Description

Technical Field

[0001] This invention relates to the field of conveying device technology, specifically to an automated conveying device for food cold chain. Background Technology

[0002] The food cold chain refers to a special supply chain system in which perishable foods are kept at the necessary low temperature environment at every stage from acquisition or harvesting at the place of origin to processing, storage, transportation, distribution and retail, and finally to the consumer, in order to ensure food quality and safety, reduce losses and prevent contamination. It consists of four aspects: frozen processing, frozen storage, refrigerated transportation and distribution, and frozen sales.

[0003] Ice transport is a crucial link in the front end of the cold chain. After being produced by the ice maker, ice blocks are neatly transported by a tilting machine to a plate conveyor, then from the plate conveyor to a chain conveyor, and finally to the appropriate location. In existing technology, to ensure a smooth transition of ice blocks to the chain conveyor, an arc-shaped baffle and an inclined guide rod are typically added to the end of the plate conveyor. However, during the transport process, the continuous squeezing and pushing force from the rear ice blocks causes collisions and friction between the front ice blocks and the arc-shaped baffle. This collision and friction easily leads to chipping and damage at the contact points, forming grooves. Therefore, ice blocks can easily get stuck at the end of the plate conveyor, preventing them from smoothly entering the chain conveyor. At this point, workers need to manually pull out the stuck ice blocks using hooks or other tools to prevent further ice block transport. This requires dedicated personnel to monitor the process, increasing labor costs and affecting the continuity of transport in industrial food processing. Summary of the Invention

[0004] The purpose of this invention is to provide an automated conveying device for food cold chain, which solves the problem mentioned in the background art where ice blocks collide and rub against the arc-shaped baffle, forming grooves that cause ice blocks to easily get stuck at the end of the plate conveyor and fail to enter the chain conveyor smoothly. This requires manual unblocking, which not only increases labor costs but also affects the continuity of conveying and production efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated food cold chain conveying device, comprising an ice block turning machine, a plate conveyor, and a chain conveyor.

A sliding cylinder is slidably sleeved on the outside of the end of the second transmission shaft away from the second sliding groove. The transmission groove is formed at one end of the mounting frame. The sliding cylinder is slidably mounted inside the transmission groove.

[0009] Preferably, the unhooking mechanism includes a fixed bracket, which is fixedly connected to the lifting rod. A limit frame is slidably installed on the top of the fixed bracket. A second spring is fixedly installed between the side of the limit frame near the fixed bracket and the inner wall of the fixed bracket. A third spring is fixedly installed between the bottom of the fixed bracket and the mounting block. A positioning component is provided on the top of the fixed bracket.

[0010] Preferably, the positioning component includes a positioning rod, a top rod, and a positioning groove. The positioning groove is formed at one end of the top of the limiting frame. The positioning rod is slidably connected to the fixed bracket, and the bottom end of the positioning rod cooperates with the positioning groove. The top rod is fixedly installed on one side of the mounting frame, and the inclined surface of the top rod and the positioning rod cooperates with each other.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The set hook mechanism, driven by the drive mechanism, automatically pulls the ice blocks stuck at the end of the plate conveyor, allowing the ice blocks to smoothly enter the chain conveyor. At the same time, two hooks are set up, which are used alternately, eliminating the need for manual handling of stuck ice blocks and eliminating the need for dedicated personnel to be on duty. In the industrial processing of food, this reduces labor costs and ensures the continuity of ice block transportation.

[0014] The designed unhooking mechanism prevents the hook from rotating downwards during its repositioning process, thus avoiding pulling the ice block backwards. Simultaneously, the distance between the two mounting blocks increases during their repositioning movement, preventing them from contacting each other when they move closer together, thereby ensuring the proper operation of subsequent structures.

The drive end of the drive motor 34 is fixedly connected to the end of one of the lead screws 33. A guide rod 35 is provided above each of the two lead screws 33. The two guide rods 35 are fixedly installed inside the mounting frame 6. Two movable seats 10 are threaded onto the outside of the two lead screws 33, and the top of the two movable seats 10 is respectively fitted onto the outside of their respective guide rods 35. A pulley 36 is fixedly fitted onto one end of each of the two lead screws 33, and the two pulleys 36 are connected by a belt.

