Description

Technical Field

[0001] This utility model relates to the field of automatic lid opening technology, and in particular to an automatic container lid opening device. Background Technology

[0002] The current method of opening vials is manual. During the manual opening of the aluminum caps of vials containing radioactive raw materials, personnel come into direct contact with the radioactive liquid, which affects the safety of the staff. Moreover, for nuclear medicine production line equipment, an automatic vial cap opening device is required throughout the entire production process, and the existing technology cannot meet the customer's needs. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic container opening device, which solves the problem of how to achieve automatic container opening.

[0004] This utility model is implemented as follows: an automatic container opening device includes a drive mechanism, a connecting shaft, and an opening structure connected in sequence. The opening structure is connected to a movable shaft, and a fixed seat for limiting the descent height of the opening structure is sleeved on the outer periphery of the movable shaft. The opening structure includes an opening claw and a guide limiting member. The guide limiting member contacts the inner wall of the opening claw. The bottom of the guide limiting member has a protrusion that can contact the container stopper. The guide limiting member is connected to the drive mechanism through the connecting shaft so that the protrusion contacts the container stopper and the opening claw opens the container stopper along the outer periphery of the container stopper.

[0005] The drive mechanism moves the connecting shaft and the cap-opening structure. As the cap-opening structure moves downwards, it drives the movable shaft downwards as well. When the movable shaft reaches the limit position of the fixed seat, the cap-opening structure is positioned on the outer circumference of the container cap, and the protrusion contacts the upper surface of the container stopper. The drive mechanism then continues to move the connecting shaft and the guide limiter in the cap-opening structure downwards, causing the cap-opening claws to close and contact the container cap. This causes the container cap to deform and expand under pressure, completing the cap-opening action. This invention avoids the need for manual opening of aluminum caps on vials containing radioactive raw materials, preventing direct contact between personnel and radioactive solutions. It can also be integrated into the customer's entire production process to achieve fully automated production and meet customer process requirements.

[0006] A further technical solution of this utility model is: it also includes a mounting base, the driving mechanism is placed above the mounting base, the fixed base, the movable shaft and the connecting shaft are placed below the mounting base and are sequentially sleeved from the outside to the inside, and a vertical guide component is provided between the output end of the driving mechanism and the connecting shaft, and the guide component abuts against the output end of the driving mechanism.

[0007] The drive mechanism moves the opening structure and the movable shaft downwards via the connecting shaft. During its downward movement, the movable shaft stops due to the constraint of the fixed seat. At this point, the opening structure has moved to the outer circumference of the container lid. The drive mechanism continues to transmit force to the opening structure, causing it to open the container lid, thus completing the automatic opening of the container. Considering the distance between the opening device and the container, the output of the drive mechanism needs to transmit force through the connecting shaft. This invention provides a guide assembly between the connecting shaft and the drive mechanism. The guide shaft in the guide assembly and the output of the drive mechanism use a contacting method to transmit force, facilitating the connection between the drive mechanism and the opening assembly on the mounting base. This allows for the overall installation of the opening assembly, making it convenient and quick. A fixed bushing is fitted outside the guide shaft to ensure that the guide shaft drives the opening structure vertically, preventing deviation and ensuring the opening structure accurately moves to the opening position. After opening, the drive mechanism retracts, and the opening assembly is reset via a reset component, returning the opening device to its initial state.

[0008] A further technical solution of this utility model is: the bushing is placed at the end of the movable shaft and the movable shaft is movably connected to the bushing.

[0009] The vertical guide assembly and the connecting shaft work together to transmit the force of the drive mechanism to the opening structure. Placing the bushing in the vertical guide assembly at the end of the movable shaft can reduce space occupation and further restrict the direction of movement of the movable shaft to prevent deviation. In order to avoid interference between the movable shaft and the bushing, the movable shaft can move up and down along the bushing.

