinder through a connecting frame.

[0013] Furthermore, in this invention, a toothed ring is provided on the outer wall of the feeding disc body; an indexing servo motor is provided on the outer wall of the feeding cylinder, the output shaft of the indexing servo motor is connected to the toothed gear, and the toothed gear meshes with the toothed ring; the toothed gear is driven by the indexing servo motor to drive the toothed ring and the feeding disc assembly to rotate intermittently, so that the feeding hole and the elliptical through hole are switched in the vertical direction, realizing the short-term connection and blockage between the feeding hole and the elliptical through hole.

[0014] Furthermore, in this invention, the side of the elliptical through hole near the feeding disc assembly has a chamfered structure. When the fruit is separated, the lower edge of the separated fruit will be guided to the chamfered structure of the elliptical through hole, which will cooperate with the outward opening action of the boss.

[0015] In this invention, the lifting hydraulic cylinder is further installed on the top beam directly above the upper disc assembly. The top beam has a portal frame structure, and both sides of the top beam are bolted to the base.

[0016] In this invention, the chamfered groove is a wedge-shaped groove, wider at the top and narrower at the bottom, for sliding engagement with the outer edge of the top of the boss.

[0017] In this invention, the blade is further guided linearly within the blade holder by a guide slide and a limiting pin, and the blade is ejected from the blade holder by the ejection actuator.

[0018] Furthermore, in this invention, the knife clamp and the pressure beam are finely adjusted and quickly replaced by a dovetail slide and a clamping screw; a replaceable elliptical hole bushing is provided on the upper disc body, the replaceable elliptical hole bushing covering the inner edge area of ​​each elliptical through hole.

[0019] Furthermore, the present invention also includes:

[0020] The input conveyor belt is located on one side of the frame assembly and docks with the base;

[0021] A guide seat is located between the seat body and the end of the input conveyor belt;

[0022] An electrically controlled baffle is located at the end of the guide seat;

[0023] A photoelectric sensor is located on the outer wall of the guide seat and is electrically connected to the electronically controlled baffle to control the feeding cycle.

[0024] The material distribution plate is coaxially installed on the inner wall of the top of the feeding cylinder, and several inclined baffles are distributed in a ring on the inner wall of the material distribution plate.

[0025] The output conveyor belt is horizontally positioned at the bottom of the feed cylinder.

[0026] This invention also provides a method for slicing agricultural products and fruits, which uses the aforementioned slicing device for agricultural products and fruits to achieve slicing, including the following steps:

[0027] Feeding and insertion: Start the input conveyor belt to evenly deliver the fruit in the hopper to the outer edge of the seat; the electronically controlled baffle, in conjunction with the guide seat and photoelectric sensor, releases the material in a rhythmic manner; the sweeping arm assembly pushes slowly along the tangential direction, and the fruit enters the elliptical through hole of the upper disc assembly;

[0028] Indexing blocking: The indexing servo motor drives the toothed gear to keep the feeding disc assembly in a blocking state, ensuring that the fruit is supported;

[0029] First stage of downward pressure: The lifting hydraulic cylinder presses down, and the bottom end of the knife clamp first abuts against the inner support seat of the protective disc to form a stable reaction force, pressing into the fruit to form a shallow cut;

[0030] The second stage of downward pressure triggers the ejection mechanism, causing the blade to eject relative to the blade holder and penetrate the fruit along the short axis of the hole to form a long axis symmetrical cut; at the same time, the outer edge of the top of the boss slides in the groove of the inverted opening and is forced to open outward by the wedge guide, entering the cut to gently separate the two halves of the fruit.

[0031] Chamfered separation: The chamfered structure on the side of the elliptical through hole near the main body of the feeding disc guides the lower edge of the half fruit to move downward, which, in conjunction with the opening action of the boss, achieves complete separation of the fruit;

[0032] Indexing and feeding: After the lifting hydraulic cylinder returns to the safe height, the indexing servo motor rotates, and the feeding hole and the elliptical through hole are briefly coaxial. The two halves of the fruit fall into the feeding cylinder by gravity.

[0033] Feeding tray guidance and output: Half fruit is guided to the wall of the feeding cylinder by the inclined baffle of the feeding tray, slides along the wall to the bottom and enters the output conveyor belt, and is transported to the subsequent process.

