[0002] With the rapid development of the medical aesthetics industry, the demand for medical aesthetics equipment is increasing. Gel mixing, a core process in the industry, directly impacts the quality of the final product, ensuring uniformity. After cross-linking, washing, and swelling, traditional gels resemble jelly but are more elastic. Conventional high-shear methods struggle to achieve uniform shearing, and filter bag grinding is often used, a method that is inefficient, time-consuming, and labor-intensive. Utility Model Content

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A gel shearing mechanism includes a mounting frame and a pressure plate barrel. An electric push rod is fixedly installed on the mounting frame. The end of the telescopic shaft of the electric push rod is connected to a pressure plate. The pressure plate is slidably connected in the pressure plate barrel. The pressure plate barrel is a cylindrical structure with upper and lower openings. A screen assembly is fixedly installed under the pressure plate barrel.

[0006] Preferably, an annular sealing groove is opened on the side surface of the pressure plate, a silicone O-ring is installed in the annular sealing groove, the outer surface of the silicone O-ring is wrapped with a PTFE outer layer, and the PTFE outer layer is in contact with the inner wall of the pressure plate barrel.

[0007] Preferably, a guide sleeve with an open lower end is fixedly installed below the electric push rod, the pressure plate is slidably connected in the guide sleeve, and the mounting flange at the lower end of the guide sleeve and the mounting flange at the upper end of the pressure plate barrel are connected and fixed by a first clamp.

[0008] Preferably, the screen assembly includes a flange shell and a mesh plate, the mesh plate is installed in the inner cavity of the flange shell, and the outer surface of the flange shell is fixed to the mounting flange at the lower end of the pressure plate barrel by a second clamp.

[0009] Preferably, the mesh plate is made of a supporting rib structure that is arranged crosswise with each other.

[0010] Preferably, a material receiving barrel is provided directly below the pressure plate barrel.

[0011] This utility model provides a gel shearing mechanism. It has the following beneficial effects: By controlling the telescopic shaft of an electric push rod to drive the pressure plate downward within the pressure plate barrel, the pressure plate can squeeze the gel material downward through the target screen assembly, where it is evenly cut into particles of similar size. This effectively ensures uniform shearing of the gel material, significantly improving product quality.

[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0019] Example 1, as Figure 1-3 As shown, a gel shearing mechanism includes a mounting frame 1 and a pressure plate barrel 2. An electric push rod 3 is fixedly installed on the mounting frame 1. The end of the telescopic shaft of the electric push rod 3 is connected to a pressure plate 4. The pressure plate 4 is slidably connected in the pressure plate barrel 2. The pressure plate barrel 2 is a cylindrical structure with upper and lower openings. A 50-mesh screen assembly 5 is fixedly installed under the pressure plate barrel 2.

[0020] Working principle:

[0021] During operation, the screen assembly 5 is first installed under the platen barrel 2, and then the gel to be sheared is placed in the platen barrel 2, and then the platen barrel 2 is aligned with the bottom of the platen 4, so that the platen 4 can be extended into the inner cavity of the platen barrel 2 by the driving force of the electric push rod 3, thereby controlling the extension of the telescopic shaft of the electric push rod 3 to drive the platen 4 to press down in the platen barrel 2, and then the platen 4 can be used to squeeze the gel material downward through the 50-mesh screen assembly 5, so that the gel material can be evenly cut into particles of similar particle size through the screen assembly 5, so as to effectively ensure the uniform shearing of the gel material, thereby significantly improving the product quality. Compared with the traditional filter bag grinding method, the utility model has a high degree of automation and can also greatly improve the shearing efficiency.

[0022] Example 2 is a further preferred solution of Example 1. Since the medical beauty industry has very high requirements for the purity of materials, that is, sterility and freedom from impurity contamination must be ensured, conventional piston rods are usually sealed with O-rings. However, O-rings have a large ductility, and when sliding back and forth, some particles are likely to fall off.

[0023] Therefore, if Figure 3 As shown, this embodiment has an annular sealing groove 6 formed on the side surface of the pressure plate 4, a silicone O-ring 7 installed in the annular sealing groove 6, and the outer surface of the silicone O-ring 7 is wrapped with a PTFE outer layer 8, which contacts the inner wall of the pressure plate barrel 2. By using the PTFE outer layer 8 to wrap the silicone O-ring 7, the PTFE outer layer 8 is in direct contact with the inner wall of the pressure plate barrel 2. The PTFE material has a high hardness and does not have much ductility compared to the O-rings we conventionally use. Therefore, while ensuring sealing, it can also ensure the sterility and free of impurity contamination of the material during the shearing process. In addition, by directly wrapping the PTFE outer layer 8 on the outer surface of the silicone O-ring 7, subsequent replacement work is also facilitated.

[0024] Example 3, as a further preferred embodiment of Example 1, a guide sleeve 9 with an open lower end is fixedly mounted below the electric push rod 3, the pressure plate 4 is slidably connected within the guide sleeve 9, and the mounting flange at the lower end of the guide sleeve 9 is fixedly connected to the mounting flange at the upper end of the pressure plate barrel 2 via a first clamp 10. Therefore, after the gel to be sheared is placed in the pressure plate barrel 2, the mounting flange at the upper end of the pressure plate barrel 2 can be directly aligned with the mounting flange at the lower end of the guide sleeve 9 and fixed via the first clamp 10, thereby achieving a quick connection between the pressure plate barrel 2 and the guide sleeve 9, ensuring that the pressure plate 4 can be directly guided by the guide sleeve 9 to quickly extend into the pressure plate barrel 2.

[0025] Example 4, as a further preferred embodiment of Example 1, the screen assembly 5 includes a flange shell 51 and a mesh plate 52. The mesh plate 52 is installed in the inner cavity of the flange shell 51. The outer surface of the flange shell 51 is connected and fixed to the mounting flange at the lower end of the pressure plate barrel 2 via a second clamp 11. Therefore, when it is necessary to install the screen assembly 5 to the lower end of the pressure plate barrel 2, it is only necessary to align the flange shell 51 with the mounting flange at the lower end of the pressure plate barrel 2 and then fix it via the second clamp 11, thereby achieving rapid installation and fixation of the screen assembly 5.

[0026] In this embodiment, the mesh plate 52 is made of a structure of cross-arranged supporting ribs to enhance its strength, thereby effectively ensuring that the mesh plate 52 is not easily deformed or damaged during long-term use.

[0027] Embodiment 5, as a further preferred embodiment of embodiment 1, a material receiving barrel 12 is provided directly below the pressing plate barrel 2. The sheared gel material can be directly collected through the material receiving barrel.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
