Description

Technical Field

[0001] The present application relates to the technical field of a cover removal device, and in particular to a cigarette storage box cover suction device. Background Art

[0002] In the tobacco processing industry, box-type tobacco storage is a common method. To ensure tobacco leaf quality and facilitate management and transportation, specialized boxes are often used. A key step in this process is removing the box lid before packing the leaves and replacing it afterward. This operation is primarily accomplished by capping and decapping machines, which utilize four claws to grasp the edges of the box lid to remove and install the lid.

[0003] However, in real-world production environments, due to repeated use and the influence of external factors, many cigarette storage box lids can become deformed or cracked. When this happens, the claws on traditional capping and uncapping machines may not be able to effectively secure the damaged or aged lids, causing failures in the automated opening or closing process. Such failures not only disrupt the normal operation of the production line but may also require manual adjustments or even replacement of the lids, increasing labor intensity and reducing production efficiency.

[0004] Therefore, it is particularly important to develop a lid handling device that can adapt to different degrees of wear. The ideal solution should be able to improve the success rate of lid handling in various conditions while ensuring safety, reduce downtime caused by equipment failures due to lid removal failures, and thus improve the continuity and efficiency of the entire silk-making workshop. Summary of the Invention

[0005] To address the aforementioned issues, the present invention provides a device for sucking up cigarette box lids. This device achieves lid removal through the coordinated movement of a lifting cylinder, an air distributor block on a mounting plate, and a suction cup assembly. The air distributor block divides a single air source into multiple independent branches, each equipped with an independent vacuum generator. This allows compressed air to enter the suction cup assembly, closes a ball valve, and activates a blower to remove dust from the lid. Opening the ball valve releases compressed air, and the suction cup assembly generates negative pressure to suck up the cigarette box lid, completing the suction process. This device significantly improves the success rate of automated equipment in silk-making workshops operating lids in different states, reduces manual intervention, and improves work efficiency while ensuring product quality.

When inhaling, the ball valve 404 is opened, and the gas is discharged from the exhaust port 402. When blowing, the ball valve 404 is closed, and the gas is blown out from the air blowing port 403 and blown to the suction position of the box cover along the first air pipe 8; when the ball valve 404 is closed, the compressed air enters the suction cup assembly 6 from the suction end and is blown from the suction cup assembly 6 to the box cover of the cigarette box; when the ball valve 404 is opened, the compressed air is blown out from the exhaust end, and at the same time, the suction cup assembly 6 generates negative pressure to suck the box cover of the cigarette box.

[0007] Furthermore, the first air pipes 8 are provided with multiple ones, one end of which is connected to the air outlet end of the air distribution block 3 through a quick-plug connector 7, and the other end is connected to the suction cup assembly 6 through a quick-plug connector 7. Vacuum generators 4 are respectively provided on the multiple first air pipes 8 to form multiple groups of independent vacuum branches. When one of the branches leaks and cannot form a vacuum, the other branches continue to suck the box cover.

[0008] Furthermore, one end of the second air pipe 10 is connected to the air inlet end of the air distribution block 3 through a quick-connect connector 7, and the other end is in contact with the air. A solenoid valve 2 is provided on the second air pipe 10 for controlling the air source to enter the air distribution block 3 from the second air pipe 10.

[0009] Furthermore, a through hole is provided in the ball valve 404. When the ball valve 404 is opened, the air inlet 401 and the exhaust port 402 are connected through the through hole, and the gas is discharged from the exhaust port 402 through the through hole. When the ball valve 404 is closed, the passage between the air inlet 401 and the exhaust port 402 is closed to form a closed airway, and the compressed air is blown out from the blowing port 403.

[0010] Furthermore, the suction cup assembly 6 includes an inner tube 601, an outer spiral tube 602, and a suction cup 603; the inner tube 601 is connected to the suction end of the vacuum generator 4; a spring 604 is installed on the inner tube 601, which plays a vibration reduction role in the process of sucking the box cover; the outer spiral tube 602 is installed with two nuts 605, and the height of the suction cup assembly 6 is adjusted by rotating the nuts 605; the suction cup 603 is fixedly installed at the bottom of the inner tube 601 for sucking the box cover.

[0011] Furthermore, the mounting plate 9 is provided with a first threaded hole 901 , a second threaded hole 902 , a third threaded hole 903 , and a through hole 904 .

[0012] Furthermore, the lifting cylinder 1 is fixedly mounted on the mounting plate 9 through the first threaded hole 901. The lifting cylinder 1 moves up and down, driving the mounting plate 9 to move up and down synchronously, so that the suction cup 603 contacts the box cover to realize the cover removal operation.

[0013] Furthermore, the solenoid valve 2 is fixedly mounted on the mounting plate 9 through the second threaded hole 902 , and cooperates with the vacuum generator 4 to control the flow of compressed air.

[0014] Furthermore, the gas distributor block 3 is fixedly mounted on the mounting plate 9 through the third threaded hole 903 ; the suction cup assembly 6 passes through the through hole 904 and is fixedly mounted on the mounting plate 9 through two nuts 605 .

