Description

Technical Field

[0001] This utility model relates to the field of corn vacuum packaging technology, and in particular to a vacuum packaging device for fresh corn. Background Technology

[0002] Currently, in the feeding stage of vacuum packaging equipment for fresh corn, the common method is to place a collection box directly below the discharge port to receive the packaged fresh corn. However, this method lacks effective guidance and restraint when the corn falls from the discharge port, resulting in the corn piling up in a rather disorderly manner in the collection box, making it difficult to arrange neatly. This not only affects subsequent counting and handling operations but also hinders the efficient use of space. Furthermore, during the falling process, the corn may fall to the ground, thereby affecting product quality, reducing production efficiency, and increasing production costs. Utility Model Content

[0003] In view of the problems existing in the above and / or existing vacuum packaging equipment for fresh corn, this utility model is proposed.

[0004] Therefore, the problem that this utility model aims to solve is the defect of disordered placement caused by the corn falling haphazardly during the feeding of fresh corn vacuum packaging equipment.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a vacuum packaging device for fresh corn. The vacuum packaging device for fresh corn includes a main component 100, including a frame 101, a conveyor belt 102 on the frame 101, a heating plate 103 fixed on the conveyor belt 102, and a vacuum heating component 104 on the frame 101. The fresh corn to be packaged is placed on the conveyor belt 102, with part of the packaging bag positioned above the heating plate 103. After the conveyor belt 102 moves the corn to be packaged to the packaging station, the vacuum heating component 104 performs the vacuum packaging operation. The packaged corn is then transported again via the conveyor belt 102. This is prior art, and this solution will not be described in detail here. Those skilled in the art can clearly understand the working principle.

[0032] The unloading assembly 200 is disposed on the conveyor belt 102 and includes an unloading component 201. A collecting component 202 is disposed on one side of the unloading component 201. The unloading component 201 is used to receive packaged corn conveyed from the conveyor belt 102, and the collecting component 202 is used to place the corn received by the unloading component 201 in an orderly manner at a designated position.

[0033] The unloading component 201 includes a support frame 2011 disposed on one side of the conveyor belt 102. The height of the support frame 2011 is slightly lower than that of the conveyor belt 102, so that the processed corn can be moved into the support frame 2011 under the action of the conveyor belt 102. Since the height difference between the two is small, the position of the corn will not change much during the movement.

[0034] An extension block 2012 is fixed on the support frame 2011, and a rotating shaft 2013 is fixed on the extension block 2012. A rotating plate 2014 is fitted over the rotating shaft 2013. There are two sets of extension blocks 2012, rotating shaft 2013, and rotating plates 2014. The initial positions of the two rotating plates 2014 are parallel to the ground. The two rotating plates 2014 together form the bottom surface of the support frame 2011. The support frame 2011 itself has a bottom surface, so that the processed corn falls onto the two rotating plates 2014 under the action of the conveyor belt 102. The corn will only fall downward when the two rotating plates 2014 rotate simultaneously and open the bottom surface of the support frame 2011.

[0035] An extension plate 2015 is fixed on the support frame 2011. A cylinder 2016 is installed at the bottom of the extension plate 2015. The extension plate 2015 and the telescopic column of the cylinder 2016 are movably connected. The cylinder 2016 is used to drive the support frame 2011 to move up and down. There are two cylinders 2016 and extension plates 2015, located on both sides of the support frame 2011. A baffle 2017 is installed on one side of the cylinder 2016. A force plate 2018 is fixed on one side of the rotating plate 2014. Through the cooperation of the baffle 2017 and the force plate 2018, the rotating plate 2014 can rotate when the support frame 2011 moves vertically, thereby opening the bottom surface of the support frame 2011 and allowing the corn to fall.

[0036] In the initial state, the support frame 2011 is at its highest position, which can stably support the packaged corn. At this time, the force plate 2018 is not in contact with the baffle 2017. Then, the cylinder 2016 is activated, which drives the extension plate 2015 to move, thereby moving the support frame 2011 downward and closer to the collection component 202 below. The force plate 2018 will also move downward. When the force plate 2018 contacts the baffle 2017, the baffle 2017 will apply pressure to the force plate 2018, thereby causing the force plate 2018 to drive the rotating plate 2014 to rotate, thereby opening the bottom of the support frame 2011, allowing the corn to fall vertically to the collection component 202.

[0037] Example 2

[0038] Reference Figures 2-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the collecting component 202 includes a base 2021 located at the bottom of the support frame 2011. The cylinder 2016 and the baffle 2017 are both connected to the base 2021 by bolts. The base 2021 provides stable support for the entire unloading assembly 200.

