Description

Technical Field

[0001] The invention relates to the technical field of sorrel jujube pitting processing, and in particular to a rotary disc type multi-station sorrel jujube pit pre-expansion and ejection device. Background Art

[0002] The fruit of the Chinese jujube is a special plant with edible, medicinal and industrial value. The fruit is mostly oval or obovate. When ripe, the skin is golden or orange-red, and the surface is smooth and shiny. After the Chinese jujube is pre-cooked, the viscosity of the flesh will increase significantly, and the flesh will become thicker. During processing, it may even stick to the utensils and be difficult to separate.

[0003] In the existing technology, due to the characteristics of thick, tough and hard skin and high viscosity of the Chinese jujube, the separation of the pulp and the core of the Chinese jujube mostly relies on manual operation. Manual separation is inefficient and labor-intensive, making it difficult to meet the needs of large-scale industrial production. Manual operation is easily affected by subjective factors, resulting in unstable quality of core-to-flesh separation, high pulp breakage rate, and serious waste of raw materials. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the prior art, the present invention provides a turntable-type multi-station pre-expansion and ejection device for the core pores of sorrel (Zoara jujube), which can effectively solve the problems in the prior art that due to the characteristics of sorrel (Zoara jujube) such as thick, tough and hard skin and high viscosity of the flesh, the separation of the flesh and core of sorrel mostly relies on manual operation, the manual separation efficiency is low, the labor intensity is high, and it is difficult to meet the needs of large-scale industrial production. In addition, manual operation is easily affected by subjective factors, resulting in unstable core-meat separation quality, high flesh breakage rate, and serious waste of raw materials.

[0011] Furthermore, a driving seat for transmission connection with the outer end of the main shaft is provided on the inner side of the turntable, a die hole is opened inside the outer baffle, and a scraper ring is fixedly connected to the circumferential inner wall of the die hole.

[0012] Furthermore, the peeling structure includes a side plate fixedly connected to the lower surface of the top plate, and the side plate is slidably connected to a splint and a connecting frame through a T-slot opened inside the side plate. The splint is provided with two symmetrical parts on both sides of the connecting frame.

The upper surface of the connecting frame is fixedly connected to the lower surface of the connecting plate. The side plates are provided with two and are symmetrically distributed on both sides of the connecting frame. The peeling structure array is provided with multiple groups.

[0013] Furthermore, the side plate is slidably connected to the connecting shaft through a slide groove opened inside it, and two slide grooves are provided and symmetrically distributed on both sides of the T-slot.

After passing through the reaming station, the flesh with the core enters the subsequent core removal station with the turntable. The main shaft of the ejector pushes the Chinese jujube to move toward the scraper ring. The elastic design of the scraper ring can adapt to different fruit core sizes. When the main shaft ejects the fruit core, the remaining flesh is blocked by the scraper ring to ensure that the core and flesh are completely separated.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example:

[0033] See also Figures 1-9 The present invention provides a technical solution: a rotary disc multi-station jujube seed hole pre-expansion and ejection device, comprising:

[0034] The rotating part 1 includes a turntable 11, a lifting member 12 is provided on the outside of the turntable 11, and a placement groove 111 for placing external southern jujubes is opened on the upper surface of the turntable 11;

[0035] The core removal part 2 includes an ejector 21 arranged on the inner side of the turntable 11. The lifting part 12 includes an outer baffle 121 and an inner baffle 122.

[0036] Among them, the ejector 21 includes a main shaft 211, and the outer end of the main shaft 211 close to the placement groove 111 is rotatably connected to the scraper rod 212. A plurality of scraper rods 212 are provided and distributed in a circular array along the outer surface of the main shaft 211. The end of the scraper rod 212 away from the main shaft 211 is rotatably connected to a long rod 213, and the outer end of the long rod 213 is rotatably connected to a connecting ring 214 sleeved on the outer surface of the circumference of the main shaft 211.

