Description

Technical Field

[0001] The present invention relates to the technical field of cold chain logistics, and in particular to adjustable temporary storage equipment for cold chain logistics. Background Art

[0002] Frozen logistics, that is, the part of cold chain logistics involving freezing, mainly refers to a series of logistics activities such as storage, transportation, and distribution of items that need to be frozen in a low-temperature environment to ensure the quality and safety of the items. For perishable foods such as meat, seafood, frozen foods, etc., frozen logistics can maintain a low temperature throughout the supply chain, delay food spoilage, and extend the shelf life of food. For example, frozen seafood can be stored at temperatures below -18°C for several months or even longer, while it will quickly deteriorate at room temperature. To ensure the taste and nutritional value of food, low temperature can slow down the activity of enzymes and the growth of microorganisms in food, thereby maintaining the original flavor and nutritional components of food. Many medicines, especially biological products and vaccines, are very sensitive to temperature. Drugs are sensitive and need to be transported and stored under strict freezing conditions. Frozen logistics can ensure that these drugs remain stable within the specified temperature range to ensure the effectiveness and safety of the drugs. For example, vaccines usually need to be stored at temperatures below -20°C to prevent them from becoming ineffective and meet drug regulatory requirements. Drug regulatory authorities have strict regulations on the cold chain logistics of drugs. Frozen logistics is an important means to ensure that drugs meet regulatory requirements. Frozen logistics enables perishable foods and drugs to be transported and traded globally. Through advanced freezing technology and logistics management, high-quality food and drugs from different regions can be delivered to all parts of the world to meet consumer demand. For example, imported seafood and fruits can maintain their freshness through frozen logistics and enter the domestic market.

[0003] However, the current ones have the disadvantages of not being able to meet people's needs.

[0004] 1. Cold chain materials are generally stored in cold storage. High-temperature cold storage is generally used to store fruits and vegetables, etc., and the temperature is usually between 0℃-10℃. Medium-temperature cold storage is mainly used to store meat, seafood, etc., and the temperature range is generally between 10℃-18℃. Low-temperature cold storage is used to store ice cream, quick-frozen food, etc., and the temperature can be as low as 25℃ or below. Logistics is divided into delivery stations and transfer stations, and transfer stations are divided into large-piece outlets and small-piece outlets. The manual handling speed is relatively slow, especially for frozen items. Due to their heavy weight and low temperature, the handling process is more time-consuming. It may take several minutes to carry a box of frozen food. In large-scale logistics operations, this inefficiency will lead to backlogs and delays in goods. Manual operations are prone to errors, such as mixing items of different specifications and mislabeling. Due to the influence of human factors, small frozen items are often mixed with oversized items, which may cause problems in subsequent storage and transportation links, such as damage to other items and occupying too much space.

[0005] 2. Cold chain materials are stored in cold storage due to manual handling. It is difficult for storage equipment to accurately grasp the order of inventory items, which is not conducive to effective inventory management. For cold chain items with a short shelf life, some items will expire and be wasted due to the inability to determine the first-in-first-out order. For example, in traditional mobile cold storage, since it is impossible to determine the order of storage time of items, the first stored items will be piled up at the bottom, and the later stored items will be taken out and used first, causing the first stored items to expire and cause losses;

[0006] 3. Storage equipment with a fixed height cannot make full use of the space. If the equipment is too high, it will lead to a waste of upper space, because the operator may not be able to effectively use the excessively high space to store items; if the equipment is too low, the space utilization rate may be low and it may not be able to meet the storage needs of a large number of items. For example, in a small cold chain logistics warehouse, a refrigerator that is too high may make the top space unusable, and if the equipment is too low, it may not be able to store enough goods. At the same time, the shelves are low and the height cannot be adjusted, resulting in some higher frozen items being unable to be placed in the temporary storage cabinet, which limits the space of the frozen storage cabinet. Summary of the invention

[0018] The present invention provides an adjustable temporary storage device for cold chain logistics, which has the following beneficial effects:

[0019] The adjustable temporary storage equipment for cold chain logistics and the automatic conveying system can run continuously at a stable speed and quickly transport cold chain items from one location to another, greatly shortening the transportation time. Compared with traditional manual transportation, automatic transportation can handle a large number of items in a shorter time, improving the overall efficiency of logistics. For example, in a cold chain warehouse, the automatic conveying device can transport a batch of frozen foods from the warehousing area to the storage area within a few minutes, while manual transportation may take dozens of minutes or even longer.

