Description

Technical Field

[0001] This invention relates to the field of agricultural equipment technology, and more specifically, to a persimmon peeling machine and its control method. Background Technology

[0002] Persimmon is a deciduous tree belonging to the genus Diospyros in the family Ebenaceae. Its processed product, dried persimmon, is loved by consumers for its unique taste and nutritional value. In the production process of dried persimmon, the main task is to peel the persimmon using a peeling machine. Cutting off the persimmon petals and peeling are key processes that directly affect production efficiency and product quality.

[0003] In the relevant technology, the operator mainly peels the persimmons in the following way: the operator operates the foot pedal to drive the clamping structure to clamp the persimmons; after the persimmons are clamped, the motor is started to drive the persimmons to rotate through the clamping structure. At this time, the operator holds the peeling knife to the rotating persimmons to complete the peeling operation.

[0004] However, in the peeling process described above, operators must use both their feet and hands in close and precise coordination to peel the persimmons effectively. This highly reliance on physical coordination results in low overall efficiency, making it difficult to peel a large number of persimmons in a short time. Moreover, the quality and effect of peeling are highly dependent on the operator's skill level. Especially for novices, due to unfamiliarity with the equipment and poor physical coordination, problems such as incomplete peeling, uneven thickness, and low efficiency are likely to occur. Summary of the Invention

[0005] The problem solved by this invention is that the persimmon peeling machine requires the operator to work with both hands and feet, resulting in low overall efficiency and the peeling quality being highly dependent on the operator's skill level.

[0006] To address the above problems, this invention provides a persimmon peeling machine and its control method.

[0007] In a first aspect, the present invention provides a persimmon peeling machine, comprising a PLC controller, a base, a chassis, a feeding structure, a fork assembly, a peeling assembly, a hook-shaped blade, and a discharging assembly. The chassis is fixedly installed on the base. The feeding structure includes a turntable, small bowls, and a first drive motor. Multiple small bowls are spaced apart circumferentially on the upper part of the turntable, and each small bowl contains a persimmon. The first drive motor is fixedly installed on the base and connected to the turntable to drive it to rotate. The fork assembly is disposed within the chassis and above the rotation path of the small bowls, for inserting into and driving the persimmon to rotate. The hook-shaped blade is disposed on one side of the fork assembly for cutting the petals of the rotating persimmon. The peeling assembly is disposed on one side of the fork assembly for peeling the rotating persimmon. The discharging assembly is disposed on one side of the turntable for unloading the peeled persimmon from the turntable.

[0008] The first drive motor, the fork assembly, the peeling assembly, and the unloading assembly are all electrically connected to the PLC controller.

[0009] Optionally, the feeding structure further includes a first stabilizer structure, which includes multiple positioning claws. The multiple positioning claws are mounted on the turntable around the small bowl and are used to clamp and position the persimmons in the small bowl. Each positioning claw includes a rotating component, and the positioning claw is used to rotate and contact the persimmons through the rotating component.

[0010] Optionally, the positioning claw further includes a first pin, a mounting bracket, a first elastic element, and a first connecting rod. The first pin passes through the mounting bracket and the turntable. The mounting bracket is used to rotate around the axis of the first pin. The first connecting rod passes through the mounting bracket. One end of the first elastic element is fixedly connected to the turntable, and the other end of the first elastic element is connected to the first connecting rod. The rotating element is rotatably mounted on the mounting bracket. The mounting bracket is used to move closer to or further away from the small bowl under the action of the first elastic element, so that the rotating element makes rolling contact with the persimmon inside the small bowl.

[0011] Optionally, the fork assembly includes a lifting assembly, a second drive motor, and a fork structure. The fork structure is used to insert into or release the persimmon in the small bowl. The second drive motor is fixedly connected to the fork structure and is used to drive the fork structure to rotate the persimmon. The lifting assembly is disposed inside the housing and fixedly connected to the second drive motor, and is used to drive the second drive motor to move up and down.

[0012] Optionally, the persimmon peeling machine also includes a cover, which is fixedly installed on the machine base;

[0013] The lifting assembly includes a cylinder, a sliding frame, and a transmission assembly. The second drive motor is fixedly installed on the sliding frame, the cylinder is fixedly installed on the cover, and the piston rod of the cylinder is fixedly connected to the sliding frame for driving the sliding frame to lift. The hook-shaped blade is fixedly connected to the sliding frame.

[0014] The piston rod of cylinder one is also connected to the peeling assembly through the transmission assembly, and is used to drive the peeling assembly and the sliding frame one to move up and down in linkage through the transmission assembly.

[0015] Optionally, the transmission assembly is a pulley assembly;

[0016] And / or, the ratio of the lifting displacement of the fork structure to that of the peeling assembly is 2:1.

[0017] Optionally, the peeling assembly includes a peeling motor, a second sliding frame, and a blade assembly. The peeling motor is connected to the second sliding frame and the blade assembly respectively, and is used to drive the blade assembly to rotate to peel the persimmon.

[0018] The transmission component is connected to the sliding frame.

[0019] Optionally, the knife assembly includes a knife holder, a knife handle, a second cylinder, a knife post, a second elastic element, and a peeling blade. The peeling motor is fixedly connected to the knife holder and is used to drive the knife holder to rotate. One end of the knife handle is hinged to the knife holder. The knife post is fixed to the end of the knife handle away from the knife holder. The peeling blade is fixedly installed on the knife post. The second cylinder is fixedly installed on the knife holder. The piston rod of the second cylinder is fixedly connected to the knife handle and is used to drive the knife handle to rotate relative to the knife holder, so that the peeling blade moves closer to or away from the persimmon.

[0020] The two ends of the second elastic element are respectively connected to the tool holder and the tool base.

[0021] Optionally, the persimmon peeling machine further includes a guiding and shaking structure and a waste discharge port. The guiding and shaking structure includes a first connecting member and a movable baffle. The two ends of the first connecting member are respectively connected to the sliding frame and the movable baffle. The movable baffle is located on one side of the fork structure and is used to receive persimmon peels. The movable baffle is rotatably connected to the cover. The waste discharge port is located below the movable baffle. The first connecting member is used to drive the movable baffle to swing up and down with the lifting and lowering movement of the sliding frame, shaking the persimmon peels on the movable baffle to the waste discharge port.

