Description

TECHNICAL FIELD

[0001] The present application relates to the field of food processing, in particular to an anti-crushing onion cube cutting mechanism and a continuous onion slicing device. BACKGROUND

[0002] In the field of food processing, onion slicing and dicing are common and important processes. Currently, onion cutting is mostly done using traditional blade cutting equipment, which generally works by rotating a cutter disc or reciprocating blades to cut the onion. However, on the one hand, the traditional cutting method can easily cause the onion to break due to extrusion during the cutting process, affecting the appearance quality and integrity of the finished product. On the other hand, the cutting size is not uniform, the efficiency is low, and it is difficult to achieve continuous production.

[0003] The currently disclosed Chinese patent with authorization publication number CN220030464U, a fruit and vegetable dicing machine with a dicing mechanism and a fruit and vegetable dicing machine, is used to set on the body of the dicing machine, including a dicing knife cylinder, which is arranged on the body in a manner that can rotate around its own axis, the dicing knife cylinder is a grid structure with dicing mesh holes distributed on the whole, a pressing roller is located outside the dicing knife cylinder and can be arranged on the body in a manner that can rotate around its own axis, the axial direction of the pressing roller is basically parallel to the axial direction of the dicing knife cylinder, and the pressing roller can extrude the sheet-shaped food material towards the inside of the dicing knife cylinder during rotation to form dicing-shaped food material inside the dicing knife cylinder, the dicing knife cylinder includes annular blades arranged in sequence along the axial direction and strip-shaped blades arranged in sequence along the circumferential direction of the dicing knife cylinder and extending along the axial direction of the dicing knife cylinder, each strip-shaped blade is arranged outside each annular blade to form a grid structure with dicing mesh holes.

[0004] According to the above-mentioned patent, the patent adopts a dicing method of rotating extrusion cooperation of the dicing knife cylinder and the pressing roller, so that the sheet-shaped food material after being cut by the slicing unit can continuously fall into the space between the dicing knife cylinder and the pressing roller, and the sheet-shaped food material can be extruded to form dicing-shaped food material in time when it falls into the space between the dicing knife cylinder and the pressing roller, without applying excessive force, and the sheet-shaped food material will not be damaged due to long-term extrusion, ensuring the overall dicing effect. However, the sheet-shaped food material is prone to stacking when it falls into the space between the dicing knife cylinder and the pressing roller, which can still cause the food material to be broken, affecting the dicing quality. Therefore, an anti-crushing onion cube cutting mechanism is needed to ensure that the sheet material enters the cutting area smoothly, avoid stacking, and improve the uniformity of dicing and the yield.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means and achieved specific purposes and functions of the present application, the present application is described in further detail below in combination with the drawings and specific embodiments.

[0036] Reference is made to Figures 1-6As shown, the anti-crushing onion cube cutting mechanism is arranged in the box 1 with the feeding area 11 and the discharging area 12, and includes the strip cutting cutter barrel 2 and the cube cutting cutter barrel 3 with the same cutting direction and the cutting plate body matched with the two, the cube cutting cutter barrel 3 is arranged below the side of the strip cutting cutter barrel 2, the cutting plate body is arranged obliquely on the side of the strip cutting cutter barrel 2 and the cube cutting cutter barrel 3 along the cutting direction, the cutting plate body is composed of the upper cutting plate 21 and the lower cutting plate 31, the upper cutting plate 21 and the strip cutting cutter barrel 2 are matched to form the strip cutting area, the lower cutting plate 31 and the cube cutting cutter barrel 3 are matched to form the cube cutting area, and the dispersion assembly arranged in the box 1 is further included, the dispersion assembly includes the first dispersion structure 4 for preventing the stacking of the onion slices before entering the strip cutting area and the second dispersion structure 5 for preventing the stacking of the onion strips before entering the cube cutting area, the first dispersion structure 4 is arranged on the upper cutting plate 21, the second dispersion structure 5 is arranged on the lower cutting plate 31, the first dispersion structure 4 has the first dispersion channel 41 arranged upstream of the strip cutting area, the second dispersion structure 5 has the second dispersion channel 51 arranged upstream of the cube cutting area, and the dispersion driver 6 for synchronously driving the actions of the first dispersion structure 4 and the second dispersion structure 5 is arranged between the first dispersion structure 4 and the second dispersion structure 5.

