Description

Technical Field

[0001] This utility model relates to the field of polymer material preparation technology, and in particular to a cross-linking molding device for composite gels. Background Technology

[0002] Hydrogels possess viscoelastic mechanical properties similar to living tissues and permeability to different types of molecules and cells, making them widely used in biomedical fields such as drug carriers and tissue engineering. However, when used as drug carriers, single-function hydrogels often cannot meet the needs of practical applications, thus requiring the use of hydrogels with different functional layers for composite applications.

[0003] A search revealed that utility model patent CN210911050U discloses a multilayer hydrogel molding device, which includes a confluencer with several branch channels, a connection port connected to the upper end of each branch channel, and a gel injector connected to the upper end of each connection port. An adjustment hole is provided in the radial direction of each branch channel, and a flow control bolt is provided in the adjustment hole.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious drawback is that when preparing multilayer hydrogels, i.e. composite gels, the operator first needs to use the push rod to move the piston out of the outer cylinder so that different hydrogel crosslinking precursor solutions can be added to the two outer cylinders through the top opening of the outer cylinder. Then, the two pistons are reset and pushed one after the other. The operation is cumbersome and significantly increases the difficulty of adding raw materials. It is not convenient to use in practice and will also reduce the preparation efficiency of composite gels.

[0005] Therefore, it is necessary to invent a cross-linking molding device for composite gels to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a cross-linking molding device for composite gels, which can automatically add the hydrogel cross-linking precursor solution during the piston plate's upward movement, eliminating the need to pull the piston plate out of the piston cylinder before adding the material. This reduces the difficulty of material addition and effectively improves the preparation efficiency of composite gels, resulting in better practical performance. This addresses the problem mentioned in the background art that, when preparing multilayer hydrogels, i.e., composite gels, the operator first needs to use a push rod to move the piston out of the outer cylinder so that different hydrogel cross-linking precursor solutions can be added to the two outer cylinders through the top opening of the outer cylinder. Then, the two pistons need to be reset and pushed sequentially. This operation is cumbersome, significantly increases the difficulty of adding raw materials, is inconvenient in practical use, and reduces the preparation efficiency of composite gels.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a cross-linking molding apparatus for a composite gel, comprising:

[0008] The installation mechanism is used to install two sets of unidirectional suction mechanisms;

[0009] A one-way suction mechanism, wherein two sets of one-way suction mechanisms are provided, and each set of one-way suction mechanisms includes a piston cylinder, a piston plate, a piston rod, a pull plate, and a suction tube;

[0010] The piston plate is slidably disposed vertically inside the piston cylinder; the piston rod is fixedly disposed on the top of the piston plate; the pull plate is fixedly disposed on the top of the piston rod; the suction tube is fixedly disposed through the bottom front of the piston cylinder; and a first one-way valve is disposed on the suction tube.

[0011] A one-way output mechanism is used to sequentially input two hydrogel crosslinking precursor solutions into a molding container.

[0012] According to at least one embodiment of the present disclosure, a crosslinking molding apparatus for a composite gel includes a mounting frame that is fixedly sleeved on the outside of two piston cylinders.

[0013] According to at least one embodiment of the crosslinking molding apparatus for composite gels of the present disclosure, the mounting mechanism further includes side plates and bottom plates, wherein two side plates are provided, the two side plates are respectively fixedly disposed at both ends of the bottom of the mounting frame, and the bottom plate is fixedly disposed at the bottom of the two bottom plates.

[0014] According to at least one embodiment of the present disclosure, a crosslinking molding apparatus for a composite gel includes a unidirectional output mechanism comprising two output tubes, each of which is fixedly disposed through the bottom of two piston cylinders.

