Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural product processing machinery, in particular to a tear opening and peeling device for dried orange peel production. BACKGROUND

[0002] Dried orange peel, as a traditional medicine and food material, has a long history of food and medicine use. The production process of dried orange peel is very particular, and the most core process is peeling. Traditional high-quality dried orange peel requires that the peel be evenly divided into three pieces and peeled off while keeping the base of the peel connected, and the internal pulp should not be damaged during peeling to avoid contamination of the peel by juice flowing out, so as to retain the integrity of the peel and the content of volatile oil.

[0003] At present, the peeling process of dried orange peel is mainly performed by skilled workers using tools to scratch, pry and tear the peel. Although manual peeling can better ensure the shape of the peel and not damage the pulp, it has problems such as high labor intensity, low production efficiency, difficult control of sanitary conditions, and high labor cost, which makes it difficult to meet the needs of large-scale industrial production.

[0004] There are also some peelers on the market, such as using a rotary knife to spiral cut the fruit, or using a rigid knife to directly punch or cut. Although the efficiency is high, the peel peeled off by these machines destroys the traditional "three-piece connection" structure of dried orange peel, resulting in a decrease in product grade, which cannot meet the process requirements of specific markets, and the tools of such machines are easy to cut the pulp sac, causing juice to spill out, affecting the color and quality of dried orange peel.

[0005] In addition, when existing technologies achieve automatic peeling, fresh citrus peel has strong toughness and elastic memory. After being peeled off by a machine, it often automatically closes and rewraps the pulp, which makes the subsequent pulp removal process difficult, often requiring additional manual work to open the peel again, which seriously restricts the full automation process of the production line.

Detailed Implementation

[0027] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0028] like Figures 1 to 8 As shown in the figure, this embodiment discloses a tearing and peeling device for making dried tangerine peel, which mainly includes a frame (not shown), a positioning base 20 set on the frame, a lifting main frame 30 that can be vertically raised and lowered relative to the frame, and several working components integrated and installed on the lifting main frame 30.

[0029] The frame structure serves as the fixed support body of the device. The positioning base 20 is installed in the bottom center area of ​​the frame and is configured to support and position the citrus fruit 100 to be processed. The lifting main frame 30 is slidably connected to the frame in the vertical direction through a guide mechanism. The frame is also equipped with a lifting drive mechanism such as a lead screw motor module 10, the output end of which is connected to the lifting main frame 30 to drive the lifting main frame 30 to move up and down relative to the positioning base 20.

[0030] like Figure 1 , Figure 4 , Figure 7 As shown, to adapt to the traditional "three-petal blooming" process in the production of dried tangerine peel, the lifting main frame 30 in this embodiment adopts a ring frame structure, with the slicing blade assembly 40 and the peeling operation unit staggered along the circumference of the ring frame. Specifically, the number of peeling operation units is set to three groups, which are arranged at 120-degree intervals along the circumference of the lifting main frame 30; correspondingly, the number of slicing blade assemblies 40 is also three groups, with each group of slicing blade assemblies 40 respectively set at the circumferential gap between two adjacent groups of peeling operation units, thereby forming a staggered layout of three cuts and three peels to achieve uniform three-part processing of the peel of the citrus fruit 100.

[0031] In some embodiments, such as Figure 3 , Figure 4 As shown, the slicing blade assembly 40 is configured to descend synchronously with the lifting main frame 30 and make several longitudinal cuts on the peel of the citrus fruit 100 to define the boundary of the subsequent peeling operation. Taking the production of three-lobed tangerine peel in this embodiment as an example, the number of slicing blade assemblies 40 is set to three sets, corresponding to the formation of three longitudinal cuts on the fruit surface. The subsequent peeling operation unit is configured to peel off the peel area between two adjacent longitudinal cuts. It should be noted that the number of slicing blade assemblies 40 is not limited to three sets. In practical applications, it can be set to four or more sets according to the product's process customization requirements, such as four-lobed or five-lobed tangerine peel. This application does not make specific limitations in this regard.

[0032] In specific implementation, such as Figure 4 As shown, the slicing assembly 40 includes a blade holder 41, a blade shank 42, a blade head 43, a first tension spring 44, and a second tension spring 45. The blade holder 41 is fixedly mounted on the lifting main frame 30, serving as the supporting foundation for the assembly. The middle portion of the blade shank 42 is pivotally connected to the blade holder 41 via a pivot shaft, forming a lever-like structure. The middle portion of the blade head 43 is pivotally connected to the top of the blade shank 42 via a pivot shaft, and the blade head 43 has a cutting edge for cutting.

[0033] To achieve adaptive fitting for fruits of different diameters and ensure uniformity of cut depth: One end of the first tension spring 44 is connected to the bottom end of the blade 42, and the other end is connected to the blade holder 41. According to the lever principle, the first tension spring 44 is configured to apply a pulling force to the bottom end of the blade 42, that is, to pull the bottom end of the blade 42 outward, causing the top end of the blade 42 to tend to swing radially inward toward the center of the fruit 100, thereby providing pressure for the cutting edge of the blade head 43 to cut into the peel.

