Description

Technical Field

[0001] The utility model relates to the technical field of coconut processing, and particularly relates to a coconut shell grooving machine. Background Art

[0002] Coconut eggs are products after the complete coconut meat and coconut juice are separated from the coconut shell, and are one of the favorite fruits of people. At present, when making coconut eggs, the main method is to cut the shell manually. Since the coconut shell is spherical and has a relatively hard texture, it is not easy to operate with a knife by hand, resulting in a large labor intensity and being prone to causing harm to the operator.

[0003] The patent with the publication number of "CN217564861U" discloses a "coconut egg machine for coconut grooving and shelling processing", but this patent clamps the coconut in an up-and-down manner, which is prone to causing damage to the coconut eggs. In addition, the cutting tool has a large rotary diameter, and due to intermittent cutting, the impact on the coconut meat is prone to causing damage to the coconut eggs, and it will also generate relatively large vibration and noise to the equipment.

[0004] The patent with the publication number of "CN220211793U" discloses a "coconut shelling machine", but the clamping device of this patent has a complex mechanism, resulting in a relatively high cost. In addition, when using a wire wheel to cut off the fiber layer outside the hard core in this patent, the wire is prone to being blocked, increasing the cleaning process and affecting the processing efficiency.

[0005] Therefore, a coconut shell grooving machine is proposed. Summary of the Invention

[0006] The purpose of the utility model is to provide a coconut shell grooving machine, which can conveniently take out the coconut eggs from the coconut shell and reduce the impact damage to the coconut eggs at the same time.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A coconut shell grooving machine includes a frame. A reciprocating motion mechanism is arranged on the frame, and a clamping and rotating assembly for clamping the coconut and driving it to rotate is arranged on the reciprocating motion mechanism.

One end of the crank is hinged to the frame, the middle of the crank is hinged to one end of the connecting rod, and the other end of the connecting rod is connected to the sliding plate through a spring.

[0015] Preferably, a stop block is provided on the side wall of the sliding plate, and a positioning mechanism is provided on the frame. The positioning mechanism has a moving rod that abuts against the stop block.

[0016] Preferably, the positioning mechanism is a manual screw rod reciprocating mechanism or an electric reciprocating mechanism.

[0017] Preferably, a hand support frame mechanism for providing support for separating the coconut meat from the inner wall of the grooved coconut is further provided on the frame. The hand support frame mechanism includes a hand support frame provided on the frame.

[0018] Preferably, a soft knife guiding component is further provided on the hand support frame, and a soft knife tool can be inserted into the flat hole of the soft knife guiding component.

[0019] Preferably, a locking device for locking the sliding plate on the guide rail is further included.

Detailed implementation manners

[0046] The present invention will be further described below with reference to the drawings.

[0047] Embodiment 1

[0048] As Figure 1 shown, a coconut shell grooving machine of this embodiment includes a frame 1, a reciprocating motion mechanism 4 is arranged on the frame 1, a clamping and rotating assembly 2 for clamping the coconut 211 and driving it to rotate is arranged on the reciprocating motion mechanism 4, a cutting tool assembly 3 for grooving the coconut shell is arranged on the frame 1, and a middle support frame mechanism for separating the coconut meat from the coconut after grooving and providing support for taking it out is also arranged on the frame 1.

[0049] As Figure 8As shown, the hand support mechanism includes a hand support 8. The hand support 8 is installed on the frame 1 through hand support bolts 810. The hand support 8 has an arc-shaped portion that can be adapted to the coconut 211. A soft knife guiding member 830 is also provided on the hand support 8. A flat hole is provided on the soft knife guiding member 830, and the soft knife 840 is inserted into the flat hole of the soft knife guiding member 830.

[0050] During use, first, the coconut 211 is clamped and fixed by the clamping and rotating assembly 2. The clamping and rotating assembly 2 drives the coconut 211 to rotate. At this time, the tool 301 of the cutting tool assembly 3 also rotates at a high speed. Then, the reciprocating motion mechanism 4 moves the clamping and rotating assembly 2 and the coconut 211 to the tool 301 of the cutting tool assembly 3, and the tool 301 cuts and grooves the hard shell of the coconut 211. The formed annular groove 200 is as Figure 3 shown. After grooving, the reciprocating motion mechanism 4 drives the coconut 211 to move to the hand support. The reciprocating motion mechanism 4 is locked by the locking device, and the soft knife is inserted into the annular groove 200. The coconut 211 rotates at a low speed, so that the separation of the coconut egg and the coconut shell can be realized by the soft knife.

