Description

Technical Field

[0001] This invention relates to the field of frozen food transfer devices, specifically a frozen food transfer device. Background Technology

[0002] Frozen agricultural products are an important component of frozen foods, including frozen vegetables, meats, and fruits. They are quickly frozen to lock in freshness, retain their original nutrients and flavors, are convenient for storage and transportation, extend shelf life, require no washing or cutting, and are easy to cook, meeting the needs of a fast-paced lifestyle. They are a high-quality alternative to fresh agricultural products.

[0003] Frozen food transfer equipment is a key piece of equipment in cold chain logistics. It is designed specifically for frozen agricultural products and other frozen foods, and has a low-temperature resistant structure that can operate stably in low-temperature environments. As a key node connecting warehousing, transportation and distribution, the transfer link is crucial to maintaining the continuity and integrity of the cold chain.

[0004] The prior art, disclosed in CN219790197U, provides a frozen food transfer device, relating to the field of frozen food technology. This frozen food transfer device has a refrigeration unit fixedly mounted on the surface of a base plate. A housing is fixedly mounted on the side of the refrigeration unit, and a door is hinged to the side surface of the housing. The door hinge is a pipe-shaped hinge. Sliding grooves are formed on both sides of the interior of the housing, and the grooves are hook-shaped. A slider is slidably connected to the surface of the groove, and a partition is fixedly mounted on the other end of the slider. When workers need to place frozen food, they open the housing door and place the food inside. Workers can adjust the internal space of the housing by pulling the partition according to the size of the food, preventing small food items from being crushed and allowing larger food items to be placed, thus increasing operational convenience.

[0005] The aforementioned existing technology can achieve the transfer of frozen food by pulling a trolley, but the trolley is slow and inefficient. In addition, manual labor or forklifts are required to complete the loading and unloading during the transfer process. When manual handling or forklifts are used in conjunction with trolley transfer, the goods are transferred many times. Each time frozen food undergoes a transfer, the time it is exposed to the external environment will be extended, thereby increasing the risk of thawing or spoilage.

[0006] It is evident that a frozen food transfer device is needed to address the problems mentioned in the background technology, such as slow transportation speed, low efficiency, the need for manual or forklift loading and unloading, and the long exposure time and easy thawing and spoilage of frozen foods due to multiple transfers.

This process does not require manual handling or the use of other forklift equipment, reducing the number of transfers of the equipment. It can directly move the goods from one compartment to another in the frozen environment, greatly improving the transfer efficiency and reducing the possibility of the goods thawing or spoiling.

[0017] Secondly, the present invention, through the setting of intermittent components and alternating lifting components, realizes that a single motor can drive the receiving belt group and the unloading belt group to alternately rise and fall. When one belt conveyor descends, the other rises. This action meets the transportation needs of transporting goods from top to bottom and stacking goods from bottom to top between two carriages. At the same time, the setting of intermittent components makes the rising and falling of the receiving belt group and the unloading belt group have time intervals, which meets the pause requirements during the receiving and unloading process. The cooperation between the intermittent components and the alternating lifting components makes the device more orderly and the process smoother when transporting goods. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-6A frozen food transfer device includes a base 1. A receiving belt assembly 2 and a discharging belt assembly 3 are hinged to both sides of the top of the base 1. A clamping assembly 4 for clamping and feeding is installed at one end of the receiving belt assembly 2. A transfer and feeding pushing assembly 5 is provided between the receiving belt assembly 2 and the discharging belt assembly 3. The clamping assembly 4 includes a fixed gear 406 and a movable gear 408 with adjustable spacing. The bottom end of the fixed gear 406 is connected to a first clamping member 409, and the bottom end of the movable gear 408 is connected to the first clamping member 409. The second clamping member 410 has the same structure as the first clamping member 409. The first clamping member 409 includes a through shaft 4091 connected to the fixed gear 406. An eccentric shaft 4092 is sleeved on the outer side below the through shaft 4091. A first hinge rod 4093 is provided below the eccentric shaft 4092. A clamping piece 4094 is hinged to the lower end of the first hinge rod 4093. A second hinge rod 4095 is hinged to the lower part of the clamping piece 4094. The first clamping member 409 and the second clamping member 410 make circular movements on both sides of the goods.

