Description

Technical Field

[0001] This utility model relates to the field of agricultural product technology, and more specifically, to a persimmon peeling machine. Background Technology

[0002] Persimmon is a deciduous tree belonging to the genus Diospyros in the family Ebenaceae. Its processed product, dried persimmon, is highly favored by consumers for its unique taste and nutritional value. Peeling is a crucial step in the production of dried persimmon, directly impacting production efficiency and product quality. Traditional manual peeling methods suffer from low efficiency, high labor intensity, and uneven peel thickness, making them unsuitable for large-scale production.

[0003] In related technologies, persimmon peeling machines are commonly used to peel persimmons. For example, a persimmon peeling machine mainly includes a feeding structure, a fork assembly, and a peeling assembly. The feeding structure has a feeding position for placing persimmons to be peeled. The fork assembly can be inserted into the flower stem position of the persimmon and is used to drive the persimmons on the feeding position to rotate. The peeling assembly mainly includes a rotary motor and a blade assembly. The rotary motor drives the blade assembly to rotate so that the blade assembly can peel the persimmons in the rotating state.

[0004] However, due to the dynamic operational deviation between the fork assembly and the peeling assembly, their coordination becomes inaccurate, resulting in a misalignment between the persimmon's rotation center and the feed trajectory of the blade assembly. This causes uneven cutting thickness of the persimmon, increases the persimmon pulp loss rate, and affects the peeling effect of the persimmon. Utility Model Content

[0005] The problem this invention solves is how to improve the peeling effect of persimmons using a persimmon peeling machine.

[0006] To solve the above problems, this utility model provides a persimmon peeling machine, including a cover, a cylinder, a fork assembly, a transmission assembly, and a peeling assembly.

[0009] Optionally, the persimmon peeling machine further includes a housing, which is fitted over the cover. The transmission assembly includes a guide wheel one, a guide wheel two, a guide wheel three, and a wire rope. The guide wheel one is rotatably disposed inside the housing and corresponds to one side of the sliding frame one. The guide wheel two is rotatably connected inside the housing to the side of the guide wheel one away from the sliding frame one, and the guide wheel two is positioned above the guide wheel one. The guide wheel three is rotatably disposed to the side of the guide wheel two away from the guide wheel one. The guide wheel three is fixedly connected to the peeling motor or the sliding frame two. The two ends of the wire rope are respectively fixedly connected to the sliding frame one and the housing, and the wire rope is sequentially wound around the guide wheel one, the guide wheel two, and the guide wheel three.

[0010] Optionally, the cover is provided with a guide hole, the motor shaft of the peeling motor passes through the guide hole and is fixedly connected to the knife holder assembly, and the motor shaft of the peeling motor is used to move up and down along the guide hole.

[0011] Optionally, the knife assembly includes a knife holder, a knife handle, a second cylinder, a knife post, 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, so that the peeling blade moves closer to or away from the persimmon.

[0012] Optionally, the tool holder assembly further includes an elastic element, the two ends of which are respectively connected to the tool shank and the tool holder.

[0013] Optionally, the knife handle is provided with a plurality of connecting holes arranged at intervals, the arrangement direction of the plurality of connecting holes being parallel to the extension direction of the knife handle, and one end of the elastic member being detachably connected to one of the connecting holes.

[0014] Optionally, the persimmon peeling machine also includes a detection and positioning component two, which includes a second proximity switch and an ear piece. The second proximity switch is fixedly mounted on the sliding frame two, and the ear piece is fixedly mounted on the blade assembly for sensing contact with the second proximity switch.

[0015] Optionally, the peeling assembly further includes a first sliding member and a second sliding member, the first sliding member being fixedly connected to the sliding frame, the second sliding member being fixedly connected to the inner wall of the chassis, and the first sliding member and the second sliding member being slidably connected in a vertical direction.

[0016] Optionally, the persimmon peeling machine also includes a base and a feeding structure, the feeding structure being mounted on the base and used to transfer persimmons.

[0017] The beneficial effects of this persimmon peeling machine are:

[0018] The persimmon peeling machine may include a feeding structure and a base for feeding materials, wherein the feeding structure may be mounted on the base; the persimmon peeling machine may include a fork assembly, a cover, a transmission assembly, a peeling assembly and a cylinder fixed to the cover, the cover may be fixedly mounted on the base, and the fork assembly and the transmission assembly are both located above the feeding structure.

[0019] The peeling motor is fixedly connected to the sliding frame 2, therefore, the sliding frame 2 provides an installation base for the peeling motor.