[0034] The beneficial effects of this invention are as follows:

[0035] This invention employs the elliptical holes of the upper disc assembly and replaceable bushings for flexible pressing and geometric positioning, enabling the long axis of the fruit to automatically orient and receive stable support during indexing and blocking. Combined with the two-stage downward pressing of the lifting hydraulic cylinder, the first stage uses the blade clamp to generate reaction force with the support seat to complete pre-pressing and guide the opening, while the second stage uses the blade to push out along the short axis and penetrate in a pure shearing manner, inhibiting the stretching and pulling of coarse fibers from the source. At the same time, the boss passively opens under the wedge-shaped guide of the chamfered groove, and immediately and gently pushes apart after cutting. The half-fruit is then guided to fall by the chamfered opening and the short window indexing alignment, avoiding pulling and secondary damage throughout the entire process.

[0036] Through the coordinated operation of the above-mentioned components, the fruit cuts are made smooth and consistent, cracks are significantly reduced, half-fruit size is uniform, slice quality and yield are improved, and the adaptability of subsequent processes and overall production capacity stability are enhanced.

It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0048] This device is used for long-axis slitting, half-fruit separation, and smooth feeding of fresh fruit. The device is constructed around the process flow of "bearing positioning, feeding, slitting, separation, feeding, and conveying and collecting".

[0049] Specifically, such as Figures 1-9 As shown, a slicing device for agricultural products includes a frame assembly 100, an upper disc assembly 400, a sweeping arm assembly, a hydraulic pressing cutter assembly 900, a feeding disc assembly 500, a distributing disc assembly, a feeding cylinder 200, an input conveyor belt 810, and an output conveyor belt 820.

[0050] The upper disc assembly 400 is fixed to the upper part of the frame assembly 100 and arranged horizontally; the hydraulic pressing cutter assembly 900 is located above the upper disc assembly 400 and installed vertically; the unloading disc assembly 500 is coaxially installed below the upper disc assembly 400; the sweeping arm assembly is arranged tangentially along the surface of the upper disc assembly 400; the material distribution disc assembly is coaxially installed on the inner side wall of the top of the unloading cylinder 200; the output conveying assembly is located below and aligned with the unloading disc assembly 500; the input conveying assembly is located on one side of the frame assembly 100 and docks with the base 300.

[0051] In one embodiment of the present invention, the specific structure is as follows:

[0052] The frame assembly 100 adopts a stainless steel square tube welded frame with adjustable anti-vibration feet at the bottom; the frame assembly 100 is the foundation of the whole machine and supports all components; the feed cylinder 200 and each mounting plate are fixed on the frame assembly 100 by bolts; the upper disc assembly 400, the feed disc assembly 500 and the indexing drive assembly of the feed disc body 510 are located above the feed cylinder 200 and are arranged coaxially.

[0053] The upper disc assembly 400 includes an upper disc body 410 and a base 300. The base 300 is located on the top of the feed cylinder 200 and has an upper disc groove. The upper disc body 410 is placed horizontally in the upper disc groove of the base 300. A protective disc 420 is provided on the outer edge of the upper disc groove. An elliptical through hole is provided on the upper disc body 410. The major axis of the elliptical through hole matches the major axis of the fruit, and the minor axis limits the fruit diameter. A replaceable elliptical hole bushing is provided on the upper disc body 410, which covers the inner edge area of ​​each elliptical through hole.

[0054] The replaceable elliptical hole bushing is inserted into the inner edge slot of the elliptical through hole of the upper disc body 410. The pressing surface is slightly lower than the upper surface of the upper disc body 410, and the whole thing can be removed for cleaning.

[0055] The sweeping arm assembly includes a sweeping arm rotating shaft and a sweeping arm 720. The end of the sweeping arm 720 is connected to the shaft end of the sweeping arm rotating shaft. The sweeping arm 720 is on the same plane as the upper disc assembly 400. The sweeping arm rotating shaft is supported by a bearing housing (upper bearing and lower bearing). The bearing housing is connected to a sweeping arm drive motor 710 and a motor base 520 for placing the sweeping arm drive motor 710. The motor base 520 is connected to the inner wall of the feed cylinder 200 through a connecting frame.