[0051] As Figure 3 and Figure 4 shown, the cutting tool assembly 3 includes a tool spindle 302. A tool 301 is installed at one end of the tool spindle 302 close to the clamping and rotating assembly 2. The other end of the tool spindle 302 is connected to a tool motor 303. An inclined angle is formed between the rotation axis of the tool 301 and the rotation axis of the clamping and rotating assembly 2. The angle of the inclined angle is 20° - 70°. This inclined angle is Figure 4 the "α" angle in. Through the setting of this inclined angle, the annular groove 200 can be smoothly opened on the surface of the coconut shell. The tool 301 can be a standard milling cutter to reduce the use cost; it can also be a special-shaped milling cutter similar to the shape of the hard shell to improve the grooving efficiency. A stepped cutting edge is provided at the end of the milling cutter to remove the excess fiber layer.

[0052] As Figure 1 and Figure 6 shown, the tool spindle 302 is installed on the frame 1. A motor mounting plate 101 for installing the tool motor 303 is also provided on the frame 1. The tool spindle 302 and the tool motor 303 can also be integrally provided. In this embodiment, in order to reduce the negative impact of the vibration of the tool cutting the coconut shell on the motor, the tool spindle 302 and the tool motor 303 are connected by a transmission belt 304. A belt adjusting bolt 102 is provided on the frame 1. The position of the tool motor 303 can be adjusted by adjusting the position of the motor mounting plate 101, and then the tightness of the transmission belt 304 can be adjusted. As Figure 1As shown, spindle motor shock absorbers 305 are provided between the mounting portion of the tool spindle 302 and the frame 1, and between the tool motor 303 and the motor mounting plate 101. The spindle motor shock absorbers 305 can be flat gaskets with certain elasticity, used to reduce the resonance impact on the frame 1 caused by the vibration during tool cutting of the coconut shell.

[0053] The tool spindle 302 can also be changed to a tool electric spindle. A tool 301 is installed at one end of the tool electric spindle close to the clamping and rotating assembly 2. The tool electric spindle contains a motor for driving the tool 301 to rotate.

[0054] As Figure 7 As shown, the reciprocating motion mechanism 4 includes a slide plate 401. Guide rails 105 for supporting the movement of the slide plate 401 are provided on the frame 1. The slide plate 401 is connected to a thrust mechanism for pushing it to move. In this embodiment, the thrust mechanism is a manual thrust rod 610, and the slide plate 401 is manually pushed to move left and right. This device also includes a locking device for locking the slide plate 401 on the guide rail 105. In this embodiment, the locking device is a handwheel screw open-loop locking portion 710, including a screw handwheel and an open loop with a threaded hole.

[0055] When using a soft knife to separate the coconut egg and the coconut shell, after the slide plate 401 drives the coconut 211 to move left to the corresponding position of the supporting hand frame 8, tighten the handwheel screw locking portion 710 to lock the slide plate 401 on the guide rail 105 to prevent the slide plate 401 from moving during this process. In this embodiment, the guide rail 105 uses an ordinary guide rod. To improve the precision of the equipment operation, other guide rail forms such as dovetail groove slide rails and linear slide rails can also be used.

[0056] As Figure 2As shown, the clamping and rotating assembly 2 includes a rotating mounting base 204 disposed on the sliding plate 401. A rotating shock absorber 205 is provided between the rotating mounting base 204 and the sliding plate 401. The rotating shock absorber 205 can be a flat pad with certain elasticity, such as a rubber pad. A bearing platform 203 for loading coconuts is provided on the rotating mounting base 204. Three clamping claws 201 for clamping the coconut 211 are provided on the bearing platform 203. A clamping handle 208 is provided on the side wall of the bearing platform 203. The rotating mounting base 204 is connected to a rotating speed reducer 206 that drives its rotation. A diamond mesh 202 is provided on the inner wall of the clamping claw 201, which can increase the frictional resistance of clamping and improve the reliability of clamping. The rotating motor 207 drives the bearing platform 203 to rotate through the rotating speed reducer 206. During actual use, the bearing platform 203 can use a standardized self-centering three-jaw chuck to reduce the equipment cost. A clutch can be provided in the rotating speed reducer 206 for manually reciprocatingly rotating the coconut to perform targeted cutting on a locally thicker coconut shell. In this embodiment, in order to optimize the overall visual effect of the equipment, the bearing platform 203 is installed above the sliding plate 401, and the rotating motor 207 and the rotating speed reducer 206 are installed below the sliding plate 401 ( Figure 2 the sliding plate 401 is not shown in the figure).

[0057] As Figure 1 and Figure 7 shown, a stop block 402 is provided on the side wall of the sliding plate 401, and a positioning mechanism is provided on the frame 1. The positioning mechanism has a moving rod 5 that abuts against the stop block 402. In this embodiment, the positioning mechanism is a manual screw rod reciprocating mechanism 510. During the process of grooving the coconut shell, after the coconut 211 and the cutting tool 301 rotate, the sliding plate 401 loaded with the coconut 211 moves from left to right until the stop block 402 abuts against the moving rod 5. Rotate the handwheel of the manual screw rod reciprocating mechanism 510 to move the moving rod 5 to the right. Under the push of the thrust mechanism, the stop block 402 and the moving rod 5 always abut against each other, so that the cutting tool 301 grooves the coconut shell, and thus a circular groove 200 is gradually machined until the coconut meat leaks out of the coconut shell.

