Description

Technical Field

[0001] This utility model relates to the field of quick-frozen food processing technology, specifically a storage device for quick-frozen food processing. Background Technology

[0002] Quick-frozen food refers to fresh food that has been pre-treated and then rapidly frozen at extremely low temperatures. In particular, bagged quick-frozen dumplings need to be quick-frozen during processing to prevent food spoilage and ensure the stability of food quality, thus requiring the use of a storage device.

[0003] A Chinese patent with authorization announcement number CN221341758U discloses a storage device for quick-frozen food processing, including a quick-frozen food storage box body; a food separation unit movably installed inside the quick-frozen food storage box body; and a draining unit detachably installed at the bottom of the food separation unit. The food separation unit includes quick-frozen food separation and storage components movably installed inside the quick-frozen food storage box body. This utility model uses the food separation unit to store quick-frozen food and allows for adjustment of the storage space as needed. In conjunction with the draining unit, it collects and treats the thawing water drained from the quick-frozen food, thereby avoiding water accumulation that could damage the quick-frozen food, and thus improving the utilization efficiency of the device and the quality of quick-frozen food storage and transportation.

[0004] However, the above-mentioned storage device still has some problems. In practical applications, different types of frozen dumplings are usually stacked together and stored together, making them difficult to distinguish. Furthermore, the food in the storage container cannot be automatically transferred to the retrieval outlet. The entire cover needs to be opened to remove the frozen dumplings, causing the cold air inside the storage container to leak out and resulting in energy waste. Therefore, a storage device for frozen food processing is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a storage device for quick-frozen food processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The storage device for quick-frozen food processing of this utility model includes a storage cylinder, a rotating shaft is rotatably installed inside the storage cylinder, a support plate is installed at the bottom end of the rotating shaft, six partition plates are equidistantly installed on the top side of the support plate, one side of each partition plate is installed on the outside of the rotating shaft, a disc is installed at the bottom end of the rotating shaft on the outside of the support plate, four U-shaped grooves and arc-shaped grooves are respectively opened inside the disc, the U-shaped grooves and arc-shaped grooves are respectively arranged in a cross pattern, a servo motor is installed on the bottom side of the storage cylinder, a rotating shaft is installed at the output end of the servo motor, a fan-shaped disc matching the arc-shaped groove is installed on the outside of the rotating shaft, a connecting rod is installed on the bottom side of the fan-shaped disc, and a protruding rod matching the U-shaped groove is installed on the top side of one end of the connecting rod, thereby realizing independent and separate storage of quick-frozen food. A servo motor drives a rotating shaft, which in turn rotates a sector-shaped disk. The protruding rod on the bottom of the sector-shaped disk works in conjunction with the U-shaped groove and arc-shaped groove on the disk, allowing the rotating shaft to precisely drive the support plate and the partition plate to rotate. This rotates the required frozen food to the position of the extraction slot, preventing the frozen food from squeezing and sticking together, ensuring food quality, achieving precise extraction, reducing interference with other foods during extraction, and improving extraction efficiency.

[0007] Preferably, the storage cylinder has a retrieval slot at its bottom, and a sliding door is slidably installed inside the retrieval slot. A sliding groove is provided inside the bottom of the storage cylinder, communicating with the retrieval slot. The sliding door slides into the sliding groove, opening the retrieval slot. A handle is installed on one side of the sliding door. An air inlet is provided on the bottom side of the storage cylinder, and several ventilation holes are provided inside the support plate. Under gravity, the frozen food will naturally settle at the bottom of the storage cylinder. The operator only needs to slide the sliding door into the sliding groove using the handle to easily open the retrieval slot and retrieve the desired frozen food. This eliminates the need to fully open the storage cylinder, preventing significant loss of cold air, reducing energy consumption, and minimizing the impact of the external environment on other foods inside the storage cylinder, thus ensuring the quality of food storage.

[0008] Preferably, an mounting plate is installed on the outer side of the storage cylinder, a telescopic rod is installed on the top side of the mounting plate, a fixing plate is installed at the top of the actuating rod of the telescopic rod, a limiting ring is rotatably installed on the top side of the fixing plate outside the actuating rod of the telescopic rod, a cover plate is installed on one side of the limiting ring, and a locking screw is rotatably installed inside the limiting ring. One end of the locking screw abuts against the outer side of the actuating rod of the telescopic rod, allowing the height of the cover plate to be adjusted by the telescopic rod to accommodate storage cylinders of different heights. The rotatable installation of the limiting ring and the fixing plate, and the mutual abutment between the locking screw and the outer side of the actuating rod of the telescopic rod, allows the cover plate to rotate and be fixed flexibly, facilitating food storage for operators.