[0022] Secondly, the present invention provides a control method for a persimmon peeling machine. Based on the persimmon peeling machine described above, the control method for the persimmon peeling machine includes the following steps:

[0023] The turntable controlling the feeding structure rotates intermittently to transfer persimmons;

[0024] When the persimmon is transferred to the peeling station below the fork assembly, the fork assembly is controlled to insert into the persimmon and rotate the persimmon;

[0025] The persimmon petals of the rotating persimmon are cut off by a hook-shaped blade; the peeling assembly is controlled to peel the rotating persimmon.

[0026] After the persimmons have been peeled, the feeding structure is controlled to rotate the persimmons to the unloading position, and the unloading assembly is controlled to unload the peeled persimmons.

[0027] The beneficial effects of the persimmon peeling machine and control method of the present invention are:

[0028] Persimmons can be peeled and have their petals cut in the following way: For example, a loading station is located on the circumference of a turntable, where persimmons can be placed manually into small bowls on the turntable. A PLC controller, electrically connected to a first drive motor, can control the turntable to rotate intermittently, transferring the bowls containing the persimmons to subsequent stations, such as the peeling station. Since the fork assembly is positioned above the rotating path of the bowls, the PLC controller can operate the fork assembly. The fork assembly inserts into the persimmon and drives it to rotate. Simultaneously, the PLC controller controls the peeling assembly, located on one side of the fork assembly, to peel the rotating persimmon. At the same time, a hook-shaped blade on one side of the fork assembly cuts the petals of the rotating persimmon. Subsequently, the first drive motor drives the turntable to rotate the persimmons in the small bowls, after peeling and cutting the persimmon petals, to the next station, such as the unloading station. The peeling component and the unloading component can be controlled by the PLC controller to push the persimmons in the small bowls corresponding to the unloading station off the turntable, thus completing the peeling and petal cutting of one persimmon. During each intermittent rotation of the turntable, a person can continue to place persimmons to be peeled in the empty small bowls on the turntable at the loading station.

[0029] In short, the first drive motor, the fork assembly, the peeling assembly, and the unloading assembly can be coordinated by the PLC controller to effectively realize the transfer, rotation, peeling, petal cutting, and unloading of persimmons. The entire automatic peeling, petal cutting, and unloading operation of persimmons does not require the operator's hand and foot coordination, which can effectively improve the processing efficiency of persimmons. Since the fork assembly, the peeling assembly, and the hook-shaped blade work together to automatically process the persimmons in the small bowl, it does not rely on the operator's skill level, which can improve the processing quality of persimmons.

[0049] To address the problems existing in the aforementioned related technologies, this embodiment provides a persimmon peeling machine and its control method.

[0050] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a persimmon peeling machine, including a PLC controller, a base 1, a chassis 2, a feeding structure 3, a fork assembly 4, a peeling assembly 5, a hook-shaped blade 7, and a unloading assembly 6. The chassis 2 is fixedly installed on the base 1. The feeding structure 3 includes a turntable 31, small bowls 32, and a first drive motor 33. A plurality of small bowls 32 are installed at intervals along the circumference of the turntable 31 on the upper part of the turntable 31. The small bowls 32 are used to hold persimmons. The first drive motor 33 is fixedly installed on the base 1, and the first... A drive motor 33 is connected to the turntable 31 and is used to drive the turntable 31 to rotate; the fork assembly 4 is disposed inside the housing 2 and above the rotation path of the small bowl 32, and is used to insert and drive the persimmon to rotate; the hook-shaped blade 7 is disposed on one side of the fork assembly 4 and is used to cut the persimmon petals of the rotating persimmon; the peeling assembly 5 is disposed on one side of the fork assembly 4 and is used to peel the rotating persimmon; the unloading assembly 6 is disposed on one side of the turntable 31 and is used to unload the peeled persimmons from the turntable 31.

[0051] The first drive motor 33, the fork assembly 4, the peeling assembly 5, and the unloading assembly 6 are all electrically connected to the PLC controller.

[0052] Specifically, the base 1 can be fixedly equipped with an emergency stop button for emergency stop and self-test, a start button for starting the equipment, a power indicator light fixedly installed on the base 1 to indicate whether the equipment is powered on, and a digital tube display screen fixedly installed on the base 1 to display the total number of peels. The emergency stop button and the start button are both electrically connected to the signal input terminal of the PLC controller. The first drive motor 33, the fork assembly 4, the peeling assembly 5, the unloading assembly 6, the power indicator light and the digital tube display screen are all electrically connected to the control terminal of the PLC controller. The PLC controller is an existing structure, and the control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the art, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0053] The first drive motor 33 can be a stepper motor. The first drive motor 33 can be arranged vertically so that the motor shaft of the drive motor faces upward; the motor shaft of the first drive motor 33 can be directly fixedly connected to the turntable 31, or the motor shaft of the first drive motor 33 can be indirectly connected to the turntable 31 through a reduction gear.

[0054] The fixed end of the first drive motor 33, such as the motor housing, can be fixedly connected to the base 1 of the peeling equipment to realize the fixed installation of the first drive motor 33 in the base 1.

[0055] Multiple small bowls 32, spaced circumferentially, can be arranged along the upper edge of the turntable 31. These bowls 32 can be evenly spaced and serve as the feeding positions for persimmons on the turntable 31. Multiple workstations can also be located along the circumference of the turntable 31. The position corresponding to the peeling component 5 can be defined as the peeling workstation, where the fork component 4, hook-shaped blade 7, and peeling component 5 are all located. The position for unloading can be defined as the unloading workstation, where the unloading component 6 is located. Other positions along the circumference of the turntable 31 can be defined as feeding workstations, where workers can place the persimmons to be peeled into the small bowls 32 at the feeding workstations.