[0010] A further technical solution of this utility model is: the upper end of the movable shaft is provided with a limiting shoulder, the middle of the inner side of the fixed seat is provided with a limiting ring that cooperates with the limiting shoulder, the lower inner side of the fixed seat is provided with a mounting ring, and the reset member is placed between the movable shaft and the mounting ring.

[0011] During the downward movement of the movable shaft, the limiting shoulder contacts the limiting ring, and the limiting ring restricts the movement of the movable shaft. At this time, the opening structure moves to the outer periphery of the container lid, and the drive mechanism continues to move to drive the opening structure to open the container lid. The bottom of the fixed seat is provided with a mounting ring. The opening assembly can be reset by the reset component between the mounting ring and the movable shaft.

[0012] A further technical solution of this utility model is: an elastic element is provided between the opening claws.

[0013] Avoid damaging the container during the opening process.

[0014] A further technical solution of this utility model is: the opening structure further includes a shell, and the opening structure is elastically connected to the movable shaft through the shell.

[0015] The opening claw and guide limiter are connected to the movable shaft through the housing. The elastic connection between the housing and the movable shaft prevents damage to the container when the opening claw moves.

[0016] A further technical solution of this utility model is: the bottom of the outer shell is provided with a detachable threaded sleeve, and the opening claw is placed inside the threaded sleeve.

[0017] The lid-opening claws are easy to install and remove.

[0018] A further technical solution of this utility model is: a bottle holder for limiting the container is provided below the opening structure, and a soft pad is provided on the lower inner side of the bottle holder.

[0019] To further prevent damage to the container during the opening process.

[0020] The beneficial effects of this utility model are as follows: The drive mechanism of this utility model drives the connecting shaft and the opening structure to move. When the opening structure moves downward, it drives the movable shaft to move downward. When the movable shaft moves to the fixed seat limit, the opening structure is placed on the outer periphery of the container cap, and the protrusion contacts the upper surface of the container stopper. Then, the drive mechanism continues to drive the connecting shaft and the guide limit member in the opening structure to move downward, so that the opening claw closes and contacts the container cap, causing the container cap to deform and expand after being subjected to force, thus completing the opening action. This utility model can avoid manually opening the aluminum cap of the vial containing radioactive raw material, avoid direct contact between personnel and radioactive liquid, and can also be connected to the customer's entire production process to achieve fully automated production and meet the customer's process requirements.

[0021] This utility model has a guide assembly between the connecting shaft and the drive mechanism. The guide shaft in the guide assembly and the output end of the drive mechanism transmit force by abutting each other, which facilitates the docking between the drive mechanism and the cover opening assembly on the mounting base. During installation, the cover opening assembly can be installed as a whole, which is convenient and quick. A fixed bushing is sleeved on the outside of the guide shaft to ensure that the guide shaft drives the cover opening structure to move in the vertical direction, avoids deviation, and ensures that the cover opening structure moves accurately to the cover opening position. After the cover is opened, the drive mechanism retracts, and the cover opening assembly is reset by the reset component, and the cover opening device returns to the initial state.

[0025] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0026] Example 1:

[0027] Figure 1-2 An automatic container opening device is shown, comprising a drive mechanism 1, a connecting shaft 2, and an opening structure 3 connected in sequence. The opening structure 3 is connected to a movable shaft 4, and a fixed seat 5 for limiting the descent height of the opening structure 3 is sleeved on the outer periphery of the movable shaft 4. The opening structure 3 includes an opening claw 31 and a guide limiting member 32. The guide limiting member 32 contacts the inner wall of the opening claw 31. The bottom of the guide limiting member 32 is provided with a protrusion 35 that can contact the container stopper. The guide limiting member 32 is connected to the drive mechanism 1 through the connecting shaft 2 so that the protrusion 35 contacts the container stopper and the opening claw 32 opens the container stopper along the outer periphery of the container stopper.

