Description

Technical Field

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

[0002] Cold chain logistics is a supply chain management model that uses temperature control technology to maintain a specific low-temperature environment, ensuring the stable quality of perishable and highly sensitive goods (such as food, pharmaceuticals, and biological products) throughout the entire process of production, storage, transportation, and distribution. It has strict requirements for delivery timeliness and typically uses a combination of air and land transportation to deliver goods to customers as quickly as possible.

[0003] Due to the special nature of cold chain logistics, the goods need to undergo one or more transfers and unloading processes when moving from air to land. During this period, although the goods are wrapped in foam insulated boxes, the airport ground temperature is extremely high in the summer, and the volume of goods is also large. The transfer and unloading process will accelerate the melting of the ice packs in the foam boxes, increasing the risk of spoilage. Conventional loading and unloading trolleys have obvious shortcomings in this regard and do not have the function of cooling and preventing spoilage.

[0004] Now, a new type of cold chain logistics transfer device is proposed to solve the above problems. Utility Model Content

The product is separated and placed on a rack. The bottom of the insulated box has track grooves at both the front and rear ends. The bottom of the track grooves is fixedly connected to a slide rail. The bottom right side of the support frame is movably connected to the front and rear ends of the support frame. The bottom of the sealed door is fixedly connected to a support bar. The bottom of the support bar is movably connected to the front and rear ends of the support bar. The upper and lower ends of the right side of the sealed door are fixedly connected to steel bars. The upper and lower ends of the left side of the insulated box are fixedly installed with electromagnets. The right side of the insulated box is equipped with a cooling component to facilitate cooling and prevent deterioration.

[0007] The cooling component includes a semiconductor refrigeration chip, which is fixedly connected to the inside of the right side of the insulation box. A first metal heat sink is fixedly connected to the left side of the semiconductor refrigeration chip, and four sets of first fans are fixedly installed on the left side of the first metal heat sink. A second metal heat sink is fixedly connected to the right side of the semiconductor refrigeration chip, and four sets of second fans are fixedly installed on the right side of the second metal heat sink. A rechargeable lithium battery pack is fixedly connected to the bottom of the inside of the outer fixing frame.

[0008] As a further technical solution of this utility model, the left side of the semiconductor cooling chip is flush with the right side of the interior of the insulation box, and the semiconductor cooling chip penetrates both the inner and outer surfaces of the insulation box.

[0009] As a further technical solution of this utility model, the front and rear ends of the semiconductor cooling chip and the first metal heat sink are flush, and the upper and lower ends of the semiconductor cooling chip and the first metal heat sink are flush.

[0012] As a further technical solution of this utility model, the positions and dimensions of the steel bars and electromagnets correspond one-to-one, and the PLC controller and electromagnets are electrically connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the cold chain logistics transfer device not only realizes the function of cooling and preservation, but also realizes the function of easy and quick loading and unloading, and also realizes the function of easy locking and sealing.

[0014] (1) By setting up a semiconductor cooling chip, a first metal radiator, a first fan, a second metal radiator and a second fan, when in use, the goods are placed in a placement rack made up of a support frame and an item separation placement frame. After the placement rack is pushed into the insulated box and sealed, it can be pushed and pulled to the next loading point by the bottom frame. When the semiconductor cooling chip is powered on, one side cools and the other side heats up. The side where the first metal radiator is located is the cooling side. The surface temperature of the first metal radiator drops rapidly. The first fan blows the first metal radiator and quickly diffuses the low-temperature cold air into the interior of the insulated box, keeping it in a low-temperature state and reducing the impact of the external high temperature on the goods. The side where the second metal radiator is located is the heating side. The second metal radiator conducts heat outward.

The bracket and load-bearing pulley support the left side of the rack, and the support pulley supports its right side. At the same time, it slides along the slide rail in the track groove, making it easier to pull out and realizing the function of easy and quick loading and unloading.

[0016] (3) By setting up a sealing door, steel bars and electromagnets, when sealing is required, the sealing door is pushed towards the heat preservation box so that the steel bars and electromagnets fit tightly together. The electromagnets are energized and magnetized by the PLC controller, so that the sealing door can be firmly attracted to achieve sealing. When opening is required, the electromagnets are de-energized and demagnetized by the PLC controller, so that the sealing door can be opened. This realizes the function of easy locking and sealing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figure 1-4 A cold chain logistics transfer device includes a bottom frame 1, an insulated box 2 fixedly connected to the top of the bottom frame 1, an outer fixed frame 3 fixedly connected to the right side of the insulated box 2, a PLC controller 10 fixedly connected to the front end of the outer fixed frame 3, wheel sets 11 installed on both sides of the bottom of the bottom frame 1, a sealing door 17 provided on the left side of the insulated box 2, handles 18 fixedly connected to the front and rear ends of the left side of the sealing door 17, a support frame 19 fixedly connected to the right side of the sealing door 17, an item separation rack 20 welded and fixed inside the support frame 19, and a cooling component for facilitating cooling and preventing deterioration provided on the right side of the insulated box 2.

