Detailed Description

Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is for purposes of illustration only and is not intended to limit the invention, its application, or uses.

FIG. 1 is a schematic perspective view of one embodiment of a punch assembly for a longan shelling and coring machine in accordance with the present invention; fig. 2 is an exploded schematic view of the apparatus of fig. 1, showing the parts exploded.

As shown in fig. 1, the punch device for a longan shelling and pitting machine according to an embodiment of the present invention includes: a kernel removing part 1, a fleshing part 2 and a driving part 3, wherein the driving part 3 is used for driving the kernel removing part 1 and the fleshing part 2 so as to enable the kernel removing part 1 and the fleshing part 2 of the punch device to carry out kernel removing operation and fleshing operation of longan.

As an embodiment, as shown in fig. 1, the coring portion 1 includes: a denucleation electric cylinder push rod 10, an upper punch 11, a bottom plate 12 and a spiral thimble 13, wherein the denucleation electric cylinder push rod 10 can comprise an electric cylinder and a push rod, and the electric cylinder can be actuated by the driving part 3 to enable the push rod 10 to move up and down. The push rod is detachably fixedly connected with the upper punch 11, and a compression spring 14 is arranged between the upper punch 11 and the bottom plate 12, and the compression spring is arranged in a certain compression state, for example, as an example, in one embodiment, the compression spring can be compressed by 4 mm. The upper portion of the screw spike 13 may be rotatably connected to the upper punch 11 by providing, for example, a screw pair, and the base plate 12 may be removably and fixedly connected to the middle portion of the screw spike 13, so that the screw spike is caused to rotatably push out the longan seeds during operation of the entire punch assembly. For example, as an embodiment, an internal thread is arranged in the upper punch 11, an external thread is arranged on the outer surface of the upper part of the spiral ejector pin 13, the bottom plate 12 is fixed on the middle part of the spiral ejector pin 13, and the kernel removing electric cylinder push rod 10 integrally moves downwards under the action of the driving part 3. After the electric cylinder is actuated by the driving part again, the push rod is made to move downwards, namely, the push rod moves downwards, so that the upper punch 11, the bottom plate 12 and the spiral ejector pin 13 are pushed to move downwards, when acting force is generated when the lower end of the spiral ejector pin 13 is contacted with longan and longan seeds, the action of the acting force is received, the external thread on the upper part of the spiral ejector pin 13 and the internal thread of the upper punch 11 move in a matched mode to drive the spiral ejector pin 13 to rotate upwards, meanwhile, the bottom plate 12 and the spiral ejector pin 13 are fixed, the action of the acting force is also received, the push rod continuously moves downwards, the compression spring 14 is further compressed, and therefore the spiral ejector pin 13 pushes out the longan seeds while rotating. Due to the push rod going downwards all the time, the further upward compression of the compression spring and the reaction force of the longan seed, the displacement of the spiral thimble 13 relative to the push rod 10 of the pitting cylinder or relative to the upper punch 11 is upward while the longan seed is pushed out, but the displacement of the whole pitting part 1 relative to the longan seed is downward. After the longan seeds are pushed out, the reaction force of the longan seeds disappears, the compression springs 14 rebound, and the spiral ejector pins 13 move downwards. At the moment, the electric cylinder is actuated to retract the push rod and restore the original position. For example, in one embodiment, the electric cylinder is capable of performing a push rod operation in response to forward rotation of a motor in the drive unit, and a retracting operation in response to reverse rotation of the motor. Whereby after completion of the coring, the electric cylinder retracts the push rod. However, the spiral pin rotates downward by itself while being moved upward by the push rod 10. For example, when the longan seed is pushed downwards, the spring is compressed, the spiral thimble moves upwards relative to the upper punch, after the longan seed is not pushed out, the reaction force disappears, the spring is reset, and the spiral thimble moves downwards relative to the upper punch and returns to the original position.

It can be understood that the spiral thimble 13 is pushed downwards by the push rod and is also subjected to the reaction force of the longan seed, and when the reaction force is greater than the downward pushing force, the external thread on the upper part of the spiral thimble 13 and the internal thread of the upper punch 11 are displaced, so that the spiral thimble is rotated. While spinning, the longan seeds were still pushed down further. In addition, the reaction force of the longan seeds and the downward pushing force of the push rod further compress the compression spring, so that the spiral ejector pin 13 moves upward relative to the push rod and completes the operation of pushing out the longan seeds.

