Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a device for removing black edges from yellow persimmons. Background Technology

[0002] In the deep processing of yellow persimmons, the navel, stem, and the black edges surrounding them must be removed. The stem is hard and fibrous, directly affecting the taste of the product; the navel is prone to retaining impurities, increasing the difficulty of cleaning and potentially breeding microorganisms; the black edges, due to pigment deposition, have a bitter taste, and if not completely removed, will seriously reduce the sensory quality and eating experience of the final product. Therefore, the precise removal of these parts is one of the core steps in the pre-processing of yellow persimmons.

[0003] Currently, the removal of the navel, stem, and black edges of yellow persimmons mainly relies on workers manually removing these parts one by one using a small knife or a special scraper. This method has the following problems: workers need to repeat the "holding fruit-positioning-cutting" action for a long time, which is labor-intensive and can easily lead to occupational injuries such as hand fatigue and wrist strain; at the same time, there is a safety risk of cutting fingers when operating with a knife. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a device for removing black edges from yellow persimmons, comprising: The lower resection device includes a second power device and a resection mechanism, wherein the second power device drives the resection mechanism to move vertically. An upper resection device is disposed above a lower resection device. The upper resection device includes a first power device and a resection mechanism. The first power device drives the resection mechanism to move vertically. The resection mechanism includes: Third power unit; The blade is driven to rotate along its central axis by a third power device.

[0005] The first power unit of the upper cutting device and the second power unit of the lower cutting device drive the cutting mechanism to achieve vertical linear movement. In conjunction with the third power unit in the cutting mechanism, the blade is driven to rotate along its own central axis to complete the cutting action, thereby removing the fruit navel, fruit stem and black edge. Compared with the manual processing method, this improves processing efficiency, reduces the long-term repetitive operation of workers holding the knife, reduces labor intensity, and improves occupational injuries such as hand fatigue and wrist joint strain caused by repetitive movements. It also reduces the safety risk of cutting fingers when manually holding the knife.

[0006] Furthermore, the blade is an integral arc-shaped curved surface structure, which includes a base, a transition arc, and a cutting edge in sequence along its length. The transition arc connects the base and the cutting edge, and extends in an arc shape. The curvature of the transition arc gradually changes from one end near the base to the other end near the cutting edge. Both opposite sides of the transition arc are arc-shaped curved surfaces. The cutting edge is located at the end of the transition arc and is tapered. The edge of the cutting edge forms a sharp cutting edge. The thickness of the cutting edge gradually decreases in the direction away from the transition arc until the cutting edge.

[0007] The blade features a one-piece arc-shaped curved surface structure. The transition arc extends in an arc shape, with the curvature gradually changing from the base to the blade tip. Both opposite sides are arc-shaped, conforming to the arc contours of the persimmon's navel, stem, and black edge. This allows the blade to closely follow the shape of the area to be cut, reducing problems such as insufficient removal leading to black edge residue or incomplete stem removal, or excessive removal leading to excessive fruit loss, thus improving the utilization rate of persimmon raw materials. The blade tip is tapered, with its thickness gradually thinning away from the transition arc to a sharp cutting edge. This allows for cutting different tissues, such as the hard stem and the thinner black edge, reducing pressure or pulling damage to the persimmon flesh during cutting and lowering the fruit breakage rate.

[0008] Furthermore, the cutting mechanism also includes a power box, in which the third power device is installed. The blades are provided in multiple sets, and each set of blades is mounted on a connecting shaft that rotates relative to the power box via a connecting block. Adjacent sets of connecting shafts are connected by a transmission mechanism, and the third power device is connected to one set of connecting shafts via the transmission mechanism.

[0009] By setting multiple sets of blades, each set of blades is installed on the connecting shaft via a connecting block, and adjacent connecting shafts are connected by a transmission mechanism and driven by the same third power device, multiple sets of blades can be driven to rotate synchronously along their own central axis, thus achieving synchronous cutting of multiple persimmons.