[0037] In the working state, the onion slices slide along the cutting plate body to sequentially pass through the strip cutting area and the cube cutting area, forming a step-by-step cutting path from the strip to the cube.

[0038] The strip cutting cutter barrel 2 is rotationally arranged on the box 1, and the surface of the strip cutting cutter barrel 2 is provided with a plurality of strip cutting blades arranged at equal intervals along the axial direction of the strip cutting cutter barrel 2, each of the strip cutting blades is a ring structure coaxial with the strip cutting cutter barrel 2.

[0039] The cube cutting cutter barrel 3 is rotationally arranged on the box 1, and the surface of the cube cutting cutter barrel 3 is uniformly provided with a plurality of cube cutting blades around the circumferential direction of the cube cutting cutter barrel 3, each of the cube cutting blades is a strip structure parallel to the axial direction of the cube cutting cutter barrel 3.

[0040] The driving source for driving the strip cutting cutter barrel 2 and the cube cutting cutter barrel 3 to rotate is not shown in the figure.

[0041] When the onion slices enter the cutting mechanism from the feeding area 11, they first slide along the first dispersion channel 41 of the first dispersion structure 4, separate the continuously falling onion slices one by one, prevent the occurrence of multi-layer stacking, and ensure that each onion slice can enter the subsequent process in a single-layer and uniform state.

[0042] Under the action of gravity, the onion slices continue to slide to the obliquely arranged upper cutting plate 21 and smoothly slide on the smooth surface of the upper cutting plate 21, and enter the cutting area formed by the rotating strip cutting cutter barrel 2 and the upper cutting plate 21. At this time, the strip cutting cutter barrel 2 rotates at high speed, and the longitudinal strip cutting blades on the outer periphery of the strip cutting cutter barrel 2 accurately cut the onion slices longitudinally into a plurality of elongated onion strips.

[0043] The finished onion strips slide off the end of the upper blade 21 into the secondary distribution channel 51 provided on the lower blade 31. The secondary distribution channel 51 also has an anti-piling function, which can further disperse the onion strips and keep them in a good distribution state, avoiding the impact on the subsequent dicing effect due to mutual entanglement or piling. At the same time, the dispersion driver 6 synchronously drives the primary dispersion structure 4 and the secondary dispersion structure 5, so that the flow rhythm of the two stages is consistent, ensuring stable overall operation.

[0044] Subsequently, the onion strips continue to slide along the lower blade 31 into the dicing area composed of the dicing cutter barrel 3 and the lower blade 31. In the dicing area, the high-speed rotating dicing cutter barrel 3 drives the transversely arranged dicing blades to act, performing rapid cutting processing on the onion strips. With the support of the lower blade 31, efficient shearing is achieved.

[0045] Finally, after two orderly cutting of longitudinal slitting and transverse dicing, the onion pieces are completely processed into uniform onion dices, which are smoothly discharged through the discharge area 12. During the whole process, the onion organization is dispersed before each cutting to prevent the onion organization from piling up, and the risk of crushing the onion organization during cutting is minimized.

[0046] Referring to Figures 2-8 As shown, the primary dispersion structure 4 includes a guide plate 42 and a conveyor belt 43, the conveyor belt 43 has a conveying surface that is horizontal to the guide plate 42, and the conveying surface and the guide plate 42 form the primary distribution channel 41. When the onion pieces pass through the primary distribution channel 41 into the slitting area, the onion pieces are arranged in a single layer and fed stably.

