Description

Technical Field

[0001] The invention relates to the technical field of asparagus packaging, and in particular to an intelligent and automated asparagus grading and packaging integrated system. Background Art

[0002] Asparagus is a nutritious vegetable that is rich in vitamins, minerals and dietary fiber. After the asparagus is harvested, it needs to be sorted and graded according to its length and thickness, and the defective ones need to be removed. Then it needs to be washed to remove impurities. Then it needs to be pre-cooled and packaged for sale at the point of sale. The patent with authorization announcement number CN219295766U discloses an automatic packaging equipment for processing asparagus. The application transports asparagus toward the lower hopper through conveyor belt 2, so that the asparagus is adjusted by the sorting component and passes through the lower hopper and falls into the inside of the receiving hopper. At the same time, the packaging box is moved from the top of conveyor belt 1 to one end of base 1 by starting the transfer component, and the lowering component is started to drive the receiving hopper to pour asparagus into the interior of the packaging box. Then the transfer component is started again to drive the packaging box back to the other end of conveyor belt 1, and transported to the bottom of the film sticking component for film sticking packaging, thereby realizing automatic quantitative feeding and packaging of asparagus, further reducing manual intervention and improving work efficiency.

[0003] In the above patent solution, when the asparagus is poured into the packaging box, the asparagus cannot be neatly arranged, resulting in partial accumulation of the asparagus inside the packaging box. The accumulated asparagus is easily squeezed during the packaging process, resulting in the asparagus skin being damaged after friction with each other, increasing the risk of asparagus deterioration. In addition, during the transportation of the packaged asparagus, the asparagus shakes in the packaging box due to road bumps and other reasons. Some tender stem tissues of the asparagus head that are not firmly attached will fall off and remain in the packaging box, affecting the appearance of the asparagus. Additional cleaning and processing are required before sale, which increases the cost. Therefore, the present invention proposes an intelligent and automated asparagus grading and packaging integrated system. Summary of the invention

[0027] Two groups of limit blocks 63 are slidingly arranged on the surface of the storage box 6, and return springs 631 are fixedly arranged on the surfaces of the two groups of limit blocks 63. The other ends of the return springs 631 are fixed to the inner surface of the storage box 6. The two groups of limit blocks 63 are on the same horizontal plane, and a number of packaging boxes stacked in sequence are clamped between the two groups of limit blocks 63.

[0028] A two-way conveying platform 8 is also provided inside the shell 1, and the two-way conveying platform 8 can convey the packaging boxes containing asparagus in two directions. An intelligent baffle is provided inside the two-way conveying platform 8, which can block and release the packaging boxes containing asparagus at a specified position.

[0029] 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 conveying component 9 in a direction parallel to the slit 92. The conveyor belt 91 drives the asparagus to move when it runs. When the asparagus passes through the slit 92, the asparagus with a size smaller than the distance between the two sets of conveyor belts 91 will fall downward to the inside of the lower hopper 12 and be packaged by the packaging device below the lower hopper 12. Asparagus with a size 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 and is then packaged by the packaging device there, thereby achieving a graded packaging effect.

[0030] When the asparagus falls into the lower hopper 12, the asparagus will fall onto the surface of the conical conveyor belt 25 in the sorting assembly 2 through the opening below the lower hopper 12; at the same time, the first motor 21 is started, and the output end of the first motor 21 drives the bevel gear 221 to rotate clockwise through the driving rod 22; the rotation of the bevel gear 221 simultaneously drives the first transmission shaft 23 and the second transmission shaft 24 to rotate in meshing, the rotation of the first transmission shaft 23 drives the feeding belt 26 to rotate, and the rotation of the second transmission shaft 24 drives the conical conveyor belt 25 to rotate, and the conical conveyor belt 25 transports the asparagus toward the collecting bucket 13 when it rotates. Since the conical conveyor belt 25 is arranged in a high and low position as a whole, when the asparagus falls onto the surface of the conical conveyor belt 25, the relatively straight asparagus will roll on the surface of the conical conveyor belt 25 in the opposite direction of the collecting bucket 13. At the same time, since the surface of the conical conveyor belt 25 is arranged in a conical shape, 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 at the same time; When the relatively bent asparagus falls onto the surface of the conical conveyor belt 25, it will not roll due to the uneven distribution of its center of gravity and the large rotational resistance at both ends, and will be transported by the conical conveyor belt 25 to the inside of the collecting bucket 13 for collection.

[0031] 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 knocking block 271 and the first protrusion 272 to rotate. During the rotation of the knocking block 271, the conical conveyor belt 25 is intermittently and slightly patted to improve the rolling effect of the asparagus; at the same time, the rotation of the first protrusion 272 controls the dredging rod 210 to slide back and forth up and down at the gap 92, which can push the asparagus stuck in the gap 92 so that it can continue to be transported by the conveyor belt 91, thereby improving the sorting accuracy.

