[0017] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown:
[0018] Example 1: A filling device for improving filling accuracy includes a workbench 1, a filling box 2 on the workbench 1, a conveying mechanism 15 in the filling box 2, both ends of the conveying mechanism 15 extending to the outside of the filling box 2, and an opening 3 on the filling box to facilitate the passage of the conveying mechanism 15.
[0019] The conveying mechanism 15 uses existing technology to transport the bottles to be filled to the front of the weighing device 4, and then the conveying mechanism 15 stops working.
[0020] Inside the filling box 2, there is a weighing device 4 located behind the conveying mechanism 15. Behind the weighing device 4, there are liftable support plates 5 at intervals. On the support plates 5, there are clamping mechanisms that can move back and forth.
[0021] A tank 6 is located directly above the weighing device 4 on the filling box 2. Below the tank 6 is a discharge pipe 8 with a valve 7 installed. A flow meter 9 is also installed on the discharge pipe 8.
[0022] The clamping mechanism moves above the conveying mechanism 15, clamps the bottle and moves it to the weighing device 4 for preliminary weighing;
[0023] After weighing, the clamping mechanism re-clamps the bottle body, and the support plate 5 moves upward until the bottle mouth is coaxial with the feed pipe 8 and leaves a very small gap. The diameter of the feed pipe 8 is smaller than the bottle mouth, so as to facilitate the filling of the injection into the bottle body.
[0024] Finally, in this embodiment, all the components mentioned above are controlled by a controller and connected to a display to show the specific data of each component in real time.
[0025] Example 2: A filling device for improving filling accuracy includes a workbench 1, a filling box 2 on the workbench 1, a conveying mechanism 15 in the filling box 2, both ends of the conveying mechanism 15 extending to the outside of the filling box 2, and an opening 3 on the filling box to facilitate the passage of the conveying mechanism 15.
[0026] The side of the conveying mechanism 15 is equipped with a photoelectric sensor 10 that is flush with the front and rear of the weighing device 4. The photoelectric sensor 10 is mounted on the workbench 1 via a vertical rod.
[0027] The bottles to be filled are conveyed to the front of the weighing device 4 by the conveying mechanism 15. When the bottles move to the photoelectric sensor 10, the conveying mechanism 15 stops working according to the setting of the photoelectric sensor 10.
[0028] Inside the filling box 2, there is a weighing device 4 located behind the conveying mechanism 15. Behind the weighing device 4, there are liftable support plates 5. The lower side of the support plate 5 is vertically provided with a first telescopic mechanism 11 fixed on the workbench 1. The support plate 5 is provided with a clamping mechanism that can move back and forth.
[0029] A second telescopic mechanism 12 is horizontally provided on the support plate 5 along the front-to-back direction, and the clamping mechanism is located at the telescopic end of the second telescopic mechanism 12.
[0030] The clamping mechanism includes a bidirectional cylinder 13 horizontally arranged in the left-right direction, and clamping plates 14 at both ends of the bidirectional cylinder 13.
[0031] A tank 6 is located directly above the weighing device 4 on the filling box 2. Below the tank 6 is a discharge pipe 8 with a valve 7 installed. A flow meter 9 is also installed on the discharge pipe 8.
[0032] The clamping mechanism moves above the conveying mechanism 15, clamps the bottle and moves it to the weighing device 4 for preliminary weighing;
[0033] After weighing, the clamping mechanism re-clamps the bottle body, and the support plate 5 moves upward until the bottle mouth is coaxial with the feed pipe 8 and leaves a very small gap. The diameter of the feed pipe 8 is smaller than the bottle mouth, so as to facilitate the filling of the injection into the bottle body.
[0034] Finally, in this embodiment, all the components mentioned above are controlled by a controller and connected to a display to show the specific data of each component in real time.
[0035] Working principle:
[0036] This device is located behind the filling equipment on the production line. When the material dosage in the main tank is insufficient, the resulting substandard products are placed on the conveying mechanism. The injections in this device come from different tanks of the same product. The conveying mechanism transports them into the filling box. Using a photoelectric sensor 10, when the bottle is conveyed to the front of the weighing device 4, the conveying mechanism stops, the two ends of the bidirectional cylinder 13 extend outwards, and the second telescopic mechanism 12 extends to its maximum stroke. Then, the bidirectional cylinder 13 drives the clamping plate 14 to clamp the bottle on the conveying mechanism 15, and the first telescopic mechanism 11 extends upwards to its maximum stroke. Afterwards, the second telescopic mechanism 12 retracts to its original position, so that the upper end of the bottle is aligned with the feed pipe 8. In contrast, the first telescopic mechanism retracts to its original position, placing the bottle on the weighing device 4. The bidirectional cylinder 13 releases the bottle clamp, facilitating the weighing device 4 to weigh it. After weighing, the bidirectional cylinder 13 drives the clamping plate 14 to clamp the bottle, and the first telescopic mechanism 11 moves the bottle upward to below the feed pipe 8. After the first telescopic mechanism 11 extends to its maximum stroke, there is only a very small gap between the bottle mouth and the lower end of the feed pipe 8, facilitating the feed pipe 8 to discharge the injection into the bottle. After filling is completed, the first telescopic mechanism 11 retracts to its original position, and the bidirectional cylinder 13 drives the clamping plate 14 to release the bottle clamp, thereby accurately measuring the filling dosage. Once the target is met, the bottle is moved to the conveying mechanism 15.
[0037] It should be noted that the stopping time of the conveying mechanism should be slightly longer than the operation time of this step, so as to allow the device enough time to fill bottles that are not filled to the required level. Also, the bottle falling onto the conveying mechanism should not block the action of the photoelectric sensor 10 again, so as not to affect the conveying mechanism 15.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