[0047] The guide plate 42 is arranged on the upper blade 21 along the inclined direction of the upper blade 21, and the conveyor belt 43 is arranged on the box body 1 along the surface direction of the guide plate 42.

[0048] The box body 1 is provided with a drive wheel set 431 for the conveyor belt 43.

[0049] Before the onion pieces enter the primary dispersion structure 4 from the feeding area 11, the onion pieces are placed on the conveyor belt 43, and the conveyor belt 43 is driven by the drive wheel set 431 to convey the onion pieces towards the guide plate 42 until they fall into the primary distribution channel 41. Under the restriction of the primary classification channel, i.e. the distance between the guide plate 42 and the conveying surface is only for the thickness of a single onion piece, so that the onion pieces are separated one by one, ensuring that each piece enters the slitting area in a single layer and in an orderly state.

[0050] Since the inclination angle of the guide plate 42 is consistent with the cutter plate body, it ensures that the onion slices can smoothly slide along the guide plate 42 to the cutting strip area on the lower cutter plate 31 after passing through the first distribution channel 41. The phenomenon of onion slices stacking before entering the cutting strip area is avoided, preventing the lower onion strips from being crushed due to excessive force, and providing a good cutting foundation for subsequent precise longitudinal cutting.

[0051] Referring to Figures 2-8 As shown, the guide plate 42 can vibrate on the upper cutter plate 21 along its inclination direction. When the guide plate 42 vibrates, the stacked onion slices are in a loose separation and disturbed state between the guide plate 42 and the conveying surface.

[0052] The upper end of the guide plate 42 has a guide rod 421 extending outward along its inclination direction, and the upper end of the upper cutter plate 21 is provided with a guide sleeve 422 for guiding the movement of the guide rod 421.

[0053] When the guide plate 42 starts to work, it vibrates on the upper cutter plate 21 along its inclination direction. The vibration effect is transmitted to the onion slices between the guide plate 42 and the conveying surface, making the stacked or closely contacted onion slices in a loose separation and disturbed state, further enhancing the dispersion effect.

[0054] At the same time, the guide rod 421 at the upper end of the guide plate 42 extends outward along its inclination direction and is nested in the guide sleeve 422, ensuring that the guide plate 42 always reciprocates along the set inclination path during vibration and does not deviate or dislocate. While vibrating stably, the onion slices are continuously separated dynamically, making the onion slices more uniform and smooth entering the cutting strip area.

[0055] Referring to Figures 2-8 As shown, the secondary dispersion structure 5 includes an upper baffle 52 and a lower baffle 53, and the lower baffle 53 and the lower cutter plate 31 form the secondary distribution channel 51, and the upper baffle 52 and the upper cutter plate 21 form a limiting channel 521 communicating with the secondary distribution channel 51. When the onion strips pass through the secondary distribution channel 51 and enter the dicing area, the onion strips are in a single-layer stable feeding state.

[0056] The upper baffle 52 is arranged on the box body 1 along the inclination direction of the upper cutter plate 21, and the lower baffle 53 is arranged on the box body 1 along the inclination direction of the lower cutter plate 31.

[0057] When the onion strips that have completed longitudinal cutting slide off the end of the upper cutter plate 21, they first enter the limiting channel 521 formed between the upper baffle 52 and the upper cutter plate 21. The flow direction of the onion strips is preliminarily guided and limited, so that they can enter the secondary distribution channel 51 below uniformly.

[0058] Subsequently, the onion strip continues to slide into the second distribution channel 51 formed between the lower baffle 53 and the lower knife plate 31, allowing only a single layer of onion strips to pass through in turn, providing a good cutting basis for subsequent accurate transverse cutting.

[0059] Referring to Figures 5-10 As shown, the surface of the lower knife plate 31 is evenly distributed with a plurality of guide strips 311 along the direction of the rotation axis 61 of the dicing cutter barrel 3, and a sliding path 312 parallel to the cutting direction of the dicing cutter barrel 3 is formed between every two adjacent guide strips 311 for the onion strip to enter one by one, and the edge of each guide strip 311 is a chamfered edge 3111 for guiding the onion strip to fall into the sliding path 312.

