Description

Technical Field

[0001] This utility model relates to the field of cylindrical wine box processing technology, specifically to a cylindrical wine box top cover device. Background Technology

[0002] Cylindrical wine boxes are the mainstream packaging for mid-to-high-end wines. The assembly of the top cap and the body of the bottle is a core process that directly affects product quality and production capacity. Currently, most companies still rely on manual labor to complete this process. Workers need to manually remove the cap, move the bottle, and position it for assembly. This has significant drawbacks: repetitive labor can easily lead to fatigue, resulting in low efficiency and a lower pass rate due to errors; manual contact can easily scratch the workpiece, increasing wear and tear; and changeovers require changing fixtures or complex adjustments, taking 1-2 hours, resulting in insufficient production line flexibility.

[0003] A search revealed an automatic wine box lid installation device with patent number CN202322435645.5, which uses an adjustable placement slot, infrared sensors, and eccentric wheels to achieve box positioning and precision adjustment. However, this technology has significant limitations: it only covers the assembly and positioning stage; material loading and unloading still require manual labor, failing to achieve full automation; it lacks an adsorption and unloading structure and relies on manual adjustment of the positioning slot, making it unable to quickly adapt to workpieces of different diameters; and it lacks coordinated control between the motor and actuators, resulting in insufficient stability.

[0004] Therefore, the cylindrical wine box manufacturing industry urgently needs a fully automated assembly solution that can be quickly adapted to different specifications. This solution can address the efficiency, cost, and stability issues of manual labor and existing equipment through multi-mechanism collaboration and flexible adjustment. Utility Model Content

A connecting plate 8 is rotatably connected to the first connecting block 7, and a second connecting block 9 is rotatably connected to the other end of the connecting plate 8. A first electric push rod 10 is installed at the bottom of the working disc 4. The output end of the electric push rod 10 is connected to an adjustment block 11, and four second connecting blocks 9 are fixedly connected to the adjustment block 11, realizing the automatic adjustment of the positioning mechanism. When the first electric push rod 10 drives the adjustment block 11 to move, it can synchronously drive the four sliding columns 5 to slide along the slide groove through the connecting plate 8, thereby making the limit column 6 open and close synchronously. It can quickly adapt to the upper bottom cover of different diameters and improve the positioning efficiency. The sliding cooperation between the sliding column 5 and the slide groove ensures the stability of the movement of the limit column 6. The support of multiple connecting rods 3 on the working plate 4 enhances the structural rigidity of the positioning mechanism, ensuring that the bottom cover will not shift during the positioning process and improving the accuracy of the upper bottom cover.

[0029] Reference Figure 1 , Figure 3 and Figure 4The feeding mechanism includes a support base 12 and an adjusting plate 13. The support base 12 is fixedly connected to the mounting base 1. The mounting plate 14 is fixedly connected to the support base 12. A bottom plate 15 and a top plate 16 are fixedly connected to the mounting plate 14. The adjusting plate 13 is slidably engaged with the mounting plate 14. A first motor 17 is mounted on the top of the top plate 16. The output end of the first motor 17 passes through the top plate 16 and is connected to a screw 18. The bottom end of the screw 18 passes through the adjusting plate 13 and is rotatably connected to the bottom plate 15. The screw 18 is threadedly engaged with the adjusting plate 13. A support plate 19 is fixedly connected to the adjusting plate 13. The support plate 19 has multiple openings for... The first motor 17 drives the screw 18 to rotate in the avoidance groove that avoids the limiting post 6. The screw 18 and the adjusting plate 13 are threaded together to drive the adjusting plate 13 to move up and down steadily along the mounting plate 14, realizing automatic feeding of the upper and lower covers on the pallet 19 without frequent manual handling, thus reducing labor costs. The design of the avoidance groove allows the pallet 19 to avoid the limiting post 6 during the lifting process, avoiding interference between structures and ensuring the coordinated work of the feeding mechanism and the positioning mechanism. The mounting plate 14, the bottom plate 15 and the top plate 16 form a stable frame structure, providing reliable support for the lifting of the adjusting plate 13 and improving the stability of the feeding process.

