Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, specifically relating to a modified atmosphere packaging device for chilled whitebait. Background Technology

[0002] Large whitebait is a popular aquatic food, prized for its delicate texture and delicious taste. Modified atmosphere packaging (MAP), a novel packaging technology, is increasingly being used to preserve aquatic products. By adjusting the composition of the gas inside the packaging, such as reducing oxygen and increasing the proportion of carbon dioxide or nitrogen, MAP can effectively inhibit the growth of microorganisms such as bacteria and mold, slow down the spoilage and oxidation of aquatic products, and thus extend their shelf life.

[0003] In the prior art, patent publication number CN217396990U describes an intelligent modified atmosphere packaging device for meat products. This patent includes a main body with multiple drive rollers connected to a conveyor belt carrying packaging boxes. The main body also has multiple first telescopic cylinders connected to a mounting frame at their tops. Second telescopic cylinders are housed within the mounting frame, and mounting plates are connected to the bottoms of the second telescopic cylinders. Multiple connecting rods are connected to the bottom of the mounting plate, and corresponding heat-sealing mechanisms are mounted on the bottoms of the connecting rods. The heat-sealing mechanisms are connected to the packaging boxes. Correspondingly, the bottom of the mounting frame is equipped with a connecting plate and a support roller. The connecting plate is equipped with a retractable air jet head. The left and right sides of the mounting frame are respectively equipped with a film receiving roller and a film releasing roller. After the film passes around the support roller, it passes between the air jet head and the heat sealing mechanism. This device can perform modified atmosphere sealing better. However, in actual use, there are still the following shortcomings: From a practical point of view, after packaging food, the device still needs to be manually removed one by one. It is not convenient to collect multiple packaging boxes in a centralized manner, and the whole production process becomes cumbersome. Especially when dealing with a large number of packaging boxes, it will significantly increase the working time and affect the overall work efficiency.

[0004] Therefore, a modified atmosphere packaging device for chilled whitebait is needed to solve the problem of manual removal of the packaging box, which affects the overall work efficiency in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a modified atmosphere packaging device for chilled whitebait to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modified atmosphere packaging device for chilled whitebait, comprising a positioning plate, a bottom box fixedly connected to the top of the positioning plate, a worktable fixedly connected to the top of the bottom box, two conveyor belts installed on the top of the worktable, multiple limiting grooves fixedly connected to the top of each of the two conveyor belts, a storage box sleeved on the inner wall of the top of each pair of corresponding limiting grooves, a side plate fixedly connected to the top of the outer wall of each of the multiple storage boxes, a modified atmosphere packaging machine fixedly connected to the top of the worktable near the front end, and a collection mechanism provided on the top of the worktable near the rear end.

[0007] It should be noted in the solution that the positioning plate has multiple positioning and mounting holes on its surface.

[0008] It is worth noting that anti-slip pads are fixedly connected to the inner walls of multiple limiting grooves.

[0009] It should be further noted that the modified atmosphere packaging machine has observation windows on both sides.

[0010] In a preferred embodiment, the collecting mechanism includes multiple L-shaped frames inserted into the top of the workbench. A concave frame is fixedly connected between every two corresponding L-shaped frames. A support plate is fixedly connected to the inner side of the two concave frames near the top. A handle is fixedly connected to the top of the support plate. Multiple rotating shafts are fixedly connected between the inner walls of the front and rear ends of the two concave frames. Two bushings are rotatably connected to the outer walls of the multiple rotating shafts. A baffle is fixedly connected to the outer walls of the multiple bushings. An overlapping interface is opened near the inner side of the top of the multiple baffles. A semi-circular opening is opened near the outer side of the top of the multiple baffles. Multiple round rods corresponding to the semi-circular openings are fixedly connected between the inner walls of the front and rear ends of the two concave frames. A cylinder is fixedly connected to the bottom of the workbench. A push plate is fixedly connected to the output end of the cylinder through the workbench.

[0011] In one preferred embodiment, the top of the workbench is provided with multiple insertion slots corresponding to the L-shaped frame.

[0012] In a preferred embodiment, the outer diameter of the push plate is smaller than the inner diameter of the limiting groove.

[0013] Compared with the prior art, the modified atmosphere packaging device for chilled whitebait provided by this utility model has at least the following beneficial effects:

[0014] (1) By setting up a collection mechanism, after the fresh whitebait inside the storage box is packaged, it moves with the conveyor belt to the bottom of the cylinder. The cylinder drives the push plate to rise, and the push plate pushes the storage box inside the limiting groove upward and through multiple baffles. Since the baffles can only rotate in one direction, the storage box can be stably placed on the top of multiple overlapping interfaces. As the work progresses, with the cooperation of the top column, the cylinder drives the push plate to push multiple storage boxes upward in sequence. Multiple packaging boxes can be arranged in order from top to bottom according to the order of sample injection, which greatly reduces manual intervention, improves the speed and efficiency of packaging production, and significantly improves work efficiency.

[0015] (2) By setting multiple limiting slots, it is convenient to limit the placement of the storage box, prevent the storage box from being moved or deviating from the predetermined position on the worktable, and ensure that each storage box can enter the modified atmosphere packaging machine according to the correct trajectory, thus avoiding errors or inappropriate operations in the packaging process due to position deviation.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-5This utility model provides a modified atmosphere packaging device for chilled whitebait, including a positioning plate 1, a bottom box 2 fixedly connected to the top of the positioning plate 1, a worktable 3 fixedly connected to the top of the bottom box 2, two conveyor belts 4 installed on the top of the worktable 3, multiple limiting grooves 5 fixedly connected to the top of each of the two conveyor belts 4, a storage box 6 sleeved on the inner wall of the top of each pair of corresponding limiting grooves 5, and a side plate 7 fixedly connected to the top of the outer wall of each of the multiple storage boxes 6, a modified atmosphere packaging machine 8 fixedly connected to the top of the worktable 3 near the front end, and a collection mechanism 9 set on the top of the worktable 3 near the rear end.