[0009] Preferably, the cover plate is equipped with an edge-enclosing airbag inside, and an air pump is installed on the top side of the cover plate. The output end of the air pump is connected to a connecting pipe, one end of which is connected to the edge-enclosing airbag. The input end of the air pump is connected to an air inlet pipe. When the cover plate is closed on the storage cylinder, the air pump draws in air through the air inlet pipe and delivers the air to the edge-enclosing airbag through the connecting pipe, causing the edge-enclosing airbag to expand and fit tightly against the inner wall of the storage cylinder. This effectively prevents the entry of outside air and moisture, ensuring a low-temperature environment inside the storage cylinder and improving the storage quality of frozen food.

[0010] Preferably, a viewing window is provided on the outer side of the storage cylinder directly above the take-out slot, and four connecting shafts are equidistantly rotatably mounted on the bottom side of the storage cylinder. Foot brake wheels are fitted on the bottom side of the connecting shafts. The viewing window allows for easy observation of whether the frozen food to be taken out is in the take-out slot. The connecting shafts and foot brake wheels enable the storage cylinder to be easily moved and fixed, and the storage position can be easily adjusted according to actual needs.

[0011] Preferably, a control panel is installed on the outside of the storage cylinder. The control panel is electrically connected to the electrical components on the inner wall of the device and is used to operate and control the electrical components inside the device. The control panel allows for convenient operation of electrical components such as servo motors and air pumps, and adjustment of the device's operating status, thus improving the convenience and safety of operation.

[0012] The advantages of this utility model are: 1. In this utility model, the servo motor drives the rotating shaft to rotate, and the fan-shaped disk on the rotating shaft rotates accordingly. The protruding rod slides along the U-shaped groove. When the protruding rod slides out of the U-shaped groove, it drives the rotating shaft to rotate, so that the fan-shaped disk rotates into the inside of the arc groove, so that the disk stops rotating. The rotating shaft drives the support plate and six partition plates to rotate, so that the area storing different frozen foods is rotated to the take-out slot position in sequence, so as to achieve precise take-out. 2. After the storage is completed, rotate the limiting ring to adjust the angle of the cover plate so that it is aligned with the opening of the storage cylinder. Then rotate the locking screw to press against the action rod of the telescopic rod to fix the position of the cover plate. Operate the telescopic rod through the control panel to shorten its action end, thereby driving the fixing plate and the limiting ring to descend, so that the cover plate seals the storage cylinder. After the cover plate is closed, if the gas inside the airbag is insufficient, start the air pump. The air pump draws in air through the air inlet pipe and delivers it to the edge airbag through the connecting pipe. After the edge airbag expands, it fits tightly against the inner wall of the storage cylinder to prevent outside air and moisture from entering and maintain a low temperature environment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figure 1-5As shown, a storage device for quick-frozen food processing includes a storage cylinder 1. A rotating shaft 2 is rotatably mounted through the inside of the storage cylinder 1. A support plate 201 is mounted at the bottom end of the rotating shaft 2. Six partition plates 202 are equidistantly mounted on the top side of the support plate 201. One side of each partition plate 202 is mounted on the outside of the rotating shaft 2. A disc 203 is mounted at the bottom end of the rotating shaft 2, located outside the support plate 201. The disc 203 has four U-shaped openings inside. The storage cylinder 1 has a U-shaped groove 204 and an arc-shaped groove 205, which are arranged in a cross pattern. A servo motor 206 is installed on the bottom side of the storage cylinder 1. A rotating shaft 207 is installed at the output end of the servo motor 206. A fan-shaped disk 208 that matches the arc-shaped groove 205 is installed on the outer side of the rotating shaft 207. A connecting rod 209 is installed on the bottom side of the fan-shaped disk 208. A protruding rod 210 that matches the U-shaped groove 204 is installed on the top side of one end of the connecting rod 209. The storage cylinder 1 has an inside of a take-out groove 3 at its bottom end. A sliding door 301 is slidably installed inside the take-out groove 3. A sliding groove 302 is provided inside the storage cylinder 1 at its bottom end, which is connected to the take-out groove 3. The sliding door 301 slides into the sliding groove 302, and the take-out groove 3 opens. A handle 303 is installed on one side of the sliding door 301. An air inlet is provided on the bottom side of the storage cylinder 1, and several ventilation holes are provided inside the support plate 201. A control panel 7 is installed on the outside of the storage cylinder 1. The control panel 7 is electrically connected to the electrical components on the inner wall of the device and is used to control the operation of the electrical components inside the device. In practical applications, different types of frozen dumplings are usually stacked together in cold storage, making them difficult to distinguish. Furthermore, the food in the storage cylinder 1 cannot automatically transfer to the retrieval outlet; the cover 404 must be completely opened to remove the frozen dumplings, causing cold air to leak out of the storage cylinder 1 and wasting energy. The six partitions 202 form six independent storage spaces, enabling separate storage of frozen foods and preventing the stacking of different types of frozen foods. The operator uses the control panel 7 to start... The servo motor 206 drives the rotating shaft 207 to rotate, and the sector disk 208 on the rotating shaft 207 rotates accordingly. The connecting rod 209 and the protruding rod 210 on the bottom side of the sector disk 208 cooperate with the U-shaped groove 204 and the arc groove 205 on the disc 203. The protruding rod 210 slides along the U-shaped groove 204. When the protruding rod 210 slides out of the U-shaped groove 204, it drives the rotating shaft 2 to rotate, so that the sector disk 208 rotates into the interior of the arc groove 205, so that the disc 203 stops rotating. The rotating shaft 2 drives the support plate 201 and the six partition plates 202 to rotate, so that the area storing different frozen foods is sequentially rotated to the position of the retrieval slot 3, so as to achieve precise retrieval. After the operator controls the servo motor 206 through the control panel 7 to rotate the target food to the position of the take-out slot 3, they hold the handle 303 on one side of the sliding door 301 and slide the sliding door 301 along the slide 302. When the sliding door 301 is completely slid into the slide 302, the take-out slot 3 opens, and the operator can easily take out the required frozen food. After taking out the food, the sliding door 301 is slid in the opposite direction to close the take-out slot 3 again. This operation avoids opening the storage cylinder 1 completely, greatly reducing the loss of cold air, reducing energy consumption, and reducing the impact of the external environment on other foods in the cylinder. Secondly, the cold air in the cold storage enters the interior of the storage cylinder 1 through the air inlet and is distributed above the support plate 201 through the ventilation holes to ensure the storage effect of the frozen dumplings. When the bagged frozen dumplings are stacked, it is necessary to avoid the bagged frozen dumplings from contacting the inner wall of the storage cylinder 1, so that there is a space gap between the frozen dumplings and the storage cylinder 1 for movement. This facilitates the rotation of the support plate 201 and the entry of cold air to ensure the cooling effect of the frozen dumplings.