[0056] The persimmon flower petals refer to the innermost layer of the flower (inside the calyx). Persimmon flowers typically have four yellowish-white petals that fused together to form a bell-shaped or urn-shaped corolla. The upper part of the corolla is divided into four petal-like lobes. Therefore, strictly speaking, the persimmon flower petals are the upper lobes of the fused corolla. The persimmon flower calyx, on the other hand, refers to the outermost layer of the flower. The persimmon flower calyx also has four green, fleshy lobes that fused at the base to form a cup-shaped or bell-shaped calyx tube with four lobes at the top. Therefore, both the persimmon flower petals and the persimmon flower calyx are considered part of the persimmon flower.

[0057] The machine casing 2 has a feed inlet 21 for persimmons to enter and exit. The turntable 31 extends into the feed inlet 21 of the machine casing 2 so that the turntable 31 can convey the persimmons to the peeling station inside the machine casing 2 when it rotates, so as to peel them.

[0058] Among them, combined Figure 4 and Figure 5 As shown, in order to achieve accurate detection and positioning of the rotation position of the turntable 31, the persimmon peeling machine also includes a detection and positioning component 8. The detection and positioning component 8 includes four magnets 81 fixedly installed on the turntable 31 and located between two adjacent small bowls 32, a first proximity switch 82 fixedly installed on the machine base 1 and located below the turntable 31 on the side closer to the unloading component 6 for contact sensing of the magnets 81, and a first diffuse reflection switch 83 and a second diffuse reflection switch 84 fixedly installed on the machine base 1 and located below the turntable 31 on the side away from the unloading component 6 and below the feed inlet 21 for contact sensing of the magnets 81. The first proximity switch 82, the first diffuse reflection switch 83 and the second diffuse reflection switch 84 are all connected to the input terminal of the PLC controller.

[0059] When the turntable 31 rotates under the drive of the first drive motor 33, rotating the persimmons sequentially to the feed inlet 21 of the machine housing 2, the magnets 81 fixedly installed at different positions on the turntable 31 rotate accordingly. When the four magnets 81 sequentially rotate into the sensing range of the first proximity switch 82, the first diffuse reflection switch 83, or the second diffuse reflection switch 84, the first proximity switch 82, the first diffuse reflection switch 83, or the second diffuse reflection switch 84 will detect the presence of the magnets 81 and generate corresponding sensing signals, which are then transmitted to the PLC controller. Specifically, when the magnets 81 rotate into the sensing range of the first proximity switch 82, the first diffuse reflection switch 83, or the second diffuse reflection switch 84, the first proximity switch 82, the first diffuse reflection switch 83, or the second diffuse reflection switch 84 will detect the presence of the magnets 81 and generate corresponding sensing signals, which will then be transmitted to the PLC controller. When turntable 31 approaches the second diffuse reflection switch 84 or the first diffuse reflection switch 83, both switches transmit signals to the PLC controller. The PLC controller, combining these signals, can accurately determine whether there are persimmons in the small bowl 32 on turntable 31. When the PLC controller receives a signal from the first diffuse reflection switch 83 indicating the presence of persimmons, it controls the first drive motor 33 to rotate turntable 31 90° towards the second diffuse reflection switch 84 and pauses for a set time, allowing the operator to continue rotating towards the first diffuse reflection switch 83 on the next turn. A persimmon is placed in the small bowl 32 at the designated location. When the second diffuse reflection switch 84 sends a feedback signal indicating the presence of a persimmon, the PLC controller will control the first drive motor 33 to rotate the turntable 31 90° towards the feed inlet 21. At this time, the persimmon in the small bowl 32 at the second diffuse reflection switch 84 will automatically rotate to the feed inlet 21. Immediately afterwards, the PLC controller will control the fork assembly 4 to insert the persimmon and rotate it. However, when the operator activates the emergency stop button, the PLC controller can activate the emergency stop via one of the magnets 81 and the first proximity switch. Feedback from the sensing signal generated by 82 determines whether the four small bowls 32 on the turntable 31 are respectively located at the feed inlet 21, the unloading component 6, the first diffuse reflection switch 83, and the second diffuse reflection switch 84. If no feedback is received, the PLC controller will drive the turntable 31 to rotate via the first drive motor 33 until feedback from the sensing signal generated by one of the magnets 81 and the first proximity switch 82 is received. This ensures that the four small bowls 32 on the turntable 31 are rotated to the correct position so that the operator can start the equipment to perform operations such as feeding and peeling persimmons.

[0060] The persimmon peeling machine of this application is not limited to cutting persimmons, but can also be used to cut other fruits that are similar in shape to persimmons and need to be peeled, such as apples and pears.

[0061] In this embodiment, the persimmon can be peeled and its petals cut off in the following way: for example, the turntable 31 has a loading station for placing persimmons on its circumference. The persimmons to be peeled can be placed manually into the small bowls 32 on the turntable 31. The turntable 31 can be driven intermittently by the PLC controller connected to the first drive motor 33 to control the first drive motor 33 to drive the turntable 31 to rotate intermittently, so as to transfer the small bowls 32 containing the persimmons to the subsequent station, such as the peeling station. Since the fork assembly 4 is positioned above the rotation path of the small bowl 32, when a persimmon in a small bowl 32 rotates to below the fork assembly 4, the turntable 31 stops rotating. The fork assembly 4 can be controlled by the PLC controller to operate, inserting the persimmon into the fork assembly 4 and driving the persimmon to rotate. At this time, the peeling assembly 5 can be controlled by the PLC controller to operate, peeling the rotating persimmon with the peeling assembly 5 located on one side of the fork assembly 4. At the same time, the hook-shaped blade 7 located on one side of the fork assembly 4 can cut the petals of the rotating persimmon. Subsequently, the first drive motor 33 drives the turntable 31 to rotate the persimmons in the small bowl 32 after peeling and cutting the persimmon petals to the next station, such as the unloading station. The unloading component 6 can be controlled by the PLC controller to push the persimmons in the small bowl 32 corresponding to the unloading station out of the turntable 31, thus completing the entire process of peeling and cutting the persimmon petals of one persimmon. During each intermittent rotation of the turntable 31, the operator can continue to place persimmons to be peeled in the empty small bowl 32 on the turntable 31 at the loading station.