[0020] The persimmon can be peeled in the following way: For example, the feeding structure transfers the persimmon to be peeled to the area below the fork assembly. Since the fork motor fixed to the sliding frame is connected to the fork structure, and the piston rod of the cylinder is fixedly connected to the sliding frame, the cylinder can drive the sliding frame to move the fork motor and the fork structure down synchronously until the fork structure descends to the persimmon's stem position. Since the piston rod of the cylinder is also fixedly connected to the peeling assembly through the transmission assembly, the transmission assembly can drive the peeling assembly and the sliding frame to lift and lower in linkage, but their lifting speeds can be different. In other words, under the drive of the cylinder, the blade assembly and the fork structure can descend synchronously. When the fork structure descends to insert into the persimmon, the blade assembly can descend to one side of the persimmon, and the axis of the peeling motor can be roughly aligned with the center of the persimmon, thereby achieving synchronous positioning of the blade assembly and the fork structure relative to the persimmon.

[0021] During the peeling process, the fork motor drives the fork structure to rotate, which in turn rotates the persimmon. The peeling motor drives the blade assembly to rotate, and the axis of the peeling motor is roughly aligned with the center of the persimmon. This allows the blade assembly to peel the rotating persimmon completely from both the top and bottom. In short, before peeling the persimmon, the blade assembly of the peeling component moves closer to the persimmon synchronously as the fork structure of the fork assembly inserts into the persimmon's stem. This achieves coordinated positioning between the blade assembly and the fork structure, ensuring that the axis of the peeling motor is roughly aligned with the center of the persimmon. This ensures that the rotation center of the persimmon matches the feed trajectory of the blade assembly, resulting in a uniform cutting thickness and improved peeling effect. Furthermore, it also enhances the versatility of the persimmon peeling machine for peeling persimmons of different sizes. Attached Figure Description

[0041] To address the problems existing in the aforementioned related technologies, this utility model provides a persimmon peeling machine.

[0042] like Figure 1 and Figure 2 As shown in the figure, a persimmon peeling machine provided by this utility model embodiment includes a cover 7, a cylinder 8, a fork assembly 4, a transmission assembly 6, and a peeling assembly 5. The cover 7 is used to be installed on the base 1 of the persimmon peeling machine. The fork assembly 4 is used to be disposed above the feeding structure 3 of the persimmon peeling machine. The fork assembly 4 includes a sliding frame 43, a fork motor 42, and a fork structure 41. The cylinder 8 is fixed to the cover 7, and the piston rod of the cylinder 8 is fixedly connected to the sliding frame 43 for driving the sliding frame 43 to rise and fall. The fork structure 41 is used to insert or detach the persimmon 700 on the feeding structure 3. The fork motor 42 is fixedly installed on the sliding frame 43 and connected to the fork structure 41, and is used to drive the fork structure 41 to rotate the persimmon 700; the piston rod of the cylinder 8 is connected to the peeling assembly 5 through the transmission assembly 6, and is used to drive the peeling assembly 5 and the sliding frame 43 to lift and lower in linkage through the transmission assembly 6; the peeling assembly 5 includes a peeling motor 51, a sliding frame 52 and a blade assembly 53, the peeling motor 51 is connected to the sliding frame 52 and the blade assembly 53 respectively, and is used to drive the blade assembly 53 to rotate to peel the persimmon 700.

[0043] Specifically, cylinder 8 is fixed to the cover 7 so as to provide a mounting base for cylinder 8 through the cover 7.

[0044] The persimmon peeling machine also includes a base 1, a feeding structure 3 which can be a turntable device, the feeding structure 3 can be installed on the base 1, and the cover 7 can be fixed to the base 1 by bolts, fasteners or welding.

[0045] 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.

[0046] In addition, it should be noted that the persimmon peeling machine of this application is not limited to cutting persimmons 700, but can also be used to cut other fruits that are similar in shape to persimmons 700 and need to be peeled, such as apples and pears.

[0047] The sliding frame 43 and the cover 7 can be slidably connected in the following manner, for example, by combining Figure 3 As shown, the sliding frame 43 can be slidably connected to the cover 7 through the sliding base and rail structure, thereby ensuring the stability of the vertical lifting and lowering movement of the sliding frame 43 relative to the cover 7.

[0048] The fork structure 41 can be a cylindrical structure at the top and a multi-clawed fork, such as a three-clawed fork, at the bottom.

[0049] Cylinder 18 can be a telescopic cylinder component.

[0050] The persimmon peeling machine may also include a connecting rod and a hook-shaped blade. The hook-shaped blade is fixedly connected to the sliding frame 43 or the fork motor 42 via the connecting rod, and the hook-shaped blade is located around the fork structure 41. The hook-shaped blade is used to cut the persimmon petals of the persimmon 700. In this application, the hook-shaped blade can be used to both cut the persimmon petals and remove the persimmon stem.

[0051] As an example, the persimmon peeling machine also includes a PLC controller. Cylinder 8 and fork motor 42 are electrically connected to the output of the PLC controller, allowing the PLC controller to control the operation of cylinder 8 and fork motor 42. Fork motor 42 can be a DC motor. Peeling motor 51 can be a stepper motor.

