Description

Technical Field

[0001] This invention relates to the field of asparagus packaging technology, specifically to an intelligent automated integrated system for grading and packaging asparagus. Background Technology

[0002] Asparagus is a nutritious vegetable, rich in various vitamins, minerals and dietary fiber. After harvesting, asparagus needs to be sorted and graded according to its length and thickness to remove defective products. Then it is washed to remove impurities. After that, it is pre-cooled and preserved, and then packaged and sold at sales points.

[0003] Patent CN219295766U discloses an automatic packaging device for asparagus processing. This application uses a second conveyor belt to transport asparagus towards the lower hopper, so that the asparagus is adjusted by a sorting component and falls evenly through the lower hopper into the receiving hopper. At the same time, the transfer component is activated to move the packaging box from the top of the first conveyor belt to one end of the base, and the lowering component is activated to drive the receiving hopper to pour asparagus into the packaging box. Then, the transfer component is activated again to drive the packaging box back to the other end of the first conveyor belt and transport it to the bottom of the film-applying component for film packaging. This achieves automatic quantitative feeding and packaging of asparagus, further reducing manual intervention and improving work efficiency.

[0004] In the aforementioned patented solutions, the asparagus cannot be neatly arranged when being poured into the packaging box, resulting in localized accumulation. This accumulation can easily cause compression during packaging, leading to friction and damage between the asparagus skins, increasing the risk of spoilage. Furthermore, during transportation, the packaged asparagus may shake inside the box due to road bumps, causing some loosely attached tender stem tissues to detach and remain inside the packaging box, affecting its appearance. This requires additional cleaning and processing before sale, increasing costs. Therefore, this invention proposes an intelligent, automated, integrated asparagus grading and packaging system.

[0040] like Figure 2 and Figure 3 As shown, a sorting component 2 is located inside the shell 1 below the feeding hopper 12, used to sort the asparagus that has been graded and is curved or relatively straight.

A collecting hopper 13 is located inside the shell 1 near the air supply component 7, used to collect asparagus that is curved in appearance.

[0041] Specifically, such as Figure 4 As shown, the cleaning assembly 3 includes a first brush plate 31, a second brush plate 32, and a fixing base 33.

A limiting groove 331 is formed on the surface of the fixing base 33. The second brush plate 32 slides on the surface of the limiting groove 331.

[0042] Specifically, such as Figures 5 to 7As shown, the sorting component 2 includes a first motor 21. The output end of the first motor 21 is fixedly connected to a drive rod 22. The end of the drive rod 22 away from the first motor 21 is fixedly connected to a bevel gear 221. The surface of the bevel gear 221 is meshed with a first transmission shaft 23 and a second transmission shaft 24. The first transmission shaft 23 passes through the interior of the second transmission shaft 24 and is connected to it by a bearing. A feeding belt 26 is sleeved on the surface of the first transmission shaft 23, and a tapered conveyor belt 25 is sleeved on the surface of the second transmission shaft 24. The tapered conveyor belt 25 has a tapered surface, with the end near the bevel gear 221 being thicker than the other end. It is also arranged at different heights inside the housing 1, with the side near the cleaning component 3 being lower than the other side. The end of the first connecting rod 311 away from the first brush plate 31 is eccentrically rotated and sleeved on the end face of the first transmission shaft 23.

[0043] Furthermore, the feeding belt 26 is also sleeved on one end of the second driven shaft 27. Several sets of striking blocks 271 are fixedly connected to the surface of the second driven shaft 27. A first protrusion 272 is fixedly connected to the end of the surface of the second driven shaft 27 away from the feeding belt 26.

[0044] Specifically, such as Figure 8 and Figure 9 As shown, the loading assembly 4 includes a drive disc 41 and a second transmission belt 42. A locking block 411 is eccentrically connected to the upper surface of the drive disc 41. One end of the connecting shaft 322, away from the second connecting rod 321, is fixed to the upper end of the locking block 411. A sliding plate 43 is slidably fitted onto the surface of the locking block 411. Two sets of friction rods 431 are rotatably threaded through the end of the sliding plate 43 away from the locking block 411.

The end of the shrink plate 44 away from the friction rod 431 is slidably sleeved inside the filter plate 45. The end of the filter plate 45 away from the shrink plate 44 rotates on the surface of the shell 1.

[0045] like Figure 10 As shown, the filling assembly 4 also includes a cylinder 48 and a limiting plate 49. A bearing plate 47 is fixedly connected to the output end surface of the cylinder 48.

[0046] like Figure 15 As shown, the gas delivery assembly 7 includes a moving frame 71 and a piston chamber 72. A piston plate 711 is fixedly connected to the middle of the moving frame 71. The piston plate 711 slides in a sealed manner inside the piston chamber 72. The piston chamber 72 is fixed to the surface of the housing 1. A pressing plate 712 is fixedly connected to the lower end of the moving frame 71.

[0047] Furthermore, an intake pipe and an exhaust pipe are connected through the surface of the piston chamber 72, and both are equipped with one-way valves with opposite valve directions. The intake pipe is connected to the refrigeration equipment, and the exhaust pipe is connected through the housing 1.

