Description

Technical Field

[0001] The present invention relates to the technical field of freezing storage equipment, and in particular to a freezing storage equipment for cuttlefish ball samples. Background Art

[0002] After being produced, cuttlefish balls are at a relatively high temperature and often need to be cooled before the next process can be carried out. The traditional cooling method is slow, the cooling is insufficient, which reduces the work efficiency and increases the cooling cost.

[0003] After retrieval, the Chinese patent with the publication number CN207763312U discloses a cuttlefish ball cooler, which shortens the cooling stroke of cuttlefish ball products, and can reduce the power of the original cooling fan, reducing the production energy consumption. It adopts a feeding trough with a vibration mechanism. When the cuttlefish ball products fall from the upper conveying mechanism, they are guided by an arc-shaped guide plate into the vibrating table on the vibration mechanism. Due to vibration, they are scattered from each other and gradually pass through the baffle table, so that the number and position of cuttlefish ball products falling on each layer of the conveying mechanism are uniform. At the same time, the vibration mechanism can fully vibrate off the excess water on the surface of the cuttlefish ball products, eliminating the evaporation of water on the surface of the cuttlefish ball products by the cooling fan, and further improving the cooling efficiency.

[0004] Based on the above retrieval and in combination with the existing technology, it is found that: when cooling cuttlefish balls through a cooling fan, the cooling time is relatively long, and the taste of cuttlefish balls will also deteriorate due to the evaporation of water during the freezing process. When directly using gasified liquid nitrogen for cooling treatment, during the process of the cuttlefish balls being transported and moving along the conveying mechanism, the cuttlefish balls remain stationary, there are cooling dead angles, the freezing is not uniform, and it is easily limited by the size of the cuttlefish balls, affecting the overall quality of the cuttlefish balls and reducing the freezing storage efficiency of the cuttlefish ball samples.

[0014] The present invention provides a frozen storage device for cuttlefish ball samples through improvement. Compared with the prior art, it has the following improvements and advantages: First: By setting a rack, a box cover, a conveyor, a gear, a rack, a cooling rack, a first telescopic rod and a second telescopic rod, when the cuttlefish balls enter the inside of the cooling rack, they fall into the placement frame and are conveyed by the conveyor. During the conveying process, they vibrate up and down under the action of the support blocks distributed in a linear array on the cross bar, so that the gasified liquid nitrogen sprayed by the nozzle is cooled more evenly. When the placement frame is lifted by the support blocks, it also supports the cooling rack. When the placement frame separates from the support blocks and vibrates, the cooling rack is also loosened and vibrates, and the gasified liquid nitrogen sprayed by the nozzle is sprayed more evenly. When the gear moves with the conveyor, it meshes with the rack at the bottom of the cross bar, thereby driving the fan blades to rotate to disturb the air flow inside the rack, further improving the uniform freezing treatment of the cuttlefish balls. Moreover, the descending amplitude of the placement frame changes with the weight of the cuttlefish balls. The heavier the cuttlefish balls, the greater the vibration force; the lighter the cuttlefish balls, the smaller the vibration force, avoiding the phenomenon that the size of the cuttlefish balls changes, the weight is too heavy to vibrate normally, or the cuttlefish balls are shaken out due to too light weight, and improving the frozen storage efficiency of the cuttlefish ball samples; Second: By setting a placement frame, a convex block and an inclined plate, the cuttlefish balls vibrate in the placement groove for uniform freezing treatment. The convex block is arranged in the placement groove to support the cuttlefish balls, reducing the contact area between the cuttlefish balls and the placement frame, and further freezing the cuttlefish balls. The uniformly frozen cuttlefish balls fall into the storage box at the bottom of the rack. The cuttlefish balls falling on the inclined plate first slide to the left to avoid accumulation, further improving the frozen storage efficiency of the cuttlefish ball samples; Thirdly: In the present invention, by providing a baffle, a damping rotating shaft, a movable plate and a spring three, when the placement frame moves to the lower part of the feed pipe along with the conveyor, the movable plate connected to the bottom damping rotating shaft of the baffle is pressed by the previous placement frame, so that the baffle presses the spring three together with the movable plate, the baffle is separated from the feed pipe, and the fish balls just fall into the placement frame directly below the feed pipe. After the movement of the previous placement frame, the feeding of the next placement frame is completed, and the feeding of the fish balls is more stable and convenient.

