Description

Technical Field

[0001] This invention relates to the field of cold chain technology, specifically to a cold chain surface inactivation system. Background Technology

[0002] Viruses can appear in our lives anytime, anywhere. Some viruses are highly contagious and can spread rapidly between animals and people, posing a serious threat to the lives of both. To ensure the safety of everyday products, packaging bags in cold chain environments typically undergo sterilization, disinfection, and inactivation treatment.

[0003] In existing technologies, the cold chain packaging bags are placed inside the inactivation box, and the bacteria and viruses on the surface of the packaging bags are inactivated by plasma inactivation or chemical inactivation.

[0004] However, the packaging bags still need to be transported and transferred between the surface inactivation process and the cold chain location, which means that the surface of the packaging bags is still at risk of being attached to viruses. In addition, during the inactivation process, the packaging bags are far away from the inactivation device and their bottoms are in close contact with the conveyor mechanism, which often requires repeated inactivation of the packaging bag surface, greatly increasing the risk of bacterial and viral reattachment.

[0024] Please refer to Figures 1 to 10. This invention provides a technical solution: a cold chain surface inactivation system, including a conveyor 1, with a first support 2 and a second support 21 respectively installed above the front and rear sides of the conveyor 1, and an inactivation chamber 3 installed above the middle of the conveyor 1; the inactivation chamber 3 is a two-piece assembled chamber structure, spliced ​​onto the outer side of the middle of the conveyor 1, with an inactivation device 6 installed on the inner rear wall of the inactivation chamber 3; a purification device 4, installed above both sides of the inactivation chamber 3; a first lifting plate 5 and a second lifting plate 51, installed above the middle of the inactivation chamber 3, used in conjunction with the inactivation device 6; a storage box 7, containing packaging bags to be cold-chained, which slides horizontally on the conveyor 1, with an opening and closing cover 71 on top of the storage box 7; and a gear 8. Gear 8 is located on the lower rear side of storage box 7 and is movably connected to storage box 7. A first helical gear 82 is provided on the front side of gear 8. Lifting component 9 meshes with the first helical gear 82 and is movably connected to the upper cover 71. Example 2

[0025] The cold chain surface inactivation system disclosed in Embodiment 2 of the present invention has a structure that is basically the same as that in Embodiment 1. The difference is that the inactivation chamber 3 has openings on the left and right sides, and curtains 31 are provided at the openings on both sides of the inactivation chamber 3. Pipes 32 are respectively provided on the upper sides of the inactivation chamber 3. The inner side of the pipes 32 penetrates the inner walls of the upper sides of the inactivation chamber 3. A purification device 4 is installed at the connection between the inactivation chamber 3 and the pipes 32. An exhaust fan 41 is provided inside the purification device 4. A filter screen 42 is provided below the exhaust fan 41. The filter screen 42 is fixedly connected to the bottom inner wall of the purification device 4.

[0026] The curtain 31 seals the openings on both sides of the inactivation chamber 3 to prevent external bacteria and dust from entering the inactivation chamber 3. The purification device 4 replaces the air inside the inactivation chamber 3. The exhaust fan 41 discharges the dust and bacteria carried by the packaging bags required for cold chain to the outside. The filter 42 prevents external dust from entering the inactivation chamber 3 along the pipe 32.

[0027] The two assembly boxes of the inactivation box 3 are fixed by bolts. The upper interior of the two assembly boxes facing each other are respectively connected to a first lifting plate 5 and a second lifting plate 51. The first lifting plate 5 is located on the left side and the second lifting plate 51 is located on the right side. Several evenly distributed slots are provided on the lower right side of the first lifting plate 5, and several evenly distributed insert plates 52 are provided on the lower left side of the second lifting plate 51. The insert plates 52 are inserted into the slots, and the upper part of the insert plates 52 abuts against the bottom inner wall of the first lifting plate 5.

[0028] After the second lifting plate 51 is lifted upward, it drives the first lifting plate 5 to move upward through the insert plate 52, so that the first lifting plate 5 and the second lifting plate 51 move upward at the same distance.