[0062] In short, the first drive motor 33, the fork assembly 4, the peeling assembly 5, and the unloading assembly 6 can be coordinated by the PLC controller to effectively realize the transfer, rotation, peeling, petal cutting, and unloading of persimmons. The entire automatic peeling, petal cutting, and unloading of persimmons does not require the operator's hand and foot coordination, which can effectively improve the processing efficiency of persimmons. Since the fork assembly 4, the peeling assembly 5, and the hook-shaped blade 7 work together to automatically process the persimmons in the small bowl 32, they do not rely on the operator's skill level, which can improve the processing quality of persimmons.

[0063] Optionally, combined Figure 5 As shown, the feeding structure 3 also includes a first stabilizer structure 34, which includes a plurality of positioning claws 341. The plurality of positioning claws 341 are mounted on the turntable 31 around the small bowl 32 and are used to clamp and position the persimmons in the small bowl 32. Each positioning claw 341 includes a rotating member 3416, and the positioning claw 341 is used to rotate and contact the persimmons through the rotating member 3416.

[0064] Specifically, a first stabilizer structure 34 can be set on the turntable 31 circumferentially with each small bowl 32.

[0065] Each first stabilizer structure 34 may include multiple positioning claws 341, such as three positioning claws 341 (see...). Figure 5 (as shown), or four positioning claws 341.

[0066] In this optional embodiment, since a first stabilizer structure 34 is arranged circumferentially around each small bowl 32 on the turntable 31, and multiple positioning claws 341 of the first stabilizer structure 34 are arranged around the outer periphery of the small bowl 32, when a persimmon is placed in the small bowl 32, the persimmon can be clamped and positioned by the multiple positioning claws 341 to prevent the persimmon from falling out of the small bowl 32 during the intermittent rotation of the turntable 31. Since the positioning claws 341 are used to make rotational contact with the persimmon through the rotating member 3416, the rotational contact between the rotating member 3416 and the persimmon, while achieving clamping and positioning of the persimmon, can help the fork assembly 4 rotate the persimmon.

[0067] Optionally, combined Figure 6 As shown, the positioning claw 341 further includes a first pin 3411, a mounting bracket 3412, a first elastic element 3413, and a first connecting rod 3414. The first pin 3411 passes through the mounting bracket 3412 and the turntable 31. The mounting bracket 3412 is used to rotate around the axis of the first pin 3411. The first connecting rod 3414 passes through the mounting bracket 3412. One end of the first elastic element 3413 is fixedly connected to the turntable 31, and the other end of the first elastic element 3413 is connected to the first connecting rod 3414. The rotating element 3416 is rotatably mounted on the mounting bracket 3412. The mounting bracket 3412 is used to move closer to or further away from the small bowl 32 under the action of the first elastic element 3413, so that the rotating element 3416 rolls into contact with the persimmon inside the small bowl 32.

[0068] Specifically, the first pin 3411 is movably inserted through the mounting bracket 3412 and the turntable 31, so that the mounting bracket 3412 can rotate around the first pin 3411. The first connecting rod 3414 is inserted through the mounting bracket 3412, and both the first connecting rod 3414 and the first pin 3411 are arranged vertically and parallel to each other.

[0069] The first elastic element 3413 may be a tension spring or an elastic tension rope; one end of the first elastic element 3413 may be directly or through other components fixedly connected to the turntable 31, and the other end of the first elastic element 3413 may be connected to the first connecting rod 3414.

[0070] During the clamping process of the persimmon, the rotating part 3416 installed on the mounting frame 3412 can rotate and contact the persimmon.

[0071] In this optional embodiment, the first elastic element 3413 is used to pull the mounting bracket 3412 around the first pin 3411 by its own elastic tension, so as to approach the persimmon and make rotational contact with the persimmon through the rotating element 3416, thereby clamping and positioning the persimmon in the small bowl 32. Specifically, when no persimmon is placed in the small bowl 32, the first elastic element 3413 is in its initial state, that is, the first elastic element 3413 is in a contracted state, and the rotating element 3416 provided on the mounting bracket 3412 is located in the upper region of the small bowl 32. Since the diameter of the persimmon gradually increases from the bottom to the middle, that is, the lower surface of the persimmon is an inclined arc surface, when the persimmon is placed in the small bowl 32 from top to bottom, the inclined arc surface of the lower part of the persimmon applies a pushing force towards the outside of the small bowl 32 to the rotating element 3416 located above the small bowl 32. The rotating element 3416 and the mounting bracket 3412 will drive the first connecting rod 34 14 rotates around the first pin 3411. In other words, the multiple positioning claws 341 of the first stabilizer structure 34 rotate simultaneously away from the small bowl 32 to open. At the same time, the first connecting rod 3414 pulls the first elastic element 3413 during the rotation of the mounting frame 3412, causing the first elastic element 3413 to be stretched. After the persimmon is completely placed in the small bowl 32, the elastic pulling force of the first elastic element 3413 of the multiple positioning claws 341 in the first stabilizer structure 34 can be used to apply a clamping force to the persimmon in the small bowl 32. Compared with the related technology, which clamps the persimmon by relatively set telescopic cylinders, which increases energy consumption and damages the persimmon, this embodiment can use the elastic force of the first elastic element 3413 in the positioning claw 341 to clamp, thereby achieving the positioning and clamping operation of the persimmon, not only reducing cost and energy consumption, but also avoiding damage to the persimmon.

[0072] Optionally, the end of the first elastic element 3413 away from the first connecting rod 3414 can be fixedly connected to the turntable 31 in the following manner, for example, by combining... Figure 6 As shown, the first stabilizer structure 34 further includes a second connecting rod 342, which is fixedly connected to the turntable 31 and is located on one side of the mounting bracket 3412. The end of the first elastic member 3413 away from the first connecting rod 3414 is connected to the second connecting rod 342 or the first pin 3411 of the other positioning claw 341.

[0073] Specifically, the second connecting rod 342 can be fixedly installed on the turntable 31 and is located on one side of the mounting bracket 3412.