[0052] Combination Figure 1As shown, the persimmon 700 can complete the feeding, peeling and unloading operations in the following manner: For example, the feeding structure 3 can adopt a turntable device, and multiple, for example, four feeding positions are arranged along its circumference. Each feeding position can be used to place the persimmon 700, and there can also be multiple work stations along the circumference of the turntable device. The position corresponding to the fork assembly 4 can be defined as the peeling work station, and the position for unloading can be defined as the unloading work station. The persimmons 700 to be peeled can be placed on the feeding position of the turntable device. If the turntable device rotates clockwise, when the turntable device rotates the persimmons 700 on the feeding position to the peeling position, the PLC controller will send a start signal to the cylinder 8, so that the cylinder 8 starts working after receiving the signal. The cylinder 8 drives the sliding frame 43 to drive the fork motor 42 and the fork structure 41 to descend, so that the fork structure 41 can be inserted into the persimmon 700. Then, the PLC controller sends a start signal to the fork motor 42, the fork motor 42 starts to run, and drives the fork structure 41 to rotate the persimmon 700. The peeling component 5 is located on one side of the fork component 4, so that the blade assembly 53 in the peeling component 5 can peel the persimmons 700 in the rotating state.

[0053] The hook-shaped blade can be directly or indirectly fixed to the sliding frame 43 or the fork motor 42 via a connecting rod. Therefore, the hook-shaped blade can move up and down together with the sliding frame 43 or the fork motor 42 under the drive of the cylinder 8. The hook-shaped blade moves up and down with the fork structure 41 and descends to the periphery of the persimmon 700's stem position. Since the fork motor 42 drives the persimmon 700 to rotate (or around) through the fork structure 41... Figure 1 (The Z-axis in the coordinate system moves in a circular motion), so that the persimmon 700 can rotate relative to the hook-shaped blade fixed on the sliding frame 43 or the fork motor 42. Then the fixed hook-shaped blade can cut the petals of the persimmon 700 that has rotated at least one revolution.

[0054] An inclined chute is set on the machine base 1 at the position corresponding to the unloading station. A first collection box can be placed below the inclined chute. A vertically extending cylinder three is set below the unloading station. The turntable device has a through hole at each unloading station off-center. The turntable device can rotate the persimmon 700 that has been peeled at the peeling station to the unloading station. The piston rod of the cylinder three passes through the through hole to lift the persimmon 700 and separate it from the unloading station. The persimmon 700 falls along the inclined chute into the first collection box under the action of gravity. Therefore, the first collection box is used to collect the persimmon 700 that has been peeled and had its petals cut off.

[0055] In this embodiment, the persimmon peeling machine may include a feeding structure 3 for feeding and a base 1, wherein the feeding structure 3 may be installed on the base 1; the persimmon peeling machine may include a fork assembly 4, a cover 7, a transmission assembly 6, a peeling assembly 5 and a cylinder 8 fixed on the cover 7, the cover 7 may be fixedly installed on the base 1, and the fork assembly 4 and the transmission assembly 6 are both located above the feeding structure 3.

[0056] The peeling motor 51 is fixedly connected to the sliding frame 52, therefore, the sliding frame 52 provides an installation base for the peeling motor 51.

[0057] The persimmon 700 can be peeled in the following way: for example, the feeding structure 3 transfers the persimmon 700 to be peeled to the area below the fork assembly 4. Since the fork motor 42, which is fixed on the sliding frame 43, is connected to the fork structure 41, and the piston rod of the cylinder 8 is fixedly connected to the sliding frame 43, the cylinder 8 can drive the sliding frame 43 to drive the fork motor 42 and the fork structure 41 to descend synchronously until the fork structure 41 descends to the stem position of the persimmon 700. Since the piston rod of the cylinder 8 is also connected to the transmission assembly... The component 6 is fixedly connected to the peeling component 5 so that the peeling component 5 and the sliding frame 43 can be linked and lifted by the transmission component 6. However, the lifting speeds of the two can be different. In other words, under the drive of the cylinder 8, the knife holder assembly 53 and the fork structure 41 can be lowered synchronously. When the fork structure 41 is lowered to the point of being inserted into the persimmon, the knife holder assembly 53 can be lowered to the side of the persimmon, and the axis of the peeling motor 51 can be roughly aligned with the center of the persimmon 700, thereby achieving synchronous positioning of the knife holder assembly 53 and the fork structure 41 relative to the persimmon.