[0060] The two ends of the guide strip 311 extend to the two ends of the inclined direction of the lower knife plate 31, respectively.

[0061] When the onion strip slides out of the first distribution channel 41, it begins to move downward along the surface of the inclined upper knife plate 21 due to gravity. At this time, the onion strip contacts the lower knife plate 31 in a substantially vertical posture and gradually approaches the guide strips 311 evenly distributed along the direction of the rotation axis 61 of the dicing cutter barrel 3.

[0062] At the moment of contact with the guide strip 311, the chamfered edge 3111 of each guide strip 311 first makes gentle contact with one side of the onion strip, guiding and correcting the moving onion strip, smoothly introducing it into the corresponding sliding path 312, and avoiding deviation due to angle deviation. As the onion strip continues to slide, it maintains straight-line motion along the sliding path 312 between the guide strips 311, maintaining a stable posture and always consistent with the cutting direction of the dicing cutter barrel 3, ensuring that the blade can accurately act on the onion strip during subsequent cutting to achieve dicing.

[0063] Referring to Figures 5-10 As shown, the surface of the upper knife plate 21 is provided with a support strip 211 corresponding to each sliding path 312, which cooperates with the strip cutter barrel 2, and the surface of the support strip 211 is flush with the surface of the guide plate 42. When the onion pieces are cut on the plurality of support strips 211, the formed onion strips gradually slide into the corresponding sliding path 312 along the surface of the support strip 211.

[0064] The two ends of the support strip 211 extend to the lower end of the guide plate 42 and the lower end of the upper knife plate 21, respectively.

[0065] When the onion slices slide along the guide plate 42 into the cutting strip area, they first contact a plurality of support bars 211 on the surface of the upper cutter plate 21. The support bars 211 are arranged one by one at the position of each sliding path 312 and are flush with the surface of the guide plate 42, forming a continuous sliding support surface. The onion slices continue to slide downward under the action of gravity, pass through the surface of the support bars 211 in turn, and are cut into a plurality of elongated onion strips at this point in cooperation with the high-speed rotating cutting strip cutter cylinder 2.

[0066] After cutting, the formed onion strips continue to slide downward along the surface of the support bars 211 under the action of their own gravity and gradually enter the corresponding sliding path 312, preparing for subsequent dicing operations. In the entire process, the support bars 211 not only provide stable support for cutting, but also effectively guide the onion strips to accurately enter the designated sliding path 312, avoiding the occurrence of deviation.

[0067] Referring to Figures 2-4 , Figure 7 , Figure 10 and Figure 11 , the secondary dispersion structure 5 further includes a jet pipe 54, one of the jet pipes 54 is arranged at the upstream of each sliding path 312, and the jet pipe 54 can jet air along the surface of the lower cutter plate 31 in the sliding path 312. When the jet pipe 54 is working, the lowermost onion strip in the stacked onion strips is in a force state of accelerating into the secondary dispersion channel 51.

[0068] The jet pipe 54 is fixedly connected with the lower cutter plate 31.

[0069] When the onion strips slide from the primary dispersion channel 41 to the surface of the lower cutter plate 31, they enter the upstream area of each sliding path 312. At this time, the jet pipe 54 arranged at the upstream of each sliding path 312 starts to work and jets air outward along the surface of the lower cutter plate 31 in the direction of the sliding path 312.

[0070] The air flow acts on the stacked onion strips and exerts a forward thrust on the lowermost onion strip, causing it to accelerate and slide forward and smoothly enter the secondary dispersion channel 51 along the sliding path 312. The onion strips between the upper and lower layers are effectively separated, preventing the secondary dispersion channel 51 from being blocked due to stacking, and ensuring that the onion strips are stably conveyed to the dicing area in a single layer and continuous state.

