Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable slicing, specifically to a fruit and vegetable slicing device. Background Technology

[0002] One common step in processing fruits and vegetables is slicing. Multi-stage slicing devices use automatic reciprocating or rotating blades to efficiently cut fruits and vegetables into uniform thin or thick slices according to different needs, which improves processing efficiency while ensuring the integrity and appearance of the ingredients.

[0003] While existing slicing equipment has relatively mature blade layout and adjustment systems, some issues remain regarding the positioning and constraint of fruits and vegetables. This is primarily because when dealing with spherical or similarly spherical fruits and vegetables, their surface shapes are often irregular and curved. These shape variations increase the difficulty of clamping, thus affecting slicing accuracy and stability. Furthermore, the curved shape makes it difficult to maintain effective clamping at all times. As the fruit and vegetable shrink towards the end of the cut, clamping failure often leads to slippage or displacement, resulting in unsatisfactory cut shapes, tilted slice angles, and uneven slice thickness. This not only affects the final product quality but also increases the operator's adjustment burden.

[0004] Existing technologies commonly constrain fruits and vegetables, including mechanical clamping, vacuum adsorption, and channel constraint, but these methods are still insufficient when dealing with complex curved surfaces. Utility Model Content

[0005] The purpose of this invention is to provide a fruit and vegetable slicing device that can effectively hold fruits and vegetables, keep their posture unchanged during the advance, and slice them evenly and with good shape retention.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A fruit and vegetable slicing device includes horizontally and symmetrically arranged constraint modules. Each constraint module includes a vertically arranged clamping pulley, a guide pulley, a tension pulley, and a clamping belt wound around its outer surface. The inner portion of the clamping belt rotates from the guide pulley to the clamping pulley. The distance between the two guide pulleys is greater than the distance between the clamping pulleys of different constraint modules. A first slot channel is provided above the clamping pulleys, and a first slider is slidably fitted within the first slot channel. The top of the clamping pulley is rotatably connected to the first slider. The first slider has a sliding stroke that allows the clamping pulleys of different constraint modules to move closer or further apart. A compression spring is installed between the first slider and the first slot channel, and the compression spring has an elastic force that brings the clamping pulleys of the two constraint modules closer together. A cutting module is provided at one end of the constraint module, and the cutting module includes a cutting blade positioned near the clamping pulley.

[0008] Below the constraint module is a conveying mechanism, which includes a horizontally rotating conveyor belt. The constraint module is symmetrically arranged with respect to the conveyor belt. The clamping pulley is located near the unloading end of the conveyor belt, and the cutter is located at the unloading end and close to the unloading end.

[0009] The clamping pulleys of the same constraint module are 1-3, and the first slot channel of the constraint module on the same side is linearly arranged along the conveying direction of the conveying mechanism.

[0010] The first slot channel includes a first upper slot and a first lower slot that are arranged vertically and extend in the same direction. The width of the first upper slot is greater than that of the first lower slot. The inner ends of the first upper slot and the first lower slot are flush, and the length of the first upper slot is greater than that of the first lower slot.

[0011] The first slider is slidably connected within the first lower slot, and a first mounting block is fixed above the first slider.

[0012] The first upper slot is provided with a first adjusting block and a first pull rod. The first pull rod is arranged in the same direction as the first upper slot. The inner end of the first pull rod is fixed to the first mounting block. The outer end of the first pull rod passes through and slides with the first adjusting block. The compression spring is sleeved on the first pull rod, and the two ends of the pull rod act on the first adjusting block and the first mounting block respectively.

[0013] The first adjusting block is slidably connected to the first upper slot. A first strip cover is fixed above the first upper slot. A first strip hole extending along its length is passed through the first strip cover. The first strip hole is centered relative to the first upper slot. Two first screws that extend vertically upward through the first strip hole are fixed on the top surface of the first adjusting block. A first nut is fitted on the upper part of the first screw. A first sliding hole that slides through the first adjusting block and is slidably engaged with the first connecting rod is passed through the first adjusting block.

[0014] The first upper slot and the first lower slot have a stepped structure due to their different widths. The bottom of the first upper slot has two side walls with first protrusions. The top of the first slider has a first wing extending outward. The first wing is located between the stepped structure and the first protrusion. The first adjusting block is located above the first protrusion.

[0015] A second groove channel is provided above the tensioning pulley, and a second slider is slidably fitted in the second groove channel. The top of the tensioning pulley is rotatably connected to the second slider. The second slider has a sliding stroke to adjust the position of the tensioning pulley. A tension spring is installed between the second slider and the second groove channel. The tension spring has an elastic force that increases the tensioning pulley's gripping belt tension.