[0010] Furthermore, the upper cutting device also includes a pressing structure, which is driven to move vertically by a first power device. The pressing structure includes a pressing plate, which is set below the cutting mechanism of the upper cutting device. An upper positioning hole is provided on the pressing plate corresponding to the blade. A pressing part is provided above the upper positioning hole and is fixed on the pressing plate. The inner side of the pressing part matches the upper part, and the pressing part has a stem-exposing hole corresponding to the fruit stem.

[0011] Furthermore, the clamping structure also includes a guide rod, which is fixed to the upper surface of the clamping plate. The guide rod passes through the power box from bottom to top and slides relative to the power box. An elastic element fitted on the guide rod is provided between the clamping plate and the power box of the upper cutting device.

[0012] The use of a single primary power unit to synchronously drive the cutting mechanism and clamping structure of the upper cutting device simplifies the layout of the equipment's power system, reduces the complexity of multi-power source synchronous control, and lowers equipment manufacturing costs and post-deployment debugging difficulty. The guide rod restricts the movement trajectory of the clamping structure, reducing lateral offset and tilting caused by fluctuations in the driving force of the primary power unit, fruit reaction force, or assembly errors. The elastic element fitted onto the guide rod absorbs the rigid driving force of the primary power unit through its own deformation when the clamping structure descends to fit the persimmon, reducing fruit pulp damage. After cutting, the elastic element synchronously returns to its natural extended state as the clamping structure ascends, assisting the primary power unit in quickly resuming the clamping structure. The exposed stem hole fully exposes the fruit stem, providing ample operating space for the blade to cut the stem. During clamping, the exposed stem hole prevents the clamping force from directly acting on the fruit stem and surrounding pulp, reducing damage and breakage caused by compression and lowering raw material loss.

[0013] Furthermore, the rejection device also includes a conveyor, with the upper rejection device positioned above the conveyor and the lower rejection device positioned below the conveyor's carrying section; The conveyor is a chain plate conveyor. The chain plate surface of the chain plate conveyor has a lower positioning hole corresponding to the blade. A support part is fixed below the lower positioning hole. The support part matches the lower part of the product. An exposed navel hole is provided on the support part at the position corresponding to the navel of the fruit.

[0014] The persimmons are conveyed by a conveyor. The upper cutting device cuts the stem and its surrounding black edge, while the lower cutting device cuts the navel and its surrounding black edge, thus achieving automatic removal of the navel, stem, and the black edge around it, improving work efficiency. The support part below the lower positioning hole matches the lower contour of the persimmon, providing support for the fruit and reducing longitudinal shaking during conveying or cutting. At the same time, the navel-exposing hole corresponding to the support part exposes the navel area, allowing the blades of the lower cutting device to act on the navel.

[0015] Furthermore, a flexible layer is provided on the inner side of the supporting part and the pressing part.

[0016] The flexible layer inside the supporting and pressing parts can form a flexible contact interface through its own deformation, avoiding rigid compression of the lower part of the fruit by the supporting part and the upper part of the fruit by the pressing part. It can provide stable support for the fruit during transportation and cutting, and also buffer the pressure when the second power device drives the pressing part, as well as the vibration and friction between the fruit and the supporting part during transportation, reducing problems such as skin indentation and pulp damage. In addition, the flexible layer has a certain degree of elastic deformation capability, which can adapt to the size differences and irregular shapes of yellow persimmons formed by natural growth. When pressing, the flexible layer can conform to the surface of the fruit, increasing the friction between the fruit and the supporting part and reducing the rotation and sliding of the fruit during cutting.

[0017] This utility model has the following advantages: The first power unit of the upper cutting device and the second power unit of the lower cutting device drive the cutting mechanism to achieve vertical linear movement. In conjunction with the third power unit in the cutting mechanism, the blade is driven to rotate along its own central axis to complete the cutting action, thereby removing the fruit navel, fruit stem and black edge. Compared with the manual processing method, this improves processing efficiency, reduces the long-term repetitive operation of workers holding the knife, reduces labor intensity, and improves occupational injuries such as hand fatigue and wrist joint strain caused by repetitive movements. It also reduces the safety risk of cutting fingers when manually holding the knife. Attached Figure Description

Detailed Implementation

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0020] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0021] As described in the background section, workers need to repeat the "holding fruit-positioning-cutting" action for a long time, which is labor-intensive and can easily cause occupational injuries such as hand fatigue and wrist strain. At the same time, there is a safety risk of cutting fingers when operating with a knife, and direct manual contact with the fruit increases the risk of microbial contamination, which does not meet the hygiene requirements of food processing and poses a safety hazard.