[0030] Reference Figure 1 , Figure 3 and Figure 4 The material handling mechanism is connected to the top plate 16 and the mounting plate 14. The material handling mechanism includes a mounting frame 20, which is fixedly connected to the mounting plate 14. Two support rods 21 are fixedly connected to the top of both the top plate 16 and the mounting frame 20. A fixed plate 22 is fixedly connected to the top of each of the four support rods 21. A second motor 23 is mounted on the top of the mounting frame 20. The output end of the second motor 23 passes through the fixed plate 22 and is connected to a connecting frame 24. Second electric push rods 25 are mounted on both sides of the top of the connecting frame 24. The output end of the second electric push rod 25 passes through the connecting plate 24. The connecting frame 24 is connected to an electric suction cup 26. The second motor 23 can drive the connecting frame 24 to rotate around the fixed plate 22, which works with the electric suction cup 26 to pick up and put down materials, making it easy to accurately move the top cover to the wine box. The second electric push rod 25 can drive the electric suction cup 26 to move up and down, adapting to the material picking and putting needs at different heights. The electric suction cup 26 uses negative pressure to adsorb the top cover, which is stable and will not damage the cover.

The two ends of the guide rod 29 are fixedly connected to the top plate 16 and the bottom plate 15, respectively. The cooperation between the guide rod 29 and the guide openings provides dual guidance for the lifting and lowering of the adjusting plate 13, effectively preventing the adjusting plate 13 from rotating or tilting under the drive of the screw 18, ensuring that the support plate 19 always remains horizontal, and ensuring that the bottom cover will not tip over during the feeding process. The guide structure can also disperse the radial force on the adjusting plate 13, avoid the screw 18 from wearing due to excessive force on one side, and improve the service life and operational stability of the feeding mechanism.

[0034] Reference Figure 1 and Figure 4 The mounting base 1 has multiple through mounting holes 30, which provide a convenient mounting interface for fixing the entire device.

[0036] Reference Figures 1-4The cylindrical wine box top cover device includes a mounting base 1 with multiple through mounting holes 30. These holes provide a convenient mounting interface for securing the entire device, allowing for stable fixation to a workbench or production line using bolts or other fasteners. This prevents displacement due to vibration during operation and ensures the accuracy of coordinated operation of all mechanisms. The device also includes a positioning mechanism, comprising a pad 2 fixedly connected to the mounting base 1. Multiple connecting rods 3 are fixedly connected to the top of the pad 2, and a working disc 4 is fixedly connected to the top of each connecting rod 3. The working disc 4 has four sliding grooves, within which sliding columns 5 slide. The sliding fit between the sliding columns 5 and the grooves ensures the stability of the movement of the limiting columns 6.

Block 7, a connecting plate 8 is rotatably connected to the first connecting block 7, and a second connecting block 9 is rotatably connected to the other end of the connecting plate 8. A first electric push rod 10 is installed at the bottom end of the working plate 4. An adjusting block 11 is connected to the output end of the first electric push rod 10.

When the first electric push rod 10 drives the adjusting block 11 to move, it can synchronously drive the four sliding columns 5 to slide along the slide groove through the connecting plate 8, thereby making the limiting column 6 open and close synchronously. It can quickly adapt to the top cover of different diameters and improve the positioning efficiency. Multiple arc-shaped openings are provided on the adjusting block 11. An arc-shaped plate 28 is slidably connected in the arc-shaped opening. The two ends of the arc-shaped plate 28 are fixedly connected to the working plate 4 and the pad plate 2, respectively. The sliding cooperation between the arc-shaped plate 28 and the arc-shaped opening provides guidance and limiting function for the movement of the adjusting block 11, ensuring that the adjusting block 11 moves along a fixed trajectory under the drive of the first electric push rod 10, avoiding the adjustment block 11 from deflecting, thereby ensuring the consistency of the synchronous movement of the four sliding columns 5.

[0037] It should also be noted that the feeding mechanism includes a support base 12 and an adjusting plate 13. The support base 12 is fixedly connected to the mounting base 1, and a mounting plate 14 is fixedly connected to the support base 12. A bottom plate 15 and a top plate 16 are fixedly connected to the mounting plate 14. The adjusting plate 13 is slidably engaged with the mounting plate 14.

