[0001] The present invention relates to the technical field of processing of removing the pits of Choerospondias axillaris, and particularly relates to a rotary multi-station Choerospondias axillaris pit pre-expanding and ejecting device. Background Art

[0002] Choerospondias axillaris is a characteristic plant fruit with edible, medicinal and industrial values. The fruit is mostly oval or obovate. When mature, the outer skin is golden or orange-red, smooth and shiny on the surface. After pre-boiling, the viscosity of the pulp of Choerospondias axillaris will increase significantly, and the pulp becomes thicker. During the processing, it even adheres to the utensils and is difficult to separate.

[0003] In the prior art, due to the characteristics of thick and tough skin and high viscosity of the pulp of Choerospondias axillaris, the separation of the pulp and the pit of Choerospondias axillaris mostly relies on manual operation.

[0021] It further includes a pretreatment unit 3. The pretreatment unit 3 includes a loading table 30. A cracker 301 is fixedly connected to the bottom of the inner wall of the loading table 30. A support frame 31 is provided above the turntable 11. The lower surface of the support frame 31 is slidably connected to a top plate 32 through an electric slide rail. The top plate 32 is connected to a connecting plate 34 through a push rod 33 provided on its lower surface. A peeling structure 35 is provided on the lower surface of the connecting plate 34. An aperture expanding member 36 is provided on one side of the inner baffle 122 away from the turntable 11.

[0022] A driving seat for driving connection with the outer end of the main shaft 211 is provided inside the turntable 11. A die hole 1211 is formed inside the outer baffle 121. A scraping ring 217 is fixedly connected to the circumferential inner wall of the die hole 1211.

[0023] The peeling structure 35 includes side plates 351 fixedly connected to the lower surface of the top plate 32. The side plates 351 are slidably connected to a clamping plate 352 and a connecting frame 353 through T-shaped grooves 3511 formed inside them. Two clamping plates 352 are provided and are symmetrically arranged on both sides of the connecting frame 353. A connecting rod 354 rotatably connected to the outer end of the clamping plate 352 is rotatably connected to the outside of the connecting frame 353. The upper surface of the connecting frame 353 is fixedly connected to the lower surface of the connecting plate 34. Two side plates 351 are provided and are symmetrically distributed on both sides of the connecting frame 353. Multiple groups of peeling structures 35 are arranged in an array.

[0024] The side plate 351 is slidably connected to a connecting shaft 355 through a chute 3512 formed inside it. Two chutes 3512 are provided and are symmetrically distributed on both sides of the T-shaped groove 3511. A connecting hook 356 that fits the outer surface of the connecting shaft 355 is fixedly connected to one side of the clamping plate 352 close to the side plate 351. A roller 357 is rotatably connected to the circumferential outer surface of the connecting shaft 355.

[0025] The outer end of the connecting shaft 355 penetrates through the chute 3512 and is fixedly connected to a magnetic block 358. The lower surface of the clamping plate 352 is designed with an arc surface.

[0026] The inner baffle 122 is fixedly connected to the upper surface of the outer baffle 121 through a special-shaped block fixed on its upper surface. A connecting plate 123 is fixedly connected to the upper surface of the inner baffle 122. A lifting platform 124 is arranged in the middle of the turntable 11, and the upper surface of the lifting platform 124 is connected to the lower surface of the connecting plate 123.

[0027] On one side of the lower ends of the inner baffle 122 and the outer baffle 121 close to the turntable 11, a conical surface design is adopted.

[0028] This device is divided into four working stations: feeding, hole expanding, core removing, and scraping. The peeling structure 35, the hole-expanding part 36, and the ejecting part 21 are arranged in sequence along the rotation direction of the turntable 11. The turntable 11 rotates intermittently. A plurality of placement grooves 111 are opened on each working station of the turntable 11, which can simultaneously accommodate a plurality of wild jujubes for processing. Multiple wild jujubes can be processed simultaneously at the four working stations.