[0020] The adjustable temporary storage equipment for cold chain logistics measures the height of materials and classifies and stores them according to their sizes, which can make the items in the frozen storage cabinet more neatly and orderly. Items of different sizes are reasonably allocated space to avoid space waste caused by chaotic stacking. Smaller items can be arranged closely, while larger items can occupy appropriate space alone, thereby improving the overall storage efficiency of the storage cabinet and ensuring that only items that meet the storage height enter the frozen storage cabinet, which can maximize the use of storage space and avoid idle or inadequate use of space caused by mixing items of different sizes. For cold chain logistics companies, this means that more goods can be stored in the same storage space, reducing storage costs, avoiding mixing of frozen items of different sizes, and reducing squeezing and collision between items, especially for some fragile or squeezing-sensitive frozen items, such as frozen fruits, seafood, etc. This classified storage method can effectively reduce the risk of damage to goods. At the same time, a reasonable storage layout also helps to maintain a uniform temperature in the frozen storage cabinet, ensuring that all items can be stored in a suitable temperature environment, further ensuring the quality of the goods.

[0021] The adjustable temporary storage equipment for cold chain logistics unloads materials in sequence according to the storage time to ensure that the frozen items that enter first are taken out for use or transportation first, which complies with the first-in-first-out principle in cold chain logistics. For example, in the food cold chain, the food that enters the warehouse first is shipped first, which can ensure that the food is consumed within the shelf life to the greatest extent, reduce the risk of expiration and deterioration, ensure food safety, avoid long-term backlog of items in storage cabinets, and reduce the quality degradation problem caused by long storage time. For example, some medicines or vaccines that are sensitive to the storage period can be used in time within the validity period in this way to ensure their efficacy and safety. The storage cabinets are staggered in sequence and are equipped with an automatic unloading structure. The staff does not need to search for specific items in the storage cabinets, and the storage and retrieval of goods is more convenient, especially when the cargo volume is large and the storage and retrieval are frequent. It can save a lot of time and labor costs and improve the overall efficiency of logistics operations.

[0022] The adjustable temporary storage equipment for cold chain logistics has a control panel that sets a reasonable measuring height and uses a displacement sensor for detection. It can accurately determine whether the size of the frozen items meets the storage requirements, which avoids errors in manual judgment and ensures that only items of appropriate size enter the storage cabinet, improving storage accuracy. For example, in the cold chain logistics of medicines, medicines of different specifications need to be stored strictly according to size. The equipment can accurately screen out medicines that meet the requirements and avoid storage confusion and errors caused by size inconsistency. The adjustment structure and the second displacement sensor inside the storage cabinet can adjust the height of the internal shelves of the storage cabinet according to the instructions of the control panel. The storage cabinet is provided with an adjustment structure. The height can be adjusted according to the height displayed above. Each shelf can be adjusted. The second displacement sensor will transmit all shelf adjustment information back to the control panel. The control panel transmits the height of the frozen items detected by the first displacement sensor based on the second displacement sensor information technology, so that the measured size is consistent and enters the storage cabinet.

