Description

Technical Field

[0001] The present invention relates to the field of filling, and particularly to an intelligent quantitative filling machine. Background Art

[0002] As a key device in the liquid packaging process, filling equipment is widely used in the fields of food, medicine, chemical industry, etc. Existing filling equipment mostly adopts the method of pumping or pneumatic pushing to automatically inject liquid into the filling container, and then realizes the quantitative control of the liquid by controlling valves or metering components. However, there are still various problems in the existing technology during the filling process, which urgently need to be improved.

[0003] First of all, the current filling structure generally has the problem of unsealed openings. During the filling process, the liquid is likely to overflow from the filling port, especially more obvious in the case of high-speed or multi-head filling, affecting the filling cleanliness and packaging quality. Secondly, due to the relatively fast flow rate of the liquid during the filling process, bubbles are often generated. These bubbles not only cause errors in the filling volume, but also are easily misidentified as effective volume by the metering system, thus affecting the quantitative accuracy. In addition, the actual filling volume of the liquid is restricted by factors such as residual liquid in the pipeline and air compression, resulting in unstable control of the filling volume, and further affecting the overall production consistency.

[0004] In addition, in order to realize the sealing operation after filling, the existing system usually needs to be equipped with a complex displacement mechanism to transfer the filling container to the sealing station, increasing the complexity and manufacturing cost of the equipment structure, as well as the maintenance difficulty and floor space.

[0005] Therefore, there is an urgent need for a new type of filling device that can achieve precise quantitative filling without a traditional liquid filling device, avoid the generation of bubbles, and is convenient for sealing after filling. Summary of the Invention

Detailed implementation manners

[0032] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0033] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0034] As Figures 1-4 As shown, an intelligent quantitative filling machine of the present invention has the following specific implementation manners: The intelligent quantitative filling machine in this embodiment includes a bracket 1, and a support base plate 2 is arranged at the bottom of the bracket 1 to stably support the whole machine structure and ensure the stability during the filling process. A filling box 14 is rotatably arranged on the bracket 1, and a plurality of filling positions are respectively formed on the upper surface and the lower surface of the filling box 14, and a filling cylinder 13 is positioned and installed at each filling position to accommodate and quantitatively fill the liquid.

[0035] The filling box 14 is rotatably connected to the bracket 1 through support rotating shafts arranged on both sides thereof. One of the support rotating shafts is of a hollow structure, and the liquid inlet pipe 6 passes through it and is sealed by a sealing ring arranged outside the liquid inlet pipe 6 to ensure that no leakage occurs during the process of the liquid entering the filling box 14 from the outside. A driving motor 16 is installed outside the other support rotating shaft to drive the filling box 14 to rotate up and down around the rotating shaft, so as to adjust the filling position and facilitate the cleaning or replacement of the filling cylinder 13.

[0036] Between the upper and lower surfaces of the filling box 14, a gravity traction mechanism is arranged for sucking the filling liquid into each filling cylinder 13 by gravity. The gravity traction mechanism includes a counterweight plate 12, and a counterweight cavity 121 is arranged inside the counterweight plate 12. The weight can be adjusted by injecting a counterweight liquid (such as water or other liquids), so as to realize the control of the traction force for filling.

[0037] To ensure the accuracy and synchronization of the traction action, a traction rod is arranged at the position corresponding to each filling cylinder 13 on the counterweight plate 12, and a negative pressure suction cup 20 is installed at the end of the traction rod for adsorbing the movable base 22 inside the filling cylinder 13. When the counterweight plate 12 moves downward under the action of gravity, the negative pressure suction cup 20 adsorbs and pulls the movable base 22, so that the liquid in the filling box 14 is sucked into the filling cylinder 13 from bottom to top, realizing uniform, slow and bubble-free filling. A limit constriction can be arranged at the opening position at the bottom of the filling cylinder 13. When the movable base 22 moves to the limit constriction position, the movable base 22 stops moving when it reaches the limit constriction position, achieving the purpose of quantitative filling.

