In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] like Figure 1-10 As shown in the figure, the fully automatic jujube pitting machine with anti-residue features in this embodiment includes a frame 1, a loading bin 2 and a pitting chamber 3 on the frame 1, a pitting device 4 in the pitting chamber 3, and a conveying device 5 in the loading bin 2 to deliver the jujubes to the pitting chamber 3; the jujubes are stacked in the loading bin 2 and are delivered one by one to the pitting device 4 by the conveying device 5 for pitting.

[0031] The conveying device 5 includes two parallel conveying chains 51 and a first driving device for driving the two conveying chains 51 to rotate. Several support shafts 52 are arranged in parallel between the two conveying chains 51. The bottom of the loading bin 2 is provided with vertical grooves to cooperate with the support shafts 52. The first driving device is a motor (not shown in the figure). The motor drives the two conveying chains 51 to rotate, which drives the support shafts 52 to run in a cycle. A red date can be held between two adjacent support shafts 52 and sent to the pitting device 4, which facilitates the subsequent pitting of the red dates.

[0032] The core removal device 4 includes a central shaft 41 mounted on a frame 1 and a second drive device 42 that drives the central shaft 41 to rotate. A turntable 43 is mounted on the central shaft 41 in conjunction with a support shaft 52. Side plates 44 that can be attached to the sides of the support shaft 52 are mounted on both sides of the turntable 43. A left core removal mechanism 45 and a right core removal mechanism 46 are respectively mounted on the left and right sides of the turntable 43. The left core removal mechanism 45 includes a plurality of left ejector pins 451 arranged circumferentially on the central shaft 41. A left punch sleeve 452 is sleeved on the left ejector pin 451 and a first moving mechanism that drives the left punch sleeve 452 to move axially. The right punch mechanism 46 includes several right ejector pins 461 arranged circumferentially on the central shaft 41. A right punch sleeve 462 is fitted onto each right ejector pin 461, and a second moving mechanism drives the right punch sleeve 462 to move axially. Both side plates 44 are provided with through holes 441 for either the left punch sleeve 452 or the right punch sleeve 462 to pass through. The second driving device 42 is a motor that drives the central shaft 41 to rotate. The support shaft 52 rotates along the bottom of the outer ring of the turntable 43. The linear velocity of the outer ring of the turntable 43 is equal to the running speed of the support shaft 52, thereby allowing the left punch mechanism 45 and... The right-hand pitting mechanism 46 remains stationary relative to the jujube, allowing for uninterrupted pitting. After the jujube on the support shaft 52 is delivered between the two side plates 44, the first moving mechanism drives the left-hand punch 452 to move through the side plate 44 toward the jujube, and the second moving mechanism drives the right-hand punch 462 to move through the side plate 44 toward the jujube. The left-hand punch 452 and right-hand punch 462 are inserted into the jujube, together covering the pit. Then, the left-hand punch 452 and right-hand punch 462 move in opposite directions, carrying the pit out, and the left-hand punch 452 and right-hand punch 462 are removed. After the side plate 44 is closed, the left punch sleeve 452 retracts to the left ejector pin 451. When the date pit is left in the left punch sleeve 452, the left ejector pin 451 can push the date pit left in the left punch sleeve 452 off. Similarly, when the date pit is left in the right punch sleeve 462, the right ejector pin 461 can push the date pit left in the right punch sleeve 462 off, completing one pitting operation. Multiple sets of left ejector pins 451, left punch sleeves 452, right ejector pins 461, and right punch sleeves 462 are circumferentially arranged on the central shaft 41, so that the pitting operation can be performed for each date when the turntable 43 rotates and the support shaft 52 moves.

[0033] A leveling chamber 6 is provided on the frame 1 between the loading bin 2 and the pitting chamber 3. The bottom of the leveling chamber 6 is uphill. The support shaft 52 runs along the bottom surface of the leveling chamber 6. A horizontal leveling device and a vertical leveling device are provided in the leveling chamber 6. The horizontal leveling device includes a first support rod 61, on which a diagonal rod 62 is provided on one side of the support shaft 52. The diagonal rod 62 is inclined inward along the running direction of the support shaft 52. The vertical leveling device includes a second support rod 63, on which a diagonal plate 64 is provided. A brush is provided at the bottom of the diagonal plate 64. The support shaft 52 supports the red dates and conveys them upward through the leveling chamber 6. The red dates first pass through the horizontal leveling device, and then the diagonal rod 62... 2. Move the red dates to one side. If multiple red dates remain horizontally on the support shaft 52, the excess red dates can be squeezed off, leaving only one red date. Preferably, the inclined rod 62 can be fixed to the first support rod 61 by bolts. After loosening the bolts, the inclination of the inclined rod 62 can be adjusted to accommodate red dates of different sizes for horizontal squeezing. Then, the red dates pass upward through the vertical leveling device. If there are multiple red dates vertically, the brush on the inclined plate 64 is located on the upper side of the support shaft 52 and can push off the excess red dates. If the red dates are vertically stacked between the support shafts 52, the brush on the inclined plate 64 can also push the red dates horizontally to facilitate the subsequent pitting operation.