[0022] Example 1: Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a device for removing black edges from yellow persimmons, such as... Figure 1 , 2 As shown, the rejection device includes: Lower resection device 300, such as Figure 5 As shown, the lower resection device includes a second power unit 310 and a resection mechanism 500, and the resection mechanism is driven to move vertically by the second power unit. The upper cutting device 200 is disposed above the lower cutting device, such as... Figure 6 As shown, the upper resection device includes a first power unit 210 and a resection mechanism, and the first power unit drives the resection mechanism to move vertically. like Figure 8 , 9 As shown, the cutting mechanism includes: Third power unit 560; The blade 520 is driven to rotate along its central axis by a third power device.

[0023] Specifically, the first and second power units can be selected from cylinders, electric cylinders, hydraulic cylinders, or other devices capable of driving linear movement of components. The third power unit can be an electric motor. In this embodiment, the persimmons to be processed (persimmons that have been frozen and peeled) are manually fed to the processing station between the upper and lower cutting devices, with the stem facing upwards and the navel facing downwards. The third power unit in the cutting mechanism is activated, outputting torque to drive the blade connected to it to rotate along its own central axis. The first power unit of the upper cutting device is activated, outputting linear driving force to drive the cutting mechanism of the upper cutting device to move vertically downwards. As the cutting mechanism moves downwards, the rotating blade gradually contacts the stem of the persimmon and the upper black edge of the stem. Through the cutting action of the rotating blade, the stem and the upper black edge are removed. Simultaneously with the activation of the first power unit, the second power unit of the lower cutting device is activated. The second power unit outputs linear driving force, causing the cutting mechanism of the lower cutting device to move vertically upward. As the cutting mechanism moves upward, the rotating blade gradually contacts the navel and the black edge of the navel of the persimmon. Through the cutting action of the rotating blade, the navel and the lower black edge are removed simultaneously. After the stem, navel, and upper and lower black edges are removed, the cutting mechanism of the upper cutting device moves vertically upward under the drive of the first power unit and returns to the initial standby position. The cutting mechanism of the lower cutting device moves vertically downward under the drive of the second power unit and returns to the initial standby position. At the same time, the third power unit stops working, the blade stops rotating, and the persimmons with the black edges, stems, and navels removed are manually moved from the processing area and transferred to subsequent washing, sorting, or deep processing steps, completing a single operation of removing the black edges of the persimmons.

[0024] In addition, the upper cutting device may also include a frame 220, the first power unit may be fixedly installed on the top of the frame, and the cutting mechanism may be slidably connected to the frame through a guide mechanism (e.g., a slider-guide rail structure).

[0025] In this embodiment, the first power unit of the upper cutting device and the second power unit of the lower cutting device drive the cutting mechanism to achieve vertical linear movement. In conjunction with the third power unit in the cutting mechanism, the blade is driven to rotate along its own central axis to complete the cutting action, thereby removing the fruit navel, fruit stem and black edge. Compared with the manual processing method, this improves processing efficiency, reduces the long-term repetitive operation of workers holding the knife, reduces labor intensity, and improves occupational injuries such as hand fatigue and wrist joint strain caused by repetitive movements. It also reduces the safety risk of cutting fingers when manually holding the knife.

[0026] For example, the blade is an integral arc-shaped curved surface structure, which includes a base, a transition arc, and a cutting edge in sequence along its length. The transition arc connects the base and the cutting edge, and extends in an arc shape. The curvature of the transition arc gradually changes from one end near the base to the other end near the cutting edge. Both opposite sides of the transition arc are arc-shaped curved surfaces. The cutting edge is located at the end of the transition arc, is tapered, and has a sharp cutting edge at its edge. The thickness of the cutting edge gradually decreases in the direction away from the transition arc to the cutting edge.