[0071] Referring to Figures 2-4 , Figure 7 , Figure 10 and Figure 11As shown, the air jet pipe 54 has an air inlet 541 and a flat nozzle 542, and a plug 543 is inserted in the air jet pipe 54 and can move along the axis of the air jet pipe 54. When the plug 543 reciprocates in the air jet pipe 54, the air inlet 541 is periodically opened and closed, so that the nozzle intermittently sprays a pulse air flow.

[0072] The flat nozzle 542 is arranged close to the surface of the lower blade plate 31.

[0073] Compared with the continuous air jet mode, the pulse air flow can act on the onion strips at a higher instantaneous pressure, so that the onion strips can be separated more effectively, and the accumulation or misalignment caused by insufficient or uneven distribution of continuous air flow pressure can be avoided.

[0074] When the air jet pipe 54 starts to work, an external air source supplies air to the inside of the air jet pipe 54 through the air inlet 541, and the air is controlled by the plug 543 inserted in the air jet pipe 54. The plug 543 reciprocates in the air jet pipe 54 along the axis of the air jet pipe 54, periodically opens and closes the air inlet 541 during the movement, so that air can only enter the inside of the air jet pipe 54 at the moment when the air inlet 541 is opened, and is sprayed at high speed from the flat nozzle 542 close to the surface of the lower blade plate 31, forming an intermittent pulse air flow.

[0075] The pulse air flow acts on the onion strips upstream of the lower sliding path 312 along the surface of the lower blade plate 31, exerts an instantaneous impact force on the bottom layer of onion strips in the stacked state, promotes the onion strips to slide forward quickly and separate from the upper onion strips, and realizes the separation one by one. When the lower onion strips are sent away, the upper onion strips automatically fall on the lower blade plate 31, so that the onion strips enter the secondary distribution channel 51 in a stable and single-layer state, and the continuity and cutting quality of the cutting process are improved.

[0076] Referring to Figures 2-11 As shown, the upper sliding plate 22 is slidably arranged on the upper blade plate 21 and fixedly connected with the guide plate 42, the lower sliding plate 32 is slidably arranged on the lower blade plate 31 and fixedly connected with all the plugs 543, and the dispersion driver 6 is arranged between the upper sliding plate 22 and the lower sliding plate 32.

[0077] A rubber strip 221 is fixedly arranged between the upper sliding plate 22 and the upper blade plate 21.

[0078] A compression spring 321 is arranged between the lower sliding plate 32 and each air jet pipe 54.

[0079] The dispersion driver 6 has a rotating shaft 61 rotatably arranged on the box body 1 and a rotating part fixedly connected with the rotating shaft 61. The rotating part is located between the upper sliding plate 22 and the lower sliding plate 32, and is composed of a plurality of rotating rods 62 which are equally spaced along the axis of the rotating shaft 61. The two ends of each rotating rod 62 are in contact with the upper sliding plate 22 and the lower sliding plate 32, respectively.

[0080] The dispersion driver 6 rotates the rotating shaft 61 to drive the rotating rod 62 to rotate, and the rotating rod 62 pushes the upper slide plate 22 and the lower slide plate 32 at both ends to move synchronously and reversely, so that the guide plate 42 is vibrated continuously and synchronously, and the plug body 543 is periodically opened and closed to the inflation port 541.

[0081] Therefore, the onion slices are continuously vibrated and dispersed by the first dispersion structure 4 before entering the strip cutting area, so as to prevent stacking and blockage and ensure cutting of the onion slices one by one. Meanwhile, the onion strips are further dispersed by the second dispersion structure 5 before entering the dicing area, so as to avoid accumulation of the strip materials. The uniform dispersion and orderly conveying of the materials in the whole process from slicing to strip cutting and then to dicing are ensured, the cutting efficiency and the regularity of the finished product are improved, and the materials are prevented from being blocked and jammed.