[0056] The feeding disc assembly 500 includes a feeding disc body 510, which is located below the upper disc body 410. A disc ring is provided on the outer wall of the bottom end of the base 300, and the outer edge of the feeding disc body 510 is slidably connected to the disc ring. The feeding disc body 510 has a feeding hole, which can be a round hole or an elliptical hole. When the feeding hole is a round hole, its diameter is increased by a gap based on the minor axis dimension of the elliptical through hole of the upper disc. When the feeding hole is an elliptical hole, its minor axis dimension is increased by a gap based on the minor axis dimension of the elliptical through hole of the upper disc. The gap value ranges from 0.5 to 1.5 mm to avoid interference and ensure smooth falling.

[0057] A toothed ring is provided on the outer wall of the feeding disc body 510; an indexing servo motor 530 is provided on the outer wall of the feeding cylinder 200, and the output shaft of the indexing servo motor 530 is connected to a toothed gear 540, which meshes with the toothed ring; the toothed gear 540 is driven by the indexing servo motor 530 to drive the toothed ring and the feeding disc assembly 500 to rotate intermittently, so that the feeding hole and the elliptical through hole are switched in the vertical direction, realizing the short-term connection and blockage between the feeding hole and the elliptical through hole; an encoder or proximity sensor is provided on the indexing output shaft for alignment confirmation; the gap between the upper disc assembly 400 and the feeding disc assembly is controlled at 1-3mm.

[0058] The hydraulic pressing tool assembly 900 includes a lifting hydraulic cylinder 910, which is installed on the top beam directly above the upper disc assembly 400. The top beam has a portal frame structure, and both sides of the top beam are bolted to the base 300. The lifting hydraulic cylinder 910 is vertically arranged and coaxially aligned with the center of the upper disc assembly 400. The lower end of the piston rod of the lifting hydraulic cylinder 910 is connected to the pressure beam, and the hydraulic cylinder flange is fixed to the mounting surface of the top beam by bolts. The piston rod and the pressure beam are connected by a ball joint or flange and are equipped with anti-loosening washers. The pressure beam is provided with a support structure along the axial direction, and guide pillars and linear bearing assemblies are provided on both sides of the pressure beam. The guide pillar seats are connected to the frame assembly 100 by bolts to ensure the parallelism and repeatability of the pressing. The tool holder and blade module 920 is arranged in a circular or concentric array below the pressure beam. The tool holder and blade module 920 includes blades 922 and tool holders 921, so that the blades 922 correspond to each elliptical through hole and are coaxial with each elliptical through hole of the upper disc assembly 400.

[0059] A chamfered groove 925 is provided at the bottom of the tool holder 921. The chamfered groove 925 is a wedge-shaped groove, wider at the top and narrower at the bottom, for sliding engagement with the outer edge of the top of the boss 923. The blade 922 is located in the guide slide of the inner cavity of the tool holder 921 and can slide up and down relative to the tool holder 921. The tool holder 921 and the pressure beam are finely adjusted and quickly changed through the dovetail slide and the clamping screw. The blade 922 is kept linearly guided by the guide slide and the limit pin.

[0060] The blade holder and blade module 920 also includes an ejection mechanism, which is a pre-tensioned spring disposed between the blade holder 921 and the blade 922, used to eject the blade 922 downward relative to the blade holder 921 to complete the deep cutting action.

[0061] The boss 923 and the chamfered groove 925 are linked and separated: Bosses 923 are provided on the outer walls of both sides of the blade 922. The bosses 923 can open outward. During the pressing process, the outer edge of the top of the boss 923 slides along the groove of the chamfered groove 925 and is passively opened outward by the wedge guide. The bosses 923 are fixed to the side wall of the blade 922 by countersunk screws. A stainless steel compression spring 924 is placed inside between the blade 922 and the boss 923 to provide the elastic force for the bosses 923 to open outward. The chamfered groove 925 is chamfered (1-2mm) to reduce friction and fruit damage.

[0062] The side of the elliptical through hole near the feeding disc assembly 500 has a chamfered structure. When the fruit is separated, the lower edge of the separated fruit will be guided to the chamfered structure of the elliptical through hole. Combined with the outward opening action of the boss 923, the separation of the fruit is better achieved.