[0027] The blade employs an integrated arc-shaped curved surface structure. The transition arc extends in an arc shape, with the curvature gradually changing from the base to the blade tip. Both opposite sides are arc-shaped surfaces, which can conform to the arc contours of the persimmon's navel, stem, and black edge. This allows the blade to closely follow the shape of the area to be cut, reducing problems such as insufficient removal leading to black edge residue or incomplete stem removal, or excessive removal leading to excessive fruit loss, thus improving the utilization rate of persimmon raw materials. The blade tip is tapered, with its thickness gradually thinning away from the transition arc to a sharp cutting edge. This allows for cutting different tissues, such as the hard stem and the thinner black edge, reducing pressure or pulling damage to the persimmon flesh during cutting and lowering the fruit breakage rate.

[0028] like Figure 8 , 9 As shown, the cutting mechanism also includes a power box 510, in which the third power device is installed. The blades are provided in multiple sets, and each set of blades is mounted on a connecting shaft 550 that rotates relative to the power box via a connecting block 530. Adjacent sets of connecting shafts are connected via a transmission mechanism 540, and the third power device is connected to one set of connecting shafts via the transmission mechanism.

[0029] By setting multiple sets of blades, each set of blades is installed on the connecting shaft via a connecting block, and adjacent connecting shafts are connected by a transmission mechanism and driven by the same third power device, multiple sets of blades can be driven to rotate synchronously along their own central axis, thus achieving synchronous cutting of multiple persimmons.

[0030] In this embodiment, as Figure 6 As shown, the upper cutting device also includes a clamping structure 230, which is driven to move vertically by a first power device, such as... Figure 7 As shown, the pressing structure includes a pressing plate 231, which is set below the cutting mechanism of the upper cutting device. An upper positioning hole is provided on the pressing plate corresponding to the blade. A pressing part 232 is provided above the upper positioning hole. The pressing part is fixed on the pressing plate. The inner side of the pressing part matches the upper part. The pressing part has a stem-exposing hole 233 corresponding to the fruit stem.

[0031] For example, the clamping structure further includes a guide rod 231, which is fixed to the upper surface of the clamping plate. The guide rod passes through the power box from bottom to top and slides relative to the power box. An elastic element fitted on the guide rod is provided between the clamping plate and the power box of the upper cutting device.

[0032] Specifically, the first power unit outputs a vertical driving force, which drives the clamping mechanism and the cutting mechanism of the upper cutting device to move downward in the vertical direction. As the clamping mechanism continues to descend, the inner side of the clamping part first contacts the upper part of the persimmon. At the moment of contact, the distance between the clamping plate and the power box decreases, and the elastic element is deformed by compression. The stem hole of the clamping part fits the stem of the persimmon, so that the stem is fully exposed. The first power unit maintains the current driving force and drives the cutting mechanism to continue to move downward, compressing the elastic element so that the clamping part maintains the clamping state on the persimmon until the cutting mechanism completes the cutting of the stem and the upper black edge.

[0033] The use of a single primary power unit to synchronously drive the cutting mechanism and clamping structure of the upper cutting device simplifies the layout of the equipment's power system, reduces the complexity of multi-power source synchronous control, and lowers equipment manufacturing costs and post-deployment debugging difficulty. The guide rod restricts the movement trajectory of the clamping structure, reducing lateral offset and tilting caused by fluctuations in the driving force of the primary power unit, fruit reaction force, or assembly errors. The elastic element fitted onto the guide rod absorbs the rigid driving force of the primary power unit through its own deformation when the clamping structure descends to fit the persimmon, reducing fruit pulp damage. After cutting, the elastic element synchronously returns to its natural extended state as the clamping structure ascends, assisting the primary power unit in quickly resuming the clamping structure. The exposed stem hole fully exposes the fruit stem, providing ample operating space for the blade to cut the stem. During clamping, the exposed stem hole prevents the clamping force from directly acting on the fruit stem and surrounding pulp, reducing damage and breakage caused by compression and lowering raw material loss.

[0034] like Figure 1 As shown, the rejection device also includes a conveyor 100, the upper rejection device is disposed above the conveyor, and the lower rejection device is disposed below the conveyor's carrying section; The conveyor is a chain plate conveyor. The chain plate surface of the chain plate conveyor has a lower positioning hole 111 corresponding to the blade. A support part 120 is fixed below the lower positioning hole. The support part matches the lower part of the product. An exposed navel hole 121 is provided on the support part at the position corresponding to the navel of the fruit.

