Description

Technical Field

[0001] This utility model relates to the field of medicine bottle capping, specifically a medicine bottle capping machine for production lines. Background Technology

[0002] A bottle capping machine is a specialized piece of equipment used for pharmaceutical packaging. Its main function is to tightly clamp caps onto the bottle neck to ensure the medicine remains sealed during storage and transportation. This helps prevent external contamination, such as dust and microorganisms, from entering the bottle, and also avoids leakage and spoilage.

[0003] The announcement number is CN221350879U. In the pharmaceutical industry, bottle capping machines play a crucial role as key equipment in the drug packaging process. Their core task is to ensure a tight seal between the bottle and the cap, forming a reliable seal to guarantee the quality and shelf life of the medicine. Existing bottle capping machines typically employ a design where the bottle is placed inside a sleeve, which provides necessary support to maintain a stable vertical position during the capping process. However, there are significant shortcomings in the handling of the bottle cap. Once the bottle is in place, the cap maintains its position solely through minimal friction with the bottle opening. This method of fixation is extremely fragile. In actual working environments, bottle capping machines inevitably experience various vibrations. On one hand, the mechanical components of the equipment itself, such as motors, transmission chains, and cam mechanisms, will inevitably vibrate to varying degrees during continuous operation due to differences in the precision of fit between components, inertia, and uneven power transmission. On the other hand, pharmaceutical workshops are usually not absolutely quiet environments. External factors such as the operation of other equipment, personnel movement, and even the workshop's ventilation system will also bring additional vibration interference to the capping machine. When these vibrations are transmitted to the bottle and cap system, the cap lacks sufficient stable support, and the minimal friction is insufficient to withstand the impact of the vibration. As a result, the cap is prone to displacement, potentially causing radial offset, resulting in inaccurate alignment between the cap and the bottle opening; or axial movement, causing the pressure plate to apply pressure unevenly during capping, increasing the probability of capping failure. Utility Model Content

[0004] The purpose of this invention is to provide a production line medicine bottle capping machine. By using this device, the problems of bottle caps being easily displaced, potentially causing radial offset, resulting in inaccurate alignment between the bottle cap and the mouth of the medicine bottle; and axial movement, which makes it impossible for the pressure plate to apply pressure evenly during capping, increasing the probability of capping failure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0019] Please see Figures 1-3 The present invention provides a technical solution: a medicine bottle capping machine for production line, comprising a base 1, a first support plate 2 fixedly connected to one side above the base 1, a hydraulic cylinder 3 fixedly connected to the first support plate 2, a hydraulic rod 4 fixedly connected to the output end of the hydraulic cylinder 3, a pressure plate 5 fixedly connected to the lower end of the hydraulic rod 4, a sleeve 6 set on the other side above the base 1, the width of the pressure plate 5 being the same as the inner width of the sleeve 6, a pushing mechanism 7 being provided on the inner side of the base 1, and an elastic mechanism 8 being provided on the inner side of the pushing mechanism 7;

[0020] The pushing mechanism 7 includes a push rod 701 fixedly connected to the outside of the hydraulic rod 4. A first hole 702 is provided inside the base 1, and a push plate 703 is provided inside the first hole 702. The central axis of the push plate 703 is on the same straight line as the central axis of the push rod 701, and the central axis of the push plate 703 is perpendicular to the upper plane of the base 1, so that the push rod 701 can drive the push plate 703 to move up and down when it moves up and down. An elastic telescopic rod 704 is fixedly connected to the lower end of the push plate 703. The elastic telescopic rod 704 is fixedly connected to the base 1. A guide hole 705 is provided inside the push plate 703. A second support plate 706 is fixedly connected to the outside of the sleeve 6. The second support plate 706 has a third hole 707 that communicates with the sleeve 6. A first pull rod 708 is provided inside the third hole 707. A guide rod 709 is fixedly connected to the first pull rod 708 inside the guide hole 705. The guide hole 705 has an inclined straight line shape and the guide hole 705 and the guide rod 709 are fitted with a clearance fit. The inner side of the third hole 707 is in contact with the outer side of the first pull rod 708. The first pull rod 708 has a cuboid shape and the central axis of the third hole 707 is parallel to the upper surface of the base 1. This allows the push plate 703 to move the first pull rod 708 inward and outward when it moves up and down.

[0021] The inner side of the first pull rod 708 is provided with a groove 9. The elastic mechanism 8 includes a spring 801 fixedly connected to the inner side of the groove 9. A baffle 802 is fixedly connected to one end of the spring 801 near the central axis of the sleeve 6. A second hole 803 is connected to one end of the groove 9 near the central axis of the sleeve 6. A second pull plate 804 fixedly connected to the baffle 802 is provided inside the second hole 803. A clamping plate 805 is fixedly connected to one end of the second pull plate 804 near the central axis of the sleeve 6. A sealing gasket 806 is provided on the outer side of the clamping plate 805. The outer side of the second pull plate 804 fits against the inner side of the second hole 803. The width of the second hole 803 is smaller than the width of the groove 9. The inner side of the groove 9 fits against the outer side of the baffle 802, so that the baffle 802 can slide inside the groove 9, but will not move out of the inner side of the groove 9.

[0022] When capping medicine bottles, the external device places the medicine bottle and cap inside the sleeve 6. When the external device lowers, it pushes the push plate 703 downwards. Because the guide hole 705 has an inclined straight-line shape and the guide hole 705 and guide rod 709 are in a clearance fit, the downward movement of the guide hole 705 drives the guide rod 709 and the first pull rod 708 outwards. This causes the first pull rod 708 to pull the baffle 802 and the second pull plate 804 outwards, causing the clamping plate 805 to move. When the external device leaves, the elastic telescopic rod 704... The clamping plate 805 is driven to return to the center to clamp and fix the bottle cap. Then, the hydraulic cylinder 3 is activated to drive the hydraulic rod 4 and the pressure plate 5 to move downward to crush the medicine bottle and the bottle cap. At this time, the push rod 701 drives the push plate 703 to move downward, so that the guide hole 705 moves downward and drives the guide rod 709 and the first pull rod 708 to move outward. This causes the first pull rod 708 to pull the baffle 802 and the second pull plate 804 to move outward, which facilitates the pressure plate 5 to crush the medicine bottle. Before the pressure plate 5 crushes the medicine bottle, the bottle cap is clamped to a certain extent, which reduces the probability of crushing failure.

[0023] As the clamping plate 805 and sealing gasket 806 move outward, since the width of the pressure plate 5 is the same as the inner width of the sleeve 6, the pressure plate 5 has already sealed the top of the sleeve 6. The inner space of the sleeve 6 becomes larger, the air pressure decreases, and the air pressure inside the medicine bottle is greater than the space inside the sleeve 6. The air inside the medicine bottle will move outward. The pressure plate 5 continues to move downward to complete the capping. At this time, the air pressure inside the medicine bottle is less than the normal air pressure, and the outer air exerts a certain pressure on the cap, making the cap more difficult to open and improving the sealing performance.
