Fiber film bundle end face electrothermal sintering device

Abstract

The invention relates to a fibrous membrane end surface electric heating sintering device which comprises frames, a conveying mechanism, a clamping lifting mechanism and a heating mechanism. A first servo motor of the conveying mechanism is connected with a driving shaft through a reducer. A transmission chain provided with a plurality of trays is connected with a driving chain wheel and a driven chain wheel. A supporting seat of the clamping lifting mechanism is placed on the frames. A second servo motor is placed on the frames or the supporting seat. Two linear guide ways and a lead screw are placed on the supporting seat. The lead screw is connected with the second servo motor. A nut is placed on the lead screw and is connected with the linear guide ways through a shifting seat. A double-end synchronous cylinder placed on the shifting seat is connected with a supporting bracket. Infrared heating plates of the heating mechanism are placed on a support. The support is placed on a cross beam out side of the frames. Two infrared heating plates are symmetrically and oppositely placed along the centers of the frames. The fibrous membrane end surface electric heating sintering device is reasonable in structure. The fibrous membrane end tips are sintered and closed through an infrared heating field, and therefore sealing and filling quality and production efficiency can be improved.

Description

technical field [0001] The invention relates to an electrothermal sintering device for the end face of a fiber membrane bundle, which belongs to the technical field of blood purification manufacturing. Background technique [0002] Dimensional hemodialyzer is to introduce the patient's blood into the hemodialyzer, and use the solute concentration difference on both sides of the semi-permeable membrane to achieve the purpose of removing metabolites and toxic substances and correcting the disorder of water and electrolyte balance through osmosis, diffusion and ultrafiltration. In the production process of the hemodialyzer, the prepared hollow fiber membranes are first bundled, the two ends of the hollow fiber membrane bundles are cut flat and then installed in the cylinder body, and the hollow fiber membrane bundles are sealed by pulling the membrane and installing the process. The two ends are glued and sealed twice, and after the two ends of the hollow fiber membrane bundle ...

AI Technical Summary

Problems solved by technology

[0003] The sealing and filling process of Weihemodialyzer adopts the secondary glue injection process, so there are the above problems: 1. The ratio precision of the head glue is extremely high. Once there is a ratio error due to human or equipment reasons, it will be in the fiber Formation of toxic residues in membrane bundles with serious clinical consequences

2. The head glue is imported glue, which is not only expensive, but also makes the manufacturing cost of the dialyzer remain high

3. The secondary glue injection equipment is complicated and the production efficiency is low, which is not conducive to expanding the production scale and reducing production costs
