Description

Technical Field

[0001] This utility model relates to the field of vacuum structure technology, and in particular to a gantry-type vacuum lifting structure. Background Technology

[0002] With increasing demands for product packaging quality, vacuum technology has been gradually applied to the processing of bulk bags. Vacuuming effectively removes air from the bag, reducing the impact of oxygen and moisture on the material, extending its shelf life, and simultaneously reducing internal pressure, resulting in a more secure seal and improved packaging sealing and stability. However, early vacuum equipment had a relatively simple structure, typically placing the bulk bag in a fixed vacuum chamber and using a vacuum pump to remove the air.

[0003] In existing technologies, some vacuuming devices may only employ a single-directional adsorption method. For example, adsorption may only occur from the top or side. If adsorption is only from the top, when the material distribution inside the ton bag is uneven or the material moves slightly during vacuuming, the top adsorption force alone may not be sufficient to hold the ton bag in place, causing it to tilt. Similarly, adsorption from the side alone presents a similar problem, failing to comprehensively restrict the displacement of the ton bag. Existing adsorption mechanisms may lack the ability to flexibly adjust the adsorption position and force. For example, the position of the adsorption plate may be fixed and cannot be adaptively adjusted according to the actual size and shape of the ton bag. When encountering ton bags of different specifications, the adsorption effect will be significantly reduced. Moreover, if the adsorption mechanism cannot adjust the adsorption force as needed, it may result in weak adsorption for heavier or irregularly shaped ton bags. Therefore, those skilled in the art have provided a gantry-type vacuum lifting structure to solve the aforementioned problems. Utility Model Content

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the solution comprises a first adsorption mechanism and a second adsorption mechanism working in tandem.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 — Figure 4The gantry-type vacuum lifting structure includes a sealed outer shell 1. A vacuum chamber 25 is formed on the inner wall of the sealed outer shell 1. A conveying mechanism 13 is installed near one side of the inner wall of the vacuum chamber 25. A conveying plate 14 is slidably connected to the top center of the conveying mechanism 13. The top of the conveying plate 14 is used to place the ton bag to be vacuumed. A second adsorption mechanism 15 is installed on one side of the top center of the conveying plate 14. A sliding groove 16 is formed in the middle of both side walls of the second adsorption mechanism 15. A lead screw 17 is rotatably connected to the middle of the inner wall of the sliding groove 16. A drive motor 21 is connected to the input end of the lead screw 17. The drive motor 21 is installed at the top center of the second adsorption mechanism 15. A lifting block 18 is threadedly connected to the sliding end of the lead screw 17. A third cylinder 19 is installed in the middle of one side wall of the lifting block 18, near the ton bag. An adsorption plate 20 is connected to the output end of the third cylinder 19.

[0022] The structure mainly includes a sealed outer shell 1, with a vacuum chamber 25 formed on the inner wall of the sealed outer shell 1, providing a closed space for vacuuming operations. A sealing top plate 2 is installed on the top of the sealed outer shell 1 to further enhance the sealing performance.

[0023] An installation plate 7 is installed on the inner wall of the vacuum chamber 25, located on one side of the conveying mechanism 13. An installation frame 8 is installed at the top center of the installation plate 7. A lifting adjustment mechanism 9 is slidably connected to the middle of the inner wall of the installation frame 8. A first adsorption mechanism 10 is installed at the top center of the lifting adjustment mechanism 9. A second cylinder 12 is slidably connected to the top center of the first adsorption mechanism 10. An adsorption plate 20 is connected to the output end of the second cylinder 12. The conveying mechanism 13 is installed on one side of the inner wall of the vacuum chamber 25, and a conveying plate 14 is slidably connected to its top for placing ton bags. A second adsorption mechanism 15 is provided on one side of the top of the conveying plate 14. Through the cooperation of the slide 16, lead screw 17, drive motor 21, lifting block 18, third cylinder 19, and adsorption plate 20, the adsorption position and force can be flexibly adjusted. Meanwhile, on the other side of the conveying mechanism 13, the first adsorption mechanism 10 is installed through the mounting plate 7, the mounting frame 8, and the lifting adjustment mechanism 9. The top of the first adsorption mechanism 10 is connected to the second cylinder 12 to drive the adsorption plate 20 to adsorb the ton bag from the top, and work together with the second adsorption mechanism 15 to stabilize the ton bag.

