Description

Technical Field

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

[0002] Cold chain surface inactivation equipment is used to kill or inactivate viruses, bacteria and other microorganisms on the surface of cold chain goods.

[0003] In existing cold chain surface inactivation equipment, during the inactivation operation of cold chain items, there is a problem that when the cold chain items are transported by the conveyor equipment, the position of the cold chain items may be shifted, causing them to be unable to enter the cold chain surface inactivation equipment or causing blockage, resulting in poor working efficiency of the cold chain surface inactivation equipment.

[0004] A search revealed a Chinese patent document disclosing a cold chain surface inactivation device (Publication No.: CN222396990U). This utility model relates to the field of surface sterilization and inactivation technology, specifically a cold chain surface inactivation device, including a conveying mechanism, an inactivation mechanism, and an exhaust mechanism. The conveying mechanism uses a servo motor to drive an active roller, a driven roller, and a conveyor belt to achieve the conveying effect of cold chain goods. The inactivation mechanism includes a first plasma generator assembly, a second plasma generator assembly, and a third plasma generator assembly. In actual use, when frozen goods enter the inactivation mechanism via the conveyor belt, it achieves multi-directional inactivation of bacteria or viruses on the surface of the goods, improving the hygiene and safety of cold chain food. The exhaust mechanism, with its mounting slot, filter plate, and electric exhaust fan, allows the gas generated during the inactivation mechanism to pass through the filter plate, be drawn into the exhaust pipe connector by the electric exhaust fan, and then discharged from the work area through the exhaust pipe connector, thereby improving the working environment quality for operators. However, the following drawbacks still exist:

[0005] Although the aforementioned cold chain surface inactivation equipment achieves gas discharge from the work area, thereby improving the quality of the working environment for operators, it still has the problem that during the inactivation operation of cold chain items, the position of the cold chain items may be shifted when the conveyor equipment is transporting the cold chain items, causing them to be unable to enter the cold chain surface inactivation equipment or causing blockage, resulting in poor working efficiency of the cold chain surface inactivation equipment. Utility Model Content

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1

[0027] Please see Figure 1-4 This utility model provides a cold chain surface inactivation device, including a transmission device 1. A cold chain surface inactivation spray chamber 2 is fixedly connected to the top of the transmission device 1. Several atomizing nozzles for cold chain surface inactivation spraying are installed at the top of the interior of the cold chain surface inactivation spray chamber 2. The atomizing nozzles are connected to the bottom of the storage tank 3 through pipes. The storage tank 3 is fixedly connected to the top of the cold chain surface inactivation spray chamber 2. A first motor 7 is fixedly connected to the top of the storage tank 3, and the output end of the first motor 7 passes through the top of the storage tank 3 and extends into the interior of the storage tank 3 and is fixedly connected to the top of the main shaft 4. A connecting frame 5 is fixedly connected at equal intervals to the outer wall of the main shaft 4. A mixing plate 6 with several through holes is fixedly connected inside the connecting frame 5.

[0028] During cold chain surface inactivation operations, cold chain items are transported via conveyor 1. When the cold chain items enter the cold chain surface inactivation spray chamber 2, the inactivation liquid stored in the storage tank 3 is drawn by the atomizing nozzle and sprayed atomized, thereby completing the cold chain surface inactivation operation. The inactivation liquid stored in the storage tank 3 is then driven by the first motor 7 to rotate the main shaft 4, which in turn drives the connecting frame 5 and the mixing plate 6 to rotate, thoroughly mixing the inactivation liquid and preventing the components in the inactivation liquid from settling, which would result in poor inactivation effect.

[0029] A transfer pump 8 is fixedly connected to the top of the storage tank 3. The output end of the transfer pump 8 is connected to the top of the cold chain surface inactivation spray chamber 2. The input end of the storage tank 3 is fixedly connected to one end of the liquid inlet pipe 9, and the other end of the liquid inlet pipe 9 is fixedly connected to one end of the hose 10. A connector 11 is fixedly connected to the other end of the hose 10.

[0030] During use, when the inactivation liquid inside the storage tank 3 is insufficient, the connector 11 can be inserted into the container storing the inactivation liquid. The inactivation liquid is then delivered to the storage tank 3 via the transfer pump 8, the inlet pipe 9, and the hose 10. The hose 10 can be adapted to containers in different positions, making it more convenient to prepare the inactivation liquid.

