[0031] Based on the above-mentioned disclosed structure, when fish products are quickly frozen:

[0032] First, according to the thickness of the fish product to be frozen, the distance between the bottom of flattening plate 3 and the top of first conveying mechanism and the distance between the inner side of limiting plate 19 and the end of turnover guide plate 20 are adjusted, and the specific operation is as follows: start electric push rod 21 to push out telescopic end to make U-shaped carriage 2 slide along the conveying direction of first conveying mechanism, so that the two groups of slide grooves 22 on the both sides of U-shaped carriage 2 drive two first sliding rods 24 and two second sliding rods 25 respectively, two second sliding rods 25 drive flattening plate 3 to rotate in box 1, so as to increase the distance between the bottom of flattening plate 3 and the top of first conveying mechanism, and at the same time, two first sliding rods 24 drive limiting plate 19 to rotate on the top of fixed guide plate 18, so as to increase the distance between the inner side of limiting plate 19 and the end of turnover guide plate 20, so that the distance between the bottom of flattening plate 3 and the top of first conveying mechanism and the distance between the inner side of limiting plate 19 and the end of turnover guide plate 20 can only be increased by single layer or single each time;

[0033] Then the first conveying mechanism and the second conveying mechanism are started, and the liquid nitrogen spray pipe 23 sprays atomized liquid nitrogen, and then the fish products to be frozen are added into the feeding hole 4 at the top of the box 1, the fish products move along with the first conveying mechanism, and only pass through a single layer or a single fish product when passing through the bottom of the spreading plate 3, so that the fish products are automatically spread on the first conveying mechanism, and the atomized liquid nitrogen sprayed by the liquid nitrogen spray pipe 23 above the first conveying mechanism quickly freezes the fish products, after the fish products move to the end of the first conveying mechanism, the fish products move above the turnover guide plate 20, and then slide along the surface of the turnover guide plate 20 to the bottom end of the turnover guide plate, the distance between the inner side of the limiting plate 19 and the turnover guide plate 20 can only pass through a single layer or a single fish product, so that the fish products fall in a single or single layer form to the fixed guide plate 18, and then slide along the inner side of the fixed guide plate 18 to the second conveying mechanism, at this time, the fish products are transported upward on the second conveying mechanism with the side adhering to the top of the first conveying mechanism, and the atomized liquid nitrogen sprayed by the liquid nitrogen spray pipe 23 above the second conveying mechanism quickly freezes the side of the fish products adhering to the first conveying mechanism, so as to realize double-sided quick freezing, and the freezing effect is better and the freezing efficiency is higher;

[0034] Finally, the frozen fish products move to the end of the second conveying mechanism to push the baffle 5, and then are discharged from the discharge hole 6 and collected, and the baffle 5 can reduce the overflow of cold air in the box 1 and reduce waste.

[0035] In addition, according to the different extension lengths of the electric push rod 21, the device can be suitable for different types and different thicknesses of fish products, and the practicability is increased.

[0036] In addition, in order to prevent the fish products from adhering after being frozen, the following structure is preferably provided:

[0037] The turnover guide plate 20 is rotationally connected with a rotating plate 17 at the bottom, the rotating plate 17 is fixedly installed with a plurality of springs 15 at the bottom, and the plurality of springs 15 are fixedly installed with a knocking plate 16 at the bottom.

[0038] A guide groove 26 is formed on one side of the rotating plate 17, a rotating column 9 is rotationally connected on one side of the box 1, a fixed rod 27 is fixedly installed on one end of the rotating column 9, and the fixed rod 27 is slidingly fitted in the guide groove 26.

[0039] From the above, the fish products are prone to freeze adhesion when frozen on the first conveying mechanism, and it is inconvenient to take the frozen fish products individually. The device drives the fixed rod 27 to rotate around the axis of the rotating column 9, and the fixed rod 27 drives the rotating plate 17 to reciprocate up and down on the bottom of the turnover guide plate 20 through the guide groove 26, so as to drive the knocking plate 16 to vibrate up and down through the spring 15, so as to knock the fish products that have fallen from the fixed guide plate 18 to the second conveying mechanism, so as to separate the adhered fish products. Since the edges of the fish products on the second conveying mechanism have been frozen into shape, the adhesion is less, so that the frozen fish products are convenient to take individually. In addition, the spring 15 has a buffering effect of moving to avoid excessive knocking force and damage to the fish products.

[0040] In addition, regarding the driving of the first conveying mechanism, the second conveying mechanism and the rotating column 9, the following structure is preferably provided:

[0041] The first conveying mechanism comprises two first rotating shafts 11 connected in turn in the conveying direction in the box body 1, and a first conveying belt 13 sleeved outside the two first rotating shafts 11;

[0042] The second conveying mechanism comprises two second rotating shafts 8 connected in turn in the conveying direction in the box body 1, and a second conveying belt 14 sleeved outside the two second rotating shafts 8;

[0043] One of the first rotating shafts 11 and the rotating column 9 outside are coaxially fixed with a pulley 12, and the two pulleys 12 are rotatably connected with a belt 10. One of the second rotating shafts 8 and the rotating column 9 outside are coaxially fixed with a gear 7, and the two gears 7 are meshingly connected.

[0044] A motor 28 is fixedly installed on one side of the box body 1, and the output shaft of the motor 28 is fixedly connected with one end of one of the second rotating shafts 8.

[0045] From the above, the motor 28 is started to drive the corresponding second rotating shaft 8 to rotate, so as to drive the second conveying belt 14 to rotate through the friction between the second rotating shaft 8 and the second conveying belt 14, and then drive the other second rotating shaft 8 to rotate. At the same time, one of the second rotating shafts 8 drives the rotating column 9 to rotate through the transmission of the two gears 7, and then drives the corresponding first rotating shaft 11 to rotate through the transmission of the rotating column 9 and the pulley 12 and the belt 10 outside the first rotating shaft 11. In this way, the rotating column 9 and the corresponding first rotating shaft 11 rotate synchronously, and then the other first rotating shaft 11 is driven to rotate through the first conveying belt 13. In this way, one driving motor is used to drive the first rotating shaft 11 and the second rotating shaft 8 to rotate in opposite directions, so as to realize different direction conveying of the first conveying mechanism and the second conveying mechanism, and drive the rotating column 9 to rotate, so as to reduce the manufacturing cost of the equipment.

[0046] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