[0048] like Figures 11 to 14 As shown, a storage bin 6 is also provided inside the housing 1. A picking and feeding component 5 is provided on the surface of the storage bin 6. The picking and feeding component 5 includes a second motor 51. A lead screw 511 is fixedly connected to the output end of the second motor 51. A conveyor belt 53 is driven to the end of the lead screw 511 away from the second motor 51. A number of push blocks 531 are fixedly connected to the surface of the conveyor belt 53. A slide block 52 is meshed and driven to the surface of the lead screw 511. A tapered extrusion strip 521 is fixedly connected to the top of the slide block 52. A push cover plate 522 is fixedly connected to the bottom of the slide block 52.

[0049] The surface of the storage box 6 is provided with a through groove 61, the slide 52 slides on the surface of the through groove 61, the bottom of the through groove 61 is provided with an extrusion plate 62, the bottom of the extrusion plate 62 is fixedly connected with an extrusion spring 621, the end of the extrusion spring 621 away from the extrusion plate 62 is fixed to the bottom surface of the storage box 6, and the upper surface of the extrusion plate 62 is provided with a number of sequentially stacked caps.

[0050] Two sets of limiting blocks 63 are slidably arranged on the surface of the storage box 6. A return spring 631 is fixedly arranged on the surface of the two sets of limiting blocks 63. The other end of the return spring 631 is fixed to the inner surface of the storage box 6. The two sets of limiting blocks 63 are on the same horizontal plane. Several packaging boxes are stuck between the two sets of limiting blocks 63.

[0051] The housing 1 is also equipped with a bidirectional conveyor 8, which can transport the packaging box containing asparagus in two directions. The bidirectional conveyor 8 is equipped with an intelligent baffle, which can block and release the packaging box containing asparagus at a designated position.

[0052] The specific implementation process and working principle of this embodiment are as follows: Asparagus is placed on the conveyor belt 91 on the surface of the grading conveyor component 9 in a direction parallel to the gap 92. The movement of the conveyor belt 91 will drive the asparagus to move. When the asparagus passes through the gap 92, asparagus with a size smaller than the distance between the two sets of conveyor belts 91 will fall down into the inside of the feeding hopper 12 and be packaged by the packaging device below the feeding hopper 12.

[0053] Asparagus that is larger than the distance between the two sets of conveyor belts 91 will cross the gap 92 and continue to move with the conveyor belt 91 until it falls into the next larger gap 92, where it will be packaged by the packaging device to achieve a graded packaging effect.

[0054] When asparagus falls into the hopper 12, it falls through the opening at the bottom of the hopper 12 onto the surface of the conical conveyor belt 25 in the sorting assembly 2. At the same time, the first motor 21 is started, and its output end drives the bevel gear 221 to rotate clockwise through the drive rod 22. The rotation of the bevel gear 221 drives the first drive shaft 23 and the second drive shaft 24 to mesh and rotate. The rotation of the first drive shaft 23 drives the feeding belt 26 to rotate, and the rotation of the second drive shaft 24 drives the conical conveyor belt 25 to rotate. When the conical conveyor belt 25 rotates, it transports the asparagus toward the collection hopper 13. Since the conical conveyor belt 25 is set at different heights, when the asparagus falls onto the surface of the conical conveyor belt 25, the relatively straight asparagus will roll in the opposite direction to the collection hopper 13 on the surface of the conical conveyor belt 25. At the same time, since the surface of the conical conveyor belt 25 is conical, when the straight asparagus rolls on its surface, its direction will be deflected and it will roll toward the surface of the feeding belt 26.

[0055] When relatively curved asparagus falls onto the surface of the conical conveyor belt 25, it will not roll due to its uneven center of gravity distribution and the large rotational resistance at both ends. Instead, it will be transported by the conical conveyor belt 25 to the inside of the collection hopper 13 for collection.

[0056] Furthermore, the rotation of the feeding belt 26 drives the second driven shaft 27 to rotate, and the rotation of the second driven shaft 27 drives the striking block 271 and the first protrusion 272 to rotate. During the rotation of the striking block 271, it intermittently and slightly taps the conical conveyor belt 25 to improve the rolling effect of the asparagus. At the same time, the rotation of the first protrusion 272 controls the unblocking rod 210 to slide up and down at the gap 92, which can push the asparagus stuck in the gap 92 so that it can continue to be conveyed by the conveyor belt 91, improving the sorting accuracy.

[0057] To prevent asparagus from piling up inside the packaging box, the second transmission belt 42 drives the drive disc 41 to rotate during the rotation of the drive rod 22. The rotation of the drive disc 41 drives the slide plate 43 to slide back and forth inside the shell 1 through the snap-fit ​​block 411. When the slide plate 43 slides back and forth, it drives the two sets of friction rods 431 to move synchronously, thus achieving the effect of asparagus falling at different positions above the packaging box. While the friction rods 431 are moving, the gears 4311 at both ends of them mesh with the rack inside the shell 1. The rack is fixed inside the shell 1. When the friction rods 431 move, they rotate through the meshing relationship between the gears 4311 and the rack. The friction rods 431 during the rotation process are more conducive to the falling effect of the asparagus and prevent the asparagus from piling up on the surface of the shrink plate 44.

