A peeling component for peeling oranges

Abstract

The present invention discloses a peeling assembly for peeling oranges, belonging to the technical field of orange juice processing equipment. The peeling assembly includes a first connecting rod, a second connecting rod, a power mechanism, a cutting knife, a peeling knife and an elastic member. The first connecting rod and the second connecting rod are rotatably connected, and both ends of the elastic member are respectively connected to the two to constrain the angle of their opening and closing. The cutting knife and the peeling knife are fixedly installed at the end of the first connecting rod, and the power mechanism is fixedly connected to the free end of the second connecting rod. The output shaft of the power mechanism drives the second connecting rod through rotation, and then drives the first connecting rod and the cutting knife and the peeling knife to rotate. Since the peeling knife is located in the downstream section of the rotation track of the cutting knife, when peeling, the cutting knife first cuts a slit in the orange peel, and then the peeling knife attached to the orange pulp peels off the orange peel along the slit. The peeling assembly has a simple structure, low manufacturing cost, and is suitable for industrial production lines. Compared with the existing peeling type peeling device, the working efficiency can be greatly improved.

Description

Technical Field

[0001] The present invention belongs to the technical field of orange juice processing equipment, and particularly relates to a peeling assembly for peeling oranges, which is mainly used for the peeling process before squeezing juice from oranges. Background Art

[0002] Oranges are important raw material fruits for producing fresh fruit juice and various fruit juice beverages. Various orange juices and fruit granule beverages based on oranges are widely loved by consumers and have extremely high market value. In the production process of beverages such as orange juice, it is necessary to extract the juice rich in various nutrients such as vitamins from oranges, and squeezing oranges is the most widely used method at present. However, if the method of squeezing with the peel is adopted, the essential oil composed of substances such as limonene in the secretory cavities of the orange peel will also be collected in the squeezed liquid together with the pulp juice. Substances such as essential oil and tannic acid in the orange peel that are squeezed out and mixed into the fresh orange juice often have obvious peculiar smells, such as bitterness, astringency, etc. And the addition of these substances will greatly reduce the taste of the orange juice. And it is also very difficult to separate such substances in the subsequent processes. And covering or treating the above substances by using food additives will undoubtedly reduce the purchasing willingness of consumers and increase the production cost.

[0003] To solve the above problems, it is necessary to peel the oranges, and at present, peeling the oranges has become an essential step to obtain a good taste. Traditional peeling is mainly carried out manually by peeling, obviously this method has low efficiency and high cost, and this method can no longer meet the needs of modern production. With the continuous progress of modern food automation production technology, using automated mechanical equipment for peeling has gradually become the mainstream method of fruit peeling. At present, using machinery to peel oranges is mainly divided into two types: peeling and skinning, and the former is the mainstream. Oranges are different from fruits such as apples and pears whose peels are tightly combined with the flesh. Its peel and flesh are separable. At the same time, oranges are different from tangerines. The degree of combination between the peel and flesh of oranges is often much greater than that of tangerines. Therefore, this brings great technical difficulties to removing the orange peel. However, because oranges are ellipsoidal structures with a very small major axis ratio close to a sphere and are basically symmetrical, they can completely form a rotating body driven by a motor at high speed. This brings great convenience to the cutting and peeling of external tools. Therefore, the vast majority of existing orange peeling devices use the method of peeling, and this method has relatively high peeling effect.

[0004] However, the turning and peeling method generally can only perform one cutting operation, which often leads to the problem of insufficient peeling. Typically, yellow and white stripes are produced, where the yellow color is the unpeeled orange peel. Such raw materials put into subsequent processing will undoubtedly seriously affect the taste of the product. When using the secondary cutting method, it is often difficult to control the cutting depth, resulting in a large amount of pulp being cut off and causing waste of resources.

[0005] To solve the above technical problems existing in the turning and peeling equipment, Zhang Haokun et al. from Kunming University of Science and Technology developed a peeling-type orange peeler (application number: 202220723913.6). The orange peeler includes a device housing, a moving mechanism, peeling claws, and a skin storage box. Among them, the device housing includes an upper housing and a lower housing. One side of the bottom of the upper housing is hinged to the top of one side of the lower housing, and the skin storage box is arranged at the bottom of the other side of the lower housing. The moving mechanism includes an upper push rod and a lower push rod that can move up and down and rotate inside the upper and lower housings. Among them, a peeling claw is arranged at the lower end of the upper push rod. The peeling claw includes six peeling fingers, and a retractable blade is provided at the fingertip of the peeling finger. The upper end of the peeling finger is connected to the upper push rod through components such as a spring and a connecting rod. Thus, through the up and down movement of the upper and lower push rods, the orange peel is divided by the blade around the fingertip of the peeling claw on the outer skin of the orange. Then, the peeled orange peel is peeled off by the peeling fingertip.

