Description

Technical Field

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

[0002] Medical cold compress patches have curative effects such as cooling and heat dissipation. Generally, they have high curative effects on patients with skin and soft tissue injuries, high fever, heat stroke, etc. A conveying mechanism is required in the production process of medical cold compress patches, which plays a crucial role in the processing of medical cold compress patches. It can efficiently transport the raw materials or semi-finished products of cold compress patches from one processing link to another to ensure the smooth progress of the production process.

[0003] For example, a conveying mechanism for cold compress patch processing with stability (publication number: CN217349991U), includes a machine base and a conveying mechanism. A conveying mechanism is arranged in the inner cavity of the machine base. A support frame is arranged on the top of the machine base. A pre-tightening wheel is arranged in the inner cavity of the support frame. Pressing mechanisms are arranged at both ends of the pre-tightening wheel. Lifting components are arranged at both outer ends of the support frame. The utility model relates to the technical field of medical cold compress patches. This conveying mechanism for cold compress patch processing with stability drives one of the bidirectional threaded rods to rotate by starting the driving motor. The bidirectional threaded rod drives the other bidirectional threaded rod to rotate through a belt pulley and a belt, thereby driving two groups of moving blocks to approach each other. With the hinged action between the first hinge seat, the second hinge seat and the support rod, the support frame is driven to rise, so that the distance between the pre-tightening wheel and the conveying mechanism can be driven, and thus the pre-tightening wheel can better play a pre-tightening role on the raw materials of cold compress patches.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that when the above equipment is applied, the height of the support frame and the pre-tightening wheel inside it is adjusted through the lifting component, there are problems of insufficient precision and inflexible adjustment method. When the lifting component adjusts the height, due to the wear, looseness or insufficient design precision of mechanical components, the adjusted height may not be accurate enough, which will affect the pre-tightening effect of the pre-tightening wheel on the raw materials of cold compress patches. Therefore, we need to propose a conveying mechanism for cold compress patch production. Content of the Utility Model