[0058] Furthermore, since one end of the filter plate 45 is limited to rotation inside the housing 1, and one end of the shrink plate 44 rotates on the surface of the slide plate 43, and the shrink plate 44 slides inside the filter plate 45, when the slide plate 43 reciprocates, the shrink plate 44 will intermittently slide and shrink inside the filter plate 45. During the sliding and shrinking process, the angle between the shrink plate 44 and the filter plate 45 changes continuously, further improving the falling efficiency of the asparagus.

[0059] Furthermore, to remove some loosely adhering tender stem tissue from the asparagus surface before packaging, a first brush plate 31 and a second brush plate 32 are provided between the feeding belt 26 and the filter plate 45. The first brush plate 31 is eccentrically connected to the first drive shaft 23 via a first connecting rod 311. During the rotation of the first drive shaft 23, the first brush plate 31 is controlled to slide back and forth inside the housing 1, thereby brushing the asparagus to make the loosely adhering tender stem tissue fall off. At the same time, the second brush plate 32 is connected to the locking block 41 via a second connecting rod 321 and a connecting shaft 322. 1. The center of the connecting shaft 322 and the center of the drive disc 41 are both in an eccentric position, which controls the second brush plate 32 to slide back and forth on the surface of the fixed seat 33, thereby squeezing and releasing the asparagus. Since the movement of the first brush plate 31 and the second brush plate 32 is carried out simultaneously, the asparagus is subjected to forces of different directions and magnitudes between the first brush plate 31 and the second brush plate 32, which can effectively and quickly remove the loosely attached tender stem tissue. At the same time, it can also buffer the asparagus conveyed and falling by the feeding belt 26 to prevent it from directly contacting the filter plate 45 and being damaged.

[0060] Furthermore, the removed tender stem tissue will fall onto the surface of the filter plate 45, and the tender stem tissue stuck to the surface of the filter plate 45 can be removed by sliding the cleaning block 441 back and forth on its surface.

[0061] A weight sensor is provided on the inner surface of the support plate 47. The packaging box is located above the weight sensor. When the asparagus inside the packaging box is filled to the set weight range, the weight sensor sends a command to the control panel 11, and the control panel 11 immediately stops the operation of the first motor 21; at the same time, the cylinder 48 and the bidirectional conveyor 8 are started.

[0062] After the cylinder 48 is started and retracts, it drives the asparagus inside the packaging box to move downward through the support plate 47. As the support plate 47 moves downward, it will press down on the swing rod 491, causing the swing rod 491 to swing. During the swinging process, the swing rod 491 pushes the packaging box on the surface of the support plate 47 through the pusher plate 493. When the pushed part of the packaging box contacts the bidirectional conveyor table 8, the packaging box will be conveyed by several rollers on the surface of the bidirectional conveyor table 8 until it corresponds to the sealing position and then stops running; and control the cylinder 48 to reset upward.

[0063] Next, the second motor 51 is started, and the lead screw 511 rotates to control the slide 52 to move the conical extrusion bar 521 and the push cover plate 522. When the push cover plate 522 moves, it can always push the highest cover towards the packaging box on the surface of the bidirectional conveyor table 8 until the cover falls completely onto the upper surface of the packaging box. Meanwhile, the conical extrusion bar 521 gradually inserts into the overlapping area between the two sets of packaging boxes that are always at the bottom, and through extrusion, the lowest packaging box passes over the limit block 63 and falls onto the surface of the conveyor belt 53.

[0064] At the same time, the rotation of the lead screw 511 will drive the conveyor belt 53 to rotate, and transport the packaging boxes that have fallen onto its surface to the surface of the carrier plate 47 to prepare for the packaging of the next group; after this effect is completed, the second motor 51 is controlled to reverse and reset; the bidirectional conveyor 8 is started again until the bidirectional conveyor 8 transports the packaging box with asparagus to the bottom of the pressing plate 712 and then stops running.

[0065] When the first motor 21 is restarted, the second protrusion 252 is rotated through the first driven shaft 251 when the tapered conveyor belt 25 rotates, thereby intermittently squeezing the moving frame 71. A spring is provided between the piston plate 711 and the piston chamber 72, which causes the piston plate 711 to slide up and down inside the piston chamber 72, so that the cold air generated by the refrigeration equipment can be delivered to the inside of the housing 1 to achieve a cooling effect.

[0066] Furthermore, as the piston plate 711 moves up and down, the pressing plate 712 presses the packaging box containing asparagus and the cap on the surface of the bidirectional conveyor table 8, so that the cap can be locked onto the upper surface of the packaging box to achieve the sealing packaging operation.

[0067] The embodiments described above merely illustrate implementation methods of the present invention and should not be construed as limiting the scope of the invention patent, nor as imposing any form of limitation on the structure of the present invention. It should be noted that those skilled in the art can make various changes and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
