Technical Field

[0001] This utility model relates to the field of packaging, and in particular to a dual-station automatic capping and screwing device for round bottles. Background Technology

[0002] In the modern packaging industry, the capping process is a crucial step in ensuring the product's airtightness and appearance integrity. Manual capping is inefficient and prone to uneven tightening or loosening, affecting product quality and packaging consistency. To improve production efficiency and packaging precision, automated equipment has gradually become the industry mainstream. Among them, automatic capping machines, with their high efficiency, precision, and stability, are widely used in the food, beverage, pharmaceutical, and daily chemical industries, effectively improving packaging efficiency and ensuring product quality.

[0003] Packaging production faces multiple efficiency and quality bottlenecks. Manual capping is inefficient and labor-intensive, and employee fatigue leads to poor operational consistency. Torque control is unstable, and bottle caps that are too loose can leak or too tight can break, increasing rework costs and hindering the company's large-scale production and market competitiveness. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a dual-station automatic capping and screwing device for round bottles, which aims to improve the problems of wasted labor costs and unstable torque.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3 An embodiment of this utility model provides a dual-station automatic capping and screwing device for round bottles, comprising a workbench 1, a fixed plate 2 fixedly connected to the top of the workbench 1, multiple movable plates 3 slidably connected to the inner wall of the fixed plate 2, a rotating rod 4 fixedly connected to the inner wall of the movable plate 3, a conveyor belt 6 sleeved on the outer wall of the workbench 1, multiple bottle caps 5 slidably connected to the outer wall of the conveyor belt 6, multiple transport boxes 7 fixedly connected to the outer wall of the conveyor belt 6, bottles 8 slidably connected to the inner wall of the multiple transport boxes 7, a fixed block 9 fixedly connected to the bottom of the workbench 1, multiple limiting plates 10 fixedly connected to the top of the workbench 1, a first motor 11 installed inside the fixed block 9, multiple first gears 12 and second gears 13 arranged inside the fixed block 9, a rotating shaft 14 fixedly connected to the inner wall of each of the multiple first gears 12 and second gears 13, a rotating block 15 fixedly connected to the outer wall of each of the multiple rotating shafts 14, and a pressing component arranged on the outer wall of the workbench 1.

[0026] Specifically, the bottle 8 is first placed in the transport box 7 of the conveyor belt 6. The transport box 7 limits the movement of the bottle 8 through nesting, preventing the bottle from shaking during transport and the simultaneous movement of the bottle 8 when the cap is screwed on. The conveyor belt 6 drives the transport box 7 and the bottle 8 along the track. When the bottle 8 touches the movable plate 3 that is slidably connected to the inner wall of the fixed plate 2, the bottom movable plate 3 is pushed and moves around the rotating rod 4, which in turn moves the top movable plate 3 synchronously. The top movable plate precisely controls the bottle cap 5 in the cap storage area to fall off once. When no bottle 8 passes by, the movable plate 3 remains stationary. State; After the bottle body 8 is separated from the movable plate 3, it continues to move forward to the capping station constrained by the limiting plate 10. The first motor 11 in the fixed block 9 drives the first gear 12 at the output end to rotate forward. Through gear meshing, a forward-reverse-forward-reverse transmission chain is formed: the second gear 13 on the left is driven to reverse, and the first gear 12 on the right is synchronously reversed, which in turn drives the subsequent gear set to move together, so that the rotating shaft 14 on the inner wall of each gear drives the top rotating block 15 to rotate. The rotating block 15 on the left side of the bottle body 8 rotates forward and the rotating block 15 on the right side rotates backward, applying a reverse tightening force to the bottle cap from both sides.

[0027] Reference Figure 6 The pressing component includes a limiting block 16, which is fixedly connected to the outer wall of the worktable 1. A second motor 17 is installed on the inner wall of the limiting block 16. A cam 18 is rotatably connected inside the limiting block 16. A slide rod 19 is slidably connected inside the limiting block 16. A spring 20 is provided on the inner wall of the limiting block 16. A pressure plate 21 is fixedly connected to the bottom of the slide rod 19.

[0028] Specifically, when the bottle 8 enters the station of the limiting block 16, the second motor 17 inside the limiting block 16 drives the cam 18 to rotate. The contour surface of the cam 18 presses the slide bar 19, causing the slide bar 19 to slide down along the inner wall of the limiting block 16, which drives the bottom pressure plate 21 to press down synchronously. This causes the pressure plate 21 to act on the top of the bottle cap 5. The elastic restoring force of the spring 20 pulls the slide bar 19 to move up and reset, causing the pressure plate 21 to disengage from the bottle cap, thus avoiding deformation caused by continuous pressure.