[0022] Working principle: When conducting samples and frozen storage of cuttlefish balls, a batch of cuttlefish balls is directly placed into the feed pipe 4. The cuttlefish balls just enter the placement frame 13 through the feed pipe 4. Start the conveyor 10 in the support frame 2, and the conveyor 10 drives the placement frame 13 on the fixed plate 15 to move stably for the transportation of cuttlefish balls. After the cuttlefish balls enter the interior of the placement frame 13, the placement frame 13 descends a certain height under the influence of the gravity of the cuttlefish balls. The second telescopic rod 12 and the first spring 18 contract. When the placement frame 13 moves to the position of the cross bar 9, the placement frame 13 is in contact connection with the support block 22 on the cross bar 9. When the placement frame 13 continues to move with the conveyor 10, its edge is connected to the arc surface of the support block 22. The placement frame 13 is lifted and rises by the support block 22. At the same time, the placement frame 13 supports the cooling rack 23, so that the cooling rack 23 and the flow dividing plate 27 rise together. Liquid nitrogen is transported into the flow dividing pipe 25 through the action of the pump body, then enters the flow dividing plate 27 through the connecting hose 26, and finally is atomized and sprayed out through the nozzle 28. When the placement frame 13 moves and separates from the support block 22, the placement frame 13 vibrates rapidly under the action of gravity in cooperation with the second telescopic rod 12 and the first spring 18, thereby driving the cuttlefish balls placed inside the placement frame 13 to vibrate. The liquid nitrogen sprayed by the nozzle 28 can evenly freeze-treat it. When the placement frame 13 vibrates and separates from the support block 22, the cooling rack 23 supported and lifted by the placement frame 13 also vibrates rapidly and resets under the action of the first telescopic rod 8 and the second spring 24. The flow dividing plate 27 and the nozzle 28 on the cooling rack 23 vibrate up and down accordingly, so that the nozzle 28 vibrates and moves up and down rapidly, and the sprayed liquid nitrogen contacts the cuttlefish balls more dispersedly and evenly. When the fixed plate 15 moves close to the cross bar 9, the gear 17 in the mounting frame 16 on the fixed plate 15 meshes with the rack 21 on the cross bar 9. The gear 17 rotates accordingly, thereby driving the rotating rod 20 to rotate. The fan blade 19 on the rotating rod 20 rotates accordingly to disturb the air flow in the frame 1, further assisting in the uniform freezing treatment of the cuttlefish balls. When cuttlefish balls of different sizes and weights are placed inside the placement frame 13, the height at which the placement frame 13 descends due to gravity is different. The greater the weight of the cuttlefish balls, the lower the height of the placement frame 13, and the greater the vibration force after separating from the support block 22, adapting to the weight of large-sized cuttlefish balls. The smaller the gravity of the cuttlefish balls, the smaller the descent amount of the placement frame 13, and the smaller the vibration force after separating from the support block 22, adapting to the weight of small-sized cuttlefish balls, avoiding the phenomenon that the size of the cuttlefish balls changes, the weight is too heavy to vibrate normally, or the cuttlefish balls are shaken out due to too light weight.

[0023] The placement groove opened in the placement frame 13 is semicircularly arranged. The cuttlefish balls vibrate in the placement groove for uniform freezing treatment. Protrusions 14 are arranged in the placement groove to support the cuttlefish balls, reduce the contact area between the cuttlefish balls and the placement frame 13, and further freeze-treat the cuttlefish balls. The uniformly frozen cuttlefish balls fall into the storage box 7 at the bottom of the frame 1. The cuttlefish balls falling from the inclined plate 11 first slide to the left to avoid accumulation.

[0024] When the squid balls are placed inside the feeding pipe 4, they are first blocked by the baffle plate 29 and remain in the feeding pipe 4. When the placing frame 13 moves to the lower part of the feeding pipe 4 along with the conveyor 10, the previous placing frame 13 presses the movable plate 32 connected to the bottom damping rotating shaft 33 of the baffle plate 29, so that the baffle plate 29 presses the third spring 31 together with the movable plate 32, and the baffle plate 29 is separated from the feeding pipe 4. The squid balls just fall into the placing frame 13 directly below the feeding pipe 4. When the baffle plate 29 continues to move, the third spring 31 can no longer be compressed. At this time, the pressure received by the movable plate 32 is greater than the resistance of the damping rotating shaft 33, and the damping rotating shaft 33 drives the movable plate 32 to rotate. After the placing frame 13 is separated from the movable plate 32, the baffle plate 29 and the movable plate 32 are reset under the action of the third spring 31, and the bottom of the feeding pipe 4 is blocked again, which is convenient for the feeding of the next batch of squid balls.

The matters not covered in the present invention belong to the common general knowledge of those skilled in the art.