[0024] Further as Figure 1 and Figure 2 As shown, it is worth noting that the positioning plate 1 has multiple positioning mounting holes on its surface. These holes help to fix the device in the correct position during installation, preventing the overall stability of the device from being affected by loose parts or inaccurate positioning. This ensures that the entire system is more secure during operation and avoids displacement caused by vibration or external forces.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the inner walls of multiple limiting grooves 5 are all fixedly connected with anti-slip pads. The anti-slip pads can provide stronger friction, reduce the risk of items sliding or shifting during transportation or handling, ensure that the storage box 6 maintains a stable position in the limiting groove, and prevent misalignment or damage caused by sliding.

[0026] Further as Figure 1 and Figure 2 As shown, it is worth noting that both sides of the modified atmosphere packaging machine 8 are equipped with observation windows. These windows allow operators to monitor the status of the items during the packaging process in real time, ensuring smooth packaging operations, timely detection of any problems or abnormalities, and timely adjustment or correction to reduce operational errors.

[0027] As can be seen from the above working process, by setting multiple limiting slots 5, it is convenient to limit the placement of the storage box 6, prevent the storage box 6 from being moved or deviating from the predetermined position on the worktable 3, and ensure that each storage box 6 can enter the modified atmosphere packaging machine 8 according to the correct trajectory, thus avoiding errors or inappropriate operations in the packaging process due to position deviation.

[0028] Further as Figure 4 and Figure 5As shown, it is worth noting that the collecting mechanism 9 includes multiple L-shaped frames 901 inserted into the top of the workbench 3. A concave frame 902 is fixedly connected between every two corresponding L-shaped frames 901. A support plate 903 is fixedly connected to the inner side of each concave frame 902 near its top. A handle 904 is fixedly connected to the top of the support plate 903. Multiple rotating shafts 905 are fixedly connected between the inner walls of the front and rear ends of each concave frame 902. Two bushings 906 are rotatably connected to the outer walls of each rotating shaft 905. Baffles 907 are fixedly connected to the outer walls of each bushing 906. The top of each baffle 907... The workbench 3 has an overlap interface 908 near the inner side, and a semi-circular opening 909 is provided on the top of multiple baffles 907 near the outer side. Multiple round rods 910 corresponding to the semi-circular openings 909 are fixedly connected between the inner walls of the front and rear ends of the two concave frames 902. A cylinder 911 is fixedly connected to the bottom of the workbench 3. A push plate 912 is fixedly connected to the output end of the cylinder 911 through the workbench 3. By setting up the collection mechanism 9, multiple packaging boxes can be arranged in order from top to bottom according to the order of sample feeding, which greatly reduces manual intervention, improves the speed and efficiency of packaging production, and significantly improves work efficiency.

[0029] Further as Figure 4 and Figure 5 As shown, it is worth noting that the top of the workbench 3 has multiple insertion slots corresponding to the L-shaped frame 901. These slots allow multiple L-shaped frames 901 to be easily inserted into the workbench 3, thus forming a flexible work area. This modular design facilitates the adjustment and expansion of the equipment, and allows for quick configuration and replacement according to different needs, providing greater work flexibility.

[0030] Further as Figure 4 and Figure 5 As shown, it is worth noting that the outer diameter of the push plate 912 is smaller than the inner diameter of the limiting groove 5, which ensures that the push plate 912 can pass smoothly through the limiting groove 5 during operation without being stuck or obstructed, thereby lifting and collecting samples inside multiple storage boxes 6.

[0031] This solution has the following working process: In actual use, multiple storage boxes 6 containing chilled whitebait are placed sequentially in multiple limiting grooves 5 at the top of the conveyor belt 4. As the conveyor belt 4 moves, they enter the modified atmosphere packaging machine 8 to complete the freshness-locking sealing. After sealing, the storage boxes 6 continue to move and move to the area directly below the cylinder 911. The cylinder 911 drives the push plate 912 to rise, and the push plate 912 pushes the storage boxes 6 inside the limiting grooves 5 upwards, passing through multiple baffles 907. Since the baffles 907 can only rotate in one direction, the storage boxes 6 can be stably placed on the top of multiple overlapping interfaces 908. As the work progresses, the cylinder 911 drives the push plate 912 to push the multiple storage boxes 6 upwards sequentially. The multiple storage boxes 6 can be arranged in order from top to bottom according to the order of sample injection.

[0032] In summary: By setting multiple limiting slots 5, the placement of the storage box 6 is conveniently limited, preventing unnecessary displacement or deviation from the predetermined position of the storage box 6 on the worktable 3, ensuring that each storage box 6 can enter the modified atmosphere packaging machine 8 along the correct trajectory, avoiding errors or inappropriate operations in the packaging process due to positional deviation; by setting the collection mechanism 9, multiple packaging boxes can be arranged sequentially from top to bottom according to the sample feeding order, greatly reducing manual intervention, improving the speed and efficiency of packaging production, and significantly improving work efficiency.

[0033] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