[0040] Specifically, a sliding plate 2022 is slidably connected to the base 2021. The sliding plate 2022 can slide on the base 2021 and is used to drive the collection box 2029 to move. A connecting rod 2023 is fixed to the sliding plate 2022, and a reciprocating roller 2024 is sleeved outside the connecting rod 2023. A rotating column 2025 is fixed to one end of the reciprocating roller 2024.

[0041] A gear 2026 is sleeved outside the rotating column 2025, and a rack 2027 is arranged on one side of the extension plate 2015. Through the cooperation of the rack 2027 and the gear 2026, when the carrying frame 2011 rises, it will drive the rack 2027 to move, thereby causing the gear 2026 to rotate, further causing the rotating column 2025 to rotate, and then causing the reciprocating roller 2024 to rotate. In combination with the connecting rod 2023, finally, the sliding plate 2022 performs a reciprocating motion, thereby changing the position of the collection box 2029 so that the corn can be arranged in multiple rows.

[0042] Specifically, a slider 2028 is fixed to the connecting rod 2023. The slider 2028 slides in the spiral groove on the reciprocating roller 2024. The reciprocating roller 2024 is a prior art and will not be elaborated in this solution. When the reciprocating roller 2024 rotates, the slider 2028 slides in the spiral groove, thereby causing the connecting rod 2023 to perform a reciprocating motion along the direction of the reciprocating roller 2024, and further driving the sliding plate 2022 to move.

[0043] A collection box 2029 is placed on the sliding plate 2022. A partition 2029-1 is arranged in the collection box 2029. The partition 2029-1 divides the collection box 2029 into two chambers. Corn can be placed in the two chambers to form a multi-row arrangement. A fixed frame 2022-1 is arranged on the sliding plate 2022. The fixed frame 2022-1 is similar to the shape of "ji". The fixed frame 2022-1 is used to determine the placement position of the collection box 2029 on the sliding plate 2022. When placing the collection box 2029, it is necessary to pay attention to making the outer wall of the collection box 2029 fit with the inner wall of the fixed frame 2022-1.

[0044] In the initial state, the connecting rod 2023 is located at the limit position at one end of the reciprocating roller 2024. At this time, the carrying frame 2011 and one of the chambers in the collection box 2029 are in the coaxial position, and the corn will fall into this chamber.

[0045] When the cylinder 2016 is started once, the carrying frame 2011 moves up and down for one cycle. During the cycle when the carrying frame 2011 returns upward, the number of turns of the gear 2026 is just enough to make the connecting rod 2023 move half a cycle on the reciprocating roller 2024. The connecting rod 2023 will move to the limit position at the other end of the reciprocating roller 2024 next time. At this time, the carrying frame 2011 and the other chamber are in the coaxial position, and the corn will fall into this chamber. The two chambers are alternately collected, and the height of the collection box 2029 meets the placement of multiple layers of corn.

[0046] Specifically, the unloading assembly 200 also includes an auxiliary component 203 located on the rotating column 2025. The auxiliary component 203 is used to restrict the gear 2026 to drive the rotating column 2025 to rotate only when the carrier frame 2011 is moving upward, thereby changing the position of the collection frame 2029.

[0047] A rotating groove 2025-1 is provided on the rotating column 2025. A fixed column 2031 is fixed to the inner wall of the rotating groove 2025-1. A pawl 2032 is sleeved on the fixed column 2031. A slot 2026-1 is provided on the gear 2026. There are multiple slots 2026-1. Each slot 2026-1 has an inclined surface and multiple right-angled surfaces. The pawl 2032 can engage with one of the right-angled surfaces of the slot 2026-1. The pawl 2032 and the slot 2026-1 together form a "ratchet and pawl" structure. When the bearing frame 2011 moves downward, the rack 2027 moves downward and engages with the gear 2026, causing the gear 2026 to rotate counterclockwise. At this time, the inclined surface of the gear 2026 presses against the pawl 2032, causing the pawl 2032 to rotate around the fixed column 2031, without causing the rotating column 2025 to rotate, and thus the reciprocating roller 2024 will not rotate.

[0048] When the carrier frame 2011 moves upward, the rack 2027 moves upward, causing the gear 2026 to rotate clockwise. The right-angled surface of the pawl 2032 fits into the right-angled surface of the slot 2026-1, which will hinder the rotation of the gear 2026. This allows the rotating column 2025 to rotate with the rotation of the gear 2026, thereby driving the reciprocating roller 2024 to rotate and changing the position of the collection frame 2029.