[0018] Please see Figure 1 , 2 As shown in Figure 5, an installation plate 4 is installed on the outer side of the storage cylinder 1. A telescopic rod 401 is installed on the top side of the installation plate 4. A fixing plate 402 is installed at the top of the working rod of the telescopic rod 401. A limit ring 403 is rotatably installed on the top side of the fixing plate 402 outside the working rod of the telescopic rod 401. A cover plate 404 is installed on one side of the limit ring 403. A locking screw 405 is rotatably installed inside the limit ring 403. One end of the locking screw 405 abuts against the outer side of the working rod of the telescopic rod 401. The cover plate 404 is equipped with a perimeter airbag 5 inside, and an air pump 501 is installed on the top side of the cover plate 404. The output end of the air pump 501 is connected to a connecting pipe 502. One end of the connecting pipe 502 is connected to the perimeter airbag 5. The input end of the air pump 501 is connected to an air inlet pipe 503. A viewing window 6 is provided on the outer side of the storage cylinder 1, directly above the take-out slot 3. Four connecting shafts 601 are equidistantly rotatably installed on the bottom side of the storage cylinder 1, and foot brake wheels 602 are fitted on the bottom side of the connecting shafts 601. During operation, there will still be gaps after the cover plate 404 contacts the storage cylinder 1, which cannot fit tightly into the storage cylinder 1, resulting in energy waste. At the same time, the quality of frozen food will decline due to temperature fluctuations. When it is necessary to open the cover plate 404 to put the frozen food to be stored into the storage cylinder 1, the telescopic rod 401 is extended by controlling the control panel 7, the locking screw 405 inside the limit ring 403 is released, the tightness restriction on the telescopic rod 401 is released, and the angle of the cover plate 404 is adjusted by rotating the limit ring 403 so that it is offset from the opening of the storage cylinder 1, which facilitates the storage of frozen products. After storage, rotate the limiting ring 403 to adjust the angle of the cover plate 404 so that it is aligned with the opening of the storage cylinder 1. Then rotate the locking screw 405 to press against the action rod of the telescopic rod 401 to fix the position of the cover plate 404. Operate the telescopic rod 401 through the control panel 7 to shorten its action end, thereby driving the fixing plate 402 and the limiting ring 403 to descend, so that the cover plate 404 seals the storage cylinder 1. After the cover plate 404 is closed, if the gas inside the edge airbag 5 is insufficient, the air pump 501 is started. The air pump 501 draws in air through the air inlet pipe 503 and delivers it to the edge airbag 5 through the connecting pipe 502. After the edge airbag 5 expands, it fits tightly against the inner wall of the storage cylinder 1 to prevent outside air and moisture from entering and maintain a low temperature environment. The viewing window 6 is made of transparent material, allowing operators to observe whether the frozen food to be taken out has been rotated to the position of the taking out slot 3 without opening the taking out slot 3 or the cover plate 404. This facilitates preparation for taking out the food in advance. When the storage position needs to be adjusted, the brake device of the foot brake wheel 602 is released, and the storage cylinder 1 is pushed. The foot brake wheel 602 rolls to move the storage cylinder 1. After moving to the designated position, the brake device of the foot brake wheel 602 is depressed to fix the storage cylinder 1 and make it stable.