[0031] Mounting brackets 13 are provided on both sides of the cold chain surface inactivation spray chamber 2. Connecting brackets 12 are installed on the top of the mounting brackets 13 on both sides. The bottom of the middle part of the connecting bracket 12 is fixedly connected to the top of the cold chain surface inactivation spray chamber 2. Sliding sleeves 14 are symmetrically slidably connected to the outer wall of the top of the connecting bracket 12. The bottom of the sliding sleeves 14 is fixedly connected to the top of the connecting block 15. A transmission screw sleeve 16 is fixedly connected through the inside of the connecting block 15. A connecting screw 17 is meshed through the inside of the transmission screw sleeve 16. The two connecting screws 17 inside the mounting bracket 13 are fixedly connected. The thread structure of the outer wall of the two connecting screws 17 is set with opposite structure. One end of one connecting screw 17 is connected to the output end of the second motor 18. The second motor 18 is fixedly connected to the outer wall of one end of the mounting bracket 13.

[0032] During use, depending on the size of the items to be surface-sterilized in the cold chain, the second motor 18 rotates forward or backward, driving the two connecting screws 17 to move synchronously. Because the thread structure on the outer side wall of the two connecting screws 17 is set in opposite directions, the transmission screw sleeve 16 drives the connecting block 15 to move relative to or opposite to each other. This causes the transmission rollers 24 and other components to move relative to or opposite to each other, so that the distance between the two sets of transmission rollers 24 after adjustment is adapted to the size of the items to be surface-sterilized in the cold chain, making the device unrestricted during use.

[0033] Each connecting block 15 has a connecting plate 19 fixedly connected to its bottom end. Each connecting plate 19 has a movable cavity 20 fixedly connected to its corresponding outer side wall at equal intervals. Each movable cavity 20 has a balloon 22 with an inflatable structure fixedly connected to one end inside. One end of the balloon 22 abuts against one end of the guide plate 21, and the end of the guide plate 21 near the balloon 22 is movably connected to one end of the movable cavity 20. The other end of the guide plate 21 is fixedly connected to a connecting frame 23 with an "L" shaped structure. Each of the two connecting frames 23 has a number of transmission rollers 24 at equal intervals at their corresponding ends. The top of the transmission rollers 24 is rotatably connected to the outer side wall of the connecting frame 23.

[0034] During use, the transfer roller 24 serves as an auxiliary transfer medium. This not only limits the movement of the items to be surface-sterilized in the cold chain, but also causes the transfer roller 24 to rotate when it comes into contact with the items, thus preventing poor transfer of the items. Furthermore, if the items collide with the transfer roller 24 due to instability of the transfer device 1, the transfer roller 24 will use the generated potential energy to push the guide plate 21 into the active cavity 20, squeezing the balloon 22 and dissipating the potential energy, thereby preventing damage to the items to be surface-sterilized in the cold chain.

[0035] The specific usage process in this embodiment is as follows:

[0036] First, based on the size of the items to be surface-sterilized in the cold chain, the second motor 18 rotates forward or backward, causing the components such as the conveyor rollers 24 to move relative to or in opposite directions, so that the distance between the two sets of conveyor rollers 24 after adjustment is adapted to the size of the items to be surface-sterilized in the cold chain.

[0037] Secondly, during use, the transfer roller 24 is used as an auxiliary transfer medium. This can limit the items to be surface-sterilized in the cold chain. When the items to be surface-sterilized in the cold chain come into contact with the transfer roller 24, the transfer roller 24 will rotate to assist in the transfer, thus avoiding poor transfer effect of the items to be surface-sterilized in the cold chain. When the items to be surface-sterilized in the cold chain collide with the transfer roller 24 due to the instability of the transfer device 1, the transfer roller 24 will push the guide plate 21 into the interior of the active cavity 20 with the generated potential energy, squeezing the balloon 22 and dissipating the potential energy.

[0038] Then, the cold chain items are transported through the transmission device 1. When the cold chain items enter the cold chain surface inactivation spraying chamber 2, the inactivation liquid stored in the storage tank 3 is drawn out by the atomizing nozzle and sprayed through atomization.

[0039] Finally, the first motor 7 drives the main shaft 4 to rotate, which in turn drives the connecting frame 5 and the mixing plate 6 to rotate, fully mixing the inactivating liquid. When the inactivating liquid inside the storage tank 3 is insufficient, the connector 11 can be inserted into the container storing the inactivating liquid. The inactivating liquid is then transferred to the storage tank 3 through the transfer pump 8 via the inlet pipe 9 and the hose 10. This completes the use of a cold chain surface inactivation device.