[0015] According to at least one embodiment of the crosslinking molding apparatus for composite gels of the present disclosure, the one-way output mechanism further includes an outer jacket plate, which is fixedly sleeved on the outside of two output tubes, and a second one-way valve is provided on each of the two output tubes.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features two sets of one-way suction mechanisms. The input ends of two suction tubes are connected to two containers of hydrogel crosslinking precursor solutions, respectively. Two pull plates are then pulled sequentially. The pull plates, through a piston rod, cause the piston plate to move upwards. This upward movement generates negative pressure. Due to the constraint of the second one-way valve on the output tube, this negative pressure draws the hydrogel crosslinking precursor solution from the containers through the suction tubes, allowing it to enter the piston cylinder for storage. The pull plates are then pressed downwards, causing the piston plate to move downwards through the piston rod. At this point, due to the constraint of the first one-way valve on the suction tube, the two hydrogel crosslinking precursor solutions fall sequentially into the gel container through the two output tubes. Compared to existing similar devices, this invention automatically adds the hydrogel crosslinking precursor solution during the upward movement of the piston plate, eliminating the need to remove the piston plate from the piston cylinder before adding the solution. This reduces the difficulty of adding the solution and effectively improves the preparation efficiency of the composite gel, resulting in better practical performance. Attached Figure Description

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0027] like Figures 1-3 As shown, the cross-linking molding apparatus for the composite gel disclosed herein may include components such as an installation mechanism 1, a one-way suction mechanism 2, and a one-way output mechanism 3.

[0028] like Figure 2 As shown in this disclosure, the installation mechanism 1 includes an installation frame 11, side plates 12 and a bottom plate 13. The installation frame 11 is fixedly sleeved on the outside of the two piston cylinders 21. There are two side plates 12, which are respectively fixedly installed at the bottom ends of the installation frame 11. The bottom plate 13 is fixedly installed at the bottom of the two bottom plates 13.

[0029] This allows the gel container to be placed at the center of the base plate 13, directly below the two output tubes 31, thus facilitating the subsequent flow of the two hydrogel crosslinking precursor solutions into the gel container for molding.

[0030] like Figure 3 As shown, in a preferred embodiment, the one-way suction mechanism 2 is provided in two sets. Each set of the one-way suction mechanism 2 includes a piston cylinder 21, a piston plate 22, a piston rod 23, a pull plate 24, and a suction tube 25. The piston plate 22 is slidably disposed on the inner side of the piston cylinder 21 in a vertical direction. The piston rod 23 is fixedly disposed on the top of the piston plate 22. The pull plate 24 is fixedly disposed on the top of the piston rod 23. The suction tube 25 is fixedly disposed through the bottom front of the piston cylinder 21. A first one-way valve is provided on the suction tube 25.

[0031] like Figure 3As shown in this disclosure, the one-way output mechanism 3 includes an output pipe 31 and an outer sleeve 32. There are two output pipes 31, which are respectively fixedly installed through the bottom of two piston cylinders 21. The outer sleeve 32 is fixedly sleeved on the outside of the two output pipes 31. A second one-way valve is provided on each of the two output pipes 31.

[0032] By setting up the aforementioned one-way suction mechanism 2 and one-way output mechanism 3, the input ends of the two suction tubes 25 are respectively connected to two hydrogel crosslinking precursor solution containers. Subsequently, the two pull plates 24 are pulled one after another. After the pull plates 24 are pulled, the piston rod 23 drives the piston plate 22 to move upward. During the upward movement of the piston plate 22, a negative pressure is generated. Due to the restriction of the second one-way valve on the output pipe 31, the negative pressure draws the hydrogel crosslinking precursor solution inside the container through the suction tubes 25, thereby allowing the hydrogel crosslinking precursor solution to enter the piston cylinder 21 and be stored. After storing, the pull plate 24 is pressed down, and the pull plate 24 drives the piston plate 22 to move down through the piston rod 23. At this time, due to the restriction of the first one-way valve on the suction tube 25, the two hydrogel crosslinking precursor solutions fall into the gel container through the two output tubes 31 one after another. Compared with existing similar devices, the addition of hydrogel crosslinking precursor solutions can be completed automatically during the upward movement of the piston plate 22, so that the piston plate 22 does not need to be pulled out from the inside of the piston cylinder 21 before the feeding operation is performed. This reduces the difficulty of feeding and effectively improves the preparation efficiency of composite gel, resulting in better actual use effect.

[0033] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0034] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