[0023] The adjustable temporary storage equipment for cold chain logistics, the temperature controller can accurately adjust the refrigeration power of the semiconductor flat refrigeration plate, thereby providing a stable low-temperature environment for frozen items. Compared with traditional refrigeration methods, semiconductor refrigeration can achieve more precise temperature control and reduce temperature fluctuations. For some temperature-sensitive drugs or biological products, precise temperature control can ensure their quality and effectiveness. During storage, temperature fluctuations may cause changes in the active ingredients of the drugs and affect the efficacy. The semiconductor flat refrigeration plate with the temperature controller can control the temperature fluctuations within a very small range, providing reliable storage conditions for frozen items. Different temperatures can be set through the temperature controller according to the requirements of different frozen items. This allows the same storage cabinet to store multiple items with different temperature requirements at the same time, improving the versatility and flexibility of the equipment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] See also Figures 1 to 8 The present invention provides a technical solution: an adjustable temporary storage device for cold chain logistics, comprising a storage box 1, a temperature controller 13 is installed on one side of the storage box 1 by screws, a sensing rod 14 is connected to one side of the temperature controller 13 by a cable, a semiconductor flat refrigeration plate 10 is installed on the inner back plate of the storage box 1 by screws, a third mounting plate 5 is installed on one side of the storage box 1 by screws, a fixing frame 6 is provided on one side of the third mounting plate 5, a door panel 11 is magnetically attracted in front of the storage box 1, an observation window 12 is embedded in the door panel 11, a blanking plate 15 is installed on the top of the storage box 1 by screws, a slide plate 2 is welded on one side of the storage box 1, a support plate 4 is installed on the top of the slide plate 2 by screws, a connecting plate 3 is installed on the rear of the slide plate 2 by screws, a base of a third servo motor 8 is installed on the rear of the connecting plate 3 by screws, a shell of a second servo motor 7 is installed on the rear of the storage box 1 by screws, and a control panel 9 is installed on one side of the storage box 1 by screws.

[0037] In this embodiment, Figure 1 and Figure 3As shown, the internal hole groove of the slide plate 2 is slidably connected with the movable bracket 202, and the first fixed bracket 203 and the second fixed bracket 204 are respectively installed on the front of the slide plate 2 by screws, and the second fixed bracket 204 is provided below the first fixed bracket 203, and the proximity switch 201 is installed above the first fixed bracket 203 by screws, and a plurality of connecting rods are provided between the first fixed bracket 203 and the second fixed bracket 204, and the connecting rods are evenly arranged horizontally, and a plurality of connecting rods are provided inside the movable bracket 202, and the connecting rods are evenly arranged horizontally, and when the first fixed bracket 203 and the second fixed bracket 204 intersect with the connecting rod of the movable bracket 202 respectively, the connecting rod of the first fixed bracket 203 and the connecting rod of the movable bracket 202 will be in a crossed and staggered state, and at the same time, the connecting rod of the second fixed bracket 204 and the connecting rod of the movable bracket 202 will also be crossed and staggered; the sliding connection between the internal hole groove of the slide plate 2 and the movable bracket 202 is cold The mobile bracket 202 can smoothly move along the slide plate 2 to ensure that the frozen items will not shake or fall during the transportation process, thereby ensuring the safety of the items. For example, when the frozen items are transported from one storage area to another, the mobile bracket 202 can carry the items and slide smoothly on the slide plate 2 to accurately transport the items to the destination. The connecting rod of the mobile bracket 202 is cross-distributed with the connecting rod of the second fixed bracket 204, so that the mobile bracket 202 can transfer the frozen items of the second fixed bracket 204 to the first fixed bracket 203, and the mobile bracket 202 can continue to transport the frozen items. The proximity switch 201 above the first fixed bracket 203 can detect the position of the frozen items and provide a signal for the automatic control system. When the frozen items approach or reach a specific position, the proximity switch 201 triggers a signal, and the control system can perform corresponding operations according to this signal to stop the transmission, which is convenient for cooperating with the detection component for detection.

[0038] In this embodiment, Figure 2 and Figure 4 As shown, a first sprocket 301 is installed inside the connecting plate 3, and the first sprocket 301 and the second sprocket 303 are connected by a chain 302, and the chain 302 forms a rotating structure through the second sprocket 303, and the first sprocket 301 forms a rotating structure through the chain 302; when it is necessary to start the transmission, the first sprocket 301 can be driven to rotate by an external power device, and after the first sprocket 301 rotates, it drives the chain 302 to move. Since the chain 302 and the second sprocket 303 form a transmission connection, the movement of the chain 302 will cause the second sprocket 303 to start rotating, thereby realizing the first sprocket 301 forming a rotating structure through the chain 302, and at the same time, the chain 302 forms a rotating structure through the second sprocket 303, and the chain 302 can drive the slider and the anti-fall device connected to the fixed movable bracket 202 to move, so as to transport frozen items.