[0049] Specifically, a support plate 20210 is connected to one end of the rack 2027 by a bearing. The support plate 20210 is fixed on the base 2021. There are multiple support plates 20210. One end of the reciprocating roller 2024 is also connected to a support plate 20210 by a bearing. One side of the rotating column 2025 is also connected to a support plate 20210 by a bearing. The multiple support plates 20210 together provide stable support for the reciprocating roller 2024 and the rotating column 2025.

[0050] Example 3

[0051] Reference Figures 1-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0052] Specifically, a first torsion spring 2019 is fixed to one side of the force plate 2018, and the other end of the first torsion spring 2019 is fixed to the extension block 2012. The first torsion spring 2019 is used to maintain the initial state of the rotating shaft 2013. The elastic force of the first torsion spring 2019 is very large. Even if a lot of corn is piled on the rotating shaft 2013, the rotating shaft 2013 will still be in a horizontal state. Only when the bearing frame 2011 moves downward and the baffle 2017 squeezes the force plate 2018 will the rotating shaft 2013 rotate and the first torsion spring 2019 be squeezed. When the baffle 2017 separates from the force plate 2018, the first torsion spring 2019 drives the rotating shaft 2013 back to the initial position and becomes horizontal again.

[0053] Specifically, a second torsion spring 2033 is sleeved on the fixed post 2031. The two ends of the second torsion spring 2033 are fixed to the inner wall of the rotating groove 2025-1 and the pawl 2032, respectively. The second torsion spring 2033 is used to cooperate with the pawl 2032, provide the restoring force of the pawl 2032, and ensure that the pawl 2032 can always engage with the slot 2026-1 to complete the restriction of unidirectional rotation.

[0054] Specifically, there are two wheels 20211 fixed on the sliding plate 2022, located on both sides of the same end of the sliding plate 2022, so that the sliding plate 2022 can maintain its stability when sliding relative to the base 2021.

[0055] There are two connecting rods 2023. One of the connecting rods 2023 has a slide rod 20212 inserted inside. The slide rod 20212 has two support plates 20210 connected to the bearings on both sides. The slide rod 20212 and the reciprocating roller 2024 together restrict the movement of the sliding plate 2022 to ensure the stability of the movement of the sliding plate 2022.

[0056] Specifically, a wedge block 20213 is fixed on one side of the base 2021. The wedge block 20213 facilitates the handling of the collection frame 2029 filled with corn. When the collection frame 2029 is full of corn, the handle on the side of the collection frame 2029 is pulled to pull the collection frame 2029 down along the wedge block 20213 to complete the unloading.

[0057] In use, the processed corn is transferred to two rotating plates 2014 by the conveyor belt 102. Then, the cylinder 2016 is activated, which drives the extension plate 2015 to move, thereby moving the carrying frame 2011 downward and closer to the collection frame 2029 below. The force plate 2018 will also move downward. When the force plate 2018 contacts the baffle 2017, the baffle 2017 will apply pressure to the force plate 2018, thereby causing the force plate 2018 to drive the rotating plate 2014 to rotate, thereby opening the bottom of the carrying frame 2011, allowing the corn to fall vertically into one of the chambers in the collection frame 2029.

[0058] Then the carrying frame 2011 moves upward, the baffle 2017 moves away from the force plate 2018, and the first torsion spring 2019 drives the rotating shaft 2013 back to the initial position, making it horizontal again, so as to receive the packaged corn next time.

[0059] When the carrying frame 2011 moves upward, the rack 2027 moves upward, causing the gear 2026 to rotate clockwise. The right-angled surface of the pawl 2032 engages with the right-angled surface of the slot 2026-1, hindering the rotation of the gear 2026. This allows the rotating column 2025 to rotate with the gear 2026, thereby driving the reciprocating roller 2024 to rotate. The slider 2028 slides in the spiral groove, causing the connecting rod 2023 to reciprocate along the direction of the reciprocating roller 2024. This, in turn, drives the sliding plate 2022 to move, changing the position of the collecting frame 2029. At this time, the carrying frame 2011 and another chamber are coaxial. The next batch of corn will fall into this chamber. The two chambers collect corn alternately. The height of the collecting frame 2029 is sufficient for placing multiple layers of corn. When the collecting frame 2029 is full of corn, the handle on the side of the collecting frame 2029 is pulled to pull the collecting frame 2029 down along the inclined block 20213, thus completing the unloading.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