[0034] Preferably, the conveyor chain 51 is driven by a first rotating wheel 53, a second rotating wheel 54, and a third rotating wheel 55. The first rotating wheel 53 is located at the bottom of the loading hopper 2, and the second rotating wheel 54 and the third rotating wheel 55 are located in the pitting chamber 3. The central shaft 41 is located between the second rotating wheel 54 and the third rotating wheel 55. The conveyor chain 51 passes through the bottom of the turntable 43. The first driving device drives the first rotating wheel 53 to rotate, thereby driving the conveyor chain 51 to run as a whole. The support shaft 52 carries the red dates upward and moves them past the second rotating wheel 54. After the support shaft 52 and the red dates move to the bottom of the turntable 43, the red dates are pitted by the left pitting mechanism 45 and the right pitting mechanism 46.

[0035] Preferably, the first moving mechanism includes an arc-shaped first guide plate 453 disposed at the bottom of the central shaft 41, a first driving block 454 connected to the rear side of the left punch sleeve 452, a first roller 455 rotatably disposed on the first driving block 454, and a first guide groove 456 formed on the first guide plate 453 in conjunction with the first roller 455. When the central shaft 41 rotates, the first driving block 454, the left punch sleeve 452, and the left ejector pin 451 rotate synchronously. After the first driving block 454 rotates into the first guide groove 456, it will move along the direction of the first guide groove 456. In this embodiment, the first guide groove 456 is V-shaped. When the first driving block 454 rotates, it can drive the left punch sleeve 452 to move axially on the left ejector pin 451 for feeding and retraction. Multiple left punch sleeves 452 have first drive blocks 454 passing through first guide grooves 456 in sequence, so that the left punch sleeves 452 can perform punching actions in sequence. In this embodiment, two adjacent left punch sleeves 452 can share one first drive block 454. Two adjacent left punch sleeves 452 can perform de-core feeding and retraction actions at the same time, which can improve the stability of the first drive block 454 and prevent the first drive block 454 from rotating.

[0036] Preferably, the first driving block 454 is sleeved on the left ejector pin 451. The first driving block 454 and the left punch sleeve 452 are connected by the first elastic element 457, which is a spring. If the jujube pit is too large or the angle is not correct, the left punch sleeve 452 and the right punch sleeve 462 cannot completely cover the jujube pit. When the first driving block 454 drives the left punch sleeve 452 to feed, it hits the jujube pit and compresses the spring, avoiding hard punching and producing residual pit, thus ensuring food safety.

[0037] Preferably, the second moving mechanism includes an arc-shaped second guide plate 463 disposed at the bottom of the central shaft 41, a second driving block 464 connected to the rear side of the right punch sleeve 462, a second roller 465 rotatably disposed on the second driving block 464, and a second guide groove 466 formed on the second guide plate 463 in conjunction with the second roller 465. When the central shaft 41 rotates, the second driving block 464, the right punch sleeve 462, and the right ejector pin 461 rotate synchronously. After the second driving block 464 rotates into the second guide groove 466, it will move along the direction of the second guide groove 466 to realize the feeding and retraction actions. The second drive blocks 464 on the multiple right punch sleeves 462 pass through the second guide grooves 466 in sequence, so that the right punch sleeves 462 can perform punching actions in sequence. In this embodiment, two adjacent right punch sleeves 462 can share one second drive block 464. Two adjacent right punch sleeves 462 can perform de-core feeding and retraction actions at the same time, which can improve the stability of the second drive block 464 and prevent the second drive block 464 from rotating.