[0063] A support base is distributed in a ring on the inner side of the protective disc 420. Its support surface is located at the same horizontal plane as the downward pressing path of the blade clamp 921 or slightly lower than the upper surface of the disc. In the first stage of the downward pressing of the lifting hydraulic cylinder 910, the bottom end of the blade clamp 921 first abuts against the support base, forming a stable reaction force and completing the initial cutting and pressing. The support surface of the support base is covered with a replaceable wear-resistant pad. In the second stage of the downward pressing of the lifting hydraulic cylinder 910, the pre-tightening spring pushes the blade 922 out relative to the blade clamp 921 to complete the deep cut. At the same time, the outer edge of the top of the boss 923 slides in the groove of the chamfered groove 925 and is forced to open outward by the wedge guide, entering the cutting slit to push the two halves of the fruit apart.

[0064] Two-stage stroke control: the stroke of the lifting hydraulic cylinder 910 is detected in stages by a position sensor / limit switch; the first stage arrival signal triggers the blade 922 to push out the actuator, and the cylinder automatically returns after the second stage arrival; adjustable mechanical limits are set on both sides of the pressure beam to prevent overcutting, and a guide groove is provided between the inner walls of the protective disc 420, with the end of the pressure beam slidingly connected to the groove of the guide groove.

[0065] The fruit is pushed into the elliptical through hole by the sweeping arm 720. The replaceable elliptical hole bushing provides micro-pressure and damping. The long axis of the fruit automatically aligns with the long axis of the hole and is stably positioned. Two-stage downward cutting: the hydraulic cylinder drives the pressure beam to press down. The bottom end of the first stage blade holder 921 first abuts against the support seat in the protective disc 420, forming a stable reaction force and completing the initial cutting and pressing in. The second stage pre-tightening spring pushes the blade 922 out relative to the blade holder 921, penetrating the fruit along the short axis of the hole, forming a symmetrical cut along the long axis. The outer edge of the top of the boss 923 slides in the groove of the chamfered groove 925 and is forced to open outward by the wedge guide, entering the cut and gently separating the two halves of the fruit to prevent them from sticking together again. The feeding disc body 510 is driven to rotate, and in a short window, the feeding hole is aligned coaxially with the elliptical through hole. The support fails, and the two halves of the fruit fall into the feeding cylinder 200 under gravity.

[0066] The distributing disc assembly is coaxially mounted on the inner side wall of the top of the feeding cylinder 200. Several inclined guide baffles are distributed in a ring on the inner side wall of the distributing disc. The separated fruits are guided by the ends of the baffles to the cylinder wall of the feeding cylinder 200 and slide down the cylinder wall to the bottom of the feeding cylinder 200 for output.

[0067] An input conveyor belt 810 is provided at the input end, and a hopper is provided at the input end of the input conveyor belt 810. The fruit in the hopper is continuously fed into the slicing device through the input conveyor belt 810. A guide seat 610 is provided between the seat body 300 and the end of the input conveyor belt 810. A photoelectric sensor 620 is provided in the middle of the outer wall of the guide seat 610, and an electrically controlled baffle 630 is provided at the end of the guide seat 610. The electrically controlled baffle 630 and the photoelectric sensor 620 are electrically connected.

[0068] Above several holes in the upper disc assembly 400, through-beam or diffuse-reflection photoelectric sensors 620 are arranged to detect the entry and blockage of fruit, triggering the sweeping arm assembly to pause or alarm; if necessary, auxiliary detection points are set in the path of the sweeping arm 720.

[0069] A horizontally placed output conveyor belt 820 is provided at the bottom output end of the feeding cylinder 200. The output conveyor belt 820 is used to receive the separated fruit pieces and for subsequent processing.