[0015] Furthermore, it also includes a vacuum filter 5, which is arranged between the vacuum generator 4 and the suction cup assembly 6 to filter the dust sucked by the suction cup 603 during the process of removing the box cover.

[0016] Working principle: When the smoke storage box cover suction device is working, the piston rod of the lifting cylinder 1 extends, driving the mounting plate 9 to move downward, and the suction cup assembly 6 descends together with the mounting plate. When it approaches the box cover, the piston rod of the lifting cylinder 1 stops moving downward, and the solenoid valve 2 is opened, starting a short blowing process. The compressed air enters the air distribution block 3 through the solenoid valve 2 and the air pipe. The air distribution block 3 divides the compressed air into multiple independent branches. The vacuum generator 4 on each branch starts to work and closes the ball valve 404 set in the vacuum generator 4. The gas is blown out from the blowing port 403 and blown out along the air pipe to the area between the suction cup 603 and the box cover, blowing the accumulated dust, impurities or other tiny particles away from the area, so that a good sealing effect is formed between the suction cup 603 and the box cover. The piston rod of the lifting cylinder 1 continues to move downward until the suction cup 603 contacts the surface of the box cover, and the compressed air enters the air distributor block 3 through the solenoid valve 2 and the air pipe. The air distributor block 3 divides the compressed air into multiple independent branches, and the vacuum generator 4 on each branch starts to work. The gas is discharged from the exhaust port 402 of the vacuum generator 4. At the same time, negative pressure is generated at the suction end, and the air in the suction cup assembly 6 is drawn away through the air pipe. As the air in the suction cup assembly 6 decreases, an enclosed space is gradually formed between the suction cup 603 and the box cover and a negative pressure difference is generated. At this time, the suction cup is tightly adsorbed on the box cover. When the adsorption force between the suction cup 603 and the box cover reaches a certain value, the piston rod of the lifting cylinder 1 retracts, driving the mounting plate 9 to rise. Due to the firm adsorption between the suction cup 603 and the box cover, the box cover rises together with the mounting plate 9, thereby realizing the cover removal operation. When the box cover is transported to the designated position, the solenoid valve 2 is closed, cutting off the compressed air supply, the vacuum generator 4 stops working, the negative pressure in the suction cup assembly 6 gradually disappears, the lifting cylinder 1 extends again, pushing the mounting plate 9 down, separating the suction cup 603 from the box cover, and completing the entire cover removal process.

[0017] Beneficial effects:

[0018] 1. The utility model divides a single gas source into multiple independent branches through a gas distributor block, and an independent vacuum generator is set in each branch. When one or several branches leak, the other branches can still work normally. The multi-branch design greatly improves the reliability and stability of the device.

[0019] 2. The utility model provides an independent vacuum generator in each branch. The vacuum generator creates negative pressure through the flow of compressed air. In the smoke storage box cover suction device, the generation of this negative pressure enables the suction cup to be tightly adsorbed on the box cover, thereby achieving a stable grasping and carrying process.

[0020] 3. Before the suction operation is officially carried out, the vacuum generator of the utility model will temporarily turn off the suction function and turn on the blowing mode, using compressed air to remove dust and other tiny particles on the contact surface between the suction cup and the box cover, avoiding the influence of dust and other impurities on the adsorption effect of the suction cup, and significantly improving the sealing performance between the suction cup and the box cover.

[0021] 4. The height of the suction cup assembly of the utility model is adjusted by the nut on the outer screw tube to adapt to cigarette storage boxes of different specifications and box covers that may have slight deformation, making the device highly adaptable and universal.

[0022] 5. The utility model provides a vacuum filter between the vacuum generator and the suction cup assembly to filter out dust and impurities sucked in during the suction process, which helps to extend the service life of key components and reduce maintenance costs.

[0023] 6. The entire device of this utility model has a simple structure, is easy to operate and maintain. All components are fixed and connected by quick-connect connectors or nuts, and can be disassembled, assembled, and replaced without complex tools. In addition, due to the use of a grouped gas path design, even if a branch fails, it will not affect the operation of the entire device, and the faulty branch can be repaired and replaced easily.

The air inlet end of the air distribution block 3 is connected to the air source through the second air pipe 10, and the air outlet end and the suction cup assembly 6 are connected through the first air pipe 8 to form a grouped air path, and each group of air paths independently completes the work of sucking the box cover; a vacuum generator 4 is provided on the air pipe, the air inlet end of the vacuum generator 4 is connected to the air distribution block 3, the exhaust end is connected to the outside atmosphere, and the suction end is connected to the suction cup assembly 6; the vacuum generator 4 is provided with an air inlet 401, an exhaust port 402 and an air blowing port 403; a ball valve 404 is provided inside the exhaust port 402. When inhaling, the ball valve 404 is opened and the gas is discharged from the exhaust port 402. When blowing, the ball valve 404 is closed and the gas is blown out from the blowing port 403 and blown to the box cover suction position along the first air pipe 8; when the ball valve 404 is closed, the compressed air enters the suction cup assembly 6 from the suction end and blows from the suction cup assembly 6 to the cigarette box cover; when the ball valve 404 is opened, the compressed air is blown out at the exhaust end, and at the same time the suction cup assembly 6 generates a negative pressure to suck the cigarette box cover.