[0038] Preferably, a support plate 411 is provided on the central shaft 41 in conjunction with the right ejector pin 461. The right ejector pin 461 is axially movable on the support plate 411. A third moving mechanism is provided on the central shaft 41 to drive the right ejector pin 461 to move axially. A rubber ring 4410 is provided at the through hole 441. The right ejector pin 461 can also move axially. In this embodiment, the dropping of the date pit can only occur on the left side of the turntable 43, and the following situations and actions are defined:

[0039] like Figure 4 As shown, when the jujube pit is left in the left punch sleeve 452: the jujube pit follows the left punch sleeve 452 back until the left punch sleeve 452 backs to the left ejector pin 451 and pushes the jujube pit off. During this process, the right ejector pin 461 and the right punch sleeve 462 also move to the left to remove the perforation 441 of the left side plate 44. Then the right punch sleeve 462 stops moving, and the right ejector pin 461 continues to move to the left until it pushes out the right punch sleeve 462, making a hollow push action.

[0040] like Figure 5 , 6 As shown, when the jujube pit is left in the right punch sleeve 462: the left punch sleeve 452 retracts until the left ejector pin 451 pushes it out, the right punch sleeve 462 and the right ejector pin 461 also move to the left until they are removed from the perforation 441 of the left side plate 44, then the right punch sleeve 462 stops moving, and the right ejector pin 461 continues to move to the left until it pushes out the right punch sleeve 462, thus pushing the jujube pit left in the right punch sleeve 462 out.

[0041] When the left punch sleeve 452 and the right punch sleeve 462 fail to completely cover the date pit: the left punch sleeve 452 retracts to the left ejector pin 451 and pushes it out, the right punch sleeve 462 and the right ejector pin 461 also move to the left to the hole 441 of the left side plate 44, and the right punch sleeve 462 and the right ejector pin 461 together push the date pit out of the hole 441 of the left side plate 44 and it falls out; among them, the rubber ring 4410 at the hole 441 allows the date pit to pass through, and the rubber ring 4410 as a whole can block the date from moving out;

[0042] Preferably, the third moving mechanism includes an arc-shaped third guide plate 467 disposed at the bottom of the central shaft 41, a third drive block 468 connected to the rear side of the right ejector pin 461, a third roller 469 rotatably disposed on the third drive block 468, and a third guide groove 4610 formed on the third guide plate 467 in conjunction with the third roller 469. When the central shaft 41 rotates, the third drive block 468, the right punch sleeve 462, and the right ejector pin 461 rotate synchronously. After the third drive block 468 rotates into the third guide groove 4610, it will move along the direction of the third guide groove 4610 to realize the feeding and retraction actions. The third driving blocks 468 on the multiple right ejector pins 461 pass through the third guide groove 4610 in sequence, so that the right ejector pins 461 can perform ejection actions in sequence. In this embodiment, two adjacent right ejector pins 461 can share one third driving block 468, and two adjacent right ejector pins 461 can perform ejection and retraction actions at the same time, which can improve the stability of the third driving block 468 and prevent the third driving block 468 from rotating.

[0043] Preferably, a baffle wheel 65 and a third drive device for driving the baffle wheel 65 to rotate are provided on the lower side of the flat material cavity 6. Several baffles 651 are provided on the baffle wheel 65 along the circumference. A baffle brush 652 is provided on the baffle 651. An opening with the same width as the support shaft 52 is provided in the middle of the baffle brush 652. The third drive device is a motor (not shown in the figure). The motor drives the baffle wheel 65 to rotate. The baffle wheel 65 can block the pile of dates and prevent the whole pile from being sent upward with the support shaft 52. The opening in the middle of the baffle brush 652 allows the dates on the support shaft 52 to pass through.

[0044] Preferably, a plurality of top blocks 431 are arranged circumferentially on the turntable 43, the spacing between the top blocks 431 is equal to the spacing between the two support shafts 52, and a second elastic element 432 is provided between the top blocks 431 and the turntable 43. The turntable 43 clamps the red dates by cooperating with the support shafts 52 through the top blocks 431, which improves the stability during pitting, avoids hard squeezing of the red dates and pressing the red dates, and can also be used to fix red dates of different sizes.

[0045] Preferably, a discharge trough 7 is provided on the front side of the pitting chamber 3 on the frame 1, and a feeding wheel 8 and a fourth drive device 82 for driving the feeding wheel 8 to rotate are provided on the front side of the turntable 43 on the frame 1. A feeding brush 81 is provided on the feeding wheel 8 along the circumference. The fourth drive device 82 is a motor. The motor drives the feeding wheel 8 to rotate, which can make the feeding brush 81 brush on the surface of the turntable 43. When red dates stick to the turntable 43 or the top block 431, the feeding brush 81 can push the red dates off and collect them through the discharge trough 7.

[0046] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
