A grinding device for producing chitosan hemostatic material

Abstract

The invention relates to a grinding apparatus for producing a chitosan bleeding-stopping material. A purpose of the present invention is to effectively solve the problems of low safety performance, absence of overload protection, influence on production efficiency, and the like. The grinding apparatus comprises a base, wherein an outer shell is fixed on the upper end of the base, the base is rotatably connected to a grinding disk positioned inside the outer shell, a rotation shaft eccentric to the grinding disk is vertically arranged in the outer shell, a grinding roller positioned inside thegrinding disk is fixed on the lower end of the rotation shaft, the outer shell is rotatably connected to a transmission shaft, the middle of the transmission shaft is provided with a circular concavegroove, the surface of the circular concave groove is provided with a spline groove, the outer shell is provided with a slidable rotating shaft, the end portion of the rotating shaft is provided witha spline disk capable of sliding back and forth in the spline groove, a ring is rotatably connected in the transmission shaft, the inner surface of the ring is aligned to the surface of the circular concave groove, the inner surface of the ring is provided with the same key groove as the spline groove, a worm is fixed on the rotating shaft, the rotating shaft is sleeved with a compressing spring,a worm wheel engaged with the worm is fixed on the rotation shaft, a shielding plate sleeved and connected to the grinding disk is fixed on the outer shell, and an inner tooth ring positioned above the shielding plate is fixed on the upper end of the grinding disk.

Description

Technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a grinding device for producing chitosan hemostatic materials. Background technique [0002] Chitosan is a kind of natural polymer compound. Pure chitosan is a white translucent flake or powder solid, tasteless, odorless, non-toxic, and has good affinity with human cells without rejection. It has good biocompatibility, can be biodegraded, and has hemostatic effect. The hemostatic property of chitosan is that chitosan has a certain amount of charge, and its molecules can directly connect the red blood cells on the wound to promote blood coagulation. In order to achieve the hemostatic effect, chitosan is derived from the shells of marine shell animals, of which shrimp and crab shells are the main raw material for chitosan. During the extraction process of chitosan, the shrimp and crab shells need to be completely ground and crushed. It is conducive to the next step operation...