[0034] One end of the second tension spring 45 is connected to the blade head 43, and the other end is connected to the blade holder 41. Its function is to apply tension to the blade head 43 and restrict the degree of freedom of the blade head 43 to rotate around the top of the blade rod 42, so as to stabilize the posture of the blade head 43 when forming a longitudinal cut on the peel of the fruit 100, that is, to ensure that the cutting edge of the blade head 43 always cuts into the peel at a preset angle.

[0035] like Figure 1 , Figure 4 , Figure 5 As shown, each peeling unit includes a tearing clamping component 50. The main function of the tearing clamping component 50 is to pierce the peel at the top of the fruit and tear open the peeling starting point, creating conditions for subsequent operations.

[0036] Specifically, the tear-off clamping assembly 50 includes a digging plate 51, a clamping block 52, and a lateral traction drive unit 53 that drives the digging plate 51 and the clamping block 52 to generate lateral relative movement.

[0037] The digging plate 51 is configured to descend with the lifting main frame 30 and pierce the peel area between two adjacent longitudinal cuts. Specifically, the bottom end of the digging plate 51 is provided with an insertion cutting edge. In this embodiment, the cutting edge is formed by a V-shaped splicing of a vertically arranged first blade 511 and a second blade 512, for example, the first blade 511 and the second blade 512 are set at a 120-degree angle to precisely fit the shape of the peel area defined by the two adjacent longitudinal cuts.

[0038] The lateral traction drive unit 53 is configured to drive the clamping block 52 to cooperate with the digging plate 51 to clamp the top peel of the fruit 100 and pull it radially outward away from the center of the fruit 100, so that the peel is peeled off from the pulp based on the longitudinal cut. In this embodiment, the clamping block 52 is V-shaped to match the digging plate 51 or is provided with a silicone buffer layer to achieve flexible clamping of the peel and prevent the peel from being broken or damaged.

[0039] In this embodiment, as Figure 4 , Figure 5 As shown, the lateral traction drive unit 53 includes a first cylinder 531 fixedly installed on the lifting main frame 30. A mounting plate 532 is fixedly installed on the piston rod of the first cylinder 531. The mounting plate 532 is L-shaped. A second cylinder 533 located below the first cylinder 531 is fixedly installed on the mounting plate 532. That is, the second cylinder 533 and the first cylinder 531 are stacked to save space. The clamping block 52 is fixedly installed on the piston rod of the second cylinder 533. The digging plate 51 is fixedly installed on the mounting plate 532 and is configured to cooperate with the clamping block 52.

[0040] In some embodiments, the lateral traction drive unit 53 is configured to: before the drive clamp 52 and the digging plate 51 cooperate to clamp the top peel of the fruit 100, independently drive the digging plate 51 to move a predetermined distance radially outward away from the center of the fruit 100, so as to form a peeling opening for separating the peel from the pulp.

[0041] Specifically, when the lifting main frame 30 descends to a preset height, causing the digging plate 51 to pierce the skin between two adjacent cuts on the top of the fruit, the first cylinder 531 actuates first, driving the digging plate 51 to move radially outward a short predetermined distance, such as 5-15mm, to tear a slit in the peel at the top of the fruit, achieving initial separation of the peel from the flesh; then, the second cylinder 533 actuates, pushing the clamping block 52 toward the digging plate 51 to clamp the torn peel; finally, the first cylinder 531 continues to retract, driving the digging plate 51 and the clamping block 52 to move outward as a whole, completely pulling the top of the peel away from the flesh.

[0042] In some preferred embodiments, as the first cylinder 531 continues to retract, the lifting main frame 30 simultaneously drives the tearing clamping assembly 50 to descend. At this time, the digging plate 51 and the clamping block 52 actually perform a downward composite motion trajectory, that is, they have both horizontal outward and vertical downward displacement components. This composite motion conforms to the natural path of peeling, which can effectively improve the smoothness and effect of peel separation.

[0043] In some embodiments, such as Figure 1 , Figure 2As shown, each peeling unit also includes a contour peeling component 60, which is configured to insert into the gap between the peel and the pulp after the tearing clamping component 50 pulls the top peel apart, and work in conjunction with the action of the digging plate 51 and the clamping block 52 to completely peel off the remaining peel.

[0044] Specifically, the contour peeling assembly 60 mainly includes a guide template 61, a peeling plate 62, a guide mating component 63, and an independent lifting drive unit 64 that drives the peeling plate 62 to move vertically relative to the lifting main frame 30. In this embodiment, the independent lifting drive unit 64 is a vertically mounted cylinder.

[0045] In this embodiment, two guide templates 61 are arranged opposite each other, and a variable curvature guide groove 611 is provided on the surface of each guide template 61. The shape of the variable curvature guide groove 611 corresponds to the radial outer contour of the fruit 100. That is, at least part of the trajectory shape of the variable curvature guide groove 611 is set according to the contour characteristics of the citrus fruit, which is small at both ends and large in the middle.