[0024] Sealing and Lifting: Lifting mechanism mounting frames 3 are installed on the front and rear side walls of the sealing housing 1. The first cylinder 6 on the frame is connected to the mounting component, which drives the lifting sealing door 5 to rise and fall along the limit slider 4, achieving sealing during the entry and exit of ton bags and vacuuming. The sealing bracket 11 at the bottom of the lifting mechanism mounting frame 3 is sealed to the lifting sealing door 5, further improving the sealing performance.

[0025] Vacuuming and control: The vacuum pump 23 on the mounting base 22 on one side of the sealed housing 1 is responsible for vacuuming, and the controller 24 on the other side of the sealed housing 1 is electrically connected to each component to realize automated control.

[0026] The first adsorption mechanism 10 and the second adsorption mechanism 15 work together in multiple directions to ensure that the ton bag is stable during the vacuuming process, avoiding displacement or tipping, thus improving work stability and efficiency. The perfect sealing system effectively prevents air from entering and ensures the vacuum level. The quick sealing and opening design improves operational efficiency and quality. The controller 24 realizes automated control, reducing manual labor and error rate, and improving production consistency and reliability. The integrated layout of various components reduces the floor space and facilitates installation, maintenance and operation. At the same time, the high degree of functional integration reduces equipment costs and failure risks.

[0027] Working Principle: The gantry-type vacuum lifting structure mainly consists of a sealed outer shell 1 and numerous internal components. These components work together to achieve vacuuming of the ton bags. The sealing top plate 2 at the top of the sealed outer shell 1 and the surrounding lifting and sealing doors 5 remain closed, ensuring the vacuum chamber 25 is sealed. The ton bag is placed on the conveyor plate 14, and the conveying mechanism 13 sends it into the vacuum chamber 25. After being conveyed to the correct position, the adsorption operation begins. The second adsorption mechanism 15 on the conveyor plate 14 is activated, driving the drive motor 21 to rotate the lead screw 17, causing the lifting block 18 to move along the slide 16, adjusting the height of the adsorption plate 20. The third cylinder 19 extends, allowing the adsorption plate 20 to adsorb the ton bag.

[0028] At this time, the first adsorption mechanism 10 and the second adsorption mechanism 15 work closely together. The lifting and adjusting mechanism 9 in the mounting frame 8 on the mounting plate 7 drives the first adsorption mechanism 10 to descend. Based on the adsorption position of the ton bag by the second adsorption mechanism 15, the first adsorption mechanism 10 extends through the second cylinder 12 to precisely adjust the position of the top adsorption plate 20, adsorbing the ton bag from above. The two work together to ensure that the ton bag is firmly adsorbed at multiple points, facilitating subsequent operations.

[0029] Subsequently, the sealing operation is initiated. The lifting mechanism mounting frames 3 on the front and rear side walls of the sealing outer shell 1 come into play. The first cylinder 6 on the frame pushes the mounting component, causing the lifting sealing door 5, which is bolted to it, to slide down along the limit slider 4, closing the inner compartment. The sealing bracket 11 at the bottom of the lifting mechanism mounting frame 3 fits tightly against the lifting sealing door 5, further ensuring the sealing of the inner compartment.

[0030] Next, the vacuuming process begins. The vacuum pump 23 on the mounting base 22 on one side of the sealed outer casing 1 starts working, extracting air from the vacuum chamber 25 to create a vacuum environment. The entire operation is precisely controlled by the controller 24. It is electrically connected to the vacuum pump 23, the first cylinder 6, the second cylinder 12, the third cylinder 19, and the drive motor 21. Through the controller 24, the operator can set the operating parameters and sequence of each component. For example, the rotation time and speed of the drive motor 21 can be preset to precisely control the lifting height of the adsorption plate 20; the stroke of the first cylinder 6 can be set to ensure that the lifting sealing door 5 is completely closed and well-sealed; and the evacuation time and vacuum level of the vacuum pump 23 can be set to meet the vacuuming requirements of different ton bags.

[0031] After vacuuming is completed, the first cylinder 6 moves in the reverse direction, causing the lifting and sealing door 5 to rise and open. The conveying mechanism 13 then delivers the processed ton bags, completing one work cycle. In this way, the gantry-type vacuum lifting structure efficiently completes the vacuuming process of ton bags through the orderly cooperation of its various components.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