[0029] Two sets of first springs 53 are respectively provided above the first lifting plate 5 and the second lifting plate 51. The lower end of the first spring 53 is fixedly connected to the upper part of the first lifting plate 5 and the second lifting plate 51, and the upper end of the first spring 53 is fixedly connected to the inner wall of the top of the inactivation box 3. A limiting rod 54 is provided on the inner side of the first spring 53.

[0030] Under the elastic force of the first spring 53, the first lifting plate 5 and the second lifting plate 51 slide downward to the lowest point in the initial state. Under the action of the limiting rod 54, the first lifting plate 5 and the second lifting plate 51 are prevented from falling off, and their sliding trajectory is restricted so that they remain parallel after sliding downward to the lowest point.

[0031] An inactivation device 6 is fixedly connected to the inner rear wall of the inactivation chamber 3 on one side. A connecting plate 57 is provided above the front side of the inactivation device 6. The upper part of the connecting plate 57 is fixedly connected to the inner top wall of the inactivation chamber 3. A roller 56 is provided in the middle of the lower part of the connecting plate 57. The roller 56 is rotatably connected in the middle of the connecting plate 57. A pull rope 55 is coiled on the outer wall above the roller 56. One end of the pull rope 55 is fixedly connected to the outer rear side of the first lifting plate 5 or the second lifting plate 51. The other end of the pull rope 55 is inserted into the inactivation device 6. A sliding groove is provided in the middle of the inactivation device 6. A slider 64 is provided in the sliding groove. A fixed frame 61 is provided on the front upper side of the inactivation device 6. A movable frame 62 is provided on the front side of the slider 64. Several evenly distributed plasma components 63 are provided below the fixed frame 61 and above the movable frame 62.

[0032] By using the pull rope 55, after the first lifting plate 5 and the second lifting plate 51 slide upward, the slider 64 is driven to slide vertically upward, causing the movable frame 62 to slide upward. This allows the fixed frame 61 and the movable frame 62 to come close to the packaging bag required for cold chain processing. The plasma component 63 then inactivates bacteria on the surface of the packaging bag, improving the surface inactivation effect. Furthermore, the structure of the roller 56 protects the pull rope 55, preventing it from rubbing against the inner wall of the inactivation device 6 and causing it to break. Example 3

[0033] The cold chain surface inactivation system disclosed in Embodiment 3 of the present invention has a structure that is basically the same as that in Embodiment 2. The difference is that a limiting plate is provided on the front side of the first support 2 and the upper rear side of the second support 21. A plurality of toothed grooves 24 are provided on the upper rear middle part of the first support 2. A first baffle 22 and a second baffle 23 are respectively provided at the rear ends of the toothed grooves 24. The first baffle 22 is located on the left rear side of the toothed groove 24, and the second baffle 23 is located on the right rear side of the toothed groove 24. Both the first baffle 22 and the second baffle 23 are configured as inclined structures with the left side facing outward and the right side facing inward.

[0034] The structure of the first baffle 22 and the second baffle 23 pushes the gear 8 inward, causing the gear 8 to mesh with the tooth groove 24, thereby driving the gear 8 to rotate.

[0035] A fixed post 85 is rotatably mounted on the lower rear side of the storage box 7 via a bearing. Several spline grooves are provided on the outer wall of the fixed post 85. A sliding post 83 is sleeved on the outer rear side of the fixed post 85. Several splines 84 are provided on the inner front side of the sliding post 83. The splines 84 engage with the spline grooves on the outer wall of the fixed post 85. The sliding post 83 and the fixed post 85 are horizontally slidably connected. The inner rear side of the sliding post 83 and the rear end of the fixed post 85 are respectively fixedly connected to the two ends of the second spring 86. A gear 8 is fixedly connected to the rear end of the sliding post 83. The gear 8 meshes with the tooth groove 24. A first helical gear 82 is fixedly mounted on the front side of the gear 8. A stop post 81 is fixedly connected to the middle rear side of the gear 8. The front end of the stop post 81 abuts against the inner walls of the first baffle 22 and the second baffle 23 respectively.

