Description

Technical Field

[0001] This utility model belongs to the field of ready-to-eat kiwi fruit sorting technology, and in particular relates to an automatic sorting device for ready-to-eat kiwi fruit. Background Technology

[0002] Ready-to-eat kiwifruit refers to kiwifruit that has reached an edible state and can be consumed immediately after purchase. Through scientific management and advanced processing technology, it promotes starch conversion and delays pectin degradation, achieving excellent taste while maintaining a certain firmness and shelf life. Consumers do not need to wait for it to ripen after purchase.

[0003] Existing automated kiwi sorting equipment mostly uses a single physical parameter. If grading is done by weight or size, it cannot accurately identify the ripeness and edibility of kiwis. This results in a mixture of firmness and softness after sorting, and some fruits that do not meet the ready-to-eat standard are misclassified. This directly affects the quality control in the commodity circulation process. The sorted fruits still have problems such as large differences in firmness and softness and inconsistent ready-to-eat window, which directly affect the quality stability of the commodity in the circulation process and the consumer experience, making it unsuitable for use.

[0004] To address these issues, we provide an automated sorting device for ready-to-eat kiwifruit. Utility Model Content

[0005] The purpose of this invention is to provide an automatic sorting device for ready-to-eat kiwifruit, which combines a maturity detection component and a buffer protection component to solve the problem that existing automatic kiwifruit sorting devices lack maturity detection functionality, leading to large differences in fruit firmness and inconsistent ready-to-eat window periods after sorting.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an automatic sorting device for ready-to-eat kiwifruit, comprising a conveyor frame, a maturity detection component, and a buffer protection component. A motor is fixedly connected to the left side of the conveyor frame, and a baffle is fixedly connected to the right side of the motor's output end through the conveyor frame. A discharge mechanism is provided at the rear bottom of the conveyor frame. The maturity detection component includes a double-headed cylinder, the top of which is fixedly connected to the conveyor frame. Push plates are fixedly connected to both sides of the output end of the double-headed cylinder. Pressure sensors are fixedly connected to opposite sides of the two push plates, and flexible clamps are fixedly connected to opposite sides of the two pressure sensors. The opposite sides of the two flexible clamps extend into the inner cavity of the conveyor frame. A weighing sensor is fixedly connected to the bottom of the inner cavity of the conveyor frame, and a near-infrared spectrometer is fixedly connected to the top of the conveyor frame. The buffer protection component includes a rubber sheet, and an energy-absorbing soft block is fixedly connected to the rear side of the rubber sheet. An elastic sheet is fixedly connected to the rear side of the energy-absorbing soft block through the baffle, and a fixed frame is fixedly connected to the rear side of the baffle.

[0008] The present invention is further configured such that the discharge mechanism includes an electric cylinder, the top of the electric cylinder is fixedly connected to the conveying frame, a positioning block is fixedly connected to the front side of the output end of the electric cylinder, a discharge opening is opened on the rear side of the bottom of the conveying frame, and a top plate is movably connected between the two sides of the inner cavity of the discharge opening. The electric cylinder can control the position of the positioning block, and the positioning block can squeeze the bottom of the top plate, so that the top plate can control the opening and closing of the discharge opening, and can divert the kiwifruit conveyed inside the conveying frame.

[0009] The present invention is further configured such that slide rails are fixedly connected to the rear sides of both sides of the bottom of the conveying frame, and sliders are slidably connected to the inner cavity of the slide rails. The bottom of the sliders is fixedly connected to the positioning block. The slide rails and sliders can limit the positioning block, enabling it to move back and forth smoothly and increasing its stability during movement.

[0010] The present invention is further configured such that movable openings for use with flexible clamping blocks are provided on both sides of the conveying frame, and sliding rods are fixedly connected to the opposite sides of the two push plates. Sliding sleeves are slidably connected to the surface of the sliding rods, and the top of the sliding sleeves is fixedly connected to the conveying frame. The movable openings facilitate the use of the flexible clamping blocks, enabling them to test the softness and hardness of kiwifruit. The sliding rods and sliding sleeves can limit the push plates, allowing them to move smoothly left and right.

