High-precision TPU medical sheet extrusion device

Abstract

The invention discloses a high-precision TPU (thermoplastic polyurethane) medical sheet extrusion device in the technical field of medical sheets, which comprises an outlet frame, a group of adjusting motors are fixedly arranged on the outer wall of the outlet frame, threaded lead screws are arranged at the output ends of the adjusting motors, and lead screw sliding blocks penetrate through the threaded lead screws in the circumferential direction through threads; stirring fan blades are driven to rotate through the airflow flowing effect of cold air, the stirring fan blades rotate to drive a stirring turbine to rotate, the TPU solution in an outlet frame is continuously stirred through rotation of the stirring turbine, and meanwhile in the rotating process of a transmission column, the rotating direction of an outer rotating blade is opposite to that of the stirring turbine; at the moment, the TPU solution inside generates turbulent flow in the rotating process of the outer rotating blade and the stirring turbine, and meanwhile, in the process that the stirring turbine is adjusted to ascend, the outer rotating blade is driven by the connecting frame to ascend together, so that the stirring turbine and the outer rotating blade are in a synchronous state; and therefore, the function of stirring and discharging internal bubbles to prevent influence on the quality of finished products is achieved.

Description

technical field [0001] The invention relates to the technical field of medical sheets, in particular to a high-precision TPU medical sheet extrusion device. Background technique [0002] In the current development of medical technology, the use of medical machinery reduces the difficulty of treatment for doctors. At the same time, medical tools also increase the sanitary environment of treatment, which is convenient for doctors to recycle after use. The most widely used material in the medical field is TPU, this kind of material, its main properties are wear-resistant and good elasticity, high load-bearing capacity, and convenient for recycling. [0003] At present, when manufacturing TPU medical sheets, air bubbles are easily generated in the molten raw materials of TPU medical sheets during the manufacturing process, and the fluidity of the molten raw materials is poor, so it is difficult to discharge the air bubbles, resulting in insufficient strength of the formed TPU me...

AI Technical Summary

Problems solved by technology

[0003] At present, when manufacturing TPU medical sheets, air bubbles are easily generated in the molten raw materials of TPU medical sheets during the manufacturing process, and the fluidity of the molten raw materials is poor, so it is difficult to discharge the air bubbles, resulting in insufficient strength of the formed TPU medical sheets. There is a problem of fracture; secondly, the TPU medical sheet containing air bubbles may have light refraction problems during use, which will cause visual deviations for medical staff, which may easily cause medical accidents
