[0002] As people's demands for food quality and taste increase, quick-freezing machines, as a highly efficient freezing equipment, are being used more and more widely. Quick-freezing machines can not only rapidly lower the temperature of food, causing its internal moisture to quickly freeze into ice crystals, thus preserving the original flavor, texture, and nutritional value, but also have advantages such as high automation, high production efficiency, and ease of operation. Quick-freezing machines typically place food on a conveyor belt for freezing; however, during the quick-freezing process, the conveyor belt's mesh can easily stick to the food, making unloading difficult. At the same time, uneven cooling can also occur, leading to poor freezing results. Summary of the Invention

[0067] The invention will now be further described with reference to the accompanying drawings.

[0068] Quick-freezing machines not only rapidly lower the temperature of food, causing its internal moisture to quickly condense into ice crystals, thus preserving the original flavor, texture, and nutritional value, but also offer advantages such as high automation, high production efficiency, and ease of operation. Quick-freezing machines typically place frozen goods on a conveyor belt. Part of the cold air is directed directly and rapidly from above the conveyor belt onto the upper surface of the frozen goods, while another part is directed from below the conveyor belt onto the lower surface, achieving rapid freezing. However, during the quick-freezing process, due to the high moisture and oil content of the frozen goods and the rapid temperature changes, the conveyor belt can easily stick to the food, making unloading difficult. Furthermore, uneven cooling can also occur, resulting in poor freezing performance.

[0069] Example 1

[0070] like Figure 1 As shown, this embodiment of the invention provides a quick-freezing machine transport structure, which includes a freezing chamber 10, a drive device 20, and a storage device 30. The freezing chamber 10 is provided with a freezing channel 110. The drive device 20 is disposed on the freezing chamber 10. The storage device 30 is used to place items to be frozen. The storage device 30 is disposed on the drive device 20 and engages with the drive device 20 for transmission, so as to convert the movement of the drive device 20 into the rotation of the storage device 30 and the movement along the length direction of the freezing channel 110, thereby freezing the items to be frozen.

[0071] As can be seen from the above, by setting the drive device 20 to drive the storage device 30 to rotate, the items to be frozen are continuously tumbled inside the storage device. This not only prevents the items from sticking to the storage device 30 during the quick-freezing process, but also prevents the items from sticking together, ensuring rapid unloading. This solves the problem of existing conveyor belts easily sticking to food, leading to difficulties in unloading. Simultaneously, the drive device 20 driving the storage device 30 to rotate, causing the items to be frozen to continuously tumble inside the storage device, ensures more uniform cooling and quick-freezing during the process. This not only improves the quick-freezing speed and shortens the freezing cycle, but also ensures the freezing effect, thus solving the problem of uneven cooling and poor freezing effect that occurs with existing frozen products on conveyor belts. Furthermore, the drive device 20 can also move the storage device 30 along the length of the freezing channel 110, realizing automatic transport of the storage device 30. This provides a structural basis for the automatic feeding and unloading of items to be frozen, improving the degree of automation and saving manpower and resources.

[0072] It should be noted that the outer layer of the freezer chamber 10 is provided with an insulation layer. When the quick-freezing machine transport structure is applied to the quick-freezing machine, multiple upper and lower air inlets are installed in the freezing channel 110. The upper air inlet is located above the storage device 30, and the lower air inlet is located below the storage device 30. Cold air is blown into the items to be frozen in the storage device through the upper and lower air inlets, so that the items to be frozen are frozen quickly.

[0073] It should also be noted that, such as Figure 1 As shown, the length direction of the freezing channel 110 is parallel to the X direction.

[0074] It should also be noted that the items to be frozen are food products, such as poultry, meat, seafood, pasta, meatballs, prepared foods, vegetables, and packaged ready-made dishes.

[0075] Example 2

[0076] like Figure 1 As shown, this embodiment of the invention provides a quick-freezing machine transport structure, including a freezing chamber 10, a drive device 20, and a storage device 30; the freezing chamber 10 is provided with a freezing channel 110; the drive device 20 is disposed on the freezing chamber 10; the storage device 30 is used to place items to be frozen, and the storage device 30 is disposed on the drive device 20 and engages with the drive device 20 for transmission, so as to convert the movement of the drive device 20 into the rotation of the storage device 30 and the movement along the length direction of the freezing channel 110, thereby freezing the items to be frozen.

[0077] By setting up a drive device 20 to rotate the storage device 30, the items to be frozen continuously tumble within the storage device 30. This not only prevents the items from sticking to the storage device 30 during the quick-freezing process but also prevents the items from sticking together, ensuring rapid unloading. This solves the problem of existing conveyor belts' mesh belts easily sticking to food, leading to difficult unloading. Simultaneously, the drive device 20's rotation of the storage device 30, causing the items to tumble continuously within it, ensures more uniform cooling during the quick-freezing process. This not only increases the freezing speed and shortens the freezing cycle but also guarantees the freezing effect, thus solving the problem of uneven cooling and poor freezing effect that often occurs with frozen products on conveyor belts. Furthermore, the drive device 20 can also move the storage device 30 along the length of the freezing channel 110, enabling automatic transport of the storage device 30. This provides a structural basis for the automatic feeding and unloading of items to be frozen, improving the degree of automation and saving manpower and resources.