[0022] In this embodiment, a controller is installed in the device, which is electrically connected to the electronic components in the device for convenient direct control. Both the receiving belt assembly 2 and the discharging belt assembly 3 adopt a belt conveyor structure and are mounted on the base 1 via a support plate 103. The receiving belt assembly 2 and the discharging belt assembly 3 can use a lightweight metal frame structure, thus reducing the load on the base 1 during lifting or movement. The receiving belt assembly 2 is used to collect and transport the frozen food goods stacked in the lower freight car, while the discharging belt assembly 3 is used to transport the goods to the upper freight car and stack them directly in the car. The entire transport line significantly reduces the manpower and equipment required for transfer, and also shortens the transfer time. The transfer takes place between two refrigerated compartments, thus effectively avoiding the risk of goods thawing. The overall efficiency of the device is greatly improved. In this device, the receiving belt group 2 and the discharging belt group 3 have the same structure. However, a clamping component 4 for feeding is installed at one end of the receiving belt group 2, while a guard plate can be installed at one end of the discharging belt group 3 to extend the length of the side plate of the discharging belt group 3 to escort the goods out of the conveyor and stack them flat. Alternatively, a pushing mechanism can be installed at one end of the discharging belt group 3 to assist in the unloading. The pushing mechanism can adopt the same structure as the pushing component 5, or it can adopt the same clamping and feeding mechanism as the first clamping component 409 and the second clamping component 410. The specific choice can be made according to the on-site construction requirements.

[0023] Specifically, the base 1 includes a column 101, and a movable seat 102 is installed at the bottom of the column 101. Support plates 103 are provided on both sides of the column 101. The two sets of support plates 103 are respectively hinged at the middle position of the receiving belt group 2 and the discharging belt group 3. A connecting plate 104 is connected to the top of the column 101, and a conveying roller 105 is provided inside the connecting plate 104. The conveying roller 105 is located between the receiving belt group 2 and the discharging belt group 3, and the pushing component 5 is installed on one side of the conveying roller 105.

[0024] In this embodiment, the device is used during the transfer of frozen food, such as when two refrigerated trucks dock. The device can be moved between the two trucks. The receiving belt assembly 2 is located on the side of the lower truck, and the discharging belt assembly 3 is located on the side of the upper truck. The movable seat 102 is used to move the device, for example, when loading or unloading goods. The movable seat 102 moves the device, allowing the loading and unloading operation to proceed from one side of the truck to the other until all goods in the truck are transferred. The movable seat 102 integrates a roller assembly, a translation drive system, and a steering mechanism, facilitating a wider range of movement for the device. In this device, the internal cavity of the column 101 is hollow to accommodate the alternating lifting assembly 7 and the intermittent assembly 6. The alternating lifting assembly 7 is used for Z-axis positioning, and the intermittent assembly 6 is used to control the operating cycle. The column 101 is made of a metal material with high compressive strength, as it bears most of the weight of the device. Using metal helps prevent deformation and extends the device's service life. Support plate 1... 03 is used to connect the column 101 and the receiving belt assembly 2 and the discharging belt assembly 3. The support plate 103 also needs to be made of metal. Both the receiving belt assembly 2 and the discharging belt assembly 3 are equipped with rotating seats for connecting to the support plate 103. The support plate 103 is located on the left and right sides of the receiving belt assembly 2 and the discharging belt assembly 3, ensuring that the receiving belt assembly 2 and the discharging belt assembly 3 maintain a certain balance when rotating around the rotating seats. A mounting plate 701 is provided between the two support plates 103. The connecting plate 104 is located at the top of the column 101 and is set at the ends of the receiving belt group 2 and the discharging belt group 3. The equidistantly arranged conveyor rollers 105 form a transition conveying surface and are rotatably set between the two connecting plates 104. The receiving belt group 2, the discharging belt group 3 and the connecting plate 104, the connecting plate 104, the conveyor rollers 105 and the belt group adopt a non-contact independent structure. When the receiving belt group 2 and the discharging belt group 3 rotate, the presence of the connecting plate 104 and the conveyor rollers 105 will not affect them.