[0032] In order to prevent the asparagus from being locally accumulated inside the packaging box, during the rotation of the driving rod 22, the driving disc 41 is driven to rotate by the second transmission belt 42. The driving disc 41 rotates and drives the slide plate 43 to slide back and forth inside the shell 1 through the clamping block 411. When the slide plate 43 slides back and forth, it will drive the two sets of friction rods 431 to move synchronously, so as to achieve the effect of the asparagus falling at different positions above the packaging box. When the friction rod 431 moves, the matching gears 4311 at both ends thereof mesh with the rack inside the shell 1. The rack is fixed inside the shell 1. When the friction rod 431 moves, it rotates through the meshing relationship between the matching gear 4311 and the rack. The friction rod 431 in the rotation process is more conducive to the falling effect of the asparagus, and the asparagus is prevented from piling up on the surface of the shrink plate 44. Furthermore, since one end of the filter plate 45 is rotationally limited inside the housing 1, one end of the retracting plate 44 is rotated on the surface of the slide plate 43, and the retracting plate 44 slides inside the filter plate 45, when the slide plate 43 reciprocates, the retracting plate 44 will intermittently slide and retract inside the filter plate 45. During the sliding and retracting process, the angle between the retracting plate 44 and the filter plate 45 is constantly changing, thereby further improving the falling efficiency of the asparagus. Furthermore, in order to remove some loosely adhered tender stem tissues on the surface of the asparagus 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, wherein the first brush plate 31 is eccentrically connected to the first transmission shaft 23 through a first connecting rod 311, and the first transmission shaft 23 is controlled to slide back and forth left and right inside the housing 1 during rotation, thereby brushing the asparagus to make the loosely adhered tender stem tissues fall, and at the same time, the second brush plate 32 is connected to the clamping block 41 through a second connecting rod 321 and a connecting shaft 322. 1, the center of the connecting shaft 322 and the center of the driving disk 41 are also in an eccentric position, and the second brush plate 32 is controlled to slide back and forth on the surface of the fixing seat 33, so as to squeeze and release the asparagus; since the first brush plate 31 and the second brush plate 32 move simultaneously, the asparagus is subjected to forces of different directions and magnitudes between the first brush plate 31 and the second brush plate 32, so that the tender stem tissue that is not firmly adhered can be effectively and quickly removed; at the same time, the asparagus transported by the feeding belt 26 can be buffered to prevent it from directly contacting with the filter plate 45 and being damaged.

[0033] Furthermore, the removed tender stem tissue will fall onto the surface of the filter plate 45, and the tender stem tissue stuck on the surface of the filter plate 45 can be removed by the cleaning block 441 sliding back and forth on the surface.

[0034] A weight sensor is provided on the inner surface of the carrier plate 47, and the packaging box is located above the weight sensor. When the asparagus in the packaging box is filled to a 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 two-way conveyor 8 are started; After the cylinder 48 is started and retracted, the asparagus inside the packaging box is driven to move downward through the supporting plate 47. While moving downward, the supporting plate 47 will squeeze the rocker arm 491 downward, causing the rocker arm 491 to swing. During the swinging process of the rocker arm 491, the packaging box on the surface of the supporting plate 47 is pushed out by the pushing plate 493. When the pushed-out part of the packaging box contacts the two-way conveying platform 8, the packaging box will be conveyed by several rollers on the surface of the two-way conveying platform 8 until it stops running after corresponding to the position of the cap; and the cylinder 48 is controlled to reset upward.

[0035] Then, the second motor 51 is started, and the screw rod 511 rotates to control the slide 52 to drive the conical extrusion bar 521 and the cover push plate 522 to move. When the cover push plate 522 moves, it can always push the cover at the highest position toward the packaging box on the surface of the two-way conveying platform 8 until the cover completely falls on the upper surface of the packaging box; and the conical extrusion bar 521 is gradually inserted into the overlapping part between the two groups of packaging boxes at the bottom, and through extrusion, the packaging box at the bottom passes the limit block 63 and falls on the surface of the conveying belt 53; At the same time, the screw rod 511 rotates to drive the conveyor belt 53 to rotate, and the packaging box dropped on the surface is conveyed to the surface of the carrier plate 47 to prepare for the next group of packaging; after this effect is completed, the second motor 51 is controlled to reverse and reset; the two-way conveyor platform 8 is started again, until the two-way conveyor platform 8 conveys the packaging box with asparagus to the bottom of the pressing plate 712 and then stops running; When the first motor 21 is started again, when the conical conveyor belt 25 rotates, the second protrusion 252 is driven to rotate through the first driven shaft 251, thereby intermittently squeezing the moving frame 71.