[0074] If the number of positioning claws 341 in the first stabilizer structure 34 is odd, such as three, a second connecting rod 342 can be provided on one side of the mounting bracket 3412 of one of the positioning claws 341. In this case, the second connecting rod 342 provided on one side of the mounting bracket 3412 can be used to connect the end of the first elastic member 3413 away from the first connecting rod 3414. See Figure 5 As shown, in other words, in the first stabilizer structure 34, there are three positioning claws 341. In the structure of one positioning claw 341, the two ends of the first elastic element 3413 are respectively connected to the second connecting rod 342 and the first connecting rod 3414. In the other two positioning claws 341, one end of the first elastic element 3413 of one positioning claw 341 is connected to the first connecting rod 3414, and the other end of the first elastic element 3413 of one positioning claw 341 can be connected to the first pin 3411 of the adjacent positioning claw 341.

[0075] If the number of positioning claws 341 in the first stabilizer structure 34 is even, such as four, then the first stabilizer structure 34 may not include the second connecting rod 342. In this case, one end of the first elastic element 3413 in each positioning claw 341 is connected to the first connecting rod 3414, and the other end of the first elastic element 3413 in each positioning claw 341 is connected to the first pin 3411 of the adjacent positioning claw 341.

[0076] The end of the first elastic member 3413 can be connected to the first connecting rod 3414, the second connecting rod 342, or the first pin 3411 by hooking.

[0077] Furthermore, slots can be provided in the first connecting rod 3414, the second connecting rod 342, and the first pin 3411, and the end of the first elastic member 3413 can be placed in the slot to prevent the first elastic member 3413 from moving up and down during the stretching deformation process, so as to ensure the stability of each positioning claw 341 when it rotates open or closes.

[0078] In this optional embodiment, when the first stabilizer structure 34 includes three positioning claws 341, the end of the first elastic element 3413 of one of the positioning claws 341 that is away from the first connecting rod 3414 can be connected to the second connecting rod 342. Thus, the structure of the positioning claws 341 can be simplified while achieving the positioning of the persimmon using the three positioning claws 341, making it simple and convenient.

[0079] The unloading assembly 6 includes a through hole 61 on the turntable 31 located below the small bowl 32 and communicating with the small bowl 32, a cylinder 62 fixedly mounted on the base 1, and an inclined groove 63 fixedly mounted on the base 1 for discharging persimmons.

[0080] The PLC controller is also electrically connected to cylinder 362. Through holes 61 are made on the turntable 31 at the corresponding positions of each small bowl 32.

[0081] After the persimmons have been peeled, the PLC controller, according to the preset program, determines that the small bowl 32 on the turntable 31 near the first proximity switch 82 contains peeled persimmons and has reached the unloading position. It then sends a start signal to cylinder 62. After receiving the signal, cylinder 62 starts working. The piston rod of cylinder 62 extends upward and passes through the through hole 61 of the turntable 31. By contacting the persimmons in the small bowl 32 and applying an upward thrust, the persimmons in the small bowl 32 are pushed out of the through hole 61 and slide down the inclined groove 63, thus completing the unloading action and ensuring the continuity of the peeling equipment's workflow.

[0082] Optionally, combined Figure 7 and Figure 8 As shown, the fork assembly 4 includes a lifting assembly 43, a second drive motor 42, and a fork structure 41. The fork structure 41 is used to insert into or detach from the persimmon in the small bowl 32. The second drive motor 42 is fixedly connected to the fork structure 41 and is used to drive the fork structure 41 to rotate the persimmon. The lifting assembly 43 is disposed in the housing 2 and fixedly connected to the second drive motor 42 and is used to drive the second drive motor 42 to move up and down.

[0083] Specifically, the lifting assembly 43 can be directly or fixedly mounted on the base 1 through other structures such as the cover 431.

[0084] The lifting assembly 43 is used to drive the second drive motor 42 to move up and down, so as to raise the fork structure 41 away from the persimmon or lower it to insert into the persimmon's stem position.

[0085] In this optional embodiment, the PLC controller first determines that the persimmon in the small bowl 32 at the feed inlet 21 is in place based on the position signal of the turntable 31 fed back by the detection and positioning component 8. When one of the persimmons in the small bowl 32 rotates to the position of the feed inlet 21, the PLC controller sends a start signal to the lifting component 43. At this time, the lifting component 43 drives the second drive motor 42 to drive the fork structure 41 to descend until the fork structure 41 accurately inserts the persimmon. Then, the PLC controller sends a start signal to the second drive motor 42, and the second drive motor 42 starts to run, driving the fork structure 41 to rotate the persimmon, thereby preparing for the peeling component 5 to peel the rotating persimmon.

[0086] Optionally, combined Figure 7 and Figure 8 As shown, the persimmon peeling machine also includes a cover 431, which is fixedly installed on the machine base 1;

[0087] The lifting assembly 43 includes a cylinder 433, a sliding frame 432, and a transmission assembly 434. The second drive motor 42 is fixedly installed on the sliding frame 432, the cylinder 433 is fixedly installed on the cover 431, and the piston rod of the cylinder 433 is fixedly connected to the sliding frame 432 for driving the sliding frame 432 to lift. The hook-shaped blade 7 is fixedly connected to the sliding frame 432.

[0088] The piston rod of the cylinder 433 is also connected to the peeling assembly 5 through the transmission assembly 434, so as to drive the peeling assembly 5 and the sliding frame 432 to move up and down in linkage through the transmission assembly 434.

[0089] Specifically, the cover 431 can be fixed to the base 1 by means of bolts, fasteners, or welding.

[0090] The sliding frame 432 and the cover 431 can be slidably connected in the following manner, for example, by combining Figure 3 As shown, the sliding frame 432 can be slidably connected to the cover 431 via a sliding rail structure, thereby ensuring the stability of the vertical lifting and lowering movement of the sliding frame 432 relative to the cover 431. The fork structure 41 can be a fork with a cylindrical upper part and a multi-clawed lower part, such as a three-clawed fork.

[0091] Cylinder 433 can be a telescopic cylinder component.