[0006] Although the above orange peeler can complete the peeling-type peeling of oranges through delicate design, it obviously has the following defects:

[0007] First, the device adopts a single-piece structure, and the entire structure can only process oranges in an intermittent manner, that is, it is necessary for the operator to place the oranges one by one in the accurate position before subsequent operations can be carried out. Obviously, this is not conducive to industrial assembly-line production and the work efficiency is not high;

[0008] Second, compared with the traditional cutting-type peeling equipment, although the device realizes peeling-type peeling, its structure is obviously too complex and the manufacturing cost is relatively high. Summary of the Invention

[0009] (1) Technical problems to be solved

[0010] The present invention aims to solve one of the following technical problems existing in the prior art or related technologies:

[0011] The problems that the existing peeling-type peeling devices for oranges have a single-piece design, resulting in that the operator can only operate one by one, which is not suitable for industrial assembly-line production, has low work efficiency, and has a complex structure and high manufacturing cost.

[0033] Preferably, the elastic member 16 is a spring or a cylinder.

[0034] (III) Beneficial Effects

[0035] Compared with the prior art, the beneficial effects obtained by the present invention are as follows:

[0036] 1. The peeling component provided by the present invention can be highly adapted to the existing orange juice peeling production line. It not only has high working efficiency, but also requires few modifications to the existing production line and has low equipment transformation costs. After the orange goes through the top-peeling process, the component drives the cutter to move along the outer surface of the orange peel under the drive of the motor and divides the orange peel. Since the orange at the bottom inserted on the production line rotates under the drive of the motor during the division process, the cutter will form a variable-diameter spiral division mark on the orange peel. The peeling knife located in the downstream section of the cutter will accurately insert into the fibrous soft tissue layer between the yellow hard layer and the pulp layer of the orange peel under the drive of the motor rotation. Since the cutter has already cut and damaged the integrity of the orange peel at this location before the peeling knife touches the downstream fibrous soft tissue layer, the peeling knife can more easily divide the fibrous soft tissue layer, and then the orange peel can be peeled off.

[0037] 2. The structure of the peeling component provided by the present invention is simple, which only consists of a few components such as a cutter, a peeling knife, an elastic member, two connecting rods and a motor. The manufacturing and maintenance costs are low, and there is no need for too many transmission components and the cooperation of a large number of components, so the failure rate is also low.

[0038] 3. In the peeling component, an elastic member is installed between the first connecting rod and the second connecting rod which are rotatably connected. The elastic member can restrict the angle between the two connecting rods, so that the cutter and the peeling knife connected to the end of the first connecting rod can fit on the outer periphery of the orange peel for cutting and peeling.

[0039] 4. In the peeling component, the cutter and the peeling knife are connected to the end of the first connecting rod, and there is a spacing between them. During the rotation of the cutter and the peeling knife, this spacing section will turn through a certain arc. The cutting depth of the cutter tip is slightly greater than the thickness of the orange peel, so as to maximize the destruction of the overall stability of the orange peel. The bottom surface position of the peeling knife is lower than the cutting depth of the cutter tip section, and as it rotates, the bottom surface of the peeling knife will first press on the plane of the orange after the top is removed. This "pressing" will cause a certain degree of separation between the pulp part and the orange peel part at the edge position of the orange top surface, which is convenient for the peeling knife to insert into the lower part of the orange peel. At the same time, the front part of the peeling knife protrudes and will first contact the edge part with a cut. When the front part of the peeling knife inserts under the orange peel with a cut, it will "open" the cut, causing the orange peel on both sides of the cut to be completely separated, which is beneficial to the subsequent peeling of the orange peel. Since at the initial stage of the cut, the width of the peeled orange peel gradually increases, the dividing part on the peeling knife with a width greater than the maximum width of the peeled orange peel is conducive to peeling the rotated part of the orange peel as a whole, thus avoiding the problem of partial non-peeling of the orange peel. In addition, the bottom surface of the peeling knife is an arc surface with a curvature similar to that of the orange, which can make the peeling knife fit the pulp part of the orange to the greatest extent during the peeling process to prevent the orange peel from breaking during the peeling process.