[0025] Specifically, the clamping assembly 4 includes a clamping motor 401, and the output end of the clamping motor 401 is provided with a first hinge plate 402. One end of the first hinge plate 402 is hinged to a second hinge plate 403. The first hinge plate 402 is coaxial with the first transmission gear 405. The moving gear 408 is provided with a through shaft inside, and the through shaft passes through one end of the second hinge plate 403 and extends to its outer side. One end of the through shaft is connected to a moving block, and the moving block is passed through by a lead screw 404. The moving block moves in the limiting plate.

[0026] In this embodiment, the second hinge plate 403 can rotate at one end of the first hinge plate 402. The first hinge plate 402 is fixed at one end coaxial with the first transmission gear 405. The first transmission gear 405 and the fixed gear 406 are also immovable. When the second hinge plate 403 is rotated, the moving gear 408 will move, and the second clamping member 410 below will move. This allows adjustment of the distance between the first clamping member 409 and the second clamping member 410, facilitating the clamping and transportation of goods of different widths. Since the first transmission gear 405 drives the fixed gear 406 and the second transmission gear 407 to rotate, and the second transmission gear 407 drives the moving gear 408 to rotate, even when adjusting the distance, the transmission will not be interrupted. The first clamping member 409 and the second clamping member 410 can perform circular motion to transport goods while adjusting the distance. One end of the lead screw 404 is connected to a handwheel. Rotating the handwheel will drive the lead screw 404 to rotate. The moving block is internally equipped with... The lead screw 404 has a matching threaded groove, so when the lead screw 404 rotates, it drives the moving block to move, which in turn drives the moving gear 408 and the second clamping member 410 to move together through the through shaft. When it is necessary to adjust the distance between the first clamping member 409 and the second clamping member 410, the lead screw 404 can be rotated by handwheel. The rotation of the lead screw 404 drives the moving block to move, which in turn drives the moving gear 408 and the second clamping member 410 to move, thus increasing the distance between the first clamping member 409 and the second clamping member 410. During the transmission process, the first transmission gear 405 will continuously drive the fixed gear 406 and the second transmission gear 407 to rotate, while the second transmission gear 407 will continue to drive the moving gear 408 to rotate. The moving gear 408 and the second transmission gear 407 always maintain a constant center distance. The displacement of the moving gear 408 is also on one side of the second transmission gear 407. During this process, the second hinge plate 403 rotates on one side of the first hinge plate 402 to provide support for the displacement of the moving gear 408.

[0027] Specifically, the first clamping member 409 and the second clamping member 410 are symmetrically arranged, and the through shaft 4091 passes through the eccentric shaft 4092, the first hinge rod 4093 and the second hinge rod 4095. The first hinge rod 4093 and the second hinge rod 4095 are arranged parallel to each other on the clamping piece 4094.

[0028] In this embodiment, an installation frame is provided at the end of the material receiving belt group 2. The installation frame is in a "冂" shape. The clamping motor 401 to the first clamping member 409 are all installed at the top of the installation frame. The first clamping member 409 and the second clamping member 410 are arranged at the bottom of the installation frame. A slot for the movement of the moving gear 408 is formed in the installation frame. In the first clamping member 409 and the second clamping member 410, the goods are clamped by the clamping piece 4094 and then transported onto the material receiving belt group 2. Therefore, the side of the clamping piece 4094 contacting the goods can be made of a material with high friction and anti-slip properties, such as rubber. The first hinge rod 4093 and the second hinge rod 4095 are symmetrically and parallelly arranged on the upper and lower sides of both ends of the clamping piece 4094. Both ends of the clamping piece 4094 form a four-bar linkage with the upper and lower hinge rods respectively. Fixed blocks are provided at the ends of the two through shafts 4091 for supporting the entire first clamping member 409. The fixed blocks can be connected to the installation frame. The first clamping member 409 and the second clamping member 410 move in a circular motion symmetrically and rotate with the through shaft 4091. The eccentric shaft 4092 pushes the hinge rod to cause the clamping piece 4094 to generate a radial displacement to achieve clamping. As the clamping piece 4094 continues to move, the clamped goods can be driven to move, so that they are moved onto the material receiving belt group 2, forming a continuous clamping and conveying trajectory, thereby assisting the goods to move onto the material receiving belt group 2.

[0029] Specifically, the material pushing component 5 includes a material pushing motor 501, and the output end of the material pushing motor 501 is connected to a first hinge short shaft 502. One end of the first hinge short shaft 502 is hinged to a hinge long shaft 503, and a second hinge short shaft 504 is hinged at the middle position of the hinge long shaft 503. One end of the hinge long shaft 503 is connected to a push plate 505.