[0092] Combination Figure 9 As shown, the hook-shaped blade 7 can be directly or indirectly fixedly connected to the sliding frame 432 via a connecting rod, and the hook-shaped blade 7 is located on the periphery of the fork structure 41. The hook-shaped blade 7 is used to cut the persimmon petals. In this application, the hook-shaped blade 7 can be used to both cut the persimmon petals and remove the persimmon stem.

[0093] The hook-shaped blade 7 can move up and down with the sliding frame 432 under the drive of the cylinder 433. The hook-shaped blade 7 moves up and down with the fork structure 41 and descends to the periphery of the persimmon's flower stem. Since the second drive motor 42 drives the persimmon to rotate through the fork structure 41, the persimmon can rotate relative to the hook-shaped blade 7 fixed on the sliding frame 432. The fixed hook-shaped blade 7 can cut the petals of the persimmon that has rotated at least once.

[0094] In this optional embodiment, the PLC controller first determines that the persimmons in the small bowls 32 at the feed inlet 21 are in place based on the position signal of the turntable 31 fed back by the detection and positioning component 8. When one of the persimmons in the small bowls 32 rotates to the position of the feed inlet 21, the PLC controller sends a start signal to the cylinder 433 of the lifting component 43. At this time, the cylinder 433 starts working after receiving the signal and drives the sliding frame 432 to slide downward relative to the cover 431. Since the second drive motor 42 is fixedly installed on the sliding frame 432, the second drive motor 42 will slide downward with the sliding frame 432. The cylinder 42 descends, causing the fork structure 41, fixed on the output shaft of the second drive motor 42, to move downwards until the fork structure 41 accurately inserts into the persimmon in the small bowl. Immediately afterwards, the PLC controller sends a start signal to the second drive motor 42, and the second drive motor 42 starts to run, driving the fork structure 41 to rotate, thereby causing the persimmon to rotate. During the process of the fork structure 41 descending to insert into the persimmon, since the piston rod of cylinder 433 is connected to the peeling assembly 5 through the transmission assembly 434, the peeling assembly 5 can descend synchronously with the sliding frame 432, preparing for the subsequent peeling action.

[0095] The persimmons can be peeled in the following way: For example, the feeding structure 3 transfers the persimmons to be peeled to the area below the fork structure 41. Since the second drive motor 42, which is fixed on the sliding frame 432, is connected to the fork structure 41, and the piston rod of the cylinder 433 is fixedly connected to the sliding frame 432, the cylinder 433 can drive the sliding frame 432 to drive the second drive motor 42 and the fork structure 41 to descend synchronously until the fork structure 41 descends to the persimmon's stem position. Since the piston rod of the cylinder 433 is also connected to the transmission assembly... 434 is fixedly connected to the peeling component 5 so that the peeling component 5 and the sliding frame 432 can be linked and lifted and lowered through the transmission component 434. However, the lifting and lowering speeds of the two can be different. In other words, under the drive of the cylinder 433, the peeling component 5 and the fork structure 41 can descend synchronously. When the fork structure 41 descends to insert into the persimmon, the peeling component 5 can descend to one side of the persimmon, and the axis of the peeling motor 57 of the peeling component 5 can be roughly aligned with the center of the persimmon, thereby achieving synchronous positioning of the peeling component 5 and the fork structure 41 relative to the persimmon.

[0096] Optionally, combined Figure 7 and Figure 8 As shown, the transmission component 434 is a pulley assembly;

[0097] And / or, the ratio of the lifting displacement of the fork structure 41 to that of the peeling assembly 5 is 2:1.

[0098] Specifically, the transmission component 434 can be a pulley assembly, which, compared to other transmission methods such as gears and racks, is not only easier to install, but also improves the smoothness of the lifting and lowering movement of the peeling component 5.

[0099] Since the fork motor fixed on the sliding frame 432 is connected to the fork structure 41, the sliding frame 432 and the fork structure 41 can move up and down synchronously. The transmission component 434 can be fixedly connected to the peeling component 5 so that the transmission component 434 can drive the entire peeling component 5 to move up and down.

[0100] The transmission assembly 434 can adopt the following structure, combined with Figure 7 and Figure 8 As shown, for example, the transmission assembly 434 includes a guide wheel 4341, a guide wheel 4342, a guide wheel 4343, and a wire rope 4344. The persimmon peeling machine also includes a mounting base 1, a first fastener, a second fastener, and a mounting base 2. The mounting base 1 can be fixed to the inner wall of the machine housing 2 by bolts. The first fastener passes through the guide wheel 4341, the mounting base 1, and the machine housing 2 to mount the guide wheel 4341 to the inner wall of the machine housing 2 via the mounting base 1. The guide wheel 4341 can rotate around the first fastener. The guide wheel 4341 can be positioned away from the sliding frame 4343 by the cylinder 433. On one side of 32; similarly, mounting base two can be fixed to the inner wall of chassis 2 by bolts, and the second fastener passes through guide wheel two 4342, mounting base two and chassis 2 to install guide wheel two 4342 on the inner wall of chassis 2, and guide wheel two 4342 can rotate around the second fastener. Guide wheel two 4342 can be located on the side of guide wheel one 4341 away from sliding frame one 432, and the height of guide wheel two 4342 can be higher than that of guide wheel one 4341, which can ensure that the peeling component 5 has a certain drag height. Guide wheel one 4341 and guide wheel two 4342 can both be fixed pulley structures.

[0101] Guide wheel 3 4343 is a movable pulley. Guide wheel 3 4343 is connected to peeling component 5 and is used to drive peeling component 5 to move up and down synchronously.

[0102] Both ends of the wire rope 4344 can be connected to the sliding frame 432 and the housing 2 by means of hooks or rings, which can improve the convenience of connecting the wire rope 4344 to the sliding frame 432 and the housing 2.