[0036] The spline 84 and spline groove interlocking structure allows the fixed post 85 and the sliding post 83 to slide relative to each other, preventing relative rotation. The extended abutment post 81 structure allows the abutment post 81 to push the gear 8 inward and mesh with the tooth groove 24 after it abuts against the first baffle 22 and the second baffle 23. Under the elastic force of the second spring 86, when the abutment post 81 is not in contact with the first baffle 22 and the second baffle 23, the gear 8 slides outward, so that the movement of the storage box 7 will not cause the gear 8 to rotate.

[0037] A sealing ring is provided on the lower outer side of the top cover 71. The top cover 71 is sealed to the upper part of the storage box 7 through the sealing ring. A placement rack 72 is fixedly connected to the lower part of the top cover 71. The placement rack 72 is a rod-shaped support structure. A connecting ring 73 is provided on the lower rear side of the top cover 71. The front side of the connecting ring 73 is fixedly connected to the outer wall of the middle rear side of the top cover 71. The front side of the first helical gear 82 meshes with the second helical gear 91 for transmission. The second helical gear 91 is fixedly installed at the bottom of the lifting assembly 9. The upper part of the second helical gear 91 is fixedly connected to the lower end of the reciprocating screw 92 through a shaft. A connecting ring 73 is sleeved on the outer side of the reciprocating screw 92. The connecting ring 73 is screwed to the reciprocating screw 92. A connecting frame 93 is sleeved on the shaft. The connecting frame 93 is rotatably connected to the shaft. The front end of the connecting frame 93 is fixedly connected to the outer rear side of the storage box 7.

[0038] When gear 8 and tooth groove 24 mesh, as the storage box 7 moves, gear 8 rotates, and the first helical gear 82 meshes with the second helical gear 91 to drive the reciprocating screw 92 to rotate. Since the connecting ring 73 is screwed to the reciprocating screw 92, the up and down movement of the connecting ring 73 is controlled, thereby controlling the opening and closing of the top cover 71. The placement rack 72 is used to place the packaging bags required for cold chain.

[0039] The specific solution is as follows: The conveyor 1 is started, moving the storage box 7. When it passes the first baffle 22, the abutment 81 drives the gear 8 to retract forward, causing the gear 8 to mesh with the tooth groove 24. As the storage box 7 continues to move, the gear 8 rotates, and the first helical gear 82 and the second helical gear 91 inside the gear 8 mesh, driving the reciprocating screw 92 to rotate. This causes the connecting ring 73 to move upward on the reciprocating screw 92, opening the top cover 71 and moving the placement rack 72 and the packaging bag above it upward. As the top cover 71 rises, it pushes the first lifting plate 5 and the second lifting plate 51 upward, causing the pull rope 55 to drive the slider 64 upward, thus moving the movable frame 62 upward. Since the first baffle 22 and the second baffle 23 are not continuous, after the gear 8 enters between them, it moves out of the tooth groove 24 under the elastic force of the second spring 86. The upper part pops out, and the first helical gear 82 and the second helical gear 91 separate, so that the upper cover 71 and the placement rack 72 slide horizontally at this height. At this time, the fixed rack 61 and the movable rack 62 are placed on the upper and lower sides of the packaging bag and are tightly fitted to the packaging bag. When the packaging bag passes horizontally between the fixed rack 61 and the movable rack 62, the plasma assembly 63 performs surface inactivation on the packaging bag. After the packaging bag passes through the plasma assembly 63, the abutment 81 abuts against the second baffle 23, causing the gear 8 to rotate again, and the first helical gear 82 and the second helical gear 91 mesh again, controlling the reciprocating screw 92 to rotate in the same direction again. At this time, the connecting ring 73 slides downward on the reciprocating screw 92 until the upper cover 71 and the storage box 7 are sealed and closed, completing the surface inactivation of the packaging bag.
