Special tension device used in detection of compressive capacity of medical dialyzing paper

Abstract

The invention relates to a special tension device used in the detection of compressive capacity of medical dialyzing paper. The special tension device comprises a piece of detection dialyzing paper, a circular tension rope and a tension support plate; a tension vertical plate is welded on the upper end surface of the tension support plate; a first fixing roller and a second fixing roller are respectively arranged on two sides of the upper end surface of the front side of the tension vertical plate; a third fixing roller and a fourth fixing roller are respectively arranged on two sides of the lower end surface of the front side of the tension vertical plate; the first fixing roller, the second fixing roller, the third fixing roller and the fourth fixing roller all play the role of transmitting the detection dialyzing paper; a limiting opening is formed in the middle of the tension vertical plate; two linear slide rails are symmetrically mounted on two end side walls of the limiting opening; two adjusting branch chains are symmetrically mounted between the two linear slide rails. The special tension device can realize an excellent tension function in the detection process of the compressive capacity of the dialyzing paper, and has the advantages that the requirement of manual regulation on tensile force is not required, the operation is simple and convenient, the degree of automation is high, the self-adjusting performance of tensile force as well as the tensioning performance is good, the applicable range is large and the like.

Description

technical field [0001] The invention relates to the technical field of medical dialysis paper manufacturing, in particular to a special tensioning device for testing the compression resistance of medical dialysis paper. Background technique [0002] Dialysis paper is mostly used in medical sterilization. One side is high-density polyethylene. It is mainly used for sterilization of some high-end third-class medical device blister packaging. The advantage of dialysis paper is that it can enter and exit steam, but it is impermeable. It can be sealed with a sealing machine from time to time; performance testing is always required before the new dialysis paper is produced and leaves the factory. The poorer the ability, the worse the toughness of the dialysis paper. When it is over-extruded or has a sharp part when packing, the dialysis paper with low toughness is easy to be punctured, which leads to sterilization failure. Compressive performance testing must be carried out befor...
