Description

Technical Field

[0001] The utility model relates to the technical field of plastic barrel upper covers, in particular to a mechanism for automatically upper covers of plastic barrels. Background Art

[0002] A plastic bucket is a container made primarily of plastic through processes like injection molding and blow molding. It's typically cylindrical in shape, with an open top for filling. Some buckets come with a lid for sealing. Plastic buckets are made from a variety of materials, including polyethylene (PE) and polypropylene (PP). These materials give them distinct performance characteristics to suit a variety of applications.

[0003] When processing plastic barrels, it is necessary to perform a lid operation to effectively seal the plastic barrel and prevent the contents from leaking. When lidding, the plastic barrel is first placed on the corresponding conveyor roller for conveying. When it is conveyed to a certain position, the lid is closed by a vacuum suction cup.

[0004] The plastic barrel has corresponding solids or liquids rotating inside. When the plastic barrel filled with liquid is transported by conveyor rollers, the liquid in the barrel will shake with the movement of the barrel. This shaking will generate an unbalanced force, causing the center of gravity of the plastic barrel to change, thereby making the plastic barrel at risk of deviation on the conveyor roller. When the deviation occurs, there will be a corresponding deviation between the top of the plastic barrel and the cover, which will affect the cover operation. Therefore, a mechanism for automatic cover application in plastic barrels is proposed to solve the above problem. Utility Model Content

The bottom end of the support column 6 is fixedly connected to the bottom plate 9, and the inner wall of the bottom plate 9 is threadedly connected to the threaded rod 15. The setting of the threaded rod 15 can thereby achieve the adjustment purpose. The outer wall of the bottom plate 9 is fixedly connected to the support rod 16, and the support rod 16 plays a guiding role. The side of the support rod 16 away from the support column 6 is fixedly connected to the clamping block 17. The movement trajectories of the two are consistent. The outer wall of the clamping block 17 is detachably installed with a guide plate 7, and the inner wall of the guide plate 7 is provided with a disassembly component. When the guide plate 7 is damaged, it can be quickly disassembled by disassembling the component.

[0034] Reference Figure 1-Figure 3 The front end of the support frame 3 is fixedly connected with a guide rod 4, and the inner wall of the movable plate 5 is slidably connected to the outer arc surface of the guide rod 4. The guide rod 4 can be provided with multiple groups, and the multiple groups of guide rods 4 can play a supporting and guiding role for the movable plate 5, so that it can only move vertically. The left and right ends of the movable plate 5 are provided with guide grooves, and the front end of the movable seat 12 contacts the inner wall of the guide groove. The upper part of the guide groove is vertical, and the lower part is inclined and inclined toward the outer end. The rear end of the connecting rod 11 is fixedly connected to the front end of the positioning block 8, and the movement of the positioning block 8 drives the connecting rod 11 to move. The threaded rod 15 is rotated and connected to the inner wall of the clamping block 17 on the side close to the support column 6. The rotation setting avoids movement interference. The support rod 16 is telescopic as a whole. The support rod 16 is a telescopic rod. The overall length can be adjusted and can guide the clamping block 17. The front end opening of the guide plate 7 is larger, and the larger opening can better center the plastic barrel.

[0035] Reference Figure 2-Figure 4The disassembly assembly includes a connecting spring 20, one end of the connecting spring 20 is fixedly connected to the inner wall of the guide plate 7, and the other end of the connecting spring 20 is fixedly connected to the limit seat 19. The outer wall of the limit seat 19 is slidably connected to the inner wall of the guide plate 7.

The top end of the limit seat 19 is fixedly connected to the fixing column 18, and the setting of the fixing column 18 drives multiple groups of limit seats 19 to move synchronously.

[0037] Working principle: When the relevant personnel need to cover the plastic barrel, they first place the plastic barrel on the conveyor roller, and then start the conveyor roller to move the plastic barrel. When the plastic barrel moves to a certain position, the cylinder 10 works and drives the positioning block 8 to move downward. Due to the downward movement of the positioning block 8, the movable plate 5 will also move downward under the guidance of the guide rod 4, thereby causing the guide groove to move downward. At this time, the front end of the moving seat 12 is restricted by the oblique groove below the guide groove, which will drive the guide plate 7 to move closer to the middle, thereby centering the plastic barrel, and when the plastic barrel moves to the top and meets the vacuum suction When the bottom end of the disc 2 corresponds, the vacuum suction cup 2 and its positioning block 8 continue to move downward to press the cover plate and the top of the plastic barrel to perform the cover operation, and the movable plate 5 moves downward at this time, and the movable seat 12 is limited by the vertical groove above the guide groove and will not move horizontally, so as to center the plastic barrel and avoid the problem of misalignment between the two due to offset when the plastic barrel is covered. When the overall model of the plastic barrel changes, the threaded rod 15 can be rotated so that the threaded rod 15 drives the clamping block 17 to move outward, thereby making the guide plate 7 move inward to adapt to different models of plastic barrels, making the overall applicability stronger.

[0038] When the guide plate 7 needs to be replaced, the two sets of limit seats 19 are moved upward by the fixing column 18. When the two sets of limit seats 19 move upward, they will squeeze the connecting spring 20, thereby releasing the limit of the limit seat 19 on the clamping block 17, and then the guide plate 7 can be moved horizontally and removed and replaced. The new guide plate 7 is then plugged into the clamping block 17, so that the outer wall of the clamping block 17 contacts the inclined surface of the clamping block 17, so that the clamping block 17 is completely plugged into the guide plate 7. At this time, due to the elasticity of the connecting spring 20, the limit seat 19 is reset and then plugged into the clamping block 17 to complete the fixation. The operation is simple and convenient.