[0011] The present invention is further configured such that the left side of the baffle is movably connected to the inner wall of the conveying frame via a bearing, and a buffer opening is provided on the front side of the baffle to cooperate with the energy-absorbing soft block. The bearing is used to improve the stability of the baffle when it rotates, and the buffer opening can cause the energy-absorbing soft block to move, so as to transmit the impact force generated by the fruit collision.

[0012] The present invention is further configured such that a limiting strip is fixedly connected to the bottom of the rear side of the energy-absorbing soft block, and a positioning plate is fixedly connected to the rear side of the limiting strip through the fixing frame. The limiting strip and the positioning plate can limit the energy-absorbing soft block and prevent it from shifting during the displacement process.

[0013] The present invention is further configured such that both sides of the near-infrared spectrometer are fixedly connected to the transport frame by a mounting frame. The mounting frame is L-shaped, which can stably install and fix the near-infrared spectrometer. The L-shaped mounting frame facilitates the compression and energy absorption of the elastic sheet.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model utilizes a maturity detection component, employing a double-headed cylinder to drive a pusher plate, which in turn moves a flexible clamping block to flexibly hold the kiwifruit within the conveying frame. A pressure sensor detects the deformation of the fruit under pressure in real time and provides feedback on its hardness and softness. A weighing sensor simultaneously collects weight parameters, and a near-infrared spectrometer performs non-destructive testing on the sugar content inside the fruit. After fusing and analyzing multiple detection data, the maturity level is accurately determined. The discharge mechanism controls the top plate to open the discharge opening based on the detection results, thus achieving fruit sorting. This effectively solves the problem of mixed hardness and softness caused by traditional sorting equipment relying on a single parameter, ensuring that the maturity and ready-to-eat window of the same batch of fruit are highly consistent after sorting, reducing the risk of quality fluctuations in the distribution process, and improving the consumer's eating experience.

[0016] 2. This utility model uses a buffer protection component. Before the kiwifruit being transported in the conveying frame comes into contact with the baffle, the rubber sheet absorbs the collision energy of the fruit through its own elastic deformation. Under the impact force, the energy-absorbing soft block moves backward, while at the same time driving the elastic sheet to deform and absorb energy within the fixed frame. The impact force is dispersed step by step through the flexible material, which effectively reduces the risk of skin damage caused by direct collision between the fruit and the baffle, reduces internal tissue damage to the fruit caused by mechanical impact during sorting, and maintains the appearance integrity and edible quality of ready-to-eat kiwifruit.

[0025] Example 1

[0026] Please see Figure 1-5 This utility model relates to an automatic sorting device for ready-to-eat kiwifruit, comprising a conveyor frame 1, a maturity detection component 5, and a buffer protection component 6. A motor 2 is fixedly connected to the left side of the conveyor frame 1. A baffle 3 is fixedly connected to the right side of the motor 2's output end through the conveyor frame 1.

Pressure plates are fixedly connected to opposite sides of the two push plates 52. Force sensor 53, two pressure sensors 53 are fixedly connected to flexible clamping blocks 54 on opposite sides, two flexible clamping blocks 54 on opposite sides penetrate into the inner cavity of conveying frame 1, weighing sensor 55 is fixedly connected to the bottom of the inner cavity of conveying frame 1, near-infrared spectrometer 56 is fixedly connected to the top of conveying frame 1, buffer protection component 6 includes rubber soft sheet 61, energy absorbing soft block 62 is fixedly connected to the rear side of rubber soft sheet 61, energy absorbing soft block 62 penetrates the baffle 3 and is fixedly connected to elastic sheet 63 on the rear side, and fixed frame 64 is fixedly connected to the rear side of baffle 3.

[0027] Specifically: Motor 2 can control the opening and closing of baffle 3, and can perform positioning detection on the kiwifruit when the conveyor frame 1 is conveying it; the discharge mechanism 4 can cooperate with the conveyor frame 1 to divert the fruit, separating soft and hard fruits; the double-headed cylinder 51 can control the position of the two push plates 52; the pressure sensor 53 can cooperate with the flexible clamp 54 to detect the softness and hardness of the fruit; the weighing sensor 55 can detect the weight of the fruit; the near-infrared spectrometer 56 can detect the internal sugar content of the fruit.