[0040] V. In the peeling assembly, the bottom of the peeling knife is an arc portion with a radius of curvature approximately equal to the outer curvature radius of the orange peel, so that the peeling knife can be as close as possible to the outside of the pulp layer of the orange during movement. At the same time, the side of the peeling knife facing the orange peel adopts an arc structure to facilitate the separation and cutting of the fibrous soft tissue layer.

[0061] The embodiments of the present invention will be described in detail below with reference to the drawings. However, the present invention can be implemented in many different embodiments defined and covered by the claims.

[0062] In the following description of the present invention, it should be noted that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and "vertical" and other terms indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be construed as a limitation of the present invention.

[0063] In the following description of the present invention, it should be noted that, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] In addition, in the following description of the present invention, unless otherwise specified, the meanings of "multiple", "multiple groups", and "multiple roots" are two or more.

[0065] Figure 1 Schematically shown is the variable-diameter spiral-shaped cut mark formed along the orange peel after the top-peeled orange in the present invention is rotationally divided by a cutter. In the existing rotary peeling equipment, the orange generally goes through three steps: top-peeling, peeling, and bottom-peeling. From Figure 1 it can be seen that after removing the top orange peel, a horizontal plane appears at the upper part of the orange. Since during the peeling process, the orange is connected to the motor through the bottom fixing component and rotates under the drive of the motor. At this time, when the peeling component moves along the direction perpendicular to the plane where the rotation direction is located and fits the surface of the orange, a variable-diameter spiral-shaped cut seam D1 as shown in the figure will be formed. The cut seam D1 divides the orange peel into strip-shaped sections wrapped outside the pulp. Among them, the width of the front part of the divided orange peel gradually increases to the maximum width, and the rear part is cut at the limit position of cutting due to its small width. The existence of the cut seam D1 causes the destruction of the overall structure of the orange peel and greatly increases the success probability of peeling and removing the orange peel.

[0066] Figure 2 Schematically shown is a partial three-dimensional structure diagram of the peeling component on the peeling production line in a preferred embodiment of the present invention. From Figure 2 it can be seen that during the production process, the orange peeling is processed in a pipeline manner from left to right. At the bottom of this figure is the transmission component 4, that is, a transmission belt driven by a power mechanism, which drives the peeling component 1, the top-removing component 2, the fixing component 3, etc. to move. Among them, the bottom of the fixing component 3 is introduced from its bottom to the upper part through a bearing provided on the transmission belt, and multiple fixing needles are provided on the upper part of its cylindrical rotating shaft. During operation, the orange to be peeled can be pressed on the fixing needles manually or mechanically, so as to fix the orange.

[0067] After being fixed by the fixing component 3, the orange moves to the workstation of the topping component 2. The topping component 2 includes a moving block 21, a fixed rod 22, a rotating rod 23 and a peeling knife 24. The moving block 21 is fixedly connected to the fixed rod 22 and movably connected to the rotating rod 23 through a shaft sleeve. The peeling knife 24 is installed at the bottom end of the rotating rod 23. A screw (not shown) is also provided on the upper part of the moving block 21 to push it back and forth in the vertical direction, and a motor (not shown) is connected to the upper part of the rotating rod 23 to enable it to rotate. Among them, components such as the screw and the motor are integrated into the equipment box on the assembly line. After the orange moves to this workstation, the screw pushes the moving block 21 to move down and support the upper part of the complete orange S1. Then, the motor drives the peeling knife 24 to rotate, thereby peeling the top skin of the orange. After the action is completed, it resets, and the orange then moves to the workstation where the peeling component 1 is located.

[0068] The peeling assembly 1 includes a first connecting rod 11, a second connecting rod 12, a power mechanism 13, a cutting knife 14, a peeling knife 15, an elastic member 16, and a first connecting plate 17. The first connecting plate 17 is used to be fixedly connected to the top box, side wall, or bracket of the assembly line to achieve the fixation of the peeling assembly. The power mechanism 13 is fixedly connected to the first connecting plate 17, and its output shaft is fixedly connected to the bottom of the second connecting rod 12, thereby driving its rotation. The upper part of the second connecting rod 12 is rotatably connected to the first connecting rod 11 via a pin. The first connecting rod 11 is a T-shaped structure, and the cutting knife 14 and the peeling knife 15 serving as the peeling actuator are installed at its transverse front end. In order to control the angle of the first connecting rod 11 and the second connecting rod 12 so that they fit better on the orange during the peeling process, an elastic member 16 is connected between the two.