[0058] As Figure 1 and Figure 5As shown in the figure, this embodiment further includes a limit plate assembly 310 for restricting the moving distance of the coconut. The limit plate assembly 310 includes a limit fixing seat 313 installed on the frame 1. A jacket 312 is arranged inside the limit fixing seat 313, and a limit plate 311 is arranged in the flat hole of the jacket 312. During the process of grooving the coconut, as the coconut gradually moves to the right, the coconut meat leaks out from the coconut shell. At this time, the hard coconut shell contacts the left end face of the limit plate 311 and cannot continue to move to the right. To facilitate the limit plate 311 to cut into the fiber layer, a cutting edge 300 is arranged on the limit plate 311. The cutting edge 300 can smoothly cut a slit on the fiber layer on the surface of the coconut shell, enabling the limit plate 311 to smoothly approach the hard coconut shell, and then limit the rightward movement of the coconut 211, thereby restricting the cutting depth of the cutter 301 on the coconut shell. The bolt on the jacket 312 can fix the limit plate 311. After loosening the fixing handle 314, rotating the adjusting handle 315 can gradually push the jacket 312 to move, realizing fine adjustment of the position of the limit plate 311 to adjust the cutting depth of the cutter 301 on the coconut shell. After adjusting to the appropriate position, tighten the fixing handle 314.

[0059] When the utility model is in use, first fix the coconut 211 on the clamping and rotating assembly 2. The coconut 211 rotates at a low speed and the cutter 301 rotates at a high speed. Then, under the action of the manual thrust rod 610, the coconut moves to the right until the outer side contacts the cutter 301, and a groove is opened on the surface of the coconut. During this process, as the handwheel in the positioning mechanism 510 rotates, the moving rod moves to the right, and the coconut 211 gradually moves to the right until the coconut meat leaks out from the opened annular groove. To avoid excessive grooving depth, the left end face of the limit plate 311 is used to limit the rightmost position of the coconut. After grooving is completed, the coconut 211 moves to the left until the supporting bracket corresponds to the position of the annular groove 200. Then tighten the handwheel screw locking part 710, and the coconut 211 rotates slowly to make the soft knife move inside the coconut, realizing the separation of the coconut egg from the coconut shell.

[0060] Embodiment Two

[0061] The difference between this embodiment and Embodiment One is that the positioning mechanism is no longer provided, and the cutter is gradually cut into layer by layer during grooving through the layer depth slide plate assembly.

[0062] As Figure 9 — Figure 12As shown in the figure, a layer-depth slide plate assembly 98 for grooving the coconut outer skin layer by layer is provided on the rack 1. The layer-depth slide plate assembly 98 includes a cutting-layer depth slide plate 981, and the cutting-layer depth slide plate 981 has a sliding surface 982 for limiting the cutting depth. During the process of the coconut moving to the right and being grooved by the cutter 301, the coconut shell first contacts the sliding surface 982. There is a cutting-layer depth gap between the machining surface of the cutter 301 (i.e., the milling cutter) and the sliding surface 982, which controls the depth of the milling cutter cutting into the coconut shell per revolution. As the grooving gradually deepens, the coconut gradually moves to the right until the hard coconut shell contacts the end step 983 of the milling cutter. At this time, the coconut cannot move further to the right, achieving the final limit of the cutting depth of the annular groove 200.

[0063] The other structures of this embodiment are the same as those of Embodiment 1.

[0064] Embodiment 3

[0065] As Figure 13 —14 shows, in this embodiment, when the thrust mechanism uses a manual thrust rod 610, the locking device can also be changed from a handwheel screw open-loop locking part 710 to a hand-operated cam open-loop locking part 720. By pulling the cam, it can be locked on the guide rail 105 to prevent the slide plate 401 from moving. Pulling the cam in the opposite direction will release the lock. Or adopt the form of cooperation between a clamping groove 730 and a fastening screw 731 (the screw is preferably a large square head screw). The clamping groove 730 is arranged at the bottom of the hand support 8, and the fastening screw 731 protrudes from the upper end surface of the slide plate 401. After the slide plate 401 drives the coconut 211 to move left to the corresponding position of the hand support, the movement of the slide plate 401 can be restricted by the hand-operated cam clamping part 720, or the movement of the slide plate 401 can be restricted by the form of cooperation between the clamping groove and the screw.