[0024] Please see Figure 1-4 A cold chain logistics transfer device also includes a cooling component, which includes a semiconductor cooling chip 4. The semiconductor cooling chip 4 is fixedly connected to the inside of the right side of the insulation box 2. A first metal radiator 5 is fixedly connected to the left side of the semiconductor cooling chip 4. Four sets of first fans 6 are fixedly installed on the left side of the first metal radiator 5. A second metal radiator 7 is fixedly connected to the right side of the semiconductor cooling chip 4. Four sets of second fans 8 are fixedly installed on the right side of the second metal radiator 7. A rechargeable lithium battery pack 9 is fixedly connected to the bottom of the inner side of the outer fixing frame 3.

[0025] The left side of the thermoelectric cooler 4 is flush with the right side inside the insulation box 2. The thermoelectric cooler 4 runs through both the inner and outer sides of the insulation box 2. The front and rear ends of the thermoelectric cooler 4 and the first metal heat sink 5 are flush with each other. The top and bottom ends of the thermoelectric cooler 4 and the first metal heat sink 5 are flush with each other. There is a distance between the left side of the first fan 6 and the right side of the support frame 19, and the two do not contact each other. The thermoelectric cooler 4, the first fan 6, the second fan 8, and the PLC controller 10 are electrically connected to prevent the goods from deteriorating rapidly through internal cooling.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, when the semiconductor cooling chip 4 is powered on, one side cools and the other side heats up. The side where the first metal heat sink 5 is located is the cooling side. The surface temperature of the first metal heat sink 5 drops rapidly. The first fan 6 blows on the first metal heat sink 5, rapidly diffusing the low-temperature cold air into the interior of the insulation box 2, keeping it in a low-temperature state and reducing the impact of external high temperature on the goods. The side where the second metal heat sink 7 is located is the heating side. The second metal heat sink 7 conducts heat outward. The second fan 8 blows on the second metal heat sink 7, accelerating the dissipation of heat.

[0027] The bottom of the insulated box 2 is provided with track grooves 12 at the front and rear ends. The bottom of the track groove 12 is fixedly connected to the slide rail 13. The bottom right side of the support frame 19 is movably connected to the front and rear ends of the support pulley 14. The bottom of the sealed door 17 is fixedly connected to the support bar 15. The bottom of the support bar 15 is movably connected to the front and rear ends of the load-bearing pulley 16. The bottom ends of the wheel assembly 11 and the load-bearing pulley 16 are flush. The slide rail 13 and the support pulley 14 are matched in shape and size. The support pulley 14 can slide left and right along the top of the slide rail 13 for easy loading and unloading.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the storage rack consisting of the support frame 19 and the item divider rack 20 is used to store materials. It is open at the front and back, which facilitates simultaneous loading and unloading by multiple workers. When unloading, grab the handle 18 and pull the sealing door 17 to the left. The storage rack is then pulled out from inside the insulated box 2. The support bar 15 and the load-bearing pulley 16 support the left side of the storage rack, and the support pulley 14 supports its right side. At the same time, it slides along the slide rail 13 in the track groove 12, making it easier to pull out.

[0029] Steel bars 21 are fixedly connected to the inside of the upper and lower ends of the right side of the sealing door 17, and electromagnets 22 are fixedly installed inside the upper and lower ends of the left side of the insulation box 2. The positions and dimensions of the steel bars 21 and electromagnets 22 correspond one-to-one. The PLC controller 10 and electromagnets 22 are electrically connected to facilitate quick sealing.

[0030] Specifically, such as Figure 2and Figure 3 As shown, when sealing is required, the sealing door 17 is pushed towards the insulation box 2, so that the steel strip 21 and the electromagnet 22 fit tightly together. The electromagnet 22 is energized and magnetized by the PLC controller 10, which can firmly attract the sealing door 17 to achieve sealing. When opening is required, the electromagnet 22 is de-energized and demagnetized by the PLC controller 10, which can open the sealing door 17.

[0031] Working principle: When using this utility model, firstly, the goods are placed in the placement rack consisting of the support frame 19 and the item separation rack 20. After the placement rack is pushed into the insulated box 2 and sealed, it can be pushed and pulled to the next loading point by the bottom frame 1. After the semiconductor cooling chip 4 is powered on, one side cools and the other side heats up. The side where the first metal heat sink 5 is located is the cooling side. The surface temperature of the first metal heat sink 5 drops rapidly. The first fan 6 blows the first metal heat sink 5, which quickly diffuses the low-temperature cold air into the interior of the insulated box 2, keeping it in a low-temperature state and reducing the impact of the external high temperature on the goods. The side where the second metal heat sink 7 is located is the heating side. The second metal heat sink 7 conducts heat outward. The second fan 8 blows the second metal heat sink 7, which accelerates the dissipation of heat. The storage rack, consisting of the support frame 19 and the item divider rack 20, is used to store materials. It is open at both ends, facilitating simultaneous loading and unloading by multiple workers. During unloading, the handle 18 is grasped, and the sealing door 17 is pulled to the left, thus removing the storage rack from the insulation box 2. The support bar 15 and load-bearing pulley 16 support the left side of the storage rack, while the support pulley 14 supports its right side. Simultaneously, the rack slides along the slide rail 13 within the track groove 12, making the pulling easier. When sealing is required, the sealing door 17 is pushed towards the insulation box 2, causing the steel bar 21 and electromagnet 22 to fit tightly together. The PLC controller 10 controls the electromagnet 22 to be energized and magnetized, firmly attracting the sealing door 17 to achieve a seal. To open, the PLC controller 10 controls the electromagnet 22 to be de-energized and demagnetized, allowing the sealing door 17 to be opened.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