[0030] In this embodiment, the pusher motor 501 is mounted on one side of the connecting plate 104, and a connecting plate can be installed at its bottom to support the pusher motor 501. The hinged long shaft 503 includes a first bend, a second bend, and a third bend, which are integrally formed. One end of the first bend is hinged to the first hinged short shaft 502, the connection between the first and second bends is hinged to the second hinged short shaft 504, and the third bend is connected to the push plate 505. When the pusher motor 501 is started, the push plate 505 can be pushed by the hinge shaft, and the pushing action is not linear. Instead of a straight push, the material moves horizontally, then rises at an upward angle, and then falls back down, forming a triangular trajectory. This is because during the transport process, when the receiving belt group 2 is lower and the discharging belt group 3 is higher, the horizontal pushing action may cause the goods to get stuck at the junction of the transport roller 105 and the discharging belt group 3, and the horizontal pushing action will also be restricted. However, if it is the movement trajectory of the pushing component 5, it will not cause the problems of getting stuck or restricting the action. On the contrary, when the receiving belt group 2 is lower and the discharging belt group 3 is higher, the pushing action of the pushing component 5 will help the goods move to the higher discharging belt group 3.

[0031] Please see Figures 7-11 A frozen food transfer device includes an alternating lifting assembly 7 inside a base 1, which drives a receiving belt assembly 2 and a discharging belt assembly 3 to rise and fall alternately. An intermittent assembly 6 is positioned above the alternating lifting assembly 7 to periodically drive its operation. The alternating lifting assembly 7 includes a central gear 702, with a first crankshaft 703 and a second crankshaft 706 respectively positioned on either side of the central gear 702. A first hinge 704 is positioned on one side of the first crankshaft 703, and a second hinge 706 is positioned on one side of the first hinge 704. 705. A third hinge 707 with the same structure as the first hinge 704 is provided on one side of the second crankshaft 706, and a fourth hinge 708 with the same structure as the second hinge 705 is provided on one side of the third hinge 707. The first hinge 704, the second hinge 705, the third hinge 707, and the fourth hinge 708 alternately rise and fall, and the first hinge 704 and the second hinge 705 are located at the bottom end of the receiving belt group 2, and the third hinge 707 and the fourth hinge 708 are located at the bottom end of the discharging belt group 3.

[0032] In this embodiment, the power for the alternating lifting component 7 to lift alternately comes from the drive motor 601. The drive motor 601 controls the central gear 702 to rotate intermittently through the intermittent component 6. Since the receiving belt group 2 and the discharging belt group 3 need to gradually adjust their height according to the height of the goods during the receiving and discharging process, the adjustment interval matches the goods placement cycle. The intermittent component 6 drives the central gear 702 to rotate intermittently, which can meet the intermittent pause of the operation of the receiving belt group 2 and the discharging belt group 3.

[0033] Specifically, the alternating lifting assembly 7 includes a mounting plate 701, a central gear 702 located at the middle position above the mounting plate 701, and a horizontal shaft is provided inside the central gear 702. The two ends of the horizontal shaft are respectively connected to a first crankshaft 703 and a second crankshaft 706. One end of the first crankshaft 703 and the second crankshaft 706 are respectively connected to a cam shaft, and the cam shaft is located inside the connecting groove 7043. The first crankshaft 703 and the second crankshaft 706 face opposite directions.

[0034] In this embodiment, a connecting seat is provided on the outer side of the horizontal shaft. The horizontal shaft passes through the connecting seat via a bearing. The connecting seat is installed on the top of the mounting plate 701. The first crankshaft 703 and the second crankshaft 706 have the same structure, but the orientation of their cam shafts is different. Therefore, when the central gear 702 drives the first crankshaft 703 and the second crankshaft 706 to rotate via the horizontal shaft, the first crankshaft 703 and the second crankshaft 706 will rotate in different directions. For example, when the cam shaft of the first crankshaft 703 is facing the three o'clock position and the cam shaft of the second crankshaft 706 is facing the nine o'clock position, the first crankshaft 703 will rotate from the three o'clock position to the six o'clock position. This is called rotation. When the crankshaft 706 rotates downwards, it rotates from the nine o'clock position to the twelve o'clock position, which is called upward rotation. This causes the first hinge 704 and the third hinge 707 to move differently. When the first hinge 704 extends and raises one end of the take-up belt assembly 2, the third hinge 707 retracts and lowers one end of the discharge belt assembly 3. At this time, the position of the take-up end of the take-up belt assembly 2 is lowered, and the position of the discharge end of the discharge belt assembly 3 is raised. The movements of the second hinge 705 and the fourth hinge 708 follow the first hinge 704 and the third hinge 707 respectively, assisting the take-up belt assembly 2 and the discharge belt assembly 3 in balanced raising and lowering.