[0058] During the peeling operation, the fork motor 42 drives the fork structure 41 to rotate, thereby rotating the persimmon 700. The peeling motor 51 drives the blade assembly 53 to rotate. The axis of the peeling motor 51 can be roughly aligned with the center of the persimmon 700, so that the blade assembly 53 can completely peel the rotating persimmon 700 from the top and bottom of the persimmon 700 in a rotating manner. In short, before peeling the persimmon 700, the blade assembly 53 of the peeling component 5 rotates with the fork assembly. The fork structure 41 of component 4 is inserted into the stem of the persimmon 700 and moves synchronously closer to the persimmon 700, thereby achieving synchronous positioning of the blade assembly 53 and the fork structure 41. This ensures that the axis of the peeling motor 51 is roughly aligned with the center of the persimmon 700, ensuring that the rotation center of the persimmon matches the feed trajectory of the blade assembly 53. Consequently, the cutting thickness of the persimmon is made uniform, thus improving the peeling effect. In addition, it also helps to improve the versatility of the persimmon peeling machine for peeling persimmons 700 of different sizes.

[0059] Optionally, combined Figure 1 and Figure 3As shown, the transmission component 6 is a pulley assembly;

[0060] And / or, the ratio of the lifting displacement of the fork structure 41 to that of the peeling assembly 5 is 2:1.

[0061] Specifically, the transmission component 6 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.

[0062] Since the fork motor 42, which is fixed on the sliding frame 43, is connected to the fork structure 41, the sliding frame 43 and the fork structure 41 can move up and down synchronously. The transmission component 6 can be fixedly connected to the peeling motor 51 of the peeling component 5 or the sliding frame 52, so that the transmission component 6 can drive the entire peeling component 5 to move up and down.

[0063] In this optional embodiment, before peeling the persimmon 700, cylinder 8 can drive sliding frame 43 to move the fork structure 41 downwards and closer to the stem of the persimmon 700. One end of the steel wire rope 64 in the transmission assembly 6 is fixedly connected to sliding frame 43, and the transmission assembly 6 is fixedly connected to the peeling assembly 5. Thus, while cylinder 8 drives the fork structure 41 downwards and inserts it into the stem of the persimmon 700, the transmission assembly 6 can drive the peeling motor 51 of the peeling assembly 5 to move downwards synchronously, so that the blade assembly 53 moves synchronously closer to the persimmon. 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 stem position of the persimmon 700 to the vertical displacement (i.e., the displacement in the height direction) of the peeling motor 51 of the peeling assembly 5 moving from the highest point to the lowest point is 2:1. This ensures that when the fork structure 41 is inserted into the persimmon, the output shaft of the peeling motor 51 is approximately at the center height of the persimmon. In other words, the shaft height of the peeling motor 51 is aligned with the center position of the persimmon, making it suitable for persimmons 700 of different sizes.

[0064] Optionally, combined Figure 1 and Figure 3As shown, the persimmon peeling machine also includes a housing 2, which is fitted outside the cover 7. The transmission assembly 6 includes a guide wheel 61, a guide wheel 62, a guide wheel 63, and a wire rope 64. The guide wheel 61 is rotatably disposed inside the housing 2 and corresponds to one side of the sliding frame 43. The guide wheel 62 is rotatably connected inside the housing 2 to the side of the guide wheel 61 away from the sliding frame 43, and the guide wheel 62 is above the guide wheel 61. The guide wheel 63 is rotatably disposed on the side of the guide wheel 62 away from the guide wheel 61. The guide wheel 63 is fixedly connected to the peeling motor 51 or the sliding frame 52. The two ends of the wire rope 64 are fixedly connected to the sliding frame 43 and the housing 2, respectively. The wire rope 64 is wound around the guide wheel 61, the guide wheel 62, and the guide wheel 63 in sequence.

[0065] Specifically, the housing 2 can be fixedly installed on the upper part of the base 1 of the persimmon peeling machine by means of bolts, fasteners or welding. The cover 7 can be fixedly installed on the base 1. The cylinder 8 can be fixedly connected to the cover 7. The sliding frame 43 in the fork assembly 4 can be slidably connected to the cover 7, so that the sliding frame 43 can be raised and lowered under the driving action of the cylinder 8. Therefore, at least part of the sliding frame 43 can be located outside the top of the cover 7. The housing 2 is fitted on the cover 7, so that the fork assembly 4, the cylinder 8, the transmission assembly 6 and the peeling assembly 5 can be encapsulated inside the housing 2 from the outside, which can play a safety protection role for the persimmon peeling machine.

[0066] The blade assembly 53 can be located inside the cover 7, and at least part of the cylinder 8 can be located outside the cover 7 but inside the housing 2. The entire transmission assembly 6 and the peeling motor 51 are located outside the cover 7, thereby preventing persimmon peels or persimmon juice generated by the blade assembly 53 located inside the cover 7 during the persimmon peeling process from splashing onto the transmission assembly 6 and the peeling motor 51, thus affecting the normal operation of the transmission assembly 6 and the peeling motor 51.