[0039] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a first mounting plate 402 is installed on the top of the support plate 4 by screws, a first cylinder 403 is installed in front of the first mounting plate 402 by screws, a first displacement sensor 401 is installed on the output shaft of the first cylinder 403 by bolts, a second mounting plate 404 is installed on the top of the support plate 4 by screws, a second cylinder 405 is installed on one side of the second mounting plate 404 by screws, a third cylinder 406 is installed on the output shaft below the second cylinder 405 by bolts, and a third cylinder 406 is installed on one side of the output shaft by bolts. The push plate 407 and the first displacement sensor 401 form a vertical sliding structure through the first cylinder 403, and the third cylinder 406 forms a vertical structure through the second cylinder 405, and the push plate 407 forms a horizontal sliding structure through the third cylinder 407; when the frozen object is transferred to the first fixed bracket 203, the first cylinder 403 is started to push the first displacement sensor 401 downward, so that the first displacement sensor 401 is close to the frozen object, and the height of the frozen object is detected. The detection result shows that the height of the frozen object does not meet the requirements of the input According to the requirement of entering the storage box 1, the transmission component will be connected to the control panel 9, and the control panel 9 will issue an instruction to make the transmission object run in the opposite direction and return to the initial position. At this time, since the second object to be detected has not been placed on the transmission movable bracket 202, it is not affected here. The object with inconsistent height returns to the starting position second fixed bracket 204, and then stops the transmission equipment, waiting for the operator to remove the frozen object that does not meet the standard. The frozen object meets the standard, the second cylinder 405 is started, driving the third cylinder 406 to move vertically downward to the appropriate position, and then the third cylinder 406 is started to push the push plate 407 to slide horizontally, and the frozen object that meets the standard is pushed into the unloading plate 15 to enter the storage box 1. It is used to distinguish whether the size set at the beginning of the storage box 1 and the height of the frozen object in the transmission process meet the height set for entering the storage box 1. There are two transmission modes. The intermittent mode is mainly used to detect whether the heights of different frozen objects are the same, which is convenient for warehousing. The continuous mode is suitable for frozen objects of the same size in the same batch, which can be quickly put into storage. At this time, it is necessary to stop using the detection mode.

[0040] In this embodiment, Figure 1 and Figure 6As shown, a slide bar 504 is welded on the top of the third mounting plate 5, and a moving block 503 is attached to the inside of the slide bar 504. A fourth mounting plate 501 is installed on the top of the moving block 503 by screws. A socket 502 is opened inside the fourth mounting plate 501. The middle part of the moving block 503 is threadedly connected with the screw rod 505. A fifth mounting plate 507 is welded on the top of the slide bar 504. A second displacement sensor 506 is installed in front of the fifth mounting plate 507 by screws, and the moving block 503 forms a sliding structure with the slide bar 504 through the screw rod 505. The height of the shelf inside the storage box 1 can be adjusted according to the same batch of frozen goods of different sizes, which enables the temporary storage equipment to better adapt to frozen goods of different specifications, improves space utilization and storage flexibility. For example, when there is a batch of larger When large-sized frozen items need to be stored, the height of the shelves can be adjusted to provide them with suitable storage space to avoid storage failure or waste of space due to size mismatch. To determine the size of the same batch of frozen items, the size information can be obtained through measuring tools or known item specifications. According to the size of the item, the shelf height adjustment device is started. The rotation of the screw rod 505 can usually be started through a control system or manual operation. When the screw rod 505 rotates, the moving block 503 threadedly connected thereto slides on the slide bar 504. The movement of the moving block 503 drives the fourth mounting plate 501 and the shelf connected thereto to move up and down, thereby adjusting the shelf height. Observe the reading of the second displacement sensor 506 to ensure that the shelf is adjusted to a suitable height to accommodate the frozen items and leave appropriate space.

