Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment, and in particular relates to an intermittent upper cover structure. Background Art

[0002] The intermittent cover structure is used to block and seal the bottle mouth to achieve automated operation. The existing cover structure is mostly composed of multiple sets of cams that move together. The cam facing the bottle mouth is provided with a vacuum adsorption structure. The bottle mouth is blocked by vacuum adsorption of the bottle plug or bottle cap during the up and down movement of the cam. The cam up and down lifting method requires manual tools to fine-tune the suction position of the plug, and automated operation cannot be achieved; the cam processing cycle is long and the processing precision is high, so the processing cost is relatively high.

[0003] Alternatively, multiple sets of servo motors and ball screws are used to achieve the up and down lifting method. A vacuum adsorption structure is set at one end of the ball screw to vacuum the bottle plug or bottle cap to seal the bottle mouth during the up and down lifting process of the cam. Using multiple sets of servo motor equipment is very costly and the procedure is relatively complicated. Utility Model Content

DETAILED DESCRIPTION

[0025] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] This embodiment discloses an intermittent cover structure, which is used to cover the bottle mouth to achieve the blocking and sealing of the bottle mouth, and can be used in the bottle mouth blocking in the pharmaceutical, food and daily chemical fields. Figures 1 to 5 As shown, it includes a first connecting platform 8 for fixing the first driving structure, the first connecting platform 8 is arranged on one side of the vibrating hopper 21, a second connecting platform 9 is arranged at the bottom of the vibrating hopper 21, the first connecting platform 8 and the second connecting platform 9 are arranged in parallel, and the vibrating hopper 21 is always in a vibrating state, and is used to convey the bottle mouth blocking structure to the first driving structure. The vibrating hopper 21 is a commercially available product and will not be described in detail here.

[0027] The first driving structure includes a cylinder 18, one end of which is fixedly connected to the top surface of the first connecting platform 8, and the other end extends vertically upward. A pressure rod 22 is coaxially arranged in the cylinder 18, and a through hole corresponding to the position of the pressure rod 22 is arranged on the first connecting platform 8. When the cylinder 18 is started, the pressure rod 22 penetrates the first connecting platform 8 and reciprocates up and down; a connecting pillar 26 is also arranged on the first connecting platform 8, and a connecting plate 23 with an opening 231 is connected to the bottom of the connecting pillar 26, and the opening is used to release the bottle mouth sealing structure. The bottle is placed under the opening 231 of the connecting plate 23, and the bottle mouth sealing structure is placed at the opening 231. The pressure rod 22 applies downward pressure to the bottle mouth sealing structure, and the bottle mouth sealing structure is buckled with the bottle mouth to achieve bottle mouth sealing. The opening 231 is hinged with an eccentric block 24. When no external force is applied, the eccentric block 24 closes the opening 231. The bottle mouth blocking structure is located above the eccentric block 24. When an external force is applied, the bottle mouth blocking structure moves downward, pushing the eccentric block 24 to rotate along the hinge point, opening the opening 231, releasing the bottle mouth blocking structure, and sealing the bottle mouth below the opening 231. Preferably, the eccentric block 24 is hinged at the opening 231 through a pin 5, which has a simple structure, is convenient for maintenance, and is easy to replace. The bottle mouth blocking structure can be a bottle stopper or a bottle cap.

[0028] Specifically, the eccentric block 24 consists of two pieces, which are stepped and symmetrically arranged at the opening 231. Figure 5 As shown, the M of the eccentric block 24 is regarded as the side with a smaller center of gravity, and the N of the eccentric block 24 is regarded as the side with a larger center of gravity. The side N of the eccentric block 24 with a larger center of gravity fits with the edge of the opening 231, and the side M with a smaller center of gravity faces the center of the opening 231. The sides M with smaller centers of gravity of the two eccentric blocks 24 fit with each other to close the opening 231. Under the action of external force, the side M with a smaller center of gravity is pushed downward, the opening 231 is opened, and the bottle mouth blocking structure is released.

[0029] In order to make the intermittent upper cover structure meet the needs of bottles of different heights, a lifting structure is connected to the bottom of the first connecting platform 8. The lifting structure moves up and down in the vertical direction. The distance between the connecting plate 23 and the bottle mouth can be adjusted according to the height of the bottle body, so that the distance between the connecting plate 23 and the bottle mouth is moderate, thereby achieving good sealing of the bottle mouth.

[0030] Specifically, the lifting structure includes lifting rods 14 used in groups, the lifting rods 14 penetrate the second connecting platform 9 and are connected to the first fixed platform 8, the bottom of the lifting rods 14 is connected to a lifting plate 12 that connects the two lifting rods 14 into one, the lifting plate 12 is horizontally arranged, the lifting plate 12 is connected with a screw rod 5, and the screw rod 5 is connected to the output shaft of the motor 1 through a coupling 3. When the motor 1 is started, the screw rod 5 is driven to rotate up or down, thereby driving the lifting plate 12 to rise or fall, and the lifting plate 12 moves while driving the lifting rod 14 to move up and down, so as to adjust the up and down position of the first fixed platform 8.

[0031] In order to stabilize the position of the screw rod 5 and prevent it from shaking, a screw rod fixing seat 6 is arranged on the screw rod, and the top of the screw rod fixing seat 6 is connected to the second connecting platform 9. An upper limit optical fiber 13 and a lower limit optical fiber 11 located below the upper limit optical fiber 13 are arranged on the screw rod fixing seat 6. The upper limit optical fiber 13 and the lower limit optical fiber 11 are used to limit the upper and lower movement limits of the lifting plate 12. If the lower limit optical fiber 11 or the upper limit optical fiber 13 is exceeded, the motor 1 does not rotate.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