[0078] It should be noted that the outer layer of the freezer chamber 10 is provided with an insulation layer. When the quick-freezing machine transport structure is applied to the quick-freezing machine, multiple upper and lower air inlets are installed in the freezing channel 110. The upper air inlets are located above the storage device 30, and the lower air inlets are located below the storage device 30. Cold air is blown into the items to be frozen in the storage device 30 through the upper and lower air inlets, so that the items to be frozen are frozen quickly.

[0079] It should also be noted that, such as Figure 1 As shown, the length direction of the freezing channel 110 is parallel to the X direction.

[0080] It should also be noted that the items to be frozen are food products, such as poultry, meat, seafood, pasta, meatballs, prepared foods, vegetables, and packaged ready-made dishes.

[0081] like Figure 2 As shown, in some embodiments, the two ends of the freezing channel 110 are respectively provided with a feed inlet 1101 and a discharge outlet 1102, and the driving device 20 is configured to drive the storage device 30 to rotate and move from the feed inlet 1101 to the discharge outlet 1102.

[0082] By setting up a drive device 20 to move the storage device 30 from the inlet 1101 to the outlet 1102, the automatic transportation of the storage device 30 is realized, providing a structural basis for the automatic feeding and discharging of items to be frozen and improving the degree of automation.

[0083] like Figures 2-4As shown, in some embodiments, the driving device 20 includes a driving rod 210, a driving assembly 220, a feeding guide rail 230, and a driving motor; the driving rod 210 is rotatably disposed within the freezing channel 110; the driving assembly 220 is disposed opposite to each other in the width direction of the freezing channel 110, and the driving assembly 220 is connected to both ends of the driving rod 210 respectively, and the storage device 30 is engaged with the driving assembly 220 for transmission; the feeding guide rail 230 is disposed opposite to each other in the width direction of the freezing channel 110, and the feeding guide rail 230 extends along the length direction of the freezing channel 110, and the storage device 30 is disposed on the feeding guide rail 230; the driving motor is disposed on the freezing chamber 10, and the driving motor is connected to the driving rod 210, and the driving motor can drive the driving rod 210 to rotate, so as to drive the driving assembly 220 to move.

[0084] The drive rod 210, drive assembly 220, feed guide rail 230 and drive motor provide a structural basis for the rotation and movement of the storage device 30. The feed guide rail 230 supports and guides the storage device 30. The drive motor provides power and drives the drive rod 210 to rotate. The drive rod 210 drives the drive assembly 220 to move, thereby the drive assembly 220 drives the storage device 30 to rotate and move along the feed guide rail 230.

[0085] It should be noted that both ends of the drive rod 210 are rotatably mounted in the freezing channel 110 via rolling bearings, among other things.

[0086] It should also be noted that, such as Figure 1 As shown, the width direction of the freezing channel 110 is parallel to the Y direction.

[0087] It should also be noted that the drive motor shaft can be connected to the drive rod 210 via a coupling.

[0088] like Figure 2 As shown, in some embodiments, the drive assembly 220 includes a plurality of drive sprockets 2201 and a drive chain 2202; the plurality of drive sprockets 2201 are arranged at intervals along the length direction of the freezing channel 110, the plurality of drive sprockets 2201 are rotatably disposed on the freezing chamber 10, and one of the drive sprockets 2201 is connected to the drive rod 210; the inner side of the drive chain 2202 meshes with the plurality of drive sprockets 2201; wherein, the storage device 30 includes a transmission sprocket 320, the transmission sprocket 320 meshing with the outer side of the drive chain 2202.

[0089] The drive chain 2202 meshes with the drive sprocket 2201 and the transmission sprocket 320 respectively, forming a sprocket and chain drive. This not only transmits a large torque, ensuring the stability and reliability of the storage device 30's movement, but also has a long service life and is easy to maintain and replace. Furthermore, the sprocket and chain drive allows space to be reserved below the storage device 30, facilitating material discharge and return, making full use of space, and resulting in a compact structure. The drive rod 210 drives the drive sprocket 2201 to rotate, which meshes with the drive chain 2202, causing the drive chain 2202 to move. The drive chain 2202 meshes with the transmission sprocket 320, causing the transmission sprocket 320 to rotate and move along the length of the freezing channel 110.

[0090] It should be noted that the number of drive sprockets 2201 is at least two, but the specific number of drive sprockets 2201 is not limited in this application. For example, as Figure 2 As shown, there are two drive sprockets 2201. The two drive sprockets 2201 are arranged at intervals along the length of the freezing channel 110. The two drive sprockets 2201 are located at the feed inlet 1101 and the discharge outlet 1102, respectively.

[0091] It should also be noted that the drive sprocket 2201 is connected to the drive rod 210 by means of a key connection, including but not limited to the method of connection.

[0092] Example 3

[0093] like Figure 1 As shown, this embodiment of the invention provides a quick-freezing machine transport structure, including a freezing chamber 10, a drive device 20, and a storage device 30; the freezing chamber 10 is provided with a freezing channel 110; the drive device 20 is disposed on the freezing chamber 10; the storage device 30 is used to place items to be frozen, and the storage device 30 is disposed on the drive device 20 and engages with the drive device 20 for transmission, so as to convert the movement of the drive device 20 into the rotation of the storage device 30 and the movement along the length direction of the freezing channel 110, thereby freezing the items to be frozen.