[0029] The process of preprocessing the wild jujube before core removal: In practical applications, a plurality of wild jujubes that have been pre-boiled and sized by screening are neatly stacked above the feeding table 30 and gradually approach the rotating part 1 through the feeding table 30. A cracker 301 (the cracker 301 adopts a slender and sharp design, with a sharper side away from the rotating part 1) is fixedly connected to the bottom end of the inner wall of the feeding table 30 close to the rotating part 1. The top plate 32 is slidably connected to the lower surface of the support frame 31 through an electric slide rail. The outer ends of the connecting frame 353 and the clamping plate 352 are both slidably connected inside the T-shaped groove 3511 through sliding buttons. Initially, the top plate 32 is on the side away from the lifting platform 124 within its stroke range, and the push rod 33 is in the unfolded state. The T-shaped groove 3511 is divided into two parts: a horizontal section and a vertical section. The outer end of the connecting frame 353 is at the bottom of the vertical section inside the T-shaped groove 3511, while the outer end of the clamping plate 352 is outside the horizontal section of the T-shaped groove 3511, and the connecting rod 354 fixedly connected to the outer ends of the clamping plate 352 and the connecting frame 353 is in a horizontal state.

[0030] When the Chinese hawthorns are transported to the outer end of the loading platform 30 near the rotating portion 1, they are stacked horizontally. The lower portion of the outer surface of the Chinese hawthorns passes through the breaker 301, resulting in a notch on the bottom. The highest point of the outer circumference of the Chinese hawthorns is higher than the upper surface of the loading platform 30, and the highest point of the outer circumference of the Chinese hawthorns is higher than the lowest point of the bottom end of the clamping plate 352. The push rod 33 starts to rise, driving the connecting plate 34 and the connecting frame 353 to move upward. The sliding buckle at the outer end of the connecting frame 353 is located on the lower surface of the vertical section of the T-slot 3511 and also moves upward synchronously. Because the outer ends of the clamping plate 352 and the connecting frame 353 are rotatably connected by the connecting rod 354, when the connecting frame 353 is raised, the connecting rod 354 gradually transforms into an inclined state (the side near the connecting frame 353 is higher, and the side near the clamping plate 352 is lower). Under the pulling action of the connecting rod 354, the clamping plate 352 slides and connects inside the horizontal section of the T-slot 3511 via the sliding buckle.

[0031] Correspondingly, the connecting shafts 355 on both sides, under the action of the connecting hooks 356, are positioned within the chute 3512 and move toward each other. The distance between the two side clamps 352 gradually shortens until their adjacent surfaces clamp the outer circumferential surface of the Chinese jujube fruit near the upper position (the pulp of the Chinese jujube fruit is very sticky, and even with the presence of a slider at the bottom, the pulp and peel will not separate after being clamped). The magnetic blocks 358 on the outer ends of the connecting shafts 355 on both sides have not yet been attached. Under the action of magnetic force, the outer circumferential surface of the roller 357 is tightly attached to the outer surface of the clamp 352. In this state, the connecting rod 354 is in a vertical state. The slider at the outer end of the clamp 352 adopts a design with adjacent surfaces being flat. After the adjacent surfaces are tightly attached, they are located at the bottom end of the vertical section of the T-slot 3511. The slider at the outer end of the connecting frame 353 is located in the middle and upper part of the vertical section of the T-slot 3511.

[0032] The electric slide rails on the lower surface of the support frame 31 drive the top plate 32 toward the turntable 11 and align it with the placement slot 111 on the upper surface of the turntable 11. As the push rod 33 continues to move upward, the clamping plates 352, under the action of the vertical sections of the T-slots 3511, drive the still-clamped jujube peel upward. The connecting shafts 355 on either side, located within the slide slots 3512, are attracted to each other by the magnetic blocks 358 at their outer ends, exerting a constant squeezing force toward the center. The relative positions of the connecting shafts 355 and rollers 357 remain unchanged until the clamping plates 352 move upward. Once the outer surfaces of the clamping plates 352 break contact with the outer surfaces of the rollers 357, the magnetic blocks 358 on either side instantly engage. As the push rod 33 continues to move upward, the rollers 357 and clamping plates 352 generate relative motion. Under the action of the two rollers 357, the fruit pulp is forced out of the notch at the bottom, and the peeled core and flesh fall into the placement slot 111. At this time, the peel is still clamped by the two clamping plates 352, and the top plate 32 continues to move under the drive of the electric slide rail, and the peeling structure 35 unloads the peel at the peel unloading position.