[0028] Example 2

[0029] Please see Figure 1-5 Based on Embodiment 1, the discharge mechanism 4 includes an electric cylinder 41. The top of the electric cylinder 41 is fixedly connected to the conveying frame 1. A positioning block 42 is fixedly connected to the front side of the output end of the electric cylinder 41. A discharge opening 43 is provided on the rear side of the bottom of the conveying frame 1. A top plate 44 is movably connected between the two sides of the inner cavity of the discharge opening 43. Slide rails are fixedly connected to the rear sides of both sides of the bottom of the conveying frame 1. A slider is slidably connected to the inner cavity of the slide rail. The bottom of the slider is fixedly connected to the positioning block 42. Movable openings that cooperate with flexible clamping blocks 54 are provided on both sides of the conveying frame 1. Each of the two push plates 52 has a sliding rod fixedly connected to one side of its opposite side. The surface of the sliding rod is slidably connected to a sliding sleeve. The top of the sliding sleeve is fixedly connected to the conveying frame 1. The left side of the baffle 3 is movably connected to the inner wall of the conveying frame 1 through a bearing. The front side of the baffle 3 has a buffer opening for use with the energy-absorbing soft block 62. The bottom of the rear side of the energy-absorbing soft block 62 is fixedly connected to a limit strip. The rear side of the limit strip passes through the fixed frame 64 and is fixedly connected to a positioning plate. Both sides of the near-infrared spectrometer 56 are fixedly connected to the conveying frame 1 through a mounting bracket. The fixed frame 64 is L-shaped.

[0030] Specifically: the electric cylinder 41 can control the position of the positioning block 42, which can press the bottom of the top plate 44, allowing the top plate 44 to control the opening and closing of the discharge opening 43, thus diverting the kiwifruit conveyed inside the conveying frame 1. The slide rail and slider can limit the positioning block 42, enabling it to move smoothly back and forth and increasing its stability during movement. The movable opening facilitates the use of the flexible clamping block 54, allowing it to test the softness and hardness of the kiwifruit. The sliding rod and sliding sleeve can limit the push plate 52, enabling it to move smoothly left and right. The bearing is used to improve the stability of the baffle 3 during rotation. The buffer opening allows the energy-absorbing soft block 62 to be displaced, used to transmit the impact force generated by the fruit collision. The limiting strip and positioning plate can limit the energy-absorbing soft block 62 to prevent it from shifting during displacement. The mounting frame can stably install and fix the near-infrared spectrometer 56. The L-shaped fixing frame 64 facilitates the compression and energy absorption of the elastic sheet 63.

[0031] The working principle of this utility model is as follows: After the kiwi fruit enters the conveyor frame 1, the motor 2 drives the baffle 3 to rotate to a closed state to position the fruit. The double-headed cylinder 51 drives the push plate 52 to move inward, causing the flexible clamping block 54 to contact the fruit surface to form a flexible clamp. The pressure sensor 53 collects the pressure change data in real time during the clamping process. Subsequently, the weighing sensor 55 obtains the fruit weight information. The near-infrared spectrometer 56 located on the top of the fruit emits near-infrared light to the fruit surface and receives the reflected spectrum to analyze the internal sugar content parameters. After processing by the system, multiple detection data are used to generate a maturity judgment result. The electric cylinder 41 of the discharge mechanism 4 controls the conveying position of the fruit according to the judgment signal. When it is necessary to divert the fruit, the electric cylinder 41 drives... The positioning block 42 moves, and the top plate 44 is no longer squeezed by the positioning block 42. The discharge opening 43 is opened, so that fruits of different ripeness are diverted to the corresponding areas. This effectively solves the problem of mixed soft and hardness caused by the reliance on a single parameter in traditional sorting equipment. It ensures that the ripeness of the same batch of fruits after sorting is highly consistent with the ready-to-eat window period, reduces the risk of quality fluctuations in the circulation process, and improves the consumer's eating experience. When the fruit is conveyed to the baffle 3, the rubber soft sheet 61 absorbs the energy of the initial collision through elastic deformation. The energy-absorbing soft block 62 is compressed into the baffle 3 after being impacted, which drives the elastic sheet 63 to deform in the fixed frame 64. This reduces the damage to the internal tissue of the fruit caused by mechanical impact during the sorting process and maintains the appearance integrity and eating quality of ready-to-eat kiwifruit.