The bottom end of the screw 18 passes through the adjusting plate 13 and is rotatably connected to the bottom plate 15. The screw 18 is threadedly engaged with the adjusting plate 13. A support plate 19 is fixedly connected to the adjusting plate 13. The first motor 17 drives the screw 18 to rotate. The threaded engagement between the screw 18 and the adjusting plate 13 drives the adjusting plate 13 to move stably up and down along the mounting plate 14, realizing automatic feeding of the top and bottom covers onto the support plate 19. This eliminates the need for frequent manual handling and reduces labor costs. To reduce costs, the pallet 19 has multiple clearance slots for avoiding the limit post 6. The clearance slots are designed so that the pallet 19 can avoid the limit post 6 during lifting and lowering, avoiding interference between structures and ensuring the coordinated work of the feeding mechanism and the positioning mechanism. The adjusting plate 13 has two guide openings, and guide rods 29 are slidably connected in the guide openings. The two ends of the guide rods 29 are fixedly connected to the top plate 16 and the bottom plate 15, respectively. The cooperation between the guide rods 29 and the guide openings provides dual guidance for the lifting and lowering of the adjusting plate 13, effectively preventing the adjusting plate 13 from rotating or tilting under the drive of the screw 18, ensuring that the pallet 19 always remains in a horizontal state, and ensuring that the bottom cover will not tip over during the feeding process. The guide structure can also disperse the radial force on the adjusting plate 13, preventing the screw 18 from wearing due to excessive force on one side, and improving the service life and operational stability of the feeding mechanism.

Second electric push rods 25 are installed on both sides of the top of the connecting frame 24. The output end of the second electric push rods 25 passes through the connecting frame 24 and is connected to an electric suction cup 26. The second motor 23 can drive the connecting frame 24 to rotate around the fixed plate 22, which, together with the electric suction cup 26, realizes the picking and placing of materials, making it easy to accurately move the top cover. The material is delivered to the wine box. The second electric push rod 25 can drive the electric suction cup 26 to move up and down, adapting to different height requirements for picking up and placing materials. The electric suction cup 26 uses negative pressure to adsorb the bottom cover, ensuring stable gripping without damaging the cover. A guide ring 27 is fixedly connected to the top of the fixed plate 22, and a guide groove that cooperates with the guide ring 27 is opened at the bottom of the connecting frame 24. The cooperation between the guide ring 27 and the guide groove provides precise guidance for the rotation of the connecting frame 24, effectively limiting the radial offset during the rotation of the connecting frame 24, and preventing the electric suction cup 26 from shifting due to shaking of the connecting frame 24, further improving the positional accuracy of picking up and placing materials. At the same time, the guide structure can also share the force of the connecting frame 24, reduce the load on the output end of the second motor 23, and extend the service life of the motor.

[0039] In summary, the working principle and process of the cylindrical wine box top cover device are as follows: First, the device is fixed to the production line workbench or designated position using bolts through the mounting holes 30 of the mounting base 1. Based on the diameter of the top cover to be processed, the first electric push rod 10 is activated, driving the sliding column 5 to slide along the slide groove via the adjusting block 11 and connecting plate 8. The opening and closing range of the four limit posts 6 is adjusted to match the bottom cover size. Then, the top covers to be processed are neatly stacked on the support plate 19. The first motor 17 is activated, driving the screw 18 to rotate and drive the adjusting plate 13. As the upper plate 19 rises, it simultaneously transports the top bottom cover to the material picking position. Then, the second motor 23 is started, which drives the connecting frame 24 to rotate, causing the electric suction cup 26 to move above the plate 19. The second electric push rod 25 extends, driving the electric suction cup 26 to descend and adhere to the top bottom cover. After the second electric push rod 25 retracts, the second motor 23 rotates again to move the top bottom cover above the cylindrical wine box. The second electric push rod 25 extends, driving the electric suction cup 26 to descend, allowing the top bottom cover to cooperate with the subsequent wine box lid assembly process to complete the assembly.