[0094] By setting up a drive device 20 to rotate the storage device 30, the items to be frozen continuously tumble within the storage device 30. This not only prevents the items from sticking to the storage device 30 during the quick-freezing process but also prevents the items from sticking together, ensuring rapid unloading. This solves the problem of existing conveyor belts' mesh belts easily sticking to food, leading to difficult unloading. Simultaneously, the drive device 20's rotation of the storage device 30, causing the items to tumble continuously within it, ensures more uniform cooling during the quick-freezing process. This not only increases the freezing speed and shortens the freezing cycle but also guarantees the freezing effect, thus solving the problem of uneven cooling and poor freezing effect that often occurs with frozen products on conveyor belts.

This provides a structural basis for the automatic feeding and unloading of items to be frozen, improving the degree of automation and saving manpower and resources.

[0095] It should be noted that the outer layer of the freezer chamber 10 is provided with an insulation layer. When the quick-freezing machine transport structure is applied to the quick-freezing machine, multiple upper and lower air inlets are installed in the freezing channel 110. The upper air inlets are located above the storage device 30, and the lower air inlets are located below the storage device 30. Cold air is blown into the items to be frozen in the storage device 30 through the upper and lower air inlets, so that the items to be frozen are frozen quickly.

[0096] It should also be noted that, such as Figure 1 As shown, the length direction of the freezing channel 110 is parallel to the X direction.

[0097] It should also be noted that the items to be frozen are food products, such as poultry, meat, seafood, pasta, meatballs, prepared foods, vegetables, and packaged ready-made dishes.

[0098] like Figure 2 As shown, in some embodiments, the two ends of the freezing channel 110 are respectively provided with a feed inlet 1101 and a discharge outlet 1102, and the driving device 20 is configured to drive the storage device 30 to rotate and move from the feed inlet 1101 to the discharge outlet 1102.

[0099] By setting up a drive device 20 to move the storage device 30 from the inlet 1101 to the outlet 1102, the automatic transportation of the storage device 30 is realized, providing a structural basis for the automatic feeding and discharging of items to be frozen and improving the degree of automation.

[0100] like Figures 2-4As shown, in some embodiments, the driving device 20 includes a driving rod 210, a driving assembly 220, a feeding guide rail 230, and a driving motor; the driving rod 210 is rotatably disposed within the freezing channel 110; the driving assembly 220 is disposed opposite to each other in the width direction of the freezing channel 110, and the driving assembly 220 is connected to both ends of the driving rod 210 respectively, and the storage device 30 is engaged with the driving assembly 220 for transmission; the feeding guide rail 230 is disposed opposite to each other in the width direction of the freezing channel 110, and the feeding guide rail 230 extends along the length direction of the freezing channel 110, and the storage device 30 is disposed on the feeding guide rail 230; the driving motor is disposed on the freezing chamber 10, and the driving motor is connected to the driving rod 210, and the driving motor can drive the driving rod 210 to rotate, so as to drive the driving assembly 220 to move.

[0101] The drive rod 210, drive assembly 220, feed guide rail 230 and drive motor provide a structural basis for the rotation and movement of the storage device 30. The feed guide rail 230 supports and guides the storage device 30. The drive motor provides power and drives the drive rod 210 to rotate. The drive rod 210 drives the drive assembly 220 to move, thereby the drive assembly 220 drives the storage device 30 to rotate and move along the feed guide rail 230.

[0102] It should be noted that both ends of the drive rod 210 are rotatably mounted in the freezing channel 110 via rolling bearings, among other things.

[0103] It should also be noted that, such as Figure 1 As shown, the width direction of the freezing channel 110 is parallel to the Y direction.

[0104] It should also be noted that the drive motor shaft can be connected to the drive rod 210 via a coupling.

[0105] like Figure 2 As shown, in some embodiments, the drive assembly 220 includes a plurality of drive sprockets 2201 and a drive chain 2202; the plurality of drive sprockets 2201 are arranged at intervals along the length direction of the freezing channel 110, the plurality of drive sprockets 2201 are rotatably disposed on the freezing chamber 10, and one of the drive sprockets 2201 is connected to the drive rod 210; the inner side of the drive chain 2202 meshes with the plurality of drive sprockets 2201; wherein, the storage device 30 includes a transmission sprocket 320, the transmission sprocket 320 meshing with the outer side of the drive chain 2202.

[0106] The drive chain 2202 meshes with the drive sprocket 2201 and the transmission sprocket 320 respectively, forming a sprocket and chain drive. This not only transmits a large torque, ensuring the stability and reliability of the storage device 30's movement, but also has a long service life and is easy to maintain and replace. Furthermore, the sprocket and chain drive allows space to be reserved below the storage device 30, facilitating material discharge and return, making full use of space, and resulting in a compact structure. The drive rod 210 drives the drive sprocket 2201 to rotate, which meshes with the drive chain 2202, causing the drive chain 2202 to move. The drive chain 2202 meshes with the transmission sprocket 320, causing the transmission sprocket 320 to rotate and move along the length of the freezing channel 110.

[0107] It should be noted that the number of drive sprockets 2201 is at least two, but the specific number of drive sprockets 2201 is not limited in this application. For example, as Figure 2 As shown, there are two drive sprockets 2201. The two drive sprockets 2201 are arranged at intervals along the length of the freezing channel 110. The two drive sprockets 2201 are located at the feed inlet 1101 and the discharge outlet 1102, respectively.