[0067] Guide wheel 1 61 and guide wheel 2 62 can be mounted on chassis 2 in the following manner, for example, by combining Figure 3 and Figure 4As shown, the persimmon peeling machine also includes a mounting base 65, a first fastener, a second fastener, and a mounting base 66. The mounting base 65 can be fixed to the inner wall of the machine housing 2 by bolts. The first fastener passes through the guide wheel 61, the mounting base 65, and the machine housing 2, so that the guide wheel 61 is mounted to the inner wall of the machine housing 2 through the mounting base 65, and the guide wheel 61 can rotate around the first fastener. The guide wheel 61 can be located on the side of the cylinder 8 away from the sliding frame 43. Similarly, the mounting base 66 can be fixed to the inner wall of the machine housing 2 by bolts. The guide wheel 62 is fixed to the inner wall of the housing 2 by bolts. The second fastener passes through the guide wheel 62, the mounting base 66 and the housing 2 to install the guide wheel 62 on the inner wall of the housing 2. The guide wheel 62 can rotate around the second fastener. The guide wheel 62 can be located on the side of the guide wheel 61 away from the sliding frame 43. The height of the guide wheel 62 can be higher than that of the guide wheel 61 to ensure a certain drag height for the peeling motor 51. Both the guide wheel 61 and the guide wheel 62 can be fixed pulley structures.

[0068] The guide wheel 63 can be fixedly connected to the sliding frame 52, combined with Figure 3 As shown in the figure; or, the guide wheel 63 can also be directly fixedly connected to the peeling motor 51 (not shown in the figure).

[0069] Guide wheel 63 can be fixedly connected to sliding frame 52 outside the peeling motor 51 in the following manner, for example, by combining Figure 5 As shown, the persimmon peeling machine also includes a third fastener. A mounting hole 521 is provided on the sliding frame 2 52. The third fastener passes through the mounting hole 521 of the guide wheel 3 63 and the sliding frame 2 52 to fix the guide wheel 3 63 onto the sliding frame 2 52. The guide wheel 3 63 can drive the sliding frame 2 52 to move up and down synchronously; therefore, the guide wheel 3 63 can be a movable pulley. The first, second, and third fasteners can be bolted or pin-driven structures.

[0070] Both ends of the wire rope 64 can be connected to the sliding frame 43 and the machine box 2 by means of hooks or rings, which can improve the convenience of connecting the wire rope 64 to the sliding frame 43 and the machine box 2.

[0071] In this optional embodiment, when the cylinder 8 drives the sliding frame 43 to slide downward relative to the cover 7, one end of the wire rope 64 is fixedly connected to the side of the sliding frame 43 near the guide wheel 61, and the other end is fixedly connected to the top of the inside of the housing 2. The wire rope 64 is wound around the guide wheel 61, the guide wheel 62 and the guide wheel 63 in sequence. As the sliding frame 43 descends, the wire rope 64 will pull the guide wheel 63. The guide wheel 63 is connected to the peeling assembly 5, which will drive the peeling assembly 5 to descend synchronously. This allows the knife holder assembly 53 in the peeling assembly 5 to move synchronously closer to the persimmon 700 as the fork structure 41 is inserted into the persimmon 700, preparing for subsequent peeling. When peeling is complete, the cylinder 8 drives the sliding frame 43 to rise, and the wire rope 64 drives the guide wheel 63 to make the peeling component 5 rise synchronously with the sliding frame 43, realizing the linkage lifting and lowering of the peeling component 5 and the fork component 4. The whole process is realized through a mechanical transmission structure, and the PLC controller controls the cylinder 8 to indirectly control the action of the transmission component 6, ensuring the coordination of the actions of the fork component 4 and the peeling component 5.

[0072] Optionally, combined Figures 6 to 8 As shown, the cover 7 is provided with a guide hole 71, the motor shaft of the peeling motor 51 passes through the guide hole 71 and is fixedly connected to the knife holder assembly 53, and the motor shaft of the peeling motor 51 is used to move up and down along the guide hole 71.

[0073] Specifically, the motor housing of the peeling motor 51 can be fixedly installed in the sliding frame 52 by means of bolt fasteners.

[0074] Combination Figure 7 As shown, a guide hole 71 is provided on the cover 7 at a position corresponding to the motor shaft of the peeling motor 51, so that the motor shaft of the peeling motor 51 can pass smoothly through the guide hole 71 and be fixedly connected to the tool holder assembly 53. The guide hole 71 can be a vertically extending waist-shaped hole, an oblong hole, or a rectangular hole.

[0075] Since the guide hole 71 can extend vertically, the motor shaft of the peeling motor 51 can move up and down with the transmission component 6 within the guide hole 71, so as to avoid the cover 7 from obstructing the lifting and lowering action of the peeling motor 51.