[0069] Figure 3 The three-dimensional structure of the peeling assembly before peeling the orange peel in a preferred embodiment of the present invention is schematically shown. Figure 4 for Figure 3 Schematic diagram of the front view structure. Figure 5 for Figure 3 Schematic diagram of the rear view structure. Figure 3-5 It can be seen that in this preferred embodiment, there is a 90-degree angle between the first connecting rod 11 and the second connecting rod 12. When the orange enters the predetermined work station from the side of the cutter 14, if the top peel is not thrown off by the peeling knife 24, it will be pushed off by the cutter 14 to avoid the top peel affecting the subsequent process. The cutter 14 is set with the tip and blade tilted downward to facilitate the division of the orange peel and prevent it from producing a peeling effect due to the blade being too long during cutting. At the same time, the inclined setting is conducive to increasing the cutting depth, and the actual cutting depth can slightly exceed the peel layer to ensure that the orange peel is thoroughly divided. The main body of the peeling knife 15 is a trapezoidal structure, with an arc-shaped blade at the front that faces the orange peel during the peeling process, and is fixedly connected to the first connecting rod 11 at the rear through a vertical connecting plate. From Figure 5As can be seen, there's an 8mm gap between cutter 14 and peeler 15, and the lowest position of cutter 14 is slightly lower than the lowest position of peeler 15. This allows the front edge of cutter 14 to penetrate the orange peel more deeply than peeler 15, ensuring complete penetration. Furthermore, the aforementioned gap, rotation angle, and curved bottom surface of peeler 15 facilitate peeler 15's engagement with the top flesh before penetrating into the fibrous soft tissue layer between the outer yellow, hard layer and the flesh of the orange peel. To ensure a better fit between peeler 15 and cutter 14 during peeling, the position of power mechanism 13 can be slightly offset from the orange's central axis, thereby increasing its rotational radius and allowing elastic member 16 to pull on first connecting rod 11.

[0070] Figure 6 The structure diagram of the first connecting rod of the peeling assembly in a preferred embodiment of the present invention is schematically shown. Figure 6 As can be seen, in this preferred embodiment, the first connecting rod 11 has a T-shaped structure. Its main body consists of a rotating portion 111 and a first connecting portion 112. A through-hole 116 is provided at the free end of the rotating portion 111 for rotational connection with the second connecting rod 12. A second connecting portion 113 with a through-hole is provided at the lower portion of the rotating portion 111 to facilitate connection with the elastic member 16. Two fixing holes are provided at each end of the first connecting portion 112: a first fixing hole 114 for connection with the cutting knife 14 and a second fixing hole 115 for fixed connection with the skinning knife 15.

[0071] Figure The structure diagram of the cutter of the peeling assembly in a preferred embodiment of the present invention is schematically shown. 7 As can be seen, in this preferred embodiment, the cutting blade 14 has a circular third fixing hole 143 on the cutting blade body 141 for connecting to the fixing hole on the first connecting portion 112 of the first connecting rod 11. Behind the third fixing hole 143, there is also an arc-shaped slot, namely the first slot 144. This slot allows the inclination angle of the cutting blade 14 to be changed by changing the bolt fixing position.

[0072] Figure 7 The figure schematically shows a three-dimensional wire frame diagram of a peeling knife in a preferred embodiment of the present invention. Figure 8It can be seen that in this preferred embodiment, the peeling knife 15 is composed of a peeling knife body 151 with a trapezoid-like thin wall and a second connecting plate 152 perpendicular (or nearly perpendicular) to it, and the two are integrally formed. Among them, a circular fixing hole (the fourth fixing hole 154) and an arc-shaped slot hole (i.e., the second slot hole 155) are provided in the upper part of the connecting plate 152, and the two are used for fixedly connecting with the first connecting part 112 of the first connecting rod 11 and adjusting the inclination angle of the peeling knife body 151. The plane where the peeling knife body 151 is located can have an included angle of ±10° with the top plane of the de-topped orange. The front part of the peeling knife body 151 is an inwardly concave arc-shaped dividing part 153, and a cutting angle 156 is provided at the arc-shaped end facing the cutting knife 14, so as to prevent the peeling knife 15 from directly causing the fracture at the starting point of the cutting seam when inserted between the orange peel and the pulp. To fit the surface of the orange, the bottom of the peeling knife body 151 can adopt an arc surface 158. When its thickness is insufficient, the whole peeling knife body 151 can be bent to form an arc surface with a curvature radius of 40 mm - 60 mm. On both sides of the peeling knife body 151, the inner edge of the second connecting plate 152 is rounded to avoid cutting the adjacent orange peel during peeling. And the outer side without the second connecting plate 152 is preferably chamfered.