[0108] It should also be noted that the drive sprocket 2201 is connected to the drive rod 210 by means of a key connection, including but not limited to the method of connection.

[0109] like Figures 1-4 As shown, in some embodiments, the storage device 30 includes a storage roller 330, which abuts against the feed guide rail 230, and transmission sprockets 320 are respectively disposed at both ends of the storage roller 330; wherein, a plurality of through holes 3302 are provided on the circumferential surface of the storage roller 330.

[0110] By setting the drive sprockets 320 at both ends of the storage drum 330, the storage drum 330 is driven to rotate and move along the feed guide rail 230, thereby causing the items to be frozen inside the storage drum 330 to tumble; by setting multiple through holes 3302, cold air can enter the storage drum 330, improving the quick-freezing effect and shortening the quick-freezing cycle.

[0111] It should be noted that the storage device 30 includes limiting plates respectively disposed at both ends of the storage roller 330. The two limiting plates are located between the two transmission sprockets 320. The two limiting plates correspond one-to-one with the two feeding guide rails 230. The limiting plates abut against the corresponding feeding guide rails 230 to limit the storage roller 330 in the width direction of the freezing channel 110, ensuring the normal operation of the storage roller 330, thereby preventing the storage roller 330 from shifting during movement and causing it to be unable to move normally.

[0112] like Figure 6As shown, in some embodiments, the storage roller 330 includes a main body 3301, a plurality of roller doors 3303, and a roller motor; the main body 3301 has a plurality of openings on its circumferential surface; the plurality of roller doors 3303 correspond one-to-one with the plurality of openings, and the roller doors 3303 are rotatably disposed on the main body 3301 to close or open the corresponding openings; the roller motors are disposed on the main body 3301, and the plurality of roller motors correspond one-to-one with the plurality of roller doors 3303, and the roller motors are connected to the corresponding roller doors 3303 to drive the roller doors 3303 to rotate.

[0113] By setting a roller motor to drive the drum door 3303 to rotate, the drum door 3303 can be opened and closed automatically, which facilitates feeding and discharging, and provides a structural basis for realizing automatic feeding and discharging.

[0114] It should be noted that the number of openings is set according to needs, for example, such as Figure 6 As shown, there are three openings.

[0115] It should also be noted that the gate 3303 is, but is not limited to, rotatably mounted on the main body 3301 via a rotating shaft; the gate 3303 is arc-shaped, and when the gate 3303 closes the corresponding openings respectively, the storage drum 330 is cylindrical; the output shaft of the drum motor is connected to the corresponding gate 3303.

[0116] Example 4

[0117] like Figure 1 As shown, this embodiment of the invention provides a quick-freezing machine transport structure, including a freezing chamber 10, a drive device 20, and a storage device 30; the freezing chamber 10 is provided with a freezing channel 110; the drive device 20 is disposed on the freezing chamber 10; the storage device 30 is used to place items to be frozen, and the storage device 30 is disposed on the drive device 20 and engages with the drive device 20 for transmission, so as to convert the movement of the drive device 20 into the rotation of the storage device 30 and the movement along the length direction of the freezing channel 110, thereby freezing the items to be frozen.

[0118] By setting the drive device 20 to drive the storage device 30 to rotate, the items to be frozen continuously tumble within the storage device 30. This not only prevents the items from sticking to the storage device 30 during the quick-freezing process, but also prevents the items from sticking together, ensuring rapid unloading. This solves the problem of existing conveyor belts easily sticking to food, leading to difficulties in unloading. Simultaneously, the drive device 20 driving the storage device 30 to rotate, causing the items to continuously tumble within the storage device 30, ensures more uniform cooling during the quick-freezing process. This not only increases the quick-freezing speed and shortens the freezing cycle, but also guarantees the freezing effect, thus solving the problem of uneven cooling and poor freezing effect that often occurs with frozen products on conveyor belts. Furthermore, the drive device 20 can also move the storage device 30 along the length of the freezing channel 110, realizing automatic transport of the storage device 30. This provides a structural basis for the automatic feeding and unloading of items to be frozen, improving the degree of automation and saving manpower and resources.

[0119] It should be noted that the outer layer of the freezer chamber 10 is provided with an insulation layer. When the quick-freezing machine transport structure is applied to the quick-freezing machine, multiple upper and lower air inlets are installed in the freezing channel 110. The upper air inlets are located above the storage device 30, and the lower air inlets are located below the storage device 30. Cold air is blown into the items to be frozen in the storage device 30 through the upper and lower air inlets, so that the items to be frozen are frozen quickly.

[0120] It should also be noted that, such as Figure 1 As shown, the length direction of the freezing channel 110 is parallel to the X direction.

[0121] It should also be noted that the items to be frozen are food products, such as poultry, meat, seafood, pasta, meatballs, prepared foods, vegetables, and packaged ready-made dishes.

[0122] like Figure 2 As shown, in some embodiments, the two ends of the freezing channel 110 are respectively provided with a feed inlet 1101 and a discharge outlet 1102, and the driving device 20 is configured to drive the storage device 30 to rotate and move from the feed inlet 1101 to the discharge outlet 1102.

[0123] By setting up a drive device 20 to move the storage device 30 from the inlet 1101 to the outlet 1102, the automatic transportation of the storage device 30 is realized, providing a structural basis for the automatic feeding and discharging of items to be frozen and improving the degree of automation.