[0028] In this embodiment, the automatic container opening device also includes a mounting base. The drive mechanism 1 is placed above the mounting base. The fixed base 5, the movable shaft 4, and the connecting shaft 2 are placed below the mounting base and are sequentially sleeved from the outside to the inside. A vertical guide component is provided between the output end of the drive mechanism 1 and the connecting shaft 2. The guide component is in contact with the output end of the drive mechanism 1.

[0029] The drive mechanism 1 moves downwards via the connecting shaft 2, driving the opening structure 3 and the movable shaft 4. During this downward movement, the movable shaft 4 is stopped by the fixed seat 5. At this point, the opening structure 3 has moved to the outer periphery of the container 8 lid. The drive mechanism 1 continues to transmit force to the opening structure 3, causing it to open the container 8 lid, thus completing the automatic opening of the container 8. Considering the distance between the opening device and the container's placement, the output of the drive mechanism 1 needs to transmit force via the connecting shaft 2. Therefore, this invention provides a connection between the connecting shaft 2 and the drive mechanism 1. The guide assembly transmits force by abutting the guide shaft 21 and the output end of the drive mechanism 1, facilitating the connection between the drive mechanism 1 and the cover opening assembly on the mounting base. This allows for the overall installation of the cover opening assembly, which is convenient and quick. A fixed bushing 22 is fitted outside the guide shaft 21 to ensure that the guide shaft 21 drives the cover opening structure 3 to move in the vertical direction, preventing deviation and ensuring that the cover opening structure 3 moves accurately to the cover opening position. After the cover is opened, the drive mechanism 1 retracts, and the cover opening assembly is reset by the reset component 6, returning the cover opening device to the initial state.

[0030] In this embodiment, a spring is sleeved on the outer periphery of the connecting shaft 2.

[0031] In this embodiment, a bushing 22 is fitted over the guide shaft 21, and a bushing is also fitted over the movable shaft 4. The bushing serves to ensure that the opening structure 3 descends vertically.

[0032] In this embodiment, the reset element 6 is a spring, which mainly serves to buffer and relieve force.

[0033] In this embodiment, the drive mechanism 1 is a lifting cylinder, which provides force to open the aluminum cover.

[0034] In this embodiment, the bushing 22 is placed at the end of the movable shaft 4 and the movable shaft 4 is movably connected to the bushing 22.

[0035] The vertical guide assembly and the connecting shaft 2 cooperate to transmit the force of the drive mechanism 1 to the opening structure 3. The bushing 22 in the vertical guide assembly is located at the end of the movable shaft 4, which can reduce the space occupation and further restrict the movement direction of the movable shaft 4 to prevent deviation. In order to avoid the movement interference between the movable shaft 4 and the bushing 22, the movable shaft 4 can move up and down along the bushing 22.

[0036] In this embodiment, the upper end of the movable shaft 4 is provided with a limiting shoulder 41, the middle of the inner side of the fixed seat 5 is provided with a limiting ring 51 that cooperates with the limiting shoulder 41, the lower inner side of the fixed seat 5 is provided with a mounting ring 52, and the reset member 6 is placed between the movable shaft 4 and the mounting ring 52.

[0037] As the movable shaft 4 moves downward, the limiting shoulder 41 contacts the limiting ring 51, and the limiting ring 51 restricts the movement of the movable shaft 4. At this time, the opening structure 3 moves to the outer periphery of the container 8 lid, and the drive mechanism 1 continues to move to drive the opening structure 3 to open the container 8 lid. The bottom of the fixed base 5 is provided with a mounting ring 52. The opening assembly can be reset by the reset piece 6 between the mounting ring 52 and the movable shaft 4.

[0038] In this embodiment, to ensure the effectiveness of opening the aluminum cap, the cooperation between the movable shaft 4 and the fixed seat 5 ensures that the opening claw 31 only contacts the rubber stopper of the vial during the opening action, avoiding contact with the vial body, thus preventing the vial from being crushed. At the same time, the opening angle of the opening claw 31 should not be too large, so that when the guide limiter 32 pushes against the aluminum cap and moves downward, it will not travel too far and crush the vial. At this time, the opening effect is optimal.

