Description

Technical Field

[0001] The present invention relates to the technical field of cooling devices, and particularly relates to a rapid cooling device for quick-frozen prepared foods. Background Art

[0002] Quick-frozen prepared foods refer to packaged foods that use agricultural products, livestock and poultry, aquatic products, etc. as the main raw materials, are processed through preliminary treatment and formulation, and then use the quick-freezing process and are stored, transported, and sold in a frozen state. Quick-frozen prepared foods can be divided into two types: raw frozen and cooked frozen. Eggs are a kind of food rich in nutrients. After the eggs are fried and quick-frozen, and then packaged, the edible shelf life can be extended.

[0003] An existing rapid cooling device for quick-freezing scrambled eggs (Publication No.: CN219460238U) has at least the following drawbacks: The above patent flattens the fried eggs on the conveyor belt and cooperates with several fans to swing back and forth to blow air on the scrambled eggs to achieve the purpose of rapid cooling, which is convenient for subsequent quick-freezing and conditioning of scrambled eggs. At the same time, the turning shaft can turn the scrambled eggs on the conveyor belt to make the cooling of the scrambled eggs more uniform; since the scrambled eggs are flat on the conveyor belt, the fan can only blow air and cool the upper side of the scrambled eggs, resulting in the side of the scrambled eggs in contact with the conveyor belt not being able to cool down quickly, affecting the subsequent quick-freezing and refrigeration treatment effect of the scrambled eggs. Summary of the Invention

[0008] As a further solution of the present invention, the movable guide mechanism includes a plurality of support rods fixedly mounted on the lower surface of the top plate, guide blocks are fixedly mounted between the bottom ends of the plurality of support rods, two guide blocks are provided with a clearance groove on the adjacent side close to the feeding pipe, a guide groove is provided on the outer surface of the guide block close to the clearance groove, the end of the T-frame is abutted against the outer surface of the guide block, a guide column is fixedly mounted on the end of the T-frame close to the guide block, and the guide column is slidably mounted on the inner wall of the guide groove.

[0011] As a further solution of the present invention, a dehumidification component is installed on the lower surface of the top plate, and the dehumidification component includes a suction fan fixedly installed on the lower surface of the top plate, and the suction fan is arranged above the cooling water tank.

[0012] As a further solution of the present invention, a sealing assembly for sealing the packaging bag is installed on the outer surface of the guide block away from the feeding pipe, and the sealing assembly includes a plurality of mounting rods fixedly mounted on the outer surface of one adjacent side of the two guide blocks, and a heat sealer is fixedly mounted on the end of the plurality of mounting rods away from the guide block.

[0013] As a further solution of the present invention, a mounting groove is formed through the outer surface of the guide block, and a hair dryer is fixedly mounted on the inner wall of the mounting groove.

[0028] Refer to the attached Figure 1 - Attached Figure 7, A rapid cooling device for quick-frozen prepared foods, comprising a base 1 and a packaging bag. A plurality of upright columns 2 are fixedly installed at the top end of the base 1. The top ends of the plurality of upright columns 2 are fixedly installed with a top plate 3. Two sets of conveying mechanisms are installed on the lower surface of the top plate 3. A synchronization component is installed between the two sets of conveying mechanisms. The synchronization component includes synchronization gears 23 respectively fixedly installed at the rotation centers of two corresponding sprockets 4 in the two sets of conveying mechanisms. The two synchronization gears 23 are meshed with each other. A stepping motor 24 is fixedly installed on the upper surface of the top plate 3. The output end of the stepping motor 24 penetrates through the lower surface of the top plate 3 and is fixedly installed with the rotation center of one of the sprockets 4. The conveying mechanism includes two sprockets 4 rotatably installed on the lower surface of the top plate 3. A conveying chain 5 is sleeved on the outer surfaces of the two sprockets 4. A plurality of mounting plates 6 are fixedly installed at equal intervals on the outer side of the conveying chain 5. An adsorption and limiting mechanism for supporting the packaging bag is installed on the mounting plate 6. A feeding pipe 12 is fixedly installed through the upper surface of the top plate 3. A feeding hopper 13 is fixedly installed at the top end of the feeding pipe 12. A cooling water tank 14 is fixedly installed on the upper surface of the base 1. The adsorption and limiting mechanism includes two first spring rods 7 fixedly installed on the inner side of the mounting plate 6. The telescopic ends of the two first spring rods 7 are fixedly installed with second spring rods 8. A T-shaped frame 9 is fixedly installed between the telescopic ends of the two second spring rods 8. A plurality of electric suction cups 10 are fixedly installed on the outer surface of the T-shaped frame 9. A moving and guiding mechanism for pushing the T-shaped frame 9 is installed on the lower surface of the top plate 3 close to each set of conveying mechanisms. The moving and guiding mechanism includes a plurality of support rods 15 fixedly installed on the lower surface of the top plate 3. A guide block 16 is fixedly installed between the bottom ends of the plurality of support rods 15. A relief groove 21 is opened on the adjacent side of the two guide blocks 16 close to the feeding pipe 12. A guide groove 22 is opened on the outer surface of the guide block 16 close to the relief groove 21. The end of the T-shaped frame 9 abuts against the outer surface of the guide block 16. A guide post 11 is fixedly installed at the end of the T-shaped frame 9 close to the guide block 16. The guide post 11 is slidably installed with the inner wall of the guide groove 22. The relief groove 21 is a trapezoidal structure. The relief groove 21 includes a relief section 211, a translation section 212, and a compression section 213. The relief groove 21 is successively composed of the relief section 211, the translation section 212, and the compression section 213. The guide groove 22 includes a first upper section 221, a sinking section 222, a cooling section 223, a floating section 224, and a second upper section 225. The guide groove 22 is successively composed of the first upper section 221, the sinking section 222, the cooling section 223, the floating section 224, and the second upper section 225.

