Description

Technical Field

[0001] The utility model relates to the field of laboratory equipment, in particular to a fully enclosed liquid rapid quantitative transfer and dispensing device. Background Art

[0002] A liquid dispenser is a device or tool used to accurately dispense or transfer liquids. Liquid dispensers are commonly used in laboratories, pharmaceutical manufacturing, food processing, and other fields to ensure that the amount of liquid taken out each time during the dispensing process is consistent. Liquid dispensers have the functions of sample preparation, laboratory reagent configuration, standard solution preparation, reagent pipetting, and sample analysis, and play a key role in the laboratory.

[0003] For example, the utility model patent with publication number CN221287894U and publication date July 9, 2024 discloses a liquid dispenser, including a base, a bracket fixedly provided on the upper surface of the base, a mixing container fixedly provided on the upper surface of the bracket, a stirring rod provided in the mixing container, and a first liquid outlet pipe fixedly connected to the bottom of the mixing container, the bottom of the first liquid outlet pipe fixedly passes through the bracket and is fixedly connected to a transfer pipe, the transfer pipe is fixedly connected to a liquid separation pipe and a second liquid outlet pipe, both the liquid separation pipe and the second liquid outlet pipe are equipped with valves, the bottom of the liquid separation pipe is fixedly connected to a filling head, and a separating funnel is provided at the bottom of the second liquid outlet pipe; the patent mixes the liquid evenly through the stirring rod, and the valves on different pipelines control the flow of the liquid to the separating funnel or the filling head, thereby realizing static liquid separation or mixed filling, and the operator can perform filling according to actual needs.

[0004] When an existing liquid dispenser dispenses liquid into a container, as the liquid dispenser injects liquid into the container, the liquid is easily splashed in the container under the action of gravity. The splashed liquid is likely to splash onto the discharge port of the liquid dispenser. Subsequently, when the liquid encapsulator leaves the container, the discharge port of the liquid encapsulator is directly exposed to the air. Since there is liquid on the surface of the liquid dispenser, dirt in the air is likely to adhere to the surface of the discharge port of the liquid dispenser. Therefore, during the next round of liquid dispensing, the splashed liquid washes away the dirt on the surface of the liquid dispenser. The dirt in the air is likely to enter the container along with the liquid, affecting the quality of the liquid in the container. Utility Model Content

[0005] The purpose of the utility model is to provide a fully enclosed liquid rapid quantitative transfer and packaging device to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0025] In order to make those skilled in the art better understand the technical solution of the present invention, Figure 1-4 , the utility model is further introduced in detail.

[0026] An embodiment of the present utility model provides a fully enclosed liquid rapid quantitative transfer and packaging device, including a frame 1, on which a conveying mechanism 2 and a packaging mechanism 3 are provided. The conveying mechanism 2 is used to transport a packaging vessel 4, and is characterized in that the packaging mechanism 3 includes a packaging part 31, and the packaging part 31 is used to inject liquid materials into the packaging vessel 4. A protective mechanism 5 is installed on the packaging part 31. When the packaging part 31 leaves the packaging vessel 4, the protective mechanism 5 is closed to protect the packaging part 31 from air pollution. When the packaging part 31 is inserted into the packaging vessel 4, the protective mechanism 5 is opened, and the packaging part 31 injects the liquid into the packaging vessel 4.

[0027] Specifically, the frame 1 is placed on the ground, wherein the conveying mechanism 2 can use a common crawler conveyor, the crawler conveyor transports the packaging vessel 4, the packaging vessel 4 is placed vertically on the crawler conveyor, and the opening of the packaging vessel 4 is placed upward, wherein the packaging mechanism 3 is located above the conveying mechanism 2, when the conveying mechanism 2 transports the packaging vessel 4 to the bottom of the packaging mechanism 3, the conveying mechanism 2 stops conveying, wherein the packaging mechanism 3 can use a filling nozzle with a quantitative valve and a liquid storage box containing the liquid to be filled to perform quantitative liquid packaging operations.

[0028] When the existing liquid filling equipment is filling liquid, the empty filling container 4 is first placed with the opening facing upward on the conveying mechanism 2 by manual or mechanical means, and then the conveying mechanism 2 conveys the empty filling container 4. When the filling container 4 follows the conveying mechanism 2 and moves to the bottom of the filling mechanism 3, the conveying mechanism 2 stops moving. At this time, the filling mechanism 3 fills a certain amount of liquid into the filling container 4, completing the quantitative filling process of the liquid.

[0029] Obviously, when the discharge port is extended into the sub-packaging vessel 4 for liquid filling, the liquid drips into the inside of the sub-packaging vessel 4, and liquid splashing is likely to occur. The splashed liquid is likely to splash to the position of the discharge port. However, when the liquid sub-packaging process is not performed, the discharge port on the sub-packaging mechanism 3 for discharging the liquid is directly exposed to the air, and is likely to adhere to dirt in the air. Therefore, when the splashed liquid flows from the surface of the discharge port back into the sub-packaging vessel 4, the dirt adhered to the discharge port is likely to be flushed into the sub-packaging vessel 4, affecting the quality of the liquid sub-packed in the tank of the sub-packaging vessel 4.