[0038] An opening is provided at the top of each filling cylinder 13, and a filling seal head 19 is arranged at its corresponding filling position. The filling seal head 19 can be inserted into the filling cylinder 13 to seal the opening at the top of the filling cylinder 13, ensuring that no liquid overflows during the filling process and effectively preventing impurities such as dust and particles from entering the filling cavity 131 body, thereby improving the cleanliness of the filling environment and the hygienic safety of the product.

[0039] A movable base 22 is arranged inside the filling cylinder 13. The movable base 22 can slide up and down in the filling cavity 131, and a sealing layer is arranged on its outer wall surface, so that it always maintains a good sealing state during the movement in the cavity. The movable base 22 is equivalent to a sealing piston part in this structure, and cooperates with the negative pressure suction cup 20 and the counterweight traction action to form a closed, clean and quantitative filling process.

[0040] To realize the accurate positioning of the filling box 14 during the filling operation, a positioning clamp 10 is fixedly installed on one side of each filling position. The positioning clamp 10 is of an open structure. When the filling cylinder 13 is buckled into the positioning clamp 10, it can be elastically expanded and clamped through its elastic structure, so as to realize the firm fixation of the filling box 14;

[0041] After the filling is completed, as the weight of the counterweight box increases, the filling cylinder 13 will be vertically pulled out of the positioning clamp 10 by using the counterweight box.

[0042] A number of telescopic guide rods 8 are arranged between the filling box 14 and the counterweight box. Each telescopic guide rod 8 includes a guide telescopic rod and a guide sleeve 9. One end of the guide telescopic rod is connected to a connecting ear 15 arranged on the filling box 14 or the counterweight box, and the other end can be inserted into the guide sleeve 9.

[0043] This structure can provide guiding and supporting functions during the up-and-down movement of the counterweight plate 12, prevent the counterweight plate 12 from shifting or shaking, and improve the traction stability.

[0044] In order to realize the real-time detection and control of the motion state of the counterweight plate 12, a sliding mounting bracket 4 is arranged on one side of the bracket 1, and an infrared induction probe 3 is installed on the sliding mounting bracket 4. The infrared induction probe 3 can sense the position state of the counterweight plate 12.

[0045] When the counterweight plate 12 descends to the preset position where filling is completed, the infrared probe will send a signal to the control host. After receiving the signal, the host controls the solenoid valve 7 to close, thereby blocking the passage of the liquid inlet pipe 6 and preventing continuous liquid inflow, ensuring the filling accuracy. The solenoid valve 7 is installed on the liquid inlet pipe 6. The liquid inlet pipe 6 is used to introduce external liquid into the filling box 14. The liquid source is stable and controllable, and it can be finely adjusted in cooperation with the control host.

[0046] In addition, in order to improve the sealing efficiency after filling, the traction rod adopts a foldable structure, including a first traction rod 17 and a second traction rod 18, which are connected by a hinge shaft 21, and a torsion spring is arranged at the hinge.

[0047] When the whole traction rod is outside the filling cylinder 13 and the traction is over, the torsion spring automatically makes an inclined angle form between the first traction rod 17 and the second traction rod 18, driving the filling cylinder 13 to form a certain inclined angle, creating a favorable angle condition for the subsequent sealing process, avoiding moving again, and simplifying the overall process.

[0048] To ensure that the weight of the counterweight plate 12 can be flexibly adjusted and the adaptability during the filling process, a liquid replenishing pipe 11 and a liquid discharging pipe are also arranged on the counterweight plate 12. One end of the liquid replenishing pipe 11 is communicated with the counterweight cavity 121 of the counterweight plate 12, and the other end is connected to an external water tank, and liquid is injected into the counterweight cavity 121 through a water pump. The liquid discharging pipe is used to discharge the liquid in the counterweight plate 12 after filling is completed or when it is not in use, facilitating cleaning and storage.

[0049] Through the setting of a sealed filling structure, a gravity traction mechanism, an intelligent induction control system, and a functional design with an automatically tiltable sealing angle, this intelligent quantitative filling machine realizes high-precision, bubble-free, and pollution-free liquid filling. At the same time, it has a compact structure, reliable operation, and good practicability and industrial application value.

[0050] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
