Description

Technical Field

[0001] The utility model relates to the technical field of cold compress patch production, in particular to a spraying device for cold compress patch production. Background Technique

[0002] The cold compress patch is improved based on traditional cold compress methods (such as cold water, ice water, alcohol, etc.). With the TDDS new drug release system prepared based on high molecular gel as the core, it consists of a backing layer, a gel layer, and an anti-sticking layer. By vaporizing the water and natural cooling components contained in the high molecular gel, heat can be taken away to achieve local cooling. The drug components are combined with the hydrogel, and through the hydration effect, the drug components can quickly penetrate the fat layer, penetrate into the subcutaneous tissue, reach the lesion site, act on the affected area, and achieve the effects of cold compress for pain relief, transdermal absorption, and sustained-release drug delivery.

[0003] For example, a spraying device for cold compress patch production (publication number: CN217664044U) includes a cylinder and a rotating disk. The output end of the cylinder is connected with a telescopic rod. One end of the telescopic rod is provided with a mounting plate. The bottom surface of the mounting plate is provided with a driving disk. A rotating groove is formed inside the driving disk. The inner side wall of the rotating groove is rotatably connected with a rotating rod. The rotating disk is mounted on the circumferential surface of the rotating rod. The bottom surface of the driving disk is provided with a nozzle. A connecting groove is connected between the nozzle and the rotating groove. A connecting plate is slidably fitted inside the connecting groove. The upper surface of the connecting plate is fixedly connected with a pressing block. A plurality of convex blocks are fixedly connected to the circumferential surface of the rotating disk. By setting the driving disk, the rotating groove, the rotating disk, the convex blocks, the nozzle, the connecting plate, and the pressing block, the rotating disk rotates cyclically to achieve intermittent spraying. By adjusting the rotation speed of the servo motor, the spraying interval can be flexibly changed, greatly improving the spraying efficiency and realizing the automatic spraying of the cold compress patch.

[0004] Based on the retrieval of the above patent and the discovery of the equipment in the existing technology, it is found that the design of quickly resetting the pressing block by the memory spring in cooperation with the fixing ring in the application of the above equipment has certain advantages in realizing quick reset and elastic potential energy conversion, but there are also some potential disadvantages. Although the memory spring has good elastic memory ability, after long-term use or under excessive load, it is prone to fatigue and aging phenomena, resulting in a decrease in the elastic recovery ability of the spring, thereby affecting the reset effect of the pressing block. In multiple uses or continuous operation, due to the fatigue accumulation and performance change of the spring, the consistency of the pressing block reset may become poor, making it difficult to ensure the accuracy of each reset, and thus causing the gel at the spraying part to be inconsistent after the pressing plate pressurizes the inside of the nozzle. Therefore, we need to propose a spraying device for cold compress patch production. Content of the Utility Model