[0041] In this embodiment, Figure 1 and Figure 7As shown, an insertion rod 604 is welded at the bottom of the fixing frame 6, and a first driving shaft 603 is rotatably connected inside the fixing frame 6. A shell of a first servo motor 601 is installed on one side of the fixing frame 6 by screws, and a synchronous belt 602 is attached to the outer wall of one end of the first driving shaft 603, and a plurality of horizontally distributed first driving shafts 603 are arranged inside the fixing frame 6, and the first driving shafts 603 form a rotating structure through the output shaft of the first servo motor 601, and two first driving shafts 603 are connected by a synchronous belt 602; the first servo motor 601 drives the first driving shaft 603 to rotate, and the first driving shafts 603 are connected by the synchronous belt 602, so that multiple first driving shafts 603 rotate synchronously, thereby realizing automatic unloading of frozen items above the layer plate. This function greatly improves the efficiency of unloading and reduces the time and labor intensity of manual operation. For example, in a large-scale cold chain logistics center, the shelves in the frozen storage box 1 can quickly and automatically transport the frozen items to the next link, thereby improving the overall speed of logistics. Since multiple first drive shafts 603 rotate synchronously, the frozen items can be automatically arranged neatly on the shelves, which is not only convenient for management and storage, but also improves space utilization. For example, frozen items of different sizes can be classified and arranged by rotating the first drive shaft 603, which is convenient for subsequent transportation and distribution. The automatic unloading and arrangement functions can reduce the occurrence of human errors and improve the accuracy and reliability of logistics. At the same time, the precise control of the first servo motor 601 can ensure that the delivery speed and position of the frozen items are accurate. For example, in cold chain logistics, for temperature-sensitive frozen items, accurate delivery and arrangement can reduce temperature fluctuations and ensure the quality and safety of the items.

[0042] In this embodiment, Figure 2 and Figure 8 As shown, the output shaft on one side of the second servo motor 7 is rotatably connected to the second gear 702, one side of the second gear 702 is meshed with the first gear 701, the interior of the first gear 701 is rotatably connected to the rotating shaft 703, one end of the rotating shaft 703 is plugged with a cover plate 704, and the cover plate 704 forms a rotating structure through the rotating shaft 703, and the rotating shaft 703 forms a rotating structure through the first gear 701, and the second gear 702 forms a rotating structure through the first gear 701, and the second gear 702 forms a rotating structure through the second servo motor 7 Rotation structure: start the second servo motor 7, the second servo motor 7 drives the second gear 702 on the output shaft on one side thereof to rotate, the second gear 702 engages with the first gear 701, causing the first gear 701 to rotate, the first gear 701 drives the internal rotating shaft 703 to rotate, the rotating shaft 703 then drives the cover 704 to rotate and open, at this time the frozen goods can be transported, after the transport is completed, reverse the above steps to close the cover 704, thereby ensuring the sealing of the frozen storage box 1 and maintaining the low temperature environment of the cold chain logistics.

[0043] In this embodiment, Figure 2 and Figure 4 As shown, the second sprocket 303 forms a rotating structure through the third servo motor 8; after the third servo motor 8 is started, its output shaft generates rotational power, which is transmitted to the second sprocket 303 through a specific transmission mechanism, a coupling. Since the first sprocket 301 and the second sprocket 303 are connected by a chain 302, when the third servo motor 8 drives the second sprocket 303 to rotate, the chain 302 starts to move, and the movement of the chain 302 drives the first sprocket 301 to rotate. In this way, under the drive of the third servo motor 8, the second sprocket 303 rotates, and the first sprocket 301 is driven to rotate synchronously through the chain 302, thereby realizing the rotating structure of the second sprocket 303 formed by the third servo motor 8.