[0033] The lifting table 124 starts, driving the connecting plate 123, the outer baffle 121, and the inner baffle 122 to rise synchronously, disengaging from the outer surface of the turntable 11. The turntable 11 starts intermittently, driving the peeled Choerospondias axillaris in the placement groove 111 into the next reaming process. The lifting table 124 drives the lifting member 12 to descend again. Among them, the bottom ends of the sides of the outer baffle 121 and the inner baffle 122 close to the turntable 11 are designed in a conical shape, and the connection between the outer surfaces of the outer baffle 121 and the inner baffle 122 is designed with a curved surface, which not only plays a guiding role but also can play a correcting role during each conversion of the working position, avoiding errors caused by long-term use. The reaming member 36 is composed of multiple scrapers that fit the arc-shaped end faces of the Choerospondias axillaris, separating the pulp and the fruit core of the arc-shaped part at the outer end of the Choerospondias axillaris, facilitating the next step of pit removal operation.

[0034] The process of separating the pit and the pulp of the Choerospondias axillaris: The lifting table 124 starts again, driving the connecting plate 123, the outer baffle 121, and the inner baffle 122 to rise synchronously, disengaging from the outer surface of the turntable 11, and driving the reamed Choerospondias axillaris in the placement groove 111 into the next pit removal process.

[0035] The ejecting member 21 is on one side of the inner baffle 122. After the lifting member 12 is restored, the driving seat drives the main shaft 211 to move towards the placement groove 111. In the initial state, the spring 215 is in an expanded state, the distance between the connecting ring 214 and the fixed ring 216 is relatively far, and a concave shape is formed between the multiple scraping rods 212, which fits the convex outer end of the Choerospondias axillaris. The convexity of the Choerospondias axillaris corresponds to the concavity formed by the multiple scraping rods 212. When the end of the main shaft 211 fits the outer surface of the Choerospondias axillaris, the main shaft 211 drives the Choerospondias axillaris to move towards the scraper ring 217 together. If the central axis of the pit of the Choerospondias axillaris does not coincide with the axis of the main shaft 211, the multiple scraping rods 212 distributed in a circumferential array can correct the position of the Choerospondias axillaris during the movement. At this time, the included angle formed by the scraping rod 212 and the long rod 213 is an acute angle, and the connection between the two points to the position where the scraper ring 217 is located. As the main shaft 211 gradually moves towards the position where the scraper ring 217 is located, the pit of the Choerospondias axillaris enters the scraper ring 217 on the inner circumferential wall of the die hole 1211. The scraper ring 217 is preferably made of silica gel material, which has a certain elasticity and can adapt to Choerospondias axillaris with different diameters within a certain range.

[0036] The wild jujube pits gradually pass through the inner wall of the circumference of the scraping ring 217. After passing through the die holes 1211, the wild jujube pits are ejected by the main shaft 211, and the remaining pulp is retained by the scraping ring 217 in the placement groove 111 and on the side of the outer baffle 121 close to the placement groove 111. At the moment when the wild jujube pits are ejected, the outer end of the main shaft 211 penetrates through the die holes 1211. When the end of the scraping rod 212 far from the main shaft 211 contacts the surface of the outer baffle 121, it acts as a barrier. The position of the connecting ring 214 is relatively stationary. When the main shaft 211 and the fixing ring 216 continue to move forward, the distance between the fixing ring 216 and the connecting ring 214 decreases, and the spring 215 is compressed and undergoes elastic deformation. After the separation action of the wild jujube pits and the pulp is completed, the main shaft 211 retreats backward a certain distance to make the scraping rod 212 in a state parallel to the outer surface of the main shaft 211 (when the scraping rod 212 is parallel to the outer end of the main shaft 211, the circumferential radius formed by multiple scraping rods 212 is equal to the circumferential radius of the arc section at the bottom of the placement groove 111, and the radius of the circle formed by multiple scraping rods 212 is greater than the radius of the die holes 1211). At this time, the outer surface of the scraping rod 212 is closely attached to the outer surface of the outer baffle 121. The internal drive of the drive seat rotates the main shaft 211, and the scraping rod 212 scrapes the remaining pulp around the die holes 1211 of the outer baffle 121 to separate it from the outer baffle 121. The main shaft 211 retreats. During this process, the scraping rod 212 loses the block, and the connecting ring 214 quickly recovers under the action of the spring 215. A container for receiving the dripping pulp is also placed between the drive seat and the inner baffle 122.

[0037] The lifting platform 124 continues to start, driving the connecting plate 123, the outer baffle 121, and the inner baffle 122 to rise synchronously, disengaging from the outer surface of the turntable 11, driving the remaining wild jujube pulp inside the placement groove 111 into the next scraping and discharging process, and scraping the pulp inside the placement groove 111. The outer surfaces of the turntable 11 and the placement groove 111, etc. are all made of stainless steel, with smooth surfaces and easy to clean. So far, a complete process of removing the wild jujube pits has been completed.