[0039] In this embodiment, the main function of the movable shaft 4 is to drive the cover opening structure 3 to descend so that it contacts the aluminum cover.

[0040] In this embodiment, the limiting shoulder 41 and the limiting ring 51 between the movable shaft 4 and the fixed seat 5 cooperate to limit the opening position and make the opening position accurate.

[0041] In this embodiment, the downward movement of the guide limiter 32 causes the opening claw 31 to close and contact the aluminum cover. The guide limiter 32 continues to move downward, causing the aluminum cover to deform and expand under force. The opening claw 31 can also cause the aluminum cover to deform and expand. At the same time, the movement trajectory of the opening claw 31 is parabolic, that is, it has an upward pulling force on the aluminum cover. The action of these three forces enables the rolled aluminum cover to be opened.

[0042] In this embodiment, an elastic element is provided between the opening claws 31.

[0043] To avoid damaging container 8 during the opening process.

[0044] In this embodiment, the opening structure 3 further includes a housing 33, and the opening structure 3 is elastically connected to the movable shaft 4 through the housing 33.

[0045] The opening claw 31 and the guide limiter 32 are connected to the movable shaft 4 through the housing 33. The elastic connection between the housing 33 and the movable shaft 4 prevents damage to the container 8 when the opening claw 31 moves.

[0046] In this embodiment, the bottom of the outer casing 33 is provided with a detachable threaded sleeve 34, and the opening claw 31 is placed inside the threaded sleeve 34.

[0047] The 31 opening claw facilitates the installation and removal of the cover.

[0048] In this embodiment, a protruding fixing pad is provided on the inner circumference of the bottom of the threaded sleeve 34. The fixing pad is used to provide a support point for the opening claw 31 to rotate.

[0049] In this embodiment, a pad is provided above the guide limiting member 32, and the connecting shaft 2 passes through the pad and connects to the guide limiting member 32.

[0050] In this embodiment, the diameter of the guide limiting member 32 first decreases and then increases from bottom to top. The bottom of the guide limiting member 32 is provided with a protrusion. During the downward movement of the guide limiting member 32, it contacts the inside of the opening claw 31.

[0051] In this embodiment, a bottle holder 7 for limiting the container is provided below the opening structure 3, and a soft pad is provided on the lower inner side of the bottle holder 7.

[0052] To further prevent damage to the container during the opening process.

[0053] In this embodiment, elastic elements are used between the cap opening claws 31 and between the outer shell 33 and the movable shaft 4 during the cap opening action. At the same time, a silicone pad is placed at the bottom of the vial holder 7, which plays a role in buffering and dissipating force, avoiding the risk of the vial breaking due to excessive force when opening the cap.

[0054] This automatic bottle cap opening device mainly consists of: an opening structure 3, a connecting shaft 2, a movable shaft 4, an opening fixing seat 5, a bushing 22, a reset component 6, and a drive mechanism 1. The drive mechanism 1 is a lifting cylinder, and the opening structure 3 is used to open the aluminum cap.

[0055] When the vial is placed in the open position, the opening lifting cylinder descends, causing the connecting shaft 2 to be stressed. After being stressed, the connecting shaft 2 drives the opening structure 3 and the movable shaft 4 to descend together to the open position. At this time, the movable shaft 4 contacts the limit of the opening fixing seat 5, fixing the opening position of the opening structure 3. At the same time, the protrusion 35 in the opening structure 3 presses against the rubber stopper on the end face of the aluminum cap. At this time, the opening lifting cylinder continues to descend, and the connecting shaft 2 continues to move downward, driving the guide limit part 32 downward, causing the opening claw 31 to close and contact the aluminum cap. After being stressed, the aluminum cap deforms and expands to complete the opening action. After the opening is completed, the lifting cylinder rises to complete the reset action.

[0056] The automatic lid-opening device in this invention can be applied to intelligent aseptic isolation technology product line equipment, running through the entire production process and meeting customer needs.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