[0124] like Figures 2-4As shown, in some embodiments, the driving device 20 includes a driving rod 210, a driving assembly 220, a feeding guide rail 230, and a driving motor; the driving rod 210 is rotatably disposed within the freezing channel 110; the driving assembly 220 is disposed opposite to each other in the width direction of the freezing channel 110, and the driving assembly 220 is connected to both ends of the driving rod 210 respectively, and the storage device 30 is engaged with the driving assembly 220 for transmission; the feeding guide rail 230 is disposed opposite to each other in the width direction of the freezing channel 110, and the feeding guide rail 230 extends along the length direction of the freezing channel 110, and the storage device 30 is disposed on the feeding guide rail 230; the driving motor is disposed on the freezing chamber 10, and the driving motor is connected to the driving rod 210, and the driving motor can drive the driving rod 210 to rotate, so as to drive the driving assembly 220 to move.

[0125] The drive rod 210, drive assembly 220, feed guide rail 230 and drive motor provide a structural basis for the rotation and movement of the storage device 30. The feed guide rail 230 supports and guides the storage device 30. The drive motor provides power and drives the drive rod 210 to rotate. The drive rod 210 drives the drive assembly 220 to move, thereby the drive assembly 220 drives the storage device 30 to rotate and move along the feed guide rail 230.

[0126] It should be noted that both ends of the drive rod 210 are rotatably mounted in the freezing channel 110 via rolling bearings, among other things.

[0127] It should also be noted that, such as Figure 1 As shown, the width direction of the freezing channel 110 is parallel to the Y direction.

[0128] It should also be noted that the drive motor shaft can be connected to the drive rod 210 via a coupling.

[0129] like Figure 2 As shown, in some embodiments, the drive assembly 220 includes a plurality of drive sprockets 2201 and a drive chain 2202; the plurality of drive sprockets 2201 are arranged at intervals along the length direction of the freezing channel 110, the plurality of drive sprockets 2201 are rotatably disposed on the freezing chamber 10, and one of the drive sprockets 2201 is connected to the drive rod 210; the inner side of the drive chain 2202 meshes with the plurality of drive sprockets 2201; wherein, the storage device 30 includes a transmission sprocket 320, the transmission sprocket 320 meshing with the outer side of the drive chain 2202.

[0130] The drive chain 2202 meshes with the drive sprocket 2201 and the transmission sprocket 320 respectively, forming a sprocket and chain drive. This not only transmits a large torque, ensuring the stability and reliability of the storage device 30's movement, but also has a long service life and is easy to maintain and replace. Furthermore, the sprocket and chain drive allows space to be reserved below the storage device 30, facilitating material discharge and return, making full use of space, and resulting in a compact structure. The drive rod 210 drives the drive sprocket 2201 to rotate, which meshes with the drive chain 2202, causing the drive chain 2202 to move. The drive chain 2202 meshes with the transmission sprocket 320, causing the transmission sprocket 320 to rotate and move along the length of the freezing channel 110.

[0131] It should be noted that the number of drive sprockets 2201 is at least two, but the specific number of drive sprockets 2201 is not limited in this application. For example, as Figure 2 As shown, there are two drive sprockets 2201. The two drive sprockets 2201 are arranged at intervals along the length of the freezing channel 110. The two drive sprockets 2201 are located at the feed inlet 1101 and the discharge outlet 1102, respectively.

[0132] It should also be noted that the drive sprocket 2201 is connected to the drive rod 210 by means of a key connection, including but not limited to the connection between the drive sprocket and the drive rod 210.

[0133] like Figures 1-4 As shown, in some embodiments, the storage device 30 includes a storage roller 330, which abuts against the feed guide rail 230, and transmission sprockets 320 are respectively disposed at both ends of the storage roller 330; wherein, a plurality of through holes 3302 are provided on the circumferential surface of the storage roller 330.

[0134] By setting the drive sprockets 320 at both ends of the storage drum 330, the storage drum 330 is driven to rotate and move along the feed guide rail 230, thereby causing the items to be frozen inside the storage drum 330 to tumble; by setting multiple through holes 3302, cold air can enter the storage drum 330, improving the quick-freezing effect and shortening the quick-freezing cycle.

[0135] It should be noted that the storage device 30 includes limiting plates respectively disposed at both ends of the storage roller 330. The two limiting plates are located between the two transmission sprockets 320. The two limiting plates correspond one-to-one with the two feeding guide rails 230. The limiting plates abut against the corresponding feeding guide rails 230 to limit the storage roller 330 in the width direction of the freezing channel 110, ensuring the normal operation of the storage roller 330, thereby preventing the storage roller 330 from shifting during movement and causing it to be unable to move normally.

[0136] like Figure 6As shown, in some embodiments, the storage roller 330 includes a main body 3301, a plurality of roller doors 3303, and a roller motor; the main body 3301 has a plurality of openings on its circumferential surface; the plurality of roller doors 3303 correspond one-to-one with the plurality of openings, and the roller doors 3303 are rotatably disposed on the main body 3301 to close or open the corresponding openings; the roller motors are disposed on the main body 3301, and the plurality of roller motors correspond one-to-one with the plurality of roller doors 3303, and the roller motors are connected to the corresponding roller doors 3303 to drive the roller doors 3303 to rotate.

[0137] By setting a roller motor to drive the drum door 3303 to rotate, the drum door 3303 can be opened and closed automatically, which facilitates feeding and discharging, and provides a structural basis for realizing automatic feeding and discharging.

