Technical Field

[0001] The invention relates to the technical field of cooling devices, and in particular 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. After preliminary processing and preparation, they are quick-frozen and 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 frying and quick-freezing the eggs and then packaging them, their shelf life can be extended.

[0003] An existing rapid cooling device for quick freezing of scrambled eggs (Announcement No.: CN219460238U) has at least the following disadvantages: the above patent spreads the scrambled eggs flat on a conveyor belt, cooperates with a number of fans to swing back and forth, and blows air on the scrambled eggs to achieve the purpose of rapid cooling, which is convenient for subsequent quick freezing of the scrambled eggs. At the same time, the turning shaft can turn the scrambled eggs on the conveyor belt to make the scrambled eggs cool more evenly; because the scrambled eggs are spread flat on the conveyor belt, the fan can only blow air to cool the upper side of the scrambled eggs, resulting in the side of the scrambled eggs in contact with the conveyor belt cannot be quickly cooled, affecting the subsequent quick freezing and refrigeration treatment effect of the scrambled eggs.

[0008] As a further solution of the present invention, the give way groove is a trapezoidal structure, and the give way groove includes a give way section, a translation section and a compression section, and the give way groove is composed of the give way section, the translation section and the compression section in sequence.

[0009] As a further solution of the present invention, the guide groove includes a first upper section, a sinking section, a cooling section, a floating section and a second upper section, and the guide groove is composed of the first upper section, the sinking section, the cooling section, the floating section and the second upper section in sequence.

[0011] 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.

[0012] 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.

A mobile guide mechanism for pushing the T-shaped frame 9 is installed on the lower surface of the top plate 3 near each group of conveying mechanisms. The mobile guide mechanism includes a plurality of support rods 15 fixedly installed on the lower surface of the top plate 3, and a guide block 16 is fixedly installed between the bottom ends of the plurality of support rods 15. The two guide blocks 16 are provided with a clearance groove 21 on the adjacent side near the feeding pipe 12, and a guide groove 22 is provided on the outer surface of the guide block 16 near the clearance groove 21. The end of the T-shaped frame 9 is against the outer surface of the guide block 16, and the T-shaped A guide column 11 is fixedly installed at the end of the frame 9 close to the guide block 16, and the guide column 11 is slidably installed with the inner wall of the guide groove 22. The give way groove 21 is a trapezoidal structure, and the give way groove 21 includes a give way section 211, a translation section 212 and a compression section 213. The give way groove 21 is composed of the give way section 211, the translation section 212 and the compression section 213 in sequence. 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 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 in sequence.

[0020] 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.

[0021] 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 .

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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. When the guide post 11 moves to the upper floating section 224, the adsorption limiting mechanism will drive the packaging bag to be lifted out of the cooling water tank 14 as a whole; when the guide post 11 moves to the second upper section 225, the adsorption 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 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 later, and the hair dryer 18 can further cool the quick-frozen prepared food in the packaging bag; When the adsorption limit mechanism drives the packaging bag to move horizontally to 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 later; When the two oppositely disposed adsorption limit mechanisms installed on the two conveying mechanisms are separated from each other, the electric suction cup 10 will no longer adsorb the packaging bag, causing the packaging bag to lose support and fall into the collection box for collection under its own weight.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