[0035] The persimmons are conveyed by a conveyor. The upper cutting device cuts the stem and its surrounding black edge, while the lower cutting device cuts the navel and its surrounding black edge, thus achieving automatic removal of the navel, stem, and the black edge around it, improving work efficiency. The support part below the lower positioning hole matches the lower contour of the persimmon, providing support for the fruit and reducing longitudinal shaking during conveying or cutting. At the same time, the navel-exposing hole corresponding to the support part exposes the navel area, allowing the blades of the lower cutting device to act on the navel.

[0036] In this embodiment, a flexible layer is provided on the inner side of the supporting part and the pressing part.

[0037] The flexible layers (such as food-grade silicone or elastic rubber) on the inner sides of the supporting and pressing parts can form a flexible contact interface through their own deformation. This avoids rigid compression of the lower part of the fruit by the supporting part and the upper part of the fruit by the pressing part. It provides stable support for the fruit during transportation and cutting, and also buffers the pressure when the second power device drives the pressing part, as well as the vibration and friction between the fruit and the supporting part during transportation, reducing problems such as skin indentation and pulp damage. In addition, the flexible layer has a certain degree of elastic deformation capability, which can adapt to the size differences and irregular shapes of yellow persimmons formed by natural growth. When pressing, the flexible layer can adhere to the surface of the fruit, increasing the friction between the fruit and the supporting part and reducing the rotation and sliding of the fruit during cutting.

[0038] Specifically, the operator places the frozen and peeled persimmons one by one onto the support section of the chain conveyor, ensuring that the stem is facing upwards and the navel is downwards, with the navel embedded in the exposed navel hole of the support section. The conveyor is started, and the chain moves the persimmons along the conveying direction. When the persimmons are moved to the processing station between the upper and lower cutting devices, the conveyor stops running, and the third power unit is started. The third power unit drives a set of connecting shafts to rotate through the transmission mechanism. Adjacent connecting shafts are linked through the transmission mechanism, synchronously driving multiple sets of blades to rotate along their own central axis. The first power unit of the upper cutting device is started, and the first power unit outputs vertical driving force, driving the pressing structure and the upper cutting mechanism along the slider- The guide rail mechanism moves vertically downwards: the inner side of the clamping part (covered with a flexible layer) first contacts the upper part of the persimmon, and at the same time, the stem-exposing hole of the clamping part fits the stem, exposing it; the first power device maintains the driving force, driving the upper cutting mechanism to continue downwards (the clamping structure remains clamped due to the deformation of the elastic element), and at the same time, the second power device of the lower cutting device is activated: the rotating blade of the upper cutting mechanism moves downwards with the mechanism, gradually contacting the stem of the persimmon. As the cutting mechanism continues to move downwards, the blade cuts the hard stem and thin black edge, completing the removal of the stem and the black edge around its edge; similarly, the second power device outputs a vertical driving force, driving the lower cutting mechanism to move upwards in the vertical direction, and the cutting edge gradually contacts the navel of the persimmon. As the cutting mechanism continues its upward movement, the blades cut through the hard navel and thin black edges, completing the removal of the navel and its surrounding black edge. Once the stem, navel, and upper and lower black edges are removed, the first power unit outputs reverse driving force, causing the upper cutting mechanism and the clamping structure to move vertically upward. The elastic element gradually returns to its natural extended state as the clamping plate moves upward, assisting the clamping structure in quickly resetting until the upper cutting mechanism and clamping structure return to their initial standby position. The second power unit outputs reverse driving force, causing the lower cutting mechanism to move vertically downward, returning to its initial low-position standby position. The conveyor is then started, and the chain plate carries the removed yellow persimmons away from the processing station, transferring them to subsequent cleaning, sorting, or further processing steps. The conveyor continues to run, moving the next set of empty support sections to the processing station. The conveyor stops, and the operator repeats the loading action, allowing the device to enter the next cycle of operation, achieving continuous processing of removing the black edges from yellow persimmons.