[0037] It also includes a pretreatment part 3, which includes a loading platform 30, a breaker 301 is fixedly connected to the bottom of the inner wall of the loading platform 30, a support frame 31 is arranged above the turntable 11, and the lower surface of the support frame 31 is slidably connected to a top plate 32 through an electric slide rail, and the top plate 32 is connected to a connecting plate 34 through a push rod 33 arranged on its lower surface, and a peeling structure 35 is arranged on the lower surface of the connecting plate 34, and a hole expansion part 36 is arranged on the side of the inner baffle 122 away from the turntable 11.

[0038] A driving seat for transmission connection with the outer end of the main shaft 211 is provided on the inner side of the turntable 11 . A die hole 1211 is opened inside the outer baffle 121 , and a scraper ring 217 is fixedly connected to the circumferential inner wall of the die hole 1211 .

[0039] The peeling structure 35 includes a side plate 351 fixedly connected to the lower surface of the top plate 32. The side plate 351 is slidingly connected to the splint 352 and the connecting frame 353 through a T-slot 3511 opened inside it. The splint 352 is provided with two symmetrical parts on both sides of the connecting frame 353. The outer side of the connecting frame 353 is rotatably connected to a connecting rod 354 rotatably connected to the outer end of the splint 352. The upper surface of the connecting frame 353 is fixedly connected to the lower surface of the connecting plate 34. There are two side plates 351 and they are symmetrically distributed on both sides of the connecting frame 353. The peeling structure 35 array is provided with multiple groups.

[0040] The side plate 351 is slidably connected to the connecting shaft 355 through a sliding groove 3512 opened inside it. There are two sliding grooves 3512 and they are symmetrically distributed on both sides of the T-slot 3511. The side of the splint 352 close to the side plate 351 is fixedly connected to a connecting hook 356 that fits the outer surface of the connecting shaft 355. The circumferential outer surface of the connecting shaft 355 is rotatably connected to a roller 357.

[0041] The outer end of the connecting shaft 355 passes through the sliding groove 3512 and is fixedly connected to the magnetic block 358 . The lower surface of the clamping plate 352 adopts a curved surface design.

[0042] 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. The upper surface of the inner baffle 122 is fixedly connected to a connecting plate 123. A lifting platform 124 is provided in the middle of the turntable table 11. The upper surface of the lifting platform 124 is connected to the lower surface of the connecting plate 123.

[0043] The lower ends of the inner baffle 122 and the outer baffle 121 close to the turntable 11 are both designed with a conical surface.

[0044] This equipment is divided into four workstations: loading, reaming, core removal and scraping. The peeling structure 35, the reaming part 36 and the ejector 21 are arranged in sequence along the rotation direction of the turntable 11. The turntable 11 adopts intermittent rotation. Each workstation on the turntable 11 is provided with multiple placement slots 111, which can simultaneously accommodate multiple Chinese jujubes for processing. The four workstations can process multiple Chinese jujubes at the same time.

[0045] The process of pre-treatment of sour jujube before pitting:

[0046] In practice, multiple pre-cooked and sized Chinese jujubes are neatly stacked on top of the loading platform 30, gradually approaching the rotating unit 1 through the loading platform 30. A breaker 301 is fixedly attached to the inner wall of the loading platform 30, near the bottom of the rotating unit 1 (the breaker 301 adopts a slender, sharp design, with a sharper point on the side away from the rotating unit 1). The top plate 32 is slidably connected to the lower surface of the support frame 31 via an electric slide rail. The outer ends of the connecting frame 353 and the clamping plate 352 are slidably connected within the T-slot 3511 via a sliding buckle. Initially, the top plate 32 is within its travel range, away from the lifting platform 124, and the push rod 33 is in the extended state. The T-slot 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-slot 3511, and the outer end of the splint 352 is at the outside of the horizontal section of the T-slot 3511. The connecting rod 354 fixedly connected to the outer end of the splint 352 and the connecting frame 353 is in a horizontal state.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] The lifting platform 124 starts, driving the connecting plate 123, the outer baffle 121, and the inner baffle 122 to rise synchronously and disengage from the outer surface of the turntable 11. The turntable 11 starts intermittently, driving the peeled Chinese hawthorn inside the placement groove 111 to enter the next hole enlarging process. The lifting platform 124 drives the lifting member 12 to recover downward again, wherein the bottom end of the outer baffle 121 and the inner baffle 122 close to the turntable 11 adopts a conical design, and the outer surface connection of the outer baffle 121 and the inner baffle 122 adopts an arc surface design, which plays a guiding role and can also play a correction role every time the work station is changed, avoiding errors caused by long-term use. The hole enlarging member 36 is composed of a plurality of scrapers that fit with the arc end face of the Chinese hawthorn, separating the pulp and the core of the arc surface part of the outer end of the Chinese hawthorn, so as to facilitate the next step of the core removal operation.