[0103] In this optional embodiment, before peeling the persimmon, cylinder 433 drives sliding frame 432 to move the fork structure 41 downwards and closer to the persimmon's stem. One end of the steel wire rope 4344 in transmission assembly 434 is fixedly connected to sliding frame 432, and the guide wheel 4343 of transmission assembly 434 is fixedly connected to peeling assembly 5. This allows the transmission assembly 434 to simultaneously drive the peeling assembly 5 downwards while cylinder 433 drives the fork structure 41 downwards and inserts it into the persimmon's stem. The peeling component 5 moves synchronously closer to the persimmon; and during this process, the ratio of the vertical displacement (i.e., the displacement in the height direction) of the fork structure 41 moving downward from the highest point to insert into the persimmon's stem position to the vertical displacement (i.e., the displacement in the height direction) of the peeling component 5 moving from the highest point to the lowest point is 2:1. This ensures that when the fork structure 41 inserts into the persimmon, the output shaft of the peeling motor 57 is approximately at the same height as the center of the persimmon. In other words, the shaft height of the peeling motor 57 is aligned with the center of the persimmon, making it suitable for persimmons of different sizes.

[0104] Optionally, combined Figure 7 and Figure 8 As shown, the peeling assembly 5 includes a peeling motor 57, a sliding frame 51, and a blade assembly. The peeling motor 57 is connected to the sliding frame 51 and the blade assembly respectively, and is used to drive the blade assembly to rotate to peel the persimmon.

[0105] The transmission assembly 434 is connected to the sliding frame 51.

[0106] Specifically, the guide wheel 4343 of the transmission assembly 434 can be fixedly connected to the sliding frame 51, in combination with... Figure 8 As shown in the figure; or, the guide wheel 3 4343 can also be directly fixedly connected to the peeling motor 57 (not shown in the figure).

[0107] In this optional embodiment, during the peeling operation, the second drive motor 42 drives the fork structure 41 to rotate, thereby rotating the persimmon. The peeling motor 57 drives the blade assembly to rotate, and the axis of the peeling motor 57 can be roughly aligned with the center of the persimmon, so that the blade assembly can peel the rotating persimmon completely from the top and bottom of the persimmon in a rotating manner. In short, before peeling the persimmon, the blade assembly of the peeling component 5 moves closer to the persimmon synchronously as the fork structure 41 is inserted into the persimmon's stem, thereby achieving synchronous positioning of the blade assembly and the fork structure 41, so that the axis of the peeling motor 57 is roughly aligned with the center of the persimmon, ensuring that the rotation center of the persimmon matches the feed trajectory of the blade assembly, and correspondingly achieving uniform cutting thickness of the persimmon, thereby improving the peeling effect of the persimmon; in addition, it is also beneficial to improve the versatility of the persimmon peeling machine for peeling persimmons of different sizes.

[0108] Optionally, combined Figure 10 As shown, the knife assembly includes a knife holder 52, a knife handle 53, a second cylinder 56, a knife post 54, a second elastic element 58, and a peeling blade 55. The peeling motor 57 is fixedly connected to the knife holder 52 and is used to drive the knife holder 52 to rotate. One end of the knife handle 53 is hinged to the knife holder 52. The knife post 54 is fixed to the end of the knife handle 53 away from the knife holder 52. The peeling blade 55 is fixedly installed on the knife post 54. The second cylinder 56 is fixedly installed on the knife holder 52. The piston rod of the second cylinder 56 is fixedly connected to the knife handle 53 and is used to drive the knife handle 53 to rotate relative to the knife holder 52, so that the peeling blade 55 moves closer to or away from the persimmon.

[0109] The two ends of the second elastic member 58 are respectively connected to the handle 53 and the tool holder 52.

[0110] Specifically, the motor shaft of the peeling motor 57 passes through the guide hole of the cover 431 and can be fixedly connected to the tool holder 52 via a coupling, so that the tool holder 52 can rotate synchronously with the motor shaft of the peeling motor 57. One end of the tool holder 53 can be hinged to the tool holder 52 via a rotating component 3416, such as a hinge or pin structure, so that the tool holder 53 can rotate relative to the tool holder 52. The tool post 54 can be fixedly connected to the tool holder 53 by fasteners or welding, so that the tool post 54 is fixedly mounted on the tool holder 53.

[0111] Cylinder 2 56 can be fixedly installed in the knife holder 52 by means of bolt fasteners or welding, and the end of the piston rod of cylinder 2 56 is fixedly connected to the knife handle 53 to drive the knife handle 53 to rotate relative to the knife holder 52, so that the knife handle 53 drives the peeling blade 55 to move closer to or away from the persimmon.

[0112] The peeler blade 55 can be fixedly installed on the blade holder 54 by means of snap-fit, plug-in, bolt, etc., so the blade holder 54 can be used as the mounting base for the peeler blade 55.

[0113] The peeling blade 55 can be a utility knife blade or other types of blades. Any blade that can cut the persimmon peel is suitable for this technical solution, and no specific limitation is made here.

[0114] The second elastic element 58 is an elastic structure that is in a contracted state when not under tension and in an extended state when under tension. For example, the second elastic element 58 can be a tension elastic rope or a tension spring.

[0115] A hole structure or a hook structure can be provided on the tool holder 52, and a hole structure or a hook structure can also be provided on the tool shank 53, so as to facilitate the quick connection of the two ends of the second elastic member 58 to the tool holder 52 and the tool shank 53 respectively.

[0116] The handle 53 may be plate-shaped and may have certain deformation properties. For example, it may undergo slight deformation under the tension of the second elastic element 58 so that the peeling blade 55 can better approach persimmons of different sizes.

[0117] In this optional embodiment, when the transmission assembly 434 drives the sliding frame 2 51 to rise and fall synchronously with the cover 431 and the sliding frame 1 432, so that the peeling blade 55 reaches a suitable height, for example, a control signal can be sent to the cylinder 2 56 through the PLC controller. The piston rod of the cylinder 2 56 retracts to drive the handle 53 to rotate around the hinge point of the blade holder 52, so that the peeling blade 55 is closer to the persimmon. The contraction and tension of the second elastic element 58 can make the peeling blade 55 even closer to the persimmon to ensure the peeling effect. After adjusting the contact distance between the peeling blade 55 and the persimmon, the PLC controller synchronously sends a start and speed control signal to the peeling motor 57. At this time, the peeling motor 57 drives the blade holder 52 to rotate, driving the handle 53 and the blade holder 52 to rotate. 4. The peeling blade 55 rotates around the persimmon, causing it to rotate from the top to the bottom tip for peeling. During this peeling process, the rotation axis of the blade holder 54 always points to the center of the persimmon, ensuring effective peeling. After peeling, the PLC controller sends a control signal to the cylinder 56 again, causing the piston rod of the cylinder 56 to extend and drive the handle 53 to rotate around the hinge point of the blade holder 52, causing the peeling blade 55 to leave the persimmon. At this time, the second elastic element 58 is stretched. Simultaneously, the PLC controller sends a control signal to the peeling motor 57 again, causing the peeling motor 57 to drive the blade holder 52, handle 53, blade holder 54, and peeling blade 55 to rotate to the initial position (i.e., the high position), preparing for the next peeling.