[0037] like Figure 1The lifting cylinder 1 shown is fixedly mounted on the mounting plate 9 through the first threaded hole 901. The lifting cylinder 1 moves up and down, driving the mounting plate 9 to move up and down synchronously, so that the suction cup 603 contacts the box cover and realizes the cover removal operation. The solenoid valve 2 is fixedly mounted on the mounting plate 9 through the second threaded hole 902, and cooperates with the vacuum generator 4 to control the flow of compressed air. The air distributor 3 is fixedly mounted on the mounting plate 9 through the third threaded hole 903; the suction cup assembly 6 passes through the through hole 904 and is fixedly mounted on the mounting plate 9 through two nuts 605. There are 8 first air pipes 8, one end of which is connected to the air outlet end of the air distributor 3 through a quick-connect connector 7, and the other end is connected to the suction cup assembly 6 through a quick-connect connector 7. The 8 first air pipes 8 are respectively provided with a vacuum generator 4 to form multiple groups of independent vacuum branches. When one of the branches leaks and cannot form a vacuum, the other branches continue to suck the box cover. One end of the second air pipe 10 is connected to the air inlet of the air distributor 3 via a quick-connect connector 7, while the other end is exposed to the air. A solenoid valve 2 is provided on the second air pipe 10 to control the flow of air from the second air pipe 10 into the air distributor 3. A vacuum filter 5, located between the vacuum generator 4 and the suction cup assembly 6, filters dust absorbed by the suction cup 603 during the removal of the box cover.

[0038] like Figure 2 、 3 As shown, a ball valve 404 is provided inside the exhaust port 402 of the vacuum generator 4, and a through hole is provided inside the ball valve 404. When the ball valve 404 is opened, the air inlet 401 and the exhaust port 402 are connected through the through hole, and the gas is discharged from the exhaust port 402 through the through hole. When the ball valve 404 is closed, the channel between the air inlet 401 and the exhaust port 402 is closed, forming a closed airway, and the compressed air is blown out from the blowing port 403.

[0039] like Figure 4 、 5 The inner tube 601 of the suction cup assembly 6 shown is connected to the suction end of the vacuum generator 4; a spring 604 is installed on the inner tube 601, which plays a vibration reduction role during the process of sucking the box cover 13; the outer screw tube 602 is installed with two nuts 605, and the height of the suction cup assembly 6 is adjusted by rotating the nuts 605; the suction cup 603 is fixedly installed at the bottom of the inner tube 601 for sucking the box cover 13.

[0040] like Figure 9As shown, when in use, the lifting cylinder 1 is turned on, the piston rod of the lifting cylinder 1 is extended, and the mounting plate 9 is driven to move downward. The suction cup assembly 6 drops together with the mounting plate 9. When it approaches the box cover 13, the piston rod of the lifting cylinder 1 stops moving downward, and the solenoid valve 2 is opened to start a short blowing process. The compressed air enters the air distribution block 3 through the solenoid valve 2 and the second air pipe 10. The air distribution block 3 divides the compressed air into multiple independent branches. The vacuum generator 4 on each branch starts to work, and the ball valve 404 set in the vacuum generator 4 is closed. The gas is blown out from the blowing port 403, and the compressed air is blown out through the first air pipe 8 to the area between the suction cup 603 and the box cover 13, blowing the accumulated dust, impurities or other tiny particles away from the area, so that a good sealing effect is formed between the suction cup 603 and the box cover 13.

The vacuum generator 4 discharges the air from its exhaust port 402 and generates negative pressure at the suction end. The air in the suction cup assembly 6 is drawn away through the first air pipe 8. As the air in the suction cup assembly 6 decreases, a closed space is gradually formed between the suction cup 603 and the box cover 13 and a negative pressure difference is generated. At this time, the suction cup 6 03 is tightly adsorbed on the box cover 13. When the adsorption force between the suction cup 603 and the box cover 13 reaches a certain value, the piston rod of the lifting cylinder 1 retracts, driving the mounting plate 9 to rise, and the suction cup assembly 6 rises synchronously. Due to the firm adsorption between the suction cup 603 and the box cover 13, the box cover 13 rises together with the suction cup assembly 6 and the mounting plate 9, and the box cover 13 is sucked out. When the box cover 13 is transported to the designated position, the solenoid valve 2 is closed, cutting off the compressed air supply, the vacuum generator 4 stops working, the negative pressure in the suction cup assembly 6 gradually disappears, and the lifting cylinder 1 extends again, pushing the mounting plate 9 down, separating the suction cup 603 from the box cover 13, and completing the entire cover removal process.