[0076] in, Figure 6 This is a schematic diagram of the structure in the first position, such as the high position, where the peeling motor 51 and the knife assembly 53 are in the first position. At this time, the motor shaft of the peeling motor 51 can contact or be close to the top of the guide hole 71, while the knife assembly 53 is in the high position where the peeling of the persimmon 700 begins. Figure 8This is a schematic diagram of the structure in the second position, such as the low position, where the peeling motor 51 and the knife assembly 53 are in the second position. At this time, the motor shaft of the peeling motor 51 can contact or be close to the bottom end of the guide hole 71, while the knife assembly 53 is in the low position after the bottom of the persimmon 700 has been peeled.

[0077] In this optional embodiment, the height displacement of the peeling motor 51 can be less than or equal to the height of the guide hole 71 along the vertical direction, so as to ensure that the peeling motor 51 has sufficient lifting height so that the cover 7 will not interfere with the lifting action of the peeling motor 51.

[0078] Optionally, the tool post assembly 53 may adopt the following structural configuration, for example, combined with Figure 9 As shown, the knife assembly 53 includes a knife holder 531, a knife handle 532, a second cylinder 533, a knife post 534, and a peeling blade 535. The peeling motor 51 is fixedly connected to the knife holder 531 and is used to drive the knife holder 531 to rotate. One end of the knife handle 532 is hinged to the knife holder 531. The knife post 534 is fixed to the end of the knife handle 532 away from the knife holder 531. The peeling blade 535 is fixedly installed on the knife post 534. The second cylinder 533 is fixedly installed on the knife holder 531. The piston rod of the second cylinder 533 is fixedly connected to the knife handle 532 and is used to drive the knife handle 532 to rotate, so that the peeling blade 535 moves closer to or away from the persimmon 700.

[0079] Specifically, the motor shaft of the peeling motor 51 passes through the guide hole 71 of the cover 7 and is fixedly connected to the tool holder 531 of the tool holder assembly 53 via a coupling, so that the tool holder 531 can rotate synchronously with the motor shaft of the peeling motor 51. One end of the tool handle 532 is hinged to the tool holder 531 via a rotating component such as a hinge or pin structure, so that the tool handle 532 can rotate relative to the tool holder 531. The tool holder 534 is fixedly connected to the tool handle 532 by fasteners or welding, so that the tool holder 534 is fixedly mounted on the tool handle 532.

[0080] Cylinder 2 533 is fixedly installed in the knife holder 531 by means of bolts, fasteners, or welding. The end of the piston rod of cylinder 2 533 is fixedly connected to the knife handle 532, which is used to drive the knife handle 532 to rotate relative to the knife holder 531, so that the knife handle 532 drives the peeling blade 535 to move closer to or away from the persimmon 700. A three-position knob for adjusting the speed of the peeling motor 51 is fixedly installed on the machine base 1. The three-position knob is connected to the input terminal of the PLC controller.

[0081] The peeler blade 535 can be fixedly installed on the blade holder 534 by means of snap-fit, plug-in, bolt, etc., so the blade holder 534 can be used as the mounting base for the peeler blade 535.

[0082] The peeling blade 535 can be a utility knife blade or other types of blades. Any blade that can cut the skin of persimmons is suitable for this technical solution, and no specific limitation is made here.

[0083] In this optional embodiment, when the transmission assembly 6 drives the sliding frame 52 to rise and fall synchronously with the cover 7 and the fork assembly 4, so that the peeling blade 535 of the blade holder assembly 53 reaches a suitable height, for example, the PLC controller can send a control signal to the cylinder 533 according to the size of the persimmon 700. The piston rod of the cylinder 533 retracts to drive the handle 532 to rotate around the hinge point of the blade holder 531, so that the peeling blade 535 is close to the persimmon 700 to ensure the peeling effect of the persimmon 700. After adjusting the contact distance between the peeling blade 535 and the persimmon 700, the PLC controller synchronously sends a start and speed control signal to the peeling motor 51. At this time, the peeling motor 51 drives the blade holder 531 to rotate, and then, as the blade holder 531 rotates, it will drive the handle 532. The blade holder 534 and the peeling blade 535 rotate around the persimmon 700, causing the peeling blade 535 to rotate from the top of the persimmon 700 to the bottom tip for peeling. During this peeling process, the rotation axis of the blade holder 534 always points to the center of the persimmon, ensuring the peeling effect. After peeling is completed, the PLC controller will send a control signal to the cylinder 533 again, causing the piston rod of the cylinder 533 to extend and drive the handle 532 to rotate around the hinge point of the blade holder 531, so that the peeling blade 535 is removed from the persimmon 700. At the same time, the PLC controller will also send a control signal to the peeling motor 51 again, causing the peeling motor 51 to drive the blade holder 531, handle 532, blade holder 534 and peeling blade 535 to rotate to the initial position (i.e., the high position), preparing for the next peeling.