[0066] In addition, in this embodiment, the locking mechanism for returning to the hand support can also be no longer set, and the positioning mechanism can be changed from a manual screw reciprocating mechanism 510 to an electric reciprocating mechanism 520. The electric reciprocating mechanism 520 can use a motor and a reducer to drive the moving rod 5 to move to the right. The thrust mechanism is changed from a manual thrust rod 610 to a crank-slider and spring composite thrust rod 620. The crank-slider and spring composite thrust rod 620 has a crank 621 and a connecting rod 622. An installation block 624 is arranged on the rack 1. One end of the crank 621 is hinged to the ear plate hole of the installation block 624, the middle part of the crank 621 is hinged to one end of the connecting rod 622, and the other end of the connecting rod 622 is connected to the slide plate 401 through a spring 623. A groove for accommodating the connecting rod 622 is arranged on the installation block 624.

[0067] Before grooving the coconut, first operate the handle ball on the crank 621 of the crank-slider and spring composite thrust rod 620 to rotate the crank 621 clockwise. After passing the dead center of the crank-slider mechanism, it stops when it touches the right corner 631 of the mounting block 624. The slide plate 401 is pushed to move to the right by the spring 623 to ensure that the stop block 402 is always in contact with the moving rod 5. During the coconut grooving process, the electric reciprocating mechanism 520 drives the moving rod 5 to move to the right by a motor and a reducer. As the moving rod 5 moves to the right, the spring 623 pushes the slide plate 401 to move to the right accordingly, so that the cutter 301 cuts into the hard shell, thereby improving the automation degree of the equipment.

[0068] As Figure 14 shown, after grooving is completed, operate the handle ball on the crank 621 to rotate the crank 621 counterclockwise. After passing the dead center of the crank-slider mechanism, it stops when it touches the left corner 632 of the fixed block 624. The convex head on the right side of the connecting rod 622 pulls the slide plate 401 to move to the left to the corresponding position of the hand support, positioning the slide plate 401, and thus eliminating the need for a locking device.

[0069] At the same time, the hand support 8 of this embodiment is installed on the frame 1 through the hand support hinge 820. After separating the coconut meat from the coconut shell, it is turned upwards to facilitate the loading and unloading of the coconut. In the first embodiment, when the hand support 8 is fixedly connected to the frame 1 by bolts 810, it is not very convenient to load and unload the coconut.

[0070] Other structures of this embodiment are the same as those of the first embodiment.

[0071] Embodiment Four

[0072] As Figure 15 shown, in this embodiment, the thrust mechanism adopts the form of an electric cylinder and a spring composite thrust rod 630 (the electric cylinder can also be replaced with a pneumatic cylinder). The electric cylinder and the spring composite thrust rod 630 are arranged on the frame 1, and its telescopic end is connected to the slide plate 401 through a spring.

[0073] Before grooving, the electric cylinder of the electric cylinder and the spring composite thrust rod 630 pushes the piston rod to move to the rightmost side, and the slide plate 401 is pushed to move to the right by the spring 623 to ensure that the stop block 402 is always in contact with the bottom of the moving rod 5.

[0074] During the coconut grooving process, the electric reciprocating mechanism 520 drives the moving rod 5 to move to the right by a motor and a reducer. As the moving rod 5 moves to the right, the spring 623 pushes the slide plate 401 to move to the right accordingly, so that the cutter 301 cuts into the hard shell, thereby improving the automation degree of the equipment.

[0075] After grooving is completed, the electric cylinder of the electric cylinder and the spring composite thrust rod 630 pushes the piston rod to move to the leftmost side, and the slide plate 401 is pulled to move to the left to the corresponding position of the hand support by the convex head on the right side of the piston rod, positioning the slide plate 401, and thus eliminating the need for a locking device.

[0076] In addition, in order to protect the transmission belt 304 and prevent foreign objects from falling into it or human hands from accidentally touching the transmission belt, which may cause danger, a transmission belt guard 91 is provided outside the transmission belt 304 in this embodiment. To prevent debris from splashing during the coconut shell cutting process, a protective cover 92 is provided outside the cutting tool 301.

[0077] In this embodiment, since the bearing platform 203 can use a standardized self-centering three-jaw chuck, a chuck guard plate 93 is covered on the bearing platform 203 to prevent foreign objects from falling into the opening at the center of the chuck.

[0078] As Figure 16 shown, in this embodiment, a motor mounting plate 101 is provided on the frame 1, and both the cutting tool spindle 302 and the cutting tool motor 303 are mounted on the motor mounting plate 101.

[0079] The other structures of this embodiment are the same as those of Embodiment 1.

[0080] During the implementation of this device, the cutting tool assembly 3 can also be arranged on a movable plate that can move left and right, while the coconut 211 and the bearing platform 203 for loading the coconut only make a rotary motion, and the grooving of the coconut and the subsequent extraction of coconut eggs can also be realized.

[0081] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the present invention. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention all belong to the protection scope of the technical solution of the present invention.
