Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, specifically a shrimp box tray packaging device. Background Technology

[0002] In the production, sales and transportation of shrimp products, shrimp boxes and trays serve as an important carrier for shrimp products. The efficiency and quality of their packaging work directly affect the operation of the entire industry chain. With the continuous expansion of the shrimp consumption market, the demand for shrimp box and tray packaging is also increasing. Traditional packaging methods and existing packaging equipment are gradually revealing many problems.

[0003] In many small packaging sites or temporary operations, manual packing of shrimp box pallets is extremely common. Workers need to manually arrange the pallets one by one, and then put on and seal the packing materials. The whole process depends entirely on manual operation, which is tedious and labor-intensive. Some companies have introduced simple semi-automatic packing equipment. These devices usually have basic pallet conveying functions and can transport shrimp box pallets to designated workstations. However, subsequent core operations such as pallet stacking, precise opening and closing of packing bags, and wrapping still require manual intervention. The equipment only plays an auxiliary role in conveying.

[0004] However, in the manual packaging mode, the speed of workers' operation is limited by physiological limits, and long-term repetitive work easily leads to fatigue, resulting in a significant reduction in packaging efficiency. When faced with large-scale orders, manual packaging simply cannot complete the task on time, seriously hindering the production progress. Although simple semi-automatic equipment provides some assistance, key packaging links still rely on manual labor, and the overall efficiency improvement is limited. Traditional automated equipment has technical shortcomings in pallet stacking and precise wrapping of packaging bags, and cannot achieve fast, continuous, and efficient packaging, making it difficult to keep up with the current fast-paced industrial development.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution for a shrimp box tray packaging device:

[0021] The workbench 1 includes a material conveying mechanism on one side of its top. A limiting platform 12 is fixedly connected to the top of the workbench 1 on one side of the material conveying mechanism. A first fixing frame 2 is fixedly installed on the top of the workbench 1. A guide rail 3 is laid on the top of the first fixing frame 2. A movable plate 18 is slidably connected to the inner side of the guide rail 3. A first suction cup 19 is symmetrically connected to the bottom of the movable plate 18. A second fixing frame 6 is provided on one side of the first fixing frame 2. The second fixing frame 6 is fixedly connected to the top of the workbench 1. A connecting plate 5 is installed on the top of the second fixing frame 6. A protective frame 4 is fixedly connected between the connecting plates 5. A roller 25 is rotatably connected inside the protective frame 4. A packing bag is wound around the outside of the roller 25. A packing bag is installed inside the second fixing frame 6. There is a first electric telescopic rod 7, and a second connecting block 26 is fixedly installed at the output end of the first electric telescopic rod 7. A suction plate 8 is slidably connected to the inner side of the second connecting block 26 in a symmetrical structure. A third electric telescopic rod 28 is installed between the suction plates 8. Multiple sets of second suction cups 29 are fixedly connected to the inner side of the suction plate 8. A lifting plate 10 is movably connected inside the limiting platform 12. A fixed frame 20 is fixedly installed at the bottom of the worktable 1. A second motor 21 is installed on one side of the fixed frame 20. A bidirectional threaded rod 22 is coaxially fixedly connected to the output end of the second motor 21. A connecting rod 23 is threadedly connected to the outer side of the bidirectional threaded rod 22 in a symmetrical structure. A plastic sealing block 11 is fixedly installed at the end of the connecting rod 23. The plastic sealing block 11 is located above the lifting plate 10.