[0016] The second slot channel includes a second upper slot and a second lower slot arranged vertically. The width of the second upper slot is greater than that of the second lower slot, and their inner ends are aligned. The second slider is slidably connected inside the second lower slot. A second mounting block is fixed above the second slider. A second adjusting block and a second pull rod are provided inside the second upper slot. The second pull rod is arranged in the same direction as the second upper slot. The inner end of the second pull rod is fixed to the second mounting block, and the outer end of the second pull rod passes through and slides into the second adjusting block. The second adjusting block is slidably connected to the second upper slot. A second strip-shaped cover is fixed above the second upper slot. A second strip-shaped hole passes through the second strip-shaped cover and is centered relative to the second upper slot. Two second screws are fixed on the top surface of the second adjusting block, extending vertically upward through the second strip-shaped hole. A second nut is fitted on the upper part of the second screw. The tension spring is a helical spring and is located between the second mounting block and the second adjusting block. The tension spring has an elastic force that pulls the second mounting block toward the second adjusting block.

[0017] The constraint module also includes two transfer pulleys, which are arranged on both sides of the tension pulley. The clamping belt sequentially passes around the clamping pulley, guide pulley, transfer pulley, tension pulley, and transfer pulley to form a closed loop structure.

[0018] The constraint module also includes a plate disposed above the conveying mechanism, the first slot channel being fixed on the plate, and the top of the guide pulley being rotatably mounted to the plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This device is used for slicing fruits and vegetables. It can maintain a high degree of adaptability in the area near the cut while the fruits and vegetables are being pushed toward the cutter. The clamping band changes according to the curvature of the fruits and vegetables, and the fruit and vegetables are stably clamped as they are pushed toward the cutter, reducing slippage and deviation. As a result, the slices are of uniform thickness and have excellent quality and shape. Attached Figure Description

[0028] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0029] Example:

[0030] This example improves the positioning constraint part of the slicing device for fruits and vegetables, and its main structure includes:

[0031] The conveying mechanism adopts a common belt conveyor, which is a rotary conveyor belt 1 driven by a motor. The surface of the conveyor belt 1 is provided with anti-slip texture to ensure that the fruits and vegetables are stable and do not slip during the conveying process.

[0032] A constraint mechanism is provided above the conveying mechanism. The constraint mechanism is located near the unloading end of the conveyor belt 1. The constraint mechanism includes two constraint modules that are symmetrically arranged on the left and right sides of the conveying mechanism. The constraint modules cooperate with each other and are improved based on the belt clamping. The main structure includes a clamping pulley 2, a guide pulley 16, a tensioning pulley 18, a transfer pulley 17, and a clamping belt 29. The clamping belt 29 is wound around the pulleys to obtain a rotary reciprocating structure.

[0033] For ease of description, the conveying direction is defined as the length direction, and the width direction of conveyor belt 1 is perpendicular to the conveying direction, which can be simply referred to as the width direction.

[0034] In this example, the clamping pulley 2 adopts a dual-set structure, comprising two independently configured sets of clamping pulleys 2. The two sets of clamping pulleys 2 are arranged side by side along the conveying direction of the conveying mechanism and are independent of each other. The clamping pulleys 2 are located near the unloading end of the conveyor belt 1.

[0035] Above the clamping pulley 2 is a long strip-shaped first groove channel 3, the length direction of the first groove channel 3 is consistent with the width direction of the conveying mechanism, and a first slider 4 is provided in the first groove channel 3, which slides along its length direction. The bottom of the first slider 4 is rotatably connected to the top of the axle of the clamping pulley 2 through a bearing.

[0036] In terms of specific structure, the first slot channel 3 includes an upper slot 5 and a lower slot 6 integrally formed. The width of the lower slot 6 is d, and the width of the upper slot 5 is D. d is less than D, so that the lower half of the first slot channel 3 is narrower than the upper half. The top side of the lower slot 6 and the upper slot 5 form a stepped structure. The lower slot 6 is a waist-shaped closed slot structure. The length of the upper slot 5 is longer than that of the lower slot 6. The inner ends of the upper slot 5 and the lower slot 6 near the center of the conveying mechanism are aligned. The outer end of the upper slot 5 protrudes from the outer end of the lower slot 6 and extends outward.

[0037] The first slider 4 is located within the first lower slot 6 and is adapted to the width d of the first lower slot 6. The top of the first slider 4 is provided with a first wing plate 7 adapted to the width D, so that the cross-section of the first slider 4 forms a T-shaped structure. The bottom of the first upper slot 5 is provided with a first protrusion 8 that cooperates with the first wing plate 7. The first protrusion 8 and the step structure work together to ensure that the first slider 4 slides stably within the first slot channel 3 and is not easily deviated. This drives the clamping pulley 2 below to remain in a vertical state and has the ability to adjust its position along the first slot channel 3. Based on the symmetrical arrangement of the constraint modules on both sides, the distance between the two opposing clamping pulleys can be changed by adjusting the relative position of the clamping pulleys along the width direction, thereby adapting to the shape and height of the fruits and vegetables at that position.