[0070] It should be further explained that the major axis of the elliptical through-hole is slightly larger than the average fruit length by 2-4 mm; the minor axis is slightly smaller than the average fruit diameter by 0.5-1.5 mm, forming a limit to elastically clamp and limit the whole fruit before cutting. After cutting, when the boss 923 opens outward, it pushes the half fruit away. When the half fruit falls, it is guided by the chamfered structure at the lower edge of the elliptical through-hole and enters the larger-diameter feeding hole below, so it will not get stuck due to the minor axis limiting size; the blade 922 has a cutting edge thickness of 0.3-0.8 mm; the indexing phase error does not exceed ±1°. The repeatability of the two strokes of the lifting hydraulic cylinder 910 should not exceed ±0.2mm, and the recommended ejection stroke of the blade 922 is 2-6mm; the height of the boss 923 should be 0.8-2.0mm; the linear speed of the sweeping arm 720 should be based on the principle of single-fruit entry without accumulation (0.1-0.4m / s); the coaxiality of the upper disc assembly 400 and the unloading disc assembly should not exceed 0.2mm; the gap between the upper disc assembly 400 and the unloading disc assembly should be 1-3mm; the gap between the sweeping arm assembly and the disc surface of the upper disc assembly 400 should be 2-5mm.

[0071] Based on the slicing device described above, a method for slicing agricultural products and fruits is also proposed, comprising the following steps:

[0072] Feeding and insertion: Start the input conveyor belt 810 to evenly send the fruit in the hopper to the outer edge of the seat 300; the electric control baffle 630, together with the guide seat 610 and the photoelectric sensor 620, realizes the rhythmic feeding; the sweeping arm assembly pushes slowly along the tangential direction, and the fruit enters the elliptical through hole of the upper disc body 410. The bushing provides pressure and damping to realize automatic orientation.

[0073] Indexing blocking: The indexing servo motor 530 drives the toothed gear 540 to rotate, so that the feeding disc assembly 500 is in a blocking state before pressing down (the feeding hole and the elliptical through hole are misaligned), ensuring that the fruit is supported during the cutting stage.

[0074] First stage of pressing down (initial cut): The lifting hydraulic cylinder 910 presses down, and the bottom end of the blade clamp 921 first abuts against the support seat inside the protective disc 420, forming a stable reaction force and pressing into the fruit to form a shallow cut; the position sensor detects that the first stage is in place and feeds back to the programmable logic controller.

[0075] The second stage of pressing down (deep cutting and ejection): The programmable logic controller triggers the pre-tensioning spring to push the blade 922 out relative to the blade holder 921 and penetrate the fruit along the short axis of the hole to form a long axis symmetrical cut; at the same time, the outer edge of the top of the boss 923 slides in the groove of the inverted groove 925 and is forced to open outward by the wedge guide, entering the cut to gently separate the two halves of the fruit.

[0076] Chamfering guidance and separation enhancement: The elliptical through hole has a chamfered structure on the side near the feeding disc body 510. After separation, the lower edge of the half fruit moves down along the chamfered guide, which, together with the opening action of the boss 923, improves the thoroughness of separation.

[0077] Indexing and unloading: After the lifting hydraulic cylinder 910 returns to the safe height, the indexing servo motor 530 drives the unloading disc assembly 500 to rotate, making the unloading hole and the elliptical through hole coaxially aligned in a short window. The two halves of the fruit fall into the unloading cylinder 200 by gravity. The encoder confirms the alignment window to avoid misplacement.

[0078] Feeding tray guidance and output: The half fruit is guided along the inclined baffle of the feeding tray to the wall of the feeding cylinder 200, slides along the wall to the bottom and enters the output conveyor belt 820; the output conveyor belt 820 sends the half fruit to the subsequent process.

[0079] It should be noted that the abnormality and interlock are as follows: when any photoelectric sensor 620 detects a blockage or incomplete indexing, or when the hydraulic system is over-pressured or under-pressured, the programmable logic controller will trigger a shutdown or speed reduction, and the human-machine interface will display the fault point; automatic return and cleaning processes can be executed.

[0080] It should also be noted that shutdown and cleaning are also included: after shutdown, remove the protective cover, clean the upper disc bushing, the blade holder 921 and its chamfered groove 925, the blade 922, the feeding disc body 510 and the distribution disc channel; check the wear of the boss 923, the stainless steel compression spring 924, and the blade 922, and replace them if necessary; check the guide post and bearings and add food-grade lubricant.

[0081] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention, all of which are within the protection scope of the present invention.