[0138] It should be noted that the number of openings is set according to needs, for example, such as Figure 6 As shown, there are three openings.

[0139] It should also be noted that the gate 3303 is, but is not limited to, rotatably mounted on the main body 3301 via a rotating shaft; the gate 3303 is arc-shaped, and when the gate 3303 closes the corresponding openings respectively, the storage drum 330 is cylindrical; the output shaft of the drum motor is connected to the corresponding gate 3303.

[0140] like Figure 5 As shown, in some embodiments, the quick-freezing machine transport structure further includes a discharge device 40 and a return device 50; the discharge device 40 is located at the discharge port 1102; the return device 50 is located below the feed guide rail 230 and is configured to transfer the storage device 30 from the discharge port 1102 to the feed port 1101.

[0141] By setting up the discharge device 40 and the return device 50, a structural foundation is provided for the automatic discharge and return of the automatic storage roller 330. The automatic discharge of the items to be frozen after quick-freezing is achieved, thereby reducing manual intervention and improving the degree of automation. The return device 50 transfers the empty storage device 30 after discharge back to the feed inlet 1101, realizing the recycling of the storage device 30.

[0142] like Figure 5As shown, in some embodiments, the discharge device 40 includes a first conveying section 410, a second conveying section 420, a third conveying section 430, and a discharge trough 440; the first conveying section 410 has a first preset angle with the length direction of the freezing channel 110, and the end of the first conveying section 410 near the discharge port 1102 is higher than the end of the first conveying section 410 away from the discharge port 1102; the second conveying section 420 is disposed on the end of the first conveying section 410 away from the discharge port 1102, and the second conveying section 420 is connected to the freezing channel 110. The length direction of the channel 110 has a second preset angle, and the end of the second conveying section 420 near the discharge port 1102 is higher than the end of the second conveying section 420 away from the discharge port 1102; the third conveying section 430 is disposed between the first conveying section 410 and the second conveying section 420, and the third conveying section 430 is used to transfer the storage device 30 from the first conveying section 410 to the second conveying section 420; the discharge trough 440 is disposed below the third conveying section 430, and the discharge trough 440 is used to receive the items to be frozen in the storage device.

[0143] By setting an inclined first conveyor section 410, unpowered conveying is achieved, allowing the storage roller 330 to be conveyed from the discharge port 1102 to the third conveyor section 430 without power. The third conveyor section 430 then conveys the storage roller 330 from the first conveyor section 410 to the second conveyor section 420, where it is simultaneously discharged, transferring the quick-frozen items to the discharge trough 440. By setting an inclined second conveyor section 420, unpowered conveying is achieved, allowing the storage roller 330 to be conveyed to the return device 50 without power, thus enabling the recycling of the empty storage roller 330.

[0144] It should be noted that the first preset angle is less than 90°, and the specific value of the first preset angle can be set as needed; the second preset angle is less than 90°, and the specific value of the second preset angle can be set as needed.

[0145] It should also be noted that the first conveying unit 410 includes a first conveying guide rail disposed opposite to each other in the width direction of the freezing channel 110, and the first conveying guide rail plays a supporting and guiding role for the storage roller 330; the second conveying unit 420 includes a second conveying guide rail disposed opposite to each other in the width direction of the freezing channel 110, and the second conveying guide rail plays a supporting and guiding role for the storage roller 330.

[0146] It should also be noted that the third conveying section 430 includes a discharge guide rail arranged opposite to the freezing channel 110 in the width direction. The discharge guide rail is parallel to the length direction of the freezing channel 110 and plays a supporting and guiding role for the storage drum 330. The third conveying section 430 also includes a chain conveyor. The chain of the chain conveyor meshes with the drive sprocket 320, driving the storage drum 330 to rotate and move along the discharge guide rail, so that the storage drum 330 can move from the first conveying section 410 to the second conveying section 420. The chain conveyor is prior art, and its specific structure will not be described in detail in this application.

[0147] like Figure 5 As shown, in some embodiments, the return device 50 includes a return conveying assembly 510 and a lifting assembly 520; the return conveying assembly 510 is configured to receive the storage device 30 transferred by the discharge device 40 and convey it to the inlet 1101; the lifting assembly 520 is disposed on one end of the return conveying assembly 510 near the inlet 1101, and the lifting assembly 520 can drive the storage device 30 to move in the height direction of the freezing channel 110.

[0148] By setting up a return material conveying component 510, the storage device 30 is transported from the discharge port 1102 to the inlet port 1101, and the lifting component 520 is used to drive the storage device 30 to the drive component 220, so as to realize the recycling of the storage device 30, avoid the storage device 30 being idle, and eliminate the need for manual handling of the storage device 30, thereby improving work efficiency.

[0149] It should be noted that, as Figure 1 As shown, the height direction of the freezing channel 110 is parallel to the Z direction, and the height direction, the length direction of the freezing channel 110, and the width direction of the freezing channel 110 are perpendicular.

[0150] It should also be noted that the return material conveying assembly 510 includes, but is not limited to, belt conveyors and chain conveyors. The structures of belt conveyors and chain conveyors are existing technologies and will not be described in detail in this application.

[0151] It should also be noted that the lifting assembly 520 includes, but is not limited to, scissor lifts and screw jacks. The structures of scissor lifts and screw jacks are existing technologies and will not be described in detail in this application.