[0029] When in use, one of the sprocket wheels 4 is driven to rotate by the stepper motor 24. Since the two sets of conveying mechanisms are installed through the synchronous gear 23, the two sets of conveying mechanisms can drive the corresponding adsorption and limiting mechanisms to move synchronously relative to each other. At the end close to the feed hopper 13, a packaging bag is placed between the two sets of relatively arranged adsorption and limiting mechanisms by a robotic arm, so that the adsorption and limiting mechanisms adsorb both sides of the bag opening of the packaging bag, so that the relatively arranged adsorption and limiting mechanisms can drive the packaging bag to move in the direction of the feeding pipe 12. When the T-frame 9 moves to the giving section 211 of the giving groove 21, the telescopic end of the first spring rod 7 will drive the T-frame 9 to move outward, so that the electric suction cup 10 installed on the T-frame 9 can pull the bag opening of the packaging bag to both sides, so that the bag opening of the packaging bag is opened, so that the quick-frozen prepared food can be subsequently fed through the feeding tube 12. The feeding tube 12 is put into the packaging bag; when the T-shaped frame 9 moves to the translation section 212, the bag mouth of the packaging bag is always in an open state. At this time, a certain amount of quick-frozen prepared food is put into the feeding hopper 13, so that the quick-frozen prepared food falls into the packaging bag through the feeding tube 12. After the quick-frozen prepared food is put into the packaging bag, the guide column 11 installed at the end of the T-shaped frame 9 will move from the first upper section 221 to the sinking section 222, so that the T-shaped frame 9 pulls the telescopic end of the second spring rod 8 to move downward, so that the electric suction cup 10 drives the bottom of the packaging bag containing the quick-frozen prepared food to sink into the cooling water of the cooling water tank 14, so that the cooling water cools the quick-frozen prepared food in the packaging bag. As the adsorption limit mechanism drives the packaging bag to continue to move, the guide column 11 will translate at the cooling section 223, so that the packaging bag always moves in the cooling water.

[0030] In this embodiment, a dehumidification assembly is installed on the lower surface of the top plate 3 , and the dehumidification assembly includes a suction fan 17 fixedly installed on the lower surface of the top plate 3 . The suction fan 17 is arranged above the cooling water tank 14 .

[0031] When in use, the suction fan 17 installed on the top plate 3 can suck out the hot steam emitted by the quick-frozen prepared food in the packaging bag to prevent the hot steam from forming water droplets in the packaging bag and soaking the quick-frozen prepared food, thereby affecting the taste of the quick-frozen prepared food.

[0032] In this embodiment, a sealing assembly for sealing the packaging bag is installed on the outer surface of the guide block 16 away from the feeding tube 12, and the sealing assembly includes a plurality of mounting rods 19 fixedly mounted on the outer surface of the adjacent side of the two guide blocks 16, and a heat sealer 20 is fixedly mounted on the end of the plurality of mounting rods 19 away from the guide block 16.