[0022] Specifically, the conveying mechanism transports the shrimp box trays to below the first fixed frame 2. The movable plate 18 slides on the guide rail 3, and the first suction cups 19 symmetrically connected to its bottom sequentially adsorb the shrimp box trays and stack them on the limiting platform 12. When the preset stacking quantity is reached, the stacked shrimp box trays are moved above the lifting plate 10. The roller 25 inside the protective frame 4 on the second fixed frame 6 winds the packaging bag. The first electric telescopic rod 7 is activated, and the second connecting block 26 at its output end drives the suction plate 8 to descend. The third electric telescopic rod 28 installed between the suction plates 8 extends, causing the suction plates 8 to unfold. At the same time, multiple sets of second suction cups 29 on the inner side of the suction plate 8 adsorb the edge of the packaging bag opening. As the first electric telescopic rod 7 continues to descend, the packaging bag is pulled downward, and the third electric telescopic rod 28 causes the suction plate 8 to unfold further, thereby fully opening the packaging bag opening. The open packaging bag is moved to the top of the stacked shrimp box tray. At this time, the lifting plate 10 rises, raising the position of the tray so that the packaging bag can be gradually put on the tray. As the lifting plate 10 rises, the suction plate 8 drives the packaging bag to completely wrap the tray. When the wrapping is in place, the second suction cup 29 stops adsorbing the packaging bag. The second motor 21 on one side of the fixed frame 20 starts, and the bidirectional threaded rod 22 at its output end rotates, so that the connecting rod 23 with the outer symmetrical threaded connection drives the sealing block 11 to move towards each other. The sealing block 11 is equipped with a heating element to facilitate the sealing of the opening of the packaging bag, completing the entire packaging process. The shrimp box tray is automatically transported by the conveying mechanism. The movable plate 18 cooperates with the first suction cup 19 to achieve rapid stacking, reducing the time for manual handling and stacking, greatly improving the efficiency of lunch box sorting, and adapting to the needs of large-scale production.

[0023] The first fixed frame 2 is fixedly connected to the inner side of the limiting frame 14. The first motor 16 is fixedly connected to one side of the limiting frame 14. The output end of the first motor 16 is fixedly connected to the lead screw. The slider 15 is slidably connected inside the limiting frame 14. The slider 15 is threadedly connected to the lead screw. The inner side of the slider 15 is fixedly connected to the cylinder 27. The output end of the cylinder 27 is connected to the clamping plate 17. The limiting platform 12 is provided with a slot 13 for use with the plastic sealing block 11 and the connecting rod 23.

[0024] Specifically, the limiting frame 14 provides a stable sliding track for the slider 15, ensuring its precise movement. The first motor 16 drives the lead screw to rotate, thereby controlling the position of the slider 15 within the limiting frame 14. This design allows the clamping plate 17 to be flexibly adjusted according to different sizes of shrimp box trays, accurately positioned to the edge of the tray, achieving adaptable clamping for products of different specifications, improving the versatility of the equipment, and avoiding packaging difficulties caused by changes in tray size. When the slider 15 moves to the appropriate position, the cylinder 27 is activated, and its output end pushes the clamping plate 17 to clamp the shrimp box tray. The clamping plate 17 can provide a stable clamping force, ensuring that the shrimp are properly clamped during subsequent stacking, packaging bag placement, and other processes. The box tray will not shift or shake, ensuring the stability and accuracy of the packaging process and preventing problems such as uneven packaging and deviated sealing position caused by tray movement. The slot 13 is designed to cooperate with the movement of the sealing block 11 and the connecting rod 23. During the sealing process, the sealing block 11 and the connecting rod 23 need to move towards each other above the limiting platform 12 to complete the sealing of the opening of the packaging bag. The slot 13 provides them with movement space, ensuring that the sealing block 11 can smoothly approach and contact the opening of the packaging bag to achieve a tight sealing operation. At the same time, the movement of the connecting rod 23 in the slot 13 is also smoother, avoiding interference with the limiting platform 12 and ensuring the stability and reliability of the sealing process.

[0025] The bottom of the lifting plate 10 is provided with a second electric telescopic rod 9, which is fixed to the bottom of the workbench 1. The inner side of the second fixed frame 6 is provided with an movable groove for use with the second connecting block 26, and the first connecting block 24 is fixedly connected in a symmetrical structure inside the protective frame 4. The roller 25 is rotatably connected to the first connecting block 24.