[0051] The process of separating the core and pulp of southern jujube:

[0052] The lifting platform 124 is started 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 sour jujube after the hole is expanded inside the placement groove 111 to enter the next de-core process.

[0053] The ejector 21 is on one side of the inner baffle 122. After the lifting member 12 is restored, the drive seat drives the main shaft 211 to move toward the placement groove 111. In the initial state, the spring 215 is in the expanded state, the distance between the connecting ring 214 and the fixing ring 216 is relatively far, and a concave shape is formed between the multiple scrapers 212, which fits with the outer end of the protrusion of the Chinese jujube. The protrusion of the Chinese jujube corresponds to the concave formed by the multiple scrapers 212. When the end of the main shaft 211 fits with the outer surface of the Chinese jujube, the main shaft 211 drives the Chinese jujube to move toward the scraper ring 217. If the central axis of the Chinese jujube kernel does not coincide with the axis of the main shaft 211, the multiple scrapers 212 distributed in a circular array can correct the position of the Chinese jujube during the movement. At this time, the angle formed by the scraper rod 212 and the long rod 213 is an acute angle, and the connection between the two points to the position of the scraper ring 217. As the main shaft 211 gradually moves toward the position of the scraper ring 217, the jujube kernel of the Chinese jujube enters the scraper ring 217 on the inner wall of the mold hole 1211. The scraper ring 217 is preferably made of silicone and has a certain elasticity, which can adapt to Chinese jujubes with different diameters within a certain range.

[0054] The Chinese jujube kernel gradually passes along the inner circumference of the scraper ring 217, and after passing through the die hole 1211, it is ejected by the main shaft 211. The remaining fruit pulp is retained by the scraper ring 217 in the placement groove 111 and on the side of the outer baffle 121 near the placement groove 111. At the moment the kernel is ejected, the outer end of the main shaft 211 penetrates the die hole 1211, and the end of the scraper 212 away from the main shaft 211 contacts the surface of the outer baffle 121 to block it. The position of the connecting ring 214 is relatively static. As the main shaft 211 and the fixed ring 216 continue to move forward, the distance between the fixed ring 216 and the connecting ring 214 decreases, and the spring 215 is compressed and elastically deformed. After separating the core from the pulp, the spindle 211 retracts a certain distance, placing the scraper rods 212 parallel to the outer surface of the spindle 211 (when the scraper rods 212 are parallel to the outer ends of the spindle 211, the radius of the circle formed by the multiple scraper rods 212 is equal to the radius of the arc-shaped section at the bottom of the placement groove 111, and the radius of the circle formed by the multiple scraper rods 212 is greater than the radius of the mold hole 1211). At this point, the outer surface of the scraper rods 212 is in close contact with the outer surface of the outer baffle 121. The internal drive spindle 211 of the drive base rotates, and the scraper rods 212 scrape the remaining pulp around the mold hole 1211 of the outer baffle 121, separating it from the outer baffle 121. The spindle 211 retracts, and during this process, the scraper rods 212 are unblocked, and the connecting ring 214 quickly recovers under the action of the spring 215. A container for catching dripping pulp is also placed between the drive base and the inner baffle 122.