[0044] In this embodiment, Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8 As shown, a plurality of cable connections are provided on one side of the control panel 9, and the control panel 9 is connected to the third servo motor 8 and to the first cylinder 403, and to the first displacement sensor 401 and to the second cylinder 405, and to the third cylinder 406 and to the temperature controller 13 and the control panel 9, and to the control panel 9 and the semiconductor flat refrigeration plate 10 and to the second servo motor 7 and the control panel 9, and to the second displacement sensor 506 and to the first servo motor 601 and the control panel 9; when a certain operation is required, such as opening the upper cover plate 704 of the frozen storage box 1, the control panel 9 sends a command to the second servo motor 7, the second servo motor 7 is started, and the output shaft on one side thereof drives the second gear The wheel 702 rotates, and the second gear 702 engages with the first gear 701 to rotate the first gear 701, thereby driving the rotating shaft 703 and the cover 704 to rotate and open. If it involves the transmission or position adjustment of the object, the control panel 9 can control the operation of the first servo motor 601, the third servo motor 8 and other motors to drive the corresponding transmission mechanism or adjust the position of the component. At the same time, the first displacement sensor 401 and the second displacement sensor 506 monitor the position of the relevant components in real time, and feed back the position data to the control panel 9 so that the control panel 9 can perform precise control. When it is necessary to adjust the temperature in the frozen storage box 1, the temperature controller 13 transmits the temperature information to the control panel 9. The control panel 9 controls the refrigeration intensity of the semiconductor flat refrigeration plate 10 according to the temperature conditions, or adjusts the position of the refrigeration component by controlling the relevant cylinder action, etc., to maintain a suitable low-temperature environment in the frozen storage box 1.

[0045] In this embodiment, Figure 1and Figure 2 As shown, the external structural dimensions of one side of the door panel 11 are consistent with the internal external structural dimensions of the storage box 1, and a magnetic sheet is embedded in the side where the door panel 11 fits with the storage box 1; when frozen items need to be placed in the storage box 1, confirm that the door panel 11 is in a closed state and fits tightly with the storage box 1, and the external structural dimensions of one side of the door panel 11 are consistent with the internal external structural dimensions of the storage box 1, ensuring good sealing. A magnetic sheet is embedded in the side where the door panel 11 fits with the storage box 1, and the magnetic effect is utilized to enable the door panel 11 to be firmly adsorbed on the storage box 1, further enhancing the sealing effect and preventing external hot air from entering the storage box 1 and affecting the quality of frozen items. A magnetic sheet is embedded in the side where the door panel 11 fits with the storage box 1, and the magnetic effect is utilized to enable the door panel 11 to be firmly adsorbed on the storage box 1, further enhancing the sealing effect and preventing external hot air from entering the storage box 1 and affecting the quality of frozen items.