[0026] Specifically, the second electric telescopic rod 9 can precisely control the rising and falling height of the lifting plate 10. During the process of placing the packaging bag on the stacked shrimp box tray, the position of the lifting plate 10 can be flexibly adjusted according to the size of the packaging bag and the stacking height of the tray, ensuring that the packaging bag can be accurately wrapped from the bottom of the tray upwards, improving the accuracy of packaging, and avoiding problems such as incomplete or misaligned packaging due to unsuitable height. When it is necessary to replace the packaging bag roll 25 of different specifications or used up, since the roll 25 is rotatably connected to the first connecting block 24, the operator can easily remove the old roll 25 and quickly install the new roll 25. The symmetrical structure of the first connecting block 24 design can maintain the balance of the entire structure during the replacement of the roll 25, which is convenient for operation, improves the efficiency of packaging bag replacement, and reduces equipment downtime.

[0027] The working principle of this utility model is as follows:

[0028] First, the feeding mechanism activates, transporting the shrimp box trays to below the first fixed frame 2. Simultaneously, the movable plate 18 slides along the guide rail 3, and the first suction cup 19 connected to its bottom performs an adsorption function, sequentially adsorbing the shrimp box trays and neatly stacking them on the limiting platform 12. During this process, the limiting frame 14, the first motor 16, the lead screw, the slider 15, the cylinder 27, and the clamping plate 17 work together. The first motor 16 drives the lead screw to rotate, causing the slider 15 to move precisely within the limiting frame 14, thereby allowing the clamping plate 17 to flexibly adjust its position according to the size of the shrimp box trays. When the slider 15 is in position, the cylinder 27 pushes the clamping plate 17 to clamp the tray, ensuring the tray's position is stable during stacking and preventing displacement or shaking.

[0029] Secondly, once the preset stacking quantity is reached, the stacked shrimp box trays are moved above the lifting plate 10. At this time, the packaging bag preparation stage is started. The roller 25 inside the protective frame 4 on the second fixed frame 6 is stably unrolled by rotating with the first connecting block 24 of the symmetrical structure. The first electric telescopic rod 7 is activated, and the second connecting block 26 at its output end moves precisely down along the movable groove on the inner side of the second fixed frame 6, causing the suction plate 8 to descend. The third electric telescopic rod 28 between the suction plates 8 extends, causing the suction plate 8 to unfold. The second suction cup 29 on its inner side adsorbs the edge of the packaging bag opening. As the first electric telescopic rod 7 continues to descend, the packaging bag is pulled down, and the third electric telescopic rod 28 further unfolds the suction plate 8, fully opening the packaging bag opening.

[0030] It is worth mentioning that the precise control of the height of the lifting plate 10 by the second electric telescopic rod 9 can flexibly adjust the position according to the size of the packaging bag and the stacking height of the pallet, ensuring that the packaging bag is accurately wrapped from the bottom of the pallet, which greatly improves the packaging accuracy. In addition, the movable groove on the inner side of the second fixing frame 6 provides stable guidance for the second connecting block 26, ensuring that the suction plate 8 and the packaging bag move smoothly and avoiding situations such as poor suction and uneven opening, which effectively ensures the packaging quality. Furthermore, the slot 13 provides sufficient space for the opposite movement of the sealing block 11 and the connecting rod 23, ensuring that the sealing operation is tight and stable, avoiding interference, and improving the reliability of the sealing process.

[0031] Finally, the opened packaging bag is moved above the stacked shrimp box tray. The lifting plate 10 rises under the action of the second electric telescopic rod 9, raising the position of the tray so that the packaging bag is gradually placed on the tray. As the lifting plate 10 continues to rise, the suction plate 8 drives the packaging bag to completely wrap the tray. After wrapping, the second suction cup 29 stops suction. Then, the second motor 21 on one side of the fixed frame 20 starts, and the bidirectional threaded rod 22 at its output end rotates, driving the connecting rod 23 with symmetrical threaded connection on the outside, so that the sealing blocks 11 at the end move towards each other. Since the sealing block 11 is equipped with a heating element, when the sealing block 11 contacts the edge of the opening of the packaging bag, the high temperature melts the plastic material and applies pressure. After cooling, the opening of the packaging bag is sealed, and the entire packaging process ends.

[0032] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