[0035] Specifically, the first hinge 704 includes a first connecting shaft 7041, one end of which is connected to a bottom hinge block 7042, one side of which is connected to a connecting groove 7043, and one end of the first connecting shaft 7041 away from the bottom hinge block 7042 is connected to a middle hinge block 7044. One side of the middle hinge block 7044 is connected to a second connecting shaft 7045, and one end of the second connecting shaft 7045 away from the middle hinge block 7044 is connected to a top hinge block 7046. One end of the top hinge block 7046 is connected to a connecting block 7047, and the connecting block 7047 is located at the bottom of the receiving belt assembly 2.

[0036] In this embodiment, the bottom hinge block 7042 is connected to the mounting plate 701, the connecting block 7047 is connected to the bottom of the take-up belt assembly 2, the second hinge 705 has the same structure as the first hinge 704, its bottom is also connected to the mounting plate 701, and its top is connected to the bottom of the take-up belt assembly 2, the fourth hinge 708 has the same structure as the third hinge 707, its bottom is connected to the mounting plate 701, and its top is connected to the discharge belt assembly 3. The first hinge 704, the second hinge 705, the second crankshaft 706 and the third hinge 707 can all be made of metal with strong compressive strength, so that they are not easily deformed when they are extended and retracted in daily life. The second hinge 705 and the fourth hinge 708 serve as auxiliary lifting structures, and multiple sets can be set to more evenly support the bottom of the take-up belt assembly 2 or the discharge belt assembly 3.

[0037] Specifically, the intermittent component 6 includes a drive motor 601, and the output end of the drive motor 601 is connected to a cam 602. An eccentric block 603 is hinged to the eccentric part of the cam 602, and a long shaft 604 is mounted on the eccentric block 603. A limit groove 605 is opened on one side of the long shaft 604, and a tooth 606 is connected to the bottom end of the long shaft 604. A roller 607 is provided at the top of the cam 602, and a hinged connecting plate 608 is provided on one side of the roller 607. A positioning shaft 609 is provided at the middle position of the hinged connecting plate 608, and a moving plate 610 is hinged to one end of the hinged connecting plate 608. A limit block 611 is hinged to the front side of the moving plate 610, and the limit block 611 matches the limit groove 605. A locking block 612 is provided at the bottom end of the moving plate 610. The moving plate 610 is located on one side of the central gear 702, and the tooth 606 meshes with the central gear 702.

[0038] In this embodiment, the eccentric block 603 is located at the eccentric position of the cam 602. When the cam 602 rotates, it drives the long shaft 604 to reciprocate. During the reciprocating movement of the long shaft 604, the teeth 606 intermittently mesh with the central gear 702, thereby driving the central gear 702 to rotate. During the rotation of the cam 602, the roller 607 rolling above it will change height. The cam 602 is a disc cam, and its contour curve contacts the roller 607. The roller 607 drives one end of the hinge plate 608 to undulate, and the other end of the hinge plate 608 will also undulate. The hinge plate 608 drives the moving plate 610 to move up and down, and through the limiting block 611, it drives the long shaft 604 to move height. Therefore, the teeth 606 will intermittently contact the central gear 702, driving the central gear 702 to rotate intermittently. When the teeth 606 are in contact with the central gear 702, the locking block 612 moves away. When the teeth 606 are not in contact with the central gear 702, the locking block 612 moves away. When wheel 702 contacts, locking block 612 is engaged in the tooth gap of central gear 702, preventing central gear 702 from continuing to rotate and thus locking central gear 702. A limit block is provided on the rear side of moving plate 610. A limit groove matching the limit block can be opened on the side of the connecting seat near moving plate 610 to assist moving plate 610 up and down. A waist hole is opened in moving plate 610 to facilitate the passage of the horizontal shaft in central gear 702. A fixing block is provided on the rear side of positioning shaft 609. The fixing block is fixedly set inside column 101. Hinged connecting plate 608 rotates around positioning shaft 609. The top of limit block 611 is connected to a rotating shaft, which is located on one side of moving plate 610. Drive motor 601 is installed inside column 101. Since the front and rear connecting seats support central gear 702 through horizontal shaft, there is a distance between central gear 702 and mounting plate 701. This distance satisfies the movement space of locking block 612.