[0084] Optionally, combined Figure 9 As shown, the tool holder assembly 53 also includes an elastic element 536, the two ends of which are respectively connected to the tool handle 532 and the tool holder 531.

[0085] Specifically, the elastic element 536 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 elastic element 536 can be a tension elastic rope or a tension spring.

[0086] A hole structure or a hook structure can be provided on the tool holder 531 to facilitate quick connection of one end of the elastic element 536 to the tool holder 531. A hole structure or a hook structure can also be provided on the tool shank 532 to facilitate quick connection of the other end of the elastic element 536 to the tool shank 532. Specifically, one end of the tool holder 531 is hinged to one end of the tool shank 532, and one end of the elastic element 536 can be connected to the end of the tool holder 531 away from the tool shank 532.

[0087] The handle 532 may have a plate-like structure and may have a certain deformation property, such as being able to produce slight deformation under the tension of the elastic element 536, so that the peeling blade 535 can better approach persimmons of different sizes.

[0088] In this optional embodiment, before peeling the persimmon 700, the peeling blade 535 of the blade assembly 53 is close to the persimmon 700. Since the persimmons 700 are of different sizes, the distance between the peeling blade 535 and persimmons of different sizes is not equal. Therefore, when peeling the persimmon 700, the piston rod of the second cylinder 533 retracts, which can drive the handle 532 to rotate relative to the blade holder 531, so that the peeling blade 535 is close to the persimmon 700. At this time, the contraction and tension of the elastic element 536 can make the peeling blade 535 even closer to the persimmon 700, thereby improving the peeling effect of the persimmon 700. After peeling is completed, the piston rod of the second cylinder 533 extends, which can drive the handle 532 to rotate relative to the blade holder 531, so that the peeling blade 535 is disengaged from the persimmon 700. At this time, the elastic element 536 will be stretched.

[0089] Optionally, combined Figure 10 As shown, the knife handle 532 is provided with a plurality of connection holes 5321 arranged at intervals. The arrangement direction of the plurality of connection holes 5321 is parallel to the extension direction of the knife handle 532. One end of the elastic member 536 is detachably connected to one of the connection holes 5321.

[0090] Specifically, the spacing of the multiple connecting holes 5321 can be parallel to the extension direction of the tool holder 532. The end of the elastic element 536 away from the tool holder 531 can be detachably connected to the connecting holes 5321 by means of hooking, snapping, or other methods.

[0091] In this optional embodiment, since the elastic element 536 needs to exert a pulling force on the handle 532 before and after peeling each persimmon 700, the elastic element 536 is prone to fatigue after a period of use, thereby affecting the pulling force value on the handle 532 and consequently affecting the peeling effect on the persimmon 700. Therefore, after the elastic element 536 becomes fatigued, the user can adjust the connection between the end of the elastic element 536 away from the blade holder 531 and the connection holes 5321 at different positions on the handle 532 to effectively adjust the pulling force value of the elastic element 536 on the handle 532. Consequently, the peeling blade 535 can better fit the outer surface of the persimmon 700 again, thus eliminating the need to replace the elastic element 536, thereby reducing the replacement cost of the elastic element 536 and extending its service life.

[0092] Optionally, combined Figure 7 and Figure 11As shown, the persimmon peeling machine also includes a detection and positioning component 2 9. The detection and positioning component 2 9 includes a second proximity switch 91 and an ear piece 92. The second proximity switch 91 is fixedly installed on the sliding frame 2 52, and the ear piece 92 is fixedly installed on the blade holder assembly 53 for sensing contact with the second proximity switch 91.

[0093] Specifically, the second proximity switch 91 can be directly or indirectly fixedly mounted on the sliding frame 52 via a connecting plate. The lug 92 can be fixedly mounted on the end of the tool holder 531 of the tool post assembly 53 away from the tool handle 532.

[0094] The second proximity switch 91 can be arranged in the following manner, for example, combined with Figure 7 and Figure 11 As shown, the detection and positioning component 2 9 includes an ear piece 92 and two second proximity switches 91. The side wall of the cover 7 is provided with two vertically spaced perforations 72. The end of each second proximity switch 91 passes through the corresponding perforation 72 and corresponds to the knife holder 531. The vertical height of each perforation 72 matches the vertical height of the guide hole 71, so that the second proximity switch 91 moves up and down with the sliding frame 2 52 within its respective perforation 72.