[0033] When the adsorption limiting mechanism drives the packaging bag to move horizontally between the two heat sealers 20 arranged opposite to each other, the heat sealer 20 will perform plastic sealing on the bag opening of the packaging bag so that the packaged quick-frozen prepared food can be directly placed in the cooling cabinet for refrigeration.

[0034] In this embodiment, a mounting groove is formed through the outer surface of the guide block 16 , and a hair dryer 18 is fixedly mounted on the inner wall of the mounting groove.

[0035] When the packaging bag passes through the hair dryer 18 installed on the guide block 16, the hair dryer 18 can blow off the water droplets adhering to the surface of the packaging bag to keep the surface of the packaging bag dry, so that the quick-frozen prepared food packed in the packaging bag can be directly placed in the cooling cabinet for refrigeration, and the hair dryer 18 can further cool the quick-frozen prepared food in the packaging bag.

[0036] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, one of the sprockets 4 is driven to rotate by the stepping motor 24. Since the two groups of conveying mechanisms are installed through the synchronous gear 23, the two groups of conveying mechanisms can drive the corresponding adsorption and limiting mechanisms to move synchronously relative to each other. At the end close to the feed hopper 13, a packaging bag is placed between the two groups of relatively arranged adsorption and limiting mechanisms by a robotic arm, so that the adsorption and limiting mechanisms adsorb both sides of the bag opening of the packaging bag, so that the relatively arranged adsorption and limiting mechanisms can drive the packaging bag to move in the direction of the feeding pipe 12. When the T-frame 9 moves to the giving section 211 of the giving groove 21, the telescopic end of the first spring rod 7 will drive the T-frame 9 to move outward, so that the electric suction cup 10 installed on the T-frame 9 can pull the bag opening of the packaging bag to both sides, so that the bag opening of the packaging bag is opened, so that the quick-frozen prepared food can be subsequently put into the packaging bag through the feeding pipe 12; when the T-frame 9 moves to the flat When the quick-frozen prepared food is put into the packaging bag, the guide column 11 installed at the end of the T-shaped frame 9 will move from the first upper section 221 to the sinking section 222, so that the T-shaped frame 9 pulls the telescopic end of the second spring rod 8 to move downward, so that the electric suction cup 10 drives the bottom of the packaging bag containing the quick-frozen prepared food to move downward. The guide post 11 will be partially sunk into the cooling water in the cooling water tank 14, so that the cooling water cools the quick-frozen prepared food in the packaging bag. As the adsorption limit mechanism drives the packaging bag to continue to move, the guide post 11 will translate at the cooling section 223, so that the packaging bag always moves in the cooling water. At the same time, the suction fan 17 installed on the top plate 3 can absorb the hot steam emitted by the quick-frozen prepared food in the packaging bag, so as to prevent the hot steam from forming water droplets in the packaging bag and soaking the quick-frozen prepared food, thereby affecting the taste of the quick-frozen prepared food.

[0037] When the guide post 11 moves to the floating section 224, the adsorption and limiting mechanism will drive the whole packaging bag to be lifted out of the cooling water tank 14; when the guide post 11 moves to the second upper section 225, the adsorption and limiting mechanism will drive the packaging bag to move horizontally, so that the water adhering to the surface of the packaging bag will naturally drip into the cooling water tank 14; at the same time, when the packaging bag passes by the hair dryer 18 installed on the guide block 16, the hair dryer 18 can blow off the water droplets adhering to the surface of the packaging bag, keeping the surface of the packaging bag dry, so that the quick-frozen prepared food packed in the packaging bag can be directly put into the cooling cabinet for refrigeration, and the hair dryer 18 can further cool down the quick-frozen prepared food in the packaging bag;

[0038] When the adsorption and limiting mechanism drives the packaging bag to move horizontally to the position between two relatively arranged heat sealers 20, the heat sealers 20 will seal the bag mouth of the packaging bag, so that the quick-frozen prepared food packed can be directly put into the cooling cabinet for refrigeration;

[0039] While the two relatively arranged adsorption and limiting mechanisms installed on the two conveying mechanisms are separated from each other, the electric suction cup 10 will no longer adsorb the packaging bag, so that the packaging bag loses support and drops into the collection box under its own weight for collection.

[0040] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
