Description

Technical Field

[0001] The present invention relates to the technical field of liquid packaging, in particular to a liquid packaging device. Background Art

[0002] In modern industrial production, liquid packaging is an essential and critical process in multiple industries, including pharmaceuticals, food, and cosmetics. Its efficiency, precision, and hygiene standards are directly linked to product quality and safety. Traditional liquid packaging processes rely primarily on valve structures, such as mechanical valves and liquid solenoid valves, to precisely control liquid flow. These valves directly act on liquid channels through physical means (such as mechanical motion or electromagnetic action) to open or close the liquid flow path, thereby enabling liquid packaging.

[0003] However, as the market's requirements for product hygiene standards continue to increase, the limitations of traditional valve body control methods are gradually becoming apparent. Specifically, these challenges are mainly reflected in the following aspects: Risk of microbial contamination: Components such as mechanical valve bodies and liquid solenoid valves can easily become breeding grounds for microorganisms when in contact with liquids for a long time. Especially when dealing with liquids with high viscosity, easy to precipitate, or containing microorganisms, it is difficult to completely clean the inside of the valve body, which increases the risk of microbial contamination of the product, thereby affecting the shelf life and safety of the product; Difficulty in cleaning and maintenance: Due to the complexity of the valve body structure, thorough cleaning becomes particularly difficult, especially when there are small gaps or hard-to-reach corners. This not only increases the time and cost of cleaning operations, but may also lead to cross-contamination of subsequent batches of products due to incomplete cleaning; therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be addressed.

They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0025] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0026] like Figure 1-Figure 2As shown, in one embodiment, a liquid filling device includes a driving mechanism, a packaging mechanism, a fixing mechanism and an electric-controlled valve mechanism. The electric-controlled valve mechanism is a hollow structure and forms a accommodating cavity. The packaging mechanism and the fixing mechanism are arranged in the accommodating cavity. The fixing mechanism is used to fix the sterile bag, and the driving mechanism is used to drive the packaging mechanism to perform reciprocating motion in the electric-controlled valve mechanism to fill the sterile bag.

[0027] Specifically, the fixing mechanism of the present application fixes the sterile bag, and the packaging mechanism continuously packages the sterile bag. The present application separates the packaging mechanism and the fixing mechanism, which can ensure that the sterile bag will not deviate during continuous opening and closing movements, and perform more accurate liquid separation.

[0028] Furthermore, it also includes a frame, and the liquid packaging device is installed on the frame. The frame fixes and supports the liquid packaging device, thereby facilitating liquid packaging.

[0029] like Figure 1-Figure 2 As shown, in one embodiment, the packaging mechanism includes a first guide rod fixing plate 11, an electric-controlled valve sealing stopper 12, a sealing guide rod 13, a sealing clamp movement guide plate 14, a sealing spring 15 and a second guide rod fixing plate 16. The first guide rod fixing plate 11 and the second guide rod fixing plate 16 are located at both ends of the accommodating cavity. The electric-controlled valve sealing stopper 12 is connected to the side of the first guide rod fixing plate 11 close to the second guide rod fixing plate 16. The two ends of the sealing guide rod 13 are respectively connected to the first guide rod fixing plate 11 and the second guide rod fixing plate 16. A sealing clamp movement guide plate 14 is slidably provided on the sealing guide rod 13. A sealing spring 15 is sleeved on the sealing guide rod 13. The sealing spring 15 is located between the sealing clamp movement guide plate 14 and the second guide rod fixing plate 16.

[0030] Specifically, a groove is provided on the first guide rod fixing plate 11 at a position corresponding to the sealing guide rod 13, and the end of the sealing guide rod 13 is embedded in the groove. A first through hole is provided on the sealing guide rod 13, and a second through hole is provided on the first guide rod fixing plate 11 at a position corresponding to the first through hole. When the end of the sealing guide rod 13 is embedded in the groove, the first through hole and the second through hole are coaxially arranged, and the pin is embedded in the second through hole and the first through hole in sequence to detachably connect the first guide rod fixing plate 11 and the sealing guide rod 13.

[0031] During operation, the driving mechanism abuts against the sealing clamp moving guide plate 14 and pushes the sealing clamp moving guide plate 14 toward the side of the electric control valve compartment door 42, so that the sealing clamp moving guide plate 14 is separated from the electric control valve sealing block 12, forming a liquid flow channel, so that the liquid to be packaged can flow evenly; when the liquid in the sterile bag reaches the preset value, the driving mechanism moves toward the side of the electric control valve fixed valve body 41, and the sealing clamp moving guide plate 14 returns to its original position under the action of the sealing spring 15, and is closed, thereby packaging the liquid.