[0095] Before peeling the persimmon, the upper second proximity switch 91 corresponds to the position of the ear piece 92 fixed on the blade holder 531. The upper second proximity switch 91 can be used to detect or determine whether the blade holder 531 is in a high position, which can be understood as the starting position for peeling the persimmon. The blade holder 531 rotates under the drive of the peeling motor. After the persimmon is peeled from top to bottom, the lower second proximity switch 91 corresponds to the position of the ear piece 92 fixed on the blade holder 531. This allows the lower second proximity switch 91 to be used to detect or determine whether the blade holder 531 is in a low position, which can be understood as the ending position for completing the peeling of the persimmon.

[0096] The second proximity switch 91 can be electrically connected to the input terminal of the PLC controller, and the output terminal of the PLC controller is electrically connected to the peeling motor 51.

[0097] In this optional embodiment, during the operation of the peeling assembly 5, the peeling electric drive blade holder 531 rotates, thereby causing the ear piece 92 to rotate together with the blade holder 531. When the ear piece 92 rotates into the sensing range of the second proximity switch 91, the second proximity switch 91 will detect the presence of the ear piece 92 and generate a sensing signal. For example, the second proximity switch 91 transmits this signal to the PLC controller. Based on this signal, the PLC controller can accurately determine the current position of the blade holder 534 and the peeling blade 535 in the peeling assembly 5. If the ear piece 92 on the blade holder 531 leaves the detection range of the second proximity switch 91 under the drive of the peeling motor 51, the PLC controller can control the peeling motor 51 to stop working or rotate in another direction.

[0098] Optionally, combined Figure 12 As shown, the peeling assembly 5 also includes a first sliding member 54 and a second sliding member 55. The first sliding member 54 is fixedly connected to the sliding frame 52, and the second sliding member 55 is fixedly connected to the inner wall of the housing 2. The first sliding member 54 and the second sliding member 55 are slidably connected vertically.

[0099] Specifically, the first sliding member 54 can be fixed to the side wall of the sliding frame 52 away from the peeling motor 51 by means of bolts or fasteners, and the second sliding member 55 can be fixed to the inner wall of the housing 2 by means of bolts or fasteners.

[0100] When the first sliding member 54 is a sliding block structure, the second sliding member 55 can be a vertically arranged slide rail structure, see Figure 12 As shown; when the first sliding member 54 is a slide rail structure, the second sliding member 55 can be a vertically arranged slide block structure.

[0101] In this optional embodiment, since the cylinder 8 can drive the sliding frame 52 in the peeling assembly 5 to move up and down through the transmission assembly 6, the sliding frame 52 is vertically slidably connected to the second sliding member 55 fixed to the inner wall of the housing 2 through the first sliding member 54. Thus, the sliding connection between the first sliding member 54 and the second sliding member 55 provides guidance and stability for the vertical movement of the peeling assembly 5.

[0102] Optionally, the fork structure 41 can adopt the following structural method, combined with Figure 2 and Figure 13 As shown, the fork structure 41 includes a cylindrical part 411 and a plurality of fork claw parts 412. The cylindrical part 411 is coaxially connected to the motor shaft of the fork motor 42. The plurality of fork claw parts 412 are arranged in a ring at intervals around the central axis of the cylindrical part 411 and are respectively connected to the cylindrical part 411.

[0103] Specifically, the top end of the cylindrical portion 411 can be fixedly connected to the motor shaft of the fork motor 42 by means of, for example, threaded connection, plug connection, or bolt fastener. Multiple fork pawl portions 412 are arranged in a ring at intervals and are respectively fixedly connected to the bottom end of the cylindrical portion 411.

[0104] The cylindrical part 411 and the multiple fork parts 412 can be constructed as an integral structure to ensure the mechanical strength of the fork structure 41.

[0105] Each fork portion 412 may have a rounded protrusion at its bottom end.

[0106] In this optional embodiment, since the cylindrical part 411 is coaxially and fixedly connected to the motor shaft of the fork motor 42, the cylindrical part 411 and the motor shaft of the fork motor 42 can be fixed as an integral structure to ensure that the motor shaft of the fork motor 42 can drive the fork structure 41 to rotate synchronously. Since the bottom end of the fork pawl part 412 of the fork structure 41 is provided with an arc protrusion, in other words, the bottom tip of the fork structure 41 does not need to be made so sharp, but has a slight arc. The purpose of doing so is to avoid the fork structure 41 from inserting too deeply into the persimmon 700, thereby damaging the persimmon 700.

[0107] The present invention provides a persimmon peeling machine, which further includes a machine base 1 and a feeding structure 3. The feeding structure 3 is installed on the machine base 1 and is used to transfer persimmons 700.

[0108] Specifically, the feeding structure 3 can be installed on the base 1, the cover 7 can be fixed to the base 1 by bolts or welding, and the chassis 2 can be fixed to the base 1 by bolts. Therefore, the base 1 can serve as the installation foundation for the feeding structure 3, the cover 7 and the chassis 2.

[0109] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