[0038] A first mounting block 9 extending upwards and located within a first upper slot 5 is fixed to the first slider 4. A first pull rod 30 is passed through the first mounting block 9 and fixed by a nut. The first pull rod 30 is centrally located within the first upper slot 5 and extends in the same direction as the first upper slot 5. The first pull rod 30 extends outwards along the width direction of the conveying mechanism. A compression spring 10, which is a helical spring, is sleeved on the first pull rod 30.

[0039] A first strip cover 11 is fixed above the first upper slot 5. The length direction of the first strip cover 11 is consistent with the length direction of the first upper slot 5. The first strip cover 11 is used to close the outer part of the first upper slot 5. A first strip hole 12 extending along its length direction is passed through the first strip cover 11. The first strip hole 12 is centered relative to the first upper slot 5. A first adjusting block 13 is provided in the first upper slot 5 and slides with it. The first adjusting block 13 is a rectangular block adapted to the width D of the first upper slot 5. A spring groove is provided on the inner end face of the first adjusting block 13. The outer end of the compression spring 10 is installed in the spring groove. The inner end of the holding spring abuts against the first mounting block 9 on the top of the first slider 4, so that the clamping pulley 2 has a clamping force that pushes it toward the center of the conveying mechanism. The first adjusting block 13 has a first sliding hole that slides through it and engages with the first pull rod 30. Two first screws 14 extending vertically upward are fixed on the top surface of the first adjusting block 13. A first nut 15 is fitted on the first screw 14. The first screw 14 passes through the first strip hole 12. The first adjusting block 13 is fixed on the first strip cover 11 by the first nut 15. By adjusting the position of the first adjusting block 13, the compression amount of the compression spring 10 is controlled, thereby adjusting the clamping force of the clamping pulley 2, ensuring that the fruits and vegetables are clamped reliably and stably without damage during the transportation process.

[0040] Based on the above structure, the two symmetrical sets of clamping pulleys 2 achieve clamping of the fruit and vegetable surface through relatively adjustable movement with clamping force. In this example, there are two independent clamping modules along the conveying direction, that is, two sets of clamping pulleys 2 with relative clamping force. Each pulley can self-adjust to adapt to the circumference of the fruit and vegetable, especially when encountering the head and tail of the fruit and vegetable, it can conform to the undulations of the circumference of the fruit and vegetable, and clamp the fruit and vegetable at two points along the length of the fruit and vegetable near the cutting position, ensuring that the fruit and vegetable are stable and do not shake during cutting, thus improving cutting accuracy. At the same time, the adjustable clamping force design effectively avoids damage to the surface of the fruit and vegetable, ensuring product quality.

[0041] Furthermore, the clamping belt 29 is wrapped around the clamping pulley 2, so the contact with fruits and vegetables is made through the clamping belt 29. The surface of the clamping belt 29 can be made of anti-slip texture or soft material to enhance friction and reduce wear on the surface of fruits and vegetables.

[0042] The guide pulley 16 is located at the end of the clamping pulley 2 away from the feeding end. The guide pulley 16 is positioned against the outer end of the first lower groove 6 in the width direction of the conveying mechanism. Thus, when the clamping belt 29 passes between the clamping pulley 2 and the guide pulley 16 in sequence, the clamping belts 29 on both sides form a flared structure (with one end of the clamping pulley 2 being narrow), thereby gathering and guiding the dispersed fruits and vegetables, so that the fruits and vegetables are clamped one by one by the clamping belts 29 between the clamping pulleys 2.

[0043] The tensioning pulley 18 is disposed between the clamping pulley 2 and the guide pulley 16 in the length direction, and is disposed outside the guide pulley 16 in the width direction. There are two transfer pulleys 17, which are respectively located between the clamping pulley 2 and the tensioning pulley 18, and between the tensioning pulley 18 and the guide pulley 16, to provide support and guidance for the winding of the clamping belt 29. Based on this, the clamping belt 29 sequentially passes around two clamping pulleys 2, guide pulley 16, transfer pulley 17, tension pulley 18, and transfer pulley 17 to form a closed-loop structure. A drive structure can be added to the guide pulley 16, for example, a stepper motor can be connected to the axle of the guide pulley 16 through transmission to drive the rotation of the entire clamping belt 29. The rotation direction is that the clamping belt 29 on the inner side rotates from the guide pulley 16 towards the clamping pulley 2, while the clamping belt 29 on the outer side rotates in the opposite direction, completing the pushing action in the same direction as the conveyor belt 1. When the fruits and vegetables come into contact with the clamping belt 29, it can assist in pushing them to the lower end, and the funnel shape guides the fruits and vegetables in the center.