[0046] In summary, the adjustable temporary storage equipment for cold chain logistics is used. When in use, the upper cover 704 of the frozen storage box 1 is opened, and the control panel 9 sends a command to the second servo motor 7. The second servo motor 7 is started, and the output shaft on one side drives the second gear 702 to rotate. The second gear 702 engages with the first gear 701 to rotate the first gear 701, thereby driving the rotating shaft 703 and the cover 704 to rotate and open. At this time, the frozen items can be transported. After all the frozen items have been transported, the above steps are reversed to close the cover 704 to ensure the sealing of the frozen storage box 1 and maintain the low temperature environment of the cold chain logistics. The third servo motor 8 drives the first sprocket 301 to rotate. After the first sprocket 301 rotates, it drives the chain The chain 302 moves, and since the chain 302 and the second sprocket 303 form a transmission connection, the movement of the chain 302 will cause the second sprocket 303 to start rotating, so that the first sprocket 301 forms a rotating structure through the chain 302, and the chain 302 forms a rotating structure through the second sprocket 303. The chain 302 can drive the slider and the anti-fall device connected to the fixed mobile bracket 202 to move, and transfer the frozen objects. The connecting rod of the mobile bracket 202 and the connecting rod of the second fixed bracket 204 are cross-distributed, so that the mobile bracket 202 can transfer the frozen objects of the second fixed bracket 204 to the first fixed bracket 203. The proximity switch 201 above the first fixed bracket 203 can detect the position of the frozen objects, which is an automatic control system. The system provides a signal. When the frozen object approaches or reaches a specific position, the proximity switch 201 triggers a signal. When the frozen object is transferred to the first fixed bracket 203, the first cylinder 403 is started to push the first displacement sensor 401 downward, so that the first displacement sensor 401 is close to the frozen object, and the height of the frozen object is detected. The detection result shows that the height of the frozen object does not meet the requirements for entering the storage box 1. The transmission component will be connected to the control panel 9, and the control panel 9 will issue an instruction to run in the opposite direction of the conveyed object and return to the initial position. At this time, since the second object to be detected has not been placed on the transmission movable bracket 202, it is not affected here. The object that does not meet the height requirement returns to the second fixed bracket 204 at the starting position, and then stops transmitting. The transport device waits for the operator to take down the frozen items that do not meet the standards. When the frozen items meet the standards, the second cylinder 405 is started, driving the third cylinder 406 to move vertically downward to a suitable position. Then the third cylinder 406 is started to push the push plate 407 to slide horizontally, pushing the frozen items that meet the standards into the unloading plate 15 so that they enter the storage box 1. It is used to distinguish whether the size set at the beginning of the storage box 1 and the height of the frozen items in the transport process meet the height set for entering the storage box 1. There are two transport modes. The intermittent mode is mainly used to detect whether the heights of different frozen items are the same, which is convenient for warehousing. The continuous mode is suitable for frozen items of the same size in the same batch, which can be quickly put into storage. At this time, it is necessary to stop using the detection mode.The height of the shelves inside the storage box 1 can be adjusted according to the frozen items of the same batch of different sizes. To determine the size of the frozen items of the same batch, the size information can be obtained through measuring tools or known item specifications. According to the size of the item, the shelf height adjustment device is started, and the screw rod 505 is started manually to rotate. When the screw rod 505 rotates, the moving block 503 threadedly connected thereto slides on the slide bar 504. The movement of the moving block 503 drives the fourth mounting plate 501 and the shelf connected thereto to move up and down, thereby adjusting the shelf height. Observe the reading of the second displacement sensor 506 to ensure that the shelf is adjusted to a suitable height to accommodate the frozen items and leave appropriate space. The first servo motor 601 drives the first drive shaft 603 to rotate, and the first drive shafts 603 are connected through the synchronous belt 602 to make the multiple first drive shafts 603 rotate synchronously, thereby realizing the automatic unloading of frozen objects on the layer plate. Since the multiple first drive shafts 603 rotate synchronously, the frozen objects can be automatically arranged neatly on the layer plate, which is not only convenient for management and storage, but also can improve space utilization. Frozen objects of different sizes can be classified and arranged by the rotation of the first drive shaft 603, which is convenient for subsequent transportation and distribution. The automatic unloading and arrangement functions can reduce the occurrence of human errors and improve the accuracy and reliability of logistics. At the same time, the precise control of the first servo motor 601 can ensure the frozen objects The conveying speed and position of the products are accurate. When the frozen products need to be placed in the storage box 1, confirm that the door panel 11 is in a closed state and fits tightly with the storage box 1. The external structural dimensions of one side of the door panel 11 are consistent with the internal external structural dimensions of the storage box 1, ensuring good sealing. The side where the door panel 11 fits the storage box 1 is embedded with a magnetic sheet. The magnetic effect is used to make the door panel 11 firmly adsorbed on the storage box 1, further enhancing the sealing effect and preventing the outside hot air from entering the storage box 1 and affecting the quality of the frozen products. If you need to take out a frozen product temporarily, you can quickly take out the frozen product by opening the door panel 11. If it involves the conveying or position adjustment of the products, The control panel 9 can control the operation of the first servo motor 601, the third servo motor 8 and other motors to drive the corresponding transmission mechanism or adjust the position of the components. At the same time, the first displacement sensor 401 and the second displacement sensor 506 monitor the position of the relevant components in real time and feed back the position data to the control panel 9 so that the control panel 9 can perform precise control. When it is necessary to adjust the temperature in the frozen storage box 1, the temperature controller 13 transmits the temperature information to the control panel 9. The control panel 9 controls the refrigeration intensity of the semiconductor flat refrigeration plate 10 according to the temperature conditions, or adjusts the position of the refrigeration components by controlling the relevant cylinder movements, etc., to maintain a suitable low-temperature environment in the frozen storage box 1.