[0082] When the rotating part rotates with the rotating shaft 61, the upper slide plate 22 is gradually pushed upward, and the lower slide plate 32 is gradually pushed downward, and at this time, the plug body 543 closes the inflation port 541.

[0083] When the rotating part extrudes the upper slide plate 22 and the lower slide plate 32, the rubber strip 221 is in a deformed state, and the compression spring 321 is in a compressed state.

[0084] When the rotating part rotates with the rotating shaft 61, the upper slide plate 22 is reset under the action of the rubber strip 221, and the lower slide plate 32 is reset under the action of the compression spring 321, and at this time, the plug body 543 opens the inflation port 541.

[0085] Specifically, when the dispersion driver 6 starts to work, the rotating shaft 61 drives the rotating part fixedly connected thereto to rotate synchronously. With the rotation of the rotating part, the upper slide plate 22 gradually moves upward under the pushing of the rotating part, and the lower slide plate 32 is extruded downward.

[0086] When the rotating part continues to rotate with the rotating shaft 61 and is separated from the upper slide plate 22 and the lower slide plate 32, the upper slide plate 22 quickly returns to the original position under the elastic force of the rubber strip 221, and the lower slide plate 32 is reset together under the release action of the compression spring 321. The guide plate 42 is vibrated by the continuous rotation of the rotating shaft 61, and the plug body 543 also realizes the periodic opening and closing of the inflation port 541, so as to effectively disperse the onion slices and onion strips.

[0087] Referring to Figure 2 The onion continuous slicing device comprises a centrifugal slicing mechanism arranged in the feeding area 11, and the anti-crushing type onion dicing cutting mechanism as described above.

[0088] The centrifugal slicing mechanism comprises a rotating cylinder and slots uniformly distributed around the circumferential direction of the rotating cylinder. A centrifugal supporting plate is arranged on the inner wall of the rotating cylinder corresponding to each slot. A slicing cutter is arranged on the outer wall of the rotating cylinder, and the rotating cylinder can rotate relative to the slicing cutter.

[0089] The centrifugal slicing mechanism is not shown in the figure.

[0090] When the onions are sent into the rotating cylinder of the centrifugal slicing mechanism, as the rotating cylinder rotates at high speed, the onions are thrown outward by the centrifugal force through the centrifugal support plate and move circumferentially close to the inner wall of the rotating cylinder. In this process, the part of the onion exposed to the notch is continuously cut by the slicing cutter, and the onion is cut off a layer of uniform thickness every time it passes through the slicing cutter.

[0091] When the cut onion slices are continuously thrown out and fall into the feeding area 11 of the box body 1, the onion slices are then sequentially subjected to the operations of slicing and dicing.

[0092] The present application effectively prevents the uneven stress phenomenon of onion slices and onion strips caused by stacking during the cutting process through the synergistic effect of the primary dispersion structure 4 and the secondary dispersion structure 5, and reduces the risk of crushing the onion tissue. The primary dispersion channel 41 cooperates with the vibration guide plate 42 to make the onion slices enter the slicing area in a single layer and orderly state, improving the dispersion effect. The secondary dispersion channel 51 performs secondary separation on the sliced onion strips to ensure that they enter the dicing area uniformly and stably.

[0093] Through the step-by-step guidance of the limiting channel 521 and the guide strip 311, the onion strips realize posture adjustment and path correction during the sliding process, ensuring that their movement direction is consistent with the cutting direction of the dicing cutter 3, greatly improving the cutting precision. At the same time, the support strip 211 provides a stable support surface for the slicing and guides the onion strips to accurately enter the sliding path 312, preventing misalignment. It ensures that the onion strips are stably conveyed to the dicing area in a single layer and continuous state, thereby realizing efficient and continuous cutting, producing onion dices of uniform size and high integrity, and improving the cutting quality and production efficiency.

[0094] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the protection scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