[0039] During use, an external power supply is required to provide power to the device for normal operation. The device can be moved between two refrigerated compartments. The clamping assembly 4 at one end of the receiving belt assembly 2 is aligned with the frozen food to be unloaded. The clamping motor 401 is started, causing it to drive the first transmission gear 405 to rotate. The first transmission gear 405 drives the fixed gear 406 and the second transmission gear 407 to rotate. The second transmission gear 407 drives the moving gear 408 to rotate. The fixed gear 406 and the moving gear 408 rotate synchronously, respectively driving the first clamping member 409 and the second clamping member 410 to operate. The through shaft 4091 in the first clamping member 409 rotates, driving the eccentric shaft 4092 and the first hinge rod 409. 3. When the second hinge rod 4095 rotates, the clamping piece 4094 between the first hinge rod 4093 and the second hinge rod 4095 will move in a circular motion. In conjunction with the clamping piece in the second clamping piece 410, the goods can be clamped and transported, so that they move on the activated receiving belt group 2. After the goods are transported by the receiving belt group 2, they reach the transport roller 105. The pusher motor 501 is activated. The pusher motor 501 drives the first hinge short shaft 502 to rotate. The first hinge short shaft 502 drives the hinge long shaft 503 to rotate. In conjunction with the positioning of the second hinge short shaft 504, the pusher plate 505 repeatedly pushes the goods located on the transport roller 105 to the unloading belt group 3. The goods continue to be transported by the unloading belt group 3 until the goods are stacked in the transfer car. When transporting goods, the drive motor 601, which is activated, drives the cam 602 to rotate. The cam 602 drives the eccentric block 603 to rotate, which in turn drives the long shaft 604 to reciprocate. The gear 606 follows the reciprocating movement of the long shaft 604, which in turn drives the central gear 702 meshing with it to rotate. When the cam 602 rotates, the roller 607 rolls on the top of the cam 602. Due to the height difference at the edge of the cam 602, the roller 607 also moves up and down. The roller 607 drives the hinge plate 608 to rotate around the positioning shaft 609 as the center point. When a yaw action occurs, the hinged connecting plate 608 drives the moving plate 610 to rise and fall. Simultaneously, the moving plate 610 drives the limiting block 611 to rise and fall together. During this movement, the limiting block 611, through the limiting groove 605, drives the entire long shaft 604 to rise and fall, causing the long shaft 604 to rise and fall during its reciprocating motion. Only when the long shaft 604 descends will it engage with the central gear 702, causing it to rotate once. When the long shaft 604 rises, the locking block 612 rises into the gap of the central gear 702, locking it in place. Gear 702 rotates intermittently. When the central gear 702 rotates, it drives the first crankshaft 703 and the second crankshaft 706 to rotate respectively. However, the rotation directions of the first crankshaft 703 and the second crankshaft 706 are different. When the first crankshaft 703 rotates, it drives the entire first hinge 704 to unfold through the connecting groove 7043. The second hinge 705 also unfolds on one side. The unfolded first hinge 704 and second hinge 705 will lift one end of the take-up belt assembly 2, so that the take-up belt assembly 2 is centered on the hinge point with the support plate 103. As rotation occurs, one end of the clamping assembly 4 gradually descends, while the third hinge 707 and the fourth hinge 708 retract, causing one end of the unloading belt assembly 3 to descend, and the other end of the unloading belt assembly 3 to rise. The descending position of the clamping assembly 4 satisfies the state of disassembling the stacked frozen food turnover boxes one by one from top to bottom, while the gradually rising end of the unloading belt assembly 3 satisfies the state of stacking from bottom to top. With the movement of the moving seat 102, the food stacked in one set of frozen compartments can be transported in an orderly manner to another set of empty compartments for stacking, thus completing the transfer work.