[0073] Figure 8 FIG. shows a three-dimensional structural diagram of the peeling assembly in the second preferred embodiment of the present invention schematically. Figure 9 For Figure 10 the front view structural schematic diagram of. Figure 9 Shown schematically Figure 11 a three-dimensional structural diagram of the peeling knife in the peeling assembly. It can be seen from Figure 9 that in this preferred embodiment, the overall structure of the peeling assembly 2 is basically the same as that shown in Figure 9-11 Figure 3 , the difference being that: the peeling knife 15 is improved, the connection part of the first connecting rod 11 is changed, and at the same time, a new connecting piece is added. The peeling knife 15 adopts the form of a human finger, the dividing part at its front end is a structure with a circular arc protruding backward, and the knife body at the rear side has an arc-shaped configuration on both the side surface and the bottom surface. In this way, the connection between the orange peel and the pulp is gradually torn and broken through the edge at the front end of the peeling knife and the gradually thickening dividing part of the peeling knife. A plane is cut out on the upper surface of the knife body, and a connection hole for connecting with the first connecting rod 11 is opened on this plane. A cross plate 17 is provided at the position of the first connecting rod 11 for connecting the peeling knife 15, and a long strip-shaped straight slot hole 118 is provided on the cross plate 17. The peeling knife 15 is connected with the straight slot hole 118 through a threaded rod 18. At the same time, a guide plate 19 is provided between the lower surface of the cross plate 17 and the peeling knife 15 to facilitate guiding the peeled orange peel and prevent winding from affecting the normal peeling process.

[0074] The working process of the peeling assembly is as follows: After the orange is topped, a topped orange with a top plane is formed and sent to the peeling assembly station by the transmission assembly. The power mechanism of the peeling assembly rotates its output shaft to divide and peel the orange rotating in front of its station. The motor serving as the power mechanism rotates the output shaft in the reverse direction of the production line by a predetermined angle, driving the second connecting rod and the first connecting rod to rotate, so that the cutter and the peeling knife connected to the end of the first connecting rod fit the orange peel to move. Specifically, the cutter located in the upstream position first cuts the orange peel driven by the first connecting rod, and with the help of its own movement track and the rotation of the orange, a variable-diameter spiral cut is made on the orange peel, thus destroying the integrity of the orange peel. The peeling knife located in the downstream position is inserted into the fibrous soft tissue layer between the yellow hard outer layer of the orange peel and the pulp as the first connecting rod rotates, and thus the fibrous soft tissue layer is cut off by the dividing part on the peeling knife. The bottom of the peeling knife body is a curved surface with a curvature radius close to that of the orange, which can make it better fit the orange. When the peeling knife body starts to rotate, it first fits the top pulp with the rotation and can cause a certain degree of extrusion to the pulp at this part (since there is a distance between the cutter and the peeling knife, the knife body can reduce the distance from the cut entrance with the rotation to avoid the peeling knife cutting into the pulp), and under the action of the "blanking" cut of the peeling knife at the front end, the arc of the peeling knife gradually cuts into the fibrous soft tissue layer, and then the separation of the flesh and the peel of the orange is realized with the rotation of the orange and the rotation of the knife body. At the same time, the elastic member connected between the first connecting rod and the second connecting rod at both ends contracts to keep the cutter pressing on the orange peel, so as to ensure that the cutter and the peeling knife, as the peeling execution mechanism, can perfectly fit the orange. After the orange is peeled, the peeled orange moves to the next station by the transmission assembly, and the unpeeled bottom peel is removed manually or mechanically. At the same time, the peeling assembly is reset driven by the power mechanism to facilitate the peeling process of the next orange.

[0075] The above peeling assembly performs the peeling operation, which not only has the advantages of efficient processing through rotation in the existing peeling operation, but also realizes the peeling-type peeling operation on the orange through the peeling knife, maximizing the avoidance of the problem that the individual orange peel cannot be removed cleanly in the peeling operation, which affects the quality of the subsequent product.

[0076] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