[0152] In some embodiments, the quick-freezing machine transport structure includes a feed sensor, a discharge sensor, and a controller; the feed sensor is disposed at the feed inlet 1101, and the feed sensor can sense the storage device 30 passing through the feed inlet 1101 and generate a corresponding feed sensing electrical signal; the discharge sensor is disposed above the discharge chute 440, and the discharge sensor can sense the storage device 30 passing through the discharge chute 440 and generate a corresponding discharge sensing electrical signal; the controller is electrically connected to the feed sensor and the discharge sensor respectively, and the controller can receive the feed sensing electrical signal and the discharge sensing electrical signal, and control the roller motor to work according to the feed sensing electrical signal and the discharge sensing electrical signal.

[0153] By setting up feeding sensors, discharging sensors, and a controller, the storage roller 330 can feed and discharge materials at preset positions, achieving intelligent production and improving work efficiency.

[0154] It should be noted that the feed sensor and discharge sensor include, but are not limited to, proximity switches. When the feed sensor and discharge sensor are proximity switches, the proximity switch can sense the approach of the storage roller 330. When the storage roller 330 approaches the proximity switch, the sensing distance decreases, thereby changing the state of the proximity switch and generating a corresponding sensing electrical signal. The proximity switch includes, but is not limited to, photoelectric proximity switches, magnetic proximity switches, and ultrasonic proximity switches. For example, when the proximity switch is a photoelectric proximity switch, the photoelectric proximity switch uses the degree of light blocking by the object to sense the approach of the object. It includes a transmitter and a receiver. The transmitter emits a light beam. When the storage roller 330 approaches, the light beam is blocked, and the light signal received by the receiver is weakened, thereby generating a corresponding sensing electrical signal.

[0155] It should also be noted that the gates 3303 of the storage roller 330 can be named Gate 1, Gate 2, and Gate 3 respectively; the transmission position relationship between the transmission sprocket 320 and the drive chain 2202 can be pre-calibrated, that is, when the storage roller 330 moves to the feed inlet, Gate 1 on the storage roller 330 is exactly at the top, and when the storage roller 330 reaches the feed inlet 1101, Gate 1 is opened to receive the material; when the storage roller 330 moves to the discharge chute 440, Gate 1 on the storage roller 330 is exactly at the bottom, and when the storage roller 330 reaches the discharge chute 440, Gate 1 is opened to discharge the material.

[0156] It should also be noted that transmitters are installed on the gates 3303 of the storage drum 330, and receivers are installed at the feed inlet 1101. The receivers are located above the storage drum 330. When the storage drum 330 moves to the feed inlet 1101, the signal emitted by the transmitter is received by the receiver, indicating that the gate 3303 is located above, and the gate 3303 is opened. A receiver is installed at the discharge chute 440. The receivers are located below the storage drum 330. When the storage drum 330 moves to the discharge chute 440, the signal emitted by the transmitter is received by the receiver, indicating that the gate 3303 is located below, and the gate 3303 is opened.

[0157] It should also be noted that gravity detection can be used during material discharge. When the storage roller 330 moves to the discharge chute 440, the gate 3303 that bears the greatest gravity is opened, thereby ensuring that the gate 3303 located below the storage roller 330 is opened, achieving rapid material discharge. Furthermore, gravity detection is existing technology, and its specific working principle will not be elaborated in this application; for example, gravity detection can be performed by installing a gravity sensor on each gate 3303.

[0158] It should also be noted that the controller includes, but is not limited to, a PLC controller. The controller is electrically connected to the roller motor, the drive device 20, and the third conveying unit 430. When the storage roller 330 moves to the feed inlet 1101, the feed sensor generates a corresponding feed sensing electrical signal and transmits it to the controller. The controller controls the drive device 20 to stop working and controls the roller motor to open the upper gate 3303 of the storage roller 330 so that the items to be frozen can enter the storage device. When the preset feeding time interval t1 is reached, feeding stops. The controller controls the drive device 20 to continue working and controls the roller motor to close the upper gate 3303 of the storage roller 330. The drive device 20 drives the storage roller 330 to move toward the discharge port 1102. Of course, the preset feeding time interval t1 can be set as needed, and this application does not impose specific limitations.

[0159] When the storage roller 330 moves to the discharge trough 440, the discharge sensing element generates a corresponding discharge sensing electrical signal and transmits it to the controller. The controller controls the third conveying unit 430 to stop working and controls the roller motor to open the lower gate 3303, so that the items to be frozen in the storage roller 330 fall into the discharge trough 440. When the preset discharge time interval t2 is reached, the discharge stops. The controller controls the third conveying device to continue working and controls the roller motor to close the lower gate 3303 of the storage roller 330. The third conveying unit 430 drives the storage roller 330 to move towards the second conveying unit 420. Of course, the preset discharge time interval t2 can be set as needed. This application does not impose specific limitations. For example, the preset feeding time interval t1 and the preset discharge time interval t2 can be set to be equal, so that while one storage roller 330 is feeding, another storage roller 330 is discharging, ensuring the working cycle.

[0160] Example 5

[0161] This invention also provides a quick-freezing machine, including the quick-freezing machine transport structure of any embodiment of this invention, thereby having all the technical effects brought about by the technical solutions of the above embodiments.