[0029] Reference Figure 4 The rotating rod 4 is rotatably connected inside the fixed plate 2.

[0030] Specifically, the fixed plate 2 limits the rotation rod 4, so that the rotation rod 4 and the movable plate 3 will not leave the working range.

[0031] Reference Figure 1 Multiple rotating blocks 15 and rotating shafts 14 are rotatably connected to the inner walls of multiple limiting plates 10.

[0032] Specifically, the limiting plate 10 further limits the rotating block 15 and the rotating shaft 14, so that they can be precisely aligned with the bottle cap 5 at the top of the bottle body 8.

[0033] Reference Figure 1 , Figure 2 , Figure 5 The conveyor belt 6 is mounted on the inner wall of the fixed plate 2, and multiple bottle caps 5 are slidably connected to the outer wall of the movable plate 3, and multiple bottles 8 are slidably connected to the outer wall of the movable plate 3.

[0034] Specifically, the conveyor belt 6 inside the fixed plate 2 transports the bottle cap 5 forward, and cooperates with the movable plate 3 to land on top of the bottle body 8.

[0035] Reference Figure 3 One of the first gears 12 is fixedly connected to the output end of the first motor 11, and the tooth ends of multiple second gears 13 are all meshed with the tooth ends of the first gear 12. The multiple first gears 12 are meshed with each other, and the multiple second gears 13 are meshed with each other.

[0036] Specifically, the forward and reverse rotation of the gear set works together to make the left rotating block 15 and the right rotating block 15 rotate in opposite directions, thus tightening the bottle cap 5.

[0037] Reference Figure 6 Cam 18 is fixedly connected to the output end of the second motor 17.

[0038] Specifically, the second motor 17 drives the cam 18 to rotate.

[0039] Reference Figure 6 The slide rod 19 is slidably connected to the outer wall of the cam 18, and the spring 20 is slidably connected to the outer wall of the slide rod 19.

[0040] Specifically, the cam 18 causes the slide bar 19 to move periodically, pressing down the pressure plate 21 and then being reset by the spring 20 for the next operation.

[0041] Working principle: First, the bottle 8 is placed in the transport box 7 installed on the conveyor belt 6 on the outer wall of the workbench 1 to fix the bottle. Then, the conveyor belt 6 drives the transport box 7 and the bottle 8 to move along the movement trajectory of the conveyor belt 6. When the bottle 8 touches the sliding movable plate 3 on the inner wall of the fixed plate 2, the lower movable plate 3 will drive the upper movable plate 3 to move around the rotating rod 4 at the same time. The bottom movable plate 3 is pushed by the bottle 8, and the upper movable plate 3 will cause one of the bottle caps 5 to fall off and land on top of the bottle 8. When the bottle 8 is not connected to the movable plate 3, the top bottle cap 5 will not fall off. The bottle 8 continues to move forward until it is within the range of the limit plate 10. The first motor 11 inside the bottom fixing block 9 drives a first gear 12 at its output end to rotate forward. This first gear 12 drives a second gear 13 on the left to rotate in reverse and another first gear 12 on the right to rotate in reverse. This second gear 13 drives another second gear 13 at its tooth end to rotate forward. This first gear 12 drives another second gear 13 to rotate forward, and the other second gear 13 drives the second gear 13 at its tooth end to rotate in reverse. Each gear has a rotating shaft 14 fixed on its inner wall, and a rotating block 15 is fixed on the top of the rotating shaft 14. This forms a situation where the rotating block 15 on the left side of the bottle body 8 rotates forward and the rotating block 15 on the right side rotates in reverse, so as to tighten the bottle cap 5.

[0042] After the bottle cap 5 falls on top of the bottle body 8, it may be tilted due to the threads. When the bottle body 8 enters the range of the limiting block 16, the second motor 17 inside the limiting block 16 drives the cam 18 to rotate. The cam 18 causes the slide rod 19 to move up and down. The slide rod 19 drives the pressure plate 21 fixed at its bottom to move so that the bottle cap 5 fits against the threads of the bottle body 8. The spring 20 is set on the outer wall of the slide rod 19 and its bottom is connected to the limiting block 16 so that the slide rod 19 will be reset after it moves down.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