[0055] 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, and driving the remaining Chinese jujube pulp inside the placement tank 111 to enter the next scraping and unloading process, scraping the pulp inside the placement tank 111. The outer surfaces of the turntable 11 and the placement tank 111 are all made of stainless steel, with a smooth surface and easy to clean. At this point, the entire process of removing the Chinese jujube core has been completed.

[0056] In summary, this equipment has the following advantages in the process of removing fruit cores:

[0057] Advantage 1: The placement slot 111 on the turntable 11 drives the southern jujube to perform four workstations of loading, reaming, removing the core and scraping, realizing automated continuous operation, and can quickly complete the removing process, further improving production efficiency, reducing manual operation and reducing labor intensity.

[0058] Advantage 2: In pre-processing section 3, magnetic blocks 358 and rollers 357 cooperate to achieve non-destructive peeling, ensuring fruit integrity while avoiding manual sorting errors. The two clamping plates 352 slide toward each other in the horizontal section of the T-slot 3511, clamping the outer surface of the Chinese jujube peel. When the two clamping plates 352 simultaneously move upward in the vertical section of the T-slot 3511, the clamping plates 352 and rollers 357 separate vertically. The two rollers 357 and the connecting shaft 355 rapidly approach each other under the influence of the magnetic blocks 358, squeezing the Chinese jujube fruit at the bottom. The two magnetic blocks 358 engage (magnetic force fine-tunes the clamping force to accommodate the varying toughness of the peels of fruits at different maturity levels, improving separation reliability). The outer surfaces of the two rollers 357 do not fully adhere to each other, allowing them to rotate freely on the outer surface of the connecting shaft 355. As clamping plates 352 lift the peel, while rollers 357 are magnetically fixed to the center, shear forces are generated between the peel and the flesh. The pre-existing notch on the base of the Chinese jujube (formed during pretreatment during transport from the loading platform 30) opens under the pressure of rollers 357. Due to its flexible nature, the flesh is forced out through the notch, while the peel remains clamped by clamping plates 352 (the peel is highly resilient and not prone to breakage). The smooth, freely rotating outer surface of rollers 357 reduces friction during extrusion, preventing flesh from being trapped or damaged, and achieving a high pulp extrusion rate.

[0059] Advantage 3: Although the turntable 11 adopts intermittent transmission, if long-term use causes mechanical wear (such as increased shaft hole clearance), the placement groove 111 may have circumferential position deviation or radial offset after it is rotated into 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 engaged with the outer baffle 121 and the inner baffle 122. After descending, the arc surface of the outer baffle 121 and the inner baffle 122 are completely in contact with the surface of the turntable 11, and the gap is eliminated through the curved surface constraint to ensure accurate position during work station conversion. The lifting member 12 can switch from passively accepting deviations to actively correcting deviations, establishing a precision closed loop for the machining process, realizing complex dynamic positioning functions with a simple mechanical structure, and balancing cost, reliability and precision requirements; providing a benchmark guarantee for subsequent processes such as core removal 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, thereby ensuring stable operation and machining of the equipment.

[0060] Advantage 4: Since the pulp of the Chinese jujube has a certain viscosity, after the core is removed, the remaining pulp will adhere to the surface of the outer baffle 121 around the mold hole 1211. If the lifting part 12 is directly raised, the lower surface of the pulp will lose the supporting effect of the placement groove 111 and 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, the scraper 212 in the ejector 21 can not only further ensure that the central axis of the Chinese jujube core coincides with the central axis of the mold hole 1211 (the central axis of the mold hole 1211 and the central axis of the main shaft 211), but also be compatible with Chinese jujubes of different diameters within a certain range, correct the posture of the Chinese jujube before ejection, and correct the eccentricity of the Chinese jujube. After the core is ejected, the pulp adhering to the surface of the outer baffle 121 around the mold hole 1211 can be scraped off to avoid accumulation and reduce the risk of microbial contamination.