Thereby, the screw ejector 13 can rotate upward to perform coring work. Thereafter, the spiral needle 13 is moved downward by the spring restoring force of the compression spring 14 to return to the original state. When the spiral ejector pin pushes out the longan seeds, the contact surface of the spiral ejector pin and the longan seeds is small and the spiral ejector pin and the longan seeds are in rotary contact, so that the breakage rate of the longan seeds is reduced. Further, preferably, the head 131 of the spiral thimble 13 is made of a silica gel material, which has flexibility and hardness, so that when the spiral thimble 13 pushes out the longan seeds downwards, the longan seeds are not punctured, and the breakage rate is further reduced.

As still another embodiment, as shown in fig. 1, the meat removing part 2 includes: a fleshing electric cylinder push rod 20 and a push head 21, wherein the fleshing electric cylinder push rod 20 also comprises an electric cylinder and a push rod. Like the electric cylinder push rod 10 for denucleation in the denucleation part 1, the electric cylinder push rod for fleshing can also comprise an electric cylinder and a push rod, wherein the electric cylinder is actuated by a motor of the driving part to make the fleshing part perform the fleshing operation. In addition, also similar to the electric pitter cylinder push rod 10 of the pitter 1, the electric fleshing cylinder push rod 20 and the push head 21 are detachably and fixedly connected together, so that the electric fleshing cylinder push rod 20 pushes the push head 21 downwards to push out the pulp of the pitted longan by the push head 21. The end 211 of the pushing head 21 is preferably also made of silica gel material, so as to reduce the breakage rate of the pulp and the loss of juice in the pulp when contacting the longan pulp.

As an embodiment, as shown in fig. 2, the driving part 3 may include a housing 31, a motor 32 disposed in the housing 31, and a crankshaft 33, wherein the crankshaft 33 is mounted in the housing by two bearings 34, and the motor 32 can drive the crankshaft 33 to rotate. The housing 31 includes a plurality of removably attached housing bezels 311. Further, a connecting rod 35 is provided below the crankshaft 33 to constitute a crankshaft link mechanism together with the connecting rod 35. As shown in the drawing, the connecting rod 35 is disposed outside the housing, and thus, the lower housing frame plate 311 has a large opening to achieve the connection of the crankshaft 33 with the connecting rod 35. For example, as one embodiment, the motor 32 drives a set of timing wheels 36 and a timing belt 37, which in turn drive the connected crankshaft 33. Further, the motor 32 may be controlled by a control system, such as an encoder, to enable rotation through 90 degrees in the forward direction and also through 90 degrees in the reverse direction, for example. For example, the crankshaft rotates 90 degrees with the motor synchronizing wheel to lower the coring and fleshing portions to perform the coring and fleshing operations.

In addition, as mentioned above, the electric cylinder in the kernel removing electric cylinder push rod and the meat removing electric cylinder push rod can be driven by the driving part. For example, as an embodiment, the electric motor 32 is used for actuation, or another electric motor (not shown in the figure) is further arranged in the driving part 32, and the electric cylinders are used for actuation, so that the electric cylinders of the two parts can respectively actuate push rods connected with the electric cylinders to carry out the kernel pushing and meat removing operations. When the whole device does not work, the crankshaft 33 rotates to drive the connecting rod 35 to retract, so that the punch head is partially retracted.

Further, as an embodiment, as shown in fig. 1, the driving part 3 is connected to the coring part 1 and the fleshing part 2 through the mounting connection part 4 to drive the coring part 1 and the fleshing part 2 to perform the work process. As an embodiment, the mounting connection portion 4 includes a mounting plate 41 and a connection member 42. As an embodiment, one end of the link 35 of the driving part 3 passes through the mounting plate 41 and is fixedly connected to the mounting plate 41 by a connection member 42 such as a nut. The electric cylinder push rod 10 for denucleation of the denucleation part 1 and the electric cylinder push rod 20 for fleshing part 2 are detachably fastened and connected to the lower surface of the mounting plate 41 by means of a connecting member such as a screw, respectively, whereby the driving part 3 drives the denucleation part 1 and the fleshing part 2 to move down by means of downward movement of the connecting rod 35 to perform corresponding operations.

In practical application, a conveyer belt is arranged below the punch device. The processed longans are first transported on a conveyor belt to a designated coring station. The motor actuates the crankshaft to rotate, the connecting rod 35 moves downwards, the coring part fixedly connected to the mounting plate moves downwards, the electric cylinder in the coring electric cylinder push rod is actuated by the driving part to enable the push rod to move downwards, and the spiral ejector pin moves downwards under the action of the push rod to contact longan and complete the coring procedure. The denucleated longan is conveyed to a fleshing station, and the next denucleated longan enters the denucleating station. Similarly, the pushing head 21 of the fleshing part moves downward by the pushing rod of the fleshing electric cylinder to push out the pulp of the longan after denucleation, thereby completing the fleshing process.