[0030] In order to solve the above problems, in this embodiment, the subpackaging mechanism 3 includes a subpackaging part 31, which is used to inject liquid materials into the subpackaging container 4, and a protective mechanism 5 is installed on the subpackaging part 31. When the subpackaging part 31 leaves the subpackaging container 4, the protective mechanism 5 is closed to protect the subpackaging part 31 from air pollution. When the subpackaging part 31 is inserted into the subpackaging container 4, the protective mechanism 5 is opened, and the subpackaging part 31 injects liquid into the subpackaging container 4. The inner wall of the protective mechanism 5 faces the liquid in the subpackaging container 4, and the outer wall of the protective mechanism 5 faces the bottle mouth of the subpackaging container 4. Even if the liquid splashes onto the protective mechanism 5, the liquid contacts the inner wall of the protective mechanism 5 and will not wash away the dirt on the outer wall of the protective mechanism 5, thereby ensuring the purity of the liquid in the subpackaging container 4.

[0031] Preferably, the packaging mechanism 3 further includes a linear telescopic member 32, the linear telescopic member 32 is used to drive the packaging portion 31 close to or away from the packaging container 4, the packaging portion 31 includes a liquid storage section 311 and a discharge section 312, the discharge section 312 is used to discharge liquid into the packaging container 4, the protective mechanism 5 includes a plurality of protective plates 51 sleeved on the outside of the discharge section 312, the plurality of protective plates 51 are arranged at intervals along the circumference of the discharge end, the protective plate 51 includes a fixed section 511 and a deflection section 512, the fixed section 511 is connected to the end of the liquid storage section 311, and the other end of the fixed section 511 is rotatably mounted with the deflection section 512. 12. A torsion spring 513 is provided at the connection between the deflection section 512 and the fixed section 511. When the torsion spring 513 is not under force, the deflection section 512 deflects in a direction away from the discharge section 312. The protective mechanism 5 also includes a limiting portion 52, which is used to limit the deflection of the deflection section 512. The limiting portion 52 includes a limiting frame 521 that is sleeved on the outside of the protective plate 51. The limiting frame 521 is connected to the liquid storage section 311 through a restoring spring 522. When the restoring spring 522 is not under force, the limiting frame 521 is located outside the connection position between the deflection section 512 and the fixed section 511 of the protective plate 51.

[0032] Specifically, the liquid storage section 311 and the discharge section 312 are arranged vertically up and down, and the discharge section 312 divides the liquid in the liquid storage section 311 into the sub-packaging container 4. In this embodiment, the number of the protective plates 51 is four, and the four protective plates 51 form a rectangular space outside the discharge section 312. In addition, the size of the limiting frame 521 is larger than the bottle mouth size of the sub-packaging container 4.

[0033] Therefore, in this embodiment, the steps of liquid packaging in the packaging container 4 are as follows:

[0034] First, an empty dispensing container 4 is placed on the conveying mechanism 2 with the opening facing upwards, either manually or mechanically. The conveying mechanism 2 then conveys the empty dispensing container 4. When the dispensing container 4 follows the conveying mechanism 2 and moves to the position directly below the dispensing mechanism 3, the conveying mechanism 2 stops moving and waits for liquid filling.

[0035] Subsequently, the linear telescopic member 32 begins to extend, and the linear telescopic member 32 drives the packaging portion 31 to move toward the packaging container 4, so that the discharge section 312 and the plurality of protective plates 51 are inserted into the packaging container 4. At this time, the limiting frame 521 is against the bottle mouth of the packaging container 4, and then the linear telescopic member 32 continues to extend, so that the restoring spring 522 connected to the limiting frame 521 is compressed, and the limiting frame 521 moves upward relative to the connection position of the deflection section 512 and the fixed section 511, that is, the limiting frame 521 leaves the connection position of the deflection section 512 and the fixed section 511, so that the torsion spring 513 releases the accumulated Due to the elastic potential energy, the deflection section 512 deflects in the direction away from the discharge section 312, and the deflection section 512 of the protective plate 51 is opened. The inner wall of the protective plate 51 faces the liquid in the sub-packaging vessel 4, and the outer wall of the protective plate 51 faces the bottle mouth of the sub-packaging vessel 4. Even if the liquid splashes onto the protective plate 51, the liquid contacts the inner wall of the protective plate 51 and will not wash off the dirt on the outer wall of the protective plate 51, thereby ensuring the purity of the liquid in the sub-packaging vessel 4. Subsequently, the discharge section 312 of the sub-packaging part 31 continues to discharge liquid into the sub-packaging vessel 4 until the sub-packaging vessel 4 is filled, completing the liquid sub-packaging process.

[0036] Obviously, since the multiple protective plates 51 are distributed in a rectangular shape, when the deflection section 512 of the protective plate 51 deflects in a direction away from the discharge section 312, a gap will appear between two adjacent protective plates 51. In order to prevent liquid from splashing into the outer surface of the deflection section 512 through the gap, preferably, a protective film 53 is provided between two adjacent protective plates 51. The protective film 53 is used to prevent splashed water from falling onto the outer surface of the deflection section 512, washing away the dirt on the outer surface of the deflection section 512, and contaminating the liquid in the packaging container 4.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