[0019] Working principle: When it is necessary to open the cover plate 404 to put the frozen food to be stored into the storage cylinder 1, the telescopic rod 401 is extended by controlling the control panel 7, the locking screw 405 inside the limit ring 403 is released, the restraint restriction on the telescopic rod 401 is released, and the limit ring 403 is rotated to adjust the angle of the cover plate 404 so that it is offset from the opening of the storage cylinder 1, which facilitates the storage of frozen products. After storage, rotate the limiting ring 403 to adjust the angle of the cover plate 404 so that it is aligned with the opening of the storage cylinder 1. Then rotate the locking screw 405 to press against the action rod of the telescopic rod 401 to fix the position of the cover plate 404. Operate the telescopic rod 401 through the control panel 7 to shorten its action end, thereby driving the fixing plate 402 and the limiting ring 403 to descend, so that the cover plate 404 seals the storage cylinder 1. After the cover plate 404 is closed, if the gas inside the edge airbag 5 is insufficient, the air pump 501 is started. The air pump 501 draws in air through the air inlet pipe 503 and delivers it to the edge airbag 5 through the connecting pipe 502. After the edge airbag 5 expands, it fits tightly against the inner wall of the storage cylinder 1 to prevent outside air and moisture from entering and maintain a low temperature environment. The viewing window 6 is made of transparent material. Operators can observe whether the frozen food to be taken out has been rotated to the position of the taking out slot 3 without opening the taking out slot 3 or the cover plate 404. This makes it easy to prepare for taking out the food in advance. When it is necessary to adjust the storage position, release the brake device of the foot brake wheel 602, push the storage cylinder 1, and the foot brake wheel 602 will roll to move it. After moving to the designated position, step on the brake device of the foot brake wheel 602 to fix the storage cylinder 1 and make it stable. Six partitions 202 form six independent storage spaces, enabling separate storage of frozen foods and preventing the accumulation of different types of frozen foods. The operator starts the servo motor 206 through the control panel 7. The servo motor 206 drives the rotating shaft 207 to rotate, and the sector disk 208 on the rotating shaft 207 rotates accordingly. The connecting rod 209 and the protruding rod 210 on the bottom side of the sector disk 208 cooperate with the U-shaped groove 204 and the arc groove 205 on the disc 203. The protruding rod 210 slides along the U-shaped groove 204. When the protruding rod 210 slides out of the U-shaped groove 204, it drives the rotating shaft 2 to rotate, causing the sector disk 208 to rotate into the interior of the arc groove 205, causing the disc 203 to stop rotating. The rotating shaft 2 drives the support plate 201 and the six partitions 202 to rotate, and the areas storing different frozen foods are sequentially rotated to the position of the retrieval slot 3 to achieve precise retrieval. After the operator controls the servo motor 206 through the control panel 7 to rotate the target food to the position of the take-out slot 3, they hold the handle 303 on one side of the sliding door 301 and slide the sliding door 301 along the slide 302. When the sliding door 301 is completely slid into the slide 302, the take-out slot 3 opens, and the operator can easily take out the required frozen food. After taking out the food, the sliding door 301 is slid in the opposite direction to close the take-out slot 3 again. This operation avoids opening the storage cylinder 1 completely, greatly reducing the loss of cold air, reducing energy consumption, and reducing the impact of the external environment on other foods in the cylinder. Secondly, the cold air in the cold storage enters the interior of the storage cylinder 1 through the air inlet and is distributed above the support plate 201 through the ventilation holes to ensure the storage effect of the frozen dumplings. When the bagged frozen dumplings are stacked, it is necessary to avoid the bagged frozen dumplings from contacting the inner wall of the storage cylinder 1, so that there is a space gap between the frozen dumplings and the storage cylinder 1 for movement. This facilitates the rotation of the support plate 201 and the entry of cold air to ensure the cooling effect of the frozen dumplings.