[0032] like Figure 1-Figure 2 As shown, in one embodiment, two sealing guide rods 13 are provided, two sealing springs 15 are provided, the two sealing guide rods 13 are arranged in parallel, one end of the two sealing guide rods 13 is connected to the first guide rod fixing plate 11, and the other end of the two sealing guide rods 13 is connected to the second guide rod fixing plate 16, and a sealing clamp movement guide plate 14 is slidingly provided on the two sealing guide rods 13. The two sealing guide rods 13 are both sleeved with a sealing spring 15, and the two sealing springs 15 are both located between the sealing clamp movement guide plate 14 and the second guide rod fixing plate 16.

[0033] By providing two sealing guide rods 13 and two sealing springs 15, the sealing clamp moving guide plate 14 moves parallel to the first guide rod fixed plate 11, so that the sealing clamp moving guide plate 14 can be in close contact with the electric control valve sealing block 12 to achieve sealing.

[0034] like Figure 3 As shown, in one embodiment, the packaging mechanism also includes a soft glue sealing block 17, and the soft glue sealing block 17 is connected to the side of the sealing clamp movement guide plate 14 facing the first guide rod fixing plate 11. The soft glue sealing block 17 and the electric control valve sealing block 12 can fix the sterile bag.

[0035] Specifically, after one package is completed, the sealing clamp movement guide plate 14 returns to its initial position under the action of the sealing spring 15. At this time, the soft glue sealing block 17 is in close contact with the electric control valve sealing block 12 to achieve sealing. When the motor 51 drives the output shaft to rotate, the sealing push rod 55 moves toward the side of the electric control valve compartment door 42, and abuts against the packaging mechanism, so that the packaging mechanism also moves toward the side of the electric control valve compartment door 42, so that the soft glue sealing block 17 is separated from the electric control valve sealing block 12, forming a liquid flow channel, so that the liquid to be packaged can flow down evenly.

[0036] like Figure 1-Figure 2 As shown, in one embodiment, the fixing mechanism includes a top plate 21 of a pre-loaded pressing bag guide rod 25, a pressing bag spring 24, a pre-loaded pressing bag guide rod 25, a connecting rod 22 and a sterile bag pressing block 23. The two ends of the pre-loaded pressing bag guide rod 25 are respectively connected to the sealing clamp movement guide plate 14 and the second guide rod fixing plate 16. The top plate 21 of the pre-loaded pressing bag guide rod 25 is slidably set on the pre-loaded pressing bag guide rod 25. A pressing bag spring 24 is sleeved on the pre-loaded pressing bag guide rod 25. The pressing bag spring 24 is located between the top plate 21 of the pre-loaded pressing bag guide rod 25 and the second guide rod fixing plate 16. The top plate 21 of the pre-loaded pressing bag guide rod 25 is connected to one end of the connecting rod 22 on the side facing away from the second guide rod fixing plate 16. The other end of the connecting rod 22 passes through the sealing clamp movement guide plate 14 and is connected to the sterile bag pressing block 23.

[0037] The sterile bag of the present application adopts an inverted installation method. The process of fixing the sterile bag of the present application is: separating the sterile bag pressing block 23, the soft rubber sealing block 17 and the electric control valve sealing block 12, and then passing the bottom corner of one side of the sterile bag from bottom to top through the sterile bag pressing block 23, the soft rubber sealing block 17 and the electric control valve sealing block 12. Under the action of the bag pressing spring 24, the top plate 21 of the pre-installed bag pressing guide rod 25 moves toward the electric control valve sealing block 12, thereby driving the sterile bag pressing block 23 to contact the electric control valve sealing block 12, ensuring that the liquid can be sealed and then cut. At this point, the sterile bag is clamped in the pre-installed sealing clamp.

[0038] like Figure 1-Figure 2 As shown, in one embodiment, two bag pressing springs 24 are provided, two pre-loaded bag pressing guide rods 25 are provided, two connecting rods 22 are provided, and two sterile bag pressing blocks 23 are provided. One end of the two pre-loaded bag pressing guide rods 25 is connected to the side of the second guide rod fixing plate 16 facing the sealing clamp movement guide plate 14, and the other ends of the two pre-loaded bag pressing guide rods 25 pass through the pre-loaded bag pressing guide rod 25 top plate 21 and the sealing clamp movement guide plate 14 in sequence. The two pre-loaded bag pressing guide rods 25 are both sleeved with bag pressing springs 24, and the bag pressing springs 24 are located between the pre-loaded bag pressing guide rod 25 top plate 21 and the second guide rod fixing plate 16; both ends of the pre-loaded bag pressing guide rod 25 top plate 21 facing away from the second guide rod fixing plate 16 are connected to the connecting rods 22, and the other end of the connecting rods 22 passes through the sealing clamp movement guide plate 14 and is connected to the sterile bag pressing block 23.