[0038] To sum up, the equipment has the following advantages in the process of removing the wild jujube pits: Advantage 1: Through the placement groove 111 on the turntable 11, the wild jujubes are driven through four workstations of feeding, hole expansion, pit removal, and scraping, realizing automated continuous operation, being able to quickly complete the pit removal process, further improving production efficiency, reducing manual operation, and lowering labor intensity.

[0039] Advantage 2: In the pretreatment section 3, non-destructive peeling is completed by the cooperation of the magnetic blocks 358 and the rollers 357, which not only ensures the integrity of the pulp but also avoids the error of manual sorting. When the clamping plates 352 on both sides move towards each other through the sliding buckles in the horizontal section of the T-shaped groove 3511, the outer surface of the Choerospondias axillaris peel is clamped. When the clamping plates 352 on both sides move upward synchronously through the sliding buckles in the vertical section of the T-shaped groove 3511, the clamping plates 352 are separated from the rollers 357 in the vertical direction. Under the action of the magnetic blocks 358, the two rollers 357 and the connecting shaft 355 quickly approach, forming a squeezing situation for the Choerospondias axillaris pulp at the bottom. The two magnetic blocks 358 are attracted to each other (the magnetic force can finely adjust the clamping force to adapt to the difference in the peel toughness of fruits with different maturities and improve the separation reliability). The outer surfaces of the two rollers 357 are not completely fitted, and the rollers 357 can rotate freely on the outer surface of the connecting shaft 355. When the clamping plates 352 clamp the peel and rise, while the rollers 357 are fixed at the central position due to magnetic attraction, a shear force is generated between the peel and the pulp. The pre-existing cut at the bottom of the Choerospondias axillaris (formed by the pretreatment during feeding on the feeding table 30) opens under the extrusion of the rollers 357, and the pulp is forced to be extruded from the cut due to its flexible characteristics, while the peel is still clamped by the clamping plates 352 (the peel has high toughness and is not easily broken). The outer surface of the roller 357 is smooth and can rotate freely, reducing the friction during extrusion, avoiding pulp retention or damage, and having a high extrusion rate of the pulp.

[0040] Advantage 3: Although the turntable 11 uses intermittent transmission, if mechanical wear occurs during long-term use (such as an increase in the clearance between the shaft hole), it may cause a circumferential position deviation or a radial offset after the placement groove 111 rotates in place. When the lifting member 12 descends, the tapered guide surfaces at the bottom ends of the outer baffle 121 and the inner baffle 122 first contact the outer surface of the turntable 11 until the outer surface of the turntable 11 is fitted with the outer baffle 121 and the inner baffle 122. After descending, the arc surfaces of the outer baffle 121 and the inner baffle 122 are completely fitted with the surface of the turntable 11. By means of surface constraint, the clearance is eliminated, ensuring accurate positioning during the station conversion. The lifting member 12 can change from passively accepting the deviation to actively correcting the deviation, establishing an accuracy closed-loop in the processing process, realizing a complex dynamic positioning function with a simple mechanical structure, and balancing the requirements of cost, reliability, and accuracy; providing a benchmark guarantee for subsequent processes such as pitting and scraping, ensuring that the grooves opened on the upper surfaces of the outer baffle 121 and the inner baffle 122 are connected to the placement groove 111, and further ensuring the stable operation and processing of the equipment.

[0041] Advantage 4. Since the pulp of the Choerospondias axillaris has a certain viscosity, after the pit removal is completed, the remaining pulp will adhere to the surface of the outer baffle 121 around the die hole 1211. If the lifting member 12 is directly lifted, after the lower surface of the pulp loses the supporting effect of the placement groove 111, it will slide down due to gravity and fall between the outer baffle 121 and the turntable 11, which is not conducive to cleaning. During the ejection process of the ejector member 21, in addition to further ensuring that the central axis of the Choerospondias axillaris pit coincides with the central axis of the die hole 1211 (the central axis of the die hole 1211 and the central axis of the main shaft 211), being compatible with Choerospondias axillaris of different diameters within a certain range, correcting the posture of the Choerospondias axillaris before ejection, and correcting the eccentricity of the Choerospondias axillaris, it can also scrape the pulp adhering to the surface of the outer baffle 121 around the die hole 1211 after the pit is ejected, avoiding accumulation and reducing the risk of microbial contamination.