[0026] Working principle: When in use, ice cubes are first conveyed to the top of plate conveyor 2 by ice cube flipping machine 1. By operating plate conveyor 2, ice cubes can be conveyed to the top of chain conveyor 3. Finally, ice cubes can be conveyed to the appropriate position by chain conveyor 3. The setting of guide rod 5 and arc baffle 4 can ensure that the ice cubes at the top of plate conveyor 2 are guided and conveyed to the top of chain conveyor 3. When the ice block at the top of the plate conveyor 2 is stuck at the position of the arc-shaped baffle 4 and cannot move to the chain conveyor 3, the drive motor 34 is started. Under the action of the two pulleys 36, the two lead screws 33 rotate simultaneously. At the same time, under the action of the two guide rods 35, the two moving seats 10 move relative to each other. The movement process of one of the moving seats 10 and the corresponding hook mechanism and unhooking mechanism is as follows: When the moving seat 10 moves, it drives the corresponding mounting block 11 to move synchronously. The hooks 15 in the mounting block 11 move synchronously. During the process of the mounting block 11 moving towards the drive motor 34, the transmission shaft 21 first drives the sliding cylinder 22 in the corresponding transmission groove 23. The ice block slides downward inside until it moves horizontally. At this time, since the bottom of the limit frame 25 is located at the bottom of the transmission shaft 21, when the transmission shaft 21 moves downward along the transmission groove 23, the transmission shaft 21 drives the lifting rod 19 and the transmission shaft 18 to move downward synchronously. The transmission shaft 18 slides inside the slide groove 17, and the connecting rod 16 is forced to drive the connecting shaft 14 and the hook 15 to rotate. During this process, the hook 15 gradually inserts into the top of the ice block. When the transmission shaft 21 moves to the horizontal position of the transmission groove 23, with the operation of the drive mechanism, the hook 15 can pull one end of the ice block from the plate conveyor 2 to the top of the chain conveyor 3. When the second drive shaft 21 moves to the inclined position at the other end of the drive groove 23, the second drive shaft 21 gradually moves upward, thereby causing the lifting rod 19 and the first drive shaft 18 to move upward. The hook 15 gradually resets and detaches from the ice block, allowing the ice block to be conveyed forward under the action of the chain conveyor 3. When the limit frame 25 contacts the mounting frame 6, as the mounting block 11 moves, the limit frame 25 is pushed away from the drive motor 34 by the mounting frame 6 and squeezes the second spring 26. When the positioning groove 30 corresponds to the positioning rod 28, the positioning rod 28 is inserted downward into the interior of the positioning groove 30 under the action of the fourth spring 31, and the position of the limit frame 25 is fixed. As the limit frame 25 moves, the bottom end of the limit frame 25 moves away from the second drive shaft 21. At this time, the lifting rod 19 is located at the top under the action of the third spring 27. As the limit bracket 25 moves, one end of the top pull rod 32 moves synchronously. Under the action of the pull rod 32, the mounting block 11 and its components move towards one side of the movable seat 10. The mounting block 11 drives the two sliding rods 12 to slide, the spring 13 is compressed, and one end of the transmission shaft 21 also extends and retracts inside the sliding cylinder 22. (It should be noted that when the mounting block 11 moves towards the corresponding movable seat 10, the distance between it and the other mounting block 11 increases. Therefore, when the two mounting blocks 11 move closer to each other, they will not contact each other, thus ensuring the normal operation of the subsequent structures.) Subsequently, the drive motor 34 reverses, and the movable seat 10 and the mounting block 11 move in the opposite direction. Since the bottom end of the limit frame 25 is no longer located below the second transmission shaft 21, the second transmission shaft 21 will still move up and down according to the shape of the transmission groove 23. At this time, the second transmission shaft 21 only moves up and down inside the second slide groove 20 and will not drive the lifting rod 19 to move up and down. Therefore, the hook 15 remains in the upward position to prevent the hook 15 from pulling the ice block down and moving in the opposite direction during the reset process. As the drive motor 34 continues to reverse, when one side of the positioning rod 28 contacts the top rod 29, the positioning rod 28 is forced to move upward, and its bottom is separated from the positioning groove 30. The limit frame 25 is reset under the action of the second spring 26, and its bottom end is located at the bottom of the second transmission shaft 21 again, thereby ensuring the normal operation of the next operation. This invention, through a hook mechanism, automatically pulls ice blocks stuck at the end of the plate conveyor 2 under the action of the drive mechanism, allowing the ice blocks to smoothly enter the chain conveyor 3. At the same time, two hooks 15 are also provided, which are used alternately, eliminating the need for manual handling of stuck ice blocks and eliminating the need for dedicated personnel to be on duty. In the industrial processing of food, this reduces labor costs and ensures the continuity of ice block transportation. By rotating the adjusting screw 9, the mounting frame 6 and the two hooks 15 therein can be moved up and down, thereby adjusting the distance between the two hooks 15 and the ice block to ensure the best performance of the two hooks 15.