[0039] Specifically, by setting two pre-loaded bag pressing guide rods 25 and two bag pressing springs 24, the top plate 21 of the pre-loaded bag pressing guide rod 25 moves parallel to the sealing clamp movement guide plate 14, so that the sterile bag pressing block 23 and the electric control valve sealing block 12 can be in close contact to achieve sealing.

[0040] Specifically, by setting two connecting rods 22 and two sterile bag pressing blocks 23, the top plate 21 of the pre-loaded pressing bag guide rod 25 moves parallel to the first guide rod fixing plate 11, so that the sterile bag pressing block 23 and the electric control valve sealing block 12 can be in close contact, so that the bottom corner of the sterile bag is pressed by the sterile bag pressing block 23 to ensure that the liquid can be sealed and then cut. At this point, the sterile bag is clamped in the pre-loaded sealing clamp.

[0041] like Figure 1-Figure 3 As shown, in one embodiment, an adjustment mechanism 3 is also included, and the adjustment mechanism 3 includes a threaded member, one end of the threaded member is located on the side of the second guide rod fixing plate 16 away from the sealing clamp movement guide plate 14, and the other end of the threaded member passes through the second guide rod fixing plate 16, the pre-loaded bag pressing guide rod 25 top plate 21 and the sealing clamp movement guide plate 14 in sequence, and the threaded member is threadedly connected to the pre-loaded bag pressing guide rod 25 top plate 21 and the sealing clamp movement guide plate 14.

[0042] Specifically, the threaded member is a hand screw, and one end of the hand screw located on the second guide rod fixing plate 16 close to the electric control valve compartment door 42 is a handle.

[0043] The process of fixing the sterile bag in the present application is: first turn the handle of the hand screw to move the sealing clamp motion guide plate 14 and the top plate 21 of the pre-loaded bag pressing guide rod 25 toward the second guide rod fixed plate 16, so that the sterile bag pressing block 23, the soft glue sealing block 17 and the electric control valve sealing block 12 are separated, and then the bottom corner of one side of the sterile bag is passed from bottom to top through the sterile bag pressing block 23, the soft glue sealing block 17 and the electric control valve sealing block 12, and the bottom corner of the sterile bag is manually adjusted to ensure smoothness and centering, and then the hand screw is loosened so that the bottom corner of the sterile bag is pressed by the sterile bag pressing block 23 to ensure that the liquid can be sealed and then cut. At this point, the sterile bag is clamped in the pre-loaded sealing clamp.

[0044] like Figure 1 As shown, in one embodiment, the electric control valve mechanism includes an electric control valve fixed valve body 41, an electric control valve compartment door 42, an electric control valve buckle 43, a first support seat 4411 and a second support seat 4421. The electric control valve fixed valve body 41 is formed with a first groove body 441 on the side facing away from the electric control valve compartment door 42, and the electric control valve compartment door 42 is formed with a second groove body 442 on the side facing away from the electric control valve fixed valve body 41. The first groove body 441 and the second groove body 442 form a receiving cavity, and the first groove body A first support seat 4411 is provided in the body 441, and the first guide rod fixing plate 11 is located on the first support seat 4411. A second support seat 4421 is provided in the second groove body 442, and the second guide rod fixing plate 16 is located on the second support seat 4421. One side of the electric control valve fixed valve body 41 is connected to one side of the electric control valve compartment door 42 through the electric control valve buckle 43, and the other side of the electric control valve fixed valve body 41 is hinged to the other side of the electric control valve compartment door 42 through the hinge structure 45.

[0045] The electric control valve mechanism serves as a control element, controlling the on-off of the fluid circuit according to a control signal (such as an electrical signal).