[0044] Above the tensioning pulley 18 is a structure similar to but opposite in direction to the elastic structure above the clamping pulley 2, specifically:

[0045] A second groove channel 19 extending in the width direction is provided above the tension pulley 18. The second groove channel 19 includes a second upper groove and a second lower groove with their inner ends aligned and arranged vertically. The length of the second upper groove is greater than that of the second lower groove, so the outer end of the second upper groove protrudes from the outer end of the second lower groove. The width of the second upper groove is greater than that of the second lower groove.

[0046] A second slider 20 is slidably fitted inside the second lower slot. The bottom of the second slider 20 is rotatably connected to the top of the tension pulley 18 axle via a bearing. The top of the second slider 20 is provided with a second wing plate, the width of which is adapted to the width of the second upper slot. The two side walls at the bottom of the second upper slot are provided with second protrusions, the bottom surface of which engages with the top surface of the second wing plate to facilitate smooth sliding of the second wing plate within the slot, ensuring flexible adjustment of the tension pulley 18 and further optimizing the tension direction of the clamping belt 29. A second mounting block 21 located inside the second upper slot is fixed above the second slider 20. A second pull rod 22 extending outward along the width direction is fixed on the second mounting block 21. A tension spring 23 is sleeved on the outside of the second pull rod 22. The tension spring 23 has an elastic force that pulls the second pull rod 22 outward, thereby driving the tension pulley 18 outward and maintaining appropriate tension of the clamping belt 29.

[0047] A second strip-shaped cover 24 is fixed above the second upper slot. A second strip-shaped hole 25 is passed through the second upper slot along its width direction. A second adjusting block 26 is provided inside the second upper slot and slides with it. A second pull rod 22 passes through the second adjusting block 26 and slides with it. Two vertical second screws are fixed above the second adjusting block 26. The second screws pass through the second strip-shaped hole 25 and are fitted with second nuts. The second adjusting block 26 is fixed to the second strip-shaped cover 24 by the second nuts. The tension spring 23 is disposed between the second adjusting block 26 and the second mounting block 21.

[0048] Based on the above structure, the tensioning pulley 18 can be guided and tended to move outward by the outward pulling of the tension spring 23 and the sliding cooperation of the second slot channel 19. When the clamping pulley 2 passively changes position with the undulation of fruits and vegetables, the tensioning pulley 18 maintains continuous tension on the clamping belt 29.

[0049] In terms of specific installation structure, the constraint module also includes a plate 27 disposed above the conveying mechanism. The plate 27 is fixedly installed, and a housing can be installed on the outside of the plate 27, or an exposed structure can be adopted. A support frame is provided on the outside of the plate 27 to support and fix the plate 27. The support frame can be fixed to the frame of the conveying mechanism, or directly fixed to the ground or operating table. Since the support frame is a common structure and not limited to the installation form, it is not shown in the attached drawings, which is easier to show other components. The top ends of the guide pulley 16 and the transfer pulley 17 can be directly mounted on the plate 27 through bearing components. The first slot channel 3 and the second slot channel 19 are fixed on the plate 27, thereby realizing the stable connection and positioning of each component.

[0050] A rotary cutter 28 is provided at the unloading end of the conveying mechanism. The constraint modules on both sides of the rotary cutter 28 are centrally located. The rotary cutter 28 is close to the unloading end and a rotating shaft is connected to the center of the rotary cutter 28. A motor module is driven on the rotating shaft to realize high-speed rotation drive of the rotary cutter 28 and ensure cutting efficiency.

[0051] Not limited to this example, a vertical cutter with a reciprocating stroke can also be used to repeatedly slice the material. The stroke of the cutter is precisely controlled by a drive mechanism to ensure consistent thickness with each cut.

[0052] Through the structural improvements described above, the clamping belts 29 on both sides first guide the fruits and vegetables on the conveyor belt 1 to a central position. Then, two sets of clamping pulleys 2, positioned near the cutting blade and positioned front and rear, stably clamp the fruits and vegetables. Each set of clamping pulleys 2 independently adjusts its clamping position, keeping it aligned towards the center. This provides excellent adaptability and clamping effect to the surface curves of the fruits and vegetables, even in areas with significant shape variations. This ensures stable feeding of the fruits and vegetables during the cutting process, avoiding cutting deviations caused by unstable clamping. The slices are uniform in size and thickness, improving cutting accuracy and efficiency.