[0046] The peeling plate 62 is slidably engaged with the variable curvature guide groove 611 through the guide fitting 63. Specifically, the guide fitting 63 is a pin that is slidably inserted into the two guide templates 61 to counteract the variable curvature guide groove 611, so that the peeling plate 62 has a contouring motion trajectory defined by the variable curvature guide groove 611.

[0047] The independent lifting drive unit 64 is configured such that, during the process of pulling the peel radially outward away from the center of the fruit 100, it drives the peeling plate 62 to descend along the contour movement trajectory, inserting between the separated peel and pulp, and moving along the outer contour of the fruit 100 to peel the peel from the pulp surface. This reduces the tension on the peel when the digging plate 51 and clamping block 52 hold the peel and move it outward as a whole, effectively avoiding the risk of the peel being torn or broken.

[0048] In some embodiments, such as Figure 2 , Figure 4 , Figure 6 As shown, the output end of the independent lifting drive unit 64 is pivotally connected to a wheel frame 65, and the wheel frame 65 is vertically spaced with a first guide wheel 66 and a second guide wheel 67; the top of the peeling plate 62 is provided with a horizontally extending straight section 621, which slides between the first guide wheel 66 and the second guide wheel 67 and is fixedly connected to the guide mating member 63; an elastic member 68 is connected between the straight section 621 and the wheel frame 65.

[0049] When the independent lifting drive unit 64 drives the wheel frame 65 to descend vertically, the guide wheel presses the peeling plate 62 to descend. At the same time, due to the restriction of the variable curvature guide groove 611, the peeling plate 62 will have horizontal forward and backward displacement. At this time, the straight section 621 will perform adaptive sliding extension and retraction between the two guide wheels.

[0050] In this embodiment, as Figure 4 , Figure 6 As shown, two variable curvature guide grooves 611 are arranged at intervals on the same guide template 61, and two guide mating parts 63 are provided corresponding to the variable curvature guide grooves 611. The position of the elastic element 68 connecting the straight section 621 is located between the two guide mating parts 63 to ensure the smoothness of the movement.

[0051] In some embodiments, such as Figure 3 , Figure 8 As shown, the positioning base 20 includes a citrus support cylinder 22 that can be replaced according to the size of the fruit, and elastic blocking members 21 arranged circumferentially on the left and right sides of the peeling unit. Preferably, the elastic blocking members 21 are made of stainless steel springs with good resilience.

[0052] In this design, the descent stroke of the peeling plate 62 is set to be longer than the height of the fruit. After the peeling plate 62 completes the separation of the pulp, it continues to move downward, forcibly pushing the peeled peel over the upper surface of the elastic barrier 21. When the peel is pressed below the elastic barrier 21, the elastic barrier 21 loses its compression and elastically resets, with its lower surface (or side edge) abutting against the inner side (or upper edge) of the peel, thereby mechanically locking the peeled peel in an unfolded state and preventing it from retracting and wrapping around the pulp due to its own bioelasticity. This design eliminates the need for additional downward pressure rods, achieving a simplified structure.

[0053] In summary, the complete operation process of this device is as follows: S1 Loading: Place the citrus fruits 100 to be processed onto the citrus support tube 22 of the positioning base 20.

[0054] S2 Scratching: As the lifting main frame 30 descends, the scratching knife assembly 40, under the action of the double spring floating mechanism, scratches three longitudinal cuts close to the surface of the fruit.

[0055] S3 Insertion and Pre-expansion: The lifting main frame 30 is lowered to the bottom, and the digging plate 51 inserts into the top skin of the fruit; the first cylinder 531 moves slightly to tear open the initial crack.

[0056] S4 Clamping and Traction: The second cylinder 533 actuates, cooperating with the digging plate 51 to clamp the fruit peel; then the first cylinder 531 retracts, pulling the top of the fruit peel outward.

[0057] S5 Contouring Peeling: The independent lifting drive unit 64 is activated, driving the peeling plate 62 to descend along the contour trajectory, completely scraping the peel off the fruit pulp.

[0058] S6 Locking and Resetting: The peeling plate 62 continues to descend, pressing the peel under the elastic blocking member 21 and locking it; then each cylinder and drive unit resets, the lifting main frame 30 rises, the pulp is removed, and the dried tangerine peel retains its three-lobed unfolded shape.

[0059] The tearing and peeling device for making dried tangerine peel provided in this application embodiment uses the lateral traction action of the tearing clamping component to pre-pull the peel outward from the pulp based on the longitudinal cuts to form a peeling opening. The variable curvature guide groove of the guide template restricts the peeling plate to generate a contour-following motion trajectory that conforms to the fruit's outline, allowing the peeling plate to accurately insert into the gap between the peel and pulp and complete the peeling. This device achieves a mechanical replication of the manual widening and arc-surface peeling actions, ensuring the integrity of the three segments of the dried tangerine peel while avoiding the compression damage to the internal pulp caused by rigid cutting. It solves the technical problem of mechanical peeling being unable to simultaneously achieve fruit shape adaptability and pulp protection.