[0046] Specifically, the electric control valve buckle 43 includes a female buckle and a sub-mouth, one of the female buckle and the sub-mouth can be installed on one of the electric control valve fixed valve body 41 or the electric control valve compartment door 42; the other of the female buckle and the sub-mouth can be installed on the other of the electric control valve fixed valve body 41 or the electric control valve compartment door 42; when fixing the electric control valve fixed valve body 41 and the electric control valve compartment door 42, the electric control valve compartment door 42 is rotated around the hinge structure 45 until one side of the electric control valve fixed valve body 41 and one side of the electric control valve compartment door 42 are located on the same horizontal line, and the female buckle and the sub-mouth are overlapped and fixed.

[0047] Specifically, the first guide rod fixing plate 11 is set on the first support seat 4411, and the second guide rod fixing plate 16 is set on the second support seat 4421, so that the electric control valve mechanism is separated from the packaging mechanism and the fixing mechanism. The packaging mechanism and the fixing mechanism can be taken out from the electric control valve mechanism separately, so that the electric control valve mechanism has no contact with the liquid to be packaged and the sterile bag, avoiding contamination of the liquid to be packaged and the sterile bag by microorganisms remaining on the electric control valve mechanism, and realizing contactless liquid packaging.

[0048] like Figure 1 As shown, in one embodiment, the hinge structure 45 includes a limiting groove 451, a fixed shaft 452 and a hinge part 453. A limiting groove 451 is opened on the other side of the fixed valve body 41 of the electric control valve, and a limiting column is arranged in the limiting groove 451. A hinge part 453 is arranged on the other side of the electric control valve door 42. The hinge part 453 is annular and is sleeved on the outside of the fixed shaft 452. The other side of the electric control valve door 42 rotates around the fixed shaft 452.

[0049] Specifically, when fixing the electric control valve fixed body 41 and the electric control valve compartment door 42, rotate the electric control valve compartment door 42 so that the hinged portion 453 connected to the other side of the electric control valve compartment door 42 rotates around the fixed axis 452, thereby causing relative movement between the electric control valve compartment door 42 and the electric control valve fixed body 41 until one side of the electric control valve fixed body 41 and one side of the electric control valve compartment door 42 are on the same horizontal line, and the female buckle and the sub-mouth are overlapped and fixed.

[0050] like Figure 1 As shown, in one embodiment, the driving mechanism includes a motor 51, a motor fixing plate 52, a sealing movement guide plate 53, two fixed support ribs 54 and two sealing push rods 55, and the two side walls of the first trough body 441 are connected to one end of the two fixed support ribs 54 at one end away from the electric control valve compartment door 42, respectively, and the two ends of the motor fixing plate 52 are fixedly connected to the inner side walls of the two fixed support ribs 54, and the motor 51 is installed on the motor fixing plate 52, and the output shaft end of the motor 51 is connected to the sealing movement guide plate 53, and the two ends of the sealing movement guide plate 53 are fixedly connected to one end of the two sealing push rods 55, respectively, and the other ends of the two sealing push rods 55 pass through the bottom of the first trough body 441 and extend into the first trough body 441 to drive the packaging mechanism to perform reciprocating motion in the electric control valve mechanism.

[0051] Specifically, the motor 51 is a linear motor 51. The body of the motor 51 is fixedly arranged on a side of the motor fixing plate 52 away from the electric control valve mechanism. The output shaft end of the motor 51 passes through the motor fixing plate 52 and extends toward one side of the electric control valve mechanism. The output shaft end of the motor 51 is connected to the sealing movement guide plate 53. The output shaft of the motor 51 is a screw. The output shaft end of the motor 51 is threadedly connected to the sealing movement guide plate 53.

[0052] The two ends of the sealing movement guide plate 53 are respectively fixedly connected to one end of the two sealing push rods 55, and the other ends of the two sealing push rods 55 pass through the bottom of the first groove body 441 and extend into the first groove body 441;

[0053] The working principle of the driving mechanism is as follows: the motor 51 drives the output shaft to rotate, so that the sealing motion guide plate 53 performs reciprocating motion on the output shaft, and then drives the sealing push rod 55 to perform reciprocating motion in the first groove body 441. When the packaging mechanism has completed the packaging of a sterile bag, the sealing push rod 55 moves toward the side of the electric control valve compartment door 42, and abuts against the sealing clamp motion guide plate 14, so that the sealing clamp motion guide plate 14 also moves toward the side of the electric control valve compartment door 42, and the packaged sterile bags are separated from the unpackaged sterile bags. After that, the sealing push rod 55 moves toward the side of the electric control valve fixed valve body 41 until it is separated from the sealing clamp motion guide plate 14, and the sealing clamp motion guide plate 14 returns to its original position for the next packaging.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