[0118] Optionally, combined Figures 11 to 13 As shown, the persimmon peeling machine also includes a guide and shaking structure 100 and a waste discharge port 22. The guide and shaking structure 100 includes a first connecting member 111 and a movable baffle 121. The two ends of the first connecting member 111 are respectively connected to the sliding frame 432 and the movable baffle 121. The movable baffle 121 is located on one side of the fork structure 41 and is used to receive persimmon peels. The movable baffle 121 is rotatably connected to the cover 431. The waste discharge port 22 is located below the movable baffle 121. The first connecting member 111 is used to drive the movable baffle 121 to swing up and down with the lifting and lowering movement of the sliding frame 432, shaking the persimmon peels on the movable baffle 121 to the waste discharge port 22.

[0119] Specifically, the first connector 111 can serve as an intermediate connecting component between the movable baffle 121 and the sliding frame 432 in the fork assembly 4. For example, the upper end of the first connector 111 can be connected to the sliding frame 432, and the lower end of the first connector 111 can be movably connected to the movable baffle 121. The first connector 111 can move up and down synchronously with the sliding frame 432. One end of the movable baffle 121 can be rotatably connected to the inner wall of the cover 431 through a rotating component 3416, such as a hinge or pin structure.

[0120] The first connecting member 111 includes a connecting rod, a roller structure, and a rod-shaped connector. One end of the connecting rod is used to connect with the sliding frame 432. The roller structure is connected to the end of the connecting rod away from the sliding frame 432 through the rod-shaped connector. The roller structure makes rolling contact with the movable baffle 121. The end of the connecting rod away from the sliding frame 432 vertically passes through the through hole 1210 of the movable baffle 121.

[0121] An inclined waste discharge port 22 can be installed on the rear side of the feeding structure 3. The waste discharge port 22 can be a chute plate structure. A movable baffle 121 is provided at the upper end of the waste discharge port 22, and a second collection box (not shown in the figure) can be provided at the lower end of the waste discharge port 22 so that the persimmon peels shaken off from the movable baffle 121 slide down the waste discharge port 22 into the second collection box. Therefore, the second collection box can be used to collect the persimmon peels peeled off the persimmons.

[0122] The guide shaking structure 100 also includes a shovel plate 131. One end of the shovel plate 131 is rotatably connected to the cover 431, and the other end of the shovel plate 131 is located on the movable baffle 121. The shovel plate 131 is used to rotate as the movable baffle 121 swings up and down.

[0123] In this optional embodiment, the peeling component 5 can be used to peel the persimmon while it is rotating.

[0124] Due to the inertia generated by the high-speed rotation of the persimmon, the cut persimmon peel tends to continue rotating with the persimmon. The movable baffle 121 is set on one side of the fork assembly 4 to prevent the persimmon peel from continuing to rotate, thus preventing the persimmon peel from falling onto the turntable 31 of the feeding structure 3 and ensuring that the upper surface of the turntable 31 is clean. One end of the movable baffle 121 is rotatably connected to the cover 431 of the peeling equipment, so that the movable baffle 121 is rotatably installed inside the cover 431. Since the two ends of the first connecting member 111 of the guide shaking structure 100 are respectively connected to the sliding frame 432 and the movable baffle 121, the movable baffle 121 forms a linkage mechanism with the sliding frame 432 through the first connecting member 111. The first connecting member 111 can drive the movable baffle 121 to swing up and down with the lifting and lowering movement of the sliding frame 432, so that the persimmon peel is intermittently and quickly shaken off and discharged to the waste outlet 22 on the side (e.g., the rear side) of the feeding structure 3 through the movable baffle 121 with the changing tilt angle, so as to avoid the persimmon peel falling directly onto the turntable 31, and thus ensure the peeling effect of the persimmon.

[0125] Because persimmon peels have a certain stickiness, some persimmon peels may not be able to be shaken off smoothly to the waste outlet 22. Therefore, in this embodiment, a shovel plate 131 is provided. When the first connecting member 111 moves upward with the sliding frame 432, the first connecting member 111 can pull the movable baffle 121 to swing upward. The upward swing of the movable baffle 121 will lift the shovel plate 131, causing the shovel plate 131 to swing upward as well. During this process, the shovel plate 131 will have a shoveling action on the persimmon peels on the movable baffle 121. This process is continuously repeated to quickly shake off and shovel out all the persimmon peels on the movable baffle 121, effectively preventing the persimmon peels from being stuck on the movable baffle 121, and achieving the effect of shaking off and cleaning the persimmon peels on the movable baffle 121.

[0126] This invention provides a control method for a persimmon peeling machine. Based on the persimmon peeling machine described in the above embodiment, the control method includes the following steps:

[0127] The turntable 31 of the feeding structure 3 is controlled to rotate intermittently to transfer persimmons; for example, the first drive motor 33 can be controlled by a PLC controller to drive the turntable to rotate intermittently so as to transfer the persimmons to each workstation.

[0128] When the persimmon is transferred to the peeling station below the fork assembly 4, the fork assembly 4 is controlled to insert into the persimmon and rotate the persimmon;

[0129] The hook-shaped blade 7 cuts the persimmon petals of the rotating persimmon; the peeling assembly 5 is controlled to peel the rotating persimmon.

[0130] After the persimmons have been peeled, the feeding structure 3 is controlled to rotate the persimmons to the unloading position, and the unloading assembly 6 is controlled to unload the peeled persimmons.