[0162] It should be noted that the quick-freezing machine also includes a centrifugal fan, an evaporator, and a defrosting water pipe. The centrifugal fan is located inside the freezing channel 110 and above the drive unit 20. The evaporator is located on both sides of the centrifugal fan, and the defrosting water pipe is located above the evaporator.

[0163] The quick-freezing machine also includes multiple upper and lower air inlets located in the freezing channel 110. The upper air inlets are located above the storage device 30, and the lower air inlets are located below the storage device 30. One part of the air-cooled air is blown directly to the storage device 30 through the upper air inlet by a centrifugal fan; another part of the air-cooled air is blown to the storage device 30 through the lower air inlet, thereby achieving rapid freezing of the items to be frozen.

[0164] Example 6

[0165] like Figure 7 As shown, this embodiment of the invention also provides a control method for the transport structure of a quick-freezing machine, including:

[0166] S101: Open the storage device 30 at the feed inlet 1101 of the freezing channel 110 and put the items to be frozen into the storage device 30;

[0167] In some embodiments, opening the storage device 30 and inserting the items to be frozen into the storage device 30 at the feed inlet 1101 of the freezing channel 110 includes: sensing whether the storage device 30 has moved to the feed inlet 1101 by a feed sensor; if the storage device 30 has moved to the feed inlet 1101, then opening the cylinder door 3303 above the storage device 30.

[0168] It should be noted that the feeding sensor is located at the feed inlet 1101. The feeding sensor includes, but is not limited to, a proximity switch. When the feeding sensor is a proximity switch, the proximity switch can sense the approach of the storage roller 330. When the storage roller 330 approaches the proximity switch, the sensing distance decreases, thereby changing the state of the proximity switch and generating a corresponding feeding sensing electrical signal. The proximity switch includes, but is not limited to, photoelectric proximity switches, magnetic proximity switches, and ultrasonic proximity switches. For example, when the proximity switch is a photoelectric proximity switch, the photoelectric proximity switch uses the degree of light blocking by the object to sense the approach of the object. It includes a transmitter and a receiver. The transmitter emits a light beam. When the storage roller 330 approaches, the light beam is blocked, and the light signal received by the receiver is weakened, thereby generating a corresponding feeding sensing electrical signal, and the drum door 3303 opens.

[0169] It should also be noted that by controlling the opening of the upper door 3303 of the storage device 30, the lower door 3303 of the storage device 30 is prevented from opening, which could cause the items to be frozen to fall out of the storage device 30.

[0170] S102: After a preset feeding time interval, the storage device 30 is turned off;

[0171] It should be noted that the preset feeding time interval can be set according to specific needs. When the feeding time meets the preset feeding time interval, the cylinder door 3303 above the storage device 30 will close and feeding will stop.

[0172] S103: Start the drive device 20 to drive the storage device 30 to rotate and move along the length of the freezing channel 110 to freeze the items to be frozen;

[0173] In some embodiments, activating the drive device 20 to drive the storage device 30 to rotate and move along the length of the freezing channel 110 to freeze the items to be frozen specifically involves: activating the drive motor to drive the drive chain 2202 to rotate; and converting the motion of the drive chain 2202 into the rotation of the storage device 30 and its movement along the length of the freezing channel 110 through the transmission sprocket 320 of the storage device 30.

[0174] In some embodiments, the control method for the quick-freezing machine transport structure further includes: sensing whether the storage device 30 has moved to the discharge chute 440 by a discharge sensor; if the storage device 30 moves to the discharge chute 440, then opening the cylinder door 3303 of the storage device 30.

[0175] It should be noted that the discharge sensing element is located above the discharge trough 440. The discharge sensing element includes, but is not limited to, a proximity switch. When the discharge sensing element is a proximity switch, the proximity switch can sense the approach of the storage roller 330. When the storage roller 330 approaches the proximity switch, the sensing distance decreases, thereby changing the state of the proximity switch and generating a corresponding discharge sensing electrical signal. The proximity switch includes, but is not limited to, photoelectric proximity switches, magnetic proximity switches, and ultrasonic proximity switches. For example, when the proximity switch is a photoelectric proximity switch, the photoelectric proximity switch uses the degree of light blocking by the object to sense the approach of the object. It includes a transmitter and a receiver. The transmitter emits a light beam. When the storage roller 330 approaches, the light beam is blocked, and the light signal received by the receiver is weakened, thereby generating a corresponding discharge sensing electrical signal.

[0176] It should also be noted that when the storage device 30 moves to the discharge trough 440, it can open all the drum doors 3303 of the storage drum 330, or it can only open the drum door 3303 located at the bottom of the storage device 30, to ensure rapid discharge.

[0177] In some embodiments, the control method for the quick-freezing machine transport structure further includes: shutting down the storage device 30 after a preset discharge time interval;

[0178] It should be noted that the preset discharge time interval can be set according to specific needs, and the preset discharge time interval can be equal to the preset feeding time interval. When the discharge time meets the preset feeding time interval, the gate 3303 of the storage roller 330 is closed, and the discharge stops. At this time, the storage roller 330 is empty.

[0179] In some embodiments, the control method of the quick-freezing machine transport structure further includes: activating the third transport unit 430 to transfer the storage device 30 to the second transport unit 420.

[0180] It should be noted that activating the third conveying section 430 to transfer the storage device 30 to the second conveying section 420 specifically involves the third conveying section 430 including a chain conveyor.
